Carry out as mentioned above CLP.Behind CLP 1,5,10 or 10 and 20 hour the time, intravenous is inculcated people I α Ip concentrate (30mg/kg BW) or carrier (normal saline, the 1.5ml/ rat is behind the CLP 1 hour the time or behind the CLP 10 and 20 hours the time).20 hours the time, the downright bad caecum of excision also uses the warm physiological saline solution solution of 40ml with the abdominal cavity washed twice behind the CLP.Then abdominal incision is sewed up layer by layer.Simulation is excised program with regard to the caecum that the clinical setting of removing the septicopyemia focus carries out in the CLP animal whenever possible.Then allow animal arbitrarily feed and drinking-water and monitor over 10 days and record survival.
Statistical analysis
The result is expressed as on average ± SE.Use variance one tail analysis (ANOVA) and Tukey to test more on the same group laboratory animal.Calculate survival rate and relatively next by the test of logarithm level by the Kaplan-Meier method.If the difference of P<0.05 value of thinking is significant.The change of bikunin mrna expression behind the CLP
Bikunin is the active part of I α Ip.Liver is the main source of bikunin.Therefore, we select bikunin mrna expression in the liver to react the generation of I α Ip.As shown in Figure 3, during 5h, the mrna expression of bikunin does not change in the liver behind CLP, yet, behind CLP, compare in the animal of the water of doing evil through another person during 20h, find to reduce by 32% (P<0.05).
Behind the CLP 125The t of I-I α Ip 1/2Change
The half-life that the blood content of the radioactive label I α Ip that injects during by the rear 12h of measurement sepsis outbreak changes to calculate I α Ip.As shown in Figure 4, behind the CLP 125The t of I-I α Ip 1/2Significantly improve to 11.8 ± 2.7h (P<0.05) from 5.6 ± 0.3h
I α Ip is to the effect of survival rate
The survival rate of single carrier administration after the excision of CLP and caecum when 1h (behind the CLP) was 75% at the 2nd day and was reduced to 50% (Fig. 5) at 5-10 days.Yet, behind the CPL during 1h administration people I α Ip in the whole 10 days observation stage, survival rate is increased to 92% (P<0.05; Fig. 5).Although behind CLP 5 or during 10h administration people I α Ip survival rate is increased to 64% and 73% separately, these raisings do not have significance,statistical (Fig. 6).The survival rate of twice carrier administration after the excision of CLP and caecum when 20h (behind the CLP 10 and) was 56% at the 2nd day and was reduced to 44% (Fig. 7) at 5-10 days, and comparing with a carrier administration (Fig. 5) does not have significant difference.Yet, behind the CLP 10 and during 20h administration people I α Ip in the whole 10 days observation stage, survival rate is increased to 81%, comparing with vehicle group is (P<0.05 of significant difference; Fig. 7).
Sepsis is the clinical symptoms that is characterised in that systemic inflammatorome, coagulopathy, respiratory failure, myocardial dysfunction, renal insufficiency and neuro-cognitive defective.It has been generally acknowledged that this symptom is that endogenous inflammatory mediator by the excessive initiation of invading micro-organism causes.These media comprise material such as cytokine, reactive oxygen species and the protease that mononuclear cell, macrophage, endotheliocyte and the neutrophil of activation discharge.In the serious inflammatory reaction, various blood and histiocyte comprise multinuclear type granulocyte, and born of the same parents discharge bacteriolyze protease outward and enter in the circulation.The normal born of the same parents' inner oxide matter that produces can cause tissue and organ injury and improve the clotting of plasma and the non-specific hydrolysis of complement factor in such protease and the phagocytosis.The release of neutrophil cell protease, especially human leukocyte elastase have related to the progress of the individual complication of sepsis.The order of severity of their blood plasma level and infection induced inflammation is closely related with the organ failure's who is about to occur high predicted.
In the process of people's septic shock, except the proteinase activity that improves, also reported the I α Ip level that reduces.The serious individuality that reduces of I α Ip concentration has higher mortality rate.Our result shows that the gene expression of bikunin in the CLP animal livers significantly is lower than in the sham-operation animal.In primates, pig and rodentine various tissues, detected and interior-mrna expression that the alpha inhibitor family protein is relevant.These genes that studies show that all member sources of I α Ip family are mainly at the liver transcription.Our result also shown with sham-operation and compared, and 5 or 20 hours the time, the bikunin gene expression in other organs (that is, intestinal and kidney) does not significantly change (data do not show) behind CLP.
Only observing remarkable downward modulation in liver shows that this organ is the important sources of I α Ip 20 hours the time behind the CLP, and in addition, in pyemic late period, the bikunin gene expression in the liver significantly reduces.In treatment, reported that bikunin has beneficial effect to the people as the prophylactic treatment of the organ injury after preventing the pancreatitis behind the gastrectomy or alleviating operation on heart.Measure bikunin in the bacteremic acute canine model of pathogenic escherichia coli effect studies show that similar result, have the improvement of hematodinamics variable and kinemic standardization and mean arterial pressure.Because the plasma half-life of bikunin very short (approximately 10 minutes), the half-life that therefore prolongs bikumin keeps the beneficial effect that this medicament continues and shows importance.Our result shows that the I α Ip half-life in the sham-operation animal is 5.6h.When we injected radiolabeled I α Ip when sepsis shows effect rear 12h, we found that the Increased Plasma Half-life of I α Ip is to 11.8h.These results show that I α Ip clearance rate significantly reduces in the sepsis process.Yet even have the clearance rate of reduction, the blood plasma level of I α Ip is still significantly lower in the sepsis individuality.That research before us has shown is early stage after the sepsis outbreak (that is, behind the CLP 1 hour), and administration low-purity I α Ip keeps whole body oxygen consumption and the whole body oxygen extraction ratio of cardiac output and whole body oxygen transmission and raising.In addition, the generation of I α Ip downward modulation TNF-α and reduce hepatocyte injury and lactic acidosis during 20h behind the CLP.Administration I α Ip had improved the survival of sepsis animal when in addition, sepsis showed effect rear 1h.
By-product as the classification of commercial scale blood plasma separates I α Ip albumen.Separation method height, Sync enrichment contain the main blood plasma form of bikunin albumen (I α I and P α I).Therefore, in this preparation, obtained the physiology compositions of blood plasma I α Ip.Survival rate when administration I α Ip excised rear 10 days with CLP and caecum when the mortality rate result of study of carrying out showed behind CLP 1 hour is increased to 92% from 50%.Although administration people I α Ip is increased to survival rate 64% and 73% separately 5 or 10 hours the time behind CLP, these raisings do not have significance,statistical.
Yet, behind CLP 10 and during 20h administration people I α Ip significantly survival rate is increased to 81% from 44%.Therefore, to appear be that useful additive comes for the survival rate that improves many microorganisms sepsis progression to I α Ip.In a word, in pyemic process, the bikunin gene expression in the liver reduces and the half-life of I α Ip was increased to 11.8 ± 2.7 hours from 5.6 ± 0.3 hours, has reduced the bikunin in the sepsis although show the clearance rate reduction.Behind the CLP 1 hour the time administration I α Ip survival rate is increased to 92% from 50%, and when behind the CLP 5 or during 10h administration I α Ip do not significantly improve.Yet 10 and 20 hours double injection I α Ip are increased to 81% with survival rate from 44% behind the CLP.The administration people I α Ip that postpones but repeat has improved the survival rate behind the CLP.
