Non-surgical treatment of lumbar intervertebral disc protrusion without blood stasis:a serum proteomic analysis / 中国组织工程研究

ABSTRACT

BACKGROUND: Proteomics is a well studied research method, but its application in the non-surgical treatment of lumbar intervertebral disc protrusion (LIDP) is little reported. OBJECTIVE: To screen the differentially expressed proteins in patients with LIDP but without blood stasis before and after non-surgical treatment by proteomics. METHODS: Sixty patients with LIDP but without blood stasis were selected, and treated with non-surgical treatment for 4 weeks. The differentially expressed proteins were screened and identified by iTRAQ combined with LC-MS/MS. The bioinformatics analysis of the identified proteins was carried out, and the curative effectiveness was investigated. RESULTS AND CONCLUSION: Compared with those before treatment, the Visual Analogue Scale scores were significantly (P ＜ 0.05), the Japanese Orthopedic Association scores were significantly increased decreased (P ＜ 0.05), and the excellent and good rate reached 95.0% post-treatment. A total of 300 differentially expressed proteins were screened and 25 significantly expressed proteins were identified (P ＜0.05). Bioinformatics analysis revealed that nine of the significantly expressed proteins were enriched to 15 KEGG signaling pathways. These results suggest that the use of Western medicine non-surgical treatment for the LIDP without blood stasis can achieve satisfactory results. Besides, complement C1qA, cDNA protein (FLJ60724), complement C4B frameshift mutation, cDNA protein (FLJ53025), mannose binding protein C, apolipoprotein B, hemoglobin α-1 globin chain variant, hemoglobin β subunit and cDNA protein (FLJ76254) may be the potential serum markers of the non-surgical treatment for the LIDP without non-blood stasis.
