What drug dosage range is appropriate for treatment? What drug dosage range can maximally reduce the incidence of adverse drug reaction (ADR)? The gold zone method as a new method of evidence-based medical research was proposed to study those two blind areas of drug dosage in this article. Studying the dose-effect relationship, taking gold zone as the middle range and dividing empirical range into 3 sections were the key to study design. The evidence-based survey with extremely large sample showed a U-shaped rule existing between the antibiotics’ dosage and the incidence of ADR; and the dosage in gold zone appeared at the bottom of U-shaped curve. The gold zone method for determining dosage is a special breakthrough currently for solving those two blind areas of drug dosage
This article introduced search methods for adverse effects of healthcare interventions in MEDLINE, EMBASE and CBM (Chinese Biomedical Literature Database). The search strategies included the selection of publication type and the determination of medical subject headings and keywords both in English and Chinese, which will help identify relevant reports.
【摘要】 目的 探讨研究静脉滴注丹参注射液发生不良反应的类型及因素,为临床用药提供依据。 方法 对2007年1月-2010年12月82例因静脉滴注丹参注射液发生不良反应的患者资料进行回顾分析,并对其相关因素进行分析。 结果 男性的不良发生率高于女性,不良反应发生年龄多为中、老年患者,并且不良反应多发生在输液30 min内,多为Ⅰ型过敏反应。 结论 对丹参注射液应严格控制生产工艺流程,临床用药要掌握适应证,以避免不良反应的发生。【Abstract】 Objective To investigate the types and factors of adverse reactions caused by intravenous infusion of Danshen injection, in order to provide basis for clinical drug application. Methods We retrospectively analyzed the clinical records of 82 patients with adverse reaction to intravenous infusion of Danshen injection from January 2007 to December 2010. Results Adverse reaction incidence was higher in males than females, and it mainly occurred in patients of middle or old ages. Most of the adverse reactions happened within 30 minutes of the infusion. Type-I allergic reaction was more commonly observed. Conclusion In order to avoid the occurrence of adverse reactions, Danshen injection production process should be strictly controlled, and indications should be considered carefully in clinical medication.
【摘要】 目的 评价舒林酸治疗结直肠息肉的有效性和安全性。 方法 计算机检索PubMed、Cochrane Iibrary、Embase、SCI、CNKI、万方、维普、CBM数据库。按Cochrane系统评价的方法评价纳入研究质量,并进行Meta分析。 结果 共纳入7个随机对照试验(RCT),共235例患者。Meta分析结果显示舒林酸治疗腺瘤性息肉病(FAP)在有效率、息肉消失率方面与安慰剂比较,差异无统计学意义(Pgt;0.05);治疗散发性结肠腺瘤性息肉病(SCAP)在有效率、息肉消失率、腺瘤直径变化方面与安慰剂比较,差异有统计学意义(Plt;0.05);舒林酸的不良反应多为消化道症状,与安慰剂比较差异有统计学意义(Plt;0.05)。 结论 系统评价结果显示舒林酸对于家族性FAP的疗效尚不确切,而对SCAP有一定的疗效。【关键词】结直肠息肉;舒林酸;有效性;不良反应;系统评价【Abstract】 Objective To assess the efficacy and safety of sulindac on colorectal polyps. Methods The literatures were searched from several databases including PubMed,Cochrane Iibrary,SCI,CNKI,Wanfang,VIP,and CBM. The quality of the researches was evaluated according to Cochrane systematic reviews, and the Meta analysis was performed. Results Seven RCT were enrolled with a total of 235 patients. Meta analysis showed that there was no significant difference in the effective rate and polyps disappearance rate of FAP between the two groups (Pgt;0.05). There were significant differences in the effective rate, polyps disappearance rate and size of adenomas between the two groups (Plt;0.05); the most common adverse event was the symptoms of digestive tract which differed much from that in the placebo group (Plt;0.05). Conclusion The therapeutic effect of sulindac on FAP is not sure, but it is effective on SCAP.
