In order to make the computer own the knowledge about Chinese vehicle license plate segmentation and recognition, the paper put forward a set of algorithms about license plate segmentation and recognition. The algorithms are divided into four parts: image preprocessing, license plate location, license plate segmentation and character recognition. The aim of image preprocessing is quickly and easily location the license plate, so the image preprocessing algorithm is one of the important factors that affect total system performance. Because the algorithm of license plate location directly affects the accuracy of character segmentation and character recognition. So, the algorithm of license plate location is proposed according to characteristics of Chinese vehicle license plate. The algorithm of license plate segmentation uses the vertical projection method about license plate in this paper. According to the license plate segmentation character, the training model can be generated using tool of BPNN(back propagation neural network), which is the key of the character recognition algorithm about license plate. The results of experiment based the algorithms in the paper illustrate that accuracy rate of character recognition is very high, and the algorithms can fully meet the actual demand of automatic recognition. The algorithms can take advantage of the training model to perfectly realize recognition the license plate, and have application value in the real work. © 2016 IEEE.

Hypertensive patients in neurosurgery are becoming more common, which increased the risk of surgical stress response. Meanwhile, the relationship between hypertension and anesthesia methods is unclear on the stress response. The purpose of this study is to compare the effect of different anesthesia methods on high-sensitivity C-reactive protein (Hs-CRP), blood glucose, and leucocyte levels in neurosurgical patients with hypertension or normal. Eighty neurosurgical patients were randomly divided into 4 groups (n=20): balanced anesthesia group (A), balanced anesthesia with hypertension group (B), total intravenous anesthesia group (C), total intravenous anesthesia with hypertension group (D). The levels of Hs-CRP, blood glucose, leucocyte count, and neutrophil percentage and were detected at before anesthesia (T0), during anesthesia (T1), 2hours post anesthesia (T2), 24hours post anesthesia (T3). Patients with hypertension had higher Hs-CRP expression, blood glucose, and neutrophil percentage at time T0 than those of normal, but not leucocyte count. At time T3, patients with hypertension in D group had lower Hs-CRP expression than those in B group (P<0.01). Patients with normal in C group had lower Hs-CRP expression (P<0.01), blood glucose (P<0.05), and leukocyte count (P<0.05) than those in A group. Both hypertension history and anesthesia method had significant effects on the Hs-CRP expression, blood glucose, and leukocyte count. Total intravenous anesthesia decreases Hs-CRP expressions more efficiently than balanced anesthesia in neurosurgical patients with hypertension or normal. Moreover, total intravenous anesthesia can availably reduce the perioperative stress response by attenuating the increase of blood glucose and leukocyte count in normal tensive patients.

With the rapid development of nanoscience and nanotechnology, comprehensive evaluation of the potential toxicity especially the respiratory toxicity of nanomaterials, has attracted great research interest over the past few decades. A numerous previous reports have utilized intratracheal instillation to imitate the physiological inhalation exposure route of nanomaterials. However, because it is a non-physiological breathing process, intratracheal instillation has many problems when it is utilized to evaluate respiratory toxicity of nanomaterials. In this study, anatase titanium dioxide (TiO2) nanoparticles with a primary particle size of 20 nm was selected as a model nanomaterial. Its respiratory toxicity has been estimated by a whole-body exposure chamber. Mice were put in the whole-body exposure chambers with a relatively steady concentration (6.34 ± 0.22 mg m-3) of inhaled TiO2 nanoparticles. In the whole study these mice were exposed 8 h per day, for 3 weeks. Results showed that these TiO2 nanoparticles inhaled might drill through air-blood barriers, be metabolized by the liver and excreted by the urinary system. After mice had been exposed to TiO2 nanoparticles, H2O2 and maleic dialdehyde (MDA) in brain homogenate extracts had clearly increased. The white blood cell (WBC) count was decreased while platelet (PLT) and reticulocyte (Retic) counts increased significantly. At the same time, the prothrombin time (PT) of mice in the inhalation exposure group was shorter than the control group's. Furthermore, compared with the control group's, the levels of ALT, AST, BUN and CREA in the inhalation exposure group were elevated. Given the whole body exposure method is a physiological exposure route, the results reported in this work should be more suitable for evaluation of the respiratory toxicity of nanomaterials.

Abstract A simple, rapid, selective in situ ionic liquid dispersive liquid-liquid microextraction and determination of Au(III) by flame atomic absorption spectrometry has been first proposed for the extraction of Au(III). In the developed method, NH4PF6 aqueous solution was added to the sample solution containing [CnMIM]Br to form a water-immiscible ionic liquid, [CnMIM]PF6 as extraction solution. The formation of hydrophobic ionic liquid and subsequent extraction of gold(III) were achieved in one step without the need for dispersive solvent and chelating agent. The effects of various experimental parameters on gold extraction were investigated in detail. At optimum conditions, the linear range of 0.9-400 ng/mL of Au(III), the limit of detection 0.13 ng/mL for Au(III) along with enrichment factors of 23.7 and the extraction capacity of 97.5 mg/g by the proposed method for Au(III) were obtained. The proposed method was applied to extract trace amounts of Au(III) in water samples with satisfactory results. © 2015 Iranian Chemical Society.

