Objective To evaluate the clinical value of serum carcinoembryonic antigen(CEA),neuron specific enolization enzyme(NSE),21-1 non-small cell lung cancer associated antigen(CYFRA21-1),carbohydrate antigen 125(CA125) and ferritin(Fer) in the diagnosis of lung cancer.Methods The levels of CEA,NSE,CYFRA21-1,CA125 and Fer were measured by electrochemlium-inescence in 103 patients with lung cancer,32 patients with benign lung diseases and 40 healthy people.Results The serum levels of CEA,NSE,CYFRA21-1,CA125 and Fer in patients with lung cancer[(110.2±95.5)ng/mL,(50.6±43.4)ng/mL,(32.8±29.5)ng/L,(122.7±110.4)U/L,(854.6±497.2)ng/mL] were significantly higher than those in patients with benign lung diseases and those in healthy people(t=6.21,5.71,6.75,6.62,7.74,P<0.05;t=5.26,4.86,5.81,5.20,6.26,P<0.05).The sensitivity values of CEA,NSE,CYFRA21-1,CA125,Fer and the combined determination containing five tumor markers were 39.81%,24.27%,71.84%,68.93%,77.66% respectively.The sensitivity and specificity of the combined determination containing five tumormarkers were 96.12%,95.00%.Conclusion The joint detection in the diagnosis of lung cancer could improve the sensitivity significantly,to help for early diagnosis of lung cancer,which is value to widely applied in clinic.

Objective:To study the relation between low density lipoprotein and macrophage myeloperoxidase.Methods:Using the reaction that MPO catalyze the oxidation of o dianisidin hydrochloride,MPO activity was determined.Using reverse transcription polymerase chain reaction(RT PCR),MPO gene expression was determined.The two methods were used to observe the relationship between low density lipoprotein and macrophage myeloperoxidase activity.Results:LDL was able to accelerate the hoist of MPO activity, but its effect is less than LPS OX LDL have no this effect When the time of LDL effect was prolonged, MPO activity was enhancing little by little When the concentration of LDL effect was increased, MPO activity was enhancing to max little by little, then it come to plateau Conclusion:LDL non especially induced the hoist of MPO activity and the swelling of MPO secretion The reason of the hoist of MPO activity was likely to make MPO into action and enhance its secretion, but not MPO gene expression

Objective To study the reliability and validity of the clinical neurologic deficit scale in evaluating stroke patients. Methods A total of 222 inpatients with acute stroke onset were included in the study. They were assessed when admitted, at the 14th and 90th day of hospitalization by different physicians using the clinical neurologic deficit scale. Intrarater and interrater reliability were determined using Kappa correlation. The split-half rehability and internal consistency were evaluated using Cranbach's a coefficient. Concurrent validity and the predictive validity were determined by spearman rank correlation coefficients. Construct validity was assessed by the factor analysis and the construct validity of the scale was measured according to the classifications of the Oxfordshire Community Stroke Project ischemic stroke subtypes in the patients with cerebral infarction. Results The scores of intrarater reliability in all items were higher than 0.6, the score of interrater reliability in the item "walking" was 0.542, the split-half reliability and the internal consistency were good as demonstrated by the score of 0.911 and 0.886 respectively, and assessment of reliability of different methods showed that "strength in upper limb" and "strength in hand", were poor as shown by the score of 0.393 and 0.386 respectively. The scale is highly correlated with the NIHSS ( both P=0.000) in both total and subtypes of stroke patients according to the classifications of the Oxfordshire Community Stroke Project by concurrent validity analysis. There was a high correlation between the scores of the scale and Barthel Index and the modified Rankin scales at the 90th day of hospitalization (both P=0.000). Conclusions The clinical neurologic deficit scale has a good internal consistency. There is concurrent validity between the scale and the NIHSS and could predict stroke outcome. Factor analysis of the scale displays the best construct validity in the patients with partial anterior circulation infarction, and could be used to evaluate the focus of vertebrobasilar artery despite its insensitivity.
