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.

MAGNETIC STIMULATION TO THE LUMBOSACRAL REGION AND ITS APPLICATION IN DIAGNOSIS OF LUMBAR DISC HERNIATION

In this paper, motor root conduction time (MRCT) was determined by the magneticstimulation in lumbosacral region with F wave elicited by the same method in popliteal fossa. Motornerve conduction time (MNCT) and MRCT were determined on tlhlalls and soleds. With MRCT theexciting point arter magnetic simulation over lumbosacral vertebral column could be round. Togetherwith the lengths or LS and SI root determined in 5 autopsies the exciting site is located in the intervertebral roramen berore the exit or the root. MNCT and MRCT were determined in 40 I,atients withiumhar disc herniation by the method with control. The result showed that no difrerence was seen inMNCT In all ~lents. It is concluded that magnetic stimulation of MEPs is an useful teckulque fornon-invaslve diagnosis of lumber disc kerniation.

Root microbiota shift in rice correlates with resident time in the field and developmental stage

Land plants in natural soil form intimate relationships with the diverse root bacterial microbiota. A growing body of evidence shows that these microbes are important for plant growth and health. Root microbiota composition has been widely studied in several model plants and crops; however, little is known about how root microbiota vary throughout the plant's life cycle under field conditions. We performed longitudinal dense sampling in field trials to track the time-series shift of the root microbiota from two representative rice cultivars in two separate locations in China. We found that the rice root microbiota varied dramatically during the vegetative stages and stabilized from the beginning of the reproductive stage, after which the root microbiota underwent relatively minor changes until rice ripening. Notably, both rice genotype and geographical location influenced the patterns of root microbiota shift that occurred during plant growth. The relative abundance of Deltaproteobacteria in roots significantly increased overtime throughout the entire life cycle of rice, while that of Betaproteobacteria, Firmicutes, and Gammaproteobacteria decreased. By a machine learning approach, we identified biomarker taxa and established a model to correlate root microbiota with rice resident time in the field(e.g., Nitrospira accumulated from 5 weeks/tillering in field-grown rice). Our work provides insights into the process of rice root microbiota establishment.
