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.

Clinical Observation on Influence of Chinese Medicines for Promoting Blood Circulation to Remove Blood Stasis on FIB and DD in Plasma of Patients with Cerebral Thrombosis

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.

Revealing the material basis of MMP9-mediated activating blood and removing blood stasis drugs on Danshen-Ligusticum chuanxiong anti- vascular effect

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.

基于“成骨-成血管耦联”理论探讨中医药防治激素性股骨头坏死的科学内涵

激素性股骨头坏死(steroid-induced necrosis of the femoral head, SNOFH)是骨科常见难治性疾病,又被视为“不死癌症”,若不及时干预将导致患者面临人工全髋关节置换术的风险。近些年研究证实,“成骨-成血管耦联”途径研究SNOFH发生发展的机制具有重要意义。SNOFH中医病机责之于脾肾亏虚为本,瘀血为病,痰阻为渐,毒聚为损。“成骨-成血管耦联”机制与“瘀去-新生-骨合”中医理论存在高度契合性。越来越多的临床证据表明中医药治疗SNOFH不仅具有疗效显著、不良反应小、价格低廉等优势,还能提高患者生存质量,为促进股骨头血管重建与再生以及股骨头坏死骨修复等发挥重要作用。基于“瘀去-新生-骨合”理论,临床上多采用补肾活血类中药及中药复方用于SNOFH防治,运用“成骨”之健脾补肾药,“成血管”之活血化瘀药,祛除“抑制因素”之化痰药、祛湿药,有步骤、有层次的治疗SNOFH取得显著效果。因此,从“成骨-成血管耦联”角度探讨SNOFH中医药干预的科学内涵已成为当今研究新热点,能够为后续SNOFH的防治研究和新药研发提供理论参考和借鉴。

舌诊在慢性肝病中的应用刍议

舌诊作为中医特色诊法之一,在肝病的诊治与预防中具有重要意义。慢性肝病患者在不同的病理阶段有不同的舌象改变。舌色可反映肝病轻重缓急,如缓解期多见淡红舌,发作期多见红绛舌,而严重肝病多见青紫舌;舌形可反映肝病形气神,其中长条舌、圆柱舌是慢性肝病的常见舌形,舌缘肿大或者肝积舌多代表慢性肝病中的占位性病变;舌苔与肝病轻重及疾病预后有关,还可辅助诊断慢性肝病的细菌感染情况。此外,舌象在慢性肝病的临床用药指导中也具有重要意义,可多方面、多角度指导临床。

活血化瘀法在慢性原发免疫性血小板减少症辨治中的循证探索

目的:基于临床和中西医理论的整合,探索中医活血化瘀法在慢性原发免疫性血小板减少症(Primary Immune Thrombocytopenia,ITP)治疗中的临床应用循证依据。方法:结合临床总结分析中西医对ITP的病机认知,结合临床辨证和研究结果进行综合比照分析。结果:①慢性ITP虽然是以出血为主要表现的疾病,但是临床中仍然有发生血栓的现象,即出血与血栓的发生并存;②由中医学理论和临床辨证对ITP出血与瘀血状态的认识可知两者互为影响,验证了“离经止血,虽为清血,亦为瘀血”“瘀血不去,新血不生”的理论;③ITP的发生、发展过程中病机演化对瘀血形成的认识,提示了“久病多瘀”的证据;④中医药辨证论治的过程中,不失时机地选择应用活血化瘀法,不仅有效地治疗了ITP的出血症状,而且通过活血化瘀法还能够预防血栓的发生,提供了临床疗效证据。结论:基于临床疗效和ITP病机、病程的综合分析,中医活血化瘀法在慢性甚至是难治性ITP的治疗中不仅可以改善临床症状,还能够预防血栓的发生,为临床广泛应用提供很好的循证依据。部分患者的血小板水平也有提升。至于提升血小板的机制还有待于进一步的临床研究。

活血化瘀类中药饮片与口服抗凝血药联合应用的出血风险研究

目的:探讨联合应用活血化瘀类中药饮片与口服抗凝血药治疗疾病的出血风险。方法:回顾性研究2022年该院服用口服抗凝血药和活血化瘀类中药饮片的住院患者158例,根据是否联合应用活血化瘀类中药饮片分为联合组(80例)和对照组(78例)。对照组患者使用的口服抗凝血药包括华法林、利伐沙班、达比加群酯;联合组患者联合应用的活血化瘀类中药饮片包括丹参、川芎、牛膝等。观察两组患者的凝血功能相关指标如凝血酶原时间-国际标准化比值(PT-INR)、纤维蛋白原(FIB)、D-二聚体(D-D)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)和出血事件发生率等。结果:联合组与对照组患者PT-INR、FIB、D-D、APTT和TT的差异均无统计学意义(P>0.05);联合组患者的出血事件发生率为66.25%(53/80),高于对照组的42.31%(33/78),差异有统计学意义(P<0.05)。结论:患者联合应用活血化瘀类中药饮片与口服抗凝血药后,虽然相关凝血指标并未出现明显变化,但是出血事件发生率显著升高。临床用药时,需重点关注含有丹参、川芎、牛膝和红花等的活血化瘀类中药饮片或中药复方制剂与口服抗凝血药联合应用会增加出血的风险。本研究为中西药相互作用研究提供了一定的借鉴。

柳国斌教授从“寒凝血瘀”论治血栓闭塞性脉管炎的经验

本文对柳国斌教授治疗血栓闭塞性脉管炎的学术思想进行总结。柳教授提出阳虚寒凝是血栓闭塞性脉管炎的始动病机,而后形成瘀血、脉络闭阻等病理环节,故将本病的病机概括为“寒凝经脉,瘀血阻络”,其提出以“温经散寒,活血通络”为治疗法则,遣方用药注重扶阳,认为机体的阳气充足后,气血得以运行顺畅,瘀血等病理因素随之消散。柳教授强调只有抓住病机才能抓住治疗的关键,在复杂的疾病中找出矛盾所在,才能取得良效。现将柳教授临证经验总结如下,并附验案1则,为治疗血栓闭塞性脉管炎提供思路。
