OBJECTIVE: To compare cyclooxygenase-2 (Cox-2) inhibitors alone with NSAIDs plus proton pump inhibitors (PPIs) in preventing gastrointestinal adverse events: upper gastrointestinal (UGI) adverse events and gastrointestinal symptoms in Osteoarthritis and Rheumatoid arthritis. METHODS: PubMed, the Cochrane Library, EMBASE, ISI Web of Knowledge, Chinese Biomedical Literature Database, and reference lists of relevant papers for articles published 1990-2010.12 were searched. The related data matching standards set for this study were extracted. Statistical analyses were carried out using RevMan (5.0) software. RESULTS: The meta-analysis of six randomized controlled trials with a total of 6219 patients revealed that there was no difference in the UGI adverse events between Cox-2 inhibitors and nonselective NSAIDs with concurrent use of PPIs [relative risk (RR) 0.61, 95% confidence interval (CI) 0.34-1.09]. There was no significant difference in gastrointestinal symptoms (RR 1.10, 95% CI: 0.88-1.39) and the cardiovascular adverse events (RR 1.67, 95% CI: 0.78-3.59) between the two groups. CONCLUSION: Cox-2 inhibitors are no better than nonselective NSAIDs with PPIs in regard to UGI adverse events, gastrointestinal symptoms and cardiovascular adverse events in Osteoarthritis and Rheumatoid arthritis. On the basis of the current evidence and the combined wishes of the patient, clinicians should carefully consider and weigh both gastrointestinal and cardiovascular risk before selecting NSAID plus PPIs or Cox-2 inhibitors. © 2011 Wolters Kluwer Health | Lippincott Williams &Wilkins.

Objective: We pooled the data from published studies to estimate the prognostic value of fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) or PET/ computed tomography (CT) in cervical cancer patients. Methods: We searched MEDLINE, EMBASE, and PUBMED to identify studies investigating the association of 18F-FDG PET or PET/CT with clinical survival outcomes of patients with cervical cancer. The summarized hazard ratio (HR) was estimated by using fixed- or random-effect model according to heterogeneity between trails. Results: We analyzed a total number of 1854 patients from 16 studies and found that positive pretreatment FDG-PET images were significantly associated with poorer event-free survival (hazard ratio [HR], 2.681; 95% confidence interval [CI], 2.059Y3.490) and overall survival (HR, 2.063; 95% CI, 1.023Y4.158). Furthermore, metabolic response of therapy as shown on posttreatment PET images was also capable of predicting event-free survival and overall survival with statistical significance, and the HR was 2.030 (95% CI, 1.537Y2.681) and 2.322 (95% CI, 1.485Y3.630), respectively. Conclusions: Uptake of 18F-FDG on PETor PET/CTeither before or after treatment has a promising value of both predicting survival outcomes for patients with cervical cancer and identifying patients for more aggressive treatment.

MiR-130a has been demonstrated to play important roles in many types of cancers. Nevertheless, its biological function in breast cancer remains largely unknown. In this study, we found that the expression level of miR-130a was down-regulated in breast cancer tissues and cells. Overexpression of miR-130a was able to inhibit cell proliferation, invasion and migration in MCF7 and MDA-MB-435 cells. With the bioinformatics analysis, we further identified that RAB5A was a directly target of miR-130a, and its mRNA and protein level was negatively regulated by miR-130a. Immunohistochemistry verified RAB5A was upregulated in breast cancer tissues. Therefore, the data reported here demonstrate that miR-130a is an important tumor suppressor in breast cancer, and imply that miR-130a/RAB5A axis have potential as therapeutic targets for breast cancer.

Objective To systematically evaluate the correlation between endometriosis (EM) in Chinese women and Xba I polymorphism in intron-1 of estrogen receptor a (ER-α) gene. Methods Such databases as PubMed, MEDLINE, The Cochrane Library (Issue 3, 2012), VIP, CBM, WanFang Data and CNKI were searched to collect case-control studies about the correlation between EM and Xba I polymorphism in intron-1 of ER-α gene. The retrieval time was from 1980 to 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.0 and Stata 12.0 software. Results A total of 7 studies involving 676 EM patients and 688 healthy volunteers were included. The results of meta-analyses showed that Chinese women with X/X genotype had similar risk of EM compared to those with x/x genotype (OR=0.95, 95%CI 0.58 to 1.54, P=0.82) or X/x genotype (OR=0.73, 95%CI 0.44 to 1.20, P=0.22). The allele X also showed similar risk of EM compared to the allele x (OR=1.11, 95%CI 0.93 to 1.33, P=0.25). Conclusion At present, it has not yet been found that the incidence of EM in Chinese women is related to the Xba I polymorphism in intron-1 of ER-α gene as well as the allele X For the quantity and quality limitation of the included studies, this conclusion has to be proved by more studies. © 2013 Editorial Board of Chin J Evid-based Med.

BACKGROUND: Evidence-based practice (EBP) has been proposed as a core competence to improve healthcare quality. The profile of EBP among respiratory therapists (RTs) has not been explored. We investigated how RTs in Taiwan perceive the implementation of EBP. METHODS: We surveyed RTs in Taiwan's regional hospitals during a 4-month period in 2011. RESULTS: A majority of RTs were aware of EBP (88.0%). Although most RTs held a favorable impression of EBP, their knowledge of and skill in EBP implementation were deficient. Only half of the RTs had implemented EBP. Insufficient convenient kits (59.1%), deficient designated personnel (50.0%), and lack of time (45.5%) were major barriers to implementing EBP. RTs rated MEDLINE as the most commonly used evidence-based retrieval database, followed by UpToDate, the Cochrane Library, MD Consult, ProQuest, CINAHL, DynaMed, and Micromedex. Multivariate regression analyses demonstrated sufficient skill in EBP and use of online databases as favorable factors for implementing EBP. In contrast, barriers of time constraint and insufficient knowledge were unfavorable factors for the implementation of EBP. CONCLUSIONS: EBP is not widespread among RTs in Taiwan. We have identified important factors in the implementation of EBP. The data provide valuable evidence for plotting strategies for disseminating EBP implementation. © 2014 Daedalus Enterprises.
