Classification of Neoadjuvant Therapy Response in Patients With Colorectal Liver Metastases Using Contrast-Enhanced Ultrasound-With Histological Pathology as the Gold Standard.

Objective: To evaluate the response to neoadjuvant therapy in patients with colorectal liver metastases (CRLMs) using ultrasound(US) and contrast-enhanced ultrasound(CEUS), with correction to the tumor regression grade (TRG) of pathological results.

Methods: This study included patients with resectable CRLMs admitted from February to December 2022. After at least 4 cycles neoadjuvant therapy, all the patients received US and CEUS examinations within two weeks before hepatectomy.

Multimode Ultrasound Model for Predicting the Early Treatment Response of Anti-VEGF Agents Plus Anti-PD-1 Antibody in Patients with Unresectable Hepatocellular Carcinoma.

Objective: The purpose of the study described was to establish prediction models to initially screen the beneficiary patients with unresectable hepatocellular carcinoma (HCC) in the treatment of anti-vascular endothelial growth factor (VEGF) agents plus anti-programmed cell death-1 (PD-1) antibody.

Methods: A total of 62 patients were enrolled in this study. All patients underwent ultrasound (US), color ddoppler flowing imaging (CDFI), contrast-enhanced ultrasound (CEUS) and laboratory examinations within 2 wk before the treatment.

Changes in Autophagy Levels in Rat Myocardium During Exercise Preconditioning-Initiated Cardioprotective Effects.

The role of autophagy in the cardioprotection conferred by ischemic preconditioning (IPC) has been well described. This study aimed to investigate the changes in autophagy levels during the cardioprotective effects initiated by exercise preconditioning (EP).Rats were randomly divided into 4 groups: group C (control), group EP, group EE (exhaustive exercise), and group EP + EE (EP pretreatment at 0.

Intraoperative radiation therapy as part of planned monotherapy for early-stage breast cancer.

Introduction: Adjuvant whole breast radiation therapy has developed into the standard of care for patients following a lumpectomy for early-stage breast cancer. However, there is recent interest in intraoperative radiation therapy (IORT) to minimize toxicity while still improving local control beyond surgical resection and anti-estrogen therapy alone.

Materials And Methods: All patients were evaluated pre-operatively in a multidisciplinary clinic setting at a community hospital for suitability for breast conservation therapy.

[Effect of Dexmedetomidine Combined Electrical Stimulation on Coanitive Function of Patients Receiving Extracerebral Intervention].

Objective: To explore the effect of dexmedetomidine combined electrical stimulation on cognitive function of neurosurgical diseases patients treated by extracerebral intervention.

Methods: Totally 122 patients with neurosurgical diseases who underwent selective intervention were randomly assigned to the observation group and the control group, 61 cases in each group. Patients in the control group recieved anesthesia by dexmedetomidine.

The Effect of Atorvastatin on Breast Cancer Biomarkers in High-Risk Women.

Statins have the potential to reduce breast cancer incidence and recurrence as shown in both epidemiologic and laboratory studies. The purpose of this study was to evaluate the effect of a lipophilic statin, atorvastatin, on breast cancer biomarkers of risk [mammographic density (MD) and insulin growth factor 1 (IGF-1)] in high-risk premenopausal women.Premenopausal women at increased risk for breast cancer received either 40 mg of atorvastatin or placebo for 1 year.

[Protection of Transcutaneous Acupoint Electrical Stimulation for Brain Injury Undergoing Intervention: a Clinical Observation].

Objective: To observe the effect of transcutaneous acupoint electrical stimulation (TAES) combined dexmedetomidine on hemodynamic of intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention, and their protection for brain Injury.

Methods: Totally 108 intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention were randomly assigned to the electroacupuncture (EA) group and the control group according to random digit table, 54 in each group. All patients were anesthetized with dexmedetomidine.

Comparison of false positive rates for screening breast magnetic resonance imaging (MRI) in high risk women performed on stacked versus alternating schedules.

Purpose: Breast MRI added to mammography increases screening sensitivity for high-risk women but false-positive (FP) rates are higher and the optimal screening schedule for coordination with mammography is unclear. We compare rates of FP MRI when studies were performed on two different schedules.

Patients And Methods: High-risk women at the University of Vermont who had at least 1 MRI and 1 mammogram performed within one year between 2004-2012 were eligible for inclusion in this study.

Therapeutic effects of 5-fluorouracil sustained-release particles in 81 malignant pericardial effusion patients.

This study aimed to investigate the clinical application value of the 5-fluorouracil (5-FU) sustained-release particles implanted along the cardiac tangent direction into malignant pericardial effusion (MPCE). A total of 81 MPCE patients underwent pericardiocentesis, and were implanted with 5-FU sustained-release particles into the pericardial cavity under ultrasound guidance. The puncturing path was along the cardiac tangent direction.

A modified chordal transfer technique to treat anterior mitral leaflet prolapse.

Chordal transfer from the intact posterior mitral leaflet (PML) to the anterior mitral leaflet (AML) is an effective way to correct anterior leaflet prolapse and provides good long-term results. However, it is difficult to determine the accurate segment of the PML which needs to be transferred and the suture point of the leaflets. We describe a modified technique to determine the correct segment that needs to be transferred to effectively correct AMLs with elongated or ruptured chordae.
