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.

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.

Studies on the Degranulation of RBL-2H3 Cells Induced by Traditional Chinese Medicine Injections

Aims: To study RBL-2H3 cell degranulation phenomena induced by some TCMIs through cell morphological and ultra-structural observation, released enzyme activity and establish RBL-2H3 cell degranulation test indicated by β- hexosaminidase activity as a method to evaluate TCMIs at nonclinical stage. Methods: RBL-2H3 cells were used to study the degranulation by co-culture with positive control C48/80 and some TCMIs through morphological and ultra-structure observation, β-hexosaminidase activity detection. RBL-2H3 cell degranulation test was established to detect β-hexosaminidase activity caused by 17 kinds of TCMIs and their ingredients. The cytotoxicity effect of some TCMIs on both RBL 2H3 and BRL cells was measured by CCK-8 assay. Results: Toluidine blue staining and ultra-structure of electronic microscope observation of treated RBL-2H3 cells showed degranulation morphologically. Detection of β-hexosaminidase activity in the supernatant of treated cells showed some TCMIs had elevated enzyme release rates. Further analysis of the ingredients and compound in Tanreqing Injection and Shengmai Injection showed Scutellaria baicalensis Georgi in Tanreqing Injection, Red ginseng and Fructus Schisandrae Chinensis in Shengmai Injection were responsible to the degranulation of RBL-2H3 cells. Osmotic pressures and pH influenced RBL-2H3 degranulation. High Osmotic pressure of Tanreqing Injection and low pH of chlorogenic acid at 2.5 and 5.0 mmol/L congcentration might be responsible to high β-hexosaminidase activity. Most of the TCMIs inducing degranulation had cytotoxicity effect for both RBL-2H3 and BRL cells, but some TCMIs inducing degranulation had no cytotoxicity effect. Conclusion: Some TCMIs can induce degranulation of RBL-2H3 cells;RBL-2H3 cell degranulation test can be used in non-clinical stage to detect the risk causing anaphylactoid reactions. Osmotic pressures and pH influenced RBL-2H3 degranulation, and they should be measured before testing. The mechanism of degranulation caused by some TCMIs is cytotoxic, and some are non-cytotoxic and may be through exicytosis.

Treatment and prevention of diabetes complicated with non-alcoholic fatty liver disease by integrated traditional Chinese and Western medicine

Today’s social economy and science and technology levels are developing rapidly.Type 2 diabetes mellitus(T2DM)is increasing in incidence,and T2DM promotes non-alcoholic fatty liver disease(NAFLD)through some mechanisms.The pathogenesis of T2DM and NAFLD is interconnected,interacted with,and promoted.While increasing the economic burden on patients,it also affects the quality and life of patients themselves.In the world,the current treatment methods include exercise and diet control,drugs(including sugar reduction,lipid-lowering drugs,etc.),weight loss surgery,etc.,but currently,researching drugs can only control the progress of the disease.At present,there is no drug for T2DM combined with NAFLD treatment.Therefore,it is necessary to find and study effective drugs for NAFLD.Based on the principle of“syndrome differentiation,”traditional Chinese medicine(TCM)played an important role in treating this disease.The theory of TCM believes that the cause of NAFLD is mostly diet disorders and imbalances in daily life,leading to liver Qi stagnation,spleen dysfunction,and liver and kidney deficiency,producing phlegm and stasis.During the treatment process,we must pay attention to the goal of phlegm turbidity,but also pay attention to the source of phlegm turbidity,strengthen the spleen and stomach,nourish the liver and kidney,and restore the physiological function of the body.The ingredients of Chinese medicine extracts have the effects of antagonist oxidation stress,protecting liver cells,improving fibrous soluble systems,and promoting lipid metabolism,thereby reducing inflammatory factors to release damage to liver cells.By combining the diagnosis of TCM syndromes with Western medical disease diagnosis,the model of disease diagnosis combined with syndrome differentiation can compensate for some of the limitations of TCM’s sole reliance on syndrome differentiation,allowing for a better grasp of the disease.In treatment,a dual approach using traditional Chinese and Western medicine can enhance efficacy and reduce toxicity,leveraging both complementary strengths.Chinese medicine explains its treatment of NAFLD from a macro and micro level,providing a safer and more effective method for treating the disease.

