Abstract
Isopsoralen is the main component of the Chinese medicine psoralen, which has antitumour activity and can be used for the treatment of osteoporosis. However, the mechanism behind its hepatotoxicity has not yet been elucidated. In this study, the hepatotoxicity of isopsoralen was investigated using zebrafish. Isopsoralen treatment groups of 25, 50 and 100 μM were established. The mortality, liver morphology changes, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), liver histopathology and mRNA levels of liver injury–related genes in zebrafish larvae were measured. The results showed that isopsoralen resulted in the development of malformed zebrafish, dose-dependent increases in ALT and AST, decreased liver fluorescence and weakened fluorescence intensity. Histopathological examination showed that high-dose isopsoralen caused a large number of vacuolated structures in the larvae liver. The polymerase chain reaction results showed a significant decrease in the mRNA levels of genes related to antioxidant capacity ( lfabp, gstp2 and sod1) and drug transport ( mdr1, mrp1 and mrp2), indicating that isopsoralen significantly inhibited liver antioxidant capacity and drug efflux capacity in zebrafish larvae. Isopsoralen is hepatotoxic to zebrafish larvae via inhibition of drug transporter expression resulting in the accumulation of isopsoralen in the body and decreased antioxidant capacity, leading to liver injury.

Abstract
BACKGROUND For cancer patients, health-related quality of life (HRQoL) is as important as other key outcomes, such as overall survival and tumor-free survival. Liver transplantation (LT), resection, and radiofrequency ablation (RFA) are 3 radical therapies for hepatocellular carcinoma (HCC) that result in similar survival. The main objective of this study was to assess and compare long-term HRQoL scores for patients with early-stage (tumor diameter ≤3 cm) HCC after LT, resection, or RFA. METHODS A total of 128 HCC patients with a single tumor ≤3 cm and who agreed to undergo LT, resection, or RFA were included in the present analysis. Postoperative HRQoL was evaluated by using the Medical Outcomes Study 36-Item Short Form Health Survey questionnaire. The 3 groups were compared at the 6-month and 3-year time points. RESULTS The 3 groups showed comparable 3-year HCC recurrence rates (P > .05). Compared with the LT and resection groups, the RFA group had significantly higher scores for bodily pain, general health, and vitality 6 months after surgery (all P values < .05). Moreover, at 3 years after surgery, the RFA group had higher scores for bodily pain and vitality than the other 2 groups (P < .05) and a higher general health score than the resection group. Other aspects of HRQoL were comparable among the 3 groups at both time points. CONCLUSIONS Due to its comparable HCC recurrence rate and superior long-term HRQoL scores relative to other radical therapies, RFA may be the first-choice treatment for solitary early-stage HCC.

Abstract
Real world study (RWS), a further verification and supplement for explanatory randomized controlled trial to evaluate the effectiveness of intervention measures in real clinical environment, has increasingly become the focus in the field of research on medical and health care services. However, some people mistakenly equate real world study with observational research, and argue that intervention and randomization cannot be carried out in real world study. In fact, both observational and experimental design are the basic designs in real world study, while the latter usually refers to pragmatic randomized controlled trial and registry-based randomized controlled trial. Other nonrandomized controlled and adaptive designs can also be adopted in the RWS.

Abstract
Objective: To analyze the application of vascular replacement technique with allogenic blood vessel in radical resection for pancreatic carcinoma. Methods: The clinical data of 33 patients with vascular invasion of pancreatic carcinoma who underwent radical resection from April 2013 to April 2017 in Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital were retrospectively analyzed. There were 14 males and 19 females with age of (62.5±10.6)years(ranging from 35 to 78 years). Vascular replacement technique with allogenic blood vessel was used on all patients who underwent radical resection for pancreatic carcinoma. The operation procedure was made according to the specific location of the carcinoma, and the allogenic blood vessel was selected according to the type of vascular invasion. The matching vessel was selected for replacement to the patient who was invaded only one vessel. And the "Y" type of iliac vein was selected for replacement to the patient who was invaded the confluence of portal vein, splenic vein and superior mesenteric vein. After the operation, the patients were followed up by telephone and outpatient review. Results: All of 33 patients were successfully completed the operations. There were 28 patients underwent pancreaticoduodenectomy with vascular replacement, and 5 patients underwent total pancreatectomy with vascular replacement. All the patients were confirmed pancreatic carcinoma and R0 resection according to the postoperative pathology. There were 16 patients with the carcinoma invasion the confluence of portal vein, splenic vein and superior mesenteric vein, 12 patients with the carcinoma invasion the superior mesenteric vein, and 5 patients with the carcinoma invasion the portal vein. There was no perioperative death in this group and no complications related to allogenic blood vessel. The incidence of postoperative complications was 18.2% (6/33), and the incidence of pancreatic fistula was 6.1% (2/33), all of which were biochemical fistula. There were 32 patients were followed up, and the follow-up rate was 96.9%. The median survival time was 14.6 months. The half-year, 1-year and 2-year survival rates were 75.6%, 37.6% and 27.4%. Conclusion: The application of vascular replacement technique with allogenic blood vessel for pancreatic carcinoma has a great significance for improving the R0 resection rate and the prognosis of patients.

Abstract
The activity of total thymidine kinase in serum (S-TK) has been used as a tumor maker for decades. To date such activity has been determined using [125]I-iodo-deoxyuridine as a substrate. The aim of this study was to develop a new, antibody-based technique for the measurement of cytoplasmic thymidine kinase (TK1) in serum. Both mono- and polyclonal antibodies against S-TK1 were used in dot blot assay. S-TK1 was characterized by SDS and IEF techniques. Sixty-five breast cancer patients were studied, including 17 preoperative and 38 postoperative tumor-free patients and 10 patients with metastases to the lymph nodes (N1–2). They were compared to patients with benign tumors (n=21) and healthy volunteers (n=11). S-TK1 was low (0–1.0 pM) in healthy volunteers, while in preoperative patients the level was increased 6–110-fold. Significant differences were observed between preoperative patients and healthy volunteers (p=0.005), preoperative patients and patients with benign tumors (p<0.001), and preoperative patients and postoperative patients without metastases (p<0.001). No significant difference was observed between preoperative patients and postoperative patients with metastases (p=0.191). The S-TK activity in preoperative patients was also high in serum, but no decrease was observed following surgery. In conclusion, the anti-TK1 antibody could be a good marker for monitoring the response of breast cancer patients to therapy.

