Comparative analysis of methods for concentrating venom from jellyfish Rhopilema esculentum Kishinouye

In this study, several methods were compared for the efficiency to concentrate venom from the tentacles of jellyfish Rhopilema esculentum Kishinouye. The results show that the methods using either freezing-dry or gel absorption to remove water to concentrate venom are not applicable due to the low concentration of the compounds dissolved. Although the recovery efficiency and the total venom obtained using the dialysis dehydration method are high, some proteins can be lost during the concentrating process. Comparing to the lyophilization method, ultrafiltration is a simple way to concentrate the compounds at high percentage but the hemolytic activities of the proteins obtained by ultrafiltration appear to be lower. Our results suggest that overall lyophilization is the best and recommended method to concentrate venom from the tentacles of jellyfish. It shows not only the high recovery efficiency for the venoms but high hemolytic activities as well.

Effects of Moxibustion Therapy on Preventing and Treating Side Effects from Chemotherapy of Malignant Tumor Patients

Objective： To observe the clinical effects of moxibustion therapy on preventing and treating toxic and side effects of chemotherapy in malignant tumor patients. Methods： A total of 63 cases were randomly divided into three groups. Twenty-three cases in the moxibustion group were treated by moxibustion, and 22 cases in the hydro-acupuncture group were treated by acupoint injection, and 18 cases in the control group were treated by oral administration of Batilol tablets. The changes of the white blood cell count and the content of immunoglobulin before and after the treatments were observed. Results： After treatments, the total leukocyte count and the content of immunoglobulin were all elevated in the moxibustion group and the hydro-acupuncture group, with statistical difference when compared with the control group （P〈0.05, P〈0.01）. In the elevation of the white blood cell count, the hydro-acupuncture group was better than the moxibustion group （P〈0.05）. Conclusion： Moxibustion and hydro-acupuncture can be used to treat and prevent toxic and side effects of chemotherapy. From this aspect, the different needling techniques possess different effects.

Continuous Method Development and Numerical Study of HHV Water Gas Production by Pulverized Coal

In energy industries, it is always of difficulty to produce high heat value（HHV） gas continuously using pulverized coal. In this paper, a new type furnace for partitioned alternative gasification using pulverized coal is developed, in which the oxidation and reduction reaction occur alternatively with the dropping of pulverized coal and finally HHV gas could be continuously obtained at the reduction zone exit and low heat value（LHV） gas at the oxidation zone exit. Furthermore, the gasification characteristics and their factors in furnace are numerically simulated under two dimensional model with a self-coded program, based on heat, mass and energy transfer as well as reaction principles. It is found that the producing rate of HHV gas is 1.10Nm3/kg with heat value of ll.72MJ/Nm3, how- ever, that of LHV gas is 2.58Nm3/kg with heat value of 5.30MJ/Nm3, and the coal gas efficiency is 81.16% under optimized conditions.
