Résumé
Objective To evaluate the plasma levels of D‐dimer in lung cancer and pulmonary tuberculosis (PTB) patients and their clinical significances .Methods The plasma of 130 patients with lung cancer ,126 patients with PTB and 50 healthy controls were collected .All the patients were enrolled in Beijing Affiliated to Chest Hospital Capital Medical University ,from July 2014 to October 2014 .Full‐automatic analyzer was used to examine the level of plasma D‐dimer .Results The levels of plasma D‐dimer in patients with lung cancer were significantly higher than patients with PTB and healthy controls (Z=2 .704 ,P<0 .01);The levels of plasma D‐dimer in patients with PTB were significantly higher than healthy controls (Z=2 .54 ,P<0 .05);The levels of plasma D‐dimer were significantly higher in stages Ⅲ and Ⅳ than stages Ⅰ and Ⅱ(Z=2 .195 ,P<0 .05);The positive rate in patients with lung cancer was significantly higher than patients with PTB (χ2 =10 .525 ,P<0 .01) .Conclusion Activation of coagulation and fi‐brinolysis exist in lung cancer and PTB patients ,the level of plasma D‐dimer is related to the clinical stage of lung cancer .
Résumé
Objective To evaluate the serum levels of cystatin C (CysC)in lung cancer and its clinical significances for kidney assement.Methods The serum of 120 patients with lung cancer and 50 healthy controls were collected.All the patients were en-rolled in Beijing Chest Hospital,Capital Medical University,from June 2012 to October 2013.Full-automatic biochemistry analyzer was used to examine the levels of serum CysC.Results The level of serum CysC in patients with lung cancer was significantly higher than that of healthy controls(t = 4.771,P 0.05).Conclusion Serum CysC was a useful biochemistry marker for kidney assement in lung cancer,and have better clinical significances than BUN and Cr.
