Abstract
Objective: To explore the application of modified urethral separation method in artificial urethral sphincter (AUS) implantation in patients with stress urinary incontinence (SUI), and its influence on the results of urethral pressure profilometry. Methods: A prospective collection of clinical data was conducted on 25 patients with stress urinary incontinence who underwent modified urethral separation method in AUS implantation and underwent urethral pressure profilometry in Beijing Hospital, Beijing Jishuitan Hospital Affiliated to Capital Medical University and the Second Hospital Affiliated to Tianjin Medical University from March 2019 to June 2023. The improved urethral separation method was to borrow part of the white membrane tissue of the cavernous body while freeing the dorsal side of the cavernous body of the urethra. The circumference of the urethra, sleeve size, and urethral pressure were recorded, the patient's autonomous urinary control before and after surgery and the changes of the international consultation on incontinence questionnaire-short form (ICI-Q-SF) score, incontinence quality of life questionnaire (I-QoL) score, urinary frequency score, nocturia score were compared. Follow-up was conducted in the clinic or by telephone at 1, 3, 6, and 12 months after activation of the device, and once a year thereafter. Local skin status and urine control were assessed, residual urine volume was measured by ultrasound and subjective score scale was completed. Results: All patients were male, aged 27-85 (65.8±15.7) years old. The circumference of the cuff used in this study was 4.0 cm in 4 patients (16.0%), 4.5 cm in 16 patients (64.0%), 5.0 cm in 4 patients (16.0%), and 5.5 cm in 1 patient (4.0%). Among them, the urethral circumference matched the cuff size in 14 cases (56.0%), the urethral circumference was smaller than the cuff size in 4 cases (16.0%), and the urethral circumference was larger than the cuff size in 7 cases (28.0%). Preoperative urodynamic examination showed that the maximum urethral pressure (MUP) was (78.0±25.9) cmH2O, (1 cmH2O=0.098 kPa) and the maximum urethral closure pressure (MUCP) was (53.4±26.6) cmH2O. The MUP of AUS device in the inactivated state was (88.0±26.5) cmH2O, which was not significantly higher than that before operation (P>0.05). The MUCP was (68.2±24.5) cmH2O, which was significantly higher than that before operation (P<0.05). The MUP and MUCP of the AUS device in the activated state were (146.6±25.2) cmH2O and (123.0±28.3) cmH2O, which were significantly higher than those before surgery and in the inactivated state (both P<0.001). All patients in the group reached the social urinary control standards at the first month of device activation. During a follow-up period of 2-50 months, 22 patients (88.0%) used the initial AUS device and all met social urinary control standards. The AUS device was replaced in 1 case. One patient died of cerebrovascular accident. One patient removed the device due to complications. The number of pads [M (Q1, Q3)] used in 25 patients before and after operation was 4.5 (3.0, 6.5) and 1 (0, 1) respectively, with statistically significant differences (P<0.001). ICI-Q-SF score, I-QoL score, urinary frequency score and nocturia score of 25 patients were significantly improved after surgery (all P<0.05). The incidence of postoperative complications was 20.0% (5/25), including 2 cases of painless hematuria, 1 case of infection, 1 case of urethral erosion, and 1 case of dysuria. Except for one patient who experienced urethral erosion and had his sleeve removed, the remaining four patients regained social urination control with active support treatment, and no symptoms recurred until the last follow-up. Conclusion: The modified urethral separation method has no significant effect on urethral pressure in patients with SUI, and can increase the volume of peri-urethral tissue in the cuff, thereby reducing the risk of intraoperative urethral injury and the incidence of postoperative urethral erosion.

Abstract
AIM To investigate the differences in retinal refraction difference values (RDVs) of adult patients with myopic anisometropia compared with those without myopic anisometropia, and to investigate the relationship between ocular biometric measurements and relative peripheral refraction. METHODS This clinical observation study included 130 patients with myopia (-0.25 to -10.00 D) between October 2022 and January 2023 aged between 18 and 40y. The patients were divided into anisometropia (n=63; difference in binocular anisometropia ≥1.00 D) and non-anisometropia (n=67; difference in binocular anisometropia <1.00 D) groups accordingly. Ocular biometric measurements were performed by optical biometrics and corneal topography to assess the steep keratometry (Ks), flap keratometry (Kf), axial length (AL), corneal astigmatism (CYL; Ks-Kf), surface regularity index (SRI), surface asymmetry index (SAI), and central corneal thickness (CCT). The RDV was measured at five retinal areas from the fovea to 53 degrees (RDV-0-10, RDV-10-20, RDV-20-30, RDV-30-40, and RDV-40-53), the total RDV (TRDV) of 53 degrees, and four regions, including RDV-superior, RDV-inferior, RDV-temporal, and RDV-nasal. An analysis of Spearman correlation was carried out to examine the correlation between RDV and the spherical equivalent (SE) and ocular biological parameters. RESULTS Within RDV-20-53, both groups showed relative hyperopic defocus, and the increase in RDV corresponds to the increase in eccentricity. In the myopic anisometropia group, the TRDV, RDV-20-53, RDV-superior, and more myopic eyes had significantly higher RDV-temporal values than less myopic eyes. (P<0.05). In the non-anisometropia group, there was no significant difference in the RDV between the more and less myopic eyes at different eccentricities (P>0.05). There was a negative correlation between SE and TRDV (r=-0.205, P=0.001), RDV-20-53 (r=-0.281, -0.183, -0.176, P<0.05), RDV-superior (r=-0.251, P<0.001), and RDV-temporal (r=-0.230, P<0.001), a negative correlation between CYL and RDV-10-30 (r=-0.147, -0.180, P<0.05), and a negative correlation between SRI and RDV-0-20 (r=-0.190, -0.170, P<0.05). AL had a positive correlation with RDV-20-30 (r=0.164, P=0.008) and RDV-temporal (r=0.160, P=0.010). CONCLUSION More myopic eyes in patients with myopic anisometropia show more peripheral hyperopic defocus. Diopter and corneal morphology may affect peripheral retinal defocus.

Abstract
Objective: To evaluate the prognostic value of left ventricular ejection fraction (LVEF) reserve assessed by gated SPECT myocardial perfusion imaging (SPECT G-MPI) for major adverse cardiovascular event (MACE) in patients with coronary artery disease. Methods: This is a retrospective cohort study. From January 2017 to December 2019, patients with coronary artery disease and confirmed myocardial ischemia by stress and rest SPECT G-MPI, and underwent coronary angiography within 3 months were enrolled. The sum stress score (SSS) and sum resting score (SRS) were analyzed by the standard 17-segment model, and the sum difference score (SDS, SDS=SSS-SRS) was calculated. The LVEF at stress and rest were analyzed by 4DM software. The LVEF reserve (ΔLVEF) was calculated (ΔLVEF=stress LVEF-rest LVEF). The primary endpoint was MACE, which was obtained by reviewing the medical record system or by telephone follow-up once every twelve months. Patients were divided into MACE-free and MACE groups. Spearman correlation analysis was used to analyze the correlation between ΔLVEF and all MPI parameters. Cox regression analysis was used to analyze the independent factors of MACE, and the optimal SDS cutoff value for predicting MACE was determined by receiver operating characteristic curve (ROC). Kaplan-Meier survival curves were plotted to compare the difference in the incidence of MACE between different SDS groups and different ΔLVEF groups. Results: A total of 164 patients with coronary artery disease [120 male; age (58.6±10.7) years] were included. The average follow-up time was (26.5±10.4) months, and a total of 30 MACE were recorded during follow-up. Multivariate Cox regression analysis showed that SDS (HR=1.069, 95%CI: 1.005-1.137, P=0.035) and ΔLVEF (HR=0.935, 95%CI: 0.878-0.995, P=0.034) were independent predictors of MACE. According to ROC curve analysis, the optimal cut-off to predict MACE was a SDS of 5.5 with an area under the curve of 0.63 (P=0.022). Survival analysis showed that the incidence of MACE was significantly higher in the SDS≥5.5 group than in the SDS<5.5 group (27.6% vs. 13.2%, P=0.019), but the incidence of MACE was significantly lower in the ΔLVEF≥0 group than in theΔLVEF<0 group (11.0% vs. 25.6%, P=0.022). Conclusions: LVEF reserve (ΔLVEF) assessed by SPECT G-MPI serves as an independent protective factor for MACE, while SDS is an independent risk predictor in patients with coronary artery disease. SPECT G-MPI is valuable for risk stratification by assessing myocardial ischemia and LVEF.

Abstract
Fermented Chinese medicine has long been used. Amid the advance for preservation of experience, the connotation of fermented Chinese medicine has been enriched and improved. However, fermented Chinese medicine prescriptions generally contain a lot of medicinals. The fermentation process is complicated and the conventional fermentation conditions fail to be strictly controlled. In addition, the judgment of the fermentation end point is highly subjective. As a result, quality of fermented Chinese medicine is of great difference among regions and unstable. At the moment, the quality standards of fermented Chinese medicine are generally outdated and different among regions, with simple quality control methods and lacking objective safe fermentation-specific evaluation indictors. It is difficult to comprehensively evaluate and control the quality of fermented medicine. These problems have aroused concern in the industry and also affected the clinical application of fermented Chinese medicine. This article summarized and analyzed the application, quality standards, and the modernization of fermentation technology and quality control methods of fermented Chinese medicine and proposed suggestions for improving the quality standards of the medicine, with a view to improving the overall quality of it.

