尿酸与支气管肺发育不良相关性研究进展

Advances in Research on the Association between Uric Acid and Bronchopulmonary Dysplasia

摘要: 支气管肺发育不良(Bronchopulmonary Dysplasia, BPD)是早产儿的慢性肺部疾病，其发病机制复杂且多因素交织，涉及到氧化应激、炎症反应等多个环节。尿酸(UA)在支气管肺发育不良(BPD)中的角色逐渐得到重视。尿酸不仅在氧化应激(OS)中发挥着关键抗氧化作用，同时也与炎症反应的调控密切相关。在婴儿特别是早产儿中，尿酸水平的升高与BPD的发病率呈正相关，提示尿酸可能通过氧化应激与炎症机制对肺部发育产生影响。相关研究发现，尿酸通过影响细胞因子(cytokines)的释放及免疫响应，可能促进肺组织细胞的炎症状态，并影响肺泡发育进程。为了深入理解尿酸在BPD过程中所发挥的作用，未来的研究应着重于尿酸与诱导性因子之间的相互作用及其生物学效应，同时开发基于尿酸水平的临床干预措施，以探索个体化治疗的可行性及有效性。总体而言，尿酸作为BPD的重要生物指标，值得在临床预测及干预策略中进一步研究。

Abstract: Bronchopulmonary dysplasia (BPD) is a chronic lung disease of premature infants. Its pathogenesis is complex and multi-factor, involving oxidative stress, inflammatory response and other links. The role of uric acid (UA) in bronchopulmonary dysplasia (BPD) has been paid more and more attention. Uric acid not only plays a key antioxidant role in oxidative stress (OS), but also is closely related to the regulation of inflammatory response. In infants, especially premature infants, the increase of uric acid level is positively correlated with the incidence of BPD, suggesting that uric acid may affect lung development through oxidative stress and inflammation. Relevant studies have found that uric acid may promote the inflammatory state of lung tissue cells and affect alveolar development by affecting the release of cytokines and immune response. To better understand the role of UA in BPD, future research should focus on the interaction between UA and inducing factors and their biological effects, and develop clinical interventions based on UA levels to explore the feasibility and effectiveness of individualized treatment. In conclusion, as an important biological indicator of BPD, uric acid is worthy of further study in clinical prediction and intervention strategies.
