Objective: To investigate the implementation of sex education and its influencing factors among preschool teachers in Luzhou City, Sichuan Province, so as to provide insights into promoting the development of sex education, physical and mental health for preschool children. Methods: In January 2022, preschool teachers were sampled in 24 kindergartens in Longmatan District, Naxi District and Hejiang County of Luzhou City using the stratified random cluster sampling method. Demographic information, knowledge, attitudes, implementation of sex education, as well as difficulties, support, and needs in implementing sex education among preschool teachers were collected through questionnaire surveys. Factors affecting practice of sex education by preschool teachers were analyzed using a multivariable logistic regression model. Results: A total of 461 preschool teachers were included, including 456 females (98.92%), and had a median age of 28.00 (interquartile range, 9.50) years. The proportions of preschool teachers with good and pass of knowledge about sex education for preschool children were 10.20% and 57.48%, respectively. The proportions of preschool teachers with positive and general attitudes towards sex education were 28.20% and 36.44%, respectively. A total of 343 preschool teachers had implemented sex education (74.40%). A lack of a relaxed social environment was the main difficulty in carrying out sex education for preschool children (76.14%), while support from parents of preschool children was the primary need for conducting sex education activities (75.27%). Multivariable logistic regression analysis showed that age (>30 years, OR=2.218, 95%CI: 1.256-3.917), kindergarten type (public, OR=2.101, 95%CI: 1.253-3.524), attitude towards sex education (positive, OR=2.083, 95%CI: 1.036-4.187), participation in activities related to sex education (OR=6.355, 95%CI: 3.362-12.015), and communication with parents about sex education (OR=5.399, 95%CI: 3.152-9.248) were influencing factors for practice of sex education by preschool teachers. Conclusions The main difficulty in the practice of sex education for preschool children by preschool teachers in Luzhou City is a lack of a relaxed social environment, and there is a high demand for support from parents. Age, kindergarten type, attitude towards sex education, participation in activities related to sex education, and communication with parents about sex education are associated factors.

OBJECTIVETo study the molecular mechanism of Yangjing Zhongyu Decoction (YZD) n-butanol extracts (ZDC) and ethyl acetate extracts (YSYZ) in reducing androgen in porcine granulose cells by mitogen-activated protein kinase (MAPK) pathway.

METHODSPorcine granulose cells were isolated and cultured. They were inoculated by MAPK inhibitor PD98059 at different concentrations, and then they were divided into the blank control group (0), 1, 3, 10, and 25 micromol/L groups. After 24-h culture the cytochrome P450c17a (CYP17) mRNA expression level was detected using Real-time fluorescent quantitative PCR. Contents of androgen (testosterone) in the supernate were detected using RIA and optimal PD98059 concentration screened. After intervened by 10 micromol/L PD98059 for 24 h, the culture solution was intervened by effective ingredients of with or without YZD or YSYZ at various concentrations (0, 1 , 5, 25, 50 mg/mL) at various time points (3, 6, 18, 24 h). Expression levels of p-ERK1/2, c-Fos and CYP17 were detected by Western blot. Testosterone content in the supernate was determined by radioimmunoassay (RIA).

RESULTSTen pLmol/L PD98059 could obviously decrease p-ERK1/2 protein expression and increase CYP17 mRMA expression, and elevate testosterone content in the supernate (P < 0.05). ZDC and YSYZ at 25 ng/mL could increase p-ERK1/2 protein expression and c-Fos levels, and reduce CYP17 protein expression, and lower testosterone content in the supernate after 6-h intervention (P < 0.01).

CONCLUSIONEffective ingredients of YZD could reduce androgen production in porcine granulose cells through increasing activities of MAPK.

OBJECTIVETo study the relationship between serum load level of HBV-DNA and therapeutic effect of oxymatrine in patients with chronic hepatitis B.

METHODSForty-four patients of chronic hepatitis B were divided into two groups, the treated group was treated with oxymatrine 0.4 g/d by intramuscular injection for 3 months, the control group was treated with some liver protecting agents to estimate the therapeutic effect. The serum level of HBV-DNA was determined by quantitative polymerase chain reaction (PCR) before and after treatment.

RESULTSThe seroconversion rate of HBV-DNA and HBeAg in the treated group was 43.47% and 43.47% respectively, which was obviously better than those in the control group respectively (P < 0.05), the quantity of HBV-DNA decreased after treatment from 10(6.83 +/- 1.27) copy/ml to 10(3.35 +/- 3.08) copy/ml. Among them, in patient with HBeAg negative conversion, the pretreatment quantity of HBV-DNA was 10(6.30 +/- 1.42) copy/ml, while in those with no HBeAg negative conversion, it was 10(7.23 +/- 1.23) copy/ml, the difference was significant.

CONCLUSIONOxymatrine is effective in treating chronic hepatitis B. The therapeutic effect is better for patients with lower quantity of serum HBV-DNA.