Abstract
Objective: To explore the performance of a self-made venous-venous bypass (VVB) device for liver transplantation based on the principle of magnetic levitation drive. Methods: Experimental study was conducted from August 2020 to January 2022. Eight Bama minipigs underwent VVB of hepatic portal vein-femoral vein-internal jugular vein after occlusion of hepatic portal vein and inferior vena cava. The animals were divided into two groups according to the VVB devices used during VVB. A self-made VVB device was used in group A(n=5),and an imported VVB device was used in group B(n=3). The hemodynamic changes of the two groups of animals were compared at 6 time points including before vascular occlusion, during vascular occlusion, 30 minutes, 60 minutes, 90 minutes after the start of VVB, and 30 minutes after vascular opening. In addition,the changes of blood compatibility indexes,intestinal injury indexes,kidney injury indexes and internal environment indexes of the two groups of animals at each time point were compared. The independent samples t test was used for the quantitative data between the two groups with non-repeated measures,and the repeated measures analysis of variance was used for the quantitative data between the two groups with repeated measures. Results: During the VVB of the two devices,the venous drainage was sufficient,and the main manifestations were that the color of the intestine of the Bama miniature pig was ruddy, the peristalsis was normal, and the urine output was normal. There were no significant differences in hemodynamics,blood injure indexes,intestinal injury indexes,kidney injury indexes,neutropil gelatinase-associated lipocalin,and internal environment indexes(all P>0.05).The indexes at 30 minutes after vascular opening in the group A and the group B were as follows:mean arterial pressure were (71.0±7.7)mmHg(1 mmHg=0.133 kPa) and (74.0±8.7)mmHg,central venous pressure were (7.0±1.4)cmH2O(1 cmH2O=0.098 kPa) and (7.7±0.6)cmH2O,heart rate were (131±10) beats/minutes and (132±8)beats/minutes; red blood cell count were (6.43±0.89)×1012/L and (6.32±0.58)×1012/L,hemoglobin were (108.4±5.9)g/L and (110.0±3.5)g/L,free hemoglobin were (78.28±3.96)mg/L and (78.08±4.54)mg/L; intestinal fatty acid binding protein were (2.27±0.49)μg/L and (2.40±0.78)μg/L;creatinine were (68.30±9.77)μmol/L and (79.90±26.91)μmol/L,blood urea nitrogen were (3.94±1.39)mmol/L and (3.45±0.65)mmol/L;neutropil gelatinase-associated lipocalin were (4.02±0.53) μg/L and (3.86±0.23)μg/L;pH value were 7.27±0.04 and 7.23±0.03,lactic acid were (6.18±2.62)mmol/L and (4.30±0.50)mmol/L,concentrations of Na+ were (136.3±3.0)mmol/L and (137.6±1.6) mmol/L,concentrations of K+ were (3.89±0.42) mmol/L and (3.98±0.17)mmol/L,concentrations of Ca2+ were (1.40±0.03)mmol/L and(1.40±0.04)mmol/L;all indexes in the two group had no differences(all P>0.05). Conclusion: The self-made venous bypass device can be safely and effectively applied to VVB of Bama minipigs,and achieves the same performance as the imported venous bypass device.

Abstract
Tibetan medicine is an essential part of Chinese medicine and has unique theoretical experience and therapeutic advantages. According to the development principle of inheriting the essence, sticking to the truth, and keeping innovative, the supervision department should give clear and reasonable guidance considering the characteristics of Tibetan medicine, establish a standard system for quality control, clinical verification and evaluation, and accelerate the research and commercialization of new drugs. In view of the needs of drug supply-side reform and the current situation of Tibetan medicine and new pharmaceutical research, we ponder and provide suggestions on the confusion faced by the current supervision of Tibetan drug registration, hoping to contribute to the supervision strategy of Tibetan drug registration and the high-quality development of Tibetan medicine industry.

Abstract
Objective: To investigate the predicting value of different risk prediction models for short-term death in patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock and treated with extracorporeal membrane oxygenation (ECMO). Methods: This study was a retrospective case-control study. Forty patients with STEMI complicated by cardiogenic shock who hospitalized in the First Affiliated Hospital of Zhengzhou University from April 2017 to August 2021 and treated with percutaneous coronary intervention (PCI) and ECMO, were enrolled in this study. Patients were divided into survival group and death group according to their clinical outcomes at 30 days after ECMO implantation, and clinical data of the two groups were collected and analyzed. Receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were used to compare the predictive value of ACEF, AMI-ECMO, Encourage and SAVE risk scores for mortality at 30 days after ECMO implantation. According to the evaluation results of DCA, the optimal risk score was selected. Kaplan-Meier curve estimating the 30-day survival after ECMO implantation was plotted by grouping risk scores with reference to previous literatures. Results: A total of 40 patients with STEMI combined with cardiogenic shock were included, age was (57.4±16.7) years, 31 (77.5%) patients were male, there were 21 (52.5%) patients in the death group and 19 (47.5%) in the survival group. Compared with the survival group, patients in the death group had higher lactic acid values, higher proportion of anterior descending artery or left main artery lesions, and a higher proportion of acute renal failure and continuous renal replacement therapy during hospitalization (all P<0.05). Compared with survival group, ACEF, AMI-ECMO and Encourage scores were higher in death group, SAVE score was lower in death group (all P<0.05). The ROC curve analysis showed that the area under the curve (AUC) of ACEF, AMI-ECMO, Encourage and SAVE scores in predicting mortality were 0.707, 0.816, 0.757, and 0.677 respectively (P>0.05). ACEF score demonstrated the highest sensitivity (90.5%) and Encourage score exhibited the highest specificity (89.5%). DCA indicated that the AMI-ECMO and Encourage scores had the best performance in predicting the 30-day mortality after ECMO therapy. Kaplan-Meier survival curve analysis showed that the 30-day mortality after ECMO implantation increased with the increase of AMI-ECMO and Encourage scores (log-rank P≤0.001). Conclusions: The 4 scoring systems are all suitable for predicting 30-day mortality after VA-ECMO therapy in patients with ST-segment elevation myocardial infarction complicated by cardiogenic shock. Among them, AMI-ECMO and Encourage scores have better predicting performance.

Abstract
Objective: To investigate the efficacy and safety of the combination therapy with chemotherapy, programmed death-1 (PD-1) inhibitor and anlotinib in the treatment of advanced dedifferentiated liposarcoma (DDLPS). Methods: The clinical data of patients with dedifferentiated liposarcoma who received chemotherapy combined with PD-1 inhibitor and anlotinib in the Department of Medical Oncology, Zhongshan Hospital Affiliated to Fudan University from January 1, 2020 to November 30, 2021 were retrospectively analyzed. A total of 24 patients were included in this study, including 12 males and 12 females, with a median age of onset of 56 years (range, 31-69 years). Efficacy and safety in those patients were assessed. Results: All patients had unresectable or metastatic dedifferentiated liposarcoma with G2 (moderate differentiation) or G3 (differential differentiation) in a concise three-grade grading scheme of tumor pathology. Twelve patients received the regimen as the first-line treatment, while the other 7 taken the regimen as second-line treatment and 5 as third-line or above. The median follow-up time for overall survival (OS) was 7.7 months. The overall response rate (ORR) was 20.8% (5/24) and disease control rate (DCR) was 83.3% (20/24) with 5 partial response (PR), 15 stable disease (SD) and 4 progressive disease (PD). Overall, the median progression-free survival (PFS) was 4.9 months (95%CI: 3.4-16.2 months). The ORR of anthracycline-based, eribulin-based or gemcitabine-based regimens was 1/12, 2/6 and 2/6, respectively; and the median PFS was 7.7, 7.3 and 4.4 months, respectively. Waterfall plots showed notable tumor shrinkage of any degree in eribulin and gemcitabine-based regimens(3/6 and 2/6, respectively), while there were more patients presented with SD in anthracycline-based group(9/12). Common adverse reactions included myelosuppression, fatigue, anorexia, rash, pruritus, palpitate, hypothyroidism and hypertension. Conclusions: The combination regimen with chemotherapy, PD-1 inhibitor and anlotinib in the treatment of advanced DDLPS is effective and well tolerable. There are more responders in eribulin or gemcitabine-based regimens.

Abstract
Multiple types of liver diseases, particularly cholestatic liver diseases (CSLDs) and biliary diseases, can disturb bile acid (BA) secretion; however, BA accumulation is currently seen as an important incentive of various types of liver diseases’ progression. Da-Chai-Hu decoction (DCHD) has long been used for treating cholestatic liver diseases; however, the exact mechanisms remain unclear. Currently, our study indicates that the liver damage and cholestasis status of the α-naphthylisothiocyanate (ANIT)-induced intrahepatic cholestasis and bile duct ligation (BDL)-induced extrahepatic cholestasis, following DCHD treatment, were improved; the changes of BA metabolism post-DCHD treatment were investigated by targeted metabolomics profiling by UPLC-MS/MS. DCHD treatment severely downregulated serum biochemical levels and relieved inflammation and the corresponding pathological changes including necrosis, inflammatory infiltration, ductular proliferation, and periductal fibrosis in liver tissue. The experimental results suggested that DCHD treatment altered the size, composition, and distribution of the BAs pool, led the BAs pool of the serum and liver to sharply shrink, especially TCA and TMCA, and enhanced BA secretion into the gallbladder and the excretion of BAs by the urinary and fecal pathway; the levels of BAs synthesized by the alternative pathway were increased in the liver, and the conjugation of BAs and the pathway of BA synthesis were actually affected. In conclusion, DCHD ameliorated ANIT- and BDL-induced cholestatic liver injury by reversing the disorder of BAs profile.

Abstract
OBJECTIVE This study aimed to explore the effect and mechanism of chondrocyte apoptosis on the chemotaxis of osteoclast precursors (OCPs) during bone destruction. DESIGN The relationship between cartilage and bone destruction was verified with a rat temporomandibular joint osteoarthritis (TMJOA) model. The pan-caspase inhibitor Z-VAD-FMK (ZVAD) was applied to confirm the chemotactic effect of chondrocyte apoptosis on OCPs. Synthesis and release of the key chemokine CX3CL1 in apoptotic and non-apoptotic chondrocytes was assessed with IHC, IF, WB, and ELISA. The function of CX3CL1-CX3CR1 axis in the chemotaxis of OCPs was examined by CX3XR1 inhibitor AZD8797 (AZD) and si-CX3CL1. The regulatory effect of p38 MAPK on CX3CL1 release was verified by p38 inhibitor PH-797804. RESULTS A temporal and spatial association between cartilage degradation and bone resorption was found in the TMJOA model. The caspase-dependent chondrocyte apoptosis promoted chemotaxis of OCPs, which can be restrained by ZVAD. CX3CL1 was significantly upregulated when chondrocytes underwent apoptosis, and it played a critical role in the recruitment of OCPs, blockage of CX3CL1-CX3CR1 axis resulted in less bone resorption in TMJOA. P38 MAPK was activated in apoptotic chondrocytes, and had a regulatory effect on the synthesis and release of CX3CL1. After inhibition of p38 by PH-797804, the chemotactic effect of apoptotic chondrocytes on OCPs was limited. CONCLUSIONS This study indicates that apoptosis of chondrocytes in TMJOA enhances chemotaxis of OCPs toward osteoclast precursors through upregulation of the p38-CX3CL1 axis, thereby promoting the activation of local osteoclasts.

