AIM: To investigate the effects of globular adiponectin (gAd) on the expression of adiponectin receptor 1 (AdipoR1) in human umbilical vein endothelial cells (HUVECs), and on the apoptosis induced by advanced glycation end products (AGEs). METHODS: HUVECs were treated with the indicated concentrations of AGEs for 24 h or 48 h in vitro. The cells in gAd treatment group were pretreated with gAd for 24 h, and then were treated with AGEs for another 24 h or 48 h. Cell variability was quantified by MTT assay. Apoptotic cells were detected by flow cytometry with Annexin-FITC/PI double staining. AdipoR1 mRNA in the cells was determined by quantitative real time reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS: The viability of HUVECs treated with AGEs decreased significantly as compared to the cells treated with HSA (control, P<0.05). Under the same condition of AGEs exposure, the viability of the cells treated with gAd was greatly higher than that of the cells without gAd treatment (P<0.01). The apoptotic rate of HUVECs was significantly elevated by AGEs treatment vs HSA treatment observed by Annexin V-FITC/PI double staining analysis with flow cytometry (P<0.05). Under the condition of AGEs stimulation, the apoptosis of HUVECs was decreased by pretreatment with gAd as compared to that of the cells without gAd treatment (P<0.01). Measured by quantitative real time PCR, AGEs decreased the expression level of AdipoR1 mRNA and gAd increased the expression of AdipoR1 mRNA contrarily (P<0.05). CONCLUSION: AGEs increase the apoptotic rate of HUVECs in a concentration dependent manner and gAd promotes the AdipoR1 mRNA expression.

Objective To investigate IL-17 as adjuvant effect on the humoral and cellular immune responses to HIV DNA vaccine by immunizing mice with HIV DNA vaccine plus IL-17. Methods We immunized the BALB/c mice with pGX-Env alone, or with pcDNA3-IL-17 by intramuscular injection. The immunization was performed on week 0, 2. The concentration of the anti-Env IgG, the stimulated index of T lymphocyte proliferation, and the expression of IFN-γ, IL-4 and IL-17 in CD4~+T cell and IFN-γ in CD8~+ T cell, specific in vivo cytotoxic T lymphocyte (CTL) activity were detected at week 4. Results We show here that IL-17 as a molecular adjuvant with the HIV DNA vaccine, pGX-Env, can enhance immune responses. Interestingly, IL-17 has no adjuvant effect on the responses for T cell proliferation, antibody production and expressions of IFN-γ, IL-4 and IL-17 in CD4~+ T cells, but rather on the up-regulation of IFN-γ in CD8~+ T cells and CTL in vivo significantly(P<0.05). Conclusion The data suggest that IL-17 as the molecular adjuvant may not effect the development and differentiation of CD4~+ Th cells, but directly affect on the CD8~+ T cell functions. The novel functionality of IL-17 on adaptive immunity may lead to develop effecfive HIV DNA vaccination targeted to potentiate the CD8~+ T cell functions.

OBJECTIVETo observe the effect of Chinese medicine and pharmacy (CMP) on the mortality of senile HIV/AIDS patients as adjunctive therapy.
METHODSHIV/AIDS patients of a certain rural area of Hanna Province, who were recruited in national CMP HIV treatment trial program (NTCMTP) in 2004, were enrolled as the CMP treatment group. HIV/AIDS patients in the same village without recruiting in NTCMTP were enrolled as the non-CMP treatment group. Data related to subjects were collected from the database of NTCMTP and National HAART Reporting System. Multiple regression analysis under Cox proportional hazard model was applied to examine the risk factors for death of senile HIV/AIDS patients.
RESULTSA total of 436 HIV/AIDS were enrolled in this study, 204 in the CMP treatment group and 232 in the non-CMP treatment group. There were 70 AIDS-relative deaths in the CMP treatment group, with 8-year mortality rate of 37.74%. There were 111 AIDS-relative deaths in the non-CMP treatment group, with 8-year mortality rate of 48.34%. The 8-year mortality rate was higher in the non-CMP treatment group than in the CMP treatment group (chi2 = 5.136, P < 0.05). Results of univariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.41 times that of the CMP treatment group (P < 0.05). Result of multivariate Cox proportional hazards regression analysis showed the hazard ratio in the non-CMP treatment group was 1.44 times that of the CMP treatment group (P < 0.05). Besides, gender and marital conditions were significantly associated with death of HIV/AIDS patients.
CONCLUSIONCMP treatment was favorable to lower the mortality rate of senile HIV/AIDS patients, and its objective evaluation awaits for further prospective study.

In the present study, packaging system composed of pAAV-CMV-GFP, pAAV-RC and pHelper were transfected into human embryonic kidney 293 cells (HEK293 cells) mediated by polyethyleneimine (PEI) to explore an optimal transfection condition. Different total plasmid DNA dosages (1, 2, 3, 4, 5, 6 μg) and different PEI/Plasmid ratios (1:1, 3:1, 5:1, 7:1) were tested with detection of green fluorescence protein (GFP) with ImagePro Plus6. 0 Software. Then transfection efficiency of the optimized transfection system was further observed for different time periods(12, 24, 36, 48, 60, 72 h). The results showed that total plasmid dosage of 4 μg/well with PEI/plasmid ratio of 3 : 1-5 : 1 was an efficient transfection condition. Transfection efficiency-time curve was an S-shaped curve. Transfection efficiency reached a plateau at 60 h after transfection. The optimized conditions for PEI-mediated transfection at the optimal time result in enhanced transfection efficiency of triple plasmid into HEK293 cells.

For most variety of vaccines, two types of effects-direct and indirect, can result from immunization programs. Unimmunized individuals in the population that receive immunization program can benefit from the vaccines in addition to the protection from immunization.The classical vaccine trails allocate individuals into study and control arms with individual randomization, so the programs' cost-benefit is underestimated due to the impossible measurement on indirect effect. The objectives of the present work are to introduce the conceptual framework,developed by Halloran et al, for four types of study designs that differentiate and account for direct,indirect, total and overall effects of intervention programs, and to explain the relationships of these effects as well. With the examples of field trails of oral cholera vaccines in Bangladesh and Vi typhoid vaccine in India, further issues refer to the identification of indirect effect. The application in practice is also discussed.
