Association between hemoglobin glycation index and subclinical myocardial injury in the general population free from cardiovascular disease

Background and aimsThe relationship between hemoglobin glycation index (HGI) and the diagnosis and prognosis of cardiovascular disease (CVD) has been verified by previous studies. However, it remains unknown whether HGI has a predictive effect on subclinical myocardial injury (SC–MI). The purpose of the present study was to explore the relationship between HGI and SC–MI in the general population free from CVD.Methods and resultsThe present study included 6009 participants free of CVD from the third National Health and Nutrition Examination Survey. Binary Logistic regression analysis was used to tested the association between HGI and SC–MI. As results, the HGI was significantly higher in participants with SC–MI compared with those without, and the HGI was positively correlated with SC–MI and other metabolic disorder parameters. Each 1-unit increase of HGI and glycated hemoglobin A1c (HbA1c) was independently associated with higher risk of SC–MI (P < 0.05), while fasting plasma glucose (FPG) was no longer a predictive indicator of SC–MI with the increase of confounding factors [OR (95% CI): 1.001 (0.999–1.003), P = 0.305]. And in the subgroup analysis, HGI, only in participants without diabetes, was independently associated with higher risk of SC–MI, while HbA1c and FPG had no independent predictive role in both diabetic and non-diabetic participants.ConclusionsHGI was a significant predictor of SC–MI in the general population free from CVD.     

基于一项“多中心、随机对照、双盲”的临床研究探讨影响肾功能进展的因素＊

目的 基于一项前瞻性、多中心、随机、安慰剂对照、双盲的临床试验结果，探索影响肾功能进展的因素。方法 选择343例慢性肾脏病3期的患者，将入组的患者随机分为治疗组和对照组，治疗组给予中药颗粒剂口服，对照组给予安慰剂口服。两组患者均给予基础治疗，疗程24周。评估两组患者肾功能变化情况。治疗结束后，根据患者肾功能情况，以CKD3期为界限，将病情好转者定为A组，该组患者血肌酐下降至CKD2期或CKD1期；病情恶化者为B组，该组患者血肌酐上升至CKD4期或CKD5期；病情稳定者为C组，该组患者血肌酐稳定，仍处于CKD3期，分析各组患者指标的差异。结果 经过24周观察，比较两组患者的血肌酐（Scr）水平，治疗组130.78 ± 32.55 μmol·L^-1，对照组149.12 ± 41.27 μmol·L^-1，两组比较，差异有统计学意义（P < 0.05）。eGFR水平比较，治疗组55.74 ± 50.82 mL/min/1.73 m²，对照组44.46 ± 12.60 mL/min/1.73 m²，差异有统计学意义（P < 0.05）。研究结束后，A组患者血尿酸水平明显低于B组和C组的患者，A组患者血红蛋白水平明显高于B组和C组的患者，A组患者的血磷水平明显低于B组和C组的患者。结论 中药颗粒剂在24周内可以明显改善肾功能，患者的血尿酸水平、血红蛋白及血磷水平对肾功能有一定的影响。

目的:探讨加味十全大补汤对老年股骨粗隆间骨折患者术后隐性失血及血糖水平的影响。方法:选取120例老年股骨粗隆间骨折患者,随机分为两组,各60例。两组均行防旋型股骨近端髓内钉(PFNA),对照组术前不予以药物治疗,观察组术前3 d予以加味十全大补汤。统计两组住院时间、骨折愈合时间,对比术前、术后1 d、3 d、7 d血红蛋白(Hb)、红细胞比容(Hct)水平、隐性失血量、空腹血糖水平,并于术后6个月随访,观察髋关节恢复情况。结果:术后1 d、3 d、7 d,观察组Hb、Hct水平高于对照组(P<0.05)。观察组术后1～3 d、3～7 d隐性失血量分别为(245.74±88.26)ml、(188.26±70.12)ml,均少于对照组(288.67±90.94)ml、(245.94±75.36)ml(P<0.05)。术后1 d、3 d、7 d,观察组空腹血糖水平分别为(7.74±0.76)mmol/L、(6.26±0.52)mmol/L、(5.12±0.46)mmol/L均低于对照组(9.67±0.84)mmol/L、(7.94±0.66)mmol/L、(6.48±0.52)mmol/L(P<0.05)。观察组骨折愈合时间、住院时间短于对照组(P<0.05)。术后6个月随访,观察组髋关节功能恢复优良率91.38%与对照组84.21%,组间比较差异无统计学意义(P>0.05)。结论:加味十全大补汤治疗老年股骨粗隆间骨折患者,可纠正贫血,减少隐性失血量,加快骨折愈合,缩短住院时间,且对血糖水平影响较小。     

妊娠早期糖化血红蛋白联合PAPP-A对妊娠期糖尿病的预测意义

目的:探讨妊娠早期血清学指标糖化血红蛋白(glycohemoglobin,HbA1c)联合妊娠相关血浆蛋白A(pregnancy-associated plasma protein A,PAPP-A)对妊娠期糖尿病(gestational diabetes mellitus,GDM)的预测意义。方法:随机选取2018年12月1日-2019年7月30日孕11~13+6周于我院门诊产检的妊娠妇女,进行临床资料采集并记录妊娠早期(11~13+6周)空腹血糖(fasting plasma glucose,FPG)、HbA1c、PAPP-A中位数倍数(multiple of the median,MoM)水平,根据孕24~28周进行的75 g口服葡萄糖耐量试验(oral glucose tolerance test,OGTT)结果将研究对象分为研究组和对照组,统计分析妊娠早期血清学指标预测GDM的最佳截断值并得出最适宜的联合预测方案。结果:多因素Logistic回归分析显示,高水平FPG和HbA1c、低水平PAPP-A、受孕方式采用辅助生殖技术、有家族糖尿病史以及妊娠早期体质量指数(BMI)为超重或肥胖均是GDM发生的独立危险因素。有糖尿病家族史和使用辅助生殖技术受孕发生GDM的风险显著增高(OR分别为7.206和47.512,均P<0.001)。分析不同预测指标的受试者工作特征(receiver operating characteristic,ROC)曲线及曲线下面积(area under the curve,AUC)显示,PAPP-A MoM联合HbA1c及FPG诊断时AUC最大(0.728),其后依次为PAPPA MoM联合HbA1c(0.721)、HbA1c联合FPG(0.717),均大于HbA1c(0.707)和FPG(0.647),而PAPP-A MoM的AUC为0.380,对GDM没有诊断意义。结论:具有高风险因素的孕妇,推荐在妊娠早期联合检测HbA1c与PAPPA MoM,以早期预测GDM。     

Detecting Optic Atrophy in Multiple Sclerosis Patients Using New Colorimetric Analysis Software: From Idea to Application

Neuro-ophthalmologists typically observe a temporal pallor of the optic disc in patients with multiple sclerosis. Here, we describe the emergence of an idea to quantify these optic disc color changes in multiple sclerosis patients. We recruited 12 multiple sclerosis patients with previous optic neuritis attack and obtained photographs of their optic discs. The Laguna ONhE, a new colorimetric software using hemoglobin as the reference pigment in the papilla, was used for the analysis. The papilla of these multiple sclerosis patients showed greater pallor, especially in the temporal sector. The software detected the pallor and assigned hemoglobin percentages below normal reference values. Measurements of optic disc hemoglobin levels obtained with the Laguna ONhE software program had good ability to detect optic atrophy and, consequently, axonal loss in multiple sclerosis patients. This new technology is easy to implement in routine clinical practice.
