尿酸性肾病中医分型与氧化应激指标的相关性研究

目的：探讨尿酸性肾病中医分型与氧化应激相关性。方法：采用回顾性分析方法对2017年12月至2019年9月北京中医药大学第三附属医院收治的尿酸性肾病患者105例进行研究，选择同时期正常健康者105例作为对照，参考《中药新药临床研究指导原则》将105例尿酸性肾病和临床常见证型相结合，分成脾肾气虚18例、气阴两虚证19例、肝肾阴虚16例、阴阳两虚12例、湿热蕴结19例、瘀血阻滞17例、痰浊内阻13例，均在入院次日清晨空腹抽取静脉血，检测氧化应激氧化应激、肾功能损害指标，比较不同组别在氧化应激指标含量水平变化情况，比较中医分型和氧化应激、肾功能损害指标水平变化。结果：1）尿酸性肾病组总抗氧化能力（T-ACO）、晚期蛋白氧化物（AOPP）、血清丙二醇（MDA）、超氧化物歧化酶（SOD）含量水平分别为（19.45±3.42）U/mL、（42.45±3.53）μmol/L、（4.52±1.23）nmol/L、（76.78±5.64）U/mL，正常对照组则分别为（10.76±1.31）U/mL、（20.84±1.28）μmol/L、（2.13±0.76）nmol/L、（130.85±16.75）U/mL，尿酸性肾病组T-ACO、AOPP、MDA较正常对照组显著偏高，SOD显著偏低（P<0.05）。2）虚证中阴阳两虚证SOD含量上较其他证型均偏低，而MDA、T-AOC、AOPP、胱抑素C（CysC）、β2微球蛋白、尿微量白蛋白（UMALB）、蛋白尿发生率则较其他证型均偏高，差异均有统计学意义（P<0.05），实证中瘀血阻滞证SOD含量较其他证型均偏低，而MDA、T-AOC、AOPP则较其他证型均偏高，差异均有统计学意义（P<0.05）。结论：尿酸性肾病中医分型的阴阳两虚证、瘀血阻滞证氧化应激水平、肾损害指标均显著升高，可结合该实验室检查进行临床干预。     

Total Knee Arthroplasty Is Safe and Successful in Patients With Klippel-Trénaunay Syndrome

Background

Klippel-Trénaunay syndrome (KTS) is a severe vascular malformation that can lead to hypertrophic osteoarthritis. Total knee arthroplasty (TKA) performed in extremities affected with KTS is challenging given the high-risk vascular considerations and occasionally poor bone quality.

Association between long-term exposure of ambient air pollutants and cardiometabolic diseases: A 2012 Korean Community Health Survey

Background and aim

The associations of long-term exposure to particulate matter <10 μm in size (PM₁₀), nitrogen dioxide (NO₂), carbon monoxide (CO), sulfur dioxide (SO₂), and ozone (O₃) with cardiometabolic diseases (CMD) remain uncertain in the Korean population. Therefore, we sought to examine the associations between PM₁₀, NO₂, CO, SO₂, and O₃ and CMD using data collected from the Korean Community Health Survey.

Seizure as the Presenting Symptom for Atypical Hemolytic Uremic Syndrome

Background

Atypical hemolytic uremic syndrome (aHUS) is a complement-mediated disease manifesting in thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney injury. It has a higher incidence of extrarenal manifestations, including central nervous system findings like seizure or stroke, pancreatitis, and cardiac manifestations.

Cerebrovascular events during pregnancy and puerperium

Though cerebrovascular complications of pregnancy remain relatively rare, they represent a potentially devastating event that necessitates prompt identification and treatment. Eighteen percent of strokes occurring in young women are linked to pregnancy. They occur mostly in the third trimester or during the post-partum period. Their biggest risk factors are hypertension, preeclampsia/eclampsia and migraine. Cerebrovascular events occurring during this period may involve specific pathophysiological processes that include embolic phenomena or endothelial dysfunction, but can also have common etiologies that are simply favored by the context of pregnancy. Thus, posterior encephalopathy and vasoconstriction cerebral syndrome are relatively frequently involved in cerebrovascular complications of pregnancy. Other very specific causes like amniotic fluid embolism or postpartum cardiomyopathy can also be responsible for such events. The management of stroke during pregnancy must be multidisciplinary and include a neurovascular expertise. Some conditions can lead to a long-life follow-up and modify the management of a future pregnancy.     

Clearing hepatitis C virus with direct antiviral agents reduces cardiovascular events in patients with prediabetes. Commentary to Sasso and colleagues

Liver health is a key determinant of cardiovascular risk (CVR). Hepatic fibrosis is the shared common result of chronic hepatitis, irrespective of aetiology. Fibrosis profoundly distorts liver tissue architecture and perturbs hepatic physiology, dictates the course of chronic liver disease and is increasingly recognized as a CVR factor. The relative weights of pre-diabetes and hepatic fibrosis as risk factors for major adverse cardiac events (MACE) in patients with HCV remain an open issue. Sasso and Colleagues answered this research question by treating approximately half of 770 HCV positive pre-diabetic patients with direct antiviral agents (DAAs), while the rest served as historical controls. Data have shown that achieving HCV clearance with DAAs was associated with a 60% reduced risk of MACE, thereby implying that this antiviral strategy is recommended in HCV positive pre-diabetic patients, regardless of the severity of liver disease and concurrent CVR factors. This study paves the way for additional studies addressing the molecular patho-mechanisms and changes in the clinical spectrum involved in cardio-metabolic protection following HCV eradication in patients with pre-diabetes.     

Associations of metabolically healthy obesity with prevalence and progression of coronary artery calcification: Results from the Heinz Nixdorf Recall Cohort Study

Background and aims

There is controversy on the potentially benign nature of metabolically healthy obesity (MHO), i.e., obese persons with few or no metabolic abnormalities. So far, associations between MHO and coronary artery calcification (CAC), a measure of subclinical atherosclerosis, have mainly been studied cross-sectionally in Asian populations. We assessed cross-sectional and longitudinal MHO CAC associations in a Caucasian population.

Multicenter Study of the Psychometric Properties of the New Demoralization Scale (DS-II) in Spanish-Speaking Advanced Cancer Patients

Context

Demoralization is a state of existential distress in patients with advanced illness, typically with coping difficulties, feelings of loss of sense, and purpose in life and despair, among other things. The New Demoralization Scale (DS-II) is an evaluation tool for this syndrome, which has recently been reformulated on a shorter scale.

Circulating CCL20: A potential biomarker for active vitiligo together with the number of Th1/17 cells

Background

Vitiligo is an autoimmune disease with varying pathological features. Activation of the CCL20-CCR6 axis plays an important role in chronic inflammatory diseases. However, whether CCL20-CCR6 and Th1/17 cells are indicative of active vitiligo is unclear.
