The role of ultrasonographic findings for -mutated, hormone receptor-positive, human epidermal growth factor receptor-2-negative breast cancer.

To determine whether ultrasound (US) features of breast cancer are associated with Breast Imaging and Reporting Data System molecular subtype, histologic grade, and hormone receptor status as well as to assess the predictive value of these features. Retrospective analysis of the medical records of 220 consecutive patients with invasive breast cancer was reviewed according to the -mutated molecular tumor subtype. US findings of all patients were analyzed.

Quantitative evaluation and significance of ultrasound in bronchoalveolar lavage for lung consolidation in children with severe mycoplasma pneumonia.

Background: The aim of this study was to evaluate the effect of lung ultrasound on bronchoalveolar lavage in the treatment of mycoplasma pneumonia in children.

Methods: Thirty children with mycoplasma pneumonia who were treated with medication and bronchial lavage were selected. We collected the results of laboratory and imaging examinations after admission, and the changes in lung consolidation area were examined by ultrasound before, immediately upon completion, and at 1, 3, and 7 days after bronchoalveolar lavage.

New application of multimodal ultrasound imaging for identification of myofascial trigger points in the trapezius muscle.

Background: The study aimed to quantify the characteristics of trapezius myofascial trigger points (MTrPs) using shear wave elastography (SWE) and contrast-enhanced ultrasound (CEUS) and explore the application value of the new ultrasound techniques in identifying MTrPs.

Methods: Forty patients participated in this study. MTrPs in the trapezius muscle were determined by palpation, and SWE and CEUS were used to quantify the focal and adjacent areas.

The role of ultrasound in determining the amount of pleural effusion.

Background: There is no standardized system to evaluate pleural effusion size on ultrasound (US). We aimed to explore the role of US in determining the amount of pleural effusion, with an attempt to provide evidence for clinical efficacy evaluation and treatment program selection.

Methods: A total of 98 patients undergoing thoracoscopy at our center were enrolled in this study.

Specification and guideline for technical aspects and scanning parameter settings of neonatal lung ultrasound examination.

Lung ultrasound (LUS) is now widely used in the diagnosis and monitor of neonatal lung diseases. Nevertheless, in the published literatures, the LUS images may display a significant variation in technical execution, while scanning parameters may influence diagnostic accuracy. The inter- and intra-observer reliabilities of ultrasound exam have been extensively studied in general and in LUS.

Application of lung ultrasonography in critically ill patients with COVID-19.

Purpose: Lung ultrasonography (LU) is useful to assess lung lesions and variations at bedside. To investigate the results of LU in severe and critical patients with coronavirus disease 2019 (COVID-19), we performed a single-institution study to evaluate the related lung lesions and variations, and prophylactic strategies, in a large referral and treatment center.

Methods: We included 91 adult patients with severe and critical COVID-19, namely 62 males and 29 females, with an average age of 59 ± 11 years, who underwent LU.

A Multicenter Large-Sample Shear Wave Ultrasound Elastographic Study of the Achilles Tendon in Chinese Adults.

Objectives: The changes in the viscoelasticity of the Achilles tendon are related to tendinopathy. Therefore, constructing a data model in the healthy population is essential to understanding the key factors affecting the viscoelasticity of the Achilles tendon. The purpose of our research was to obtain large sample data, construct a data model, and determine parameters that affect the elastic modulus of the Achilles tendon in healthy Chinese adults.

Development of a highly sensitive fluorescent light-up probe for G-quadruplexes.

G-quadruplexes are higher-order nucleic acid structures that have attracted extensive attention because of their biological significance and potential applications in supramolecular chemistry. An ever-increasing interest in G-quadruplexes has promoted the development of selective and sensitive fluorescent probes as research tools for these structures. However, most current studies primarily focus on the improved selectivity of probes for G-quadruplexes.

Estimation of critical gap based on Raff's definition.

Critical gap is an important parameter used to calculate the capacity and delay of minor road in gap acceptance theory of unsignalized intersections. At an unsignalized intersection with two one-way traffic flows, it is assumed that two events are independent between vehicles' arrival of major stream and vehicles' arrival of minor stream. The headways of major stream follow M3 distribution.

Application of laparospic ultrasonography in surgery of small renal cell carcinoma.

Purpose: : To assess the clinic value of application of laparospic ultrasonography (LU) in partial nephrectomy of small renal cell carcinoma.

Materials And Methods: From 2007 to 2011, 28 small renal cell carcinoma patients in ou clinic underwent laparoscopic partial nephrectomy with LU. For comparison with preoperative conventional ultrasound and CT, we collected ultrasonic performance of the affected side kidney, renal tumor location, size, echo change, blood supply situation and the relationship with the surrounding tissue.

Comparison of ultrasound echo-tracking technology and pulse wave velocity for measuring carotid elasticity among hemodialysis patients.

This study aims to investigate the correlation between carotid elasticity in hemodialysis patients as evaluated by ultrasound echo-tracking technology and aortic pulse wave velocity. A total of 103 patients with end-stage renal disease who underwent stable hemodialysis were enrolled. An ultrasonic echo-tracking method was used to evaluate the elastic modulus and the stiffness index (β), which were compared with pulse wave velocity (PWV).

Prevalence of deep venous thrombosis in patients with acute exacerbation of chronic obstructive pulmonary disease.

Background: Acute exacerbation of chronic obstructive pulmonary disease (COPD) is always associated with a high incidence and mortality. Because of the presence of some concomitant risk factors such as immobilization, bronchial superinfection, patients who are admitted for acute exacerbations of COPD are generally considered to be at moderate risk for the development of venous thromboembolism. In this study, we investigated the prevalence and the clinical manifestations of deep venous thrombosis (DVT) in patients with acute exacerbation of COPD.

Association of serum pentosidine with arterial stiffness in hemodialysis patients.

Pentosidine is an advanced glycation end product (AGE). The present study was undertaken to investigate the association of serum pentosidine with carotid distensibility as a measure of arterial stiffness in hemodialysis patients. One hundred and three patients on maintenance hemodialysis were recruited.
