Discussion on reprogramming of tumor energy metabolism and intervention of traditional Chinese medicine based on the theory of“collateral Q i stagnation”

The theory of stagnation of collateral Qi(Chinese medicine refers to the most fundamental and subtle substances thatconstitute the human body and maintain life activities,and also has the meaning of physiological functions)originates from the theory of collateral disease,which refers to the deficiency of Qi in the body’s collaterals,the loss of Qi and blood,and the failure of stagnation of collateral Qi,which leads to the loss of Qi,blood and body fluid,and the formation of pathological products such as deficiency,depression,phlegm,blood stasis in the local area,and ultimately damage the pathological process of collaterals.Based on the in-depth study of the pathogenesis of collateral Qi stagnation and the previous study of meridian channels,we believe that the key pathogenesis of the formation,evolution and spread of malignant tumors is“collateral Qi deficiency stagnation,collateral Qi stagnation and collateral Qi decay”.As an important energy resonance channel of the body,meridians play a key role in the process of material transformation and energy metabolism.It is believed that the small focus caused by the pathogenesis of stagnation is the cause of malignant transformation of tumor,the reprogramming of energy metabolism induced by the lesion of collateral Qi is the basis of the progress of tumor pathogenesis,and the formation of tumor microenvironment regulated by the tumor toxin vena is the root of alienation of tumor development.Guided by this theory,focusing on the correlation between collateral Qi and tumor energy metabolism,using Professor Hua Baojin's treatment method of“Regulating Qi and detoxifying”to prescribe drugs can adjust collateral Qi function,achieve the relative balance of internal environment,and then inhibit the progress of tumor.Based on the above understanding,this study tries to enlighten new diagnosis and treatment ideas under the guidance of“stagnation of collateral Qi”in traditional Chinese medicine,in order to provide some theoretical support for the intervention of traditional Chinese medicine in the process of tumor development.

Research progress of traditional Chinese medicine in regulating tumor microenvironment

The tumor microenvironment(TME)plays a crucial role in facilitating tumorigenesis and progression.Consequently,there is significant research interest within the oncology community in developing interventions that target the TME.Extensive research has been conducted on the mechanism of traditional Chinese medicine(TCM)in tumor therapy,revealing notable similarities between its theoretical framework and that of the TME.TCM has the ability to regulate various components of the microenvironment,including the modulation of proportions of T cell subsets,enhancement of the quantity and activity of NK cells,regulation of polarization of tumor-associated macrophages,suppression of expression of myeloid-derived suppressor cells,reduction of accumulation of tumor-associated endothelial cells,downregulation of the quantity and function of tumor-associated fibroblasts,and modulation of the architecture of the extracellular matrix.These multifaceted interventions ultimately lead to the attainment of anti-tumor objectives.This comprehensive review encompasses a thorough analysis of relevant literature from both domestic and international sources,with a specific emphasis on elucidating the mechanisms through which TCM compound formulas,single drugs,and monomeric components regulate the TME.

General Survey of Traditional Chinese Medicine and Western Medicine Researches on Tumor Metastasis

Metastasis and recurrence of tumors is the chief cause of death for such patients. Therefore, researches on the mechanism of its metastasis, prevention and treatment are the focal points in the field of traditional Chinese medicine （TCM） and Western medicine （WM） at present. WM practitioners＂ study on tumor metastasis involved its occurrence and development including every detail and process, and now it even has developed into the molecular biological field. py is used as the main means, but the efficacy is not n treatment surgical operation and radio- chemotheratoo optimistic. In recent years, TOM, as part of the comprehensive therapy, has been gradually gaining attention of oncologists. Aimed at solving the difficult problems in metastasis of tumor, many TOM practitioners on the basis of syndrome differentiation have raised theories about the cause of tumor metastasis. On the basis of these theories, some TOM recipes against tumor metastasis have been developed to serve as an effective supplement to surgical operation, radio- and chemotherapy. The present article summarizes research results in recent years about the cause of formation of tumor and its metastasis by TOM and WM, so as to offer some theoretical clues to the study of tumors metastasis.

From traditional Chinese medicine formulations to effective anticancer agents:Insights from Calculus bovis

This editorial examines the therapeutic potential of traditional Chinese medicine(TCM)for aggressive cancers,particularly liver cancer.It highlights the study by Huang et al,which shows how Calculus bovis,a component of the TCM Pien Tze Huang,suppresses liver cancer by inhibiting M2 macrophage polarization via the Wnt/β-catenin pathway.This research emphasizes the importance of transitioning from effective TCM formulations to isolating active components and understanding their mechanisms.While the study provides valuable insights,it primarily focuses on the Wnt/β-catenin pathway and does not delve deeply into the mechanisms of individual components.Future research should aim to comprehensively study these components,explore their interactions,and validate findings through clinical trials.This approach will integrate traditional wisdom with modern scientific validation,advancing the development of innovative cancer treatments based on TCM formulations.

