Objective To find out whether photobiomodulation(PBM)can mitigate cognitive dysfunction caused by chronic stress by affecting levels of adenosine triphosphate(ATP)and adenosine receptors.Methods Twenty-four C57BL/6J mice were randomly divided into a control group,a stress group,and a treatment group.Chronic unpredictable mild stress was used to establish a mouse model of stress.Six weeks into modeling,the treatment group was subjected to one week of PBM interventions.Behavioral tests were conducted to observe behavioral changes in the mice.Western blotting(WB)was used to detect the expressions of A1,A2B,and A3 adenosine receptors in the hippocampus and prefrontal cortex of mice in the three groups.Twelve C57BL/6J mice were randomly divided into a control group and an intervention group.The intervention group received a week of PBM interventions and underwent behavioral testing.WB was used to detect the expression changes of A1,A2B,and A3 adenosine receptors in the hippocampus and prefrontal cortex in both groups.Immunofluorescence assay was adopted to detect the expression of c-Fos in the hippocampus of mice in the two groups.The ATP assay kit made by Beyotime Biotechnology Co.,Ltd.was used to measure changes in ATP contents in the hippocampus and prefrontal cortex tissues of mice.Cell experiments were conducted to verify the effect of PBM on intracellular ATP contents.Results Mice in the stress group covered a similar distance to the control group,but finished far fewer platform crossings.There was no significant difference between the treatment group and the control group in the number of times of platform crossings,but compared favorably with the stress group where the levels of adenosine receptors in the hippocampus and prefrontal cortex were lower,but were increased by PBM.After PBM interventions in normal mice,platform crossings were increased significantly compared to the control group.PBM also raised adenosine receptor levels and ATP contents in the hippocampus and prefrontal cortex,and increased hippocampal c-Fos expressions.In vitro,PBM elevated intracellular ATP levels.Conclusion PBM may improve chronic stress-induced cognitive dysfunction by regulating ATP levels and adenosine receptor expressions,thereby modulating neuronal responsiveness in the hippocampus.

Objective To explore the impact of nausea and vomiting management program based on shared decision-making on post-transarterial chemoembolization(TACE)nausea and vomiting in liver cancer patients.Methods A shared decision-making aid was designed,and nausea and vomi-ting management program was developed.A total of 100 liver cancer patients who underwent TACE treatment in the Department of Interventional Radiology at Nantong Third People's Hospital from Janu-ary to December 2023 were selected as study subjects.The control group(admitted from January to June 2023)received routine TACE perioperative nursing care,while the experimental group(admit-ted from July to December 2023)implemented the nausea and vomiting management program in addi-tion to routine care.The incidence and severity of nausea and vomiting within 24 hours post-surgery,as well as the vomiting-related functional living index,quality of life,and self-efficacyin decision-making before and after the intervention were compared between the two groups.Results Within 24 hours post-surgery,the incidence and severity of nausea and vomiting in the experimental group were lower than those in the control group,with statistically significant differences(P＜0.05).After the in-tervention,the total and dimensional scores of the Quality of Life in Liver Cancer(QOL-LC)scale and the vomiting-related functional living index in the experimental group were higher than those in the control group(P＜0.05).Additionally,the self-decision-making efficacy score in the experimental group was higher after the intervention than before intervention and higher than that in the control group(P＜0.05).Conclusion The nausea and vomiting management program based on shared decision-making can effectively reduce the incidence and severity of post-TACE nausea and vomiting in liver cancer patients,and improve their quality of life,vomiting-related functional living index,and self-decision-making efficacy.

Objective To explore the effect of tongue pressure resistance feedback training in the rehabilitation of dysphagia in patients with ischemic stroke(IS).Methods A total of 100 pa-tients with dysphagia after IS were randomly divided into control group(receiving conventional reha-bilitation therapy and oral motor training)and experimental group(receiving tongue pressure resist-ance feedback training on the basis of conventional rehabilitation therapy),with 50 patients in each group.The treatment duration was 4 weeks for both groups.During the study,3 patients dropped out due to personal reasons,and ultimately 49 patients in the control group and 48 patients in the experi-mental group completed the study.Before and after treatment,tongue muscle function was measured in both groups;videofluoroscopic swallowing studies(VFSS)were used to measure temporal and kinemat-ic parameters of swallowing;the Rosenbek Penetration-Aspiration Scale(PAS)was used to assess aspi-ration risk;the Stroke and Aphasia Quality of Life Scale(SWAL-QOL)was used to evaluate quality of life;and occurrence of complications in both groups were compared.Results After 4 weeks of treat-ment,peak tongue pressure,mean tongue pressure,and tongue pressure duration increased inboth groups,with these indicators being higher in the experimental group than in the control group;oral transit time,soft palate elevation time,and hyoid bone displacement time shortened,while upper esoph-ageal sphincter(UES)opening time and laryngeal closure time prolonged,hyoid and thyroid cartilage movement(upward and anterior displacement)and UES opening degree increased,and pharyngeal contractile ratio(PCR)decreased in both groups,with these indicators being superior in the experi-mental group compared to the control group;PAS scores decreased and SWAL-QOL scores increased in both groups,with PAS scores being lower and SWAL-QOL scores being higher in the experimental group compared to the control group;the differences between the two groups in the aforementioned indicators were statistically significant(P＜0.05).The complication rate was 4.17％(2/48)in the experimental group and 10.20％(5/49)in the control group,with no statistically significant difference(P＞0.05).Conclusion Tongue pressure resistance feedback training can improve tongue function and swallowing function,effectively reduce the risk of aspiration after swallowing,and enhance the quality of life of patients with dysphagia after IS during their rehabilitation treatment.
