National age-specific mortality trends for cervical and breast cancers in urban-rural areas of China from 2009 to 2021: a population-based analysis.

Background: Cervical and breast cancers are among the top 4 leading causes of cancer-related mortality in women. This study aimed to examine age-specific temporal trends in mortality for cervical and breast cancers in urban and rural areas of China from 2009 to 2021.

Methods: Age-specific mortality data for cervical and breast cancers among Chinese women aged 20-84 years were obtained from China's National Disease Surveillance Points system spanning the years 2009 to 2021.

Constructing artificial gap junctions to mediate intercellular signal and mass transport.

Natural gap junctions are a type of channel protein responsible for intercellular signalling and mass communication. However, the scope of applications for these proteins is limited as they cannot be prepared at a large scale and are unable to spontaneously insert into cell membranes in vitro. The construction of artificial gap junctions may provide an alternative strategy for preparing analogues of the natural proteins and bottom-up building blocks necessary for the synthesis of artificial cells.

Innate and adaptive immune escape mechanisms of hepatitis B virus.

Chronic hepatitis B virus (HBV) infection is an international health problem with extremely high mortality and morbidity rates. Although current clinical chronic hepatitis B (CHB) treatment strategies can partly inhibit and eliminate HBV, viral breakthrough may result due to non-adherence to treatment, the emergence of viral resistance, and a long treatment cycle. Persistent CHB infection arises as a consequence of complex interactions between the virus and the host innate and adaptive immune systems.

[Meta-analysis of asthma prevalence of children aged 0-14 in surveillance cities of China].

To understand the prevalence of asthma and its variation over time in children aged 0-14 years in China. 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.

[Using text mining to identify gap in acquired immunodeficiency syndrome related information dissemination between the official channel delivery and the needs of adolescents].

The study intends to identify gap in HIV/AIDS awareness dissemination between the official channel delivery and the needs of adolescents. 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.

Effects of Antiretroviral Therapy and HIV Exposure in Utero on Adverse Pregnancy and Infant Outcomes: A Prospective Cohort Study in Guangzhou, China.

Objective: This study aimed to evaluate the effects of in-utero exposure to HIV and ART on pregnancy outcome and early growth of children.

Methods: 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.

A social interaction field model accurately identifies static and dynamic social groupings.

Identifying whether people are part of a group is essential for humans to understand social interactions in social activities. Previous studies have focused mainly on the perceptual grouping of low-level visual features. However, very little attention has been paid to grouping in social scenes.

Beyond Fitts's Law: A Three-Phase Model Predicts Movement Time to Position an Object in an Immersive 3D Virtual Environment.

Objective: The study examines the factors determining the movement time (MT) of positioning an object in an immersive 3D virtual environment.

Background: Positioning an object into a prescribed area is a fundamental operation in a 3D space. Although Fitts's law models the pointing task very well, it does not apply to a positioning task in an immersive 3D virtual environment since it does not consider the effect of object size in the positioning task.

Innovative analysis of predictors for overall survival from systemic non-Hodgkin T cell lymphoma using quantile regression analysis.

Background: Non-Hodgkin T/NK cell lymphoma is a rare and widely variable type of lymphoma with the most dismal prognosis. This study aimed to investigate varied impact of the clinical indicators to the overall survival (OS).

Methods: We conducted a retrospective study to identify the non-invasive clinical features of T cell lymphoma that can predict prognosis with an innovative analysis method using quantile regression.

Subjective Well-being and Family Functioning among Adolescents Left Behind by Migrating Parents in Jiangxi Province, China.

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.

Available Evidence of Association between Zika Virus and Microcephaly.

Objective: To clarify the possible association between the Zika virus (ZIKV) and microcephaly and understand where we are in terms of research and the debate on the causation between mild maternal clinical features and severe fetal microcephaly.

Data Sources: We did a comprehensive literature review with the keywords "zika" and/or "microcephaly" from inception to May 27, 2016, with PubMed.

Study Selection: Studies were included and analyzed if they met all of the following criteria: "probable or confirmed infant microcephaly" and "probable or confirmed ZIKV infection among mothers or infants".

[Study on the superfine comminution of traditional Chinese medicine].

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.
