Objective To discuss how to use the core elements of international classification of functioning,disability and health(ICF) as a guide in stroke operation treatment to develop targeted,effective therapy plan and rehabilitation goals,establish individualized treatment of rehabilitation,and to observe the effect of limb movement function in stroke patients. Methods Sixty cases patients with stroke and aged from 40 to 65 years old were selected. The body function and structure of all stroke patients were marked by comprehensive evaluation scores of The National Institutes of Health Stroke Scale ( NIHSS ) and Fugl?Meyer assessment. And then they were randomly divided into two groups,30 cases in each group. The observation group used the Chinese version of brief ICF Core Sets for evaluation, and set individualized treatment according to the results of the assessment;The control group, according to the conventional rehabilitation process, involved in training routine physical therapy. Again 8 weeks after treatment for patients with evaluation,the assessment results was compared with the results of the first assessment. Results Before treatment, the NIHSS, Fugl?Meyer assessment and Chinese version of brief ICF core elements scale scores for the observation group were 7. 95±2. 37,34. 5±4. 0 and 82. 15±17. 96,for the control group were 7. 58±2. 25,34. 8±4. 0 and 81. 55±18. 78. After treatment,the above three rating scale scores, for the observation group were improved to 4. 78 ± 1. 63, 56. 3 ± 4. 2, 60. 45 ±11. 04,for the control group were improved to 5. 13±1. 75,48. 1±3. 8,73. 56±16. 89. The two groups were significantly improved ( observation group:t=4. 94, 15. 51, 18. 59, P<0. 05;control group:t=3. 17, 14. 66, 12. 33,P<0. 05). After treatment,compared with the control group of three rating scale scores(5. 13±1. 75,48. 1
±3. 8 and 73. 56±16. 89),the observation group(4. 78±1. 63,56. 3±4. 2 and 60. 45±11. 04) improved more apparently(t=3. 15,14. 54,15. 45,P<0. 05) .

Objective To establish a HPLC method for the assay of psoralen and isopsoralen in different effective extracts of Fructus Psoraleae. Methods HPLC was carried out on the column of Kromasil RP-C18. The mobile phase was methanol -water(65 ∶35). The flow rate was 1.0 mL/min and the UV detection wavelength was 245 nm. Results Good linearity of psoralen was showed within the range of 10.5 ng～525 ng(r= 0.999 3)and isopsoralen within the range of 9 ng～450 ng (r= 0. 999 9). The content of psoralen and isopsoralen differed in different extractions of Fructus Psoraleae. Among them,the extract C (extracted by ethyl acetate ) contained the highest contents of psoralen and isopsoralen,while the contents of psoralen and isopsoralen were very low in the extract D (extracted by n-butyl alcohol) and E (supernatant of water extract). Conclusion The method is simple,accurate and reproducible. The anti-asthma effect and the dose-effect relationship of the different effective extracts of Fructus Psoralea need further pharmacodynamics study.
