ObjectiveTo explore the effect of selective exercise training technique combined with ultrasound therapy on patellofemoral pain syndrome. MethodsPatients who met the research criteria were assigned into treatment group and control group randomly between July 2011 and August 2012. Each group had 28 patients. There were no significant differences in gender, age and body mass index between the two groups (P>0.05). Patients in the treatment group received selective exercise therapy and ultrasound therapy, while patients in the control group received normal exercise treatment and ultrasound therapy. Knee numerical pain rating scale (NPRS) and knee functional obstruction assessment were performed on all the patients before treatment and 5 days after treatment (on the 6th day) for comparison. ResultsBefore treatment, the score of NPRS in the treatment group and the control group was 4.7±0.8 and 4.8±0.9, respectively, with no significant difference (P>0.05). The score of functional obstruction assessment was 11.2±2.2 and 12.2±2.7 in the two groups without significant difference (P>0.05). Five days after treatment, the NPRS score decreased to 2.1±0.5 in the treatment group and 4.2±1.0 in the control group, and the knee functional obstruction assessment score decreased to 6.4±1.9 and 11.1±2.6, respectively. Both groups improved significantly in NPRS score and knee functional obstruction assessment score (P＜0.05), while the treatment group exhibited more improvement in the two scores than the control group (P＜0.05). ConclusionSelective exercise training is effective for improving the pain and function of patients with patellofemoral syndrome.
ObjectiveTo explore the effects of pilose antler blood wine on bone mineral density and T-lymphocyte subsets of ovariectomized female Sprague Dawley (SD) rats. MethodsSixty female SD rats were randomly divided into six groups:normal control group, osteoporosis model group, pure ethylalcohol group, high dose of pilose antler blood wine group, medium dose of pilose antler blood wine group and low dose of pilose antler blood wine group. Normal control group and osteoporosis model group were given saline with the dose of 9.1 g/(kg·d). Pure ethylalcohol group was given pure ethylalcohol with the dose of 9.1 g/(kg·d). The doses of pilose antler blood wine were 4.5, 9.1 and 13.6 g/(kg·d) respectively in low, medium and high dose of pilose antler blood wine group. After the feeding of pilose antler blood wine for 30 days, the bone mineral density and T-lymphocyte subsets of rats were assessed. ResultsThe difference in bone mineral density among the three pilose antler blood wine groups was significant (P<0.05); the most obvious improvement of one mineral density was found in low and medium dose of pilose antler blood wine groups (P<0.05). The CD4+ T cells and CD4+/CD8+ significantly increased and CD8+ T cells proportion decreased significantly in pilose antler blood wine group compared with those in the osteoporosis model group (P<0.05). CD4+ T cells in medium dose group increased obviously compared with that in the high dose group (P<0.05). CD4+/CD8+ in low and medium dose groups obviously increased compared with that in high dose group (P<0.05). CD4+ T cells of medium dose group obviously increased compared with that in pure ethylalcohol group (P<0.05). CD8+ T cells in medium and low dose groups obviously decreased compared that in pure ethylalcohol group (P<0.05). CD4+/CD8+ in the three dose groups increased significantly compared with that in pure ethylalcohol group (P<0.05). ConclusionTree different doses of pilose antler blood wine could prevent the osteoporosis and improve the immune function. The effects of medium and low dose of groups were more obvious.
