BACKGROUND: Chinese kidney-tonifying herb is commonly used in orthopedics department. However, individual effects of different ingredients remain poorly understood. OBJECTIVE: To observe influence of effective ingredients of Chinese kidney-tonifying drugs on bone healing and hemorheology of rats with bone injury. METHODS: Rat model of fracture of shaft of the femur was established, and treated by intragastric administration separately with extractive rhizoma drynariae total flavonoids, epimedium total flavonoids, dodder total flavonoids, naringin, quercetin and hesperidin. Blood and bone samples were harvested after 21 days to detect the extent of bone healing and hemorheology indexes. RESULTS AND CONCLUSION: The effective constituents of different Chinese kidney-tonifying drugs were beneficial to bone healing, and the effect of rhizoma drynariae total flavonoids and epimedium total flavonoids was better than the other drugs. Rhizoma drynariae total flavonoids and epimedium total flavonoids effectively inhibited blood viscosity under low shear, and reduced erythrocyte aggregation index and the aggregation and adhesion of platelet (P < 0.05), but it had no evident effects on erythrocyte deformation. This shows that the effective ingredient of the Chinese kidney-tonifying drugs can promote bone healing and exert certain effects on hemorheology. In particular, rhizoma drynariae total flavonoids exhibits the best effect.

ObjectiveTo evaluate the role of perfusion weighted magnetic resonance imaging ( PWMRI ) in distinguishing brain glioma recurrence for postoperative radiotherapy patients.Methods Thirty-five patients with suggested recurrent brain glioma (20 true,15 false) were examined by conventional MRI and PWMRI.Regions of interests (ROI) were manually drawn in contrast-enhancing lesion,surround edema region and normal white matter of contra-lateral brain on regional cerebral blood volume (rCBV) images.rCBV values of ROI and rCBVmax were measured,the standardized rCBV ratios were calculated,The mean rCBVmax ratio were compared between two lesion types with group t-test.The rCBVmax ratios of contrastenhancing regions was analyzed by the receiver operating characteristic curve.ResultsThe mean rCBVmax ratio of contrast-enhancing lesion in tumor recurrence was higher than those in non tumor recurrence (4.36vs 1.28,t =3.00,P =0.005 ).The mean rCBVmax of edema regions in tumor recurrence was also higher than those in non tumor recurrence ( 1.79 vs 0.85,t =2.41,P =0.026).Four patients with recurrent tumor and three with non tumor recurrence were wrong diagnosed when set the recurrent tumor rCBVmax ratio ＞2.15.The diagnostic sensitivity,specificity and accuracy for recurrent tumor by PWMRI were 80％respectively.Conclusion PWMRI examination is a useful method for distinguishing brain glioma recurrence.
