Objective To investgate the value of various parameters obtained from monoexponential, biexponential, and stretched exponential diffusion?weighted imaging models in the differential diagnosis of breast lesions. Methods A retrospective study performed in 54 patients with pathologically confirmed malignant tumors(n=30), benign lesions(n=34) and normal fibroglandular tissues (n=30). All patients underwent T1WI, T2WI, dynamic enhancement and diffusion weighted MRI with multi?b values at a 3.0 T magnetic resonance imaging unit. All parameters were measured at a workstation. ADC was calculated by using monoexponential analysis(b=0, 800 s/mm2). Slow apparent diffusion coefficient (ADC?slow), fast apparent diffusion coefficient (ADC?fast), and perfusion fraction (f) were calculated using the biexponential model. Distributed diffusion coefficient (DDC) and water molecular diffusion heterogeneity index (α) were obtained from diffusion?weighted images using the stretched exponential model. All parameters were statistically compared among normal fibroglandular tissues, benign lesions and malignant tumors using Kruskal?Wallis rank sum test. Mann?Whitney U test were used for further comparisons between specific group pairs. ADC values were compared with ADC?slow and DDC for different groups by paired Wilcoxon test. Correlations between ADC?value, ADC?slow and DDC were assessed by using Spearman rank correlation coefficient. Receiver operating characteristic curve was used to analyze and compare the ability of these parameters in differentiation of benign and malignant breast lesions. Results The ADC, ADC?slow, f, DDC and α values were significantly different among the normal fibroglandular tissues, benign tumors and malignant tumors (P<0.05). Further differential comparisons of the four parameters between each pair showed that the ADC, ADC?slow, f, DDC and α values were significantly lower in malignant tumors than both in normal fibroglandular tissues and benign tumors(P<0.016 7). The ADC values of normal fibroglandular tissues, benign tumors and malignant tumors were significantly higher than ADC?slow and DDC (P<0.05). The f and DDC had higher area under the receiver operating characteristic curve (0.688 and 0.657 respectively). The optimal cutoff values for ADC, ADC?slow, f, DDC and α were 1.235 × 10-3mm2/s, 0.428 × 10-3mm2/s, 57.8%, 1.175 × 10-3mm2/s and 0.721, respectively. Theαvalue showed higher specificity (65.5%) and the f value had higher sensitivity (82.9%). Conclusion The parameters derived from biexponential and stretched exponential DWI could be helpful for differentiation between benign and malignant breast tumors.

The microfluidic channels integrated with microring resonator were designed. The salt coalescence on chip surface caused by liquid volatilization in open environment was avoided and only 30 μL of reaction solution was consumed. These channels significantly reduced the experiment cost. The design, fabrication and characterization of a highly sensitive and label-free silicon-on-insulator (SOI) microring optical resonator integrated with the microfluidic channels were demonstrated. The radius of the microring was 5 μm and the straight waveguide with a width of 450 nm was employed in the microring resonator. The microring resonator device had many advantages such as high sensitivity, label-free and real-time detection. Using different concentrations of ethanol solution with known refractive indices, the refractive index detection sensitivity was 76.09 nm/RIU and the volume refractive index detection limit was 5.25×10Symbolm_4 RIU. We also demonstrated the label-free quantitative specific detections of human immunoglobulin G (IgG) solutions using an antibody-modified microring resonator by measuring the resonance wavelength shift resulting from refraction index changes causing by the immobilization of antibodies and specific recognition between antibodies and antigens, respectively. The results showed that the microring optical resonator could real-time monitor the reaction between biological molecules, the resonator could be used in the quantitative detection and biological sensing.

Objective To explore the expression of livin and survivin and its correlation with caspase-3 and clinicopathology in breast cancer. Methods We examined paraffin-embedded archival specimens from 76 cases of malignant breast tumor and 17 cases of benign breast disease for the expression of livin,survivin and caspase-3 with immunohistochemistry. The relationship of livin and survivin expression with caspase-3 and clinicopathological characteristics was analyzed. Results The positive rates of livin and survivin protein expression were increased gradually in normal breast tissues,livin and survivin proliferating disease,preinvasive carcinoma and invasive breast carcinoma,while the caspase-3 protein expression was significantly decreased. The expression of livin and survivin was negatively correlated with that of caspase-3 in the four groups (P0.05). The expression of survivin was related to lymph node metastasis and tumor size (P0.05). Conclusion Livin and survivin may play an important role in accelerated tumor proliferation by inducing caspase-3 to inhibit apoptosis in breast carcinoma. Livin may be more correlated with carcinogenesis in young patients while survivin may promote metastasis and invasion in breast carcinoma.