Screening of traditional Chinese medicine monomers as ribonucleotide reductase M2 inhibitors for tumor treatment

BACKGROUND Ribonucleotide reductase(RR)is a key enzyme in tumor proliferation,especially its subunit-RRM2.Although there are multiple therapeutics for tumors,they all have certain limitations.Given their advantages,traditional Chinese medicine(TCM)monomers have become an important source of anti-tumor drugs.Therefore,screening and analysis of TCM monomers with RRM2 inhibition can provide a reference for further anti-tumor drug development.AIM To screen and analyze potential anti-tumor TCM monomers with a good binding capacity to RRM2.METHODS The Gene Expression Profiling Interactive Analysis database was used to analyze the level of RRM2 gene expression in normal and tumor tissues as well as RRM2's effect on the overall survival rate of tumor patients.TCM monomers that potentially act on RRM2 were screened via literature mining.Using AutoDock software,the screened monomers were docked with the RRM2 protein.RESULTS The expression of RRM2 mRNA in multiple tumor tissues was significantly higher than that in normal tissues,and it was negatively correlated with the overall survival rate of patients with the majority of tumor types.Through literature mining,we discovered that berberine,ursolic acid,gambogic acid,cinobufagin,quercetin,daphnetin,and osalmide have inhibitory effects on RRM2.The results of molecular docking identified that the above TCM monomers have a strong binding capacity with RRM2 protein,which mainly interacted through hydrogen bonds and hydrophobic force.The main binding sites were Arg330,Tyr323,Ser263,and Met350.CONCLUSION RRM2 is an important tumor therapeutic target.The TCM monomers screened have a good binding capacity with the RRM2 protein.

How do Chinese medicines that tonify the kidney inhibit dopaminergic neuron apoptosis?

Wistar rats were intragastrical y perfused with Chinese medicines used for tonifying the kidney. These included 0.180 g/mL of Herba Epimedi （Epimedium）, Semen Cuscutae （Dodder Seed）, or Herba Cistanches （Desertliving Cistanche）, 0.04 mg/mL monoamine oxidase-B inhibitor selegiline, or distil ed water for 14 consecutive days to prepare drug-containing serum or blank serum. MES23.5 cells in the logarithmic phase were cultured in media supplemented with 15%drug-containing serum for 24 hours, fol owed by incubation in culture solution containing 100μmol/L H2O2 for 3 hours. 3-（4,5-Dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide （MTT） and flow tometry results showed that al drug-containing serums improved the survival rate of H 2 O 2-injured MES23.5 cells, inhibited pro-apoptotic FasL and caspase-3 expression, promoted anti-apoptotic Bcl-2 expression. However, drug-containing serums had little influence on Fas expression in H 2 O 2-injured MES23.5 cells. Enzyme-linked immunosorbent assay results showed that serum containing Herba Cistanches or Herba Epimedi increased the expression of nerve growth factor, brain-derived neurotrophic factor, and glial cellline-derived neurotrophic factor in injured MES23.5 cells;serum containing Semen Cuscutae only increased brain-derived neurotrophic factor expres-sion; while expression of the above neurotrophic factors remained the same in cells treated with serum containing selegiline. These findings indicate that Chinese medicines used to tonify the kid-ney can protect nerve cells by regulating the expression of apoptosis-related factors and neuro-trophic factors in MES23.5 cells.

Annual advances in traditional medicine for tumor therapy in 2019

Today,the treatment of tumors remains a difficult problem.Traditional medicine has been used to treat cancer in different countries worldwide.However,while traditional medicine is popular globally,it is not yet accepted by Western medicine as some of the ingredients and the mechanism of action for the therapeutic effect have not been fully elucidated.Thus,scholars studying traditional medicine in the treatment of cancer have strived to solve this problem.In this review,we summarized the research progress of several traditional medicines used as tumor therapies in 2019 from the PubMed database.Studies of tumors treated with traditional Chinese medicine(TCM)are popular worldwide and obtain the most attention,which attracts more researchers to this field.The anti-tumor effects of Chinese herbal medicine-derived phytochemicals,such as polyphenols,polysaccharides,saponins,and alkaloids were the new research targets for 2019.The anti-tumor effects of TCM formula such as Sijunzi decoction,and Xiaopi formula have attracted the most attention in the past year.In addition to TCM,we also focused on the anti-tumor studies of other traditional medicines,including Thai traditional medicine,traditional medicine in Sri Lanka,traditional African medicine,traditional Korean medicine,and traditional Japanese medicine.

