Objective The purpose of this study was to assess isokinetic strength of lower extremities and find out weak muscles in Chinese elite fencers. Methods Bilateral peak torque of flexors and extensors of hip, knee and ankle in 26 national fencers,aged 23.1±2.36 yrs,were tested isokinetically at speeds of 60 and 240 deg/sec. Results (1)Hip: compared with 60 deg/sec,peak torques of bilateral extensors significantly decreased at 240 deg/sec (P<0.05), no significant difference in flexors(P>0.05); At two velocities, flexor peak torques in leading leg of men fencers were significantly higher than trailing one(P<0.05),no significant difference was found in women(P>0.05);Flexor/extensor torque ratio was lower than normal at two velocities in all fencers. (2)Knee: strength of flexors and extensors in 60 deg/ sec and extensor in 240 deg/sec of men fencers were significantly different between leading and trailing legs (P<0.05); No difference at two velocities were found in women fencers;knee flexor/extensor ratio of both legs were 0.56,0.54 for women and 0.6,0.67 for men respectively at 60 deg/sec;knee flexor/extensor ratio were within normal range at 240 deg/sec. (3)Ankle:men's peak torque in leading ankle of flexor and extensor were significantly higher than trailing leg at 60 deg/sec(P<0.05);no difference were found at 240 deg/sec for men and women (P>0.05); ankle flexor/extensor ratio were lower than normal at two velocities in all fencers. Conclusion (1)Bilateral asymmetry in isokinetic muscle strength exists in men fencers,but not obvious in women fencers. (2)Weak muscles for fencers were hip extensor,knee flexor,especially in leading knee and ankle extensor.

BACKGROUND: Defected Laryngeal cartilage has many alternatives, including autologous cartilage, al ograft cartilage and metal stents. Although these materials can achieve desired outcomes in laryngeal cartilage defect repair, certain limitations exist. OBJECTIVE: To investigate the biocompatibility and properties of artificial ossicular chain reconstruction materials, and to explore the effect of artificial ossicular chain reconstruction materials on laryngeal cartilage defect repair. METHODS: Porous hydroxyapatite otosteon was prepared by high-temperature calcination of hydroxyapatite, fol owed by cultured in bone morphogenetic protein solution extracted from fresh human bone to construct bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material. And then, the biocompatibility and characteristics of the material were analyzed. Forty adult male New Zealand white rabbits were randomly divided into porous hydroxyapatite group and artificial ossicular chain reconstruction material group (n=20 per group), and underwent repair with porous hydroxyapatite material and bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material respectively after modeling of laryngeal cartilage defect. RESULTS AND CONCLUSION: There was a significant difference in compressive strength of artificial ossicular chain reconstruction materials with different porosities. No symmetry sphere formed in hol ows of the outer surface of the material, with polygonal appearance and with a pore size of 100-200 μm. There were no obvious adverse reactions in both two groups after implantation, but in the artificial ossicular chain reconstruction material group, numerous fibrous connective tissues and obvious bone nodules appeared, and the degradation rate of the material was faster. These results suggest that the bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material exhibits good biocompatibility and properties, which wil obtain satisfactory outcomes for laryngeal cartilage defect repair. So, the material holds a great value of clinical application.

Objective To explore the effect of individualized nutritional nurses involved in intervention on quality of life for cancer patients. Methods The articles were searched by Chinese full- text periodical database, Wanfang database, VIP database, PubMed, Cochran Library from 1995 to July 1 2015, and the articles and data were extracted by two researchers using Cochrane systematic review methods using RevMan5. 3 Meta- analysis software. Results The final results included five randomized controlled study, 358 cases of patients. Individualized nutritional quality of life of patients in the intervention group compared with the usual care group, within three months 27.76 points high quality of life, MD = 27.76,95% CI was 8.83-46.68; three months of life high quality 31.64 points, MD = 31.64, 95% CI was 9.70-53.59,6 months or more (including 6- month) high quality of life 34.26 points, MD = 34.26, 95% CI was 3.69-64.84, were statistically significant (P<0.05). Conclusions Nurse participation can improve the quality of life of patients and long-term effects also have some role in promoting. Due to the limitations of this study we need more high quality randomized controlled studies and Meta analysis to verify.

Objective To explore the effect of hypoxia-ischemia(HI)on expression of second mitochondria-derived activator of caspase proteinc(Smac)in brain tissue of neonatal rats.Methods All neonatal rats were divided randomly into HI group,pseudo-operation group,and normal control group.The animal models of HIE were made.At 24,48,72,96 h after HI,Western blot was used to detect the expression of Smac protein in hippocampus.The relative activity of Caspase-3 in hippocampus tissue was determined by colorimetric assay.Results In HI group,at 24,48,72,96 h after HI,the expression levels of Smac protein in hippocampus significantly increased compared with that of pseudo-operation group and normal control group(Pa

Objective To investigate the diffusion-weighted imaging (DWI)characteristics and the correlation of diffusion coeffi-cient (ADC)and differentiation grade of rectal tubular adenocarcinoma.Methods The DWI characteristics of thirty-eight patients pathologically comfirmed rectal tubular adenocarcinomas were evaluated respectively.There were 9 highly differentiated tubular ade-nocarcinomas,1 5 moderately differentiated tubular adenocarcinomas and 14 poorly differentiated tubular adenocarcinomas.The ADC value was calculated from two different factors (0 and 1 000 s/mm2 ).The correlation between ADC value and the differentiated de-gree of tumour was statistically analysed.Results The mean ADC for highly differentiated group was (0.92±0.05)×10 -3 mm2/s, and the mean ADC for moderately differentiated group was (0.79 ± 0.10)× 10 -3 mm2/s whereas that for poorly differentiated group was (0.71±0.06)×10 -3 mm2/s.The difference among three groups was statistically significant(P <0.05).The ADC value and the differentiated degree of tumour were negatively correlated(Spearman r =-0.704)P<0.01.Conclusion DWI and ADC value can be a useful estimating for the differentiation of rectal tubular adenocarcinoma.

Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics, photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity, there were significant differences of morphological characteristics, photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and P(n). Twelve populations were divided into three-type. The three populations of Xuyi, Mingguang and Fengyang were of narrower-longer leaf, bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.
