The AUC, specificity and sensitivity of patients with AMI diagnosed with MCP-1 alone were 0.8084, 81.61 and 69.51%, respectively. Those of patients diagnosed by D-D were 0.7302, 59.77 and 81.71%, those of patients diagnosed by IMA alone were 0.7289, 58.62 and 80.49%, and those of patients detected by the combination of MCP-1, D-D and IMA were 0.9047, 58.62 and 93.90%. In conclusion, the levels of IMA, D-D and MCP-1 in AMI patients are higher than those in the control group. The levels of IMA, D-D and MCP-1 were positively correlated with CTnT and hs-CRP levels in AMI patients. Combined detection of IMA, D-D, and MCP-1 can improve the accuracy.Numerous studies have reported the critical roles of long non-coding RNAs (lncRNAs) in the regulation of osteoarthritis (OA) development. The present study aimed to assess the function and regulatory mechanism of a lncRNA, KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1), in OA in vitro. C28/I2 cells were treated with lipopolysaccharide (LPS) to generate an in vitro OA model. The relative expression levels of KCNQ1OT1, microRNA (miR)-211-5p and transcription factor 4 (TCF4) were determined via reverse transcription-quantitative polymerase chain reaction. The associations between KCNQ1OT1, miR-211-5p and TCF4 were confirmed using a dual-luciferase reporter assay. Furthermore, cell viability was assessed using the MTT assay. Inflammatory cytokine levels were measured using ELISA. The protein expression levels of matrix metalloproteinase-3/13, collagen II/X and TCF4 were detected by western blotting. KCNQ1OT1 and TCF4 were highly expressed in the cartilage tissues of patients with OA and C28/I2 cells treated with LPS (OA cells), whereas miR-211-5p was downregulated concomitantly in OA tissues and cells. Knockdown of KCNQ1OT1 stimulated cel
