ABSTRACT
It was generally believed that muscular atrophy of paralyzed limbs after stroke was due to disuse. However, recent studies have found that secondary lesions of motor neurons in the contralateral anterior horn of the spinal cord and the decrease of motor units lead to denervation, which plays an essential role in muscular atrophy and muscle fiber type transition. This article reviews the phenomenon and mechanism of muscular atrophy and denervation of paralyzed limbs after stroke, to provide a reference for clinical evaluation and experimental research.
ABSTRACT
Objective To observe the effect of spleen-strengthening and kidney-reinforcing method on leukopenia in patients with malignant tumor after chemotherapy.Methods Seventy-one patients with malignant tumor were randomly allocated to Group A(n=37) and Group B (n=34).Group A was treated with spleen-strengthening and kidney-reinforcing herbal medicine and chemotherapy and Group B with chemotherapy only. The treatment course lasted 28 days.Blood routine examination was carried out before chemotherapy and on 7 th,9 th,12 th,15 th,18 th and 21 st day of chemotherapy.Results In Group A,5 cases of leukopenia were found, 3 in degree Ⅰ, 1 in degree Ⅱ and 1 in degree Ⅲ,the incidence being 13.5%; In Group B,25 cases of leukopenia were found, 3 in degree Ⅰ,13 in degree Ⅱ,8 in degree Ⅲ and 1 in degree Ⅳ, the incidence being 73.5%. There was significant difference between the two groups (P
