The participation of multidisciplinary health focuses on weight loss, freely and spontaneously, or on the indication of bariatric surgery. We know how difficult it is to lose weight. In order to achieve successful procedures, we recommend the “Obese Workshop” or pre- and post-surgical follow-ups close to the patients, with a view to avoiding recurrences or the “accordion effect” (very common), which can interfere with the Body Mass Index (BMI). Everyone, males and females, complained of tiredness and the impossibility of any physical exercise, even the lightest and simplest to be performed, in addition to the fact that they cannot attend gyms and are unable to open a simple door handle.展开更多

METHODS: A Swedish population-based cross-sectional survey was conducted. Participants aged 40-79 years were randomly selected from the Swedish Registry of the Total Population. Data on physical activity, GERD, body mass index (BMI) and the covariates age, gender, comorbidity, education, sleeping problems, and tobacco smoking were obtained using validated questionnaires. GERD was self-reported and defined as heartburn or regurgitation at least once weekly, and having at least moderate problems from such symptoms. Frequency of physical activity was categorized into three groups: (1) "high" (several times/week); (2) "intermediate" (approximately once weekly); and (3) "low" (1-3 times/mo or less). Analyses were stratified for participants with "normal weight" (BMI < 25 kg/m 2 ), "overweight" (BMI 25 to ≤ 30 kg/m 2 ) and "obese" (BMI > 30 kg/m 2 ). Multivariate logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for potential confounding by covariates. RESULTS: Of 6969 eligible and randomly selected individuals, 4910 (70.5%) participated. High frequency of physical activity was reported by 2463 (50%) participants, GERD was identified in 472 (10%) participants, and obesity was found in 680 (14%). There were 226 (5%) individuals with missing information about BMI. Normal weight, overweight and obese participants were similar regarding distribution of gender and tobacco smoking status, while obese participants were on average slightly older, had fewer years of education, more comorbidity, slightly more sleeping problems, lower frequency of physical activity, and higher occurrence of GERD. Among the 2146 normal-weight participants, crude point estimates indicated a decreased risk of GERD among individuals with high frequency of physical activity (OR: 0.59, 95% CI: 0.39-0.89), compared to low frequency of physical activity. However, after adjustment for potential confounding factors, neither intermediate (OR: 1.30, 95% CI: 0.75-2.26) nor high (OR: 0.99, 95% CI: 0.62-1.60) frequency of physical activity was followed by decreased risk of GERD. Sleeping problems and high comorbidity were identified as potential confounders. Among the 1859 overweight participants, crude point estimates indicated no increased or decreased risk of GERD among individuals with intermediate or high frequency of physical activity, compared to low frequency. After adjustment for confounding, neither intermediate (OR: 0.75, 95% CI: 0.46-1.22) nor high frequency of physical activity were followed by increased or decreased risk of GERD compared to low frequency among nonobese participants. Sleeping problems and high comorbidity were identified as potential confounders for overweight participants. In obese individuals, crude ORs were similar to the adjusted ORs and no particular confounding factors were identified. Intermediate frequency of physical activity was associated with a decreased occurrence of GERD compared to low frequency of physical activity (adjusted OR: 0.41, 95% CI: 0.22-0.77). CONCLUSION: Intermediate frequency of physical activity might decrease the risk of GERD among obese individuals, while no influence of physical activity on GERD was found in non-obese people.展开更多

Physical exercise has been long recog- nized for its therapeutic effects on depressive disorders, although knowledge of the underlying mechanisms remains limited. Suppressed hippocampal neurogenesis in adult brains has been regarded, at least partly, contributive to depression, whereas physical exercise that restores neuro- genesis accordingly exerts the anti-depressive action. Several recent publications have suggested the potential role of adiponectin, a protein hormone secreted by peripheral mature adipocytes, in mediating physical exercise-triggered enhancement of hippocampal neurogenesis and alleviation of depression. Here, we briefly review these novel findings and discuss the possibility of counter- acting depression by modulating adiponectin signaling in the hippocampus with interventions including physical exercise and administration of pharmacological agents.展开更多

