文题释义:
白细胞介素:是由多种细胞产生并作用于多种细胞的一类细胞因子。最初是指由白细胞产生又在白细胞间起调节作用的细胞因子。现在是指一类分子结构和生物学功能已基本明确,具有重要调节作用而统一命名的细胞因子,它和血细胞生长因子同属细胞因子。两者相互协调,相互作用,共同完成造血和免疫调节功能。白细胞介素在传递信息,激活与调节免疫细胞,介导T、B细胞活化、增殖与分化及在炎症反应中起重要作用。
骨密度:是骨骼矿物质密度,是骨质量的重要标志之一,用于反映骨质疏松程度及预测骨折危险性。单位是g/cm2,不同的仪器检测方法检测绝对值不同,采用T值判断骨密度,参考值为-1-1,若T<-2.5,则表示发生骨质疏松。


 

背景:研究发现,肿瘤坏死因子α、白细胞介素1β、白细胞介素6分泌量与骨质疏松的形成之间联系紧密。
目的:进一步分析去卵巢大鼠骨组织中肿瘤坏死因子α、白细胞介素1β、白介细胞素6水平及其与骨质疏松形成的关系。
方法:3个月龄雌性SD大鼠60只,根据随机数表法,将大鼠分为对照组和研究组,每组30只。研究组大鼠通过手术去除卵巢,并建立骨质疏松模型,而对照组大鼠保留卵巢,腹腔注射等量生理盐水,实验周期12周。造模后1周检测大鼠血清中雌二醇水平,采用骨密度仪测量大鼠骨密度,并检测骨组织中肿瘤坏死因子α、白介细胞素1β及白介细胞素6水平,分析细胞因子和骨密度之间的相关性。
结果与结论:研究组血清中雌二醇水平明显低于对照组(P=0.007);研究组大鼠腰椎和股骨骨密度显著低于对照组(P=0.006,0.004);研究组骨小梁和成骨细胞占视野面积比例明显低于对照组,而破骨细胞占视野面积比例显著高于对照组(P=0.037,0.029,0.044);与对照组相比,研究组骨组织中肿瘤坏死因子α、白介细胞素1β及白介细胞素6水平明显升高(P=0.032,0.031,0.025);研究组大鼠骨组织中肿瘤坏死因子α、白介细胞素1β及白介细胞素6水平与腰椎和股骨骨密度均呈负相关(P < 0.05)。结果说明,去卵巢大鼠骨组织中肿瘤坏死因子α、白介细胞素1β及白介细胞素6水平升高,破骨细胞占视野面积比例升高,增强破骨活动,骨小梁和成骨细胞占视野面积比例下降,加速骨吸收进程,导致形成骨质疏松。

Abstract:

BACKGROUND: It has found that secretions of tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and interleukin 6 (IL-6) are closely related to osteoporosis

OBJECTIVE: To further investigate the levels of TNF-α, IL-1β and IL-6 of bone tissue in ovariectomized rats and their relationship with osteoporosis.
METHODS: Sixty 3-month-old female Sprague-Dawley rats were randomly divided into control group and test group (n=30 per group). In the test group osteoporosis model was induced by ovariectomy followed by intraperitoneal injection of aluminum nitride solution; while rats in the control group were given intraperitoneal injection of normal saline without ovariectomy. The experiment cycle was 12 weeks. One week after modeling, serum level of estradiol was tested, and the bone mineral density of rats measured with bone densitometry. In the meanwhile, the levels of TNF-α, IL-1β and IL-6 in bone tissue were detected to analyze the correlation between cytokines and bone mineral density.
RESULTS AND CONCLUSION: The level of serum estradiol in the test group was significantly lower than that in the control group (P=0.007); the bone mineral density of the lumbar spine and femur in the test group was significantly lower than that in the control group (P=0.006, 0.004). Compared with the control group, the percentages of trabecular bone and osteoblast area within the visual field in the test group were significantly lower, while the osteoclast area within the visual field was significantly higher (P=0.037, 0.029, 0.044). Compared with the control group, the levels of TNF-α, IL-1β and IL-6 in the test group significantly increased (P=0.032, 0.031, 0.025). And the bone mineral density of the lumbar spine and femur was negatively correlated with the levels of TNF-α, IL-1β and IL-6 in the test group (P < 0.05). In conclusion, the osteoclast activity is enhanced by elevating the levels of TNF-α, IL-1β and IL-6 of bone tissue of ovariectomized rats, and increasing the percentage of osteoclast area within the visual field. Moreover, the percentages of trabecular bone and osteoblast area within the visual field have a decline, which accelerates the process of bone resorption and leads to the formation of osteoporosis.
