Objective To investigate the expression of NF-?B and its significance to sciatic nerve in diabetic rats.Methods The model of diabetes was induced by streptozotocin.The sciatic nerve conduction velocity(NCV)and NF-?B activity were observed at 1 month(DM1),3 months(DM3)and 6 months(DM6)during the experiment respectively.Results Compared with normal control group,NCV was significantly slower in DM3 and DM6 groups.There was no difference in NCV between normal control group and DM1 group.The expression of NF-?B,by electrophoretic mobility shift assay(EMSA),was markedly higher in DM groups(P

Objective To investigate the correlation between umbilical cord blood tire mass measles antibody and maternal measles antibody degrees,in order to evaluate the crowd measles antibody level and provide scientific basis for lasting elimination of measles.Methods Collected 40 cases of healthy maternal venous blood and their paired cord blood,enzyme-linked immunosorbent assay (ELISA) was used for the detection of measles antibody.Results In the 1:200 level,mother blood and umbilical cord blood of measles antibody level were 11.29 ±4.81 and 12.76 ± 5.32,in the 1:800 level were 6.89 ±4.11 and 8.28 ± 4.91,both had correlation (r =0.575,0.618,P ＜0.05).Conclusions Measles antibody titers of maternal venous blood and paired cord blood are highly correlated.The results show that maternal measles antibodies could pass through the placenta to the daughter,and measles antibody titers detected in umbilical cord blood can be used not only to assess the maternal measles antibodies level,but also can be used as a predictor of measles antibody levels for newborns and young children.
