Objective: To investigate the intervention of Shiquan Dabu Decoction (SQDBD) in the protein expression of VEGF. Methods: 50 C57BL/6 mice inoculated with lewis lung cancer were randomly divided into five groups and treated by different drugs. The ratio of antitumorand and antimetastatic of each group were calculated after 15 days’ treatment. The expression of VEGF was detected by SABC immunohistochemical method. Results: Low, medium and high dosages of SQDBD had the function of antitumor and antimetastusi at different extent. SQDBD could inhibit the positive expression of VEGF protein. Conclusion: Inhibition of the expression of VEGF protein is possibly one of the mechanisms of SQDBD in antitumor.

American medical colleges attach great importance to the humanistic education.The rich humanities curriculum is fully integrated into the teaching practice thus the mutual penetration of medicine and the humanities is achieved.They have specific and detailed examination evaluation system and the teaching method was more practical and participatory.By contrast,nost of the medical colleges in our country neglect the humanities construction and the cultivation of medical students' humanistic spirit.The coverage of the humanities curriculum is relatively narrow and the faculty is insufficient.We should promote the development of humanistic cducation,attach importance to the construction of medical humanities,set up appropriate curriculum system,increase the investment in faculty and reform the teaching method and examination method.

BACKGROUND:The phenomenon of osteoinduction by biomaterials has been proven in animal experiments. OBJECTIVE:To investigate whether the ability of a biomaterial to initiate bone formation in ectopic implantation sites improves the performance of osteoinductive biomaterial as a scaffold for tissue-engineered bone. METHODS:We compared ectopic bone formation by combining autologous adipose-derived stromal cells with an osteoinductive and a nonosteoinductive biphasic calcium phosphate ceramic to create a tissue engineering construction in the muscle of dogs. Al implants were implanted in the back muscle of 10 adult dogs for 8 weeks and 12 weeks, including osteoinductive biphasic calcium phosphate ceramic+adipose-derived stromal cells (osteoinductive complex group), osteoinductive biphasic calcium phosphate ceramic (osteoinductive broup), nonosteoinductive biphasic calcium phosphate ceramic+adipose-derived stromal cells (nonosteoinductive complex group), and nonosteoinductive biphasic calcium phosphate ceramic (nonosteoinductive group). Micro-CT analysis and histomorphometry were performed to evaluate and quantify ectopic bone formation. RESULTS AND CONCLUSION:Ectopic bone formation was visible in the osteoinductive complex group and osteoinductive group, and the former group was superior to the latter one in quality of new bone (P<0.05). However, there was no ectopic bone formation in the other two groups. Micro-CT results were consistent with the histomorphological detection. These findings indicate that osteoinductive biphasic calcium phosphate ceramic, as a kind of bone tissue engineering scaffold material, has a better osteogenic capacity, while adipose-derived mesenchymal stem cells serve as seed cells to promote the ectopic bone formation.

This study aims to investigate the preventive role and potential mechanisms of blocking extracellular HMGB1 function on doxorubicin induced cardiac injury. Mice were treated with HMGB1 blocker glycyrrhizin 1 h before and one time every day (intraperitoneal, 10 mg per mouse) after doxorubicin injection, and sacrificed on the day 14 after doxorubicin challenge. Cardiac function was evaluated by echocardiography and hemodynamic measurement. Myocardial inflammation and collagen deposition were analyzed by immunohistochemistry and picrosirius red staining. The interaction of HMGB1 and TLR2 was assessed by co-immunoprecipitation and confocal microscopy. The protein contents of HMGB1, MyD88, p65NF-kappaB and phospho-p65NF-kappaB were measured by Immunoblot. Compared with mice treated with saline, doxorubicin treatment led to an upregulation in HMGB1 expression. Blocking HMGB1 activity with glycyrrhizin protected mice against cardiac dysfunction, inflammatory response, and cardiac fibrosis induced by doxorubicin challenge. Glycyrrhizin inhibited the interaction of HMGB1 and TLR2, and blocked the downstream signaling of TLR2. In conclusion, blocking HMGB1 protected against doxorubicin induced cardiac injury by inhibiting TLR2 signaling pathway.
