Abstract: In order to probe into the effects of self-controlled exercising on lymphocyte subsets in malignant tumor patients after surgery, the authors selected 40 new students (17 male students and 23 female students) from Shanghai Cancer Rehabilitation School as their test subjects, whose average age was 57.50±6.84, whose average cancer age was 1.50±0.77. The types of sickness were respectively digestive system cancer, breast cancer, other types of ma-lignant tumors (lung cancer, ovarian cancer etc). Guided by specialists, the patients learnt self-controlled exercising for 3 weeks, and then maintained self-controlled exercising for 24 weeks, at an average exercising frequency of 5 days a week, and a daily exercising duration of 2 hours. The authors tested the contents of cells CD3+, NK and NKT in the peripheral blood of the patients before the experiment, in weeks 12 and 24 respectively, and revealed the fol-lowing findings: 1) in week 24 after the experiment, the content of lymphocyte CD3+ increased significantly (P<0.01); 2) in week 12 after the experiment, the content of cell NKT increased significantly (P<0.05), and in week 24, it was significantly higher than that measured before the experiment (P<0.01) and that measured in week 12 (P<0.05) respectively; 3) in week 12 after the experiment, the content of NKT was significantly higher than that measured before the experiment (P<0.05), and in week 24, it showed a trend of decreasing as compared with that measured in week 12 (P>0.05), but it was still slightly higher than that measured before the experiment (P>0.05); 4) before and after the experiment, the contents of cells CD3+, NK and NKT had no between group difference (P>0.05). The said findings indicated that self-controlled exercising can improve the rates of expression of cells CD3+, NK and NKT in peripheral blood during the rehabilitation period of malignant tumor patients, is conducive for a tumor patient’s body immunity to monitor and immunely kill the exertion of tumor cell functions. The authors also found that there was no difference in type of cancer between cells CD3+, NK and NKT in the peripheral blood of malignant tumor patients.
