Regulation of the β‑catenin/LEF‑1 pathway by the siRNA knockdown of RUVBL1 expression inhibits breast cancer cell proliferation, migration and invasion.

RUVBL1 is a protein characterized by its DNA‑dependent ATPase activity and DNA deconjugating enzyme function. It is a member of the ATPase (AAA+) protein family associated with various cellular processes. Available research confirms that the expression of RUVBL1 is upregulated in breast cancer (BRCA) cell lines; however, the mechanisms underlying its functional role in BRCA remain unclear.

Multiparametric US for Identifying Metabolic Dysfunction-associated Steatohepatitis: A Prospective Multicenter Study.

Background Noninvasive evaluation of metabolic dysfunction-associated fatty liver disease (MAFLD) with multiparametric US is essential, but multicenter studies are lacking. Purpose To evaluate the ability of multiparametric US with attenuation imaging (ATI) and two-dimensional (2D) shear-wave elastography (SWE) for predicting metabolic dysfunction-associated steatohepatitis (MASH) in participants with MAFLD, regardless of hepatitis B virus infection status. Materials and Methods This prospective cross-sectional multicenter study of consecutive adults with MAFLD who underwent multiparametric US with ATI and 2D SWE, as well as liver biopsy, from September 2020 to June 2022 was conducted in 12 tertiary hospitals in China.

Analysis of differentially expressed proteins in lymph fluids related to lymphatic metastasis in a breast cancer rabbit model guided by contrast‑enhanced ultrasound.

The aim of the present study was to identify differentially expressed proteins in the lymph fluid of rabbits with breast cancer lymphatic metastasis compared with healthy rabbits and to analyze and verify these proteins using proteomics technologies. In the process of breast cancer metastasis, the composition of the lymph fluid will also change. Rabbits with breast cancer lymph node metastasis and normal rabbits were selected for analysis.

The potential role of combined shear wave elastography and superb microvascular imaging for early prediction the pathological response to neoadjuvant chemotherapy in breast cancer.

Objectives: The potential role of shear wave elastography (SWE) and superb microvascular imaging (SMI) for early assessment of treatment response to neoadjuvant chemotherapy (NAC) in breast cancer remains unexplored. This study aimed to identify potential factors associated with the pathological response to NAC using these advanced ultrasound techniques.

Methods: Between August 2021 and October 2022, 68 patients with breast cancer undergoing NAC were recruited.

PAIP2 is a potential diagnostic and prognostic biomarker of breast cancer and is associated with immune infiltration.

Breast cancer is the second highest incidence of cancer in the world. It is of great significance to find biomarkers to diagnose breast cancer and predict the prognosis of breast cancer patients. PAIP2 is a poly (A) -binding protein interacting protein that regulates the expression of VEGF.

Differential Diagnosis Value of Shear-Wave Elastography for Superficial Enlarged Lymph Nodes.

Objectives: To evaluate the diagnostic efficiency and diagnostic threshold of conventional US and shear-wave elastography (SWE) in superficial enlarged lymph nodes (LNs).

Methods: A total of 204 patients with superficial enlarged LNs were enrolled in this retrospective study aged 46.0 ± 15.

Low-Intensity Focused Ultrasound-Augmented Multifunctional Nanoparticles for Integrating Ultrasound Imaging and Synergistic Therapy of Metastatic Breast Cancer.

The metastasis of breast cancer is believed to have a negative effect on its prognosis. Benefiting from the remarkable deep-penetrating and noninvasive characteristics, sonodynamic therapy (SDT) demonstrates a whole series of potential leading to cancer treatment. To relieve the limitation of monotherapy, a multifunctional nanoplatform has been explored to realize the synergistic treatment efficiency.

2020 Chinese guidelines for ultrasound malignancy risk stratification of thyroid nodules: the C-TIRADS.

Thyroid nodules are very common all over the world, and China is no exception. Ultrasound plays an important role in determining the risk stratification of thyroid nodules, which is critical for clinical management of thyroid nodules. For the past few years, many versions of TIRADS (Thyroid Imaging Reporting and Data System) have been put forward by several institutions with the aim to identify whether nodules require fine-needle biopsy or ultrasound follow-up.

Evaluation of Adenoid Hypertrophy with Ultrasonography.

Objectives: To determine the reliability of ultrasound in the diagnosis of adenoid hypertrophy in children.

Methods: The subjects were divided into three groups: Group A: Pre-experiment group: 30 children who were hospitalized for adenoidal hypertrophy were selected, and preoperative ultrasound was used to measure adenoid thickness. Their re-confirmed Adenoid ultrasound measurement thickness was obtained during surgery under the guidance of metal instruments; Group B: Ultrasound screening group: 1898 children aged 3-12 y were selected, and their adenoids were examined by ultrasonography to observe the size, shape, echo and blood flow of adenoids and the thickness of adenoids; Group C: Surgical resection group: 133 hospitalized patients were selected, and their adenoid ultrasound measurement thickness (AUT), the adenoid-nasopharynx (A/N) ratio was calculated based on nasopharyngeal lateral radiographs and obstruction ratio was obtained in electronic nasopharyngoscopy [extent of adenoid-posterior nostril occlusion (EANC)] were compared.

[Establishment of lymph node metastasis of MDA-MB-231 breast cancer model in nude mice].

Objective: To establish lymph node metastasis of breast cancer model in nude mices using MDA-MB-231 cell lines or tumor masses.

Methods: Divided twelve female nude mices of five weeks into A, B groups randomly. A group had seven nude mices, B group had five nude mices.
