while the control group had vitamin B1 100 mg and vitamin B12 250 μ g administered daily via intramuscular injection. The course for all patients was 28 days. The treated group experienced a therapeutic effect superior to that of the control group

with the difference between the total effective rates and the markedly effective rates (P<0.05

P<0.01). The blood levels of total cholesterol (TC) and triglyceride (TG) fell

the hemorrheological manner improved

the transmission velocity of the median nerve and common peroneal nerve signifi cantly increased in the treated group after treatment (P<0.05)

although the treatment showed no significant influence on blood glucose level (P>0.05). TLYYR could promote blood microcirculation
