Two-stage vs single-stage management for concomitant gallstones and common bile duct stones

AIM:To evaluate the safety and effectiveness of twostage vs single-stage management for concomitant gallstones and common bile duct stones.METHODS:Four databases,including PubMed,Embase,the Cochrane Central Register of Controlled Trials and the Science Citation Index up to September 2011,were searched to identify all randomized controlled trials(RCTs).Data were extracted from the studies by two independent reviewers.The primary outcomes were stone clearance from the common bile duct,postoperative morbidity and mortality.The secondary outcomes were conversion to other procedures,number of procedures per patient,length of hospital stay,total operative time,hospitalization charges,patient acceptance and quality of life scores.RESULTS:Seven eligible RCTs [five trials(n = 621) comparing preoperative endoscopic retrograde cholangiopancreatography(ERCP)/endoscopic sphincterotomy(EST) + laparoscopic cholecystectomy(LC) with LC + laparoscopic common bile duct exploration(LCBDE);two trials(n = 166) comparing postoperative ERCP/EST + LC with LC + LCBDE],composed of 787 patients in total,were included in the final analysis.The metaanalysis detected no statistically significant difference between the two groups in stone clearance from the common bile duct [risk ratios(RR) =-0.10,95% confidence intervals(CI):-0.24 to 0.04,P = 0.17],postoperative morbidity(RR = 0.79,95% CI:0.58 to 1.10,P = 0.16),mortality(RR = 2.19,95% CI:0.33 to 14.67,P = 0.42),conversion to other procedures(RR = 1.21,95% CI:0.54 to 2.70,P = 0.39),length of hospital stay(MD = 0.99,95% CI:-1.59 to 3.57,P = 0.45),total operative time(MD = 12.14,95% CI:-1.83 to 26.10,P = 0.09).Two-stage(LC + ERCP/EST) management clearly required more procedures per patient than single-stage(LC + LCBDE) management.CONCLUSION:Single-stage management is equivalent to two-stage management but requires fewer procedures.However,patient's condition,operator's expertise and local resources should be taken into account in making treatment decisions.

Top-cited Articles in Chemical Engineering in Science Citation Index Expanded:A Bibliometric Analysis

This study aimed to identify and to analyze characteristics of top-cited articles published in the Web of Science chemical engineering subject category from 1899 to 2011.Articles that have been cited more than 100 times were assessed regarding publication outputs,and distribution of outputs in journals.Five bibliometric indicators were used to evaluate source countries,institution and authors.A new indicator,Y-index,was created to assess quantity and quality of contribution to articles.Results showed that 3828 articles,published between 1931 and 2010,had been cited at least 100 times.Among them 54% published before 1991,and 49% top-cited articles originated from US.The top eight productive institutions were all located in US.The top journals were Journal of Catalysis,AIChE Journal,Chemical Engineering Science and Journal of Membrane Science.Y-index was successfully applied to evaluate publication character of authors,institutions,and countries/regions.

Three initial diets for management of mild acute pancreatitis:A meta-analysis

AIM:To compare non-liquid and clear-liquid diets,and to assess whether the latter is the optimal treatment for mild acute pancreatitis.METHODS:The Cochrane Library,PUBMED,EMBASE,EBM review databases,Science Citation Index Expanded,and several Chinese databases were searched up to March 2011.Randomized controlled trials(RCTs) that compared non-liquid with clear-liquid diets in patients with mild acute pancreatitis were included.A meta-analysis was performed using available evidence from RCTs.RESULTS:Three RCTs of adequate quality involving a total of 362 participants were included in the final analysis.Compared to liquid diet,non-liquid diet significantly decreased the length of hospitalization [mean difference(MD):1.18,95% CI:0.82-1.55;P﹤0.00001] and total length of hospitalization(MD:1.31,95% CI:0.45-2.17;P = 0.003).The subgroup analysis showed solid diet was more favorable than clear liquid diet in the length of hospitalization,with a pooled MD being-1.05(95% CI:-1.43 to-0.66;P﹤0.00001).However,compared with clear liquid diet,both soft and solid diets did not show any significant differences for recurrence of pain after re-feeding,either alone [relative risk(RR):0.95;95% CI:0.51-1.87;P = 0.88] and(RR:1.22;95% CI:0.69-2.16;P = 0.49),respectively,or analyzed together as non-liquid diet(RR:0.80;95% CI:0.47-1.36;P = 0.41).CONCLUSION:The non-liquid soft or solid diet did not increase pain recurrence after re-feeding,compared with the clear-liquid diet.The non-liquid diet reduced hospitalization.

