Organics of the phthalocyanine category have very good nonlinear optical properties. The single-walled carbon nanotubes were modified by using the phenoxy phthalocyanine. Characterization analysis was made by means of the transmission electron microscope (TEM), ultraviolet visible absorptive spectra, fluorescent spectra and Raman spectra. Under the TEM, it was observed that the composite looked like sugarcoated haws. By comparing the ultraviolet visible absorptive spectra before and after absorption, it was disclosed that the spectral intensity and the intensity of the peaks in the fluorescent spectra dropped remarkably. This shows that the single-walled carbon nanotubes have absorbed a large number of phenoxy phthalocyanines. Raman analysis revealed that in the Raman spectra, the position of the main peaks of the single-walled carbon nanotubes after absorption moved in the direction of long waves. The analysis suggests that the movement of the Raman spectra results from the change in the state of the single-walled carbon nanotubes before and after absorption.

Objective To investigate the role of SCF on neuronal apoptosis induced by diabetes and its possible mechanism.Methods Twenty-seven male C57 mice were randomly divided into control group,diabetes group,and diabe-tes plus stem cell factor(SCF)group.The diabetic mice were induced by streptozotocin.TUNEL staining was used to assess neuronal apoptosis and western blot were used to detect the protein level of BCL-2,BAX,CASPASE 3 and P-ERK/ERK.Results Compared with the controls,the number of apoptotic neuron death and the protein levels of active CASPASE 3 were significantly increased in the cortex of diabetic mice.Treatment with SCF significantly reduced apoptotic neuron death and attenuated the increased in protein levels of active CASPASE 3 in the cortex of diabetic mice.The levels of BCL-2 and BAX were significantly increased in the diabetic animals compared to the controls.Treatment with SCF could significantly attenuated the increase in the expression of BAX but could not affect the level of BCL-2 in the cortex of diabetic mice.P-ERK was significantly decreased in the diabete group but not in dibete plus SCF group.Conclusions SCF can protect a-gainst diabete-induced apoptotic neuron death through increasing the phosphorylation of ERK and influencing the expression of BCL-2/BAX.

Objective To investigate the effects of Working Memory Training System on working memory impairment after brain injury. Methods From November, 2013 to March, 2015, 20 patients of brain injury with impairment of working memory were divided into training group (n=10) and control group (n=10). The training group was trained with the Working Memory Training System for four weeks, while the control group did not accept any cognitive rehabilitation. They were tested with digital forwards/backwards, space forwards/backwards, n-back test and Everyday Memory Questionnaire before and after training. Results All of the tests improved more in the training group than in the control group (Z>2.014, P<0.05), except that of digital forwards, as well as the score of Everyday Memory Questionnaire (Z=1.970, P=0.049). Conclusion Application of Working Memory Training System can improve the ability of memory in patients with brain injury, both the working memory and everyday memory.

Objective To study the imaging features of primary mediastinal cysts,and to improve the diagnostic ability of these diseases.Methods The imaging findings of primary mediastinal cysts proved by pathlolgy in 42 cases were retrospectively.All of cases underwent posteroanterior and lateral views of chest.The plain and contrast-enhanced CT scans were performed in 28 and 15 cases.MRI examination was done in 6 cases.The location,size,shape,density,edge,wall and adjacent structures of the primary mediastinal cysts were observed.According to imaging features all of cases was divided into typical group and atypical group.Results The mediastinal cysts were located in anterior mediastinum in 28 cases,in middle mediastinum in 7 cases,in posterior mediastinum in 7cases.Bronchogenic cyst was in 9 cases.Cystic lymphangioma was in 4 cases.Thymic cyst was in 11 cases.Pericardial cyst was in 5 cases.Mature cystic teratoma was in 13 cases.The typical group was in 38 cases.The atypical group was in 4 cases.Conclusion 90% of the typical primary mediastinal cysts can be diagnosed.The final diagnosis of the atypical group desponds on pathology.
