RESUMEN
OBJECTIVE: To reveal the anti-inflammatory mechanism of Guanxin V, which is prescribed for ventricular remodeling in clinical practice. METHODS: Guanxin V-, ventricular remodeling-, and inflammation-related targets were obtained through an integrated strategy of virtual screening and systematic pharmacology, and then the shared targets were visualised with a Venn diagram. Guanxin V network and the protein-protein interaction network were drawn, and enrichment analysis was conducted. Finally, the main results obtained from the integrated strategy were validated by molecular docking and in vivo experiments. RESULTS: A total of 251, 11,425, and 15,246 Guanxin V-, ventricular remodeling-, and inflammation-related targets were acquired, respectively. Then, 211 shared targets were considered to contribute to the mechanism of ventricular remodeling treated by Guanxin V. Guanxin network and the protein-protein interaction network were drawn, and enrichment analysis showed some cardiovascular-related biological processes and signaling pathways. Molecular docking revealed that the Guanxin V-derived compounds could align with key targets. Final in vivo experiments proved that Guanxin V reverses ventricular remodeling by inhibiting inflammation. CONCLUSION: Guanxin V relieves ventricular remodeling by regulating inflammation, which provides new ideas for the anti-ventricular remodeling mechanism of Guanxin V.

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.

Exposure of infectious biofilms to dispersants induces high bacterial concentrations in blood that may cause sepsis. Preventing sepsis requires simultaneous biofilm dispersal and bacterial killing. Here, self-targeting DCPA(2-(4-((1,5-bis(octadecenoyl)1,5-dioxopentan-2-yl)carbamoyl)pyridin-1-ium-1-yl)acetate) liposomes with complexed water were self-assembled with ciprofloxacin loaded in-membrane and PEGylated as a lipid-membrane component, together with bromelain loaded in-core. Inside biofilms, DCPA-H2O and PEGylated ciprofloxacin became protonated, disturbing the balance in the lipid-membrane to cause liposome-burst and simultaneous release of bromelain and ciprofloxacin. Simultaneous release of bromelain and ciprofloxacin enhanced bacterial killing in Staphylococcus aureus biofilms as compared with free bromelain and/or ciprofloxacin. After tail-vein injection in mice, liposomes accumulated inside intra-abdominal staphylococcal biofilms. Subsequent liposome-burst and simultaneous release of bromelain and ciprofloxacin yielded degradation of the biofilm matrix by bromelain and higher bacterial killing without inducing septic symptoms as obtained by injection of free bromelain and ciprofloxacin. This shows the advantage of simultaneous release from liposomes of bromelain and ciprofloxacin inside a biofilm.

Since the 18th National Congress of the Communist Party of China(CPC), the CPC and the government have highligh-ted the development of traditional Chinese Medicine(TCM) and issued a series of policies, such as the Plan for Protection and Deve-lopment of Chinese Medicinal Materials(2015-2020) forwarded by the General Office of the State Council in 2015, the Plan for Healthy Development of Traditional Chinese Medicine(2015-2020) released by the General Office of the State Council in the same year, the Healthy China 2030 Plan published by the CPC Central Committee and the State Council in 2016, the Law of the People's Republic of China on Traditional Chinese Medicine which took effect on July 2017, On the Preservation and Innovative Development of Traditional Chinese Medicine promulgated by CPC Central Committee and the State Council in 2019, and Plan for the Development of Traditional Chinese Medicine during the 14th Five-Year Plan Period of China released by the General Office of the State Council in March 2022, to promote the development of the TCM industry, which have brought historical opportunities to the TCM industry. However, TCM industry faces various challenges in the development. In terms of drug development in TCM, the current studies mainly focused on the chemical research and technical requests, which neglected TCM characteristics and cased in conformity between new drug transformation of TCM and clinical practice. Therefore, a more considerable and profound authoritative guideline is needed, and innovative thought and research are necessary for academics and the industry. Through the investigation of the development TCM industry in recent years, this study summarized the policies on and trends of Chinese medicinal materials, new drug development in TCM, catalogue of national basic drugs, and national basic health insurance, and proposed suggestions for further development of TCM industry.

