摘要:

文题释义:

骨坏死:亦被称为无菌性坏死或骨缺血性坏死,其特点是骨组织的血液供应减少或中断,导致骨细胞死亡,可以影响身体任何骨骼,最常见是股骨头,其次是肱骨头及其他关节,常表现为关节疼痛、关节僵硬、行走困难及肌肉无力等症状。
孟德尔随机化:是一种创新的流行病学研究方法,它运用遗传变异作为工具变量,来评估特定暴露因素与结局因素之间的潜在因果关系,遗传变异随机地分配给后代,这有助于消除观察性研究中常见的混杂因素和反向因果关系的影响。

摘要
背景:中国骨坏死疾病患者的基数庞大,迫切需要寻找新的预防靶点以制定更为有效的治疗策略。代谢组学研究表明,人体代谢物与骨坏死之间存在关联性,然而血液代谢物与骨坏死之间的因果关系尚未明确。
目的:通过双样本的孟德尔随机化分析探讨血液代谢物与骨坏死之间的因果关系。
方法:收集486种血液代谢物(暴露因素)与骨坏死(结局因素)的公共数据,其中486种血液代谢物数据源自2014年发表在《Nature Genetics》杂志上对血液代谢物进行的全基因组关联估计,该研究涵盖了7 824名欧洲成年人;骨坏死的单核苷酸多态性数据来源于芬兰的FinnGen公共数据库R11数据集,包含了总计431 614个样本和21 306 430个单核苷酸多态性位点的信息,其中骨坏死病例为1 788例,对照组为429 826例,所有参与者均为欧洲裔人群。利用Rstudio软件进行孟德尔随机化分析(逆方差加权法、MR-Egger法和加权中位数法),再对结果进行异质性检验、基因水平多效性检验及Steiger方向性检验,确保结果的稳健性和可靠性。
结果与结论:①鉴定出16种血液代谢物与骨坏死存在显著的因果关系(P逆方差加权法 < P错误发现率 < 0.05);②8种血液代谢物能增加患骨坏死的风险(包括4种已知代谢物和4种未知代谢物),具体为泛酸、β-羟基异戊酸、马尿酸盐、水杨酸葡糖苷酸、X-08766、X-11452、X-12776和X-14662;③8种血液代谢物能降低骨坏死的风险(6种已知代谢物和2种未知代谢物),包括皮质醇、1-棕榈酰甘油、焦谷氨酰甘氨酸、二棕榈酰甘油磷胆碱、对甲酚硫酸盐、乙硫氨酸、X-06307、X-12092;④上述结果提示16种血液代谢物与骨坏死之间存在因果关系,未来有望成为干预骨坏死发生和治疗的潜在靶点;⑤尽管当前尚缺乏大规模亚洲人群的相关数据,此次研究基于欧洲人群数据仍可为中国骨坏死领域的研究提供重要的参考价值,未来国内医学工作者或许可以通过调节代谢物水平来实现对骨坏死的精准干预;此外,基于此次研究结果,相关研究者还可以进一步探讨代谢物在中药治疗骨坏死过程中的作用机制,这不仅有助于深化对传统中医药疗法的理解,还将促进中西医结合的研究进展,推动开发更适合中国人群特点的个性化治疗方案。

Abstract: BACKGROUND: In China, the patient population with osteonecrosis is large, and there is an urgent need to find new preventive targets to develop more effective treatment strategies. Metabolomics studies have shown that there is an association between human metabolites and osteonecrosis, but the causal relationship between blood metabolites and osteonecrosis has not yet been clarified.
OBJECTIVE: To investigate the causal relationship between blood metabolites and osteonecrosis through two-sample Mendelian randomization analysis.
METHODS: The public data of 486 blood metabolites (exposure factors) and osteonecrosis (outcome factors) were collected. Data of 486 blood metabolites were derived from a genome-wide association estimate for blood metabolites published in Nature Genetics in 2014, which covered 7 824 European adults. The single nucleotide polymorphism data for osteonecrosis were obtained from the FinnGen public database R11 dataset, containing information on a total of 431 614 samples and 21 306 430 single nucleotide polymorphism loci, with 1 788 cases of osteonecrosis and 429 826 controls, with all participants being of European descent. Mendelian randomization analysis (inverse variance weighting method, MR-Egger method, and weighted median method) was performed by Rstudio software, and then the heterogeneity test, horizontal pleiotropy test and Steiger directionality test were performed to ensure the robustness and reliability of the results.
RESULTS AND CONCLUSION: (1) Sixteen blood metabolites were identified as having a significant causal relationship with osteonecrosis (Pinverse variance weighting < 
Pfalse discovery rate < 0.05). (2) Eight blood metabolites increased the risk of osteonecrosis (including four known metabolites and four unknown metabolites), specifically pantothenate, beta-hydroxyisovalerate, hippurate, salicyluric glucuronide, X-08766, X-11452, X-12776 and X-14662. (3) Eight blood metabolites could reduce the risk of osteonecrosis (six known metabolites and two unknown metabolites), including cortisol, 1-palmitoylglycerol (1-monopalmitin), pyroglutamyl glycine, 2-stearoylglycerophosphocholine, p-cresol sulfate, ergothioneine, X-06307, X-12092. (4) The above results suggest that there is a causal relationship between 16 blood metabolites and osteonecrosis, which is expected to be a potential target for intervention in the occurrence and treatment of osteonecrosis in the future. (5) Despite the lack of relevant data from large-scale Asian populations at present, this study provides important reference value for the field of osteonecrosis in China based on European population data. In the future, domestic medical workers may be able to achieve precise intervention for osteonecrosis by regulating metabolite levels. In addition, based on the results of this study, relevant researchers can further explore the mechanism of action of metabolites in the treatment of osteonecrosis with traditional Chinese medicine, which not only helps to deepen the understanding of traditional Chinese medical therapies but also promotes the progress of integrated traditional Chinese and Western medicine research, driving the development of personalized treatment plans that are more suitable for the characteristics of the Chinese population.
