Changes in expression of serum chemokine CXCL13 and IL-6 after hip replacement, and the relationship with lower limb vein thrombus

摘要

Changes in the expression of serum chemokine CXC ligand 13 (CXCL13) and interleukin-6 (IL-6), and the relationship with lower limb vein thrombus were explored. A total of 128 patients undergoing hip replacement in The First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine from May 2017 to June 2019 were selected, and the patients suffering from lower limb vein thrombus were enrolled as group A and other patients not suffering from it were enrolled as group B. Enzyme-linked immuno-sorbent assay was employed to determine the levels of serum chemokine CXCL13 and IL-6, and receiver operating characteristic curves of serum chemokine CXCL13 and IL-6 levels in diagnosing restenosis after surgery were drawn. Pearson's correlation coefficient was adopted to analyze the correlation between serum chemokine CXCL13 and IL-6, and the logistic regression analysis to analyze the risk factors affecting hip replacement in patients. The levels of serum CXCL13 and IL-6 in group A were significantly higher than those in group B (both P<0.001). The specificity and sensitivity of serum CXCL13 level in diagnosis of lower limb vein thrombus after hip replacement were 61.76 and 80.00%, respectively, and those of serum IL-6 level in diagnosis were 70.59 and 66.67%, respectively. Serum CXCL13 level was positively correlated with serum IL-6 level (P<0.001), and age, body mass index (BMI), CXCL13 level and IL-6 level of the patients were independent risk factors affecting the efficacy of hip replacement. Serum CXCL13 level and serum IL-6 level can be used as biological indexes for prediction of early lower limb vein thrombus after hip replacement, and logistic regression analysis revealed that the age of the patients, BMI, diabetes history, hyperlipidemia history, hypertension history, CXCL13 level and IL-6 level are independent risk factors affecting the efficacy of hip replacement.
