ABSTRACT
Hepatic fibrosis is a wound healing and scar repair reaction after liver injury, and is a common pathway for various chronic liver diseases. Activation and proliferation of hepatic stellate cells are the key links in the occurrence and development of hepatic fibrosis. Recent studies have shown that long non-coding RNAs are involved in regulating the activation, proliferation and apoptosis of hepatic stellate cells. Thus, probing its mechanism of action will provide a new strategy for the diagnosis, treatment and prognosis in liver fibrosis.
ABSTRACT
Objective To investigate the clinical characteristics and analyze the influencing factors of colorectal polyp recurrence after polypectomy.Methods The clinical data of colorectal polyps patients,who underwent colonoscopic polypectomy in our hospital and received a follow-up colonoscopy within 2 years [mean interval (18.8 ± 8.42) months] were collected between January 2012 and August 2015 (n =194).The polyps size,number,location,and pathology were detected.The polyps recurrence rate and influencing factors were analyzed.Results The polyps recurrence rate was 71.6％ (139/194) in 2 years.The patients,who aged ≥60 years,with adenoma number≥3,located in the left hemicolon and rectum,were easier to recurrence (P ＜ 0.05).Logistic regression analysis revealed that age and number of adenomas were independent factors of polyps recurrence whereas the sex,size,location,and pathology were not (P ＜ 0.05)during the surveillance interval.However,19.4％ nonneoplastic-polyp group and 15.5％ low-risk group turn into bad side.Conclusions The outcomes indicate that age and number of adenomas ≥3 were independent factors of polyps recurrence,whereas the size and pathological type were limited in risk stratification for patients after polypectomy.Two year may be the appropriate interval for endoscopic rescreening.
ABSTRACT
Objective To compare and discuss the clinical application effect of the end-to-end anastomosis of pancreatic and intestinal anastomosis,binding type of pancreatic and intestinal anastomosis,end-to side pancreatic duct anastomosis and modified pancreatic duct jejunum anastomosis.Methods Collected pancreatoduodenectomy in 95 cases,the end-to-end pancreatico duodenal sleeve type anastomosis in 23 cases,binding type pancreatic enteric anastomosis in 18 cases,end to side pancreaticojejunostomy anastomosis in 28 cases,improvement of the pancreatic duct jejunum end to side anastomosis in 26 cases,compared with four groups of patients with pancreatic enteric anastomosis time and postoperative complications.Results Anastomosis time:A group (34.0 ± 4.6) min,B group (31.0±5.8) min,C group (32.0 ±6.3) min,D group (14.0 ±4.2) min(P=0.037,P＜0.05).And the incidence rate of postoperative pancreatic fistula,bile leakage,abdominal cavity or digestive tract bleeding had no significant difference (P ＞ 0.05).Improvement of the pancreatic tube jejunum end to side coincident with a low incidence of pancreatic fistula,but different pancreatic enteric anastomosis way pancreatic fistula rate difference was not statistically significant,improvement of the pancreatic duct and jejunum mucosa end side group pancreatic enteric anastomosis anastomosis time significantly shorter in the three groups,the difference was statistically significant (P ＜ 0.05).Conclusion Improvement of pancreatic duct jejunum end to side anastomosis with short operation time,low incidence of pancreatic fistula,and the operation is simple and practical,safe.
