Objective:To probe into laboratory indexes of TCM blood stasis syndrome of diabetic peripheral neuropathy（DPN） and significance of syndrome objectivity.Methods:DPN patients were divided into 3 groups:group Ⅰ（blood stasis syndrome）

group Ⅱ（Non-blood-stasis syndrome）

Group Ⅲ（no-complication and non-blood-stasis syndrome） with group Ⅳ（normal group） used as controls.Other diabetic vascular complications

TCM symptoms

picture of the tongue

pulse condition in the group Ⅰ

Ⅱ and Ⅲ

and blood sugar

glycosylated hemoglobin

hemorheological indexes

nail fold microcirculation

blood lipids and fundus examination in the 4 groups were investigated and the results were compared.Results:Most patients of DPN blood stasis syndrome were complicated by other vascular diseases.Clinically

numbness（86.1%）

dark tongue proper（100%） and pale tongue proper（80.6%） were most commonly seen

and the abnormal rates of hemorheological indexes

nail fold microcirculation

blood lipids and optical fundus in the DPN blood stasis group were higher than those in other groups（P<0.05 or P<0.01）.Conclusion:DPN blood stasis syndrome is most closely related with abnormality of hemorheological indexes

nail fold microcirculation

blood lipids and optical fundus.
