Objective To establish a method for quality control of Astragalus Radix and Scutellariae Radix in Biqiaotong granules and provide basis for the establishment of quality standard. Methods The single-factor test method was used to investigate the factors of thin layer chromatography (TLC) conditions, including different extract method and solvents, developing system, comogemc agents, temperature, humidity, drawing amounts and thin layer boards, and to screen the best TLC conditions of Astragalus Radix and Scutellariae Radix . Results The TLC conditions of Astragalus Radix were used trichloromethane-methanel-water (13:7:2) as developing solvent, separated on silica gel G, heatd under 105℃ until the spots bacame clear. The TLC conditions of Scutellariae Radix were used methylbenzene-ethy acetate- formic acid-methanel (9:3:2:2) as developing solvent, separated on silica gel G, observed after 30 minutes under daylight until the spots were clear. Conclusions The spot features are clear, and with good separating degree, strong specificity, and good repeatability without the inference of negative control. The TLC method is simple, sensitive and accurate, which can be adopted for the quality control of Biqiaotong granules.
Objective To analyze the causes of drug dispensing errors and reduce the error rate through scientific precautions, and improve the quality of pharmaceutical service. Methods According to the PDCA cycle, existing problems were found in dispensing between January and June 2013, and the causes were analyzed. Then, from July 2013, strategies were developed to decrease the dispensing error rate. The variation trend of dispensing error rate from January 2013 to June 2017 were observed. Result The dispensing error rate decreased since the beginning of PDCA cycle, from 0.042‰ (the first quarter of 2013) to 0.003‰ (the second quarter of 2017). Conclusion The PDCA cycle is an effective intervention to detect the errors during drug delivery in inpatient pharmacy, which could improve the quality of pharmaceutical service and insure the patients’ safety.
目的 评价参附注射液治疗老年人心力衰竭疗效和安全性。 方法 计算机检索Cochrane图书馆，Medline（1950年－2013年10月），Embase（1980年－2013年10月），中国知网（1979年1月－2013年10月）、万方（1986年1月－2013年10月）、维普（1989年1月－2013年10月）数据库，全面收集参附注射液联用西药常规治疗（试验组）与西药常规治疗疗效（对照组）比较的随机对照试验（RCT），分别由2名研究者根据纳入与排除标准，独立筛选文献、提取资料并评价文献质量，采用Revman 5.1软件进行Meta分析。 结果 共纳入8个研究559例患者，研究质量均为C级。Meta分析结果显示：与对照组比较，试验组临床疗效明显提高、症状改善[RR=1.20，95%CI（1.11，1.29），P＜0.000 01]，左室舒张末期内径减小明显[MD=5.90，95%CI（3.97，7.84），P＜0.000 01]、6 min步行试验距离增加[MD=62.48，95%CI（43.12，81.84），P＜0.000 01]，但左室射血分数两组差异无统计学意义[MD=4.79，95%CI（－0.07，9.65），P=0.05]。 结论 参附注射液与西药常规治疗联用能进一步提高老年心力衰竭患者的临床疗效，且安全性较好。
We reported one case of MTX-induced aplastic anemia and reviewed related literature to investigate the mechanism of action of MTX, and summarize the clinical feature, diagnostic criteria, risk factor, and interventions. These were hoped to arouse the attention of clinicians and clinical pharmacists, in order to effectively prevent, diagnose, and treat MTX-induced aplastic anemia.
目的 分析四川大学华西医院麻醉性镇痛药应用的现状及趋势，并行客观评价。 方法 对2008年－2010年四川大学华西医院麻醉性镇痛药品的种类、用量、金额、用药频度等进行归类统计、比较和分析。 结果 住院部使用麻醉药品的用量及金额呈上升趋势。临床应用以芬太尼类居首。新型麻醉药品的应用也有上升趋势。 结论 麻醉性镇痛药的应用基本合理，但创建无痛医院仍需进一步完善，并提交合理用药水平。
