objective to study the regulatory network between specifically expressed LncRNA and mRNA gene function in diabetic anal fistula wounds.Methods Using gene chip technology to detect gene expression profiles of differentially expressed LncRNA and mRNA in diabetic anal fistula wounds and common anal fistula wound tissues, The screening criteria were 2 fold difference and P < 0.05, and then differential expression analysis was performed. Differential expression analysis, Then, KEGG pathway analysis and Pathway Map display were performed on differentially expressed mRNAs. Pick out significant mRNA indicators, These significant mRNA indicators were verified by q-PCR. Get meaningful positive indicators, The positive indicator and the differential LncRNA were then combined to obtain the LncRNA-mRNA co-expression network. Functional verification of different LncRNAs was performed based on the LncRNA-mRNA co-expression network.Results after the chip standardization, 502 up-regulated and 1204 down-regulated long-chain non-coding rnas and mrnas with different expressions were analyzed. MRNA analysis revealed 621 up-regulated pathways and 505 down-regulated pathways, and KEGG pathway analysis revealed 10 up-regulated and down-regulated pathways. Through the Pathway Map display of the most obvious up-regulated and down-regulated pathways, 8 significant mRNA indicators were selected: BMP2, IFNB1, IL6, IL18, PIK3CB, SMAD7, SMAD9, and beta-actin, which were verified by q-pcr, and 5 significant positive indicators were obtained: BMP2, IL6, IL18, PIK3CB and SMAD7 were intersected by the five positive indicators and differentially expressed lncrna-mrna to obtain the lncrna-mrna co-expression network, and different lncrnas were selected based on the lncrna-mrna co-expression network for functional verification.Conclusion the selected 20 lncrna-regulated mrnas are located in the lncrna-mrna co-expression network, and they have reported in various fields to varying degrees, providing direction and focus for the follow-up research on functions and mechanisms, providing new ideas for the research on accelerating the healing of chronic refractory wounds, and providing basic research for the development of healing drugs.
