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.

BACKGROUND:Our previous study has already manifested that Chinese medicine Xiaokening can effectively prevent and treat the early diabetic nephropathy. OBJECTIVE:To compare the effect of rhein and archen on the apoptosis of mesangial cells of rats cultured with high glucose. METHODS:Mesangial cells were stimulated by different concentrations of rhein and archen (20, 40 and 80 μmol/L). Morphology of apoptotic cells was observed by hematoxylin-eosin staining. Karyon apoptosis was examined by fluorescence staining of DAPI. cellapoptosis rate was detected by flow cytometry. RESULTS AND CONCLUSION:The outcome of hematoxylin-eosin staining and DAPI staining indicated that the effect of rhein was much stronger than that of archen on the apoptosis of mesangial cells in the rats cultured with high glucose. Comparison of the apoptosis rate also indicated that the rhein had a stronger effect on the earlier and the later stage apoptotic rate of mesangial cells than archen. Both rhein and archen with different concentrations can induce apoptosis of mesangial cells, but the effect of rhein is much stronger.

Objective To evaluate the relationship between femoral artery intima-media thickness (FA-IMT), stiffness, hemodynamics factors of femoral artery and peripheral vascular disease (PVD) in type 2 diabetes mellitus. Methods According to the presence of PVD, 151 patients with type 2 diabetes were divided into PVD group and non-PVD group. FA-IMT was tested with 2D ultrasound. Ds, Dd, PSV, EDV were observed with color flow rate and volume quantitative technology. FA-IMT, FA-stiffness β, peak systolic velocity (PSV) and end diastolic velocity (EDV) were compared between the two groups. Results Compared with non-PVD group, FA-IMT and FA-stiffness β increased in PVD group (P＜0.01), whereas PSV and EDV decreased in PVD group (P＜0.01). There was no relationship between FA-stiffness β and FA-IMT in PVD group (P=0.01). Multiple Logistic regression indicated the presence of PVD symptoms associated closely with FA-stiffness β, PSV, EDV and duration of diabetes. Conclusion Stiffness β plays an important role in the clinical evaluation of type 2 diabetes mellitus.
