Abstract
COVID-19 has been prevalent in Wuhan and spread rapidly to all of our country. Some cases can develop into ARDS, or even death. We will share the treatment experience of severe COVID-19 with the first-line treatment experience. The best respiratory support mode should be selected, but the timing of intubation and protection during intubation are two difficulties; patients with high level peep and poor effect in prone position can be given ECMO support. For COVID-19 patients with mechanical ventilation, reasonable sedation and analgesia strategies should be formulated; delirium should not be ignored. In addition, there is up regulation of inflammatory factors in patients with severe COVID-19, but the effect of renal replacement therapy needs to be further confirmed by clinical research.

Abstract
Objective: To explore the value of nucleic acid detection methods in pharyngeal swabs in the etiological diagnosis of Mycoplasma pneumoniae (MP) infection in children. Methods: Four hundred and fifty-four (male 210, female 244) children with pneumonia in Department of Pulmonology, Children's Hospital of Zhejiang University School of Medicine were enrolled from July, 2018 to October, 2018. Pharyngeal swabs and venous blood were obtained on the first or the second day after hospitalization. Fluorescence detection quantitative amplification of DNA, thermostatic amplification of RNA, MP culture and MP-IgM were used to detect MP simultaneously. MP infection is diagnosed if MP culture is positive or the two of the other three methods are positive. Pharyngeal swabs were acquired and detected using fluorescence quantitative amplification of DNA, thermostatic amplification of RNA and MP culture again for children with confirmed MP infection before discharge. The detection rates and quantitative changes of the three methods were compared, and χ(2) test was used for comparison among groups. Results: A total of 454 hospitalized children with pneumonia were included in this study. The detection rates of fluorescence quantitative amplification of DNA, thermostatic amplification of RNA, MP culture and MP-IgM IgM were 43.6% (198/454), 43.2% (196/454), 40.0% (180/454) and 30.6% (139/454) respectively. The difference of detection rates of the four methods was statistically significant (χ(2)=20.8, P<0.05),but no significant difference between the detection rates of fluorescence quantitative amplification of DNA and thermostatic amplification of RNA was found (χ(2)=0.018, P=0.900). They both had higher detection rates than MP-IgM or MP culture. MP infection is diagnosed if MP culture is positive or the two of the other three methods are positive, and two hundred and nine children were diagnosed as MP infection. In the second test of MP infection in 209 children before discharge, the positive rate of MP culture was 67.5% (141/209), with 39.4% (13/33) changed from negative to positive, and 27.3% (48/176) changed from positive to negative. The positive rate of thermostatic amplification of RNA was 82.3% (172/209), with 16.2% (31/191) turned from positive to negative, and 66.7% (12/18) turned from negative to positive. The positive rate of fluorescence quantitative amplification of DNA was 67.0% (140/209), with 52.9% (18/34) cases changed from negative to positive, and 30.3% (53/175) cases changed from positive to negative. MP-DNA load decreased in 141 cases (67.5%) and increased in 68 cases (32.5%) in the second test among the positive samples tested by fluorescence quantitative amplification of DNA. The detection rates of the four methods in the non-severe group and the severe group were similar, and the differences among the groups were not statistically significant (all P>0.05). In the second test, the proportion of changing from negative to positive in the severe group was higher than that in the non-severe group, but only the difference in the thermostatic amplification of RNA was statistically significant (P=0.038) and the cases of changing from negative to positive of thermostatic amplification of RNA in the severe group and non-severe group are 7 and 5 respectively. Conclusions: The methods of pharyngeal swab nucleic acid detection have high sensitivity and application value in the etiological diagnosis of acute MP infection in children. The results of fluorescence quantitative amplification of DNA and thermostatic amplification of RNA are highly consistent, and they are both more advantageous than MP-IgM. Repeated testing in the acute phase is helpful to find MP infection children whose first test is negative. The load of MP-DNA did not decrease in some children in the acute stage after antibiotic treatment.

Abstract
The treatment of critically ill patients with coronavirus disease 2019(COVID-19) faces compelling challenges. In this issue, we'd like to share our first-line treatment experience in treating COVID-19. Hemodynamics need be closely monitored and different types of shock should be distinguished. Vasoconstrictor drugs should be used rationally and alerting of complications is of the same importance. The risk of venous thromboembolism (VTE) needs to be assessed, and effective prevention should be carried out for high-risk patients. It is necessary to consider the possibility of pulmonary thromboembolism (PTE) in patients with sudden onset of oxygenation deterioration, respiratory distress, reduced blood pressure. However, comprehensive analysis of disease state should be taken into the interpretation of abnormally elevated D-Dimer. Nutritional support is the basis of treatment. It's important to establish individual therapy regimens and to evaluate, monitor and adjust dynamically. Under the current epidemic situation, convalescent plasma can only be used empirically, indications need to be strictly screened, the blood transfusion process should be closely monitored and the curative effect should be dynamically evaluated.

