ObjectiveTo investigate the effect of cardiopulmonary bypass (CPB) on the secretory function of islet cells in rabbits.MethodsTwenty adult New Zealand white rabbits of both sexes,weighing 2.5-3.0kg,were randomly divided into 2 groups ( n =10 each):sham operation group (group S) and CPB group.The rabbits were anesthetized with 3％ pentobarbital sodium 30 mg/kg.Blood samples were collected from the left femoral artery at 5 min after anesthesia (T1),immediately before CPB (T2 ),immediately after aortic clamping (T3 ),and at 5,35 and 75 min after aortic unclamping (T4-6) in the two groups for determination of levels of blood glucose,insulin and glucagons.Insulin resistance index was calculated.ResultsCompared with group S,the blood glucose concentration and levels of insulin and glucagons and insulin resistance index at T3-6 were significantly increased in group CPB ( P ＜ 0.05).ConclusionAlthough increase in blood glucose enhances the secretion of insulin in islet β cells,hyperglycemia cannot be compensated completely by the increased insulin during CPB in rabbits.The increase in blood glucose may be related to islet α cell resistance.

Objective To investigate the expression of miR-200c in endometrial carcinoma and its correlation with ZEB2 protein. Methods The expression levels of miR-200c and ZEB2 gene and protein in tissues were detected. The expression of miR-200c in endometrial carcinoma RL95-2 cell line was inhibited by using antisense oligonucleotides and its effect on cell invasiveness was tested. The expressions of ZEB2 gene and protein in cells were detected. Results The expression levels of miR-200c and ZEB2 mRNA and protein in endometrial tissues were significantly higher than those in adjacent tissues and control group (P < 0.05). The average penetrating number in antisense miR-200c transfected group was significantly less than negative control group and liposome group (P < 0.05). The expression levels of ZEB2 gene and protein in antisense miR-200c transfected group were lower than the negative control group and liposome group (P < 0.05). Conclusion The expression of mRNA-200c in endometrial carcinoma was high and it might be promoting tumor cell invasion and metastasis by regulating ZEB2.
