METHODS： Using stratified random sampling according to fibrinogen （Fib） levels, 145 liver cirrhosis patients due to hepatitis B complicated by coagulation disorder were treated. Of them, 70 in research group were treated with TCM by ＂nourishing yin, cooling blood and invigorating blood circulation＂ and Western medicine, 75 in control group were treated with conventional Western medicine. The indexes of liver function, coagulation function and bleeding events were observed and compared. RESULTS： The prothrombin time （PT） was shorter and the fibrinogen （Fib） level was higher in the research group than in the control group （Fib = 1.6-2.0 g/L, 1.1-1.5 g/L, and ≤ 1.0 g/L）. The total bilirubin （TBIL） level was significantly lower in the research group than in the control group, except for the subgroup of FIB ≤ 1.0 g/L. CONCLUSION： TCM therapy can improve coagulation fuction and decrease TBIL.展开更多
