Objective To evaluate the therapeutic effect of different types of biliary tract reconstruction on the post- resection of congenital choledochal cyst (CCC). Methods 106 cases of CCC undergoing resection of CCC with Roux-en-Y hepaticojejunostomy as biliary tract reconstruction were followed up and analysed. Results In this series, three kinds of biliary tract reconstruction were performed, including single Roux-en-Y hepaticojejunostomy in 48 cases, intussusceptive valve and rectangular valve lying on the jejunal segmental of Roux-en-Y hepaticojejunostomy in 37 and 21 cases, respectively. 61 cases were followed up for 4.82 years in average. None of them occurred anastomasis stricture. There were 4 cases with ascending cholangitis after primary operation: of them 3 after single Roux-en-Y hepaticojejunostomy; symptoms of 2 out of the 3 cases disappeared after reoperation to set up an intussusceptive valve plasty on the jejunal segmental of Roux-en-Y hepaticojejunostomy; another one was in rectangular valve group. Occasional abdominal pain tooke place in 8 patients, of them, 5 in single Roux-en-Y hepaticojejunostomy group, 2 and 1 in intussusceptive valve and rectangular valve groups, respectively. No patients suffered from ascending cholangitis in the intussusceptive valve plasty group. Conclusions The postoperative ascending cholangitis and anastomasis stricture can be prevented effectively, if a prophylactic intussusceptive valve on the jejunal segmental of Roux-en-Y hepaticojejunostomy is carried out after resection of CCC for biliary tract reconstruction. This procedure corresponds to the biliary tract physiology.

BACKGROUND:Resveratrol is a natural antioxidant extracted from plants.Its mechanism of improving exercise-induced fatigue mainly focuses on the protective effect against oxidative stress and inflammation.In this study,the protective mechanism of resveratrol on exercise-induced fatigue was mainly discussed from the perspective of gluconeogenesis. OBJECTIVE:To investigate the effect of resveratrol on gluconeogenesis in exercise-induced fatigue rats. METHODS:After 1 week of adaptive training,male Sprague-Dawley rats were randomly divided into 4 groups with 12 rats in each group:blank control group,resveratrol group,exercise group,resveratrol + exercise group.Weight-bearing swimming training was used to simulate long-term medium-high intensity exercise.After swimming with a weight of 5%for 1 hour every day,50 mg/kg resveratrol solution or the same volume of dimethyl sulfoxide solvent were given orally,6 days a week,for a total of 6 weeks.Samples were collected 24 hours after the last exercise,and the levels of urea nitrogen,creatine kinase,blood glucose,liver glycogen and lactic acid and pyruvate in liver tissue were detected by the kit.The activity of phosphoenolpyruvate carboxykinase was detected by microassay,and the activity of glucose-6-phosphatase was detected by enzyme-linked immunosorbent assay.Real-time fluorescence quantitative PCR was used to detect the gene expression of silent information regulator 1,cAMP-response element binding protein and peroxisome proliferator-activated receptor-γ coactivator-1α. RESULTS AND CONCLUSION:In the exercise group,plasma urea nitrogen and creatine kinase levels of rats were significantly increased(both P<0.05),liver lactate and pyruvate levels and lactate/pyruvate ratio were significantly increased(all P<0.01),and blood glucose and liver glycogen contents were significantly decreased(both P<0.01).Resveratrol supplementation could effectively improve the above conditions.Exercise significantly decreased the activities of phosphoenolpyruvate carboxykinase and glucose-6-phosphatase(P<0.01,P<0.05),and resveratrol supplementation significantly increased the activity of phosphoenolpyruvate carboxykinase in liver tissue(P<0.01).The mRNA expression levels of silent information regulator 1,cAMP-response element binding protein and peroxisome proliferator-activated receptor-γ coactivator-1α in liver tissue of the exercise group were significantly decreased(all P<0.01),while resveratrol supplementation could significantly increase the gene expression levels of this pathway.To conclude,resveratrol can relieve exercise-induced fatigue caused by long-term medium-high intensity exercise,and its mechanism may be related to up-regulating the gluconeogenesis regulatory pathway,improving rate-limiting enzyme activity,promoting liver gluconeogenesis,and increasing blood glucose and liver glycogen levels.

