Background We compared the validity （evaluated by sensitivity and specificity）, reliability （evaluated by reproducibility） and yield （evaluated by predictive value, examining complexity and cost） of individual and combined tests for bladder tumour antigen stat （BTAstat）, nuclear matrix protein 22 （NMP22）, hyaluronic acid （HA）, survivin, CD44v6, vascular endothelial growth factor （VEGF）, and voided urine cytology （VUC） in detecting bladder cancer. And at the same time we evaluated the clinical value of these seven detecting methods in the diagnosis of bladder cancer. Methods The six markers and VUC were detected in the urine of cancer group （151 patients with bladder cancer） and two control groups （50 patients with benign urological diseases and 50 healthy controls）. The sensitivity, specificity, predictive value, reproducibility, examining complexity and checking cost of each marker and combined markers were calculated. Results There was a significant difference between bladder cancer group and the two control groups. The sensitivity, specificity and positive predictive value were as follows： VUC （36.4%, 100.0%, 100%）, BTAstat （76.8%, 87.0%, 89.9%）, NMP22 （77.5%, 81.0%, 86.0%）, HA （82.8%, 83.0%, 88.0%）, survivin （70.2%, 85.0%, 87.6%）, CD44v6 （50.3%, 79.0%, 78.4%）, and VEGF （68.2%, 93.0%, 93.6%）. The highest sensitivities were 91.4% for NMP22＋BTAstat and HA＋NMP22, whereas the combined marker with the lowest sensitivity （62.3%） was VUC＋CD44v6. The highest specificity was 93.0% for the combined use of VUC＋VEGF and HA＋CD44v6 had the lowest specificity （73.0%）. The most convenient examining method was the detection for BTAstat, the lowest cost was the detection for HA, and the best reproducibility were the detection for BTAstat and VUC. Conclusions All the markers have obvious clinical value in diagnosis of bladder cancer. The use of BTAstat＋HA or NMP22＋BTAstat are better examining methods in terms of validity, reliability, and yield.

We use transient terahertz photoconductivity measurements to demonstrate that upon optical excitation of CH_(3)NH_(3)PbI_(3)perovskite,the hole transfer from CH_(3)NH_(3)PbI_(3)into the organic hole-transporting material(HTM)Spiro-OMe TAD occurs on a sub-picosecond ***-order recombination is the dominant decay pathway at higher photo-excitation fluences as observed in neat CH_(3)NH_(3)PbI_(3)*** contrast,under similar experimental conditions,second-order recombination weakly contributes the relatively slow recombination between the electrons in the perovskite and the injected holes in HTM,as a loss mechanism at the CH_(3)NH_(3)PbI_(3)/Spiro-OMe TAD *** results offer insights into the intrinsic photophysics of CH_(3)NH_(3)PbI_(3)-based perovskites with direct implications for photovoltaic devices and optoelectronic applications.

The MgO/NaY catalysts prepared by impregnation method were used for the conversion of glucose to fructose in water medium. The effects of MgO loading, reaction temperature, glucose concentration and reaction time on the catalytic performance for the reaction were studied. The activity testing results indicated that fructose could be generated effectively by controlling the components of the catalyst and reaction conditions. The maximal fructose yield of 33.8% with the selectivity of 67.3% was achieved over the 10%MgO/NaY catalyst at 100 ℃ for 2 h. Moreover, the catalysts were characterized by XRD, BET, and CO2-TPD techniques. The structural property of NaY with higher surface area facilitated glucose conversion, and the modulated basicity of the catalyst with MgO addition contributed to the formation of fructose in the tautornerization of aldose to ketose.
