[Improving comprehensive retention rate of peppermint oil in freeze-dried preparation based on cyclodextrin inclusion technology].

The freeze-drying technique, characterized by low-temperature processing, is especially suitable for sensitive volatile oils with thermal instability. However, there are few studies focusing on the retention of volatile oils in the processing of freeze-dried preparations. This study evaluated the effects of different addition methods(adsorption, emulsification, solid dispersion, and inclusion) on the retention rate of the main components in peppermint oil, aiming to explore the application feasibility of freeze-dried preparations of volatile oils.

[Molecular mechanism of Qishen Yiqi Dripping Pills in treating myocardial ischemia:a study based on HIF-1 signaling pathway].

Qishen Yiqi Dripping Pills(QSYQ) are used clinically to treat various myocardial ischemic diseases, such as angina pectoris, myocardial infarction, and heart failure; however, the molecular mechanism of QSYQ remains unclear, and the scientific connotation of traditional Chinese medicine(TCM) compatibility has not been systematically explained. The present study attempted to screen the critical pathway of QSYQ in the treatment of myocardial ischemia by network pharmacology and verify the therapeutic efficacy with the oxygen-glucose deprivation(OGD) model, in order to reveal the molecular mechanism of QSYQ based on the critical pathway. The key targets of QSYQ were determined by active ingredient identification and target prediction, and underwent pathway enrichment analysis and functional annotation with David database to reveal the biological role and the critical pathway of QSYQ.

[Inhibitory effect of wogonin on human colorectal cancer cell SW480 based on network pharmacology].

Wogonin is a main effective component of Scutellaria baicalensis, with a significant anti-cancer activity. Recently, extensive studies focused on anti-cancer pharmacological effects of wogonin, but there were still a few studies on its molecular mechanism. Therefore, the molecular targets of its anti-cancer activity were still unclear.

[Formation and development of Dao-di herbs "Long" medicines].

Gansu province,which spans the Yangtze river,is in the upper reaches of the Yellow river and located at the intersection of the Qinghai-Tibet plateau,the Inner Mongolia plateau and the Loess plateau. All of these areas are highly respected by doctors of all ages as they have enriched the resources of traditional Chinese medicines. In the interaction between the heavens and the earth,the interaction between the people and the future has been passed down to the present.

[Research on attributes of biopharmaceutics classification system for Chinese materia medica of baicalein in Gegen Qinlian Decoction environment].

For the effects of multi-component environment on the solubility and permeability of single components,and the problems of biopharmaceutical attribute classification of single components in the compound prescriptions environment,baicalein was used as the research object in this study to investigate the biopharmaceutic attributes of single-component and their traditional Chinese medicine( TCM) biopharmaceutic attributes in the multi-component environment of Gegen Qilian Decoction. Shaking flask method,intrinsic dissolution rate test and HPLC were used to determine solubility of baicalein. Markers specified by FDA were utilized as permeable boundary reference materials to verify the applicability of the single-pass intestinal perfusion method( SPIP),and the quantitative research on the permeability of baicalein was also conducted.
