【摘要】 目的 了解北京地区400例新型甲型H1N1流感患者的流行病学和临床特征，总结规律，进一步指导临床诊治。 方法 2009年5-12月期间，收治400例甲型H1N1流感确诊病例，主要采用描述性流行病学方法对患者资料进行回顾性分析，并运用单因素方差分析的方法对结果进行检验。 结果 患者以青年和儿童人群为主，47.0%的患者有明确甲型H1N1流感接触史，主要症状包括发热（98.8%）、咳嗽（85.8%）、咽痛（58.5%）。咽部充血（94.0%）和扁桃体肿大（49.5%）为主要体征。外周血白细胞正常或偏低，349例（82.3%）患者血清铁降低，268例（72.6%）患者C反应蛋白升高。在发病后不同时间内给予奥司他韦治疗的患者发热持续时间和咽拭子的阴转时间有显著差异（Plt;0.001）。 结论 新型甲型H1N1流感发病多以青年和儿童人群为主，以流感样症状为主，多数症状轻微，预后良好，C反应蛋白和血清铁的变化可能对于早期诊断有指导价值，奥司他韦早期抗病毒治疗可以缩短病程。【Abstract】 Objective To investigate the clinical and epidemiologic characteristics of pandemic influenza A (H1N1) virus infection in Beijing. Methods The epidemiological information and clinical characteristics of 400 patients with pandemic influenza A (H1N1) virus infection hospitalized in Beijing 302 Hospital from May to December, 2009 were analyzed retrospectively by descriptive epidemiology. One-way ANOVA was used to assess the results. Results H1N1 virus infection preferentially affected adolescents and young adults. The mean age of the patients was 23 years. A total of 189 (47.0%) of the patients had an identifiable epidemiologic link to another confirmed patient. The most common symptoms were fever (98.8%), cough (85.8%) and sore throat (58.5%). The main physical signs were pharyngeal portion congestion (94.0%) and antiadoncus (49.5%). The number of leukocytes in the peripheral blood was normal or low. The decreased serum iron and elevated C-reaction protein were found in 82.3% and 72.6% of the patients. There was significant difference in the duration of fever and viral shedding from throat swabs among the patients who accept the antiviral medication within the different time. Conclusion H1N1 virus infection preferentially affects adolescents and young adults, and presents with influenza-like illness. The clinical course of H1N1 virus infection is generally mild. The change of C-reaction protein and serum iron may be favorable for the diagnosis of H1N1. Early antiviral treatment may shorten the duration of fever and viral shedding.

Objective To explore the possible anti-inflammatory mechanism of intensive insulin therapy （IIT） by studying the effect of IIT on the levels of TNF-α, IL-6, C-reactive protein （CRP） and APACHE Ⅱ score in biliary pyemia. Methods Twenty eight patients with biliary pyemia who were admitted by our department and given an operation within 24 h form Jan. 2005 to Dec. 2008 were randomly divided into two groups by using random number table numbers: one group treated with IIT （IIT group, n=14） and another group treated with routine insulin therapy （RIT group, n=14）. The inflammatory factors, such as TNF-α, IL-6 and CRP were detected dynamically and the APACHEⅡ score was calculated. ResultsThe level of CRP and APACHEⅡ score on day 5 and 7 and the levels of TNF-α and IL-6 on day 3, 5 and 7 after operation in IIT group were significantly lower than those in RIT group （P＜0.05, P＜0.0１）. Compared with preoperative levels, the IL-6 and APACHEⅡ score in IIT group commenced to decrease on day 3 after operation （P＜0.05）, that was earlier than control group. Conclusion The treatment with IIT can suppress the composition of TNF-α, IL-6 and CRP, protect impaired hepatic cells, and reduce APACHEⅡ score, the degree of systemic inflammation and incidence of MODS.
Objective To explore the clinical significances of serum procalcitonin ( PCT) and Creactive protein( CRP) in diagnosis and severity assessment of sepsis. Methods A total of 72 patients with different severities of sepsis admitted to Wenzhou Second People’s Hospital from June 2005 to September 2007, including 22 cases of sepsis, 26 cases of severe sepsis, and 24 cases of sepsis shock. Meanwhile, twenty non-sepsis patients were enrolled as control group. The differences of serum PCT and CRP levels, acute physiology and chronic health evaluation Ⅱ ( APACHEⅡ) scores and sepsis related organ failure assessment ( SOFA) scores were compared in controls and the septic patients with different severities and different prognosis. Results The PCT levels of patients with sepsis, severe sepsis and sepsis shock were significantly higher than that in the non-sepsis group [ ( 1. 51 ±1. 57) , ( 5. 62 ±3. 78) and ( 13. 56 ±8. 16) vs ( 0. 12 ± 0. 33) μg/L, P lt;0. 05 or P lt; 0. 01, respectively] . The CRP level, APACHEⅡ and SOFA were also increased in septic patients compared to control and progressively elavated by the severities of sepsis patients ( P lt; 0. 05 or P lt; 0. 01) , however, CRP levels were not significant different ( P gt; 0. 05) . The PCT levels, APACHEⅡ and SOFA of the patients with good prognosis were lower than those with poor prognosis( all P lt; 0. 01) , but the CRP levels was not significant different( P gt;0. 05) . Conclusion The serumlevel of PCT is superior to serumlevel of CRP in severity classification and prognosis assessment.
