Objective Functional vein end to arterial side (ETS) anastomosis uses vein side to arterial side (STS) anastomosis with distal vein ligation, which can achieve similar effects as those of ETS after STS anastomosis. The purpose of the study was to provide a meta-analysis to compare the clinical outcomes between traditional and functional ETS anastomosis in radiocephalic fistula for dialysis access. Methods Databases including PubMed, EMbase, the Cochrane Library, CNKI, Wanfang database were searched from the inception to February 6, 2020. Eligible studies comparing traditional and functional ETS anastomosis in radiocephalic fistula were included. Data were analyzed using Review Manager Version 5.3. Results Seven studies were included in the meta-analysis. Five randomized controlled trials and two cohort studies involving 841 patients were identified. Compared with traditional ETS anastomosis, functional ETS anastomosis had shorter anastomosis time (MD − 9.54, 95% CI − 17.96 to − 1.12, P = 0.03), higher surgical success rate (OR 3.80, 95% CI 1.76–8.22, P P P = 0.03), higher patency rate after 6 months (OR 1.90, 95%CI 1.09–3.31, P = 0.02), higher patency rate after 12 months (OR 1.70, 95% CI 1.09–2.66, P = 0.02). There was no difference after the two arteriovenous (AVF) anastomosisl methods concerning AVF maturation time (SMD − 0.48, 95% CI − 1.30–0.34, P = 0.25) and patency rate after 1 month (OR 1.77, 95% CI 0.65–4.80, P = 0.26). Conclusion Functional ETS anastomosis had advantages of easy operation, high surgical success rate, few complications, high patency rate of 3 months and long-term, but did not have obvious advantage in the early stages concerning AVF maturation time and 1-month patency rate.

Objective: The objective of this meta-analysis was to compare the efficacy and safety of tacrolimus (TAC) monotherapy versus TAC-corticosteroid combination therapy in idiopathic membranous nephropathy (IMN) patients. Methods: Databases including PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang database were searched from inception to January 10, 2021. Eligible studies comparing TAC monotherapy and TAC-corticosteroid combination therapy in IMN patients were included. Data were analysed using Review Manager Version 5.3. Results: Seven studies were included in the meta-analysis. One randomized controlled trial and six cohort studies involving 372 patients were identified. Compared with TAC monotherapy, TAC-corticosteroid had a higher total remission at the sixth month (odd ratio (OR) 0.49, 95% confidence interval (CI) 0.31–0.78, P

Background: The objective of this study was to compare the complications of low-site peritoneal dialysis (PD) catheter placement and traditional open surgery in peritoneal dialysis catheter insertion. Methods: The following databases were searched from inception to September 6, 2019: PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang. Eligible studies comparing low-site PD catheter placement and traditional open surgery in peritoneal dialysis catheter insertion were included. The data were analyzed using Review Manager Version 5.3. Results: Seven studies were included in the meta-analysis. A total of 504 patients were included in the low-site PD catheter placement group, and 325 patients were included in the traditional open surgery group. Compared with traditional open surgery, low-site PD catheter placement had a lower incidence rate of catheter displacement (odds ratios [OR] 0.11, 95% CI 0.05–0.22, P

The aim of this study was to analyze the differences in the intestinal composition between normal individuals and colon cancer patients.To establish the criteria for screening a normal individual for colon cancer, human colonic biopsies were obtained at routine colonoscopy. For patients with colon cancer, samples were obtained from cancerous regions. For normal individuals, colonic biopsies were taken from 3 sites of large intestine (descending, transverse, and ascending colon). Thereafter, a comparison of the microbiota structure by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) was carried out. At last, bacterial species were identified by sequencing special bands from DGGE gels and comparing data with sequence databases.With PCR-DGGE, we have discovered that the diversity and richness of the bacterial community from colon cancer patient's colonic mucosa were lower than that of the normal individual's sample. Then, a special DGGE band was found in the colon cancer patients. After sequencing, we confirmed that it had a high level of similarity with bacteroides.Colon cancers are closely related with the alteration of intestinal flora such as the reduction of biodiversity and richness of the bacterial community. Furthermore, the increase in proportion of bacteroides may be directly associated with colon cancer.
