Objective To study the MR features and diagnostic value of tethered cord syndrome(TCS).Methods MR findings of 30 cases with TCS were reviewed.All cases were confirmed by operation and pathology.Results In 30 cases,the levels of the tips of the conus were below the middle of L 2 vertebral body.Spinal cords were fixed as result of being drawn.MR findings were as follows:Single thickened and tightened filum terminale(4 cases,13%);Lipoid buld(13 cases,43%);Myeloey stocele(3 cases,10%);Meningcele(4 cases,13%);Tumor in spinalcannal(6 cases,20%) Included neurofibroma (2 cases),dermoid cyst (2 cases) and epidermoid (1 cases),teratoma(1 cases).Conclusion MRI with high soft tissue resolution and mutiple sections imaging is superior to any other imaging means,it can clearly demonstrate the position and shape of the spinal cord conus as well as the associated malformation.

[Objective]To measure the contents of Nutmeg ether,and its regularity varying with decoction time.[Method]RP-HPLC method was used.The chromatographic conditions were listed below Tigerkin-C18 column(150mm?4.6mm.5?m),amobine phase composed of metranol-0.025mol/L phosphoric acid(70∶30),a flow rate of 1mL ?min-1 and wave lengths was 282nm,column temperature was 25 ℃.[Results]In the range of 0.4?g ~2.0?g,the linear was very well between the content of Nutmeg ether and peak area.[Conclusion] The contents of Nutmeg ether in decoction reached the peak at 2.45min after Nutmeg ether was added in boiling water.

Forty-four mice were used in this experiment. The animal model of septic shock was produced by intraabdomcnal injection of the viable B. coli. The animals were divided into 5 groups. During the course of the development of the septic shock.some of the animals were killed and blood from inferior vena cava was withdrawn for the determination of cAMP, cGMP and cortisol. Tissues from both sides of the adrenal glands, lower pole of the left kidney, left ventricle and right lobe of liver were removed for determination of cAMP and cGMP. The results showed that, during the early stagenof septic shock, the levels of cAMP, cGMP and cortisol were raised, followed by steady lowering of these levels as the shock became more profound.Base on the results of this experiment the author pointed out that the large dose glucocor-ticosteroids may be useful during the early stage of septic shock

Hospital information system (HIS) has already become indispensable for modern hospital. Data from it being important for patients and hospitals, their safe storages have been important missions for HIS. The means of storages introduced in detail, two kinds of methods are put forward according to the characteristics of HIS data, which apply SAN and NAS to HIS.

Epigenetics is the study of genomic structural modifications that affects gene expression without DNA sequence change.Epigenetic mechanisms for the regulation of gene expression include DNA methylation,histone modifications,and microRNAs.DNA methylation may contribute to silencing gene expression which is a major mechanism of epigenetic gene regulation.DNA methylation regulatory mechanisms in lens development and pathogenesis of cataract represent exciting areas of research that have opened new avenues for association with aging and environment.This review concludes current understanding of the major mechanisms and function of DNA methylation in lens development,pathogenesis of age-related cataract,secondary cataract and complicated cataract.By understanding the role of DNA methylation in the lens disease and development,it may help to develop a new therapeutic approach to clinical treatment of cataract.

The issue of medical morality got more and more attention in the change of modern china society.It is not just an issue among the medical profession,but also bears the multi-meaning of politics,economics and culture.In the context of cruel environment of modern china society,many problems of medical morality existing among the medical profession were disclosed thoroughly.How to solve these problem concerns the health of public,and the development of china medical.In that time,many china medical professionals managed to put forward strategies to promote the development of china modern medical,which we should use for reference nowadays.

Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint.
