Mortality risk in the population of HIV-positive individuals in Southern China: A cohort study.

To evaluate the mortality risk in the HIV-positive population, we conducted an observational cohort study involving routine data collection of HIV-positive patients who presented at HIV clinics and multiple treatment centers throughout Guangxi province, Southern China in 2011. The patients were screened for tuberculosis (TB) and tested for hepatitis B (HBV) and C (HCV) virus infections yearly. Following the registration, the cohort was followed up for a 60-month period till the end-point (December 31, 2015).

Implementation of a "County-Township-Village" Allied HIV Prevention and Control Intervention in Rural China.

In China, rural areas are a weak link of HIV/AIDS prevention and control. From September 2011, an innovative "county-township-village" allied intervention was implemented in Longzhou County, Guangxi, which assigned the tasks of HIV/AIDS prevention and control to the county Centers for Disease Control and Prevention (CDC), township hospitals, and village clinics, respectively, instead of traditional intervention in which the county CDC undertook the entire work. A 6-year consecutive cross-sectional survey, including 3-year traditional intervention (2009-2011) and 3-year innovative intervention (2012-2014), was conducted to evaluate the effects of the new intervention.

[Influential factors analysis on the survival time of patients infected with tuberculosis and HIV].

Objective: To investigate the predictors that reduced the survival time on HIV positive TB patients during their first year's anti-TB therapy.

Methods: A retrospective study was conducted to review 519 TB/HIV co-infection patients from an Internet based TB surveillance system. We collected information of demography, HIV status, CD4+ lymphocytes count, antiretroviral therapy (ART), sputum smear results of diagnosis and around 2 months' initiation of anti-TB therapy, et al.

[Feature analysis on patients died from co-infection of Mycobacterium tuberculosis and human immunodeficiency virus in Guangxi, from 2007 to 2012].

Objective: To understand the general feature of patients with Mycobacterium tuberculosis (MTB) and human immunodeficiency virus (HIV) co-infectious (TB/HIV) in Guangxi, from 2007 to 2012.

Methods: Information regarding individuals that the contributory causes of death were due to MTB infection among HIV as the underlying cause of death from the Vital Registration System, together with bacterium smear or culture results, onset of TB, time that TB was diagnosed and entered an Internet base TB surveillance system was collected and checked. Data including information on time of death, age, occupation, the underlying cause of death among TB patients, bacterium distribution, average age of death, interval from onset to death, percentage of TB/HIV co-infection patients among all the patients etc, were all analysed.

Impact of supplementary immunization activities in measles-endemic areas: a case study from Guangxi, China.

Because of limited resources, each year during the period from 1999 through 2007, only about one-quarter of the 111 counties in Guangxi province were selected by means of risk assessment to participate in Supplementary Immunization Activities (SIAs), targeting children aged 8 months to 14 years during 1999-2003 and 8 months to 10 years during 2004-2007. Approximately 2 million doses of measles vaccines were administrated each year during SIAs. Estimated from the National Notifiable Diseases Surveillance System, with a reliable internal consistency over years, the average annual incidences of measles before SIAs (1993-1998), during the first phase (1999-2003), and during the second phase (2004-2007) were 16.

[Study on liver damage caused by anti-TB drug intermittent treatment on patients with HBV-TB co-infection].

Objective: To study the features of liver damage caused by anti-TB medicines among patients with TB-HBV co-infection, in order to complement and improve the implementation of DOTs strategy in the region.

Methods: A historical cohort study was conducted including the process of reviewing and analyzing files of the 781 naive TB patients hospitalized from June 2004 to October 2005. Cases were divided into HBsAg (+) group and HBsAg (-) group.

The three networks framework to deal with public health emergencies in Guangxi, China.

Objective: To improve the detection and control of infectious diseases in Guangxi, China.

Setting/participants: Guangxi province in southwest China has almost 50 million people, of whom approximately 30% reside in urban and 70% in rural areas. There are 12 minority nationality groups living in the region.

Motorcycle ownership and injury in China.

Background: China has made tremendous progress in its economic development in the past two decades. Accompanying this economic development has been an evident shift in the modes of transport, from walking and cycling to the use of motorcycles and, increasingly, four-wheel vehicles. Such changes are likely to have also produced changes in the patterns and numbers of road traffic injuries, including increases in motorcycle injuries.
