Electrostatic interaction conductive hybrids were prepared in water/ethanol solution by the sol-gel process from inorganic sol containing carboxyl group and water-borne conductive polyaniline （cPANI）. The electrostatic interaction hybrids film displayed 1-2 orders of magnitude higher electrical conductivity in comparison with common hybrids film, showing remarkable conductivity stability against water soaking. Most strikingly, it displayed ideal electrochemical activity even in a solution with pH = 14, which enlarged the conducting polyaniline application window to strong alkaline media.

A muitisensor image fusion algorithm is described using 2-dimensional nonseparable wavelet frame （NWF） transform. The source muitisensor images are first decomposed by the NWF transform. Then, the NWF transform coefficients of the source images are combined into the composite NWF transform coefficients. Inverse NWF transform is performed on the composite NWF transform coefficients in order to obtain the intermediate fused image. Finally, intensity adjustment is applied to the intermediate fused image in order to maintain the dynamic intensity range. Experiment resuits using real data show that the proposed algorithm works well in muitisensor image fusion.

Characterized by complex lithology and strong heterogeneity, volcanic reservoirs in China developed three reservoir space types： primary pores, secondary pores and fractures. The formation of reservoir space went through the cooling and solidification stage （including blast fragmentation, crystallization differentiation and solidification） and the epidiagenesis stage （including metasomatism, filling, weathering and leaching, formation fluid dissolution and tectonism）. Primary pores were formed at the solidification stage, which laid the foundation for the development and transformation of effective reservoirs. Secondary pores were formed at the epidiagenesis stage, with key factors as weathering and leaching, formation fluid dissolution and tectonism. In China, Mesozoic-Cenozoic volcanic rocks developed in the Songliao Basin and Bohai Bay Basin in the east and Late Paleozoic volcanic rocks developed in the Junggar Basin, Santanghu Basin and Ta- rim Basin in the west. There are primary volcanic reser- voirs and secondary volcanic reservoirs in these volcanic rocks, which have good accumulation conditions and great exploration potential.

Background Autologous peripheral stem cell transplantation was first reported in 2007 to treat type 1 diabetes mellitus （DM） and achieved encouraging effect, but whether similar outcome can be achieved in type 2 DM is not well demonstrated. The objective of this study was to determine the effect of combination of autologous bone marrow stem cell transplantation （BMT） and hyperbaric oxygen treatment on type 2 DM. Methods The study involved 31 patients with type 2 DM （aged 33 to 62 years） from January 2009 to January 2011 in the Central Hospital of Wuhan, China. Clinical variables （body mass index, duration of DM, insulin requirement, oral hypoglycemic drugs, time free from insulin, time free from oral drugs） and laboratory variables （hemoglobin Alc （HbAlc）） mononuclear cells infused, and C-peptide in four time points） were assessed. Purified bone marrow stem cells were infused into major pancreatic arteries. Follow-up was performed at the 30, 90, 180, 360, 540 and 720 days （mean 321 days） after BMT. Results Mean HbAlc values showed a significant reduction during follow-up in all patients after BMT. It decreased by more than 1.5% （from 8.7% to 7.1%） as quickly as at 30 days after BMT. Afterwards mean HbAlc fluctuated between plus or minus 0.5% until 24 months rather than declined continuously. At 90 days after the combined therapy C-peptide increased significahtly compared with baseline （P 〈0.0001）. But in other time points C-peptide was similar with baseline data （P〉0.3）. All patients had insulin and/or oral hypoglycemic drugs reduced to different levels. The dose of insulin of 7 patients （7/26, 27%） reduced for a period of time after BMT. Conclusions Combined therapy of intrapancreatic BMT and hyperbaric oxygen treatment can improve glucose control and reduce the dose of insulin and/or oral hypoglycemic drugs in type 2 DM patients, but it only improve pancreatic 13-cell function transiently. Further randomized controlled clinical trials involved more patients will b

