ABSTRACT
Objective@#To analyze the relationship among cardiopulmonary endurance, body composition, flexibility, muscle strength and endurance with functional movement performance of male college students, and to explore the factors associated with the performance of functional movements.@*Methods@#A total of 112 male college students were selected, muscle power and flexibility test was based on the national student physical health standard, founctional movement screen created by Cook was used to test founctional movement performance.@*Results@#Male college students have poor flexibility, stability and control of functional movements, and high probability of compensatory or asymmetric movements; In-line lunge, trunk stability push-up were positively associated with cardiorespiratory fitness(r=0.17, 0.17, P<0.05); hurdle step, shoulder mobility, trunk stability push-up and rotary were negative associated with body composition(r=-0.17, -0.13, -0.25, -0.22,P<0.05); shoulder mobility, trunk stability push-up and rotary were positively associated with score of standing long jump, trunk stability push-up was positively associated with endurance of deltoid and trapetus as well as endurance of pectoralis major and latissimus dorsi; shoulder mobility was positively associated with score of sit and reach(r=0.17, P<0.01). The independent risk factors of functional performance of male college students, hurdle step(β=-0.02), trunk stability push-up (β=-0.12) and rotary were body fat rate(β=-0.03); the protective factors trunk stability push-up were body fat rate(β=-0.04), VO 2max (β=0.04) and endurance of pectoralis major and latissimus dorsi(β=0.03).@*Conclusion@#The functional performance of male college students was not optimistic, which could be improved by increasing health-related physical fitness.
ABSTRACT
AIM To study the chemical constituents from the roots tuber of Aconitum ouvrardianum H..METHODS The ethyl acetate fraction of methy extract from A.ouvrardianum roots tuber was isolated and purified by silica,aluminium oxide column,Sephadex LH-20,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Eighteen compounds were isolated and identified as kongboendine (1),anisoezochasmaconitine (2),lipo-14-O-anisoylbikhaconine (3),franchetine (4),talatisamine (5),chasmanine (6),crassicauline A (7),chasmaconitine (8),14-dehydrotalatisamine (9),lipoindaconitine (10),indaconitine (11),yunaconitine (12),lipoyunaconitine (13),liljestrandisine (14),transconitine B (15),ouvrardiantine (16),atropurpursine (17),8-deacetylyunaconitine (18).CONCLUSION Compounds 1-4,9-10,13,15,17 are isolated from this plant for the first time.
ABSTRACT
Objective To explore the relationship between drinking water from farmland edge and digestive tract cancers in rural areas.Methods A total of 180 cases of digestive tract cancers from Longquan city,Jinyun county and Qingtian county were selected and 360 controls with the same age group and sex were enrolled.1∶2 matched design of case-control study was used.The data was analyzed by Wilcoxon matched -pairs signed -ranks test.Results Overall,individuals who drank water from farmland edge were more likely to have digestive tract cancer among 3 areas (OR=4.005 ,95%CI:2.228-7.199).In Qingtian county the risk of digestive tract cancers in individuals who drank water from farmland edge was 5.375 times of control group population (95%CI:2.287 -12.635 ),But there was not statistically significant in Longquan city and Jinyun county (P >0.05 ).For gastric cancer,the proportion of drinking farmland edge water was significantly higher in cases than that in control group (OR=4.875,95%CI:2.007-11.839),while the difference was not statistically significant for liver cancer,colorectal cancer and esophageal cancer (P>0.05 ).In Qingtian county ,for gastric cancer,the proportion of drinking water from farmland edge was 5.750 times of control group population (95%CI:1.683-19.649).But there was not statistically significant in other cancers(P>0.05).Conclusion Drinking water near farmland edge may be one of the risk factors of gastric cancer in rural areas.