Efficacy of traditional Chinese medicine on shortening the negative conversion time of SARS-CoV-2 ribonucleic acid in patients with mild COVID-19:a retrospective cohort study

BackgroundThe holistic view of the‘The unity of man and nature’promotes the development and application of traditional Chinese medicine(TCM).Despite the absence of modern pharmacological therapies with robust efficacy against coronavirus disease 2019(COVID-19),TCM has exhibited potential utility for treating the disease in clinical practice.MethodsA retrospective cohort study was conducted to investigate the therapeutic effect of TCM treatment intensity(TCMTI)in patients with mild COVID-19.A total of 6120 laboratory-confirmed patients with mild COVID-19 were recruited from temporary isolation facilities.The primary outcome measure was severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)ribonucleic acid conversion time.In addition,restricted cubic spline models were employed to elucidate nonlinear relationships.ResultsThe median age(range)of the study participants was 43.0(2.0–75.0)years,with a median hospitalization duration of 9.7(4.1–22.5)days.The median time for achieving SARS-CoV-2 ribonucleic acid negativity was 6.67 days.The restricted cubic spline models revealed a remarkable nonlinear association between TCMTI and the time-to-ribonucleic acid negativity.After adjusting for potential confounders,the high TCMTI group exhibited a markedly shorter median time to SARS-CoV-2 ribonucleic acid negativity and reduced hospitalization duration(P<0.001)than the low TCMTI group.Moreover,the mean time to achieve SARS-CoV-2 ribonucleic acid negativity was shortened by 1.909 days(P<0.001)in the high-TCMTI group compared to the low-TCMTI group.ConclusionThis study suggests that early initiation and intensified use of TCM may accelerate the time required to achieve SARS-CoV-2 ribonucleic acid negativity in patients with COVID-19,bearing considerable implications for public health.

Common traditional Chinese medicine therapies for diarrhea-predominant irritable bowel syndrome: An overview of systematic reviews

Objective: To critically evaluate and summarize the methodological quality of systematic reviews(SRs)and present objective and important outcomes on the effectiveness of traditional Chinese medicine(TCM) therapies, including Chinese herbal medicine(CHM), acupuncture, and moxibustion, for diarrheapredominant irritable bowel syndrome(IBS-D).Methods: We conducted a comprehensive literature search for SRs in 7 databases until April 16, 2022.Two reviewers independently extracted data and assessed the methodological quality of the reviews according to the Assessing the Methodological Quality of Systematic Reviews 2(AMSTAR-2), the Risk of Bias in Systematic reviews(ROBIS) tool, and the Preferred Reporting Item for Systematic Review and Meta-analysis(PRISMA) statement. The Grading of Recommendations, Assessment, Development, and Evaluation(GRADE) was used to rate the quality of evidence.Results: IBS-D patients included in 12 reviews were diagnosed in accordance with the Rome criteria, 9 reviews focused on CHM, 2 articles observed moxibustion and heat-sensitive moxibustion, 1 article studied acupuncture and CHM. The outcomes of the SRs were the effectiveness rate, the total effectiveness rate,global symptom improvement, and adverse effects. Based on AMSTAR-2, which measures the quality of methodology, all of the included studies were of low or critically low quality. According to the ROBIS tool, 10 SRs(83.33%) had a high risk of bias. With the PRISMA checklist, only 3 SRs reached over 90% compliance.Based on GRADE, most evidence was of low quality, and there was a moderate quality of evidence that the effectiveness rate of modified-Tongxie Yaofang was superior to Western medicine in the treatment of IBS-D.Conclusion: Given the suboptimal reporting and methodological quality of existing SRs, more studies are needed to clarify whether TCM therapies are more effective or safe than pharmacological medicine.Future studies should combine evidence-based medicine with TCM research according to the characteristics of TCM.

Traditional Chinese medicine:an important broad-spectrum anti-coronavirus treatment strategy on COVID-19 background?

Coronaviruses exist widely in nature,can cause cross-species transmission,and pose serious threats to human and animal health.Over the past 20 years,coronaviruses have led to three major epidemics that have caused global panic,including severe acute respiratory syndrome,Middle East respiratory syndrome,and coronavirus disease-19.At present,coronavirus disease 19 not only spreads rapidly,but also mutates easily to escape host immune response,becoming more pathogenic.At present,there are no effective specific therapeutic drugs or vaccines.Drugs targeting severe acute respiratory syndrome coronavirus 2 and the host cell defense system that have been developed based on the structure and replication cycle of coronaviruses have a certain broad-spectrum antiviral effect;however,their efficacy still needs to be demonstrated in further clinical trials.Traditional Chinese medicine has an indispensable role in the ongoing response to coronavirus disease-19.Anti-virus treatment with traditional Chinese medicine has advantages such as broad-spectrum application,low toxicity and side effects,low susceptibility to drug resistance,and overall comprehensive regulation.Therefore,researches on effective components and mechanisms of action of the anti-viral effects of traditional Chinese medicine have increasingly gained attention.The present paper examines coronaviruses,specifically summarizing the genomes,replication mechanisms,and mutant strains.Afterward,the therapeutic effects and mechanisms of action of modern broad-spectrum anti-coronavirus drugs and traditional Chinese medicine are summarized.By considering the virus and the targets in the host comprehensively,in addition to the beneficial multi-target and multi-path antiviral effects of traditional Chinese medicines,this paper could guide the development of treatment strategies for broad-spectrum anti-coronavirus traditional Chinese medicines,and could facilitate the modernization and globalization of traditional Chinese medicine.
