双相情感障碍患者血清Hepcidin,LncRNA MIAT和CRE的水平表达及与病情程度关系研究OACSTPCD

Objective To explore the expression of serum Hepcidin,long non-coding RNA myocardial infarction-associated transcript(LncRNA MIAT)and creatinine(CRE)in patients with bipolar disorder(BPD)and their relationship with the severity of the disease.Method In this study,150 patients with BPD who were admitted to Baoji Central Hospital from March 2021 to March 2023 were selected as the study subjects and were included in the BPD group.Another 150 healthy subjects were selected as the control group.Hamilton Depression Scale(HAMD)was used to evaluate depression.Young mania ratings scale(YMRS)was used to evaluate the degree of mania.All subjects were tested for serum Hepcidin,LncRNA MIAT and CRE levels.The levels of serum Hepcidin,LncRNA MIAT and CRE were compared between control group and BPD group.The levels of serum Hepcidin,LncRNA MIAT and CRE in BPD groups with different depression/mania degrees were compared.Receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of serum Hepcidin,LncRNA MIAT and CRE in BPD.The relationship between serum Hepcidin,LncRNA MIAT and CRE and the severity of BPD was analyzed.Results The levels of serum Hepcidin(46.17±9.17 ng/L),LncRNA MIAT(11.92±2.65)and CRE(74.02±11.89 μ mol/L)in BPD group were higher than those in control group(22.16±5.23 ng/L,4.11±0.95,57.16±8.61 μ mol/L),with significant differences(t=-27.856,-43.079,-14.066,all P＜0.05).The levels of serum Hepcidin,LncRNA MIAT and CRE increased with the increase of depression/mania in BPD patients(F=22.036,25.463,17.499;19.552,15.791,18.335,all P＜0.05).The combined detection of serum Hepcidin,LncRNA MIAT and CRE(95％CI:0.866～0.949)for BPD diagnosis had an area under the ROC curve of 0.914,with high specificity and sensitivity,which was significantly higher than that of serum Hepcidin alone(95％CI:0.693～0.816),LncRNAMIAT(95％CI:0.696～0.819)alone and CRE(95％CI:0.587～0.701)detection alone(AUC=0.759,0.762,0.614,all P＜0.05).Serum Hepcidin,LncRNA MIAT and CRE were positively correlated with depression severity in BPD patients(r=0.784,0.771,0.826,all P＜0.05).Serum Hepcidin,LncRNA MIAT and CRE were positively correlated with mania severity in BPD patients(r=0.806,0.793,0.831,all P＜0.05).Conclusion The levels of serum Hepcidin,LncRNA MIAT and CRE in BPD patients were higher than those in the normal population,and they were positively correlated with the severity of the disease.Combined detection may have a high diagnostic value.
