OBJECTIVE:This paper collects relevant literature on blood flow restriction training combined with resistance training,and analyzes the different effects of blood flow restriction training combined with resistance training on athletes'muscle-related indexes and specialized abilities in accordance with the paradigm of systematic evaluation and Meta-analysis,aiming to provide data support for athletes to utilize blood flow restriction training in their training practices. METHODS:Chinese and foreign databases(CNKI,WanFang,PubMed,Web of Science,SPORTDiscus)were searched to collect randomized controlled trials on the effects of blood flow restriction training combined with resistance training on limb circumference,muscle mass,muscle strength,and specialized ability of college athletes from January 1st,2000 to October 12th,2023.At least two researchers evaluated the quality of the included literature using the Cochrane Collaboration risk of bias assessment tools and criteria.Heterogeneity tests,data merging,subgroup analyses,forest plotting,and sensitivity analyses were performed using RevMan 5.4,and funnel plots with publication bias evaluation and sensitivity analyses were performed.The evaluation indexes were limb circumference,muscle thickness,muscle strength and specialized ability,and subgroup analyses were performed for different specialized athletic abilities. RESULTS:(1)A total of 18 randomized controlled trials with 403 subjects were included,and according to the Cochrane Collaboration's risk of bias assessment tool,the quality of literature in the included literature was grade A in 16 articles and grade B in 2 articles.(2)Comparing the effects of blood flow restriction training combined with resistance training and resistance training,there was no significant difference between the two groups in terms of limb circumference[standardized mean difference(SMD)=0.03,95%confidence interval:-0.16-0.21,P=0.78],and a significant difference between the two groups in terms of muscle thickness(SMD=0.14,95%CI:0.01-0.27,P=0.03)and muscle strength(SMD=0.37,95%CI:0.14-0.60,P=0.001).(3)Subgroup analyses of the indicators of specialized capacity indicated that there was high heterogeneity in the analyzed results of distance metrics(I2=73%)and time metrics(I2=55%),which was analyzed as a possible reason due to the differences in testing methods and assessment of metrics'significance in the studies;there was no heterogeneity(I2=0%)in the analyzed results of power metrics;blood flow restriction training combined with resistance training had a significant effect on distance metrics(P<0.01).(4)The results of the combined effect showed the effect of blood flow restriction training combined with resistance training vs.resistance training for specialized ability(P=0.41),suggesting that there is no significant effect of different training methods on specialized ability. CONCLUSION:Both blood flow restriction training combined with resistance training and resistance training can promote muscle thickness,muscle strength and specialized ability in college athletes.Meanwhile,blood flow restriction training combined with resistance training has a more significant effect on muscle thickness,muscle strength and some specialized abilities compared with resistance training.Therefore,blood flow restriction training can be scientifically and rationally integrated into specialized training,so as to achieve a better training effect by integrating the differentiated physiological stimuli to the muscles.However,due to the small number of included studies and other possible limitations,more high-quality,multi-sport type and sex randomized trials need to be included in the future to confirm this.

Objective:To investigate the disease burden, clinical characteristics and independent risk factors affecting in-hospital outcomes of children with congenital heart disease (CHD) combined with heart failure (HF) in China.Methods:(1) Descriptive study: based on the global burden of disease study 2021, available data on children under 15 years of age with CHD and HF in China from 1990 to 2021 were collected. The prevalence and trends in different age subgroups (<1 year, 1-<2 years, 2-<5 years, 5-<10 years, 10-<15 years) were analyzed, and the annual percentage change (EAPC) was estimated using linear regression. (2) Retrospective cohort study: a total of 1 062 children with CHD and HF from a multicenter study on pediatric HF in China were included. The children were divided into two groups:<2 years group and 2-<18 years group. Data on demographics, clinical features, diagnosis, treatments, and in-hospital outcomes were analyzed. Mann-Whitney U test and chi-square test were used for group comparisons.Multivariable Logistic regression was applied to identify factors influencing outcomes (in-hospital mortality and adverse cardiovascular events). Results:(1) From 1990 to 2021, the number of children with CHD and HF in China