60mg /kg?d ip, of paeonol were given to rats for 15 days. The myocardial ischemia reperfusion injury model was produced by occluding the left coronary artery and releasing the occlusion in rats. This significantly decreased myocardial Ca++-ATPase activitics and CH/PL radical, FFA content, improved mitochondrial membrane fluidity and kept them away from oxygen free radical damage. These results indicated that paeonol has membrane protective effect on myocardial ischemia rcperfusion injury probably by inhibiting the oxygen free radicals and subsequent lipid peroxidation.

OBJECTIVE:To explore the reasons for leg length discrepancy following total hip arthroplasty,and to summarize the prevention and treatment of leg length discrepancy after total hip arthroplasty.DATA SOURCES:A computer-based online search was conducted in PubMed (www.ncbi.nlm.nih.gov/pubmed) for the English articles published between 2001 and 2008 with keywords "Leg length discrepancy,hip arthroplasty" and Wanfang database (http://www.wanfangdata.com.cn) for the Chinese articles published between 2004 and 2009.DATA SELECTION:Totally 154 literatures were retrieved by computer,including 116 English articles and 38 Chinese articles,through reading title and abstract,112 independent and 51 repeated papers were excluded.The remained 29 literatures were performed further analysis.MAIN OUTCOME MEASURES:Reasons for leg length discrepancy and the prevention and treatment of leg length discrepancy following total hip arthroplasty.RESULTS:The main cause of leg length discrepancy after total hip arthroplasty included redundant neck of femur stump,used longer prothesis neck,diminished femur eccentricity,selected longer neck of femur prothesis,as well as larger movement of cotyloid cavity rotation center.The effective approaches of leg length discrepancy after total hip arthroplasty included careful preoperative planning,intraoperative measurement digital templating and image-guided surgery.It could be the adjusted with heel and shaped bottom for the limbs length which was more than 15 mm after operation,and revision operation maybe applied to patients who had more than 20 mm limbs length or combined with complications.CONCLUSIONS:Leg length discrepancy is one of the common complications following total hip arthroplasty.Along with the development of science and technology,to design individual prothesis and computer-assisted navigation joint can be recover farthest joint function.

Objective:To study the histogenesis and cell differentiation of desmoplastic ameloblastoma.Methods:The expression of various protein filaments was detected by immunohistochemical stainning in 20 cases of desmoplastic ameloblastoma and the ultrastructure of the tumor was observed in 4 cases.Results:CKH,CK8 and CK19 were positive in spindle-shaped and polygonal epithlium tumor cells.Vimentin was positive in mesenchymal fibrocytes and smooth muscle actin in some mesenchymal cells.Ultrastructural observation found that tonifilaments were in epithelial cells and there were desmosomes between these cells.In stroma myofibroblasts were presented.Loose connective tissue could be seen around some epithelial cell nests.Conclusion:Desmoplastic ameloblastoma may be arise from the early stage of the dental germ formation, epithelial cells of the tumor had the tendency to differentiate to the keratinized cells.

AimTo observe the effect of infiltration of Methylprednisolone on injured spinal nerve root and the protective function of Methylprednisolone to non-impressed spinal nerve root lesion. Methods The spinal nerve roots were injured in 20 rabbits. Three days later local Methylprednisolone infiltration of spinal nerve root profromed in rabbits in experiment group, while rabbits in the control roup received equal amount of 0.9% natriichloridi instead. The conduct velocity of spinal nerve root was measured one week after operation. The histological change of spinal nerve root and immunohistochemical stain of posterior horn of spine were observed by microscope. Results The conduct velocity was recovered obviously in experiment group. In observation of spinal nerve we found the edema and hyperaemia of matrix were impaired obviously, the lesion focus was minimized, the amount of inflammatory cells was decreased. The area of substance P positive fiber and its terminus in posterior of spinal was smaller in experiment group remarkably than in control group. ConclusionsThe local infiltration of Methylprednisolone can relieve inflammation, inhibit the transmission of pain and accelerate recovery of spinal nerve root.
