RESUMEN
Objective To investigate the relationship between the ratio of soluble hemoglobin scavenger receptor 163 protein(sCD163)/soluble tumor necrosis factor-like weak inducer of apoptosis(sTWEAK)in plasma and prognosis in patients with spontaneous acute cerebral hemorrhage(ACH).Methods From August 2020 to August 2022,90 patients with ACH admitted to the Department of Neurosurgery,Harison International Peace Hospital,Hengshui City were regarded as the research group.According to the Glasgow outcome scale,patients with ACH were separated into the poor prognosis group(n=38)and the good prognosis group(n=52).Another 45 healthy examinee who underwent physical examination were used as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect plasma sCD163 and sTWEAK levels,and the sCD163/sTWEAK ratio was calculated.Pearson method was applied to analyze the correlation between plasma sCD163,sTWEAK levels,sCD163/sTWEAK ratio and clinical data.Logistic regression was applied to analyze influencing factors of poor prognosis in patients with ACH.Receiver operating characteristic(ROC)was applied to analyze the predictive value of sCD163/sTWEAK ratio for poor prognosis of patients with ACH.Results The plasma levels of sCD163,sTWEAK and sCD163/sTWEAK ratio were obviously higher in the research group than those in the control group(P＜0.05).The plasma levels of sCD163,sTWEAK and sCD163/sTWEAK ratio were obviously lower in the good prognosis group than those in the poor prognosis group(P＜0.05).Hematoma volume,National Institutes of Health Stroke Scale(NIHSS)scores,hypertension and subtentorial hemorrhage were lower in the good prognosis group than those in the poor prognosis group,and low density lipoprotein cholesterol(LDL-C)was higher in the good prognosis group than that in the poor prognosis group(P＜0.05).Correlation analysis showed that plasma sCD163,and sTWEAK levels and the sCD163/sTWEAK ratio were positively correlated with bleeding site,hematoma volume,NIHSS score,white blood cell count,platelet count and neutrophil/lymphocyte ratio(NLR)(P＜0.05).Results of Logistic regression analysis showed that sCD163,sTWEAK,sCD163/sTWEAK ratio,hematoma volume,bleeding site and NIHSS score were influencing factors for poor prognosis in patients with ACH(P＜0.05).Results of receiver operating characteristic showed that the AUC of sCD163/sTWEAK ratio in evaluating poor prognosis of patients with ACH was 0.850,and the sensitivity and specificity were 86.84%and 69.23%.Conclusion The sCD163/sTWEAK ratio has a high level in the plasma of patients with ACH,which is associated with poor prognosis and has important value in predicting the prognosis of patients with ACH.
RESUMEN
Objective To investigate the relationship between soluble tumor necrosis factor-like weak inducer of apoptosis levels (sTWEAK) and cardiovascular events in patients with maintenance hemodialysis (MHD).Methods A prospective cohort study was conducted in 64 MHD patients(MHD group).The plasma level of sTWEAK was measured by enzyme-linked immunosorbent assay,N-terminal pro-brain natriuretic peptide (NT-proBNP) and high-sensitive C-reactive protein (hs-CRP) levels were measured by enzyme-linked immunofluorescence method,left ventricular end-diastolic diameter (LVEDd),left ventricular posterior wall thickness (LVPWT),end-diastolic ventricular septal thickness (IVST),left ventricular ejection fraction (LVEF) was determined by echocardiography.The general situation,clinical indicators and occurrence of cardiovascular events of MHD patients were recorded and followed up for 2 years.Fifty healthy people were selected as control group.Results The plasma level of sTWEAK was higher in MHD group than that in control group [(589 ± 122) ng/L vs.(346 ± 127) ng/L],and there was significant difference (P＜ 0.01).During the follow-up period,12 patients underwent cardiovascular events(3 patients died).The plasma level of sTWEAK in cardiovascular event patients was significantly higher than that in non-cardiovascular event patients (695 ng/L vs.458 ng/L),and there was significant difference (P ＜ 0.01).The plasma level of sTWEAK was positively correlated with NT-proBNP in MHD patients(r =0.698,P ＜ 0.05).Logistic repression analysis showed that sTWEAK was the predictor of cardiovascular events of MHD patients.Conclusion The plasma level of sTWEAK probably predicts the ocurrence of cardiovascular event in MHD patients.
