Objective To investigate the role of cell apoptosis in the gut mucosal barrier dysfunction in rats undergoing cardiopulmonary bypass(CPB) . Methods The rat model of CPB was set up. The rats were divided into CPB group, sham operation(SO) group and normal control group. The morphological changes of ileum mucosal tissues were observed by microscope and electron microscope at 3h, 6h, 12h and 24h after operation, respectively. The apoptotic index of gut mucosal epithelial cells was measured with TUNEL method. Results Gut mucosal morphology was normal in CPB group at 3h, 6h and 12h after operation, but gut mucosal epithelial desquamation occurred at 24h after operation. Typical apoptotic cells could be seen with electron microscope in CPB group at every time point. Apoptotic index of gut mucosal epithelial cells significantly increased in CPB group at every time point compared with SO group, and peaked at 6h after operation. Apoptotic cells were mostly located in the gut crypt. Conclusion The data suggested that the apoptosis of intestinal epithelial cells significantly increased at early stage of post-CPB in rats, which might contribute to gut mucosal barrier dysfunction.

Objective: To explore the influence factors of the degenerate oligonucleotide primered PCR(DOP-PCR). Methods: Genome DNA template from the mouse single oocyte or liver tissue were used to perform DOP-PCR. DOP-PCR was carried out with templates of different origin, different gradient dilution, with or without low melting point gel purified to wipe off the small fragment that might interfere with the following analysis, and then PCR of gene FTCD and CBS were carried out to evaluate the influence of these factors on the amplification efficiency and specificity. Results: Compared with genome DNA template from mouse liver, the template from single oocyte had the same efficiency and specificity but a minor yield and different gradient dilution of DNA template had no effect on the efficiency and specificity. Furthermore, there was a higher specificity in the low melting point gel-purified DOP-PCR product than in untreated ones. Conclusion: We have got a satisfactory result and increased specificity from DOP-PCR product purified with the low melting point gel. Single oocyte of mice could be used for further investigation of special genes detection by DOP-PCR and of an optimization in the yield of the products.

Objective To explore the protective effects of pretreatment with alanyl-glutamine dipeptide on intestinal barrier function in rats after cardiopulmonary bypass.Methods CPB model in rats was established.60 SD rats were randomly divided into group G(pretreatment with alanyl-glutamine before CPB for 3 days and primed with it during CPB,n =20),group CPB(n =20) and sham-operation(SH) group(n =20).The diamine oxidase(DAO) activity of plasma and tissue homogenate of intestinal mucosa were measured by spectrophotometry,and the concentration of plasma D-lactate was also detected by spectrophotometry.The levels of plasma lipopolysaccharide(LPS) was measured by tachypleus amebocyte lysate development process.And software SPSS 16.0 was used for statistics analysis.Results The plasma DAO activity in group G was significantly lower than that in group CPB(P <0.05),even though compared with group SH,the DAO activity in group G and CPB were significantly increased (P < 0.05).The activity of DAO in tissue homogenate in group G and CPB were decreased more significantly than that in group SH(P < 0.05),but there was no difference between group G and CPB (P =0.065).The plasma concentrations of D-lactate and LPS in group G were significantly lower than that in group CPB (P < 0.05),and the plasma concentration of D-lactate and LPS in both group G and CPB were markedly enhanced compared with group SH(P < 0.05).Conclusion Precondition with alanyl-gluamine dipeptide can decrease the permeability of gut mucosa,and might be a new way to protect the intestinal barrier function during cardiopulmonary bypass.

Objective To study the feasibility and safety of interventional closure for the treatment of infant’s perimembranous ventricle septal defect (PmVSD). Methods During the period from Jan. 2012 to Jan. 2013, a total of 229 single PmVSD infants less than three years of age were admitted to authors ’ hospital. The infantile patients were divided into intervention group (n = 88) and surgery group (n = 141). Patients in the intervention group underwent interventional closure procedure , while patients in the surgery group received conventional cardiac surgery. The operation success rate , the main and minor complication rates, the operation time, the postoperative hospitalization days, the incidence of postoperative pulmonary infection and the medical cost were recorded , and the results were compared between the two groups. Results No statistically significant differences in the operation success rate, the main complication rate, the postoperative hospitalization days and the medical cost existed between the two groups (P > 0.05). But the minor complication rate and the operation time of the intervention group were better than those of the surgery group. In the surgery group, the minor complication was mainly the respiratory infection, which was manifested as higher leukocyte count, higher C-reactive protein level, higher myocardial damage marker level as well as higher vasoactive drug scores in 24 hours after the operation , and the above items were significantly higher than those in the intervention group. Conclusion For the treatment of infant’s perimembranous ventricle septal defect, percutaneous transcatheter closure is clinically feasible. This technique is safe and reliable with obvious advantages when the indication is strictly observed and the procedure is carefully manipulated. This treatment can partly replace the conventional surgery.
