Effect of Continuous Blood Purification on Inflammatory State and Immune Response in Patients with Multiple Injury and Sepsis / 现代生物医学进展

ABSTRACT

Objective:To study the effect of continuous blood purification on inflammatory state and immune response in patients with multiple injury and sepsis.Methods:88 patients with multiple injury and sepsis who were treated in our hospital from January 2015 to May 2016 were selected as the research object,they were divided into the control group (n=44) and observation group (n=44) according to random number table method.The control group was given conventional treatment,and the observation group was given continuous blood purification treatment.The acute physiology and chronic health conditions Ⅱ (APACHE Ⅱ)score was observed in two groups Ⅱ at 3 d after treatment.The serum content of Interleukin-2(IL-2),Interleukin-4(IL-4),Interleukin-10(IL-10) and interferon-γ (IFN-γ) were detected by ELISA method.The levels of CD3 +,CD4 +,CD8 + and NK cell were analyzed by flow cytometry.The urea nitrogen (BUN),serum creatinine (Scr),prothrombin time (PT),thrombin time (TT),activated partial blood coagulation time (APTT) were tested by automatic biochemical analyzer.Results:The APACHE Ⅱ score,BUN and Scr levels in observation group were lower than the control group (P＜0.05).The content ofIL-2,IL-4,IL-10 and IFN-γ in observation group were lower than the control group (P＜0.05).The levels of CD3+,CD4+,CD8+ and NK in observation group were higher than the control group (P＜0.05).The levels ofPT,TT and APTT in observation group were lower than the control group (P＜0.05).Conclusion:Continuous blood purification in patients with multiple injury and sepsis had better clinical curative effect,can reduce inflammation,improve immune function and the function of blood coagulation.
