Objective:To explore the effect of quality control circle ( QQC) on the error control in PIVAS. Methods:QQC group was established in the department of PIVAS to reduce the errors in intravenous admixture practice. The status was analyzed using the total errors per week as the index, and the improvement target value was calculated by the eighty-twenty rule. The concrete causes for the errors were found out by the method of“brain storm”, and the main causes were confirmed using a fishbone diagram and the eighty-twenty rule, and then some countermeasures were summarized and carried out. The application effect of QQC was judged by the intan-gible and tangible outcomes before and after the activity, and some suggestions for the further improvement were provided. Results:Af-ter the implementation of QQC activity, the number of errors was reduced from 47 per week to 22 per week with the rate of target a-chievement of 104. 1% and the progress rate of 53. 2%. Moreover, QQC showed positive influence on the sense of being masters, co-operation ability, team spirit and sense of responsibility and confidence in the whole staff, and the ability of analyzing, summarizing and solving problems was also enhanced. Conclusion: QQC can significantly reduce the errors in the practice of intravenous admix-ture. The management method is valuable to explore and analyze the deep problems encountered in PIVAS in order to make rational and efficient measures. It is also helpful to improving the service conception of pharmacists and nurses, and enhancing the roles of pharma-cists in quality management and control to ensure medication safety.

The detection wavelength and the column temperature was 203 nm and 40 ℃,respectively. Results:The spots in TLC were clear without any interference. The linear range of ginsenoside was 38. 9- 194. 5 μg·ml -1(r = 0. 999 3). The average recovery was 98. 3% and RSD was 1. 9%(n = 6). Conclusion:The method is simple and highly specific with good repeatability,which can be used as the quality control method for Shenyan Ⅱ granules.

Objective:To establish the quality standard for Shule capsules. Methods: The microscopic characteristic identifica-tion of Figwort and Radix bupleuri was performed under a microscope. The qualitative identification of fritillary, andrographispaniculata and polygonumbistorta was studied by TLC. The content of salvianolic acid B in Salvia miltiorrhiza was determined by HPLC. The chro-matographic separation was carried out by using a phenomenex synergi 4 hydro-RP 80A (250 mm × 4. 6 mm) column. The mobile phase consisted of acetonitrile-methanol-formic acid-water(10 :30 :59 :1)with gradient elution at a flow rate of 1. 0 ml·min-1, and the injection volume was 10 μl . The detection wavelength and the column temperature was 286 nm and 20 ℃, respectively. Results:The microscopic characteristics were obvious. The spots in TLC were clear without any interference. The linear range was 10. 001-100. 007 μg·ml-1(r=1. 0000). The average recovery was 99. 3% with RSD of 1. 8% (n=6). Conclusion:The method is simple with high specificity and good repeatability, which can be used as the quality control method for Shule capsules.

Objective:To establish an LC-MS/MS method for the content determination of triptolide in Shenshe ointment.Methods:The chromatographic separation was performed on an Agilent TC-C18 (250 mm×4.6 mm,5 μm)column with the mobile phase consisting of methanol-0.1% formic acid solution (73∶27,v/v).The flow rate was 0.5 ml·min-1 and the column temperature was maintained at 35℃.An electrospray ionization (ESI) source was applied with multiple reaction monitoring (MRM) combined with a positive mode.Metronidazole was used as the internal standard.The mass transitions were 361.4→43.2 for triptolide and 172.1→128.0 for metronidazole,respectively.Results:The linear range was 10-500 ng·ml-1 with good correlation coefficient (r=0.999 9).The limit of quantification (LOQ) was 9.5 ng·ml-1.The intra-and inter-day RSDs of peak areas were all less than 3% and the average recovery was 96.87%(RSD=2.79,n=6).Conclusion:The established LC-MS/MS method is simple,efficient,sensitive and accurate in the quality control of Shenshe ointment.

On-the-spot teaching method is one of teaching methods reflecting the principle of linking theory with practice, which is more and more widely used in the professional courses teaching in modern universities and colleges. Through the practice of on-the-spot teaching, students are able to more deeply understand the significance of Management of Military Medicinal Materials Supply so as to improve students' perceptual experience, stimulate their enthusiasm and initiative of learning and make up for the lack of experimental facilities to a certain extent.