Abstract
Objective: To explore the clinical efficacy of the modified laparoscopic placement of peritoneal dialysis catheters by nephrologists. Methods: A total of 188 patients diagnosed as end-stage renal disease (ESRD) were enrolled, who received catheter and continuous ambulatory peritoneal dialysis (CAPD) therapy from January 2011 to May 2016 in Zhejiang Provincial People's Hospital. They were divided into group A (with modified laparoscopic placement of peritoneal dialysis catheters, n=59) and group B (with conventional placement of peritoneal dialysis catheter, n=129). The demographic and clinical characteristics, past abdominal operation history, surgery time, hospital stay after operation, expenses for surgery and hospitalization, early and late complications including bleeding, pain, leakage, peritonitis and catheter displacement were observed. Results: Patients with previous abdominal surgery accounted for 11.9% in group A and 0 in group B(χ2=15.897, P<0.001). The duration of the operation was (38.9±12.8)min in group A and (64.1±12.7)min in group B(t=-6.466 6, P=0.000 0). The cost of the operation was (5 488.4±156.1) yuan in group A and (1 602.7±48.92) yuan in group B (t=257.129, P=0.000 0). Catheter displacement within one month was observed in 0 and 11.6%(χ2=7.455 3, P=0.003), pain in 15.3% and 41.9% (χ2=12.862 2, P=0.000), and catheter displacement after one month in 0 and in 16.3% (χ2=10.812 4, P=0.000) of the patients, respectively in group A and group B. The incidences of peritonitis within one month and beyond one month, leakage, bleeding and so on showed no difference between the two groups(P>0.05). Conclusions: Placement of PD catheter with laparoscope is suitable for renal failure patients with abdominal operation history and replacement PD catheter. It also has the advantages of shorter surgery time, less pain and lower incidences of catheter displacement, expanding the application of PD. However, bleeding, leakage, hernia and other complications are frequently seen.

Abstract
BACKGROUND It has been demonstrated that the prognosis of liver transplantation (LT) is significantly influenced by pretransplant factors, such as diabetes mellitus (DM). However, inconsistent observations are obtained. METHODS We comprehensively searched PubMed, Embase and Web of Science to identify eligible cohort studies to evaluate the impact of preexisting DM on LT prognosis. Overall mortality and graft loss, as the most frequently observed parameters, were used to evaluate the outcomes of LT. Hazard ratios (HRs) with their 95% confidence intervals (CIs) were pooled to assess the effect of DM. RESULTS 15,768 diabetic LT recipients and 60,176 non-diabetic LT recipients from 13 populations were included in this meta-analysis. Preexisting DM increased the risk for overall death of LT by 40% (95% CI 1.22-1.61), compared with DM-free patients. In addition, the risk for graft loss was also elevated by pretransplant DM (HR 1.28, 95% CI 1.07-1.54). Both analyses showed high heterogeneities (I 2 = 85.2 and 93.2%, respectively) and their sources were not identified by meta-regression analyses. In terms of the additive effect of hepatitis C virus (HCV) infection on poor outcomes of diabetic LT recipients, stratified meta-analyses were conducted. It was demonstrated that HCV infection increased the risk for mortality by 73% (95% CI 1.64-1.83), relatively higher than non-HCV recipients (HR 1.32, 95% CI 1.25-1.39) and general population (HR 1.40, 95% CI 1.22-1.61). CONCLUSION Preexisting DM predicts worse patient and graft survivals of LT. Concomitant HCV infection would further deteriorate this unfavorable impact. Given the high heterogeneities and the insufficient evidences, more studies are still warranted to support these observations.

Abstract
Thymidine kinase 1 in serum (STK1) of patients with gastric cancer was determined by two methods: ECL dot blot and radioactivity assay. Both measurements showed significantly different values for preoperative STK1 and healthy STK1 (p=0.012 for ECL dot blot and p=0.003 for the radioactivity assay). The preliminary results of ECL dot blot STK1 measurement showed that in tumor-free subjects the level of the enzyme was significantly reduced to 52.7% 35 days after surgery (n=8, p=0.0106). The decrease in STK1 levels in the tumor-free subjects paralleled the decline of the half-life of the STK1 enzyme. In patients with distant metastases (n=6) the enzyme level had increased to 173% 35 days postoperatively. By contrast, with the radioactivity assay no significant differences in thymidine kinase activity for 0-day-postoperative patients and 35-day-postoperative tumor-free patients was found (p=0.329). The activity decreased to 80% in 35-day-postoperative patients with metastatic disease. We suggest that the value of the half-life of STK1 measured by ECL dot blot can be used as a potential marker for monitoring the response to surgery in patients with gastric or other cancers one month after surgery.

Abstract
Nicotinic acid (NA) is ubiquitous in nature and its microbial degradation mechanisms are diverse. In this study, Pusillimonas sp. strain T2 was found to be capable of utilizing NA as sole carbon and nitrogen sources. This strain could completely degrade 300 mg l-1 NA within 3·5 h at 30°C and pH 7·0 and one of the degradation intermediate of NA was identified as 6-hydroxynicotinic acid (6HNA). The draft genome sequences of strain T2 were determined to have a total length of 3·3 M bp and 3054 proteins were predicted. The encoding genes of three-component NA hydroxylase (NahAB1 B2 ) genes were identified. The nahAB1 B2 genes were heterologously expressed in the non-NA-degrading Shinella sp. strain HZN7. The recombinant HZN7-pBBR-nahAB1 B2 converted NA into equimolar 6HNA, while the recombinants HZN7-pBBR-nahAB1 (lacking component B2 ) and HZN7-pBBR-nahAB2 (lacking component B1 ) could not convert NA. Cell-free extracts of HZN7-pBBR-nahAB1 B2 exhibited NA hydroxylase activity. After addition of an artificial electron acceptor (such as phenazine methosulphate, PMS), the NA hydroxylase activity was significantly increased. The Km and Vmax values for NA were 65·94 μmol l-1 and 260·80 ± 5·69 mU mg-1 , respectively, using PMS as an electron acceptor. This study provides a novel insight into the NA degradation by bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY Nicotinic acid (NA) serves as a model system for the degradation of N-heterocyclic aromatic compounds and the microbial degradation mechanisms are diverse. This is the first time that a three-component hydroxylase has been identified. This study provides a novel insight into the NA degradation by bacteria.

