The diagnositic value of dynamic contrast-enhanced ultrasound for evaluation of tissue oxygen status in rat hepatoma model.

Background: Hypoxia is a characteristic of solid tumors, but whether significant hypoxia exists in the hepatocellular carcinoma remains unclear. This animal study aims to explore the value of dynamic contrast-enhanced ultrasound (CEUS) quantitative parameters to evaluate the oxygen status in two rat hepatoma models.

Materials And Methods: N1S1 and McA-RH7777 S-D rat orthotopic hepatoma models were established.

A Nomogram Based on Contrast-Enhanced Ultrasound to Predict the Microvascular Invasion in Hepatocellular Carcinoma.

Objective: The aim of this study was to establish and validate a contrast-enhanced ultrasound (CEUS) nomogram for pre-operative microvascular invasion (MVI) prediction in hepatocellular carcinoma (HCC), and compare it with the nomogram based on gadopentetate dimeglumine-enhanced magnetic resonance imaging (Gd-MRI).

Methods: A total of 251 patients with a single HCC were enrolled in this prospective study, including 176 patients in the training cohort and 75 patients in the validation cohort. Contrast-enhanced ultrasound (CEUS) with Sonazoid and Gd-MRI was performed pre-operatively.

Ring-like enhancement on Contrast-Enhanced ultrasound may correlate well with histopathological capsule of Hepatocellular Carcinoma: Comparison with the enhancing capsule on Gadopentetate-enhanced MRI.

Purpose: To evaluate the correlation of ring-like enhancement (RE) on contrast-enhanced ultrasound with Sonazoid (S-CEUS) with the fibrous capsule of HCC, and compared it with the enhancing capsule on Gadopentetate-enhanced MRI (Gd-MRI).

Method: Consecutive patients with pathologically-proven resected HCCs from January 2021 to December 2021 were reviewed in this retrospective study. Preoperatively, the RE on the S-CEUS and the enhancing capsule on Gd-MRI were evaluated for each lesion.

Intraarterial contrast-enhanced ultrasound to predict the short-term tumour response of hepatocellular carcinoma to Transarterial chemoembolization with Lipiodol.

Background: Transarterial chemoembolization (TACE) is an effective locoregional therapy in hepatocellular carcinoma (HCC). However, it is difficult to predict the tumour response (TR) of TACE intraprocedurally. The aim of this study was to predict the TR after TACE (1-3 months) in HCC patients using intraprocedural intraarterial contrast enhanced ultrasound (IA-CEUS).

Dihydroartemisinin Alleviates Imiquimod-Induced Psoriasis-like Skin Lesion in Mice Involving Modulation of IL-23/Th17 Axis.

Psoriasis is a T help 17 (Th17) cell-mediated chronic inflammatory skin disease. Recent studies have shown that dihydroartemisinin (DHA) can significantly reduce experimental autoimmune encephalomyelitis and rheumatoid arthritis by regulating Th17 cells. To verify whether DHA can improve the symptoms of psoriasis and to further explore the possible mechanism.

[Value of Contrast-enhanced Ultrasound in Differential Diagnosis between Cholesterol Polyp and Gallbladder Adenoma].

Objective To compare the performance of contrast-enhanced ultrasound(CEUS)and ultrasound(US)in the differential diagnosis between cholesterol polyps and gallbladder adenomas. Methods A total of 136 patients with gallbladder polyp lesions(GPLs)and undergoing cholecystectomy in the First Medical Center of Chinese PLA General Hospital from January 2019 to October 2020 were retrospectively analyzed.All the patients underwent US and CEUS examinations before cholecystectomy.

Prognostic value of T cell immunoglobulin mucin-3 in prostate cancer.

Background: Optimal treatment for prostate cancer remains a challenge worldwide. Recently, T cell immunoglobulin mucin-3 (TIM-3) has been implicated in tumor biology but its contribution prostate cancer remains unclear. The aim of this study was to investigate the role of TIM-3 as a prognostic marker in patients with prostate cancer.