Abstract
Objective: Under different diagnostic scenarios, we tried to establish a tuberculosis dynamic model, to predict the incidence burden and to provide evidence for developing the prevention and control programs of tuberculosis. Methods: A systematic dynamic model was established to fit the annual incidence rates of tuberculosis data from the China CDC, between 2005 and 2018. Basic reproductive number (R(0)) was calculated. Impact of different diagnostic scenarios on tuberculosis burden was explored by numerical changes in diagnosis-related parameters. Results: Results from the Chi-square test indicated that the model accuracy appeared as: χ(2)=1.102 (P=1.000). Also, the computed result showed that R(0)=0.063<1, indicating that tuberculosis would gradually be disappearing in China. Approaches that including 'reducing the delayed diagnosis time'or 'improving the timely medical treatment'would end the fluctuations of the number of infectious and hospitalized patients and thus leading to continuous reduction in the number of these patients, in a long run. Conclusions: This model fitted well for the trend of tuberculosis incidence rates between 2005 and 2018. Reducing the delay time in diagnosis and improving the rate of timely medical treatment could effectively reduce the long-term burden of tuberculosis. Improvement of this model would be further explored.

Abstract
The new coronavirus pneumonia (NCP), also named as COVID-19 by WHO on Feb 11 2020, is now causing a severe public health emergency in China since. The number of diagnosed cases is more than 40,000 until the submission of this manuscript. Coronavirus has caused several epidemic situations world widely, but the present contagious disease caused by 2019 new coronavirus is unprecedentedly fulminating. The published cohorts of 2019 new coronavirus (n-Cov) are single-center studies, or retrospective studies. We here share the therapeutic experiences of NCP treatment with literature review. Combination of Ribavirin and interferon-α is recommended by the 5(th) edition National Health Commission's Regimen (Revised Edition) because of the effect on Middle East respiratory syndrome (MERS), and the effectiveness of Lopinavir/Ritonavir and Remdisivir needs to be confirmed by randomized controlled trial (RCT), given the situation of no specific antivirus drug on NCP is unavailable. Systemic glucocorticosteroid is recommended as a short term use (1~2 mg·kg(-1)·d(-1), 3~5 d) by the 5(th) edition National Health Commission's Regimen (Revised Edition) yet RCTs are expected to confirm the effectiveness. Inappropriate application of antibiotics should be avoided, especially the combination of broad-spectrum antibiotics, for the NCP is not often complicated with bacterial infection.

Abstract
SummaryThe necks of two young patient can't moved around the plane after tonsillectomy. CT of atlantoaxial bone showed that the anatomy of atlantoaxial joint had been turned upside down. It is an extremely rare entity and very few have been reported in the literature. The reasons and specific mechanisms of atlantoaxial dislocation are the result of the aspects of anatomy of atlantoaxial joint and surrounding structures, biomechanics and histology. The patients have been cured by the raise neck as pinned and gived Anti-inflammatory. Atlantoaxial dislocation is difficult to be distinguish in the complication. It may lead to serious consequences in sometimes. When the event occurs medical staff has to take effect way to treat immediately. This point should be considered by medical staff.

Abstract
OBJECTIVES Embryonic numerical and structural chromosomal abnormalities are the most common cause of early pregnancy loss. However, the role of submicroscopic copy-number variations (CNVs) in early pregnancy loss is unclear, and little is known about the critical regions and candidate genes for miscarriage, because of the large size of structural chromosomal abnormalities. The aim of this study was to identify potential miscarriage-associated submicroscopic CNVs and critical regions of large CNVs as well as candidate genes for miscarriage. METHODS Over a 5-year period, 5180 fresh miscarriage specimens were investigated using quantitative fluorescent polymerase chain reaction/CNV sequencing or chromosomal microarray analysis. Statistically significant submicroscopic CNVs were identified by comparing the frequency of recurrent submicroscopic CNVs between cases and a published control cohort. Furthermore, genes within critical regions of miscarriage-associated CNVs were prioritized by integrating the Residual Variation Intolerance Score and the human gene expression dataset for identification of potential miscarriage candidate genes. RESULTS Results without significant maternal-cell contamination were obtained in 5003 of the 5180 (96.6%) cases. Clinically significant chromosomal abnormalities were identified in 59.1% (2955/5003) of these cases. Three recurrent submicroscopic CNVs (microdeletions in 22q11.21, 2q37.3 and 9p24.3p24.2) were significantly more frequent in miscarriage cases, and were considered to be associated with miscarriage. Moreover, 44 critical regions of large CNVs were observed, including 14 deletions and 30 duplications. There were 309 genes identified as potential miscarriage candidate genes through gene-prioritization analysis. CONCLUSIONS We identified potential miscarriage candidate CNVs and genes. These data demonstrate the importance of CNVs in the etiology of miscarriage and highlight the importance of ongoing analysis of CNVs in the study of miscarriage. Copyright © 2019 ISUOG.

