Chinese Journal of Applied Physiology 2014;30(2):142-146
OBJECTIVETo observe the effect of the postpone in skeletal muscle aging process of D-galactose rats by weight training and soy polypeptide supplement in 6 weeks, and discuss the initial mechanism.
METHODSixty male SD rats (three month old)were randomly assigned: 6 week control (C6,) and 6 week model (M6) 6 for each group, 12 week model (M12), big load (B12), small load (S12), peptide (P12), peptide + big load (PB12) and peptide + small load group (PS12) 8 for each group, eight fourteen month rats were taken in the natural aging group. The rats were killed by the end of 6th week and 12th week, tested the indicators.
RESULTCompare with group C6, the indicators in group M6 showed aging in different levels; Compare with group M12, weight training or soy polypeptide supplement in all intervention groups could increase the content of skeletal muscle superoxide dismutase (SOD), SOD/MDA, the serum growth hormone(GH), insulin-like growth factor-1 (IGF-I)and skeletal muscle IGF-I mRNA, decreased the malondialdehyde (MDA) content of skeletal muscle, and they had notable interaction.
CONCLUSIONRat skeletal muscle aging model can be copied successfully by D-galactose hypodermic, and go on with 6-week weight training or soy polypeptide supplement, they can postpone the skeletal muscle aging process of D-galactose rats, and the two interference way united can have more obvious effect. Its preliminary mechanism may be related to the reduction of skeletal muscle oxidative stress and lipid peroxidation, the correction of hormones and related factors metabolic disorders, the elevation of skeletal muscle IGF-I mRNA expression and so on.

6.Search in sports and learning situation of children in Nantong with short stature causing by different etiologies
Acta Universitatis Medicinalis Anhui 2015;(8):1146-1149
Objective To investigate the common etiologies,sports and learning situation of children in Nantong with short stature,and discuss the relationship between the two. Methods Did a retrospective analysis of 108 cases of children with short stature in Nantong University′s affiliated hospital since January 2012. Through detailed past illnesses, physical examination, laboratory tests, diagnose short stature and clarify the cause. Did a questionnaire to these children with short stature about sports and learning situation. Use statistical methods like multivariate Logis-tic regression analysis and link analysis to analyze sports and learning situation of children in Nantong with short sta-ture and find the relation with the etiology. According to the principle of group matching,the control group elected representative of 108 children. Results In 108 cases, 61 cases were because of growth hormone deficiency (GHD), accounting for 56. 5% ; 47 cases were because of non-growth hormone deficiency (NGHD), accounting for 43. 5% . Logistic regression analysis showed that participation in physical exercise was a protective factor. Rest-less anxiety and inattention were as risk factors,and these make a lot(P < 0. 001, OR = 7. 483, 95% CI = 2. 620 ~21. 374). There was no significant relation between common cause and sports, learning situation ( P > 0. 05). Conclusion Various types of sports (basketball, badminton, running, cycling) are protective factors for children of short stature. Restless anxiety and inattention are risk factors for children with short stature. Whether there is growth hormone deficiency or not, children with short stature should increase the right exercise as much as possible and avoid or reduce exposure to these risk factors.

Objective To compare the outcomes between radiofrequency modification and augmentation reconstruction in the treatment for partial anterior cruciate ligament( ACL) tears. Methods Fifty?four patients with partial ACL tears were divided into radiofrequency modification group( n=16) and augmentation reconstruc?tion group( n=38) according to different treatment methods. Minimum follow?up was 2 years. Patients were eval?uated just after the injury and at the latest follow?up with several parameters, including the international knee documentation committee( IKDC) score,Lysholm knee score,Tegner activity rating,range of motion ( ROM) and the kneelax arthrometer. Results The kneelax was (4. 4±0. 9) mm of preoperative, (5. 0±1. 5) mm of post?operative in radiofrequency modification group,the difference was no signifiacnt( t=1. 372,P=0. 183);in aug?mentation reconstruction group was (4. 7±0. 8) mm and (1. 7±1. 0) mm respectively,the knee stability was in?crease significantly postoperative;knee stability was significantly improved in the augmentation reconstruction group compared with the radiofrequency modification group( t=9. 228,P=0. 000) . In radiofrequency modifica?tion group,ROM,Lysholm score and Tegner score were improved significantly between the results pre?and post?operatively((105. 4±22. 5)° vs. (123. 5±11. 4)°,t=59. 189,P=0. 000;65(51,90)) points vs. 86(59,100) points,Z=3. 852,P=0. 000;3(1,5) points vs. 6(1,9) points,Z=4. 637,P=0. 000). In augmentation recon? struction group, ROM,Lysholm score and Tegner score were improved significantly between the results pre?and post?operatively((99. 4±21. 9)° vs. (125. 3±10. 9)°,t=6. 527,P=0. 000;(65(51,89) points vs. (85 (59, 100) points,Z=4. 427,P=0. 000;3(1,5) points vs. 6(1,9) points,Z=3. 961,P=0. 000). Conclusion Augmentation reconstruction technique is more beneficial to the knee stability than radiofrequency modification in the treatment for the partial ACL tears.
