[Comparison of three HIV antibody confirmatory assay kits in confirming early HIV infection].

Objective: This study was to compare the performance of three HIV antibody confirmatory assay kits in confirming early HIV infection.

Methods: Five HIV antibody-positive plasma specimens were ten-fold serially diluted and then detected by ELISA. The above diluted specimens were detected with the following three HIV antibody confirmatory assay kits to analyze their sensitivity, including Wantai-RIBA (Recombinant immunoblot assay, Beijing Wantai Biological Pharmacy, China), MP-WB (HIV Blot 2.

[Evaluation of BED-CEIA assay with dried blood spot specimens in China].

Unlabelled: OBJECTIVE; To study the feasibility of using dried blood spot (DBS) specimens in BED-CEIA assay and to estimate the HIV-1 incidence with DBS in China.

Methods: 10 313 participants from 27 voluntary counseling and testing (VCT) sites were enrolled in this study. Both plasma and DBS specimens were collected.

[The preparation and characterization of sol-gel derived zinc modified carbonated hydroxyapatite].

Objective: To prepare zinc-modified carbonated hydroxyapatite (Zn-CHA) coating material via sol-gel method and explore the influence of zinc substitution on physical and chemical properties of biomaterial samples.

Methods: Two kinds of samples with different zinc content and Ca/P molar ratio were prepared. One was fabricated with 4% zinc and the Ca/P molar ratio was 1.

[The experimental study on biodegradable gel membrane applied to prevention of postoperative adhesion of abdominal cavity surgery].

Objective: To develop a new type of anti-adhesion gel membrane and explore its applying technique.

Methods: 24 adult New Zealand white rabbits were used for the experiment research project, the animals were divided into two groups: the experiment group (18 adult New Zealand white rabbits) and the control group (6 adult New Zealand white rabbits). The animal models were established via the abdominal cavity.