Abstract
Objective: To compare the cytogenetic response detected by conventional banding analysis (CBA) and fluorescence in situ hybridization (FISH) and to explore the correlation between the cytogenetic and molecular response in chronic myeloid leukemia (CML) patients during tyrosine kinase inhibitor (TKI) treatment. Methods: CBA, FISH and real-time quantitative reverse transcriptase polymerase chain reaction (RQ-PCR) methods were performed to detect the cytogenetic and molecular response simultaneously in 504 bone marrow samples from 367 CML patients who received TKI treatment. Results: Among 504 samples, 344 were detected to reach complete cytogenetic response (CCyR) by CBA, while 297 samples reached CCyR by FISH which were considered to carry BCR-ABL positive cells<1%. When the results of CBA, FISH and RQ-PCR were compared in 493 samples at the same time, it showed that in 337 samples with CBA-CCyR, 273 (81.0%) reached FISH-CCyR and 289 (85.8%) were BCR-ABL(IS) (International Scale, IS) ≤1% by RQ-PCR, compared to 9.0 (261/290) were BCR-ABL(IS) ≤1% among 290 samples with FISH-CCyR. There was no significant difference in the median value of BCR-ABL(IS) between samples in CBA-CCyR and FISH-CCyR (0.21% vs 0.13%, z=-1.875, P=0.061) . Furthermore, when the samples were divided into three groups according to BCR-ABL positive cells (0,>0~<1%, 1%~5%) by FISH, the statistical difference was observed, the proportion of samples with BCR-ABL(IS) ≤1% in the three groups were 94.1%, 57.6% and 27.7% respectively (χ(2)=43.499, P<0.001; χ(2)=9.734, P=0.003) , while the median value of BCR-ABL(IS) were 0.10%, 0.64% and 1.80% respectively (z=-5.864, P<0.001; z=-4.787, P<0.001) . Conclusion: FISH results were in good concordance with CBA in identify samples in CCyR, FISH was more sensitive and had better correlation with RQ-PCR results than CBA, but how to define FISH-CCyR need further study.

Abstract
Modulation and δ-doping strategies, in which atomically thin layers of charged dopants are precisely deposited within a heterostructure, have played enabling roles in the discovery of new physical behavior in electronic materials. Here, we demonstrate a purely structural "δ-doping" strategy in complex oxide heterostructures, in which atomically thin manganite layers are inserted into an isovalent manganite host, thereby modifying the local rotations of corner-connected MnO_{6} octahedra. Combining scanning transmission electron microscopy, polarized neutron reflectometry, and density functional theory, we reveal how local magnetic exchange interactions are enhanced within the spatially confined regions of suppressed octahedral rotations. The combined experimental and theoretical results illustrate the potential to utilize noncharge-based approaches to "doping" in order to enhance or suppress functional properties within spatially confined regions of oxide heterostructures.

Abstract
WHAT IS KNOWN AND OBJECTIVE Erlotinib is one of the epidermal growth factor receptor (EGFR) inhibitors and is widely used as a targeted therapy for advanced non-small-cell lung cancer (NSCLC). There are a few reports regarding ocular adverse effects of erlotinib. Herein, we report a case of rapid onset of ocular toxicity associated with overdosing of erlotinib. CASE DESCRIPTION A 72-year-old male with metastatic NSCLC developed conjunctivitis after accidentally taking erlotinib at a dosage of 300 mg/day for 4 days. Before that, the patient had been taking erlotinib at the prescribed dose of 150 mg/day for 17 days. Erlotinib was discontinued for 7 days, and the conjunctivitis was successfully treated symptomatically. The adverse effect did not recur when he resumed taking erlotinib 150 mg/day, suggesting the ocular change was related to the overdosing of erlotinib. WHAT IS NEW AND CONCLUSION Awareness and close monitoring of this adverse effect are helpful for doctors and pharmacists to identify inadvertent drug overdose. Patients should be provided comprehensive education before receiving targeted therapy.

Abstract
INTRODUCTION Red blood cell distribution width (RDW) is elevated in various inflammatory diseases, but its clinical significance in Henoch-Schönlein purpura nephritis (HSPN) in unknown. The aim of this study was to determine the value of RDW as a risk factor or marker for HSPN in children. METHODS This was a case-control study of 105 Henoch-Schönlein purpura (HSP) patients, 120 HSPN patients and 192 healthy controls. The relationship between RDW-coefficient of variation (RDW-CV) and the clinical characteristics of HSPN patients was determined by a multiple logistic regression analysis (MVLRA). Receiver operating characteristic (ROC) curves were applied to compare the diagnostic potential of the RDW-CV, a panel of routine markers and combinations of these indices. RESULTS The RDW-CV values were significantly higher in the HSPN group than the HSP group and controls (P < 0.001). Significant correlations were found between RDW-CV and ESR (P = 0.001). A combination of RDW-CV and ESR in a ROC curve showed 80% sensitivity and 84.9% specificity in the HSP patients, and 85.8% sensitivity and 93.8% specificity in the HSPN patients. The MVLRA revealed that RDW-CV (OR 1.69, 95% CI 1.16-2.48, P = 0.007) was an independent predictor of HSPN. CONCLUSIONS The RDW levels were highest in the HPSN group, suggesting that RDW, especially the combination of RDW and ESR, may have value when assessing the risk of HSPN.