Among the variousmechanisms underlying the association between physical exercise and brain health, recent evidence attests that neurotrophin receptor signalingmay have an important role, because the activation of this pathway leads to growth and differentiation of new neurons and synapses, supportsaxonal and dendritic growth, fosters synaptic plasticity, and preserves survival of existing neurons. In this review of published evidence, we highlightthat a positive relationship exists between physical exercise and circulating brain-derived neurotrophic factor levels and that the postexercisevariation of this molecule is associated with improvement of neurocognitive functioning. Less clear evidence has instead been published forother neurotrophins, such as nerve growth factor, neurotrophin-3, and neurotrophin-4. Overall, promotion of adequate volumes and intensities ofphysical exercise (i.e., approximately 3 months of moderate-intensity aerobic exercise, with 2—3 sessions/week lasting not less than 30 min)may hence be regarded as an inexpensive and safe strategy for boosting brain-derived neurotrophic factor release, thus preserving or restoringcognitive functions.展开更多

文摘Alzheimer's disease is the primary cause of dementia and imposes a significant socioeconomic burden globally.Physical exercise,as an effective strategy for improving general health,has been largely reported for its effectiveness in slowing neurodegeneration and increasing brain functional plasticity,particularly in aging brains.However,the underlying mechanisms of exercise in cognitive aging remain largely unclear.Adiponectin,a cell-secreted protein hormone,has recently been found to regulate synaptic plasticity and mediate the antidepressant effects of physical exercise.Studies on the neuroprotective effects of adiponectin have revealed potential innovative treatments for Alzheimer's disease.Here,we reviewed the functions of adiponectin and its receptor in the brains of human and animal models of cognitive impairment.We summarized the role of adiponectin in Alzheimer's disease,focusing on its impact on energy metabolism,insulin resistance,and inflammation.We also discuss how exercise increases adiponectin secretion and its potential benefits for learning and memory.Finally,we highlight the latest research on chemical compounds that mimic exerciseenhanced secretion of adiponectin and its receptor in Alzheimer's disease.

文摘White matter injury is a key factor impacting stroke recovery.Physical exercise can promote white matter repair.Immune cells,especially regulatory T(Treg)cells,contribute to strengthening white matter integrity,yet little is known about the underlying mechanism.To examine this,we established a transient middle cerebral artery occlusion male mouse model.We found that physical exercise elevated brain Treg cells,thereby enhancing neurological recovery,reducing neuroinflammation,promoting myelin debris clearance,and accelerating white matter repair.Depletion of Treg cells caused a decrease in these positive effects of physical exercise.Mechanistically,the rise in osteopontin triggered by physical exercise is dampened when Treg cells are depleted.In addition,Treg-conditioned medium reduced oxygen-glucose deprivation/re-oxygenation-induced microglial inflammation and enhanced phagocytosis,which could be blocked by osteopontin antibodies.Importantly,although Treg infusion could mimic the protective effects of physical exercise,osteopontin blockade partially countered the effects of physical exercise and Treg cells.Finally,our sequencing data revealed a marked upregulation of C-X-C motif chemokine ligand 12(CXCL12)mRNA expression subsequent to physical exercise,which was confirmed at the protein level.Stimulation of Treg cells with stroke brain lysates increased C-X-C motif chemokine receptor 4(CXCR4)expression,indicating a potential role for the CXCL12-CXCR4 axis in recruiting Treg cells.These findings suggest that physical exercise promotes white matter repair after ischemic stroke by Treg cells.
文摘Background:The topic of this review is the study of the gut microbiota(GM),and the use of probiotics,especially in humans,as a new frontier in the field of prevention and health in general.The beneficial effects and functions performed by probiotics in the GM are increasingly at the centre of both scientific,medical,and pharmaceutical interest.It is now known that diet and probiotics can modify the GM,although in these situations there is a need for greater and more in-depth research regarding the methods and timing of treatment.However,the relationship between physical activity,GM,and probiotics is still largely unclear,as regards certain mechanisms between physical exercise and probiotics in humans.Discussion:In this study,we tried to demonstrate whether and how physical exercise was able to alter the composition of the microbiota and how probiotics can facilitate it.Therefore,alteration of the microbiota was considered in terms of both diversity and composition.Conclusions:The ones examined propose vastly different physical exercises,both in terms of timing and type of intervention itself,and the use of probiotics.

