Abstract:
Objective To explore the correlation between the expression of serum long non-coding RNA bladder cancer associated transcript 1(LncRNA BLACAT1)and long non-coding RNA(LncRNA)-H19 levels and the severity of elderly knee osteoarthritis(KOA).Methods A total of 120 elderly KOA patients who underwent diagnosis and treatment in Jingmen Hospital of Traditional Chinese Medicine from November 2021 to February 2023 were selected as subjects(KOA group).Based on the Kelgren-Lawrence(K-L)classification,these KOA group patients were grouped into mild group(n=41),moderate group(n=45),and severe group(n=34).Meanwhile,those who underwent health examinations at the same time were regarded as control group(n=120).Real-time fluorescence quantitative PCR method was applied to measure the levels of serum LncRNA BLACAT1 and LncRNA-H19.The serum levels of LncRNA BLACAT1 and LncRNA-H19 were compared between KOA group and the control group.The serum levels of LncRNA BLACAT1 and LncRNA-H19 in KOA patients with different degrees of illness were analyzed.Spearman correlation was applied to analyze the relationship between the expression of serum LncRNA BLACAT1,LncRNA-H19 levels and the severity of KOA patients.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum LncRNA BLACAT1 and LncRNA-H19 levels for KOA.Results The serum levels of LncRNA BLACAT1(1.31±0.31)and LncRNA-H19(1.41±0.37)in KOA patients were higher than those in the healthy control group(0.99±0.24,1.03±0.25),and the differences were statistically significant(t=8.941,9.322,all P＜0.05).The serum levels of LncRNA BLACAT1(1.53±0.36)and LncRNA-H19(1.71±0.44)in the severe group were higher than those in the mild(1.13±0.27,1.18±0.29)and moderate groups(1.32±0.31,1.40±0.38)(q=7.806,4.183;8.709,5.200),and the serum levels of the moderate group were higher than that of the mild group(q=3.983,3.884),and the differences were statistically significant,respectively(all P＜0.05).Spearman correlation analysis results showed that the serum levels of LncRNA BLACAT1 and LncRNA-H19 were positively correlated with the severity of the disease(r=0.552,0.414,all P＜0.05).The results of ROC showed that the AUCs of LncRNA BLACAT1 and LncRNA-H19 alone diagnosed KOA were 0.860 and 0.869,with specificity of 74.2％and 80.8％,and sensitivity of 66.7％and 69.1％,respectively.The AUC of the combined diagnosis of KOA was 0.966,with a sensitivity and a specificity of 90.0％,81.7％,respectively.Conclusion The serum levels of LncRNA BLACAT 1 and LncRNA-H19 in KOA patients were elevated and were positively correlated with the severity of KOA patients.Combined detection of the two could effectively predict the occurrence of KOA.
