Because of the factors such as degeneration or congenital dysplasia which leads to medial tibiofemoral compartment tightness, the arthroscopic surgery of this part might have limited vision and narrow operating space, which causes missed diagnosis and iatrogenic injury.Medial collateral ligament ( MCL) release technique is a simple, effective and safe procedure.By releasing part of the ligament fiber, this operation can effectively expand the visual field and operation space.avoiding the risk of iatrogenic injury of cartilage and missed diagnosis.MCL release technique is an effective method to solve the arthroscopic examination and endoscopic operation for medial compartment tightness of the knee joint.This article reviewed the technique of MCL release.

Objective To observe the effects of termination of pregnancy with Guizlfi Fuling Capsule plus Mifepristone.Methods 75 early pregnant women were randomly recruited into a treatment group and a control group.Women in the control group were applied with Mifepristone plus Misoprostoi.Form the 3rd day,women in the treatmcnt group were applied wilh Guizhi Fuling Capsule(3 times daily,and 3 granules for each time)for successive 7 days oil the basis of medicines used in the control group.Compared and analyzed the therapeutic effects of both groups.Results The average time for ovum evacuation in the control group and the tretment group was(6±1.8)h and(3±2.6)h separately.Besides both bleeding volume and bleeding time in the Izeatment group were lower than the eonlxol group.Conelusion Guizhi Fuling Capsule plus Mifeoristolle therapy will shorten ovum evacuation time and decrease bleeding volume.

Ultrasound diffraction tomography (UDT) possesses the characteristics of high resolution, sensitive to dense tissue, and has high application value in clinics. To suppress the artifact and improve the quality of reconstructed image, classical interpolation method needs to be improved by increasing the number of projections and channels, which will increase the scanning time and the complexity of the imaging system. In this study, we tried to accurately reconstruct the object from limited projection based on compressed sensing. Firstly, we illuminated the object from random angles with limited number of projections. Then we obtained spatial frequency samples through Fourier diffraction theory. Secondly, we formulated the inverse problem of UDT by exploring the sparsity of the object. Thirdly, we solved the inverse problem by conjugate gradient method to reconstruct the object. We accurately reconstructed the object using the proposed method. Not only can the proposed method save scanning time to reduce the distortion by respiratory movement, but also can reduce cost and complexity of the system. Compared to the interpolation method, our method can reduce the reconstruction error and improve the structural similarity.

0.05). Conclusion:The rapid tooth movement is achieved impressively through dentoalveolar distraction osteogenesis, and tooth inclinations become largely associated with tooth movement.

Objective:To identify the expression of plasmid pLNCX-EGFP-C1-hri targeting the gene of Human ribonuclease inhibitor (hri) in PA317 cells which is capable of expression in mammalian cells.Methods: The vector of pLNCX-EGFP-C1-hri was transfected into PA317 cells by Lipofectamine 2000 and then the expression of recombinated plasmid was verified in living cells by observing the transcription level of egfp-hri fusion gene mRNA with RT-PCR method and the expression level of egfp-fusion hRI protein with western blotting method respectively.Results: Both RT-PCR and western blotting showed the egfp-hri fusion gene was obviously expression in PA317 cells.Conclusion: The plasmid of pLNCX-EGFP-C1-hri targeting hRI is successfully constructed and the protein of hRI can be expressed in PA317 cells correctly.

Objective To study the effects of hypoxic preconditioning on the Fos and Jun expression and apoptosis in cultured rat hippocampal neurons after anoxia\|reoxygenation. Methods The hippocampal neurons cultured for 12d from control and hypoxic\|preconditioning groups were exposed to anoxia environment (0\^90?l/L N\-2+0\^10?l/L CO\-2) for 4h and than reoxygenated for 24h and 72h.The expression of Fos and Jun were revealed immunocytochemically using the antiserum against Fos and Jun.The apoptosis was examied using the terminal deoxynucleotidyl transferese\|mediated biotinylated deoxyuridine triphosphate nickel and labeling(TUNEL) method and flow cytometric analysis. Results The increased of percentage of Fos and Jun positive neurons and apoptosis neurons in cultured hippocampal neurons after anoxia\|reoxygenation than those in befor anoxia.The precentage of Fos and Jun positive neurons and apoptosis neurons were less in the hypoxic\|preconditioning group than that in control aftre anoxia\|reoxygenation.Conclusion\ Hypoxic\|preconditioning increases tolerance of hippocampal neurons to anoxia and decreases the precentage in Fos and Jun expressing neurons and apoptosis neurons in hippocampus aftre anoxia\|reoxygenation in vitro. \;[
