Regularity of traditional Chinese medicine prescriptions for same treatment for cardiovascular and cerebrovascular diseases / 中国中药杂志

To explore the regularity of traditional Chinese medicine(TCM) prescriptions for cardio-cerebrovascular diseases,the core drug groups with common therapeutic effects on cerebrovascular diseases represented by stroke and cardiovascular diseases represented by coronary artery disease were extracted,and their consistency and difference in the treatment of different diseases were analyzed.A total of 388 Chinese patent medicines were collected for the treatment of cerebrovascular diseases,cardiovascular diseases and cardio-cerebrovascular diseases.The dominant and recessive patterns of Chinese patent medicines in clinical use were found by "frequency analysis","compatibility analysis" and "network analysis" respectively.According to the findings of the three parts,Salviae Miltiorrhizae Radix et Rhizoma,Chuanxiong Rhizoma,Carthami Flos and Astragali Radix have a high frequency of use in the treatment of brain disease,heart disease and both,with frequent combined medication.Data mining confirmed the core drug combinations for the treatment of cerebral and cardiac vascular diseases,so as to reveal the similarities and differences in the drug use of Chinese medicine for these diseases,and provide a basis for the rational use of traditional Chinese medicine in clinical practice.This analysis also defines a new direction for the future development of prescription combinations for different indications of cerebral and cardiac diseases.

New evidence supporting “intermittent pulse and severe palpitation” theory for prevention and treatment of complications of atrial fibrillation and heart failure / 中草药

The latest international clinical results show that heart failure and atrial fibrillation are two common heart diseases with extremely high coincidence. However, the existing therapeutic drugs and methods are all aimed at a single target of their respective diseases, ignoring the complex factors of complications. It is hopeful to find effective therapeutic drugs for arrhythmia and complications of heart failure from combination drugs, especially natural Chinese herbal medicines, based on the perspective of Chinese medicine. This article started with the existing clinical medicine and treatment methods for heart failure and arrhythmia, combed the traditional Chinese medicine prescriptions and single herb medicines for treating these two diseases, in which prepared licorice decoction and its derived modern Chinese medicines Wenxin Granule were systematically explored. The common targets of heart failure and arrhythmia and the prediction of the target of Wenxin Granule in the previous period were analyzed by network pharmacology, it was suggested that “intermittent pulse and severe palpitation” may be the comprehensive clinical manifestations of arrhythmia and heart failure. This article traced the origin and interpretation of the scientific connotation of “intermittent pulse and severe palpitation”.

Simultaneous determination of 4 diterpenoids in Rabdosia japonica var.glaucocalyx by HPLC-ESI-MS/MS and cluster analysis / 中国中药杂志

A quick HPLC-ESI-MS/MS method was established for simultaneous determination of four major diterpenoids in Rabdosia japonica var.glaucocalyx, including glaucocalyxin A, oridonin, hebeirubesensin and enmenol. Analysis was performed on an Agilent ZORBAX SB-C18(4.6 mm×250 mm, 5 μm ) column eluted in a gradient program with methanol and water. The flow rate was 0.8 mL•min⁻¹. Multiple reaction monitoring (MRM) scanning mode was performed in negative ion switching mode to apply for the quantitative determination. The calibration curves for the above four compounds were linear in corresponding injection amount. The average recoveries of the compounds ranged from 92.40% to 105.9%, with RSDs of 1.7%-6.5%. The method is simple, rapid, accurate with good repeatability, which can provide a reference for overcalling evaluation the quality of R. japonica var.glaucocalyx. The result of cluster analysis- showed that the quality of R. japonica glaucocalyx var. greatly varied between areas and parts.

Simultaneous determination of 3 phenolic acids in Usnea by HPLC-ESI-MS/MS / 中国中药杂志

A quick HPLC-ESI-MS/MS method was established for simultaneous determination of three chemical compositions in Usnea, including usnic acid, diffractaic acid, and ramalic acid. The separation was performed on a chromatographic column of Agilent ZORBAX SB-C, (4.6 mm x 250 mm, 5 µm), and the mobile phase was methanol (0.05% formic acid)-0.05% formic acid solution (4 mmol ammonium acetate), with an isocratic elution at a flow rate of 0.8 ml · min⁻¹. Multiple reaction monitoring scanning mode (MRM) was performed combined with the ion switching technology in positive and negative ion switching mode to apply for the quantitative determination. The calibration curves for the above three compounds were linear in corresponding injection amount. Their average recoveries were 95.0%-105.1%, with RSDs of 1.1%-5.2%. The method was simple, rapid, accurate with high repeatability, which could provide a reference for overcalling evaluation the quality of Usnea.
