Objective: This experimental study is based on earlier animal and clinical experiment, drawn thinkings of combinations with two methods and pursued a synthesis method of high-efficiency, cheap and convenient calcium and exercise treatment. We adopt taking natural-clam's casing powder and preconcereted-intensity excises to intervene shape of osteoporosis in gelded rats, than we compare the indexes such as the biomechanics indexes of the right femur and the third lumbar vertebrae, the weight and uterus quotiety of rats before the experiment to these indexes after the experiment. We hope to find better and suitable way to prevent and treat the postmenopausal osteoporosis and offer reference for clinic.

目的 本实验的主要目的是在前期动物实验的基础上，引入两种方式联合干预的思维，立足于探求既高效又经济、方便的补钙剂加上与运动疗法相联合的方式，对切除雌性大鼠卵巢而复制成的骨质疏松症模型进行服用天然贝类蛤蜊壳粉，同时施以预定强度的运动刺激的方法，再通过试验前后大鼠体重、子宫指数的变化及大鼠股骨和椎体生物力学指标的对比变化进行分析，以期探索出防治绝经后骨质疏松症的更好的、更适宜于大众的手段；并为天然钙剂和运动联合作用防治PMOP提供参考。

A pH-responsive controlled releasing carrier for medicine is a chitosan-base gel which is prepared from Chitosan, gelatin and pectin through cross-linking by aldehyde cross-linking agents, and features obvious pH dependency, high biocompatibility and abling to biologically degradate. It can be used for detention-type controlled releasing medicines to avoid toxic' by-effect due to excess dosage.

一种pH响应性药物控释载体，采用壳聚糖、明胶和果胶等天然高分子材料用醛类交联剂共交联合成了壳聚糖基凝胶，用该凝胶制备的药物释放体系呈明显的pH依赖性，用于口服抗酸、治疗胃肠疾患的滞留型控释制剂，可避免释放药量过度导致的毒副作用，且该控释载体生物相容性好、可生物降解。

Flex family of three pillows: Soft Pillow, fiber cotton pillows, silk, feather pillow filling and other basic material, comfortable and flexible Product; hard Pillow, the people gradually, and enjoy popular buckwheat shell filled material, mobility, and be free to shape the shape, in particular the best load bearing capacity to have a growing number of loyal followers; neutral pillow (Mid-Firm Pillow), natural Typha velvet, slightly elastic material, such as Kapok Morrison, but the natural aroma, comfortable and soft, and the support of the cervical spine in particular, see favorite moderate.
