血清C_肽、尿微量白蛋白与糖化血红蛋白应用于糖尿病肾病诊断中的效果分析

血清C肽、尿微量白蛋白与糖化血红蛋白应用于糖尿病肾病诊断中的效果分析陈丹,胡丽,王彬阶麻城市人民医院检验科,湖北麻城438300[摘要]目的探究血清C肽(C-PR)、尿微量白蛋白(mAlb)与糖化血红蛋白(HbA1c)应用于糖尿病肾病(dia‐betic nephropathy, DN)的诊断效果。
方法回顾性分析2021年4月—2022年4月麻城市人民医院检验科收治的95例糖尿病(diabetes mellitus, DM)患者的临床资料,依据是否合并肾病划分为DM组(50例)、DN组(45例),基于相同时期选取到本院接受健康体检的志愿者60名作为对照组,均接受C-PR、mAlb、HbA1c检测,分析联合检测效果。
结果DN组C-PR水平最低,对照组最高,DN组mAlb、HbA1c水平最高,对照组最低,差异有统计学意义(P<0.05)。
联合检测诊断灵敏度97.78%、特异度93.33%,均显著高于C-PR、mAlb或HbA1c单一检测结果,差异有统计学意义(P<0.05)。
结论在DN患者中实施C-PR、mAlb、HbA1c联合检测具有较高的诊断价值,便于患者尽早得到有效治疗。

Methods Retrospective analysis was made on the clinical data of 95 patients with diabetes mellitus (DM) admitted to the Laboratory Department of Macheng People′s Hospital from April 2021 to April 2022. They were divided into DM group (50 cases) and DN group (45 cases) according to whether they were complicated with kidney disease or not. Based on the same period, 60 volunteers who received physical ex‐amination in our hospital were selected as the control group, all of whom received C-PR, mAlb, and HbA1c tests, and the effect of the joint test was analyzed. Results The C-PR level in the DN group was the lowest, while the control group was the highest, the levels of mAlb and HbA1c in the DN group were the highest, while the control group was the lowest, the difference was statistically significant (P<0.05). The diagnostic sensitivity and specificity of the com‐bined test were 97.78% and 93.33%, which were significantly higher than those of the single test results of C-PR, mA1b, or HbA1c, and the difference was statistically significant (P<0.05). Conclusion The implementation of com‐bined C-PR, mAlb, and HbA1c assay in DN patients has high diagnostic value and facilitate patients to get effective treatment as early as possible.[Key words] Serum C peptide; Urine microalbumin; Glycated hemoglobin; Diabetic nephropathy; Diabetes mellitus糖尿病(diabetes mellitus, DM)作为我国较为常见的一种慢性代谢性疾病,据流行病学调查显示,我国每11个人里面就有1例糖尿病,患病率高达30.2%,且近年来随着人们生活方式及饮食习惯的改变,患病率呈现出逐年递增趋势,引起了社会各界的广泛重视。

基于人工智能的冠状动脉易损斑块腔内影像学研究进展

基于人工智能的冠状动脉易损斑块腔内影像学研究进展陈远兴综述韩韦钰,赵然尊审校遵义医科大学附属医院心血管内科,贵州遵义563000【摘要】斑块的不稳定导致冠状动脉的血栓性闭塞是大多数急性冠脉综合征(ACS)的原因。
尽管罪犯血管得以及时开通,但非罪犯血管的易损斑块对患者远期预后仍存在较大威胁。
因此,动态评估易损斑块的变化,对冠心病患者格外重要。
冠状动脉血管腔内成像技术,如血管内超声(IVUS)、光学相干断层扫描(OCT)、近红外光谱(NIRS)以及其多模态融合技术等,因其可视化、准确度高,可以揭示易损斑块的不同特征,常用于检测易损斑块。
而IVUS 、OCT 等图像解释需有经验的心血管临床医生逐帧判断,需要大量的时间成本,且图像的解读存在的观察者内及观察者间的差异,这推动了人工智能(AI)在冠状动脉血管腔内影像学应用的发展。
由于电子医疗系统的广泛应用、临床大数据的日益暴增,AI 已在医疗行业获得了极大的进展。
人工智能结合腔内影像学在斑块的识别、干预、预后等诸多方面广泛应用,未来将不断优化诊疗系统,提高精准医疗水平,实现对易损斑块的早期诊断及合理干预。

The number of patients is increasing year by year, and the economic cost of nursing is high, which poses a major challenge to the global economy. In recent years, studies have shown that probiotics, as microorganisms beneficial to the health of the host, have a positive impact on the prevention and treatment of Alzheimer’s disease. Its mechanism may be through regulating intestinal flora, affecting the nervous immune system, regulating the neuroactive substances and metabolites, and affecting the occurrence and development of the disease through thegut- brain axis. This paper reviews the progress of probiotics on Alzheimer’s disease at home and abroad in recent years, as well as its potential mechanism of prevention and treatment.Key words:probiotics; Alzheimer’s disease; gut microbiota; mechanism阿尔茨海默病(Alzheimer’s disease, AD),系中枢神经系统退行性疾病,属于老年期痴呆常见类型,临床特征主要包括:记忆力减退、认知功能障碍、行为改变、焦虑和抑郁等。
