OBJECTIVE: To assess the efficacy of Huangshukuihua(Flos Abelmoschi Manihot) on diabetic nephropathy(DN).METHODS: Articles were retrieved from Pub Med,EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure Database, Chinese Evidence-Based Medicine Database, and Wanfang Database. Two reviewers independently reviewed the article. Only randomized controlled trials were included and 27 were identified involving 2239 patients(1143 in the treatment group and 1096 in the control group).RESULTS: Huangshukuihua(Flos Abelmoschi Manihot) had a significant effect on renal function by improving blood urea nitrogen and serum creatinine,reducing urine protein(24-h urine protein, and urinary albumin excretion rate), and improving serum albumin level, compared with the control ***: Our findings suggest that, although the bioactive ingredients and mechanism underlying renal protection are unknown, the role of Huangshukuihua(Flos Abelmoschi Manihot) in the treatment of DN deserves further investigation.

The scale and characteristics of rock mass are important indexes of the rock mass structural plane classification. This paper firstly analyzes the spatial distribution characteristics, the structural plane types （original structural plane, tectonic structural plane and hypergenic structural plane） and the associated features of the Emeishan basalts and then studies the classification schemes of the built hydropower structure planes of different rock areas （the east district, the central district and the west district） in the Emeishan basalt distribution area, Southwest China. Based on the analysis and comparison of the scale and the engineering geological characteristics of the typical structure planes in the basalt hydroelectric Stations, the types of structural planes are used in the first order classification. The secondary order classification is made by considering the impact factors of rock mass quality, e.g., the state of the structural planes, infilling, joint opening, extending length, the grade of weathering and strength. The engineering geological classification for Emeishan basalt is proposed. Because there are no evidences of a large structure presenting in study area, the first-order （Ⅰ） controlling structural planes do not appear in the classification, there only appear Ⅱ, Ⅲ, Ⅳ and Ⅴ grade structural planes influencing the rock-mass quality. According to the different rock-block types in bedding fault zone, the second-grade （Ⅱ） structural planes consisted of bedding fault zone is further classified into Ⅱ1, Ⅱ2 and Ⅱ3. The third-grade （Ⅲ） structural planes constructed by intraformational faulted zones are not subdivided. According to the different characteristics of intrusion, alteration and weathering unloading structural planes, the Ⅳ grade structure plane is divided into Ⅳ1, Ⅳ2 and Ⅳ3. According to the development characteristics of joints and fractures, the V grade structure plane is divided into fracture Ⅴ1 and columnar joint Ⅴ2. In all, the struc

A novel electrochemical approach for detection of saccharides via indicator displacement assay was presented. In this system, 2-fluorophenylboronic acid and dopamine （DA） were performed as probe set. The electrochemical properties of DA and the binding to 2-fluorophenylboronic acid in phosphate buffer at different pH values were investigated by cyclic voltammetry. After addition of fructose to the solution, a competition for the binding 2-fluorophenylboronic acid occurred that led to the release of the DA. The regenerate oxidation current of DA increased with increasing fructose concentration. Under optimized experimental conditions, the peak current was linearly related to fructose concentration in the range of 0.3-5.0 mmol[L with a detection limit of 0.1 mmolJL In addition, the interaction between 2- fluorophenylboronic acid and other cis-diol compounds such as glucose, galactose and mannose was investigated.

FeX3（X = Cl, Br） were found to be very effective reagents and powerful catalysts for regioselective ring openings of a variety of N-tosylaziridines with them to afford the corresponding b-haloamines in good to excellent yields with high regioselectivity under mild conditions. At the same time, 13 new compounds were obtained firstly. Moreover, the b-bromoamine prepared could be transferred into b-nitroamine with NaNO2 in moderate yield.

By adopting the solid modeling software SoldEdge and the enmeshment software SRIFCast as the pre-processingplatform, a Ni based alloy turbine blade was three-dimensionally modeled and automatically enmeshed. A softwarecode for numerical simulation of fluid flow and heat transfer was developed. The Xue criterion and Niyama criterionwere used to predict the position of the shrinkage defects occurring in the solidification processes of the turbine *** results showed that both Xue and Niyama criteria could precisely predict the shrinkage defects in the Ni basedalloy turbine blade. This indicates that numerical simulation is a significant tool in improving casting quality.
