CLINICAL STUDY ON THE TIME OF TREATING CHEMOTHERAPY INDUCED TOXIC AND SIDE EFFECTS IN MALIGNANT TUMOR PATIENTS BY ACUPOINT INJECTION OF ASTRAGALUS ROOT INJECTION

Objective: To investigate the suitable time of treating virulent and side effects of chemotherapy for malignant tumor by acupoint injection of Astragalus Root injection. Methods: Sixty three patients with malignant tumor were divided into three groups: prevention treatment (PT) group (n=23 cases),post chemotherapy treatment (PCT) group( n=22 cases), Western medicine (WM) group ( n=18 cases). The patients in PT, PCT and WM groups were treated respectively from the fifth day on before chemotherapy and from the first day on after chemotherapy, 18 days in all. The patients in WM group were administered Batilol and Leucogen from the first day on after chemotherapy. Changes of leukocytes and immunoglobulin before and after treatment were observed. Results: 1) Acupoint injection of Astragalus Root injectio could increase the number of leukocytes and immunoglobulin content and its effect was better than that of Western medicine (P<0.05); 2) The effect of PT group was better than that of PCT group in preventing and treating virulent and side effects of chemotherapy (P<0.05). Conclusion: It should be stressed on prevention of malignant tumor by using acupoint injection of Astragalus Root for relieving virulent and side effects of chemotherapy.

Effective root depth and water uptake ability of winter wheat by using water stable isotopes in the Loess Plateau of China

A field experiment using PVC growth tubes was conducted in the Loess Plateau of China to determine the effective root depth(ERD)of winter wheat and its relationship with root distributions and soil water conditions.The water stable isotopes technique was used to estimate the water uptake contributions of different root depths during the growth stages.On the basis of IsoSource and the Romero-Saltos model,the ERD was 0-40 cm in the majority of the growth stage.However,in the heading and filling stages,the ERD could reach 60%-75%of the maximum root depth.Furthermore,the contributions to water uptake of different root depths were correlated with variations in soil water and root length density(r=0.395 and 0.368,respectively;p<0.05).However,by path analysis,the low decisive coefficient indicated that root distribution and soil water content did not always follow the same trend as water uptake.The conclusions of this study can help with understanding winter wheat water uptake mechanisms in arid and semi-arid regions and increasing water use efficiency.
