抵抗素和Hs-CRP在全身炎症反应综合征患者中的预警作用

目的探讨抵抗素与高敏-C反应蛋白(hs-CRP)对全身炎症反应综合征患者病情和预后的判断作用。方法将100例入住急诊ICU的SIRS患者分为多器官功能障碍综合征组(MODS组)和非MODS组,存活组和死亡组;选择健康体检者40例作为对照组。采用酶联免疫(ELISA)法检测血清抵抗素含量,采用免疫比浊法对血清Hs-CRP进行测定;分别检测血清抵抗素和Hs-CRP浓度,并进行APACHEⅡ评分。结果SIRS患者抵抗素和Hs-CRP浓度明显高于对照组(P<0.01);MODS组和死亡组抵抗素和Hs-CRP浓度和APACHEⅡ评分分别明显高于非MODS组和存活组(P<0.01)。SIRS患者抵抗素和Hs-CRP浓度与APACHEⅡ评分呈正相关(r=0.81,0.79,P值均<0.01),SIRS患者抵抗素浓度与Hs-CRP浓度呈正相关(r=0.77,P<0.01)。结论在SIRS患者中早期检测血清抵抗素和Hs-CRP浓度对患者病情和预后有判断作用。     

免疫调理治疗对脓毒症患者血CD4+CD25+T细胞的影响

目的 了解脓毒症患者外周血调节性T细胞(CD4+CD25+Tregs)比例水平及其与机体细胞免疫之间的关系,并探讨免疫调理治疗对其水平的影响.方法 选择滕州市中心人民医院住院治疗的脓毒症患者40例,随机分成治疗组和对照组,治疗组加用乌司他丁和胸腺肽α1作抗炎和免疫调节治疗,分别于治疗前和治疗后第3,第8天抽外周静脉血,检测T淋巴细胞亚群、CD4+CD25+Tregs,TNF-α,IL-6,IL-10水平,同时APACHEⅡ评分.结果 治疗前两组患者CD4+CD25+Tregs细胞水平明显升高,总淋巴细胞数、T细胞比例下降,其中以CD4+T细胞下降更明显,CD4+/CD8+明显下降,IL-6,TNF-αt水平升高;治疗后,两组患者CD4+C125+Tregs降低,总淋巴细胞数、CD4+/CD8+比值升高,APACHEⅡ评分和IL-6,TNF-αt水平均下降,治疗组改善更明显.结论 外周血CD4+CD25+Tregs细胞比例水平,可以作为评价机体免疫能力及预后新指标;联合应用胸腺肽α1和乌司他丁治疗脓毒症,可提高患者免疫力,显著降低APACHEⅡ评分、IL-6,TNF-α水平,改善患者病情.

Abstract：

Objective To investigate the percentage of CD4 + C125 +Tregs in peripheral blood of patients with sepsis and its effect on cell immunity so as to unravel the effect of immunomodulatory therapy on it. Method Fourty patients with sepsis in ICU were randomly (random number) divided into experimental group and control group . The patients of experimental group were treated with Ulinastatin and immunoregulation agent (Thymosin αl) as well. The blood specimens were collected just before treatment, 3 days and 8 days after treatment. The percentages of CD4 + CD25 + Tregs and lymphocyte subsets were detected by using FCM (flow cytometry), and TNF-α, IL-6 and IL-10 assayed by using ELISA, and APACHE Ⅱ scores were calculated. Results Before treatment, the percentage of CD4 + CD25 + Tregs increased, and the number of lymphocytes and the percentage of T lymphocytes decreased, especially the CD4 + T lymphocytes and CD4+/CD8+ decreased more markedly, and the levels of IL-6 and TNF-α increased. After treatment,the percentage of CD4+ CD25 + Tregs was decreased, the number of lymphocytes and CD4 +/CD8 + increased, and the levels of APACHE Ⅱ score, IL-6 and TNF-α decreased especially in the experimental group decreased more significantly (P ＜ 0. 05). Conclusions The percentage of CD4 + CD25+ Tregs in peripheral blood can reflect the immune status of patients with sepsis and become a novel indicator to estimate the progress of sepsis, and the immunity and prognosis of patients. Treating the patients with Thymosin αl and Ulinastatin can raise their immunity, decrease the levels of IL-6, TNF-α and APACHE Ⅱ score and improve their prognosis.     

加强治疗病房人工气道病人痰培养细菌耐药性监测

目的了解加强治疗病房（ICU）人工气道病人呼吸道感染的病原菌分布特征与细菌耐药情况。方法对我院2007年1月至12月ICU人工气道病人痰标本所有细菌分离株及其耐药进行回顾性分析。结果细菌总数507株,革兰阴性杆菌81．5％,革兰阳性球菌13％,真菌5．5％;革兰阳性菌中,耐甲氧西林金黄色葡萄球菌（MRsA）占金黄色葡萄球菌的89．7％,耐甲氧西林凝固酶阴性葡萄球菌（MRCN）占凝固酶阴性葡萄球菌100％;革兰阴性菌分离株仍占多数,对第三代头孢菌素耐药率较高,其中鲍曼不动杆菌所占比例明显增加,达到38．9％。万古霉素对MRSA、MRCN及肠球菌属的敏感率均为100％。结论ICU人工气道病人下呼吸道感染以革兰阴性菌感染为主,且鲍曼不动杆菌所占比例明显增加;细菌耐药率较前明显升高。应加强ICU细菌耐药监测,了解细菌分布及耐药变化,指导临床合理用药,防止耐药菌株的传播。
