Abstract:
Objective:To investigate the correlation between the expression of microRNA-16, mircoRNA-124 and mircoRNA-195 in peripheral blood of schizophrenic patients and their cognitive and social functions.Methods:From January 2016 to December 2018, 112 schizophrenic patients admitted to the Second People's Hospital of Taizhou were selected as observation group, and 93 healthy examinees from the Second People's Hospital of Taizhou were selected as control group.The expression of mircoRNA-16, mircoRNA 124 and mircoRNA 195 in peripheral blood was detected by real-time quantitative fluorescent PCR.The cognitive function of patients was evaluated by Chinese version of Montreal Cognitive Assessment Scale (MoCA), and the social function of inpatients with mental illness was evaluated by SSPI.Results:The expression of mircoRNA-16 (0.03±0.01) and mircoRNA 195(0.08±0.03) in peripheral blood of the observation group was lower than that of the control group[(0.12±0.02) and (0.27±0.06)], while the expression of mircoRNA 124 (14.63±3.24) of the observation group was higher than that of the control group (7.45±1.39), the differences were statistically significant( t=41.763, 19.898, 29.389, all P<0.05). The score of MoCA scale in the observation group[(22.17±3.45)points]was lower than that in the control group[(28.39±1.28)points]( t=16.465, P<0.05). The SSPI score of the observation group[(26.58±5.16)points]was lower than that of the control group[(45.37±3.27)points]( t=30.405, P<0.05). MicroRNA-16 and microRNA-195 were positively correlated with MoCA scale score and SSPI scale score ( r=0.641, 0.724, SSPI scale score: r=0.801, 0.657, all P<0.05), while microRNA-124 was negatively correlated with MoCA scale score and SSPI scale score ( r=-0.738, -0.769, all P<0.05). Conclusion:The expression of mircoRNA-16 and mircoRNA-195 in peripheral blood of schizophrenic patients decreased, while the expression of mircoRNA-124 increased.The expressions of mircoRNA-16 and mircoRNA-195 were positively correlated with cognitive and social functions, while mircoRNA-124 was negatively correlated with cognitive and social functions.
