Carriage frequencies of alleles and genotypes of 10 functionally important single nucleotide polymorphisms that are located in genes FGA, FGB, APOE, LPL, ACE and CMA1 were analyzed in the ischemic stroke (IS) patients of Russian ethnic descent and in the control group of the same ethnic descent and of similar gender and age. Comparison between patients and control group revealed no significant differences in frequencies of individual alleles and genotypes for all the polymorphic loci studied. However, complex analysis of genetic predisposition using APSampler algorithm revealed carriage of allele (-491A) APOE as a predisposing factor for IS (p = 0.044, OR 3.8, 95% CI 1.0-15.1). Accordingly, carriage of genotype (-491T/T) APOE was associated with resistance to IS (p = 0.044, OR 0.26, 95% CI 0.07-1.0). The allele -249C FGB carriage addition to this genotype enhances its protective properties, p-value of the combination is 2-fold lower than that of the genotype (-491T/T) APOE (OR 0.17, 95% CI 0.04-0.8). Two more protective combinations were identified: biallelic (-427C) APOE + (1595G) LPL and triallelic (-491C) APOE + (1595G) LPL + (-1903G) CMAI (in both cases p = 0.0052, OR 0.18, 95% CI 0.05-0.66). Overall, involvement in formation of the risk of IS development in Russians was evidenced for alleles of four genes: APOE, FGB, LPL and CMA1, where APOE gene involvement was evidenced for alleles of two polymorphic loci, -491T and -427C. Linkage analysis suggested that involvement of these loci in insusceptibility to IS is mutually independent.

Dengzhan Xixin injection (DZXXI), a herbal product prepared from a Chinese herb called Erigeron breviscapus, is a classical and traditional therapeutic for cadiovascular diseases (CVDs), including coronary heart disease (CHD), angina, and stroke, etc. However, its potential pharmacology mechanism against CVDs remains unclear. In this paper, a systems pharmacology-based strategy is presented for predicting drug targets and understanding therapeutic mechanisms of DZXXI against CVDs. The main ingredients were identified by HPLC-diode array detector (DAD). The target fishing was performed on the PharmMapper Server (http://lilab-ecust.cn/pharmmapper/). Potential targets were confirmed by two molecular docking tools, Sybyl-X 1.3 and Ledock to ensure the accuracy. The resulting target proteins were applied as baits to fish their related diseases and pathways from the molecular annotation system (MAS 3.0, http://bioinfo.capitalbio.com/mas3/) and Kyoto Encyclopedia of Genes and Genomes (KEGG) database (http://www.genome.jp/kegg/). Network generation and topological analysis were performed in Cytoscape 3.6.0. 15 main ingredients from DZXXI were identified. Forty five putative drug targets and 50 KEGG pathways, which have highly relevance to the therapeutic effects of DZXXI against CVDs, were then obtained. The systems analysis suggested that DZXXI could attenuate cardiac fibrosis, regulate cardiac contractility, and preserve heart function in adverse cardiac remodeling; meanwhile DZXXI also could have the function of activating blood circulation and dilating blood vessels. DZXXI exerts its therapeutic effects on CVDs possibly through multi-targets including CMA1, epidermal growth factor receptor (EGFR), phenylalanine-4-hydroxylase (PAH), SRC, F7, etc., and multi-pathways including Focal adhesion, mitogen-activated protein kinase (MAPK) signaling pathway, complement and coagulation cascades, Wnt signaling pathway, vascular endothelial growth factor (VEGF) signaling pathway, Renin-angiotensin system, etc.
