BACKGROUND:Resveratrol is a naturally occurring polyphenolic compound in plants,recognized for its anti-inflammatory,antioxidant,and antiproliferative properties.Its role in preventing and treating various chronic diseases has been extensively documented.Recent evidence suggests that resveratrol may help delay exercise-induced fatigue,although the underlying mechanisms remain to be systematically elucidated.OBJECTIVE:To explore the possible role and mechanism of resveratrol in delaying exercise-induced fatigue,based on the mechanism of exercise-induced fatigue,in order to provide a theoretical basis for the research and application of resveratrol in the field of sports nutrition.METHODS:Chinese and English search terms were"resveratrol,exercise-induced fatigue,oxidative stress,inflammation,energy substance,muscle injury,mitochondrial quality,neurotransmitter."CNKI,WanFang Data,and PubMed were searched for relevant research literature published from January,1992 to August 2024.A total of 73 core related articles were obtained according to inclusion and exclusion criteria.RESULTS AND CONCLUSION:(1)Resveratrol is a naturally occurring polyphenolic compound commonly found in plants such as grape skins,berries,and peanuts.It exhibits multiple biological activities,including antioxidant,anti-aging,anticancer,and anti-inflammatory properties.Resveratrol shows potential for preventing and treating various chronic diseases and is also thought to delay the onset of exercise-induced fatigue.(2)Exercise-induced fatigue is a non-pathological fatigue phenomenon with a complex mechanism.It is related to peripheral mechanisms such as the depletion of energy substrates,the accumulation of metabolic by-products,inflammation,and oxidative stress,as well as central mechanisms,including protective inhibition by the central nervous system and neurotransmitter imbalances.(3)Resveratrol activates the kelch-like epichlorohydrin-associated protein 1/nuclear factor erythroid 2-related factor 2 pathway,upregulating antioxidant-related genes such as catalase and superoxide dismutase while downregulating genes such as malondialdehyde and 4-hydroxy-2-nonenal,ultimately reducing oxidative stress.Resveratrol also activates silent information regulator 1,inhibits the nuclear factor-kappaB and nucleotide-binding oligomerization domain-like receptor thermal protein domain associated protein 3 inflammasome pathways,and downregulates pro-inflammatory cytokines such as tumor necrosis factor-α,interleukin-6,and interleukin-1β,alleviating inflammation.Additionally,resveratrol increases short-chain fatty acid production by the gut microbiota,elevates the lactate/pyruvate ratio in the liver to promote gluconeogenesis,and enhances fatty acid oxidation,thereby improving energy substrate utilization.Furthermore,through silent information regulator 1/peroxisome proliferator-activated receptor-y coactivator-1α/nuclear respiratory factor 1 activation,resveratrol enhances mitochondrial biogenesis in skeletal muscle,promotes mitochondrial fusion and fission for optimal dynamics,and activates mitophagy,improving mitochondrial quality.It also diminishes plasma tryptophan levels,decreases excessive serotonin secretion in the brain,increases dopamine release,and reduces glutamate toxicity,helping regulate neurotransmitter imbalances.Moreover,resveratrol lowers plasma lactate and ammonia levels,promoting metabolic by-product clearance,thereby delaying the onset of exercise-induced fatigue.(4)While current evidence indicates that resveratrol is effective in delaying exercise-induced fatigue,the optimal dose,timing,and duration of supplementation remain uncertain.Moreover,the interactions between resveratrol and other supplements,such as caffeine and vitamins,remain underexplored.Thus,future research should focus on optimizing supplementation strategies for resveratrol.

