Objective:To explore the clinical results of the operation of posterior decompression,vertebral interbody fusion with cage and transpedicular screw fixation for the treatment of recurrent lumbar disc herniation.Methods:51 cases treated with the operation of posterior decompression,vertebral interbody fusion with cage and transpedicular screw fixation were reviewed retrospectively.The results were evaluated with Japanese Orthopedic Association score.Results:The average operative time was 160 minutes and the average blood volumn was 580 ml.51 cases were followed for an averge period of 3 years.There was a significant increase of JOA score in the latest follow-up(P

In medical work, we usually consider patients as our "God", but our "God" who actually don't know their rights of being patients. think doctors to be "the God", "The Saviour". Many of our medical staff are not realizing patiends' rights and that patients' alternatires of doctors is the core of retaining the relationship between patients and medical personnel. In the essay through establishing patients' rights, medical personnel will be restricted to their occupational morals.

0.05).Conclusion The gene polymorphism of MMP-9/C1562T may be unrelated with IS.

0 05), and the adverse reaction for sulthiame was mild and no necessary to cure.Conclusion It is effective and safe in the treatment for GTCS with sulthiame.

Objective To observe the neuroprotective effect of Gangliosides on rats with cerebral ischemia-reperfusion. Methods Rat models were established through middle cerebral artery occlusion and divided into sham-operation group, ischemia-reperfusion group and Gangliosides group. The volume of infarotion and changes of NAA and Lactate at different time point were evaluated by DWI and MRS examinations. Results The mean infarcted volume measured by DWI at 1 h, 3 h and 6 h after ischemia-reperfusion in Gangliosides group was (30.32?8.18) mm3, (35.17?12.45) mm3 and (31.4?8.56) mm3, respectively, versus (204.6?37.77) mm3, (218.9?67.33) mm3 and (213.4?99. 95) mm3 in ischemia-reperfusion group.There were significant differences between the two groups (allP

Objective A method for the determination of 4-methylimidazole in soy sauce by capillary gas chromatography was studies.Methods The method consisted of a methylene chloride to elution,followed by concentration of the eluate.N,N-Dimethylaniline(IS) was added in and GC analysis of the eluate,prior to GC analysis.The GC analysis was carried out by DB-FFAP capillary column and nitrogen phosphorus detector(NPD).Results The linear range was 4.9mg~1.5?102 mg/L and the limit of detection was 0.16 ug/L.The average recoveries were 97.25%and 99.44% by stand addition method in 0.0102mg and 0.0602mg 4-methylimidazole.Conclusion The method was simple,rapid and sensitive.A useful method for determining 4-methylimidazole in soy sauce was provided for forensic analysis.

Nano-hydroxyapatite has been widely used as reconstructive and prosthetic material for osseous tissue,owing to its excellent biocompatibility and tissue bioactivity.But the poor mechanical property of hydroxyapatite restricts its further application.In order to enhance the comprehensive performance of the material,many researches have been dedicated to the synthesization of the composite materials.This article reviews the main preparation methods of nano-hydroxyapatite and the advancement in research of its composite.The directions in this research area are described as well.

Acupuncture for stroke rehabilitation is of multi-targets, the treatments of which are not only for hemiplegia, but also cover a wide variety of aspects, such as aphasia, dysphagia, dysarthria, cognitive disorders, bowel or bladder dysfunction, ataxia and post hemiple-gic pain, etc. Based on the experiences of stroke rehabilitation with Integrated Traditional Chinese and Western Medicine over 20 years, this paper discussed the selection of acupoints, needling manipulations, opportunity of intervention, quantity of stimulations, the needle-retaining time as well as the impact on spasticity after hemiplegia referring to ancient and modern literatures and modern rehabilitation theory.

Purpose To prepare streptavidin-tagged mouse interleukin-4(mIL-4-SA)bifunctional fusion protein and to study on its bioactivity.Methods The mIL-4 gene was cloned by RT-PCR and cloned into pET21 vector to get mIL-4-SA-pET21 expression plasmid.The mIL-4-SA fusion protein was expressed in BL21 (DE3)host bacteria and purified through the Ni-NTA affinity chromatography and refolded by dilution and dialysis.The effect of mIL-4-SA fusion protein on mouse thymocytes proliferation was evaluated by MTY.Flow cytometric analysis was performed to detect the mIL-4-SA fusion protein on the biotinylated B16F10 tumor cells.Results The mIL-4-SA-pET21 vector was successful by constructed and the mIL-4-SA fusion protein was expressed in BL21(DE3)at about 35%of total bacterial proteins.The purity of mIL-4-SA Was about 95% through Ni-NTA.The mIL-4-SA fusion protein exhibited bifunctional activities,i.e.,stimulative effect for mouse thymocyte proliferation and SA-mediated high-affinity binding to biotinylated cell surfaces(anchoring modified rate Was about 96.69%).Conclusion The mIL-4-SA fusion protein was expected to be developed for the treatment of tumors.

Purpose To prepare bFGF-PLGA microspheres and to investigate the characteristics. Methods The bFGF-PLGA microspheres were prepared by W_1/O/W_2 multiple emulsion volatilizing method, the morphology was investigated using scanning electron microscope (SEM), the ELISA method was used to establish the regression equation and to detect the drug loading amount and encapsulation efficiency, as well as sustained-release profile in vitro . Results The microspheres seemed to be smooth and uniform with mean particle size of (0.75 ±0.08) μm,the the drug loading amount and encapsulation efficiency were [(59.9± 1.9) × 10~(-3)] % and (79.9±2.8)%, respectively, the accumulative release ratio was up to 80 % in the continuous period of forty-five days. Conclusion The bFGF-PLGA microspheres have better pharmaceutical properties and long-time sustained release effect in vitro.
