This review surveys the advances of microvalves, micropumps, and micromixers within PCR microfluidic chips over the past ten years. First, the types of microvalves in PCR chips are discussed, including active and passive microvalves. The active microvalves are subdivided into mechanical (thermopneumatic and shape memory alloy), non-mechanical (hydrogel,(More)
—The attribute reduction based on rough set usually reflects the essence of information table and it is the key content of rough set theory. With the analysis of the difference degree between equivalence classes or tolerance classes based on rough set theory, a measure for the importance of attributes was introduced. And based on the measure, a method of(More)
This study was performed to investigate the relationship between the abundance of pathogenic gut microbes in Chinese patients with inflammatory bowel disease (IBD) and disease severity.We collected clinical data and fecal samples from 47 therapy-naive Chinese patients with ulcerative colitis (UC), 67 patients with Crohn disease (CD), and 48 healthy(More)
OBJECTIVE This study investigated the incidence, risk factors, and clinical characteristics of Clostridium difficile-associated diarrhea (CDAD) in Chinese patients. METHODS Fecal specimens of patients with antibiotic-associated diarrhea (AAD) were collected to test C. difficile toxin A and B using enzyme-linked fluorescent assay to identify CDAD. By(More)
Neuronal PAS domain protein 3 (NPAS3) and VGF (VGF Nerve Growth Factor (NGF) Inducible) are important for neurogenesis and psychiatric disorders. Previously, we have demonstrated that NPAS3 regulates VGF at the transcriptional level. In this study, VGF (non-acronymic) was found regulated by NPAS3 in neuronal stem cells. However, the underlying mechanism of(More)
Methicillin-resistant Staphylococcus aureus (MRSA) is an increasing cause of serious infection, both in the community and hospital settings. Despite sophisticated strategies and efforts, the antibiotic options for treating MRSA infection are narrowing because of the limited number of newly developed antimicrobials. Here, four newly-isolated MRSA-virulent(More)
OBJECTIVES Ubiquitin carboxy-terminal hydrolase-L1 (UCH-L1) has been established as a potential biomarker of neuronal damage. There is not much information about the effects of white matter lesions (WMLs) on serum and urine UCH-L1 levels in white matter disease patients. This study was aimed to assess whether serum or urine UCH-L1 levels are a reliable(More)
