Objective To investigate psychology state of AIDS-phobia population. Methods 50 AIDS-pho-bia patients and 50 healthy controls were enrolled and tested with SCL-90,EPQ, LES and social support scale. Results Scores of SCL-90 in AIDS-phobia patients are significantly more than those in controls. Scores of anxiety, depres-sion,compulsion,dread and somatization in AIDS-phobia patients are significantly more than those in controls. Scores of negative life event scale in AIDS-phobia patients are significantly more than those in controls. Scores of positive life event scale in AIDS-phobia patients are significandy less than those in controls. Scores of social support scale in AIDS-phobia patients are significantly less than those in controls. Conclusions Anxiety, depression, compulsion, dread and somatization are primary clinical manifestation of AiDS-phobia. Personal character,negative life event and lack of social support might be nosogenesis correlated with AIDS-phobia.

Hilbert-Huang transform (HHT) is a new time-frequency analytic method to analyze the nonlinear and the non-stationary signals. The key step of this method is the empirical mode decomposition (EMD), with which any complicated signal can be decomposed into a finite and small number of intrinsic mode functions (IMF). In this paper, a new EMD based method for suppressing the cross-term of Wigner-Ville distribution (WVD) is developed and is applied to analyze the epileptic EEG signals. The simulation data and analysis results show that the new method suppresses the cross-term of the WVD effectively with an excellent resolution.

The automatic spike detection in EEG is significant in both diagnosing illness and alleviating the heavy labour force of the doctor. This paper proposes a new EMD based method to complete spike detection. It decomposes a signal into a few intrinsic mode functions (IMF), and then applies the nonlinear energy operator (NEO) to the first IMF to complete the automatic detection. Sufficient results are obtained by applying this method to the spike detection of the simulation signal and the real epileptic EEG signal.

To reveal the pharmacological mechanism of 3-arylcoumarin derivative 3-(4′-hydroxyphenyl)-6-hydroxycoumarin (SJ-6) against vascular calcification, advanced glycation end products (AGEs) were used to induce the calcification of human aortic vascular smooth muscle cells (HCASMCs), and calcification was identified by alizarin red staining and quantification.The effects of SJ-6 on alkaline phosphatase (ALP) activity, cell proliferation rate, calcium content, and total reactive oxygen species (ROS), superoxide dismutase (SOD), AGEs, and tetra methylethlene diamine proteinase factor-α (TNF-α), interleukin-6 (1L-6), interleukin-β (1L-β), runt-related transcription factor 2 mRNA (Runx2 mRNA), the receptor of advanced glycation endproducts (RAGE), nuclear factor kappa-B (NF-κB), napdh oxidase-1 (NoX-1), protein kinase C(PKC), protein kinase b(AKT), p38 mitogen-activated protein kinase (p38 MAPK), and smooth muscle actin-α (SMA-α) protein expression were determined.According to our results, SJ-6 significantly decreased AGEs content, ALP activity, intracellular calcium content, ROS content, Runx2 mRNA and inflammatory factors TNF-α, 1L-6 and 1L-β (P < 0.05) and increased SOD content (P < 0.01), with similar to those of the positive control drug aminoguanidine hydrochloride (AGH).Therefore, we investigated the pharmacological mechanism of compound SJ-6, which was found to significantly inhibit the expression of RAGE, NF-κB, NoX-1, PKC, Akt, p-p38 and other essential signaling proteins in the calcified cell model (P < 0.01) and increas the expression of smooth actin SMA-α (P < 0.01).SJ-6 inhibits vascular calcification by inhibiting oxidative stress and the expression of AGEs/RAGE, Akt/PKC and NF-κB signaling pathways, suggesting that it may be a novel drug for the treatment of vascular calcification.

The WUSCHEL related-homeobox (WOX) family is one of the plant-specific transcription factor families, playing important roles in plant growth and development. In this study, 51 WOX gene family members were identified from the genome data of Brassica juncea by searching and screening with HUMMER, Smart and other software. Their protein molecular weight, amino acids numbers, and isoelectric point were analyzed by using Expasy online software. Furthermore, bioinformatics software was used to systematically analyze the evolutionary relationship, conservative region, and gene structure of the WOX gene family. The mustard WOX gene family was divided into three subfamilies: ancient clade, intermediate clade, and WUS clade/modern clade. Structural analysis showed that the type, organization form and gene structure of the conservative domain of WOX transcription factor family members in the same subfamily were highly consistent, while there was a certain diversity among different subfamilies. 51 WOX genes are distributed unevenly on 18 chromosomes of mustard. Most of the promoters of these genes contain cis acting elements related to light, hormone and abiotic stress. Using transcriptome data and real-time fluorescence quantitative PCR (qRT-PCR) analysis, it was found that the expression of mustard WOX gene was spatio-temporal specific, among which BjuWOX25, BjuWOX33, and BjuWOX49 might play an important role in the development of silique, and BjuWOX10, BjuWOX32, and BjuWOX11, BjuWOX23 respectively might play an important role in the response to drought and high temperature stresses. The above results may facilitate the functional study of mustard WOX gene family.
