Objective To observe the clinical efficacy and adverse reactions of tissue-selecting therapy stapler with internal hemorrhoids.Methods Clinical and follow-up data of 110 cases with internal hemorrhoids undergoing tissue-selecting therapy stapler between March 2011 and March 2012 were retrospectively analyzed.The efficacy,adverse reaction and the complications were assessed.Results Of the 110 patients,Ⅱ degree hemorrhoids in 21 cases,Ⅲ degree hemorrhoids in 63 cases,Ⅳ degree hemorrhoids in 26 cases.The mean operation time was 18 minutes,range 15 to 25 minutes.The mean hospital stay time was 4 days,range 3 to 6 days.Of the 90 patients,urinary retention 9 patients (8.18％),anal bulge 41 patients(37.27％),fecal urgency 8 patients (7.27％),no other complications found,such as postoperative bleeding,anorectal stenosis and fecal incontinence.Recurrence rate was 4.55 ％ within a year follow-up.Conclusions Tissue-Selecting Therapy stapler for internal hemorrhoids is a simple and safe procedure with less intraoperative and postoperative bleeding,low recurrence rate,fewer postoperative complications and so on.It's worthy of clinic application.

Objective To investigate the effect of melatonin on serum malondialdehyde (MDA), NF-κB, tumor necrosis factor-α(TNF-α) andβ2-microglobulin (β2-MG) levels in secondary brain damage following intracerebral hemorrhage patients.Methods 90 patients secondary brain damage following intracerebral hemorrhage were divided into experimental group and control group, 45 cases in each group.The control group were given conventional treatment after surgical removal of hematoma, and the experimental group, on the basis of control group, were given melatonin capsule (6 mg melatonin) , orally, once a day, for 2 weeks treatment.The levels of MDA, NF-κB, TNF-αand β2-MG in patients’ serum were detected.Results The MDA, NF-κB, TNF-αand β2-MG levels after treatment significantly decreased compared with before treatment in two groups (all P<0.05), and the above indexes in experimental group significantly decreased compared with control group ( P <0.05 ).Conclusion Melatonin can significantly reduce the levels of MDA, NF-κB, TNF-αand β2-MG levels in brain injury patients with cerebral hemorrhage, and repair brain damage, which has a guiding significance for clinical use.

AIM: To explore the effects of oxidized low density lipoprotein (OxLDL) and one of its component— lysophosphatidylcholine (LPC) on cholesterol efflux from mouse macrophage foam cells. METHODS: (1) Cholesterol efflux induced by apoAI from mouse peritoneal macrophage foam cells loaded with OxLDL or acylated LDL(AcLDL) was measured. (2) Cholesterol efflux induced by LPC and apoAI from macrophage foam cells separated from normal or apoE gene deficient (E 0) mouse loaded with AcLDL were measured. RESULTS: (1) When the macrophage foam cells were incubated with apoAI, cholesterol efflux from AcLDL-induced macrophage foam cells increased significantly compared to that of OxLDL-induced macrophage foam cells. (2) LPC promoted cholesterol efflux from macrophage foam cells in relation to both dosage and time. When LPC was incubated with E 0 mouse macrophage foam cells, the released cholesterol mass was significantly lower than that of normal mouse macrophage foam cells. It was also found that cholesterol efflux induced by apoAI normally occurred in E 0 mouse macrophage foam cells. CONCLUSIONS: (1) OxLDL accumulated cholesterol in macrophages and impair cholesterol efflux. (2) LPC induced cholesterol efflux from macrophage foam cells, which may occur via apoE pathway.

To investigate the contents and distribution of matrix metallproteinases(MMP) in abdominal aortic aneurysm(AAA) on protein level, forty male Wistar rats were randomly divided into two groups, the rats of experimental group were perfused with pancreatic elastase in the isolated abdominal aorta to construct the model of AAA. Laparotomy was preformed on the 14th day after operation, the aortas were measured and harvested. The rats of control group were operated with the aortas harvested immediately. Immunohistochemical staining and computer image analysis were performed to analyze the contents and distribution of MMP 2 and MMP 9. The aortic diameter progressed to aneurysmal dimension in the experimental group. Immunohistochemistry study revealed that the MMP contents in AAA exceeded that in normal aorta obviously. The MMP 2 cotents in AAA tunica media were higher than MMP 9. It is suggested that MMP 2 plays the main role in extracellular matrix degradation of AAA tunica media.

To investigate the prevention and management of postoperative complications of lower extremity amputation for arterial occlusive diseases, a retrospective analysis was made in 18 lower extremity amputations which were performed on 14 patients from Jan 1996 to Dec 1999. The mean age of the patients was 72. Before opeoation,78 6% of the patients were complicated with coronary artery disease, 69.9% with high blood pressure and 78.6% with diabetes mellitus, 43.4% with vascular reconstruction history. 6 above the knee amputations, 7 below the knee amputations, 1 hemiterpene amputation and 4 amputations of the toes were performed. Postoperative myocardial infarction occarred in 2 cases, gangrene of the stump in 3 cases and infection in 1 case, the total incidence rate of complication was 33%. The results showed that lower extremity amputation is not a complex operation, but preoperative estimation of the level of amputation and postoperative intensive care can reduce the postoperative rate of complication.

Colonic ischemia is a well documented complication of abdominal aortic reconstruction. In this retrospective study of abdominal aortic aneurysm patients undergone endovascular graft exclusion, the incidence and management of this complication were investigated. From Mar 1997 to Apr 2000,among the 40 patients who received elective endovascular graft exclusion for,infrarenal abdominal aortic aneurysm the bilateral hypogastric artery was retained in 30 patients, the unilateral hyogastric artery was retained in 10 patients. One patient had lower abdominal pain on the 28th day after operation, CTA showed the bilateral hypogastric artery occlusion, the symptoms were relieved after drug treatment. Retaining unilateral hypogastric artery can prevent the colonic ischemia after endovascular graft exclusion for abdominal aortic aneurysm, the chronic colonic ischemia secondary to bilateral hypogastric artery occlusion can be relieved by effective drug treatment.

To investigate the diagnosis and treatment of Stanford B thoracic aortic dissection eomplicated with renal ischemia, 29 cases of Stanford B thoracic aortic dissection admitted from January 1996 to April 2000 were retrospectively studied. Three of them had renal ischemia secondary to aortic dissection (2 acute,1 chronic). One patient in acute stage died 3 days after onset, the other patient in acute stage complicated with bilateral lower extremity ischemia was treated with fenestration of intimal flap, and the symptom was relieved. The patient in chronic stage was treated with endovascular graft exclusion for aortic dissection and the renal ischemia was relieved because of the restored true lumen blood. The results showed that palliative bypass helps relieve symptoms and improve survival rate. For the chronic aortic dissection complicated with renal ischemia, endovascular graft exclusion can restore the true lumen blood and relieve renal ischemia.

This paper reviewed the development of vascular surgery in diagnosis and treatment in recent years,the concepts and specialty of Duplex scan,MRA, CTA were discussed,the progress and problems of traditional revascularization and endovascualr technique were analyzed.