The clinical comprehensive evaluation of Chinese patent medicine is an important direction in the evaluation of traditional Chinese medicine(TCM), which positively promotes the development of TCM industry. The evaluation system of Chinese patent medicine is helpful to comprehensively evaluate the clinical value of different Chinese patent medicine in the same category, different dosage forms, and specifications, from different manufacturers on the basis of evidence and value. The establishment of a scientific and reasonable comprehensive evaluation index system for Chinese patent medicine is an important prerequisite to ensure clinical value. However, there has been neither a recognized systematic review on the clinical comprehensive evaluation of Chinese patent medicine nor a methodological system used for reference. The evidence and value: impact on decision-making(EVIDEM), developed by the international research team, is used to evaluate the comprehensive value of medical interventions. EVIDEM provides a methodological tool for scientific decision-making to evaluate evidence and value for health technologies on the basis of the multi-criteria decision analysis(MCDA) model and health technology assessment(HTA). Based on the ongoing EVIDEM research, the present study put forward that EVIDEM-based clinical comprehensive evaluation of Chinese patent medicine consisted of four aspects, seven modules, and ten steps, which is expected to references and practical experience for the follow-up comprehensive evaluation of Chinese patent medicine in the TCM field.

BACKGROUND: Oxidative stress, apoptosis, and fibrosis have important roles in acute myocardial infarction, which is the main cause of global morbidity and mortality. Guanxin V significantly ameliorates acute myocardial infarction, the underlying mechanism, however, is still unclear. PURPOSE: In this study, we detected the anti-oxidative, anti-apoptotic, and anti-fibrosis effects of Guanxin V on acute myocardial infarction. METHODS: We used left anterior descending coronary artery ligation to construct an acute myocardial infarction model. Cardiac function, heart weight, infarction size, and histopathology were measured. Cardiomyocytes were treated with hydrogen peroxide to build an in vitro model. Cell apoptosis, fibrosis, and reactive oxygen species-related markers were tested. We observed the mitochondrial ultrastructure through transmission electron microscopy. The levels of collagens and TGF-ß1 signalling were measured. The lentiviral vector containing the full-length TGF-ß1 sequence was administered to investigate the rescue role of Guanxin V. RESULTS: Guanxin V significantly decreased apoptosis and inhibited oxidative stress damage and fibrosis in acute myocardial infarction. Hydrogen peroxide could stimulate cardiomyocytes to produce reactive oxygen species and Guanxin V could significantly reverse hydrogen peroxide-induced cell damage, inhibit oxidative stress damage, apoptosis, and fibrosis, and enhance mitochondrial dynamic balance. Mechanistically, Guanxin V attenuated oxidative stress damage, apoptosis, and fibrosis induced by the TGF-ß1 signalling pathway activation. CONCLUSIONS: Guanxin V effectively relieved apoptosis, oxidative stress damage, and fibrosis through down-regulating the TGF-ß1 signalling pathway, which enhances the knowledge of the cellular and molecular mechanism of Guanxin V in treating acute myocardial infarction.

BACKGROUND: Our previous study demonstrated that Guanxin V (GXV), a traditional Chinese herbal medicine, has a significant therapeutic effect on ventricular remodeling. However, the mechanistic action of GXV in ventricular remodeling warrants clarification. PURPOSE: Here, we aimed to explore the anti-ventricular remodeling contribution of GXV and to provide an experimental basis for clinical generalization. METHODS: A ventricular remodeling model after acute myocardial infarction was constructed in Syrian hamsters. The echocardiography and biochemical indices of cardiac function and remodeling were evaluated in different groups. Moreover, we built a remodeling model in cardiomyocytes and further explored the mechanism. Transmission electron microscopy was used to observe the ultrastructure of cardiomyocytes. The vital markers involved in the signaling pathway were detected by RT-qPCR and immunoblotting. Transforming growth factor beta 1 (TGF-ß1) was overexpressed with lentivirus to verify the necessity of TGF-ß1 in GXV's anti-ventricular remodeling effect. Finally, co-immunoprecipitation was conducted to test the interaction of TGF-ß1 and Vimentin. RESULTS: In hamster cardiac remodeling induced by acute myocardial infarction, GXV alleviated apoptosis, cardiac hypertrophy, and cardiac remodeling, and even improved cardiac function. Mechanistically, GXV inhibited the remodeling process by directly targeting TGF-ß1. Overexpression of TGF-ß1 exacerbated the ventricular remodeling, whereas GXV reversed this dysregulation. GXV also decreased the up-regulated Vimentin level in pathological ventricular remodeling. Moreover, the interaction of Vimentin and TGF-ß1 was confirmed by co-immunoprecipitation, and GXV impeded this interaction. CONCLUSION: We showed that the interaction of Vimentin and TGF-ß1 may be a novel target for ventricular remodeling and that GXV might be a new agent to fight against ventricular remodeling by targeting TGF-ß1 and impeding its interaction with Vimentin.

