RESUMEN

Objective·To investigate the relationship between serum level of caveolin-1 (Cav-1) and early neurological deterioration (END) in patients with acute cerebral infarction. Methods·A total of 126 consecutive patients with acute cerebral infarction were recruited from July 2016 to January 2017 in Department of Neurology, the First Affiliated Hospital of Chongqing Medical University. The serum Cav-1 levels of all patients were detected by enzyme-linked immunosorbent assay (ELISA) test. The neurological deficits were assessed by the National Institutes of Health Stroke Scale (NIHSS) and the Glasgow Coma Scale (GCS) at the same time. Compared with the admission baseline NIHSS score, if second motor NIHSS score increased ≥ 1 point or the total NIHSS score increased ≥ 2 points within 3 days after hospitalization, they were classified as END group, otherwise they were classified as non-END group. Multivariable Logistic regression analysis was used to examine the independent predictors of END in the patients. Receiver operating characteristic (ROC) curves were obtained to explore Cav-1 levels in predicting END. Results·Serum Cav-1 levels in END group were significantly higher than those in non-END group [(29.88±19.57) ng/mL vs (16.08±13.37) ng/mL, P=0.000]. Based on the ROC curves, the best cut-off point of serum Cav-1 for predicting END was 16.55 ng/mL. The sensitivity and specificity were 73.33% and 74.07%, respectively. Multivariable Logistic regression analysis showed that Cav-1≥16.55 ng/mL remained an independent predictor of END (OR=4.936, 95%CI 1.608-15.155, P=0.005). Conclusion·Serum Cav-1 is an independent predictor of END in patients with acute cerebral infarction.

RESUMEN

<p><b>OBJECTIVE</b>To study the alteration of protein Z (PZ) in patients with cardio-cerebral thrombotic diseases, its clinical significance and relations with FX.</p><p><b>METHODS</b>PZ and FX:Ag were measured by ELISA, and plasma FX:C by first stage method. In 170 patients with acute ischemic stroke (AIS), 40 acute myocardial infarction (AMI) and 60 healthy adults as contrast, PZ, FX:C and FX:Ag were measured and compared between incipience and recurrence, different ages and genders.</p><p><b>RESULTS</b>In AIS and AMI groups, PZ levels decreased significantly to (940.02 +/- 229.82) microg/L and (1071.44 +/- 180.52) microg/L, respectively \[the contrast group was (2257.97 +/- 479.76) microg/L, P < 0.001\]. But FX:C and FX:Ag raised to (136.73 +/- 34.93)% and (135.54 +/- 54.39)% in AIS group; and to (139.53 +/- 29.18)%, (129.75 +/- 21.91)% in AMI group, respectively, while in the contrast group they were (94.33 +/- 22.00)% and (77.22 +/- 13.19)% (P < 0.001). In the comparative research between the AIS group, AMI group and the contrast group, PZ level was clearly found to negatively relate to the level of FX:C and FX:Ag (P < 0.001). Meanwhile, PZ level, FX:C and FX:Ag in recur-AIS group and recur-AMI group exhibited significant differences (P < 0.05) from those in the primary AIS and AMI groups, suggesting that the decrease of PZ levels reflected the pathological process of the disease. In addition, PZ level gradually decreased with the increase of age (P < 0.05), while FX:C and FX:Ag had no relations with age (P > 0.05). No correlation was found in sex with PZ level, FX:C, FX:Ag (P > 0.05).</p><p><b>CONCLUSION</b>PZ level was significantly decreased in AIS and AMI patients and was negatively related to FX:C and FX:Ag. The mechanism leading to FX increase may partially related with the decreased of PZ. PZ level was different in the primary and recurrent disease and was gradually decreased with the increase of age. Lack of PZ might be a etiological factor of cardio-cerebral thrombotic diseases.</p>