采用脉冲直流反应磁控溅射镀膜方法在透明导电玻璃FTO（SnO2：F）上制备厚度分别为50、100、150、200、250和300 nm的WO3薄膜。分析了薄膜着色前后晶体结构和表面形貌的变化,对薄膜的循环伏安特性和光学性能进行测试。结果表明：不同厚度氧化钨薄膜均为结晶态,具有单斜晶系结构;随着薄膜厚度增加,薄膜结晶程度逐渐增加;薄膜着色/褪色循环中,不同厚度的WO3薄膜均发生单斜晶系WO2.92与立方晶系WO3的可逆转变,产生晶格应变,并且随厚度增加,薄膜晶格应变先减小后增大,薄膜厚度为250 nm时,变色前后晶格应变最小,厚度增加至300 nm薄膜时,着色产生应变明显增大。在相同驱动电压下,随薄膜厚度增加,光学调制幅度（550 nm）、着色效率先增大后减小,厚度为250 nm时获得最大调制幅度76.01%和着色效率21.04 cm2/C;当厚度进一步增加至300 nm时,薄膜褪色态透过率降低到49.30%后无法继续褪色,着色效率也开始下降。使用XPS分析了薄膜着、褪色状态下W元素的化学态,发现300 nm薄膜褪色后一部分W5＋无法转变成W6＋,导致薄膜仍为蓝色。

AIlergic diseases of the airway, which include seasonal rhinitis, chronic perennial rhinitis and asthma, are recognized as inflammatory disorders of the airway mucosa, but differ in the location of the inflammatory reaction and clinical manifestations of the disease. Asthma and allergic rhinitis frequently coexist in the same patient and are thought to share common predisposing genetic factors which interact with the environmental influences. Both diseases have increased in prevalence over recent decades particularly in westernized countries. This increase has been largely attributed to environmental factors such as exposure to aerial pollutants and early life events, including the degree of exposure to infectious agents which might affect IgE production, since there has been insufficient time for a significant change in the gene pool.

Background Numerous Asian cases of avian influenza virus infection, especially the highly pathogenic strain H5N1, in humans have raised the concern that another influenza pandemic is close. However, there are no effective therapeutic drugs or preventative vaccines available. Hemagglutinin is the membrane glycoprotein of avian influenza virus responsible for receptor binding to human cells and the main immunogenic protein that elicits a strong immune response. Although this protein is of great importance to the study of pathogenesis and vaccine development, its expression and purification are difficult due to high levels of glycosylation. Methods In this study, we expressed codon-optimized, full-length hemagglutinin 5 （H5） protein fused with a human IgG Fc tag （H5-Fc） in HEK293 cells. To enhance secretion of this protein, we also deleted the transmembrane domain and the intracellular domain of the H5 protein （H5ATM-Fc）. Purified proteins were obtained using a protein A column. Results ELISA revealed that the yield of soluble H5ATM-Fc protein in the supernatant was about 20 mg/L. Western blotting and fluorescence activated cell sorter （FACS） indicated that the purified H5 protein was correctly folded and biologically active. Conclusion Purification of H5 proteins from mammalian cells could be used for large-scale production of recombinant H5 protein for basic scientific research or the development of vaccines.

In EUV and X- ray regions, multilayer mirrors are the essential and necessary optics elements. The good prospects of the EUV and X- rays for next generation lithography system, microscopy in the “water windows”, astro- nomical telescope, spectroscopy, plasma diagnostics, and X- ray laser have impelled the development of multilayer optics. The paper introduces the recent results of the multilayer optics elements in Tongji University, including beam splitters, broadband/angular polarizers, supermirrors and high- reflectance mirrors. The product of reflectivity and transmissivity is above 4% for the Mo/Si multilayer beam splitter. Over the 15￣17 nm wavelength range, the s- re- flectivity of the non- periodic Mo/Si broadband multilayer polarizers is reasonably constant, as high as 36.6%, and the degree of polarization is more than 97.8%. At the fixed energy of 8 keV (Cu Kαline), the W/Si supermirror has the reflectivity of above 30% in the angle range of 0.4°￣0.85°, and a W/B4C supermirror has the reflectivity of about 20% in the angle range of 0.9°￣1.2°, and the reflectivity of W/C supermirror working in the grazing incident angle range of 0.9°￣1.2°is about 20%. The experimental results of some high- reflectance mirrors in our lab are also pre- sented, such as Mo/Si, Mo/Y, Cr/C, La/B4C, Si/C and Si/SiC. The reflectivity of Mo/Si multilayer is as high as 61.1% at wavelength of 13.4 nm.
