Objective To observe the effect of rapid reduction of physical activity on bone mass (BMC), bone mineral density (BMD)and bone metabolism in growing rats. Methods 48 male SD rats were divided into the high-intensity exercise group (T1, n=12), high tolow-intensity exercise group (T2, n=12), low-intensity exercise group (T3, n=12) and control group (Con, n=12). During the first 6 weeks,the rats in T1 and T2 group ran on treadmill with high intensity, while rats in T3 group took low-intensity treadmill exercise. 6 rats were sacrificedfrom each group at the end of 6th week. BMC, BMD of femur were measured with DEXA. Alkaline phosphatase (ALP), osteocalcin(BGP), tartrate-resistant acid phosphatase (TRACP) were detected with ELISA. The exercise intensity of T2 group was reduced rapidly to alow level as in T3 group, but remained in the other 2 groups. At the end of the second 6 weeks, the other rats were investigated again. ResultsCompared with the first measurements, ALP and BGP of the T2 group decreased significantly (P<0.05), and TRACP increased (P<0.05). There was no significant difference in BMC and BMD of femur (P>0.05). Conclusion Rapid reduction of physical activity can suppressbone formation and stimulate bone resorption of long bone among growing rats.

Objective To observe the effects of pulsed electromagnetic field (PEMFs) or/and exercise on the area bone mineral density (aBMD) and volume bone mineral density (vBMD) of rats with osteoporosis induced by tretinoin gastric perfusion.Methods 100 female SD rats were randomly divided into 5 groups with 20 rats in each group： PEMFs group, exercise group, PEMFs plus exercise group, osteoporosis group and healthy control group. Except for the healthy control group, the osteoporosis models of other 4 groups were built by tretinoin gastric perfusion. After the building of models, each group was intervened with different treatment. In the 4th, 6th and 8th week after treatment, relevant Results of aBMD and vBMD were tested.Results Compared with the osteoporosis group, the BMD of the rats of PEMFs group, exercise group, PEMFs plus exercise group significantly increased significantly ( P＜0.05) in the 6th week, 4th week and 4th week after treatment respectively. In the 6th and 8th week, there was no significant differences among the PEMFs plus exercise group, the exercise group and the PEMFs group ( P>0.05).Conclusion PEMFs can increase the BMD of the rats with osteoporosis as well as exercise. PEMFs takes effect slower than exercise.

Objective To investigate the effect of comprehensive rehabilitation on the stroke.Methods 120 cases of stroke divided into rehabilitation group(60 cases)and control group(60 cases).They were assessed with Fugl-Meyer Assessment(FMA),Modified Barthel Index(MBI),and Satisfaction with Life Scale(SWLS)before and 1 month,3 months and 6 months after treatment respectively.Results The scores of FMA,MBI and SWLS were improved significantly in rehabilitation group,especially in the 1st month,while that of control group presented the tendency of decline.Conclusion Comprehensive rehabilitation is effective on motion function,activity of daily living and quality of life of stroke patients.

Ethics committee in hospitals aims to protect the rights of human subjects and patients,and provide ethical evaluation and justification for guaranteeing the quality of medical research and treatment.Based on experiences in recent years,this paper suggests the following methods in order to manage the activities of ethics committees and push its further development,such as to draft the ethics system,establish the criteria of ethics,implement the process administration and provide ethics training.

Objective To assess examinational methods of Multi-slice CT(MSCT)in diagnosis of palatine lesions. Methods 28 cases were performed MSCT examination with the conventional method,extending -tongue method,colliding-tongue method and pronouncing method. All images were reconstructed by means of multiplana reconstruction (MPR) and CT virtual endoscope (CTVE). Results Correct diagnosis were obtained through the complementarity of the methods. Conclusion Reasonable examination methods of MSCT is apt to display palatine lesions.

Objective To investigate the quality assurance(QA) and quality control(QC)of 16 slices helical CT angiography in the lower limb. Methods 42 cases clinically suspected as the arterial disease of lower limb undergoing MSCTA were analyzed retrospectively. All reconstructed images were reformed by means of MIP, VR, MPR and CTVE. Results 22 patients were diagnosed correctly by using MSCTA. Compared to DSA and/or surgical results. Sensitivity, specificity and accurate rate were all 100%. Conclusion It is important to strengthen the QA and QC of the 16 slices helical CT angiography in the lower limb.

More and more attention has been drawn on nano-materials in the application of molecular imaging and targeted cancer therapy. Quantum dots, due to their rich surface chemical properties and bright stable fluorescence, have been used as a new type of nano-probes and widely used in molecular, cellular and vivo biological imaging. In recent years, many inspiring achievements have been obtained in the study on quantum dots surface modification and biological imaging in cell and animals. In this article, current status and the latest developments of the study and the application are reviewed.
