【摘要】：目的:觀察龜板聯(lián)合阿倫磷酸鈉(ALN)對激素性骨質(zhì)疏松(GIOP)大鼠腰椎Runx2、CTSK表達(dá)的影響。方法:40只3月齡雌性SD大鼠隨機(jī)分為4組:空白組、模型組、ALN組、龜板聯(lián)合ALN組(聯(lián)合組)。模型組、ALN組及聯(lián)合組皮下注射地塞米松造模,成功后分別用0.9%氯化鈉溶液、ALN和龜板聯(lián)合ALN進(jìn)行灌胃。12周后取大鼠腰椎進(jìn)行:micro-CT檢測腰椎骨微細(xì)結(jié)構(gòu)、HE染色觀察骨組織形態(tài)學(xué),qPCR及Western blot分別檢測腰椎Runx2、CTSK mRNA和蛋白表達(dá)。結(jié)果:與空白組比較,模型組Tb.N、Tb.Th明顯下降(P0.01),Tb.Sp、CTSK mRNA和蛋白表達(dá)明顯升高(P0.01),Runx2 mRNA和蛋白表達(dá)呈下調(diào)趨勢;與模型組比較,ALN組和聯(lián)合組BS/TV、Tb.N、Tb.Th、Runx2蛋白表達(dá)明顯升高(P0.01),Tb.Sp、CTSK mRNA和蛋白表達(dá)明顯下調(diào)(P0.01)。結(jié)論:龜板聯(lián)合阿倫磷酸鈉抗大鼠腰椎GIOP的協(xié)同機(jī)制可能與調(diào)節(jié)Runx2、CTSK的表達(dá)密切相關(guān)。
[Abstract]:Objective: To observe the effect of Plastrum Testudinis combined with Allen sodium phosphate (ALN) on glucocorticoid induced osteoporosis (GIOP) rats lumbar Runx2, CTSK expression. Methods: 40 March old female SD rats were randomly divided into 4 groups: control group, model group, ALN group, combined group ALN (combined group). The model of turtle shell group, ALN group and combined group subcutaneous injection of dexamethasone model, after the success of Sodium Chloride Solution ALN and 0.9% respectively, combined with ALN.12 by gavage Testudinis weeks after rat lumbar micro-CT detection of lumbar bone micro structure of bone tissue morphology, HE staining, qPCR and Western blot respectively to detect expression of CTSK mRNA Runx2 of the lumbar spine. And protein. Results: compared with the control group, Tb.N model group, Tb.Th decreased significantly (P0.01), Tb.Sp, mRNA and expression of CTSK protein increased significantly (P0.01), the expression of Runx2 mRNA and protein decreased; compared with the model group, ALN group and combined group BS/TV, Tb.N, Tb.Th, Runx2 protein expression in Ming Dynasty Xian Shenggao (P0.01), Tb.Sp, mRNA and protein expression of CTSK was significantly reduced (P0.01). Conclusion: the coordination mechanism of sodium phosphate in rats with Allen turtle lumbar GIOP may be related to the regulation of Runx2, the expression of CTSK is closely related.
