Background:Excessive immune cell activation-inflammatory factor theory is one of the most important pathogenic mechanisms of acute pancreatitis(AP). As the release of inflammatory factors is associated with systemic inflammatory response syndrome,seeking of serum cytokine markers for severity assessment of AP is of great clinical importance. Aims:To determine the dynamic changes of interleukin-6(IL-6),hepatocyte growth factor(HGF),and angiopoietin-2(Ang-2) in peripheral blood of AP patients in the first week after admission,and investigate preliminarily the clinical significance of these markers in AP. Methods:Seventy-two AP patients were prospectively recruited from Apr. 2014 to Oct. 2014 at the First Affiliated Hospital of Soochow University and were assigned into three groups:mild AP(MAP,n = 54),moderately severe AP(MSAP,n = 12)and severe AP(SAP,n = 6)according to the Atlanta classification of AP-2012. Thirty healthy subjects were served as controls. Serum levels of IL-6,HGF and Ang-2 were determined by ELISA on the 1st,3rd and 7th day after admission. Results:In the first week after admission,serum levels of IL-6,HGF and Ang-2 were significantly higher in AP patients than in controls(P < 0. 05). In MAP group,all three markers were gradually decreased in the first week;while in MSAP group,IL-6 was gradually increased,Ang-2 was gradually decreased,and HGF decreased after reaching the peak;in SAP group,IL-6 decreased after reaching the peak and HGF and Ang-2 increased again after a decrease. Serum levels of IL-6,HGF and Ang-2 were higher in MSAP group and SAP group than in MAP group at all the time points,but no statistically significant differences were observed between MSAP group and SAP group(P > 0. 05). Conclusions:IL-6,HGF and Ang-2 might play important roles in the pathogenesis of AP,and being the promising serum markers for severity assessment and dynamic monitoring of AP.

Objective To observe the clinical effect of Yi'naokang Capsules combined with Donepezil Hydrochloride Tablets in treating post-stroke cognitive impairment(PSCI).Methods 110 patients who met the diagnostic criteria of PSCI in the outpatient department were included.According to the random number table method,the patients were divided into trial group and control group,with 55 cases in each group.Patients in control group were treated with routine western medicine,including the treatment of Donepezil Hydrochloride Tablets and secondary prevention of stroke such as lowering blood pressure,lowering blood lipid,lowering blood glucose and anti-platelet aggregation.The trial group was treated with Yi'naokang Capsules on the basis of the treatment in control group,and both groups were treated for 6 months.Before and after 6 months of treatment,the cognitive function of patients was evaluated by the Montreal Cognitive Assessment(MoCA)scale.The activity of daily living(ADL)scale was used to evaluate the ability of daily living,and the severity of cerebral white matter lesions was evaluated by Fazekas scale,and the adverse reactions were also observed.Results After 6 months of treatment,the total score of the MoCA,the scores of visual space and executive function,attention,delayed recall and the ADL of the two groups were all improved(P＜0.05),and the improvement degree of the trial group was better than that of the control group(P＜0.05).The Fazekas score of the trial group after treatment was no significant difference when compared with that before treatment(P＞0.05),but it increased in the control group after treatment(P＜0.05),and the effect of delaying white matter lesion in the trial group was better than that in the control group(P＜0.05).Conclusion Yi'naokang Capsules combined with Donepezil Hydrochloride Tablets are superior to Donepezil alone in the treatment of PSCI,which can safely and effectively improve the cognitive function and daily living ability of patients,as well as prolong the progress of white matter lesions.