Abstract
OBJECTIVE To understand the situation of Schistosoma japonicum infections in wild animals in transmission-controlled schistosomiasis-endemic areas in Jiangxi Province, so as to provide scientific evidence for implementing precision control interventions and achieving the goal of transmission interruption and elimination of schistosomiasis. METHODS Five endemic villages from Ruichang City and Pengze County that were heavily endemic for schistosomiasis in Jiangxi Province, were selected as the study villages. Wild animals like wild mice were captured, and the livers of wild animals were purchased from the snail habitats in the study villages for detection of S. japonicum infections. In the study villages, S. japonicum human infections were screened using indirect hemagglutination assay (IHA) followed by parasitological examinations with miracidial hatching test and Kato-Katz method, and the S. japonicum infection in livestock was tested using a miracidial hatching test with a plastic tube. In addition, snail survey was conducted in the study villages by means of systematic sampling combined with environmental sampling, and the S. japonicum infection in snails was detected using a loop-mediated isothermal amplification (LAMP) assay. RESULTS A total of 240 liver specimens were sampled or purchased from 5 species of wild animals in the study villages, including wild mice, weasels, pigs, deer and rabbits. A total of 172 wild mice were captured, with a 2.91% rate of S. japonicum infection, and there was no S. japonicum infection detected in other wild animals. The prevalence of Capillaria hepatica infection was 12.21%, 1.96% and 12.50% in wild mice, deer and pigs, respectively. In addition, there was no S. japonicum infection found in either humans or livestock in the study villages, and the mean snail density varied from 0.13 to 0.80 snails/0.1 m2 in the study villages. LAMP assay detected S. japonicum infection in 2 tubes in a study village. CONCLUSIONS The role of wild animals in schistosomiasis transmission and their potential risks can not be neglected in hilly schistosomiasis-endemic areas of Jiangsu Province after transmission control. Intensified surveillance and targeted control measures should be implemented to consolidate schistosomiasis control achievements.

Abstract
Objective: To study the imaging characteristics and accumulate data of optical coherence tomography (OCT) of the lacrimal punctum in normal adults. Methods: From September to November 2018, 59 healthy adults (90 eyes) with normal lacrimal punctum structure were enrolled in this cross-sectional study conducted at the Lacrimal Center of Ophthalmology, Third Medical Center of PLA General Hospital, including 21 males (34 eyes) and 38 females (56 eyes), aged 18-65 years. All the subjects were examined by slit lamp microscopy to measure the maximum transverse diameter. OCT was performed to observe the inferior lacrimal punctum, including the external punctal diameter, the punctal diameter at 100 μm and 200 μm depth. The difference in the diameter of different parts of the punctum was analyzed. Independent sample t test and single factor analysis of variance were used for statistical analysis. Results: In normal adults, the maximum transverse diameter under a slit lamp was (545.6±149.3) μm, the external punctal diameter on OCT images was (548.4±130.5) μm, and the punctal width at 100 μm and 200 μm depth on OCT images was (262.8±120.8) μm and (179.2±110.0) μm, respectively. There was no significant difference between the maximum transverse diameter of the punctum under a slit lamp microscope and the OCT outer diameter of the punctum (t=0.133, P=0.894). There were significant differences between the diameter of the lacrimal punctum in the different scanning sites of the OCT (F=213.237, P<0.01). There was significant difference between the punctal width at 100 μm and the external punctal diameter on OCT images (t=15.229, P<0.01). There was significant difference between the punctal width at 200 μm and the external punctal diameter on OCT images (t=20.517, P<0.01). There was significant difference between the punctal width at 100 μm and 200 μm depth on OCT images (t=4.855, P<0.01). Conclusion: The width of different parts of the lacrimal punctum in healthy adults is different on OCT images, and the punctal width at 200 μm depth is the narrowest.

