ABSTRACT
Objective@#To investigate the mental health literacy levels among residents in Ningbo City, so as to provide the evidence for implementing the mental health service policy and targeted mental health education.@*Methods@#Permanent residents at ages of 12 years and older were recruited in Ningbo City using the multi-stage stratified random sampling method from August to December, 2020. Subjects' mental health literacy levels were evaluated using the national mental health literacy survey of China, and the gender-, age-, region- and educational level-specific levels of mental health literacy were investigated.@*Results@#A total of 6 654 questionnaires were allocated, and 6 392 valid questionnaires were recovered, with an effective recovery rate of 96.06%. The respondents included 2 967 men ( 46.42% ) and 3 425 women ( 53.58% ). The respondents were predominantly at ages of 18 to 44 years ( 2 705 residents, 40.19%) , lived in urban areas ( 3 823 residents, 59.81% ), and had an educational level of junior high school and below ( 3 195 residents, 49.98% ). The level of mental health literacy was 19.06%, and the score of mental health knowledge was ( 64.06±18.39 ) points. In the dimension of mental health skills, the scores of interpersonal support, cognitive reappraisal and transferred attention were ( 2.58±0.51 ), ( 2.45±0.57 ) and ( 2.82±0.49 ) points, and the score of mental health awareness was ( 3.63±0.47 ) points. A higher level of mental health literacy was seen in women than in men ( 20.64% vs. 17.22%, P<0.05 ) and in urban residents than in rural residents (20.95% vs. 16.23%, P<0.05 ). In addition, there were age- and educational level-specific levels of mental health literacy among residents ( P<0.05 ), and a higher level was seen in residents at ages of 18 to 45 years ( 28.98% ) and with a bachelor degree (40.89% ).@*Conclusions@#A high level of mental health literacy is found in residents in Ningbo City. Mental health promotion campaigns are recommended among men, rural elderly residents with a low educational level.
ABSTRACT
Bariatric surgery has been proven to be an effective way to relieve obesity and related metabolic diseases. Complications after bariatric surgery mainly include postoperative bleeding, anastomotic leakage, gastroesophageal reflux, dumping syndrome and so on. Deep vein thrombosis is a rare complication, with low incidence in many literatures. However, deep vein thrombosis is an important cause of pulmonary embolism. Once pulmonary embolism occurs, the difficulty of treatment and mortality are both high. The authors summarize the related literature on venous thromboembolism after bariatric surgery, and briefly describe the strategies of prevention and treatment of venous thromboembolism.
ABSTRACT
Purpose@#The purpose of the study is to determine the prevalence and predictors of OSA in Chinese bariatric surgery candidates. @*Materials and Methods@#The clinical data were collected from 326 patients evaluated for bariatric surgery and referred for polysomnography. Multiple logistic regression was used for identifying independent predictors of presence of OSA and ROC curve analysis to determine the best cut-off value for continuous variable. @*Results@#Baseline BMI and age were 33.3±3.7 kg/m2 and 24.3±3.1 years. 62.9% of the patients fulfilled the diagnostic criteria for OSA; Of these, 22.7% had mild OSA; 11.3% had moderate OSA, and 28.8% had severe OSA. The prevalence was significantly higher in males (84.2%) than in females (47.3%) (P＜0.001). The superobese patients and the obese patients aged older than 50 years that all of those were diagnosed with OSA. A multivariate logistic regression model displayed that increasing age, BMI and neck circumference together with presence of habitual snoring and male sex were identified as risk factors of OSA. The best cut-off values for the presence of OSA for age, BMI, neck circumference were 24.5 years, 39.45 kg/m2 , 40.40 cm. @*Conclusion@#The prevalence of OSA is very prevalent (62.9%) in Chinese bariatric surgery candidates, especially in male patients (84%). Age, BMI and neck circumference together with presence of habitual snoring and male sex are independent predictors of OSA in these patients. As clinical predictors are not enough to be a properly screening for OSA, routine PSG testing should be recommended to bariatric surgery candidates.

ABSTRACT
@#The incidence of rib fracture in patients with chest trauma is about 70%. Simple rib fractures do not need special treatment. Multiple rib fractures and flail chest are critical cases of blunt trauma, which often cause serious clinical consequences and need to be treated cautiously. Nowadays, there is a controversy about the diagnosis and treatment of multiple rib fractures and flail chest. In the past, most of the patients were treated by non-operative treatment, and only less than 1% of the patients with flail chest underwent surgery. In recent years, studies have confirmed that surgical reduction and internal fixation can shorten the hospital stay, and reduce pain and cost for patients with flail chest, but there is still a lack of relevant clinical consensus and guidelines for diagnosis and treatment, which leads to great differences in clinical diagnosis and treatment plans. This article reviewed the treatment, surgical indications and surgical timing of multiple rib fractures and flail chest.