Objective To investigate if Shikonin(SKI)can induce ferroptosis via the ROS/JNK pathway to inhibit the malignant behavior of pancreatic cancer.Methods Human pancreatic cancer PANC-1 or BxPC-3 cells were selected.Drug efficacy experiments were established with a blank control group(Con group)and low,medium,and high dose SKI groups(2,4,8 μmol/L).JNK-related mechanism experiments were categorized into a blank control group(Con group),SKI group,and SKI+JNK inhibitor group(SKI+SP600125 group).ROS-related mechanism experiments were divided into a blank control group(Con group),SKI group,and SKI+ROS scavenger group(SKI+NAC group).Cell viability was assessed using the CCK-8 method to calculate IC50;Transwell experiments evaluated cell migration and invasion capabilities;the C11 BODIPY 581/591 probe was utilized for flow cytometry to detect lipid peroxidation levels,while the FerroOrange fluorescent probe measured ferrous ion levels;ROS levels were determined using a ROS detection kit;the Western blot method identified ferroptosis-related key proteins(SLC7A11,GPX4),apoptosis-related proteins(Caspase3,PARP),and JNK pathway proteins(JNK,p-JNK);an in vivo xenograft tumor model was employed to assess tumor proliferation.Results SKI treatment significantly and dose-dependently inhibited PANC-1 cell viability(IC50:6.04 μmol/L,P<0.0001)and BxPC-3 cell viability(IC50:12.27 μmol/L,P<0.0001),and significantly reduced migrating and invasive cell numbers(P<0.0001),with migration cell numbers dropping to about 30%of the control group at 8 μmol/L SKI treatment(P<0.0001).Mechanistically,SKI induced increased intracellular lipid peroxidation,Fe2+accumulation,and significant ROS production(P<0.0001),significantly downregulated SLC7A11 and GPX4 protein expression(GPX4 protein expression reduced to 40%of that in the control group,P<0.0001),and activated JNK phosphorylation(p-JNK/JNK ratio increased to 2.8-fold,P<0.0001).Pretreatment with the JNK-specific inhibitor SP600125 or ROS scavenger NAC effectively reversed SKI's inhibition of cell viability and downregulation of SLC7A11/GPX4 protein(all P<0.01).SKI also inhibited pancreatic cancer tumor cell proliferation in vivo(P<0.0001).Conclusion SKI induces ferroptosis by activating the ROS/JNK pathway,thereby inhibiting pancreatic cancer proliferation,migration,and invasion.

BACKGROUND:A large number of studies have investigated the effects of whole body vibration training at different frequencies on muscle strength,but less is reported on the differences in the efficacy of vibration training at different frequencies on patellar tendinopathy. OBJECTIVE:To explore the effect of eccentric training of quadriceps combined with different frequency of whole body vibration training on patellar tendinopathy. METHODS:From April to June 2022,48 patients with patellar tendinopathy were recruited from Wuhan Sports University and randomly divided into eccentric training group(n=12),30 Hz group(n=12),40 Hz group(n=12),and 50 Hz group(n=12).The eccentric training group only completed eccentric training of the quadriceps.The 30 Hz,40 Hz and 50 Hz groups performed the whole body vibration training with the amplitude of 2 mm and frequencies of 30 Hz,40 Hz and 50 Hz respectively on the basis of the eccentric training of the quadriceps.The intervention lasted for 8 weeks,three times a week.Before and after the intervention,the patients'surface electromyography signals of the quadriceps,kinematics and dynamics data of knee joint at the time of landing in deep jump and the time of peak vertical ground reaction,Visual Analogue Scale score,Victorian Institute of Sports Assessment-Patellar score were evaluated. RESULTS AND CONCLUSION:After 8 weeks of intervention,compared with the eccentric training group,the median frequency of the lateral and medial femoris muscles were significantly higher in the 40 Hz and 50 Hz groups(P＜0.05).At the time of landing,the knee joint flexion angle and external rotation moment in the 40 Hz and 50 Hz groups were significantly lower than those in the eccentric training group(P＜0.05),while the knee joint flexion angle in the 50 Hz group was significantly lower than that in the 30 Hz group(P＜0.05).At the peak moment of vertical ground reaction,the knee extension torque in the 40 Hz group was significantly lower than that in the eccectric training group(P＜0.05);the knee flexion angle and knee extension torque in the 50 Hz group were significantly lower than those in the eccentric training group(P＜0.05).The Visual Analogue Scale scores in the 50 Hz and 40 Hz groups were significantly lower than those in the eccentric training group(P＜0.05).The Victorian Institute of Sports Assessment-Patellar score in the 50 Hz group was significantly higher than that in the eccentric training group and 30 Hz group(P＜0.05).To conclude,eccentric training of the quadriceps combined with 50 Hz whole body vibration training can significantly improve quadriceps'strength,endurance and activation rate of the vastus lateralis muscle,reduce the pain of knee joint,and improve the function of the knee joint in patients with patellar tendinopathy.