Objective To investigate the expression and clinical significance of soluble triggering receptor expression on myeloid cells-1（sTREM-1） in sepsis patients.Methods Serum concentrations of sTREM-1，procalcitonin（PCT），tumor necrosis factor alpha（TNF-α） and interleukin-10（IL-10） were measured by enzyme-linked immunosorbent assay，while high sensitivity C-reactive protein （hsCRP） level was detected by immunoturbidimetry in 68 patients with sepsis，40 patients with no-infective SIRS，and 20 normal individuals. The diagnostic and prognostic value of sTREM-1 and its comparison with PCT and hsCRP were analyzed. The sequential organ failure assessment （SOFA） score system was used to evaluate the severity of sepsis. The relationship between sTREM-1, PCT , hsCRP , SOFA score，TNF-α ,and IL-10 of the sepsis patients was analyzed，respectively. Results The differences in the serum concentrations of sTREM-1，PCT，hsCRP，IL-10 and IL-10/TNF-α ratio had statistical significance among three groups（Plt;0.05）. The differences in the serum concentration of TNF-α had no statistical significance among three groups （Pgt;0.05）. However，the serum levels of sTREM-1，PCT and hsCRP in the sepsis group were significantly higher than those in the SIRS group （Plt;0.05）. The receiver operating characteristic curve （ROC） analysis showed the area under the curve （AUC） for sTREM-1，PCT and hsCRP were 0.772 （95%CI 0.674-0.871），0.718 （95%CI 0.601-0.835） and 0.664 （95%CI 0.532-0.797），respectively. The serum levels of sTREM-1 and PCT in the non-survivors were significantly higher than the survivors in the sepsis group （Plt;0.01），but the differences in the serum concentration of hsCRP had no statistical significance between the non-survivors and the survivors in the sepsis group （Pgt;0.05）. There were significantly positive correlations between sTREM-1 and SOFA score，IL-10 or IL-10/TNF-α ratio（r value of 0.453，0.301，0.417，Plt;0.05），but no correlation between sTREM-1 and TNF-α（Pgt;0.05）. There was significantly positive correlation between PCT and SOFA score （r=0.436，Plt;0.05），while no relationship between hsCRP and SOFA score（Pgt;0.05）. Conclusions The serum level of sTREM-1 not only be valuable in the diagnosis of sepsis，but also may be used as a prognostic marker in sepsis，as it can reflect the severity of sepsis in certain degree. Furthermore，sTREM-1 or PCT may be superior to hsCRP in diagnosis，prognostic judgment and severity assessment of sepsis.
目的 探讨血清降钙素原（PCT）、C反应蛋白（CRP）与急性生理及慢性健康评分标准Ⅱ（APACHE Ⅱ）评分在转诊肺炎合并脓毒症患者诊断中的相关性，以寻找更为简洁、快速判断其病情严重程度的指标。 方法 2009年1月－2010年12月，选取178例转诊肺炎合并脓毒症患者并进行脓毒症分级，对其进行血清PCT和CRP测定，并与APACHE Ⅱ评分及预后进行相关性分析。 结果 严重脓毒症组及脓毒性休克组患者血清PCT、CRP水平与APACHE Ⅱ评分较全身炎症反应综合征组及脓毒症组高（P＜0.05）；30 d内死亡的患者其血清PCT、CRP水平及APACHEⅡ评分较存活组明显增高（P＜0.05）；转诊肺炎合并脓毒症患者血清PCT与APACHE Ⅱ评分呈正相关（r=0.683，P=0.023），与血清CRP水平呈较弱的正相关（r=0.272，P=0.037）。 结论 对转院肺炎合并脓毒症患者进行血清PCT和CRP测定，对病情评估具有一定临床价值，特别是PCT可作为对转诊肺炎合并脓毒症患者病情程度判断的重要指标，为早期干预及治疗提供依据，值得临床推广应用。
目的 探讨Ｃ反应蛋白(CRP)在慢性阻塞性肺疾病急性加重期(AECOPD)患者治疗前、后的变化和临床意义。方法 纳入2008年1月-9月住院治疗的80例AECOPD患者，分别测定应用抗生素治疗前后CRP、白细胞计数(WBC)、中性粒细胞百分比(N%)、血沉和体温，并比较这些指标的变化情况。结果 AECOPD患者在感染期CRP总阳性率为100.00%，显著高于治疗前WBC、N%、血沉和体温的阳性率(Plt;0.05)；也显著高于感染控制后(Plt;0.05)。 结论 CRP作为细菌性感染的敏感指标之一，也可作为指导临床及时、正确使用或评价抗生素疗效的一个指标。
