摘要
背景:超过50%的糖尿病患者伴随骨质疏松。运动是治疗糖尿病的主要方法,其是否也对糖尿病骨质疏松的发生产生影响目前尚不明确。目的:分析不同运动强度与2型糖尿病大鼠模型骨密度变化。方法:将40只大鼠随机等分为模型组和低、中、高强度运动组,所有大鼠均采用一次性腹腔注射链脲佐菌素建立2型糖尿病模型。低、中、高强度运动组分别进行10,20,30 m/min的跑台训练,1 h/d,6 d为一个周期,每周期训练结束后休息1 d,连续运动8个周期。而模型组不进行运动训练。结果与结论:与模型组相比,低、中、高强度运动组大鼠体质量减轻,血糖水平下降,骨钙素、血钙水平以及股骨生物力学指标增加,血磷和碱性磷酸酶降低,且中、高强度运动组大鼠骨密度增加。提示不同运动强度都对2型糖尿病大鼠模型骨密度和骨代谢具有一定的影响。采用运动方法治疗时采取适当的体育运动能提高血清骨钙素含量,改善骨代谢状况,更好的预防糖尿病骨质疏松症,具有较高的临床应用价值。
BACKGROUND： More than 50% of patients with diabetes are accompanied by osteoporosis. Exercise is the main method to treat diabetes, but whether it has an impact on diabetes osteoporosis is unclear. OBJECTIVE： To analyze the different exercise intensities and changes in bone mineral density in type 2 diabetic rat models. METHODS： Forty rats were randomly divided into model group and low-, medium- and high-intensity exercise groups. All rats received intraperitoneal injection of streptozotocin to establish models of type 2 diabetes. Rats in the low-, medium- and high-intensity exercise groups did treadmill training at 10, 20, 30 m/min, 1 hour per day, 6 days as a cycle. They had a rest for 1 day after each cycle, for 8 consecutive cycles. Rats in the model group did not do any exercise. RESULTS AND CONCLUSION： Compared with the model group, the weight of rats was decreased; blood glucose levels were reduced; osteocalcin and serum calcium levels and biomechanical indexes of femur increased; serum phosphorus and alkaline phosphatase decreased in the low-, medium- and high-intensity exercise groups. Bone mineral density increased in the medium- and high-intensity exercise groups. These findings confirmed that different exercise intensities have a certain influence on bone mineral density and bone metabolism in type 2 diabetic rat models. When using a method of treating movement, proper physical exercise can increase serum osteocalcin content, improve bone metabolism, prevent diabetic osteoporosis, and have a high clinical value.
