Complex 1 is of monoclinic system, space group P21 with a = 5.136（4）, b = 25.577（19）, c = 8.174（6） A, V = 1078.6（14） A3, Mr = 513.41, Z = 2, Dc = 1.581 g/cm3, F（000） = 686, μ = 0.840 mm-1, S = 1.119, Rint = 0.0637 and w R = 0.1456. In complex 1, four IMPAA- and four Co（II） ions form a S-shaped 52-membered macrocycle [Co4（IMPAA）4]4＋. Two carboxlate oxygen atoms link the macrocycles to form a one-dimensional chain. IMPAA- ligands bridge one-dimensional chains to yield a novel three-dimensional metal-organic framework（MOFs）. The complex is stable up to 350 ℃.展开更多

The subjects were divided into the control group (n=50) and the treatment group (n=50) randomly. The control group was treated with sodium ozagrel, the treatment group was treated with danhong injection combined with sodium ozagrel, and both the two groups were treated for 14 days. The serum IL-8, TNF-α, VEGF, TBIL and NSE of the two groups before and after treatment were compared.Results:There were no significantly differences of the serum IL-8, TNF-α, VEGF, TBIL and NSE of the two groups before treatment. The serum IL-8, TNF-α, NSE levels of the two groups after treatment were significantly lower than before treatment, the serum VEGF, TBIL levels of the two groups after treatment were significantly higher than before treatment, and that of the treatment group after treatment were significantly better than the control group.Conclusion:Danhong injection combined with sodium ozagrel can significantly reduce the serum IL-8, TNF-α, NSE levels, improve the serum VEGF, TBIL levels, and reduce inflammation, promote the nerve functional recovery of the old patients with acute cerebral infarction, and it was worthy clinical application.展开更多