BACKGROUND:Studies have shown that resveratrol can relieve exercise-induced fatigue and protect the heart,but its action mechanism needs further study. OBJECTIVE:To explore the protective effect and regulatory mechanism of resveratrol on ventricular remodeling in exercise-induced fatigue rats. METHODS:Totally 48 male Sprague-Dawley rats were randomly divided into four groups,with 12 rats in each group.Rats in the blank control group were fed conventionally.After one week of adaptive training,rats in the exercise-related fatigue group and exercise-related fatigue with resveratrol supplement group were trained by 6-week weight-bearing swimming(5%body mass lead block fixed in the tail,70%-80%maximal oxygen uptake intensity),6 days a week,60 minutes a day.Rats in the resveratrol supplement group and exercise-related fatigue with resveratrol supplement group were given resveratrol(50 mg/kg per day)by gavage one hour after exercise intervention.Blank control group and exercise-related fatigue group were given the same volume of 2%dimethyl sulfoxide,6 days a week,once a day for 6 weeks.The body mass and heart mass of the rats were measured 24 hours after the last intervention.Plasma creatine kinase isoenzyme,cardiac troponin 1,pyruvate dehydrogenase and uncoupling protein 1 levels in myocardial tissue were determined by ELISA.The mRNA expression levels of ventricular remodeling-related factor Foxp1,transforming growth factor β1 and endothelin 1 were detected by RT-PCR. RESULTS AND CONCLUSION:Compared with the blank control group,the body mass of rats decreased and the heart mass increased in the exercise-related fatigue group(P<0.05).Compared with the exercise-related fatigue group,the body mass and heart mass of the rats reduced in the exercise-related fatigue with resveratrol supplement group(P<0.05).Compared with the blank control group,the levels of creatine kinase isoenzyme,cardiac troponin 1 and uncoupling protein 1 increased(P<0.01),and the level of pyruvate dehydrogenase decreased(P<0.01)in the exercise-related fatigue group.Compared with the exercise-related fatigue group,the levels of creatine kinase isoenzyme,myocardial troponin 1 and uncoupling protein 1 decreased(P<0.05),and the level of pyruvate dehydrogenase increased(P<0.05)in the exercise-related fatigue with resveratrol supplement group.Compared with the blank control group,the expression of the Foxp1 gene decreased(P<0.01),and the expression of transforming growth factor β1 and endothelin 1 gene increased(P<0.01)in the myocardium of the exercise-related fatigue group.Compared with the exercise-related fatigue group,the expression of the Foxp1 gene in the myocardium of the exercise-related fatigue with resveratrol supplement group increased(P<0.01),while the expression of the transforming growth factor β1 and endothelin 1 gene decreased(P<0.05).It is suggested that exercise-induced fatigue can promote myocardial adaptability and cause compensatory hypertrophy.Resveratrol can improve myocardial injury and energy metabolism and delay ventricular energy remodeling in rats.This effect may be related to the regulation of Foxp1/transforming growth factor β1/endothelin 1 signaling pathway.

Objective:
To investigate the clinical efficacy of dorsal mosaic surgery with penis free flap for the treatment of anterior urethral stricture after TURP.
