Objective To evaluate the feasibility and efficacy of endoscopic push?radial dissection (EPRD)for benign esophageal stricture(BES). Methods Clinical data of 24 patients diagnosed as having BES who received EPRD were analyzed. The procedure and efficacy were evaluated. Results All 24 patients underwent EPRD successfully with mean operation time being 32 min(15?45 min).The mean esophageal stric?ture incision length was 3?? 2 cm (1?? 0?8?? 0 cm).No severe complications related to EPRD occurred, or trans?ferred for surgery. Patients were followed up for 1?5 months (mean 2?? 8 months). Dysphagia was relieved signif?icantly during the follow?up in 23 patients where endoscopy could go through smoothly. But dysphagia re?oc?curred in one patient 2 weeks after the operation, who underwent a second EPRD and stent implantation, then dysphagia was relieved. Conclusion EPRD is safe, feasible and effective for benign esophageal stricture.

To evaluate the efficacy and feasibility of bipolar electrocoagulation in the treatment of gastric antral vascular ectasia(GAVE). Six patients with GAVE who underwent gastroscopy and bipolar electrocoagulation between January 2018 and December 2019 in the Affiliated Hospital of Medical School of Ningbo University were included in the study.The operation and clinical response were observed. All the 6 patients underwent bipolar electrocoagulation successfully. The mean operation time was 32 min (range 25-45 min). Mean number of sessions required for eradication of GAVE was 1.17. No severe complications related to endoscopic treatment occurred. There was no recurrence of GAVE at a mean time of 10.8 months (range 2-25 months) of follow-up. Stabilization of hemoglobin levels and decrease in blood transfusion requirements along with endoscopically complete or near-complete eradication of GAVE were observed in all patients during the follow-up.Bipolar electrocoagulation in the treatment of GAVE is effective, safe, and simple.

Objective To evaluate the feasibility and clinical effects of percutaneous endoscopic technique in treating multi-segmental lumbar spinal stenosis in the elderly.Methods Thirty elderly patients with multi-segmental lumbar spinal stenosis and an indefinite positioning of duty segments were retrospectively analyzed.Based on treatment mode of the stenotic segment of lumbar spine,all patients were divided to two groups.The segments of lateral recess or foraminal stenosis were treated with percutaneous endoscopic decompression via the transforaminal approach,while the segments of central stenosis were treated with percutaneous endoscopic decompression via the interlaminar approach.Results Twenty-seven (90%) patients were treated in double segments and three patients (10%) were treated in three segments.There were significant improvements in Visual Analogue Scale,Japanese Orthopaedic Association and Oswestry disability index scores at 3 day and 1 year after therapy as compared with pre-therapy (both P < 0.05).Conclusions Percutaneous endoscopic technique is safe and effective in the treatment of elderly multi-segmental lumbar spinal stenosis.

Objective:To investigate the impact of cleavage factor Im25(CFIm25)on VSMCs-specific knockdown in the context of hyperlipidemia.Methods:Mice models were constructed with specific knockout of CFIm25 in VSMCs(CFIm25f/+ TaglnCre)and control mice(TaglnCre).The mice were fed a normal diet or high-fat diet(HFD)for 18 weeks and their body weight changes were monitored.ELISA was used to measure serum total cholesterol(TC), triacylglycerol(TG), high-density lipoprotein(HDL-C)and low-density lipoprotein(LDL-C)levels.The extent of aortic lipid deposition in mice was assessed by oil red O staining.Results:During the feeding of a high-fat diet, CFIm25f/+ TaglnCre mice showed a significant increase in body weight compared to the control group[Male(1.01±0.06)g and(0.87±0.31)g, t=7.53, P<0.05; Female: (0.64±0.02)g and(0.35±0.04)g, t=9.68, P<0.05].After 18 weeks of high-fat diet feeding, CFIm25f/+ TaglnCre mice had significantly higher levels of TC[(6.80±0.35)mmol/L and(3.76±0.87)mmol/L, t=5.63, P=0.004], TG[(0.97±0.21)mmol/L and(0.42±0.10)mmol/L, t=4.08, P=0.015], and LDL-C[(5.20±0.30)mmol/L and(2.00±0.98)mmol/L, t=5.40, P=0.006]compared to the TaglnCre group.Specifically, TC levels increased by 80.72%, TG increased by 132.79%, and LDL-C increased by 160.32%.There was a significant increase in aorta lipid deposition and atherosclerotic plaque area in CFIm25f/+ TaglnCre mice( P<0.05). Conclusions:The research indicated that VSMCs-specific CFIm25 knockdown in mice further worsened hyperlipidemia and atherosclerotic lesions.

In recent years, due to changes in the epidemiology of colorectal cancer in the United States, the update of evidence-based medical evidence for screening, and the emergence of various new screening methods, various organizations in the United States, such as American College of Gastroenterology、Preventive Services Task Force, have updated guidelines for colorectal cancer screening in average-risk individuals. These guidelines have different recommendation levels in terms of starting and ending age, screening methods and frequency for colorectal cancer screening. A comprehensive understanding of the key points of these guideline updates and the similarities and differences recommended by different guidelines has important reference value for the colorectal cancer screening in China.
