Objective: This study aimed to detect early changes in left ventricular systolic function in Beagle dogs after radiotherapy using two-dimensional speckle tracking echocardiography and to explore its potential value in evaluating radiation-induced heart disease.

Methods: Thirty-six Beagle dogs were randomized into a control group (n = 18) and an irradiation group (n = 18). The irradiation group received a single dose of 20 Gy to the left ventricular anterior wall, while controls underwent sham irradiation.

Background: Adverse cardiovascular events due to radiation-induced heart disease (RIHD) have become the leading cause of death in cancer survivors, and early screening for RIHD has become an important clinical issue. Our objective was to determine the utility of three-dimensional speckle tracking echocardiography (3D-STE) for detecting RIHD.

Methods: According to inclusion and exclusion criteria, patients with lung cancer who received radiotherapy in our hospital for the first time were recruited as subjects.

Background: Using meta-analysis to evaluate the diagnostic value of contrast-enhanced ultrasound (CEUS) in the diagnosis of papillary thyroid microcarcinoma (PTMC).

Methods: For this systematic review and meta-analysis, we searched PubMed, Cochrane Library, Web of Science, WanFang Data, VPCS Data, and China National Knowledge Infrastructure electronic databases for diagnostic studies on PTMC by CEUS from January 2013 to November 2022. Data were not available or incomplete such as case reports, nonhuman studies, etc, were excluded.

Sentinel lymph node metastasis (SLNM) is a crucial predictor for breast cancer treatment and survival. This study was designed to propose deep learning (DL) models based on grayscale ultrasound, color Doppler flow imaging (CDFI), and elastography images, and to evaluate how DL radiomics can be used to classify SLNM in breast cancer. Clinical and ultrasound data of 317 patients diagnosed with breast cancer at the Second Affiliated Hospital of Nanchang University were collected from January 2018 to December 2021 and randomly divided into training and internal validation cohorts at a ratio of 7:3.

Rationale: Rectal ectopic pregnancy is an extremely rare abdominal pregnancy. This article presents a female underwent an unsuccessful in vitro fertilization which was misdiagnosed by serum beta-human chorionic gonadotropin (β-hCG) test and transvaginal ultrasonography. Twenty days later, a ruptured rectal ectopic pregnancy was confirmed by laparoscopy then the gestational tissue removed successfully.

This study aimed to quantitatively evaluate myocardial work (MW) in advanced stage 3-5 chronic kidney disease (CKD) by a novel non-invasive left ventricular (LV) Pressure-strain loop analysis (PSL). 144 patients with CKD were included (68 with stage 3 CKD group, 76 with stage 4/5 CKD group), and 48 healthy patients were recruited as the control group. All subjects had undergone transthoracic echocardiography.

To develop and to validate a risk-predicted nomogram for downgrading Breast Imaging Reporting and Data System (BI-RADS) category 4a breast lesions. We enrolled 680 patients with breast lesions that were diagnosed as BI-RADS category 4a by conventional ultrasound from December 2018 to June 2019. All 4a lesions were randomly divided into development and validation groups at the ratio of 3:1.

Rationale And Objectives: The sonographic appearance of benign and malignant breast nodules overlaps to some extent, and we aimed to assess the performance of the Gail model as an adjunctive tool to ultrasound (US) Breast Imaging Reporting and Data System (BI-RADS) for predicting the malignancy of nodules.

Materials And Methods: From 2018 to 2019, 2607 patients were prospectively enrolled by 35 health care facilities. An individual breast cancer risk was assessed by the Gail model.

: To assess the performance of elastography (ES) and ultrasound (US) in predicting the malignancy of breast lesions and to compare their combined diagnostic value with that of magnetic resonance imaging (MRI). : The study prospectively enrolled 242 female patients with dense breasts treated in 35 heath care facilities in China between November 2018 and October 2019. Based on conventional US and elastography, radiologists classified the degree of suspicion of breast lesions according to the US Breast Imaging Reporting and Data System (BI-RADS) criteria.

Objective: To investigate the use and trend of drugs on digestive system in Hangzhou area, under the comprehensive statistics index (CSI).

Methods: Using the analytical method related to the sum of consumption and CSI, the application of digestive system drugs of different manufacturers in Hangzhou from 2005 to 2007 was analyzed.

Results: Other than H2 receptor antagonist, the total consumption of digestive system drugs increased yearly, in terms of the total consumption, the first 4 leading ones were proton pump inhibitors, micro ecology medicines, antiemetic drugs and gastroprokinetic agents.
