Objective To assess the quality of randomized controlled trials(RCT)abstracts published in Journal of Clinical Anesthesiology by CONSORT for Abstracts.Methods Articles invol-ving human RCTs published from 2012 to 2013 were reviewed and searched through WanFang Med Online.Trials involving animal experiments,in vitro,RCTs without abstract,and meta-analyses were excluded.According to the CONSORT checklists for abstracts,the quality of abstracts for RCT were assessed.Results In total,392 RCT abstracts were analysed.The median word counts of ab-stracts was 364 (IQR 306-444),sample size was 60 (IQR 40-80).Almost all abstracts provided an appropriate description of conclusions (100%), numbers randomized (99.0%) and objective (99.0%).The majority of abstracts described interventions (94.6%)and participants (82.4%).Re-quirements present in less than 50% of the abstracts were details regarding trial design (46.2%)and harms (48.7%).The descriptions of randomization (13.3%),blinding (1.8%),methods-outcome (3.6%)and results-outcome (9.7%)were very low.Moreover,title,recruitment and numbers ana-lysed were not reported.Conclusion The quality of RCT abstracts and adherence to the CONSORT checklist for abstracts remains poor,and the CONSORT for Abstracts should be endorsed to improve the quality of RCT abstracts as early as possible.

Objective To investigate the therapeutic effect of immunodepressant on Crohn's disease (CD).Methods 105 patients with CD were collected from 1983 to 2006 in Peking Union Medical College Hospital.All of their clinical manifestations and therapeutic results were analyzed retrospectively.Results (1)The application of immunedepressant was significantly increased after the year of 2000 (34.7% vs 3.0%,P=0.000).(2)The application of immunodepressant and the clinical features of these patients were as fouows：①The number of patients with modcrate to severe CD were more than that with mild CD in those using immunodepressant (28.9% vs 0).②The use of immunodepressant was not related with the diseased site of CD.because there were no difference among the groups with lesion in small intestine (20.0%),colon(27.3%)and ileocolon(27.1%),P=0.726.③The serum albumin level of CD patients using immunodepressant was significantly lower than that of those not using(31.9 g/L vs 35.1 g/L,P=0.047).④The use of immunodepressant did not decrease the incidenee of operative treatment(38.5% vs 50.0%,P=0.320).(3)The rate of remission in 19 CD patients using azathioprine is 68.4%(13/19)and the percentage of neutrophil in the group with relief was lower than that without relief(0.76 vs 0.65,P=0.032).Conclusions Immunodepressant is playing more important role in the treatment of CD.The patients with moderate and severe CD with as well as lower serum albumin should be treated with immunodepressant as early as possible.Whether immunedepressant is necessary or not is not decided by the diseased site.CD patients with higher percentage of neutrophil have less therapeutic effect than those with lower.

Objective To investigate the causes, clinical features, treatment and prognosis of gastrointestinal bleeding (GIB) patients in emergency department.Methods To analyze prospectively the clinical data of 168 GIB patients admitted to the emergency department of Peking Union Medical College Hospital during 2006.1-2006.12.Results (1) General data; male: female = 1.75:1 ( 107: 61) , mean age 13-87(56.5 ±17.8) years with a peak in 60-69 years.The percentage of old patients was significantly higher than that of young and middle age ( 52.4% vs 19.6% and 28.0% , P = 0.000 ).( 2 ) The incidence of acute gastric mucosal lesion in patients taking non-steroidal antiinflammatory drugs ( NSAIDs) ( 18.5% ) was significantly higher than that in patients not taking( 0.7% , P = 0.000 ).( 3 ) 86.9% ( 146/168 ) of the patients had anemia.(4) More patients who took emergency gastroscopy could be diagnosed than those patients who did not (89.4% vs 58.5% , P =0.000), while no significant difference could be seen between patients who took emergency enteroscopy and patients who had non-emergency gastroscopy (20.0% vs 57.9% , P =0.315).(5)The hemostatic ratio in GIB patients due to peptic ulcer was obviously higher than that in GIB patients due to other causes (86.0% vs 40.7% ,P =0.000).The rate of emergency operation for GIB patients was 1.8%.Conclusions Most of the GIB patients admitted to tertiary general hospitals are elderly males.NSAIDs administration is one of the most important causes of upper GIB.Upper GIB patients should have gastroscopy as soon as possible, while emergency coloscopy is of little significance in cases with lower gastrointestinal hemorrhage.

