Multidimensional Ultrasound Evaluation of Diastasis Recti Abdominis During Different Gestational Periods.

Objective: The purpose of this study is to explore the application value of two-dimensional ultrasound and shear wave elastography (SWE) in the multidimensional evaluation of diastasis recti abdominis (DRA) during different gestational periods.

Methods: A cohort of 202 gravidas that were examined in our hospital between June 2021 and September 2022 were selected for the purpose of the study, which included 26 cases with <14 weeks of pregnancy, 36 cases in the 14th-27th week of pregnancy, 36 cases in the 28th-34th week of pregnancy, 32 cases in the 35th-38th week of pregnancy, 45 cases at 42 days postpartum, and 27 cases at 3 months postpartum. The inter-rectus distance (IRD) and the thickness in each gestational period were measured, and Young's modulus of the rectus abdominis at different gestational periods was measured using SWE by two sonographers.

An Ultrasound Model to Predict the Short-Term Effects of Endovascular Stent Placement in the Treatment of Carotid Artery Stenosis.

The present study aimed to explore the predictive ability of an ultrasound linear regression equation in patients undergoing endovascular stent placement (ESP) to treat carotid artery stenosis-induced ischemic stroke. Pearson's correlation coefficient of actual improvement rate (IR) and 10 preoperative ultrasound indices in the carotid arteries of 64 patients who underwent ESP were retrospectively analyzed. A predictive ultrasound model for the fitted IR after ESP was established.

A Meta-Analysis on the Relationship Between Hair Dye and the Incidence of Non-Hodgkin's Lymphoma.

Background: Epidemiologic studies have suggested hair dye to be a risk factor for many cancers. However, previous studies on the association between the personal use of hair dye and risk of non-Hodgkin's lymphoma (NHL) have been inconclusive.

Methods: The PubMed, Embase, Cochrane Library, and Web of Science databases, as well as the references cited in included studies, were searched for relevant studies up to February 10, 2015.

miR-139 acts as a tumor suppressor in T-cell acute lymphoblastic leukemia by targeting CX chemokine receptor 4.

MicroRNAs (miRNAs) act as tumor regulators in T-cell acute lymphoblastic leukemia (T-ALL). However, the molecular mechanisms by which miRNA-139 (miR-139) regulates T-ALL remain unclear. In this study, we found that miR-139 was lowly expressed whereas C-X-C chemokine receptor type 4 (CXCR4) was highly expressed in T-ALL cell lines and patient samples.

Ultrasonography for Preoperative Diagnosis of Retroperitoneal Fibrosis.

This study aimed to assess the application of ultrasonography for preoperative diagnosis of retroperitoneal fibrosis (RPF). A total of 51 patients with clinically suspected RPF underwent transabdominal ultrasonography and ultrasound-guided histopathologic biopsy (tAU-UGHB). Retroperitoneal fibrosis was diagnosed in 35 patients; of these, 31 cases (88.

Relationship between cigarette smoking and risk of chronic myeloid leukaemia: a meta-analysis of epidemiological studies.

Objective: Previous epidemiologic studies that have been reported on the association between cigarette smoking and risk of chronic myeloid leukaemia (CML) have remained controversial. A comprehensive meta-analysis was performed to evaluate smoking as a potential relationship factor and incidence of CML.

Methods: Systematic literatures collected from articles published before August 2015 were searched from PubMed, EMBASE and the Cochrane Library.

[Echocardiographic standardized myocardial segmentation features in patients with left ventricular noncompaction].

Objective: To analyze the echocardiographic standardized myocardial segmentation features in patients with left ventricular noncompaction (LVNC).

Methods: Echocardiographic characteristics of 9 patients with LVNC were analyzed and the localization of lesions were determined according to the standardized myocardial segmentation (SMS) recommended by American Heart Association (AHA).

Results: Loose trabeculation in the myocardial lesions were evidenced in all LVNC patients.
