Purpose: To investigate the efficacy of ultrasound (US)-guided percutaneous MWA for benign thyroid nodules with cosmetic problems and identify related factors contributing to post-ablative complete relief (CR).
Methods: This retrospective study reviewed the efficacy of MWA in treating thyroid nodules in patients with cosmetic problems who underwent MWA from January 2021 to May 2023. Patients were followed up at 1, 3, and 6 months after MWA.
Protein kinase C (PKC) regulates diverse biological functions of cancer cells and is a promising therapeutic target. However, clinical trials of PKC-targeted therapies have not yielded satisfactory results. Recent studies have also indicated a tumor-suppressive role of PKCs unclear molecular mechanisms.

Methods: This retrospective study was conducted between March 2020 and January 2023, enrolling 52 patients with symptomatic focal uterine adenomyosis who had undergone MWA. All patients were examined with CEUS before and after MWA.
Purpose: We aimed to develop a 4-level risk stratification model using a scoring system based on conventional ultrasound to improve the diagnosis of gallbladder polyp.
Method: Patients with histopathologically confirmed gallbladder polyps were consecutively recruited from three medical centres. Conventional ultrasound findings and clinical characteristics were acquired prior to cholecystectomy.
Objective: Endomyocardial biopsy is the gold standard method for the diagnosis of cardiac allograft rejection. However, it causes damage to the heart. In this study, we developed a noninvasive method for quantification of granzyme B (GzB) by targeted ultrasound imaging, which detects and provides quantitative information for specific molecules, for acute rejection assessment in a murine cardiac transplantation model.

Herein, we report the injectable thermosensitive hydrogel by confining curcumin (Cur)-loaded hollow mesoporous organosilica nanoparticles (Cur@HMON@gel) which can locate in tumor site more than half a month and mop up the residual RCC under ultrasound (US) irradiation after transforming from colloidal sol status to elastic gel matrix at physiological temperature. Based on the US-triggered accelerated diffusion of the model chemotherapy drug with multi-pharmacologic functions, the sustained and controlled release of Cur has been demonstrated .

Methods: In total, 284 consecutive patients (166 men, 118 women; mean age, 43.0 ± 18.
Unlabelled: Inactivating mutations of von Hippel-Lindau (VHL) are highly prevalent in clear cell renal cell carcinoma (ccRCC). Improved understanding of the vulnerabilities of VHL-deficient ccRCC could lead to improved treatment strategies. The activity of DNA dioxygenase ten-eleven translocation (TET)2 is significantly reduced in multiple cancers by different mechanisms, but its role in ccRCC progression remains unclear.

A total of 115 kidney transplantation recipients were consecutively enrolled in this prospective study. The patients were subdivided into two groups using 1 mo post-transplantation as the cutoff time for determining the development of acute rejection (AR).

Background: A preoperative diagnosis of primary hepatic lymphoma (PHL) can have profound therapeutic and prognostic implications. Because of the rarity of PHL, however, there are few reports on diagnostic imaging. We reviewed the clinical and radiologic findings of 29 patients with PHL, the largest series to date, to evaluate the diagnostic features of this disease.
View Article and Find Full Text PDFPurpose: This study aimed to evaluate the application of quantitative contrast-enhanced ultrasonography (CEUS) in the assessment of renal allograft dysfunction and to establish a new noninvasive index to predict acute rejection (AR).
Methods: Fifty-seven renal transplant recipients were enrolled in this prospective study. Before renal allograft biopsy, CEUS examinations were performed.
Acoustic radiation force impulse (ARFI) quantification, a novel ultrasound-based elastography method, has been used to measure liver fibrosis. However, few studies have been performed on the use of ARFI quantification in kidney examinations. We evaluated renal allograft stiffness using ARFI quantification in patients with stable renal function (n = 52) and those with biopsy-proven allograft dysfunction (n = 50).

Objective: To investigate the sonographic features of the cervical lymph nodes in rabbit VX2 tongue carcinoma model and hyperplasia cervical lymph nodes model using gray scale contrast-enhanced ultrasonography (CEUS) after intravenous administration of SonoVue (a sonographic contrast agent) and to evaluate the potential utility of CEUS in detecting early metastatic cervical lymph nodes in the rabbit VX2 tongue carcinoma model.
Methods: Twenty New Zealand rabbits were placed into 2 groups, 12 for node metastasis and 18 for node hyperplasia. Cervical CEUS was performed in the rabbits of both groups before and after intravenous administration of SonoVue(0.
