Objective To investigate the effect of nicotine on coagulation abnormalities in endotoxemic rats.Methods Ninety-six male SD rats weighing 200-250 g were randomly divided into 4 groups (n=24 each): group normal saline (group NS);group LPS;group nicotine(group NIC)and group α-bungarotoxin (α7 nicotinic acetylcholine receptor antagonist, group α-BGT) . Endotoxemia was induced by LPS 10 mg/kg injected via femoral vein in LPS, NIC and α-BGT groups. In group NIC nicotine 400 μg/kg was injected intraperitoneally at 30 min before LPS injection. In group α-BGT α-BGT 1 μg/kg was injected intraperitoneally at 15 min before intraperitoneal nicotine. Prothrombin time(PT),activated partial thromboplastin time(APTT),fibrinogen(Fib),antithrombin (AT),von Willebrand factor(vWF),plasminogen activator inhibitor-1(PAI-1),D-dimer,platelet count and TNF-α were measured before (baseline) and 2, 4 and 6 h after LPS injection.Results PT and APTT were significantly prolonged and plasma Fib and AT concentrations and platelet count were significantly decreased, while plasma PAI-1, D-dimer, vWF and TNF-α concentrations were significantly increased after LPS administration in group LPS as compared with group NS. Nitotine pretreatment significantly attenuated the LPS-induced changes in group NIC.The effect of nicotine was counteracted by α-BGT. Conclusion Nicotine can attenuate coagulation abnormalities induced by LPS by acting on α7 nicotinic acetylcholine receptor.

Objective Research the correlation between expression of MMP-2 in colorectal cancer and patho- logical factors,or biological behaviors in colorectal cancer.Methods The expression of MMP-2 in 68 cases with col- orectal cancer were detected by immunohistochemical staining.Results The expression of MMP-2 in colorectal can- cer was not correlated with tumor region and histologic type,but related with depth of tumor invasion and metasta- sis.The frequency of positive cases in patients with colorectal cancer with of lymph,node metastasis was significantly higher than that in patients without lymph node metastasis(P

Objective To select valuable biomarkers for diagnosis and predicting outcome of sepsis-related acute respiratory distress syndrome(ARDS) from D-dimmer (DD),yon Willebrand factor (vWF),platelet (PLT),N terminal-pro brain natriuretic peptide (NT-ProBNP),interleukin-6 (IL-6),interleukin-8 (IL-8) and surfactant protein D (SP-D).Methods A total of 48 sepsis accompanied with ARDS patients and 40 sepsis patients were prospectively studied with comparison.The clinical characteristics of all the patients were recorded in detail.The blood samples were obtained within 24 hours of ICU admission.The concentration or activity of the seven biomarkers was quantitatively assayed and the results were recorded.To select the most valuable biomarkers as clinical indices,diagnosis model and death predictive model were constructed by Logistic regression.Results Among the seven candidate biomarkers,SP-D,vWF and IL-8 showed the most value.Their area under the receiver operator characteristic curve (ROC) were 0.758 (P ＜ 0.01),0.783 (P ＜ 0.01) and 0.747 (P ＜ 0.01) respectively,and raised to 0.847 (P ＜ 0.001) when the three biomarkers were combined.IL-8,age greater than or equal to 60 years and APACHE Ⅱ score greater than or equal to 20 were related to ARDS death with 12.138(lnIL-8)(P=0.022),6.157(P=0.040) and7.415(P=0.014) of OR values respectively.Conclusion SP-D,vWF,IL-8 should be valuable for early prediction of sepsis-induced ARDS and the diagnostic accuracy raised through combined utilization.IL-8 may be predictable for prognosis of sepsis related ARDS and the comprehensive evaluation combining clinical indices with IL-8 should be suggested in clinical practice.

Objective To investigate the prevalence of dermatosis affecting pilots in different areas. Methods From Oct. 2007 to Sep. 2008,epidemiological investigation and clinical examination were carried out in 255 pilots stationed at Beijing,Tianjin,Hubei and Shaanxi regions. In order to get the correct diagnosis of dermatosis and the accurate number of infection cases/time,same medication and management were applied for the treatment of those skin disorders. The epideomology of dermatosis in pilots of different troops and age groups were then compared,and the correlation factors affecting the epidemics were analyzed with Chi-square test. Results Among 255 pilots,430 cases (times) were found to suffer from 47 kinds of dermatosis,of whom 72% suffered from two or more kinds of dermatosis. The incidence of superficial mycosis (69.8%) took ranked the highest. The incidence of dermatosis was different among the pilots stationed in different regions. The prevalence of lichen simplex chronicus was higher in the pilots stationed in Beijing,Tianjin and Shaanxi regions than in those in Hubei region,while the prevalence of tinea manuum and tinea pedis showed the opposite status (P 7 year enlistment (P
