RESUMO
Objective: To carry out telemedicine, remote teaching and conference, training and other activity by using remote medical information service platform based on Internet of Things so as to help primary hospital and clinic to achieve trans-regionally medical rescue and medically professional communication. Methods: Through relied on the modern communication technique and information technique to construct remote medical information service network platform that based on Internet of Things, and to link medical organization and patients of different regions so as to carry out relevant telemedicine activity. Results: Based on the remote medical information service platform, the project has realized the remote medical information system of high definition video conferencing. And its effect could really and naturally presented clearly and dynamically medical data. Therefore, it could quickly and efficiently enhanced the quality and effect of remote medical treatment, teaching and academic conferences. Conclusion: Telemedicine can overcome obstacles leaded by time and space in getting medical service, and telemedicine information service platform is a efficient way in modulating unbalance of medical resource distribution, expediting the construction of primary medical service system, promoting equalization of urban and rural medical service and alleviating problems when people get medical service.
RESUMO
Prostate cancer is one of the most common malignant tumors in the male urinary system as well as the second leading cause of cancer death in men. Prostate specific antigen (PSA) screening is the main method for the early diagnosis of prostate cancer, but has a low specificity for its detection. In recent years, a variety of tumor markers with high sensitivity and specificity have been found. This review focuses on some of the more promising tumor biomarkers such as prostate cancer antigen 3, early prostate cancer antigen, prostate-specific membrane antigen, alpha-methylacyl-CoA racemase, and vascular endothelial growth factor.

<p><b>OBJECTIVE</b>To study the inhibition effect of grape procyanidin (GPC) on the cell apoptosis and injury of proliferation induced by radiation.</p><p><b>METHODS</b>Three indices including apoptosis rate, proliferation rate and expression of bcl-2 and bax protein were examined in the mice pancreas after taking different dose GPC by mouth and radiation by (60)Co-gamma ray once.</p><p><b>RESULTS</b>The cell proliferation and bcl-2 expression in high dose GPC group (3.16% +/- 0.13% and 49.8% respectively), were higher than those in radiation control group (0.64% +/- 0.11%, 29.7%), but the cell apoptosis rate and bax expression (19.8% and 55.0% respectively), were lower than those in radiation control group (35.6%, 85.7%). All the above differences were statistically significant (P < 0.05).</p><p><b>CONCLUSION</b>GPC has certain protective effect against the mice pancreatic cell apoptosis and the abnormal expression of bcl-2 and bax protein induced by (60)Co-gamma.</p>