文摘Physical exercise is recognized as an effective intervention to improve mood,physical performance,and general well-being.It achieves these benefits through cellular and molecular mechanisms that promote the release of neuroprotective factors.Interestingly,reduced levels of physical exercise have been implicated in several central nervous system diseases,including ocular disorders.Emerging evidence has suggested that physical exercise levels are significantly lower in individuals with ocular diseases such as glaucoma,age-related macular degeneration,retinitis pigmentosa,and diabetic retinopathy.Physical exercise may have a neuroprotective effect on the retina.Therefore,the association between reduced physical exercise and ocular diseases may involve a bidirectional causal relationship whereby visual impairment leads to reduced physical exercise and decreased exercise exacerbates the development of ocular disease.In this review,we summarize the evidence linking physical exercise to eye disease and identify potential mediators of physical exercise-induced retinal neuroprotection.Finally,we discuss future directions for preclinical and clinical research in exercise and eye health.

文摘The health benefits of physical exercise are well established and have been observed in both human studies and rodent models[1],improving overall health and stress resilience.However,the underlying molecular mechanisms have not been comprehensively investigated.Previous studies have focused extensively on its neuromodulatory effects and have also identified multiple exercise-associated molecular substrates and blood-borne metabolites,including neurotrophic factors,monoamine neurotransmitters,neuroinflammatory cytokines,kynurenine,N-lactoylphenylalanine,and the ketone bodyβ-hydroxybutyrate[2].Notably,lactate,a common energy source derived from cellular glycolysis in response to intensive exercise,has recently been reported to exert antidepressant activity[3].However,a detailed mechanistic explanation is lacking.

