C-reactive protein, fibrinogen and white blood cell, as the monitoring index of inflammatory reaction, are very important in the occurrence and development of acute cerebral infarction. OBJECTIVE： To make a comparison between patients with primary hypertension accompanied with acute cerebral infarction and with simple primary hypertension by observing the changes in plasma C-reactive protein and fibrinogen levels as well as white blood cell and differential counts and analyzing their significances. DESIGN ： Controlled observation SETTING ： Ward Building for VIP, Shenzhen Hospital, Peking University. PARTICIPANTS： Totally 133 patients with primary hypertension were selected from Ward Building for VIP, Shenzhen Hospital, Peking University during September 2003 to September 2005, The diagnostic criteria were based on the hypertension diagnosis criteria formulated by the 7^th World Health Organization-International Society of Hypertension Guidelines （WHO-ISH） in 1998. The informed consents were obtained from all the participants. The involved patients were assigned into two groups： primary hypertension group, in which, there were 65 patients with primary hypertension （ degree 2）, including 42 males and 23 females, with mean age of （61 ±14）years and mean blood pressure of （162.7±6.8）/（94.2±8.4） mm Hg （1 mm Hg =0.133 kPa）, and primary hypertension combined with cerebral infarction group, in which, there were 68 patients with primary hypertension combined with cerebral infarction （ meeting the diagnostic criteria formulated in the 4^th National Cerebrovascular Diseases Meeting in 1995 and diagnosed by skull CT or MRI to exclude the patients with lacunar infarction）, including 42 males and 26 females, with mean age of （56±15） years and mean blood pressure of （176.4±9.2）/（96.3±9.7） mm Hg. METHODS： Plasm C-reactive protein and fibrinogen levels, and white blood cell and differential counts of patients in the two groups were examined 24 hours after stroke. The above indexes were re-examined in the primary hypertension combined with cerebral infarction group 72 hours after stroke. White blood cell and differential counts were performed with laser method （East Asia FE-95001 RAM-1, Japan）. The level of C-reactive protein was measured with turbidimetry （BNII Automatic Systems For Analysis, USA）. The level of fibrinogen was measured with algorithm method when prothrombin time was normal and with Clauss method when prothrombin time was abnormal （ACL Automatic Coagulation Analyzer, USA）. MAIN OUTCOME MEASURES： The plasm C-reactive protein and flbrinogen levels, and white blood cell and differential counts 24 hours after stroke in two groups and 72 hours after stroke in primary hypertension combined with cerebral infarction group. RESULTS： All the 133 involved patients participated in the result analysis. The plasm C-reactive protein and fibrinogen levels, and white blood cell and neutrophil counts in patients with primary hypertension were all within the normal range. The plasm C-reactive protein and fibrinogen levels, and white blood cell and neu- trophil counts in patients with primary hypertension combined with cerebral infarction were significantly higher than those in patients with primary hypertension 24 hours after stroke and 72 hours after stroke respectively[24 hours after stroke：（32.12±11.76） mg/L vs. （5.02±3.21 ） mg/L;（4.64±0.75） g/L vs. （3.12±0.49） g/L; （9.32±81）×10^9 L^- 1 vs. （5.78±1.32）×10^9L^- 1 （7.85±2.38）×10^9 L^- 1 vs.（3.49±1.28）×10^9 L^-1,t =7.094, 5.759,4.106,5.491, respectively,all P〈 0.01; 72 hours after stroke： （47.62±18.43） mg/L vs. （32.12±11.76） mg/L; （5.08±0.82） g/L vs. （4.64±0.75） g/L, t =2.864,2.220, respectively, both P 〈 0.05]. CONCLUSION： The increase in fibrinogen level and white blood cell count are the important index in monitoring primary hypertension combined with acute cerebral infarction. The increase in plasm C-reactive protein and fibrinogen levels 72 hours after stroke indicates that plasma C-reactive protein and fibrinogen are very important in the development of disease.展开更多

