RESUMO Introdução: O envelhecimento populacional na crescente industrialização e urbanização nacional lastreia um estilo de vida insalubre onde a prevenção e o controle de doenças crônicas são dificultosos. Aproximadamente 68% dos idosos possuem algum tipo de doença crônica, majoritariamente de cunho musculoesquelético com destaque para a articulação do joelho, comprometendo a autonomia e prejudicando seu convívio social, com impactos psicológicos à longo prazo. Os esportes de equipe sugerem grande potencial terapêutico nesse grupo, porém há poucos estudos nesse sentido. Objetivo: Analisar a situação do esporte de equipe entre os idosos, propondo métodos para prevenir lesões articulares no joelho e testar o efeito preventivo dessas implementações. Métodos: Foram selecionados 92 voluntários idosos que participaram de esportes comunitários. Para entender as causas e os principais tipos de lesões articulares do joelho, os idosos foram analisados durante os esportes comunitários, incluindo a utilização do método FMS para a realização de testes de saúde. Resultados: Após os testes, pode-se ver que a pontuação média da FMS de todos os idosos da comunidade é de 14,23 pontos, e a pontuação total é de 12,00-17,00; a pontuação média da lesão geral da articulação do joelho é aumentada em 2,65, e o escore médio de FMS da lesão articular feminina do joelho é muito beneficiado. Conclusão: Após a proposta de medidas preventivas focadas na articulação do joelho, os resultados dos exames de AFF dos idosos da comunidade foram significativamente aprimorados, indicando que as ações propostas são eficazes e merecem ser replicadas. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

ABSTRACT Introduction: The aging population in the growing national industrialization and urbanization supports an unhealthy lifestyle where the prevention and control of chronic diseases are difficult. Approximately 68% of the elderly have some type of chronic disease, mostly musculoskeletal, especially in the knee joint, compromising their autonomy and affecting their social life, with psychological impacts in the long term. Team sports suggest great therapeutic potential in this group, but there are few studies. Objective: Analyze the situation of team sports among the elderly, propose methods to prevent knee joint injuries, and test these implements’ preventive effects. Methods: 92 elderly volunteers who participated in community sports were selected. To understand the causes and main types of knee joint injuries, the elderly were analyzed during community sports, including using the FMS method for health testing. Results: After the tests, it can be seen that the mean FMS score of all the community elderly is 14.23 points, and the total score is 12.00-17.00; the mean score of the overall knee joint injury is increased by 2.65, and the mean FMS score of the female knee joint injury is greatly benefited. Conclusion: After the proposed preventive measures focused on the knee joint, the AFF examinations of the community elderly were significantly improved, indicating that the proposed actions are effective and deserve to be replicated. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

RESUMEN Introducción: El envejecimiento de la población en la creciente industrialización y urbanización nacional favorece un estilo de vida poco saludable donde la prevención y el control de las enfermedades crónicas son difíciles. Aproximadamente el 68% de los ancianos tienen algún tipo de enfermedad crónica, en su mayoría de naturaleza musculoesquelética con énfasis en la articulación de la rodilla, comprometiendo la autonomía y perjudicando su vida social, con impactos psicológicos a largo plazo. Los deportes de equipo sugieren un gran potencial terapéutico en este grupo, pero hay pocos estudios en este sentido. Objetivo: Analizar la situación de los deportes de equipo entre las personas mayores, proponiendo métodos para prevenir las lesiones de la articulación de la rodilla y comprobar el efecto preventivo de estas implementaciones. Métodos: Se seleccionaron 92 voluntarios de edad avanzada que participaban en deportes comunitarios. Para comprender las causas y los principales tipos de lesiones de la articulación de la rodilla, se analizó a los ancianos durante la práctica de deportes comunitarios, incluso utilizando el método FMS para las pruebas de salud. Resultados: Después de las pruebas, se puede observar que la puntuación media de FMS de todos los ancianos de la comunidad es de 14,23 puntos, y la puntuación total es de 12,00-17,00; la puntuación media de la lesión general de la articulación de la rodilla se incrementa en 2,65, y la puntuación media de FMS de la lesión de la articulación de la rodilla femenina se ve muy beneficiada. Conclusión: Tras las medidas preventivas propuestas centradas en la articulación de la rodilla, los resultados de los exámenes de AFF de los ancianos de la comunidad mejoraron significativamente, lo que indica que las acciones propuestas son eficaces y merecen ser replicadas.

Abstract Resin AB-8 was screened from seven resins with different polarity and particle size because of its better decoloration and deproteinization efficiency to polysaccharide from the root of Actinidia valvata (AvPs), and then the optimized parameter conditions were applied by the single-factor experiments and were shown as follows: a concentration of crude polysaccharide of 3 mg/mL, an adsorption time of 40 min, an initial pH of 7.0, a flow rate of 1.5 BV/h. In addition, the results of HPGPC, FT-IR, PMP-HPLC-DAD, 1H NMR and Congo red test showed that the sugar chain, structural group, monosaccharide composition and triple-helix conformation structure of AvPs were not broken during resin AB-8 treatment. Moreover, AvPs could keep the stability of biological activity after the resin AB-8 treatment, and revealed an obviously antioxidant and anticancer activities in vitro as well. This research suggests that this method is promising for the deproteinization and decolorization of AvPs which could be explored as a potential antioxidant or anticancer agent for use in functional food or medicine.

Abstract The aim of this paper is to identify and investigate an endophytic fungus (strain 28) that was isolated from Houttuynia cordata Thunb, a famous and widely-used Traditional Chinese Medicine. Based on morphological methods and a phylogenetic analysis of ITS sequences, this strain was identified as Chaetomium globosum. An antifungal activity bioassay demonstrated that the crude ethyl acetate (EtOAc) extracts of strain 28 had a wide antifungal spectrum and strong antimicrobial activity, particularly against Exserohilum turcicum (Pass.) Leonard et Suggs, Botrytis cinerea persoon and Botrytis cinerea Pers. ex Fr. Furthermore, the fermentation conditions, extraction method and the heat stability of antifungal substances from strain 28 were also studied. The results showed that optimal antifungal activity can be obtained with the following parameters: using potato dextrose broth (PDB) as the base culture medium, fermentation for 4–8 d (initial pH: 7.5), followed by extraction with EtOAc. The extract was stable at temperatures up to 80 °C. This is the first report on the isolation of endophytic C. globosum from H. cordata to identify potential alternative biocontrol agents that could provide new opportunities for practical applications involving H. cordata.