Abstract
Intrauterine growth retardation (IUGR) is associated with the development of adult-onset diseases, including pulmonary hypertension. However, the underlying mechanism of the early nutritional insult that results in pulmonary vascular dysfunction later in life is not fully understood. Here, we investigated the role of tyrosine phosphorylation of voltage-gated potassium channel 1.5 (Kv1.5) in this prenatal event that results in exaggerated adult vascular dysfunction. A rat model of chronic hypoxia (2 weeks of hypoxia at 12 weeks old) following IUGR was used to investigate the physiological and structural effect of intrauterine malnutrition on the pulmonary artery by evaluating pulmonary artery systolic pressure and vascular diameter in male rats. Kv1.5 expression and tyrosine phosphorylation in pulmonary artery smooth muscle cells (PASMCs) were determined. We found that IUGR increased mean pulmonary artery pressure and resulted in thicker pulmonary artery smooth muscle layer in 14-week-old rats after 2 weeks of hypoxia, while no difference was observed in normoxia groups. In the PASMCs of IUGR-hypoxia rats, Kv1.5 mRNA and protein expression decreased while that of tyrosine-phosphorylated Kv1.5 significantly increased. These results demonstrate that IUGR leads to exaggerated chronic hypoxia pulmonary arterial hypertension (CH-PAH) in association with decreased Kv1.5 expression in PASMCs. This phenomenon may be mediated by increased tyrosine phosphorylation of Kv1.5 in PASMCs and it provides new insight into the prevention and treatment of IUGR-related CH-PAH.

Abstract
Objective: To investigate the effect of zinc finger E-box-binding homeobox 2 (ZEB2) on hepatitis B virus (HBV) replication and expression. Methods: HepG2, HepG2.2.15, and HepAD38 cells were cultured separately, and Western blot was used to measure the expression of ZEB2. HepG2.2.15 cells were cultured and transfected with ZEB2 expression plasmids or shRNA targeting ZEB2. Western blot was used to measure the expression of ZEB2 and HBV core proteins, quantitative real-time PCR was used to measure HBV 3.5 kb RNA and HBV DNA, Southern blot was used to measure HBV replicative intermediate, and ELISA was used to measure the expression of HBsAg and HBeAg, in order to clarify the effect of ZEB2 on HBV replication and expression. The dual-luciferase reporter system was used to analyze the effect of ZEB2 on HBV promoter, and the chromatin immunoprecipitation assay was used to detect the binding of ZEB2 to HBV promoter. The t-test was used for comparison of means between groups. Results: The expression of ZEB2 was inhibited in the cells with HBV replication. Overexpression of ZEB2 reduced the level of HBV replication and expression by about 50% (P< 0.05). After ZEB2 was downregulated by shZEB2-1 or shZEB2-2, the level of HBV replicative intermediate increased from 58.53 ± 3.43 to 112.80 ± 5.03, and 128.30 ± 2.31, the relative expression level of HBV 3.5 kb RNA increased from 1.00 ± 0.01 to 2.03 ± 0.02 and 2.32 ± 0.03, the level of HBsAg increased from 35.63% ± 1.57% to 81.87% ± 0.43% and 100.00% ± 2.18%, and HBeAg increased from 37.00% ± 0.70% to 88.00% ± 2.60% and 100.00% ± 0.75%. Furthermore, ZEB2 could bind to HBV core promoter and inhibit its transcriptional activity. Conclusion: ZEB2 inhibits HBV replication and expression through binding to HBV core promoter and inhibiting its transcriptional activity.

Abstract
OBJECTIVE Gastric cancer is a common malignancy with increasing worldwide incidence, and chemotherapeutic drugs for gastric cancer are not effective. Long non-coding RNA (lncRNA) has been proved to be important in different cancer progression. In this research, we investigated whether lncRNAs have relations with drug resistance in gastric cancer to find new potential targets for therapy, which can increase the survival time of the drug-resistant gastric patient. PATIENTS AND METHODS qRT-PCR was used to detect the expression of BCAR4 in 113 cases of gastric cancer tissue and adjacent tissue, and the clinical significance was also analyzed. MTT assays and Western blot were performed to cytologically determine the relationship between BCAR4 expression and cisplatin resistance, as well as to investigate the potential molecular mechanism involved. RESULTS Compared with the adjacent tissues, we found that BCAR4 was highly expressed in gastric cancer tissues. We also found that the expression of BCAR4 was significantly related to the size of the tumor, clinical classification and the survival time. In cytological experiments, we found the expression of BCAR4 was enhanced in cisplatin-resistant cell strains (SGC7901/DDP). What's more, overexpression of BCAR4 in SGC7901 cells increased resistance to cisplatin while reduced BCAR4 expression increased the sensitivity of SGC7901/DDP cells to cisplatin. Western blot experiments indicated that elevated expression of BCAR4 upregulated tumor stem cell-related biomarkers via regulating Wnt signaling pathway. CONCLUSIONS We showed that BCAR4 was closely related with the cisplatin-resistant gastric cancer. It might be a promising target for treating gastric cancer and improving the efficiency of chemotherapeutic drugs.

Abstract
OBJECTIVE To assess the diagnostic rate, safety and clinical application of percutaneous renal masses biopsy for advanced renal cell carcinoma patients. METHODS In this retrospective study, we collected the data of renal masses from the patients who underwent renal masses biopsy under ultrasound from April 2001 to December 2014 in Peking University First Hospital. A total of 75 patients who were undiagnosed or diagnosed with advanced renal cell carcinoma by the imageological method were enrolled in this study. The patient and lesion characteristics such as tumor size, pathology of tumor, histologic subtype, pathological grade, biopsied location and biopsied cores were recorded and analyzed. RESULTS Among all the 75 patients, biopsy was diagnostic in 64 cases (85.3%) and non-diagnostic in 11 cases (14.7%). Of the 64 diagnostic biopsies, 60 were malignant, including 37 (61.7%) renal cell carcinoma (RCC), 13 (21.7%) urothelial carcinoma and 10 (16.7%) other malignant masses. Of all the RCC subjects, 24 suffered from clear cell RCC, 5 papillary RCC, 3 collecting duct carcinomas, 1 unclassified RCC and 4 unknown subtypes. The 11 non-diagnostic biopsied samplings included inflammatory, blood and extrarenal tissue and normal renal tissue. The proportion of collecting duct carcinoma in RCC was 10.8% and the proportion of squamous carcinoma in urothelial carcinoma was 23.1%, which were both higher than the previous research findings. For the male and female groups, non-diagnostic yields were 6.5% and 30.4%, respectively (P=0.022). Of all the 75 patients, 13 renal cell carcinoma patients underwent the surgical treatment and got the results of postoperative pathology. Comparing preoperative biopsy pathological diagnosis with postoperative pathological diagnosis, we found the diagnostic correct rates for benign and malignant lesions, pathological subtype and pathological grade were 100%, 81.8% and 60%, respectively. Mild macroscopic hematuria occurred in 1 case after RMB and there were no serious complications in all the cases. CONCLUSION Percutaneous renal masses biopsy under ultrasound with a high diagnostic rate which can define the histologic subtype of renal cell carcinoma. With targeted therapy, more and more patients whose evaluation suggests local advanced disease or metastatic tumors adopt renal tumor biopsy to define the histologic subtype, which could avoid unnecessary surgical treatment.