Objectives: We intend to conduct a meta-analysis on the systematic evaluation of traditional Chinese medicine (TCM) in the treatment of ventricular remodeling following acute myocardial infarction (AMI). Our findings may provide certain references for the clinical treatment of ventricular remodeling. Methods: A systematic literature search was conducted in PubMed, Web of Science, Cochrane Library, Embase, CNKI, Wanfang Data, CQVIP, and CBM before 20 July 2020. Data were analyzed using a random/fixed-effect model. Primary outcomes included the effectiveness and TCM syndrome score (TCMSS). Secondary outcomes included 1) echocardiography data, including the left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic volume index (LVEDVi), left ventricular end-systolic volume index (LVESVi), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), left ventricular ejection fraction (LVEF), E/A, stroke volume (SV), and wall motion score (WMS); 2) serum indicators, including the B-type natriuretic peptide (BNP) or N-terminal pro-B-type natriuretic peptide (NT-proBNP), and C-reactive protein (CRP) or high sensitivity CRP (hs-CRP); (3) major adverse cardiovascular events (MACE) and other adverse events Results: Forty RCTs involving 3,659 subjects were recruited. Our findings proved that a combination of TCM or TCM preparations with conventional Western medicine for preventing and reversing ventricular remodeling at post-AMI could remarkably enhance the total effectiveness and reduced TCMSS. Moreover, myocardial functions (LVEF, E/A, and SV), ventricular remodeling (LVEDVi, LVESVi, LVEDV, LVESV, LVEDD, LVESD, LVPWT, and WMS), serum levels of BNP and CRP, and MACE were significantly improved by the combination of TCM or TCM preparations with conventional Western medicine. Nevertheless, IVST and the incidence of other adverse events were comparable between control and experimental groups Conclusion: The combination of TCM or TCM preparations and conventional Western medicine can alleviate the process of ventricular remodeling, enhance cardiac function, and reduce the incidence of MACE in AMI patients.
RESUMEN
Traditional Chinese medicine(TCM) is an important feature of cancer treatment in China. The methods to tap the advantages of TCM, reasonably evaluate and accurately apply Chinese patent medicines have become current research hotspots and difficulties. TCM takes syndrome differentiation and treatment as the core, with the characteristics of overall regulation and multi-targets efficacy. Therefore, the post-marketing survival benefit evaluation of Chinese patent medicines for cancer is different from that in modern medicine. The primary treatment goals in cancer patients include to improve the disease control rate and prolong their survival time. At present, Chinese patent medicines for cancer patients are lacking indepth studies on survival benefit at the post-marketing stage. In addition, the characteristics of individualized treatment with TCM have also increased the complexity of clinical research on TCM. Therefore, it is of certain practical significance and necessity to evaluate the survival benefit of Chinese patent medicines for cancer after marketing. Based on this, in this paper, we first summarized the technical methodological means of survival benefit evaluation at this stage, and then explored the post-marketing survival benefit evaluation of Chinese patent medicines for cancer from three aspects: the evaluation of cancer treatment effect based on survival time and quality of life, treatment-related toxicity and the auxiliary effect of TCM, and the improvement effect for tumor-related symptoms. Based on the practices of early clinical researches, and according to the insufficient efficacy evaluation of current clinical research on Chinese patent medicines, this paper proposed to improve the evaluation system for clinical researches on Chinese patent medicines, establish the evaluation method with TCM characteristics, clarify the dominant population, lay a theoretical foundation for the evaluation of post-marketing survival benefits of Chinese patent medicines for cancer in the future, and promote the modernization process of TCM.

BACKGROUND: Guanxin V (GXV), a traditional Chinese medicine (TCM), has been widely used to treat coronary artery disease (CAD) in clinical practice in China. However, research on the active components and underlying mechanisms of GXV in CAD is still scarce. METHODS: A virtual screening and network pharmacological approach was utilized for predicting the pharmacological mechanisms of GXV in CAD. The active compounds of GXV based on various TCM-related databases were selected and then the potential targets of these compounds were identified. Then, after the CAD targets were built through nine databases, a PPI network was constructed based on the matching GXV and CAD potential targets, and the hub targets were screened by MCODE. Moreover, Metascape was applied to GO and KEGG functional enrichment. Finally, HPLC fingerprints of GXV were established. RESULTS: A total of 119 active components and 121 potential targets shared between CAD and GXV were obtained. The results of functional enrichment indicated that several GO biological processes and KEGG pathways of GXV mostly participated in the therapeutic mechanisms. Furthermore, 7 hub MCODEs of GXV were collected as potential targets, implying the complex effects of GXV-mediated protection against CAD. Six specific chemicals were identified. CONCLUSION: GXV could be employed for CAD through molecular mechanisms, involving complex interactions between multiple compounds and targets, as predicted by virtual screening and network pharmacology. Our study provides a new TCM for the treatment of CAD and deepens the understanding of the molecular mechanisms of GXV against CAD.

