[Estimation on the HIV-1 incidence among high risk groups using the pooling RNA technique].

Objective: To timely identify the HIV-1 infection in window-period and to estimate the HIV-1 incidence among people who came for voluntary counseling and testing (VCT) service as well as men who have sex with men (MSM), respectively.

Methods: HIV antibody negative samples that were determined by screening tests between January and October 2012, were collected and tested with pooling HIV-1 RNA testing technique (2-staged pooling by 50:1, 10:1). Positive cases were followed-up for HIV antibody testing while HIV incidence was calculated under Ron Brookmeyer' s method, among VCT and MSM populations.

Factors influencing HIV infection in men who have sex with men in China.

To identify risk factors for HIV infection among men who have sex with men (MSM) and to provide a theoretical basis for prevention interventions. Between December 2011 and August 2012, a case-control study was conducted among MSM who underwent voluntary counselling and testing for HIV. Confirmed HIV-positive MSM were included in the case group, and HIV-negative MSM were included in the control group.

[Association of diabetes and early failure of arteriovenous fistula in the end stage of renal diseases].

Objective: To determine the association of diabetes and glycemic control with early failure of native arteriovenous fistula(AVF).

Methods: 266 patients with end stage renal diseases(ESRD) were recruited and divided into non-diabetic group (165), HbA1C < 7% group (51) and HbA1C > or = 7% group (50). Clinical indicators and early failure of AVF were examined.