Coffee drinking and pancreatic cancer risk:A meta-analysis of cohort studies

AIM:To quantitatively assess the relationship between coffee consumption and incidence of pancreatic cancer in a meta-analysis of cohort studies. METHODS:We searched MEDLINE,EMBASE,Science Citation Index Expanded and bibliographies of retrieved articles.Studies were included if they reported relative risks(RRs)and corresponding 95%CIs of pancreatic cancer with respect to frequency of coffee intake.We performed random-effects meta-analyses and metaregressions of study-specific incremental estimates to determine the risk of pancreatic cancer associated with a 1 cup/d increment in coffee consumption. RESULTS:Fourteen studies met the inclusion criteria, which included 671 080 individuals(1496 cancer events) with an average follow-up of 14.9 years.Compared with individuals who did not drink or seldom drank coffee per day,the pooled RR of pancreatic cancer was 0.82 (95%CI:0.69-0.95)for regular coffee drinkers,0.86 (0.76-0.96)for low to moderate coffee drinkers,and 0.68(0.51-0.84)for high drinkers.In subgroup analyses,we noted that,coffee drinking was associated witha reduced risk of pancreatic cancer in men,while this association was not seen in women.These associations were also similar in studies from North America,Europe, and the Asia-Pacific region. CONCLUSION:Findings from this meta-analysis suggest that there is an inverse relationship between coffee drinking and risk of pancreatic cancer.

A meta-analysis of the effects of energy intake on risk of digestive cancers

AIM:To quantitatively assess the relationship between energy intake and the incidence of digestive cancers in a meta-analysis of cohort studies.METHODS:We searched MEDLINE,EMBASE,Science Citation Index Expanded,and the bibliographies of retrieved articles.Studies were included if they reported relative risks(RRs) and corresponding 95% CIs of digestive cancers with respect to total energy intake.When RRs were not available in the published article,they were computed from the exposure distributions.Data were extracted independently by two investigators and discrepancies were resolved by discussion with a third investigator.We performed fixed-effects meta-analyses and meta-regressions to compute the summary RR for highest versus lowest category of energy intake and for per unit energy intake and digestive cancer incidence by giving each study-specific RR a weight that was proportional to its precision.RESULTS:Nineteen studies consisting of 13 independent cohorts met the inclusion criteria.The studiesincluded 995 577 participants and 5620 incident cases of digestive cancer with an average follow-up of 11.1 years.A significant inverse association was observed between energy intake and the incidence of digestive cancers.The RR of digestive cancers for the highest compared to the lowest caloric intake category was 0.90(95% CI 0.81-0.98,P < 0.05).The RR for an increment of 239 kcal/d energy intake was 0.97(95% CI 0.95-0.99,P < 0.05) in the fixed model.In subgroup analyses,we noted that energy intake was associated with a reduced risk of colorectal cancer(RR 0.90,95% CI 0.81-0.99,P < 0.05) and an increased risk of gastric cancer(RR 1.19,95% CI 1.08-1.31,P < 0.01).There appeared to be no association with esophageal(RR 0.96,95% CI 0.86-1.07,P > 0.05) or pancreatic(RR 0.79,95% CI 0.49-1.09,P > 0.05) cancer.Associations were also similar in studies from North America and Europe.The RR was 1.02(95% CI 0.79-1.25,P > 0.05) when considering the six studies conducted in North America and 0.87(95% CI 0.77-0.98,P < 0.05) for the five studies from Europe.CONCLUSION:Our findings suggest that high energy intake may reduce the total digestive cancer incidence and has a preventive effect on colorectal cancer.

What does SCI mean to a doctor in China?

