中文摘要:

目的: 探讨高密度脂蛋白(high-density lipoprotein,HDL)/低密度脂蛋白(low density lipoprotein,LDL)及总Ⅰ型胶原氨基端延长肽(total typeⅠcollagen amino terminal extender peptide,t-PINP)/Ⅰ型胶原羧基端肽β特殊序列(C-terminal peptide of typeⅠcollagen β special sequence,β-CTX)与老年女性骨质疏松椎体骨折(osteoporotic vertebral fractures,OPVFs)风险的相关性。

方法: 回顾性分析2019年1月至2020年12月年龄≥ 60岁的446例女性OPVFs患者的临床资料。根据是否骨折分为无骨折组(186例)和骨折组(260例)。采用单因素分析比较两组年龄、身体质量指数(body mass index,BMI)、骨钙素N段中分子片段(N-terminal mioldle molecular fragment of osteocalcin,N-MID OC)、t-PINP、β-CTX、25-羟基维生素D[25-hydroxyvitamin D,25-(OH) VitD]、血糖(blood sugar,Glu)、总胆固醇(total cholesterol,TC)、甘油三酯(triglyceride,TG)、高密度脂蛋白胆固醇(high-density lipoprtein,HDL)、低密度脂蛋白胆固醇(low-density lipopritein,LDL)、Ca、P、Mg、尿素(urea,UREA)、肌酐(creatinine,Cr)及胱抑素C (Cystatin C,CysC),以及OPVFs与上述各指标间和脂质与骨代谢指标的相关性;采用Logistic回归分析OPVFs与HDL/LDL、t-PINP/β-CTX的风险因素及分层关系。

结果: 无骨折组和骨折组年龄、BMI比较,差异无统计意义(P>0.05)。与无骨折组相比,骨折组HDL、t-PINP/β-CTX、HDL/LDL含量降低,β-CTX含量增加(P<0.05)。OPVFs与β-CTX呈正相关(r=0.110,P<0.05),与HDL、HDL/LDL及t-PINP/β-CTX呈负相关(r=-0.157、-0.175、-0.181,P<0.05)。HDL、HDL/LDL与β-CTX呈负相关(r=-0.22、-0.12,P<0.05),与t-PINP呈负相关(r=-0.13、-0.10,P<0.05);25-(OH) VitD与TC、HDL呈正相关(r=0.11、0.18,P<0.05);HDL/LDL与t-PINP/β-CTX呈正相关(r=0.11,P=0.02)。t-PINP/β-CTX[OR=0.998,95% CI (0.997,1.000),P<0.05]、HDL/LDL[OR=0.228,95% CI (0.104,0.499),P<0.05]为椎体骨折的风险因素,二者三分层显示含量越低,椎体骨折率越高,骨折风险越高,最低层是最高层的2.5、2倍,校正OR分别为2.112[95% CI (1.310,3.404)]、2.331[95% CI (1.453,3.739)]。

结论: 血清低HDL/LDL及t-PINP/β-CTX是老年女性OPVFs的独立危险因素,对椎体骨折风险有较好的预测价值。

Correlation between serum HDL/LDL and t-PINP/β-CTX and osteoporotic vertebral fractures in elderly women
ABSTRACT  

Objective To explore high density lipoprotein (HDL)/low density lipoprotein (LDL) and total typeⅠcollagen amino terminal extender peptide (t-PINP)/C-terminal peptide of typeⅠcollagen β special sequence(β-CTX)and risk of osteoporosis vertebral fractures (OPVFs) in elderly women.

Methods The clinical data of 446 female OPVFs patients aged above 60 years old from January 2019 to December 2020 were retrospectively analyzed. According to whether or not fracture,patients were divided into non-fracture group (186 patients) and fracture group(260 patients). Univariate analysis was performed to analysis age,body mass index(BMI),N-terminal mioldle molecular fragment of osteocalcin,N-MID OC),t-PINP,β-CTX,25-hydroxyvitamin D[25-(OH) VitD],blood sugar (Glu),total cholesterol(TC),high-density lipoprotein (HDL),low-density lipoprotein (LDL),Ca,P,Mg,urea (UREA),creatinine (Cr) and Cystatin C(CysC),and correlation between OPVFs and the above indexes and lipid,bone metabolism indexes between two groups;Logistic regression was performed to analyze risk factors and stratification relationship between vertebral fracture and HDL/LDL,t-PINP/β-CTX. Logistic regression was used to analyze risk factors and stratification relationship between OPVFs and HDL/LDL,t-PINP/β-CTX.

Results There were no signif icant difference in age and BMI between non-fracture group and fracture group (P>0.05). Compared with non-fracture group,contents of HDL,t-PINP/β-CTX and HDL/LDL in fracture group were decreased,and contents of β-CTX were increased (P<0.05). OPVFs was positively correlated with β-CTX (r=0.110,P<0.05),and negatively correlated with HDL,HDL/LDL and t-PINP/β-CTX (r=-0.157,-0.175,-0.181,P<0.05). HDL and HDL/LDL were negatively correlated with β-CTX (r=-0.22,-0.12,P<0.05) and t-PINP (r=-0.13,-0.10,P<0.05). 25-(OH) VitD was positively correlated with TC and HDL (r=0.11,0.18,P<0.05). HDL/LDL was positively correlated with t-PINP/β-CTX(r=0.11,P=0.02). t-PINP/β-CTX[OR=0.998,95%CI(0.997,1.000),P<0.05],HDL/LDL[OR=0.228,95%CI(0.104,0.499),P<0.01] were risk factors for vertebral fracture. The lower levels between two tristratified indicators,the higher the vertebral fracture rate. The risk of fracture was 2.5 and 2 times higher in the lowest stratum than in the highest stratum,with an adjusted OR was[2.112,95%CI(1.310,3.404)] and[2.331,95%CI(1.453,3.739)],respectively.

Conclusion Serum low HDL/LDL and t-PINP/β-CTX are independent risk factors for OPVF in elderly women,and have good predictive value for OPVF risk.
