The relationship between platelet membrane glucoproteins and hs-CRP in elderly patients with chronic cor pulmonary exacerbation / 中国综合临床

ABSTRACT

Objective To investigate the relationshp among Gp Ⅱ b/ⅡⅢ a、CD62p in platelet activation mark-er and high-sensitivity C-reactive protein (hs-CRP) in elderly patients with chronic cor pulmonary exacerbation. Methods The subjects were divided into four groups (42 elderly patients with cor pulmonary exacerbation,42 eld-erly patients with cot pulmonary remission,30 cases of healthy elderly subjects and 30 cases of healthy non-elderly subjects) . The expression of Gp Ⅱ b/Ⅲ a and CD62p were measured with tricolor flow cytometry. Hs-CRP levels were measured by nephelometry and turbidimetry in patients and normal controls. Results Compared with cor pul-monary remission group,healthy elderly group and healthy non-elderly group, the levels of Gp Ⅱ b/Ⅲ a, CD62p and hs-CRP increased significantly in patients with chronic cor pulmonary exacerbation ( all P < 0.001 ). Gp Ⅱ b/Ⅲ a and CD62p results of the elderly patients with cot pulmonary remission were higher than those in healthy elderly subjects (P <0.05) and healthy non-elderly subjects (P < 0. 001 ) . The expressions of both Gp Ⅱ b/Ⅲa and CD62p in healthy elderly subjects were statistically higher than that in healthy non-elderly subjects ( P < 0.05 ). There was a positive con'elation between the Gp Ⅱ b/Ⅲ a、CD62p and hs-CRP in elderly patients with chronic cot pulmonary exac-erbation(r =0.59,P<0.01 ; r=0.54,P<0.01 ). Conclusions The platelet in elderly patients with chronic cot pulmonary exacerbation is overactivated,which is correlated with hs-CRP.