In China, to be an excellent doctor means to publish Science Citation Index （SCI） paper as much as possible. The scientific evaluation system based on the number of SCI publications becomes the only criteria for ranking position of Chinese doctors. Who can save them from the slavery of SCI？

Case-based learning in education of Traditional Chinese Medicine: a systematic review

OBJECTIVE:To assess the effect of case-based learning(CBL)in the education of Traditional Chinese Medicine(TCM).METHODS:The studies concerning TCM courses designed with CBL were included by searching the databases of EBSCO,Pubmed,Science Citation Index,China National Knowledge Infrastructure,Chongqing VIP database.The valid data was extracted in accordance with the included criteria.The quality of the studies was assessed with Gemma Flores-Masteo.RESULTS:A total of 22 articles were retrieved that met the selection criteria:one was of high quality;two were of low quality;the rest were categorized as moderate quality.The majority of the studiesdemonstrated the better effect produced by CBL,while a few studies showed no difference,compared with the didactic format.All included studies confirmed the favorable effect on learners'attitude,skills and ability.CONCLUSION:CBL showed the desirable results in achieving the goal of learning.Compared to didactic approach,it played a more active role in promoting students'competency.Since the quality of the articles on which the study was based was not so high,the findings still need further research to become substantiated.

Comparative literature study between investigations in foreign Science Citation Index journals and Chinese core domestic journals in the treatment of low back pain with acupuncture

OBJECTIVE： To investigate the quality and meth- ods of clinical research literature published in for- eign Science Citation Index （SCI） journals studying the treatment of low back pain with acupuncture. To conduct a comparative study with clinical re- search literature published in Chinese core domes- tic journals, and to understand the prospects of cur- rent research trends of acupuncture clinical studies in Western countries and China. METHODS： Studies on clinical acupuncture treat- ment of low back pain in English SCI journals and four Chinese core domestic journals dated from 2002 to 2012 were sourced and summarized for this study. Objective analysis and evaluation on the differences in subject and scope of study on low back pain by foreign and Chinese researchers were conducted. RESULTS： Forty-seven English studies and 115 Chi- nese studies met our inclusion criteria. A keyword search revealed different kinds of low back pain re- lated conditions in English and Chinese studies. The English studies were broad in scope, while the Chinese studies were more focused. There were al-so differences in the understanding and definition of concepts and study orientation. CONCI.IJSION： More study should be undertaken to understand the contradictions that acupuncture faces in view of modern research to further ad- vance the field.

Analysis of Moxibustion Reports Published in Journals of Science Citation Index in Recent 5 Years

Objective： To analyze moxibustion reports published in the journals of Science Citation Index （SCI）, so as to grasp the current publication development of researches on moxibustion and to provide submission reference to such studies in the future. Methods： Moxibustion reports were searched on PubMed and ISI web of knowledge, and 2 reviewers extracted data independently for analysis. Studies qualified were analyzed from eight aspects： publishing amount, research type, source journal, impact factor （IF）, source country, source academy, indication and effect evaluation, comparison of studies between China and other countries. Results and Conclusion： Fifty-three associated reports published in journals of SC1 were selected. The publishing amount of moxibustion reports increased year by year, and majority of these reports were clinical researches and system reviews. IFs of most journals were less than 5. Diseases involved were various; however, the curative effect of moxibustion was still uncertain worldwide. The mechanism of moxibustion was not fully described, either. Further high-quality and convictive researches were still needed to define the curative effect of moxibustion and to increase the SCI publishing amounts.

Papers published from 1995 to 2012 by six Traditional Chinese Medicine universities in China: a bibliometric analysis based on science citation index

OBJECTIVE: The quality and quantity of published research papers are important in both scientific and technology fields. Although there are several bibliometric studies based on citation analysis, very few have focused on research related to Traditional Chinese Medicine in China. METHODS: The bibliometric method used in this study included the following focuses: publication outputs for each year, paper type, language of publication, distribution of internationally collaborative countries, sources of funding, authorization number, distribution of institutes regarding collaborative publications, research fields, distribution of out-puts in journals, citation data, and h-index. RESULTS: A total of 3809 papers published from 1995 to 2012 were extracted from the science citation index(SCI). The cumulative number of papers from all six universities is constantly increasing. The United States attained the dominant position regarding complementary and alternative medicine research. The Chinese Academy of Sciences was the greatest participator in collaborative efforts. Research field analysis showed that the research mainly focused on pharmacology pharmacy, chemistry, integrative complementary medicine, plant sciences, and biochemistry molecular biology. The Shanghai University of Chinese Medicine had the most citations. CONCLUSION: In recent years, in terms of SCI papers, the six Traditional Chinese Medicine universities studied here have made great advances in scientific research.
