ABSTRACT

Objective:To investigate the clinical value of totally laparoscopic exclusion of splenic artery aneurysm combined with pericardial devascularization for portal hypertension com-plicated with splenic aneurysm.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 17 patients with portal hypertension complicated with splenic aneurysm who were admitted to 2 medical centers (15 cases in Shenzhen University General Hospital and 2 cases in Wuhan First Hospital) from January 2013 to May 2020 were collected. There were 7 males and 10 females, aged (59±14)years. All patients underwent totally laparoscopic exoclusion of splenic artery aneurysm combined with pericardial devascularization. Observation indicators : (1) surgical and postoperative conditions; (2) complications; (3) follow-up. Follow-up was conducted by out-patient examiantion and telephone interview to detect the effect of exclusion of arterial tumor, and blood re-flow, portal vein thrombosis and survival of patients 3 months after operation. The follow-up was up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Results:(1) Surgical and postoperative conditions. All 17 patients successfully completed the operation, without perioperative death. The operation time, volume of intraoperative blood loss of 17 patients were (181±30)minutes, 187(range, 90?420)mL. The white blood cell count, red blood cell count, hemoglobin, serum albumin were (9±4)×10 9/L, (3.5±0.9)×10 12/L, (86±17)g/L, (36±7)g/L on the postoperative day 3. Time to postoperative abdominal drainage tube removal and duration of post-operative hospital stay were (7±4)days and (11±4)days. (2) Complications. All 17 patients had ascites after surgery, which were improved after oral treatment with diuretics. There was no complication such as intra-abdominal hemorrhage, gastrointestinal fistula, pleural effusion, infection, abscess formation, fever and vascular embolism. (3) Follow-up. All the 17 patients were followed up for 28.6(range, 7.0?84.0)months. During the follow-up, the splenic aneurysm cavity of all patients was completely isolated, no blood re-flow and no portal vein thrombosis was observed, and no patient died. Conclusion:Totally laparoscopic exclusion of splenic artery aneurysm combined with pericardial devascularization is safe and feasible in the treatment of portal hypertension complicated with splenic aneurysm.

ABSTRACT

Objective To investigate the expression of microRNA (miRNA) in placenta tissue, explore the function of miRNA in pathogenesis of gestational diabetes mellitus (GDM). Methods Placenta tissue from pregnant women with GDM and normal controls were selected from January 2013 to January 2014. Expression of miRNAs were detected by sequencing technique and quantity real time PCR(qRT-PCR). Target genes of miRNA were analyzed by KEGG. Results 52 insulin signaling pathway related miRNAs including 47 up-regulated and 5 down-regulated were differentially expressed in GDM compared with normal control. Expression of placental hsa-miR-548am-5p and hsa-miR-95-5p were significantly increased , but hsa-miR-1246 was significantly lower (P <0.05) in GDM group than normal control; all the results were consistent with sequencing results. Key points of insulin signaling pathway could regulate expression of targets such as PI3K. Conclusion miRNA expression in GDM placenta was abnormal.A variety of exp ressions of miRNAs were involved in the pathogenesis of GDM by regulating insulin signaling pathway.

ABSTRACT

<p><b>AIM</b>To evaluate the effect of paeonol on the activity of tyrosinase and provide experimental evidence for the treatment of hyperpigmentation disorders.</p><p><b>METHODS</b>Tyrosinase activity was estimated by measuring the oxidation rate of L-3,4-dihydroxyphenylalanine (L-Dopa). The inhibitory effects of paeonol on the activity of mushroom tyrosinase and Michaelis-Menten kinetics were deduced from the Lineweaver-Burk plots.</p><p><b>RESULTS</b>The inhibitory concentration of paeonol leading to 50% enzyme activity lost (IC50) was estimated to be 0.60 mmol x L(-1). The inhibition constants for paeonol binding free enzyme, K(I), and substrate-enzyme, K(IS), are 0.084 and 0.12 mmol x L(-1), respectively.</p><p><b>CONCLUSION</b>Paeonol is a potential mixed inhibitor of mushroom tyrosinase. The mixed inhibition function may originate from its ability to form a Schiff base with a primary amino group and to chelate copper at the active site of tyrosinase.</p>

ABSTRACT

Objective To investigate the feasibility of laparoscopic repair for ingunal hernia after peritoneal dialysis. Methods Laparoscopic repair of inguinal hernia was conducted in 26 patients with chronic renal insufficiency who had received peritoneal dialysis for a long time. For indirect inguinal hernia, a piece of mesh was placed in the abdominal cavity and the internal ring was sutured and ligated under laparoscope. For direct inguinal hernia, the hernia sac was high suspended and then the mesh onlay was placed under laparoscope. Results The laparoscopy was successfully performed in all the 26 patients, without conversions to open surgery. No postoperative hematoma of scrotum or refractory neuralgia was observed. Follow-up examinations for 6~12 months (mean, 9 months) showed no recurrence. Conclusions Laparoscopic herniorrhaphy for inguinal hernia after peritoneal dialysis is feasible, effective, and safe.

ABSTRACT

Objective To investigate the causes of intractable abdominalgia after simple choleystectomy and analyse the therapeutic effect of endoscopic sphincterotomy (EST).Methods 84 patients undergoing EST were retrospectively viewed from 1987 to 1998. Results Sixty five out of 84 patients were followed up, in which the clinical signs disappeared completely in 51 cases (78%), and there were 6 cases with relapsing symptom(9%),3 cases with intermittent relapsing symptom (4%). Therapy was ineffective in 5 cases. The intractable abdominalgia is a specific sign of postcholecystectomy syndrome. EST is effective in removing the nervous structure in duodenal papilla submucosa and sphincter muscle layer responsible for abdominal pain, therefore eliminated or relived the pain.Conclusion EST has a significant effect on intractable abdominalgia after simple cholecystectomy in the majority of patients.
