Objective To analyze the clinical features of premature rupture of membrane(PROM)complicated with histologic chorioamnionitis(HCA),and to provide insights for clinical management of such pregnant women and their newborns.Methods A total of 202 cases of PROM pregnant women who gave birth and performed placental pathological examination in the Affiliated Hospital of Southwest Medical University from January to December 2021 were retrospectively analyzed.According to the histopathological results,the pregnant women were divided into HCA group(n=151)and control group(n=51),and the prenatal factors and short-term maternal-fetal pregnancy outcomes of two groups were compared and analyzed.Results The amniotic fluid contamination rate,white blood cell count,neutrophil count and serum amyloid A levels in HCA group were significantly higher than those in control group(P＜0.05).There was a higher incidence of early neonatal septicemia in HCA group than in control group(P＜0.05).Conclusion The risk of early-onset sepsis in neonates with PROM complicated with HCA significantly increases.It is necessary to strengthen the screening and early intervention in such cases.Amniotic fluid contamination and increased maternal infection indicators are associated with the occurrence of HCA,which may has potential value in predicting HCA occurrence.

Objective:To investigate the prospective association of sleep duration with the development of chronic obstructive pulmonary disease (COPD) in adults in Suzhou.Methods:The study used the data of 53 269 participants aged 30-79 years recruited in the baseline survey from 2004 to 2008 and the follow-up until December 31, 2017 of China Kadoorie Biobank (CKB) conducted in Wuzhong District, Suzhou. After excluding participants with airflow limitation, self-reported chronic bronchitis/emphysema/coronary heart disease history at the baseline survey and abnormal or incomplete data, a total of 45 336 participants were included in the final analysis. The association between daily sleep duration and the risk for developing COPD was analyzed by using a Cox proportional hazard regression model, and the hazard ratio ( HR) values and their 95% CI were calculated. The analysis was stratified by age, gender and lifestyle factors, and cross-analysis was conducted according to smoking status and daily sleep duration. Results:The median follow-up time was 11.12 years, with a total of 515 COPD diagnoses in the follow-up. After adjusting for potential confounders, multifactorial Cox proportional hazard regression analysis showed that daily sleep duration ≥10 hours was associated with higher risk for developing COPD ( HR=1.42, 95% CI: 1.03-1.97). The cross analysis showed that excessive daily sleep duration increased the risk for COPD in smokers ( HR=2.49, 95% CI: 1.35-4.59, interaction P<0.001). Conclusion:Longer daily sleep duration (≥10 hours) might increase the risk for COPD in adults in Suzhou, especially in smokers.

With the changes in lifestyle, marriages and childbearing concepts, and population policies in recent years, the proportion of women with advanced maternal age (AMA) in China is rising rapidly. AMA and maternal stress due to advanced age are considered as independent risk factors for maternal mental health and the neurobehavioral development of their offspring. In this paper, we summarized how the glial cell line-derived neurotrophic factor, the hypothalamic-pituitary-adrenal axis, the 5-HT system and the oxytocin affect the maternal mental health and the neurobehavioral development of their offspring, as well as some potential targeted interventions. Interventions currently being developed include artificial supplements, antidepressants, physical exercise, nutrient supplementation, etc., but they have a limited efficacy and a high risk of side effects, yet there is still a lack of specific and systematic interventions. The relevant pathogenesis should continue to be explored in the future research, and hopefully more effective and safe interventions will be given in the near future to improve the mental health of mothers with AMA and the long-term healthy development of their offspring.
