A New Strategy in Drug Design of Chinese Medicine:Theory,Method and Techniques

引用

Chinese Journal of Integrative Medicine 2012年第11期18卷 803-806页

作者：杨洪军申丹许海玉卢鹏 Institute of Chinese Materia Medica China Academy of Chinese Medical Sciences Beijing (100700) China Institute of Automation Chinese Academy of Sciences Beijing (100290) China

The research and development （R＆D） process of Chinese medicine, with one notable feature, clinical application based, is significantly different from which of chemical and biological medicine, from laboratory research to clinics. Besides, compound prescription is another character. Therefore, according to different R＆D theories between Chinese and Western medicine, we put forward a new strategy in drug design of Chinese medicine, which focuses on ＂combination- activity relationship （CAR）＂, taking prescription discovery, component identification and formula optimization as three key points to identify the drugs of high efficacy and low toxicity. The method of drug design of Chinese medicine includes： new prescription discovery based on clinical data and literature information, component identification based on computing and experimental research, as well as formula optimization based on system modeling. This paper puts forward the concept,research framework and techniques of drug design of Chinese medicine, which embodies the R＆D model of Chinese medicine, hoping to support the drug design of Chinese medicine theoretically and technologically.

Application of Uniform Design and SVR for Culture Medium optimization of Organophosphorus Degradation Bacteria

引用

Agricultural Science & Technology 2018年第6期19卷 43-47页

作者： TAN Xian-sheng ZHU Xiong-mei ZHOU Yu-liang LI Wei-wei LIU Li-na HU Jun-he JIN Chen-zhong LI Wen-juan Farmland Weed Prevention and Control Technology and Application-innovation Center of Hunan Province Hunan Institute ofHumanities Science and Technology Pesticide Harmless Application Key Laboratory of Provincial College Loudi 417000 PRC College of Agriculture and Biotechnology Hunan University of Humanities Science and Technology Loudi 417000 PRC

In order to improve the degradation activity of organophosphorus degradation bacterial strains, uniform design and support vector regression(SVR) are used to optimize the formula of mineral salt medium for the strains based on single factor experiment. The formula being used after SVR optimization is glucose 1.24 g/L,NH4 NO3 0.73 g, KH2 PO4 0.96 g, KCl 0.50 g, MgSO4·7 H2 O 0.50 g, MnSO4 0.02 g, CaCl2 0.04 g, distilled water 1 000 mL;the highest degradation rate is obtained at pH7.0(SVR, 76.68%), superior to that of the QSAR model(74.67%). The formula optimization method based on uniform design and SVR is very promising to apply in various multiple-factor and multiple-level formula optimization experiments.

Study on Preservative formula and Shelf Life of Cantonese Style Moon Cakes

Agricultural Science & Technology 2017年第11期18卷 2171-2174页

To ensure the safety of consumers, prolong the shelf life of moon cake and reduce the cost of manufacturing and marketing enterprises, the optimization of preservative formula and the shelf life of cantonese style moon cake were studied. Through single and compound formula preservative test, the results showed that potassium sorbate and sodium dehydroacetate could inhibit the microorganisms in the moon cake, but the inhibitory effect of sodium dehydroacetate was stronger than that of potassium sorbate; and the combination of potassium sorbate and sodium dehydroacetate had a synergistic effect, and the best formula is ＇potassium sorbate 0.44 g/kg mixed with sodium dehydroacetate 0.38 g/kg. A batch of moon cake was prepared with the best preservative formula, then the total number of colonies, molds and coliform group in the samples were detected by random sampling at irregular intervals. The total number of molds exceeded the limit on the 187^th d, and it indicated that the shelf life of the product was 187 d. Compared with the conventional 15-day shelf life, this research greatly prolongs the sheff life of cantonese style moon cake, and cut down the cost of moon cake enterprises. It is worthy of popularization and application.
