OBJECTIVE: Hypertension is a low-grade inflammation state of the disease and was easily complicated by kidneys' inflammatory response. Mangiferin (MGF), a pharmacologically active compound in various plants including Mangifera indica, has a strong anti-inflammatory activity. However, the effects of MGF on renal inflammatory injury in spontaneously hypertensive rats (SHRs) remain unclear. The purpose of this study was to investigate the protective effects and mechanisms of MGF on renal inflammatory injury in SHRs. METHODS: MGF was used in SHRs at the doses of 10, 20, 40 mg/kg/d for 8 weeks consecutively. The blood and urine were collected for assessment of renal function. Renal tissues were collected for histological, immunohistochemistry, ELISA, Western blot and real time reverse transcription PCR (RT-PCR) analysis. RESULTS: The results showed that the levels of interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1 (MCP-1) and recombinant chemokine C-C-Motif receptor 2 (CCR2) were increased in SHRs, meanwhile, the level of IL-10 was decreased in SHR. Treatment of MGF inhibited the expression of IL-6, TNF-α, MCP-1 and CCR2, and promoted the expression of IL-10. Furthermore, the content of blood urea nitrogen (BUN) and serum uric acid (SUA) was significantly increased in the model group, and treatment of MGF had no obvious effects on these parameters at all dose levels. CONCLUSION Our study proved that the kidneys of SHRs had significant inflammatory injury, and MGF had the protective effects on renal inflammatory injury in SHRs; The protective mechanism may be mediated partly by the MCP-1/CCR2 signaling pathway. Thus, it is a potential new drug for the treatment of hypertension.

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The antiliver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its “pharmacodynamic group”. By searching the research on the antihepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an antihepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an antihepatoma role. Network pharmacological analysis showed that the core targets of the “pharmacodynamic group” for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and “pharmacodynamic group”, it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and “pharmacodynamic group” in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and “pharmacodynamic group”.

Alzheimer's disease （AD） is one of the most common diseases in the elderly population. Its etiology involves multiple pathogenic factors and pathological links such as abnormal deposition of β amyloid protein （Aβ）， hyperphosphorylation of Tau protein， abnormalities of the cholinergic system， oxidative stress， and inflammatory response. However， its specific pathogenesis has not been clarified， and no specific therapeutic drugs have been found. In recent years， more and more studies have paid attention to the potential of chemical components of traditional Chinese medicine （TCM） in the treatment of AD. However， the diversity and complexity of the chemical components of TCM may have a positive impact on multiple pathological links of AD. Researchers have isolated many active components from TCMs， and the effects of treating AD have been confirmed by modern pharmacological studies. Through literature analysis， this article found that the main chemical components of TCM with anti-AD effects were saponins （31%）， flavonoids （24%）， polysaccharides （20%）， lactones （8%）， alkaloids （7%）， phenols （3%）， and other compounds （7%）. Among them， ginsenoside， notoginsenoside， epimedium flavones， puerarin， baicalein， schisandra polysaccharide， angelica polysaccharide， ganoderma lucidum polysaccharide， pachyman， huperzine A， berberine， andrographolide， curcumin， emodin， and gastrodin have been extensively studied in terms of their anti-AD effects， and their mechanisms of pharmacological action have been involved in many aspects of AD pathogenesis. This article reviews the anti-AD activities and possible mechanisms of chemical components of TCM， so as to provide a reference for the development of new drugs for the prevention and treatment of AD.

Glycyrrizae Radix et Rhizoma has high medicinal value and is widely used in compatibility. It is used most frequently in the compatibility of Chinese medicine prescriptions，and is known as ''Guolao''（national medicine） and "master of all medicines". The characteristic active ingredients are mainly liquitin，glycyrrizic acid，glycyrrizin，and licochalcone. In different compatibilities，based on traditional and modern pharmacological theories，the corresponding effect of Glycyrrizae Radix et Rhizoma are brought into play through different mechanisms. Based on the traditional pharmacology of Glycyrrizae Radix et Rhizoma for tonifying spleen，replenishing Qi，clearing heat，removing toxin，dispelling phlegm，relieving cough and pain，and harmonizing various medicines，this paper used herbal authentication to analyze its compatibility application and mechanism. It was found that Glycyrrizae Radix et Rhizoma played corresponding effect in compatibilities through "tonification"，"harmonization"，and "regulation". For example，Glycyrrizae Radix et Rhizoma was combined with tonics including Ginseng Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma to tonify the five Zang-organs through its strong tonifying effect，combined with Paeoniae Radix Alba and Aconiti Lateralis Radix Praeparata to relieve emergencies and pains through harmonizing medicine power and properties，and combined with Rhei Radix et Rhizoma and Natrii Sulfas to reduce medicine intensity through regulating medicine properties and body characteristics. The application law and mechanism of the modern pharmacological compatibility of Glycyrrizae Radix et Rhizoma were analyzed by data mining and network pharmacology. It was found that the modern clinical formula was often compatible with Glycyrrizae Radix et Rhizoma for anti-inflammation，cardiovascular and cerebrovascular protection，anti-virus，and anti-tumor，Ephedrae Herba and Scutellariae Radix for anti-inflammation，Bambusae Caulis in Taenias，Salviae Miltiorrhizae Radix et Rhizoma，and Aurantii Fructus Immaturus for cardiovascular and cerebrovascular protection，and Ophiopogonis Radix and Chuanxiong Rhizoma for nerves protection. Meanwhile，the important targets of the characteristic ingredients were protein kinase B1 （Akt1），interleukin-6 （IL-6），tumor necrosis factor （TNF），and epidermal growth factor receptor （EGFR）. The important characteristic pathways such as tyrosine kinase inhibitor resistance pathway and cyclic guanosine monophosphate （cGMP）/protein kinase G （PKG） signal pathway played the role of cardiovascular and cerebrovascular protection，and proteoglycan pathway in cancer played a neuroprotective role. This study is expected to provide references for the rational compatibility and application of Glycyrrizae Radix et Rhizoma，as well as the compatibility application of Chinese medicine prescriptions.
