Objective To investigate the the effect and interaction of morphine dependence model and naloxone doses on withdrawal intensity. Methods To observe the withdrawal signs and weight loss in two kinds of morphine dependent rats after the precipitating by naloxone of different doses an devaluate the withdrawal intensity.Results Morphine dependence were successfully induced in two ways.There was no significant difference of withdrawal intensity in five-day model(total morphine dose 380mg.kg－1) after precipitating by naloxone of 2mg.kg－1 and 4mg.kg－1（P＞0.05）. Withdrawal intensity of twelve-day model(total morphine dose 1365mg.kg－1)increased significantly with the increase of naloxone dose（P＜0.01）,but it was more intensive significantly than five-day model only after 4mg.kg－1 dose of naloxone. Conclusion Appropriate method should be used to induce morphine dependence and these experimental factors should be combined in assessment of withdrawal intensity.

Objective To explore the role of astrocytes transient receptor potential channel 6(TRPC6) in rat brain injury (TBI).Methods Thirty-nine male Sprague-Dawley(SD) rats were divided into the sham operation group,injury group and deferoxamine(DFX) group(n=13).According to the previous model construction scheme established by our research group Feeney method,the rat brain impact injury model was established.The Morris water maze test was performed and the defected brain volume was measured.The immunofluorescence was adopted to detect the co-expression of TRPC6 and GFAP.Then Western blot was performed.Results The defected brain volume after TBI in the DFX group was significantly decreased compared with the injury group [(115.35 ± 13.70)mm3 vs.(209.99 ± 16.70)mm3]] (P＜0.05).The Morris water maze test found that the platform search strategy and search time in the DFX group were(3.13 ± 0.35) and(36.15 ± 26.63)s,which were significantly improve d compared with (2.13±0.64) and(110±47.34)s in the injury group(P＜0.05).The immunofluorescence found that GFAP in the DFX group was highly expressed,moreover the co-expression with TRPC6 was increased.Western blot found that TRPC6 in the DFX group was significantly down-regulated(P＜0.01).Conclusion In rat TBI early stage,strocytes are activated after DFX treatment and TRPC6 is highly expressed,playing a neuroprotective role.

BACKGROUND:The finite element model has been developed from two-dimensional model to three-dimensional model, from linear model to nonlinear model. As the advantage of this method in the analysis of mechanical characteristics of the irregular objects, the finite element model has been widely used in the research of orthopedic biomechanics, especial y in the research of hip joint. OBJECTIVE:To analyze the stress state of human femur with finite element analysis method and to investigate a method that can rapidly construct femoral finite element model and precisely analyze the biomechanics. METHODS:Normal male femur was used as specimen for CT scan to obtain cross-sectional images of femur in each slice. Three-dimensional reconstruction was performed with DICOM data and MIMICS software, then the femoral three-dimensional finite element model was established with the finite element analysis ABQUS 6.8 software, and the stress distribution of the model was analyzed under loading condition. RESULTS AND CONCLUSION:Based on DICOM data, three-dimensional finite element model of femur was constructed more quickly and precisely. The models were divided into 38 636 nodes and 201 422 units. The model included the parts of cortical and cancel ous bone. The biomechanical test results were accorded with the previous results, so the model could objectively reflect the real femur shape and biomechanical behavior with high precision. The Mimics software provided a simpler and effective method for the construction of femur model and improved the efficiency of modeling, and the three-dimensional finite element model based on DICOM data was accurate in shape and can be used for the normal research on biomechanical behavior of femur. The stress distribution analyzed with ABQUS 6.8 software is consistent with the clinical observation.
