Objective To investigate the role of O-linked N-acetylglutamine (O-GlcNAc) modification in glutamine-induced myocardial heat shock protein (HSP70) expression in a rat model of endotoxic shock. Methods Thirty-two 8 weeks old male SD rats weighing 250-300 g were randomly divided into 4 groups (n = 8 each):group Ⅰ control (group C); group Ⅱ LPS; group Ⅲ G+ LPS and group glutamine + LPS (group A + G + LPS). Endotoxic shock was induced by iv administration of LPS 10 mg/kg in group Ⅱ , Ⅲ and Ⅳ.Glutamine 0.75 g/kg was administered iv at 1 h before iv LPS in group Ⅲ and Ⅳ . Alloxan (an inhibitor ofO-linked N-acetylglucosamine transferase) 50 mg/kg was administered iv together with glutamine at 1 h before LPS in group Ⅳ. The animals were sacrificed at 6 h after iv LPS administration. Their hearts were removed for determination of the expression of O-GlcNAc and HSP70 in myocardium. Results Intravenous LPS significantly up-regulated the expression of O-GlcNAc and HSP70. Glutamine pretreatment further increased the expression of O-GlcNAc and HSP70. The glutamine pretreatment induced increase in O-GlcNAc and HSP70 expression was abolished by concomitant administration of alloxan. Conclusion O-GlcNAc modification may be involved in glutamine-induced myocardial HSP70 expression in endotoxic shock.

OBJECTIVETo evaluate the safety and effectiveness of Shengji Ointment (SO) (by external use) in treating infective ulcer patients with yang syndrome (YS).

METHODSA multicenter, stratified, randomized controlled clinical study was used in this study. A random digit table was formed in the ratio of 3:1,440 infective ulcer patients of YS from 5 centers were recruited, 330 in the treatment group (external use of SO, exchange once every 24 h) and 110 in the control group (external use of Votalin, exchange once every 24 h). The therapeutic course consisted of 21 days. The ulcer area, wound depth, pain degree were observed before treatment at day 3, 7, 14, and 21, and safety indices monitored at the same time.

RESULTSThe ulcer area was significantly reduced in the treatment group after 21-day medication, obviously superior to that of the control group (P = 0.002). Ulcer areas at different time points were analyzed. From the 7th day of medication the reduced area was obviously less in the treatment than in the control group (P = 0.002). Besides, the longer the more obvious difference. Compared with the control group, the healing rate of ulcer area, the pain disappearance rate, and the healing rate of ulcer depth were all obviously improved in the treatment group (all P < 0.01). No adverse event occurred in the two groups.

CONCLUSIONSExternal use of SO was safe and effective in treating infective ulcer patients with YS. It could accelerate wound healing with better analgesic effect.

To study the effect of intraarterial bolus of recombinant human angiogenin (rhANG) on stimulating revascularization in a rabbit hindlimb ischemic model,the limb ischemic model was induced by ligation and excision of every branches of the femoral artery in 28 rabbits. On the 11th day after operation, various doses of rhANG (0,5,20 and 40 ? g) as a single bolus were administered intraarterialy via the catheters inserted into the bifurcation of the iliac artery. Revascularization and perfusion of the ischemic limb were compared in each animal postoperatively by using 99 Tc MAA perfusion scan, serial angiography and thigh muscle biopsy. Rabbits in the 20?g group and the 40?g group had significantly better revascularization and blood perfusion than the control group and the 5?g group.It is concluded that rhANG can promote blood purfusion, revascularization and recovery.

To assess the principles of diagnosis and management of Klippel Trenaunay Syndrome (KTS), ascending venography and PPG were used as the means of diagnosis for KTS. 18 cases received nonoperative therapy with elastic bandages or stockings, and 26 patients were operated on, including stripping of varicose vein, decompression of popliteal vein and segmental transplantation with valve to femoral or popliteal vein. The effective rate in the operative group was 73.1% (19/26),whereas the illness of 18 patients was stable with elastic support. Thirty one of 44 patients have been improved during 1～10 year follow up period . It is important that the indications and styles of operation must be carefully considered according to the clinical manifestations and venogram.

To assess the principles of perioperative management and prevention and treatment of postoperative complications of extracranial carotid artery aneurysm(ECAA),15 patients with ECAA received surgical treatment between 1988 and 2000.Among them,11 patients underwent aneurysmectomy with artery reconstruction,3 had resection of aneurysm and ligation of external carotid artery, and the other patient had aneurysmorrhaphy. No postoperative deaths or severe complications occurred except one patient with Horner's syndrome.Satisfactory results were achieved in 7 out of 8 patients within a 6 month to 7 year follow up period. The results showed that aneurysmectomy with artery reconstruction is a best operative procedure for extracranial carotid artery aneurysm. In order to prevent severe complications,such as brain ischemia and injury of cranial nerves, intensive perioperative management must be emphasized.

This paper is to summarize our experiences in the operation indication and management of perioperative complications in treatment of Stanford B aortic dissection by using endovascular graft exclusion (EVGE). 32 patients underwent the procedure of EVGE . Various sizes of tubular grafts were introduced over the entry tear of aorta via the femoral artery. The procedure was technically successful in all patients. No Severe complication occurred during the perioperative period except one death due to heart infarction. These preliminary results suggest that EVGE is safe and efficient for Stanford B aortic dissection. EVGE is a method of first choice for the patients with this disease.

Objective To investigated the distribution of intraluminal thrombus (ILT) in abdominal aortic aneurysms (AAAs), and to examine the influence of age, gender and aneurysm diameters on the ILT formation. Methods Morphological analysis of ILT in AAA of 103 consecutive patients was undertaken with helical CT angiography. ILT shape, distribution and thickness of ILT were recorded and analyzed in correlation with age, gender and aneurysm diameters. Results ILT were found in 66.9% of all the patients. ILT was always situated in the area away from the main axis of AAA. The incidence of ILT in female group (n=13) was much lower than that in male group (n=90) (15.5% vs 77.4%, P
