Objective To investigate the effect and safety of proximal femur locking compression plate for treatment of intertrochanteric fracture in old patients. Methods Clinical data and visit records of 98 cases of intertrochanteric fracture old patients were analysed retro-spectively. According to the treatment of operative methods, these patients were divided into two groups: 46 patients in the control group were given the dynamic hip screw fixation; the other 52 cases in the observation group were given the proximal femur locking compression plate . Compared the therapeutic effect and safety of the two groups. Results The short-term and long-term therapeutic effect of observation group were significantly better than the control group,and the safety of observation group was higher than that of the control group,the differ-ences were statistically significant (P<0. 05). Conclusion Proximal femur locking compression plates is an effective surgical treatment for old patients with intertrochanteric fracture. It can significantly improve the function of hip joint and reduce the risk of postoperative complica-tions. As it is of significant effect and high safety, it is worthy of clinical popularization.

Objective To study the application value of cytological examination and biopsy for the transbronchial needle aspiration (TBNA) in the diagnosis of cancer. Methods 101 patients with lung disease by CT that need TBNA examination to make final diagnosis were selected. They were executed with routine ex-amination of TBNA. And then pathologic biopsy and cytological examination were applied on the collection sam-pies. Results 86 patients among the 96 subjects were finally diagnosed by TBNA. So the ratio of final diagno-sis was 94. 5%. And the positive ratios about transbronchial needle aspiration and ring clamp biopsy, also brush biopsy, were 71.4% 、75.8%、 61.5%. Only 5 patients were histodiagnosed by just transbrenchial needle aspiration. Conclusion TBNA plays an important role on the diagnosis of lung tumor with different types. And the combination of three methods can improve the diagnosis pro-gressively.

BACKGROUND:Occlusal stimulation is essential for mandible function and remodeling, but there is stil a lack of clear understanding about the effect of occlusal stimulation on the bone remodeling in the process of bone defect repair using bone grafts. OBJECTIVE:To analyze the possible regulative effect of occlusal stimulation on bone remodeling in the process of bone defect repair using colagen substitutes. METHODS:Standard models of bone defects were respectively established in left mandible and parietal bone area of adult Sprague-Dawley rats. Then the bone defects area were filed with colagen and bone meal. The differences of two bone defects areas were observed by X-ray, hematoxylin-eosin staining, Gomori staining, tartrate-resistant acid phosphatase staining and bone morphogenetic protein 2 immunohistochemical staining at the 12th week after operation. RESULTS AND CONCLUSION: New bone formation was visible in the bone defect regions of the mandible and parietal bone. The amount of lamelar bone formation and the degree of mineralization of the new bone were significantly increased in the parietal bone defect compared with the mandibular bone defect area, indicating the bone remodeling in the parietal bone defect area was better than that in the mandible bone defect area. The integral absorbance values of tartrate-resistant acid phosphatase and bone morphogenetic protein 2 in the parietal bone defect area were lower than those in the mandibular bone defect area, indicating that the viabilities of osteoblasts and osteoclasts in the parietal bone defect area were lower than those in the mandible bone defect area. These results demonstrate that occlusal stimulation may delay the bone remodeling during the repair of mandibular bone defects by regulating bone mineralization and maturation.

BACKGROUND: Consummate innervation plays an important role in bone formation. Nerve injury can impact normal bone metabolism, whereas bone regeneration depends on nerve regeneration in the innervation site to some degrees. Modified implant surface structure or usage of growth factors in local region can promote osseointegretion.OBJECTIVE: To retrospectively analyze effects of nervous system dominance bone metabolism and denervation on bone remodeling, innervated establishment and osseoperception during osseointegration following implantation.METHODS: The first author retrieved Pubmed database (http://www.ncbi.nlm.nih.gov/PubMed) and Wanfang database (http://www.wanfangdata.com.cn) (1990/2008) for publications of effects of nervous system dominance bone metabolism and denervation on bone remodeling, innervated establishment and osseoperception during osseointegration following implantation,with the key words of "bone metabolism, innervation, osseointegrationosseoperception" . Articles of repetitive contents were excluded. A total of 54 literatures were primarily obtained. According to inclusion criteria, 28 literatures were selected for summary.RESULTS AND CONCLUSION: Signals derived from the nervous system exert potent effects on osteoclast and osteoblast function. A ubiquitous innervation of all periosteal surfaces exists and its disruption affects bone remodeling. Several neuropeptides, neurohormones, nerotransmitters and their receptors are detectable in bone, and make it clear that nervous system is involved in bone metabolism and regeneration. Establishment of innervation of soft and hard tissue around implants may play an important role in osseointegration and osseoperception. Further studies will be required to explore the basic of anatomy,neurophysiology and neuropathology, which forms osseoperception.