Abstract
Objectives: To evaluate the role of pancreas multidisciplinary team(MDT) clinic in the diagnosis of pancreatic diseases,patient compliance with MDT advice,and the impact of MDT on the postoperative survival of patients with pancreatic cancer. Methods: The study included 927 patients(554 males,373 females,aged (58.1±13.3)years (range: 15 to 89 years)) that had visited the pancreas MDT clinic of Zhongshan Hospital from May 2015 to December 2021,and 677 patients(396 males, 281 females, aged (63.6±8.9)years(range: 32 to 95 years)) who underwent radical surgery and with pathologically confirmed pancreatic adenocarcinoma from January 2012 to December 2020,of whom 79 patients had attended the pancreas MDT. The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate. The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model. Survival rates were compared using χ2 test. Results: Among the 927 patients that had visited the MDT clinic,233 patients(25.1%) were referred due to undetermined diagnosis. A direct diagnosis was made in 109 cases (46.8%,109/233) by the MDT clinic, of which 98 were consistent with the final diagnosis,resulting in an accuracy of 89.9%(98/109). The direct diagnosis rate in the recent years(36.6%(41/112),from June 2019 to December 2021) decreased compared to that in the previous years(56.2%(68/121),from May 2015 to May 2019),yet the accuracy in the recent years(90.2%,37/41) was basically the same as before (89.7%,61/68). The rate of compliance of the entire cohort was 71.5%(663/927), with the compliance rate in the recent two and a half years(81.4%,338/415) remarkably higher than that in the previous four years(63.4%,325/512). Patients with pancreatic cancer that attended the MDT exhibited a trend toward longer median postoperative survival than patients that did not attend the MDT,but the difference was not statistically significant(35.2 months vs.30.2 months,P>0.05). The 1-year and 3-year survival rates of patients that attended the MDT were significanly higher than patients that did not attend the MDT(88.6% vs. 78.4%,P<0.05;32.9% vs. 21.9%,P<0.05,respectively),but the 5-year survival rate was not statistically different(7.6% vs. 4.8%,P>0.05). Conclusions: The pancreas MDT clinic is an accurate and convenient way to diagnose intractable pancreatic diseases,and in the recent years the patients' compliance rate with MDT advice has increased. Pancreatic cancer patients that have attended the MDT have higher 1-year and 3-year postoperative survival rates,but the long-term survival benefits of MDT still needs to be proved by clinical studies on a larger scale.

Abstract
Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

Abstract
Hepatitis B virus (HBV) infection still remains a major public health issue in the Asia-Pacific region. Most of the burden of HBV-related disease results from infections acquired in infancy through perinatal or early childhood exposure to HBV in Asia-Pacific. Hepatitis B during pregnancy presents unique management issues for both the mother and fetus. These APASL guidelines provide a comprehensive review and recommendations based on available evidence in the literature, for the management of females with HBV infection through every stage of pregnancy and postpartum. These also address the concerns, management challenges, and required follow-up of children born to hepatitis B-positive mothers.

Abstract
Since the implementation of drug registration in China, the classification of Chinese medicine has greatly met the needs of public health and effectively guided the transformation, inheritance, and innovation of research achievements on traditional Chinese medicine(TCM). In the past 30 years, the development of new Chinese medicine has followed the registration transformation model of " one prescription for single drug". This model refers to the R&D and registration system of modern drugs, and approximates to the " law-abiding" medication method in TCM clinic, while it rarely reflects the sequential therapy of syndrome differentiation and comprehensive treatment with multiple measures. In 2017, Opinions on Deepening the Reform of Review and Approval System and Encouraging the Innovation of Drugs and Medical Devices released by the General Office of the CPC Central Committee and the General Office of the State Council pointed out that it is necessary to " establish and improve the registration and technical evaluation system in line with the characteristics of Chinese medicine, and handle the relationship between the traditional advantages of Chinese medicine and the requirements of modern drug research". Therefore, based on the development law and characteristics of TCM, clinical thinking should be highlighted in the current technical requirements and registration system of research and development of Chinese medicine. Based on the current situation of registration supervision of Chinese medicine and the modern drug research in China, the present study analyzed limitations and deficiency of " one prescription for single drug" in the research and development of Chinese medicine. Additionally, a new type of " series prescriptions" was proposed, which was consistent with clinical thinking and clinical reality. This study is expected to contribute to the independent innovation and high-quality development of the TCM industry.

Abstract
To learn the current situation and strengthen the management of national standards for Chinese medicinal materials, we sorted out the relevant national standards. According to incomplete statistics, there are 1 185 kinds of Chinese medicinal materials, including 1 024 kinds of plant medicines, 106 kinds of animal medicines, and 54 kinds of mineral medicines, in addition to ethnic medicinal materials with different functions. The relevant standards include 819 Pharmacopoeia standards, 342 standards issued by the Ministry of Health or National Medicinal Products Administration, 7 standards for new medicinal materials, and 17 standards for imported medicinal materials. In this paper, the sources of standards as well as the distribution of families and genera and the distribution of medicinal parts of medicinal materials are analyzed. The suggestions are as follows:(1)to improve the coordination among different national standards of Chinese medicinal materials;(2)to improve the standardization and controllability of relevant standards;(3)to revise the issued standards for Chinese medicinal materials(including Tibetan, Uygur, and Mongolian medicinal materials).

Abstract
In recent years, only a small number of new Chinese medicines have been approved for marketing, which has embodied the bottleneck in the development of the Chinese medicine industry. To tackle this problem, the National Medical Products Administration has issued a series of regulations and technical requirements. In the context of new regulations, this study deeply explored the research and development strategies of new Chinese medicines under the guidance of the new classification of drug registration, and discussed the key technical issues in the research and development.

Abstract
AIM To investigate the incidence of preoperative dry eye and related factors in patients undergoing corneal refractive surgery to correct myopia. METHODS A total of 141 patients with myopia who underwent corneal refractive surgery were surveyed by questionnaires, tear film break-up time (BUT) test, Schimer I test (SIt), corneal fluorescein staining (FL) test and diagnosed according to the currently recognized domestic diagnostic criteria for dry eye. Correlation analysis of factors such as age, gender, regular wearing of contact lens (CL), diopter (spherical equivalent), corneal thickness, and corneal curvature that may affect the onset of dry eye was carried out to clarify the main influencing factors. RESULTS There were 64 patients (45.39%) diagnosed with dry eye. The male patients (20.31%) was significantly less than that of non-dry eye subjects (41.56%; χ 2=7.260, P=0.007); the proportion of patients with dry eye wearing CL (81.25%) was significantly higher than that of non-dry eye subjects (51.95%; χ 2=13.234, P<0.001); the median diopter level of dry eye patients was -6.59 (IQR: -8.87, -4.58) D, and the median diopter level of non-dry eye subjects was -5.69 (IQR: -7.15, -4.03) D. The diopter level of dry eye patients was significantly higher (Z=-2.086, P=0.019). However, the age, best corrected visual acuity, and intraocular pressure of dry eye patients were not statistically different from those of non-dry eye subjects (t=-0.257, -0.383 and 0.778, P=0.798, 0.702, and 0.438); the corneal thickness and corneal curvature (K1 and K2) were also not statistically different either (Z=-1.487, -1.036 and -1.707, P=0.137, 0.300, and 0.088). The research further analyzes the three significant factors in the single factor analysis (gender, CL wear, and diopter) in a multi-factor way: CL wear and diopter were the influencing factors of dry eye disease. Among them, CL wear increased the risk of dry eye by 2.934 times compared with no CL wear; for every 1 D increase in diopter, the risk of dry eye increased by 0.761 times. CONCLUSION Preoperative dry eye is relatively common in patients who undergo corneal refractive surgery to correct myopia, especially in patients who have a history of CL wear and a high diopter level before surgery. Therefore, it is necessary to carry out preoperative screening and timely treatment of dry eye to obtain the best treatment outcome and postoperative satisfaction.

Abstract
Objective: To evaluate the effect of transfusion-free techniques on the prognosis of liver transplant patients. Methods: The recipients of adult liver transplantation at Tianjin First Central Hospital from August to December 2019 were included in the clinical observation. Liver transplantation without allogeneic blood transfusion was performed through anesthesia management techniques such as acute hemodilution or phlebotomy without volume replacement,maintaining decreased baseline central venous pressure and cell saver. According to the actual results,the patients were divided into two groups: transfusion-free group(n=21) and allogeneic transfusion group(n=28). There were 13 males and 8 females aged of (56.3±11.6) years in the transfusion-free group;and there were 16 males and 12 females aged (54.3±14.2)years in the allogeneic transfusion group. The transplant recipients who had not adopted transfusion management strategy from January to July 2019 were included as control group(27 males and 13 females,aged of (58.9±14.1)years). The clinical data of patients in perioperative period were collected to compare whether there were differences in the recovery of liver function and early complications among the three groups, one-way ANOVA test, rank-sum test, and χ2 test were used for data analysis. Results: The amount of intraoperative blood loss in both the transfusion-free group and the transfusion group was less than that in the control group((454.2±271.3)ml vs.(673.6±333.4)ml vs.(890.3±346.7)ml;q=-6.342,-5.286,both P<0.05).The duration of stay in ICU of the transfusion-free group was less than that of the transfusion group and control group((36.4±9.1)hours vs.(44.3±14.9)hours vs.(58.2±21.1)hours;q=-4.432,-3.824,both P<0.05).The mean ALT level at 7 days after operation was significantly lower in the transfusion-free group than in the control group((56.8±32.1)U/L vs.(89.6±45.6)U/L;q=-3.358,P<0.05). Conclusions: The improvement of multi-disciplinary transfusion management technology aimed at transfusion-free liver transplantation can effectively reduce intraoperative hemorrhage and help to avoid surgical transfusion. Transfusion-free liver transplantation is beneficial to the early postoperative recovery,and its long-term clinical significance is worthy of further clinical research.

