2.Effect of BNIP3-induced autophagy in gastric carcinoma
Chinese Pharmacological Bulletin 2014;(12):1730-1733
Aim To study the effect of BNIP3 on hy-poxia-induced autophagic cell death in gastric carcino-ma.Methods The protein levels of BNIP3 and LC3-Ⅱ of 1 8 cases of gastric carcinoma were studied with immunocytochemistry and Western blot analysis be-tween normal and tumor tissues.The expression of LC3-Ⅱ in SGC-7901 cells was assessed while knock-down of BNIP3 by siRNA in CoCl2-induced hypoxia, and the effect of 3-MA was also studied.Cell viability in hypoxia treatment for 48 h was estimated with cell counting kit-8 (CCK8).Results Compared with nor-mal tissues,the protein levels of BNIP3 and LC3-Ⅱwere increased in tumor tissues.BNIP3 siRNA could decrease the expression of LC3-Ⅱ and enhance the cell viability,while inhibition of autophagy could also in-crease the cell viability in SGC-7901 cells.Conclu-sions BNIP3 may play a role in hypoxia-induced cell death in gastric carcinoma,and the possible mecha-nism may be related to the regulation of autophagy.

9.Precise mechanical analysis on the femoral three-dimensional finite element model constructed based on DICOM data
Chinese Journal of Tissue Engineering Research 2013;(30):5483-5489
BACKGROUND:The finite element model has been developed from two-dimensional model to three-dimensional model, from linear model to nonlinear model. As the advantage of this method in the analysis of mechanical characteristics of the irregular objects, the finite element model has been widely used in the research of orthopedic biomechanics, especial y in the research of hip joint. OBJECTIVE:To analyze the stress state of human femur with finite element analysis method and to investigate a method that can rapidly construct femoral finite element model and precisely analyze the biomechanics. METHODS:Normal male femur was used as specimen for CT scan to obtain cross-sectional images of femur in each slice. Three-dimensional reconstruction was performed with DICOM data and MIMICS software, then the femoral three-dimensional finite element model was established with the finite element analysis ABQUS 6.8 software, and the stress distribution of the model was analyzed under loading condition. RESULTS AND CONCLUSION:Based on DICOM data, three-dimensional finite element model of femur was constructed more quickly and precisely. The models were divided into 38 636 nodes and 201 422 units. The model included the parts of cortical and cancel ous bone. The biomechanical test results were accorded with the previous results, so the model could objectively reflect the real femur shape and biomechanical behavior with high precision. The Mimics software provided a simpler and effective method for the construction of femur model and improved the efficiency of modeling, and the three-dimensional finite element model based on DICOM data was accurate in shape and can be used for the normal research on biomechanical behavior of femur. The stress distribution analyzed with ABQUS 6.8 software is consistent with the clinical observation.
10.Observation of blood flow in verruca vulgaris using laser speckle contrast imaging before and after pulsed dye laser treatment
Chinese Journal of Dermatology 2016;(3):183-186
Objective To visualize blood flow changes in verruca vulgaris noninvasively with laser speckle contrast analysis (LSCA), and to evaluate the relationship of size and location of warts with efficacy of laser treatment. Methods Pulsed dye laser(PDL)was used to treat 30 verruca vulgaris lesions in 17 patients. In order to evaluate therapeutic effect of PDL, LSCA was performed to observe blood flow in warts and their surrounding normal skin, and to calculate speckle flow index (SFI)values before laser treatment, and at 10 minutes as well as on 3 weeks after laser treatment. Results Before PDL treatment, SFI values were significantly higher in warts than in their surrounding normal skin (11.600 ± 1.190 vs. 5.280 ± 0.481, t = 8.169, P < 0.01). Compared with those before the treatment, SFI values in warts significantly decreased at 10 minutes(3.112 ± 0.484, t = 4.407, P < 0.01)and on week 3(7.315 ± 1.083, t = 3.294, P < 0.01)after the treatment, and were significantly higher on week 3 than at 10 minutes (t = 4.646, P < 0.01). SFI values in surrounding normal skin significantly increased at 10 minutes after the treatment compared with those before the treatment (20.260 ± 2.063 vs. 5.296 ± 0.708, t = 6.770, P < 0.01), but were significantly lower on week 3 than at 10 minutes (4.941 ± 0.616, t = 6.964, P < 0.01). No significant difference was observed between SFI values in surrounding normal skin on week 3 after the treatment and those before the treatment (t = 0.378, P = 0.707). The efficacy of laser treatment was associated wart size and location. Changes of blood flow(|ΔSFI|)were significantly higher in warts measuring less than 0.5 cm2 in size than in those equal to or more than 0.5 cm2 (t = 2.287, P < 0.05), and significantly differed among warts at different sites (F =15.71, P < 0.01). The greatest changes of blood flow in warts were observed on fingers, followed by the dorsum of feet, toes, palms and soles and periungual areas. Conclusions Blood flow in verruca vulgaris is markedly increased compared with that in normal skin. PDL can clear verruca vulgaris by solidifying and gasifying capillaries. LSCA may be used to evaluate the efficacy of laser on verruca vulgaris more quantitively by monitoring regional blood flow.
