RESUMEN
Objective To investigate the changes of soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) and omentin-1 in patients with H-type hypertension complicated with acute ischemic stroke, and to analyze the correlation of sLOX-1 and omentin-1 levels with the severity and prognosis of the disease.Methods Totally 136 patients with H-type hypertension complicated with acute ischemic stroke from February2017 to May 2018 were selected as observation group, and 136 non-acute ischemic stroke patients with H-type hypertension in the same period as the control group. The patients of observation group were divided into mild, moderate and severe sub-groups according to NIHSS score, and they were also divided into good prognosis group and poor prognosis group based on modified RANKIN scale (mRS) score. The serum sLOX-1 and omentin-1 levels were detected, and the correlation of sLOX-1 and omentin-1 levels with severity and prognosis of disease was analyzed. Results The serum sLOX-1 level of the observation group was higher, but the serum omentin-1 level lower than that of control group (P < 0.05). With the severity of the disease, the serum sLOX-1 level increased, but the serum omentin-1 level decreased (P < 0.05). The serum sLOX-1 level of good prognosis group was significantly lower, whereas the serum omentin-1 level significantly higher than that of poor prognosis group (P < 0.05). sLOX-1 was positively correlated with NIHSS score and mRS score, while omentin-1 was negatively correlated with NIHSS score and mRS score (P < 0.05). Conclusions The levels of serum sLOX-1 and omentin-1 are closely related to the severity and prognosis of patients with H-type hypertension complicated with acute ischemic stroke, which could be used as markers for evaluating the severity and prognosis of the patients.
RESUMEN
Objective To investigate the correlation between serum lectin like oxidized low density lipoprotein receptor-1 ( sLOX-1 ) and left ventricular diastolic function in patients with essential hypertension. Methods From January 2016 to July 2017, one hundred and forty-six patients with essential hypertension were selected and divided into two groups according to the ratio of E/ A,the left ventricular diastolic function group (76 cases) and the left ventricular diastolic function group (70 cases),the sLOX-1 level of the patients was detected by ELISA method, and the left ventricular diastolic function was evaluated by echocardiography. The correlation between sLOX-1 and left ventricular diastolic function was analyzed. Results The serum sLOX-1 levels in left ventricular diastolic function group (( 208. 12 ± 13. 48 ) μg/ L ) were significantly higher than those inthe left ventricular diastolic function group ((152. 12 ± 12. 96) μg/ L) . The difference between the two groups was statistically significant (t= 6. 586,P= 0. 000). Logistic regression analysis showed that serum sLOX-1 was a influence factor of left ventricular diastolic function (OR= 2. 42,95%CI 1. 42-2. 82,P = 0. 036) . Conclusion The levels of serum sLOX-1 can be used as a indicator of left ventricular diastolic function.
RESUMEN
Objective To investigate the correlation between serum sFas and sLOX-1 with occurrence and development of acute coronary syndrome (ACS).Methods A total of 52 patients definitely diagnosed ACS (ACS group) by coronary artery angiography (CAG) were enrolled,including 23 cases of unstable angina (UA group) and 29 cases of acute myocardial infarction (AMI group),and contemporaneous 58 cases of non-coronary arterial stenosis confirmed by CAG were selected as the control group (NC group).The serum levels of sFas and sLOX-1 were measured by enzyme linked immunosorbent assay.Results Compared with the NC group,the serum levels of sFas and sLOX-1 in the ACS group were increased,the serum levels of sFas and sLOX-1 in the AMI group and UA group were higher than those in the NC group,moreover which in the AMI group were higher than those in the UA group (P＜0.01).The serum sFas level in the ACS group was positively correlated with the sLOX-1 level (r=0.825,P=0.001),but both had no obvious correlation with the serum levels of CK-MB and cTnⅠ (P＞0.05).Conclusion High levels of serum sFas and sLOX-1 may be the risk factors of ACS.
RESUMEN
Objective To investigate whether soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) as the early diagnostic biomarker of acute ST elevation myocardial infarction (STEAMI).Methods Sixty-five patients with STEAMI and 30 patients with stable coranary heart disease or other heart disease(control group) were enrolled as our subjects.Serum sLOX-1 levels were measured.Results The median(P25,P75) of Serum sLOX-1 in the patients with STEMI were 210.0 (130.0,356.0) ng/L,significantly higher than that of control group(65.5 (55.2,85.2) ng/L,Z =6.17,P ＜ 0.001).Logistic regression analysis revealed that sLOX-1 alone was an independent factor associated with STEAMI (B =0.036,P ＜ 0.001).The area under the ROC curve of sLOX-1 for detecting STEMI was 0.895,and 95％ CI was 0.831-0.959 (P＜0.001).Taking sLOX-1 =87.5 ng/L as cut-off value,the sensitivity was 89.6％ and specificity was 82.4％for the diagnosis of STEAMI.Conclusion Serum sLOX-1 was significantly higher in the STEAMI and it might served as the early diagnostic marker for STEAMI.