There is, however, no systemic investigation regarding the role of plasma C-reactive protein （CRP） and white blood cell （WBC） levels in predicting in-hospital clinical events of acute type AAD. Methods The levels of high-sensitivity CRP and WBC counts were systemically determined after admission in 36 patients with acute type A AD. The variations of plasma CRP and WBC levels in different time windows （admission, 1, 2, 3, 4, 6, 8 days） in patients with acute type AAD were analyzed between patients with events and without events. Results During hospitalization, five patients died, and increased levels of CRP and WBC were found in patients died with acute type A AD compared with patients survived （P 〈0.01, respectively）. Medical treatment may significantly decrease inflammatory response in survived patients with acute type A AD. Additionally, patients with complication of pleural effusion showed higher CRP and WBC levers （P=0.046, P=-0.018, respectively）. Lower WBC levels were found in survived patients treated medically （P=-0.001）. Moreover, mean CRP and WBC levels had positive correlations with aortic diameter （r=0.364, P--0.000; r=0.333, P=0.000, respectively） and age （r=0.270, P=0.000, respectively）, while negative correlations with the time from onset of symptoms to hospital admission （r= -0.229, P=0.000, r= -0.200, P=0.002, respectively）. Univariate analysis showed that age 〉65 years, CRP zl 2.05 rag/L, WBC 〉12.16×10^9/L, aortic diameter 〉48 mm, pleural effusion and diastolic blood pressure 〉105 mmHg were associated with hospital mortality. While CRP 〉12.05 mg/L, WBC ≥12.16×10^9/L, aortic diameter 〉48 mm were strongly associated with hospital mortality in multiple Logistic regression analysis. Conclusions The results suggested that CRP and WBC were preferred markers for predicting the clinical events in patients with acute type A AD, especially death during hospitalization. Therefore, further study enrolling larger cohort, prospective study would be warranted.展开更多

文摘目的:评价肝素结合蛋白(HBP)联合脏器功能指标对严重创伤合并脓毒症患者预警诊断和预后预测效能评价研究。方法:回顾性分析2019年1月~2020年9月期间入住浙江大学医学院附属第二医院急诊医学科的多发伤并完成HBP检测患者184例,根据SEPSIS 3.0诊断标准将患者分为脓毒症组(n=89)和非脓毒症组(n=95),追踪患者临床结局分为死亡组(n=43)和非死亡组(n=141)。连续测定患者HBP水平,比较两组HBP峰值差异,评估其诊断脓毒症的效力,以HBP峰值的中位数为界值进一步分析其与临床预后相关性,评估HBP单独及联合总胆红素(TBil)及白细胞(WBC)评估预后的效力。结果:(1)脓毒症组(n=89)与非脓毒症组(n=95)HBP的峰值(71.7±68.6 vs 52.5±56.1)无显著差异(P=0.051)。(2)184例患者中HBP峰值与WBC计数呈正相关(r=0.244,P<0.01),与TBil水平呈正相关(r=0.241,P<0.01)。(3)TBil水平、WBC计数及PCT水平独立诊断脓毒症曲线下面积(AUC)分别是:0.618、0.631和0.718,三者联合AUC为0.684,诊断敏感度为60.7%,特异度为71.6%(P<0.05)。(4)死亡预后相关分析显示:高HBP水平组患者死亡率要显著高于低水平组(30.4%vs 16.3%,P<0.05);WBC计数值也是死亡组显著高于非死亡组(17.5±6.9 vs 12.8±4.7,P<0.01),尤其合并脓毒症者,该值有显著差异(P<0.01)。HBP峰值、TBil水平、WBC计数、SOFA评分及APACHE-II评分对预测脓毒症死亡预后的AUC分别是:0.618、0.603、0.719、0.823及0.811,HBP联合TBil及WBC评估脓毒症预后的AUC为0.750,评估的敏感度为74.4%,特异度为74.5%(P<0.05)。(5)三者联合评估在预测脓毒症预后效力上与人工评分差异无统计学意义(P>0.05)。结论:HBP、TBil及WBC三者联合用于评估多发伤患者发生脓毒症风险的预测效力较高,对于合并脓毒症的外伤患者死亡风险预测具有较高的临床指导价值。
文摘目的探讨血清降钙素原(procalcitonin,PCT)、C反应蛋白(C-reactive protein,CRP)、高迁移率族蛋白B1(recombinant high mobility group protein 1,HMGB1)水平、白细胞计数(white blood cell,WBC)与肺癌合并肺部感染患者的关系,为临床治疗提供参考。方法选取2021年1月—2022年12月广西壮族自治区民族医院收治的159例患者为对象。其中肺癌未合并肺部感染者95例作为对照组,肺癌合并肺部感染者64例作为观察组。根据肺部感染评分(clinical pulmonary infection score,CPIS)将其分为轻度组(n=22)、中度组(n=21)、重度组(n=21)。分析肺癌合并肺部感染者病原菌分布,比较2组炎症因子水平、通气功能,不同程度肺部感染患者炎症因子水平、通气功能,并分析其相关性。结果64例肺癌合并肺部感染者痰液标本共检出69株病原菌,其中有18株革兰阳性菌、42株革兰阴性菌、9株真菌;观察组CRP、PCT、HMGB1、WBC、气道峰压(peak inspiratory pressure,PIP)、呼吸做功(work of breath,WOB)、响应频率(frequency response,Fres)高于对照组,动态顺应性(dynamic pulmonary compliance,Cdyn)低于对照组,差异有统计学意义(P<0.05);轻度组、中度组、重度组血清CRP、PCT、HMGB1、WBC、PIP、WOB、Fres呈依次升高趋势,差异有统计学意义(P<0.05);轻度组、中度组、重度组Cdyn呈依次降低趋势,差异有统计学意义(P<0.05);血清PCT、WBC水平与感染程度呈正相关(r=0.363、0.382,P<0.05)。结论肺癌合并肺部感染患者病原菌主要以革兰阴性菌为主,与肺癌患者相比,其血清炎症因子水平更高,通气功能指标较差,且其水平变化与感染程度存在一定关系,临床上可对相关指标进行监测,为临床诊治肺癌合并肺部感染提供参考依据。
