Purpose: According to International Lymphology Society guidelines, the severity of lymphedema is determined by the difference in volume between the affected limb and the healthy side divided by the volume of the healthy side. However, this method of measuring volume is time-consuming, laborious, and has certain errors in clinical applications.Therefore, this study aims to explore whether machine learning radiomics features based on non-contrast magnetic resonance imaging (NCMRI) can predict the severity of primary lower limb lymphedema.

- Carboxylesterase is an important industrial enzyme used in sectors like fine chemistry and bioremediation, but its limited thermostability poses challenges for industrial use.
- Researchers discovered a novel carboxylesterase (EstF) from Streptomyces lividans TK24 that shows optimal activity at 55 °C and high stability, with a half-life of 387.23 hours at that temperature.
- By using site-directed mutation to introduce a single glycine, the mutant EstF showed a significant increase in half-life at 100 °C without losing catalytic efficiency, suggesting new methods for improving enzyme stability.
Objectives: To observe the effects of acupuncture pretreatment on toll-like receptor 9/myeloid differentiation factor 88/nuclear factor-κB (TLR9/MyD88/NF-κB) signaling pathway and inflammatory response in the rats with exercise-induced skeletal muscle damage (EIMD) and explore the underlying mechanism of this pretreatment for EIMD.
Methods: A total of 88 male SD rats were randomly divided into a blank group (8 rats), a model group (40 rats) and an acupuncture pretreatment group (40 rats). In the model group and the acupuncture pretreatment group, 5 subgroups were randomized according to the sampling time of 0, 12, 24, 48 and 72 h of modeling, with 8 rats in each one, respectively.
Acupuncture pretreatment (AP) has a good skeletal muscle protective effect. The present study investigated whether acupuncture pretreatment could improve ultrastructural changes and skeletal muscle inflammation in exercising skeletal muscle injury. Eighty-eight male SD rats were randomly divided into a blank group (C), an exercise group (E), and an acupuncture pretreatment group (AP).

- The study used bibliometric and scientific knowledge graph methods to analyze current research trends in acupuncture-moxibustion for treating myofascial pain syndrome (MPS), reviewing articles up to March 2023 from various databases.
- A total of 910 Chinese articles and 300 English articles were included, showing an increasing trend in publications, but limited cooperation among different regions, primarily focused in Spain, China, and the U.S.
- Keyword analysis revealed that Chinese studies emphasized "acupuncture" and related techniques, while English studies leaned towards "dry needling" and "injection"; both types of articles were deficient in studying the underlying mechanisms of these therapies, highlighting the need for increased collaboration and comprehensive research efforts.
