A nomogram model of spectral CT quantitative parameters and clinical characteristics predicting lymphovascular invasion of gastric cancer.

Objective: The study established a nomogram based on quantitative parameters of spectral computed tomography (CT) and clinical characteristics, aiming to evaluate its predictive value for preoperative lymphovascular invasion (LVI) in gastric cancer (GC).

Methods: From December 2019 to December 2021, 171 patients with pathologically confirmed GC were retrospectively collected with corresponding clinical data and spectral CT quantitative data. Patients were divided into LVI-positive and LVI-negative groups based on their pathological results.

Preoperative prediction of lymphovascular and perineural invasion in gastric cancer using spectral computed tomography imaging and machine learning.

Background: Lymphovascular invasion (LVI) and perineural invasion (PNI) are important prognostic factors for gastric cancer (GC) that indicate an increased risk of metastasis and poor outcomes. Accurate preoperative prediction of LVI/PNI status could help clinicians identify high-risk patients and guide treatment decisions. However, prior models using conventional computed tomography (CT) images to predict LVI or PNI separately have had limited accuracy.

Clinical application of super-low-positioned intestinal decompression tube in the treatment of intestinal obstruction: a pilot study.

Objective: This study aimed to evaluate the clinical application and efficacy of a super-low-positioned intestinal decompression tube in the treatment of intestinal obstruction.

Methods: A total of 130 patients with postoperative small bowel obstruction were included in this study. The patients were divided into a super-low-positioned intestinal decompression group and a conventional intestinal decompression group.

Short-term outcomes of a new gastrointestinal decompression tube combined with conservative treatment in patients with esophagojejunal anastomotic leakage after total gastrectomy.

To compare the short-term outcomes of a new gastrointestinal decompression tube combined with conservative treatment in patients with esophagojejunal anastomotic leakage (EJAL) after total gastrectomy. We retrospectively analyzed the data of 81 patients with EJAL who had undergone total gastrectomy and Roux-en-Y reconstruction at Fujian Medical University Union Hospital between January 2014 and December 2021. The patients were divided into experimental (12 patients with new gastrointestinal decompression tube plus conservative treatment) and control (69 patients with conservative treatment) groups, according to the different treatment methods they received.

Effect of Cerebral Ischemic Strokes in Different Cerebral Artery Regions on Left Ventricular Function.

Objectives: The relationship between cerebral ischemic stroke and left ventricular function evaluated by echocardiography has been emphasized. Whether lesions in different cerebral artery regions would result in left ventricular dysfunction remains uncertain.

Methods: Patients were divided into middle cerebral artery (MCA) ( = 79), posterior cerebral artery (PCA) ( = 64), basilar artery (BA) regions ( = 66), and no-ischemic stroke group ( = 209).

Brain white matter abnormalities and correlation with severity in amyotrophic lateral sclerosis: An atlas-based diffusion tensor imaging study.

Objectives: To assess microstructural alterations in white matter (WM) in amyotrophic lateral sclerosis (ALS) using diffusion tensor imaging (DTI).

Methods: DTI data were collected from 34 subjects (18 patients with ALS and 16 healthy controls). The atlas-based region of interest (ROI) analysis was conducted to assess WM microstructure in ALS by combining intra-voxel metrics, which included fractional anisotropy (FA) and mean diffusivity (MD), and an inter-voxel metric, i.

Abnormal cerebral microstructures revealed by diffusion kurtosis imaging in amyotrophic lateral sclerosis.

Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease in which cerebral structural impairment is a consistent feature.

Purpose: To investigate cerebral microstructural changes in ALS using diffusion kurtosis imaging (DKI) for the first time.

Study Type: Prospective.

[Impact of plateau environment on seminal characteristics of native Tibetans and immigrated Tibetan Hans].

Objective: To investigate the characteristics of the semen parameters of native Tibetans and immigrated Tibetan Hans in the high-altitude area and analyze the influence of altitude adaptation on male fertility.

Methods: This study included 1 563 infertile male patients, including 698 native Tibetans and 865 immigrated Tibetan Hans, and 56 normal fertile men, including 33 native Tibetans and 23 Tibetan Hans. We obtained semen samples from the subjects for routine semen analysis and sperm DNA fragmentation index (DFI) examination and collected peripheral blood for determination of the reproductive hormone levels.

Giant cell tumour of tendon sheath with bone invasion in extremities: analysis of clinical and imaging findings.

Purpose: The purpose of this study was to review the clinical and imaging characteristics of giant cell tumour of tendon sheath (GCTTS) with bone invasion.

Materials And Methods: Radiography (n = 9), magnetic resonance imaging (MRI) (n = 7), computed tomography (CT) (n = 4) and clinical findings of nine patients with surgically and pathologically confirmed GCTTS with bone invasion were retrospectively reviewed. Specific imaging findings including tumour site, maximum tumour size, shape, margin, density or signal intensity, bone invasion, periosteal reaction, calcification, and cystic areas were documented.

[Susceptibility-weighted imaging in detecting brain iron accumulation of Parkinson's disease].

Objective: to evaluate the clinical value of susceptibility-weighted imaging (SWI) in the measurement of brain iron in Parkinson's disease at 3.0 Tesla MRI.

Methods: a total of 30 patients with clinical diagnosis Parkinson's Disease (PD) and 19 age-matched normal controls took the brain MR examination with conventional and SWI sequences.
