The mesoporous manganese dioxide (MnO2) materials were synthesized by the calcinations of manganese carbonate (MnCO3) precursors in air atmosphere at 300, 350 and 400℃. The slurries of MnO2 and binder were sprayed on the quartz electrodes. Quartz crystal microbalance (QCM) was conducted with cyclic voltammetry to analyze the electrochemical behaviors of the three MnO2 samples in 0.1 mol/L sodium sulfate (Na2SO4). The mass of the three samples were generally increased during potential cycling, especially in the first stage, which suggested that an irreversible reaction process occurred. The as-synthesized MnO2 at 300℃ had the better electrochemical stability and capacity retentivity. The three materials were assembled to (-) active carbon/MnO2 (+) supercapacitors and the charge-discharge tests were conducted. The results showed that 35％-40％ capacity loss was occurred in the initial cycling, and the total discharge capacities of MnO2 formed at 300℃, 350℃, 400℃ were 15.9, 12.9, 11.7 mA h/g, respectively. The detection results of QCM method were consistent with that of the charge-discharge tests, suggesting that this QCM method could be used for distinguishing the electrochemical performance of mesoporous MnO2 materials.

Glycogen storage disease (GSD) is a rela-tively rare inherited metabolic disease. However, its relative rarity implies that no metabolic centre has experience of large numbers of patients and experience with long-term manage-ment is limited. In addition, there is wide variation in meth-ods of medical treatment. With the development of medical care, life-expectancy in glycogen storage disease (GSD) has improved considerably. With ageing liver adenoma may de-velop which will bring about several complications-compres-sion, hemorrhage, or even transformation into carcinomas-and needs immediate intervention. In this paper, reviews for the mechanism and surgical intervention of GSD are presented.

Objective To analyze the relationship between genetic variability and evolution among Trypanosoma brucei (including T. b. brucei, T. b. rhodesiense and T. b. gambiense), T. evansi and T. equiperdum isolates. Methods Genomic DNAs of 26 trypanosome isolates were amplified by a mobile genetic elements (MGE)-PCR technique and cluster analysis was performed based on the molecular profiles with Neighbor-Joining method. Results The genetic variability among trypanosome isolates examined was obvious with an average genetic distance of 41.2% (ranged from 0 to 100%). Similarity coefficient among T. brucei isolates was 41.15% which was lower than that between T. evansi and T. equiperdum isolates. The closest relationship was found between T. evansi and T. brucei isolates with a similarity coefficient of 62.94%. The genetic variability between T. b. rhodesiense and T. b. brucei isolates was higher than that among T. b. gambiense isolates. Conclusion Species and subspecies in Trypanozoon displayed a higher genetic variability; T. equiperdum isolates collected from China and from South America, and T. evansi isolates from China and from South America, should have a similar origin.
