Objective:To explore the clinical effects and impacts of different delivery methods on pregnancy outcomes in preterm women with scarred uterus re-pregnancy after prior cesarean section.Methods:The clinical data of 431 pregnant women with scar uterus re-pregnancy and premature delivery admitted to Jiaxing Maternal and Child Health Hospital from January 2017 to December 2021 were retrospectively analyzed. According to the mode of delivery, 107 patients who were delivered through vagina were included in the study group and 324 patients undergoing cesarean section were selected as the control group. Amount of postpartum bleeding, incidence of uterine rupture, and hospital stay were compared between two groups. Incidence of neonatal asphyxia and 1-, 5-, and 10-minute Apgar scores were also compared between the two groups.Results:Compared with the control group, postpartum bleeding volume and hospital stay were significantly lower in the study group [(232.31 ± 73.82) mL vs. (354.27 ± 89.49) mL, (4.32 ± 0.61) days vs. (6.23 ± 0.94) days; t = 12.74, 19.69, P < 0.05). There was no significant difference in the incidence of uterine rupture ( P > 0.05), incidence of neonatal asphyxia ( P > 0.05), and 1-, 5-, and 10-minute Apgar scores ( P > 0.05) between the two groups. Conclusion:For premature delivery women with scarred uterus after prior cesarean section, both cesarean section and vaginal delivery can be chosen for successful delivery. However, vaginal delivery has less postpartum bleeding and shorter hospital stay, which is a feasible and safe delivery method. Vaginal delivery is encouraged for re-pregnancy after cesarean section.

Objective:To investigate the efficacy of magnesium sulfate plus aspirin in the treatment of pregnancy-induced hypertension and its effect on placental hypoxia-induced factor-1α (HIF-1α) levels.Methods:This is a case-control study. The clinical data were collected from 96 patients with gestational hypertension who were admitted to Jiaxing Maternity and Child Health Care Hospital between January 2019 and January 2023. These patients were divided into a control group and a study group, with 48 patients in each group, according to different treatment methods. The control group received magnesium sulfate treatment, whereas the study group was treated with magnesium sulfate combined with aspirin. Both groups were treated for 14 days. The clinical efficacy of the two groups was compared. Pre- and post-treatment blood pressure, placental HIF-1α levels, and endothelin levels were compared between the two groups. The incidence of adverse reactions and adverse pregnancy outcomes were also compared between the two groups.Results:The response rate in the study group was significantly higher compared with that in the control group, with 93.8% (45/48) versus 79.2% (38/48), respectively ( χ2 = 4.36, P < 0.05). Following treatment, both diastolic and systolic blood pressure levels in the study group were significantly lower than those in the control group ( t = 5.70, 7.33, both P < 0.05). Placental HIF-1α and endothelin levels in the study group were (41.03 ± 6.95) μg/L and (93.37 ± 8.29) ng/L, respectively, which were significantly lower than those in the control group [(82.97 ± 8.86) μg/L, (124.96 ± 9.32) ng/L, t = 17.55, 25.80, both P < 0.001]. The incidences of adverse reactions and unfavorable pregnancy outcomes in the study group were 12.5% (6/48) and 10.4% (5/48), respectively. These were significantly lower compared with those in the control group, which were 31.3% (15/48) and 27.1% (13/48), respectively ( χ2 = 4.94, 4.38, both P < 0.05). Conclusion:Magnesium sulfate combined with aspirin is highly effective in treating pregnancy-induced hypertension. This combined therapy can effectively lower patients' diastolic and systolic blood pressures, as well as placental HIF-1α and endothelin levels. It can obviously reduce the incidences of adverse reactions and unfavorable pregnancy outcomes.

ObjectiveTo investigate the acceptance and influencing factors of manual hyperinflation (MIH) in patients with open sputum suction after tracheotomy, so as to provide reference for improving the acceptance of MIH for patients. MethodsBy convenience sampling, 140 patients with tracheotomy on open suction in Affiliated Hangzhou First People＇s Hospital, Zhejiang University School of Medicine from October 2016 to September 2018 were selected as participants in the study and the Self-Designed Questionnaire was used to study the acceptance towards MIH of the patients. Univariate analysis and Logistics regression analysis were conducted to analyze the influencing factors of the acceptance of patients on MIH. A total of 140 questionnaires were distributed, and 134 valid ones were collected. ResultsUnivariate analysis showed that there were statistical difference in age, gender, family support, duration of tracheotomy, whether the medical staff had explained the relevant knowledge of MIH, and whether the patients had experienced MIH on patients＇acceptance of MIH (P＜ 0.05). The above 6 statistically significant factors were analyzed by multivariate Logistic regression and the results showed that age, gender, duration of tracheotomy, whether the patients had experienced MIH before were the influencing factors of the patients＇ acceptance on MIH(P＜ 0.05). ConclusionsAge, gender, duration of tracheotomy, whether or not the patents have experienced MIH are independent impact factors for the patients＇ acceptance of MIH and the above factors can be the cut-in points of explanation and education in the process of MIH,so as to improve the patients＇ acceptance of MIH and promote recovery.

Objective To investigate the effect of Osthole on memory function of sleep deprivation(SD) mice. Methods Forty-eight male mice were randomly divided into 4 groups;normal control group(NC group ), large platform control group(TC group),sleep deprivation group(M group)and Osthole group(Ost group). The model of SD in mice was estabished by using improved multi platform method. The ability of learning and memory was tested by using Morris water maze test and pathological changes of hippocampal neurons in mice were observed by HE staining. The serum,hippcampus malondialdehyde(MDA)contents and superoxide dismutase(SOD)activity, so as the hippocampus No content,were detected. Results Compared with NC group and TC group,the escape la-tency of M group increased significiantly and the number of crossing platform decreased significantly. There were in-creased levels hippocampus tissue,serum MDA level,hippocampal SOD activity and NO content. After supplemen-tation of Osthole,the escape latency significantly shortened in mice. The number of crossing platform was increased while the contents of MDA both in hippocampus and serum were decreased,and the SOD activity in hippocampus re-turned to normal. However,the level of NO in hippocampus was not decreased. Conclusion Osthole can protect the memory function of SD mice by reducing the the damage of hippocampal neurons through antioxidant stress.
