A B S T R A C TThis study describes the antioxidant, antibacterial activities of five different solvents [methanol, aqueous ethanol (ethanol-water, 70:30, v/v), acetone, ethyl acetate and water extracts of Passiflora wilsonii Hemsl. The results obtained in this study have considerable value with respect to various solvent extracts from Passiflora wilsonii Hemsl., showed varying degrees of antioxidant activity in different test systems in a dose-dependent manner. All solvent extracts of Passiflora wilsonii Hemsl. exhibited scavenging activities toward 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) diammonium salt (ABTS), superoxide anion and hydroxyl radicals. On the other hand, the ethanol fraction showed the highest antioxidant and antibacterial activities in most instances. This study verified that the ethanol extract have strong antioxidant and antibacterial activities which were correlated with its high level of flavonoids.

Background: To our knowledge, only 1 study has investigated the effects of kinesio taping (KT) on pulmonary function and functional capacity of patients with chronic obstructive pulmonary disease (COPD). Therefore, there is still a lack of high-quality evidence to prove the effectiveness of KT for COPD patients. Our purpose was to investigate the effect of KT on respiratory function and muscle strength in the COPD patients who were in stable condition. Methods: This research project has been received ethical approval from the Medical Research and Ethics Committee in Affiliated Nanhua Hospital, University of South China. This work is a part of a comprehensive research project to assess and provide intervention that potentially improves respiratory function and quality of life among patients with COPD. Participants recruited into the study need to fulfill the following criteria: clinical diagnosis of COPD and symptoms indicative of exacerbation; spontaneous breathing on hospital admission; and physiotherapy since the first day of hospitalization. Patients will be assigned at random to the COPD medical treatment + KT (Group 1), or the COPD medical treatment alone (Group 2). The outcome measures are pulmonary function and respiratory muscle strength. The level of statistical significance is set as P < .05. Results: This protocol will provide a reliable theoretical basis for the following research. Conclusions: It was hypothesized that thoracic KT could significantly change pulmonary function and functional capacity in patients with COPD. Trial registration: This study protocol was registered in Research Registry (researchregistry6632).

An ultrasound-assisted extraction technique was used to extract the total flavonoids from QingLi Cao. The optimal conditions were ethanol concentration 59.20%, liquid-to-solid ratio 31.15 mL/g, extraction time 57.42 min and extraction temperature 58.57°C, which were determined using response surface methodology. The antioxidant activities including reducing power, ABTS+, DPPH, superoxide anion and hydroxyl radical were evaluated, which suggested significant antioxidant activities.