文摘The prevalence of high blood pressure is on the rise among younger individuals,and recent findings have linked exercise to changes in the diversity and configuration of gut microbiota.However,specific modifications to one's diet,such as incorporating blueberries while engaging in physical activity,can also influence this association.To explore the effects of exercise and blueberry consumption on gut bacteria,we conducted an 8-week study involving healthy and hypertensive college students.Our microbiome analysis revealed slight shifts in gut bacteria composition in response to increased physical activity,with significant changes in the diversity of the g_[Eubacterium]_eligens_group observed in hypertensive college students who regularly consumed blueberries.Although exercise and blueberry supplementation had a negligible impact on the gut microbiota diversity of healthy college students,it significantly boosted the production of butyric acid bacteria in hypertensive young adults.These results suggest that the changes in gut bacteria variety and abundance brought about by blueberries may be tied to alterations in the body composition of patients with hypertension.This study aims to reveal the impact of blueberry on the hypertensive students from a unique perspective,suggesting the impact of taking blueberry while taking exercises.
文摘The mental health of adolescents is a priority for successful development.Physical activity(PA)and exercise can have effects on the mental health of adolescents.This review analysed the effect that physical exercise interventions can have on the mental health of healthy adolescents between 10 and 19 years of age.The search was carried out in four databases.PubMed,Web of Science,Scopus and SportDiscuss,were searched up to December 31,2022,following the general model.Eleven studies were selected,with a total sample of 23681 participants in 2435 studies published in the last 5 years involving healthy adolescents.The search process and review of the articles was performed by independent expert investigators.The risk-of-bias and the methodological quality were analysed using the Cochrane scale.The limited and heterogeneous studies conducted so far do not clearly establish the benefits of PA on adolescents’mental health.However,some PA interventions seem to improve subjective well-being,self-esteem,physical and mental well-being,anxiety,lifestyle,emotional intelligence,depressive mood,and perceived benefit and confidence in healthy adolescents.It is important to design an effective and appropriate physical exercise programme that can be implemented for adolescents to achieve significant effects on their mental health.Studies that did not implement an appropriate exercise program with improvements in adolescent physical fitness showed no changes in psychological variables.Further research is needed to clearly establish that exercise programmes have positive effects on mental health in healthy adolescents.
文摘Subjective well-being is a key indicator of quality of life and a crucial factor for successful aging among older adults.However,few studies have explored the subjective well-being among older adults from the perspective of digital literacy.Therefore,this study explores the relationship between digital literacy and subjective well-being using data on 4270 older adults from the 2020 China Family Panel Studies(CFPS)dataset.PROCESS mediation analysis results indicated digital literacy is associated with higher subjective well-being among the older adults.Digital literacy was associated with the frequency of physical exercise and consumption.Moreover,Digital literacy can also enhance the subjective well-being among older adults by increasing the frequency of physical exercise,and consumption,and a chain mediator subjective well-being.These findings align with the theoretical framework of digital health literacy.Theory which posits that health information obtained through digital literacy can help older adults better engage in healthy lifestyles,thereby enhancing their quality of life.These findings hold significant practical implications for enhancing the subjective well-being among older adults and advancing the development of successful aging.
文摘Inflammatory bowel disease(IBD),comprising Crohn’s disease and ulcerative colitis,represents the two predominant clinical entities within this spectrum of gastrointestinal disorders.Current evidence indicates that the etiology of IBD is multifactorial,involving a complex interplay between host genetic susceptibility and environmental determinants.In recent years,non-pharmacological strategies such as physical exercise and vagus nerve stimulation have gained increasing attention as adjunctive therapeutic approaches.Vagus nerve stimulation has emerged as a promising therapeutic modality,particularly in conditions characterized by autonomic dysfunction and diminished vagal tone.Conversely,vagotomy,by disrupting vagal control,abolishes parasympathetic reflexes and may potentiate inflammatory responses and exacerbate IBD symptomatology under stress conditions.Physical exercise has likewise been investigated as a non-pharmacological intervention in Crohn’s disease and ulcerative colitis.Although the precise mechanisms remain to be fully elucidated,accumulating evidence suggests that skeletal muscle contractions promote the secretion of myokines,with recognized anti-inflammatory properties.These myokines act on the intestinal microenvironment,conferring protection against malignant transformation and modulating the composition and function of the gut microbiota.In this review,we critically examine the interplay between physical exercise,vagus nerve stimulation,and vagotomy in the pathophysiology and management of IBD,with particular emphasis on their immunomodulatory and therapeutic potential.
文摘In recent years,insufficient physical activity has coincided with suboptimal health among university students.Drawing on the Suboptimal Health Status(SHS)framework,this study surveyed 314 students from multiple provinces/municipalities in China.Physical activity was assessed with a physical activity level scale,and health status with the Sub-Health Measurement Scale Version 1.0(SHMS V1.0).Correlation and multiple regression analyses were used to test associations.Physical exercise was positively associated with overall health(r=0.515,p<0.001)and,after adjusting for sex,only-child status,and place of origin,remained a signifi cant predictor of better health(β=0.515,t=10.512,p<0.001).Sex was associated with exercise level,whereas other demographic variables showed no signifi cant eff ects on health status.These fi ndings suggest that promoting moderate-to-vigorous physical activity and campus sport participation may improve students’physiological,psychological,and social adaptation,providing practical guidance for health promotion and exercise prescription in higher education.

