BACKGROUND:Core training has been gradual y accepted worldwide.“Core”is only a generalized perception, and how to define the muscles, the difference among the muscles and the mode of the muscle recruitment consist of the important part of research work on core training.
OBJECTIVE:From the aspects of theoretical basis, the development of training methods and measurement of training effectiveness, to elaborate the method issues and new insights on core stability training.
METHODS:PubMed, ScienceDirect and CNKI databases were searched by the keywords of“core training, core exercise, core strength”in the titles and abstract to retrieve relevant articles published from 1979 to 2013.
RESULTS AND CONCLUSION:The neural subsystem was first reported by Panjabi to monitor the various signals from the transducers and direct the active subsystem to provide the needed stability. Neutral zone is regarded as an important clinical indicator relevant to spinal stability. Spinal injury and muscle weakening can result in spinal instability and even low back pain and peripheral pain. Core trainings include Swiss bal , plank exercise, sling exercise and so on. Up to now, research on core training is focusing on its mechanism. Core stability training is not only defined as torso stability training, but also refined to the stability training of each joint.

Objective To compare the field-matching techniques and dosimetric characteristics in the target area of testicular seminoma including the abdominal and pelvic cavities between direct aperture optimization intensity modulated radiation therapy (DAO-IMRT) and 3D conformal radiation therapy (3D-CRT),and to analyse the advantages and disadvantages of DAO-IMRT.Methods DAO-IMRT and 3D-CRT plans were designed with Pinnacle treatment planning system for 7 testicular seminoma patients,and the characteristics of both the irradiation methods were analyzed and evaluated by means of the parameters like dose homogeneity indexes,dose volume histograms and etc.Results DAO-IMRT had the hot and cold volumes in the target areas both significantly smaller than those by 3D-CRT,while the conformity index and homogeneity index superior to those by 3D-CRT.The mean doses (Dmean) by DAO-IMRT of the organs at risk (OAR) except the left femur head were all lower than those by 3D-CRT,aud the V15 values of liver,double kidney,small intestine and rectum by DAO-IMRT were statistically lower than those by 3D-CRT (P＜0.01).3D-CRT had the V5 values of OAR all lower than those by DAO-IMRT,in which the differences of double kidney,small intestine,bladder,left femur head and normal tissues were significant statistically (P＜0.05).The monitor units by DAO-IMRT roughly doubled when compared with those by 3D-CRT,and the difference was also significant (P＜0.01).Conclusion DAO-IMRT with easy operation and high reliability can avoid the connection of fields in the target area of testicular seminoma,and is superior to 3D-CRT in dosimetry.

The cyclic voltammetric behaviors of sodium selenite on the gold electrode modified by L-cysteine self-assembled monolayer (L-Syc,Au/SAMs) has been investigated in 0.05 mol/L H_2SO_4 solutions with sodium selenite. Sensitive anodic stripping current of selenium (Se) with the peak potential at 0.99 V (vs. SCE) has been observed. In comparison with the electrochemical properties of sodium selenite on the modified electrode with those on the naked gold electrode, it was found that selenite was reduced to selenium by the redox interaction with sulfur on the monolayer and the monolayer catalytically oxidizes Se as the electrode was positively scanned. According to the electrochemical properties of sodium selenite both on the naked and modified gold electrode, the Se deposition mechanism and catalytic mechanism as well as bionic membrane model were proposed for the bio-utilization of selenite through nano scale selenium.

Objective To investigate the single nucleotide polymorphisms ( SNP) of IL-13G+2044A and IL-13A-1512C and to analyze their relationships with the occurrence of bronchial asthma in chil-dren in Guiyang city. Methods Sequenom MassArray platform, a newly developed genotyping assay, was used to detect the G+2044A locus and the A-1512C locus in 153 subjects with asthma and 103 healthy sub-jects. Then the results were statistically analyzed with chi-square test and t-test. Results Three genotypes of IL-13G+2044A locus including GG, GA and AA were detected in the subjects with or without asthma. There were significant differences in the genotype distribution between the subjects with or without asthma (χ2 =7. 691, P<0. 05). The subjects carrying the variant allele A at IL-13G+2044A locus were more likely to have asthma than those not harboring the variant allele A. There were significant differences in allele fre-quency between the subjects with or without asthma (χ2 = 7. 458, P<0. 01). Three genotypes of IL-13A-1512C locus including AA, AC and CC were detected in the subjects from both of the two groups. There were significant differences in the genotype distribution between the two groups (χ2 = 12. 906, P<0. 01). The variant allele C at IL-13A-1512C locus was associated with lower risk for asthma. Significant differences in allele frequency were observed the two groups (χ2 =10. 407, P<0. 01). Conclusion Both of the alleles at IL-13G+2044A and IL-13A-1512C loci were associated with asthma. The variant allele A at IL-13G+2044A locus might be the gene predisposing children to asthma in Guiyang city. Children carrying the variant allele C at IL-13A-1512C locus showed a lower risk for asthma in Guiyang city.
