Objective: To investigate the correlation of thrombospondin-1(TSP-1) expression and angiogenesis and clinical pathologic factors in breast cancer. Methods:Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of TSP-1 mRNA in the primary breast cancer tissues and the tissues set apart 5 cm from the tumor. Im-munohistochemistry was used to detect the expressions of vascular endothelial growth factor (VEGF), c-erbB2, estrogen receptor (ER), progesterone receptor (PR) and microvessel density (MVD). All data were statistically analyzed. Results: The positive rate of TSP-1 was significantly higher in breast cancer than that in tissues set apart 5 cm from tumor (P < 0.05). The expression of TSP-1 was positively correlated with tumor size only (P < 0.05). MVD was lower in TSP-1 positive group than that of negative group (P< 0.05). Conclusion: The MVD was decreased with up-regulation of TSP-1 expression. Thrombospondin-1 may repress the angiogenesis in breast cancer.

Objective To explore the consistency and significance of optical coherence tomography (OCT) and clinical and histopathological findings in adoptively transferred uveitis in mice.Methods The adoptively transferred experimental autoimmune uveitis (EAU) model was established by intraperitoneal injection of antigen-specific T cells in C57BL/6 mice.Since 9 days after transferred,inflammation of eyes was observed by indirect ophthalmoscope with +90D lens and record clinical scores every 3 days.The disease was divided into 6 phases including onset phase,early phase,pre-peak phase,peak phase,resolution phase and late phase of EAU,which respectively corresponding to clinical score 0.5,1.0,1.5-2.0,2.5-3.0,1.0-2.0 and less than 1.0.Since 9 days after transferred,the retina and retinal thickness (RT) was measured by spectralis OCT about 1 disc from the disc edge in 10 time points including 9,11,16,21,25,30,35,40,50 and 60 days after transferred.The OCT score was recorded as from 0.0 to 4.0.After transferred 9,21 and 60 days,the mice were killed and eye balls were examined in histology.OCT score,clinical score and histology in the mouse were compared and analyzed.Results The disease was divided into onset phase,early phase,pre-peak phase and peak phase of EAU,which respectively corresponding to 9,16,21 and 26 days after transferred.In four phases,OCT score were 0.5,1.0,2.0 and 4.0 respectively.After transferred 30 days,which was in resolution phase of EAU,the inflammation cells in vitreous were decreased and OCT score was 3.0.After transferred 60 days,which was in late phase of EAU,inflammation cells in vitreous were disappeared and retina was atrophic topically.The histology showed the vitreous has slight inflammation cells and retinal structure was normal at onset of EAU.The vitreous has massive inflammation cells and retina structure was disorder at pre-peak of EAU.And in resolution phase of EAU,the inflammation cells in vitreous were slightly and retina was atrophic and thinned.The data in this study demonstrated that OCT score was well correlated with clinical score in EAU (r=0.957 9,P＜0.000 1).Conclusion OCT and clinical and histopathological findings in adoptively transferred uveitis in mice were consistency and OCT is contribute to evaluate the disease dynamically and quantifiably.

Objective To observe the effects of Suhuang Zhike capsules(SZC) on the guinea pig model of cough variant asthma(CVA), and to explore its therapeutic mechanism. Methods Fifty guinea pigs were randomly divided into normal control group, model group, prednisone acetate tablets group, and high-and low-dose SZC groups. With reference to the related literatures, we set up the guinea pig model of CVA. The observation indexes included cough frequency, lung histopathology, the percentage of eosinophils in bronchoalveolar lavage fluid (BALF), and the serum levels of interleukin 4(IL-4), interferon gamma(IFN-γ), tumor necrosis factor alpha (TNF-α), and immunoglobumin E(IgE). Results Compared with the normal control group, the cough frequency of the model group was significantly increased(P<0.05); compared with the model group, the cough frequency of high-dose SZC group was reduced obviously(P < 0.05). Compared with the normal control group , the percentage of eosinophils in BALF of the model group was significantly increased(P < 0.05); the percentage of eosinophils of the three medication groups was lower than that of the model group (P<0.05). The pathological changes of lung tissue in the medication groups were relieved compared to the model group. Compared with the normal control group, the serum IL-4, TN F-α and IgE levels of the model group were increased significantly (P < 0 . 05); compared with the model group , the serum IL-4 and TN F-α levels of prednisone acetate tablets group were significantly decreased, and the serum TNF-α and IgE levels of high-dose SZC group were decreased significantly (P < 0.05). Conclusion SZC could reduce the serum, TNF-α and IgE levels , and relieve the cough symptom, airway inflammation and the lung tissue pathology in CVA guinea pig, so as to achieve the therapeutic effect on CVA.
