Abstract:
BACKGROUND:The correlation between blood stasis syndrome and non-blood stasis syndrome of lumbar intervertebral disc protrusion remains unclear.
OBJECTIVE:To construct serum protein pattern model for diagnosing blood stasis syndrome of lumbar intervertebral disc protrusion.
METHODS:A total of 180 cases were included in this study and divided into treatment group (120 patients with lumbar intervertebral disc protrusion) and control group (60 healthy cases from physical examination). Furthermore treatment group was equal y assigned into blood stasis syndrome subgroup and non-blood stasis syndrome subgroup, with 60 cases in each subgroup. The involved cases were wel matched in nations, genders and ages. Serum samples of peripheral blood from the 180 cases were col ected. Surface-enhanced laser desorption/inionation time of flight mass spectrometry and ProteinChip technology were employed to detect and plot protein mass spectrum. The protein peak values were identified using Biomarker Wizard software. Then serum diagnosis model of blood stasis syndrome of lumbar intervertebral disc protrusion was established. The obtained models were verified through double blind method. The differential proteins were searched by ExPASy data.
RESULTS AND CONCLUSION:We detected that peak values of eleven proteins had statistical significance (P<0.05) from the involved 180 cases. Among them, two proteins were highly expressed while the other nine proteins were lowly expressed. Serum protein pattern model for diagnosing blood stasis syndrome of lumbar intervertebral disc protrusion was established through Biomarker Patterns software, and the sensibility was 86.667%, the specificity was 94.167%, the positive predictive value was 88.136%. There are a variety of abnormal y expressed proteins in the serum of the patients with blood stasis syndrome of lumbar intervertebral disc protrusion. The serum protein pattern model involved eleven different proteins can be used to diagnose blood stasis syndrome of lumbar intervertebral disc protrusion.