increased from 333 000 (95% uncertainty interval ( UI) 271 000-405 000) to 368 000 (95% UI 296 000-459 000), a growth of 10.8% (95% UI 5.0%-16.6%). Concurrently the prevalence rate increased from 104.5 (95% UI 85.1-127.3) per 100 000 to 142.0 (95% UI 114.0-176.8) per 100 000, a growth of 35.9% (95% UI 28.7%-43.0%), with an EAPC of 1.5% (95% CI 1.2%-1.8%). Although the number of cases in the<1 year and 1-<2 years groups decreased by 41.0% and 25.6%, respectively, the prevalence in all age groups showed an upward trend:<1 year EAPC 0.6% (95% CI 0.5%-0.7%); 1-<2 years EAPC 0.9% (95% CI 0.8%-1.0%); 2-<5 years EAPC 1.2% (95% CI 1.0%-1.4%); 5-<10 years EAPC 1.5% (95% CI 1.2%-1.8%); 10-<15 years EAPC 2.1% (95% CI 1.9%-2.3%). (2) The multicenter study revealed that among 1 062 hospitalized children, 528 (49.7%) were male and 534 (50.3%) were female, with the age at admission of 5.4 (2.2,18.2) months. The majority of the children (77.9%, 827/1 062) were under 2 years of age, whereas 22.1% (235/1 062) were aged between 2-<18 years. Children with complex congenital heart defects accounted for the highest proportion (48.6%, 516/1 062), while those with isolated CHD made up 31.5% (335/1 062). Statistically significant differences were observed in several variables in demographics, clinical features, diagnosis, treatments, and outcomes between the two age groups (all P<0.05). The use of renin-angiotensin-aldosterone system inhibitors (41.1%, 436/1 062) and beta-blockers (8.7%, 92/1 062) was lower in hospitalized children with CHD and HF. Logistic regression identified complex CHD ( OR=7.73, 95% CI 2.24-26.63; OR=3.17, 95% CI 1.92-5.23), pulmonary hyperperfusion ( OR=2.15, 95% CI 1.01-4.18; OR=2.00, 95% CI 1.35-2.97), left ventricular ejection fraction<55% ( OR=2.13, 95% CI 1.08-4.21; OR=2.80, 95% CI 1.45-5.56), arterial oxygen partial pressure ( OR=0.99, 95% CI 0.98-0.99; OR=0.99, 95% CI 0.98-0.99), and serum calcium levels ( OR=0.31, 95% CI 0.17-0.58; OR=0.42, 95% CI 0.28-0.62) as independent risk factors for in-hospital mortality and cardiovascular events. Conclusions:The disease burden of CHD combined with HF in China has shown a continuous upward trend from 1990 to 2021, with higher growth rates in older age groups. Complex CHD, pulmonary hyperperfusion, left ventricular ejection fraction <55%, arterial oxygen partial pressure, and serum calcium concentration are independent risk factors for in-hospital mortality and cardiovascular events.

BACKGROUND:The Yi people have used Sambucus adnata Wall to treat fractures,bruises,arthritis,etc.The author's group found that the active site aqueous extract(SAW-A)and dichloromethane extract(SAW-B)can promote fracture healing by promoting the expression of genes related to osteoblast proliferation,differentiation and maturation,differentiation and maturation.However,the therapeutic effect of methanol extract(SAW-C)at its active site on osteoarthritis is unclear. OBJECTIVE:To investigate the therapeutic effect of Sambucus adnata Wall extract on osteoarthritis,and to identify the effective targets of Sambucus adnata Wall extract in the treatment of osteoarthritis by network pharmacology technology. METHODS:A rat osteoarthritis model was replicated by anterior cruciate ligamentectomy and model rats were then treated with methanol extract of Sambucus adnata Wall by gavage for 21 days.On the 21st day after modeling,the knee joint of rats was detected by X-ray,the width of the knee joint was measured,oxidative stress indexes and inflammatory factors levels in serum and joint lavage fluid were detected,the morphology of the knee joint was observed by hematoxylin-eosin staining,full-thickness cartilage and hyaline cartilage thickness were measured,and the content of articular cartilage proteoglycan was observed by safranin O-fast green staining.The"drug-component-disease-target"network was constructed.Gene ontology enrichment analysis and Kyoto encyclopedia of genes and genomes enrichment analysis of effective targets were performed,and protein-protein interaction network maps were constructed using cytoscape software. RESULTS AND CONCLUSION:Sambucus adnata Wall extract could reduce tumor necrosis factor-α level in joint lavage fluid and serum levels of prostaglandin E2 and malondialdehyde,while increase the level of superoxide dismutase;relieve joint swelling caused by osteoarthritis;improve the histopathological state of articular cartilage,maintain the thickness of full-thickness articular cartilage,hyaline cartilage and the area of bone trabeculae in subchondral bone;and effectively prevent the loss of proteoglycans in articular cartilage and have a chondroprotective effect.Network pharmacological results showed that the methanol extract of Sambucus adnata Wall may have some targets related to inhibition of tumor necrosis factor,AKT1,interleukin-6,MAPK3,and SRC as well as inhibition of over-activation of EGFR signaling pathway and AGE-RAGE signaling pathway.

