Research Progress and Prospects on the Anti-liver Fibrosis,Blood Circulation-promoting and Stasis-resolving Effects of Curcuma kwangsiensis Based on W-P Bodies

Liver fibrosis is a necessary stage in the progression of chronic liver disease to cirrhosis.So far,no satisfactory drugs have been found to intervene in liver fibrosis.Liver microcirculation disorders are one of the important pathogenesis of chronic liver disease,and hepatic sinusoidal endothelial cells(HSECs)are the main cells that constitute the liver microcirculation barrier.In clinical practice,W-P bodies have been detected in HSECs of most patients with liver fibrosis.W-P bodies serve as a site for the synthesis and storage of vW factors,ET-1 and other cytokines that promote liver fibrosis.They can disrupt the structure and function of HSECs,cause liver microcirculation disorders,and exacerbate the progression of liver fibrosis.Previous studies have found that the Guangxi specialty ethnic medicine,C.kwangsiensis S.G.Lee et C.F.Liang,has definite effects in promoting blood circulation,resolving blood stasis,and resisting liver fibrosis.Based on this,a further research idea has been derived,stating that the blood circulation-promoting,blood stasis-resolving,and anti-liver fibrosis effects of C.kwangsiensis are produced by affecting the formation of W-P bodies,the synthesis and storage of contents in W-P bodies,and intervening in their exocytosis capacity.

Clinical and experimental study of effect of Raondix Salviae Militiorrhiza and other blood activating and stasis eliminating Chinese herbs on hemodynamics of portal hypertension

AIM To study the effects of Radix Salviae Militiorrhiza (RSM), other blood-activating and stasis-eliminating Chinese herbs on hemodynamics of portal hypertension.METHODS Portal pressure of cirrhotic dogs after chronic common bile duct ligation was measured directly; portal blood flow in patients with liver cirrhosis were detected by ultrasound Doppler.RESULTS After administration of RSM and Radix Angelicae Sinensis (RAS) by intravenous infusion in cirrhosis dogs, the portal venous pressure (Ppv), wedge hepatic venous pressure (WHVP), hepatic venous pressure gradient (HVPG), were significantly decreased (P＜0.05-0.01), but the mean arterial pressure (MAP), and the heart rate (HR) remained unchanged. When nifedipine was used, Ppv, WHVP, MAP and HR were significantly decreased (P＜0.05), and the MVPG unchanged (P＞0.05). After administration of RSM, RSM+nifedipine and RSM+Hirudin+Nifedpin for 10-12 weeks, the diameter of portal vein (Dpv), spleen vein (Dsv), the portal venous flow (Qpv) and splenic venous flow (Qsv) in patients with hepatic cirrhosis were significantly lowered (P＜0.05-0.01), and the effect of RAS was weaker.CONCLUSIONS The efficacy of decreasing Ppv by Chinese herbs-RSM, RAS, etc. as compared with nifedipine, demonstrated that the Chinese herbs were slower in action than that of nifedipine, but more long-lasting and without side effects. Hence, long-term administration of Chinese herbs, would be more beneficial.

to study the influence of Chinese medicines for promoting blood circulation to remove blood stasis on fibrinogen(FIB)and D-dimer(DD)in plasma of patients with cerebral thrombosis. Method:73 inpatients with acute cerebral thrombosis were randomly divided into a control group of 34 cases and a treatment group of 39 cases.The content of FIB and DD in plasma was detected before treatment and on the 7th and 14th days after treatment.Result:FIB content in plasma after treatment was lower than that before treatment in the control group(P<0.01)and more remarkable in the treatment group(P<0.001).There was an obvious difference in DD content before and after treatment in both groups.DD content on the 7th and 14th days after treatment in the treatment group was obviously higher than that in the control group(P<0.01 and P<0.05 respectively). Conclusion:Chinese medicines for promoting blood circulation to remove blood stasis can reduce the FIB content in plasma of patients with cerebral thrombosis,raise the DD content in plasma, cause the peak of DD content appear earlier and obviously improve hypercoagulability of blood in patients with cerebral thrombosis.

