    Abstract Owing to the frequent accidents in primary and secondary schools (PSS) in China in the past decades, a systematic analysis of indicators influencing safety risks in PSS is critical to identifying preventive measures. A two-hierarchy structure of indicators was identified by analyzing various cases, intensive interviews, and related previous literature. A combination of the analytic hierarchy process and the entropy weight method was developed to synthetically assess the primary and secondary risk indicators through a case study of Ma Shan School in China. The results are as follows: (1) the primary risk indicators, namely, natural disasters, public health, facility safety, accidental injury, public security, school bullying, and individual health constitute the evaluation framework of the safety risks in PSS. (2) Public health risks and accidental injury risks are the most critical factors that should be prioritized. In addition to providing academic implications, several managerial implications are proposed for these stakeholders to reduce the safety risks in PSS.

    Abstract Objective. Hypertensive disorders of pregnancy (HDP) can cause serious prenatal and postnatal complications and is a threat to maternal and fetal health. To offer guidance for clinical decisions, we systematically reviewed the effects of misoprostol on induction of labour in HDP patients. Methods. PubMed, Web of Science, Embase, CNKI, and Wanfang databases were searched for relevant literature from 2010 to 2020. Subsequently, a meta-analysis was performed to compare the effective rate of induction of labour and reducing postpartum hemorrhage (PPH) between the intervention group (n = 544, misoprostol) and the control group (n = 543, oxytocin). Results. A total of 10 studies with 1087 patients were included. The 10 studies compared the effective rate of induction of labour between the two groups and confirmed that the effective rate in the intervention group was significantly higher than that in the control group (OR = 4.37; 95% CI: 2.73, 7.00). Seven studies compared PPH between the groups and showed that it was significantly reduced in the intervention group compared to the control group (SMD = −1.32; 95% CI: −2.05, −0.59; P<0.0001). Conclusion. Misoprostol has a high effective rate of induction of labour in HDP patients and is an effective uterotonic agent in reducing PPH. This meta-analysis provides clinicians with meaningful information to help them make evidence-based decisions.

    Abstract Background/aims: To detect the expression of the TRPC3 channel protein in the tissues of women experiencing preterm labor and investigate its interaction with T lymphocytes, providing a theoretical basis for the clinical prevention of threatened preterm labor and the development of drug-targeted therapy.
    Methods: Forty-seven women experiencing preterm labor and 47 women experiencing normal full-term labor were included in this study. All included women underwent delivery via cesarean section; uterine samples were obtained at delivery. The expression of TRPC3 in uterine tissue was detected by immunohistochemistry, real-time quantitative reverse transcription-PCR, and western blot assay. Activation of T lymphocytes in peripheral blood and uterine tissue were detected by flow cytometry. A TRPC3-/- mouse model of inflammation-induced preterm labor was established; expression of TRPC3, Cav3.1, and Cav3.2 were analyzed in mouse uterine tissue. Activation of T lymphocytes in female mouse and human peripheral blood samples was determined using flow cytometry.
    Results: In women experiencing preterm labor, expression of TRPC3 and the Cav3.1 and Cav3.2 proteins was significantly increased; in addition, the percentage of CD3+, CD4+, and CD8+ T cells in peripheral blood was significantly decreased. TRPC3 knockout significantly delayed the occurrence of preterm labor in mice. The muscle tension of ex vivo uterine strips was lower, Cav3.1 and Cav3.2 protein expression was lower, and the percentage of CD8+ T lymphocytes was significantly increased in wild-type mice subjected to an inflammation-induced preterm labor than in wild-type mice experiencing normal full-term labor.
    Conclusion: TRPC3 is closely related to the initiation of labor. TRPC3 relies on Cav3.1 and Cav3.2 proteins to inhibit inflammation-induced preterm labor by inhibiting the activation of T cells, in particular CD8+ T lymphocytes.

    Abstract Objective(s): We aimed to investigate the influence of transient receptor potential channel 3 (TRPC3) on lipopolysaccharide-induced (LPS) preterm delivery mice. Materials and Methods: Mice were randomly assigned to the four groups: an unpregnant group, a mid-pregnancy group (E15), a term delivery group, and an LPS-induced preterm delivery group (intraperitoneal injection LPS at 15 days). Uterine smooth muscles were obtained through caesarean section; TRPC3 expression was measured by real-time PCR, western blotting, and immunohistochemistry. A specific inhibitor of TRPC3 (SKF96365) was injected into the LPS-induced preterm delivery group to determine whether the delivery interval was prolonged. Results: TRPC3 was primarily expressed in the uterine smooth muscle layer. In addition, the LPS-induced preterm delivery group had an obviously higher expression level of TRPC3 mRNA and protein compared with the unpregnant and E15 groups, which were close to term delivery. More importantly, SKF96365 prolongs the delivery interval of LPS-induced preterm delivery mice. Conclusion: Enhanced expression of TRPC3 may be associated with LPS-induced preterm delivery in mice. The specific inhibitor of TRPC3 (SKF96365) may be helpful for clinical treatment of preterm delivery.

    Abstract High levels of aldehyde dehydrogenase (ALDH) activity have been detected in various progenitor and stem cells. Thus, Aldefluor fluorescence, which represents precisely the ALDH activity, has been widely used for the identification, evaluation, and isolation of stem and progenitor cells. Recently, ALDH activity was detected in embryonic and adult mouse pancreas, specifically in adult centroacinar and terminal duct cells supposed to harbor endocrine and exocrine progenitor cells in the adult pancreas. Nevertheless, ALDH activity and aldeflour fluorescence have not been examined in beta cells. Here, we report a dynamic increase in the number of aldeflour+ beta cells during pregnancy. Interestingly, nearly all these aldeflour+ beta cells are positive for Ki-67, suggesting that they are in an active cell cycle (G1, S and M phases). To determine precisely at which phase beta cells activate ALDH activity and thus become aldeflour+, we co-stained insulin with additional proliferation markers, phosphohistone3 (PHH3, a marker for M-phase proliferating cells) and Bromodeoxyuridine (BrdU, a marker for S-phase proliferating cells). Our data show little aldeflour+ beta cells that were positive for either PHH3, or BrdU, suggesting that beta cells activate ALDH and become Aldefluor+ when they enter G1-phase of active cell cycle, but may downregulate ALDH when they leave G1-phase and enter S phase. Our data thus reveal a potential change in ALDH activity of proliferating beta cells during pregnancy, which provides a novel method for isolation and analysis of proliferating beta cells. Moreover, our data also suggest that caution needs to be taken on interpretation of Aldefluor lineage-tracing data in pancreas.