Abstract
We used functional magnetic resonance imaging to examine whether motivational-salient cues could exert a differential impact on proactive (the restrain of actions in preparation for stopping) and reactive (outright stopping) inhibition. Fourteen high-frequency poker players, and 14 matched non-gambler controls, performed a modified version of the stop-signal paradigm, which required participants to inhibit categorization of poker or neutral pictures. The probability that a stop-signal occurs (0%, 17%, 25%, 33%) was manipulated across blocks of trials, as indicated by the color of the computer screen. Behavioral analyses revealed that poker players were faster than controls in categorizing pictures across all levels of proactive motor response inhibition (go trials). Brain imaging analyses highlighted higher dorsal anterior cingulate cortex activation in poker players, as compared to controls, during reactive inhibition. These findings suggest that, due to their faster rates of stimulus discrimination, poker players might have recruited more cognitive resources than controls when required to stop their response (reactive inhibition). Nevertheless, no main effect of stimulus type was found, on either proactive or reactive inhibition. Additional studies are, therefore, needed in order to confirm that investigating the dynamics between reactive and proactive inhibition offers a discriminative analysis of inhibitory control toward motivational-salient cues.

Abstract
Osteoporosis is characterized by the imbalance of two relatively independent processes-osteoblastogenesis and osteoclastogenesis. Calcineurin (Cn)/nuclear factor of activated T cells (NFAT)(Cn/NFAT) signaling pathway is involved in these two processes in bone metabolism, but its potential as a target to treat osteoporosis needs to be defined. The aim of this study is to investigate the inhibition of polypeptide 11R-VIVIT onCn/NFAT signaling pathway. Rat calvaria (RC) cells were prepared from experimental model of osteoporosis in rat.11R-VIVIT wasused to treat cultured RC cells from wide type (WT) rat or from osteoporosis (OP) rat, we then measured the expressions of NFATc1, osteopontin (OPN), osteocalcin (OC), cytokines, NFκB subunit p65 by real time PCR, western blot or immunofluorescence. Then ALP expression and staining, and alizarin red S (ARS) staining were employed to study the osteoblastodifferentiation. 11R-VIVIT regulates the expression of NFATc1, and some other molecules in Cn/NFAT signaling pathway, such as OPN and OC, at transcriptional level and protein level. Further, it can regulate the expression of inflammatory cytokine like IL-1beta, IL-10 and TNF-alpha and NFκB activity. Further, 11R-VIVIT can accelerate osteoblastodifferentiation of RC cells demonstrated by ALP and ARS staining.11R-VIVIT can stimulate the bone formation by decreasing NFATc1 expression and regulating the expression of inflammation related molecules.

Abstract
Objective: This study was conducted to analyze the clinical characteristics and pituitary function of patients with primary empty sella (PES). Methods: The clinical data from 123 hospitalized adult patients with PES from January 2010 to May 2016 were retrospectively studied. Results: (1) The average age of the 123 (male 43, female 80) PES patients was (59.2±13.6) years (ranging 24-92 years), among whom 61% patients were in the age group between 50-69 years. (2) The symptoms of the patients included fatigue (56.1%), headache (34.1%), nausea and vomiting (17.9%), gonadal dysfunction (17.1%), visual disturbance (5.7%) and hypopituitarism crisis (3.3%). (3) Hypopituitarism was found in 66 of the 123 patients. Among them, 36.6%, 31.7% and 17.1% were central hypoadrenalism, hypogonadism, and hypothyroidism, respectively.The percentage of hypopituitarism in complete PES was significantly higher than that in partial PES (P<0.05). (4) Sixteen patients were concomitant with other autoimmune diseases including 11 patients with Graves' disease and 2 with Cushing's syndrome due to adrenal adenoma. Conclusions: The incidence of hypopituitarism in PES was 53.7%, in which the pituitary-adrenal axis hypofunction was more common. An overall evaluation of the pituitary function was essential for the patients who had headache and fatigue, or with suspected PES. The patients with hypopituitarism should be given hormone replacement therapy in time and followed up afterword.

Abstract
This study investigated the effects of Moringa oleifera (MO) as a partial substitute of alfalfa hay on milk yield, nutrient apparent digestibility and serum biochemical indexes of dairy cows. MO was harvested at 120 days post-seeding. Fresh MO was cut, mixed with chopped oat hay (425:575 on a DM basis), ensiled and stored for 60 days. Sixty healthy Holstein dairy cows were allocated to one of three groups: NM (no MO or control), LM (low MO; 25% alfalfa hay and 50% maize silage were replaced by MO silage) or HM (high MO; 50% alfalfa hay and 100% maize silage were replaced by MO silage). The feeding trial lasted 35 days. The LM and HM diets did not affect dry matter (DM) intake, milk yield or milk composition (lactose, milk fat, milk protein and somatic cell count). The apparent digestibility of DM and NDF was lower for HM group than NM group. Additionally, there were no significant differences in serum biochemical indexes between the LM and NM groups. The HM group had lower serum concentrations of total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol and higher serum concentrations of urea than the NM group. The partial replacement of alfalfa hay (≤50%) and maize silage with MO silage had no negative effects on milk yield, in vivo nutrient apparent digestibility or serum biochemical indexes of lactating cows.

