Changes of serum high sensitive C-reactive protein in patients with acute cerebral infarction

BACKGROUND： Serum high sensitive C-reactive protein （hs-CRP）, which regards as a high sensitive mark of systemic inflammatory response syndrome, can provide a lot of valuable information for the treatment and prognosis of cerebrovascular disease. OBJECTIVE： To observe the differences of blood glucose, lipid, homocysteine and previous disease history among patients with acute cerebral infarction at various levels of hs-CRP and compare changes of hs-CRP of patients with various degrees of neurologic impairment. DESIGN： Contrast observation. SETTING： Department of Neurology, Shenzhou Hospital, Shenyang Medical College. PARTICIPANTS： A total of 102 patients with acute cerebral infarction were selected from Department of Neurology, Shenzhou Hospital of Shenyang Medical College from February 2005 to September 2006, including 55 males and 47 females aged from 55 to 86 years. All accepted patients met the diagnostic criteria of cerebral infarction established by the Fourth National Cerebrovascular Disease Academic Meeting and were diagnosed with CT or MRI examination. All patients provided the confirmed consent. Based on clinical criteria of neurologic impairment established by the Fourth National Cerebrovascular Disease Academic Meeting, patients were randomly divided into mild group （0 - 15 points, n =46）, moderate group （16 - 30 points, n =38） and severe group （31 - 45 points, n =18）. In addition, based on hs-CRP level within 72 hours, patients were divided into normal group （hs-CRP ≤3 mg/L, n =53） and increasing group （hs-CRP 〉 3 mg/L, n =-49）. METHODS： ① 2 mL venous blood was selected from hospitalized patients in the next morning to separate serum. Quantitative measurement of hs-CRP was dealt with Latex Enhnced Turbidimetric Immunoassay （LETIA）. ②Fasting venous blood was colleted from hospitalized patients in the next morning to measure numeration of white blood cells, fibrinogen, blood glucose, total cholesterol （TC）, triacylglycerol （TG）, high density lipoprotein cholesterol （HDL-C）, low density lipoprotein cholesterol （LDL-C） and homocysteine. ③Measurement data were compared with t test or analysis of variance. MAIN OUTCOME MEASURES： ①Comparisons of serum biochemical indexes among patients with various levels of hs-CRP; ②comparisons of risk factors among patients with various levels of hs-CRP; ③comparisons of levels of hs-CRP among patients with various degrees of clinical neurologic impairment. RESULTS： A total of 102 patients were involved in the final analysis. ①Plasma fibrinogen and numeration of leucocytes were more in the increasing group than those in the normal group （t =4.39, 3.54, P 〈 0.01）; while, there were no significant differences of blood glucose, TC, TG, HDL-C, LDL-C and homocysteine between the two groups （P 〉 0.05）. ② Percentage of patients with hypertension and diabetes mellitus （DM） was higher in the increasing group than the normal group （ Х^2=3.98, 4.23, P 〈 0.05）; while, percentage of patients with smoking in the increasing group was not significantly different from that of patients in the normal group （P 〉 0.05）. ③Level of hs-CRP of patients with severe neurologic impairment was higher than that of patients with moderate neurologic impairment （t =2.273, P 〈 0.05）; that of patients with moderate neurologic impairment was higher than that of patients with mild neurologic impairment （t =2.586, P 〈 0.05）; that of patients with severe neurologic impairment was obviously higher than that of patients with mild neurologic impairment （t = 4.913, P 〈 0.01）. CONCLUSION： ① With the increase of hs-CRP, plasma fibrinogen and numeration of leucocytes of patients with acute cerebral infarction is increased, especially, they are increased remarkably among patients who have history of diabetes mellitus and hypertension. ②Increase of level of hs-CRP can be regarded as one of marks to evaluate severity of acute stroke.

The prognostic value of serum C-reactive protein-bound serum amyloid A in early-stage lung cancer