Abstract
Abstract
Background
Arterial stiffness has been implicated in pathophysiology of heart failure (HF) since it is involved in the ventricular-vascular coupling. Recently, new indices obtained by a cuff oscillometric technique, the arterial velocity-pulse index (AVI) for the stiffness of central arteries and the arterial pressure-volume index (API) for the stiffness of peripheral arteries have been developed and validated. However, the AVI and API measurement has not been attempted in HF population.
Purpose
This study aimed to investigate the relationship between the AVI, API and clinical outcomes in HF patients.
Methods
A prospective cohort of patients with acute decompensated HF were enrolled within 6 months, who were admitted to a tertiary referral hospital in China. Measurement of the AVI and API (AVE-1500, Shisei Datum, Tokyo, Japan) was performed on the day of admission and discharge. Patients were followed up to 6 months for the composite endpoint of all-cause death and HF rehospitalization.
Results
A Total of 127 patients were recruited for analysis (60±15 years, 70% male). 80% of the patients were in New York Heart Association (NYHA) Class III or above at admission, who presented a mean left ventricular ejection fraction (LVEF) of 34±9%. During hospitalization, all patients received guideline directed medical therapy if not contraindicated. The AVI (27.3±5.2 vs. 28.6±6.7, p=0.002) and API (24.9±4.9 vs. 26.0±6.5, p=0.05) were lower at discharge than at admission. By dividing the patients into tertiles according to the amino-terminal pro-brain natriuretic peptide (NT-proBNP), LVEF, transmitral E velocity over mitral annular e' velocity (E/e' ratio) and systolic blood pressure (SBP) at admission, it was observed that the AVI increased with a higher level of NT-proBNP (p for trend <0.001), a larger E/e' (p<0.001) and a lower LVEF (p=0.001), while the API increased as the SBP became higher (p=0.005).The improvement in AVI at discharge was correlated with that in LVEF (R=-0.3024, p<0.05) and NT-proBNP (R=0.3118, p<0.05), while the change in API was positively correlated with that in SBP (R=0.3897, p<0.001). In 6 months after discharge, there were 52 predefined events including 15 deaths and 44 HF rehospitalization. Apart from the level of NT-proBNP, the AVI at discharge of ≥26 showed a trend of being associated with the composite outcome (2.747, 1.411–5.349, p<0.001 for univariate analysis; 1.8648, 0.8928–3.8949, p=0.0973 for multivariate analysis).
Conclusions
New noninvasive arterial stiffness indices as the AVI and API reflected severity of illness and mid-term prognosis in admitted HF patients. Further studies are warranted for understanding its mechanisms and developing clinical applications.

Abstract
Background
Two-dimensional speckle-tracking echocardiography (2D-STE) for the measurement of circumferential ascending thoracic aortic strain (CAAS) in healthy adults is not elucidated. We aimed to establish normal adult STE-derived CAAS and to evaluate associations with age, gender and other physiologic parameters.
Methods
One hundred eighty-one healthy subjects aged 24–75 were prospectively gathered and examined with two-dimensional echocardiography. The global peak CAAS was the parameter used, and an average of six segments of arterial wall deformation was calculated. The corrected CAAS was calculated as the global CAAS/pulse pressure (PP). Aortic stiffness (β2) index was assessed according to ln(Ps/Pd)/CAAS.
Results
We included 171 healthy subjects (age 44.3±10.9 years, 50% female, CAAS16.0±6.9%). The CAAS was independently predicted by age (β=−0.387, P<0.001), and gender (β=−2.701, P=0.001). The corrected CAAS was independently predicted by age (β=−0.009, P<0.001), SAC (β=−0.206, P<0.001) and gender (β=−0.068, P=0.001). The β2 index was independently predicted by age (β=0.136, P<0.001), and PP (β=0.059, P=0.007).
Conclusion
CAAS using 2D-STE can be performed on a clinical basis and may become an important method for the assessment of aortic mechanical parameter. Age, gender and LV afterload-related variables were the most import determinants of 2D-STE global CAAS. Therefore, these factors should be taken into account for strain interpretation in clinical practice.

