【目的】 探究胰岛素抵抗指标[甘油三酯-葡萄糖(TyG)指数]及炎症指标[中性粒细胞与淋巴细胞比值(NLR)、C反应蛋 白(CRP)]与糖尿病肾脏疾病(DKD)合并颈动脉粥样硬化(CAS)患者中医证型之间的相关性。【方法】 采用回顾性分析方法,纳 入 300 例 DKD 合并 CAS 患者作为病例组,并同期选取 30 例 DKD 非 CAS 患者作为对照组。通过比较 2 组患者的 TyG 指数、 NLR、CRP水平差异,分析这些指标与颈动脉内膜中层厚度(IMT)、斑块面积的关系,以及不同中医证型下TyG指数、NLR、 CRP的水平变化。采用Logistic回归分析和受试者工作特征(ROC)曲线评估TyG指数、NLR、CRP在预测DKD合并CAS斑块 稳定性及预后中的应用价值。【结果】(1)DKD 合并 CAS 患者的 TyG 指数、NLR、CRP 水平均显著高于 DKD 患者(P<0.01)。 (2)TyG 指数、NLR、CRP 与 IMT、斑块面积呈显著正相关关系(P<0.01)。(3)DKD 合并 CAS 中不稳定斑块患者的 TyG 指数、 NLR、CRP 水平均明显高于稳定斑块患者(P<0.01)。(4) DKD 合并 CAS 患者的中医证型分布中,气阴两虚证占比最高 (33.33%),其次为脾肾阳虚证(28.67%)、阴阳两虚证(22.00%)和浊毒瘀阻证(16.00%)。(5)不同中医证型DKD合并CAS患者 的 TyG指数、NLR、CRP水平从高到低均依次为浊毒瘀阻证、阴阳两虚证、脾肾阳虚证、气阴两虚证。(6)Logistic回归分析 结果显示,TyG指数、NLR、CRP水平与 DKD合并 CAS患者的斑块稳定性密切相关(P<0.05或 P<0.01)。(7) ROC曲线分析 表明,TyG指数、NLR、CRP在鉴别DKD合并CAS预后方面具有较高的价值(P<0.01)。【结论】 TyG指数、NLR、CRP有望成 为DKD合并CAS中医微观辨证及预后评估的潜在生物学指标。

Objective To investigate the correlation between insulin resistance markers [triglyceride-glucose (TyG) index], inflammatory indicators [neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP)], and traditional Chinese medicine (TCM) syndromes in patients with diabetic kidney disease (DKD) complicated by carotid atherosclerosis (CAS). Methods This retrospective study enrolled 300 DKD patients with CAS (case group) and 30 DKD patients without CAS (control group). Differences in TyG index,NLR,and CRP levels were compared between groups. The relationships between these markers and carotid intima-media thickness (IMT)/ plaque area were analyzed, along with their variations across TCM syndromes. Logistic regression and receiver operating characteristic (ROC) curve analyses were performed to evaluate the predictive value of TyG index,NLR, and CRP for plaque stability and prognosis. Results(1) The TyG index,NLR,and CRP levels in patients with DKD and CAS were significantly higher than those in patients with DKD alone (P<0.01).(2) The TyG index, NLR,and CRP were significantly positively correlated with IMT and plaque area (P<0.01).(3) In patients with DKD combined with CAS, the TyG index, NLR, and CRP levels in those with unstable plaques were significantly higher than those with stable plaques (P<0.01).(4) Among the distribution of TCM syndromes in patients with DKD combined with CAS,the qi and yin deficiency syndrome had the highest proportion (33.33%), followed by spleen and kidney yang deficiency syndrome (28.67%),yin and yang deficiency syndrome (22.00%), and turbid toxin and stasis obstruction syndrome (16.00%).(5) Among patients with DKD and CAS,the TyG index,NLR,and CRP levels in patients with different TCM syndromes decreased in the following order:turbid toxin and stasis obstruction syndrome, yin and yang deficiency syndrome, spleen-kidney yang deficiency syndrome,and qi and yin deficiency syndrome.(6) Logistic regression analysis results showed that TyG index, NLR, and CRP levels were closely associated with plaque stability in patients with DKD combined with CAS (P<0.05 or P<0.01).(7)ROC analysis showed that these markers have high prognostic value in DKD-CAS (P<0.01). Conclusion TyG index, NLR, and CRP may serve as potential biomarkers for TCM syndrome differentiation and prognosis assessment in DKD-CAS.