Objective Matrix-assisted laser desorption ionization-time of might-mass spectrometry (MALDI-TOF-MS) was utilized to analyze the protein fingerprint in brain-gut interaction of irritable bowel syndrome (IBS) model rats' colon, so as to find the clues for IBS. Methods Fourteen healthy male adult Wistar rats were selected and divided into a control and a chronic and acute stress ( CAS) group. Colon motility, visceral sensation and behavior changes of rats were detected to evaluate the model. MALDI-TOF-MS was used to observe the overall view of protein in colon so as to study whether there are abnormalities of protein levels in IBS. Results As compared with those in the control group, the number of fecal pellets [ (6. 00 ± 1. 69 ) pellets/1 h vs ( 1. 14 ± 0. 69 ) pellets/1 h, P < 0. 01 ] and frequency of abdominal contraction induced by colorectal distention (CRD) increased, while the amount of weight gain [ (298. 88 ± 18.61)gvs (348. 00±12. 44)g, P<0.01] and consumption of sucrose solutions [ (13. 63 ± 1. 69) ml/1 h vs (19.00±3.06) ml/1 h, P<0.05] decreased in the CAS group (P <0. 05). As far as protein/peptide quality different peak was concerned, CAS rats had 12 different peaks compared with the control rats. The different proteins could be divided into 4 types, which were related to iron secretion, protein synthesis, G protein system and immunity. The protein levels of the model group were higher than those in the control group (P < 0. 05). Conclusions The CAS rats integrate the major characteristics of IBS such as altered colon motility, higher visceral hypersensitivity and psychiatric disorder and can mimic the brain-gut interaction of IBS partly. The detection of differential proteins provides reference for the pathogenesis and treatment of IBS.

In this study, researchers adopted the network analysis method to study Buyang Huanwu decoction at three levels, namely chemical ingredients, targets and diseases, and discovered the potential effect of Buyang Huanwu decoction in cancer treatment. Besides, they analyzed the "target-target" network of Buyang Huanwu decoction based on diseases, calculated four network indexes, namely node centrality, closeness centrality, betweenness centrality and eigenvector centrality for a comprehensive evaluation on the importance and significance of each target in the network. Afterwards, key targets of Buyang Huanwu decoction were excavated to obtain two important targets--COX-2 and PPAR-gamma, which may be important targets involved in the qi deficiency and blood stasis diseases. Meanwhile, the two targets were the basis to build the core network of "chemical component-target-disease" of Buyang Huanwu decoction, which provided reference for further studies on the effect of Buyang Huanwu decoction in treating qi deficiency and blood stasis diseases. According to the study, the network analysis method was helpful to excavate potential targets Buyang Huanwu decoction in treating qi deficiency and blood stasis diseases, and could provide methodological reference for revealing the mechanism of Buyang Huanwu decoction at multiple levels, with a guiding significance for interpreting mechanisms of traditional Chinese medicinal formulae and developing new drugs.

Objective:To explore the expression of N-cadherin and its correlations with the clinicopathological features of human ovarian carcinoma.Methods:The expression of N-cadherin in 281 cases of ovarian carcinoma tissues were determined by immunohistochemical method.The correlations of N-cadherin expression with the clinicopathological features of human ovarian carcinoma were analyzed.Results:There was higher expression of N-cadherin in the metastatic lesions than its paired primary lesions (P =0.018).The expression level of N-cadherin in ovarian carcinoma was correlated with the FIGO stage (P =0.034),histological type (P ＜0.001) and tumor grade (P =0.004).Conclusions:High expression of N-cadherin might positively correlate with the invasion and migration ability of ovarian carcinoma cells,which was more common in the the advanced (FIGO Ⅱ-Ⅳ) ovarian carcinoma,high-grade serous carcinoma,and high grade ovarian carcinoma.N-cadherin might be useful in estimating the biological behavior of human ovarian carcinoma.

Objective To elucidate the prevalence and clinical characteristics of human metapneumovirus(hMPV)in hospital- ized children with respiratory infection.Methods A total of 452 hospitalized children with lower respiratory tract infection were observed from Aug 2004 to Jan 2005.Respiratory tract aspirates were collected from all patients within 48 hours after admis sion.The specimens were routinely tested for respiratory syncytial virus,influenza virus A and B,parainfluenza virus 1 to 3 and adenovirus by direct fluorescent assay(DFA).The 245 specimens negative by DFA were tested for hMPV by RT-PCR. PCR products of hMPV M gene from some patients were randomly selected for sequencing analysis.Results hMPV was identi- fied in 59(24.1%)of the 245 specimens tested,hMPV infection alone accounted for 13.1% of the infections in the 452 chil- dren under study,The prevalence of hMPV was higher than other respiratory viruses in winter.The mean age of hMPV-infec- ted children(n=59)was 27.7 months.There was no significant difference between age groups in terms of the prevalence of hMPV(P＞0.05).There were no statistically significant difference in demographics and clinical symptoms between hMPV in- fection and other common respiratory virus infection.Genotyping for the hMPV M gene from 23 Shanghai patients showed two distinct hMPV genotypes.Sequence analysis of these hMPV M genes showed 82.8%-100% homology to the registered se- quence in GenBank.There was no significant difference in clinical characteristics between the 2 genotypes.Conclusions hMPV plays an important pathogenic role in lower respiratory tract infection of children,hMPV prevailed in the winter of 2004.Clini- cally,hMPV infection can not be discriminated from the infection of other respiratory viruses.Clinical manifestation is similar between the two hMPV genotypes.