To investigate the effect of Yiqi Wenyang (YQWY) decoction on reversing cardiac hypertrophy induced by the transverse aortic constriction (TAC). Wistar rats aged 7-8 weeks were subjected to TAC surgery and then randomly divided into 4 groups (n = 5/group): Sham group, TAC group, low-dose group and high dose group. After 16-week intragastric administration of YQWY decoction, the effect of YQWY decoction on alleviating cardiomyocyte hypertrophy was examined by transthoracic echocardiography (TTE), hematoxylin/eosin (HE), wheat germ agglutinin (WGA) staining, enzyme linked immunosorbent assay (ELISA), Western blot (WB), immunohistochemistry (IHC) and immunofluorescence (IF), respectively. The results showed significant differences in left ventricle volume-diastole/systole (LV Vol d/s), N-terminal pro-B-type brain natriuretic peptide (NT-proBNP) (P < 0.01), Ejection Fraction (EF), LV mass and fractional shortening (FS) (P < 0.05) between YQWY-treated group and TAC group. HE and WGA staining showed that treatment with YQWY decoction dramatically prevented TAC-induced cardiomycyte hypertrophy. Moreover, the results of WB, IHC and IF indicated that administration of YQWY could suppress the expressions of cardiac hypertrophic markers, which included the atrial natriuretic peptide (ANP), BNP and myosin heavy chain 7 (MYH7) (P < 0.05) and inhibit phosphorylation of GATA binding protein 4 (P-GATA4) (P < 0.05), phosphorylation of extracellular signal-regulated kinase (P-ERK) (P < 0.05), phosphorylation of P38 mitogen activated protein kinase (P-P38) (P < 0.05) and phosphorylation of c-Jun N-terminal kinase (P-JNK) (P < 0.05). Thus, we concluded that YQWY decoction suppressed cardiomyocyte hypertrophy and reversed the impaired heart function, and the curative effects of YQWY decoction were associated with the decreased phosphorylation of GATA4 and mitogen activated protein kinases (MAPKs), as well as the reduced expression of the downstream targets of GATA4, including ANP, BNP, and MYH7.

The expert consensus on clinical practice of Chinese patent medicines shall be regarded as the same with clinical practice guidelines,which shall be concise,readable and applicable. Therefore,a formal expert consensus is unable to contain the whole compilation process and the content of its important process documents. It is necessary to write instructions for continuation,expansion and publicity. In 2018 Standardization Department of China Association of Chinese Medicine invited methodologists with the background of evidence-based medicine drafted a series of standards for expert consensus on clinical practice of Chinese patent medicines,including the guidance for compilation the instructions. It will be useful for readers of expert consensus to understand the work behind the compilation,so as to make the compilation process more transparent and standardized. We proposed nine requirements for compilation the instructions,namely content and requirements,work overview,main technical content,compilation process,process and basis for handling major disagreements,expert consensus implementation requirements and measure suggestions,other issues need to be explained,appendix and format for instructions.

Companion cropping with wheat (Triticum aestivum L.) can enhance watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] wilt disease resistance against Fusarium oxysporum f. sp. niveum. However, the mechanism of resistance induction remains unknown. In this study, the effects of microbial community dynamics and the interactions between wheat and watermelon plants, particularly the effect of wheat root exudates on watermelon resistance against F. oxysporum f. sp. niveum, were examined using a plant-soil feedback trial and plant tissue culture approach. The plant-soil feedback trial showed that treating watermelon with soil from wheat/watermelon companion cropping decreased watermelon wilt disease incidence and severity, increased lignin biosynthesis- and defense-related gene expression, and increased ß-1,3-glucanase activity in watermelon roots. Furthermore, soil microbes can contribute to increasing disease resistance in watermelon plants. Tissue culture experiments showed that both exogenous addition of wheat root exudates and companion cropping with wheat increased host defense gene expression, lignin and total phenols, and increased ß-1,3-glucanase activity in watermelon roots. In conclusion, both root exudates from wheat and the related soil microorganisms in a wheat/watermelon companion cropping system played critical roles in enhancing resistance to watermelon wilt disease induced by F. oxysporum f. sp. niveum.

