Résumé
Abstract We aimed to develop a prognostic model for primary pontine hemorrhage (PPH) patients and validate the predictive value of the model for a good prognosis at 90 days. A total of 254 PPH patients were included for screening of the independent predictors of prognosis, and data were analyzed by univariate and multivariable logistic regression tests. The cases were then divided into training cohort (n=219) and validation cohort (n=35) based on the two centers. A nomogram was developed using independent predictors from the training cohort to predict the 90-day good outcome and was validated from the validation cohort. Glasgow Coma Scale score, normalized pixels (used to describe bleeding volume), and mechanical ventilation were significant predictors of a good outcome of PPH at 90 days in the training cohort (all P<0.05). The U test showed no statistical difference (P=0.892) between the training cohort and the validation cohort, suggesting the model fitted well. The new model showed good discrimination (area under the curve=0.833). The decision curve analysis of the nomogram of the training cohort indicated a great net benefit. The PPH nomogram comprising the Glasgow Coma Scale score, normalized pixels, and mechanical ventilation may facilitate predicting a 90-day good outcome.
Résumé
Abstract@#School-based sexuality education plays a vital role in the healthy development of children and adolescents. At present, China has issued a series of laws, regulations and policy documents to support school-based sexuality education, but the development of school-based sexuality education in China still faces challenges such as negative attittude, lack of class hours, professional teachers, teaching materials, as well as effect evaluation and sensitive nature. Experience in school-based education in many countries demonstrated that the research and development of localized comprehensive sexuality education guidance on school-based education is effective in promoting school-based sexuality education. In 2018, with the support of UNESCO and UNFPA, Lab of Comprehensive Sexuality Education for Children of Beijing Normal University, inititated the "Research and Development of Comprehensive Sexuality Education Guidance" project, aiming to develop a local "Comprehensive Sexuality Education Guidance",and to support and promote the school-based sexuality education in China.
Résumé
Abstract@#From 1949 to 2020, school-based sexuality education in China gradually established its legal status and received more policy support. During these 70 years of development, the attitudes of Chinese government departments towards school-based sexuality education, the direction of policy advocacy, school age of sexuality education and the development of local sexuality education have changed substantially. This editorial describes characteristics of the development of school-based sexuality education policy in China, aiming to depict development paths of school-based sexuality education policy in China so far, and provides inspiration for more policy support for schoolbased sexuality education in China.
Résumé
Abstract@#From 1949 to 2020, research in the field of school-based sexuality education in China witnessed substantial development with the support of relevant policies. With the continued investment of social resources, school-based sexuality education has gradually been accepted and recognized by the public. During those 70 years of development, government departments, academic institutions, and social organizations were all exploring and looking for localized programs suitable for the development of school-based sexuality education in China. This paper overviewed characteristics of the development of school-based sexuality education research as well as of social resource support in China, in order to outline the development context of school-based sexuality education research, and to bring inspiration to the future development of school-based sexuality education research in China.

Objective@#To understand the current situation of sexual knowledge, attitudes and behaviors of young children in kindergarten, based on the framework of comprehensive sexuality education.@*Methods@#Totally 354 children between the ages of 3-6 from two kindergartens in Changping District, Beijing, participated in one-to-one interviews. There were 164 girls and 190 boys.@*Results@#In the dimension of physical development, no child knew the scientific name of reproductive organs. In the dimension of social emotion, 44.07% of children could express love to their friends, and 40.68% of children could express their refusal when they were unwilling. In the dimension of sexual health, well-being and sexual rights，81.92% of children knew that they couldn t touch other people s genitals, and 54.80% of children could at least name one way to protect themselves when facing sexual abuse. In the dimension of gender equality, 33.62% and 28.53%of children had gender stereotypes in toy selection and career choice, 66.38% of children thought that boys are as smart as girls. In the dimension of pregnancy and birth，78.53% of children knew where babies come from and 26.27% of children think parenthood doesn t directly lead to happiness. Sexual knowledge, attitudes and behaviors of children had statistically significant difference in different grades（P<0.05).@*Conclusion@#Children already have good understanding about pregnancy, childbirth and prevention of sexual abuse. In the future, sexuality education in school and family need to promote physical cognition and gender equality education.
Résumé
Objective@#To provide empirical evidence on the effectiveness of comprehensive sexuality education (CSE) on sexual knowledge and sexual attitudes improvement among college students.@*Methods@#Sexual knowledge and attitudes questionnaire survey was implemented among college students in Beijing, who later received the CSE for a full semester. Sexual knowledge and attitude were evaluated after intervention and were compared with control students.@*Results@#The average score of sexual knowledge was low among college students in Beijing. Most students held neutral attitudes towards "AIDS community" and "masturbation behavior" and positive attitudes towards "LGBT"(58.85%, 68.75%, 61.98%). Compared with the control group, after one semester of CSE curriculum intervention, the average scores of the five dimensions on sexual knowledge in the intervention group was significantly improved(11.79±1.16, 9.36±1.23, 4.84±0.88, 4.91±1.00, 5.35±1.03)(t=11.25, 15.74, 10.37, 5.59, 8.17, P<0.01), and the attitudes towards "sexual minorities", "AIDS communities" and "masturbation behavior" were also significantly improved(30.59±3.91, 17.70±3.41, 10.12±2.17)(t=5.16, 5.83, 2.97, P<0.01).@*Conclusion@#College students’ knowledge of sexuality is not optimistic. The attention to proper sexual attitudes is in great need. Systematic and comprehensive sexuality education curriculum could improve college students’ sexual knowledge and attitudes.
Résumé
Objective@#To analyze the influence of sexuality education on primary school students’ attitude towards homosexuality, and provide practical teaching evidence of intervening campus bullying based on sexual orientation.@*Methods@#A primary school offering school-based sexuality education curriculums in Beijing was selected as an experimental school, another school with similar location, nature and scale, quality of teachers and teaching environment was selected as a control school. The graduates in experimental school received 6 years of sexuality education in grade 1 to grade 6 of primary school. A survey was conducted in Jun. 2018 among all the graduates in grade 6 of the two schools through an attitude scale on homosexuality adopting cluster sampling.@*Results@#The scores of attitude towards homosexuality in experimental school and control school were (42.85±15.46) and (60.17±12.54) respectively, with significantly statistical difference(t=-9.47, P<0.01). There were interaction effects on attitudes of primary school students towards homosexuality between gender and experience of sexuality education (P<0.05). There was no significant difference in attitude towards homosexuality between male and female students in control school(t=0.58, P>0.05), but in experimental school, the attitude scores of male and female students respectively were (47.64±14.31) and (38.13±15.19), with significantly statistical difference(t=3.47, P<0.01). There was no significant difference in attitude towards different sexual orientation between experimental school students and control school students(t=0.10，1.53，P>0.05).@*Conclusion@#Sexuality education curriculum can help improve attitude towards homosexuality of primary school students, which has better intervention effects on female students than male students, attitudinal difference in gay and lesbian has not formed in primary school students.
