Objective To evaluate the efficacy of probiotics to treat irritable bowel syndrome (IBS).Methods Publications from database including PubMed,the Cochrane Library,Embase,CNKI,CBM and WanFang Data were searched up to August 31,2014.The randomized controlled trials (RCTs) on probiotics to treat IBS were eligible.The related articles were extracted and cross-checked independently by two reviewers.Methodological quality of trials was evaluated according to Cochrane Handbook 5.1.0 criteria.Meta-analysis was conducted using RevMan 5.2 software.Results A total of 17 RCTs involving 1 700 patients were included.Results of meta-analyses showed that compared with the placebo,probiotics was statistically better in improving the overall symptoms integral (SMD =-0.20,95％ CI-0.33--0.07,P =0.002),alleviating abdominal pain/discomfort (SMD =-0.19,95％ CI-0.29--0.09,P ＜ 0.001),relieving abdominal distention (SMD =-0.16,95％ CI-0.28--0.03,P =0.020),and defecation discomfort (SMD =-0.22,95％ CI-0.42--0.02,P =0.030).There was no statistical significance in the overall quality of life (SMD =-0.08,95％ CI-0.07-0.23,P =0.290) and adverse effect ratio (RR =1.08,95％CI0.79-1.49,P=0.630).Conclusion Probiotics have beneficial effects on IBS,which can improve the patients' symptoms and with less adverse reaction.Due to the bias,further large-scale,multicenter and high-quality RCTs are required to unify outcome indicators,further define sensitive strain,and standardize its usage,dosage and course of treatment.

Objective To study the method of operation and effect of the application of resonant liposuction in the body figure reconstruction. Methods Resonant liposuction was employed in 136 cases, including local fat deposit in some part of the body. Operation's safety, mircotrauma, speediness, and effect after operation were observed. Results The follow-up for 6 to 24 months showed that the reconstructed body figure was very satisfactory. Conclusion Resonant liposuction is an ideal method to reconstruct the body figure owing to its safety, miniinvasion, easy performance and efficacy.

Objective To observe the changes of blood fentanyl concentration in rats during anhepatic phase by treatment of large dose of dexamethasone and to investigate the extrahepatic metabolism of fentanyl. Methods Thirty rats were randomly divided into 3 groups (n=10 in each group): normal control group (Group A), anhepatic phase group (Group B), anhepatic phase+dexamethasone treatment group (Group C). The hepatic portal of rats was dissociated and closed in Group B. In Group C, 20 mg/kg of dexamethasone was infused 1 h before the occlusion of hepatic portal. After intravenous injection of 20 ?g/kg fentanyl each time, the blood samples were collected. The fentanyl blood concentration was analyzed by HPLC. Results The blood fentanyl concentration of anhepatic phase dropped more slowly in Group B than Group C (P0.05). Conclusion The liver is the main organ for fentanyl metabolism. There is the extrahepatic metabolism for fentanyl and dexamethasone can enhance the extrahepatic metabolism of fentanyl.

OBJECTIVE:To study the effect of penehyclidine on the level of cytokines in infants with congenital heart disease undergoing cardiopulmonary bypass(CPB).METHODS:A total of 60 children with congenital heart disease(CHD)were divided into three groups:Group P1(intramuscularly injected with penehyclidine before operation),Group P2(intramuscularly injected with penehyclidine before and after operation),and Group C(intramuscularly injected with atropine before operation).The levels of cytokine were determined at different time.Postoperative salivary secretion and X-ray of chest were observed.RESULTS:After CPB,the levels of the inflammatory cytokine in all the three groups were significantly higher,with those in Group P1 and P2 significantly lower than in Group C(P

Objective To investigate the expression of DR5 and DcR2 protein and mRNA in lumbar intervertebral disc (LID) of patients with prolapse of LID and normal controls.Methods The expression and distribution of DR5 and DcR2 protein were immunostained in prolapsed LIDs of 60 patients and 22 normal LIDs of 8 normal controls. In parallel, mRNA of DR5 and DcR2 was quantified by real time fluorescent reverse transcriptase-polymerase chain reaction (RT-PCR) in prolapsed LIDs of 30 patients and 9 normal LIDs of 3 normal controls.Results The positive rates of DR5 protein in prolapsed IVDs and normal IVDs were 41.60% and 26.09% respectively. There were a significant difference between the two groups ( P=0.001). Further similar evidences were obtained by quantification of DR5 mRNA ( P=0.025). There was no difference in the expression of DcR2 protein and mRNA between the two groups.Conclusion The apoptosis pathway induced by DR5/tumor necrotic factor-related apoptosis-inducing ligand (TRAIL) maybe exists in LID tissues.

Objective To investigate the characteristic of P30o event-related potentials(ERP) of impulsive behavior in heroin addicts.Methods The Iowa gambling task (IGT) were performed by using the paradigm for psychological experiment both in heroin addiction group (HA group) and health control group (HC group),the inspection of electroencephalography were underwent in all the subjects concurrently.Following the collection of data of ERP,amplitude and latency of P300 were compared between the two groups,and then the relationship betweenamplitude or latency of P300 and the results of Barratt impulsiveness scale were analyzed separately.Results Compared to HC group,BIS score as well as the numbers of high frequency loss cards were significantly higher in HA group ( HA:75.12 ± 12.49,91.14 ± 21.35 ; HC:66.54 ± 8.61,73.71 ± 18.91 ; P ＜ 0.05 ),while the both two groups had visible waveforms of P30o,and the amplitude and latency were markedly lower ( HA:4.92 ± 1.14,293.43 ± 36.21 ; HC:7.65 ± 1.59,332.68 ± 40.15 ; P ＜ 0.05 ) and were negatively associated with BIS score in HA group( r =-0.76,-0.52,P＜ 0.05).Logistic regression results showed that the scores of BIS-11 were related to amplitude of P30o merely( P ＜ 0.05 ).Conclusion Impulsive behavior can be observed from the abnormal characteristic of the P300 event-related potential of impulsive behavior in heroin addicts,which may partly contribute to both addiction and relapse of heroin addict.

objective To investigate the clinical relevance of antinuclear antibodies (ANA)in patients with systemic sclerosis(SSc).Methods Clinical data were collected from 283 patients with SSc admitted to Peking Union Medical College Hospital(PUMCH)from 1981 to 2009.A retrospective analysis was carried out.Results In the 283 patients,253(89.4%)were female.The mean age at onset was 35.9±12.6 years and mean disease duration 4.3 ±4.5 years.There were 125(44.2%)patients with diffuse SSc(dcSSc) and 158(55.8%)with limited cutaneous SSc(lcSSc).Of all the patients,96.8%were positive for ANA,54.4% for anti-Scl-70 antibodies,6.4%for anticentromere antibodies(ACA),23.7%for anti-ribonucleoprotein(RNP) antibodies,7.1%for anti-Sm antibodies,25.1%for anti-SSA antibodies,7.1%for anti.SSB antibodies,and 1.1%for anti-Jo-1 antibodies.No patients were positive for anti-rRNP antibodies.Only one patient was positive for both anti-Scl-70 antibodies and ACA.The positivity rate of ACA in patients with leSSe was higher thanthat in those with dcSSc(P<0.05).Conclusion The detection of antinuclear antibodies is helpful for the diagnosis,classification,prognosis evaluation and management of SSc.
