ABSTRACT
Objective:To investigate the expression levels and diagnostic value of platelet parameters, fibrinogen and D-dimer in different Traditional Chinese Medicine (TCM) syndromes of deep venous thrombosis (DVT).Methods:From June 2015 to June 2019, a total of 500 DVT patients were enrolled and collected by two attending TCM doctors and classified according to syndromes differentiation. The differences of platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), platelet crit (PCT), platelet larger cell ratio (P-LCR), fibrinogen (FIB) and D-dimer were detected and compared.Results:According to TCM syndromes differentiation, 500 patients were divided into three groups, including 286 cases (57.2%) of downward flowing of damp-heat group, 132 cases (26.4%) of blood stasis and heavy damp group, and 82 cases (16.4%) of spleen-kidney-yang deficiency group. The levels of MPV, PDW, P-LCR, FIB and D-dimer among the groups were statistically significant difference ( P<0.05 or P<0.01). The MPV level was significantly higher and D-dimer level was significantly lower in blood stasis and heavy damp group than in the downward flowing of damp-heat group ( P<0.05). The levels of MPV, PDW and P-LCR in spleen-kidney-yang deficiency group were significantly higher than those in downward flowing of damp-heat group and blood stasis and heavy damp group ( P<0.05 or P<0.01). The levels of FIB and D-dimer were significantly lower than those in the downward flowing of damp-heat group and blood stasis and heavy damp group ( P<0.05 or P<0.01). The FIB (AUC=0.593) and D-Dimer (AUC=0.673) were statistically significant in the differential diagnosis of DVT between blood stasis and heavy damp group and spleen-kidney-yang deficiency group ( P<0.01). The MPV (AUC=0.601 5), PDW (AUC=0.615 4), P-LCR (AUC=0.606 1), FIB (AUC=0.616 4) and D-Dimer (AUC=0.721 8) were statistically significant in the differential diagnosis of DVT between downward flowing of damp-heat group and spleen-kidney-yang deficiency group ( P<0.01). Conclusion:The MPV, PDW, P-LCR, FIB and D-dimer have a certain correlation with DVT TCM syndrome types, and also have a certain reference value for its differential diagnosis, which can be used as an effective supplement to the objective indicators of Micro syndrome differentiation of traditional Chinese medicine.
