OBJECTIVE:To make an investigation on the quality of decoctions of traditional Chinese medicine prepared by decocting device and fire heating decocting method.METHODS:To compare the chemical compositions in decoctions of Salvia miltiorrhiza Bunge prepared by above-mentioned two methods and to take the contents of danshensu and protocatechualdehyde as indices,both of which were determined by HPLC.RESULTS:There were no evident difference between the two methods in extracting chemical compositions.In addition,the contents of danshensu and protocatechualdehyde prepared by decocting device were as2.97times and5.6times as those prepared by fire heating decocting method respectively.CONCLUSION:The prepa?ration of decoction of Saliva miltiorrhiza Bunge by decocting device can double the effective constituents.This provides scien?tific basis for making rational use of herbs.

Objective: To establish a method of HPLC for determination of paeoniflorin in Yifu Capsules. Methods: HPLC analysis was carried out on ALLIMA C 18 column with acetonitrile water(15:85) as a mobile phase and detection wavelength at 230nm. Results: The linear range was 0.0798～0.7980?g (?=0.9998,n=6), and the average recovery was 99.00%(RSD=2.17%,n=5). Conclusion: The method is simple, accurate,highly sensitive and reproducible. It can be used for determination of paeoniflorin in Yifu Capsules.

OBJECTIVE:To intensify the scientific inner management of drugs in hospitals,lower the operation cost on drug management and guarantee patients' medication safety.METHODS:The problems occurred in hospital drug management were analyzed,and the method of management by objective and PDCA cyclical method in scientific management were employed to make a target plan in conformity with the three-level drug management model of our hospital and then the management proposal was carried out.RESULTS & CONCLUSIONS:The application of scientific management enhanced hospital drug management level as well as working efficiency,and the quantity of the overdue drugs was lowered by 90.5% in 2008 than in the same period of 2007.

To improve the blast resistance of elite rice restorer line Fuhui 673, 3 blast resistance genes Pi-1, Pi-9 and Pi-kh were introduced into Fuhui 673 from a good-quality restorer line Jinhui 1059 through 3 successive backcrosses followed by one selfing using the technique of marker-assisted selection. Ten near-isogenic lines (NILs) of Fuhui 673 carrying the 3 introduced resistance genes were created. Genotype analysis using 68 SSR markers evenly distributed in the genome indicated that 92.96%-98.59% of the NILs' genetic background had been recovered to Fuhui 673. Both indoor and field resistance tests indicated that the NILs and their hybrids with sterile line Yixiang A were all resistant to rice blast, with resistance levels significantly higher than those of controls Fuhui 673 and hybrid Yiyou 673 (Yixiang A  Fuhui 673). In addition, among the 10 hybrids between the NILs and Yixiang A, 2 showed significantly higher yield than and 4 displayed similar yield to that of control Yiyou 673, suggesting that most of the NILs retained the elite characteristics of Fuhui 673. Two new hybrid rice cultivars Liangyou 7283 and Jintaiyou 683 from NIL Line 9 showed high yield, good resistance to blast and moderate growth period in regional trial, suggesting that the NIL Line 9 has a good prospect for application.