Abstract
Guillain-Barre syndrome (GBS) is an autoimmune disease on the injury of peripheral nerve myelin proteins or axon, of which the acute motor axonal neuropathy (AMAN) as a subtype is of infrequence and an extremely low incidence of post-operation. This article originally reported one case from Peking University People's Hospital on successful treatment of severe GBS (AMAN) on post-operation with renal carcinoma and meningioma. The diagnostic criteria of AMAN refer to AIDP, of which the feature of AMAN suggests a pure motor nerve dysfunction and significant damage on motor axon. It is reported that infection and surgery may induce GBS. The positive result of IgM and IgG was considered the application of ganglioside and blood-brain barrier might be damaged after meningioma surgery which eased the drug to enter the cerebrospinal fluid circulation and induced lesions, therefore the etiology on this GBS case was of high confidence of administrating ganglioside drugs. Autonomic nerve dysfunctions, such as blood pressure fluctuations and arrhythmia could be caused in GBS, of which about 3%-10% of GBS patients would die. Early use of gamma globulin or plasma exchange was recommended internationally, but recently some new ideas, to some extent, of significance on GBS treatment emerged. However, there was still no consensus on GBS treatment systematically all over the world. Till now, the general treatment program on GBS may be still gamma globulin or plasma exchange and a curious judgment of prognosis is essential in order to make a reasonable plan. That it was usually of no omen on severe autonomic nerve dysfunction must be successively monitored, the same as the management of the respiratory tract and nutrition support. The key measures taken on lung recruitment was postural drainage on this case with a low cost but a qualified effectiveness. This case report aimed to deepen the understanding of AMAN and acquaint the cutting-edge advances on the treatment of GBS, as well as providing successful treatment experience for the prevention on similar cases.

Abstract
OBJECTIVE Deep learning models, including recurrent neural network (RNN) and gated recurrent unit (GRU), were used to construct the clinical prognostic prediction models for peritoneal dialysis (PD) patients based on routine clinical data. The performance of the RNN and GRU were compared with logistic regression (LR), which is commonly used in medical researches. The possible underlining clinical implications based on the result from the GRU model were also investigated. METHODS We used the clinical data from the PD center of Peking University Third Hospital as the data source. Both the baseline data at the beginning of dialysis, and the follow-up and prognostic data of the patients were used by the RNN and GRU prediction models. The hyper-parameters were tuned based on the 10-fold cross-validation. The risk prediction performance of each model was evaluated via area under the receiver operation characteristic curve (AUROC), recall rate and F1-score on the testset. RESULTS A total of 656 patients with the 261 occurrences of death were included in the experiment. The total number of all diagnostic records were 13 091. The results on the testset showed that the AUROC of the LR model, RNN model, and GRU model was 0.701 4, 0.786 0, and 0.814 7, respectively. The predictive performances of the GRU and RNN models were significantly better than that of the LR model. The performances of the GRU and RNN models assessed by recall rate and F1-score were also significantly better than that of the LR model, in which the GRU model reached the best performance. In addition, the recall rates were different among different causes of death or by different prediction time windows. CONCLUSION The recurrent neural network model, especially the GRU model, is more effective in predicting PD patients' prognosis as compared with the LR model. This new model may be helpful for clinicians to provide timely intervention, thus improving the quality of care of PD.

Abstract
A new short-lived neutron-deficient isotope ^{220}Np was synthesized in the fusion-evaporation reaction ^{185}Re(^{40}Ar,5n)^{220}Np at the gas-filled recoil separator SHANS. Based on the measurement of the correlated α-decay chains, the decay properties of ^{220}Np with E_{α}=10040(18) keV and T_{1/2}=25_{-7}^{+14} μs were determined, which are in good agreement with theoretical predictions. From the new experimental results coupled with the recently reported α-decay data of ^{219,223}Np, the α-decay systematics for Np isotopes around N=126 was established, which allows us for the first time to test the robustness of the N=126 shell closure in Z=93 Np isotopes. The results also indicate that, in the region of nuclei with Z≥83, the proton drip line has been reached for all odd-Z isotopes up to Np.

Abstract
Objective: To determine the clinical benefits of internal mammary sentinel lymph node biopsy (IM-SLNB) acquired by breast cancer patients with clinically positive axillary lymph node (ALN), and further optimize the IM-SLNB indications. Methods: All primary breast cancer patients with clinically positive ALN from February 2014 to September 2017 were prospectively recruited in this study. IM-SLNB was performed under the guidance of the modified injection technique. The success rate and visualization rate of IM-SLNB, metastatic rate of internal mammary sentinel lymph node (IMSLN) and its related factors were analyzed, and the clinical benefits were accessed according to the current guidelines. Results: Among 126 patients, all of 94 patients (74.6%) who showed internal mammary drainage successfully underwent IM-SLNB. The incidence of internal mammary artery bleeding and pleural lesion were 4.3%(4/94) and 9.6%(9/94), respectively. The metastatic rate of IMSLN was 38.3% (36/94), which was significantly associated with the number of positive ALN (P<0.001) and tumor size (P=0.024). The lymph node staging of 94 patients who underwent IM-SLNB was more accurate. Among them, 36 cases with positive IMSLN underwent internal mammary radiotherapy (IMRT), while the other 58 cases with negative IMSLN avoided radiotherapy. Conclusions: IM-SLNB should be routinely performed in patients with positive ALN. IM-SLNB can provide more accurate staging and guide tailored IMRT to benefit more breast cancer patients.