ABSTRACT
Objective:To evaluate the diagnostic and therapeutic effect of SpyGlass direct visualization system (SpyGlass) on cholangiopancreatic duct stenosis and large bile duct stones.Methods:Patients with cholangiopancreatic duct stenosis or large bile duct stones of indeterminate reasons who underwent SpyGlass at Hangzhou First People′s Hospital from September 2012 to August 2018 were recruited. Cholangiopancreatic duct stenosis were visually diagnosed using SpyGlass, and some patients underwent Spybite biopsy. Large bile duct stones were treated with SpyGlass-guided laser lithotripsy under direct visualization. The procedure success rate, clinical success rate, and adverse event incidence associated with SpyGlass were analyzed.Results:SpyGlass was performed to diagnose and treat 114 patients with bile duct stricture, 11 patients with pancreatic duct stricture and 19 patients with large bile duct stones. The total procedure success rate was 98.6% (142/144). The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of SpyGlass visual diagnosis of bile duct stricture of indeterminate reasons were 97.1% (67/69), 95.3% (41/43), 96.4% (108/112), 97.1% (67/69), and 95.3% (41/43), respectively. The accuracy of SpyGlass visual diagnosis of pancreatic duct stricture of indeterminate reasons was 100.0% (11/11). Of the 19 patients with large bile duct stones, the lithotripsy success rate was 89.5% (17/19). The success rate of primary extraction was 73.7% (14/19), and that of secondary extraction was 100.0% (5/5). The total extraction success rate was 100.0% (19/19) Four patients (2.8%) had postoperative complications, including three cases of acute cholangitis and one case of mild acute pancreatitis.Conclusion:SpyGlass is accurate and safe in the diagnosis of cholangiopancreatic duct stenosis. It is also effective and safe for treating large bile duct stones combined with laser lithotripsy.

ABSTRACT
Objective To examine the relationship between quetiapine serum concentration,dose,therapeu-tic efficacy and side effects in male patients with schizophrenia.Methods Sixty-three male patients with schizo-phrenia were collected.They were treated openly for 8 weeks with quetiapine,the dose was adjusted according to clini-cal improvement and tolerance.The plasma quetiapine concentrations,therapeutic efficacy and adverse drug reactions were observed after the 4 -week treatment period,and at the end of the 8 weeks of the treatment.Results After 4 weeks,the serum concentration had significant correlation with age,the disease duration and education level.After 8 weeks,there was significant correlation between serum concentration and age.We found a correlation between dose and serum concentration of quetiapine,and no relationship between serum concentration and PANSS scores.Side effects were correlated with 4 weeks′serum concentrations.Conclusion Quetiapine is effective for male patients with schizophrenia.Age,quetiapine dose and side effects have significant correlations with the serum concentration.It appears that plasma quetiapine concentration has no effects on therapeutic efficacy.
ABSTRACT
(E)-Methyl-4-aryl-4-oxabut-2-enoate (YH-8) is a novel PKnB protein kinase inhibitor with good anti-tuberculosis activity. To evaluate its pharmacokinetics in rats, a sensitive and selective high performance liquid chromatography-tandem mass spectrometric (LC--MS/MS) method has been developed and validated for the quantification of YH-8 in rat plasma for the first time. Samples were pre-treated using a liquid--liquid extraction with ethyl acetate and the chromatographic separation was performed on a C18 column by gradient elution with methanol--water as the mobile phase. YH-8 was detected using a tandem mass spectrometer in positive selected reaction monitoring (SRM) mode. Method validation revealed good linearity over the range of 1-500 ng/mL for YH-8 with a lower limit of quantification (LLOQ) of 1 ng/mL. Intra- and inter-day precision of YH-8 assay in rat plasma samples were 2.0%-6.8%, with accuracy of the method being 100.69%-106.18%. Stability test showed that when spiked into rat plasma, YH-8 was stable for 12 h at room temperature, for up to 15 days at -70 °C, and after three freeze-thaw cycles. Extracted samples were found to be stable over 12 h in an auto-sampler. The method was successfully applied to the pharmacokinetic study of YH-8 in rats after oral administration at 100 mg/kg and 200 mg/kg.
ABSTRACT
For screening the potential drugs as anti-liver fibrosis candidates, we established a high- throughput drug screening cell model based on COL1A1 promoter. The activity of COL1A1 promoter and luciferase reporter gene can be elevated by TGF-β1, and inhibited by candidate drugs. We constructed a recombined plasmid with COL1A1 promoter and luciferase reporter gene pGL4.17, the activity of COL1A1 promoter was reflected by fluorescence intensity. COL1A1 promoter activity was detected by Dual-Luciferase Reporter Assay System, it came that the relative luciferase activity of COL1A1 promoter was 15.98 times higher than that of control group induced by TGF-β1, showing the recombined plasmid could be used in cell model. The recombined plasmid was transfected into human hepatic stellate cells LX2, detected the effect of potential drugs, and obtained a stable expression system through stable transfection and monoclonal cell culture. A sample which could reduce COL1A1 promoter activity signally by our cell model, decreased collagen I mRNA and protein expression detected by real-time RT-PCR and Western blotting. It indicates this novel cell model can be used in high-throughput drug screening of potential anti-liver fibrosis drugs.
