SERPINE1 and deep vein thrombosis: The present study found that the levels of peripheral inflammatory factors in the observation group were higher than those in the control group, and the correlation analysis between serum inflammatory factors and blood coagulation factors showed that the levels of CRP, IL-6, IL-10 and PAI-1:Ag level were positively correlated, indicating that the higher the level of inflammatory cytokines in serum, the greater the risk of DVT, which is consistent with most of the findings.
