ABSTRACT
Objective To understand the correlation and clinical significance between cystatin C and atherogenic index of plasma change in hypertensive patients. Methods At the Quzhou City central hospital between 2014 and 2015, 526 cases of hypertensive patients as hypertensive group and 546 cases of people with normal blood pressure in the healthy check-up as normal blood pressure group were investigated with physical examination, blood biochemical index detection and the serum cystatin C level detection. The analysis of the relationship between the serum cystatin C level and atherogenic index of plasma among two groups was done. Results The evidence that the serum cystatin C level between hypertensive group and normal blood pressure group shows respectively as: 1.12±0.44 (mg/L) and 0.81±0.22 (mg/L), atherogenic index of plasma shows respectively as:0.68±0.03 and -0.22±0.02, both differences were statistically significant (P<0.01) . As the serum cystatin C level increased, the risk of hypertension increased (OR=20.06, 95％CI: 12.67-31.76) . Plasma arteriosclerosis index in hypertensive group was correlated with systolic blood pressure, body mass index, total cholesterol, triglyceride, high-density lipoprotein, LDL cholesterol, and uric acid level respectively, all differences were statistically significant. In addition to the above indicators, the serum cystatin C level in hypertensive group was correlated with serum creatinine level (all P<0.05) . Conclusion The serum cystatin C level and plasma arteriosclerosis index in patients with hypertension both were higher than those with normal blood pressure. These two indicators were correlated with systolic blood pressure and multiple blood lipid indicators. They could be used to monitor arteriosclerosis and target organ damage in patients with hypertension.
ABSTRACT
<p><b>BACKGROUND</b>Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide. Platelet activation may play an important role in pathologic progress in lung cancer. In this study, we aimed to clarify the influence of activated platelets on lung cancer generation and growth, and the relationship among these functional and ultrastructural changes of platelets and the severity of pathogenetic condition in these patients with NSCLC.</p><p><b>METHODS</b>One hundred and thirty-six cases of patients with pathologically confirmed NSCLC were included in this study. Fifty-four healthy people were enrolled as controls. The change of ultra microstructure and activity of blood platelets were observed under the transmission and scanning electron microscope. Simultaneous determination of plasma granule membrane protein 140 (GMP-140) was made.</p><p><b>RESULTS</b>Transmission electron microscopy showed remarkable changes of ultra microstructure of platelets in patients with NSCLC, including swelling, increase of a-granules, vesicles, and glycogenosome. Scanning electron microscopy showed many more surface processes and wrinkles on platelets in patients with NSCLC. The reference plasma levels of GMP-140 of healthy controls were (18.2 +/- 2.7) microg/L. The plasma levels of GMP-140 in patients with NSCLC were (47.8 +/- 12.3) microg/L, which were much higher than those of the controls. There was a medium positive correlation between plasma levels of GMP-140 and amount of a-granules (r = 0.514, P < 0.01) and a high positive correlation between plasma levels of GMP-140 and area of platelet (r = 0.84, P < 0.01) in patients with NSCLC. The Kaplan-Meier survival curve analysis showed significant shift to the left in patients with NSCLC whose a-granules per platelet were 19 or more compared to those 18 or less (Log rank statistic, chi(2) = 17.38, P < 0.01).</p><p><b>CONCLUSIONS</b>There are significant activated changes of ultra microstructure and increased activity of blood platelets in patients with NSCLC. These activated platelets may play an important role in the generation and growth of lung cancer. These changes can be used as a diagnostic index of severity, progression, and prognosis of NSCLC.</p>

Objective To assesse the quality of life of patients after cardiac pacemaker implantation using the Chinese version of SF-36.Methods Ninety-eight patients with permanent cardiac pacemaker implantation were investigated before and after the operation in terms of quality of life by using the Chinese version SF-36.Results Successful surgery was performed on all the 98 patients.The previous symptoms of the patients were improved to vari- ous extend after the operation.The quality of life of the patients was significantly improved after operation as demon- strated by the significant difference of the scores in 9 domains of SF-36 when compared with those before the operation (P
