Objective:To observe the serum level of fibroblast growth factor-23(FGF-23) in patients with end stage renal disease (ESRD) and study its association with phosphorus and vitamin D metabolism.Methods: Serum FGF-23 level was determined by enzyme-linked immunosorbent assay (ELISA) in ESRD patients undergoing haemodialysis (HD, n=50) and peritoneal dialysis (PD, n=24) and in twenty healthy controls (control group,n=20).Serum level of 1,25-(OH) 2VitD was measured by enzyme immunoassay(EIA).Serum intact parathyroid hormone (PTH), creatinine, and calcium and phosphorus were also measured.Results: Serum FGF-23 was obviously higher in HD group([88.51?35.01] ng/L vs [11.76?3.63] ng/L)and PD group([87.85?33.65] ng/L vs [11.76?3.63] ng/L)than in control group. Moreover, the serum level of 1,25-(OH)2VitD was lower in HD and PD groups than in control group ([19.82?4.99] pmol/L vs [48.37?3.47] pmol/L; [24.31?7.11] pmol/L vs [48.37?3.47] pmol/L ), and the level of 1,25-(OH)2VitD was much lower in HD group than in PD group. Pearson relativity analysis showed that serum FGF-23 level was positively correlated with serum creatinine, phosphorus, intact PTH and duration of dialysis(P

Objective:To investigate the changes of adrenomedullin(ADM) and adrenotensin(ADT) in hemodialysis patients. Methods:The plasma concentrations of ADM and ADT were measured by radioimmunoassay. Results:Plasma ADM was significantly higher in the hypertensive group(P

Objective To study the clinical value and the safety of endoscopic retrograde cholangio-pancreatography(ERCP)for chronic pancreatitis in the pediatric population.Methods Clinical data,endo-scopic reports,and radiography of chronic pancreatic patients aged from 2 to 17 years old who underwent ERCP between Jan.1,2008 and Apr.30,2014 at Endoscopy Center of Ruijin Hospital were reviewed.These patients were divided into 3 groups,patients aged from 2 to 6 years old as children group(n =27),patients aged from 7 to 12 years old as juvenile group(n =35)and patients aged from 13 to 17 as adolescent group(n =25). Their clinical data and complications were analyzed by groups.Results A total of 170 ERCP procedures were performed in 87 patients,with the success rate of 99.4%(169 /170).All patients were diagnosed as having chronic pancreatitis by ERCP.Success rates of children group,juvenile group and adolescent group were 97.6%(40 /41),100.0%(72 /72)and 100.0%(57 /57)respectively.There was no statistically significance among the three groups(P =0.207).No serious complications like bleeding or perforation occurred.No proce-dure-related mortality occurred in this study either.The rate of post-ERCP adverse events in children group, juvenile group and adolescent group were 41.5%(17 /41),25.0%(18 /72)and 24.6%(14/57),respective-ly.Children group had more adverse events than the juvenile group(P =0.039)and adolescent group(P =0.045).Conclusion Pediatric ERCP is highly effective in the pediatric population with chronic pancreatitis. The incidence of post ERCP adverse events is higher among the youngest children.

Objective To investigate the prognostic value of C5L2 in patients with hepatocellular carcinoma (HCC).Methods The data of 175 patients with HCC who underwent curative resection at Zhongshan Hospital,Fudan University from Oct.,2012 to Sep.,2013 were analyzed retrospectively.The correlation between C5L2 and clinicopathologic characteristics were explored.COX regression model was used to determine the influence of clinical parameters on predicting recurrence,and the prognostic value of combined application of C5L2 and AFP were evaluated by Kaplan-Meier method.In vitro,the expression of C5L2 were tested in 5 HCC cell lines,and Hep3B and Huh7 were chosen for down-regulation and up-regulation of C5L2,respectively,the abilities of invasion and migration were examined by transwell and the potential mechanism was explored.Results The C5L2 expression was correlated to gender,tumor size and recurrence,and the recurrence rate of low C5L2 expression group was higher.Also,the multivariate analysis showed that C5L2 low expression was an independent risk factor for recurrence.Moreover,the combined application of C5L2 and AFP could estimate prognosis more effectively.Knockdown of C5L2 in Hep3B promoted the invasiveness and motility,and increased the level of β-catenin and MMP2;conversely,overexpression of C5L2 in Huh7 inhibited the invasiveness and motility,and decreased the level of β catenin and MMP2.Conclusions C5L2 could be regarded as an auxiliary indicator for prognosis of HCC,thereby the evaluation of C5L2 could help with making effective and comprehensive management for HCC patients.

Objective To compare the clinical choosing principles of sedated colonoscopy with con-ventional colonoscopy. Methods Outpatients who were willing to accept colonoscopy with or without seda-tion were prospectively recruited,which were assigned to sedated colonoscopy group(n=362)and conven-tional colonoscopy group(n=323). All patients and endoscopists were asked to answer a self-administered questionnaire. The colonoscopy completion,operation time,procedure-related discomfort,and questionnaire results of the two groups were compared and statistically analyzed. Results The completion rate was 98. 9%in the sedated colonoscopy group(358/362)and 89. 8% in the conventional colonoscopy group(290/323) ( P=0. 337 ). The operation time of sedated and conventional group were( 5. 60 ± 3. 25 ) minutes and (7. 71 ± 5. 70)minutes respectively(P<0. 001). And the average cost was CNY 886. 54 per patient in se-dated group and CNY 386. 00 per patient in the conventional group. Patient satisfaction score of conventional group and sedated group were 4(3-4)and 3(2-3)points(P<0. 001),while endoscopist satisfaction score was 4(3-4)and 4(4-4)(P<0. 001). A total of 354 patients(97. 79%)in the sedated group and 225 pa-tients(69. 66%)in the conventional group showed willingness to repeat the identical colonoscopy( P <0. 001). Patients who were male(P=0. 035),having no past abdominal operations(P<0. 001),or no ab-dominal pain during colonoscopy( P =0. 015 )in the conventional group preferred to repeat conventional colonoscopy. Conclusion Although the examination time of conventional colonoscopy is longer than sedated colonoscopy,it could reduce anesthesia risk and the cost. Conventional colonoscopy remains an irreplaceable examination of colorectal diseases in developing countries. Physicians should not only focus on patients'com-fort during endoscopy,but also help patients make a decision based on their actual situation and endoscopic indications to make the best of medical resources.
