An optimal medicinal and edible Chinese herbal formula attenuates particulate matter-induced lung injury through its anti-oxidative, anti-inflammatory and anti-apoptosis activities / 中草药·英文版

OBJECTIVE@#Identifying novel strategies to prevent particulate matter (PM)-induced lung injury is crucial for the reduction of the morbidity of chronic respiratory diseases. The combined intervention represented by herbal formulae for simultaneously targeting multiple pathological processes can provide a more beneficial effect than the single intervention. The aim of this paper is therefore to design a safe and effective medicinal and edible Chinese herbs (MECHs) formula against PM-induced lung injury.@*METHODS@#PM-induced oxidative stress, inflammatory response and apoptosis A549 cell model were used to screen anti-oxidant, anti-inflammatory and anti-apoptotic MECHs, respectively. A network pharmacology method was utilized to rationally design a novel herbal formula. Ultra performance liquid chromatography-mass spectrometer was utilized to assess the quality control of MECHs formula. The excretion of magnetic iron oxide nanospheres of the MECHs formula was estimated in zebrafish. The MECH formula against PM-induced lung injury was investigated with mice experiments.@*RESULTS@#Five selected herbs were rationally designed to form a new MECH formula, including Citri Exocarpium Rubrum (Juhong), Lablab Semen Album (Baibiandou), Atractylodis Macrocephalae Rhizoma (Baizhu), Mori Folium (Sangye) and Polygonati Odorati Rhizoma (Yuzhu). The formula effectively promoted the magnetic iron oxide nanospheres excretion in zebrafish. The mid/high dose formula significantly prevented PM-induced lung damage in mice by enhancing the activity of SOD and GSH-Px, reducing the MDA and ROS level and attenuating the upregulation of pro-inflammatory cytokine (IL-6, IL-8, IL-1β and TNF-α), down regulating the protein expression of NF-κB, STAT3 and Caspase-3.@*CONCLUSION@#Our findings suggest that the effective MECHs formula will become a novel strategy for preventing PM-induced lung injury and provide a paradigm for the development of functional foods using MECHs.

A Data Mining-Based Study on Medication Rules of Chinese Herbs to Treat Heart Failure with Preserved Ejection Fraction / 中国结合医学杂志

OBJECTIVE@#To summarize the medication rules of Chinese herbs to treat heart failure with preserved ejection fraction (HFPEF) based on data mining and to provide references for clinical utilization.@*METHODS@#The China National Knowledge Infrastructure (CNKI), Wanfang database (Wanfang), VIP database (VIP), Chinese Biomedical Literature (CBM), PubMed, Embase, and Cochrane Library databases were searched from inception to October 2021 to identify relevant literature on treating HFPEF with Chinese herbs. Microsoft Excel 2019 was used to set up a database, and then, association rule analysis and hierarchical cluster analysis were performed by using apriori algorithm and hclust function respectively in R-Studio (Version 4.0.3).@*RESULTS@#A total of 182 qualified papers were included, involving a total of 92 prescriptions, 130 Chinese herbs, and 872 individual herbs prescribed, with an average of 9.5 herbs per prescription. The six most frequently prescribed herbs were Astragali Radix (Huangqi), Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Glycyrrhizae Radix Et Rhizoma (Gancao), Cinnamomi Ramulus (Guizhi), and Ginseng Radix Et Rhizoma (Renshen). There were 35 herbs used more than 5 times, involving 11 efficacy categories. The top three categories were deficiency-tonifying herbs, blood-activating and stasis-removing herbs, and dampness-draining diuretic herbs. The most commonly used herbs were mainly warm and sweet. The primary meridian tropisms were Lung Meridian, Heart Meridian and Spleen Meridian. Association rule analysis yielded 26 association rules, such as Astragali Radix (Huangqi) & Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Cinnamomi Ramulus (Guizhi) & Atractylodis Macrocephalae Rhizoma (Baizhu). Hierarchical cluster analysis yielded four herb classes, and their functions were mainly qi-replenishing and yang-warming, blood-activating and diuresis-inducing.@*CONCLUSIONS@#HFPEF is the syndrome of root vacuity and tip repletion, and its core pathogenesis is "deficiency", "stasis", and "water", with "deficiency" being the most principal, which is closely related to Xin (heart), Fei (Lung), and Pi (Spleen). The treatment of this disease occurs by improving qi, warming yang, activating blood and inducing diuresis. Astragali Radix (Huangqi) with Salviae Miltiorrhizae Radix Et Rhizoma (Danshen) is the basic combination of herbs applied.

