Abstract: BACKGROUND: Previous studies have found that qi deficiency and blood stasis syndrome is the main syndrome among various TCM syndromes of cervical spondylotic myelopathy. However, there is no report on proteomic markers as early diagnosis indicators for the transformation of developmental cervical spinal stenosis with qi deficiency and blood stasis syndrome to cervical spondylotic myelopathy.
OBJECTIVE: To explore serum proteomics difference between developmental cervical spinal stenosis and cervical spondylotic myelopathy and to find and identify the potential serum biomarkers between them. 
METHODS: Serum samples of nine patients with cervical spondylotic myelopathy of qi deficiency and blood stasis syndrome (experimental group) and nine patients with developmental cervical spinal stenosis of qi deficiency and blood stasis syndrome (control group) were collected. The proteomic analysis was carried out by Tandem Mass Tag combined with liquid chromatography tandem mass spectrometry, so as to find and identify differentially expressed proteins.
RESULTS AND CONCLUSION: A total of 1027 significantly differential proteins were initially screened by TMT technology and 89 significantly differential proteins were finally identified (P < 0.05). Compared with the control group, there were 45 up-regulated proteins in the experimental group, such as α-actinin-4, α-actinin-1, cell division control protein 42 homolog, integrin-linked protein kinase and B-actin. Conversely, there were 44 down-regulated proteins in the experimental group compared with the control group, such as fibronectin, fibrinogen γ chain, fibrinogen α chain, fibrinogen β chain. Gene ontology enrichment analysis indicated that these differential proteins were involved in signal receptor binding, kinase binding, protein kinase activity, integrin binding, actin filament binding and other molecular functions. Based on the Kyoto Encyclopedia of Genes and Genomes pathway analysis, 20 common differential signal/metabolic pathways were identified, including Rap1 signaling pathway, adherens junction, tight junction, platelet activation, and regulation of actin cytoskeleton. Protein-protein interaction analysis showed that ILK, FGA, FGB, FGG, FN1, Cdc42, ACTN1, ACTN4 and ACTB were located at the nodes of protein-protein interaction network and were closely related to bone formation and destruction system, nervous system, coagulation system, cellular inflammation and other systems. To conclude, the serum differentially expressed proteins between developmental cervical spinal stenosis and cervical spondylotic myelopathy can be successfully screened by Tandem Mass Tag combined with liquid chromatography tandem mass spectrometry. ILK, FN1, CDC42 and ACTN 4 are identified as specific markers for the transformation of developmental cervical spinal stenosis with qi deficiency and blood stasis syndrome into cervical spondylotic myelopathy. These findings provide a basis for further clarifying the transformation mechanism.