Abstract
Objective: To investigate the application values of immunophenotypic analysis and molecular genetics in the diagnosis of acute promyelocytic leukemia (APL) . Methods: The retrospective analyses of flow cytometric (FCM) immunophenotypic anyalysis, chromosome karyotype and chromosome fluorescence in situ hybridization (FISH) of 798 outpatient or hospitalization APL patients referred to our hospital between May 2012 and December 2017 were performed to further study the application values of FCM and molecular genetics in the diagnosis of APL. Results: The sensitivity and specificity of FCM were 91.9% and 98.7% respectively. The typical characteristic immunophenotype for APL was as of follows: a high SSC, absence of expression of cluster differntiation (CD) CD34 and HLA-DR, and expression or stronger expression of CD33, consistent expression of CD13, CD9, CD123, expression of CD56, CD7, CD2 (sometimes) . The rest 10% of the cases harbored atypical APL phenotypes, generally accompanied by CD34 and/or HLA-DR expression, decreased SSC and often accompanied by CD2 expression, it was difficult to definitively diagnose APL by this FCM phenotype, and their diagnoses depended on the results of genetics or molecular biology tests. Compared with normal individuals, complex karyotypes APL with t (15;17) translocation, other variant translocations and variant t (11;17) , t (5;17) had no significant differences in terms of their FCM phenotypes. Conclusions: FCM could rapidly and effectively diagnose APL. Despite the fact that complex karyotypes with various additional chromosomal abnormalities were detected in approximately one third of APL cases in addition to the pathognomonic t (15;17) (q22;q21) , they had no observable impact on the overall immunophenotype. Molecular and genetic criteria were the golden criteria for the diagnosis of APL. About 10% of immunophenotyping cases relied on molecular genetics for diagnosis.

Abstract
Objective: To evaluate the value of intraoperative CT scanning in the treatment of fresh thoracolumbar burst fractures. Methods: From January 2008 to January 2015 , 161 patients with thoracolumbar fractures in Department of Orthopedics, Luohe City Central Hospital, were divided into two groups: 79 cases were treatment group which were treated with intraoperative CT scan and decompression mode was determined according to CT scan results during the period from October 2012 to January 2015. 82 patients as the observation group were treated without intraoperative CT scan and direct laminectomy were performed during the period. In the treatment group, it is no further decompression of the spinal canal when the CT showed a reduction of the fracture block into the spinal canal, if the intraoperative CT showed that the fractures still occupied the spinal dura mater according to the three-dimensional CT information, the position and the size of the fracture of the spinal canal were determined, and the unilateral laminectomy was performed corresponding to the position of the lamina and intervertebral ligamentum flavum. The operative time, bleeding volume, neurological function, height of the anterior vertebral compression and Cobb angle were compared between the two groups. Results: In the treatment group, CT scan showed 48 cases (60.8%) entered the spinal canal fracture completely or basically reset.31 cases (39.2%) still occupied the spinal canal compression spinal dura mater. There were significant differences in the operation time and bleeding volume between the two groups. The treatment group was less than the control group. There was no infection, secondary spinal cord injury, loose fixation and other complications. There was no difference in the ASIA classification before and after operation(χ(2)=0.268 vs χ(2)=1.372, P>0.05). The anterior vertebral height and COBB angle of the two groups were significantly improved compared with those before operation. There was no significant difference between the two groups in the postoperative height and COBB angle[(40.3±11.8)° vs(82.1±4.2)°, (-10.3±2.6)° vs(6.9±3.3)°, P<0.05], but after 2 years the difference was statistically significant between the two groups, to retain the rear ligament complex treatment group was significantly better than the control group. Conclusions: Patients of thoracolumbar vertebral fracture in hyperextension position combined with internal fixation can achieve good correction effect. Orthopedic postoperative CT scan and according to the results of the scan precision treatment can simplify the operation, there was no difference in clinical efficacy compared with total laminectomy, but some patients avoid the spinal canal decompression and part were treated by small fenestration laminectomy decompression, which is conducive to the protection of spinouts ligament complex integrity.

