Results:Positive cells were found on 13 of 250(5.20%)cores,and 7 of 250(2.80%)stylophores.The difference was not sta- tistically significant(P>0.05).The positive cells frequency of needles those traversed distance less than 3 cm in normal tissue was 6.19%(13/210),while the frequency of the others those traversed longer distance in normal tissue was 2.41%(7/290). The positive cells frequency of needles traversing different distances in normal tissues is significantly different(P<0.05).No neoplasm was detected through needle tracks by ultrasound B-mode or CT in 180 days after operation.Conclusion:Tumor cells could ablate into the needle track during radioactive seed implantation.Some preventive measures,such as optimization of pre-operation and intra-operation treatment plan,chemotherapy or endocrine therapy after operation,may be beneficial to avoid the implantation metastasis of neoplasm in seeding needle tracks.展开更多

In the preventive treatment of diseases, the ancient Chinese doctors usually (1) regulated qi of both Conception Vessel and Governor Vessel for health care; (2) performed regular moxibustion; and (3) applied plaster to the acupoint in summer for treating winter-diseases. In the treatment of diseases after onset, the ancient Chinese usually (1) tried best to make early diagnosis and early treatment; and (2) strengthened the related internal organ in advance to check their development; and (3) employed appropriate remedies to recuperate the patient's health.展开更多
