ABSTRACT
COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread across the globe, posing an enormous threat to public health and safety. Traditional Chinese medicine (TCM), in combination with Western medicine (WM), has made important and lasting contributions in the battle against COVID-19. In this review, updated clinical effects and potential mechanisms of TCM, presented in newly recognized three distinct phases of the disease, are summarized and discussed. By integrating the available clinical and preclinical evidence, the efficacies and underlying mechanisms of TCM on COVID-19, including the highly recommended three Chinese patent medicines and three Chinese medicine formulas, are described in a panorama. We hope that this comprehensive review not only provides a reference for health care professionals and the public to recognize the significant contributions of TCM for COVID-19, but also serves as an evidence-based in-depth summary and analysis to facilitate understanding the true scientific value of TCM.
ABSTRACT
Traditional Chinese medicine (TCM) has a long history in treating infectious diseases, and the form of intervention varies with different medical conditions and disease types. "The battle field of Chinese doctor for anti-epidemic" was formed in fighting against severe acute respiratory syndrome (SARS) epidemics in China, and from the battle, valuable experiences of using TCM for prevention and treatment had been obtained. During responding to coronavirus disease 2019 (COVID-19) epidemics, we followed the principle of keeping summary and perfection while treament. And a whole process of TCM pattern or a model was organized, including early prevention in communities, cluster intervention in isolated places, comprehensive intervention in mobile cabin hospitals, centralized treatment in designated hospitals and rehabilitation support in rehabilitation posts. Thus, the innovation of whole process of TCM intervention was involved in the "trench warfare" strategy and platform system for prevention and treatment of new infectious COVID-19 epidemics. At different stages or conditions, different TCMs were used to play advantageous roles to solve various problems and elevate the effects of prevention and treatment of the disease. The construction of TCM mobile cabin hospitals was an innovation of organization form that might offset the constraints in technology and scale of simple community isolation or simple hospital treatment, exploring a new way for TCM to cope with public health emergencies.
ABSTRACT
Chinese medicinal materials occupy an important position in China's health industry. However, its overall quality needs to be improved and it is in urgent need of regulation. Exploring the formation of effective organizational mechanisms and industry models has become an urgent need of the industry. In this context, the alliance of coconstruction and sharing Chinese herbal medicine base came into being. The alliance is based on the pursuit of the quality of Chinese herbal medicines and continues to promote the construction of Chinese herbal medicines. The Alliance provides a platform for economic and scientific cooperation in the industry. Its purpose is to guide the promotion of the standardization of local varieties and the construction of modern Chinese medicine agricultural enterprises based on the development needs of Chinese herbal medicine resources and the common interests of all members. As an important content, we will strive to expand the new pattern of coordinated development of traditional Chinese medicine agriculture and industry, explore the establishment of a new organizational system for modern Chinese medicine agricultural production with controllable quality, output and price under the link of production and demand. For the sustainable, stable and healthy development of the Chinese medicine industry, it will serve 1.3 billion people and serve humanity, provide high-quality sustainable Chinese herbal medicine resources. Since its establishment six years ago, the alliance has carried out work on key aspects such as standardized production of Chinese herbal medicines, plant protection, decoction processing, supply and demand docking, medicinal materials standards, poverty alleviation, breeding, and provided technical support to enterprises. During this period, the alliance also proposed the concept of"three-no and one- all"requires the members to take the lead in achieving the standards of"sulfur- free processing, no aflatoxin pollution, pollution-free, traceable throughout the whole", setting a benchmark for the industry.
ABSTRACT
Background. Immunosuppression is a well-recognised complication of chemotherapy in cancer patients. We assemble the clinical evidence that SQI, an adjuvant drug for lung cancer and gastric cancer which was widely prescribed in China, interventions could increase objective tumour response and regulate immunity in cancer patients undergoing chemotherapy. Methods. We undertook a systemic review of the clinical data from randomised controlled trials up to September 2015 in which a SQI intervention was compared with a control arm in patients undergoing conventional chemotherapy. Revman 5.0 Software was used for the data analysis. Results. 49 randomised controlled trials were included in the systematic review. The meta-analysis results demonstrated that the SQI intervention with conventional chemotherapy exhibited better therapeutic efficacy than the conventional chemotherapy group with a statistically significant higher objective tumour response. Cotreatment with SQI could enhance NK, CD3+, CD4+ level, and CD4+/CD8+ ratio comparing with the conventional chemotherapy group. Conclusions. The conclusions of this review might suggest a high risk of bias due to the low quality and the limitation of cancer types in the included trials. A more reliable conclusion regarding the immunoregulation of SQI could be reached based on more trials of higher quality.
ABSTRACT
Tanshinone IIA (Tan IIA) is a pharmacologically active substance extracted from the rhizome of Salvia miltiorrhiza Bunge (also known as the Chinese herb Danshen), and is widely used to treat atherosclerosis. The pregnane X receptor (PXR) is a nuclear receptor that is a key regulator of xenobiotic and endobiotic detoxification. Tan IIA is an efficacious PXR agonist that has a potential protective effect on endothelial injuries induced by xenobiotics and endobiotics via PXR activation. Previously numerous studies have demonstrated the possible effects of Tan IIA on human umbilical vein endothelial cells, but the further mechanism for its exerts the protective effect is not well established. To study the protective effects of Tan IIA against hydrogen peroxide (H₂O₂) in human umbilical vein endothelial cells (HUVECs), we pretreated cells with or without different concentrations of Tan IIA for 24 h, then exposed the cells to 400 μM H₂O₂ for another 3 h. Therefore, our data strongly suggests that Tan IIA may lead to increased regeneration of glutathione (GSH) from the glutathione disulfide (GSSG) produced during the GSH peroxidase-catalyzed decomposition of H₂O₂ in HUVECs, and the PXR plays a significant role in this process. Tan IIA may also exert protective effects against H₂O₂-induced apoptosis through the mitochondrial apoptosis pathway associated with the participation of PXR. Tan IIA protected HUVECs from inflammatory mediators triggered by H₂O₂ via PXR activation. In conclusion, Tan IIA protected HUVECs against H₂O₂-induced cell injury through PXR-dependent mechanisms.

