BACKGROUND: Previous research reveals that, the morphous, structure, physicochemical property and mechanical characteristics of matrix in buffalo cornu all contribute to the biomaterials in the field of orthopaedics.OBJECTIVE: To investigate the correlation between the duration of matrix in buffalo cornu soaked in 30% hydrogen peroxide and the antigenicity, the biomechanical intensity of matrix in buffalo cornu treated by deproteinization.DESIGN, TIME AND SETTING: Measurement experiments were performed in the Mechanics Laboratory, Kunming University of Science and Technology (Kunming, Yunnan, China) from February to March in 2000.MATERIALS: Buffalo was provided by Luxi Abattoir of Yunnan Province (China), and then processed into test pieces at a nominal thickness.METHODS: The metric test pieces were rinsed with distilled water and soaked by chloroform-methyl alcohol at a ratio of 1:1 for 48 hours, then in 30% hydrogen peroxide for 24 and 48 hours, which served as the experimental group. While those remaining untreated were taken as controls.MAIN OUTCOME MEASURES: The modulus of elasticity and compressive strength were measured by electric measurement method and direct pressurization method, respectively.RESULTS: The modulus of elasticity between the experimental group and the control group had no significant difference (P>0.05). The compressive strength in the control group was significantly higher than that in the experimental group (P<0.01), and there were no significant differences between the experimental group treated for 24 hours and the experimental group treated for 48 hours (P>0.05).CONCLUSION: Subsequent to soaking in 30% hydrogen peroxide for 48 hours, the matrix in buffalo cornu maintains better biomechanicai intensity.

This review focuses on the current situation of traditional Chinese medicine culture propaganda in the field of basic public health and summarizes that traditional Chinese medicine culture propaganda in this field adopts health lectures, household surveys, books, videos, billboards, village radio and other forms. The existing single forms of publicity lead to poor awareness of traditional Chinese medicine knowledge and nonsufficient service in the treatment with traditional Chinese medicine. It is suggested to build and improve the health publicity system, mobilize the residents' senses in an all-round way, and promote nationwide body health.

Objective To investigate the effects of electro-acupuncture (EA) on remyelination after sciatic nerve was transected in rats, so as to explore the possible mechanism of EA in treatment of peripheral nerve injury. Methods After transection of rat's sciatic nerve, the nerve regeneration chamber was built,then the rats were given EA stimulation at frequencies of 5 Hz and 100 Hz, respectively, and Solochrome Cyanine staining, HE staining of nerve fibers, immunohistochemical staining and semi-quantitative image analysis technique were employed to observe the remyelination of the nerve fibers and S-100 protein expression of Schwann cells. Results EA could significantly promote remyelination of the nerve fibers, elevate S-100 protein expression of Schwann Cells in repairing process of transected sciatic nerve of rats. The therapeutic effect of 5 Hz EA group was better than that of 100 Hz EA group. Conclusion EA is an effective way for the treatment of peripheral nerve injury. It can promote proliferation of Schwann cells and nerve fiber myelination. The therapeutic effects of EA are frequency-depondent.

AIM　To build a model of two series of PPARγ agonists thiazolidinedione and aryketo-acid derivatives using 3D-QSAR method, and to reveal the structural features affecting the binding activity to PPARγ, which relates to antihyperglycemic and antihyperlipidemic activity and has a potential application to the treatment of type II diabetes. METHODS and RESULTS　48 agonists with selective activity for PPARγ were analyzed using CoMFA. Based upon the active conformation of rosiglitazone (BRL) extracted from its complex with PPARγ all agonists were aligned. The model from CoMFA showed a high ability to explain and predict the activity of PPARγ agonists with cross-validation correlation coefficient R2=0.656, that of non-cross-validataion R2=0.982, F10，37=201.1, and SE=0.115. CONCLUSION　The CoMFA contour map indicates that the steric fields mainly contribute to the binding effect, and especially a bulky group in the arylketo-acid series favors in the increase of affinity for PPARγ, as compared to the thiazolidinedione.

Objective To approach the characteristics of low-field MRI in early stage of cerebral hemorrhage.Methods 38 cases with early stage of cerebral hemorrhage (superacute stage in 26 and acute stage in 12) underwent low-field MRI examination.Results The hematomas located in the basal ganglia regions in 23,thalamus in 9 and other intracerebral regions in 6.The hematomas appeared as reniform,suborbicular or irregular shape with different size.The hematomas exhibited homogeneously iso-intensity on T_1WI and iso-,slightly high or high signal intensity on T_2WI and FLAIR,in which 5 hematomas exhibited iso- or slightly high signal intensity on T_2WI,and 4 hematomas exhibited homogeneously or inhomogeneously high signal intensity on DWI.There was brain edema around the hematomas.25 hematomas had occupied effect,and 4 hemotomas broke into ventriculus and 2 hemotomas caused by hemorrhage of broken arteriovenous malformation.Conclusion Low-field MRI is of high sensitivity and specificity in diagnosis of early stage of cerebral hemorrhage.

Objective To explore the applied value of MRI in diagnosing pyogenic of infection of gluteus muscles.Methods MRI data in 9 cases with pyogenic infection of gluteus muscles proved by operation or biopsy were retrospectively analysed by comparison with the pathological diagnosis.Results The pyogenic infections localized at unilateral gluteus muscles involving single,two or three gluteus muscles in all cases.On MRI,the infective gluteus muscles were swelling diffusely and the infections developed along the long axis of the muscles and most or all gluteus muscles were involved.4 cases appeared as suppurative myositis and 5 cases developed typical abscess.4 cases were accompanied with subcutaneous edema and the abscess broken into skin in one case.Conclusion The pathological characteristics of the stage and extent of the pyogenic infection in gluteus muscles can be displayed by MR imaging.