Abstract
Objective: To investigate the efficacy of bronchoalveolar lavage (BAL) and its influence factors in the treatment of Mycoplasma pneumoniae pneumonia (MPP) with atelectasis. Methods: A retrospective case control study was performed on hospitalized MPP patients with atelectasis and received BAL in the Department of Pulmonology, Children's Hospital Zhejiang University School of Medicine from January 1, 2015 to July 31, 2017. Fever relieved in 48 hours and chest imaging improved in one week after BAL were considered effective. Clinical data, including age, sex, blood routine tests, lactate dehydrogenase (LDH), cytokines, complications, fever duration before BAL, course of disease before BAL, sputum plug, atelectasis area and its CT values of atelectasis site were collected. Student's t test, Mann-Whitney U test, or chi square test were used. Results: (1) A total of 163 patients were enrolled, including 69 boys and 94 girls, with the ratio of 1∶1.36. Their ages ranged from 6 months to 12.6 years. (2) On the day of bronchoscope, 113 patients still had fever. They were divided into effective group (n=66) and ineffective group (n=47) according to whether fever was relieved in 48 hours after BAL. The effective group were found to have less sputum plug compared with the ineffective group (33% (22/66) vs. 57% (27/47), χ(2)=6.499, P=0.011). The other factors such as sex, age, fever duration before BAL, course of disease before BAL, C reactive protein (CRP), LDH, IL-2, IL-4, IL-6, IL-10, TNF, IFN-γ, atelectasis area and CT value showed no significant difference between the two groups (all P>0.05). (3)A total of 122 cases had chest imaging after BAL. According to chest imaging improvement, they were divided into effective group (n=81) and ineffective group (n=41). The effective group showed lower CT value ((58±9) vs. (63±8) HU, t=-2.436, P=0.017), IL-6 and IL-10 (M(Q(1), Q(3))) (21.0 (1.9, 48.4) vs. 36.4(21.8, 93.6), 4.9 (3.7, 9.6) vs. 7.7 (4.4, 12.0) ng/L, Z=-2.387,-2.009, P=0.017, 0.045). Sex, age, fever duration before BAL, course of disease before BAL, CRP, LDH, IL-2, IL-4, TNF, IFN-γ, atelectasis area showed no significant differences between the two groups (all P>0.05). (4) Patients were divided into sputum plug group (57 cases) and non sputum plug group (106 cases) according to bronchoscopic findings. The sputum plug group showed higher LDH, CRP, IL-6, IFN-γ, incidence of pleural effusion and extrapulmonary complications (585(433, 833) vs. 369 (312, 588) U/L, 42 (19, 103) vs. 25 (12, 45) mg/L, 38.8 (22.1, 71.3) vs. 20.7 (9.2, 48.3) ng/L, 33.1 (13.5, 89.3) vs. 12.7 (6.5, 33.6) ng/L, 73.7% (42/57) vs. 52.8% (56/106), 40.4% (23/57) vs. 17.0% (18/106)), with statistically significant differences (Z=-4.865,-3.435,-3.098,-3.704, χ(2)= 0.010, 0.001, all P<0.01) . Additionally, fewer patients showed fever relief within 48 hours after BAL in the cases with sputum plug cases compared those without sputum plug (44.9% (22/49) vs. 68.8% (44/64), χ(2)= 0.011, P=0.009). Fewer patients showed chest imaging improvement within one week after BAL in the cases with sputum plug compared with those without sputum plug, but did not show significant difference (56.5% (26/46) vs. 72.4% (55/76), χ(2)=0.073, P=0.056). Conclusions: BAL has some therapeutic effect on fever or atelectasis in MPP children complicated with atelectasis. Chest imaging improvement or fever relief may be hampered by sputum plug, increased IL-6 or IL-10.