Abstract
Objective: Prostate cancer is commonly diagnosed among old men while younger men are rarely diagnosed with prostate cancer. In this study we identify clinical and pathological features of 154 patients with prostate cancer younger than 55 years old and to assist intreatment decisions. Methods: The medical records of 154 prostate cancer patients younger than 55 years old in Peking University First Hospital from Feb 1953 to Jun 2016 were reviewed, retrospectively. Data was collected including symptoms, digital rectal examination (DRE), prostate-specific antigen (PSA), Gleason score, tumor stage, treatment strategies. Results: The mean age was 50.9±4.5, and 25.3% patients were between 40-50 years. Fifty-six (36.4%) patients initially presented with lower urinary tract symptoms. A solid mass could be found by digital rectal examination in 48(31.2%) patients. All patients were diagnosed by pathology of biopsy or surgery. The median Gleason score was 8. Gleason 2-6, 3+ 4, 4+ 3, 8, 9-10 were 15 cases(9.7%), 28 cases(18.2%), 21 cases(13.6%), 15 cases(9.7%), 51 cases(33.1%), respectively. Based on 2009 AJCC TNM Classification criteria the distribution of tumor stage was T1, T2, T3, and T4 in 2(1.3%), 54 (35.1%), 60 (39.0%), and 37 (24.0%) patients. Forty patients (25.9%) were found with bone metastasis and four (2.5%) suffered from visceral metastasis. Fifty-three(34.4%)underwent hormonal therapy and 79(51.3%) underwent radical prostatectomy. Conclusion: Younger prostate caner patients usually presented with LUTS symptoms and were featured for higher tumor stage and aggressiveness. More optimal and personalized risk-based therapy options are required.

Abstract
OBJECTIVE Cardiovascular disease is one of the diseases threatening human health. Myocardial fibrosis is a major cause of cardiovascular diseases. Studies have shown that over expression of miR-203 can inhibit the fibrosis. Therefore, in this study, the effect of differential expression of miR-203 on fibrosis of cultured mouse cardiomyocytes was investigated. MATERIALS AND METHODS Activators and inhibitors of miR-203 were designed according to the sequence of miR-203, synthesized, and transfected into mouse cardiomyocytes to establish activator group, inhibitor group, and control group. The expression levels of fibrosis-related factors including FN, CTGF, and TGF-β1 were measured by Western blot and RT-PCR 24 h and 36 h after transfection. RESULTS Over-expression of miR-203 in mouse cardiomyocytes significantly decreased the expression levels of TGF-β1, CTGF, and FN in a time-dependent manner, compared with that in the control group (p <0.05). Inhibition of miR-203 expression in mouse cardiomyocytes significantly increased the expression levels of TGF-β1, CTGF, and FN 36 h after transfection, compared with that in the control group (p < 0.05). No significant differences were seen in the expression levels of TGF-β1, CTGF, and FN 24 h after transfection, compared with that in the control group (p >0.05). CONCLUSIONS Over-expression of miR-203 in mouse cardiomyocytes significantly decreased the expression levels of TGF-β1, CTGF, and FN, which might be used as a detection index for prediction of fibrosis.

Abstract
OBJECTIVE To understand the dynamic maternal measles antibody level in infants in Guangzhou. METHOD Women who delivered babies in a maternal and child health care hospital in Guangzhou and their infants who were never affected by measles were included in our study. All the serum samples collected from mothers and infants were tested by using enzyme linked immunosorbent assay(ELISA)for the quantitative measurement of measles IgG antibodies. A longitudinal sero-epidemiological study was conducted to investigate the duration of the presence of measles maternal antibodies in infants based on the measurement at different time points(0, 3, 5, 7 month). RESULT A total of 689 mothers and their 691 infants(two pairs of twins)were included in the study. The concentration and the sero-positivity rate of measles antibody in mothers was 513.8 mIU/ml and 81.6% respectively. The concentration and the sero-positivity rate of measles antibody in infants was 732.8 mIU/ml and 87.3%, respectively. The measles antibody levels of newborns were positively associated with those of mothers(r=0.917 5, P<0.001), which declined rapidly at 3 months after birth and mostly turned to be negative at 7 months after birth. Measles antibody turned be negative at 3 months after birth in low, middle level groups, but remained to be positive in high level group at 5 months after birth. CONCLUSION The maternal measles antibody could rarely protect infants at age of 8 months even though mother had been vaccinated or acquired natural immunity. It is suggested to adjust the time of the first dose measles vaccination in infants and increase the measles antibody level of child bearing aged women to reduce the incidence of measles in infants.

Abstract
OBJECTIVE To evaluate the efficacy and safety of domestic human recombinant FSH(rhFSH)in women with anovulation of WHO group Ⅱ. METHODS A randomized, blind, parallel-controlled, non-inferiority and multicenter study was performed. A total of 534 admitted to 13 hospitals from May 2008 to August 2009. There were 531 women with ovulatory disorder was included in the statistical analysis, were randomly divided into test group(domestic rhFSH, n=352)and control group(imported rhFSH, n=179). Percentage of cycle with mature follicle, ovulation rate, clinical pregnancy rate, multiple pregnancy rate, ovarian hyperstimulation syndrome(OHSS)and adverse events were observed. RESULTS No statistical significant differences(P>0.05)were observed between the two groups in terms of the efficiency on mature follicle[91.8%(323/352)versus 88.8%(159/179)], ovulation rate[91.3%(295/323)verus 90.6%(144/159)], clinical pregnancy rate[19.2%(62/323)verus 18.2%(29/159)], the number of the follicles<14 mm, the level of serum LH and progesterone, the thickness of endometrium on the day of hCG administration. The number of follicle≥18 mm and 14 mm≤follicle<18 mm and the level of serum estradiol on the day of hCG in the test group were significantly higher than those in the control group(P<0.05). The number of days of rhFSH administration in the test group was significantly less than that in the control group[(9.8±2.2)versus(11.4± 0.6)days, P<0.05], the dosage of rhFSH was significantly lower than that in the control group[(879 ± 419)versus(1 043±663)U, P<0.05]. The multiple pregnancy rate in the test group was significantly higher than that in the control group[21%(13/62)versu 10%(3/29), P<0.05]. The incidence of OHSS and adverse events were similar between the two groups(P>0.05), and no other adverse events were observed in test group during treatment. CONCLUSION Ovarian stimulation with domestic rhFSH is effective, safe and economical in women with anovulation of WHO group Ⅱ.