Abstract
Objective: To investigate the effects of implantable Collamer lens (ICL) with a central hole on the accommodative function of patients with high myopia at different ages after implantation. Methods: A retrospective cohort study was conducted on 75 patients (150 eyes, 23 men and 52 women) with high myopia who underwent ICL implantation in Department of Ophthalmology of First Affiliated Hospital of Army Medical University from January 2017 to December 2018. The age was (28.99±7.26) years (range, 18-48 years). Forty patients (80 eyes) aged 18-34 years were included in the younger group and 35 patients (70 eyes) aged 35-48 years were included in the elderly group. To compare the changes and differences of accommodative function between the two groups, the uncorrected visual acuity, best corrected visual acuity, spherical equivalent error, amplitude of accommodation (AMP), negative relative accommodation (NRA), positive relative accommodation, single and both eyes' accommodation of facility (AF), fused cross cylinder, near and far distance horizontal phoria, accommodative convergence/accommodation and visual satisfaction questionnaire before surgery and at 1, 3, 6 and 12 months after surgery were analyzed. ANOVA for repeated design, LSD, unpaired sample t-test, Paired t-test, Chi-square test and Fisher's exact test were used for data analyses. Results: At each time point before and after operation, there were significant differences between the two groups in the AMP (F=16.511, P<0.05). The AMP of the younger group increased from (8.88±2.27) D at baseline to (9.51±1.34) D at 12 months, while it was decreased in the elderly group from (7.67±2.36) D at baseline to (6.56±2.63) D at 12 months. The trend of changes was significantly different (F=15.044,P<0.05). The AMP of the elderly group was significantly lower than that of the younger group at all time points (F=47.678, P<0.05). The NRA of the younger group was better than that of the elderly group (F=13.459, P<0.05), but the NRA had no significant changes in both groups postoperatively (F=1.788, P=0.141). We could not find any significant changes of positive relative accommodation between two groups (F=1.447, P=0.233). The monocular and binocular AF of two groups was increased significantly after surgery (F=34.296, 21.839, P<0.05). The AF of the younger group was better than that of the elderly group (F=80.327, 43.08, P<0.05). The fused cross cylinder was improved from baseline (0.12±0.32) D to (0.38±0.49) D at 12 months (F=4.752, P<0.05), while the difference was not found in the younger group (F=2.110, P=0.151). We could not find any significant changes of accommodative convergence/accommodation between two groups (F=0.389, P=0.505) or in each group (F=1.049, P=0.309) preoperatively and at 1, 3, 6 and 12 months after surgery. Conclusions: ICL implantation is effective in the treatment of high myopia. The visual acuity, AMP, monocular and binocular AF may increase obviously. Big improvements in the accommodative function and high satisfaction of vision can be achieved, especially in younger patients. (Chin J Ophthalmol, 2021, 57: 113-121).

Abstract
Objective: To evaluate consistency between 2-fold serial and 4-fold serial diluted neutralization tests against Enterovirus A71 (EV-A71) in estimating titer, Geometric mean titer (GMT), seroprevalence, and seroincidence. Methods: Based on a prospective cohort of 1-9 years old children, mothers and infants established in Anhua County, Hunan Province, during 2013-2018, from which 92 participants with a total of 386 blood specimens were sampled and tested with a 2-fold serial dilution and a 4-fold serial dilution neutralization tests against EV-A71 at the same time. Agreement was estimated using the Bland-Altman method. Stratified analysis was conducted to estimate effect dilution approach on GMT, seroprevalence and seroincidence. Results: The mean difference (0.04, 95%CI:-0.02-0.10) between the two dilution approaches was not significant. However, the limits of agreement (LOA) (-1.12-1.21), with the 95% confidence interval of upper LOA (1.10-1.31) and of lower LOA (-1.22--1.02), significantly exceeded the Clinic accept interval (-1, 1) indicating insufficient agreement between the two approaches in practice. While the dilution approaches did not affect estimates of GMT of the total population and the positive population, and seroincidence with seroconversion only, the differences were 2, 6 and 2%, respectively (P>0.05). Estimates of seroincidence with at least 4-fold increase and seroconversion/4-fold increase were significantly higher using a 4-fold dilution neutralization test compared to the 2-fold dilution neutralization test with 8% (95%CI: 1%-12%) and 9% (95%CI: 1%-17%), respectively. Conclusion: The 2-dilution and 4-dilution neutralization tests yielded comparable results when estimating the population's GMT; however, the difference between the two is not negligible when assessing the seroincidence.

Abstract
To investigate the characteristics and molecular events of dental pulp stem cells (DPSCs) for tissue regeneration with aging, we isolated and analyzed the stem cells from human exfoliated deciduous teeth (SHED) and permanent teeth of young (Y-DPSCs) and old (A-DPSCs) adults. Results showed that the stemness and osteogenic differentiation capacity of DPSCs decreased with aging. The RNA sequencing results showed that glycine, serine, and threonine metabolism was one of the most enriched gene clusters among SHED, Y-DPSCs, and A-DPSCs, according to analysis based on the Kyoto Encyclopedia of Genes and Genomes. The expression of serine metabolism-related enzymes phosphoserine aminotransferase 1 (PSAT1) and phosphoglycerate (PHGDH) decreased in A-DPSCs and provided less methyl donor S-adenosylmethionine (SAM) for DNA methylation, leading to the hypomethylation of the senescence marker p16 (CDNK2A). Furthermore, the proliferation and differentiation capacity of Y-DPSCs and SHED decreased after PHGDH siRNA treatment, which reduced the level of SAM. Convincingly, the ratios of PSAT1-, PHGDH-, or proliferating cell nuclear antigen-positive cells in the dental pulp of old permanent teeth were less than those in the dental pulp of deciduous teeth and young permanent teeth. In summary, the stemness and differentiation capacity of DPSCs decreased with aging. The decreased serine metabolism in A-DPSCs upregulated the expression of p16 via attenuating its DNA methylation, resulting in DPSC aging. Our finding indicated that serine metabolism and 1 carbon unit participated in stem cell aging, which provided new direction for stem cell aging study and intervention.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is a common malignancy of the head and neck. Long noncoding RNAs (lncRNAs) play essential roles in the development and treatment of LSCC. However, the role and regulatory mechanism of lncRNA small nucleolar RNA host gene 3 (SNHG3) in LSCC progression remain largely unknown. Twenty-five paired LSCC tissues and normal samples were collected. The expression levels of SNHG3, Yes-associated protein 1 (YAP1), and microRNA-340-5p (miR-340-5p) were measured via quantitative real-time polymerase chain reaction or western blot. Cell viability, apoptosis, and glycolysis were investigated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide, flow cytometry, and specific assay kit, respectively. The association between SNHG3 and miR-340-5p or miR-340-5p and YAP1 was assessed by dual-luciferase reporter assay. The expression of a protein involved in the Wnt/β-catenin pathway was detected by western blot. The xenograft model was established to assess the anti-cancer role of SNHG3 inhibition in vivo. We found that the levels of SNHG3 and YAP1 were increased but the miR-340-5p expression was decreased in LSCC tissues and cells. The knockdown of SNHG3 or YAP1 inhibited cell viability and glycolysis but induced apoptosis in LSCC cells. Overexpression of YAP1 reversed the effect of SNHG3 knockdown on LSCC progression. SNHG3 could regulate YAP1 expression by competitively binding with miR-340-5p. Overexpression of miR-340-5p suppressed cell viability and glycolysis but promoted apoptosis in LSCC cells. Knockdown of SNHG3 repressed Wnt/β-catenin pathway by regulating miR-340-5p and YAP1. The silencing of SNHG3 reduced LSCC xenograft tumor growth. In conclusion, knockdown of SNHG3 inhibited LSCC progression via inactivating Wnt/β-catenin pathway by regulating the miR-340-5p/YAP1 axis.

Abstract
As a newly epidemic, 2019 coronavirus disease (COVID-19) with a concentrated outbreak poses a great challenge to medical treatment. The severe and critical patients are complex complicatied with the psychological problems, and the medical staff are overworked and under tremendous psychological pressure. The surgeon participated in emergency medical rescue could provide professional treatment for the patients combined with surgical diseases, as well as specialized training for the non-surgeon crew, to reduce surgical-related mortality. With the advantages of good team consciousness, strong aseptic concept and good psychological quality, the surgeons can quickly adapt to and carry out rescue work under the premise of good self-protection. Surgeons need to develop critical care management concepts and focus on the critical care support equipment. Some suggestions are put forward for the standardized training of resident surgeons to cultivate compound talents. It is hoped that this article can lead to the thinking of how to participate in the emergency medical rescue of infectious diseases among surgeons and provide some enlightenment for future surgical education.

Abstract
Objective: To investigate mesopic contrast sensitivity (CS) and high-order aberrations after femtosecond laser-assisted LASIK (FS-LASIK), wavefront-guided femtosecond LASIK (WF-LASIK) and small incision lenticule extraction (SMILE) for myopia and astigmatism. Methods: In this case-control study, 212 eyes of 108 patients with myopia and astigmatism from September 2014 to September 2016 were treated by refractive surgery. There were 34 males (66 eyes) and 74 females (146 = eyes), aged 27 (24, 32) years. They were divided into 3 groups, with 37 patients (71 eyes), 35 patients (69 eyes) and 36 patients (72 eyes) treated by FS-LASIK, WF-LASIK and SMILE, respectively. Refraction diopters, corneal tomography, wavefront aberrations and contrast sensitivity were evaluated before and at 12 months after surgery. The results of different groups were compared by rank sum test. Results: At 12 = months of follow-up, 69 eyes (97.18%) treated by FS-LASIK, 67 eyes (97.10%) by WF-LASIK and 69 eyes (95.83%) by SMILE had the uncorrected distance visual acuity of 20/20 or better. Fifty-nine eyes (83.10%) treated by FS-LASIK, 60 eyes (86.96%) by WF-LASIK and 61 eyes (84.72%) by SMILE had better postoperative uncorrected distance visual acuity than preoperative corrected distance visual acuity. Surface regularity index of the WF-LASIK group decreased from 0.11 (0.07, 0.28) to 0.07 (0.06, 0.20) (Z=-2.662, P=0.008), which was less than that of the FS-LASIK and SMILE groups (Z=-3.236, -3.118, P=0.001, 0.000). Surface asymmetry index of the WF-LASIK group increased from 0.34 (0.25, 0.43) to 0.38 (0.30, 0.52) (Z=-2.140, P=0.032), which was less than that of the FS-LASIK and SMILE groups (Z=-2.910, -3.779, P=0.004, 0.000). The root mean square of high-order of the FS-LASIK group increased from 0.32 (0.27, 0.41) to 0.53 (0.40, 0.65) (Z=-6.228, P=0.000), which was more than that of the WF-LASIK and SMILE groups (Z=-3.595, -4.806, P=0.000, 0.000). Coma of the WF-LASIK group increased from 0.16 (0.11, 0.24) to 0.26 (0.15, 0.37) (Z=-3.816, P=0.000), which was less than that of the FS-LASIK group (Z=-3.528, P=0.000). Spherical aberration of the FS-LASIK and WF-LASIK groups increased from 0.10 (0.05, 0.21) and 0.08 (0.04, 0.12) to 0.24 (0.13, 0.34) and 0.15 (0.09, 0.26), respectively (Z=-5.141, -4.864, P=0.000, 0.000), which were more than that of the SMILE group (Z=-2.549, -4.682, P=0.011, 0.000). CS of the WF-LASIK group at 12 cycles per degree (c/d) increased from 1.34 (1.18, 1.48) to 1.48 (1.34, 1.63) (Z=-2.985, P=0.003), which was more than that of the FS-LASIK and SMILE groups (Z=-3.194, -2.977, P=0.001, 0.003). CS with glare of the WF-LASIK group at 12.0 c/d increased from 1.26 (1.18, 1.34) to 1.34 (1.34, 1.63) (Z=-3.608, P=0.000), which was more than that of the FS-LASIK and SMILE groups (Z=-4.033, -2.913, P=0.000, 0.004). Conclusions: FS-LASIK, WF-LASIK and SMILE achieved ideal visual outcomes at 12 months postoperatively. WF-LASIK treated eyes showed the best corneal symmetry, the least increase of high-order aberrations and the best visual quality among three kinds of surgeries.

