Melt pre-shear induced crystallization of polymer blends holds great significance in industrial processing and product *** this work,two typical PB/PP blends(50/50,90/10),possessing commercial value and academic hotspot,were employed to investigate the effect of melt pre-shear on the crystallization of isotactic poly(1-butene)(PB)and polypropylene(PP)by applying shearing slightly above the melting temperature of PP with subsequent non-isothermal crystallization to simulate actual processing *** was discovered that in PB/PP(90/10)blend,in situ melt pre-shear generated oriented PP precursors induced the formation of PP-FIC(Flow-induced crystallization)which acted as row crystal nucleus significantly promoting PB crystallization into spherulite with higher melting temperatures(T_(m)),crystallinity(X_(c)),and thicker lamellar thickness(d_(c)).While in PB/PP(50/50)blend,the melt pre-shear generated PP-shish precursors induced the formation of PP shish-kebab that exerted a confining effect on the crystal growth of PB,resulting in truncated spherulite formation with higher T_(m) and thicker d_(c) but lower X_(c).This research provides insight into the mechanism underlying oriented crystal structure formation,crystal properties,and phase morphology of PB/PP blends under melt pre-shear fields,which have significant theoretical and practical implications for their industrial processing and preparation of high-performance products.

Flavonoids from Huangqin（dried roots of Scutellaria baicalensis Georgi） have anti-inflammatory effects, and are considered useful for treatment of spinal cord injury. To verify this hypothesis, the T9-10 spinal cord segments of rats were damaged using Allen＇s method to establish a rat spinal cord injury model. Before model establishment, Huangqin flavonoid extraction（12.5 g/kg） was administered intragastrically for 1 week until 28 days after model establishment. Methylprednisolone（30 mg/kg） was injected into the tail vein at 30 minutes after model establishment as a positive control. Basso, Beattie, and Bresnahan locomotor scale scores were used to assess hind limb motor function. Hematoxylin-eosin staining was used to detect pathological changes in the injured spinal cord. Immunofluorescence and western blot assays were performed to measure immunoreactivity and expression levels of brain-derived neurotrophic factor, neuronal marker neurofilament protein, microglial marker CD11 b and astrocyte marker glial fibrillary acidic protein in the injured spinal cord. Huangqin flavonoid extraction markedly reduced spinal cord hematoma, inflammatory cell infiltration and cavities and scars, and increased the Basso, Beattie, and Bresnahan locomotor scale scores; these effects were identical to those of methylprednisolone. Huangqin flavonoid extraction also increased immunoreactivity and expression levels of brain-derived neurotrophic factor and neurofilament protein, and reduced immunoreactivity and expression levels of CD11 b and glial fibrillary acidic protein, in the injured spinal cord. Overall, these data suggest that Huangqin flavonoid extraction can promote recovery of spinal cord injury by inducing brain-derived neurotrophic factor and neurofilament protein expression, reducing microglia activation and regulating reactive astrocytes.

Microarray data are often extremely asymmetric in dimensionality, such as thousands or even tens of thousands of genes but only a few hundreds of samples or less. Such extreme asymmetry between the dimensionality of genes and samples can lead to inaccurate diagnosis of disease in clinic. Therefore, it has been shown that selecting a small set of marker genes can lead to improved classification accuracy. In this paper, a simple modified ant colony optimization （ACO） algorithm is proposed to select tumorelated marker genes, and support vector machine （SVM） is used as classifier to evaluate the performance of the extracted gene subset. Experimental results on several benchmark tumor microarray datasets showed that the proposed approach produces better recognition with fewer marker genes than many other methods. It has been demonstrated that the modified ACO is a useful tool for selecting marker genes and mining high dimension data

AIM： To investigate the expression of Neurensin-2 （NRSN2） in hepatocellular carcinoma （HCC） and its prognostic values in predicting survival. METHODS： The expression and prognostic significance of NRSN2 in HCC was examined by performing immunohistochemical analysis using a total of 110 HCC clinical tissue samples, and Western blotting analysis to further confirm the result. RESULTS： Decreased NRSN2 expression was shown in 70.9% cases. Loss of NRSN2 expression in HCC was significantly related to tumor size （P = 0.006）. Larger tumor size was related to negative expression of NRSN2. Patients showing negative NRSN2 expression had a significantly shorter overall survival than those with positive expression （P = 0.008）. Multivariate Cox regression analysis indicated that NRSN2 expression level was an independent factor of survival （P = 0.013）. Western blotting analysis further confirmed decreased expression of NRSN2 in tumor tissues compared with non-tumorous tissues. CONCLUSION： Our study indicated that NRSIV2 could be a tumor suppressor gene for HCC and a candidate biomarker for long-term survival in HCC.
