RESUMO

Objective To investigate the clinical significance of platelet activation markers CD62p and PAC-1 in patients with hypertension and coronary heart diease.Methods To select patients who were in the Second Affiliated Hospital of Dalian Medical University between January 2012 and September 2012,42 patients with hypertension,46 patients with coronary heart disease.Flow cytometry was used to test the positive percentage of the platelet surface activation markers CD62p and PAC-1 .To observe the difference among hypertension group,coronary heart disease group and health control group;hyper-tension and coronary heart disease group.Results The positive percentage of platelet activation markers CD62p and PAC-1 in hypertension (36.36±9.62,7.18±8.20)%,coronary heart disease group (42.74±14.60,8.81±12.53)% showed sta-tistically significant differences (t=4.150~5.853,P<0.01)compared with healthy control group (26.82±9.13 ,1.09± 1.05)%.The positive percentage of CD62p in coronary heart disease group (42.74±14.60)% was also higher than that of hypertension (36.36±9.62)%,and the difference between them was of statistical significance (t=2.444,P<0.05).Con-clusion The hypertensive patients and coronary heart disease were in pre-thrombotic state,the activation of platelet increase significantly.Molecular markers should be measured in hypertensive patients and coronary heart disease for prevention and treatment of thrombotic disease complication.

RESUMO

Objective To study the correlation between the level of serum high sensitivity C-reactive protein (hs-CRP) and induced sputum cell counts,pulmonary function and asthma control test (ACT) in order to investigate the clinical application value of serum hs-CRP for the acute exacerbation bronchial asthma patients.Methods Thirty acute exacerbation bronchial asthma patients were collected as asthma group,14 healthy people during the same period were collected as control group.The fasting serum hs-CRP was examined in control group and before and after treatment of 5-7 d in asthma group.The induced sputum was obtained by ultrasonic atomizer 4.5% sodium chloride,and the percentage of eosinophils (EOS%),neutrophil,macrophages,lymphocytes was calculated.The pulmonary function index was determined in control group and before and after treatment in asthma group.ACT score was performed in asthma group.The correlation between the serum hs-CRP and induced sputum differential leukocyte count,the pulmonary function index and ACT score was analyzed by Spearman correlation analysis.The effect of the serum hs-CRP and induced sputum EOS% on inflammatory response of acute exacerbation bronchial asthma was evaluated by receiver operating characteristic (ROC) curve analysis.Results Two cases were excluded in asthma group.The serum hs-CRP before and after treatment in asthma group was higher than that in control group[4.18(2.12-11.12) and 3.40(2.02-8.91) mg/L vs.1.48(1.03-4.81) mg/L,H =18.939,P< 0.01].The serum hs-CRP before treatment was higher than that after treatment in asthma group (P < 0.01).In asthma group,the serum hs-CRP had positive relationship with induced sputum EOS% (r =0.849,P =0.000).There were negative correlations between the serum hs-CRP and the pulmonary function index such as one second forced expiratory volume percent predicted,one second forced expiratory volume occupied vital capacity ratio,maximum mid-expiratory flow percentage of predicted (r =-0.617,-0.559,-0.398,respectively,P =0.000,0.002,0.036,respectively).It was also found that the serum hs-CRP and ACT score had the remarkable Spearman linear correlation (r =-0.511,P =0.005).The area under the ROC curve of the serum hs-CRP was 0.713 (P =0.003).Conclusions There are significant correlations between the serum hs-CRP and induced sputum EOS%,pulmonary function,ACT score in the acute exacerbation bronchial asthma patients.It is found that hs-CRP could be considered as one of the potential marker to evaluate the systemic inflammation level of bronchial asthma.

RESUMO

Objective:To investigate the relationship of the changes of peripheral bloos T cell subsets and NK cell with non-Hodgkin's lymphoma(NHL).And to investigate the change of the cell immune function of NHL and chronic lymphadenitis.Methods:Peripheral blood T cell subsets,NK cell with NHL,chronic lymphadenitis patients and 50 normal controls were detected quantitatively with FCM.Results:Compared with the normal controls,the number of CD3~+,CD4~+T cell,CD4~+/CD8~+ ratio markedly reduced,while those of CD8~+T cells increased.These were no significant changes in NK cell.Compared with the group of chrnic lymphadenitis,the number of CD8~+T cell,NK cell markedly increased,while these were no significant changes in CD3~+,CD4~+T cell and reduction of CD4~+/CD8~+ ratio.Conclusion:NHL patients cell function was suppressed.The detection of T cell subsets and NK cells are clinically valuble on the diagnosis,treatment and prognosis of NHL.
