[Discussion on historical evolution and modern research progress of Sesami Semen Nigrum processing based on visual thinking].

Sesami Semen Nigrum has a long history of dual use(medicine and food). The research of its processing technology is related to the development and utilization of its own "medicine-food balance" feature, which is the basis for Sesami Semen Nigrum to realize the modernization of technology and standardization of quality. Due to its various processing methods and the long history span, the traditional medical classics(from the end of Han Dynasty to the Republic of China), modern standard specification and researches on processing were sorted out with the help of database and document mining technology, and the visual thinking was adopted to analyze the evolution trend of Sesami Semen Nigrum processing methods. In addition, the processing characteristics of Sesami Semen Nigrum in various periods and effect of processing on its chemical compositions and pharmacological effect were briefly described to explore the differences and their reasons in the processing of Sesami Semen Nigrum from ancient times to the present time, aiming to provide an idea and documentary basis for the study of traditional processing technology.

Transformation and attribution of drug properties in Galla Chinesis fermented Baiyaojian based on cold and heat syndrome rats / 中国中药杂志

To reveal the transformation and attribution of drug properties in Galla Chinesis fermented Baiyaojian by studying the effect of Galla Chinesis and Baiyaojian on cold and heat syndrome rats. Euthyrox was used to induce the hyperthyrosis model,ice water stimulation was used to induce the cold syndrome model,and different concentrations of Galla Chinesis and Baiyaojian water decoction were administrated by gavage for 15 d continuously. Symptom indexes were evaluated,content of pyruvic acid( PA),ATPase activity in liver and contents of DA,T4,cAMP,5-HT,NE,17-OHCS,TRH and TSH in serum were assayed by enzyme linked immunosorbent assay and spectrophotometry. The rectal temperature,water consumption and body weight of heat syndrome rats in model group were increased,cAMP,NE,17-OHCS,TRH and PA were increased,TSH,Na-K ATPase and Ca-Mg ATPase were increased significantly( P<0. 01),while 5-HT was decreased,compared with those of the blank group( P< 0. 05),the contents of T4,DA,NE,TSH,TRH,cAMP and 17-OHCS were decreased significantly( P<0. 01),PA and Ca-Mg ATPase in WG and BG groups were decreased compared with those of the model group( P<0. 05),and the Galla Chinesis content of WG group was lower than that of BG group,while the contents of 5-HT in WG and BG groups were increased,and the Galla Chinesis content of WG group was higher than that of BG group,with no significant difference of viscera index between heat syndrome rats in blank group,model group and drug groups. The rectal temperature,water consumption and body weight of cold syndrome rats in model group were decreased,DA,T4,cAMP,NE,17-OHCS,TRH,TSH,PA,Na-K ATPase and Ca-Mg ATPase of rats in model group were decreased,whereas 5-HT was increased compared with those of the blank group( P<0. 05),the indexes of heart,lung and kidney were significantly higher than those in the blank group( P<0. 05). Both Galla Chinesis and Baiyaojian can significantly alleviate the symptoms of heat syndrome rats caused by levothyroxine sodium. Galla Chinesis has a better effect than Baiyaojian,but cannot alleviate the symptoms of cold syndrome caused by ice water stimulation,suggestting that the decoction of Galla Chinesis and Baiyaojian are both cold,but Galla Chinesis is colder than Baiyaojian. Cold property in Galla Chinesis fermented Baiyaojian can be relieved. In clinical application,the property of " slight cold" is more accurate than " neutral property" for Baiyaojian.
