RESUMO
Coronary heart disease (CHD) and stroke are the most well-known cardiovascular diseases, which share many common pathological basis. Yindan Xinnaotong soft capsule (YDXNT) is a commonly used Chinese patent medicine in the treatment of stroke and CHD. However, its action of mechanism of co-treatment for stroke and CHD is still unclear. The aim of this study was to explore the common mechanism of YDXNT in co-treatment of CHD and stroke using network pharmacology, experimental verification and molecular docking. An integrated literature mining and databases of IPA, ETCM, HERB, Swiss Target Prediction, OMIM and GeneCards were used to screen and predict active ingredients and potential targets of YDXNT in co-treatment of CHD and stroke. The protein-protein interaction network, GO analysis and pathway analysis were analyzed by IPA software. The effect of YDXNT on core targets was verified by immunofluorescence. UPLC-QTOF/MS and molecular docking were used to screen and predict the main active constituents of YDXNT and their interactions with core targets. A total of 151 potential targets are predicted for YDXNT in co-treatment of CHD and stroke. Hypoxia-inducible factor-1α (HIF1α)-matrix metalloproteinase-9 (MMP9)-mediated HIF1α signaling pathway serves as one of the common mechanisms. YDXNT could reduce the increase of mitochondrial fluorescence intensity and the protein expression of HIF1α and MMP9 in HL-1 and HA induced by oxygen and glucose deprivation/reperfusion (OGD/R) in a dose-dependent manner. Baicalin may be the material basis for treating stroke and CHD with YDXNT. In conclusion, the HIF1α signaling pathway is one of the common key mechanisms of YDXNT in the co-treatment of stroke and CHD. The study provides support and basis for the in-depth scientific connotation of the traditional Chinese medicine theory of "same treatment to different diseases".
RESUMO
Objective:To investigate the anticancer activity and mechanism of aconitine on cell proliferation,invasion and migration of hepatoma carcinoma cell(HCC).Methods:The effect of aconitine at different concentrations on proliferation was calculated by MTT assay.The effects of aconitine on invasion and migration of HCC were measured by Transwell and wound healing assay.Western blot was employed to detect the protein levels of P38MAPK signaling pathway-related proteins.Results:The concentrations of 5,10,20 μg/ml were selected according to the results of pre-experiment.Aconitine(10,20 μg/ml) inhibits proliferation and invasion of MHCC97 cells markedly after cells were treated with aconitine for 4 days.Treatment with aconitine down-regulated the ability of migration and decreased the ratio of p-P38/P38 and protein levels of p-MAPKAPK and p-HSP27.Conclusion:Aconitine inhibits prolif-eration,invasion and migration,and the mechanism may related with P38MAPK signaling pathway.
RESUMO
Objective To observe the clinical effect of benzene sulfonic amlodipine combined with traditional Chinese medicine (TCM) Yangxueqingnao granules for treatment of patients with hypertensive urgencies (HU) with acute headache, and its effect on serum brain derived neurotrophic factor (BDNF) level.Methods A prospective study was conducted, 186 HU patients with acute headache admitted to the Department of Cardiology in the Affiliated Hospital of Southwest University from January 2014 to December 2016 were enrolled, and they were divided into a control group (90 cases) and an observation group (96 cases) by random number table method. The patients in control group received benzene sulfonic amlodipine (10 mg, once a day) and the patients in observation group were additionally given Yangxueqingnao granules (4 g, 3 times a day for consecutive 7 days) on the basis of treatment in control group. The mean arterial pressure (MAP), the nature and location of headache and the levels of serum BNDF were examined before and after treatment and compared between them in the two groups, the degree of headache was evaluated by visual analogue scale (VAS), and the clinical therapeutic effects in the two groups were observed.Results There were no statistical significant differences in MAP (mmHg, 1 mmHg = 0.133 kPa) between the two groups before treatment and at 2 hours, on 1, 3, 7 days after treatment (control group: 99.7±9.5, 94.2±9.1, 88.6±7.6, 81.8±9.3, 75.6±5.3 respectively, the observation group: 95.4±13.5, 91.2±8.1. 88.9±8.7, 83.2±8.6, 77.2±4.8 respectively, allP > 0.05). Compared with the control group, after treatment for 1, 3, 7 days, the nature of acute headache (dull pain, distending pain) was relieved more significantly, the number of patients with whole head headache was decreased more obviously in observation group [dull pain (cases): 16, 8, 3 vs. 28, 24, 18, distending pain (cases): 11, 6, 2 vs. 22, 16, 10, whole head pain (cases): 12, 5, 3 vs. 26, 20, 16, allP < 0.05]. With the prolongation of treatment, the VAS scores in the two groups were gradually decreased, on 7 days after treatment they reached to the lowest levels, and the degree of descent in the observation group was more significant than that in the control group (0.5±0.4 vs. 1.4±0.9,P < 0.05); thelevels of serum BNDF in the two groups were gradually increased after the 1st day of treatment, reached to the highest level on 7 days after treatment,and the degree of increase in observation group was more obvious than that in the control group (ng/L: 24.8±2.3 vs. 17.8±2.2). The therapeutic effective rate of the observation group was significantly higher than that of the control group [70.8% (68/96) vs. 53.3% (48/90),P < 0.05].Conclusion The combination of benzene sulfonic amlodipine and Yangxueqingnao granules can effectively relieve the acute headache in HU patients, and its mechanism is related to the increase in expression of BDNF.