Background:Elevated levels of serum C-reactive protein(CRP) have been reported to have prognostic significance in lung cancer patients.This study aimed to further identify CRP-bound components as prognostic markers for lung cancer and validate their prognostic value.Methods:CRP-bound components obtained from the serum samples from lung cancer patients or healthy controls were analyzed by differential proteomics analysis.CRP-bound serum amyloid A(CRP-SAA) was evaluated by coimmunoprecipitation(IP).Serum samples from two independent cohorts with lung cancer(retrospective cohort,242patients;prospective cohort,222 patients) and healthy controls(159 subjects) were used to evaluate the prognostic value of CRP-SAA by enzyme-linked immunosorbent assay.Results:CRP-SAA was identified specifically in serum samples from lung cancer patients by proteomic analysis.CRP binding to SAA was confirmed by co-IP in serum samples from lung cancer patients and cell culture media.The level of CRP-SAA was significantly higher in patients than in healthy controls(0.37 ± 0.58 vs.0.03 ± 0.04,P < 0.001).Elevated CRP-SAA levels were significantly associated with severe clinical features of lung cancer.The elevation of CRPSAA was associated with lower survival rates for both the retrospective(hazard ration[HR]= 2.181,95%confidence interval[CI]= 1.641-2.897,P < 0.001) and the prospective cohorts(HR = 2.744,95%CI = 1.810-4.161,P < 0.001).Multivariate Cox analysis showed that CRP-SAA was an independent prognostic marker for lung cancer.Remarkably,in stages l-ll patients,only CRP-SAA,not total SAA or CRP,showed significant association with overall survival in two cohorts.Moreover,univariate and multivariate Cox analyses also showed that only CRP-SAA could be used as an independent prognostic marker for early-stage lung cancer patients.Conclusion:CRP-SAA could be a better prognostic marker for lung cancer than total SAA or CRP,especially in earlystage patients.

Downstream signaling of reactive oxygen species,protein kinase C epsilon translocation and delayed neuroprotection in sevoflurane preconditioned rats following cerebral ischemia/reperfusion

BACKGROUND： Brief exposure to the anesthetic sevoflurane results in delayed neuroprotection, However, few studies have addressed delayed neuroprotection after preconditioning with a single administration of sevoflurane. OBJECTIVE： To explore the relationship between a single preconditioning administration of sevoflurane and reactive oxygen species production and protein kinase C-epsilon （PKC-ε ） translocation. DESIGN, TIME, AND SETTING： The randomized, controlled, animal experiment was conducted at the Central Laboratory, Xiangya Hospital, Central South University, China from November 2007 to April 2008. MATERIALS： A total of 120 healthy, male, Sprague Dawley rats were equally and randomly assigned into five groups： sham operation, ischemia/reperfusion, sevoflurane, 2-mercaptopropionylglycine （2-MPG, a selective reactive oxygen species scavenger） ＋ sevoflurane （MPG ＋ sevoflurane）, and MPG. Sevoflurane （Baxter, USA） and MPG （Sigma, USA） were used in this study. METHODS： Intervention consisted of three procedures. （1） MPG injection： a selective reactive oxygen species scavenger, MPG （20 mg/kg）, was infused into the rat caudal vein in the MPG and MPG ＋ sevoflurane groups. （2） Sevoflurane preconditioning： 30 minutes following MPG injection, rats in the sevoflurane and MPG ＋ sevoflurane groups breathed a mixed gas of 2.4% sevoflurane and 97.6% oxygen for 60 minutes. Rats in the sham operation, ischemia/reperfusion, and MPG groups breathed 100% pure oxygen for 60 minutes. （3） IschemiaJreperfusion： 24 hours after sevoflurane or pure oxygen preconditioning, middle cerebral artery occlusion models were established in the ischemia/reperfusion, sevoflurane, MPG ＋ sevoflurane, and MPG groups. Following 2 hours ischemia/6 hours and 24 hours reperfusion, the carotid artery was separated, but the middle cerebral artery was not occluded, in the sham operation group. MAIN OUTCOME MEASURES： In the ischemic hemisphere, PKC-ε translocation in the rat parietal cortex was measured by Western blot analysis. Infarct volume was calculated using the TTC assay. Neurological deficits were evaluated in rats using a scoring system of 8 points. RESULTS： After 6 hours reperfusion, the ratio of PKC-ε in membrane/（cytosol ＋ membrane） was significantly less in the sham operation group than in the ischemia/reperfusion, sevoflurane, MPG ＋ sevoflurane）, and MPG groups （P 〈 0.05）. The ratio of PKC-ε in membrane/（cytosol ＋ membrane） was significantly greater in the sevoflurane group than in the sham operation, ischemia/reperfusion, MPG ＋ sevoflurane, and MPG groups （P 〈 0.05）. No significant differences were observed in the ischemiaJreperfusJon, M PG ＋ sevoflurane, and MPG groups （P 〉 0.05）. Following 24 hours reperfusion, the ratio of PKC-ε in membrane/（cytosol ＋ membrane） was significantly less in the sham operation group than in the ischemia/reperfusion, sevoflurane, MPG ＋ sevoflurane, and MPG groups （P 〈 0.05）. No significant differences were detected in the ischemia/reperfusion, sevoflurane, MPG ＋ sevoflurane, and MPG groups （P 〉 0.05）. Compared with the ischemia/reperfusion, MPG ＋ sevoflurane, and MPG groups, infarct volume was significantly smaller, and neurological deficits were significantly improved, in the sevoflurane group （P 〈 0.05）. No significant differences in infarct volume and neurological deficits were observed among the ischemia/reperfusion, MPG ＋ sevoflurane, and MPG groups （P 〉 0.05）. Infarcts or neurological deficits were not detected in the sham operation group. CONCLUSION： A single preconditioning administration of sevoflurane reduced infarct volumes and improved neurological deficits in ischemic rats. Delayed neuroprotection may be mediated by reactive oxygen species and correlated to PKC- ε activation.

