AIM:To Investigate the effects of transforming growth factorβ2(TGF-β2)and connective tissue growth factor(CTGF)on transdifferentiation of human lens epithelial cells(HLECs)cultured in vitro and synthesis of extracellular matrix(ECM).METHODS:HLECs were treated with TGF-β2(0,0.5,1.0,5,10μg/L)and CTGF(0,15,30,60,100μg/L)for different times(0,24,48,72h)in vitro and the expression ofα-smooth muscle actin(α-SMA),the main component of the extracellular matrix typeⅠcollagen(Col-1)and fibronectin(Fn)were measured by using real-time polymerase chain reaction(PCR)and ***:TGF-β2 and CTGF significantly increased expression ofα-SMA mRNA and protein(P<0.05,P<0.001),Fn mRNA and protein(P<0.001),Col-1 mRNA and protein(P<0.001).TGF-β2 could induce HLECs expression of CTGF mRNA and protein in dosedependent manner(P<0.05,P<0.001).TGF-β2 and CTGF could induce HLECs to expressα-SMA,Fn and Col-1 in time-dependent *** time of TGF-β2and CTGF induced HELCs expression ofα-SMA,Fn,Col-1 mRNA and protein was significant increase compared with control(P<0.05,P<0.001).CONCLUSION:TGF-β2 and CTGF could induce HLECs epithelial mesenchymal transition and ECM synthesis.

The successful launched Gaofen satellite no. 1 wide field-of-view （GF-1 WFV） camera is characterized by its high spatial resolution and may provide some potential for regional crop mapping. This study, taking the Bei＇an City, Northeast China as the study area, aims to investigate the potential of GF-1 WFV images for crop identification and explore how to fully use its spectral, textural and temporal information to improve classification accuracy. In doing so, an object-based and Random Forest （RF） algorithm was used for crop mapping. The results showed that classification based on an optimized single temporal GF-1 image can achieve an overall accuracy of about 83%, and the addition of textural features can im- prove the accuracy by 8.14%. Moreover, the multi-temporal GF-1 data can produce a classification map of crops with an overall accuracy of 93.08% and the introduction of textural variables into multi-temporal GF-1 data can only increase the accuracy by about 1%, which suggests the importance of temporal information of GF-1 for crop mapping in comparison with single temporal data. By comparing classification results of GF-1 data with different feature inputs, it is concluded that GF-1 WFV data in general can meet the mapping efficiency and accuracy requirements of regional crop. But given the unique spectral characteristics of the GF-1 WFV imagery, the use of textual and temporal information is needed to yield a satisfactory accuracy.

We described the preparation of copper oxide composite nanofibers doped with carbon nanotubes （CuO/C-NFs） or nickel oxide（CuO/NiO-NFs） by electrospinning for direct glucose determination. The interest in exploring practical CuO/C-NFs and CuO/NiO-NFs electrode materials for sensor application was fascinated by the possibility of promoting electron transfer for kinetically unfavorable glucose oxidation reactions at a lower overpo- tential and thus improving the selectivity of the electrode for glucose in electroanalysis. The morphologies of CuO/C-NFs and CuO/NiO-NFs were characterized by scanning electron microscopy（SEM） and X-ray powder diffraction（XRD）. The electrocatalytic performances of glucose were evaluated in detail by cyclic voltammetry（CV） and chronoamperometry. Facile charge transport, enhanced current response（at a lower overpotential of ＋0.35 V）, improved stability and selectivity, as well as excellent resistance towards electrode fouling were observed at CuO/ C-NFs electrode in direct glucose electroanalysis. These merits are attributed to the highly porous three-dimensional network film structure of CuO/C-NFs electrode materials and the potential synergic catalytic effect of CuO and carbon nanotubes in composite nanofibers. This study may provide a new insight into metal oxide-based composite nanofibers obtained via electrospinning for fabricating novel and high performance sensors and devices.

PARTICIPANTS： A total of 469 outpatients or inpatients with stroke were selected from the Department of Neurology, General Hospital of Fuxin Mining Industry Group from April 2002 to July 2005. All subjects met the diagnostic criteria of stroke established by the Fourth National Cerebrovascular Disease Academic Meeting in 1995 and were finally diagnosed with CT and MRI. Totally, 177 PSD patients were involved in the final analysis and provided the confirmed consent. There were 121 males and 56 females aged from 46 to 79 years. METHODS：（1） All the enrolled subjects were diagnosed for syndrome differentiation by senior TCM physicians within 1 week before discharge based on Diagnostics of Traditional Chinese Medicine, which was classified into 5 types, including sputum-stasis stagnation syndrome, qi stagnation and blood stasis, kidney-essence deficiency, deficiency of the spleen and stomach and phlegm-fire disturbing the heart. In addition, they were also assessed by neurologic deficit scale （NDS; 45 points in total; the higher the scores were, the severer the deficit was）, Fugl-Meyer assessment, （FMA; 100 points in total, including 66 points of upper limbs and 34 points of lower limbs; the higher the scores were, the stronger the motor function was）, m

Hepatocellular carcinoma(HCC) is a prevalent and highly malignant cancer throughout the *** treatment of this disease is impeded by the high rate of metastasis, recurrence, and chemoresistance. Recent studies have revealed the close relationship between the malignant phenotype of HCC and cancer stem cells(CSCs). Therefore, CSC-targeted therapy is considered a promising strategy to eradicate HCC. Traditional Chinese medicine(TCM) can be effective in preventing recurrence and metastasis of some advanced HCC. A growing amount of literature has discovered that extracts or compounds derived from TCM exert an anti-CSC effect. This review introduces some formulas and chemical compounds derived from TCMs that have been reported to inhibit CSCs of HCC;these TCM-related drugs may help to provide an alternative approach to help manage cancers, especially for HCC which has a great potential of metastasis, recurrence, and chemoresistance.

A better understanding of droplet formation and dripping behavior would be useful in the efficient removal of impurity elements and nonmetallic inclusions from liquid metals. In the present work, we developed a transparent experimental apparatus to study the mechanisms of droplet formation and the effects of filling ratio on droplet behavior during the electroslag remelting（ESR） process. A high-speed camera was used to clearly observe, at small time scales, the droplet formation and dripping phenomenon at the slag/metal interface during a stable ESR process. The results illustrate that a two-stage process for droplet formation and dripping occurs during the ESR process and that the droplet diameter exhibits a parabolic distribution with increasing filling ratio because of the different shape and thermal state of the electrode tip. This work also confirms that a relatively large filling ratio reduces electricity consumption and improves ingot quality.
