-
摘要:
目的 研究慢性肾脏病(chronic kidney disease,CKD)患者血清中的缺氧诱导因子-1α(hypoxia inducible factors-1α,HIF-1α)的表达情况,分析其与血清纤维化指标Ⅲ型前胶原氨基末端肽(type Ⅲprocollagen amino terminal peptide,PⅢNP)、CKD患者临床指标的关系,探讨HIF-1α在CKD中的临床应用价值。 方法 随机抽取63例CKD患者为研究对象,根据CKD分期对研究对象进行分组,CKD1~2期30例患者为A组,CKD3期17例患者为B组,CKD4~5期16例患者为C组,ELISA法检测入组患者血清中HIF-1α及PⅢNP的表达,同时收集入组患者的临床资料,包括姓名、性别、年龄、血常规、肝功能、肾功能、离子、24 h尿蛋白。 结果 HIF-1α与PⅢNP、血肌酐(serum creatinine,Scr)、血尿素氮(blood urea nitrogen,BUN)、γ-谷氨酰转肽酶(γ-glutamyltranspeptidase,γ-GT)呈正相关(P < 0.05),而与肾小球滤过率(glomerular filtration rate,GFR)、血红蛋白(hemoglobin,HB)、血钙呈负相关( P < 0.05),与中性粒细胞与淋巴细胞比值(neutropil-to-lymphocyte ratio,NLR)、血小板与淋巴细胞比值(platelet-to-lymphocyte ratio,PLR)、白蛋白(albumin,ALB)、血磷、24 h尿蛋白无相关性( P > 0.05)。 结论 HIF-1α与血清纤维化指标PⅢNP、肾功能、CKD并发症相关,可能参与CKD疾病的进展,可作为评价CKD的指标之一。 Abstract:Objective To study the expression of HIF-1α in the serum of CKD patients, analyze the relationship between it and serum fibrosis index PⅢNP, and the clinical indicators of CKD patients, and explore the clinical application value of HIF-1α in CKD. Methods A total of 63 CKD patients were randomly selected as the research object, and the research objects were grouped according to the CKD stage. 30 patients in CKD1-2 were in group A, 17 patients in CKD3 were in group B, and 16 patients in CKD4-5 were in group C.ELISA method was used to detect the expression of HIF-1α and PⅢNP in the serum of the enrolled patients, and the clinical data of the enrolled patients were collected, including gender, age, blood routine, liver function, renal function, ions, and 24-hour urine protein. Results HIF-1α was positively correlated with PⅢNP, Scr, BUN, γ-GT(P < 0.05), negatively correlated with GFR, HB, Blood calcium( P < 0.05), There was no correlation with NLR, PLR, ALB, Phosphorus and 24-hour urine protein( P > 0.05). Conclusion HIF-1α is associated with serum fibrosis indexes, renal function, CKD complications, and may be involved in the progression of CKD disease, which can be used as one of the indicators for evaluating CKD. -