文摘Physical activity,moderate aerobic or resistance exercise are well established to offer health benefits and promote healthy aging and longevity.^(1)In contrast,lack of exercise contributes to adverse events,especially in some patients with organ failure.^(2)Therefore,“exercise pills”and“exercise mimetics”have attracted growing interest because of their potential to induce exercise-related health effects despite physical exercise not being performed.^(3)Robust studies over the past decade have identified many natural biomacromolecules,such as peptide,non-coding Ribonucleic Acid(RNAs),and lipids,that are induced by exercise.^(4-6)These molecules trigger physiological adaptations,including promotion of cardiomyocyte proliferation,anti-apoptotic capacity,and healthy tissue growth.7However,identifying or designing an exercise pill that mimics the extensive benefits of exercise is still challenging.
文摘Objective:To observe the effect of acupuncture combined with the Thirteen-posture Tai Chi exercise prescription on the rehabilitation of cervical radiculopathy(CR).Methods:A total of 159 patients diagnosed with CR were enrolled in a prospective study.They were randomly divided into an acupuncture group,an exercise group,and a combined group using the random number table method,with 53 cases in each group.All three groups received routine Western rehabilitation training.In addition,the acupuncture group was treated with“Si Tian Xue”[four points with“Tian”in their names,including Tianyou(TE16),Tianchuang(SI16),Tianrong(SI17),and Tianding(LI17)]acupuncture.The exercise group practiced according to the Thirteenposture Tai Chi exercise prescription.The combined group received“Si Tian Xue”acupuncture combined with the Thirteen-posture Tai Chi exercise prescription.All interventions lasted for 12 weeks in three groups.The neck disability index(NDI)and visual analog scale(VAS)scores were compared among the three groups before treatment and after 6 and 12 weeks of treatment.Before treatment and after 12-week treatment,the range of motion(ROM)of cervical in left rotation,right rotation,extension,and flexion,as well as the mean power frequency(MPF)of surface electromyography(sEMG)signals of the erector spinae and trapezius,the average blood flow velocity of the vertebral and basilar arteries,and the short-form 36-item health survey(SF-36)score was compared among the three groups.Results:After 6 and 12 weeks of treatment,the NDI and VAS scores of the three groups were significantly lower than those before treatment(P<0.05),and the NDI and VAS scores of the combined group were significantly lower than those of the acupuncture group and the exercise group at the same time points(P<0.05).After treatment,the cervical ROM in left rotation,right rotation,extension,and flexion in the three groups was significantly higher than that before treatment(P<0.05),and the combined group was significantly higher than the acupuncture group and the exercise group(P<0.05).After treatment,the MPF of the erector spinae and trapezius and the average blood flow velocity of the vertebral and basilar arteries in the three groups were significantly higher than those before treatment(P<0.05),and the combined group was significantly higher than the acupuncture group and the exercise group(P<0.05).After treatment,the SF-36 score of the three groups was significantly higher than that before treatment(P<0.05),and it was significantly higher in the combined group than in the acupuncture group and the exercise group(P<0.05).Conclusion:Compared to“Si Tian Xue”acupuncture or the Thirteen-posture Tai Chi exercise prescription alone,the combination of the two can more effectively improve cervical function and microcirculation,relieve pain,and improve the quality of life in patients with CR.
文摘Exercise can enhance motivation to change lifestyle behaviors,improve aerobic fitness,improve physical function,control fatigue,and enhance quality of life.Studies have demonstrated the benefits to be gained from physical exercise,highlighting the importance of popularizing the concept of physical exercise for individuals and making professional exercise-treatment programs available to patients with cancer.However,the correlation between physical exercise and carcinogenesis is easily overlooked,and exercise interventions are not routinely provided to patients with cancer,especially those with advanced cancer.In this article,we present a literature review of the effects of exercise on cancer development and progression and give recent evidence for the type of exercise best suited for different types of cancer and in different disease stages.Moreover,the molecular mechanisms about regulating metabolism and systemic immune function in cancer are summarized and discussed.In conclusion,physical exercise should be considered as an important intervention for preventing and treating cancer and its complications.

