Objective: To observe the effects of inspiratory muscle training under low intensity [20% maximum inspiratory pres- sure (MIP)] and medium intensity (40% MIP) threshold load on diaphragm function, lung function and quality of life in patients with chronic obstructive pulmonary disease (COPD). Methods: 120 COPD patients who were admitted to Heze Hospital of Shandong Provin- cial Hospital from April 2020 to May 2023 were divided into control group, low intensity group and medium intensity group according to the random number table method, with 40 cases in each group. Control group was given routine treatment; On the basis of control group, the low intensity group used 20% MIP as the initial load of inspiratory muscle training; Medium intensity group used 40% MIP as the ini- tial load of inspiratory muscle training. The lung function [forced vital capacity (FVC), MIP, forced expiratory volume in the first second (FEV1), peak expiratory flow (PEF), maximum ventilation volume per minute (MVV)], diaphragm function [diaphragmatic displacement (DE), deep inspiratory diaphragm thickness (DTei) and quiet end-expiratory diaphragm thickness (DTee), diaphragmatic thickness frac- tion (DTF)] and quality of life [COPD quality of life scale (COPD-QOL), St George's respiratory disease questionnaire (SGRQ)] were compared among three groups. Results: After treatment, MIP, FVC, FEV₁, MVV and PEF in control group, low intensity group and medi- um intensity group increased in turn (P<0.05). After treatment, DE, DTei and DTF in control group, low intensity group and medium intensity group increased in turn (P<0.05). After treatment, DTee in control group, low intensity group and medium intensity group decreased in turn (P<0.05). After treatment, the scores of COPD-QOL and SGRQ in control group, low intensity group and medium intensity group decreased in turn (P<0.05). Conclusion: Inspiratory muscle training can effectively improve lung function, diaphragm function and quality of life in COPD patients, and the effect of moderate intensity threshold load is the best.

This study aimed to estimate the optimal light conditions for indoor cultivation of juvenile tiger puffer (Takifugu rubripes), The juvenile fish were exposed to five irradiance of green light (G1: 300 mW/ m², G2: 500 mW/ m², G3: 750 mW/ m², G4: 1 000 mW/ m² and G5: 1 500 mW/ m²), white light (W) and dark (D) for 60 days. At the end of the experiment, the retinal structure of the juvenile fish was observed, and measurements were taken for retinal thickness, expression of visual protein genes, and changes in antioxidant enzyme activity. The results showed that different irradiance of green light had no significant effect on the retinal structure of juvenile fish. Different degrees of melanin migration occurred in the retina of all treatment groups. Melanin granules were more aggregated in the G1 and D groups, while in the G4 and G5 treatment groups, the density of melanin granules was relatively high. The total retinal thickness (TT) decreased with increased green light irradiance. The ratio of the thickness of each retinal layer to the total thickness was further analyzed. The results showed that the changes in retinal thickness showed different trends among different regions, with the G3 group having the highest proportion of the photoreceptor layer (PRos/ is/ TT) (P<0. 05). The proportion of the outer plexiform layer (OPL/ TT) was significantly higher than those in other groups except G1 (P<0. 05). The proportion of outer nuclear layer (ONL/ TT) of juvenile fish in the G2 and G3 groups was significantly higher than that in the G1 and G4 groups (P < 0. 05). There was no significant difference in the proportion of pigment epithelium (RPE/ TT) and ganglion cell layer (GCL/ TT) among different treatment groups (P>0. 05). Regarding the expression of opsin genes, Rod opsin expression was the highest in groups exposed to white light (W)and dark conditions (D)(P<0. 05). SWS2 expression in the G3 group was the highest (P<0. 05). The expression of Opsin3 was the highest in the W group and the G5 group (P<0. 05). For antioxidant enzymes, the activities of Superoxide Dismutase (SOD), Catalase (CAT) and Glutathione Peroxidase (GPX) in the green light treatment groups increased regularly with the increase of light irradiance, and there was no extreme decrease. In view of the effects of different light irradiance on retinal thickness and oxidative stress in eye tissues of juvenile tiger puffer in this study, it is recommended to use a white-colored cultivation substrate and green light in indoor cultivation environments. Additionally, it is advised to control the light irradiance within the range of 500 to 750 mW/ m². [ABSTRACT FROM AUTHOR]
