ObjectiveTo evaluate the efficacy of the high-flux dialysis on maintaining hemodialysis patients. Methods60 hemodialysis patients were randomly divided into the ordinary PMMA membrane dialyzer group,the ordinary polysulfone membrane dialyzer group and the high-flux dialyzer group with 20 patients in each group.Before and after the single hemodialysis,the removing effect of serum β2- microglobulin (β2-MG)in the 3 kinds of dialyzer,and cholesterol,triglyceride,low density lipoprotein changes after 6 months were compared. ResultsThe ordinary PMMA membrane dialyzer group and high-flux dialyzer group can reduce the concentration of β2-MG,while the high-flux dialyzer group showed more significant effect.On the aspect of lipid metabolism,in the high-flux dialyzer group,serum total cholesterol,triglycerides and LDL levels decreased significantly,while the ordinary dialysis group had no significant change. ConclusionsThe high-flux dialysis can improve the dialysis efficiency,life quality and reduce the complications of patients.

ve To study the growth curve of Alexandrium tamarense and the toxicity of paralytic shelfish poisoning(PSP) selected in different growth phases, as well as to quantitatively analyze the toxins and compare the different efficiency of breaking cell wall and their virtues and defects between freezing-thawing method and supersonic method, and to provide theoretical basis for the selection of the methods for extraction of PSP. Methods Cells were collected by suction filter, cell wall was broken by freezing-thawing method and supersonic method, the toxicities of Alexandrium tamarense among different growth phases were detected and compared. Results The growth of Alexandrium tamarense typically showed three phases which included a lag phase(0~9 days), an exponential growth phase(10~18 days), and a stationary phase(19~22 days) . The maximum toxicity of cells in the stationary phase appeared, especially in day 21 when the population of cells reached to 9.43?10-6 MU/cell, although the cells in the exponential phase grew fastest. Toxicity of the cells in the lag phase broken by freezing-thawing method was more stronger than that by supersonic method, that meant the toxicity of cells was lowered after the supersonic treatment. In additional, the filtering method for collecting cells presented a lower recovery rate of average 69.0% . Conclusion As for the comparing of freezing-thawing method and supersonic method, it was found that, when cells were in the same phase, the supersonic method had remarkable advantages, but it also had the disadvantage of lowering the tox-icity of cells. When in the same condition of growth and method of fragmentation, cells in the lag phase were broken most easily, and cells in the stationary phase were more difficult to be broken than those in the other two phases. Toxicity of cells was larger and larger with the time of incubation. The toxicity of cells in the lag phase had reached a higher intensity, although toxicities of cells in the next two phases would increase a little.

Objective To Analyze the imaging characteristics of intraparenchymal schwannoma and the related pathology,in order to improve the accuracy of diagnosis and be in favor of the clinics and the prognosis.Methods Four cases were confirmed to be intraparenchymal schwannoma by pathological and immunohistochemistry examination.One case was examined with precontrast and enhanced CT scanning,one with unenhanced MRI scanning,two with unenhanced and enhanced CT and MRI scanning.Their images were retrospectively analyzed.Results Of the four cases,three patients were less than 30 years old,with tumors located supratentorially.Cysts were found in all cases,with nodules on the wall in 3 cases.The nodules were enhanced markedly in two cases and moderately in one ease.In addition,calcification was detected in one case and prominent peritumoral edema existed in 1 case.The picture of the pathology demonstrated Antoni type A and Antoni type B.Immunostaining showed intense immunoreactivity for S-100 protein and Vim and negative immunoreactivity for GFAP and EMA.Conclusions Intraparenchymal schwannoma mostly occurred in juvenile,which located supratentorially in most cases.The presence of a cyst and peritumoral edema together with the tumor appears to be characteristic of intraparenchymal schwannoma.Calcification or the enhanced nodule is the helpful sign for the diagnosis.Combining the imaging findings with the pathology and immunohistochemistry results can gain the accurate diagnosis.

Objective To investigate the relationship between the expression of p63, p73 proteins and the development of hemangioma. Methods The immunohistochemical technique and quantitative image analysis were used to detect the expression of p63 and p73 proteins in 40 cases of capillary hemangioma and 20 specimens of normal skin. Results The absorbance value (mean ? SD) of p63 and p73 expression in normal skin tissue, proliferative phase of hemangioma and involuting phase of hemangioma were 0.923 ? 0.191 and 0.953 ? 0.120, 8.271 ? 1.953 and 6.408 ? 2.151, 0.920 ? 0.187 and 1.073 ? 0.516, respectively. The expression of p63 and p73 in proliferative phase of hemangioma was significantly increased as compared with those in involuting phase of hemangioma and normal skin tissue (P 0.05). Conclusions It is suggested that p63 gene is not a tumor suppressor gene but an oncogene in hemangioma and may contribute to the proliferation of endothelial cell and be associated with angiogenesis, and p73 may play an important role in the proliferation of hemangioma.
