Objective: To explore the relationship between adolescent depressive symptoms, childhood psychological trauma and maternal illness during pregnancy, so as to provide scientific busis for the development of adolescent mental health. Methods: A stratified cluster random sampling method was employed to select 2 092 primary and secondary school students in Wuhan City from January to July 2022. Questionnaires were administered to investigate adolescent depressive symptoms, childhood psychological trauma, and maternal illness during pregnancy. The influencing factors of adolescent depression were analyzed. Results: A total of 139 adolescents reported depressive symptoms. The childhood trauma questionnaire (CTQ) score of the depression group was (57.49± 6.85 ), and the score in adolescents without depression group was (46.28±5.96)( t =21.14, P <0.05). Among the maternal diseases during pregnancy, hypertension accounted for 11.51% , diabetes 9.35%, cholestasis 7.19%, hypothyroidism/hyperthyroidism 7.91% , anemia 9.35% and viral hepatitis 3.60% in depression group, 5.79%, 4.71%, 3.64%, 3.07%, 4.30%, 1.18% in the group without depression, respectively, and the differences were statistically significant ( χ 2=7.35, 5.87, 4.42, 9.28, 7.49, 5.75, P <0.05). The proportion of academic stress in the depressed group and non-depressed group were 61.15% and 46.34%, respectively, and was statistically significant ( χ 2=16.04, P <0.05). Multivariate Logistic regression analysis showed that gestational hypertension ( OR=5.04, 95%CI =2.07-12.24), diabetes mellitus ( OR=4.49, 95%CI =1.85-10.91), anemia ( OR=3.68, 95%CI =1.51-8.94), high academic stress ( OR=3.52, 95%CI =1.45-8.56) and the Childhood Trauma Questionnaire ( OR=4.63, 95%CI = 1.91 -11.26) were the risk factors of depression in adolescents ( P <0.05). Conclusion Adolescent depression may be due to high academic stress, childhood psychological trauma, maternal hypertension, diabetes, thyroid dysfunction and anemia in pregnancy. It is suggested that relevant departments provide appropriate measures to reduce the risk of adolescent depression.

ObjectiveTo explore the pharmacodynamic effects of total flavonoids of Paeonia suffruticosa flower （TFPFs） on rats with hyperuricemia and provide scientific data support for the research and development of therapeutic drugs for hyperuricemia. MethodThe hyperuricemia model was induced by adenine combined with ethambutol in rats. The rats were randomly divided into a blank control group， a model group， two positive control groups （allopurinol at 42 mg·kg^-1 and Tongfengshu tablets at 600 mg·kg^-1）， and high-， medium-， and low-dose TFPFs groups （260， 130， and 65 mg·kg^-1）. The general conditions of rats were observed and recorded， and the body weight was recorded once every 5 days. The 24-hour urine volume， water intake， uric acid （UA）， and urinary protein of rats were determined after the last administration. The kidney index was calculated. The pathological changes in thymus and spleen tissues of rats were observed by hematoxylin-eosin （HE） staining. The serum activities of UA， creatinine （Cr）， blood urea nitrogen （BUN）， malondialdehyde （MDA）， superoxide dismutase （SOD）， and total antioxidant capacity （T-AOC） of rats were determined. The xanthine oxidase （XOD） and adenosine deaminase （ADA） activities in the liver were detected. The content of uric acid transporter 1 （URAT1）， organic anion transporter 1 （OAT1）， and glucose transporter 9 （GLUT9） in the kidney was detected by enzyme-linked immunosorbent assay （ELISA）. ResultCompared with the results in the model group， TFPFs could improve the mental state of rats， increase the body weight（P<0.01）， promote UA excretion（P<0.01）， reduce the content of urinary protein（P<0.05）， relieve renal glomerular atrophy， renal tubular epithelial cell status， and urate crystal deposition in renal tubules， dwindle 24-hour urine volume， water intake， kidney index（P<0.05）， serum levels of UA， Cr， BUN， and MDA（P<0.05，P<0.01）， inhibit the activities of XOD（P<0.05） and ADA（P<0.05，P<0.01）in the liver， diminish the expression of GLUT9 in the renal homogenate（P<0.05）， and increase serum SOD and T-AOC activities as well as OAT1 expression（P<0.01） in the kidney. The pathological changes of thymus and spleen were improved. ConclusionTFPFs possess a protective effect on the kidney of rats with hyperuricemia， which is achieved by promoting uric acid excretion， inhibiting oxidation and the activity of key enzymes in uric acid synthesis， and regulating the expression of uric acid transporters.

