Objective: To research the effect of Qiangyuan Shenghua decoction on lymphocyte level of patients with posttraumatic sepsis. Method: Eighty-eight patients with posttraumatic sepsis were randomly divided into treatment group and control group. Patients in control group were treated with conventional western medicine and pure water

and patients in the treatment group were treated with Qingyuan Shenghua decoction in addition to the conventional western medicine therapy. The white blood cell count (WBC)

the number of neutrophils (NEU)

neutrophil percentage (NEU%)

total lymphocyte count (TLC)

total lymphocyte percentage (TLC%) and C-reactive protein (CRP) and calcitonin original (PCT) in venous blood of all the patients were detected on the 1st

3rd and 7th day before and after treatment

and the mortality was also observed on the 7th day after treatment. Result: The difference on WBC

TLC

NEU

NEU%

CRP and PCT between the two groups before and after treatment was not significant. After a day's treatment

the TLC in the treatment group was significantly different from before the treatment (P<0.05). After 3 day's treatment

the WBC

CRP and PCT of patients in treatment and control group were significantly different from before the treatment (P<0.05)

and the WBC

TLC and TLC%

CRP and PCT in the treatment group were significantly different from that of the control group (P<0.05). After 7 day's treatment

all of the indexes of patients in treatment and control group were significantly different from before the treatment (P<0.05) and that of the control group (P<0.05). The mortality of treatment group was less than that of control group (P<0.05). Conclusion: Qiangyuan Shenghua decoction could improve the lymphocyte level and lymphocyte ration

and the prognosis was favorable.