Abstract
Severe inflammation, progressive cartilage, and bone destruction are typical pathologic changes in temporomandibular joint (TMJ) arthritis and lead to great difficulty for treatment. However, current therapy is inefficient to improve degenerative changes in progressive TMJ arthritis. This study investigated the therapeutic effects of human dental pulp stem cells (DPSCs) on severe inflammatory TMJ diseases. Progressive TMJ arthritis in rats was induced by intra-articular injection of complete Freund's adjuvant and monosodium iodoacetate. DPSCs were injected into the articular cavity to treat rat TMJ arthritis, with normal saline injection as control. Measurement of head withdrawal threshold, micro-computed tomography scanning, and histologic staining were applied to evaluate the severity of TMJ arthritis. Results showed that local injection of DPSCs in rats with TMJ arthritis relieved hyperalgesia and synovial inflammation, attenuated cartilage matrix degradation, and induced bone regeneration. Inflammatory factors TNF-α and IFN-γ were elevated in progressive TMJ arthritis and partially decreased by local injection of DPSCs. MMP3 and MMP13 were elevated in the arthritis + normal saline group and decreased in the arthritis + DPSCs group, which indicated amelioration of matrix degradation. The isolated primary synoviocytes were cocultured with DPSCs after inflammatory factors stimulated to explore the possible biological mechanisms. The expression of MMP3 and MMP13 in synoviocytes was elevated after TNF-α and IFN-γ stimulation and partially reversed by DPSC treatment in the in vitro study. The signal transducer and activator of transcription 1 (STAT1) was activated by inflammatory stimulation and suppressed by DPSC coculture. The upregulation of MMP3 and MMP13 triggered by inflammation was blocked by STAT1-specific inhibitor, suggesting that STAT1 regulated the expression of MMP3 and MMP13. In conclusion, this study demonstrated the possible therapeutic effects of local injection of DPSCs on progressive TMJ arthritis by inhibiting the expression of MMP3 and MMP13 through the STAT1 pathway.

Abstract
We note that most of the studies of the single photon scattering inside a one-dimensional coupled resonator waveguide are based on the waveguide coupling with the atom systems. In this paper, we will study the single photon scattering enabled by another system, i.e., the second-order nonlinearity, which can act as a single photon switch to control the single photon transmission and reflection inside the one-dimensional coupled resonator waveguide. The transmission rate is calculated to analyze the single-photon scattering properties. In addition, a more complicated second-order nonlinear form, i.e., three-wave mixing, is discussed to control single photon transmission inside the one-dimensional coupled resonator waveguide.

Abstract
Objective: To investigate the benzene concentration in the workplace of benzene-related enterprises in Yangzhou City from 2014 to 2018, and the abnormal blood routine of workers exposed to benzene, and to assess their occupational hazards. Methods: The environmental monitoring data of benzene-related enterprises and the health examination data of benzene exposed workers were collected in March 2019. The inhalation risk assessment model of the National Environmental Protection Agency (EPA) was used to assess the carcinogenic and non-carcinogenic risks of benzene workers. Results: The qualified rate of benzene detection in the workplace was 100% from 2014 to 2018, the highest concentration was 1.42 mg/m(3) in five years. The abnormal rates of blood routine detection in benzene exposed workers in five years was 7.10% (213/2 998) 、5.17% (218/4 214) 、5.61% (196/3 493) 、7.65% (288/3 767) 、7.83% (280/3 574) and 7.83%. respectively. The results of risk assessment showed that the minimum carcinogenic risk value was 7.56×10(-6) and the maximum carcinogenic risk value was 31.33×10(-6) in 2014-2018. The hazard quotient values were than 1. Conclusion: Benzene monitoring concentration in benzene-related enterprises in Yangzhou City from 2014 to 2018 was low, which meets the occupational exposure limit in China. However, the abnormal rate of blood routine in five years is still high, and there are both carcinogenic and non-carcinogenic risks. We should pay more attention to the health risk of workers exposed to low concentrat in benzene.

Abstract
Objective: To evaluate the role of multidisciplinary team (MDT) clinic in the diagnosis of pancreatic diseases and patient compliance with MDT advice in the current medical system. Methods: The study included 512 patients that had visited the pancreas-oriented MDT clinic of Zhongshan Hospital between May 2015 and May 2019.The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. Compliance was determined according to whether a patient received corresponding therapies or undergoing further checks or follow-ups. Results: Among the 512 patients that had visited the MDT clinic, 121 patients were referred due to undetermined diagnosis. Classified according to the final diagnosis, the rate of undetermined diagnosis in different disease categories from high to low in order was inflammatory diseases of the pancreas (75.0%, 24/32), other lesions of the pancreas (56.1%,23/41), pancreatic cystic lesions (19.1%,17/89), pancreatic carcinomas (18.3%,48/262) and pancreatic neuroendocrine neoplasms (pNEN)(10.2%,9/88). The MDT clinic made diagnosis to 68 patients directly with an accuracy of 89.7%. The rate of compliance in the entire cohort was 63.4%. The rate of compliance of patients from June 2017 to May 2019 (68.4%) was higher than that of patients from May 2015 to May 2017(59.6%). The compliance rate of patients in different disease categories from high to low in order was inflammatory diseases of the pancreas(84.4%, 27/32), pancreatic carcinomas (67.9%, 178/262), pNEN(60.2%,53/88), other lesions of the pancreas (56.1%,23/41), and pancreatic cystic lesions(49.4%, 44/89). The compliance rate of patients with different MDT advice from high to low in order was best supportive care(78.6%,22/28), antitumor approaches beyond surgery(71.6%,159/222), further tests(62.6%, 77/123), surgery(53.7%, 65/121) and follow-up(49.2%, 31/63). In patients suggested for surgery, the compliance rate of patients with carcinomas(67.4%, 33/49) was higher than patients with other kinds of neoplasms. Conclusions: MDT clinic could facilitate the diagnosis of pancreatic diseases conveniently and inexpensively. The overall compliance rate of MDT clinic patients is rather low, and patients with carcinomas have a relative high rate of compliance with the suggestion of surgery.

Abstract
We propose a formulation to obtain the exact susceptibility for system arbitrary operators to the external fields by means of the whole-system Hamiltonian (system plus reservoir) diagonalization methods, where the dissipative effects directly reflect the nature of the structured non-Markovian reservoir. This treatment does not make the Born-Markovian approximation in structured non-Markovian reservoir. The relations between linear response function and bound-states for the system as well as structured reservoir are found, which shows the photon bound-states and continuous energy spectrum can be readout from the susceptibility, respectively. These results are then used to examine the validity of second-order Born-Markovian approximation, where we find interesting features (e.g., bound-states) are lost in the approximate treatments for open systems. We study the dependence of the response function on the type (spectrum density) of interaction between the system and structured reservoir. We also give the physical reasons behind the disappearance of the bound-states in the approximation method. Finally, these results are also extended to a more general quantum network involving an arbitrary number of coupled-bosonic system without rotating-wave approximation. The presented results might open a new door to understand the linear response and the energy spectrum for non-Markovian open systems with structured reservoirs.

Abstract
Objective: To study the clinical characteristics of outpatients with hand, foot and mouth disease (HFMD) caused by different serotypes of enteroviruses. Methods: This was a prospective study. From February 2017 to March 2018, 563 outpatients with HFMD were enrolled by systematic sampling in the Department of Infectious Diseases, Henan Children's Hospital. Throat swabs were collected to determine the serotypes via PCR. Demographic, clinical, and laboratory data were collected by standard questionnaire. All cases were followed up twice at 2 and 9 weeks after the initial outpatient visit through telephone interview. A total of 563 cases were enrolled and 555 (98.6%) cases were positive for human enteroviruses, including 338 (60.9%) males. Analyses were stratified by enterovirus serotypes, Chi square test or Fisher's exact test, Rank sum test was used for comparison among different groups. Results: The age of 555 cases was 24.2 (16.4, 41.3) months. Among them 44.0% (224 cases) were identified as coxsackievirus (CV)-A6, while 189 cases, 35 cases, 14 cases and 73 cases were identified as CV-A16, enterovirus (EV)-A71, CV-A10 and other serotypes, respectively. Fever (≥37.5 ℃) was present in 51.4% (285/555) of laboratory confirmed cases. The proportions of fever in cases of CV-A6 (68.9%(168/244)) and CV-A10 (12/14) were significantly higher than those in cases of CV-A16 (31.7%(60/189),χ(2)=57.344,14.313,both P=0.000), other serotypes (43.8%(32/73),χ(2)=15.101 and 8.242, P=0.000 and 0.004) and EV-A71 (37.1%(13/35), χ(2)=13.506 and 9.441, P=0.000 and 0.002) respectively. There was no significant difference between CV-A6 and CV-A10 in presentation of fever (χ(2)=1.785, P=0.182). There were 359 cases (64.7%) with eruptions in mouth, hands, feet and buttocks. Cases infected with EV-A71 had the highest proportions (74.3%(26/35)) of rash emerging simultaneously in mouth, hands, feet, and buttocks. The proportion in cases of CV-A16, CV-A6, CVA10 and other serotype were 73.5% (139/189), 61.9% (151/244), 7/14 and 49.3% (36/73), respectively. The proportion of rash on other parts of body, such as face, limbs or torso in cases infected with CV-A6 (16.8% (41/244)) was the higherest and the proportion in cases of CV-A16, EV-A71, CV-A10 or other serotypes were 8.5% (16/189) , 5.7% (2/35) , 1/14, 6.8% (5/73) , respectively. None of these cases developed serious complications. Desquamation occurred in 45.5% (179/393) cases 7.5 (5.0, 9.0) days after disease onset and 13.5% (53/393) cases showed onychomadesis 31.0 (18.0, 33.5) days after disease onset. The proportion of desquamation and onychomadesis associated with CV-A6 (64.2% (95/148) and 31.8% (47/148)) was significantly higher than CV-A16 (31.8% (49/154) and 1.3% (2/154), χ(2)=33.601 and 52.482, both P=0.000) and other serotypes (38.0%(19/50) and 6.0%(3/50),χ(2)=10.236 and 12.988, P=0.001 and 0.000). Desquamation appeared more in cases of CV-A6 than in cases of CV-A10 (2/11,χ(2)=9.386, P=0.002), with the proportion of onychomadesis higher in CV-A6 than in EV-A71 (3.3% (1/30),χ(2)=11.088, P=0.001). Conclusion: Clinical manifestation such as fever, rash emerging parts, desquamation and onychomadesis are different among outpatient HFMD cases infected with CV-A16, CV-A6, EV-A71, CV-A10 and other enteroviruses.

