【摘要】 目的:研究血清25羥维生素D(25-OH-D)、骨特异性碱性磷酸酶(BAP)、抗酒石酸酸性磷酸酶B(TRACP-5b)与2型糖尿病患者胰岛功能及视网膜病变的相关性。方法:收集2018年1月-2019年10月在笔者所在医院住院的116例2型糖尿病患者资料,根据是否合并视网膜病变及病变分期分为无视网膜病变(NDR组)51例,背景期视网膜病变(NPDR组)32例,增殖期视网膜病变(PDR组)33例,选取同期非糖尿病患者30例为对照组,检测25-OH-D、BAP、TRACP-5b及血糖、血脂相关指标,计算体质量(BMI)、C肽的β细胞功能指数(HOMA-β)、C肽抵抗指数(HOMA-CR)。采用Pearson多重线性回归分析相关性。结果:NDR组、NPDR组、PDR组25-OH-D、BAP水平均低于对照组,TRACP-5b水平高于对照组,差异均有统计学意义(P<0.05)。NDR组、NPDR组、PDR组HOMA-β均低于对照组,HOMA-CR均高于对照组,差异均有统计学意义(P<0.05)。PDR组25-OH-D、BAP水平低于NDR组、NPDR组,TRACP-5b水平高于NDR组、NPDR组,NPDR组25-OH-D、BAP水平低于NDR组,TRACP-5b水平高于NDR组,差异均有统计学意义(P<0.05);PDR组HOMA-β低于NDR组、NPDR组,HOMA-CR高于NDR组、NPDR组,NPDR组HOMA-β低于NDR组,HOMA-CR高于NDR组,差异均有统计学意义(P<0.05)。HOMA-β与25-OH-D呈正性相关(r=0.781,P=0.000),与TRACP-5b呈负性相关(r=-0.482,P=0.017),HOMA-CR与BAP呈负性相关(r=-0.619,P=0.007)。结论:骨代谢指标与胰岛功能具有相关性,25-OH-D水平与视网膜病变严重程度相关。

The Correlation between Serum 25-OH-D, BAP, Tracp-5b and Islet Function and Retinopathy in Patients with Type 2 Diabetes Mellitus/LI Yuanyuan, LIN Aiping. //Chinese and Foreign Medical Research, 2020, 18(12): -6
[Abstract] Objective: To study the correlation between serum 25 hydroxyvitamin D (25-OH-D), bone specific alkaline phosphatase (BAP), tartrate resistant acid phosphatase B (tracp-5b) and islet function and retinopathy in type 2 diabetic patients. Method: The data of the 116 patients with type 2 diabetes in our hospital from January 2018 to October 2019 were collected. According to whether or not they combined with retinopathy and the stage of retinopathy, they were divided into three groups, 51 patients with no retinopathy (the NDR group), 32 patients with background retinopathy (the NPDR group), and 33 patients withproliferative retinopathy (the PDR group). At the same time, 30 non-diabetic patients were taken as the control group, 25-OH-D, BAP, tracp-5b, blood glucose and lipid related indexes were detected, body mass (BMI), C-peptide β cell function index (HOMA-β), C-peptide resistance index (HOMA-CR) were calculated. Pearson multiple linear regression was used to analyze the correlation. Result: The levels of 25- OH-D、BAP in NDR group, NPDR group and PDR group were lower than those in the control group, and the levels of TRACP-5b were higher than those in the control group, the differences were statistically significant (P<0.05). The HOMA-β in NDR group, NPDR group and PDR group were lower than that in the control group, and the HOMA-CR were higher than that in the control group, the differences were statistically significant (P<0.05). The levels of 25-OH-D, BAP in the PDR group were lower than those in NDR group and NPDR group, the level of TRACP-5b was higher than that in NDR group and NPDR group, the levels of 25-OH-D, BAP in the NPDR group were lower than those in the NDR group, the level of TRACP-5b in the NPDR group was higher than that in the NDR group, the differences were statistically significant (P<0.05). The HOMA-β in the PDR group was lower than that in NDR group and NPDR group, HOMA-CR was higher than that in NDR group and NPDR group, the HOMA-β in the NPDR group was lower than that in the NDR group, HOMA-CR in the NPDR group was higher than that in the NDR group, the differences were statistically significant (P<0.05). HOMA-β was positively correlated with 25-OH-D (r=0.781, P=0.000), was negatively correlated with TRACP-5b (r=-0.482, P=0.017) and HOMA-CR was negatively correlated with BAP (r=-0.619, P=0.007). Conclusion: There is a correlation between bone metabolism and islet function, and 25-OH-D level is related to the severity of retinopathy.
25(OH)2D3的合成,导致钙吸收障碍。同时由于2型糖尿病患者胰岛素分泌不足,成骨细胞活性受到抑制,成骨和破骨细胞对1,25(OH)2D3的反应降低,骨钙沉积和骨形成减弱[12]。
视网膜病变是糖尿病最常见的微血管并发症之一。相关研究已证实了维生素D水平与糖尿病视网膜病变的病情进展有关。本研究相关性分析显示HOMA-β与25-OH-D呈正性相关,与TRACP-5b呈负性相关,HOMA-CR与BAP呈负性相关。因此骨转换生化指标可作为预测糖尿病视网膜病变及严重程度的参考。
