目的 探讨生物电抗无创心排监测（bioreactance noninvasive cardiac output monitoring,NICOM）心指数（cardiac index,CI）和总外周阻力指数（total peripheral resistance index TPRI）对呼吸困难病因诊断的临床价值。方法 采用前瞻性观察性研究的方法 ,纳入急性呼吸困难或慢性呼吸困难急性加重的患者共113例,临床医师根据2010年中华医学会心血管病学分会编委会组织编写的《急性心力衰竭诊断和治疗指南》为金标准分为心力衰竭组（n=55）和非心力衰竭组（n=58）,通过NICOM监测CI、TPRI,构建受试者工作特征曲线（receiver operating characteristic curve,ROC曲线）,分析CI和TPRI对心力衰竭的诊断价值。结果 心力衰竭组患者的CI低于非心力衰竭组（P<0.001）;心力衰竭组患者TPRI高于非心力衰竭组（P<0.001）;利用ROC曲线进行分析,CI曲线下面积（area under the curve,AUC）为0.792（95%CI：0.708~0.875,P=0.000）,当CI截断值取2.65L/（min·m²）时,诊断心力衰竭的敏感度为63.6%,特异度为87.9%;TPRI的AUC为0.733（95%CI：0.641~0.825,P=0.000）,当TPRI截断值取2 353dynes.sec/（cm⁵·m²）时,诊断心力衰竭的敏感度为72.7%,特异度为67.2%;CI联合TPRI诊断心力衰竭的敏感度为80%,特异度为65.5%。结论 NICOM监测CI对心力衰竭所致的呼吸困难特异度高,联合TPRI监测可提高敏感度。

Objective To investigate the clinical values of etiological diagnosis by testing cardiac index CI and total peripheral resistance index TPRI using bioreactance noninvasive cardiac output monitoring NICOM in patients with dyspnea. Methods Prospective,observational study was taken in 113 adult patients admitted with dyspnea or acute exacerbation of dyspnea in stable disease. The patients were divided into two groups namely heart failure group （n=55）and non-heart failure group（n=58） according to the guidelines on the diagnosis and treatment of acute heart failure（2010） as the standard criterion. All patients underwent CI and TPRI test by using NICOM. Receiver operating characteristic curve（ROC curve） was plotted to evaluate the diagnostic value of CI and TPRI. Results Compared with non-heart failure group,the CI was worse（P<0.001）,and the TPRI was elevated（P<0.001）. ROC curve showed that the area under the curve（AUC） of CI was 0.792（95%CI：0.708~0.875,P=0.000）. The cut-off of CI was 2.65L/min/m²,the sensitivity was 63.6%,and specificity was 87.9%. The AUC of TPRI was 0.733（95%CI：0.641~0.825,P=0.000）. The cut-off of CI was 2 353dynes.sec/cm⁵/m²,the sensitivity was 72.7%,and specificity was 67.2%. The sensitivity of CI combined TPRI was 80%,and specificity was 65.5%. Conclusion NICOM monitoring CI have high specificity,and combined TPRI monitored may improve sensitivity for dyspnea caused by heart failure.

Objective To explore the relationship between different type of Type 2 diabetes nephropathy and chemerin,SOD,MDA. Methods A total of 100 inpatients and outpatients were enrolled in this study between January 2016 and December 2017 in Guangzhou First People's Hospital. They were divided into normal urinary protein group (NA group, n=33), microalbuminuria group (MA group, n=34) and massive proteinuria group (CA group, n=33) based on ACR. Another 32 healthy people were collected as a control group in medical examination center (NC group, n=32). The levels of blood sugar, glycated hemoglobin, serum creatinine, ACR, 24-hour urinary protein, cholesterol, triglyceride, SOD, MDA and chemerin were measured. Results The level of SOD: NC group > NA group > MA group > CA group (P< 0.05). The level of MDA: CA group > MA group > NA group > NC group (P< 0.05). The level of chemerin: CA group > MA group > NA group > NC group (P< 0.05). Correlation analysis showed that ACR was negatively correlated with serum SOD and positively correlated with MDA and chemerin. Multivariate logistic regression demonstrated that course of disease, CHOL, HbA1c and chemerin were the main factors affecting ACR. Conclusion Chemerin, MDA and SOD may be involved in the occurrence and development of diabetic nephropathy. Chemerin, MDA and SOD may reflect the severity of type 2 diabetic nephropathy
