Background: Chronic hepatitis B virus (HBV) infection, which can lead to hepatic disease, has become a critical national healthcare problem, and many people die each year as a result of HBV infection and its complications. Although microRNA-33a (miR-33a) is a novel modulator of lipid and cholesterol metabolism, the role of miR-33a in the hepatic fibrogenesis is still unknown. Here, we aimed to explore the roles and mechanisms of miR-33a in liver fibrosis. Methods: miR-33a expression in whole liver and serum samples was measured from chronic hepatitis B (CHB) patients by quantitative real-time PCR (qRT-PCR). In addition, different murine hepatic fibrosis models were produced to consolidate the results in human tissue. Human and murine primary liver fibrosis-associated cells were isolated and treated with transforming growth factor-β1 (TGF-β1). Results: miR-33a expression levels in liver tissue significantly increased with a fibrosis progression manner in the human liver. Furthermore, serum miR-33a levels associated positively with progressing process of hepatic fibrosis. miR-33a was in particular increased in hepatic stellate cells (HSC) than other liver fibrosis-associated cells. Stimulation of HSCs with TGF-β1 leads to a critical increase of miR-33a. Increasing miR-33a levels increased (whereas inhibiting miR-33a weakened) the activation role of TGF-β1 in LX-2 cells, which might be a potential mechanism through moderating Smad7 expression. Conclusions: miR-33a may be a novel marker for HSC activation and hepatic fibrosis progress, suggesting a new therapeutic target in liver fibrosis. © 2014, Springer Japan.

An effective approach to synthesize methacrylate-based hybrid monoliths was carried out by photopolymerization and the properties of the obtained monoliths mixed with mult-wall carbon nanotube (MWNT) were studied in this paper. The prepared hybrid materials with MWNT in the range of 0-5% total weight of monomers were characterized by Fourier transform infrared spectra, thermo-gravimetric analysis (TGA), and mercury intrusion porosimetry, respectively. Moreover, their porosities were evaluated by the determination of flow rate for different prepared monolithic capillaries. The results showed that the monoliths with more MWNT (1-5%) possessed larger pore sizes between 1-10 μm. The hybrid monoliths have the potential advantages including stronger hydrophobic properties and less resistance for the application of reversed phase liquid chromatography in the micro-column separation. © (2014) Trans Tech Publications, Switzerland.

A combination process of cellulosic ethanol wastewater treatment was described. This process includes iron-carbon micro-electrolysis-Fenton, UASB and MBR. Through the process, we'll get an exploration of engineering design operation parameters and pollutant removal mechanism. Test results show that if the wastewater have 5 hours' micro response, 36 hours to stay on the USAB and 25 hours to stay in the membrane bioreactor, after the flocculation decollating, the COD and ammonia nitrogen indexes of the wastewater have all reached the discharge standard of the Discharge Standard of Water Pollutants for Fermentation Alcohol and Distilled Spirits Industry (GB 27631-2011), and the effect of the operation is stable, cost is low. © (2013) Trans Tech Publications, Switzerland.

This paper is about the term as used in calculus.The derivative of a function of a real variable measures the sensitivity to change of a quantity (a function or dependent variable) which is determined by another quantity (the independent variable). It is a fundamental tool of calculus. This paper is based on the application of derivative in the field of manufacturing and mathematical modeling. © (2014) Trans Tech Publications, Switzerland.

An in-situ polymerization method was used for the preparation of a novel stir bar based on neodymium magnet (Nd2Fe14B) powders. The processes were carried out by several steps including the enwrapping of Nd2Fe14B, the modification of the enclosed Nd2Fe14B, and the form of organic polymers on the surface of the modified powders. It was successfully used to enrich the plasticizers in water sample by stir bar sorptive extraction (SBSE). The experimental conditions for SBSE, such as the choice of extraction sorvents, salt concentration, extraction and desorption time were optimized in detail. Coupled to high performance liquid chromatography (HPLC), the recoveries of dibutyl phthalate (DBP), dimethyl phthalate (DMP), diethyl phthalate (DEP) were 89.2%~92.1%, 91.9%~96.6% and 94.3%~96.7%, respectively; the linear relationships between the concentration 5 μg/L and 800 μg/L for DBP were obtained; the limits of detection ranged from 0.09 μg/L to 0.21 μg/L in the optimal conditions. © (2014) Trans Tech Publications, Switzerland.

