Objective:To evaluate the effect of maternal depressed mood at pregnancy and postpartum on the risk of emotional or behavioral disorders of offspring by meta-analysis. Methods:The following Mesh words and free words were searched in 7 online databases, including the PubMed, Embase, Web of Knowledge, PsycINFO, Cochrane, WanFang databases and China National Knowledge Infrastructure from January 1, 2000 to October 31, 2020: " maternal" AND " depression" AND " child OR offspring" AND " neuropsychology" . According to the inclusion and exclusion criteria, case-control and cohort studies reporting the effect of maternal depressed mood during pregnancy or postpartum on the risk of emotional or behavioral disorders of offspring were reviewed. Meta-analysis was performed by RevMan 5.3. Results:Fourteen studies involving 3 914 in the case group and 17 016 in the control group were included.Children whose mother with depressed mood during pregnancy or postpartum had 2.03 times risk of emotional or behavioral disorders than those whose mothers without depressed mood ( OR=2.03, 95% CI: 1.55-2.65). Both depressed mood at pregnancy and postpartum could increase the incidence of emotional or behavioral disorders in children, but there was no significant difference between these two periods ( Z=-0.371, 95% CI: 0.796-1.168). Moreover, the effect of maternal depressed mood on emotional or behavioral disorders in offspring could last to the preschool and school period, and the children in the school period may have higher incidence of emotional or behavioral disorders than those during the preschool period ( Z=-2.340, 95% CI: 0.643-0.962). Conclusions:Maternal depressed mood can increase the incidence of emotional or behavioral disorders in offspring, which are long-lasting and do not decrease with age.

Objective To evaluate the clinical efficacy of early diagnosis by contrast-enhanced ultrasound (CEUS) combined with mesenchymal stem cell (MSC) therapy in the treatment of biliary ischemia after liver transplantation. Methods Clinical data of 9 recipients presenting with biliary ischemia detected by CEUS within 4 weeks after liver transplantation and diagnosed with non-anastomotic biliary stricture (NAS) within postoperative 1 year were retrospectively analyzed. In the conventional treatment group, 4 recipients were treated with conventional treatment including liver protection, cholagogic therapy and interventional therapy. In MSC treatment group, 5 recipients received intravenous infusion of MSC at 1, 2, 4, 8, 12 and 16 weeks after biliary ischemia detected by CEUS on the basis of conventional therapy. The interventional treatment and clinical prognosis within 1 year after liver transplantation were analyzed between two groups. Results Two recipients in the MSC treatment group required interventional therapy, which was initially given at 7-9 months after liver transplantation for 1-2 times. All recipients in the conventional treatment group required interventional therapy, which was initially delivered at postoperative 1-3 months for 2-6 times, earlier than that in the MSC treatment group. Within 1 year following liver transplantation, diffuse bile duct injury occurred in 2 recipients in MSC treatment group, and no graft dysfunction was observed. In the conventional treatment group, all recipients developed diffuse bile duct injury, and 2 recipients presented with graft dysfunction. Conclusions Early diagnosis of biliary ischemia after liver transplantation by CEUS combined with MSC therapy may delay and reduce the requirement of interventional therapy for NAS, and also improve clinical prognosis of the recipients.

Objective:To identify the association of sex hormone and sex hormone-binding globulin (SHBG) levels in patients with Graves′ disease.Methods:Between December 2017 and July 2019, 152 patients with Graves′ disease were enrolled in the Department of Endocrinology and Metabolism of Zhongshan Hospital, Fudan University. Parameters such as height, weight, thyroid function, sex hormone, fasting blood glucose, insulin, C-peptide, glycosylated albumin, HbA 1C, and liver function were collected. The associations between SHBG and bioclinical characteristics were analyzed. Results:The glycosylated albumin level was negatively associated with SHBG in all subjects ( β=-0.308, P<0.01), while this association was not significant after the adjustment for thyroid hormones. Male patients had significantly lower SHBG level than female patients ( P<0.01). In male patients, SHBG was associated with luteinizing hormone ( r=0.465, P<0.01), estradiol ( r=0.629, P<0.01), testosterone ( r=0.786, P<0.01). While in female patients, SHBG was also associated with testosterone ( r=0.191, P<0.05). In multivariate linear regression analysis, estradiol was independently associated with SHBG ( β=0.329, P<0.01) in male subjects. Conclusion:The hypogonadism and infertility in Graves′ disease patients could partially be attributed to the association between SHBG and Graves′ disease.

