Tumors were excised on day 15 and analyzed. Tumor microvessel density(MVD)was assessed by immunohistochemical staining of CD34;and expression of vascular endothelial cell growth factor(VEGF), the mitogen-activated protein kinases p38 mitogen-activated protein kinase(MAPK), extracellular signal-regulated kinases 1 and 2(ERK1/2), and Jun N-terminal kinase(JNK)and their phosphorylated forms were assessed by Western blotting.RESULTS: Treatment with cisplatin caused a significant loss of body weight compared with controls,whereas Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) extract combinations had no effect. Extracts from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) significantly decreased tumor weight and tumor MVD compared with controls,and at the 3∶1 treatment group had similar efficacy to cisplatin in reducing MVD. Tumors from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) treatments also showed decreased p38 MAPK, p-p38 MAPK, ERK1/2, p-ERK1/2,JNK, and p-JNK expression compared with the control group(all P < 0.01). VEGF protein expression was significantly reduced in the 2∶1 and 3∶1 treatment groups compared with the control group(P < 0.01).CONCLUSION: Extracts from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) hindered LLC growth in the xenograft mouse model, possibly via inhibition of 展开更多

Methods： Blood was collected from volunteers. Effects of the prepared water extracts of herbs on platelet aggregation were monitored on a Packs-4 aggregometer. The fluorescence intensity of water extracts of Caulis Spatholobi, Flos Carthami and Rhizoma Curcumae on the expression of P-selectin in human platelets of healthy persons was measured with flow cytometry. Results： Out of several herbs investigated, Flos Carthami and Rhizoma Curcumae potently inhibited platelet aggregation after incubation with platelet-rich plasma （PRP） for 15 min. Caulis Spatholobi, Flos Carthami and Rhizoma Curcumae inhibited adenosine-5＇-diphosphate （ADP） or platelet activating factor （PAF）-induced platelet aggregation in PRP in a dose-dependent manner. In contrast to Flos Carthami and Rhizoma Curcumae, Caulis Spatholobi could not inhibit thrombin-induced platelet aggregation. Despite its inability to inhibit thrombin-induced platelet aggregation in PRP, Caulis Spatholobi had a greater anti-aggregating activity in PRP induced by ADP or PAF. Caulis Spatholobi and Flos Carthami showed significant inhibitory effects on the expression of P-selectin. Conclusions： Caulis Spatholobi, Flos Carthami and Rhizoma Curcumae have potent anti-platelet properties, and their inhibitory actions are mediated via different mechanisms. Caulis Spatholobi inhibited ADP-induced platelet aggregation but not by thrombin, indicating that its mechanism of action might be independent of the thromboxane pathway. The effect of Caulis Spatholobi and Flos Carthami were associated with suppressing the expression of P-selectin.展开更多

Ultrasonic extraction and GC-MS methods were developed for the simultaneous determination of five sesquiterpenes, namely, α-pinene, β-elemene, curcumol, germacrone and curdione, in Ezhu and Yunjin. Good linearity （r〉0.999） and high inter-day precision were observed over the investigated concentration ranges. The validated method was successfully used for the simultaneous determination of five sesquiterpenes in Ezhu and Yujin. The quantitative method can be effectively used to evaluate and monitor the quality of Chinese curcuma in clinical use.展开更多

As a result, researchers are seeking other methods or agents based on previous studies. Among the various prospective approaches, vascular protection might be the key for development of therapeutic agents for stroke and for improvements in the efficacy and safety of conventional therapies. Traditional medicines in Asian countries are based on clinical experiences and literature accumulated over thousands of years. To date, many studies have used traditional herbal medicines to prove or develop new agents based on stroke treatments mentioned in traditional medicinal theory or other clinical data. In the current review, we describe the vascular factors related to ischemic brain damage and the herbal medicines that impact these factors, including Salviae Miltiorrhizae Radix, Notoginseng Radix, and Curcumae Rhizoma, based on scientific reports and traditional medical theory. Further, we point out the problems associated with herbal medicines in stroke research and propose better methodologies to address these problems.展开更多

MTS assay was applied to analyze the effect of the component formula ofHuangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) on A549 cells viability in various uniform design groups. A549 cells with exponential growth in routine culture were exposed to Co Cl_2(200 μmol/L) to mimic hypoxic conditions. Group 0 was treated with RPMI-1640, the group Co Cl_2 was treated with Co Cl_2(200 μmol/L),the group DDP + Co Cl_2 was treated with 4 mg/L Cisplatin injection(DDP) + Co Cl_2(200 μmol/L), and the drug group was treated with various dose of E(0.5 E, 1 E, 2 E) + Co Cl_2(200 μmol/L). All groups were cultured for 24 h. Cell apoptosis was measured by Annexin V-FITC/propidium iodide double staining and flow cytometry. Western blot assay and quantitative real-time polymerase chain reaction(q RT-PCR) were employed to detect the protein and m RNA expression of B-celllymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax) and cysteinyl aspartate specific proteinase-3(caspase-3).RESULTS: The E obtained by the uniform design was comprise of 200 mg/L Astragalus polysaccharide(X1) and 32 mg/L Curcumin(X3). Group DDP+Co Cl_2, group 1 E + Co Cl_2 and group 2 E + Co Cl_2 promoted the apoptosis of A549 cells(P < 0.05). Group1 E + Co Cl_2 and group 2 E + Co Cl_2 had no statistically significant differences compared with the group DDP + Co Cl_2(P > 0.05). Compared with group 0, various doses of E + Co Cl_2 could up-regulate the expression of Bax and caspase-3 and down-regulate the expression of Bcl-2 at protein and m RNA levels(P < 0.05).CONCLUSION: Astragalus polysaccharide and Curcumin was the optimal combination 展开更多

Materials and Methods: Network analysis and pharmacological evaluation were performed to explore the protective role of CR to treat CIRI. The potential target genes of the active components and CIRI were identified using SwissTarget Prediction, Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine, GeneCards, and Online Mendelian Inheritance in Man. Furthermore, network analysis was performed using Cytoscape software.Gene ontology analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed using the R software. In vivo experiments were performed using the water extract of CR(WECR) on PC12 cells induced by hypoxia/reoxygenation(H/R) to simulate ischemia/reperfusion injury. Results: The results exhibited that 21 active compounds identified in CR were associated with 73 targets of CIRI. Functional analysis showed that multiple pathways, including response to stress, regulation of apoptotic process, and hypoxia-inducible factor 1 signaling pathway, were significantly enriched. In addition, STAT3, IL4, HIFIA, and CTNNB1 were predicted to be the most important genes among the 36 hub genes. Furthermore, WECR treatment significantly improved PC12 cell injury and decreased apoptosis levels in cells induced by H/R, with malondialdehyde contents reduced and superoxide dismutase or glutathione peroxidase levels increased. Conclusions: Network analysis and pharmacological evaluation of CR could provide valuable directions for further research on CR and improve comprehension of CIRI.展开更多
