摘要:

背景:骨骼肌与骨质疏松症关系密切,导致其衰退的主要原因是细胞的凋亡,这种凋亡可能是Caspase家族蛋白所介导的。
目的:探讨补肾健脾方对去势大鼠骨骼肌caspase-3和 caspase-8调控作用。
方法:SD大鼠48只等随机分为对照组、模型组、中药组、西药组,后3组大鼠摘除双侧卵巢建立骨质疏松模型,对照组仅切除周围少量脂肪组织。造模2周后,中药组给予补肾健脾方(2.979 g/kg)灌胃,西药组给予戊酸雌二醇片(0.104 mg/kg)灌胃,模型组和对照组给予蒸馏水灌胃,1次/d。
结果与结论:①干预12周后,双能X线骨密度仪测量发现,相比于对照组,模型组大鼠左侧股骨的骨密度值和骨矿含量均明显降低(P < 0.01);而中药组和西药组的骨密度值均高于模型组(P < 0.05),且2组骨密度值和骨矿含量接近(P > 0.05)。②酶标免疫分析显示,与对照组相比,模型组骨骼肌中Caspase-3和 Caspase-8表达水平明显上升(P < 0.05)。中药能显著降低大鼠骨骼肌中Caspase-3的表达水平(P < 0.05),而西药能显著减低Caspase-8表达水平(P < 0.05)。③说明补肾健脾方对卵巢切除所致的骨质疏松症有明显的治疗作用,能明显提高骨密度,而且能显著减低Caspase-3的水平,但不能显著减低Caspase-8水平,显示补肾健脾方不是通过死亡受体途径去抑制细胞凋亡的。

Abstract:

BACKGROUND: Studies have shown that there is a close relationship between skeletal muscle and osteoporosis. Apoptosis is a main reason of skeletal muscle aging, which may be mediated by the proteins of caspase family.
OBJECTIVE: To study the mechanism of the prescription for tonifying kidney and strengthening spleen on preventing and treating osteoporosis and observe the regulation of the prescription on caspase-3 and caspase-8 expression in skeletal muscle of ovariectomized rats.
METHODS: Forty-eight female non-pregnant SD rats (6 months) were randomly and evenly divided into four groups: control, ovariectomized, estrogen and traditional Chinese herb. After establishing model, the rats of traditional Chinese herb group were intragastrically administered with the prescription for tonifying kidney and strengthening spleen (2.979 g/kg). The rats of estrogen group received an intragastric administration of estradiol valerate (0.104 mg/kg). The rats of the other groups were intragastrically given distilled water, once a day.
RESULTS AND CONCLUSION: Dual energy X-ray absorptiometry results showed that compared with control group, bone mineral density (BMD) and bone mineral content (BMC) in rat left femur were significantly lower in the model group (P < 0.01). The BMD was significantly greater in the estrogen and traditional Chinese herb groups than in the model group (P < 0.05) and the BMD and BMC were similar between the estrogen and traditional Chinese herb groups (P > 0.05). Enzyme linked immunosorbent assay results showed that compared with the control group, caspase-3 and caspase-8 expression in the skeletal muscle was significantly increased in the model group (P < 0.05); caspase-3 expression was significantly decreased in the traditional Chinese herb group (P < 0.05), and caspase-8 expression was significantly decreased in the estrogen group (P < 0.05). These findings suggest that the prescription for tonifying kidney and strengthening spleen exhibits obvious therapeutic effects on ovariectomy-induced osteoporosis, can increase bone mineral density and obviously decrease caspase-3 expression, but it can not markedly decrease caspase-8 expression. This indicates that the prescription does not inhibit apoptosis by death receptor signal pathway.
