摘要:

文题释义:
髋部骨折:指股骨近端骨折,主要包括股骨颈骨折、股骨转子间骨折和股骨转子下骨折,已经成为老年人的常见病和多发病,且具有发病率高、住院率高、致残以及致死率高的特点。
骨代谢指标:主要诊断骨代谢以及骨质吸收情况,对于骨质疏松疾病原因分析以及诊断具有临床重要意义。主要包括血清总Ⅰ型前胶原N-末端前肽、年龄相关的Ⅰ型交联C-端肽和25-羟基维生素D。

背景:髋部骨折和2型糖尿病是老年人的常见病和多发病,其内在的相互联系有待进一步研究。
目的:比较髋部骨折患者合并2型糖尿病与否的骨代谢标志物水平。
方法:2014年8月至2020年8月共有743例髋部骨折患者纳入研究,根据是否有糖尿病病史,将其进一步分为2型糖尿病组(118例)和非2型糖尿病组(625例)。收集并比较两组患者的生化指标(空腹血糖、碱性磷酸酶、三酰甘油、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、血钙和血磷)以及骨代谢参数(总Ⅰ型前胶原N-末端前肽、年龄相关的Ⅰ型交联C-端肽和25-羟基维生素D)。通过Spearman相关分析计算空腹血糖、三酰甘油与骨代谢参数之间的相关性。
结果与结论:①2型糖尿病组患者的空腹血糖和三酰甘油水平显著高于非2型糖尿病组(P < 0.001);②此外,2型糖尿病组患者的总Ⅰ型前胶原N-末端前肽(P=0.017)和年龄相关的Ⅰ型交联C-端肽(P=0.007)水平显著低于非2型糖尿病组;③空腹血糖与年龄相关的Ⅰ型交联C-端肽、空腹血糖与总Ⅰ型前胶原N-末端前肽、三酰甘油与总Ⅰ型前胶原N-末端前肽、血钙与25-羟基维生素D的相关系数分别为-0.124(P < 0.001)、-0.174(P < 0.001)、0.075(P=0.04)和0.108(P=0.003);④该横断面研究发现髋部骨折合并2型糖尿病患者的骨转换状态(骨形成和骨吸收)较低;空腹血糖水平与总Ⅰ型前胶原N-末端前肽和年龄相关的Ⅰ型交联C-端肽水平呈负相关;此外,良好的血糖控制可能有利于骨骼代谢并防止髋部骨折后骨折延迟愈合。
缩略语:总Ⅰ型前胶原N-末端前肽:total procollagen type 1 N-terminal propeptide,TP1NP;年龄相关的Ⅰ型交联C-端肽:age-related typeⅠcross linked C-telopeptide,CROSSL

Abstract: BACKGROUND: Hip fracture and type 2 diabetes mellitus are common and frequently-occurring diseases in older adults and their internal relationship needs further studies.
OBJECTIVE: To compare the levels of bone metabolism markers between type 2 diabetes mellitus and non-type 2 diabetes mellitus patients with hip fracture.
METHODS: Total 743 patients with hip fracture from August 2014 to August 2020 were enrolled in this study. According to the presence or absence of diabetes history, they were further divided into type 2 diabetes mellitus group (T2DM group, n=118) and non-type 2 diabetes mellitus group (non-T2DM group, n=625). Biochemical parameters (fasting blood glucose, alkaline phosphatase, triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, blood calcium, and blood phosphorus) and bone metabolism parameters (total serum procollagen type N-terminal propeptide, the age-related type I cross linked C-telopeptide and 25-hydroxyvitamin D) were collected and compared. The correlation between fast blood glucose and triglyceride and bone metabolism parameters was calculated by the Spearman correlation analysis.
RESULTS AND CONCLUSION: The fast blood glucose and triglyceride levels in the T2DM group were significantly higher than those in the non-T2DM group. In addition, the total serum procollagen type N-terminal propeptide (P=0.017) and total serum procollagen type N-terminal propeptide (P=0.007) levels in the T2DM group were significantly lower than those in the non-T2DM group. The correlation coefficients between fasting blood glucose and age-related type I cross linked C-telopeptide, between fasting blood glucose and total serum procollagen type N-terminal propeptide, between triglyceride and total serum procollagen type N-terminal propeptide, and between blood calcium and 25-hydroxyvitamin D were -0.124 (P < 0.001), -0.174 (P < 0.001), 0.075 (P=0.04), and 0.108 (P=0.003), respectively. This cross-sectional study indicated that there is a low bone turnover state (both bone formation and bone resorption) in patients with type 2 diabetes mellitus after hip fractures and the fasting blood glucose levels is negatively correlated with total serum procollagen type N-terminal propeptide and age-related type I cross linked C-telopeptide levels. In addition, good glucose control may be beneficial to bone metabolism and prevent from delayed fracture healing after hip fracture.

Key words: hip fracture, osteoporosis, type 2 diabetes mellitus, bone metabolism marker, fracture healing