Abstract
OBJECTIVE To investigate stability of skeletal hard tissues, dental hard tissues and soft tissues after orthodonticorthognathic treatment in a long term. This study reviewed longitudinal changes in orthodontic-orthognathic patients of skeletal class III malocculsion, using lateral cephalometric radiographs in 3-12 years after treatment in comparison to treatment finishing. METHODS Twenty-two patients with skeletal Class III malocclusion following orthodontic-orthognathic surgery in Peking University School and Hospital of Stomatology from January 1, 2000 to January 1, 2009 were observed. The lateral cephalometric radiographs of the following stages were collected: treatment finishing (T1), 3 to 12 years after treatment (T2). Statistical analyses of cephalometrics were evaluated. Paired student t test was performed by SPSS 17.0. RESULTS Data of all the 22 patients were studied in longitudinal timeline after treatment and 3-12 years after treatment. From T1 to T2, we evaluated 11-SN (angle between the upper incisors axis and SN plane), 11-NA angle (angle between the upper incisors axis and NA plane), 11-NA mm (perpendicular distance from upper incisors to NA plane), 11-41 (angle between the upper incisors axis and lower incisors axis), 41-NB angle (angle between lower incisors and NB plane), 41-NB (perpendicular distance from lower incisors to NB plane), 41-MP angle (angle between lower incisors and GoGn plane), and IMPA [angle between lower incisor and mandibular plane (tangent line to submandibular border)]. Most hard tissues of the teeth remained stable but upper anterior teeth angulations decreased, indicating by significantly reducing 11-SN (T1: 110.98°±6.77°; T2: 109.21°±5.80°; P=0.005); reducing 11-NA (T1: 28.31°±6.80°; T2: 26.49°±6.18°; P=0.002); increasing 11-41 (T1: 123.51°±8.14°; T2: 125.7°±10.01°; P=0.035). From T1 to T2, we also evaluated SNA (angle of sella-nasion-A-point), SNB (angle of sella-nasion-B-point), ANB (angle of A-point-nasion-B-point), GoGn-SN (angle between GoGn and SN plane), GoGn-FH (angle between GoGn and Frankfort plane), Y axis (angel between Sella-Gn and Frankfort plane), N-ANS (distance from nasion point to ANS point), ANS-Me (distance from ANS point to Menton point), N-Me (distance from nasion point to Menton point), ANS-Me/N-Me% (proportion of ANS-Me to N-Me), and FMA (angle between Frankfort and mandibular plane), Wits appraisal (horizontal distance between points A and B on functional occlusal plane). Skeletal hard tissues also remained relatively stable, only N-Me value changed significantly with a decreasing facial height (T1: 124.98°±11.98°; T2: 122.4°±11.05°; P=0.024). From T1 to T2, we finally evaluated FH-NsPg angle (angle between NsPg and Frankfort plane), H angle (angel between H line and NB), FH-A'UL angle (angle between A'UL and Frankfort plane), FH-B'LL angle (angle between B'LL and Frankfort plane), UL-LL (angle between UL and LL), UL-EP (distance between UL and E line), LL-EP (distance between LL and E line), Sn-H (perpendicular distance between Sn point and H line), Nls-H (distance of nose-lip-sulcus to H line), Li-H (lower lip to H line), Si-H (lower lip sulcus to H line), and NLA (nasolabial angle, angle of Cm-Sn-UL-point). Soft tissues changes were observed in decreasing UL-EP [T1: (-2.78±2.20) mm; (-3.29±2.44) mm; P=0.02] and H angle (T1: 8.27°±3.71°; 7.32°±3.83°; P=0.006). Other soft tissues remained relatively stable by retruding upper lip position and chin changes with no statistical significance. CONCLUSION Orthodontic-orthognathic treatment can improve esthetics and occlusal function in patients of skeletal class III malocclusion with a stable long-term outcome.

Abstract
Objective: A retrospective analysis of the predictive value of acoustic radiation force impulse (ARFI) elastography for esophageal varices in post-hepatitis B cirrhosis patients. Methods: 124 patients with post-hepatitis B cirrhosis who were admitted to Tianjin Second People's Hospital from August 2016 to August 2017 were selected. According to the shape of esophageal varices under gastroscopy and the risk of bleeding, patients were divided into 4 groups, none, mild, moderate and severe. In ARFI mode, the VTQ function was used to detect the VTQ values of the liver and spleen. The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the diagnosis of esophageal varices by VTQ values of the liver and spleen. Analysis of variance was performed on the data between the groups, and χ (2) test was performed for categorical data. Results: The difference in liver VTQ values between groups were statistically significant (F = 12.623, P < 0.01). There was a statistically significant difference in VTQ values between spleens (F = 9.022, P < 0.01). The liver VTQ predicts that the AUC value of mild esophageal varices in patients with cirrhosis was 0.701 (0.575-0.827); moderate varices was 0.802 (0.701-0.902); severe varices was 0.885 (0.784-0.986). The best cutoff value was 2.235, the specificity was 97.37%, the negative predictive value was 88.10%, and the accuracy was 90.16%. The VTQ value of spleen predicts the AUC value of mild esophageal varices in patients with liver cirrhosis was 0.688 (0.539-0.798); moderate varices were 0.762 (0.651-0.873); severe varices were 0.800 (0.671-0.928). The best cutoff value was 2.885, the specificity was 84.21%, and the negative predictive value was 82.05%. Conclusion: The application of ARFI elastography in the determination of VTQ values of liver and spleen has certain predictive value for esophageal varices and it might be useful for primary screening of esophageal varices in post-hepatitis B cirrhosis patients.

Abstract
It is complicated to decide the treatment plan of hopeless anterior teeth in esthetic zone due to severe periodontitis, periodontal-endodontic combined lesion or teeth trauma. The optional treatment plan for this kind of teeth includes retention after periodontal treatment, extraction and implant treatment, extraction and prosthodontic treatment and so on. To make an appropriate treatment plan, patients' periodontal conditions, periodontal biotype, local anatomy, esthetic demand, economic condition and social psychological status should be comprehensively considered. A combine of periodontal, endodontic and orthodontic therapy may achieve a good treatment effect in hopeless anterior teeth with severe periodontal destruction, tooth extrusion and occlusal trauma. In this case, a 20-year-old female who presented with symptoms of bleeding on brushing and upper incisors loosening for 1 month came to the Department of Periodontology, Peking University School and Hospital of Stomatology. The clinical examinations revealed that the patient's right upper incisor had signs of mobility (III°), intrusion of 1-2 mm, and probing depth (PD) of 9-10 mm. The periapical radiograph showed that the alveolar bone of right upper incisor absorbed horizontally to the apex. And the patients showed Angle II° malocclusion with II° overbite in anterior teeth and maxillary protrusion. A diagnosis of aggressive periodontitis and Angle II° malocclusion was made. The treatment of this patient lasts for 5 years which include periodontal initial therapy, orthodontic therapy, guided tissue regeneration (GTR) of right upper incisor and supportive periodontal therapy and the clinical result is fine. A hopeless upper incisor was successfully retained and the longtime clinical condition was stable. The strategy of retention of hopeless upper anterior teeth, the relationship of periodontal treatment and orthodontic treatment, and the indications of periodontal and orthodontic combined therapy were also discussed on the basis of this case. Generally, the positive factors in retention of hopeless teeth includes young age, absence of systemic conditions, strong motivation for maintaining the tooth, single root anatomy, integrated dentition, good response to cause-related therapy, intrabony alveolar bone defect, thick periodontal biotype, and regular supportive periodontal therapy. And in the progress of orthodontic therapy, regular supportive periodontal therapy and good plaque control is extremely important.

Abstract
Objective: To estimate the serotype and age-specific hospitalization burden associated with hand, foot and mouth disease (HFMD) in Anhua county of Hunan province, between October 2013 and September 2016. Methods: We collected hospitalization records of HFMD patients from 6 virological surveillance hospitals, and reimbursement records through new rural cooperative medical system from 23 township health centers to estimate the age-specific hospitalization burden of HFMD in Anhua. Combined with the results of virological surveillance, the serotype-specific hospitalization burden of HFMD in Anhua, was estimated. Results: During the three years, it was estimated that 3 541 clinical diagnosed HFMD cases, including 3 146 laboratory-confirmed HFMD cases, were hospitalized in Anhua, but only one was diaguosed as being severe. The estimated average hospitalization rate was 723/100 000(95%CI: 699/100 000-747/100 000) for clinical diagnosed HFMD and 642/100 000 (95%CI: 620/100 000-665/100 000) for laboratory-confirmed HFMD between October 2013 and September 2016. The cases caused by Cox A16 (208/100 000) and Cox A6 (202/100 000) had higher hospitalization rates compared with the cases caused by EV71 (130/100 000), Cox A10 (38/100 000) and other enterovirus (64/100 000), and the difference was statistically significant (P<0.001). HFMD-associated hospitalization rates peaked in children aged 1 year (3 845/100 000), and then decreased with age. Compared with the hospitalized HFMD caused by EV71 and Cox A16, Cox A6-associated hospitalizations mainly occurred in younger age groups (P<0.001). Conclusion: Our study revealed a substantial hospitalization burden associated with mild HFMD caused by EV71, Cox A16, Cox A6 and Cox A10, especially in young children, in Anhua.