ABSTRACT
Objective To evaluate the value of immune cell functional assay (ImmuKnow CD4+ T cell ATP assay) in monitoring immune status in renal recipients.Methods A total of 131 adult renal transplant recipients who received transplantation for the first time were under investigation.According to the dynamic monitoring ATP concentration before operation,2 week,1,3,6 months after operation and during infect or rejection,samples were divided into the following groups:health control group (HC),pretransplant (Pre-Tx) group,stable (Tx) group,infect group,acute rejection (AR) group,acute kidney injury (AKI) group.Immune cell functions were detected by ImmuKnow CD4+ T cell ATP assay.Lymphocyte subsets (CD4+/CD8+) were analysed and serum concentrations of FK506 were tested.Mixed lymphocyte reaction(MLR) was analysed.Results The ATP concentration was no significant difference between Pre-Tx and HC group.The ATP concentration of 2 weeks,1 months after operation were significantly higher than Pre-Tx group (P ＜ 0.01).After 3 months,6 months follow-up,the ATP concentration stabilized with time.The ATP concentration of AR group was significantly higher than other three groups (Tx,infect and AKI group,all P ＜ 0.05).The correlation coefficient between the ATP concentration and MLR,CD4+/CD8+,FK506 level were R2=0.0072,R2=10-6,R2=0.004 respectively (all P ＞ 0.05).Conclusions The cell-mediated immunity of recipients is relatively strongger during the first month after transplantation.The ATP concentration is not related to the levels of MLR,CD4+/CD8+,FK506.ImmuKnow ATP assay is a valuable predictor in acute rejection diagnosis.
ABSTRACT
Objective To compare the difference of ELISA and LABScreen in detecting HLA antibodies and evaluate their effects on allograft rejection.Methods Consecutive patients undergoing kidney transplantion from November,2008 to December,2009 in the First Affiliated Hospital and the following up patients during the same period,with abnormal Scr who had completed kidney biopsies,were included in this study.Patients' HLA antibodies were detected by ELISA (Lambda antigen tray,LATTM) and LABScreen Mix Beads (LABScreen MIX,One Lambda,Canoga Park,CA,USA) or LABScreen Single antigen beads (LABScreenTM single antigen beads,One Lambda,Canoga Park,CA,USA).Patients' Scr were also detected at different time potints.Results There were 277 patietns included.Among them 145 (52.3％) cases were HLA antibody positive detected by LABScreen,which including 118 cases ELISA negative but LABScreen positive,and 27 cases both ELISA and LABScreen positive.No case was ELISA positive but LABScreen negative.Among 118 cases which were LABScreen positive but ELISA negative,41 (34.7％) cases happened acute or chronic rejection.However,only 24 cases happened rejection in 132 double negative cases (18.2％,P =0.003).There were 31％ patients in rejection group while only 12.8％ patients (P=0.01) in non-rejection group whose HLA antibody fluorescence intensity detected by LABScreen single antigen beads still increased two weeks after transplantation.Conclusion LABScreen is more sensitive than ELISA in detecting HLA antibodies,and its result highly correlates with the incidence of allograft rejection.

ABSTRACT
Ansamycins, such as rifamycin and ansamitocin, usually consist of a group of structural similar components. Geldanamycin, a benzenic ansamycin, has been found to consist of four structural similar components. We analyzed the geldanamycin (GDM) preparation from Streptomyces hygroscopicus 17997 by LC-ESI(+)-MS/MS, and discovered five novel and one known GDM analogues in trace amounts. Based on the ESI(+)-MS/MS spectra of these GDM analogues, and the present understanding of GDM biosynthesis, we proposed the possible chemical structures of these GDM analogues. Three novel GDM analogues, all having the same molecular formula of C29H42N2O10, were GDM biosynthetic derivatives with one of the three C-C double bonds between C2-C3, C4-C5 and C8-C9 in GDM changed to mono-hydroxylated C-C single bond. The other two novel GDM analogues, having the same molecular formula of C28H38N2O8, were 17(or 12, or 4)-desmethoxylgeldanamycin and 4,5-dihydro-10,11-dehydrate-17-desmethyl-17-hydroxylgeldanamycin, respectively. The known GDM analogue, having the molecular formula of C29H42N2O9, was 4, 5-dihydrogeldanamycin, an intermediate in GDM biosynthesis. The discovery of novel GDM analogues provided us new insights in understanding the biosynthetic details of GDM, and clues of obtaining GDM derivatives by gene-disruption and combinatorial biosynthesis.
