Exploration of potential biomarkers and therapeutic targets for trauma-related acute kidney injury.

Purpose: Acute kidney injury (AKI) is one of the most common functional injuries observed in trauma patients. However, certain trauma medications may exacerbate renal injury. Therefore, the early detection of trauma-related AKI holds paramount importance in improving trauma prognosis.

Identification of potential biomarkers and therapeutic targets related to post-traumatic stress disorder due to traumatic brain injury.

Background: Post-traumatic stress disorder (PTSD), a disease state that has an unclear pathogenesis, imposes a substantial burden on individuals and society. Traumatic brain injury (TBI) is one of the most significant triggers of PTSD. Identifying biomarkers associated with TBI-related PTSD will help researchers to uncover the underlying mechanism that drives disease development.

A novel artificial intelligence-assisted triage tool to aid in the diagnosis of suspected COVID-19 pneumonia cases in fever clinics.

Background: Currently, the need to prevent and control the spread of the 2019 novel coronavirus disease (COVID-19) outside of Hubei province in China and internationally has become increasingly critical. We developed and validated a diagnostic model that does not rely on computed tomography (CT) images to aid in the early identification of suspected COVID-19 pneumonia (S-COVID-19-P) patients admitted to adult fever clinics and made the validated model available via an online triage calculator.

Methods: Patients admitted from January 14 to February 26, 2020 with an epidemiological history of exposure to COVID-19 were included in the study [model development group (n=132) and validation group (n=32)].

Prediction of fatal adverse prognosis in patients with fever-related diseases based on machine learning: A retrospective study.

Background: Fever is the most common chief complaint of emergency patients. Early identification of patients at an increasing risk of death may avert adverse outcomes. The aim of this study was to establish an early prediction model of fatal adverse prognosis of fever patients by extracting key indicators using big data technology.

Therapeutic effect of ultrasound interventional perirenal catheter-assisted early peripancreatic lavage of protease inhibitor on severe acute pancreatitis in miniature pigs.

Objectives: To study the therapeutic effect of early peripancreatic lavage of ulinastatin on severe acute pancreatitis(SAP).

Methods: Sixteen pigs were divided into 4 groups: model(SAP), saline lavage(SL), ulinastatin lavage(UL), intravenous ulinastatin(IU). UL and SL group were given peripancreatic lavage of ulinastatin by ultrasound-guided perirenal catheterization and IU group was intravenously instilled with ulinastatin.

Association between the T6459C point mutation of the mitochondrial MT-CO1 gene and susceptibility to sepsis among Chinese Han people.

To search for an association between sepsis and mitochondrial genetic basis, we began our study. In this study, a proband harbouring mitochondrial T6459C mutation with sepsis and his Chinese Han pedigree including 7 members of 3 generations were enrolled. General information, blood parameters and mitochondrial full sequence scanning of all members were performed, and cellular functions, including cellular reactive oxygen species (ROS) levels, mitochondrial membrane potential (MMP), degrees of cell apoptosis and adenosine triphosphate (ATP) concentrations, were measured in members with and without the T6459C mutation.

Identification of potential key genes associated with severe pneumonia using mRNA-seq.

This study aimed to identify the potential key genes associated with severe pneumonia using mRNA-seq. Nine peripheral blood samples from patients with severe pneumonia alone (SP group, n=3) and severe pneumonia accompanied with chronic obstructive pulmonary disease (COPD; CSP group, n=3), as well as volunteers without pneumonia (control group, n=3) underwent mRNA-seq. Based on the sequencing data, differentially expressed genes (DEGs) were identified by Limma package.

Clinical analysis of 215 consecutive cases with fever of unknown origin: A cohort study.

Fever of unknown origin (FUO) is a frequently observed phenomenon in clinical practice. The present study was aimed to investigate potential causes of FUO, thereby improving clinical diagnosis of this disorder.In this retrospective study, clinical data were collected from 215 patients who were diagnosed with FUO between January 2009 and December 2010, and an 18 to 36 months follow-up visit was also performed for these patients.

Deep cerebral microbleeds are associated with the severity of lacunar infarcts and hypertension: A retrospective analysis.

Cerebral microbleeds (CMBs) and lacunar infarcts are common manifestations of cerebral small vessel disease. However, the association between the location of CMBs and lacunar infarcts is unclear. Our study aimed to clarify the relationship between the location of CMBs and lacunar infarcts.

Identification of miRNA biomarkers of pneumonia using RNA-sequencing and bioinformatics analysis.

Pneumonia is a lower respiratory tract infection that causes dramatic mortality worldwide. The present study aimed to investigate the pathogenesis of pneumonia and identify microRNA (miRNA) biomarkers as candidates for targeted therapy. RNA from the peripheral blood plasma of participants with pneumonia (severe, n=9; non-severe, n=9) and controls (n=9) was isolated and paired-end sequencing was performed on an Illumina HiSeq4000 system.

Anti‑aging effects of melatonin on the myocardial mitochondria of rats and associated mechanisms.

The present study investigated the anti-aging effects of melatonin on the myocardial mitochondria of D-galactose-aged rats and associated mechanisms. A total of 30 male Sprague‑Dawley (SD) rats were randomly divided into three equal groups: An accelerated aging group that received 125 mg/kg/day D‑galactose; a melatonin‑treated group of D‑galactose‑aged rats that received 10 mg/kg/day melatonin; and a control group receiving normal saline. ATP, ADP and AMP levels in the left ventricular myocardium of rats were determined by high performance liquid chromatography and the total adenylic acid number (TAN) was subsequently calculated.

[Muscle tissue lymphoma presenting only with fever of unknown origin: a case report and literature review].

Extra-nodal malignant lymphoma is often characterized by a lack of typical symptoms and positive results of auxiliary examinations, which make diagnosis difficult. In some cases, fever can be the only clinical manifestation. For the lymphoma patients presenting with persistent fever with a duration over 3 weeks, characteristics of fever including time of fever attack, fever type and effects of drugs may have significant value in the diagnosis, especially in the early stage of the disease or in rare cases.

Effects of emotional and physiological stress on plaque instability in apolipoprotein E knockout mice.

In the present study, we sought to investigate the effects of emotional and physiological stress on plaque instability in atherosclerosis. We used different stress-treated apolipoprotein E (ApoE)-deficient mice, which have been shown to spontaneously develop atherosclerosis with features similar to those seen in humans, as an animal model. Morphology study showed that emotional stress (ES) obviously promoted the development of atherosclerotic plaques and plaque instability evidenced by significantly increasing plaque size, plaque-to-surface ratio and plaque calcification, and enhancing the frequency of large necrotic core and medial erosion compared with control ApoE(-/-) mice (P<0.

Chronic unpredictable stress accelerates atherosclerosis through promoting inflammation in apolipoprotein E knockout mice.

Introduction: Chronic unpredictable stress (CUS) has been suggested to accelerate atherosclerosis. However, the underlying mechanism of this adverse effect is not fully understood. Since chronic stress can promote or even initiate inflammation response, which is thought to be a major contributor to atherogenesis, we postulated that stress-induced inflammatory response might be one important reason for CUS-promoted atherosclerotic disease.
