研究目的:

1.糖尿病并发症的智能诊断新技术有效性研究 采集糖尿病患者的超声(颈动脉和下肢血管)、磁共振(颅脑磁共振)和计算机断层扫描影像(冠状动脉计算机断层扫描血管造影),将课题2建立的糖尿病并发症智能诊断新技术分别用于并发症影像诊断,以三甲医院专家组的诊断结果为金标准,通过对两组的诊断结果进行一致性检验,评估人工智能诊断新技术的有效性。 2.糖尿病并发症智能筛查新技术有效性的多中心临床研究 开展针对糖尿病患者的全国多中心临床研究。以《国家基层糖尿病防治管理管理指南(2021)》指南对糖尿病人群进行糖尿病视网膜病变、肾脏病变、颈动脉粥样硬化、下肢血管病变、认知功能障碍等慢性并发症检查,同时应用课题2开发的基于糖尿病并发症智能筛查新技术对上述糖尿病人群进行糖尿病慢性并发症筛查,以公认的糖尿病慢性并发症临床诊断标准为金标准,评估智能筛查新技术的有效性。 3.糖尿病并发症智能预警新技术的有效性临床研究 在基线时,所有研究对象接受临床常规的糖尿病并发症和代谢情况评估,随后将研究对象划分为无糖尿病并发症组和伴有糖尿病并发症组,进行2年随访。应用课题2开发的糖尿病并发症智能预警技术对患者基线并发症发生发展风险进行评估,通过比较高、低风险组慢性并发症的发生、发展情况,从而验证糖尿病并发症智能预警新技术的有效性。  

Objectives of Study:

1.​​A Study on the Effectiveness of a Novel Intelligent Diagnostic Technology for Diabetic Complications:​​ This research involves collecting ultrasonographic images (carotid and lower limb vessels), magnetic resonance imaging (cranial MRI), and computed tomography angiography images (coronary CTA) from diabetic patients. The novel intelligent diagnostic technology for diabetic complications, developed in Project 2, will be applied to diagnose complications using this imaging data. To assess its effectiveness, the diagnostic results generated by the AI technology will be compared against the gold standard diagnosis provided by an expert panel from tertiary hospitals, with a consistency test conducted between the two sets of results. 2.Multicenter Clinical Study on the Effectiveness of Novel Intelligent Screening Technology for Diabetic Complications​​ A nationwide multicenter clinical study will be conducted in diabetic patients. Chronic complications (e.g., diabetic retinopathy, nephropathy, carotid atherosclerosis, lower extremity vascular disease, cognitive impairment) will be examined per the National Primary Diabetes Prevention and Management Guidelines (2021). Concurrently, the novel intelligent screening technology for diabetic complications developed in Project 2 will be applied to this cohort. Using established clinical diagnostic criteria for diabetic complications as the gold standard, the effectiveness of the intelligent screening technology will be evaluated. ​​3.Effectiveness Study on Novel Intelligent Diagnosis Technology for Diabetic Complications​​ At baseline, all subjects will undergo routine clinical assessments for diabetic complications and metabolic status, followed by stratification into non-complication and complication groups for a 2-year follow-up. Project 2’s novel intelligent early-warning technology will evaluate patients' baseline risk of complication onset/progression. Validation of the technology’s effectiveness will be achieved by comparing the occurrence and progression of chronic complications between high- and low-risk groups.

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

1.智能诊断新技术 本研究采取中心化读片,由三级医院的专科医生依据《颈部血管超声若干问题专家共识》《腹部及四肢动脉超声若干常见临床问题专家共识》《常用脑影像技术在脑卒中诊断中的应用指南》进行糖尿病并发症图像的判读。若2人诊断结果一致,则作为诊断的金标准。若2人诊断结果不一致,由权威专家进行最终判读,给出诊断结果作为金标准。 2.智能筛查与预警新技术 (1)糖尿病视网膜病变:采用2003年《糖尿病视网膜病变国际临床分级标准》的标准; (2)糖尿病肾脏病变:采用《中国糖尿病肾脏病防治指南(2021年版)》的标准; (3)颈动脉粥样硬化:使用颈动脉超声检测颈动脉内中膜厚度和斑块等指标来评估; (4)下肢血管病变:使用下肢血管超声检测血管及斑块的情况; (5)糖尿病认知功能障碍:通过蒙特利尔认知评估量表评估糖尿病患者的认知功能。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

1.New Technology in Intelligent Diagnosis This study uses centralized image reading, where specialists from tertiary hospitals interpret images of diabetes complications based on the "Expert Consensus on Ultrasound of Cervical Vessels," "Expert Consensus on Common Clinical Issues in Abdominal and Limb Artery Ultrasound," and the "Guidelines for the Use of Common Brain Imaging Techniques in Stroke Diagnosis." If the diagnoses of two doctors are consistent, their conclusion is taken as the diagnostic gold standard. If the diagnoses of two doctors are inconsistent, an authoritative expert provides the final interpretation, which serves as the diagnostic gold standard. 2.