ABSTRACT
Aim To investigate the induction effect of ginsenoside Rc, Re, Rf and Rg1 on CYP1A1, and further validate the role of aryl hydrocarbon receptor in CYP1A1 expression. Methods Dual luciferase re-porter gene system was performed. Four kinds of gin-senoside were screened for aryl hydrocarbon receptor activation by reporter assays, and TCDD as the positive control. Further with different concentrations of ginsen-oside Rc, Re, Rf and Rg1 treated on LS174T cells, RNA and total protein were extracted to detect the reg-ulating effect of ginsenosides on CYP1 A1 mRNA and protein expression with Real-time PCR and Western blot technology respectively. Results Reporter gene screening showed that the ginsenoside Rc, Re, Rf and Rg1 could activate AhR and had potential effects on the induction of CYP1A1 enzyme. Meanwhile, dose-de-pendent induction of the gene expression were observed in response to ginsenoside Rc, Re, Rf and Rg1 and the levels of CYP1 A1 protein expression were increased by ginsenoside Rc, Re, Rf and Rg1 in varying de-grees. Conclusion Ginsenoside Rc, Re, Rf and Rg1 can up-regulate the gene and protein expression of CYP1 A1 possibly via the AhR-mediated CYP1 A1 path-way.
ABSTRACT
The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.
ABSTRACT
The paper is to report the study of the effect of Shenfu injection on the enzyme activity of liver CYP450 and its mRNA level of rat liver. Microsome of rat liver was prepared after intravenous administration of Shenfu injection for 7 days. The enzyme activity was quantified by Cocktail method. Meanwhile, the mRNA expression of CYP1A2, CYP2B1/2, CYP2C11 and CYP3A1 in the liver was detected by RT-PCR. Shenfu injection obviously induced the enzyme activities of CYP2B and CYP2C. Meantime Shenfu injection decreased the enzyme activities of CYP1A2 and CYP3A. The mRNA levels of CYP2B and CYP2C were also induced in rats treated with Shenfu injection. But it obviously inhibited the mRNA level of CYP1A2 and CYP3A. Since the enzyme activity and mRNA level were obviously changed after administration, the potential effect of drug-drug interaction should be concerned.
ABSTRACT
In order to study effects of ginseng on the metabolism of drug belong to CYP3A4 substrate, screening of pregnane X receptor activation from ginsenosides was performed by reporter assay. Based on PXR-CYP3A stable translation cell lines, 13 ginsenosides were screened for pregnane X receptor activation by reporter assays, and RIF as the positive control. The effect of ginsenosides Rg1 onCYP3A4 mRNA expression was also investigated by RT-PCR. The PXR-CYP3A stable translation cell lines had good response to RIF, and the EC50 is 2.51 micro mol x L(-1). When the condition of final concentration was 10 micromol x L(-1), ginsenoside F2 and protopanaxatriol had moderate inductive effects on PXR. Panaxotriol, Rg2, pseudoginsenoside F11, Rg1, ginsenoside and Rb3 had inhibitory effects on PXR. Ginsenoside Rf1, Rg3, Rh2 and protopanaxdiol had no obvious effects on PXR. Rg1 down-regulated CYP3A4 mRNA expression in a concentration-dependent manner. Activation of pregnane X receptor by ginsenosides may influence the metabolism of drug belong to CYP3A4 substrate, and cause ginseng-drug interactions.
ABSTRACT
ObjectiveTo evaluate the gastroprotective activity of ascaridole.MethodsThe gastroprotective effect of ascaridole was evaluated on ulcer healing in rats with acetic acid-induced chronic gastric ulcer,pylorus ligation- and Aspirininduced gastric ulcer.Ascaridole was ig administered with the dosages of 10 and 20 mg/kg once daily for 7 d.Results Ascaridole showed the significant anti-ulcer effects.In acetic acid-induced gastric ulcer rats,the ulcer areas after 10 and 20 mg/kg of ascaridole treatment were (65.1 ± 20.0) and (50.6 ± 11.0) mm2,respectively,which were significant lower (P ＜ 0.01) than that of the control group [(116.7 ± 35.8) mm2].For pylorus ligation model,ascaridole showed a gastric ulcer healing effect in a dose-dependent manner.Ascaridole at the dose of 20 mg/kg showed 50％ ulcer protection and had a significant (P ＜ 0.05) gastroprotective activity since it decreased the total acidity and pepsin activity.Compared to the control group,the two dosages of ascaridole showed the significant reduction (P ＜ 0.05) in the ulcer index on Aspirin-induced ulcer.ConclusionThis study provides evidence that ascaridole shows potential efficacy on the healing of gastric ulcers induced by acetic acid,Aspirin,and pylorus ligation.
