OBJECTIVE:To study the potential targets of Guizhi decoction regulating Ying and Wei based oncorrespondence between formulation and syndromerelationship and reverse molecular docking technology. METHODS:Active ingredients related to Guizhi decoction were obtained by literature retrievals,and PharmMapper Server was used for reverse molecular docking for ac-tive ingredients. The potential receptors of Guizhi decoction were found on the basis of docking scores,then AutoDock Vina was conducted for positive molecular docking test to observe the affinity between the ligand and the receptor molecule. 75 rats were ran-domly divided into normal group,model group,Guizhi decoction high-dose,medium-dose,low-dose groups(12,8,4 g/kg),15 in each group. Except for normal group,rats in other groups were induced for models with disharmony between Ying and Wei. Af-ter modeling,rats were intragastrically administrated once a day,for 5 d. After administration,11β-HSD1 expression levels in adi-pose tissue and muscle tissue of rats were detected. RESULTS:Reverse molecular docking for active ingredients of Guizhi decoc-tion found that 11β-HSD1 was the frequent receptor,and positive docking test confirmed that uralsaponin b,glycyrrhetnic acid and carbenoxolone and so on had higher affinity with 11β-HSD1. Results of animal test showed,compared with normal group,11β-HSD1 expression levels in adipose tissue and muscle tissue in model group were increased (P<0.05);and compared with model group,11β-HSD1 expression levels in adipose tissue and muscle tissue in Guizhi decoction high-dose group were decreased (P<0.05). CONCLUSIONS:Guizhi decoction regulating Ying and Wei has certain correlation with 11β-HSD1,while the reverse molec-ular docking technology can provide a feasible technical way to studycorrespondence between formulation and syndromerelation-ship.

β-carotene has a wide range of application in food, pharmaceutical and cosmetic industries. For microbial production of β-carotene in Saccharomyces cerevisiae, the supply of geranylgeranyl diphosphate (GGPP) was firstly increased in S. cerevisiae BY4742 to obtain strain BY4742-T2 through over-expressing truncated 3-hydroxy-3-methylglutaryl-CoA reductase (tHMGR), which is the major rate-limiting enzyme in the mevalonate (MVA) pathway, and GGPP synthase (GGPS), which is a key enzyme in the diterpenoid synthetic pathway. The β-carotene synthetic genes of Pantoea agglomerans and Xanthophyllomyces dendrorhous were further integrated into strain BY4742-T2 for comparing β-carotene production. Over-expression of tHMGR and GGPS genes led to 26.0-fold increase of β-carotene production. In addition, genes from X. dendrorhous was more efficient than those from P. agglomerans for β-carotene production in S. cerevisiae. Strain BW02 was obtained which produced 1.56 mg/g (dry cell weight) β-carotene, which could be used further for constructing cell factories for β-carotene production.

This study was aimed to reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia based on association rules and clustering of data mining technology. Articles on Chinese patent medicine in the treatment of breast hyperplasia were retrieved from databases. External formulas or those mixed with western drugs were excluded. Terminologies in the selected formulas were standardized. Information was extracted to build excelltables. Association rules analysis and cluster analysis were used to reveal the medication patterns of Chi-nese patent medicine in the treatment of breast hyperplasia with software R2.15.2 and Cytoscape 2.8.3. The results showed that Chinese medicinals with higher frequency in 195 formulas were Radix bupleuri, Rhizoma cyperi, Chinese Angelica, Selfheal, White Peony Root, Trichosanthes kirilowii Maxim et al. Chinese medicinals with lower frequency were Chinese Alangium leaf, Rhinacanthus nasutus et al. The commonly used herbal pairs were Radix bupleuri -Chinese A ngelica, Rhizoma curcumae - Rhizoma sparganii, frankincense - myrrh et al. The strong association rules indicated that Xiaoyaosan, which takes Radix bupleuri and Chinese A ngelica as its core, is the key character of Chinese patent medicine in the treatment of breast hyperplasia. The cluster analysis revealed several Chinese medicine functional modules, such as Fructus forsythiae - Rhizoma smilacis glabrae - Evodia lepta - Chinese mahonia stem - Lignum millettiae et al. It was concluded that the herbal frequency, herbal pairs, strong associa-tion rules and cluster analysis can reveal the medication patterns of Chinese patent medicine in the treatment of breast hyperplasia in order to provide reference evidences in the optimization of clinical treatment for mula and im-provement of therapeutic efficacy.
