Detection of Oncotype DX and MammaPrint has been recommended by the American Society of Clinical 0ncology.For specific populations,such as early endocrine-dependent breast cancer,under the condition of sufficient evidence in the evidence-based medicine,we can choose genetic testing in combination with clinical pathologic factors to guide clinical treatment,which has reached the goal of micro combined with macro,more detailed division of the patients,and individualized treatment.

Abstract
The possible mechanisms of developmental dyslexia mainly include the hypothesis of language framework and the hypothesis of non-verbal framework. The language framework assumes that people with developmental dyslexia may exhibit defects in phonetic awareness, rapid naming, phonetic memory, and orthographic processing. Studies of developmental dyslexia in Chinese have found that deficiencies in orthography may be an important cause of dyslexia, but there are diverse views and opinions regarding orthography processing. This article sorts out the research progress in behavioral and neuroimaging aspects of orthography studies, and provides references for further development of processing test materials and methods in the research of processing mechanism of developmental dyslexia orthography.

Objective:
To characterize visual attention span in children with developmental dyslexia in Xinjiang and to explore the effects of action video game training on visual attention span,and to provide a reference for improving the visual attention span of children with dyslexia.
Methods:
Students from grade 3 to 5 in primary schools of Xinjiang were selected by using random clustering sampling method from July to November 2020,a total of 120 developmental dyslexia group (Group-DD), chronological age matched group (Group-CA) and reading level matched group (Group-RL) were selected and compared with visual attention spans, action video games were used to conduct intervention training for DD children, variance analysis was used to study the variation of visual attention span.
Results:
The accuracy and discrimination index of Group-DD (0.68±0.10, 1.21±0.87) were lower than those of Group-CA (0.77±0.99, 1.80±0.83) and Group-RL (0.71±0.11, 1.50±0.75) ( F =21.26, 15.19, P <0.05);there was no significant difference in reaction time among the three groups( P >0.05). There were statistically significant differences in the accuracy of visual attention span (0.63±0.12, 0.71±0.11,0.70±0.10), response time (760.51±185.83, 782.74±149.20, 857.27± 155.44 ), and discrimination (0.84±0.81, 1.51±0.19, 1.29±0.10) among children of different grades ( F =6.37,3.81,3.16, P < 0.05 ). After 12 hours of action video game training, the accuracy and discrimination of Group-DD intervention group (0.74±0.10, 1.53±0.88) were higher than those of Group DD control group (0.68±0.14, 1.06±0.97)( P <0.05), and there was no significant difference between Group DD intervention group and Group RL (0.76±0.12, 1.73±0.71) ( P >0.05), but there was statistical difference between Group DD intervention group and Group-CA (0.81±0.94, 2.17±0.79) ( P <0.05).
Conclusion
Children with dyslexia have deficits in visual attention span, with grade difference. Action video game intervention can improve visual attention span ability of developmental dyslexia children to some extent.

OBJECTIVES:
The results of elastic imaging in evaluating the function and histopathological changes of allogeneic renal transplantation are contradictory, one of the important reasons may be that there are differences in human parameters related to kidney transplantation among individuals. The purpose of this study is to explore the related human body parameters on shear-wave elastography (SWE) effects on quantitative stiffness of graft cortex.
METHODS:
From March 2021 to November 2021, a total of 63 patients with allogeneic kidney transplantation in the Department of Ultrasonography, Third Xiangya Hospital, Central South University, were selected to collect the parameters of two-dimensional, color Doppler and SWE. The subjects were divided into a <20% group and a 20%-30% group according to the variation of cortical hardness measurement. Mann Whitney U test was used to compare the differences in relevant human parameters, and Spearman rank correlation was used to analyze the correlation between relevant human parameters and cortical hardness of transplanted kidney.
RESULTS:
There was no significant difference between the 2 groups in age, sex, postoperative time, resistance index of interlobar artery, SCr, blood uric acid, ratio of fat layer to muscle layer, and BMI (all P>0.05). Compared with the <20% group, the patients in the 20%-30% group had smaller cortical hardness of the transplanted kidney, greater total distance between the transplanted kidney and the skin surface, and thicker fat layer or muscle layer in front of the transplanted kidney (all P<0.05). The age of patients, the total distance from the transplanted kidney to the skin surface, the thickness of fat layer and muscle layer, the ratio of fat layer to muscle layer, BMI, and the variation of cortical hardness were significantly negatively correlated with the cortical hardness of the transplanted kidney (all P<0.05).
CONCLUSIONS
Human parameters relevant to kidney transplantation affect the accuracy of SWE in measuring the cortical hardness of the transplanted kidney. It is very important to obtain the highly stabile elastic measurement value and interpret the elastic measurement results according to different levels of human body related parameters in combination with individual conditions.
