Objective To study the changes of coagulation function and platelet-related parameters of patients with acute pancre-atitis(AP) and their clinical significance .Methods 36 patients with AP were served as the AP group ,38 healthy people ,the control group .Healthy people in the control group and patients in the AP group at the time of admission and remission were subjected to detection of serum amylase ,lipase ,leukocytes ,neutrophils ,lymphocytes ,platelets ,mean platelet volume(MPV) ,platelet distribution width(PDW),prothrombin time(PT),thrombin time(TT),activated partial thromboplastin time(APTT),prothrombin activity (PTA) ,international normalized ratio (INR) ,fibrinogen(FIB) and D-dimer(D-D) levels .Results Levels of serum amylase ,lipase , TT ,INR ,FIB ,and D-D of patients in AP group were significantly higher than those in the control group(P<0 .01) ,while their PT , PTA levels were significantly lower than those in the control group (P<0 .01) .Differences of leukocytes ,neutrophils ,lymphocytes and MPV of AP patients between at the time of admission and remission were statistically significant (P<0 .01) .Conclusion De-tections of coagulation function and platelet-related parameters changes of AP patients contribute to evaluation of the patients′con-dition and prognosis .

Objective To explore the feasibility of establishing a swine model of liver cirrhosis with portal hypertension by portal infusion of 80％ alcohol.Methods A total of 13 Guizhou miniature pigs were randomly divided into three groups,experiment group 1 (n=5),experiment group 2 (n=5) and control group (n=3).Experiment groups of pigs received portal infusion of 80％ alcohol in volumes of 5 ml in group 1,and 10 ml in group 2,and the pigs in control group received portal perfusion of saline in volumes of 10 ml.All animals were performed direct portal angiography,the portal vein pressures and diameter were also detected before,immediately and 6 weeks after the infusion.All animals underwent liver biopsies before and 6 hours,1-6 weeks after operation.And contrast-enhanced abdominal CT was performed before and 6 weeks after operation.All animals were dissected 6 weeks after operation,aud each leaf of liver specimens were performed histological examination.Results There was no statistically significant difference of the portal venous pressure and diameter before infusion and 6 weeks after infusion in the experiment group 1 and control group (all P＞0.05).In the experiment group 2,compared with pre infusion,the portal vein pressure and diameter were higher than those of immediately and 6 weeks after infusion (all P＜0.05).In both experiment group 1 and group 2,all pigs had developed into liver fibrosis,the METAVIR score of 2 pigs in group 1 and 5 pigs in group 2 respectively were up to grade 4.Conclusion Portal infusion of 80％ alcohol is more suitable for establishing a swine model of liver cirrhosis with portal hypertension.

Cardiac surgery-associated acute kidney injury(CSA-AKI)is a common and serious complication following cardiac surgical procedures.The conventional diagnostic methods relying on serum creatinine and urine output changes often exhibit delayed responsiveness.Therefore,there is an urgent need for highly sensitive and specific biomarkers to detect and identify high-risk patients with CSA-AKI at an early stage,allowing for timely intervention and improved clinical outcomes.In this paper,the relevant biomarkers of CSA-AKI were reviewed in order to provide valuable informa-tion for the subsequent research on CSA-AKI.