文摘AIM: To clarify the association between physical activity and gastroesophageal reflux disease (GERD) in nonobese and obese people. METHODS: A Swedish population-based cross-sectional survey was conducted. Participants aged 40-79 years were randomly selected from the Swedish Registry of the Total Population. Data on physical activity, GERD, body mass index (BMI) and the covariates age, gender, comorbidity, education, sleeping problems, and tobacco smoking were obtained using validated questionnaires. GERD was self-reported and defined as heartburn or regurgitation at least once weekly, and having at least moderate problems from such symptoms. Frequency of physical activity was categorized into three groups: (1) "high" (several times/week); (2) "intermediate" (approximately once weekly); and (3) "low" (1-3 times/mo or less). Analyses were stratified for participants with "normal weight" (BMI < 25 kg/m 2 ), "overweight" (BMI 25 to ≤ 30 kg/m 2 ) and "obese" (BMI > 30 kg/m 2 ). Multivariate logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for potential confounding by covariates. RESULTS: Of 6969 eligible and randomly selected individuals, 4910 (70.5%) participated. High frequency of physical activity was reported by 2463 (50%) participants, GERD was identified in 472 (10%) participants, and obesity was found in 680 (14%). There were 226 (5%) individuals with missing information about BMI. Normal weight, overweight and obese participants were similar regarding distribution of gender and tobacco smoking status, while obese participants were on average slightly older, had fewer years of education, more comorbidity, slightly more sleeping problems, lower frequency of physical activity, and higher occurrence of GERD. Among the 2146 normal-weight participants, crude point estimates indicated a decreased risk of GERD among individuals with high frequency of physical activity (OR: 0.59, 95% CI: 0.39-0.89), compared to low frequency of physical activity. However, after adjustment for potential confounding factors, neither intermediate (OR: 1.30, 95% CI: 0.75-2.26) nor high (OR: 0.99, 95% CI: 0.62-1.60) frequency of physical activity was followed by decreased risk of GERD. Sleeping problems and high comorbidity were identified as potential confounders. Among the 1859 overweight participants, crude point estimates indicated no increased or decreased risk of GERD among individuals with intermediate or high frequency of physical activity, compared to low frequency. After adjustment for confounding, neither intermediate (OR: 0.75, 95% CI: 0.46-1.22) nor high frequency of physical activity were followed by increased or decreased risk of GERD compared to low frequency among nonobese participants. Sleeping problems and high comorbidity were identified as potential confounders for overweight participants. In obese individuals, crude ORs were similar to the adjusted ORs and no particular confounding factors were identified. Intermediate frequency of physical activity was associated with a decreased occurrence of GERD compared to low frequency of physical activity (adjusted OR: 0.41, 95% CI: 0.22-0.77). CONCLUSION: Intermediate frequency of physical activity might decrease the risk of GERD among obese individuals, while no influence of physical activity on GERD was found in non-obese people.

文摘Psychological depression is drawing accumulating attention nowadays, due to the skyrocketing incidence worldwide and the enormous burdens it incurs. Physical exercise has been long recog- nized for its therapeutic effects on depressive disorders, although knowledge of the underlying mechanisms remains limited. Suppressed hippocampal neurogenesis in adult brains has been regarded, at least partly, contributive to depression, whereas physical exercise that restores neuro- genesis accordingly exerts the anti-depressive action. Several recent publications have suggested the potential role of adiponectin, a protein hormone secreted by peripheral mature adipocytes, in mediating physical exercise-triggered enhancement of hippocampal neurogenesis and alleviation of depression. Here, we briefly review these novel findings and discuss the possibility of counter- acting depression by modulating adiponectin signaling in the hippocampus with interventions including physical exercise and administration of pharmacological agents.