Objective To assess the effect of psychological group on improving the learning attitude of interns in the pediatric clinical practice.Methods This study included 67 medical students who enrolled during 2012 to 2013 and had done the clinical pediatrics in the Second Affiliated Hospital of Shantou University Medical College.The students carried out pediatric clinical practice as requested.Based on the practice of pediatric practice,the psychological group counseling was conducted by voluntary participation.Each psychological group consisted of 5 or 6 students and performed once a week.Each time of psychological group lasted for 1.5 hours and 6 times in total.The students were divided into intervention group and non-intervention group according to whether they participated in psychological group.Each student filled in the Pediatric Clinical Internship Attitude Assessment Form and the College Student Personality Questionnaire at the first week and the last week of pediatric clinical practice.SPSS 17.0 was applied to conduct Chi square test and t test.Results There were 33 students in the intervention group and 40 students in the non-intervention group.The effective rate of questionnaires for intervention group and non-intervention group were 100％ and 85％,respectively.The mental state of pediatric interns between two groups was not different before and after the pediatric clinical practice (P＞0.05).Before pediatric clinical practice,the learning attitude score between two groups was not different [(83.82 ± 8.39) vs.(84.39 ± 8.29),t=-0.28,P=0.781].After pediatric clinical practice,the learning attitude score of pediatric interns who used psychological group teaching model was better than that of pediatric interns who used traditional teaching model [(88.91 ± 7.40) vs.(75.03 ± 11.19),t=-5.969,P=0.000].Conclusion Psychological group can help medical students to develop empathy toward sick children and their parents,and then improve their learning attitude in pediatric practice.The results of this study can provide a preliminary basis for the popularization of psychological group in the whole process of medical internship.

Objective:To investigate the influence of propofol combined with sevoflurane anesthesia on nitric oxide/endothelin-1 ratio in the patients with hepatic lobectomy. Methods:Totally 84 patients with hepatic lobectomy were divided into two groups by the digital random method. Among them,42 patients received propofol combined with sevoflurane anesthesia as the observation group,and another 42 patients received midazolam anesthesia as the control group. Nitric oxide,endothelin-1,liver function indices(AST,ALT) and inflammatory factors (IL-1,IL-10,TNF-α) were detected respectively before hepatic portal occlusion,after hepatic portal occlu-sion and on postoperative third day. Results: Before hepatic portal occlusion, there were no significant differences between the two groups in above indicators (P >0.05). After hepatic portal occlusion, NO and IL-10 decreased significantly, while endothelin-1, AST,ALT,IL-1 and TNF-α increased significantly in the two groups.The differences between the two groups were statistically signifi-cant (P<0.01). All indices at postoperative 3 d in two groups recovered to the level before hepatic portal occlusion.Conclusion:Propofol combined with sevoflurane anesthesia contributes to adjusting nitric oxide/endothelin-1 ratio in the patients with hepatic lobec-tomy,which can improve liver function and inhibit the release of inflammatory cytokines.

OBJECTIVETo investigate the effect of CD59 gene inhibition mediated by RNA interference on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) GLC-P cells in vitro.

METHODSRecombinant plasmids for RNA interference of CD59 gene were constructed and transfected into GLC-P cells via lipofectamine 2000. The stably transfected cells were examined with real-time RT-PCR, MTT assay and enzyme-linked immunosorbent assay to investigate the changes in cell proliferation and apoptosis.

RESULTSCompared with the control cells, the cells transfected with CD59-siRNA showed significantly decreased expression levels of CD59 mRNA (P<0.05) and significantly inhibited cell proliferation.

CONCLUSIONCD59 gene is highly expressed in NSCLC and RNA interference-mediated CD59 silencing can strongly inhibit the proliferation and induce apoptosis in GLC-P cells, which shed light on a potentially new target for targeted gene therapy of NSCLC.

OBJECTIVETo investigate the presence of miRNA-144 in the saliva of patients with esophageal cancer and its value for early diagnosis of esophageal cancer.

METHODSSaliva samples were collected form patients with esophageal cancer admitted in the Fourth Affiliated Hospital of Jinan University and the First Affiliated Hospital of Guangzhou Medical College between January, 2011 and May, 2013, with saliva samples from 50 middle-aged healthy volunteers matched for age and gender ratio as the control group. The contents of miRNA-144 in the samples were detected with RT-PCR.

RESULTSThe levels of miRNA-144 in both the whole saliva and saliva supernatant were significantly higher in esophageal cancer group than in the control group (P<0.05). In the whole saliva, the cut-off point of miRNA-144 was ≥100, with a sensitivity of 74.6% and a specificity of 92.0% for esophageal cancer diagnosis (Az=0.865); in saliva supernatant, the cut-off point was ≥20 with a sensitivity of 53.7% and a specificity of 94.0% (Az=0.754), suggesting a moderate diagnostic value of miRNA-144 in whole saliva and saliva supernatant.

CONCLUSIONmiRNA-144 is highly expressed in the saliva of patients with esophageal cancer and can be used as a genetic marker for early diagnosis of esophageal cancer.
