Ganoderma lucidum (G. lucidum) is a famous medicinal fungus used as a traditional medicine for generations in China. Among bioactivities that G. lucidum possesses, the anti-tumor effect has aroused extensive interests. In this study, one new triterpene (1) was isolated from 90 % ethanol extract of the dried fruiting bodies of G. lucidum. Its structure was determined based on the analysis of its spectroscopic data, including 1D and 2D NMR and MS spectra.Furthermore, 1 elicited moderate anti-tumor activities (IC50 values of 15.38 ± 0.34 and 18.61 ± 0.55 μM for A549 and HepG2 cells, respectively) compared with cisplatin which was employed as the positive drug with IC50 values of 8.21 ± 0.17 and 5.36 ± 0.29 μM for A549 and HepG2 cells, respectively. The mechanism study by RT-qPCR and western blot analysis suggested that the p53/capase-3 pathway is involved in the 1-induced apoptosis.
The aim of this study was to evaluate the characteristics of paediatric hand fractures (PHF) at a tertiary hospital in South China based on sex, age, mechanism of injury and anatomical region. A retrospective observational study was performed on children aged 15 years and younger who were referred for actual or suspected hand fractures between January 2016 and December 2020. Medical records and radiographs were reviewed for age at the time of injury, sex, site and fracture pattern and mechanism of injury. A total of 436 consecutive children with 478 hand fractures were reviewed. Hand fractures was more common in boys (281/436; 64.4%) than in girls (155/436; 35.6%), although most fractures occurred in children aged 0–3 years (198/436; 45.4%). Distal phalanges were the most commonly injured bones (184/478; 38.5%), and the base fractures were most common (151/476; 31.7%); the fifth digit was most commonly injured (150/478; 31.3%). Crush injuries were the leading cause of fracture in children younger than 6 years of age (207/325; 63.7%), whereas punch injuries were the major cause of injury in older age groups (55/153; 35.9%); 60.1% of the fractures were managed nonsurgically. This study showed patterns of PHF in a tertiary hospital in South China. It illustrates the local variability across sex, age group, injury type and injury mechanism. Such demographic data will be valuable for optimally resourcing healthcare systems locally and help guide prevention policies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
