Purpose: The rat cervicitis model was established with 20% phenol glue to explore the therapeutic effect of Kangfuxiaomi shuan II on rat cervicitis and its mechanism. Methods: After modeling, the rats were treated with Shuangzuotai suppository (37.84 mg/kg), Kangfuxiaoyan shuan (205.6 mg/kg) and Kangfuxiaomi shuan II (40, 80, 160 mg/kg). The histopathological changes and injury degree of cervix in rats were evaluated by vulvar inflammation score and organ index. The therapeutic effect of Kangfuxiaomi shuan II on cervicitis was evaluated by detecting the levels of copper-protein (CP), C-reactive protein (CRP), Rat interleukin 6 (IL-6), superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and epidermal growth factor (EGF), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in cervical tissue. Results: Compared with the model group, the vulvar inflammation score and cervical index of rats in other groups decreased significantly (P

Research on evaluation for steganalysis based on image lags back the development of Information Hiding which will hinder the development of it. The evaluation system for steganalysis based on image which includes index system, testing system and comprehensive testing system is proposed. The common steganalysis tools are evaluated using the system, whose feasibility is proved both in theory and experiment.

The construction of Electronic Nose system and associated signal processing methods were introduced .Then special references to applications to dairy products, such as the classification of different milk, the milk with different shelf-lives, flavor quality evaluation, antibiotics resedues detection and quality control were discussed. The results show that the quality of dairy products can be evaluated effectively using Electronic Nose system. The development trends of Electronic Nose are presented.

β,β-dimethylacrylshikonin (DA) is a natural naphthoquinone derivative compound of Lithospermum erythrorhizon with various biological activities. The present study aimed to investigate the inhibitory effects and underlying mechanisms of DA in human breast carcinoma MCF-7 cells. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed that DA inhibited the proliferation of MCF-7 cells in a dose- and time-dependent manner. The half maximal inhibitory concentration of DA with regard to the proliferation of MCF-7 cells was 0.050±0.016 mM. The characteristics of cell apoptosis, including cell shrinkage, nuclear pyknosis and chromatin condensation, were all observed in DA-treated cells. DA decreased the expression levels of Bcl-2 and increased the expression of Bax and caspase-3 compared with those in the control. DA inhibited the activity of the nuclear factor (NF)-κB pathway, by downregulating the expression of the p65 subunit, and inhibited the Iκb phosphorylation. DA inhibits the proliferation of MCF-7 cells in vitro by inducing apoptosis through the downregulation of Bcl-2, upregulation of Bax and partial inactivation of the NF-κB pathway.

A novel benchmark for efficiency evaluation of steganalysis is presented in this paper. The efficiency metric reflects the detection accuracy of steganalysis, which is an important index to evaluate the performance of steganalysis schemes. The main idea is to evaluate efficiency in terms of KL divergence between the distributions of cover and stego images. The three stages in the processing of steganalysis are analyzed, on the basis of which metric E is measured by relative performance. The common LSB based steganalysis schemes are evaluated by metric E. Experimental results show that the index E given here can measure the efficiency of steganalysis schemes effectively.

The imperceptibility of steganography is one of the most important measures that evaluate the performance of the steganography algorithm. The global evaluation model PSNR which is widely used by most researchers can’t evaluate the performance of steganography algorithm effectively. Lacking of researches on imperceptibility for color stego image is even serious. Based on HVS model and detailed analyzing of color space, color masking weight is computed and then imperceptibility metric CYIQ for color stego image is proposed in the paper. Experimental results show that CYIQ outperforms global PSNR, which reflects the color masking, luminance masking and texture masking of HVS, and CYIQ can be used to measure the imperceptibility of steganography methods.

It is important to identify the severity of acute pancreatitis (AP) in the early course of the disease. Clinical scoring systems may be helpful to predict the prognosis of patients with early AP; however, few analysts have forecast the accuracy of scoring systems for the prognosis in hyperli