ABSTRACT
Objective To evaluate the therapeutic effect and application value of laparoscopy combined with holmium laser in the treatment of intrahepatic and extrahepatic bile duct stones.Methods Retrospectively analyzed the clinical data of 22 cases with intrahepatic and extrahepatic bile duct stones who treated with laparoscopy choledo-choscopy combined with holmium laser lithotripsy(the observation group),and 21 cases who treated with laparoscopy combined with choledochoscopic lithotomy(the control group).The clinical curative effect was compared between the two groups.Results In the observation group,the residual stones completely removed in 21 cases(95.4%),the mean operation time was (130 ±13)min,the intraoperative bleeding volume was (85 ±20)mL,the average hospitali-zation time was (8.3 ±2.0)days,without conversion to open surgery,no incision infection,1 case had residual stones after operation,through T tube sinus tract choledochoscopy took a stone again.In the control group,took net calculi in 13 cases(61.9%),the average operation time was (135 ±20)min,the intraoperative hemorrhage volume was (70 ± 15)mL,the average hospitalization time was (14.5 ±2)days,6 cases converted to laparotomy,incision infection in 2 cases,8 cases had residual stones after operation,through T tube sinus combined with choledochoscopy again take stone,which 2 secondary mirror lithotomy in 6 cases,3 cases of 2 stones.The differences of the two groups in stone from the net rate,conversion rate,average hospitalization time were statistically significant(χ2 =2.203,2.897,t =4.293,P =0.033,0.006,0.017).The differences of mean operation time,intraoperative hemorrhage had were not statistically significant(t =1.176,1.629,P =0.246,0.111).Conclusion It is safe,effective and minimally invasive for the treatment of intrahepatic and extrahepatic bile duct stones with holmium laser combined with endoscopic holmi-um laser.
ABSTRACT
Objective To explore the differences in clinical features between the latent autoimmune diabetes in adults (LADA) and type 2 diabetes mellitus (T2DM) in the elderly.Methods Clinical features of 41 cases with LADA and 49 cases with T2DM were retrospectively analyzed and compared.Results (1) Body mass index (BMI),fasting and postprandial levels of cpeptide,triglyceride (TG) and serum albumin were lower in LADA patients than in T2DM patients.(2) The levels of fasting and postprandial blood glucose were higher in LADA patients than in T2DM patients.(3) There were no statistically significant differences in the disease course,blood pressure (BP),and the functions of liver and kidney between LADA and T2DM patients.Conclusions As compared with T2DM patients,LADA patients have higher blood glucose level,lower BMI and TG level,and poorer function of islet B cell.But there is no significant difference in the chronic complications between two groups.
ABSTRACT
Objective To evaluate the application of dynamic magnetic resonance imaging in the diagnosis of female stress urinary incontinence(SUI). Methods Dynamic magnetic resonance imaging(DMRI)were performed on 30 healthy female volunteers and 35 female SUI patients.DMRI of the pelvic floor at rest and OR maximal strain were performed by using sagittal T2-weighted fast gradient sequences.The distance of Urethra-vesical junction to the pubococcygeal line,the posterior vesicourethral angle and angle of inclination of the urethral axis were measured at rest and on maximal strain position.The t-value exact test were used to analyze the data. Results At rest the Urethravesical junction laid above pubococcygeal line on both control and SUI groups.Mean distance from the Urethra-vesical junction to pubococcygeal line at rest had no difference between the two groups.On straining,the mean Urethra-vesical junction descent distance in the SUI group(-0.9±1.1cm)was significantly higher than in control group(-0.14±0.3 cm),(P＜0.001).On straining,the mean angle of urethral inclination in the SUI group(65±37°)was significantly bigger than in control groups (17±21°),(P＜0.05).The posterior vesicourethral angle in the SUI groups(156±36°)was significantly bigger than in control groups(113±28°),(P＜0.05). Conclusion Dynamic magnetic resonance imaging is a non-invasive.easily applied method in the diagnosis of SUI.
ABSTRACT
Objective To explore the diagnosis and surgical treatment of primary intestinal tumors, and improve the level of treatment. Methods Retrospective analysis of the clinical was made on the 68 cases of primary small intestinal tumors confirmed by pathological examination in our department in recent 20 years. HZ Results 34.8%(21/68) was benign tumors in 68 cases, and 69.1%(47/68) was malignancies. The common clinical prevsentations were abdominal pain (69.1%,47/68). gastrointestinal he morrhage (41.1%,28/68) and abdomen mass (13.2%,9/68). The preoperative misdiagnosis rate was 70.5%(48/68) .All the 68 cases performed operation, and no death. The 1 ,2 and 5 years survival rates of malignant tumors were 65.8%,42.1% and 29.3% respectively. Conclusions The clinical presertation of primary small intestinal tumor is non-spectific and the misdiagnosis rate is high. Kinds of diagnosis examinations should be done for the cases whose diagnosis are uncertain, and laboratory examinations should be considered if it is need. The main choice of treatment is surgery and the chemotherapy is necessary for malignant tumors also.
