RESUMEN
Objective To investigate the levels of serum CXC-chemokine ligand 16(CXCL16)and anti-neu-trophil cytoplasmic antibody(ANCA)in patients with allergic rhinitis and their clinical diagnostic value.Meth-ods A total of 84 patients with allergic rhinitis(allergic rhinitis group)treated in the hospital from January to December 2022 were selected as the study objects,and were divided into mild group(44 cases)and moderate and severe group(40 cases)according to the severity of their disease.Another 80 healthy subjects who had physical examination in the same period were selected as the control group.The levels of CXCL16 and ANCA in serum were determined by enzyme-linked immunosorbent assay.The correlation between serum CXCL16 and ANCA levels and inflammatory factors[interleukin(IL)-4,IL-9,IL-13]and immunoglobulin E(IgE)was analyzed by Pearson.The value of serum CXCL16 and ANCA levels in the diagnosis of moderate and severe allergic rhinitis was evaluated by receiver operating characteristic(ROC)curve.Results Compared with con-trol group,the levels of IL-4,IL-9,IL-13 and IgE in allergic rhinitis group were significantly increased,and the difference was statistically significant(P＜0.05).Compared with control group,serum CXCL16 and ANCA levels in allergic rhinitis group were significantly increased,and the differences were statistically significant(P＜0.05).The area under the curve(AUC)of serum CXCL16 and ANCA in patients with allergic rhinitis was 0.897 and 0.844,respectively.The AUC of combined diagnosis was 0.959,both of which were better than that of individual diagnosis(Z=2.164,3.474,P＜0.05),and the specificity was 93.75％.The sensitivity was 89.29％.The levels of serum CXCL16 and ANCA in patients with allergic rhinitis increased with the se-verity of the disease(P＜0.05).Pearson correlation analysis showed that serum CXCL16 and ANCA levels were positively correlated with IL-4,IL-9,IL-13 and IgE in patients with allergic rhinitis(P＜0.05).ROC curve analysis results showed that the AUC of the patients diagnosed with moderate and severe allergic rhini-tis by serum CXCL16 and ANCA was 0.862 and 0.832,respectively,and the AUC of the combined diagnosis of CXCL16 and ANCA was 0.949,both of which were better than those diagnosed separately(Z=1.981,2.378,P＜0.05),and the specificity was 90.91％.The sensitivity was 90.00％.Conclusion The levels of se-rum CXCL16 and ANCA in patients with allergic rhinitis increased significantly,and increased with the severi-ty of the patients'disease,both of which have certain value in the clinical diagnosis of allergic rhinitis.
RESUMEN
Objective To investigate the expression and prognostic value of serum receptor for advanced glycation end products(RAGE)and CXC-chemokine ligand 16(CXCL16)in patients with sepsis complicated with acute respiratory distress syndrome(ARDS).Methods A total of 234 patients with sepsis diagnosed and treated in a hospital from January 2019 to January 2022 were selected as the study subjects,and were divided into 82 patients with sepsis complicated with ARDS(ARDS group)and 152 patients with sepsis without ARDS(non-ARDS group)according to whether the subjects were complicated with ARDS.ARDS group was divided into survival group(n=50)and death group(n=32)according to the survival status within 28 days of admission.Another 60 healthy subjects who underwent physical examination in the same period were se-lected as the control group.Serum RAGE and CXCL16 levels were detected by enzyme-linked immunosorbent assay.Pearson correlation analysis of serum RAGE and CXCL16 levels with sequential organ failure assess-ment(SOFA)score,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and oxygenation index in patients with sepsis and ARDS.Multivariate Logistic regression analysis of prognostic factors of sep-sis complicated with ARDS.The predictive value of serum RAGE and CXCL16 on the prognosis of sepsis complicated with ARDS patients was analyzed by receiver operating characteristic curve.Results The serum RAGE and CXCL16 levels in ARDS group were higher than those in non-ARDS group and control group,and the serum RAGE and CXCL16 levels in non-ARDS group were higher than those in control group,the differ-ence was statistically significant(P＜0.05).Compared with the survival group,the mechanical ventilation time,intensive care unit stay time,procalcitonin,SOFA score,APACHE Ⅱ score,serum RAGE,CXCL16 lev-els were higher in the death group,and the oxygenation index was lower,with statistical significance(all P＜0.05).The serum RAGE level in patients with sepsis complicated with ARDS was positively correlated with SOFA score and APACHE Ⅱ score(r=0.603,0.671,P＜0.05).Serum CXCL16 levels were positively corre-lated with SOFA score and APACHE Ⅱ score(r=0.655,0.707,P＜0.05).Serum RAGE and CXCL16 were negatively correlated with oxygenation index(r=-0.712,-0.683,P＜0.05).Multi-factor Logistics regres-sion analysis showed that serum RAGE and CXCL16 were independent risk factors for death within 28 days of admission in patients with sepsis complicated with ARDS.The area under the curve(AUC)of combined de-tection of serum RAGE and CXCL16 for predicting death within 28 days of admission in patients with sepsis complicated with ARDS was 0.882,which was higher than that of single index detection of serum RAGE and CXCL16,and the difference was statistically significant(Z=4.450,4.906,P＜0.05).Conclusion The com-bined detection of serum RAGE and CXCL16 is helpful to evaluate the clinical prognosis of sepsis complicated with ARDS patients.
RESUMEN
Objective To explore the correlation between serum levels of CXC chemokine ligand 16(CXCL16) and carotid artery atherosclerosis in patients with acute cerebral infarction(ACI) .Methods A total of 36 cases of patients with ACI were enrolled in ACI group ,and 30 individuals received physical examination were enrolled into control group .Levels of blood lipid ,high‐sensitive C‐reactive protein(hs‐CRP) and serum CXCL16 were detected ,and the carotid atherosclerotic plaques and changes of carotid intimal‐medial thickness(IMT) were examined by using the Color Doppler ultrasonography .Results The serum levels of CXCL16 in ACI group[3 .58(1 .06 -12 .83)ng/L] was higher than that in control group[1 .57(0 .61 -3 .34)ng/L] ,had statistically significant difference(P<0 .05) .The carotid IMT were higher in ACI group[(1 .19 ± 0 .36)mm] than that in control group[(1 .01 ± 0 .18) mm] ,had statistically significant difference(P<0 .05) .In ACI group ,the serum level of CXCL16 was higher in patients with vul‐nerable plaques than that in patients with stable plaques ,had statistically significant difference(P<0 .05) ,Serum levels of CXCL16 were correlated with carotid IMT and levels of hs‐CRP(r=0 .497 ,P<0 .05 ;r=0 .442 ,P<0 .05) .Multiple linear stepwise regres‐sion analysis showed that CXCLl6 was one of the independent risk factors for the development of carotid atherosclerotic plaques . Conclusion High serum levels of CXCLl6 and hs‐CRP might be independent risk factors for the development of carotid atheroscle‐rotic plaques ,and CXCLl6 might be closely correlated to the vulnerability of carotid atherosclerosis plaques .
RESUMEN
Serum levels of human CXC-chemokine ligand 16,basic fibroblast growth factor,plateletderived endothelial cell growth factor,and number of endothelial progenitor cells were determined in 80 patients with type 2 diabetes mellitus and 40 normal control subjects.It was found that there were some disturbances of angiogenesis in diabetic patients.These abnormalities were more pronounced in these patients with old age,hyperglycemia,raised HbA1c,and presence of vascular diseases.
