Background:The incidence of inflammatory bowel disease( IBD ) is increasing in recent years,however,its pathogenic mechanism has not been fully clarified. Previous studies revealed that adipokines played crucial roles in regulating intestinal inflammation. Aims:To investigate the role of visfatin,an adipocytokine,and its clinical significance in active IBD. Methods:Ninety-one patients with active IBD including 61 Crohn’s disease( CD)and 30 ulcerative colitis ( UC)at the First Affiliated Hospital of Soochow University and Suzhou Municipal Hospital from May 2015 to Dec. 2015 were enrolled in this study,and 48 healthy subjects were served as controls. Serum level of visfatin was determined by ELISA. Correlation of serum visfatin level with clinical features of IBD was analyzed,its diagnostic performance for IBD was assessed by ROC curve. Results:Serum level of visfatin was significantly higher in patients with active CD and UC than in healthy controls[(385. 24 ± 112. 64)pg/mL and(378. 91 ± 118. 57)pg/mL vs. (321. 11 ± 96. 27)pg/mL, P all ﹤0. 05]. Significant positive correlation was found between serum visfatin level and disease activity index(Mayo score)of UC( r =0. 398,P ﹤0. 05 ),however,no correlations were found between serum visfatin level and disease activity index of CD,CRP and ESR,two common inflammatory indicators for IBD and location of IBD(P all ﹥0. 05). The area under curve( AUC)of serum visfatin for diagnosis of CD and UC were 0. 654 and 0. 622,respectively;the diagnostic accuracy was relatively low. Conclusions:Serum visfatin might be associated with the active intestinal inflammation in IBD and has the potential to be served as a clinical index for active UC.

Objective To investigate the adjustment methods and evaluation for children after cochlear implantation. Methods 6 children after artificial cochlear implantation were debugged by subjective psychological physical test, objective methods such as electricity induced composite action potential (ECAP), electrically evoked stapedius reflex threshold (ESRT) and electrically evoked auditory brainstem response (EABR). Results All the children got satisfied data. Conclusion For the children after cochlear implantation, objective methods such as ECAP, ESRT, EABR combined with subjective psychological physical test all together are helpful to obtain accurate threshold.

OBJECTIVETo investigate the changes in contents of cycloxygenase-2 (COX-2) and its downstream effectors in rat's myocardial ischemia/reperfusion (I/R) model and observe the effects of precondition with GBE50 (Ginkgo biloba extract 50) and Salviae miltiorrhizae (SM) on them.

METHODSRat's I/R model was established by 30-min left anterior descending coronary artery occlusion followed with 60-min reperfusion. Animals were divided into the model control group, the sham-operated group and the tested groups (received 1-week precondition with GBE50 and SM respectively via intragastric infusion before modeling). COX-2 mRNA expression in myocardium was detected by real-time PCR; contents of thromboxane B2 (TXB2) and 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha) were measured by radioimmunoassay.

RESULTSThe mRNA expression of COX-2 in the model group was obviously higher than that in the sham-operated group (P < 0.001), while that in the tested groups was down-regulated significantly (P < 0.01), and the content of TXB2 as well as the ratio of TXB2/PGF1alpha was reduced significantly (P < 0.05). Besides, SM also showed the up-regulation effect on 6-keto-PGF1alpha content in myocardium (P < 0.05).

CONCLUSIONCOX-2 affects the myocardium through thromboxane A2 and prostacyclin after I/R; both GBE50 and SM can inhibit the production of COX-2, but they may act in different paths.

OBJECTIVETo explore the adverse effects of coking oven emissions (COE) on the serum oxidation-reduction and relevant genes in the exposed workers.

METHODSFifty-six coke oven workers and forty controls were investigated. Serum Malondialdehyde (MDA) levels and the activities of total superoxide dismutases (T-SOD) were measured by spectrophotometrical method. Immunohistochemical method was used to assess the P21 and P53 levels in peripheral white blood cells.

