Micro-inflammation state refers to that patient does not have whole body or locally dominant clinical infection sign, but there is low-level, lasting inflammatory conditions, show as inflammatory factor, as tumor necrosis factor (INF-α), interleukin-6 (IL-6), interleukin-1 (IL-1) and inflammation related proteins, as High-sensitivity C reactive protein (hs-CRP), Fibrinogen, serum amyloid protein slightly raise.Stenvinkl etc. propose Chronic Renal Failure Patients and there is malnutrition-inflammation-atherosclerosis (MIA) syndrome, and inflammation is key link wherein, are cause malnutrition and atherosclerotic key factor.CRP level, malnutrition, atherosclerosis are the strong predictor affecting dialysis patient prognosis, there is obvious dependency in CRP level and malnutrition, atherosclerosis, therefore Micro-inflammation state becomes the key that MHD patient prevents cardiovascular complication.CRP is a kind of acute phase protein, and be the most responsive and special index of chronic inflammatory disease, hs-CRP can detect low-level CRP concentration, is the Sensitive mark of low-level inflammation; IL-6 is important inflammatory mediator, stimulates liver to produce CRP.TNF-α produces primarily of the mononuclear phagocyte of activation, is that one has multiple bioactive polypeptide cytokines, closely related with the immunoreation of body, inflammatory reaction, brings out systemic inflammatory response syndrome by active cell cytokine network system.This is studied in 40 routine patients has 31 examples serum CA125 before treatment namely to raise, account for 77.50% of patient's number, consistent with bibliographical information, and normal healthy controls group CRP only has 10% (2 example) to exceed normal value, illustrates that Maintenance Hemodialysis Patients exists Micro-inflammation state really.After this research matched group patients with hemodialysis, CRP, TNF-a, IL-6 raise before all comparatively treating, and illustrate that in hemodialysis, monokaryon one macrophage is activated, a large amount of cytokine activation, IL-6, TNF-a regulate acute-phase response as the proinflammatory factor.
There is the malnutrition of two types in uremic patient, I type malnutrition is reduced by insufficient, the appetite of dialysing and causes albumen and Energy intaking deficiency to cause, and II type malnutrition is relevant to inflammation.Inflammatory factor increases the metabolism of muscle protein, makes body weight loss, occurs becoming thin, and serum albumin synthesis reduces and causes hypoalbuminemia.Uremic patient usually 2 kinds of malnutrition exists simultaneously.Therefore, improve dialysis adequacy in chronic and extra-nutrition material, improve the strategy that Micro-inflammation state is treatment.After treatment group takes pharmaceutical composition of the present invention, average dry weight rises to (57.82 ± 10.25) kg, MAMC meansigma methods by (55.32 ± 12.68) kg before treating and rises to (21.56 ± 4.83) cm by (17.78 ± 6.12) cm before treating.Obviously raise after Alb, PA, Hb treatment in blood biochemistry index, These parameters is improved may improve patient's appetite with pharmaceutical composition of the present invention, and albumen is taken in be increased, and aminoacid reduces relevant with Protein catabolism.After treatment group gives medicine composite for curing of the present invention, CRP, TNF-a, IL-6 reduce before all comparatively treating, showing that nutriture improves can enhancing human body immunity function, developing of defence micro milling, and alleviating of micro milling makes patient's appetite strengthen, the nutrient substance such as protein, carbohydrate is taken in be increased, nutriture is impelled to take a turn for the better, the two is mutually promoted, interacts, the progress of common control MHD patient malnutrition and micro milling, reduce cardiovascular event to occur, improve life in patients, extend life cycle.

Renal tubulointerstitial fibrosis is the progressive common pathological characters proceeding to end-stage renal failure of various chronic renal disease.The mechanism that interstitial fibrosis causes glomerular filtration rate to decline is: between tubule, blood capillary is narrow, and vascular resistance increases, and causes glomerule blood flow and declines; Renal tubules, particularly proximal tubular atrophy consequential damage renal tubular function, affects glomerular filtration rate by bulb feedback mechanism; Interstitial disease of renal tubule also directly can cause glomerular sclerosis or fibrosis crescent pathological changes.Renal interstitial fibrosis shows as the deposition of extracellular matrix (ECM) compositions such as interstitial collagen (I type, II type, type III), fibronectin (FN) and some glycoproteins at kidney, cause normal Reno-colic fistula to change, renal function is faded and is lost.ECM is in continuous metabolic turnover and degrades in the dynamic equilibrium reinvented under normal circumstances, and when this dysequilibrium, ECM will in renal interstitial over-deposit.Type III collagen, Fibronectin are the main components of ECM, the faint expression of the rarely seen renal interstitial of normal rat, during kidney injury, the activation of renal interstitial fibroblast, propagation, type III collagen, Fibronectin are expressed at renal interstitial obviously to be increased, therefore, detect type III collagen, Fibronectin at the expression of renal interstitial, kidney region fibrosis degree can be reflected.TGF-β thinks most important fibrosis somatomedin at present.It stimulates ECM to produce and deposition by following four aspects: (1) induction I, III, IV, collagen type v, FN, LN transcribe, synthesize and secrete.(2) suppress the expression of metalloproteases (MMP), promote PAI and TIMP synthesis, thus reduce ECM degraded.(3) cell surface ECM receptor is promoted---integrin number increases, and makes sticking between cell and substrate strengthen and impel apposition.(4) it or fibroblastic chemotactic factor, and stimulate fibroblast proliferation.TGF-β synthesizes more at the stronger then ECM of the expression of renal interstitial, imply that kidney region fibrosis is more serious.Therefore, block or reduce the expression of TGF-β, contribute to the renal interstitial fibrosis that slows down.This experiment shows that pharmaceutical composition of the present invention can reduce renal interstitial TGF-β 1, ColIII, FN expression, inferring that it can cause the generation of the fine factor by blocking, reducing the synthesis of extracellular matrix, thus reaching the effect of anti-kidney region fibrosis.
