OBJECTIVE:To observe clinical efficacy and safety of Shuxuetong injection combined with alprostadil in the treat-ment of acute cerebral infraction(ACI). METHODS:A total of 123 ACI patients selected from our hospital during Mar. 2014-Sept. 2016 selected as research subjects were divided into observation group (62 cases) and control group (61 cases) according to ran-dom number table. Control group was additionally given Alprostadil injection 2 mL+0.9% Sodium chloride injection 100 mL, ivgtt,qd,on the basis of routine treatment. Observation group was additionally given Shuxuetong injection 6 mL+0.9% Sodium chloride injection 250 mL,ivgtt,qd,on the basis of control group. Both groups were treated for 2 weeks. MPV,FIB content, hemorheology indexes,neurologic impairment degree score before and after treatment as well as clinical efficacy,the occurrence of ADR were compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in MPV,FIB content, hemorheology indexes or neurologic impairment score between 2 groups (P>0.05). Compared with before treatment,MPV,FIB content,hemorheology indexes and modified Rankin scale of 2 groups were all decreased significantly;Barthel index and NIHSS scores were increased significantly,and each aspect of observation group was better than that of control group,with statistical sig-nificance(P<0.05). Total response rate of observation group was 95.16%,which was significantly higher than 85.25% of control group,with statistical significance(P<0.05). No severe ADR was found in 2 groups. CONCLUSIONS:Shuxuetong injection com-bined with alprostadil can significantly improve the neurological function of ACI patients,improve hypercoagulable state by reduc-ing MPV and FIB content,and have good therapeutic efficacy and safety.

Objective To explore the impacts of astragalosideⅣ( AST-Ⅳ) on the experimentally atherosclerotic formation in ApoE-deficient mice. Methods ApoE-deficient mice were randomly divided into AST-Ⅳ and control groups, both groups were fed with high-fat diet, and were killed after 12 weeks of treatment. The plaque areas were measured; the percentage of CD4 +CD25 + T cells were determined by flow cytometry;the levels of supernatant cytokine such as interferon ( IFN )-γ, interleukin ( IL )-10 and transforming growth factor-β (TGF-β) were measured by enzyme-linked immunosorbent assay (ELISA). Results The plaque area of AST-Ⅳ group was ( 815. 78 ± 165. 43 )μm2 , which was smaller than that in control group of (2152. 13 ± 525. 47)μm2. The percentage of CD4 +CD25 +Treg accounted for (9. 86 ± 1. 78)％ of CD4 + cells, which was higher than that in control group (2. 52 ± 1. 43) ％. Compared to con-trol group, the supernatant levels of IL-10 and TGF-βwere significantly higher, and IFN-γwas significantly lower in AST-Ⅳ group (P<0. 05). Conclusions By influencing the regulatory T cell-mediated immune tolerance, AST-Ⅳ might inhibit atherosclerosis in mice.