Anti-tumor Effect of Chinese Herbal Polysaccharides： A Review / 中国实验方剂学杂志

Tumor has become one of the major diseases threatening human health at present. Conventional therapies for tumor have serious side effects and are prone to drug resistance， while new therapies are expensive and impose a heavy burden on patients. Chinese herbs effective in the treatment of tumor contain a variety of natural active ingredients， and many anti-tumor drugs used in clinical practice are derived from Chinese herbs. Polysaccharides， ubiquitous in Chinese herbs， are easy to extract and have antitumor， antiviral， and antioxidant activities. Studies have demonstrated that the polysaccharides from Chinese herbs have significant anti-tumor effect and are characterized by multi-target and multi-mechanism functioning， which can avoid the development of drug resistance， exhibiting a great research value and the potential to be developed into novel anti-tumor drugs. Their anti-tumor mechanisms mainly include the inhibition of tumor proliferation， promotion of apoptosis， induction of autophagy， influence on cell cycle， inhibition of tumor angiogenesis， modulation of epithelial-mesenchymal transition （EMT） and immunity， promotion of tumor oxidative stress， and regulation of phosphatidylinositol 3-kinase/ protein kinase B （PI3K/Akt）， Toll-like receptor 4 （TLR4）， mitogen-activated protein kinase/nuclear factor-kappa B （MAPK/NF-κB）， adenosine 5'-monophosphate （AMP）-activated protein kinase/mechanistic target of rapamycin （AMPK/mTOR）， epidermal growth factor receptor/extracellular signal-regulated kinase （EGFR/ERK）， p53， and Wnt/β-catenin signaling pathways.

Comparative study on short and long-term intervention impacts of six Chinese herbs with cold or heat property on lipid and energy metabolism in mice / 中国中药杂志

This study selected three typical Chinese herbs with cold property(Rhei Radix et Rhizoma, Scutellariae Radix, and Coptidis Rhizoma) and another three with heat property(Cinnamomi Cortex, Zingiberris Rhizoma, and Aconiti Lateralis Radix Praeparata) to observe their regulatory effects on metabolism in animal organism, especially on lipid and energy metabolism in mice after a short-(7 d) and long-term(35 d) intervention. The mRNA expression levels of lipid metabolism genes in epididymal adipose tissue and liver were determined by real-time PCR. The oxygen consumption, carbon dioxide production, and energy consumption were detected by metabolic system. After the short-term intervention, the Chinese herbs with heat property significantly reduced epididymal adipose tissue index and elevated the expression levels of acetyl-CoA carboxylase(ACC), lipoprotein lipase(LPL), and carnitine-palmityl transferase 1(CPT-1) in liver and epididymal adipose tissues. However, those with cold property promoted the expression of above-mentioned genes in epididymal adipose tissue. After the long-term intervention, cold and heat Chinese herbs had no significant effect on epididymal adipose tissue index of animals, while cold Chinese herbs could increase carbon dioxide production and energy consumption and reduce activity. These findings demonstrated that the short-term intervention effects of cold and heat Chinese herbs on animal metabolism were significantly stronger than the long-term intervention effects. Specifically, the short-term intervention with cold Chinese herbs enhanced the lipid metabolism in epididymal adipose tissue, while the heat Chinese herbs promoted lipid metabolism in epididymal adipose tissue and liver. The long-term intervention with cold and heat Chinese herbs resulted in no obvious change in lipid level, but long-term intervention with cold Chinese herbs accelerated energy consumption of the body. This study preliminarily observed the effects of cold and heat Chinese herbs on normal animal physiology from lipid and energy metabolism, which would provide reference for explaining the biological basis of Chinese herbs with cold or heat property based on biological response.

