Objective To investigate the safety and efficacy of endoscopic tissue adhesive injection combined with sequential endoscopic variceal ligation for gastroesophageal varices of Le,g type. Methods Twenty-three patients with gastroesophageal varices of Le,g type were enrolled to General Hospital of PLA from May 2013 to March 2015, who were treated with endoscopic tissue adhesive injection in the fundic and cardiac site in the first session, followed with endoscopic variceal ligation for esophageal varices. The clinical data, procedure complications and efficacy were retrospectively analysed. Results All procedures were successfully performed with no such evident complications as intraoperative and postoperative bleeding, embolization, mediastinal infection or death with an average hospitalization time of 15. 3±4. 09 days. Mild and moderate thoracalgia occurred in 13 patients(56. 5%), low-grade fever in 2 patients(8. 7%, recovered after symptomatic treatment for 1-2 days) . During the follow-up of 2 weeks, the rate of varices disappearance was 56. 5% (13/23) and no recurrent bleeding was observed. Six months after discharge, 10 patients underwent endoscopy again, varices disappeared in 4 and 6 with remains;the 13 others showed no hemorrhage according to follow-up call. Conclusion The therapy of endoscopic tissue adhesive injection with sequential endoscopic variceal ligation for gastroesophageal varices of Le,g type is safe and efficient.

Objective To evaluate the clinical effect of balloon closure combined with endoscopic therapy on spontaneous gastrorenal shunt ( SGRS ) and spontaneous splenorenal shunt ( SSRS ) . Methods The data of 33 patients of gastric varices with SGRS or SSRS diagnosed in the Chinese PLA General Hospital between January 2009 and February 2016 were collected. All patients were treated with the balloon retrograde distributary channel blocking technique and endoscopic histoacryl injection. Patients' clinical data, complications and effect of endoscopic therapy were retrospectively analyzed. Results In the 33 patients of gastric varices, gastrorenal shunt was found in 28 ( 84. 8%) cases and splenorenal shunt was found in 5 ( 15. 2%) cases. After the balloon blocking technique, 24 cases ( 72. 7%) were occluded successfully. Four cases failed in occlusion of SSRS due to tortuosity. There were no postoperative ectopic embolism, infection, hepatic encephalopathy, liver function deterioration, and other complication. Early latex varices were found in 21 cases after three months follow-up. Conclusion The balloon blocking technique combined with tissue adhesive injection could safely and effectively avoid the risk of ectopic embolism and plays an important role in the treatment of gastric varices in merger portasystemic shunt.

Objective:Differential expression of serum exosomal miRNAs were detected for NAFLD patients and healthy controls, thereby determining the role of serum exosomal miRNAs in the pathogenesis, diagnosis, and treatment of NAFLD.Methods:Four patients with S2-3 NAFLD who shared similar demographic features and personal histories, and matched healthy controls were recruited for high-throughput sequencing of serum exosomal miRNAs. Four miRNAs with the most significant differential expression were verified by qRT-PCR in three groups (S1, S2-3, and control groups) with 20 cases in each group. Target gene prediction was performed for these differentially-expressed miRNAs, along with GO and KEGG enrichment analyses for the target genes. T-test or ANOVA were used for normally distributed data. Wilcoxon rank sum test was used for ranked data and non-normally distributed data. The count data used Pearson chi-square test or Fisher's exact test.Results:There were 19 serum exosomal miRNAs with significantly different levels of expression ( P < 0.05) and a fold-change > 2. The expression of hsa-miR-122-5p, hsa-miR-146b-5p, and hsa-miR-197-3P was highest in the S2-3 group, followed by the S1 and control groups (in order); hsa-miR-483-3p expression was higher in the NAFLD group (S1 or S2-3) than the control group. There were 84 pathways significantly enriched in target genes. From 20 pathways closely related to NAFLD, at least 5 target genes which were simultaneously correlated to all 10 pathways were screened (PIK3R2, AKT2, AKT3, MAPK1, and NFKB1). Conclusion:Differential expression of serum exosomal miRNAs was detected in NAFLD patients and healthy controls. Four miRNAs with the greatest fold-changes were assessed to judge the severity of fatty degeneration of the liver. The research findings provide reference for non-invasive identification of new biomarkers and specific targets for NAFLD treatment.
