Taohong Siwu decoction(桃红四物汤)ameliorates atherosclerosis in rats possibly through toll-like receptor 4/myeloid differentiation primary response protein 88/nuclear factor-κB signal pathway

OBJECTIVE:To investigate the effect of Taohong Siwu decoction(桃红四物汤,TSD)on atherosclerosis in rats as well as investigate the underlying mechanism based on molecular docking.METHODS:Sixty healthy male Sprague-Dawley rats were randomly divided into 6 groups with 10 rats in each group:control group,model group,atorvastatin group(AT,2.0 mg/kg),and TSD groups(20,10,5 g/kg)after 7 d of acclimation.The model of atherosclerosis was successfully established except the control group by high fat diet(HFD)and vitamin D2.Biochemical analyzers were used to detect the levels of triglyceride(TG),total cholestero(TC),low density lipoprotein-cholesterol(LDLC)and high density lipid-cholesterol(HDL-C)in blood lipid.The levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and interleukin-1β(IL-1β)were determined by enzyme-linked immunosorbent assay.Sudan IV staining and Hematoxylin and eosin staining(HE staining)were performed to observe the pathological changes in aortic tissue.Molecular docking technology was used to predict the best matching between the main components of TSD and the target proteins.The expression of target proteins was further detected by quantitative real time polymerase chain reaction(q RTPCR)and Western blot analysis.RESULTS:The results showed that TSD restricted atherosclerosis development and decreased the inflammatory cytokines in plasma.Molecular docking results predicted that the main components of TSD showed a strong binding ability with toll-like receptor(TLR4),myeloid differentiation primary response protein 88(My D88),and nuclear factor kappa-B(NF-κB).The results of q RT-PCR and Western blot analysis showed that the m RNA and protein expressions of TLR4,My D88 and NF-κB p65 in the aorta were reduced in atorvastatin group and TSD group.CONCLUSIONS:TSD can ameliorate atherosclerosis in rats,and the underlying mechanism is supposed be related to the suppression of inflammatory response by regulating TLR4/My D88/NF-κB signal pathway.

Regulative effect of Taohong Siwu decoction(桃红四物汤) on extracellular matrix of endometrium in drug-induced abortion

OBJECTIVE: To explore the effects of Taohong Siwu decoction(桃红四物汤, THSWD) on the extracellular matrix of endometrium in rats following drug-induced abortion.METHODS: Thirty-six pregnant female rats were administered mifepristone and misoprostol to induce abortion, and amounts of uterine bleeding were recorded. Pathological damage and collagen accumulation were detected by hematoxylin-eosin staining and Masson’s trichrome staining in uterus, respectively. Myeloperoxidase was evaluated by immunohistochemistry.The expression levels of fibronectin, laminin, matrix metalloproteinase 9(MMP-9), and tissue inhibitor of metalloproteinase 1(TIMP-1) were quantified using western blotting.RESULTS: THSWD could promote endometrial protection in rats following drug-induced abortion.The contents of cellulose and myeloperoxidase were significantly decreased in uterine tissue of THSWD-treated groups. Moreover, THSWD significantly decreased the expression levels of fibronectin, laminin, and TIMP-1. THSWD also significantly increased MMP-9 expression and the MMP-9/TIMP-1 ratio.CONCLUSION: THSWD plays a critical role in endometrial protection by reducing extracellular matrix deposition and uterine fibrosis. These effects may have been achieved by increasing MMP-9, reducing TIMP-1, and/or altering the ratio of MMP-9/TIMP-1.

Objective: To observe the clinical effect of Modified Taohong Siwu Decoction (MTSD) in treating pediatric intractable nephropathy (PIN). Methods: Ninety-five patients with PIN were divided into 2 groups at random. The 60 patients in the treated group were treated with MTSD and the 35 patients in the control group were treated with heparin. The clinical therapeutic effect and levels of thromboxane B2 (TXB2) and 6-keto-prostacyclin F1α (6-keto-PGF1α) before and after treatment were observed. Results: The total effective rate in the treated group was 81.7%, which was similar to that in the control group (80.0%, P>0.05). The levels of TXB2 and TXB2/6-keto-PGF1α ratio were higher in both groups of the patients as compared with those of the healthy control (P<0.01). After treatment, the two criteria were significantly improved in the two treated groups, as compared with those before treatment, the difference was significant (P<0.01), while in comparison between the MTSD treated group and the control group, no significant difference was found (P>0.05). Conclusion: MTSD has good effect in treating PIN, it could improve the metabolic unbalance of thromboxane and prostacyclin.

Chinese Medicines and Bioactive Compounds for the Treatment of Stroke

Stroke is an important cause of mortality and morbidity worldwide but effective therapeutic strategy for the prevention of brain injury in patients with cerebral ischemia is lacking. Although tissue plasminogen activator has been used to treat stroke patients, this therapeutic strategy is confronted with ill side effects and is limited to patients within 3 h of a stroke. Due to the complexity of the events and the disappointing results from single agent trials, the combination of thrombolytic therapy and effective neural protection therapy may be an alternative strategy for patients with cerebral ischemia. Chinese medicine （CM） is the most widely practiced form of herbalism worldwide, as it is a sophisticated system of medical theory and practice that is specifically different from Western medicine. Most traditional therapeutic formulations consist of a combination of several drugs. The combination of multiple drugs is thought to maximize therapeutic efficacy by facilitating synergistic actionsand preventing possible adverse effects while at the same time marking at multiple targets. CM has been labeled in ancient medicine systems as a treatment for various diseases associated with stroke. This review summarizes various CMs, bioactive compounds and their effects on cerebral ischemia.
