Chinese herbal injection for cardio-cerebrovascular disease: Overview and challenges.

Cardio-cerebrovascular diseases are the leading cause of death worldwide and there is currently no optimal treatment plan. Chinese herbal medicine injection (CHI) is obtained by combining traditional Chinese medicine (TCM) theory and modern production technology. It retains some characteristics of TCM while adding injection characteristics. CHI has played an important role in the treatment of critical diseases, especially cardio-cerebrovascular diseases, and has shown unique therapeutic advantages. TCMs that promote blood circulation and remove blood stasis, such as Salvia miltiorrhiza, Carthami flos, Panax notoginseng, and Chuanxiong rhizoma, account for a large proportion of CHIs of cardio-cerebrovascular disease. CHI is used to treat cardio-cerebrovascular diseases and has potential pharmacological activities such as anti-platelet aggregation, anti-inflammatory, anti-fibrosis, and anti-apoptosis. However, CHIs have changed the traditional method of administering TCMs, and the drugs directly enter the bloodstream, which may produce new pharmacological effects or adverse reactions. This article summarizes the clinical application, pharmacological effects, and mechanism of action of different varieties of CHIs commonly used in the treatment of cardio-cerebrovascular diseases, analyzes the causes of adverse reactions, and proposes suggestions for rational drug use and pharmaceutical care methods to provide a reference for the rational application of CHIs for cardio-cerebrovascular diseases.

Relationship between the inserting sites of Fu's subcutaneous needling and traditional acupoints: revelation to acupuncture and moxibustion / 中国针灸

Focusing on the phenomenon of "de-acupoints" of the needle insertion sites in Fu's subcutaneous needling (FSN), the authors allocated the evolution and characteristics of the needle insertion sites of FSN. From six aspects, named morphology and structure, location, nomenclature, numbers and meridian tropism, indications and acupuncture manipulations, the comparison was made between the insertion sites of FSN and traditional acupoints. It is believed: ①The needle insertion sites of FSN has the basic attributes of acupoint, which not only refers to the operation site, but also indicates the reaction of disease; moreover, it is the treatment site with significant therapeutic effect. ②The optimized sites of insertion in FSN should be named differently and their locations and numbers should be specified relatively. ③The insertion sites of FSN should be further intersected and integrated with traditional acupoints, and a part of traditional acupoints should become the insertion sites of FSN. ④Accepting and integrating the insertion sites of FSN, and expanding the scope of traditional acupoints may be the new project in the research of traditional acupoints.

Material basis and mechanism of Huangqin Tea in prevention of colorectal cancer based on network pharmacology and molecular docking / 中国中药杂志

Colorectal cancer is a malignancy with high mortality. Huangqin Tea(HQT) can exert potential preventive and therapeutic effects on colorectal cancer. Flavonoids are the main compounds in HQT, but the pharmacodynamic material basis and mechanism are unclear. Network pharmacology and molecular docking were used to predict and analyze the targets and signaling pathways of HQT in the prevention and treatment of colorectal cancer. The active components of flavonoids in HQT were searched and screened out by literature review and FAFDrugs4. The related targets of active components were predicted by SwissTargetPrediction, STITCH, and TCMSP. Colorectal cancer-related genes were collected from OMIM, TTD, and GeneCards. The common targets were obtained as the potential targets of HQT in the prevention and treatment of colorectal cancer. Metascape was used for GO function enrichment and KEGG pathway enrichment analyses. Cytoscape was used to construct the protein-protein interaction(PPI) network and "component-target-disease-pathway" network to obtained and analyze core targets and key components. AutoDock Vina was used for molecular docking verification of key components and core targets. The results showed that apigenin, luteolin, wogonin, and baicalein were presumedly the key active components in the prevention and treatment of colorectal cancer, and core targets included TP53, AKT1, VEGFA, PIK3 CA, and SRC. The key KEGG signaling pathways mainly involved PI3 K-AKT, AGE-RAGE, p53, NF-κB, Wnt, Hippo, and calcium signaling pathways. Further molecular docking results showed that four key components showed strong hydrogen bonding ability with the five core targets. This study preliminarily reveals the pharmacodynamic material basis and potential mechanism of HQT in the prevention and treatment of colorectal cancer and provides a theoretical and scientific basis for the application of HQT.

Astragali Radix-Angelicae Sinensis Radix （AA） is a basic pair of drugs mainly targeting the syndrome characteristics of Qi and blood diseases. LI Dong-yuan's Danggui Buxuetang （DBT） is composed of AA， which is mainly used to tonify Qi and generate blood， with main indications of Qi deficiency and blood deficiency， blood heat and so on. It is favored by doctors because of its refined prescription and remarkable curative effect. However， there are many compatibility ratios of AA in different prescriptions in ancient books， and their efficacy and indications are also slightly different. This research showed that DBT also had the effect of invigorating Qi and activating blood， and the previous study of the group showed that 3∶1 compatibility ratio of the two herbs in the total amount of 36 g had more obvious effect of invigorating Qi and activating blood. By consulting the relevant literature， it was found that the drug pair had a certain effect of invigorating Qi and activating blood in various compatibility ratios such as 1∶1， 3∶1， 1∶5， 3∶2， 2∶1， 5∶1. The corresponding pharmacological effect mainly included regulating the energy metabolism of substances， regulating immune function， reducing blood viscosity， anti-oxidation stress， anti-inflammation， lowering blood lipids， lowering blood sugar， protecting heart function， protecting blood vessel wall， intervening angiogenesis， fighting against organ tissue fibrosis and so on. Regardless of the AA single-medicine's activating blood effect and the theory that "Qi circulation leads to blood circulation" or the drug pair's manifestation in modern pharmacological effects， all of these have confirmed that AA's effect of invigorating Qi and activating blood does exist， and the difference of action performance caused by different ratios of AA is closely related to dosage and proportion， which needs further study. Based on the study focusing on the effect of tonifying Qi and generating blood， it is easy to ignore the effect of invigorating Qi and activating blood， which limits the clinical application of the latter. Therefore， the tonifying Qi and activating blood circulation effect of the drug pair is reviewed in this paper， so as to provide a theoretical basis for its clinical rational drug use and related research.
