Rainfall-runoff modeling is essential for addressing a wide range of issues in urban drainage system design and operation in both scientific research and engineering ***,it has become increasingly attractive to use the smoothed particle hydrodynamics(SPH)method to model rainfall-runoff because of its inherent features such as mesh-free and automatic adaptiveness for wet-dry ***,one of its inadequacies is the lack of an infiltration effect within rainfall-runoff ***,we propose a new methodology that innovatively integrates the infiltration effect into the shallow water equation(SWE)system with the SPH method(SPH-SWE)to represent a more complete rainfall-runoff *** the proposed method,the mass-varied SPH-SWE(MVSPH-SWE)method is enhanced by integrating the infiltration model.A naked area treatment(NAT)method is subsequently proposed to improve the modeling efficiency and *** obtained numerical results are validated using experimental data from the *** results demonstrate that the proposed method is accurate and *** achievements and findings of this study are expected to improve and extend the use of existing hydrological process models.

The differential evolution （DE） algorithm has been received increasing attention in terms of optimizing the design for the water distribution systems （WDSs）. This paper aims to carry out a comprehensive performarice comparison between the new emerged DE algorithm and the most popular algorithm-the genetic algorithm （GA）. A total of six benchmark WDS case studies were used with the number of decision variables ranging from 8 to 454. A preliminary sensitivity analysis was performed to select the most effective parameter values for both algorithms to enable the fair comparison. It is observed from the results that the DE algorithm consistently outperforms the GA in terms of both efficiency and the solution quality for each case study. Additionally, the DE algorithm was also compared with the previously published optimization algorithms based on the results for those six case studies, indicating that the DE exhibits comparable performance with other algorithms. It can be concluded that the DE is a newly promising optimization algorithm in the design of WDSs.

The particles of ferric aluminum magnesium hydrotalcite-like compounds (Fe-Al-Mg_HTlc) were synthesized by co-precipitation method. It was found that when n(Fe)/n(Al+Mg+Fe)0.30, Al(OH)3 will emerge; when the molar ratio of Fe/(Fe+Al+Mg) >0.30, the amorphous composition will appear. Hence Fe3+ and Al3+ have no concentration superposition effect on the crystal structure of the samples.

The essential oils of the flower-buds, leaves and stems of Filipendula palmata（ Pall. ） Maxim. were analyzed by GC and GC-MS. Thirty-three, forty-seven and forty-seven compounds in the flower-buds, leaves and stems were identified, respectively. Methyl salicylate exists in a great amount which is up to 70. 10% in the flower-buds. Its amount is also high in other two parts. The data obtained show that it may be one of the main natural mosquito-expelling and pain-alleviating components in the three parts. The flower-buds are the main active part with the mosquito-expelling function.

Objective Cytotoxin-associated protein （CagA） of H. pylori has been confirmed to be closely associated with gastric inflammation and tumorigenesis, but the mechanism behind it is little understood. In this study, we try to determine roles of CagA＋ strain in activating PI3K/Akt1 signaling pathway, and affecting expression of p21WAF1/CIP1 and p27KIP1, and also in releasing IL-8 in host cells. Methods Akt1 phosphorylation and IL-8 levels of CagA＋ and CagAˉ strain infected AGS cells were detected by EliSAs. Two quantitative RT-PCRs were established to measure p21WAF1/CIP1 and p27KIP1 mRNA levels in the CagA＋ and CagAˉ strain infected cells. LY294002, an inhibitor of PI3K/Akt pathway, was used to define effect of the pathway in IL-8 release. Results CagA＋ strain could induce an obvious elevation of Akt1 phosphorylation in the infected AGS cells while CagAˉ strain failed to do so. The CagA＋ H. pylori strain infected AGS cells showed significant drops both in p21WAF1/CIP1 and p27KIP1 mRNA levels, whereas the CagAˉ H. pylori strain caused a remarkable increase in p21WAF1/CIP1 mRNA without affecting p27KIP1 gene transcription in the AGS cells. Both the CagA＋ and CagAˉ H. pylori strains enabled AGS cells to produce close elevated levels of IL-8, and the LY294002 block resulted in unexpected elevations of IL-8 levels. Conclusion CagA can activate PI3K/Akt1 pathway that plays an inhibitory role in IL-8 release in H. pylori infected AGS cells. Activation of PI3K/Akt1 pathway and subsequent negative regulation of p21^WAF1/CIP1 and p27^KIP1 expression might be involved in CagA-associated carcinogenesis.

A homogeneous catalyst [Cp＊Rh（NH3）（H2O）2]-（3＋） has been found for the clean conversion of methanol and water to hydrogen and carbon dioxide. The simple and easily available reaction steps can circumvent the formation of CO, therefore, making it possible to avoid inactivating catalysts and contaminating the hydrogen fuel. Different from conventional reforming method for hydrogen production, no additional alkaline or organic substances are required in this method. Valuable hydrogen can be obtained under ambient pressure at 70 C, corresponding TOF is 83.2 h 1. This is an unprecedented success in reforming methanol to hydrogen. Effects of reaction conditions, such as reaction temperature, initial methanol concentration and the initial p H value of buffer solution on the hydrogen evolution are all systematically investigated. In a certain range, higher reaction temperature will accelerate reaction rate. The slightly acidic condition is conducive to rapid hydrogen production. These findings are of great significance to the present establishment of the carbon-neutral methanol economy.

Dear Editor, 46,XY disorder of sex development （DSD） is characterized by a female phenotype in an individual with a normal 46,XY karyotype.1 The clinical phenotTpe of 46,XY DSD is characterized by bilateral undescended testes and a normal female appearance, including breasts, female external genitalia, and other secondary sex characteristics, but the absence of a uterus or ovaries.2 Development of the male external genitalia in the fetal period depends on the biosynthesis of testosterone （T）, the conversion ofT into dihydrotestosterone （DHT） by steroid 5α-reductase type 2 （SRD5A2）, and the response of functionally active androgen receptors in genital tissues） The disruption of any of these stages will block the differentiation of internal and external genitalia and cause 46,XY DSD.
