Network pharmacology-based approach to investigate the mechanisms of Yiyi Fuzi Baijiang Powder in the treatment of malignant tumors

Objective:To systematically investigate the main active components,targets,target-related diseases and action mechanism of Yiyi Fuzi Baijiang powder(YFBP)of Zhang Zhongjing,a Chinese physician of Eastern Han Dynasty of China(3 century A.D.)using the method of network pharmacology.Methods:The active components of YFBP were identified from several databases(TCMSP,TCM Database@Taiwan and TCMID).The potential active compounds were screened based on oral bioavailability and drug-like index in the TCMSP database.DrugBank,TCMSP,and TCMID database searches were performed to predict target-related diseases.Biological functions and KEGG pathway outcomes of all potential targets were analyzed using the DAVID database.Results:A total of 24 active compounds of YFBP,133 related targets,and 305 potential related diseases were obtained.These results showed that YFBP may treat inflammation,pain,and cancer.The functional enrichment analysis indicated that YFBP probably exerts its therapeutic effects by regulating neuroactive ligand-receptor interactions,the TNF signaling pathway,and the PI3K-Akt signaling pathway.Conclusion:This study provides preliminary confirmation that YFBP has the great potentials to treat inflammation,pain,and tumors,which supports Zhang Zhongjing’s original intention to treat intestinal carbuncle with ancient prescription YFBP,but also provides a scientific basis for its treatment in the malignant tumors.

Dahuang Fuzi decoction reduces inflammation levels and alleviates intestinal mucosal barrier damage in septic rats

Objective:To investigate the protective effect of Dahuang Fuzi Decoction(DHFZD),a traditional Chinese prescription,at alleviating sepsis-induced inflammation and gut barrier damage in rats.Methods:Forty clean-grade male Sprague-Dawley rats were divided randomly into three groups:normal control group(NCG,n?10),model control group(MCG,n?15)and DHFZD-treated group(DHFZDG,n?15).NCG rats were sham operated on and used as the controls,whereas MCG and DHFZDG rats were used to replicate the rat sepsis model using cecal ligation and puncture(CLP).The DHFZDG rats received DHFZD by gavage(4.5 mg/g of body weight)2 h prior to CLP and after its successful induction,while the NCG and MCG rats received equivalent amounts of sterilized water by gavage.All rat groups were starved and had free access to water.At 24 h post-experimental set up,the mortality of rats in each group was recorded,and peritoneal inflammation assessment and pathological changes related to the intestinal mucosal injury index(IMII)in the surviving rats were evaluated.D-lactic acid,tumor necrosis factor(TNF)-a,interleukin(IL)-6 and IL-10 peripheral blood concentrations,along with secretory immunoglobulin A(sIgA)in the intestinal mucosa were evaluated by enzyme-linked immunosorbent assays.Gut microbes were detected using 16S rRNA gene sequencing.Results:DHFZD reduced sepsis-related mortality in the rats.Moreover,it alleviated peritoneal inflammation and pathological changes according to the IMII.DHFZD reduced serum procalcitonin,TNF-a and IL-6 concentrations,but not the IL-10 concentration.It also reduced serum D-lactic acid and increased sIgA concentrations in intestinal mucosa.Notably,DHFZDG restored gut microbiota diversity and regulated the decrease in Bacteroidetes induced by sepsis,compared with the MCG rats.Conclusion:DHFZDG may play a protective role in sepsis by alleviating sepsis-induced inflammation and gut barrier damage in rats.

Research progress on synergetic effects of Fuzi(Radix Aconiti Lateralis Preparata)and Tubeimu(Rhizoma Bolbostemmatis)/Gualou(Trichosanthes kirilowii Maxim)

The compatibility of Chinese herbs is the focus and the difficulty in traditional Chinese medicine research,and it has an important guiding role for clinical medicine.Some scholars believe that the Fuzi(Radix Aconiti Lateralis Preparata,FZ)compatibility with Tubeimu(Rhizoma Bolbostemmatis,TBM)/Gualou(Trichosanthes kirilowii Maxim,GL)does not meet the Chinese medicine theory of“eighteen incompatibilities”.However,this combination has been used many times in many clinical medications.This study reviewed the research progress of pharmacological effects of FZ,and FZ compatibility with TBM/GL,in order to correctly understand and apply the“eighteen incompatibilities”drugs,and provide a reference for further exploration of the combined application in clinical treatment.

Efficacy of Renshen(Radix Ginseng) plus Fuzi(Radix Aconiti Lateralis Preparata) on myocardial infarction by enhancing autophagy in rats

OBJECTIVE:To elucidate the protective effects of Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)on myocardial infarction(MI)through regulating myocardial autophagy.METHODS:Thirty-one male Sprague-Dawley rats were randomized into five groups(n=6 or 7 for each).After treatment for 3 weeks,electrocardiogram(ECG)and cardiac function were recorded.Hematoxylin and eosin(HE)staining was used to detect pathological changes in the heart.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum B-type brain natriuretic peptide(BNP),cardiac troponin T(c Tn T),tumor necrosis factor-α(TNF-α),and serum inflammatory cytokines.Metabolomic analysis was used to identify differential biomarkers of MI in rats.Immunohistochemistry and western blotting were used to detect BNP,cTnT,TNF-α,LC3B,Beclin-1,p62,and adenosine monophosphate activated protein kinase(AMPK)expression in cardiac tissue.RESULTS:Fuzi(Radix Aconiti Lateralis Preparata)alone or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)markedly ameliorated cardiac dysfunction and abnormal ECGs,demonstrated by decreases in the heart weight/body weight ratio,BNP,and c Tn T.Pro-inflammation cytokine interleukin(IL)-1αsignificantly decreased and anti-inflammatory cytokine IL-10 significantly increased in Renshen(Radix Ginseng)single or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)groups compared with the control group.HE results suggested that co-treatment produced a greater reduction in cardiomyocyte cross-sectional area than Renshen(Radix Ginseng)or Fuzi(Radix Aconiti Lateralis Preparata)alone.Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)reversed these changes to different degrees in MI rats.Furthermore,Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)down-regulated LC3 B,Beclin-1,and AMPK expression in cardiac tissue and upregulated p62 expression.CONCLUSIONS:Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)may have a greater effect on heart injury induced by MI in rats than Fuzi(Radix Aconiti Lateralis Preparata)treatment alone,and the underlying mechanism may be associated with the regulation of myocardial autophagy and anti-inflammation effects.These results provide fresh insight into the mechanism of co-treatment with Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)for MI.