Qing Gan Zi Shen Tang (QGZST) is a famous traditional Chinese medicine formula in the Jiangsu Province Hospital of Traditional Chinese Medicine for its efficacy in treating hypertension, obesity, hyperlipidemia and insulin resistance. The current study further evaluated the effects and possible mechanisms of QGZST on epididymal white adipose tissue (eWAT) dysfunction in a high-fat-diet (HFD)-fed-spontaneously hypertensive rat (SHR) model. Results showed that QGZST significantly decreased the systolic blood pressure (SBP), mean arterial blood pressure (MAP), body weights and adipocyte size of HFD-fed SHRs. Moreover, QGZST remarkably reduced the serum levels of cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting glucose, fasting insulin and HOMA-IR index, increased serum high-density lipoprotein cholesterol levels and improved glucose intolerance in HFD-fed SHRs. Furthermore, QGZST dramatically attenuated HFD-fed-induced hypersecretion of proinflammatory cytokines and hypoproduction of adiponectin in SHRs. Mechanistically, QGZST stimulated the activity of Sirtuin 1 (SIRT1) and Forkhead box protein O1 (FOXO1) and suppress the expression of peroxisome proliferator-activated receptor-γ (PPAR-γ), CCAAT-enhancer-binding proteins-α(C/EBP-α), fatty acid binding protein 4 (FABP4), acetylated nuclear factor-kappa-B-p65 (acetyl-NF-кB-p65) and protein-tyrosine phosphatase 1B (PTP1B). More than that, QGZST also prevented acetyl-NF-кB-p65 nuclear accumulation. Collectively, our research demonstrated for the first time that QGZST is able to alleviate eWAT dysfunction with up-regulation of SIRT1 in HFD-fed SHRs, which might supply further insight into QGZST-mediated anti-hypertension and anti-obesity effects.

Chinese patent medicine is widely used in clinical practice, but improper use will not only weaken the efficacy of drugs, but even cause adverse consequences. Evidence-based medicine provides guidance for clinical practice based on the best available evidence, experience of experts and needs of patients. However, considering the situation of "insufficient evidence" or "very low quality" in Chinese medicine research, experts consensus is the main basis for clinical decision-making, but expert opinions on which the consensus depends are susceptible to various subjective biases. Therefore, a reliable and scientific consensus-making process is needed to maximally avoid bias on consensus. Unlike the clinical practice guidelines, there is no unified formulating process for consensus in the world today. This article learns from a set of formulating processes from some international consensus formulating institutions/associations, combined with the characteristics and current situation of traditional Chinese medicine, and draws up a set of standard process that is suitable for the clinical experts consensus on Chinese patent medicine, with the expect of providing evidence and reference for consensus makers, and then bringing evidence-based assistance for the clinical standardized application of Chinese patent medicines.

As an important resource of functional food, the seeds of tree peony are rich in phenolic compounds, which are associated with antioxidant activity. However, so far there has not been systematic study on phenolic compositions and antioxidant activity of the seeds from wild tree peony species. The aim of this study was to determine the phenolic content, antioxidant compounds and antioxidant activity of seeds from nine tree peony species native to China. Among the seed samples, Paeonia rockii had the highest total flavonoid content, strongest DPPH and ABTS radical scavenging activities, and strongest cupric reducing capacity; P. decomposita subsp. rotundiloba had the highest total phenolic and flavanol contents, as well as the strongest hydroxyl radical scavenging activity. Sixteen individual phenolic compounds were quantitatively measured, with (+)-catechin being the most abundant component. The content of the phenolic compounds luteolin, paeonol, and the total flavonoid content were significantly correlated with four antioxidant activities. Hierarchical cluster analysis showed that P. rockii and P. decomposita subsp. rotundiloba could be clustered in a group having a high phenolic content and strong antioxidant activity. These results suggest P. rockii and P. decomposita subsp. rotundiloba are the most promising candidates as useful sources of natural antioxidants.

Clinical practice guideline (CPG) should be concise and readability, which can be possible to implement CPG into practice smoothly. A formal published CPG can't load its developing process and details. An editorial explanation of CPG is much useful to show details and logic process of developing CPG. Although there are many different standards for developing CPG, being nothing to do with process management of CPG. By referring to editorial explanation on international standards, a request for CPG was investigated in this study. An editorial explanation for clinical practice guideline should be transparency, logic and traceable. A good editorial explanation could make users or readers to learn what goes on behind the scenes. A standardized editorial explanation could supervise the GCP developing and improve the quality of GCP.
