Objective To investigate the value of hs-CRP in the assessment of risk stratification,coronary artery disease severity and prognosis for patients undergoing PCI with coronary heart disease.Methods A total of 150 coronary heart disease patients were recruited in the study,who had undergone PCI,and before that all the patients had undergone coronary angiography,and the levels of hs-CRP,TG,LDL-C,HDL-C,NT-proBNP and hs-cTnT were measured.Patients were divided into three groups according to the serum concentration of hs-CRP.Gemini score was used to determine the degree of stenosis.After PCI,patients were followed up for 6 months,the major cardiovascular events(MACE)were recorded.The relationships between hs-CRP and other coronary risk factors,Gemini score,vasculopathy count,MACE events were analyzed.Results The serum concentrations of hs-CRP and HDL-C, hs-cTnT were significantly correlated(r=-0.17,0.42,P <0.05).The level of hs-CRP had increasing tendency with the increase of Gensini score,and the serum concentration of hs-CRP in severe vascular lesions group was significantly higher than both mild vascular lesions group and moderate vascular lesions group(P <0.05).The serum concentration of hs-CRP in single-vessel disease patients,double-vessel disease patients and multi-vessel disease patients were (4.64±5.39),(9.86±8.75),(14.93±10.34)mg/L, there was significant difference among them(P <0.05 ).The correlation coefficients of hs-CRP and Gemini score was 0.21 (P <0.05),while hs-CRP and vasculopathy count was 0.18(P <0.05).The incidence of MACE in three groups were 18.52%,43.75%and 58.66%,which were statistically significantly difference(χ2 =13.42,P =0.001).Logistic regression showed that hs-CRP was an independent risk factor for MACE(OR =2.05,95%CI :1.24 -3.39,P =0.005).Conclusion Hs-CRP is an independent risk factor for coronary heart disease in patients with MACE after PCI,and hs-CRP was correlated with PCI patient′s vascular disease. Hs-CRP can be used as an indicator in the assessment of patient′s condition,PCI risk stratification and prognosis.

Feeding adult male rats with gossypol acetic acid at a dose of 15 nig/kg/day for 50 days led to infertility. Spermatogenesis and sperm motility were impaired ( table 1 ) . However, testosterone, K+ and Na+ concentsrations in serum and RTF were found to be unchanged (table 2, 3 ) . It suggests that at low antifertility doses gossypol disrupts spermatogenesis in the seminiferous epithelium without affecting testosterone, K+ and Na+ secretion and translation in testis.
