Objective To invesgate the safety and efficacy of the second generation biodegradable polymer Cobalt-Chromium sirolimus-eluting stent (EXCEL2) stent in diabetic patients by a subgroup analysis of of the CREDITⅡand CREDIT Ⅲ trials. Methods All patients who were implanted with the EXCEL2 stent were enrolled in the CREDITⅡand CREDIT Ⅲ trials. The primary endpoint was target lesion failure at 24-month, defi ned as a composite of cardiac death, target vessel myocardial infarction (TV-MI) and target lesion revascularization(TLR). The secondary endpoint was endpoints including all-cause death, all myocardial infarction (MI) or any revascularization.Results A total of 828 patients were included from the patients who were implanted with the EXCEL2 stent in the CREDIT II and CREDIT Ⅲ trials. 24-month follow-up rate was 99.5%. There was no significant difference in the primary endpoint (P>0.05) and event rates of the secondary endpoints(P>0.05) between the diabetic and non-diabetic group, which included all-cause death[diabetics (2.5%)vs.non-diabetics(1.4%),P>0.05],myocardial infarction(MI)(7.5% vs.5.0%,P>0.05),all from of revascularization(5.0% vs.3.9%,P>0.05),and stent thrombosis(0.6% vs.0.4%,P>0.05).Conclusions EXCEL 2 stent met the objective performance goal on effcacy and safety, which can reduce make stent restenosis, target vessel revascularization ,with 160 diabetic cases among them, and stent thrombosis in diabetic patients.

OBJECTIVETo investigate the effects of a new anticoagulant, annexin V derivative (AND) on anticoagulation and antithrombosis.

METHODSHigh and low doses of AND were given to rabbits (groups 1 and 2 respectively) by intravenous (iv) bolus injections followed by half the respective AND doses by iv infusion over 2 hours. Control groups were iv given heparin (group 3) and saline (group 4) of the same volume and procedure as that in group 1 and 2. Blood cell count, activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and fibrinogen level were examined before and 15, 30 and 60 min after iv bolus and 2 hours after the end of iv infusion. A 3.0 mm x 15 mm balloon was put into femoral artery to induce endothelial denudation 15 min after IV bolus and the blood pressure of femoral artery was monitored until the pulse pressure recorded 0 mm Hg when the vessel was occluded completely by a thrombus. The femoral arteries were collected and the thrombi were stripped off for measuring their lengths, wet and dry weights.

RESULTSAnticoagulation parameters: APTT at 15 min after iv bolus in AND group was significantly longer than that in group 4 (P < 0.05) but shorter than that in group 3 (P < 0.05); APTT and TT in group 3 were significantly longer than those in groups 1, 2 and 4. Fibrinogen: 0.70 mg/kg AND may decrease fibrinogen. Antithrombosis values: the wet and dry weights in AND groups were significantly lighter than those in group 3 and 4 (P < 0.05). The dry weight in high-dose AND group was remarkably lighter than that in low-dose group (P = 0.029). The length of thrombus in low-dose AND group was remarkably shorter than that in group 4 (P = 0.013), but not for group 3 (P > 0.05). It was remarkably shorter in high-dose AND group than in both group 3 (P < 0.001) and 4 (P = 0.015). The time when pulse pressure equaled to 0 was longer in AND group than in group 4 (P < 0.05), but not in 3.

CONCLUSIONAND is an effective anticoagulant and antithrombosis agent, the highest anticoagulation effect occurs at 15 min after IV bolus. Its anticoagulation effect is not more potent than that of standard heparin, while antithrombosis capacity is more effective. AND in treating thrombosis clinically might be promising.

OBJECTIVETo investigate the effects of the flexible surgical approaches on therapeutic and cosmetic outcomes of facial nevi.

METHODSFrom August 2002 to January 2008, 16 cases with facial nevi had been treated in our wards with the selected approaches. Surgical approaches including serial excision or one-time radical excision, free skin graft, and expanded flap were adopted in accordance with the individual size and location of the facial nevi.

RESULTSAll cases experienced complete excision and had satisfactory cosmetic appearance in the end.

CONCLUSIONThe flexible surgical measures help to minimize the risk of malignant transformation and achieve good cosmetic results.

OBJECTIVETo investigate the findings of contrast-enhanced multislice computed tomography (MSCT) that characterize intraductal papillary neoplasms of bile ducts (IPNB).

METHODSThe MSCT findings and clinical data of 16 cases of IPNB proven by surgical pathology were reviewed retrospectively.

RESULTSAmong the 16 cases, nine were adenoma (multi-lesions, n = 5; single lesions, n = 4) and seven were adenocarcinoma (multi-lesions, n = 4; single lesions, n = 3). Among the nine adenoma cases, seven showed nodules or masses in the expanding intrahepatic bile ducts with asymmetrical low density on plain scan, and two showed obvious expansion of biliary ducts and the inner wall of bile ducts was rough. All seven of the adenocarcinoma cases showed nodules or masses in the expanding intrahepatic bile ducts with asymmetrical low density-like adenoma. When contrast enhancement was applied, the nine adenoma cases manifested slight-to-moderate degrees of asymmetrical enhancement. For the seven adenocarcinoma cases, two showed asymmetrical enhancement similar to that of the adenoma cases and five showed continued enhancement; one case showed malignant infiltration of the bile duct and evident damage in the adjacent hepatic tissue. The CT plain scan findings for the two groups (adenoma and adenocarcinoma) were not significantly different (t = -1.17, P = 0.2632). Significantly different findings were obtained with the MSCT imaging analysis for the arterial phase (t = 6.53, P less than 0.01) and the portal vein phase (t = 5.63, P less than 0.01). All cases showed asymmetrical expansion of intrahepatic biliary ducts, diffuse or local, and four cases showed moderate expansion of the common bile duct. One adenocarcinoma case showed intumescence in the celiac lymph node by moderate asymmetrical enhancement.

CONCLUSIONMSCT is helpful for the differential diagnosis of IPNB from other hepatic lesions.