BACKGROUND:Mesenchymal stem cells are pluripotent stromal cells isolated from a variety of tissues,which can differentiate into osteoblasts under certain conditions.Photobiomodulation,as an external stimulus,can promote osteogenic differentiation combined with other inducers or alone,providing new ideas for solving a series of bone diseases. OBJECTIVE:To review the relevant literature and mechanisms of photobiomodulation-induced osteogenic differentiation of mesenchymal stem cells,which will lay a theoretical foundation for bone tissue engineering using mesenchymal stem cells as seed cells and may offer some suggestions for future studies. METHODS:Relevant articles were searched on CNKI,PubMed and Wed of Science databases with Chinese search terms of"photobiomodulation,low power laser,low level laser,light-emitting diode,mesenchymal stem cells,osteogenic differentiation,biomaterials"and English search terms of"photobiomodulation,low level laser(light),light-emitting diode(LED),mesenchymal stem cell,osteogenic differentiation,biomaterials".Finally,88 articles were included for analysis. RESULTS AND CONCLUSION:(1)Photobiomodulation represented by low level laser and diode laser has a positive effect on promoting the proliferation and differentiation of mesenchymal stem cells.(2)Photobiomodulation can induce osteogenic differentiation of mesenchymal stem cells,whose feasibility has been verified in cell and animal experiments.On one hand,photobiomodulation can promote the expansion and differentiation of stem cells in vitro by activating related signaling pathways and up-regulating the expression of osteogenic molecules.On the other hand,photobiomodulation can improve the survival rate of stem cells in vivo,promote homing effect and shorten the healing time of bone defects after stem cells are injected into the body.However,photobiomodulation has a biphasic dose effect,whose laser parameters,experimental environment,cell type and other factors in various studies are different,making the research results lack consistency and difficult to apply in the clinic.(3)Combined with biological materials,other physical factors and drugs,photobiomodulation can also accelerate osteogenic differentiation.(4)In conclusion,photobiomodulation has been used increasingly widely in the medical field with its advantages of non-invasive,efficient and less-side reactions,and its role in bone tissue engineering has gradually become prominent,which provides a new method for the treatment of bone defects and related diseases.Further exploration should be focused on the standardized treatment parameters of photobiomodulation.

ObjectiveTo analyze the occurrence of sport injury in Paralympic athletes during the Summer or Winter Paralympic Games, as well as the risk factors for sport injuries and possible interventions. MethodsThe literatures related to sport injuries of Paralympic athletes were searched in PubMed, Web of Science, EBSCO and CNKI from January, 2013 to July, 2022, and a scoping review of the retrieved literature was performed. ResultsFinally, eight English articles from China, Sweden, South Africa, Poland and the United States were included, involving 4 769 atheletes. They included one interview study, five survey studies, one retrospective study and one prospective cohort study, which were mainly from journals in the fields of sport medicine, adaptive sport and sport science, and the publication date was mainly from 2016 to 2022. The types of disability of Paralympic athletes mainly involved physical disability (upper and lower limb amputation, cerebral palsy, spinal cord injury, poliomyelitis, dysplasia and neuromuscular dystrophy, central nervous system injury, myelomeningocele, etc.), intellectual disability and visual disability. The incidence of sport injury was high in Paralympic athletes, and most of the injury occured during competitions. Acute injury, chronic overuse injury and chronic to acute injury were the three most common types of injury. Sports injuries mainly involved head and neck, upper limbs (shoulders, upper arms/forearms, elbows, wrists and fingers), trunk (abdomen, back and waist), and lower limbs (hips/groin, thighs, knees, calves, ankles and toes). Risk factors for sport injuries in Paralympic athletes mainly included previous injury history, illness, fatigue and decreased physical strength, spasticity and muscle weakness; emotional states of inattention or distraction, excessive anxiety or excitement; improper exercise training methods, lack of knowledge related to sport training and injury prevention, and motor skill deficiencies; weather, competition venues, sport facilities, use of equipment and assistive devices, age factors, etc. Injuries of Paralympic athletes could be prevented by providing rehabilitation services for Paralympic athletes, optimizing training design, conducting collective training for coaches and athletes on various types of injuries, conducting research related to sport injuries of disabled athletes, formulating prevention programs and strategies, improving the physical fitness and sport skills of Paralympic athletes, improving emergency treatment techniques for injuries, and strengthening coordination and governance structures between sport medicine and rehabilitation therapists. ConclusionThe incidence of sport injury is high in Paralympic athletes. Chronic overuse injury is the most common injury type, and the injuries most involve head, neck and upper extremities. The risk factors for sport injuries of Paralympic athletes mainly involve physical function, psychological, activities and participation, environment and other factors. The main intervention strategies include providing emergency treatment intervention and monitoring services, sport medicine treatment and rehabilitation, guidance and specialized support, and health education on sport injury prevention.

