They were divided into the ICWM group (29 patients) and the western medicine (WM) group (22 patients). Western medical treatment was applied to both groups, but to the ICWM group, Ch inese medicine was given additionally. The therapeutic course was 2-3 weeks for both groups. Clinical effect and changes of T lymphocyte subsets (CD4 +) aft er treatment were observed.Results: In the ICWM group, 26 patients (89.66%) were cured and 3 (10.34%) died, while in the WM group, 12 (54.55%) cur ed and 10 (45.45%) died, thus comparison of the cure rate between the two groups showing significant difference ( P <0.01). The score of clinical symptoms in the ICWM group was decreased from 7.14±5.20 scores before treatment to 1.82±3. 75 scores after treatment, while in the WM group, it lowered from 7.36±3.84 sco res before treatment to 5.17±4.17 scores after treatment, significant diffe rence shown in the comparison of the values between the two groups after treatme nt (P<0.01). Immunological function test showed that CD4 + T lymphocyte in the ICWM group rose from 361±278 cells/mm 3 before treatment to 630±454 c ells/mm 3 after treatment, showing significant difference( P <0.01 );bu t in the WM group, it merely rose from 288±186 cells/mm 3 to 376±285 cells/mm 3 in the corresponding period (P>0.05). Conclusion: ICWM could improve the clinical symptoms of SARS pa tients markedly, enhance their T lymphocyte immune function, and reduce their mortality.展开更多
