Objective To Compare postoperative complications between patients with varicose veins of the lower limbs treated with foam sclerotherapy or endovenous laser.Method From 2011 to 2015,simple varicosis of great saphenous vein patients (grade C3-6) in 2 542 cases,3 468 limbs were divided into 2 groups.Combined with high ligation of great saphenous vein plus stripping,foam sclerotherapy group (1 355 cases) underwent calf foam sclerotherapy (1% polidocanol),endovenous laser group (1 187 cases) underwent endovenous laser therapy.All postoperative patients were treated with stretch socks for 3 months.Postoperative pain (calf),deep vein thrombosis,pulmonary embolism,superficial thrombophlebitis,saphenous nerve injury,ecchymoma,migraine,allergic dermatitis,pigmentation in 2 groups were compared.Result During the follow-up,28 cases in foam sclerotherapy group had saphenous nerve injury (2%),1 071 (79.1%) cases had subcutaneous ecchymosis,613 cases (51.6%) in endovenous laser group had saphenous nerve injury,979 cases (82.5%) had subcutaneous ecchymosis,8 cases (1.0%) had skin burns (x2 =824.660,4.786,9.161,P < 0.05).Endovenous laser group (23.8%) was significantly better than that of foam sclerotherapy group (30.8%) in pigmentation (x2 =15.243,P <0.05).Conclusion Treatment of varicose veins of the lower leg with foam sclerotherapy has less postoperative complications compared with endovenous laser.

Objective To determine the expression profile of serum microRNAs(miRNAs) in early-onset familial Alzheimer's disease (EO-FAD) patients. methods miRNA microarrays were performed to detect the expression profile of serum miRNAs in 2 cases of EO-FAD patients,2 cases of EO-FAD carriers and 2 cases of normal controls.Preliminary bioinformatic analysis was conducted. Result sIt was found that 21 miRNAs were up-regulated and 22 miRNAs were down-regulated in serum of EO-FAD patients,the differences were statistically significant(P<0.05).miR-5704(P=0.0002),miR-4639-3p(P=0.0195),miR-107(P=0.0204) were markedly up-regulated,miR-5572(P=0.0008),miR-204-3p(P=0.0014),miR-542-5p(P=0.0106) and miR-155-5p(P=0.0240) were markedly down-regulated.Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis suggested that the dysregulated miRNAs may be involved in the mechanism of EO-FAD by affecting neurotrophin signaling pathway.Conclusion miR-5704,miR-4639-3p,miR-107,miR-5572,miR-204-3p,miR-542-5p and miR-155-5p may be used as potential biomarkers of EO-FAD,and involved in the mechanism of EO-FAD by affecting neurotrophin signaling pathway.

Objective To report the primary experience of open placement of triple-branched stent graft for acute Stanford type A aortic dissection. Methods Between June 2008 and September 2009, 20 well-selected patients with acute Stanford type A aortic dissection underwent open placement of triple-branched stent graft for total arch reconstruction. When core cooling to a 20℃ nasophageal temperature, perfusion to the lower body was discontinued and the ascending aorta was transected at the base of the innominate artery. Through a transverse incision, the triple-branched stent graft was inserted into the true lumen of the arch and descending aorta, and each side arm of the stent graft was positioned one by one into the arch branches.The transected stump of the ascending aorta was reconstructed by inner proximal stent-free dacron tube of the main graft and outer teflon felt, and subsequently continuous anastomosis to the 1-branched dacron tube graft was made. Results Open placement of triple-branched stent graft was technically successful in all patients. The mean cardiopulmonary bypass time, aortic cross-clamp time and lower body arrest time were (163.2 ±19.2) min, (89.4 ±10.0) min and (32. 7 ±6. 6)min, respectively. Transient postoperative neurological dysfunction was observed in 1 patient and acute renal failure in 1 patient. All patients were discharged from the hospital. Their computed tomographic scans at 3 months postoperatively showed that all stent grafts were fully opened without distortion. In the vascular stent implantation site the dissected false lumen was eliminated. The false lumen of the descending aorta distal to the stent graft was closed with thrombus in 16 cases. Conclusion Open placement of triple-branched stent graft is a new effective technique for total arch reconstruction in acute type A aortic dissection. Patients have the indications of the extensive primary repair of the thoracic aorta without primary intimal tears in the arch may be the best candidates for this new technique. The size of the stent graft, the distances between two neighboring side arm grafts and the prevention of the intimal trauma during the placement are crucial for successful open placement of triple-branched stent graft.

Objective:To conduct a meta-analysis of clinical data to investigate the relationship between incretins and fracture in order to provide individualized hypoglycemic agents for type 2 diabetic patients with osteoporosis.Methods:PubMed, Embase, Web of Science, and Cochrane databases were searched up to January 1, 2018 for randomized controlled trials(RCTs)and the relationship between incretins and fracture was explored by meta-analysis.Results:The meta-analysis showed that the use of incretin was not associated with fracture risk compared with placebo or other positive hypoglycemic agents( OR 0.972, 95% CI 0.876-1.079). But in the subgroup analysis, 100 mg/d sitagliptin( OR 0.495, 95% CI 0.304-0.806)or 1.8 mg/d liraglutide( OR 0.621, 95% CI 0.413-0.933)reduced fracture risk. Conclusions:Meta-analysis shows no increase in the incidence of fracture events after the use of incretin. 100 mg/d sitagliptin or 1.8 mg/d liraglutide may exert protective effects on bone metabolism. However, the included data are from the reports of fracture adverse reactions in RCT studies, and large-scale clinical studies are needed to confirm these findings.