Objective: To investigate the safety and efficacy of the Weitan Waifu patch on the postsurgical gastroparesis syndrome (PGS) of gastrointestinal cancer. Methods: The multi-center, double-blind, randomized controlled trial was conducted with superiority design. Patients with PGS of gastrointestinal cancer diagnosed in 4 AAA hospitals and the abdominal symptom manifested as cold syndrome by Chinese local syndrome differentiation were recruited. These patients were randomly divided into two groups according to 1∶1 proportion. Placebo or Weitan Waifu patch was applied in control group or intervention group, respectively, based on the basic treatments, including nutrition support, gastrointestinal decompression, promoting gastric dynamics medicine.Two acupuncture points (Zhongwan and Shenque) were stuck with placebo in control group or patch in treatment group. The intervention course was 14 days or reached the effective standard. Results: From July 15, 2013 to Jun 3, 2015, 128 participants were recruited and 120 eligible cases were included in the full analysis set (FAS), and 60 cases in each group. 88 cases were included in the per-protocol set (PPS), including 45 cases in the treatment group and 43 cases in the control group. In the FAS, the clinical effective rate in the treatment group was 68.3%, significantly superior than 41.7% of the control group (P=0.003). The medium time of effective therapy in the treatment group was 8 days, significantly shorter than 10 days in the control group (P=0.017). In the FAS, 3 adverse events occurred in the treatment group, including mild to moderate decrustation, pruritus and nausea. The incidence rate of adverse events was 5.0% (3/60) and these symptoms were spontaneously remitted after drug withdrawal. No severe adverse events were observed in the control group. There was no significant difference between these two groups (P=0.244). Conclusion: Weitan Waifu patch is a safely and effectively therapeutic method for patients with PGS (cold syndrome) of gastroenterological cancer.

Objective To observe the changes in estrous cycle and vaginal smears in ovarectomized NOD/SCID mice.Methods To continuously observe the estrous cycle time by vaginal smears of NOD/SCID mice in consecutive nine days, twice daily.After ovariectomy, the changes of estrous cycle were observed by vaginal smears for 7 days.Results The estrous cycle in NOD/SCID mice was 4-6 days.Regular estrous mice accounted for 80%.There was no significant correlation between vaginal opening and estrous cycle status.After ovariectomy, the vaginal smears showed characteristics of metestrus or diestrus.Conclusions Vaginal smear cytology can be used to determine the estrous cycle and characteris-tics of NOD/SCID female mice.The ovariectomized operation of NOD/SCID female mice is effective.

The mode of community home-based care with combination of medical care and elderly care is im-portant for promoting healthy aging. But now the services contents provided by community health service agencies were not clear, related system of policies and regulations were imperfect, human resources were insufficient and net-work of service resource was not perfect. All of these factors caused the service cannot met old people medical de-mands and the use for community health services is inadequate. So we should proposesupply-side reform on communi-ty health service to meet the medical demands for old people and even to stimulate new demand.

Objective To investigate the correlations between the soluble form of B7-H3 ( sB7-H3) and the cytokines of IL-17 and IL-8 in serum samples from patients with primary hepatocellular carcino-ma ( HCC) and to evaluate their clinical values for early diagnosis of HCC.Methods Serum samples were collected from 63 patients with HCC and 50 healthy subjects.The expression of sB7-H3, IL-17 and IL-8 in serum samples were detected by ELISA.Receiver operating characteristic ( ROC) curve was generated to an-alyze the diagnostic values of sB7-H3, IL-17 and IL-8 for hepatoma.The logistic regression model was used to predict the probability of hepatoma by using sB7-H3, IL-17 and IL-8 in combination.Results The levels of sB7-H3, IL-17 and IL-8 in serum samples collected from the patients with HCC were significantly higher than those from healthy subjects.A positive correlation was found between the levels of sB7-H3 and IL-17 in serum samples from patients with HCC.No correlation was found between sB7-H3 and IL-8.A negative cor-relation was found between the levels of IL-17 and IL-8 in serum samples from patients with HCC.ROC curve analysis showed that the area under the curve (AUC) of sB7-H3, IL-17 and IL-8 were 0.832, 0.657 and 0.953, respectively, indicating the statistical significance of them for the diagnosis of HCC.The logistic regression showed that the AUC, diagnostic sensitivity and specificity of the regression model PRE in the pre-diction of HCC were 0.960, 91.30% and 94.29%, respectively, which was much better than using the three indicators alone.Conclusion The levels of sB7-H3 were positively correlated to the levels of IL-17 in serum samples from patient with HCC.The logistic regression model of combination of sB7-H3, IL-17 and IL-8 obtained in this study could be used for early clinical diagnosis of HCC in the future.

OBJECTIVETo analyze the opioid binding protein/cell adhesion molecule-like (OPCML) methylation status at different stages of malignant transformation of human bronchial epithelial (16HBE) cells induced by Glycidyl Methacrylate (GMA) and to explore the effect of OPCML methylation in the process of malignant transformation.

METHODSCells were harvested at different stages (the 10th generation, the 20th generation and the 30th generation). To verify the Methylation chip result of OPCML methylation status in the process of malignant transformation, we detected it by methylation-specific-PCR (MSP); Real-time fluorescence Quantitative PCR (qPCR) were applied to measure the gene expression levels of OPCML at different transformed stage, and compared with the control groups (treated with DMSO).

RESULTSBased on the result of methylation chip, the gene of OPCML methylation occurred in all stages, which was consistent to the result of MSP; qPCR showed that the levels of gene expression decreased in the 20th generation and 30th generation.

CONCLUSIONMethylation status of OPCML gene promoter could be considered as a stable and specific biomarker in the transformation process.
