Article Abstract
Uncontrolled hemorrhage after trauma to the liver can lead to death. The present study compared the effects of non-focused microbubble-enhanced ultrasound and high-intensity focused ultrasound on hepatic hemostasis in the injured liver. Blood perfusion level, serum liver enzyme levels and the aspartate transaminase/alanine transaminase ratio differed between the two types of treatment (all p values < 0.05). Hepatic cells in the microbubble-enhanced ultrasound group exhibited edema and compressed the hepatic sinus and blood vessels in the portal area. Coagulation and necrosis, inflammatory cell infiltration, and fibrous tissue encapsulation were observed in the high-intensity focused ultrasound group at later stages. The groups also differed in degree of ultrastructural damage and recovery time. Thus, microbubble-enhanced ultrasound has less of an impact on blood reperfusion and surrounding normal tissue than high-intensity focused ultrasound and is a better choice for the treatment of liver trauma.

Low-Intensity Focused Ultrasound Stimulation (LIFU) is a noninvasive and nondestructive neuromodulatory method with growing evidence for the safe and effective treatment of chronic pain. However, the effect of LIFU applied to the spine region, including the spinal cord and dorsal root ganglia, is not well understood. In this work, we review current advances in LIFU of the spine region for the treatment of chronic neuropathic pain and movement disorders to explore potential clinical applications and indicate a direction for future study.

Introduction: Tumor tissues exhibit significantly lower oxygen partial pressure compared to normal tissues, leading to hypoxia in the tumor microenvironment and result in resistance to tumor treatments. Strategies to mitigate hypoxia include enhancing blood perfusion and oxygen supply, for example,by decomposing hydrogen peroxide within the tumor. Improving hypoxia in the tumor microenvironment could potentially improve the efficacy of cancer treatments.

Background: With rising demand for non-invasive body contouring, this study aimed to evaluate the efficacy and safety of non-focused, low-intensity ultrasound for lower abdominal lipolysis.
Methods: The enrolled subjects prospectively received 6 weekly sessions of well-setting ultrasound treatment with frequency of 1 MHz and an intensity of 2.2 W/cm2, to target the subcutaneous fat of lower abdomen with three regions (left, middle, and right).
