RESUMO
Background: The literature suggests that the medical community needs musicians to provide an insider's perspective to understand the physical and psychological dimensions of playing an instrument, and healthcare providers need to understand musicians' experiences in order to develop coping strategies. Compared with professional pianists, student pianists are a neglected group. However, student and professional pianists both want to maintain their playing careers and have the experience of giving up playing because of playing-related musculoskeletal disorder (PRMD). There are a few studies conducted on student pianists' experiences with PRMD, but none have been conducted in the Chinese context. Given the distinctive characteristics of higher music education in China and Chinese piano students, this study aims to investigate the lived experiences of tertiary student pianists with PRMD. Methods: Phenomenology is the most suitable qualitative method for investigating lived experiences. This study employed a transcendental phenomenological approach to investigate the experiences of student pianists, collecting data through one-on-one interviews and focus group discussions. Since phenomenological research emphasizes the homogeneity of research subjects, all 25 participants in this study are tertiary student pianists from seven Chinese higher education institutions. Results: Four themes and ten sub-themes were identified in this study. They are as follows: Theme one, Perceptions of PRMD, with sub-themes of body perceptions, negative thought, and emotional changes; Theme two, Complex Identity, with sub-themes of future pianists' identity, nuanced identity of student pianists, and the dual identity between student pianist and patient; Theme three, Coping Strategies, with sub-themes of self-regulation and actively seek help from social relations; Theme four, Influences and Meanings, with sub-themes of negative influences of PRMD and positive meanings of PRMD. Conclusion: This study explores the experiences of tertiary student pianists with PRMD, including their subjective thoughts and feelings. It also highlights the importance of understanding tertiary student pianists' experiences in developing health education and healthcare measures tailored to them.
RESUMO
ObjectiveTo explore the effects of Wumeisan on gut lactase activity and microflora diversity of mice with dysbacteriosis diarrhea. MethodThe mice were randomly divided into 4 groups， namely， the normal group， the model group， and the low-dose and high-dose Wumeisan groups， with 8 mice in each group. The mouse model was made by gavage of mixed antibiotics for 7 d， and the low-dose and high-dose Wumeisan groups （5.98， 11.96 g·kg-1） were given gavage for 7 d continuously. The normal group and the model group were given the same volume of sterile water. The changes in the body weight， food intake， and diarrhea of mice were recorded. Feces were collected after the last administration， and the lactase activity was detected by the colorimetric method. The gut microbiota changes were detected by the 16S rRNA high-throughput sequencing technology. ResultCompared with those in the normal group， the mice in the model group had dilute and soft stools， reduced body mass， reduced food intake， reduced lactase activity， significantly reduced intestinal flora diversity， and significant changes in the relative abundance phylum and genus levels of flora. Compared with the model group， Wumeisan reduced the diarrhea rate of mice， promoted the rapid recovery of body weight and food intake， increased the lactase activity decreased by antibiotic， improved the community abundance and diversity of mice with dysbacteriosis， and made the species composition closer to that in the normal group. The abundance of three phyla （Bacteroidota， Proteobacteria， Verrucomicrobiota） and nine genera （Odoribacter， Enterococcus， Clostridium innocuum group， etc.） of mice with diarrhea were regulated by Wumeisan. Among them， norank f Muribaculaceae， norank f norank o Clostridia UCG-014， Lachnospiraceae NK4A136 group， and Odoribacter showed significant positive correlation with the body weight and lactase activity， and Escherichia-Shigella， Enterobacter， Enterococcus， and Clostridium innocuum group showed significant positive correlation with the diarrhea rate. Function prediction showed that the high-dose Wumeisan significantly reseted 6 functional levels of metabolism， genetic information processing， and human diseases， and had positive effects on endocrine and metabolic diseases， immune diseases， infectious disease， and parasitic infectious diseases. ConclusionWumeisan can relieve the symptoms of dysbacteriological diarrhea by increasing the lactase activity and regulating the gut microbiota composition.
