Introduction: Accurate image segmentation is crucial in medical imaging for quantifying diseases, assessing prognosis, and evaluating treatment outcomes. However, existing methods often fall short in integrating global and local features in a meaningful way, failing to give sufficient attention to abnormal regions and boundary details in medical images. These limitations hinder the effectiveness of segmentation techniques in clinical settings.

Accurate medical image segmentation is critical for disease quantification and treatment evaluation. While traditional U-Net architectures and their transformer-integrated variants excel in automated segmentation tasks. Existing models also struggle with parameter efficiency and computational complexity, often due to the extensive use of Transformers.

Background: Alcoholic liver disease (ALD) is exacerbated by disruptions in intestinal microecology and immune imbalances within the gut-liver axis. The present study assesses the therapeutic potential of combining () with inosine in alleviating alcohol-induced liver injury.

Methods: Male C57BL/6 mice, subjected to a Lieber-DeCarli diet with 5% alcohol for 4 weeks, served as the alcoholic liver injury model.

Background: The aim of this study was to identify key immune-related genes in acute liver failure (ALF) by constructing an ALF mouse model for transcriptome sequencing.

Methods: The C57BL/6 mouse with ALF model was induced by lipopolysaccharide (LPS)/ D-galactosamine (D-GalN). After successful modelling, the liver tissues of all mice were obtained for transcriptome sequencing.

Objective: Intracoronary ECG (IC-ECG) recording has been shown to be sensitive and reliable for detecting myocardial viability and local myocardial ischaemia in some studies. But IC-ECG is neither widely used during percutaneous coronary intervention (PCI) nor recommended in guidelines. This up-to-date meta-analysis of published studies was conducted to evaluate the prognostic and diagnostic accuracy of IC-ECG recorded during PCI.

Background: While great attention has been paid to motor and cognitive impairments in children with neonatal Hypoxic-Ischemic Encephalopathy (HIE), sleep related circadian rhythm problems, although commonly present, are often neglected. Subsequently, no early clinical indicators have been reported to correlate with sleep-related circadian dysfunction during development.

Methods: In this study, we first analyzed patterns of the amplitude integrated electroencephalogram (aEEG) in a cohort of newborns with various degrees of HIE.

Background: Lethal neonatal rigidity and multifocal seizure syndrome (RMFSL) is caused by variants in BRAT1 (BRCA1-associated protein required for ATM activation-1). However, the molecular mechanism of RMFSL is still unclear.

Methods: An RMFSL infant was recruited and the peripheral blood samples from his trio-family were collected.

Exercise training (ET) could improve myocardial infarction (MI), and microRNA-497 is highly associated with MI. This study aimed to investigate whether the regulation of miR-497 is involved in the positive effects of ET on MI. MI rat models induced by left anterior descending (LAD) were subjected to interval training and infarct size was observed.

Background: The exact relationship between serum myostatin and the severity and prognosis of chronic heart failure (CHF) is unclear. In this study, we investigated the association between serum myostatin and the severity and prognosis in patients with CHF.

Methods: Two hundred and eighty-eight CHF patients and 62 healthy controls were studied.

Background: Peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α) plays key roles in controlling cardiac metabolism and function. Myocardial energy expenditure (MEE) can reflect myocardial energy metabolism and cardiac function. Whether the variation of PGC-1α can influence MEE levels in chronic heart failure (CHF) is unclear.

Background: Cardiovascular benefits by reversing environmental risks factors for essential hypertension (EH) and dyslipidemia could be weaken by high genetic risk. We investigated possible associations between ACE2 polymorphisms and dyslipidemia in patients with EH.

Methods: Four hundred and two hypertensive patients were enrolled in an EH group and 233 normotensive individuals were enrolled as control group from the Xinjiang region of China.

To observe the clinical efficacy and safety of topical ozone therapy for patients with herpes zoster by reflectance confocal microscopy (RCM).
 Methods: A total of 60 patients with herpes zoster were divided into a control group and an ozone treatment group (n=30). In the control group, patients took oral valacyclovir tablets or granules (0.

To evaluate the clinical efficacy and safety of the innovative topical ozone therapy for infantile atopic dermatitis.
 Methods: Sixty children with atopic dermatitis were divided into a treatment group and a control group. The treatment group was showered with ozonated water (3-5 times a week) and smeared with ozonated oil (twice a day), while the control group was washed with warm running water and smeared with base oil, adding moisturizer if necessary.

Article Synopsis
  • The study measures initial concentrations of ozonated water at various temperatures (20 to 40 ℃) and assesses how these concentrations affect the water's ability to kill common microorganisms.
  • Initial ozonated water concentrations drop with increasing temperature, from 4.38 mg/L at 20 ℃ to 1.31 mg/L at 40 ℃, with rapid attenuation observed in the first 10 minutes.
  • Ozonated water at concentrations of 1.0 mg/L and 0.3 mg/L shows high killing rates (up to 100%) against several microorganisms, indicating its effective sterilization ability, especially at 20-30 ℃.

Background: Myocardial ischemia-reperfusion injury (MIRI) resulting from primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) is considered harmful to the patient, but its clinical significance remains unclear. This study explored the relationship of cardiac function examined by echocardiography and serum creatine kinase (CK) and CK-MB levels with MIRI in a cohort of Chinese AMI patients.

Material/methods: We retrospectively analysed the clinical and angiographic data in 228 AMI patients in whom the infarct-related artery (IRA) was successfully recanalized by primary PCI.

Background: The poor clinical outcome in acute myocardial infarction (AMI) patients undergoing primary percutaneous coronary intervention (PCI) has been attributed to myocardial ischemia-reperfusion injury (MIRI).

Objective: This study aimed to identify the predictive factors of MIRI during PCI in Chinese AMI patients with or without ST-segment elevation.

Methods: Clinical and angiographic data of 228 patients in whom the infarct-related artery (IRA) was successfully recanalized by primary PCI were retrospectively analyzed.

Objective: To investigate the clinical implications of reperfusion arrhythmias during primary percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (AMI).

Methods: Data from 228 AMI patients in whom the infarct-related artery (IRA) were successfully recanalized by primary PCI were retrospectively analyzed. The 228 patients were divided into 2 groups: myocardial ischemia-reperfusion injury (MIRI) group (n=119) in whom MIRI events occurred within minutes after successful recanalization of IRA, and non-MIRI group (n=109).

Objective: To explore the risk and protective factors for the occurrence of myocardial ischemia-reperfusion injury (MIRI) during primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI).

Methods: Clinical and angiographic data of 228 AMI patients in whom the infarct-related arteries (IRA) were successfully revascularized by primary PCI were analyzed retrospectively. MIRI was defined if the following conditions existed after PCI: severe bradycardia with hypotension, or lethal ventricular arrhythmias requiring electrical cardioversion, or IRA antegrade flow < or = TIMI 2 grade flow without angiographic evidence of thrombus, emboli, dissection or spasm.
