Research progress on chemical constituents and pharmacological effects of Kaixin Powder and predictive analysis of its Q-markers / 中国中药杂志

Kaixin Powder is a classic prescription for invigorating Qi, nourishing the mind, and calming the mind. It has pharmacological effects of improving learning and memory ability, resisting oxidation, delaying aging, and promoting the differentiation and regeneration of nerve cells. It is mainly used in the modern clinical treatment of amnesia, depression, dementia, and other diseases. The present paper reviewed the research progress on the chemical composition and pharmacological action of Kaixin Powder, predicted and analyzed its quality markers(Q-markers) according to the concept of Chinese medicine Q-markers, including transmission and traceability, specificity, effectiveness, measurability, and compound compatibility environment. The results suggested that sibiricose A5, sibiricose A6, polygalaxanthone Ⅲ, 3',6-disinapoylsucrose, tenuifoliside A, ginsenoside Rg_1, ginsenoside Re, ginsenoside Rb_1, pachymic acid, β-asarone, and α-asarone could be used as Q-markers of Kaixin Powder. This study is expected to provide a scientific basis for establishing the quality control system and the whole process quality traceability system of Kaixin Powder compound preparations.

Research Progress on G2/M Arrest in Breast Cancer Cells by Active Compounds of Traditional Chinese Medicine / 中国实验方剂学杂志

The global incidence of breast cancer has increased year by year. Breast cancer has the highest mortality rate in female patients with malignant tumors. Traditional Chinese medicine（TCM） has made great contribution to health of human being， improving the overall curative effect， reducing the patients' pain， improving the quality of life and alleviating adverse reactions in patients. TCM and its active compounds can inhibit the proliferation of breast cancer cells by inducing cell cycle arrest， invasion， metastasis and reversing multidrug resistance. The effect of the compounds in TCM is obvious on inducing the arrest of the breast cancer cells cycle. It′s a novel method to fight against breast cancer by influencing the progress of the breast cancer cell cycle and inducing the cell cycle arrest in breast cancer cells. Lots of studies have shown that the G2/M phase checkpoint which transition from gap-phase （G2 phase） to mitotic phase （M phase） in the cell cycle is the key point for cell survival or death. Many antitumor drugs can inhibit the proliferation of tumor cells through the cell cycle arrest. We summarized the domestic and foreign literatures in recent years， and comprehensively explained the research progress on the related regulatory molecules in G2/M arrest. In addition， we summarized and sorted out the researches on the methods and ways of alkaloids， polysaccharides， terpenes， flavonoids， saponins and other active compounds of TCM in inducing the G2/M arrest of human breast cancer cells. By summarizing the active compounds of various Chinese medicines in inducing G2/M arrest of breast cancer cells， and reviewing the research progress on mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells， we will， in this paper， investigate the mechanism of active TCM compounds for inhibiting the proliferation of breast cancer cells through inducing G2/M arrest of human breast cancer cells， so as to provide a scientific basis for in-depth research on the anti-breast cancer mechanism of the active compounds in TCM.

Review of chemical composition, pharmacological effects, and clinical application of Salviae Miltiorrhizae Radix et Rhizoma and prediction of its Q-markers / 中国中药杂志

Salviae Miltiorrhizae Radix et Rhizoma is a Chinese herbal medicine that promotes blood circulation to remove blood stasis, nourishes blood to tranquilize the mind, and cools blood to disperse carbuncles. Salviae Miltiorrhizae Radix et Rhizoma has microcirculation-improving, blood vessel-dilating, atherosclerosis-preventing, anti-inflammatory, anti-tumor, and blood pressure-and blood lipid-lowering activities. As research progresses, the chemical composition, pharmacological effect, and clinical application of Salviae Miltiorrhizae Radix et Rhizoma have attracted much attention. We reviewed the research progress in this field. Based on the concept of quality marker(Q-marker) in traditional Chinese medicine, the Q-markers of Salviae Miltiorrhizae Radix et Rhizoma were predicted and analyzed from the aspects of quality transfer, traceability, ingredient specificity, association between ingredients and pharmacological effects, ingredient predictability, and compounding environment. This review provides a scientific basis for the quality control of Salviae Miltiorrhizae Radix et Rhizoma and its preparations.

Applications of DNA barcoding in Chinese materia medica identification / 中草药

DNA barcoding involves the standardized use of one or a few DNA regions to tell species apart. It represents a hotspot of biological studies and one of the most rapid development directions of biology in recent years. Herein, we reviewed the development and current advances of plant DNA barcoding, focusing on the prospect of ultra-barcode in the identification of closely related species; The applications of DNA barcodes in the identification of traditional Chinese herbal medicine, the identification of genuine medicinal material and medicine traceability system. We also emphasized that the plant DNA barcoding will play an important role in the evaluation, protection and sustainable utilization of traditional Chinese medicine resources. This review may offer a new idea for the proceeding studies of medicinal plant DNA barcoding.
