摘要:

文题释义:
骨质疏松:是以骨量减少、骨的微观结构退化为特征的,致使骨的脆性增加以及易于发生骨折的一种全身性骨胳疾病,是骨科及老年科等相关科室常见病、多发病。
H2S:内源性H2S在体内多种系统的生理及病理生理方面起着重要作用,通过细胞内外信号传递途径调节许多重要的细胞功能,被认为是继一氧化氮和一氧化碳后发现的第3种内源性气体信号分子。外源性H2S可以通过ERK1/2依赖的抗氧化机制刺激成骨细胞的形成和分化,在体外细胞实验中成功抑制了双氧水诱导的成骨细胞株系MC3T-E1氧化损伤。


背景:外源性硫化氢(H2S)对成骨细胞的形成和分化有重要的影响,成骨细胞是骨质疏松疾病发生发展的重要功能细胞,而外源性H2S对骨质疏松水平及相关激素的影响尚未见研究。
目的:探讨内源性H2S浓度与骨质疏松的相关性,以及补充外源性H2S对骨代谢临床随访常用生化、激素指标的影响。
方法:纳入60只大鼠,随机分为3组(n=20),模型组、外源性H2S组通过切除大鼠双侧卵巢建立经典的骨质疏松模型,假手术组进行假手术处理,不做卵巢切除术。假手术组、模型组大鼠腹腔注射1 mg/kg生理盐水,外源性H2S组大鼠腹腔注射100 μg/kg 外源性H2S缓释剂GYY4137,用药频率均为2 d 1次,实验期为12周。定量对比分析各组大鼠血浆H2S水平、血钙和血磷浓度以及血浆碱性磷酸酶活性、骨钙素、降钙素、甲状旁腺素、瘦素表达水平。
结果与结论:①与假手术组相比,给药第8,12周模型组大鼠L5骨密度、血浆H2S、钙、磷、碱性磷酸酶、降钙素水平显著降低,骨钙素、甲状旁腺素、瘦素水平则显著升高(P < 0.05);②与假手术组相比,给药第8,12周外源性H2S组L5骨密度、血浆H2S、磷、骨钙素、降钙素、甲状旁腺素和瘦素差异无显著性意义(P > 0.05),而血浆钙水平、碱性磷酸酶活性仍降低(P < 0.05);③与模型组相比,外源性H2S组血浆H2S、钙、磷水平升高,瘦素水平降低(P < 0.05),而给药第8,12周L5骨密度、碱性磷酸酶活性、骨钙素、降钙素、甲状旁腺素水平差异均无显著性意义(P > 0.05);④结果表明,内源性H2S浓度与去势大鼠骨质疏松模型的骨质疏松病情呈现负相关关系,外源性补充提高血浆H2S浓度可以改善或反转血浆钙、磷和部分骨代谢激素指标水平;提示血浆H2S浓度与骨质疏松存在相关性,补充外源性H2S对因雌激素减少导致的骨质疏松症具有潜在治疗效果。

Abstract: BACKGROUND: Exogenous hydrogen sulfide has an important effect on the formation and differentiation of osteoblasts, which are important functional cells in the development of osteoporotic disease. The effect of exogenous hydrogen sulfide on osteoporosis levels and related hormones has not been studied.
OBJECTIVE: To investigate the correlation between endogenous hydrogen sulfide concentration and osteoporosis, and the effect of exogenous hydrogen sulfide supplementation on the biochemical and hormonal parameters commonly used in the clinical follow-up of bone metabolism. 
METHODS: Sixty rats were randomly divided into sham-operated group, model group, and exogenous hydrogen sulfide group (n=20 per group). A classical osteoporosis model was established by removing both ovaries of rats in the latter two groups. No ovariectomy was conducted in the sham-operated group. Rats in the sham-operated and model groups were intraperitoneally given 1 mg/kg normal saline, while those in the exogenous hydrogen sulfide group intraperitoneally injected 100 μg/kg GYY4137, a slow-released agent of exogenous hydrogen sulfide. Treatments in each group were conducted twice a day, for 12 weeks. Plasma hydrogen sulfide concentration, blood calcium and phosphorus concentrations, alkaline phosphatase activity, osteocalcin, calcitonin, parathyroid hormone, and leptin laboratory index data of each group were analyzed by quantitative comparison. 
RESULTS AND CONCLUSION: Bone mineral density of the L5, plasma hydrogen sulfide, calcium, phosphorus, alkaline phosphatase, calcitonin concentrations were significantly lower, and osteocalcin, parathyroid hormone, and leptin levels were significantly higher in the model group compared with the sham-operated group at weeks 8 and 12 (P < 0.05). There were no significant differences between the sham-operated and exogenous hydrogen sulfide groups at weeks 8 and 12 in terms of L5 bone mineral density, plasma hydrogen sulfide, phosphorus, osteocalcin, calcitonin, parathyroid hormone and leptin levels (P > 0.05). Whereas blood calcium concentration and alkaline phosphatase activity were still decreased in the exogenous hydrogen sulfide group compared with the sham-operated group (P < 0.05). Compared with the model group, plasma hydrogen sulfide, blood calcium and phosphorus concentrations were elevated and leptin level was decreased in the exogenous hydrogen sulfide group (P < 0.05), while the differences in L5 bone mineral density, alkaline phosphatase activity, osteocalcin, calcitonin and parathyroid hormone levels at weeks 8 and 12 were not significant between the two groups (P > 0.05). Therefore, in the ovariectomized osteoporotic rat model, endogenous hydrogen sulfide concentration was negatively correlated with the severity of osteoporosis, and exogenous supplementation to increase plasma hydrogen sulfide concentration could improve or reverse plasma calcium, phosphorus and some hormone indexes related to bone metabolism. To conclude, plasma hydrogen sulfide concentration and osteoporosis are correlated, and exogenous hydrogen sulfide supplementation has a potential therapeutic effect on osteoporosis which is caused by estrogen reduction.
