AIM: To investigate the expression pattern of plasma long noncoding RNAs (lncRNAs) in Chrohn’s disease (CD) ***: Microarray screening and qRT-PCR verification of lncRNAs and mRNAs were performed in CD and control subjects, followed by hierarchy clustering, GO and KEGG pathway analyses. Significantly dysregulated lncRNAs were categorized into subgroups of antisense lncRNAs, enhancer lncRNAs and lincRNAs. To predict the regulatory effect of lncRNAs on mRNAs, a CNC network analysis was performed and cross linked with significantly changed lncRNAs. The overlapping lncRNAs were randomly selected and verified by qRT-PCR in a larger ***: Initially, there were 1211 up-regulated and 777 down-regulated lncRNAs as well as 1020 up-regulated and 953 down-regulated mRNAs after microarray analysis; a heat map based on these results showed good categorization into the CD and control groups.

The rational design of double active sites system is vital for constructing high-efficiency iron sulfides electrocatalysts towards hydrogen evolution reaction(HER) in alkaline media. However, it remains a challenge to controllably create the high-density interface of double sites for optimal synergistic ***, we reported a simple chemical oxidation-induced surface reconfiguration strategy to obtain the interface-rich Fe_(3)O_(4)-FeS nanoarray supported on iron foam(Fe_(3)O_(4)-FeS/IF) using FeS nanosheets as precursors. The abundant Fe_(3)O_(4)-FeS interfaces could improve the dispersion of active sites and facilitate the electron transfer, leading to enhanced hydrogen evolution efficiency. And meanwhile, by altering the oxidation temperature, the content of S and O could be effectively controlled, further achieving the ratio optimization of Fe_(3)O_(4)to FeS. Synchrotron-based X-ray absorption near-edge structure, X-ray photoelectron spectroscopy and ultraviolet photoemission spectroscopy consistently confirm the changes of electronic structure and d-band center of Fe_(3)O_(4)-FeS after chemical oxidation. Consequently, Fe_(3)O_(4)-FeS/IF exhibits excellent alkaline HER activity with a low overpotential of 120.8 mV to reach 20 mA cm^(-2),and remains stable ranging from 10, 20 to 50 mA cm^(-2) for each 20 h, respectively. Therefore, the facile and controllable chemical oxidation may be an effective strategy for designing high-density interfaces of transition metal-based sulfides towards alkaline HER.

The heterojunction interfacial modulation of FeP is an effective strategy to regulate the intrinsic activity and stability, which is a major challenge to promote the industrial application of FeP-based electrocatalysts. Herein, hollow Fe_(4)C/FeP box with heterojunction interface and carbon armor is successfully synthesized, which can expose numerous active sites and protect catalyst from corrosion. Electrochemical measurements show that Fe_(4)C/FeP exhibits excellent hydrogen evolution activity and stability. It only needs 180 mV to achieve the current density of 10 mA cm^(-2). The high-activity may be due to the synergistic effects of porous framework, graphitic carbon coating and heterojunction structure of FeC and FeP, which optimize the electronic structure and accelerates electron transfer. In addition, the target catalyst can withstand 5000 cycles of CV testing without significant change in properties. The excellent stability may be attributed to the graphitic carbon coating as the armor that can prevent the catalyst from corrosion of electrolyte. This work may provide a synthetic approach to produce a series of carbon-coated and heterojunction structure of transition metal phosphides for water splitting.

BACKGROUND: Most physicians in China may neglect portal vein thrombosis(PVT) in clinical practice. In fact, portal vein thrombosis is an important cause of non-cir-rhotic portal hypertension. As the diversity of its clinical manifestations, misdiagnosis is common if we don t bear PVT in mind during differential diagnosis. Therefore, we systematically reviewed PVT in terms of etiology, patho-physiology, pathology, clinical manifestations, and management. DATA SOURCES: An English-language literature search (from 1980 to 2004 ) was performed using Medline and Medscape, and articles closely related to PVT were selected. RESULTS: PVT is the second cause of portal hypertension after liver cirrhosis in western countries. Liver cirrhosis and hepatocellular carcinoma, ultra-abdominal infection, thrombophilic disorders including myeloproliferative diseases are strongly associated with the development of PVT. Liver transplantation is an emerging etiological factor of PVT with the development and wide use of this technique. Gastrointestinal bleeding resulted from esophageal varices, abdominal pain, splenomegaly and hypersplenism and asci-tes are common manifestations of PVT. However there are differences in etiological and clinical presentations between children and adults. Diagnosis of PVT depends on ima-ging-studies including Doppler ultrasonography, computed tomography ( CT), magnetic resonance imaging ( MRI), and portography. Endoscopic therapy is recommended for variceal bleeding in PVT. Anticoagulant treatment for acute PVT is widely accepted in western countries. CONCLUSIONS: PVT may be unrecognized as the clinical manifestations are unspecific. Misdiagnosis and delayed treatment can lead to poor prognosis. Systematical collection of epidemiological and clinical data about PVT is necessary in China.