Research Progress and Research Ideas on Anti-hepatic Fibrosis and Promoting Blood Circulation and Removing Blood Stasis of the National Drug Plumbapin Based on TLR4 Signal Pathway

Hepatic fibrosis is a reversible pathological phenomenon in the early and middle stages,but but no satisfactory intervention drugs have been available so far.Recent studies have suggested that microcirculation disturbance of liver is one of the important pathogenesis of chronic liver disease,the improvement of microcirculation is beneficial to the recovery of liver function and the delay of liver fibrosis.Hepatic stellate cells are the core cells of hepatic fibrosis,and also the most critical cells that affect the microcirculation of the liver.While TLR4/MyD88/NF-κB and TLR4/MyD88/MAPKs which are based on the action of hepatic stellate cells are two pathways that have very important influence on the inflammatory response of liver,the proliferation and apoptosis of hepatic stellate cells,and the secretion of fibrogenic cytokines.It was found that Plumbapin,the active ingredient of Guangxi specialty ethnic medicine,has the definite effect of promoting blood circulation and removing blood stasis and anti-hepatic fibrosis,but its mechanism is not clear.In this study,the research progress of the above problems was reviewed,and further research ideas were derived as follows:the pharmacological effect of Plumbapin on anti-hepatic fibrosis,promoting blood circulation and removing stasis was based on the influence of TLR4/MyD88/NF-κB and MAPKs signal pathway.

Objective:Reveal the material basis and mechanism of angiogenesis effect of Danshen-chuanxiong herb-partners.Methods:The effective components of Danshen and chuanxiong were searched in the TCM System Pharmacology Database(TCMSP),and the drug targets were searched in the Swiss Target Prediction database;in the Disease-Gene Database(DisGeNET))Search for angiogenesis-promoting and inhibiting angiogenesis targets;use the protein interaction database(STRING)database and Cytoscape software to analyze the network core targets;use the DAVID database to enrich the drug-disease target intersection for GO and KEGG;RT-qPCR experiments verified the effect of luteolin on MMP9 gene expression;in vitro tube formation experiments analyzed the effect of luteolin on endothelial cell neovascularization.Results:After analysis,it is concluded that Danshen has 10 active ingredients and 50 angiogenesis targets;Chuanxiong has 2 active ingredients and 4 angiogenesis targets.The intersection of drug-taking targets yielded 9 targets,including AR,PARP1,MMP9,MMP2,MMP12,AKR1B10,ABCC1,CDK6,and STAT3.After analyzing the active ingredient-target network graph of Danshen/Chuanxiong,it was concluded that luteolin is the key chemical ingredient.After protein interaction(PPI)analysis,the results showed that MMP9 is the core target.The KEGG pathway is mainly enriched in 5 signaling pathways,the most important pathway is cancer-related pathways.There are 22 main biological processes of GO,which mainly involve collagen catabolism,protein extracellular matrix,metal endopeptidase activity,etc.The preliminary analysis of tubule formation experiment shows that luteolin inhibits angiogenesis and down-regulates the expression of MMP9 gene.Conclusion:Luteolin,the key chemical component of the Danshen-Ligusticum chuanxiong drug pair,inhibits angiogenesis by regulating the MMP9 target,and develops the reverse regulation of angiogenesis for the traditional Chinese medicine for promoting blood circulation and removing blood stasis on the basis of the known treatment of ischemic diseases.Provide a new perspective and theoretical basis for the use of Danshen and Chuanxiong medicine in clinical cancer patients.Reveal the material basis and mechanism of angiogenesis effect of Danshen-chuanxiong herb-partners.

Study on the Protective Effects of Compound Blood-activating Soup on Bone Marrow Hematopoietic Cells in Acute Radiation Injured Mice

After irradiation with 8 Gy 60Coγ-ray,mice were immediaterly given intraperitoneal injection of 200 mg 100 % compound blood-activating soup twice a day. On the 3rd and 7th day, the P53 gene expression of bone marrow hematopoietic cells in Chinese drug group was found to be higher than that in normal group, and it was also significantly higher than that in control group. The expression level of GADD153 gene which was not expressed in normal group was much lower in Chinese drug group than that in control group. On the 7th day after irradiation, the P53 and GADD153 gene expression levels of splenic mononuclear cells were consistent with those of bone marrow hematopoietic cells both in Chinese drug group and control group. On the 3rd and 7th day, the bone marrow hematopoietic tissue volume in Chinese drug group was higher than that in control group, with no difference found between the two groups. While on the 14th day, the difference became significant (P＜0. 01). The results showed that commonly used blood-activating and stasis-eliminating drugs may strengthen .the viability of hematopoietic cells and promote the rehabilitation of hematopoiesis by inducing wt-P53 expression to block the bone marrow hematopoietic cells in G1 phase, during which DNA could be repaired.
