Methods: Sixty patients with POAG and forty five patients with senile cataract (control group) were enrolled in the study prospectively. Aqueous humor samples were obtained by paracentesis from glaucoma and cataract patients who were undergoing elective surgery. Aqueous humor and?corresponding plasma samples were analyzed for Hep concentrations by enzyme-linked immunosorbent assay. Results: Hep levels were significantly lower in aqueous humor of POAG patients with respect to the comparative group of cataract patients (P < 0.001). No significant difference in the levels of Hep in plasma of POAG and cataract patients. A positive correlation was found between plasma/aqueous humor Hep concentration in POAG versus the control group (P < 0.001). No significant correlation was found between Hep levels and the severity of visual field loss. Conclusion: Lower levels of aqueous humor Hep may be associated with POAG. In addition, Hep may be useful protein derivatives levels in aqueous humor of POAG patients as a consequence of glaucomatous damage.展开更多

Methods Eighty patients with STEMI diagnosed by electrocardiogram （ECG） were selected. The concentration of plasma NT-proBNP was measured by electrochemiluminescence immunoassay, and the value of NT-proBNP concentration to evaluate the degree of severity and complexity in coronary artery lesion by coronary angiography （CAG） was analyzed. Results The more serious and more complex of coronary artery lesion in patients with ST-segment elevation myocardial infarction, the higher the concentration of plasma NT-proBNP was （ P 〈 0. 05 ）. Conclusion The concentration of plasma NT-proBNP may be a useful marker to evaluate the degree of severity and complexity of coronary artery lesion in patients with ST-segment elevation myocardial infarction. （ S Chin J Cardiol 2009 ; 10 （ 1 ） ： 15-18）展开更多
