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.

Experimental and numerical study of tip injection in a subsonic axial flow compressor

Parametric study of tip injection was implemented experimentally on a subsonic axial flow compressor to understand the underlying flow mechanisms of stability improvement of the compressor with discrete tip injection.Injector throat height varied from 2 to 6 times the height of rotor tip clearance,and circumferential coverage percentage ranged from 8.3% to 25% of the annulus.Static pressure fluctuations over the rotor tip were measured with fast-response pressure transducers.Whole-passage time-accurate simulations were also carried out to help us understand the flow details.The combinations of tip injection with traditional casing treatments were experimentally studied to generate an engineering-acceptable method of compressor stall control.The results indicate that the maximum stability improvement is achieved when injectors are choked despite their different sizes.The effect of circumferential coverage percentage on compressor stability depends on the value of injector throat height for un-choked injectors,and vice versa.Tip blockage in the blade passage is greatly reduced by the choked injectors,which is the primary reason for stability enhancement.The accomplishment of blockage diminishment is maintained in the circumferential direction with the unsteady effect of tip injection,which manifests as a hysteresis between the recovery of tip blockage and the recovery of tip leakage vortex.The unsteady effect is primarily responsible for the effectiveness of tip injection with a partial circumferential coverage.Tip injection cannot enhance the stability of the rotor with axial slots significantly,but it can improve the stability of the rotor with circumferential grooves further.The combined structure of tip injection with circumferential grooves is an alternative for engineering application.
