ObjectiveTo analyze the impact of maternal postpartum depression (PPD) at 2 months postpartum on caregiving for infants aged2 to 24 months, and to provide a scientific basis for future maternal and infant healthcare services. MethodsBased on the Shanghai Maternal-Child Pairs Cohort, 1 060 mother-child pairs were selected from those fully participating in follow-up visits at 2, 6, 12, and 24 months postpartum. Pregnancy and childbirth-related information was collected using standardized questionnaire surveys and hospital obstetric and maternity records. The Edinburgh postpartum depression scale was used to assess the maternal postpartum depressive symptoms at 2 months postpartum. At 2, 6, 12, and 24 months postpartum, questionnaire survey was used to evaluate the maternal responsiveness in caregiving and the provision of early learning opportunities for infants. Scores for responsive caregiving and early learning opportunities at 2, 6, 12, and 24 months were grouped based on the 25th percentile (P₂₅) of total scores. The mixed-effects model was used to analyze the longitudinal impact of maternal postpartum depression at 2 months on the caregiving of 2 to 24-month-old infants. ResultsThe longitudinal results from the mixed-effects model did not show an impact of maternal PPD on infant responsive caregiving within 12 months and early learning opportunities within24 months. However, cross-sectional analysis revealed that, compared to the non-PPD group, the risk of low responsive caregiving at 2 months in the PPD group was 93% higher (OR=1.931, 95%CI: 1.113‒3.364, P=0.019). The risks for low provision of early learning opportunities at2 months and 24 months increased by 59% (OR=1.589, 95%CI: 1.082‒2.324, P=0.017) and 60% (OR=1.598, 95%CI:1.120‒2.279, P=0.010), respectively. ConclusionMaternal postpartum depression increases the risk of low responsive caregiving at 2 months, but its long-term effects warrant further research.

Objective:To explore the antiviral activity of the small-molecule compound AM679 in hepatitis B virus (HBV) replication and infection cell models.Methods:The positive regulatory effect of AM679 on EFTUD2 expression was validated by qPCR and Western blotting. HepAD38 and HepG2-NTCP cells were treated with AM679 (0.5, 1, and 2 nmol/L). Negative control, positive control, and AM679 combined with the entecavir group were set up. HBV DNA intra-and extracellularly, as well as the expression levels of intracellular HBV total RNAs and 3.5kb-RNA changes, were detected with qPCR. Hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) levels were measured in the cell supernatant by an enzyme-linked immunosorbent assay (ELISA). The t-test method was used for the statistical analysis of the mean difference between groups.Results:EFTUD2 mRNA and protein expression levels were significantly increased in HepAD38 and HepG2-NTCP cells following AM679 treatment, with a statistically significant difference ( P ?

Objective:To establish the QAMS method for content determination of eight chemical compositions (chlorogenic acid, neochlorogenic acid, cryptochlorogenin acid, isochlorogenic acid A, isochlorogenic acid C, rutin, morroniside and luteolin-7-O-glucoside) from Lonicera alberti Regel. leaves; To verify the feasibility and applicability of this method in quality control for Lonicera alberti Regel. leaves.