BACKGROUND:Previous studies showed that extracts of Sambucus adnata Wall.have the ability to promote the proliferation and differentiation of osteoblasts,fracture healing,anti-inflammatory and antioxidant effects,which can effectively alleviate the development of osteoarthritis.Vascular endothelial growth factor,on the other hand,is a biomarker for the evaluation of osteoarthritis severity. OBJECTIVE:To investigate the effect and mechanism of two extracts of Sambucus adnata Wall.(methanol extract SAW-ME and dichloromethane extract SAW-DCE)on angiogenesis in osteoarthritis. METHODS:(1)Rat models of osteoarthritis were established using anterior cruciate ligament transection and given SAW-ME and SAW-DCE.A sham group was set as a control.Immunohistochemistry and immunofluorescence were used to detect the changes of articular vascular endothelial growth factor A in joint tissue and vascular endothelial growth factor and"H"type blood vessels in serum of osteoarthritis rats.(2)Vascular endothelial cells EA.hy926 were used as the research object and intervened with SAW-ME and SAW-DCE.Cell proliferation was then detected by MTT assay.Vascular endothelial growth factor was used to induce EA.hy926 cells,and the model of angiogenesis was replicated.Cell scratch assay and tube formation assay were performed to study the role and mechanism.(3)EA.hy926 cells were used for transcriptome sequencing to analyze the characteristic changes of cell differential genes and related functions after SAW-DCE intervention. RESULTS AND CONCLUSION:(1)SAW-ME and SAW-DCE downregulated the expression of vascular endothelial growth factor A in the rat knee cartilage and reduced the formation of"H"type vessels in osteoarthritis rats.SAW-ME could significantly decrease the level of vascular endothelial growth factor in serum of osteoarthritis rats(P<0.05).SAW-DCE could also decrease the level of vascular endothelial growth factor in serum of osteoarthritis rats,but there was no significant change.(2)Both SAW-ME and SAW-DCE significantly inhibited vascular endothelial cell migration and tube formation,and downregulated the expression of Ang1 and Tie2 proteins.(3)Transcriptome sequencing analysis found that abnormal angiogenesis in osteoarthritis was related to the PI3K/AKT signaling pathway.(4)To conclude,SAW-ME and SAW-DCE can inhibit angiogenesis in the rat model of osteoarthritis,and the mechanism may be related to the Ang1/Tie2 and PI3K/AKT signaling pathways.

Objective To systematically review whether mirror therapy(MT)intervention can effectively improve upper extremity motor function and activities of daily living(ADL)in stroke patients;whether its improvement is affected by pa-tients'age and disease course;and whether MT's influencing factors,such as intervention period,time,and fre-quency,have a dosage effect on upper extremity motor function and ADL. Methods Seven databases were searched,including Embase,Web of Science,PubMed,Cochrane Library,Wanfang data,VIP and CNKI from establishment to April,2023,and randomized controlled trials of MT for upper extremity motor function and ADL in stroke patients were screened.Quality assessment was performed using Physiothera-py Evidence Database(PEDro).Meta-analysis was performed using RevMan 5.4.1,and network meta-analysis was performed using R software,reticulated meta-analysis tables and cumulative probability tables were drawn for ranked comparisons,and funnel plots were drawn to test for publication bias of the outcome indicators using Stata 17.0 software.GRADE was used to evaluate the quality of evidence for the outcome indicators. Results A total of 13 papers(532 patients)were included.The PEDro score ranged from 6 to 8.Most of the literature did not report the blinding completely or did not implement allocation concealment,which might have some limita-tions.MT could improve the scores of Fugl-Meyer Assessment-Upper Extremities(n = 466,MD = 6.05,95%CI 3.44~8.66,P<0.001),Barthel index(n = 230,MD = 9.95,95%CI 6.23~13.68,P<0.001)and Functional Inde-pendence Measure(n = 147,MD = 4.17,95%CI 2.61~5.72,P<0.001)in stroke patients.Network meta-analysis showed that MT was more effective in upper limb motor function intervention for stroke patients aged 40 to 59 years with a disease course less than three months;and an intervention period less than four weeks,single inter-vention time less than 30 minutes,intervention duration daily more than 30 minutes and intervention twice daily might optimize the effects on upper limb motor function. Conclusion MT is effective on upper limb motor function and ADL in stroke patients,and the effect on upper limb mo-tor function is affected by the age and disease course of the patients,as well as the period,time and frequency of intervention.
