AIM:To analyze the recovery of visual cortex activation range of color vision in anisometropia amblyopia children after treatment by using blood oxygen level dependence-functional magnetic resonance imaging ( BOLD- fMRI ) and SPM8 software.
METHODS:Self-control study. This fMRI study directly compared activity in visual cortex produced by color monocular stimulation in 13 monocular anisometropia amblyopia children. The project of study was blocked design. The data of functions and anatomical MRI was stimulated by three-primary colors and was preprocessed and analyzed by SPM8 that based on MATLAB software. According to the data, we compared the change of the central area of color vision when first visit and 1, 2 ,4wk after treatment.
RESULTS: The BA17, BA18, BA19 and BA37 of amblyopia children were different activated after they accepted the three-primary colors stimulation (P<0. 01). After 4wk treatment, amblyopia children accepted red stimulation, the visual cortex activation range without expanding; after accepting green stimulus, on the left side of the visual cortex BA37, BA19, BA20, the average t value were 3. 5210, 3. 2716, 3. 1534 ( P< 0. 01 ); after accepting blue stimulation, the scope of the right side of visual cortex at BA19, BA18 were expanded to different extent, the average t value were 3. 7345, 3. 2701 (P<0. 01).
CONCLUSION: After 4wk treatment, visual cortex activation of color vision of anisometropia amblyopic children is expanded, but with low extent, after the short-term treatment of amblyopia, visual cortex activation of color vision has a certain degree of recovery but not obvious.

Objective To investigate the correlation between the expressions of tumour suppressor gene PTEN and oncogene C-myc in colorectal carcinoma.Methods The expressions of PTEN and C-myc protein in normal colorectal mucosa(n=8), adjacent non-cancerous tissues(n=10) and primary colorectal carcinoma tissues(n=60) were observed by S-P immunohistochemical assay.Results Of 60 colorectal carcinoma tissues,C-myc protein was detected in 46 cases.The expression rate of C-myc in the primary colorectal carcinoma tissues(76.70%) was significantly higher than that in the normal(0) and adjacent non-cancerous tissues(10%)(P0.05).The positive expression rate of PTEN protein in the primary colorectal carcinoma tissues(25.00%,15/60) was significantly lower than that in the normal(100%) and adjacent non-cancerous tissues(90%)(P
