Three, discuss
The main pathological change of the concurrent lower limb vascular pathological changes of type 2 diabetes mellitus is atherosclerosis (AS), research is thought, AS is a chronic inflammatory disease process from developing into the overall process that lapses to, AS is a kind of chronic inflammation disease, plays key effect on the breaking of inflammation unstable and speckle fibrous cap at speckle.L-6 is the cytokine relevant with inflammatory reaction, phase albumen when it can promote the liver cell synthesized acute, can also cause the generation of AS by other approach, the erosion of CRP, the L-6 of the medium-term and long-term high concentration of blood is to cause one of reason of the generation of diabetic angiopathy, inflammatory reaction can increase the expression of MMP-9, clinical research finds that MMP-9 obviously increases in T2DM macroangiopathy patients serum and the speckle, and MMP-9mRNA expresses and inflammatory factor also obviously increases.Animal Experimental Study also shows in the mass concentration of the AS speckle visible MMP-9 in place and active obviously increase, accumulative MM-29 passes through degraded cells of vascular wall epimatrix (ECM) on the one hand in the part for these, help vascular smooth muscle cell VSMC) the fine and close mesh breaking through the surrounding tissue barrier and constitute by proteoglycan and collagen, therefrom film moves to inner membrance, and breed, secrete a large amount of ECM, form the AS speckle; Secondly MMP-9 can destroy the fibrous cap that is covered in plaque surface, weakens the effect of its opposing stress, makes speckle be easy to break, and secondary thrombus forms and machineization, causes AS damage progress and speckle to enlarge; In addition, MMP-9 also can destroy the interaction between cell and substrate, promotes that VSMC discharges solvable Fas part and film conjunction type tumor necrosis factor 2 α (TNF2 α), induces VSMC that apoptosis takes place, thereby quickens the progress of AS.Therefore, serum MMP-9 level raises can increase the atherosclerotic generation of patient, development, also can cause acute trunk incident by decomposing speckle, and it may be one of circulation mark of diabetic angiopathy that the MMP-9 level increases.If can rationally control the expression of MMP-9 and suppress its activity, then can prevent and alleviate developing of atherosis, vascular conditions, particularly MMP-9 and AS plaques stabilize have substantial connection, therefore, MMP-9 the research aspect the diagnosis of AS plaques stabilize and MMP-9 stablizing in the treatment of AS speckle research can both to future numerous cardiovascular patients beneficial.
Result of study shows that Chinese medicine preparation of the present invention has its intimal hyperplasia of improvement, reduce the effect of plaque thickness and stabilize plaque, its mechanism may be to realize by anti-inflammatory response and the expression that reduces MMP-9, for we in the progress that delays vascular lesion under the diabetes, prophylaxis of acute trunk incident and the early stage LEAD pathological changes of treatment diabetes, improve the diabetictrunk angiopathy prognosis new treatment thinking be provided.