Objective: The aim of the study was to investigate the apoptosis induced by piperlongumine on human breast adenoma MDA-MB-231 cells and the mechanism involved. Methods: Human breast adenoma MDA-MB-231 cells line was cultured in vitro. The inhibitory effect of piperlongumine on the proliferation of human breast adenoma MDA-MB-231 cells was measured by CCK-8 assay. Distribution of cell cycle was analyzed by flow cytometry. The apoptosis rates of MDA-MB-231 cells were measured using Annexin V/PI staining. The flow cytometry with the probe of DCFH-DA was used to detect the intracellular reactive oxygen species levels. Western blot was used to explore the protein expression of Bcl-2 and Bax. Results: The CCK-8 assay showed that piperlongumine had an inhibiting effect on the proliferation of MDA-MB-231 cells in a concentration- and time-dependent manner. MDA-MB-231 cells were markedly arrested at G0/G1 phase after treatment of piperlongumine. Piperlongumine induced apoptosis of MDA-MB-231 cells obviously. The level of intracellular reactive oxygen species was increased in a dose-dependent manner. The antioxidant N-acetyl-L-cystein inhibited the apoptosis of cells and the level of intracellular reactive oxygen species was also decreased. By Western blot analysis, we found the expression of Bax was up-regulated whereas that of Bcl-2 was down-regulated in a concentration-dependent manner. Conclusion: Piperlongumine possesses a significant function for inhibiting proliferation, arresting cells at G0/G1 phase and inducing apoptosis of MDA-MB-231 cells, which seems to be associated with the increased generation of intracellular reactive oxygen species as well as the down-regulation of Bcl-2 and up-regulation of Bax. © 2013 Springer-Verlag Berlin Heidelberg.

In order to solve the changing contents and the simple grouping of packet in current watermarking technologies, a new watermarking scheme was proposed based on theoretical analysis and calculation. The packet delay was modulated subtly in the interval-based changing slot network stream watermarking scheme. The code division multiplexing was used to extend the watermark information and improve the error correction ability. To test and verify the performance of new technology, various network environments were simulated to complete many tests, and the detection rates were calculated by two ways. The experimental results show that the detection rate of new scheme is increased by 28% than the original group packet when the jitter average is more than 6 ms. When the jitter average is less than 10 ms, the mean detection error rate of new technology is less than 0.49, while the rate of original way is more than 0.5. The comparison shows that the new technology can improve the detection rate clearly with high performance. ©, 2015, Journal of Jiangsu University (Natural Science Edition). All right reserved.

Aims Luteolin is a falconoid compound that has an antioxidant effect, but its contribution to ROS-activated MAPK pathways in ischemia/reperfusion injury is seldom reported. Here, we have confirmed that it exhibits an antioxidant effect in myocardial ischemia/reperfusion injury (MIRI) by inhibiting ROS-activated MAPK pathways.Main methods We exposed rat hearts into the left anterior descending coronary artery (LAD) ligation for 30 min followed by 1 h of reperfusion. Observations were carried out using electrocardiography; detection of hemodynamic parameters; and testing levels of lactate dehydrogenase (LDH), creatine kinase (CK), total superoxide dismutase (T-SOD), and malondialdehyde (MDA). Mitogen-activated protein kinase (MAPK) pathway was measured by western blot and transmission electron microscopy was applied to observe the myocardial ultrastructure. Rat H9c2 cell in 95% N2 and 5% CO2 stimulated the MIRI. Oxidation system mRNA levels were measured by real-time PCR; mitochondrial membrane potential and apoptosis were measured by confocal microscopy and flow cytometry; western blot analysis was used to assay caspase-3, -8, and -9 and MAPK pathway protein expression; the MAPK pathway was inhibited using SB203580 (p38 MAPK inhibitor) and SP600125 (c-Jun NH2-terminal kinase inhibitor) before H9c2 cells were exposed to hypoxia/reoxygenation injury to show the modulation of the changes in ROS generation, cell viability and apoptosis.Key findings In vivo, luteolin can ameliorate the impaired mitochondrial morphology, regulating the MAPK pathway to protect MIRI. In vitro, luteolin can affect the oxidation system, mitochondrial membrane potential and MAPK pathway to anti-apoptosis.Significance These results reveal a ROS-MAPK mediated mechanism and mitochondrial pathway through which luteolin can protect myocardial ischemia/reperfusion injury. © 2014 Elsevier B.V.