Abstract
Objective: To investigate the effect of biofeedback therapy on metabolic syndrome (MS) and the effect of different levels of job stress on the outcome. Methods: The physicians in tertiary hospitals who were diagnosed with MS from January to December, 2016 were divided into biofeedback group and health education group according to different intervention methods, and moderate group, medium group, and high group according to different levels of job stress. A 6-month intervention was implemented from May to October, 2017. A two-way factorial design was used to analyze the main effect of biofeedback on physical and biochemical parameters and the interaction of biofeedback and job stress. Results: After 6 months of intervention, the patients in both the biofeedback group and the moderate group had significantly decreased waist circumference, body mass index, systolic blood pressure (SBP) , diastolic blood pressure (DBP) , and levels of triglyceride (TG) , total cholesterol, low-density lipoprotein cholesterol (LDL-C) , and fasting plasma glucose (FPG) and a significantly increased level of high-density lipoprotein cholesterol (HDL-C) (all P<0.05) ; the patients in both the health education group and the moderate group had significantly decreased SBP, DBP, and levels of TG, LDL-C, and FPG (P<0.05) . The factorial analysis of variance showed that there was a synergistic interaction between the intervention method and job stress level in SBP, DBP, TG, HDL-C, LDL-C, and FPG among MS patients (P<0.05) . The high group had significantly more improvements in all indices compared with the medium group and the moderate group (P<0.05) . Conclusion: Biofeedback therapy can effectively improve blood pressure, blood lipids, and blood glucose in MS patients, and is more effective for patients with high job stress level.

Abstract
Objective: To investigate the in vitro and in vivo effects of 5-aminolevulinic acid (5-ALA)-mediated photodynamic therapy against oral squamous cell carcinoma (OSCC) and preliminarily explore the possible mechanisms. Methods: SCC25 cells were divided into the control group (5-ALA of 0 mg/L) and the experimental group (5-ALA of 10, 25, 50, 100 and 150 mg/L). The production of protoporphyrin Ⅸ (PpⅨ) induced by 5-ALA in SCC25 cells was detected using the flow cytometry. SCC25 cells were divided into the control group (5-ALA of 0 mg/L), lazer alone group, 5-ALA alone group (5-ALA of 100 mg/L) and the 5-ALA combined with laser irradiation group (5-ALA of 5, 10, 25, 50 and 100 mg/L), the cytotoxicity of 5-ALA combined with laser irradiation (wave length 635 nm, power density 87 mW/cm(2) and laser dose 10.4 J/cm(2)) was evaluated in SCC25 cells using the methyl thiazolyltetrazolium assay (incubation times of 4, 8 and 12 h in each group) and the induction effect of combination treatment on the cell apoptosis was assessed by the flow cytometry (incubation time of 12 h in each group). The intracellular production of reactive oxygen species (ROS) triggered by 5-ALA combined with laser irradiation was determined using a fluorescence probe method (incubation time of 12 h in each group). A mouse OSCC xenograft model bearing SCC25 tumor was built, and the mice were divided into control group (saline), 5-ALA group (5-ALA of 50 mg/kg) and 5-ALA combined with laser irradiation group (5-ALA of 10, 25 and 50 mg/kg). Antitumor effect of 5-ALA combined with laser irradiation (wave length 635 nm, power density 158 mW/cm(2) and laser dose 94.8 J/cm(2)) was further measured. Results: 5-ALA induced the production of PpⅨ in SCC25 cells in a drug concentration (0-150 mg/L)-and incubation time (0-24 h)-dependent manner. When the 5-ALA concentration was 100 mg/L, the intracellular PpⅨ production was in a relatively stable state. Cell viability and apoptosis rate of 5, 10, 25, 50, 100 mg/L 5-ALA combined with laser irradiation are, respectively, (82.3±5.2)%, (3.13±0.38)%; (74.6±9.3)%, (5.38±0.55)%; (38.3±9.7)%, (17.97±2.72)%; (9.2±3.8)%, (24.47±3.37)%; (7.2±0.8)%, (43.01±5.96)%, which indicated that 5-ALA combined with laser irradiation notably inhibited the growth of SCC25 cells and also induced significant cell apoptosis compared with the control group [(96.3±6.0)%, (0.35±0.13)%, P<0.05]. After combination treatment (5-ALA of 5, 10, 25, 50 and 100 mg/L combined with laser irradiation, the mean fluorescence intensity of dichlorofluorescein is (1.46±0.12)×10(4), (2.16±0.30)×10(4), (3.57±0.34)×10(4), (81.70±13.05)×10(4), (113.00±7.35)×10(4), respectively, a large amount of ROS was produced in SCC25 cells compared with the control group [(0.96±0.15) ×10(4), P<0.05], which was in positive correlation with the intracellular PpⅨ content. 5-ALA (concentration of 10, 25 and 50 mg/kg) combined with laser irradiation greatly suppressed the tumor growth in SCC25 tumor-bearing mice compared to the control group (P<0.05). Conclusions: 5-ALA-mediated photodynamic therapy can trigger the generation of intracellular ROS that has significant cytotoxicity and apoptosis induction effect, and thus inhibit the tumor growth both in vitro and in vivo.
