Objective To study the correlation of Calcitonin,D-dimer and C-reactive protein for evalnating condition and prognosis in patients with severe commnnity acquired pnenmonia,provide the basis for diagnosis,development and adjustment of treatment plan,prognosis assessment.Methods 100 patiens with severe commnnity acquired pnenmonia from January 2012 to September 2013 in our hospital were included as research subjects,50 cases of the severe grou,50 cases of the non-severe group,50 healthy people were included as the control group,then all the patients with severe commnnity acquired pnenmonia were divided into survival group and death group according to hospitalization ending points,the PSI score were judged when entering hospital,Blood samples of all the patient were taken for detecting Cal-citonin,D-dimer and C-reactive protein which were compared between different group,the correlation of PSI and Calci-tonin,D- dimer and C-reactive protein were made.Results ① there were significant differences between the severe group,the non-severe group and the control group,F = 7.003,8.865,10.321,all P <0.01,the Calcitonin,D-dimer and C-reactive protein of the severe group and the non-severe group were significantly higher than the healthy group,t=3. 839、9.745、11.656 和 7.552、13.707、16.721,P <0.05 or P <0.01,the severe group were significantly higher than the non-severe group,t=5.434,7.585,14.725,5.526,all P <0.01.②the Calcitonin,D-dimer and C-reactive protein of the death group were significantly higher than the survival group,t=8.834,9.372,12.011,3.783,P <0.05 or P <0.01.③there were positive correlation between PCT,CRP,D-dimer and PSI score (r=0.645,0.713,0.462,P <0.05 or P <0.01).Conclusion the calcitonin,D-dimer,C-reactive protein detection has important clinical significance for patients with severe commnnity acquired pnenmonia,high level of PCT,D- dimer,CRP may prompt serious illness and poor prognosis,so These indicators should be used in clinical practice.