Abstract
Objective: To investigate the roles and anti-cancer mechanism of artificially synthesized EGF-containing fibulin-like extracellular matrix protein (EFEMP1) derived tumor suppressor ZR30 protein in glioma (GBM). Methods: ZR30 protein were in vitro expressed using a wheat germ cell-free system. GBM cell lines (U251, U251NS, and U87) were cultured for 2-3 days in the presence or absence of ZR30 treatment. MMP-2 level was detected by gelatin zymography assay, moreover, the expression of EGFR, Notch-1 and p-Akt/Akt levels were determined by western blot. Additionally, MTT assay was used to measure ZR30's effect on the cell proliferation of U251 and U251NS cells. Furthermore, pre-mixed U251-GFP and U251NS-RFP cells (1∶9) were injected into the brain of nude mice, and then ZR30 or PBS was injected into the intra-tumor after 10 and 21 days, respectively. Then DNA was extracted from the right brain of nude mice in each group. Comparative quantitative polymerase chain reaction (CQ-PCR) was used to examine the copy numbers of human gene hSPAG16, mouse gene mSpag16, GFP and RFP. The survival status of each group of nude mice was also observed. Results: The levels of activated MMP-2 in U87 and U251 cells were lower after 10, 50 and 100 ng/ml ZR30 treatment for 2-3 days. Western blot analysis showed that ZR30 treatment reduced the expression of EGFR, Notch-1 and p-Akt/Akt in U251 cells, and inhibited Notch-1 and p-Akt/Akt expression in U251NS cells, and then decreased the response of U251 cells to EGF stimulation. Moreover, ZR30 inhibited the cell proliferation of U251 and U251NS two days after exposure. The in vivo orthotopic GBM xenografts were successfully constructed. CQ-PCR results indicated that the hSPAG16/mSpag16 ratios of mice in PBS group and ZR30 treatment groups at 180, 700, and 1 800 ng dosages were 3.67±2.82, 1.18±0.97, 1.75±1.55 and 1.38±1.17, respectively, and ZR30 treatment groups showed significantly lower ratios than the PBS group (P<0.05 for all). Correspondingly, the ratios of GFP/RFP in each group were 1.97±0.80, 1.97±0.85, 1.48±0.71 and 1.73±0.77, respectively, showing no statistical significance (P>0.05 for all). When treatment was performed 10 d after cell implantation, and the median survival time of mice in PBS group and ZR30 group was 40.5 days and 59.0 days, respectively. When treatment was performed 21 d after cell implantation, the median survival time of mice in PBS group and ZR30 group was extended to 57.0 days and 74.5 days, respectively. The median survival time of ZR30 treatment groups significantly prolonged (P<0.05 for all). Conclusions: ZR30 inhibits in vitro cell growth, invasion, angiogenesis and stemness maintenance in glioma via suppressing activated MMP-2, EGFR, p-Akt/Akt and Notch-1 proteins. In vivo, ZR30 markedly increased survival of mice harboring glioma xenografts, even for only one intra-tumoral injection at the time of early tumor formation. Overall, the in vivo and in vitro experiments supported the therapeutic potential of ZR30 for GBM.

Abstract
Objective: To investigate the antimicrobial susceptibility of Brucella and to provide a scientific basis for rational drug use and effective treatment of patients with brucellosis. Methods: A total of 41 Brucella strains were isolated from the blood of patients with brucellosis in 5 counties and 2 districts in Yuxi City, China from 2014 to 2016. The susceptibility to 23 antimicrobial drugs was tested using Kirby-Bauer (K-B) disk diffusion method and the sizes of antimicrobial rings were recorded. The susceptibility testing results were interpreted according to the Drug Susceptibility Testing Guideline (2009 version) . Results: The susceptibility rate of Brucella was 100.00% to ofloxacin, ciprofloxacin, levofloxacin, and amikacin and >90% to cefotaxime, cefepime, imipenem, doxycycline, cefoperazone, minocycline, tobramycin, rifampicin, cefoperazone/sulbactam, and chloramphenicol. The high resistance to aztreonam and ampicillin was observed (87.80% and 41.46%). Doxycycline-intermediate strains, rifampicin-intermediate strains, and rifampicin-resistant strains were identified. Conclusion: Doxycycline and rifampicin are commonly used in the treatment of brucellosis, but doxycycline/rifampicin-intermediate and-resistant strains have been identified. The susceptibility of Brucella to fluoroquinolones and cephalosporins was high, so the two drugs can be considered in the treatment of brucellosis.

Abstract
BACKGROUND Whether preoperative bodyweight is associated with long-term prognosis in patients after liver resection for hepatocellular carcinoma (HCC) is controversial. This study aimed to investigate the relationship of patient weight with long-term recurrence and overall survival (OS) after curative liver resection for HCC. METHODS Data for patients with HCC who underwent curative liver resection between 2000 and 2015 in five centres in China were analysed retrospectively in three groups according to their preoperative BMI: underweight (BMI 18·4 kg/m2 or less), normal weight (BMI 18·5-24·9 kg/m2 ) and overweight (BMI 25·0 kg/m2 or above). Patients' baseline characteristics, operative variables and long-term survival outcomes were compared. Univariable and multivariable Cox regression analyses were performed to identify risk factors for OS and recurrence-free survival (RFS) after resection. RESULTS Of 1524 patients, 107 (7·0 per cent) were underweight, 891 (58·5 per cent) were of normal weight and 526 (34·5 per cent) were overweight. Univariable analyses showed that underweight and overweight patients had poorer OS (both P < 0·001) and RFS (both P < 0·001) than patients of normal weight. Multivariable Cox regression analysis also identified both underweight and overweight to be independent risk factors for OS (hazard ratio (HR) 1·22, 95 per cent c.i. 1·19 to 1·56, P = 0·019; and HR 1·57, 1·36 to 1·81, P < 0·001, respectively) and RFS (HR 1·28, 1·16 to 1·53, P = 0·028; and HR 1·34, 1·17 to 1·54, P < 0·001). CONCLUSION Underweight and overweight patients appear to have a worse prognosis than those of normal weight following liver resection for HCC.

Abstract
OBJECTIVE To use the cone-beam computed tomography (CBCT) to evaluate the three-dimensional (3D) changes of maxillary landmarks in the maxillary protraction with alternating rapid palatal expansion and constriction and with rapid palatal expansion, and to provide some clinical suggestions for the early treatment of Class III malocclusion. METHODS A total of 36 maxillary retrusive patients were included and randomized in a 1:1 ratio to either the intervention group (alternating rapid palatal expansion and constriction group, RPE/C) or the control group (rapid palatal expansion group, RPE). Randomization was accomplished with permuted block randomization based on participation sequence. The patients in the RPE/C were treated for 10 weeks (0.5 mm/d) with the repetition of two-week palatal expansion and two-week palatal constriction. The patients in the RPE were taught to complete rapid palatal expansion for 2 weeks (0.5 mm/d ). The patients were instructed to come to the office for the follow-up to ensure the correct procedures. Damaged expanders were repaired (or replaced) and rebanded quickly. Sequential CBCT images including pretreatment (T1), post-expansion (T2) and post-protraction (T3) were required for 3D reconstruction, establishment of landmarks, measurement and analysis by Mimics 10.01. RESULTS There was significant forward movement of subspinale (A) in the RPE/C after the treatment with (3.06±1.29) mm, compared with RPE (2.16±1.27) mm, P<0.05. There were more symmetrical changes of the landmarks in the RPE/C and there was no statistic significance of the entire treatment time between the two groups. Moreover, the maxillary skeletal landmarks had the following 3D changes of a forward and downward movement during the expansion stages T2-T1, a forward and upward movement during the protraction stages T3-T2 and a forward and downward movement during the total treatments T3-T1 compared with the control group. And the width between the bilateral landmarks increased during the expansion stages T2-T1, narrowed down during the protraction stages T3-T2 and increased during the total treatments T3-T1. CONCLUSION The maxillary protraction with alternating rapid palatal expansion and constriction provided clinical benefits on maxillary advancement and symmetrical changes in the orthopedic treatment of the patients with maxillary retrognathism and it required further study on the orthodontic analysis and measurements of CBCT.

Abstract
In this study, an orthogonal array design with 16 factors at two levels (216) was performed to develop an artificial diet rearing the adults of seven spotted ladybird beetle Coccinella septempunctata. The parameters of weight gain and survival rate of adults, preoviposition period, fecundity and hatching rate of diet-fed adults were monitored. The 16 factors were included: pork liver, infant formula, sucrose, olive oil, yolk, corn oil, yeast powder, cholesterol, casein, casein hydrolysate, vitamin powder, 65% juvenile hormone III, protein powder, vitamin E, honey and pumpkin. Results indicated that pork liver, sucrose, yolk, yeast powder, juvenile hormone, pumpkin and honey were the main ingredients of the artificial diet contributing to weight gain and survival rate of adults, preoviposition period, fecundity and hatching rate. A follow-up fed with a selection of improved formulas confirmed the validity of the optimization as predicted by the orthogonal array analysis, indicating the usefulness of this method for selecting artificial diets for C. septempunctata. The weight gain and fecundity of adults reared on the improved artificial diet were 87.46 and 62.70% of those reared on Aphis craccivora; the survival rate and hatch rate were similar between the diet-fed and aphid-fed, while the preoviposition period was significantly shorter for C. septempunctata fed on the diet than on A. craccivora. The latter formula was superior to any formerly developed formulas and may thus have potential for the improved artificial diet mass rearing of C. septempunctata.

Abstract
Background: Localized macular edema and retinal nerve fiber layer (RNFL) thinning have been reported shortly after laser in situ keratomileusis (LASIK) in adults. However, it is still unclear how LASIK affects the retina of children. This study aimed to investigate the macular retina and RNFL thickness in children with refractive amblyopia who underwent femtosecond laser-assisted LASIK (FS-LASIK). Methods: In this study, we included 56 eyes of 32 patients with refractive amblyopia who underwent FS-LASIK in our hospital from January 2012 to December 2016. Foveal (foveal center retinal, parafoveal retinal, and perifoveal), macular inner retinal (superior and inferior), and peripapillary RNFL thicknesses (superior, inferior, temporal, and nasal) were measured using Fourier-domain optical coherence tomography before surgery and 1 day, 3 days, and 1 week after surgery. We divided these patients into three groups based on their refractive error: High myopic group with 22 eyes (equivalent sphere, >6.00 D), mild myopic group with 19 eyes (equivalent sphere, 0–6.00 D), and hyperopic group with 15 eyes (equivalent sphere, >+0.50 D). We compared the macular retina and RNFL thickness before and after LASIK. A paired simple t-test was used for data analysis. Results: One week after surgery, the visual acuity for all 56 eyes of the 32 patients reached their preoperative best-corrected vision. Visual acuity improved two lines or better for 31% of the patients. The residual refractive errors in 89% of the patients were within ±0.5 D. In the high myopic group, the foveal center retinal and parafoveal retinal thicknesses were thicker 1 day and 3 days after surgery than before surgery (t = 2.689, P = 0.012; t = 2.383, P = 0.018, respectively); no significant difference was found 1 week after surgery (P > 0.05). The foveal center retinal and parafoveal retinal thicknesses were greater 1 day after surgery than they were before surgery (P = 0.000 and P = 0.005, respectively) in the mild myopic and hyperopic groups. No significant difference was found 3 days or 1 week after surgery (P > 0.05). In all three groups, no significant difference was found in the macular inner retinal or peripapillary RNFL thickness 1 day, 3 days, or 1 week after surgery (P > 0.05). Conclusions: The foveal center retinal edema after FS-LASIK is mild and reversible in children, that mostly occurred in the high myopic group with no effect on the visual acuity, and is always relieved within 1 week.

