The relationships among monocyte subsets,miRNAs and inflammatory cytokines in patients with acute myocardial infarction

Background

Acute myocardial infarction (AMI) causes irreversible myocardial damage and release of inflammatory mediators, including cytokines, chemokines and miRNAs. We aimed to investigate changes in the levels of cytokines (IL-6, TNF-α and IL-10), miRNAs profiles (miR-146 and miR-155) and distribution of different monocyte subsets (CD14++CD16-, CD14++CD16+, CD14+CD16++) in the acute and post-healing phases of AMI.

Influenza vaccination and the endurance against air pollution among elderly with acute coronary syndrome

ObjectiveAir pollution, weather condition and influenza are known risk factors of acute coronary syndrome (ACS) among elderly people. The influenza vaccine (IV) has been shown to reduce major cardiovascular events. The purpose of this study was to compare resistance to air pollution and weather factors causing ACS between vaccinated and less-vaccinated elderly people.MethodsA case–crossover design was applied to 1835 elderly ACS patients who were obtained from the 1-million sample of Taiwan National Health Insurance Research Data with inclusion criteria: (1) the first diagnosis of ACS was in cold season and at age 68 or more, (2) had received the free IV program at least once during the period 3 years before the ACS. They were stratified into two groups: 707 had received flu vaccinations for all the 3 years and the remaining 1128 had not. The measurements of air pollutants, temperature, and humidity corresponding to each of the 3 days prior to the ACS diagnosis date were retrieved from the data banks of the Taiwan Environmental Protection Administration and Central Weather Bureau.FindingsIncreases in air pollution concentrations of CO, NO₂, PM₁₀ or PM_2.5 and decreases in temperature significantly influenced the risk of ACS for the non-continuously vaccinated elderly population; however, less significant effects were observed for the continuously vaccinated population.ConclusionConsecutive influenza vaccination may potentially offer resistance against the detrimental effects of air pollution and changes in temperature in frail elderly adults with ACS. Future studies are needed to directly assess the interaction effect between the vaccination and environmental factors on ACS.     

Acute liver injury,acute liver failure and acute on chronic liver failure: A clinical spectrum of poisoning due to Gyromitra esculenta

Gyromitra esculenta, also known as “false morel” is one of the most poisonous mushrooms. This species is found all over the world, growing in coniferous forest in early spring time. Common manifestation of poisoning includes gastrointestinal symptoms which include varied degrees of liver impairment.We describe three cases: acute liver injury, acute liver failure and acute-on-chronic liver failure due to G. esculenta poisoning. At admission patients presented with encephalopathy and features of liver failure. Two of them recovered completely following supportive management while the remaining patient who also had preexisting liver disease developed multiorgan failure and subsequently died.Although a rare occurrence, G. esculenta poisoning should be considered in the differential diagnosis of acute liver failure.     

A new era of immuno-oncology in acute myeloid leukemia - antibody-based therapies and immune checkpoint inhibition

Acute myeloid leukemia (AML) remains a therapeutically challenging malignancy with high rate of relapse and poor outcomes. There has been increased understanding of the molecular characteristics of AML and the various roles of the immune system in its pathogenesis, the result of which has led to the study and development of multiple immune-based approaches for this disease. In this review, we aim to provide an overview of the recent advancements made in antibody-based approaches to the treatment of AML including monoclonal antibodies, antibody-drug conjugates, and immune checkpoint inhibition. In addition, we provide insight and discuss the promise of these agents, some of which may soon enter the therapeutic armamentarium we currently employ against this lethal disease.     

清热化瘀汤对急性脑出血患者血清hs-CRP、血浆S100β蛋白和NSE的影响

目的:探究清热化瘀汤联合依达拉奉对急性脑出血患者血清超敏C反应蛋白(hs-CRP)、血浆S100β蛋白和神经元特异性烯醇化酶(NSE)的影响。方法:选择2017年5月—2019年5月在我院神经内科就诊符合纳入标准的80例急性脑出血患者,随机分为联合组(40例)和依达拉奉组(40例),两组均给予基础治疗和依达拉奉静脉滴注治疗,联合组则在此基础上加用清热化瘀汤。观察并比较两组的临床疗效、神经功能缺损程度评分(NIHSS)、格拉斯哥昏迷评分(GCS)、hs-CRP、S100β蛋白和NSE水平及脑血肿量。结果:联合组的总有效率为95%(38/40),显著高于依达拉奉组的总有效率75%(30/40)(P<0.05)。治疗后,两组NIHSS评分降低,GCS评分升高,且联合组NIHSS评分明显低于依达拉奉组(P<0.05),GCS评分高于依达拉奉组(P<0.05)。治疗后,两组hs-CRP、S100β蛋白和NSE水平及均脑血肿量均低于治疗前,且联合组hs-CRP、S100β蛋白和NSE水平及脑血肿量明显低于依达拉奉组(P<0.05)。结论:清热化瘀汤联合依达拉奉对急性脑出血患者具有良好的疗效,可显著改善其神经缺损,降低hs-CRP、S100β蛋白和NSE水平及脑血肿量。     

SWIM技术治疗后循环大血管闭塞所致急性缺血性卒中的有效性和安全性观察

目的 观察SWIM技术治疗后循环大血管闭塞所致急性缺血性卒中的有效性及安全性。 方法 回顾性分析2017年2月-2018年11月于大连市中心医院采用SWIM技术治疗的后循环大血管闭 塞所致急性缺血性卒中患者的临床资料，评价该技术的疗效和安全性，并分析影响患者预后的因素。 观察指标为术后即刻成功再通（mTICI≥2b）、90 d良好预后（mRS评分≤2分），以及术后24 h任何颅内 出血、90 d全因死亡。 结果 共纳入35例患者，平均年龄66.1±12.1岁，男性26例（74.3%），基线NIHSS评分22（15～34）分。 术后即刻成功再通率为94.3%（33/35），90 d良好预后率为45.7%（16/35），24 h颅内出血率为17.1% （6/35），90 d全因死亡率为37.1%（13/35）。单因素分析显示，基线NIHSS评分较低（P =0.001）、基 线后循环ASPECTS评分较高（P =0.016）、发病至到院时间较短（P =0.039）、发病至再通时间较短 （P =0.047）、血管成功再通率较高（P =0.036）以及饮酒比例较低（P =0.042）与良好预后相关。 结论 使用SWIM技术治疗后循环急性缺血性卒中相对安全、有效。