文摘Objective:Physical exercise,a common non-drug intervention,is an important strategy in cancer treatment,including hepatocellular carcinoma(HCC).However,the mechanism remains largely unknown.Due to the importance of hypoxia and cancer stemness in the development of HCC,the present study investigated whether the anti-HCC effect of physical exercise is related to its suppression on hypoxia and cancer stemness.Methods:A physical exercise intervention of swimming(30 min/d,5 d/week,for 4 weeks)was administered to BALB/c nude mice bearing subcutaneous human HCC tumor.The anti-HCC effect of swimming was assessed in vivo by tumor weight monitoring,hematoxylin and eosin(HE)staining,and immunohistochemistry(IHC)detection of proliferating cell nuclear antigen(PCNA)and Ki67.The expression of stemness transcription factors,including Nanog homeobox(NANOG),octamer-binding transcription factor 4(OCT-4),v-Myc avian myelocytomatosis viral oncogene homolog(C-MYC)and hypoxia-inducible factor-1a(HIF-1a),was detected using real-time reverse transcription polymerase chain reaction.A hypoxia probe was used to explore the intratumoral hypoxia status.Western blot was used to detect the expression of HIF-1a and proteins related to protein kinase B(Akt)/glycogen synthase kinase-3β(GSK-3β)/β-catenin signaling pathway.The IHC analysis of platelet endothelial cell adhesion molecule-1(CD31),and the immunofluorescence co-location of CD31 and desmin were used to analyze tumor blood perfusion.SMMC-7721 cells were treated with nude mice serum.The inhibition effect on cancer stemness in vitro was detected using suspension sphere experiments and the expression of stemness transcription factors.The hypoxia status was inferred by measuring the protein and mRNA levels of HIF-1a.Further,the expression of proteins related to Akt/GSK-3β/β-catenin signaling pathway was detected.Results:Swimming significantly reduced the body weight and tumor weight in nude mice bearing HCC tumor.HE staining and IHC results showed a lower necrotic area ratio as well as fewer PCNA or Ki67 positive cells in mice receiving the swimming intervention.Swimming potently alleviated the intratumoral hypoxia,attenuated the cancer stemness,and inhibited the Akt/GSK-3β/β-catenin signaling pathway.Additionally,the desmin+/CD31+ratio,rather than the number of CD31+vessels,was significantly increased in swimming-treated mice.In vitro experiments showed that treating cells with the serum from the swimming intervention mice significantly reduced the formation of SMMC-7721 cell suspension sphere,as well as the m RNA expression level of stemness transcription factors.Consistent with the in vivo results,HIF-1a and Akt/GSK-3β/β-catenin signaling pathway were also inhibited in cells treated with serum from swimming group.Conclusion:Swimming alleviated hypoxia and attenuated cancer stemness in HCC,through suppression of the Akt/GSK-3β/β-catenin signaling pathway.The alleviation of intratumoral hypoxia was related to the increase in blood perfusion in the tumor.

文摘The many important benefits of physical exercise also encompass maintenance or improvement of cognitive functions. Among the variousmechanisms underlying the association between physical exercise and brain health, recent evidence attests that neurotrophin receptor signalingmay have an important role, because the activation of this pathway leads to growth and differentiation of new neurons and synapses, supportsaxonal and dendritic growth, fosters synaptic plasticity, and preserves survival of existing neurons. In this review of published evidence, we highlightthat a positive relationship exists between physical exercise and circulating brain-derived neurotrophic factor levels and that the postexercisevariation of this molecule is associated with improvement of neurocognitive functioning. Less clear evidence has instead been published forother neurotrophins, such as nerve growth factor, neurotrophin-3, and neurotrophin-4. Overall, promotion of adequate volumes and intensities ofphysical exercise (i.e., approximately 3 months of moderate-intensity aerobic exercise, with 2—3 sessions/week lasting not less than 30 min)may hence be regarded as an inexpensive and safe strategy for boosting brain-derived neurotrophic factor release, thus preserving or restoringcognitive functions.
