0.05). However, there were quite improvements of survival rate and survival quality for cervical adenocacinoma. Their 5-year survival rates were 91% and 33% (P

Objective To study the regional homogeneity (ReHo) of default-mode network (DMN) in patients with minimal hepatic encephalopathy (MHE) with resting state fMRI.Methods Eighteen MHE patients and eighteen healthy controls (HC) underwent standard resting state fMRI scan.The resting state fMRI data were analyzed with the ReHo method to observe the changes of DMN in the patients in contrast to the controls.Results Compared to healthy controls,MHE patients showed lower ReHo in bilateral MPFC/anterior cingulate cortex(V=13.257 cm3;MNI coordinates=3,24,66;t=-3.493 7),bilateral precuneus/posterior cingulate cortex(V=4.752 cm3;MNI coordinates=9,-54,45;t=-2.634 1),while higher ReHe in right medial prefrontal cortex(V=5.049 cm3;MNI coordinates=21,63,6;t=4.017 5).Conclusion In MHE patients,there is abnormal neuron activation in the widespread DMN regions under resting state, which indicated abnormal spontaneous activity consistency within DMN and endogenous brain function injury in MHE patients.ReHo can be used to observe DMN changes in MHE patients.

OBJECTIVE: To observe the clinical effects of Xinfeng Capsules (XFC), a traditional Chinese medicine for invigorating the spleen to resolve dampness and dredging collaterals, on patients with rheumatoid arthritis (RA) and anemia, and to investigate its mechanism. METHODS: Forty patients with RA and anemia were divided into three groups: XFC-treated group (n=20), Tripterygium glycosides Tablets (TGT)-treated group (n=10) and methotrexate (MTX)-treated group (n=10). The patients in each group took corresponding medicine for three months. The response rates of the three groups were evaluated after treatment. The general symptoms and specific signs and symptoms of RA were observed before and after the treatment. The indexes of blood routine examination and some other laboratory indexes such as erythrocyte sedimentation rate (ESR), and blood levels of rheumatoid factor (RF), iron, C-reaction protein (CRP), immunoglobins (Ig), complements 3 and 4, tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10) and erythropoietin (EPO) were all examined and compared before and after treatment. RESULTS: The total response rate in the XFC-treated group was similar to those both in the TGT-treated and MTX-treated groups. The effects on relieving specific symptoms of RA in the three groups were also similar. The ESR and serum levels of RF, CRP, IgG, IgA and IgM were all decreased after treatment as compared with those before treatment in the three groups, and there were no significant differences among those laboratory indexes in the three groups after treatment. The XFC displayed more obvious effects on improving the general symptoms of patients with RA and anemia, increasing the blood levels of hemoglobin, iron and IL-10, while decreasing the serum level of TNF-alpha and regulating the serum EPO level, as compared with those in the TGT-treated and MTX-treated groups. CONCLUSION: The XFC for invigorating the spleen to resolve dampness and dredging collaterals was developed on the basic principle of regulating spleen. It can obviously improve the symptoms and laboratory indicators of RA. Such effects may be related to maintaining the balance of cytokines, regulating the serum level of EPO and increasing the serum iron level in patients with RA and anemia.

DNA microarray has become an essential medical genetic diagnostic tool for its high-throughput, miniaturization and automation. The design and selection of oligonucleotide probes are critical for preparing gene chips with high quality. Several sets of probe design software have been developed and are available to perform this work now. Every set of the software aims to different target sequences and shows different advantages and limitations. In this article, the research and development of these sets of software are reviewed in line with three main criteria, including specificity, sensitivity and melting temperature (Tm). In addition, based on the experimental results from literatures, these sets of software are classified according to their applications. This review will be helpful for users to choose an appropriate probe-design software. It will also reduce the costs of microarrays, improve the application efficiency of microarrays, and promote both the research and development (R&D) and commercialization of high-performance probe design software.

During placental development, oxygen environment is not only critical for trophoblasts migration and invasion, but also fundamental for appropriate placental perfusion. Cysteine-rich 61 (Cyr61, CCN1) was expressed in the extravillous trophoblasts (EVTs) and decreased in preeclampsia. Its regulatory properties in human first-trimester extravillous trophoblast cell line (TEV-1 cells) upon a low oxygen tension were investigated. The present study examined functional changes involved in adaptation to hypoxia of the TEV-1 cells, using cobalt chloride (CoCl(2)) as hypoxic mimic. It was found that hypoxia inhibited growth of TEV-1 cells and induced the increase of cell apoptosis (P<0.05). The Cyr61 expression in human EVTs was transcriptionally induced by CoCl(2). Inappropriate EVTs apoptosis has been implicated in the failure of trophoblasts to fully invade and modify the uterine environment and Cyr61 down-regulation, potentially leading to preeclampsia.
