Objective To observe and discusses the application of larger-bore autologous arteriovenous fistula as dialysis pathways in diabetes patients with chronic renal failure. Methods 86 cases of diabetic patients with chronic renal failure were divided into elderly group and non-elderly group. The patients within each group were assigned randomly into Experimental subgroup and control subgroup. Patients underwent wrist autogenous arteriovenous fistula angioplasty.The surgical method was end to side anastomosis between cephalic vein and radial artery. Vertical incision on the radial artery is about 0.7 cm-0.8 cm in the control subgroup and vertical incision on the radial artery is about 1.0 cm-1.1cm in the experimental subgroup. Results The success rate of the operation in experimental subgroup(90.9%, 95.2%) was significantly higher than that of control group(77.3%, 85.7%). The differences were significant (P<0.05). There was no heart failure in the patients underwent surgery. Conclusions In diabetes patients with chronic renal failure need autogenous arteriovenous fistula angioplasty. Properly increasing the diameter of anastomosis can meet the demand on blood flow of hemodialysis without increase complication of heart failure.

Vascular surgery is a new and course crossing medical science and has developed rapidly in recent years.The patients of vascular surgery have become more and more and are usually diagnosed incorrectly,so we should put emphasis on vascular surgery teaching and take advantage of multimedia,real demonstration and so on.

The quality management of drug research,development,registration,production and marketing strengthened by good practice for pharmaceuticals ensure the drag safety,effectiveness and quality control.Teaching of new drug research and evaluation in compliance with good practice for pharmaceuticals will be of value in making teaching content close to actual work,extending the students'knowledge and training student's good habits in scientific study.

To provide theoretical and practical basis for the successful formulation design of physically-mixed inhalation dry powder of proteins and peptides, related references were collected, analyzed and summarized. In this review drug micronization technology and commonly used carriers for inhalation dry powder preparation were introduced. For proteins and peptides, supercritical fluid technology and spray-drying are more suitable because of their capabilities of keeping drug activity. Being approved by U. S. Food and Drug Administration, lactose has been extensively used as carriers in many inhalation products. Formulation and process factors influencing drug deposition in the lung, including carrier properties, drug-carrier ratio, blending order, mixing methods, mixing time and the interaction between drug and carrier, were elucidated. The size, shape and surface properties of carries all influence the interaction between drug and carrier. Besides, influence of micromeritic properties of the dry powder, such as particle size, shape, density, flowability, charge, dispersibility and hygroscopicity, on drug deposition in the lung was elaborated. Among these particle size plays the most crucial role in particle deposition in the lung. Moreover, based on the mechanisms of powder dispersity, some strategies to improve drug lung deposition were put forward, such as adding carrier fines, adding adhesive-controlling materials and reprocessing micronized drug. In order to design physically-mixed inhalation dry powder for proteins and peptides with high lung deposition, it is essential to study drug-carriers interactions systematically and illustrate the potential influence of formulation, process parameters and micromeritic properties of the powder.

ObjectiveTo investigate the expression of TESTIN gene in endometrial carcinoma and explore the functions of this gene in tumor development and progression.MethodsqRT-PCR and immunochemical staining assay were used to determine the mRNA and protein level of TESTIN in the tumor tissues,and the relationship between TESTIN expression and clinical pathology characteristics was analyzed.Results Compared to normal tissue,76.5％ (52/68) tumor tissues showed TESTIN reduced ( P ＜ 0.01 ),furthermore,this reduction in the subgroup of endometrioid adenocarcinoma was significant,but it was rarely observed in the subgroup of serous papillary adenocarcinoma.ConclusionsTESTIN was obviously down regulated in endometrail carcinoma,especially in endometrioid adenocarcinoma,which indicated TESTIN played an important role in tumorigenesis of uterine.

Objective To investigate the factors that related to acute biliary pancreatitis including size and the location of the common bile duct stone. Methods Clinical data from 3497 patients with common bile duct stone admitted to the hospital between Jan. 2002 and Dec. 2008 were retrospective analyzed. All patients were grouped according to the size and the location of the bile duct stones. The incidence of acute pancreatitis was compared among groups. Results In patients with common bile duct stone accompanying the acute pancreatitis,common symptoms were fever, bellyache and jaundice, as well as elevated serum amylase. There was a negative correlation between size of the common bile duct stone and the severity of acute hiliary pancreatitis, which was easily induced by the stone in the Vater's ampullar or distal common bile duct. Conclusion Early endoscopic treatment should be carried out in patients with microlith located in the Vater's ampullar or distal common bile duct in order to prevent the acute biliary pancreatitis.

Objective To explore the long-term efficacy of endoscopic sphincterotomy (EST) for choledocholithiasis and to evaluate the necessity of cholecystectomy after EST. Methods Two hundred and fifty seven patients who underwent EST for choledocholithiasis in 2006 were followed up for an average period of 34. 8 months (26-48 months). According to the existence of cholecystolithiasis, the patients were divided into group A (combined with cholecystolithiasis, n = 151) and group B (without cholecystolithiasis, n = 106) , and group A was further divided into group A1 as undergoing cholecystectomy after EST (n =56) and group A2 as not having cholecystectomy after EST ( n = 95). Results Of the 257 patients, late complications occurred in 31 patients (12. 1% ) , including recurrent choledocholithiasis in 25 (9.7% ), cholangitis in 27 (10. 1% ) , acute pancreatitis in 2 (0. 8% ) and cholangiocarcinoma in 1 (0.4% ). The rates of late complications and recurrent choledocholithiasis were significantly higher in group A2 than those in group A1 (P<0.05). Conclusion EST is safe and effective for choledocholithiasis. Cholecystectomy after EST is necessary in patients with cholecystolithiasis.

Objective To estimate the long-term efficacy of endoscopic sphincterotomy (EST)in treatment of choledocholithiasis and to analyze the potential risk factors for disease recurrence.Methods A total of 154 patients with choledocholithiasis,who underwent EST between January 2006and December 2006, were enrolled. Multivariate analysis was used to evaluate the association of clinical features and experimental parameters with recurrence of choledocholithiasis. Results Longterm complications developed in 22 patients (14.29%) including recurrent choledocholithiasis (18/154,11.69 % ) and combined cholangitis (16/154). Cholangitis without calculi was found in 1 case (0.65%), acute pancreatitis in 2 cases (1.30%) and cholangiocarcinoma in 1 case (0.65%). High body mass index and serum cholesterol were proved to be risk factors for recurrence of choledocholithiasis. Whereas the incision size (0.5 cm-1.5 cm) of vater's papilla was the protective factor for recurrence of choledocholithiasis. Conclusions Body mass index, serum cholesterol and the incision size of vater's papilla are related to recurrence of choledocholithiasis.
