Background: Large calves are considered unattractive. Botulinum toxin type A (BoNT-A), acting as a neurotoxin that reduces muscle contraction, is widely used in calf contouring. However, there lacks detailed anatomical data to guide clinical injection.
Objectives: This study aims to use ultrasonography to provide depth information of the calf muscles and determine the morphological types of the gastrocnemius muscle.
Methods: Ultrasound scanning was performed at six sites on 40 Chinese adults. A real-time ultrasound scannerwas used to detect the depth of the gastrocnemius muscle and the soleus muscle.
Results: The thickness of the gastrocnemius muscle and the soleus muscle was measured. The depth from the skin to the surface, the middle, and the bottom of the gastrocnemius muscle was measured. The morphology of gastrocnemius muscle was classified into four different types under ultrasound according to the muscle bulge pattern.
Conclusion: This study took ultrasonic measurements of Asian calves to guide accurate and effective BoNT-A injection in real clinical practice.

Gluteus medius contracture: A case report and review of the literature.
Medicine (Baltimore)

Department of Orthopedics, China-Japan Union Hospital of Jilin University, Changchun, Jilin Province, PR China.
Rationale: Bilateral gluteus medius contractures in adults are rare in clinical practice, with only a few cases reported. These contractures may result from repeated intramuscular injections during childhood. Understanding the clinical manifestations, diagnostic process, treatment, and outcomes can provide insights into effective management strategies.

The unique architecture of the liver consists of hepatic lobules, dividing the hepatic features of metabolism into 2 distinct zones, namely the pericentral and periportal zones, the spatial characteristics of which are broadly defined as metabolic zonation. R-spondin3 (Rspo3), a bioactive protein promoting the Wnt signaling pathway, regulates metabolic features especially around hepatic central veins. However, the functional impact of hepatic metabolic zonation, regulated by the Rspo3/Wnt signaling pathway, on whole-body metabolism homeostasis remains poorly understood.

Department of Orthopaedics, Lanzhou University Second Hospital, Lanzhou, Gansu Province, China.
Purpose: This meta-analysis was carried out to evaluate the clinical effectiveness of rotator cuff repair surgery in treating rotator cuff tears in individuals with mild glenohumeral osteoarthritis (GHOA).
Methods: A computer-based search was conducted across multiple databases including PubMed, Embase, Web of Science, and Cochrane Library using the keywords "Shoulder Joints", "Osteoarthrosis", and "rotator cuff". Only studies focusing on patients with GHOA who underwent rotator cuff repair were considered for inclusion.
Unraveling the transcriptomic effects of leucine supplementation on muscle growth and performance in basketball athletes.
PLoS One
January 2025
School of Physical Education and Sports Science, South China Normal University, Guangzhou, China.
Leucine has gained recognition as an athletic dietary supplement in recent years due to its various benefits; however, the underlying molecular mechanisms remain unclear. In this study, 20 basketball players were recruited and randomly assigned to two groups. Baseline exercise performance-assessed through a 282-foot sprint, free throws, three-point field goals, and self-rated practice assessments-was measured prior to leucine supplementation.

Objectives: To evaluate the value of ultrasound (US) and shear wave velocity (SWV) to assess muscle in postmenopausal women with osteosarcopenia (OSP).
Methods: This study included 145 postmenopausal women, comprising 115 osteopenia/osteoporosis participants without sarcopenia (OP alone) and 30 OSP participants. All received the evaluation of bone mineral density (BMD), appendicular skeletal muscle mass index (ASMI), handgrip strength, calf circumference, 6-meter walking speed, and 5-time chair stand test.
