[Influence of axial rotation on measurement of medial proximal tibial angle].

Objective: To measure and compare medial proximal tibial angle (MPTA) of lower limbs under different axial rotation angles(neutral position, 30° internal rotation, 30° external rotation) on the load position radiographs, and explore changes and significance of MPTA measured within and between groups of tibia at different axial rotation positions.

Methods: From January 2018 to December 2018, 40 patients with knee osteoarthritis (KOA) were selected, with a total of 80 limbs, including 12 males and 28 females, aged from 29 to 73 years old with an average of (59.6±12.

Clinical and electrocardiographic features in acute total left main coronary artery occlusion without collateral circulation.

Backgrounds: Study concerning the clinical features, electrocardiogram (ECG) findings and outcomes in patients presenting with acute total occlusion of left main coronary artery (LM) without collateral circulation is limited.

Methods: 25 patients with acute total LM occlusion without collateral circulation by emergency coronary angiography, from muti-center registry, were retrospectively studied. The clinical and angiographic characteristics, ECG and in-hospital mortality were reviewed.

Association of admission hyperglycemia and all-cause mortality in acute myocardial infarction with percutaneous coronary intervention: A dose-response meta-analysis.

Objective: The aim of this study is to evaluate the associations between admission hyperglycemia and the risk of all-cause mortality in patients with acute myocardial infarction (AMI) with or without diabetes, to find optimal admission glucose intervention cut-offs, and to clarify the shape of the dose-response relations.

Methods: Medline/PubMed and EMBASE were searched from inception to 1 April 2022. Cohort studies reporting estimates of all-cause mortality risk in patients with admission hyperglycemia with AMI were included.

Acceleration of Brain TOF-MRA with Compressed Sensitivity Encoding: A Multicenter Clinical Study.

Background And Purpose: The clinical practice of three-dimensional TOF-MRA, despite its capability in brain artery assessment, has been hampered by the relatively long scan time, while recent developments in fast imaging techniques with random undersampling has shed light on an improved balance between image quality and imaging speed. Our aim was to evaluate the effectiveness of TOF-MRA accelerated by compressed sensitivity encoding and to identify the optimal acceleration factors for routine clinical use.

Materials And Methods: One hundred subjects, enrolled at 5 centers, underwent 8 brain TOF-MRA sequences: 5 sequences using compressed sensitivity encoding with acceleration factors of 2, 4, 6, 8, and 10 (CS2, CS4, CS6, CS8, and CS10), 2 using sensitivity encoding with factors of 2 and 4 (SF2 and SF4), and 1 without acceleration as a reference sequence (RS).

Diagnostic efficacy of intravascular ultrasound combined with GdO-EPL contrast agent for patients with atherosclerosis.

Atherosclerosis is a cardiovascular disease that is pathologically associated with the growth of atherosclerotic plaques and vascular vulnerability. Intravascular ultrasound (IVUS) has been used to evaluate and treat cardiovascular diseases. Accumulating evidence has demonstrated that GdO-doped nanoparticles contrast can be applied for the diagnosis of human diseases.

Evolutionary de Winter pattern: from de Winter ECG to STEMI-A case report.

Background: De Winter pattern is associated with acute occlusion in the left anterior descending coronary artery combined with upsloping ST-segment depression at the J point in leads V through V without ST-segment elevation. The ECG changes in this case were illustrated by an up-sloping ST-segment depression in the V to V leads, followed by tall and symmetrical T waves. Changes from de Winter to ST-segment elevation myocardial infarction (STEMI) are rare.

The association between dietary protein intake and esophageal cancer risk: a meta-analysis.

Several papers studied dietary protein intake as a potential influence factor for esophageal cancer, but their findings were inconsistent. Thus, this meta-analysis was performed to identify the effect of protein intake on esophageal cancer risk. Potential case-control studies or cohort studies from the databases of Embase, Web of Science and PubMed were searched.

Long-term treatment with 3,4-methylenedioxymethamphetamine caused retina damage in C57BL/6 mice.

Purpose: As a class of psychostimulant drugs, amphetamines are widely abused for their stimulant, euphoric, and hallucinogenic properties. Many of these effects result from acute increases in dopamine and serotonin neurotransmission. Following the onset of these effects, 3,4 methylenedioxymethamphetamine produces persistent damage to dopamine and serotonin nerve terminals, resulting in long-lasting neurotoxicity.

[Retrospective study on incomplete intestinal obstruction treated with the adjuvant therapy of acupuncture and moxibustion].

Objective: To evaluate the clinical effects on incomplete intestinal obstruction treated with the adjuvant therapy of acupuncture and moxibustion.

Methods: Using the retrospective analysis, 80 patients of incomplete intestinal obstruction were divided into an observation group and a control group, 40 cases in each one. In the control group, the routine treatment was given, such as fasting, gastrointestinal decompression, parenteral nutrition, infection prevention with antibiotics and enema laxative.

Sperm tsRNAs contribute to intergenerational inheritance of an acquired metabolic disorder.

Increasing evidence indicates that metabolic disorders in offspring can result from the father's diet, but the mechanism remains unclear. In a paternal mouse model given a high-fat diet (HFD), we showed that a subset of sperm transfer RNA-derived small RNAs (tsRNAs), mainly from 5' transfer RNA halves and ranging in size from 30 to 34 nucleotides, exhibited changes in expression profiles and RNA modifications. Injection of sperm tsRNA fractions from HFD males into normal zygotes generated metabolic disorders in the F1 offspring and altered gene expression of metabolic pathways in early embryos and islets of F1 offspring, which was unrelated to DNA methylation at CpG-enriched regions.

Inhibitory effect of caffeic acid on ADP-induced thrombus formation and platelet activation involves mitogen-activated protein kinases.

Caffeic acid (CA), one of the active constituents of Radix Salvia miltiorrhizae, exhibits antioxidant and anti-inflammatory activities. However, few studies have assessed the ability of CA to inhibit platelet mediated thrombus generation in vivo. In this study, we investigated the antithrombotic effect of CA in mouse cerebral arterioles and venules using intravital microscopy.

[Effects of panax notoginseng saponins on expression of intercellular adhesion molecule-1 in human umbilical vein endothelial cells injury induced by oxidized low-density lipoprotein].

Objective: To study the protective effect of panax notoginseng saponins (PNS) on human umbilical vascular endothelial cells (HUVECs) injury induced by oxidized low-density lipoprotein (ox-LDL) for investigating the mechanism of PNS in treating arteriosclerosis obliterans (ASO).

Methods: Taking the cultured HUVECs as target cells, ox-LDL was used to establish a model of injured HUVEC and it was then intervened by PNS. The morphologic changes of HUVEC were observed under light microscope; activity of cells was determined by MTT method; the adhesive percentage between ox-LDL treated HUVEC and monocyte detennined by protein quantification and the protein expression of intercellular adhesion molecule-1 (ICAM-1) determined by flow cytometry.
