RESUMO

<p><b>OBJECTIVE</b>To explore the effect of Chinese drugs for Pi strengthening Shen benefiting (CDPSSB) on the immunity function of HIV/AIDS patients' specific T cells.</p><p><b>METHODS</b>Totally 20 patients were randomly recruited from the treated group [treated by CDPSSB combined highly active anti-retroviral therapy (HAART)] and 23 patients were randomly recruited from the control group (treated by HAART alone). All patients were follow-up infected persons form You'an Hospital between from June 2010 to June 2012. CD4+ T absolute counts and HIV viral load were detected. Meanwhile, HIV whole gene overlapping peptides were used as stimulating antigen. The response intensity of HIV specific T cells was detected in the two groups.</p><p><b>RESULTS</b>There was no statistical difference in CD4 T absolute counts or HIV viral load between the two groups (P > 0.05). The response intensity of HIV specific T cells was significantly enhanced in the treated group, when compared with the control group (P < 0.05). Along with elongation of treatment time (6, 12, 18, and 24 months) in the treated group, the response intensity of HIV specific T cells showed enhancing tendency, but there was no statistical difference among these time points (P > 0.05).</p><p><b>CONCLUSION</b>CDPSSB could enhance improve the immunity function of HIV specific T cells, which might be one of its mechanisms.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the pathogenesis of ischemic-type biliary lesions (ITBLs) in post-liver transplant patients and the possible therapeutic mechanisms of sirolimus.</p><p><b>METHODS</b>The clinic data of 32 post-liver transplant patients with ITBLs from May 2004 to December 2010 was analyzed. There were including 25 male and 7 female patients with a median age of 46 years (ranging from 19 to 61 years). Patients were divided into those who received sirolimus (sirolimus group) and those who did not (control group). The expression of IL-2, FoxP3, and IL-10 in the portal area, liver function indexes, and bile duct injury score were assessed pre-ITBL, when ITBLs were identified, and after 6 months of sirolimus treatment.</p><p><b>RESULTS</b>Compared with pre-ITBL optical density (OD) values, there was a significantly increase in IL-2 OD(0.138 ± 0.050 in control group and 0.141 ± 0.052 in sirolimus group), but not FoxP3 and IL-10 OD in both groups at the time ITBLs were diagnosed. After 6 months of treatment, the IL-2, FoxP3, and IL-10 OD values in the control group were not different from those when ITBLs were diagnosed. There was a significant reduction in post-therapy IL-2 OD(0.107 ± 0.043, t = 2.087, P = 0.044), and a significant elevation in FoxP3(0.213 ± 0.039) and IL-10 OD(0.187 ± 0.048) in sirolimus group as compared with those when ITBLs were diagnosed(t = -3.822 and -4.350, both P < 0.01). There was a significant increase in serum levels of ALT, AST, total bilirubin, γ-glutamyl transpeptidase and ALP at the time ITBLs were diagnosed compared with pre-ITBL levels in both groups. After 6 months of treatment, the above indexes had not changed in the control group, but significantly improved in the sirolimus group, and the bile duct injury score in the sirolimus group had significantly decreased(4.4 ± 2.4, Z = -2.568, P = 0.010). The 1-year and 3-year graft survival rates in the control group were 6/13 and 5/13, respectively, and 17/19 and 13/19, respectively, in the sirolimus group (χ(2) = 7.166, P = 0.007; χ(2) = 5.398, P = 0.020, respectively).</p><p><b>CONCLUSIONS</b>Sirolimus can downregulate IL-2 expression and upregulate FoxP3 and IL-10 expression, thereby stimulating FoxP3+ Treg cells, suppressing immunopathological damage, and promoting epithelial repair in bile ducts.</p>