RESUMO
<strong>Objective</strong> To investigate the short- and long-term therapeutic efficacies of intravenous trans- plantation of bone marrow stem cells (MSCs) in rats with experimental myocardial infarction by meta- analysis. <strong>Methods</strong> Randomized controlled trials were systematically searched from PubMed, Science Citation Index (SCI), Chinese journal full-text database (CJFD) up to December 2014. While the experimental groups (MSCs groups) were injected MSCs intravenously, the control groups were injected Delubecco's minimum essential medium (DMEM) or phosphate buffered saline (PBS). Subgroup analysis for each outcome measure was performed for the observing time point after the transplantation of MSCs. Weighted mean differences (WMD) and 95% confidence intervals (CI) were calculated for outcome parameters including ejection fraction (EF) and fractional shortening (FS), which were measured by echocardiogram after intravenous injection and analyzed by RevMan 5.2 and STATA 12.0. <strong>Results</strong> Data from 9 studies (190 rats) were included in the meta-analysis. As compared to the control groups, the cardiac function of the experimental groups were not improved at day 7 (EF: WMD=0.08, 95%CI -1.32 to 1.16, P>0.01; FS: WMD=-0.12, 95%CI -0.90 to 0.65, P>0.01) until at day 14 after MSCs' transplantation (EF: WMD=10.79, 95%CI 9.16 to 12.42, P<0.01; FS: WMD=11.34, 95%CI 10.44 to 12.23, P<0.01), and it lasted 4 weeks or more after transplantation of MSCs (EF: WMD=13.94, 95%CI 12.24 to 15.64, P<0.01; FS: WMD=9.64, 95%CI 7.98 to 11.31, P<0.01). <strong>Conclusion</strong> The therapeutic efficacies of MSCs in rats with myocardid infarction become increasing apparent as time advances since 2 weeks after injection.

RESUMO
BACKGROUND:Autologous bone marrow mesenchymal stem cel transplantation for the treatment of cardiovascular disease has become one of the hotspots, but it is unclear whether the proliferation and directional differentiation of autologous bone marrow mesenchymal stem cels varies changes with age. OBJECTIVE: To explore the proliferation and differentiation changes of rat bone mesenchymal stem cels in different ages. METHODS:The bone marrow mesenchymal stem cels from Sprague-Dawley rats in different age groups were purified and cultured, and then examined by flow cytometry in terms of cel cycle. Meanwhile, neonatal rat cardiomyocytes were co-cultured with bone marrow mesenchymal stem cels. The morphologic changes of bone marrow mesenchymal stem cels and the protein expression of troponin T were detected with immunofluorescence technique. RESULTS AND CONCLUSION: The percentage of bone marrow mesenchymal stem cels in G0/G1 phase was increased with age; while the percentage of expression of troponin T proteins-positive bone marrow mesenchymal stem cels were decreased with age. These findings indicate that the proliferation and differentiation abilities of rat bone marrow mesenchymal stem cels descend with age.
