The ratio of superior mesenteric artery diameter to superior mesenteric vein diameter based on non-enhanced computed tomography in the early diagnosis of spontaneous isolated superior mesenteric artery dissection.

Background: Spontaneous isolated superior mesenteric artery (SMA) dissection (SISMAD) is a rare cause of abdominal pain. The aim of the study is to investigate the role of a new parameter, the ratio of the SMA diameter to the superior mesenteric vein (SMV) diameter (SMA/SMV) based on non-enhanced computed tomography (CT), in the early diagnosis of SISMAD.

Methods: In a registry study from December 2013 to June 2021, 97 abdominal pain SISMAD patients (SISMAD group) admitted to our hospital were enrolled.

Clinical characteristics and misdiagnosis of spontaneous isolated superior mesenteric artery dissection.

Background: Spontaneous isolated superior mesenteric artery (SMA) dissection (SISMAD) is a rare disease with a potentially fatal pathology. Due to the lack of specificity of clinical characteristics and laboratory tests, misdiagnosis and missed diagnosis are often reported. Therefore, the aim of this study was to investigate the clinical characteristics and misdiagnosis of SISMAD.

Role of electrocardiograms in assessment of severity and analysis of the characteristics of ST elevation in acute myocarditis: A two-centre study.

Acute myocarditis is a severe disease with a high mortality rate and various dynamic changes visible on electrocardiograms (ECGs). The purpose of the present study was to investigate ECG findings of patients with acute myocarditis, ECG findings associated with fulminant myocarditis (FM) and the characteristics of ST elevation on admission. A retrospective analysis of 1,814 ECGs of 274 consecutive patients with acute myocarditis aged ≥13 years, who were hospitalized in two centres between August 2007 and November 2019, was performed.

Type A aortic dissection in pregnant patients with fibrillin-1 gene mutations: Two case reports and a literature review.

In acute aortic dissection (AD) in pregnancy, increased cardiovascular stress due to pregnancy is an important factor leading to an emergent aortic event. It is rare but often results in a devastating event for both the pregnant patient and the foetus. Two cases of acute AD (Stanford type A) in pregnant females are presented in the present study.

N,N-dimethylformamide-induced acute hepatic failure: A case report and literature review.

N,N-dimethylformamide (DMF) is a major solvent predominantly used in the chemical industry. The main toxic effects following exposure to DMF are gastric irritation, skin eruption and hepatotoxicity. However, hepatic failure induced by DMF is rare.

Advances in clinical studies of cardiopulmonary resuscitation.

Background: The survival rate of patients after cardiac arrest (CA) remains lower since 2010 International Consensus on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC) was published. In clinical trials, the methods and techniques for CPR have been overly described. This article gives an overview of the progress in methods and techniques for CPR in the past years.

Factors influencing outcomes after cardiopulmonary resuscitation in emergency department.

Background: The outcome of cardiopulmonary resuscitation (CPR) may depend on a variety of factors related to patient status or resuscitation management. To evaluate the factors influencing the outcome of CPR after cardiac arrest (CA) will be conducive to improve the effectiveness of resuscitation. Therefore, a study was designed to assess these factors in the emergency department (ED) of a city hospital.

Rapid detection of recurrent intraventricular hemorrhage by ultrasound in a multiple trauma patient who had undergone craniectomy.

Ultrasound may be a useful tool to evaluate intracranial abnormalities in critically ill patients undergoing decompressive craniectomy. We present a multiple trauma patient who had undergone craniectomy and in whom recurrent intraventricular hemorrhage and patterns of cerebral blood flow were rapidly detected by ultrasound.

Effect of exogenous phosphocreatine on cardiomycytic apoptosis and expression of Bcl-2 and Bax after cardiopulmonary resuscitation in rats.

Background: Ischemia-reperfusion injury in the myocardium after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) is an important pathologic basis of post-cardiac arrest of syndrome (PCAS), and apoptosis is one of the major mechanisms in myocardial ischemia-reperfusion injury. To lessen myocardial ischemia-reperfusion injury after cardiac arrest and CPR, it is important to reduce energy consumption and to increase energy supply in the myocardium. This study aimed to observe changes of cell apoptosis and expression of Bcl-2 and Bax protein on the myocardium after CPR in rats, and the protective effects of different doses of exogenous phosphocreatine (creatine phosphate, CP) on them.

Effects of Hemin on neuroglobin expression after cardiopulmonary resuscitation in rats.

Background: Despite a large amount of resuscitation research, the survival rate after cardiac arrest remains low, and brain injury is the key issue. Neuroglobin (NGB) is an oxygen-binding heme protein found in the brain with a protection role against ischemic-hypoxic brain injury. Hemin is an effective activator of neuroglobin.

[Protective effect of ulinastatin on myocardium after cardiopulmonary resuscitation in rats].

Objective: To investigate the changes in serum creatine kinase isoenzyme (CK-MB) and cardiac troponin I (cTnI) levels and the ultrastructure of myocardium, and the effect of ulinastatin after cardiopulmonary resuscitation (CPR) in rats.

Methods: One hundred and twenty Sprague-Dawley (SD) rats were randomly divided into sham operation group, CPR group and ulinastatin group. And each group was divided into five subgroups (n=8) according to time points of 0.

[Expression of mRNA of matrix metalloproteinase and tissue inhibitor of matrix metalloproteinase after cardiopulmonary resuscitation for asphyxial cardiac arrest in rat].

Objective: To study the change in mRNA expression of matrix metalloproteinase (MMPs) and tissue inhibitor-1 of matrix metalloproteinase (TIMP-1) in brain after cardiopulmonary resuscitation (CPR) for asphyxial cardiac arrest in rat.

Methods: The animal model of cardiac arrest was reproduced by clamping endotracheal tube at the expiration. Eighty male SD rats were randomly divided into two groups: control group and resuscitation group, and they were again divided into 0, 0.

Changes of tumor necrosis factor-alpha and the effects of ulinastatin injection during cardiopulmonary cerebral resuscitation.

The changes of tumor necrosis factor-alpha (TNF-alpha) and brain ultrastructure during cardiopulmonary resuscitation and the effects of ulinastation injection were observed, and the mechanism was investigated. Twenty-four adult healthy Sprague-Dawley rats were randomly divided into control group (8 rats), resuscitation group (8 rats) and ulinastatin (UTI) group (8 rats). Rats in control group underwent tracheotomy without clipping the trachea to induce circulatory and respiratory standstill.
