BACKGROUND:Ibandronate is the typical representative of bisphosphonates drugs,which prevent bone absorption. OBJECTIVE:To verify the effect of Ibandronate on fracture healing after local application. DESIGN,TIME AND SETTING:A randomized control experiment was accomplished in the Medicine Center Laboratory of Southeast University in October,2008. MATERIALS:Thirty-six healthy New Zealand rabbits,aged 6-8 month,weighting 2.1-2.6 kg. Ibandronate injection(1 mL:1 mg) was supplied by Biomedical Engineering Centre of Hebei Medical University. METHODS:Thirty-six healthy New Zealand rabbits were randomly divided into the control,systemic application and the local application groups,with 12 rabbits in each group. All the rabbits were prepared fracture healing models. Rabbits in control group were given no more treatment after model preparation. Animals in the systemic application control group was given 0.1 mg Ibandronate injection through vein or locally. The state of fracture healing were examined and then scored by X-ray at week 2,4,6 and 8 after model preparation. At weeks 1,2,3 and 4,the level of serum tartrate-resistant acid phosphatase 5b(TRAP-5b) were assayed with ELISA. At weeks 2,4,6 and 8,three rabbits were selected from each group randomly and were killed by aeroembolism respectively. Their calluses were intercepted from fracture sites as the research objects. Pathological changes were observed in callus samples and immunohistochemistry stain was performed to examine type I collagen expression in tissues of callus. MAIN OUTCOME MEASURES:①Fracture healing scores. ②The level changes of TRAP. ③The percentage of bone trabecula area. ④Osteoblast index. ⑤Absorbance value. RESULTS:All rabbits were involved in the result analysis. The systemic application group and local application group obtained higher scores than in the control group at weeks 2(P

Objective Non-small-cell lung cancer with ipsilateral mediastinal lymph node metastasis (N2) belongs to heterogeneous subgroup. We analyzed the prognosis of patients with resected N2 NSCLC to determine the clinical significance. Methods The present study comprised 146 consecutive patients whom underwent surgical resection of N2 NSCLC between January 1997 and January 2000. Histological type, location, T primary tumor status, operation mode, clinical N2 (cN2) factor, N2 level(single or multiple), number of positive nodes(N2-num), and the cycles of adjuvant chemotherapy were estimated from the date of operation using the Kaplan-Meier and Log Rank analysis. The Cox regression model evaluated the influence of factors on the survival. Results The 3-and 5-year survival rate of these N2 NSCLC patients were 19.86% and 14.56%, respectively. The patients with tumor in the right lower lobe showed a significantly longer survival than left lobes. The histological type, tumor location, cN2 factor, N2 level and N2-number were associated with survival. A multivariate analysis using Cox regression identified 4 factors of prognosis: tumor site, T status, N2 level and clinical N2 status. Conclusion This article has identified N2 NSCLC subgroups and found that patients with mN2, N2L1 and single N2 have better prognosis.

Nasal supernumerary teeth and additional dental cyst is a common disease in Department of ENT and Department of Stomatology. In reported diseases, patients with a variety of additional teeth appeared in differ ent parts have varied clinical manifestations. Because of no obvious early symptoms, it is more difficult to diagnose, but CT examination in corresponding site can make it easy to diagnose the maxillary sinus and dentigerous cyst diagnosis. Operation is an effective method to cure the disease. Operation is simple, but the defect and tooth cavity after operation is one unavoidable problem for ENT doctor. In relevant literature it can be seen that the disease has a genetic tendency.