Annual advances of traditional medicine on tumor immunity regulation in 2020

Tumor burden remains a global health problem that threatens human life worldwide.Over the past few years,the evolution of immune checkpoint inhibitors has represented one of the most successful approaches in the field of tumor therapy.Drugs regulating tumor immune microenvironment or enhancing body immunity have indicated a novel perspective to treat tumors.Therefore,an increased number of scientists have been shifting their research focus to explore the immunity regulation effects of anti-tumor traditional medicine or natural products.In this review,we summarize the research progress of traditional medicines on tumor immunity regulation in 2020.Our findings suggest that more herbal medicine-derived phytochemicals and formulas were derived from traditional Chinese medicine,and more papers were published in comprehensive journals.Traditional medicine can comprehensively regulate the tumor immune microenvironment,including natural killer cells,dendritic cells,CD4+/CD8+T lymphocytes,regulatory T cells,myeloid-derived suppressor cells,tumor-associated macrophages,immunosuppressive factors,and immune checkpoints.In 2020,a greater number of research papers focused on active ingredients and formulas that regulate tumor-associated macrophages and immune checkpoints.Active ingredients such as flavonoids became a global hotspot in 2020.Certain natural products were also found to exert synergistic anti-tumor activity with immune checkpoint inhibitors,such as curcumin.However,a distinct lack of high-quality experimental and clinical studies remains a prevalent and challenging issue that hinders the further development of traditional medicine.

Celastrol activates caspase-3/GSDME-dependent pyroptosis in tumor cells by inducing endoplasmic reticulum stress Author links open overlay panel

Objective:To investigate the pyroptosis-inducing effects of celastrol on tumor cells and to explore the potential mechanisms involved,specifically focusing on the role of the caspase-3/gasdermin E(GSDME)signaling pathway and the impact of endoplasmic reticulum(ER)stress and autophagy.Methods: Necrostatin-1(Nec-1),lactate dehydrogenase release(LDH)assay,and Hoechst/propidium iodide(PI)double staining were employed to validate the mode of cell death.Western blot was used to detect the cleavage of GSDME and the expression of light chain 3(LC3)and BIP.Results: Celastrol induced cell swelling with large bubbles,which is consistent with the pyroptotic phenotype.Moreover,treatment with celastrol induced GSDME cleavage,indicating the activation of GSDME-mediated pyroptosis.GSDME knockout via CRISPR/Cas9 blocked the pyroptotic morphology of celastrol in HeLa cells.In addition,cleavage of GSDME was attenuated by a specific caspase-3 inhibitor in celastrol-treated cells,suggesting that GSDME activation was induced by caspase-3.Mechanistically,celastrol induced endoplasmic reticulum(ER)stress and autophagy in HeLa cells,and other ER stress inducers produced effects consistent with those of celastrol.Conclusion: These findings suggest that celastrol triggers caspase-3/GSDME-dependent pyroptosis via activation of ER stress,which may shed light on the potential antitumor clinical applications of celastrol.

Novel technologies and models for studying pharmacological activities of traditional Chinese medicine for promoting blood circulation and removing blood stasis

OBJECTIVE Our previous studies demonstrated that various ingredients from the traditional Chinese medicine(TCM)for promoting blood circulation and removing blood stasis,as exemplified by cryptotanshinone and salvianolic acid B,exerted striking effects on modulating angiogenesis and vascular permeability,which suggests that they may be effective in treating vascular leak-driven diseases(e.g.tumor,cerebral cavernous malformation and diabetic retinopathy).However,the lack of reliable and advanced technologies and models sets up difficult hurdles for better understanding the role of TCM for promoting blood circulation and removing blood stasis.To this end,this study is to outline numerous cutting-edge platforms that can be utilized for exploring the function of TCM for promoting blood circulation and removing blood stasis in vascular leak-driven diseases.METHODS Two-photon laser scanning fluorescence microscopy was used to observe the interactions between neutrophils and blood vessels in a real-time manner.Dynamic flow system was employed to mimic the in vivo behaviors of neutrophils.RIP1-Tag5 spontaneous pancreatic cancer model was used to study the function of tumor blood vessels.CCM2ECKO(deletion of CCM2 in endothelial cells)mice were employed to establish the cerebral cavernous malformation(CCM)animal model.Micro-computed tomography(micro-CT)was utilized to assess the CCM lesion.Müller cell-knockout mouse model was used to study the progression of diabetic retinopathy.Vascular permeability in this model was assessed by fluorescein angiography.RESULTS The interactions between neutrophils and endothelial cells involve a series of complicated processes,including rolling,adhesion,intraluminal crawling and transmigration,which were all monitored in vivo by two-photon laser scanning fluorescence microscopy in a real-time manner.Dynamic flow system was capable of recapitulating the biological behaviors of neutrophils in vitro.Tumor vascular function in particular vascular perfusion could be assessed in the RIP1-Tag5 spontaneous pancreatic cancer model.In terms of CCM studies,specific deletion of CCM2 in endothelial cells resulted in the initiation of CCM lesion.The size and number of CCM lesions could be visualized and quantified by micro-CT.Furthermore,the Müller cell-knockout mouse model was able to precisely reflect the clinical symptoms of diabetic retinopathy.Vascular leak could be monitored at different time points using fluorescein angiography.CONCLUSION An array of high technologies and animal models can be used in investigating the occurrence and progression of multiple vascular leak-driven diseases.The pre-clinical and clinical studies of TCM for promoting blood circulation and removing blood stasis provide fundamental support for the application of the above-mentioned platforms,with the purpose of uncovering the scientific basis of TCM for promoting blood circulation and removing blood stasis.