Methods:
We analyzed the clinical data of the patients with anterior urethral stricture after TURP from January 2010 to December 2017 in Yan′an hospital affiliated to Kunming medical university retrospectively. The patients' age ranged from 58 to 75 years, with an average of 64.3 years. The time from TURP to the diagnosis of anterior urethral stricture was 1-12 month, with an average of 3.5 months. 5 cases were urethral stricture at penis segment, 11 cases were urethral stricture at the junction of penis and scrotum, and the length of the narrow urethra was 2-5 cm, with an average of 3.4cm. The average maximum uroflowmetry in preoperative was (5.3±2.7) ml/s.11 cases were treated with regular urethral dilatation and the treatment durable time was more than 6 months, 5 cases were treated with intraurethral incision combined with urethral dilatation(1 or 2 times). 16 cases were not effective after receiving the above treatment, so that all cases were treated with dorsal mosaic surgery with penis free flap. Subarachnoid anesthesia combined with epidural anesthesia, the patient took the supine position.The distal end of urethral stricture was defined by urethral dilator. Incision from the ventral side of the urethra. The length of the incision was extended 0.5 cm based on the length of urethral stricture in urethral angiography.Anatomize the left and right sides of the urethral stricture and longitudinally incision the ventral side of the urethral cavernous body. The length of the incision was extended 0.5 cm to the normal urethral mucosa. The traction line retracts the ventral urethral edge along both sides.The corresponding medial line of the dorsal urethra was incised to the tunica albuginea, and the urethral edge of the dorsal side was separated from the tunica albuginea to form an elliptical region on the tunica albuginea.According to the size of the ellipse, the full thickness of the penis flap was taken, and the size of the flap was beyond the edge of the elliptical area about 0.3 cm.The free flap was covered with the 6-0 absorbable suture on the elliptical area (the skin surface was on the inner side of the urethra), the edge of the free flap was intermittently sutured with the urethral edge of the dorsal side, Multi-needle intermittent sutured flap surface on the corpus cavernosum bed.Using a silicone catheter as the stent tube of the new urethra, the 6-0 absorbable suture closes the ventral side of the incisional urethral sponge.The multi-layered meat film was sutured to prevent leakage of urine, and the fascia and skin were sutured layer by layer. The 5-0 absorbable thread sutures the wound after the foreskin was taken.
Results:
The operations were successfully completed. The operation time was 90-120 min, with an average of 102.3 min. The intraoperative blood loss was 10-30 ml. The symptoms of dysuria were relieved in all patients after removal of the catheter at 3 weeks postoperative. 4 weeks after surgery, no signs of urethral stricture were observed in urethrography. And the maximum flow rate was >15 ml/s in 13 cases, while 3 cases was 10-15 ml/s. The mean maximum flow rate in postoperative was [(20.4±7.3) ml/s], which was significantly higher than that in preoperative (

Objective:To investigate the improved performance of hepatic elastography combined with the serum biomarkers for the diagnosis of biliary atresia.Methods:A total of 193 patients with suspected biliary atresia in Beijing Children′s Hospital from March 2019 to November 2020 were consecutively collected. All patients were randomly divided into the training cohort and validation cohort at a ratio of 7∶3. LASSO regression analysis was used for the selection of the model index based on the data set from the training cohort including the serum biomarkers, demographic features (age and sex) and hepatic elastic measurement, and a diagnostic model for biliary atresia was subsequently developed by weighting on the basis of the dominance ration. The performance of the model was respectively evaluated with respect to the discrimination and calibration in each cohort.Results:Alanine aminotransferase (ALT), glutamyl transferase (GGT) and hepatic elastic measurement were selected to build the model. The area under the ROC curve of the final diagnostic model was 0.943 with a sensitivity of 90.9% and a specificity of 85.7% in the training cohort, and 0.955 in the validation cohort. Hosmer-Lemeshow test ( P=0.292, P=0.951) and calibration curves further validated its satisfactory calibration in both cohorts. As demonstrated by Delong et al.test, employing the model in the training cohort achieved the best diagnostic performance compared with using single model index ( P<0.001, P=0.016, P<0.001). In the validation cohort, the decision curve analysis showed the model had a higher overall net benefit over using hepatic elastography alone in every predicted probability. Conclusions:The diagnostic model for biliary atresia, which incorporates ALT, GGT and hepatic elastic measurement, can improve the performance of hepatic elastography with a higher clinical value.