降钙素原与C-反应蛋白/血清白蛋白比值对结直肠癌术后患者吻合口漏的预测

结直肠癌是消化道中较为常见的恶性肿瘤,其目前多采用手术切除的方式进行治疗,术后吻合口漏(anastomotic leakage,AL)是外科手术常见感染性并发症。术后发生AL会影响患者预期化学治疗时间,增加患者经济负担及二次手术可能,延长住院时长,加剧医患矛盾等。炎症指标可用于AL的早期预测,便于临床科室给予治疗方案。降钙素原(procalcitonin,PCT)是具有广泛生物学活性的多效性蛋白质,在结直肠癌术后AL的预测或排除中有重要作用,C-反应蛋白/血清白蛋白比值(C-reactive protein/serum albumin ratio,CAR)是反映全身炎症、免疫水平和营养状态的重要指标。二者均在早期对AL的预测有效,二者的联合应用可能存在更大的预测价值。

目的 探讨C反应蛋白与白蛋白比值(CAR)联合握力和血清前白蛋白对食管癌患者生存期及营养不良的预测价值。方法 回顾性选取212例食管癌患者作为研究对象,收集患者的基本资料和治疗前CAR、握力、血清前白蛋白检测结果,评估患者营养不良情况并随访总生存期。采用受试者工作特征(ROC)曲线评估治疗前CAR、握力和血清前白蛋白水平对患者营养不良的预测价值,采用Kaplan-Meier生存曲线及Cox回归模型分析治疗前CAR、握力和血清前白蛋白水平对患者生存预后的预测价值。结果 ROC曲线分析结果显示,握力预测食管癌患者营养不良的曲线下面积(0.625)最大,其后依次为血清前白蛋白、CAR(分别为0.604、0.594);根据约登指数确定CAR、握力、血清前白蛋白的最佳截断值分别为0.732、23.1 kg、0.190 g/L,三者联合预测营养不良的灵敏度高达80.7%。Kaplan-Meier生存曲线分析结果显示,CAR增高(≥0.732)、握力降低(<23.1 kg)、血清前白蛋白水平降低(<0.190 g/L)患者的总生存期分别短于CAR<0.732、握力≥23.1 kg、血清前白蛋白水平≥0.190 g/L的患者,差异有统计学意义(P<0.01);多因素Cox回归分析结果显示,治疗前CAR增高(≥0.732)、握力降低(<23.1 kg)、血清前白蛋白水平降低(<0.190 g/L)是食管癌患者生存预后不良的独立危险因素(P<0.05)。结论 治疗前CAR、握力和血清前白蛋白是评估食管癌患者营养状态和生存预后的重要指标,三者联合检测有助于营养不良的早期诊断与及时干预,或可改善食管癌患者的生存预后。

血清铁蛋白作为急性时相反应蛋白在布鲁菌病中的应用

目的:比较急、慢性布鲁菌病(简称布病)患者治疗前和治疗中外周血铁蛋白水平,评估血清铁蛋白与急、慢性布病炎性反应和布病治疗转归的关系。方法:选取急、慢性期且未接受抗生素治疗的布病患者各36例作为治疗前组;抗生素治疗10 d左右的急、慢性期布病患者各36例作为治疗中组;选取健康体检者25例作为对照组。采用酶联免疫吸附试验测定各组样本的血清铁蛋白水平,统计分析血清铁蛋白水平在各组间的差异。结果:治疗前急、慢性期和对照组血清铁蛋白水平具有明显差异(P<0.01);急、慢性组铁蛋白水平均比对照组明显增高(P<0.01);急性铁蛋白水平比慢性组明显升高(P<0.01)。治疗中急、慢性期和对照组血清铁蛋白水平具有明显差异(P<0.01);急、慢性布病组铁蛋白水平均比对照组明显增高(P<0.01);急性布病铁蛋白水平比慢性布病明显降低(P<0.01)。治疗中急性期、慢性期布病铁蛋白水平均比治疗前明显降低(P<0.001)。结论:血清铁蛋白与布鲁菌病的炎症反应程度有关,可用于监测布鲁氏菌病的炎症反应程度和评估治疗效果。
