Postoperative pulmonary complications in older patients undergoing elective surgery with a supraglottic airway device or tracheal intubation.

The two most commonly used airway management techniques during general anaesthesia are supraglottic airway devices and tracheal tubes. In older patients undergoing elective non-cardiothoracic surgery under general anaesthesia with positive pressure ventilation, we hypothesised that a composite measure of in-hospital postoperative pulmonary complications would be less frequent when a supraglottic airway device was used compared with a tracheal tube. We studied patients aged ≥ 70 years in 17 clinical centres.

Correlation Analysis of Ultrasound Elastography Score with Invasive Breast Cancer and Biological Prognostic Factors.

Invasive breast cancer (IBC) is a kind of malignant tumor in which cancer cells have broken through the basement membrane of breast ducts or lobular acini and invaded the stroma. Although ultrasound elastography score (UES) has shown unique advantages in the diagnosis of IBC, its value in the prognosis is not clear. Here, we explored the correlation of UES with IBC and biological prognostic factors.

Imaging analysis of the malignant transformation of bile duct hamartomas in the liver: A case report and literature review.

Bile duct hamartoma in the liver (LBDH) is relatively rare among the hepatic space-occupying lesions that occur in adults, and the malignant transformation of LBDH is even rarer. In the present case report, a 63-year-old male was found to have two space-occupying lesions in the right lobe of the liver upon ultrasound examination. Enhanced computed tomography (CT) suggested benign hepatic haemangioma, and contrast-enhanced ultrasonography (CEUS) suggested well-differentiated hepatocellular carcinoma.

Value of PTEN and Echocardiography in Predicting the Efficacy of Trimetazidine Combined with Metoprolol in the Treatment of Heart Failure.

Objective: To investigate the predictive value of PTEN and echocardiography in the treatment of heart failure with trimetazidine combined with metoprolol.

Methods: A total of 100 patients with coronary heart disease and HF who admitted to our hospital from August 2018 to August 2020 were enrolled into research. All patients received routine treatment according to the guidelines and were treated with trimetazidine and metoprolol for a total course of 6 months.

Application of quantitative analysis of contrast-enhanced ultrasonography in the evaluation of acute radiation-induced liver damage.

The aim of the present study was to evaluate the microcirculation perfusion in patients with acute radiation-induced liver damage (RILD) and explore the feasibility of non-invasive evaluation of RILD using quantitative analysis of contrast-enhanced ultrasound (CEUS). Patients who successfully underwent three-dimensional conformal intensity-modulated radiotherapy for abdominal tumors were selected. CEUS was performed on the liver prior to and 2, 3 and 4 weeks after exposure, and the time-intensity curve (TIC) was obtained by quantitative analysis of CEUS.

Quantitative analysis of contrast-enhanced ultrasonography in acute radiation-induced liver injury: An animal model.

The aim of the present study was to examine and assess contrast-enhanced ultrasound in the early diagnosis of acute radiation-induced liver injury in a rat model. Sixty female rats were used, with 50 rats being utilized to produce an animal model of liver injury with a single dose of stereotactic X-ray irradiation of 20 Gy. Ten rats from the injury group and 2 rats from the control group were randomly selected on days 3, 7, 14, 21 and 28, and examined by contrast-enhanced ultrasound and histopathology of liver specimens.
