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.

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.

Aim To investigate the effect of Dicranostiga Leptodu (Maxim) Fedde (DLF) on experimental liver injury induced by Calmette Guerin bacillus vaccine (BCG) and Lipopolysaccharide (LPS) in mice. Methods Experimental liver injury was induced by Calmette Guerin bacillus vaccine and Lipopolysaccharide in male mice by injecting via tail vein (50 ?g?kg -1 ), and administering LPS (10 ?g?mouse -1 ) 10 d later. Therapeutic groups were given respectively with DLF (0 5,1 0,2 0 g?kg -1 ) before administration of LPS. The level of ALT, AST and LDH and the concentration of ALB and GLB in serum were measured by automatic biochemistry analyzer, and MDA in liver plasma was measured by TBA method and the level of SOD was measured by pyrogallol auto oxidation method. Pathological morphological changes in liver tissue were observed. Results The three experimental groups were found with significant decrease in the elevation of serum GPT and LDH level and the content of MDA in the liver plasma. The liver tissue damages were also ameliorated. Conclusion DLF has protective effect against the experimental liver injury induced by BCG and LPS in mice.

Objective To observe the effects of estrogen on behavior and 5-HT in periaqueductal gray (PAG)in migraine model rats. Methods Tewnty-four ovariectomized Wistar rats were divided randomly into four groups:control group (Group A),migraine group(Group B),low dose estradiol-treated ovariectomized group(Group C),high dose etradiol-treated ovariectomized group(Group D).After 1 week,the rats in Group B,C and D were injected with nitroglycerine 10 mg?kg-1 subcutaneously to make migraine rat models,the rats in Group A were given peanut oil alike,and the behavior changes were observed.2 h after injection,the rats were killed and the midbrains were separated and then 5-HT immunohistochemical staining was performed.Results Behavior: compared with Group B,the degrees of red-calws,red-ears and red-tail rats in Group D relieved obviously,the times of climbing hutch and scratching head were much fewer,while the rats in group C showed no significant difference;Immunohistochemical staining:compared with Group A,the 5-HT-positive neurons expression in PAG of Group B and C were more obviously(P

Objective To compare the curative effect of laparoscopic and laparotomic operation for elderly Chinese women with cervical cancer. Methods The randomized controlled trials (RCT) and case controlled trials (CCT) were collected by searches of WanFang database, CNKI, VIP, China Biology Medicine (CBM) , PubMed. Data were extracted from these trials and data analysis was performed by RevMan 5.2.9. Results There were no RCTs, however, a total of 10 CCTs met the inclusion criteria and had data extracted for this review. The baseline characteristics of the laparoscopic group were similar to those of the laparotomic group. Comparing to laparotomic group, the laparoscopic group have longer operation time (MD =32.60, 95%CI: 5.65~59.55, P = 0.020), less amount of bleeding (MD = -94.01, 95%CI: -130.65 ~ -57.37, P = 0.000), smaller number of lymph node dissection(MD = 1.69, 95%CI: 0.67 ~ 2.72, P = 0.001), earlier anus exhaustion (MD=-17.09, 95%CI: -21.19 ~ -12.98, P = 0.000) and shorter hospital stays (MD = -4.30, 95%CI: -5.57 ~ -3.02, P = 0.000). There was significant difference between the two groups. But there was no statistical significance in postoperative indwelling catheter time (MD = -0.67, 95%CI: -1.92 ~ 0.58, P = 0.290) and surgical complications incidence (OR=0.62, 95%CI: 0.27 ~ 1.42, P = 0.260) between the two groups. Conclusion Laparoscopic management has the advantages of less traumatic and recovered quickly, and did not increase the incidence of complications. Laparoscopic operation is an ideal procedure for elderly Chinese women with cervical carcinoma.

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.
