HIV/AIDS epidemiology and prevention in China / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To review HIV/AIDS epidemic history, current situation and prevention policy in China. Data sources Information included in this article was identified by searching PUBMED (1997 - 2006) online resources using the key terms "HIV/AIDS", "epidemic", "prevention", and "China". Study selection Original milestone articles and critical reviews written by major pioneer investigators of the field were selected.</p><p><b>RESULTS</b>The key issues related to the HIV/AIDS epidemic situation in China and Chinese government prevention policy were summarized. HIV/AIDS epidemic groups and trends for HIV transmission were discussed.</p><p><b>CONCLUSION</b>In January 2006, 650 000 people were estimated to be living with HIV in China. The overall HIV/AIDS epidemic is at a low level (0.05%) and concentrated in several at risk populations. However, the data show that new cases of HIV infection are growing every year and spreading from at risk populations to the general population. Premier WEN Jia-bao announced the "Four frees and one care" policy and the Chinese government has developed a series of programs with strong policy measures to stop the spread of HIV/AIDS in China.</p>

The correlation of HBeAg expression and HBV-DNA in serum or peripheral blood mononuclear cells in patients with chronic hepatitis B / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To study the relationship between HBeAg expression and HBV-DNA in serum and peripheral blood mononuclear cells (PBMCs).</p><p><b>METHODS</b>208 patients with chronic hepatitis B were included in this present study. HBV-DNA in the PBMCs were performed by polymerase chain reaction (PCR), with the serum HBV-DNA level being determined by the way of fluoresces quantities PCR (FQ-PCR). Meanwhile, HBV-GM was also detected via enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>There were 106 patients for positivity in the HBV-DNA level of PBMCs with 102 for negativity, in which the HBV-DNA high levels (HBV DNA load > or = 1.0E5) in serum were 91.5%, 45.1% (chi2=52.12, P>0.01) respectively, with 76.4% and 50.9% (chi2=21.55, P>0.01) for the positive percentage of HBeAg expression.</p><p><b>CONCLUSION</b>A significantly positive correlation was found between HBV-DNA in PBMCs and serum HBV-DNA along with the positive percentage of HBeAg, indicating that obvious PBMCs' increase infected by HBV in patients with positivity of HBeAg and high level of serum HBV-DNA.</p>