We take university library as an example to mine association rules from circulation records in university libraries. To satisfy the requirement of information service in libraries, a mining algorithm is presented. This paper using association rule mining techniques to find law from the library borrowed document, and recommendation service is found by these rules. Furthermore, a recommendation service model which is applied to offer recommendation service is introduced. © 2016 IEEE.

The rise of wavelet analysis in applied mathematics is due to its applications and the flexibility. We introduce vector-valued wave wraps with multi-scale dilation factor for space L2 (R2 C2), which is the generalization of univariate wavelet packets. A method for constructing a sort of orthogo- nal vector-valued wavelet wraps in three-dimensional space is presented and their orthogonality traits are characterized by virtue of iteration method and time-frequency analysis method. The orthog- onality formulas concerning these wave packets are established. Moreover, it is shown how to obtain new Riesz bases of space L2 (R3,Cs) from these wave wraps. The notion of multiple pseudo fames for subspaces with integer translation is proposed. The construction of a generalized multiresolution structure of Paley-Wiener subspaces of L2 (R2) is investigated. The pyramid decomposition scheme is derived based on a generalized multiresolution structure. © (2014) Trans Tech Publications, Switzerland.

Aim: To explore the effect of nursing intervention on mental and physical health in patients with rectal cancer after Miles operation. Methods: One hundred and six patients with rectal cancer were randomly divided into two groups. The control group received routine nursing intervention, and the experiment group received comprehensive nursing intervention on the basis of routine nursing intervention. Three and six months after discharge, patients were assessed using the exercise of self-care agency (ESCA) scale and the symptom checklist 90 scale. Results: The scores of ESCA, self-care skills, self-nursing responsibility, self-concept and the scores of health knowledge in the two groups were significantly higher at 6 mo after discharge than at 3 mo (experiment group: 127.71 ± 14.17 vs 96.01 ± 13.33, 33.99 ± 3.66 vs 26.98 ± 4.11, 21.96 ± 3.68 vs 17.89 ± 3.12, 25.65 ± 3.71 vs 18.63 ± 4.20, 35.09 ± 7.58 vs 30.95 ± 5.39; control group: 121.06 ± 11.27 vs 91.30 ± 10.18, 29.86 ± 2.13 vs 21.09 ± 3.16, 18.96 ± 2.00 vs 14.73 ± 2.09, 21.96 ± 4.15 vs 16.38 ± 3.03, 31.94 ± 4.79 vs 26.33 ± 4.05, P < 0.05 for all); these parameters at 3 and 6 mo were significantly higher in the experiment group than in the control group (P < 0.05 for all). The scores of somatization, obsessive-compulsive symptoms, interpersonal relationship, depression, anxiety, sensitivity, terror, bigotry and psychotic symptom in the two groups were significantly lower at 6 mo after discharge than at 3 mo (experiment group: 1.48 ± 0.45 vs 3.32 ± 0.47, 1.54 ± 0.59 vs 3.05 ± 0.52, 1.38 ± 0.77 vs 2.92 ± 0.75, 1.57 ± 0.46 vs 3.06 ± 0.48, 1.44 ± 0.52 vs 2.95 ± 0.66, 1.29 ± 0.51 vs 2.49 ± 0.50, 1.20 ± 0.53 vs 2.74 ± 0.55, 1.38 ± 0.41 vs 2.66 ± 0.44, 1.28 ± 0.42 vs 2.71 ± 0.47; control group: 1.86 ± 0.28 vs 4.34 ± 0.43, 1.98 ± 0.56 vs 4.05 ± 0.49, 1.68 ± 0.66 vs 3.91 ± 0.68, 2.07 ± 0.62 vs 4.03 ± 0.57, 2.03 ± 0.73 vs 3.94 ± 0.69, 1.67 ± 0.47 vs 3.47 ± 0.48, 1.64 ± 0.45 vs 3.72 ± 0.46, 1.59 ± 0.56 vs 3.67 ± 0.59, 1.68 ± 0.36 vs 3.72 ± 0.38, P < 0.05 for all); these scores at 3 and 6 mo were significantly lower in the experiment group than in the control group (P < 0.05 for all). Conclusion: Comprehensive nursing intervention can improve self-care skills and mental and physical health in patients with rectal cancer after Miles operation. © 2014 Baishideng Publishing Group Co., Limited.
