Methods The samples from outpatients,inpatients with surgical treatment and the quality control samples from center for disease control and prevention were detected for HIV p24 antigen and anti-HIV antibody by VIDAS HIV DUO Ultra and then compared with the third-generation enzyme-linked immunosorbent assay(ELISA) and particle agglutination(PA).

Based on the fact that an AP-injective ring satisfies the C_2 condition, conditions for an AP-injective ring to satisfy C_1 condition were found, then its continuity was deduced by combining with Baer ring, duo ring, semiperfect ring, MI-ring and so on.

Detection of env Gene Sequence of HIV-1 Screened from Long-term Infectors;

Several research groups have recently reported that persistent GB virus C(GBV-C) co-infected with human immunodeficiency virus(HIV) leads to slower AIDSs disease progression than HIV-1 infection alone.

OBJECTIVE To rationally design new inhibitors targeting to HIV-1 transmembrane protein-gp41 METHODS Two Molecular Docking methods were adopted to explore the binding mode between gp41 and its inhibitor NB-2;a de novo drug design method(LeapFrog)was used to optimize the structure of NB-2 in order to design novel,potent,and selective inhibitors of gp41.
