Abstract:
Objective To explore the correlation between the serum levels expression of microRNA(miR)-133a-3p,protein tyrosine phosphatase nonreceptor type 22(PTPN22)and the severity of psoriasis vulgaris.Methods A total of 86 patients with psoriasis vulgaris who were admitted to Cangzhou People's Hospital from January 2022 to June 2022 were collected as the observation group.They were separated into a progressive group(n=41)and a quiescent group(n=45)based on the area and severity of the skin lesions.Meantime,86 healthy individuals undergoing plastic surgery examinations were regarded as the control group.Real time fluorescent quantitative PCR(qRT-PCR)method was applied to detect the relative expression levels of miR-133a-3p and PTPN22 in serum.Target Scan Human website was applied to predict the targeting relationship between PTPN22 and miR-133a-3p.Spearman method was applied to analyze the correlation between the expression levels of miR-133a-3p and PTPN22 in serum of patients with psoriasis vulgaris,the psoriasis area and the psoriasis area and severity index score(PASI).Logistic regression was applied to analyze the influencing factors of severity in patients with psoriasis vulgaris.Results Compared with the control group,the serum miR-133a-3p(1.85±0.46 vs 1.05±0.21)expression level in the observation group was increased,while the PTPN22 mRNA(0.76±0.13 vs 1.02±0.18)expression level was reduced,and the difference were statistically significant(t=14.671,10.859,all P<0.05).Compared with the quiescent group,the serum miR-133a-3p(2.05±0.52 vs 1.67±0.41)expression level in the progressive group was increased,while the PTPN22 mRNA(0.66±0.11 vs 0.85±0.15)expression level was reduced and the differences were statistically significant(t=3.780,6.643,all P<0.05).Target Scan Human website predicted that there may be a targeting relationship between miR-133a-3p and PTPN22.Spearman analysis showed that there was a positive correlation between serum miR-133a-3p and PASI score in patients with psoriasis vulgaris(r=0.469,P<0.05),while serum TPN22 mRNA level was negatively correlated with PASI score(r=0.469,P<0.05).Serum miR-133a-3p[OR(95%CI)=2.884(1.261～6.595)]was an independent risk factor for the severity of psoriasis vulgaris,while PTPN22[OR(95%CI)=0.562(0.367～0.860)]was an independent protective factor(all P<0.05).Conclusion The expression level of miR-133a-3p in serum of patients with psoriasis vulgaris was increased,while the expression level of PTPN22 was reduced.The two were closely related to the PASI score and may to some extent reflect the severity of psoriasis patients.