ObjectiveTo evaluate the main structural and content features of four instruments for motor function and motor ability assessment and their psychometric properties for children and adolescents with disabilities, based on International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY). MethodsPubMed, Medline and Web of Science databases were searched for literature on motor function and motor ability assessment for children and adolescents with disabilities published from establishment to May, 2023. The main structural and content characteristics of the tools were analyzed using ICF-CY, and the quality of measurement tools was assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). ResultsNine papers were eventually included, and four assessment tools were identified, including Gross Motor Function Measure-88 (GMFM-88), Peabody Developmental Motor Scales second edition (PDMS-2), Bruininks-Oseretsky Test of Motor Proficiency second edition (BOT-2), and Movement Assessment Battery for Children second edition (MABC-2). The GMFM-88 consisted of 88 items in five dimensions: zone A (lying and rolling), zone B (sitting), zone C (crawling and kneeling), zone D (standing), and zone E (walking and running and jumping); it involved joint movement function (b710), random movement control function (b760), etc., in body function; and the change of basic body posture to maintain a body posture (d410) and maintain a body posture (d415) in activity and participation, with good to excellent levels of internal consistency reliability, test-retest reliability, content validity, and structural validity. The PDMS-2 consisted of six subtests, including reflexes, posture, movement, physical manipulation, grasping and visuomotor integration, with a total of 249 items; it involved memory function (b144) and joint mobility function (b710) in body function; as well as looking (d110) and imitation (d130) in activity and participation; with good psychometric properties in terms of internal consistency reliability, test-retest reliability, content validity, structural validity, and hypothesis testing and cross-cultural feasibility. There are two versions of BOT-2: long form and short form. The long form consisted of eight subtests with 53 items, involving joint mobility function (b710) and joint stability function (b715) in body function; as well as imitation (d130) and learned calculation (d150) in activity and participation; it achieved excellent levels of psychometric properties in terms of internal consistency reliability, content validity, and structural validity, and good level in reliability and test-retest reliability. MABC-2 consisted of two parts: an activity ability test and a checklist with 30 items; it involved joint mobility function (b710), joint stability function (b715), etc., in body function; as well as fine-hand use (d440), hand and arm use (d445) in activity and participation; with good psychometric properties such as reliability, content validity, and structural validity. ConclusionThis systematic review analyzed the main structural and content characteristics of four types of measurement tools for assessing motor function and motor ability in children and adolescents with disabilities based on the ICF-CY, and evaluated the quality of psychometric properties (internal consistency reliability, test-retest reliability, content validity, structural validity, and cross-cultural consistency, etc.) of the four types of measurement tools using the COSMIN criteria. For the structure and content, PDMS-2 appears the broadest content, and measures fine hand movements, dynamic and static balance, along with the BOT-2 and MABC-2. GMFM-88 focuses more on gross motor functions such as postural control. Four instruments show high internal consistency reliability, test-retest reliability, content validity and structural validity, while the BOT-2 and PDMS-2 show better reliability. To ensure the reliability and validity of the measures, rehabilitation workers and educators need to receive standardized training and qualification before using the standardized instruments for motor function and motor ability for children with disabilities. With norm-referenced measures, the results need to be converted to standard scores.
