ABSTRACT
Panax notoginseng is an ancient Chinese medicinal plant that has great clinical value in regulating cardiovascular disease in China. As a single component of panax notoginosides, notoginsenoside R1 (NGR1) belongs to the panaxatriol group. Many reports have demonstrated that NGR1 exerts multiple pharmacological effects in ischemic stroke, myocardial infarction, acute renal injury, and intestinal injury. Here, we outline the available reports on the pharmacological effects of NGR1 in ischemia-reperfusion (I/R) injury. We also discuss the chemistry, composition and molecular mechanism underlying the anti-I/R injury effects of NGR1. NGR1 had significant effects on reducing cerebral infarct size and neurological deficits in cerebral I/R injury, ameliorating the impaired mitochondrial morphology in myocardial I/R injury, decreasing kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin in renal I/R injury and attenuating jejunal mucosal epithelium injury in intestinal I/R injury. The various organ anti-I/R injury effects of NGR1 are mainly through the suppression of oxidative stress, apoptosis, inflammation, endoplasmic reticulum stress and promotion of angiogenesis and neurogenesis. These findings provide a reference basis for future research of NGR1 on I/R injury.

ObjectiveTo explore the mechanism of hypericin against liver cancer using network pharmacology. MethodThe traditional Chinese medicine systems pharmacology database and analysis platform （TCMSP）， Drug Gene Interaction Database （DGIdb）， Comparative Toxicogenomics Database （CTD） and SwissTargetPrediction were used to predict the targets of hypericin. Five databases including GeneCards and Online Mendelian Inheritance in Man （OMIM） were employed to obtain liver cancer-related targets. The intersection was performed to obtain the targets of hypericin against liver cancer. The Database for Annotation， Visualization and Integrated Discovery （DAVID） v2021q4 was used for Gene Ontology （GO） function annotation and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis. The protein-protein interaction （PPI） network of the targets was constructed by Cytoscape 3.6.1 to screen the core targets，and the affinity between hypericin and the core targets was verified by molecular docking. The effects of hypericin on liver cancer and the migration of liver cancer cells were observed by cell viability assay and would healing assay， respectively， and its effects on the mRNA and protein expression of key targets cysteinyl aspartate-specific protease-3（Caspase-3） and mitogen-activated protein kinase 3 （MAPK3） were detected by real-time polymerase chain reaction（Real-time PCR） and Western blot， respectively. ResultA total of 45 genes related to the anti-liver cancer effect of hypericin were obtained， and six core target genes were screened. The signal pathways enriched by KEGG pathway analysis included apoptosis，tumor necrosis factor （TNF） and cancer signal pathways. Molecular docking showed that the core target genes Caspase-3，TNF，estrogen receptor 1 （ESR1），MAPK3，catalase （CAT） and cyclooxygenase 2 （PTGS2） had good affinity with hypericin，especially Caspase-3 and MAPK3. In addition，compared with the conditions in control group， cell experiments demonstrated that hypericin could reduce the viability of liver cancer cells （P<0.05），inhibit their migration，increase the mRNA expression of Caspase-3 （P<0.05） and decrease that of MAPK3 （P<0.05）. ConclusionHypericin exerted the anti-liver cancer effect by affecting the core targets such as Caspase-3，TNF，ESR1，MAPK3，CAT and PTGS2 and jointly interfering with apoptosis，TNF and cancer signal pathways.
ABSTRACT
Ranae Oviductus has a good tonic effect and is commonly used for both medicine and food. The use of Ranae Oviductus was confused because the origin of Ranae Oviductus was roughly recorded in ancient herbal literatures. In order to clarify the confusing literatures and trace the origin of Ranae Oviductus，this paper conducted a textual research on the name，origin，distribution，harvesting and processing，efficacy of the Chinese medicine by consulting ancient herbal books，modern literatures and monographs of traditional Chinese medicine. The results of the textual research showed that Ranae Oviductus belongs to Manchu medicine，which was first applied by the Manchu people because of its tonic effect. The original animal of Ranae Oviductus has many names，which are all translated from Manchu language. By analyzing the descriptions of Ranidae in various herbal books，it is concluded that the earliest description of the original animals of Ranae Oviductus appeared in the Shengjing Tongzhi compiled by Agui in the Qing dynasty. After summarization of the taxonomic changes of some species of Rana，the original animals of Ranae Oviductus were preliminarily determined as Rana dybowskii，R. amurensis and R. huanrenensis. We excluded R. huanrenensis by its size and R. amurensis by its poor quality. Therefore，the original animal of Ranae Oviductus is R. dybowskii，the main production area is northeast China and the best capture time is in October. Ranae Oviductus is often eaten after being stewed. The study can provide the effective basis for the identification of the original animal of Ranae Oviductus，the distribution of production area and the utilization of resources.

ABSTRACT
Excavating and characterizing the dosage forms characteristics of classic Chinese medicine preparations is the basis for the innovation of modern preparations of Chinese medicine. Through the combing statistics of the National Natural Science Foundation of China (NSFC) on the establishment of traditional Chinese medicine preparations, the research literature on Chinese medicine preparations at home and abroad, and the registration of new Chinese medicines in the past ten years, this paper finds that the research projects of classic Chinese medicines have been greatly reduced. The market share of traditional Chinese medicine classics has shrunk year by year. The modern preparation produced in the "preparation of traditional Chinese medicine by western medicine technology" mode dominates the market. However, because of its "degraded" effect, it is less competitive. Therefore, with the wave of classic dosage forms research promoted by national policies, accelerating the study of classical Chinese medicine preparations will not only promote the development of pharmaceutical discipline of traditional Chinese medicine, enhance the classic medical culture literacy, but also promote the protection and inheritance of classic medicine.
ABSTRACT
The central nervous system (CNS) plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain. In healthy subjects, blood glucose is normally maintained within a relatively narrow range. Hypoglycemia in diabetic patients can increase the risk of complications, such as heart disease and diabetic peripheral neuropathy. The clinical research finds that the use of traditional Chinese medicine (TCM) has a positive effect on the treatment of hypoglycemia. Here the authors reviewed the current understanding of sensing and counterregulatory responses to hypoglycemia, and discuss combining traditional Chinese and Western medicine and the theory of iatrogenic hypoglycemia in diabetes treatment. Furthermore, the authors clarify the feasibility of treating hypoglycemia on the basis of TCM theory and CNS and have an insight on its clinical practice.
