This study aimed to evaluate the effects of in-utero exposure to HIV and ART on pregnancy outcome and early growth of children. This cohort study enrolled 802 HIV-infected pregnant women between October 2009 and May 2018 in Guangzhou, China. The women were assigned to receive combination ART (cART) or mono/dual ART or no treatment. The primary outcomes were the combined endpoints of any adverse pregnancy outcome [including ectopic pregnancy, spontaneous abortion, stillbirth, preterm birth, small for gestational age (SGA)] and adverse early growth outcome (including infant death, HIV infection of mother-to-child transmission, and underweight, wasting and stunting of infants at 4 weeks of age). Adverse pregnancy outcomes occurred in 202 (35.1%) of all enrolled HIV-infected women, and 121 (31.3%) of all infants exhibited adverse effects on early growth at 4 weeks of age. The rates of adverse pregnancy outcomes, spontaneous abortion, ectopic pregnancy, stillbirth, infant death and perinatal HIV infection were higher among women not receiving ART, compared to those treated with cART or mono/dual ART (P < 0.05). However, women treated with cART had a higher rate of SGA, compared to untreated women (P < 0.05). No differences in early infant growth were observed among the different treatment regimens. Our findings underscore the essentiality of prioritizing HIV-positive pregnant women for ART, as even mono/dual ART available in resource-limited countries could improve pregnancy outcomes and infant survival.

Objective: To understand the prevalence of asthma and its variation over time in children aged 0-14 years in China. Methods: The studies on the prevalence of asthma in children in China were systematically retrieved from China National Knowledge Infrastructure (CNKI), WanFang Data, China Science and Technology Journal Database (VIP) and PubMed databases. The search time was up to June 2019, and the study site was located in the asthma surveillance cities. Random effect model was used to calculate the combined prevalence of asthma and its 95% confidence interval ( CI ). The subgroup analysis was conducted by period, sex and region. All analyses were performed by using Stata 15.1 and R Studio software. Results: Among 2 624 articles, 67 met the eligibility criteria, and the survey time was from 1989 to 2015. A total of 1 661 076 children were involved and 40 737 asthma cases were confirmed from 26 provinces, municipalities and autonomous regions. The prevalence of asthma varied greatly among different studies, ranging from 0.5% to 9.82%. Meta-analysis showed that the combined prevalence of asthma in Chinese children aged 0-14 was 2.6% (95% CI : 2.1%-3.1%), about 3.2% (95% CI : 2.6%-3.8%) for boys and 1.9% (95% CI : 1.6%-2.3%) for girls. The subgroup analysis showed a significant variation of the prevalence over different years, genders and regions ( P <0.05). The prevalence of asthma in boys was consistently higher than that of girls. The overall prevalence of asthma showed an upward trend. Before 2010, the prevalence of asthma in the eastern region was higher than that in the central and western regions. The prevalence of asthma across regions showed a significant change and the prevalence of asthma in the central region was significantly higher than that in the eastern and western regions from 2010 to 2015 ( P <0.05). Conclusion: The asthma prevalence of children aged 0-14 in China is generally increasing, and the prevalence rate of boys is higher than that of girls. The prevalence rate in the central region is significantly higher than that in the eastern region from 2010 to 2015, suggesting that those regions should strengthen the early prevention and intervention of asthma and implement a sex-specific information dissemination strategy.

Objective: The study intends to identify gap in HIV/AIDS awareness dissemination between the official channel delivery and the needs of adolescents. Methods: We crawled all the HIV/AIDS queries from "Baidu zhidao" till June 11st, 2018. "Baidu zhidao" inquiry and information form official public service announcement (abbreviated for "official delivery" hereafter) were the data source for comparative analysis. We categorized the text data into four kinds, "prevention", "testing and treatment", "symptoms and infection" and "legalization and policies" according to official categorization. Word segmentation was used for text mining and word frequency statistics, as well word cloud was used for word frequency visualization (all based on a comparison after removing the useless words). Results: Of the official delivery, the proportion of prevention category accounted for 32.3% ( n= 162) (ranks 1 st ), and the proportion of legalization and policies category was 14.1% ( n= 71). While among the "Baidu zhidao" inquiry information, the proportion of testing and treatment category accounted for 51.7% ( n= 51 264), and the proportion of prevention category accounted for 11.4% ( n= 11 272). The frequencies of same terms/ repeated terms of two channels accounted for 60% (59.3%-63.9%) of each category among the official delivery, of which, the proportion of interest terms comparatively less and more diverse in "Baidu zhidao" inquiries. The proportion of the terms frequency of each category was about 45% in "prevention, testing and treatment", 34.3% ( n= 14 781) in "symptoms and infection" and 17.0% ( n= 5 744) in "legalization and policies", respectively. Conclusion: A big gap was identified between the available official source and inquiries' term, especially word frequency discrepancy between "legalization and policies" and "prevention" categories. It underscore the necessity for the official channel to address the needs and interests of adolescents in the future.

We sought to identify the differences between adolescents left behind in their home villages/towns (LBA) and non-left behind adolescents (NLB) on subjective well-being and family functioning due to parental migration in south China. We used a stratified cluster sampling method to recruit middle school students in a city experiencing population-emigration in Jiangxi Province in 2010. Participants included adolescents from families with: (1) one migrant parent, (2) both parents who migrated, or (3) non-left behind adolescents (i.e., no migrant parent). To determine predictors of subjective well-being, we used structural equation models. Adolescents left behind by both parents (LBB) were less likely to express life satisfaction (P = 0.038) in terms of their environments (P = 0.011) compared with NLB. A parent or parents who migrated predicts lower subjective well-being of adolescents (P = 0.051) and also lower academic performance. Being apart from their parents may affect family functioning negatively from an adolescent's viewpoint. Given the hundreds of millions of persons in China, many who are parents, migrating for work, there may be mental health challenges in some of the adolescents left behind., (Copyright © 2018 The Editorial Board of Biomedical and Environmental Sciences.

This paper has introduced the terms, concept and characteristics of superfine comminution of traditional Chinese medicine. The progress in the study on the superfine comminution of the single drug and compound prescription was analyzed, and work principles of equipment in common use for superfine comminution were outlined. The future application of superfine comminution technique in traditional Chinese medicine was forecast and the problems that should be solved during the future research work were also pointed out in the paper.