Abstract
There is great heterogeneity of immunity among patients with cryptococcosis, and severe immunodeficiency can lead to negative clinical outcomes. Underlying disease is a poor surrogate for immune status and inferior in predicting an individual’s prognosis. This study was intended to determine whether T-lymphocyte subgroups would be more suitable indicators regarding the severity of infection and clinical outcomes of such patients. We retrieved clinical data on 101 patients with cryptococcosis and compared the validity of multiple parameters (underlying disease and T-lymphocyte subgroups) in predicting the severity of infection and clinical outcome in these patients. For patients with CD4+ T-lymphocyte counts lower than 400/μL, the odds ratio of disseminated cryptococcosis was 23.3 (P = 0.005). There was a moderate negative correlation between CD4+ T-cell count and Apache II score (−0.609, P < 0.001). Mortality among patients with low levels of CD4+ T lymphocytes was significantly higher than among those with normal levels (23.8% vs 5.3%, P = 0.016). However, the difference was not significant if the patients were grouped by underlying disease (P = 0.067). The CD4+ T-lymphocyte count in peripheral blood is a simple and more accurate biomarker for predicting severity of infection and clinical outcome in patients with cryptococcosis.

Abstract
Objective: To analysis of the possible cause and surgical diagnosis and treatment strategies of acute gangrenous cholecystitis (AGC) after biliary stent drainage. Methods: The clinical data of 273 patients who received biliary stent drainage in Beijing Chaoyang Hospital from January 2015 to March 2016 were analyzed retrospectively. Among them, 22 patients who underwent surgical treatment were divided into two groups: 9 cases of AGC group and 13 cases of non-AGC group. The risk factors of AGC and surgical approach were analyzed. Result: All 22 patients underwent laparoscopic surgery. In AGC group, 1 patient with toxic shock died of multiple organ viscera function failure caused by infection, and 1 patient with gallbladder triangle inflammatory adhesion suffered from biliary leakage. The postoperative pathology of 2 patients was acute gangrenous cholecystitis. Non-AGC group had no death, bile duct injury and bleeding, with postoperative pathology of chronic cholecystitis. Patients were followed up for 2 month to restore well, without biliary calculi residual. Operation time, intraoperative blood loss, hospitalization days and hospitalization expenses of AGC group were higher than those of non-AGC group. Conclusion: The advocated AGC after biliary stent drainage should actively surgery after early diagnosis and endoscopic therapy should not be repeated. Laparoscopic surgery is a safe and effective treatment for AGC after carotid stenting.

Abstract
OBJECTIVE Acute myocardial infarction (AMI) contributes to be a significant public health problem, and it is the leading cause of morbidity and mortality in the world. However, the molecular mechanisms underlying AMI is poorly known. The purpose of this study was to investigate the change of plasma microRNA-99a (miR-99a) level in AMI patients and its potential clinical value. PATIENTS AND METHODS Plasma samples from 54 patients with AMI and 30 healthy volunteers were collected. Quantitative real-time PCR (qPCR) and ELISA assays were used to detect the expression of circulating plasma miR-99a and of cardiac troponin I (cTnI)/creatine kinase-MB (CK-MB), respectively. AMI patients were categorized into subgroups according to the number of stenosed coronary vessels, and the association between the plasma miR-99a level and the severity of AMI was analyzed. The expression level of miR-99a was also evaluated in patients receiving percutaneous coronary intervention (PCI). RESULTS The expression of miR-99a was significantly downregulated in patients with AMI compared with the normal controls (p < 0.01). In the AMI patients, miR-99a level had a negative correlation with cTnI level (r = -0.8202, p < 0.01) and CK-MB (r = -0.6924, p < 0.01). Also, the expression of miR-99a was markedly lower in patients with more stenosed coronary vessels (p < 0.01). The relative expression level of miR-99a in AMI patients was significantly increased after receiving PCI (p < 0.01). CONCLUSIONS The expression level of plasma miR-99a was remarkably reduced following AMI and closely associated with the severity of AMI. Therefore, it was a promising novel diagnostic biomarker for AMI.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a hepatic presentation of obesity and metabolic syndrome. MicroRNA 26a (Mir-26a) has been reported to play functions in cellular differentiation, cell growth, cell apoptosis and metastasis. A recent paper indicated that Mir-26a regulated insulin sensitivity and metabolism of glucose and lipids. However, the role of Mir-26a in NAFLD still needs to be investigated further. In our current study, vectors encoding pre-Mir-26a (LV-26a) and an empty lentiviral vector (LV-Con) delivered approximately 2 × 107 transforming units of recombinant lentivirus were injected into mice through the tail vein. LV-26a-infected mice were protected from glucose dysmetabolism and showed markedly decreased total liver weight, hepatic triglyceride deposition and serum alanine transaminase (ALT) concentration when compared with LV-Con-treated mice. LV-26a-treated mice also exhibited decreased infiltration of immune cells in the liver - something attributed to reduce infiltration of T cell receptor (TCR)-γδ+ , granulocyte-differentiation antigen-1 (Gr-1)+ cells and CD11b+ cells. Next, we found that Mir-26a inhibited the expression of interleukin (IL)-17 and IL-6 in vivo and in vitro. Furthermore, the decreased expression of IL-17 in the liver tissue induced by Mir-26a was abrogated completely by IL-6 overexpression. The decreased total liver weight, hepatic triglyceride deposition and serum ALT concentration induced by Mir-26a was also abrogated completely by IL-6 over-expression. In conclusion, the Mir-26a-IL-6-IL-17 axis regulates the development of NAFLD in a murine model.

