1.Research progress of pigment epithelium-derived factor ,insulin resistance and type 2 diabetes
Chinese Journal of Diabetes 2017;25(3):277-280
Pigment epithelium-derived factor (PEDF ) was originally found fromretinal pigment epithelium. It is confirmed that it plays an anti-angiogenic and apoptosis role in diabetic microangiopathy. Recently ,PEDF has been found to have a close relationship with insulin resistance ,type 2 diabetes and diabetic macroangiopathy. But the mechanism is unclear. More and more researches focused on its role in oxidative stress. PEDF may become a new target for diabetes and diabetic complication treatment and also a predictive factor for the disease.

Objective: To observe the effects of erigeron injection on the biochemical indicators of hepatotoxicity caused by ischemia and reperfusion of the mice intestine. Methods:A experimental model of liver lesion induced by ischemia-reperfusion of the mice intestine was set up. Serum was obtained after 20 minutes of ischemia followed by 1 hour of reperfusion. Contents of SOD and MDA in liver were measured. Results: The serum ALT significantly increased following ischemia and reperfusion, which was attenuated by the erigeron injection (P<0.01). Erigeron injection can also increase the contents of SOD and MDA in the mice liver (p<0.05 and 0.01, respectively). Conclusion: Erigeron injection can improve the biochemical indicators of liver lesion induced by ischemia and reperfusion of the mice intestine. It is indicated that the protective effects of erigeron injection was related to anti-oxidation mechanisms.

Abstract Objective: To study the relationshiop between the HBV pre-c mutant and the clinical the, the host immunity. Methods: Mu-tation specific PCR(msPCR) was employed for detecting pre-c mutant in 92 cases with HBV-DNA positive;T subpopulations were determinedby APAAP immune-bridge assay; the cytokines (TNF?、 sIL-2R ) levels by ELISA. Results: 57 cases had Pre-c mutant, the rate was ahaut 62 %;pre-c mutant existed popularly in different e systems status, mainly in anti-HBe(+) serum. The reat increased with the deterioration of liverfunction, and was highest in fulminant hepatitis, the percentage of CD4 T lymphocyte and the ratio of CD4/CD8 were aignificantly lower in mu-tational group than in wild group,but CD8 T lymphocyte was obviously higher, the quantity of sera TNF? and sIL-2R in mutational group wereobviously higher than in wild group, both groups were obviously higher than control group. Conclusion:PreC 1896 mutant existed popularly inpatients with HBV infection. There were more serious disturbance in host immunity in mutant group. The mutant may be associated with the pre-ssare of host immune system.The mutant type virus could provoke host immunity resulting in severe liver damage.
