BACKGROUND: A large number of researches have confirmed that hypertension, vascular nephrosclerosis and chronic systemic inflammatorome were the importance factors of chronic allograft dysfunction. Hyperuricemia is associated with primary hypertension and vascular nephrosclerosis, and can result in chronic systemic inflammatorome, but it was uncertain whether post-transplantation hyperuricemia and its lesion influence the long term graft function. OBJECTIVE: To investigate the prevalence of hyperuricemia in renal transplant recipients (RTRs) before and after transplantation and the influence of hyperuricemia on long term graft function. METHODS: A total of 216 renal transplant recipients [146 males with the mean age of (40.98±11.09) years and 70 females with mean age of (40.01±11.62) years]with normal renal function after transplantation were selected from PLA Center of Kidney Transplantation and Dialysis, the 181 Hospital of Chinese PLA. In order to compare the influence of different hyperuricemia status on the long term graft function, the patients were divided into 4 groups according their pre-transplant baseline and post-transplant serum uric acid (SUA) levels, SUA normal group, pre-transplant high SUA group, post-transplant high SUA group and both pre-transplant and post-transplant high SUA group. The patients were also divided into 3 groups according to their post-transplantation SUA level to study the influence of SUA on the long term graft function, normal SUA group, hyperuricemia (SUA < 500 μmol/L) group and hyperuricemia (SUA > 500 μmol/L) group. Effects of hyperuricemia and SUA levels pre-and post-transplantation on long term graft function were observed. RESULTS AND CONCLUSION: Hyperuricemia existed in 34.2% male RTRs and 37.7% females before transplantation, while it existed in 36.2% male RTRs and 42.4% females at the first month post-transplantation when they had normal Scr levels. The incidence rate of post-transplant hyperuricemia in female RTRs was significantly higher than male RTRs (P < 0.05). The average post-transplantation SUA levels in both male and female RTRs were significantly higher than those before transplantation (P < 0.01). At follow-up end, the pre-transplantation SUA levels did not significantly influence on the long term graft function (P > 0.05), meanwhile the RTRs with continuous post-transplant hyperuricimia had poorer long term graft function than those with normal post-transplantation SUA levels. It is indicated that hyperuricemia is more common in post-transplantation recipients, especially in female RTRs, when compared to pre-transplantation, and post-transplantation hyperuricemia often existed in renal transplant recipients with normal graft function. Furthermore it is suggested that post-transplantation hyperuricimia, but not pre-transpiantation hyperuricemia, could also act as a factor inducing chronic renal allograft dysfunction.

Objective: To investigate the influence of TGF-β and IFN-γ on the proliferation, migration and invasion of melanoma cells. Methods: Melanoma cells were cultured in vitro. When tumor cells were confluent about 80% degree, cytokines were added into cell culture media. The concentration of TGF-β and IFN-β was 5ng/mL and 10ng/mL, respectively. Melanoma cells were divided into free-cytokine group, TGF-β group,IFN-γ group, TGF-β and IFN-γ group. Tumor cells in each group were then incubated for 8h, 16h, 24h, 32h,40h and 48h, respectively. After incubation, fixing and staining with SRB, the optical densities and percentage viability were then determined by absorption at 540 nm (A 540). The scarification of tumor cells in each group on the surface was created by a 2001μL pipette tube. The motility of tumor cells in each group was assessed by measuring the distance between scarifications. The speed of the scuffing closure was monitored after 12h.The invasive ability of melanoma cells was observed by transwell cultivation. The tumor cells that invaded through the Matrigel and adhered to the bottom of the outside membrane were determined by absorption at 595 nm (A595). Gelatin zymography assay was used to examine the levels of matrix metalloproteinases-2 (MMP-2) and matrix metalloproteinases-9 (MMP-9) activity when the tumor cells were treated with cytokines after 24h. MMP-2 and MMP-9 activity was demonstrated by gradation in the sodium dodecyl sulfate polyacryl-amide gel electrophoresis (SDS-PAGE) gelatin. MMP-2 and MMP-9 activity was determined by Image analy-sis Software. Results: TGF-β promoted the proliferation, migration and invasion of melanoma cells (P<0.05).However, IFN-γ inhibited the proliferation, migration and invasion of melanoma cells (P<0.05). The effect weakened or disappeared when both of them were used (P>0.05). Conclusion: In vitro, TGF-β may affect the inhibitory effect of IFN-γ on the proliferation, migration and invasion of melanoma cells. This study provided a better understanding of the relationship between tumor and inflammatory factors and established a good ba-sis for future research.

Objective To compare clinical outcome of microvascular decompression (MVD) and percutaneous balloon compression (PBC) by using a prospective cohort study in order to provide a reliable evidence for the clinical decision-making. Methods Patients with trigeminal neuralgia hospitalized at Hangzhou First People′s Hospital in 2010 were chosen as database for cohort study. The patients were divided into MVD group (30 cases) and PBC group (30 cases). The clinical efficacy was followed by independent observers for 36 months after surgery. Chi-square test for hierarchical data, t test for quantitative data, and Kaplan-Meier plot for clinical outcomes were applied in the research. The endpoint was follow-up accomplishment or severe occurrence. Results Sixty patients were included in the research till the endpoint. The general records before surgery were almost the same with the literature records. By comparing painless period, mild and severe relapse, MVD group was superior to PBC group (P < 0.05). As for the painless survival period, MVD group was 96.7% of pain free after 1 year, 93.3% after 3 years, while PBC group was 90.0% after 1 year and 83.3% after 3 years. Regarding 3 years of follow-up, the relapse seemed occurred after 1 year in both groups. Conclusions As a curative and nondestructive procedure , MVD is more effective and has longer lasting pain free period , which should be considered as the first choice of treatment for trigeminal neuralgia in healthy people.
