Abstract:
Objective To explore the levels of serum matrix metalloproteinase-16(MMP-16)and growth differentiation factor-15(GDF-15)in elderly patients with tibial plateau fracture and its predictive value for postoperative deep veinous thrombosis(DVT).Methods A total of 107 elderly patients with tibial plateau fracture admitted to the First Affiliated Hospital of Gannan Medical University from February 2020 to Febru-ary 2024 were collected as study subjects.They were divided into DVT group(n=39)and non-DVT group(n=68)according to whether or not they had formed DVT at 7 d postoperative.The enzyme-linked immu-nosorbent assay was used to detect serum MMP-16 and GDF-15 preoperative,1 d postoperative and 3 d post-operative,and other clinical data of the study subjects were collected.Pearson correlation analysis was used to analyze the correlation between serum MMP-16,GDF-15 and venous thromboembolism risk assessment scale(Caprini)score.Logistic regression analysis was used to analyze the relationship between serum MMP-16,GDF-15 and postoperative DVT.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of the two indicators for postoperative DVT.Results The serum MMP-16 and GDF-15 level of two groups were first increased and then decreased at 1 d preoperative,1 d postoperative and 3 d postopera-tive(P＜0.05).Serum MMP-16 and GDF-15 levels were higher in DVT group than in non-DVT group at 1 d postoperative and 3 d postoperative(P＜0.05).Serum MMP-16,GDF-15 at 1 d postoperative and 3 d postop-erative were positive associated with Caprini score,respectively(both P＜0.05).Elevated Caprini score,ele-vated D-D,elevated serum MMP-16 and GDF-15 at 3 d postoperative were independent risk factors for DVT(OR=3.445,1.652,1.841,1.715,all P＜0.05).The area under the ROC curve of serum MMP-16,GDF-15 at 3 d postoperative and indicators combined to predict DVT was 0.798,0.792 and 0.895,respectively.The com-bined predictive value of indicators combined was greater than that of single indicator(Z=2.253,2.346,both P＜0.05).Conclusion Serum MMP-16 and GDF-15 expression are upregulated after tibial plateau fracture in elderly patients,which the indicators combined can predict the risk of DVT.