Objective:To retrospectively summarize the clinical characteristics and treatment of 49 patients with hyperthyroid cardiopath and to explore the diagnosis and treatment methods of hyperthyroid cardiopathy.Methods:A total of 49 patients with hyperthyroid cardiopath(HC group) who were successfully treated and followed up in the Department of Endocrinology, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, from January 2016 to December 2021 were collected, and 85 cases of Graves′ disease without heart disease were collected as the control group(GD group). The medical history, laboratory tests, and echocardiographic parameters of the two groups were compared. Differences in thyroid and cardiac indicators before and after treatment in the HC group were summarized, along with the dosage of β-receptor blockers used in treating different types of conditions(atrial fibrillation and heart failure.Results:Patients in the HC group were older and had a longer duration of hyperthyroidism than those in the GD group( P<0.001, P=0.002). There were no significant differences in thyroid hormone levels between the two groups except for reverse triiodothyronine(rT 3). Age and rT 3 were independent risk factors of hyperthyroid cardiopathy. rT 3 level was linearly positively correlated with brain natriuretic peptide, systolic pulmonary artery pressure, left artrium diamete (LAD) and left ventricular end-systolic diameter(LVDs; r=0.352, P<0.001; r=0.392, P=0.019; r=0.202, P=0.029; r=0.242, P=0.028). In patients of HC group, free triiodothyronine(FT 3) level returned to normal range after 2.87(1.63, 5.53) months of treatment with radioiodine(41/49) or antithyroid drugs(8/49), while brain natriuretic peptide, LAD, LVDs, and systolic pulmonary artery pressure declined after 5.00(1.25, 8.00) months of treatment. Non-selective β-receptor blockers were used for both hyperthyroid heart failure and atrial fibrillation, and there was no statistically significant difference in dosage[(86.52±47.83)mg vs(88.67±47.19)mg, P>0.05]. Conclusions:rT 3 may be a biomarker of hyperthyroid cardiopath and indicate the severity of hyperthyroidism. β-receptor blockers are crucial in treating patients with hyperthyroidism who develop atrial fibrillation and heart failure.

Objective:To explore the association between socioeconomic status (SES) and overweight/obesity in Yi people in Sichuan province.Methods:A cross-sectional study was conducted in Liangshan Yi Autonomous Prefecture in 2015. Stratified cluster sampling method was used to enroll Yi farmers and rural-to-urban Yi migrants aged 20-80 years. SES was measured by education level, personal annual income, and compound SES index. Unconditional logistic regression models were used to determine the association between SES and overweight/obesity (BMI≥24.0 kg/m 2). Results:1 894 Yi farmers and 1 162 rural-to urban migrants were included in the analysis. After adjustment for age, smoking, drinking and physical activity, compared with illiteracy, OR for farmer males with higher education level (primary or junior school, senior high school or higher) were 1.71 (95 %CI: 1.13-2.58) and 4.15 (95 %CI: 2.10-8.22). Compared with lower income group (<5 000 CNY/y), the higher income group had increased risk ( OR=1.66, 95 %CI: 1.12-2.44). For farmer males with medium and high SES level, the risk of overweight/obesity were 1.65 (95 %CI: 1.02-2.67) and 3.26 (95 %CI: 1.97-5.42) compared with low level of SES. For farmer females, the risk increased with the higher income, with OR as 1.49 (95 %CI: 1.10-2.02). Compared with low SES level, farmer females with medium level of SES was associated with 1.47 (95 %CI: 1.11-1.95) times higher risk of overweight/obesity. In Yi migrants, the association between SES and overweight/obesity was not found. Conclusion:Socioeconomic status was positively associated with overweight/obesity only in Yi farmers.

Objective: To study the effects p-phenylenediamine (PPD) on lung function and health-related quality of life of occupational exposed workers. Methods: This study was based on data from a company that produce hair dye containing PPD in China. Workers who exposed to PPD were selected as the study group, and workers un-exposed to PPD were selected as the control group. Questionnaires on health-related quality of life of workers using the 36-item Short Form Health Survey (SF-36) . Occupational health examination assessment results were tested in Taizhou Cancer Hospital. The lung function test includes forced vital capacity (FVC) , forced expiratory volume in one second (FEV_1.0) , and ratio of FEV_1.0 to FVC (FEV_1.0/FVC) . Results: The difference in systolic blood pressure between the PPD exposed group and the control group was statistically significant (P<0.05) . FVC, FEV_1.0, and FEV_1.0/FVC of the lung function indexes in the exposed group were lower than those in the control group (P<0.05) . In the health-related quality of life, body pain (P=0.002) , general health (P=0.029) , vitality (P=0.038) , and mental health (P=0.003) were lower in the exposed group than in the control group. Conclusion Occupational exposed to PPD may induce hazard to the workers’lung function and may cause detrimental effect on workers’ health-related quality of life.