Abstract
OBJECTIVE To explore the clinical pathological characteristics and improve the recognition in the diagnosis and treatment of incidental (stage T1a-T1b) prostate cancer. METHODS Seven hundred and seventy-one patients who underwent TURP from May 2004 to September 2013 were analyzed retrospectively. In our institution, TURP specimens should be totally submitted in an extensive sampling method. The tumor area was outlined by estimation of an experienced genitourinary pathologist and calculated by the image analysis system software (Image J 1.47 h). The tumor area was then multiplied by the thickness of tissue. The total sum of all tumor volume was the estimated tumor volume. The clinical and pathological factors, follow-up results were obtained and we aimed to collect information about the period of watchful waiting (WW), PSA progression status, intervention status during the follow-up, the reason for intervention on WW and the type of intervention. RESULTS The average age of 771 patients was (71.3±5.9) years old, and the average BMI was (23.9±3.1) kg/m2, preoperative average tPSA was (4.4±2.8) μg/L. Eighty-six (11.2%) cases of incidental prostate cancer were detected. The patients in T1a group (77 cases, 89.5%) had tumor volumes of (12.3±12.6) mm3, and the patients in T1b group had tumor volumes of (105.1±41.8) mm3.The range of tumor volume was 0.4-180.2 mm3. The volume of all the 86 cases was less than 500 mm3 as the threshold of insignificant cancer. All the patients were managed by WW. The mean follow-up time was 88.9 (27.9-150.1) months.The Gleason score was <7 in 79 patients, and ≥7 in 7 patients. There was no significant difference in age, preoperative tPSA, preoperative PSAD, postoperative tPSA, prostate volume and TURP resection between T1a group and T1b group (P>0.05). Among 84 patients without follow-up losts, PSA progression occurred in 5 patients. One T1a patient underwent radical prostatectomy (RP) as an intervention, and 3 patients underwent hormone therapy. One patient in T1b group underwent radiotherapy for PSA progression and one was treated because of patient preference without evidence of disease progression. There were no patients who died due to prostate cancer. CONCLUSION Eighty-six (11.2%) cases of incidental prostate cancer were detected. The tumor volume of all the cases was insignificant cancer.The clinical outcomes of IPCa were satisfactory with the initial treatment of WW in the Chinese population.

Abstract
BACKGROUND AND OBJECTIVE Mannose-binding lectin (MBL) plays an important role in innate immunity. MBL deficiency is usually caused by mutations in exon 1 of the MBL structural gene (MBL2). Our aim was to investigate MBL2 polymorphisms and their relation to salivary levels of periodontal inflammatory/tissue destruction markers and two major periodontitis-associated bacteria. MATERIAL AND METHODS Salivary samples from 222 subjects were available for genotyping by pyrosequencing. The subjects between 40 and 60 years of age and having a minimum of 20 teeth were divided into three periodontal groups: 80 had generalized periodontitis, 65 had localized periodontitis and 77 were periodontitis-free. A comparison between their MBL2 genotypes and salivary detection rates and levels of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis as well as interleukin -1β, matrix metalloproteinase -8, and tissue inhibitor of matrix metalloproteinase (TIMP)-1 was performed. RESULTS The frequencies of the MBL2 wild-type (A/A), heterozygote variants (A/O) and homozygote variants (O/O) were 69.4%, 26.6% and 4%, respectively. In A. actinomycetemcomitans-positive subjects having homozygote or heterozygote MBL2 variants, the salivary concentrations of IL-1β (p = 0.010) were elevated and those of TIMP-1 (p = 0.001) were decreased. In addition their matrix metalloproteinase -8/TIMP-1 ratio was higher (p < 0.001) and they had more pocket teeth (p = 0.012) than subjects negative for A. actinomycetemcomitans. CONCLUSION Our findings indicate that the carriage of A. actinomycetemcomitans may facilitate extended periodontal inflammation and destruction in subjects with a variant form of human MBL2.

Abstract
OBJECTIVE The aim of the study is to investigate the cardiac compensatory function change in senior people with Coronary Artery Disease (CAD) by Quantitive Dobutamine Stress Echocardiography (DSE) and Tissue Doppler Imaging (TDI). PATIENTS AND METHODS All of the 98 senior people (age >60) who were suspected to have CAD received the examination of DSE and TDI. The mean systolic peak velocity (Sa), early diastolic peak velocity (Ea) and late diastolic peak velocity (Aa) of mitral annulus were measured in a different dose of dobutamine stress. Besides, the coronary angiography (CAG) was done within 2 weeks for the 98 senior people. RESULTS In the basic status, the mean Sa, Ea and Aa were not significantly different between the patients from the normal group and CAD group. However, under a 20 μg/kg·min dose of dobutamine stress, significant differences of mean Sa and Ea between two groups were observed. For the mean Aa, a significant difference could be observed with the dose of 40 μg/kg·min. CONCLUSIONS Both the cardiac systolic and diastolic compensatory function were lower in the CAD group than the normal group, which is detectable in the 20 μg/kg·min dose of dobutamine stress status. In other words, Quantitive Dobutamine Stress Echocardiography is a safe, efficient, non-invasive diagnostic method. It can reflect the compensatory cardiac function of the patients with CAD.

Abstract
The current study investigated the relationship between the implantation angle of the acetabular component and the change in the pelvic postural angle during hip arthroplasty surgery. One pelvis with a left lower limb prosthesis was used. Total hip arthroplasty on the left pelvis was simulated with the help of a computer-assisted navigation system. The pelvis revolved around the horizontal, longitudinal and sagittal axes at different angles, and the anteversion and abduction of the acetabular component were measured. The changing angle of the pelvis rotating around the horizontal and longitudinal axes greatly influenced acetabular component anteversion. The changing angle of the pelvis rotating around the sagittal axis had a relatively great influence on the acetabular component abduction angle. The change in the postural angle of the pelvis had a great influence on the installation angle of the acetabular component. It is important to standardize posture prior to the operation.
