ObjectiveTo probe into the writing quality and rational use of drugs for Emergency Department prescriptions in West China Hospital of Sichuan University. MethodsFrom January 2012 to December 2013, the prescriptions for emergencies were selected randomly. According to prescription management method and standard management of hospital prescription comment requirement, the quality of prescription was analyzed. ResultsFrom 2012 to 2013, the qualified prescription rate increased from 91.45% to 96.70%. The average number of drugs on each prescription was 1 or 2; the utilization rate of antibacterials was below 20.00%; the utilization rate of essential drugs increased from 60.68% to 66.15%; the utilization rate of generic drug name approached 100.00%. However, the utilization rate of injections increased from 82.92% to 85.67%. ConclusionBy prescription reviews, we have listed the problems, and intervened irrational prescription to improve the rate of qualified prescriptions. The high rate of injection utilization is a warning for us to take more effective, more specific and stricter intervention measures.
ObjectiveTo evaluate anti-platelet effect of clopidogrel influenced by CYP2C19*17 polymorphism in patients with cardiovascular disease. MethodsWe electronically searched EMbase, PubMed, The Cochrane Library, ClinicalTrials.gov, CNKI, CBM, WanFang Data and VIP databases for cohort studies about the anti-platelet effect of clopidogrel influenced by CYP2C19*17 polymorphism in patients with cardiovascular disease from inception to October 2012. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed using the software Rev-Man 5.2. ResultsA total of seven studies involving 12 116 patients were finally included. Three were 5 579 CYP2C19*17 carriers and 6 538 non-carriers. The results of meta-analyses showed that, compared with the CYP2C19*17 non-carriers, lower rate of cardiovascular events (OR=0.85, 95%CI 0.73 to 0.99, P=0.03) and higher bleeding events (OR=1.25, 95%CI 1.05 to 1.50, P=0.01) were found in the CYP2C19*17 carriers. ConclusionCYP2C19*17 carriers is with lower cardiovascular events and higher bleeding events than the CYP2C19*17 non-carriers.
Objective To summarize the clinical and pathological manifestation, therapy, and prognosis of primary thyroid lymphoma(PTL). Methods The clinical and pathological data of 20 patients with PTL treated in our hospital from Jan.2002 to Feb.2014 were retrospectively analyzed. Results Of the 20 patients, 14 patients were female, 6 patients were male. The median age were 63.5 years old (45-77 years old). Seven patients (35.0%) were diffused large B-cell lymphoma (DLBCL), and 12 patients (60.0%) were extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma, 1 patient (5.0%) was follicular lymphoma (FL). Twelve patients complicated with Hashimoto thyroiditis. Six patients(30.0%) accepted surgery only, 13 patients(65.0%) were supplemented with chemotherapy and (or) radiotherapy, 1 patient (5.0%) accepted chemotherapy and radiotherapy only. Two patients lost during follow-up, but 18 patients were followed-up for 6-104 months with the median time of 46.5 months. During the follow-up period, 6 patients died of PTL. The cumulative survival rates of 2-year and 5-year were 74.4% and 66.9%, respectively. Conclusion Most PTL are B-cell original non-Hodgkin lymphoma. In order to get good prognosis, chemotherapy and (or) radiotherapy are mostly needed, while surgery is performed for definitive pathological diagnosis.