RESULTSCompared with controls, the individuals exposed to COE had significantly increased levels of serum MDA [(5.30 +/- 2.29) nmol/mL, P < 0.01] and markedly decreased levels of T-SOD [(100.04 +/- 10.75) NU/mL]. Additionally, the median levels of P53 and P21 were markedly increased in the exposed individuals compared with the controls (21.4% and 23.2%, respectively, all P < 0.05).

CONCLUSIONThe findings indicate that occupational exposure to COE causes the rise of serum oxidation-reduction MDA and the fall of T-SOD, and increasing expression levels of P21 and P53 proteins before the occurrence of apparent clinical symptoms.

OBJECTIVETo probe into the current situation and problems of establishing control group in clinical studies of acupuncture and moxibustion for treatment of periarthritis of shoulder at home.

METHODSTo retrieve the literatures of establishing control groups in clinical studies of acupuncture and moxibustion for treatment of periarthritis of shoulder in magazines at home, and based on key problems in establishment of control group, make a Excel form to take out relative contents in the literatures and classify, summarize and statistically analyze.

RESULTSIn establishing control group in clinical studies of acupuncture and moxibustion for treatment of periarthritis of shoulder, a lot of problems exist, most studies do not have the basis of establishing control group, and also do not establish control group for the purpose of the study, making the whole test have error in the stage of program design, and leading to unreliable for the results of clinical control studies.

CONCLUSIONIn clinical researches of acupuncture and moxibustion, a standard for guiding establishment of control group is eagerly needed.

Mesenchymal stem cells (MSC) are the ideal adult stem cells in cell/gene therapy and tissue engineering for their features of easily-handling, highly proliferative capacity in vitro, low immunogenicity and immunomodulatory ability. MSC, as a kind of cellular drug, have been utilized in a phase III clinical trial to treat refractory graft-versus-host disease (GVHD). However, the essences of MSC in culture remain elusive so far. Whether the cells expanded in vitro are stem cells per se, and if not, why expanded MSC maintain their multiple differentiation ability? And are the MSC cultivated in vitro homogeneous and if not, what the heterogeneity stands for? Focusing on the heterogeneity of MSC in culture in vitro, the above questions are briefly discussed in this review.

OBJECTIVETo evaluate the safety and efficacy between endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincteropapillotomy ( EST) for common bile duct stones using meta-analysis method.

METHODSRandomizd controlled trials comparing EPBD with EST for common bile duct stones and published from January 1990 to July 2012 were recruited. This meta-analysis was conducted to estimate short-term and long-term complications. Fixed random effect model or random effect model was established to analyze the data.

RESULTSTwelve randomizd controlled trials were included in this analysis. These studies included 1865 patients, 925 of them were treated with EPBD and 940 were treated with EST. The analysis of basic characteristics of these included studies showed that: compared to EST, patients in the EPBD group were younger (OR = -1.16, 95% CI: -1.49 to -0.84, P = 0.00), while in two groups, there were no significant difference (P > 0.05) in gender proportion, average size of stones, number of gallstones, previous cholecystectomy, the number of merged duodenal diverticulum, common bile duct diameter, the total follow-up time. Also, compared to EST, the overall stone clearance in the EPBD group was lower (OR = 0.64, 95% CI: 0.42 to 0.96, P = 0.03), pancreatitis incidence was higher (OR = 2.67, 95% CI: 1.61 to 4.43, P = 0.00), incidence of bleeding (OR = 0.12, 95% CI: 0.04 to 0.34, P = 0.00), acute cholecystitis (OR= 0.39, 95% CI: 0.18 to 0.84, P = 0.02), total long-term complication rate (OR = 0.53, 95% CI: 0.36 to 0.77, P = 0.01), stone recurrence rate more than a year were lower (OR= 0.48, 95% CI: 0.26 to 0.90, P = 0.02). While in two groups, there were no significant difference (P > 0.05) in the stone removal on 1 '' attempt, the total near-term complications and acute cholangitis.

CONCLUSIONSOn the basis of lower rates of bleeding, EPBD seems to be preferred strategy over EST for endoscopic remove of common bile duct stones in patients who have coagulopathy. Although stone recurrence rate more than a year of EPBD is lower, but the overall stone clearance rate is lower and the risk of pancreatitis is higher than that of EST.
