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.

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.

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.

Purpose To investigate the diagnostic value of fetal echocardiography in total anomalous pulmonary venous connection (TAPVC),and to analyze the reasons ofmisdiagnosis so as to improve accuracy of prenatal diagnosis.Materials and Methods The prenatal echocardiographic data of 24 cases of TAPVC confirmed by postnatal echocardiography and prenatal MRI from October 2001 to December 2015 in Children's Hospital Affiliated to Nanjing Medical University and Shanghai Children's Medical Center Affiliated to Shanghai Jiaotong University School of Medicine were retrospectively analyzed.Results In 24 cases,there were 14 fetuses of supracardiac type,7 cases of intracardiac type,2 cases of infracardiac type,and 1 case of mixed type.15 fetuses had TAPVC only,whereas 9 cases were associated with other cardiovascular anomalies,most commonly including bilateral right atria,single atrium,single ventricle,common atrioventricular valve and pulmonary stenosis.On 4-chamber views,the common sonographic sign was absent of pulmonary venous return to the left atrium in 24 cases (100.0％),and the presence of venous confluence between left atrium and descending aorta was observed in 22 cases (91.7％).In all 24 cases,1 case was missed diagnosis,and 3 cases were misdiagnosed as persistent left superior vena cava,common pulmonary vein atresia and patent left atrial cardinal vein.Conclusion TAPVC can be accurately diagnosed by fetal echocardiography,but it is prone to be misdiagnosed.
