After completing the producing of the televised teaching material of TCM Bone-setting Skills,which was sponsored by Scientific and Teaching Section of Ministry of Health,and applying it to the teaching process in classroom for undergraduate students in Southern Medical University,The students were asked to fill out a questionnaire so as to preliminarily explore the applying methods and assess its teaching value under the circumstances of multimedia teaching.

In the study of T2DM(n=30),IGR(n=26) and NGT(n=30) cases in Guangxi Province,T2DM had higher resistin and PAI-1 levels than did the groups of IGR and NGT(P<0.05).IGR had higher levels of PAI-1 and leptin than NGT(P<0.05).Leptin level of T2DM was higher than that of NGT(P<0.05).Insulin resistance index was positively correlated with leptin,TG and PAI-1 levels(P<0.05).

Objective To study the effects of supra-physiologic glucose on the expression of PDX-1 and insulin secretion. Methods Islet cells isolated from SD rats were incubated in medium containing 5.6 mmol/L or 33 mmol/L glucose respectively for 3 days. Basic and glucose-induced insulin levels in supernate and in islet cells were detected. The PDX-1 mRNA and protein were detected. Results (1) Islet cells exposed to 33 mmol/L vs 5.6 mmol/L glucose for 3 days showed significant decrease in the basic and glucose-induced insulin release, and in cell insulin content and PDX-1 protein. (2) Prolonging incubation of islet cells in 33 mmol/L glucose aggravated the inhibitive effect on PDX-1 expression and insulin secretion. (3)Recovery to normal concentration of glucose in 3 days could partly improve PDX-1 expression and insulin secretion. Conclusions Inhibition of PDX-1 is one of the mechanism of glucotoxicity, and recovery to normal concentration of glucose in 3 days can partly improve PDX-1 expression and insulin secretion.

0.05). Accordingly, statistics shows that the mean value of PI is 2.56?2.35. Conclusion: The referential range of PI for Chinese CABG patients is 2.56?2.35.

Objective To introduce the clinical experience of Bentall procedure with composite tissue valve conduit. Methods Five patients were diagnosed as severe aortic regurgitation with dilatation of Valsava sinus and sinotubular junction and ascending aorta. Mean age of patients was (55.8?9.4) years (range 47～67). After median sternotomy , cardiopulmonary bypass was established using a single two-stage venous cannula. Temperature was brought to 28℃. After the ascending aorta was occluded, an aortotomy was made and aortic valve was excised. Aorta was removed from sinuses of Valsalva except for generous buttons around coronary ostia. After sizing the aortic annulus, an appropriate-size tissue valve and woven dacron conduit (3 mm greater in diameter than the tissue valve) were chosen to build a composite conduit. It was attached to annulus of aortic valve with pledget-reinforced horizontal mattress stitches to replace the aortic valve and ascending aorta as an en bloc procedure (Bentall procedure). In 2 cases, Coronary artery bypass grafting was performed with greater saphenous vein anastomosed distally to left anterior descending artery and proximately to conduit. Results All cases recovered uneventfully and they were discharged without any postoperative complications. Echocardiography was repeated before discharge. Mean aortic pressure gradient was (18.3?7.6) mmHg. Left ventricular dimension was significantly reduced [(58.8?6.3)mm vs. (43.7?3.1)mm]after operations(P0.05). Follow-up was 2 to 8 months. Conclusion With composite tissue valve conduit, Bentall procedure to replace the aortic valve and ascending aorta as an en bloc procedure is feasible and safe for the elderly patients. A long-term follow-up for the function and structure of tissue valve is needed.

65mmHg. Sufficient blood products might be indicated when there was excessive oozing. Anticoagulant was not necessary. Two patients died of perioperative myocardial infarction and one of allergic shock to protamine. An incidence of postoperative complications as low as 2 2% (5/225) was obtained. Five patients were found to have various postoperative complications, which were completely cured. All the rest patients were uneventful, and they were discharged after (3 0?2 6) days of stay in the ICU and (8 2?1 5) days after the operation. Therefore, it is our belief that comprehensive and careful postoperative management is essential to achieve excellent results.

To introduce the experience in application of intra aortic balloon pump (IABP) in coronary artery bypass grafting (CABG), 506 consecutive CABG performed from March 1997 to October 2001 including 19 cases who needed IABP support were retrospectively studied. IABP was inserted through femoral artery when blood circulation failed to maintain normal even though cardiopulmonary bypass had been weaned off and inotropic agents administered. The overall rate of using IABP was 2 4%. IABP was not needed in off pump CABG. Sixteen patients smoothly resuscitated from low output syndrome, but two died of perioperative myocardial infarction (PMI) and one of allergic shock to protamine, resulting in a mortality rate of 15 8%. Two patients (10 5%) were respectively insulted by external iliac artery rupture and thromboembolism of dorsal pedis artery but cured completely. The complication rate was 10 5%. The mean duration of using IABP was 25 3?5 6 hours. The authors hold that IABP should be used without hesitation when indicated and good early outcome and low incidence of complication can always be obtained.

ObjectiveTo determine the primary control factors of nucleotides metabolisms on insulin secretion.MethodsNMRI mice isolated islets were used to investigate the amount of insulin secretion and the changes of ATP,ADP,GTP,GDP and UTP in islets when the activity of K+ATP channel was eliminated by diazoxide.ResultsThe above assays demonstrated that insulin secretion increased with the rise of glucose concentration.In the same time,ratio of ATP/ADP,GTP/GDP and level of UTP increased,too.All three indexes correlated with the insulin secretion very well respectively,but only ratio of ATP/ADP can control insulin secretion directly in common influence.ConclusionOur findings suggest that there is the second control site in islets when glucose induces insulin secretion and ATP/ADP ratio is only key factor in this mechanism.
