Methods:The effect of chrysin on HIV1 infection and replication in vitro were detected by cell fusion of MT2 cells and HIV1ⅢB/H9 cells labeled calceinAM and the inhibition study of syncytia formation and p24 production monitored in culture supernatant of MT2 cells infected by HIV1ⅢB, respectively. Flurescence conjugated monoclonal antibodies and flow cytometry were used to detect the expression of CD69 by activated CD4+T in response to PHA.

When 3 mmol·L-1 crocin treated T24 cells for 48h, the difference was significant compared with the control group ( P .05). Crocin induced wide changes of the gene expression profile of T24 cells. A total of 836 genes were up-regulated or down-regulated by more than 2 times, which were involved cell cycle controlling, DNA cell apoptosis, replication factor, and so on.

Although, in our study the functional characteristics of these T cells was not investigated, we can speculate that in HBsAg inactive carriers, a dynamic population of HBV specific T cells, both in the liver and periphery exists, that is able to produce antiviral cytokines (i.e. IFN-gama) and thus suppress HBV replication without cytolytic liver damage.

Thermoanaerobacter tengcongensis is a rod-shaped, Gram-negative, anaerobic eubacterium that was isolated from a fresh water hot spring in Tengchong, China. Using a"whole-genome-shotgun"method, we sequenced its 2, 689, 445-bp genome from an isolate, MB4〓(Genbank Accession Number AE008691). The genome encodes 2, 588 predicted coding sequences . Among them, 1, 764 (68. 2％) are classified according to homology to other documented proteins, and the rest, 824 CDS (31. 8％), are functionally unknown. One of the interesting features of the T. tengcongensis genome is that 86. 7％ of its genes are encoded on the leading strand of DNA replication.

Viral replication and microbial translocation from the gut to the blood during HIV infection lead to hyperimmune activation, which contributes to the decline in CD4+ T cell numbers during HIV infection. Programmed death-1 (PD-1) and interleukin-10 (IL-10) are both upregulated during HIV infection.