Objective: To study the effect of p-phenylenediamine (PPD) on liver and kidney function in occupational exposed workers. Methods: Workers in a hair dye production enterprise which used p-phenylenediamine as a raw material for production were selected as the main research population. Then we conducted a questionnaire survey on the basic conditions of workers and conducted occupational health checkups on general health status, liver and kidney function. Occupational health examination assessment results were tested in Taizhou Cancer Hospital. All data was built using EpiData 3.1 software, and statistical analysis was performed using software SPSS 20.0. Results: The liver function indicators including direct bilirubin, prealbumin, total protein, and white protein, globulin, aspartate aminotransferase, glutamyl transpeptidase, and total bilirubin in the workers exposed to high concentration of PPD were at high normal values, and these indicators were significantly different from low PPD concentration group (P<0.05) . The serum creatinine and serum uric acid in the renal function index were significantly higher in workers exposed to PPD than in workers exposed to low concentrations and in the control group (P<0.05) . Conclusion Occupational exposed to PPD may have a hazard to the workers’ liver and kidney function. Long-term occupational exposure to PPD may lead to increased cumulative exposure of workers, which may cause potential chronic liver and kidney damage in occupationally exposed populations.

Objective To compare the pregnancy outcome of mother and infant through the analysis of clinical data of patients with preeclampsia. Methods Clinical data of 237 cases with preeclampsia from March 2013 to March 2014 in the department of obstetrics were analyzed retrospectively. 237 patients with preeclampsia were assigned to two groups according to different gestational weeks, group A (gestational weeks <34 weeks) and group B (gestational weeks ≥34 weeks). Complications as well as the incidence of outcome of perinatal fetus were compared between groups. Results Complications of patients with preeclampsia and incidence of the pregnancy outcome of perinatal fetus in different ges-tational weeks were different. Incidence rate of complications in the two groups was 64.2% and 38.8% respectively;neonatal asphyxia rate was 13.4% and 6.5% respectively; mortality rate of perinatal fetus was 37.3% and 3.6%. Con-clusion Patients with early-onset of preeclampsia have severe conditions, and the prognosis of perinatal fetus is unfa-vorable. Cases of disease should be strictly selected and standardized treatment should be carried out. Conditions of mother and infants should be closely monitored, so as to control disease progression effectively and terminate the preg-nancy at appropriate times.

Objective To investigate the clinical value of prenatal MRI in the diagnosis of fetal bowel obstruction.Methods Pregnant women suspected to have fetal abdominal abnormalities by ultrasonography were suggested to undergo MRI examinations within two days.Scanning sequence included FIESTA,SSFSE and T1WI SPGR sequence,with field of view focused on the fetal abdomen.After the final diagnoses of the cases were obtained by induced labor pathological examination or postpartum imaging or operation,the imaging data and the clinical data were reviewed and analyzed retrospectively.Results A total of 23 cases with bowel obstruction were included in the study.Four fetuses with duodenal atresia showed low T1 signal,high T2 signal characterized by double-bubble sign on MRI.There were 10 fetuses with jejunoileal atresia,showing bowel dilatation and hyperintense micro-colon on T1WI.Five cases of them depicted expansion of the terminal ileum with high T1 meconium signal.One each fetus had colonic atresia,intestinal malrotation with double-bubble and whirl sign.Annular pancreas with double-bubble sign and pressure trace of the bracket shape was detected in 3 fetuses.Meconium peritonitis was present in 4 fetuses,with 2 of them showing dilatation of intestine,ascites and pseudocysts.Conclusions According to the signal characteristics of amniotic fluid and meconium in the gastrointestinal tract on MRI,the obstructive level and development status of the distal bowel can be determined with MRI.It can provide additional information to ultrasonography,which brings clinical significance to prenatal diagnosis and intrapartum surgical operation.
