  [Abstract] Objective To investigate the effects of lipoxin and ulinastatin on Ang expression in endothelial cells of sepsis and its mechanism. Methods 60 patients with sepsis treated in our hospital from January to December 2016 were randomly divided into two groups. The control group was treated with ulinastatin. The study group was treated with lipoxin and ulinastatin. The Ang expression in endothelial cell between the two groups of patients was compared. Results There was no significant difference in Ang expression between the two groups before treatment(P>0.05). The expression of Ang-1 in the study group was significantly higher than that in the control group after treatment. And the expression of Ang-2 in the study group was significantly lower than that in the control group after treatment(P>0.05). There was no significant difference in renal function between the two groups before treatment(P>0.05). After treatment, the renal function of the study group was significantly better than that in the control group(P0.05). After treatment, the coagulation function of the study group was significantly better than that in the control group(P    1资料与方法
  1.1一般资料
  选取2016年1~12月我院收治的脓毒症患者60例,纳入标准:患者的体温超过38℃或者低于36℃;患者额度心率超过 90 次/min;患者PaCO2(二氧化碳分压)低于4.0 kPa;患者的白细胞数超过11.0×109/L或低于3.0×109/L[2]。排除标准:合并HIV患者;长期应用强的松患者;妊娠哺乳期女性[3]。将患者随机分为两组,对照组30例,男18例,女12例,年龄19~76岁,平均(41.2±2.6)岁;研究组30例,男20例,女10例,年龄18~75岁,平均(40.3±1.9)岁。两组患者的一般资料比较,差异无统计学意义(P>0.05)。具有可比性。受试者均知情同意,且本研究经过医院伦理委员会批准。
  1.2方法
  对照组应用乌司他丁(国药准字H19990134,广东天普生化公司生产,药品规格:10万U)治疗,20万U乌司他丁+30 mL生理盐水,静脉注射给药,1次/d,持续治疗7 d[4]。研究组在对照组患者基础上联合应用脂氧素(国药准H20040505,南京金益柏生物科技有限公司,药品规格:48T/96T)治疗,1 μg/kg的脂氧素+3 mL生理盐水,静脉注射给药,1次/d,持续治疗7 d[5]。
  1.3观察指标
  治疗前后应用酶联免疫法(ELISA)检测Ang-1及Ang-2表达,同时检测患者的肾功能指标[6]。采集空腹静脉血5 mL,分别检测血肌酐(BUN)、尿素氮(SCr)以及胱抑素C(Cystatin C)[7]。治疗前后检测两组患者的凝血功能,采集空腹静脉血5 mL,应用自动生化仪检测凝血酶原时间(PT)、血小板计数(PLT)、D-二聚体(D-D)以及活化部分凝血活酶时间(APTT)[8]。
  1.4 统计学方法
  数据统计应用SPSS18.0软件,计数资料采用χ2检验,计量资料采用t检验,P0.05),治疗后研究组Ang-1表达显著高于对照组,Ang-2表达显著低于对照组(P0.05),治疗后研究组患者肾功能显著优于对照组(P0.05),治疗后研究组患者凝血功能指标显著优于对照组(P0.05),治疗后研究组Ang-1表达显著高于对照组,Ang-2表达显著低于对照组(P    综上所述,脓毒症患者应用脂氧素和乌司他丁治疗,能够降低内皮细胞Ang表达水平,改善患者的肾功能以及凝血功能相关指标,有利于改善患者预后以及生活质量,临床上值得推广应用。
