A ZnO nanofibers carrier on the Pt electrode via electrospinning technology was prepared and then the Keggin phosphotungstic acid was deposited on the ZnO/Pt electrode using electrodeposition technology. The scanning electron microscopy showed that the zinc oxide fibers presented net structure and the diameter of its fiber was about 300 nanometers. The fourier transform infrared spectroscopy confirmed that the phosphotungstic acid adhered to the fiber surface. The electrochemical property of the modified electrode showed that it exhibited rapid response, excellent sensitivity and good stability, achieving rapid and accurate determination. The electrode responded linearly to ascorbic acid ( AA) in a concentration range from 8. 8 × 10-7 to 3. 3 × 10-4 mol/L with a low detection limit of 2. 5 × 10-7 mol/L. The method is promising for the development of AA detecting instrument.

Objective To investigate the correlation between shear wave velocity and tissue fibrosis score in thyroid space-occupying lesions.Methods The shear wave velocity of 55 thyroid space-occupying lesions was examined by virtual touch tissue quantification.The shear wave velocity of different solid parts of the lesions was detected for several times and 15 data were genarated.Then maximum and minimum value were removed.The maximum (Vmax),minimum (Vmin),mean (Vm) of shear wave velocity were calculated with the rest of 13 data.Meantime the fibrosis degree of these pathological lesions were scored by using optical micorscope.The maximum (Fmax),minimum (Fmin) and mean (Fm) fibrosis degree were calculated with these scores.Then the difference between Fmax,Fmin and Fm value of benign lesions and malignant lesions was analyzed.The linear correlation between Fmax and Vmax,Fmin and Vmin,Fm and Vm was also analysed.Results In the 55 lesions,30 lesions were benign and the rest was malignant.The Fmax,Fmin,Fm of benign lesions were 1.38 ± 1.44,0.68 ± 0.25,0.91 ± 0.73 respectively; the corresponding value of malignant lesions were 5.00 ± 1.91,3.52 ± 1.82,4.08 ± 1.75 respectively.There was significant difference between the benign group and malignant group (t test,P ＜0.01).There were linear correlation between Fmax and Vmax,Fmin and Vmin,Fm and Vm and the Pearson correlation coefficients were 0.504,0.284,0.453 respectively.Conclusions The shear wave velocity and fibrosis degree of thyroid lesions has linear relationship.The heavier the degree of fibrosis is,the faster the shear wave velocity would be.

Objective To investigate the impact of aging and weight bearing on cartilage endplate morphology and chondrocyte apoptosis in rats. Methods The bipedal rat model (n=45) was developed by forelimb amputation and special breeding methods. The normal rats of the same age served as the control group (n=40). When the rats became 3, 6, 9, and 12 months old, 8 rats randomly selected from each group were sacrificed and paraffin-embedded mid-sagittal sections of the L4-5 spine were obtained. Sections were stained with hematoxylin and eosin and the TUNEL procedure was performed. The numbers of apoptotic cells and viable cells in the cartilage endplates of the intervertebral discs were counted, the thickness of the cartilage endplate was measured and the degree of impairment of the cartilage endplate was evaluated. Results Apoptosis first appeared in the cartilage endplate, then increased with aging and resulted in a remarkable decrease in cell density. The apoptotic rate of chondrocytes within the cartilage endplate of the bipedal rat model group was significantly higher than the control group at the 6-month time point. A statistically significant difference was observed in the bipedal rat model group between the 6-month time point and 9-month time point (P<0.05). Correlation analyses indicated that there was a highly negative correlation between the number of the viable cells of the cartilage endplate and the degree of the cartilage endplate degeneration (r=-0.97, P<0.05). Compared with the naturally aged group, the bipedal rat model group experienced more severe degeneration in the structure of the cartilage endplate, more obvious thickening of the cartilage endplate's calcified layer, and more defects in the structure of the cartilage. Conclusions Besides aging, weight bearing is probably a key factor of the increase of chondrocyte apoptosis and the degeneration of vertebral cartilage endplate.
