Objective:To determine the three-dimensional stability of atlantoaxial reconstruction with anterior approach screw fixation through C2 vertebral body to C1 lateral mass and Gallie’s technique for C1~2 instability.Methods:25 human cadaveric specimens were randomly divided into 5 groups.The three-dimensional range of motion C1 relatively C2 was measured under five different conditions,the intact state(intact group),odontoid tape Ⅱ fracture(group OTF),fixation with posterior C1~2 transar- ticular screw(group PTS),anterior approach screw fixation through C2 vertebral body to C1 lateral mass(group ASM),ASM and Gallie’s technique(group ASMG). The obtained data were statistically analyzed. Results:The range of motion in all directions group ASMG,ASM and PTS was significantly decreased.There was significant difference among group ASMG,ASM and PTS in flexion/extension and lateral bendings by statistical analysis(P0.05). Conclusion:In vivo biomechanics studies showed that ASMG had unique superiority in the reconstruction of the atlantoaxial stability,especially in controlling the instability of flexion/extension and lateral bendings.It was one kind of reli- able surgical choice for the treatment of the obsolete insta- bility or dislocation of C1~2 joint.

In this paper, we describe mismatch, chaos, and disorder behavior during healthcare seeking. Such structural imbalances, scarcity and surplus make healthcare services less efficient. We give reasons for such phenomena in terms of long-term effects of health resource allocation policy-making and implementation, inherent de-fects within healthcare insurance, incomplete market development, and cultural issues. We then propose four policy strategies, including rational price mechanism, strict referral healthcare system, confidence in basic healthcare facili-ties, and proper healthcare cultures. These will restore orderly healthcare behavior and help realize expectations for the current healthcare reform in China.

Objective To seek a operation method of quality control of biochemical tests in peacekeeping mission via perspective of evidence-based laboratory medicine .Methods Literatures related to quality control of biochemical tests in international peace-keeping were referred ,compared and discriminated .Combined with 5-year peacekeeping laboratory experience ,a set of feasible ap-proaches were worked out and a practice evaluation was performed in a task period .Results Under the supervision of the quality control system ,providing accurate and reliable test results to the clinical ,developing and implementing quality control of biochemical tests were economical ,practical and reliable ,and could guarantee the effectiveness of reports of biochemical test in peacekeeping medical institutions .Conclusion Evidence-based laboratory medicine is important for quality control of biochemical tests in peace-keeping medical institutions .

Hospital Administrative Moral Standard has effects of guide, encouragement, harmonization and rectification. Administration should reflect principles of respect, justice and benefit. It should connect unith the purpose and the way of setting up the hospital, with the aim of educating health staff. The institution of the standard should combine administrative power with its function. The nucleus is to rectify opinion, action, discipline and attitude of the health staff.

Healing garden, as an auxiliary medical technology for autism, presents the characteristics of integrity, controllability, compatibility and nature, which make up for the inadequacy of the current indoor intervention therapy. By way of natural benefit, active support,environmental integration and integrated therapy, it completes stage progressive system intervention and promotes sustainable development in body and mind.

BACKGROUND: Senile hip fracture is a common disease, and its high disability and lethality severely affect the lifetime and quality of life of the elderly.OBJECTIVE: To summarize the research progress of senile osteoporotic hip fractures.METHODS: A computer-based search of CNKI, CqVip, WanFang and PubMed databases was performed for relevant basic research published from January 1995 to September 2016 using the keywords of osteoporosis,hip fracture, epidemiology in Chinese and English, respectively. Meanwhile, references in the searched articles were retrieved, finally 27 eligible articles were enrolled for analysis.RESULTS AND CONCLUSION: (1) The occurrence of senile osteoporotic hip fractures is closely related to the bone mineral density, proximal femur geometry, and fall-strain. (2) The preventions of osteoporotic fractures include primary prevention aiming at risk factors for osteoporosis and secondary prevention for osteoporotic patients. (3) The surgical treatment of femoral neck fracture is divided into open/closed reduction and internal fixation, femoral head arthroplasty and total hip arthroplasty. (4) Sliding hip screw fixation, proximal femoral intramedullary nail, external fixator and femoral head arthroplasty are used to treat intertrochanteric fracture. (5) There are various drugs used for hip fracture, such as calcium, vitamin D, estrogens, calcitonin and bisphosphonates. Indeed, individual treatment contributes to postoperative rehabilitation.