Abstract
OBJECTIVE To retrospectively evaluate clinical and radiographic records of chronic periodontitis patients who underwent extraction-orthodontic treatment, in order to determine the effect of the treatment on probing depth, alveolar bone height of teeth adjacent to the extraction sites. METHODS In the study, 33 chronic periodontitis patients who had finished extraction-orthodontic treatment were selected, the periodontal examination system tables and panoramic tomography were recorded before treatment (T0) and after treatment (T1), and the periodontal probing depth (PD), residual alveolar bone height (RBH) of the teeth adjacent to extraction sites (TAES) and the non-teeth adjacent to extraction sites (NTAES) were measured at T0 and T1. RESULTS There was insignificant difference in PD of TAES and NTAES at T0 [(2.40±0.51) mm vs. (2.42±0.55) mm,P>0.05], neither was that at T1 [(2.70±0.67) mm vs. (2.67±0.64) mm, P>0.05]; From T0 to T1, PD of TAES and NTAES had mean increases of 0.3 mm [(2.40±0.51) mm vs. (2.70±0.67) mm,P<0.01] and 0.25 mm [(2.42±0.55 mm vs. (2.67±0.64) mm, P<0.01], respectively. And PD of TAES and NTAES increased from T0 to T1 statistically in the same degree [(0.30±0.64) mm vs. (0.25±0.58) mm,P>0.05]; at T0, RBH of TAES was 0.024 smaller than that of NTAES (0.74±0.16 vs. 0.76±0.16,P<0.05), but there was no difference in RBH between the TAES and NTAES at T1 (0.78±0.14 vs. 0.79±0.12,P>0.05); From T0 to T1, RBH of TAES and NTAES had mean increases of 0.04 (0.74±0.16 vs.0.78±0.14,P<0.05) and 0.02 (0.76±0.16 vs. 0.79±0.12,P<0.05), respectively. And the change of RBH between TAES and NTAES from T0 to T1 had no statistical difference (0.04±0.11 vs. 0.02±0.08,P>0.05)RBH of TAES in the side close to extraction sites was as the same as that of TAES in the side away from the extraction sites at T0 (0.73±0.17 vs. 0.74±0.16,P>0.05). From T0 to T1, RBH of both sides of TAES had mean increases of 0.04 (0.73±0.11 vs. 0.77±0.11,P<0.05) and 0.04 (0.74±0.11 vs. 0.78±0.11,P<0.05), respectively. But for both sides of TAES, from T0 to T1, there was no significant difference in change of RBH (0.04±0.11 vs. 0.04±0.11,P>0.05). CONCLUSIONS With strict control of periodontal inflammation and maintenance of oral hygiene, orthodontic treatment preserves the periodontal conditions in patients with chronic periodontitis, and the extraction-orthodontic treatment can preserve the bone height of the teeth adjacent to extraction sites.

Abstract
Objective: To investigate the association between the value of α-thalassemia minor and the outcomes in pregnant women. Methods: A total of 445 pregnant women with α-thalassemia minor were selected as thalassemia group in the Pingguo County Maternal and Child Health Hospital of Guangxi from January 2011 to December 2015, with ratio of 1∶4 healthy pregnant women was randomly recruited as non-thalassemia group. Clinical characteristics and pregnancy outcomes of the two groups were retrospectively analyzed using methods including t test, χ(2) test, and logistic regression model and ROC curve. Results: There were no significant differences noticed in factors as age, BMI, gestational age and educational level of the two groups. Hemoglobin of the thalassemia group was significantly lower than that of the non-thalassemia group (P<0.001). Differences on parity, ethnicities or occupation were statistically significant. Results from univariate analysis showed that the proportions of low birth weight, small for date infant and 1 min Apgar score<7 were higher in the thalassemia group, but the ratio of adverse pregnancy outcomes was comparable on parameters as preterm birth, stillbirth, macrosomia. Findings from the unconditional logistic regression showed that pregnancy complicated with α-thalassemia minor appeared a risk for both newborns with low birth weight (aOR=2.29, 95%CI: 1.32-3.95) and small for date infant (aOR= 2.11, 95%CI: 1.16-3.84). The ROC curve showed that α-thalassemia minor combined with multiple indicators presented a certain predictive value on neonatal birth weight. Conclusion: Pregnancy complicated with α-thalassemia minor was likely to increase the risk of birth weight loss in newborns, suggesting that prenatal care for pregnant women with thalassemia be strengthened, in order to reduce the incidence of adverse pregnancy outcomes.

Abstract
OBJECTIVE To investigate the effects of Toll like receptors on the osteogenesis of human pe-riodontal ligament stem cells (hPDLSCs) and probable molecular mechanism. METHODS Real-time PCR and flow cytometry were applied to test the expression of TLRs in hPDLSCs and the positive cell percentage of TLR. hPDLSCs were cultured in osteogenic medium for 7 to 14 days with different TLR agonists at various concentrations . The effect of different TLR on osteogenic differentiation of hPDLSCs was evaluated by alizarin red S staining, alkaline phosphatase (ALP) staining and ALP activity assay. Western blotting was used to analyze the phosphorylation levels of extracellular regulated protein kinases (ERK), c-Jun N-terminal protein kinase (JNK), P38, AKT and expression of Runx2 an osteogenic related gene after treatment with TLR agonists, compared with the effect of inhibitors of mitogen activated protein kinase (MAPK) or protein kinase B (PKB or AKT) on Runx2 expression of hPDLSCs cultured in osteogenic medium. RESULTS Higher expressions of TLR1,3,4,6 were found in hPDLSCs through real-time PCR. Positive cell percentage of TLR was determined by flow cytometry and described as TLR1: 2.82%±0.68%; TLR2: 1.26%±0.09%; TLR3: 13.23%±2.05%; TLR4: 3.64%±0.79%; TLR6: 3.21%±1.64%, whose tendency was comparable to their mRNA expression in hPDLSCs. Most TLR ligands had no effect on the ALP staining, activity and mineralization of hPDLSCs at lower concentration except for 0.1 mg/L PolyI:C could induce the osteogenic ability of hPDLSCs. On the contrary, Higher concentration of TLR ligands (PolyI:C: 10 mg/L, LPS: 10 mg/L , Pam3CSK4: 1 mg/L, FSL-1: 50 μg/L) had obviously inhibitory effect on osteogenic differentiation of hPDLSCs. Activation of TLR using higher concentration of TLR ligands could downregulate the phosphorylation levels of ERK, P38, JNK and AKT, and also reduced the expression of Runx2, compared with the untreated control. The inhibitors of MAPK (U0126, SP600125,SB203580) and inhibitor of AKT (perifosine) could also inhibit Runx2 expression. CONCLUSION Higher concentration of TLR ligands could inhibit osteogenic differentiation of hPDLSCs. This inhibitory effect seemed to be related to decreased phosphorylation of MAPK and AKT.

Abstract
OBJECTIVE To analyze the stress distribution in the periodontal ligament (PDL) under different loading conditions at the stage of space closure by 3D finite element model of customized lingual appliances. METHODS The 3D finite element model was used in ANSYS 11.0 to analyze the stress distribution in the PDL under the following loading conditions: (1) buccal sliding mechanics (0.75 N,1.00 N,1.50 N), (2) palatal sliding mechanics (0.75 N,1.00 N,1.50 N), (3) palatal-buccal combined sliding mechanics (buccal 1.00 N + palatal 0.50 N, buccal 0.75 N + palatal 0.75 N, buccal 0.50 N+ palatal 1.00 N). The maximum principal stress, minimum principal stress and von Mises stress were evaluated. RESULTS (1) buccal sliding mechanics(0.75 N,1.00 N,1.50 N): maximum principal stress: at the initial of loading, maximum principal stress, which was the compressed stress, distributed in labial PDL of cervix of lateral incisor, and palatal distal PDL of cervix of canine. With increasing loa-ding, the magnitude and range of the stress was increased. Minimum principal stress: at the initial of loading, minimum principal stress which was tonsil stress, distributed in palatal PDL of cervix of lateral incisor and mesial PDL of cervix of canine. With increasing loading, the magnitude and range of minimum principal stress was increased. The area of minimum principal stress appeared in distal and mesial PDL of cervix of central incisor. von Mises stress:it distributed in labial and palatal PDL of cervix of lateral incisor and distal PDL of cervix of canine initially. With increasing loading, the magnitude and range of stress was increased towards the direction of root. Finally, there was stress concentration area at mesial PDL of cervix of canine. (2) palatal sliding mechanics(0.75 N,1.00 N,1.50 N): maximum principal stress: at the initial of loading, maximum principal stress which was the compressed stress, distributed in palatal and distal PDL of cervix of canine, and distal-buccal and palatal PDL of cervix of lateral incisor. With increasing loading, the magnitude and range of the stress was increased. Minimum principal stress: at the initial of loading, minimum principal stress which was tonsil stress, distributed in distal-interproximal PDL of cervix of lateral incisor and mesial-interproximal PDL of cervix of canine. With increasing loading, the magnitude and range of the stress was increased.von Mises stress: von Mises stress distributed in palatal and interproximal PDL of cervix of canine. With increasing loading, the magnitude and range of stress was increased. Finally, von Mises stress distributing area appeared at distal-palatal PDL of cervix of canine. (3) palatal-buccal combined sliding mechanics: maximum principal stress: maximum principal stress still distributed in distal-palatal PDL of cervix of canine. Minimum principal stress: minimum principal stress distributed in palatal PDL of cervix of lateral incisor when buccal force was more than palatal force. As palatal force increased, the stress concentrating area transferred to mesial PDL of cervix of canine.von Mises stress: it was lower and more well-distributed in palatal-buccal combined sliding mechanics than palatal or buccal sliding mechanics. CONCLUSION Using buccal sliding mechanics,stress majorly distributed in PDL of lateral incisor and canine, and magnitude and range of stress increased with the increase of loading; Using palatal sliding mechanics, stress majorly distributed in PDL of canine, and magnitude and range of stress increased with the increase of loading; With palatal-buccal combined sliding mechanics, the maximum principal stress distributed in the distal PDL of canine. Minimum principal stress distributed in palatal PDL of cervix of lateral incisor when buccal force was more than palatal force. As palatal force was increasing, the minimum principal stress distributing area shifted to mesial PDL of cervix of canine. When using 1.00 N buccal force and 0.50 N palatal force, the von Mises stress distributed uniformly in PDL and minimal stress appeared.
