Diabetic nephropathy (DN) is a common kidney disease in diabetic patients. Long non-coding RNA maternally expressed gene 3 (MEG3) and microRNA (miR)-23c are reported to be implicated in DN development. Nevertheless, it is unclear that the molecular mechanism between MEG3 and miR-23c in DN remains unclear. Methods: Human mesangial cells (HMCs) were treated with high glucose (HG) to simulate the DN status in vitro. Expression of MEG3 and miR-23c was measured. Effects of MEG3 silencing on HG-stimulated HMC injury were determined. The relationship between MEG3 and miR-23c was verified by the dual-luciferase reporter and RNA immunoprecipitation assays. Results: MEG3 was overexpressed in serums from DN patients and HG-stimulated HMCs. MEG3 knockdown weakened HG-stimulated HMC proliferation, extracellular matrix (ECM) accumulation, and inflammation. MEG3 regulated lin-28 homolog B (LIN28B) expression through adsorbing miR-23c. MiR-23c inhibitor reversed MEG3 knockdown-mediated effects on HG-stimulated HMC proliferation, ECM accumulation, and inflammation. LIN28B overexpression overturned miR-23c mimic-mediated effects on HG-stimulated HMC proliferation, ECM accumulation, and inflammation. Conclusion: MEG3 regulated HMC injury via regulation of the miR-23c/LIN28B axis in DN, which can help us better understand the mechanism of DN mediated by MEG3.

Objective:To study the safety and efficacy of using entrapped duct-to-mucosa pancreaticojejunostomy for patients with small pancreatic ducts of less than 3 mm in diameter.Methods:The clinical data of patients who underwent entrapped duct-to-mucosa pancreaticojejunostomy at Henan Province People's Hospital from January 2017 to December 2019 were retrospectively analyzed. The incidences of complication including pancreatic fistula and abdominal hemorrhage were studied. The duration to carry out the pancreaticojejunostomy and postoperative hospital study were also analyzed.Results:Of 98 patients included in this study, there were 58 males and 40 females, with an average age of 62.3 (aged 24 to 73) years. The average time of completing the pancreaticoenterostomy was (10.2±3.1) min. There were 10 patients (10.2%) who developed grade A pancreatic fistulae. There were no grade B or C pancreatic fistulae, no portoperative bleeding and no perioperative deaths. The postoperative hospital stay was (13.4±4.6) days.Conclusion:Entrapped duct-to-mucosa pancreaticojejunostomy was simple, quick, safe and effective in patients with small pancreatic ducts.

Objective:To summarize our experience in diagnosis and treatment of Budd-Chiari syndrome(BCS) accompanied with hepatic nodules.Methods:The clinical data of 33 patients with BCS accompanied with hepatic nodules who were treated at Henan Provincial People's Hospital from January 2012 to December 2018 were retrospectively analysed. A total of 33 patients were enrolled, including 17 males and 16 females, with an average age of 51 years. Analyze the treatment and prognosis of different types of nodules.Results:Of 33 patients, 27 were diagnosed to have hepatocellular carcinoma and 6 benign proliferative nodules. Treatment of patients with hepatocellular carcinoma included, transcatheter arterial chemoembolization ( n=1) and hepatectomy ( n=26). The survival time of these patients with hepatocellular carcinoma ranged from 10.0 to 78.0 months (mean 37.8 months). For the remaining 6 patients with benign nodules, the nodules were multiple and no malignant changes were observed on follow-up. Conclusion:For patients with BCS associated with benign nodules, no specific treatment was required. Hepatocellular carcinoma assocated with BCS had good prognosis. An aggressive surgical resectional approach is recommended to treat and to relieve the hepatic outflow obstruction.

Objective To analyze the effects of structured fat emulsion and medium/long chain fat emulsion on blood lipids,immune cells and acute inflammation after hepatectomy for hepatocellular carcinoma.Methods Total of 60 patients with hepatocellular carcinoma who underwent hepatectomy in Henan People's Hospital (Zhengzhou University People's Hospital) from January 2013 to March 2017 were divided into experimental group (using structured fat emulsion) and control group (using medium/long chain fat emulsion),30 cases in each group.Triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),total cholesterol (TC),T lymphocyte level,fibrinogen (FIB),C-reactive protein (CRP),prostaglandin E2 (PGE2) were detected before and 2,4,6 and 8 days after infusion.Results There were no significant differences in LDL-C,HDL-C,TG and TC between the two groups before infusion (P＞0.05).On the 2nd day of parenteral nutrition infusion,the level of blood lipids in both groups was higher than experimental group before infusion;on the 4th,6th and 8th day of infusion,LDL-C,HDL-C,TG and TC in the control group were higher than those in the experimental group (P＜0.05).After parenteral nutrition infusion,the levels of CD3+,CD4+,CD8+,CD4+/CD8+ in both groups were higher than experimental group before infusion,and the experimental group was higher than the control group,the differences were statistically significant (P＜0.05).Compared with before infusion,level of FIB,CRP and PGE2 began to increase on the 2nd day of infusion,and the differences were statistically significant (P＜0.05).On the 2nd,4th,6th and 8th day,CRP in the control group was higher than experimental group.And resepeatively (19.12±5.84) mg/ml vs.(13.76±2.36) mg/ml,(31.67±8.68) mg/ml vs.(17.21±2.66) mg/ml,(22.15±8.33) mg/ml vs.(12.48±0.63) mg/ml,(9.65±4.66) mg/ml vs.(7.52±0.99) mg/ml,and PGE2 were also higher than that in the experimental group (P＜0.05).Conclusion Structured fat emulsion is superior to medium/long chain fat emulsion in improving blood lipid,immune cells and inflammatory reaction in patients after hepatectomy.

Objective To study the combined use of ALPPS (associating liver partition and portal vein ligation for staged hepatectomy) with hepatic artery reconstruction in the treatment of hilar cholangiocarcinoma with hepatic arterial involvement.Methods The clinical data of 7 patients with hilar cholangiocarcinoma who underwent ALPPS combined with hepatic arterial resection and reconstruction were analyzed retrospectively.The technical points and the perioperative management were analyzed.Methods At the first stage,the relationship between the tumor and the vessels were explored,the portal vein of the part of the liver to be resected was ligated and the liver was transected with a CUSA (Cavitron Ultrasound Surgical Aspirator).Then the bile duct was cut and a hepaticojejunostomy was completed.Finally,under ultrasound guidance,a bile duct drainage tube was inserted transhepatically into the part of the liver which was to be resected.Two to three weeks later,and after enough hypertrophy of the liver remnant size was confirmed,tumor resection was completed with reconstruction of the hepatic artery.Results Seven patients underwent the second stage operation,with no perioperative death.Six patients developed pulmonary infection and were treated successfully with conservative treatment.Two patients developed postoperative bile leak with secondary abdominal infection.One patient developed postoperative hepatic artery thrombosis secondary to biliary tract infection.Conclusion ALPPS combined with hepatic artery reconstruction was safe and feasible in the treatment of hilar cholangiocarcinoma with hepatic arterial involvement.