Mathematical Model for Analyzing Five Flavor Compatibility-transformation Theory in Tangye Jingfatu / 中国实验方剂学杂志

Objective:<italic>Auxiliary Verse on Drugs and</italic> <italic>methods</italic> <italic>for Zang-Fu Organs （Fuxingjue Wuzangyongyao Fayao）</italic> written by TAO Hong-jing from the Liang dynasty covered many contents from<italic> </italic>a missing prescription book<italic> Classic of Decoction （Tangye Jingfa）</italic>， including a map revealing the compatibility principle of Chinese herbs， namely the Tangye Jingfatu. Represented by a centrosymmetric pentagon， the map describes a unique theoretical system for deficiency-excess syndrome differentiation of five Zang organs （liver， heart， spleen， lung and kidney） and the tonification-purgation and compatibility theory of five flavors （pungent， salt， sweet， sour and bitter）. Each Zang organ fixedly corresponds to one "property" flavor （purgation）， one "function" flavor （tonification） and one "transformation" flavor （harmonization） resulting from the combination of the former two. For example， the liver can be purged by sour， tonified by pungent， and moderated by sweet transformed by the combination of sour with pungent. The heart can be purged by bitter， tonified by salt， and astringed by sour transformed by the combination of bitter with salt. The spleen can be purged by pungent， tonified by sweet， and dried by bitter transformed by the interaction between pungent and sweet. The lung can be purged by salt， tonified by sour， and dispersed by pungent transformed by the combination of salt with sour. The kidney can be purged by sweet， tonified by bitter， and moistened by salt transformed by the combination of sweet with bitter. This study selected appropriate mathematical tools to analyze the fixed relationship between "property" flavor， "function" flavor and "transformation" flavor among the five Zang organs in “Tangye Jingfatu” and establish a mathematical model revealing the compatibility-transformation relationship among five flavors. Method:Based on the group representation of five elements （wood， fire， earth， metal， and water）， the correlations of "property" flavor， "function" flavor， and "transformation" flavor with five elements’ generation-restriction were deduced based on matrix calculation and group theory. The three-dimensional calculation method for vector product was expanded for establishing the mathematical operator of five flavors' compatibility-transformation. Result:<bold>and</bold> Conclusion:There is a mapping relationship of the purging， tonifying， and harmonizing functions represented by the "property" flavor， "function" flavor， and "transformation" flavor of the five zang organs in the "Tangye Jingfatu" with the five elements' generation-restriction. The established mathematical operator contributes to explaining the fixed collocations of five flavor transformation. Based on such algorithm， the tonifying and purging characteristics of five flavors in 10 representative classic prescriptions have been clearly expounded.

Anti-inflammatory mechanism of heat-clearing and detoxifying Chinese herbs / 中国中药杂志

Heat-clearing and detoxifying Chinese herbs (HDCHs) are mainly used to treat carbuncle, sore throat, erysipelas, gills, dysentery and other diseases induced by heat-toxicity. Inflammation is a defensive response to damaging factors in living organism with vascular system. In recent years, a large amount of experimental and clinical studies showed that HDCHs had good therapeutic effect on inflammation. This review analyzed the anti-inflammatory mechanism of 11 HDCHs by retrieving literature in past 5 years, including Lonicerae Japonicae Flos (Jinyinhua), Lonicerae Flos (Jinyinhua), Lonicerae Japonicae Caulis (Rendongteng), Forsythiae Fructus (Lianqiao), Rhizoma Coptidis（Huanglian）, Gardeniae Fructus (Zhizi), Andrographis Herba (Chuanxinlian), Taraxaci Herba (Pugongying), Scrophulariae Radix (Xuanshen), Pulsatillae Radix (Baitouweng), and Agrimoniae Herba (Xianhecao). The data showed that the regulatory effect of HDCHs on inflammation may be involved mainly in the nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK) or janus kinase-signal transducers and activators of transcription (JAK-STAT) pathway, with similarity of action links among these three. Based upon the analysis of literature, we proposed some promising directions in this research field, providing a reliable theoretical basis for both experimental researches and clinical practices of HDCHs.
