Objective To explore the effect of Huashi Tongbi formula (HTF) in treating erectile dysfunction (ED) in rats and its therapeutic mechanism. Methods SD rats were divided into control group, sham surgery group, model control group, sildenafil group, and HTF low, medium, and high dose group, with 7 rats in each group. The sildenafil group was gavaged with sildenafil aqueous solution, the HTF group was gavaged with low, medium, and high doses of HTF aqueous solution, and the other three groups were gavaged with physiological saline for 6 weeks of intervention. ICP and MAP were measured, ICP/MAP was calculated, and serum TC, HDL-C, LDL-C, CRP, IL-6, and NO. Results Compared with the control group, the model control group showed a decrease in penile erection frequency, a decrease in ICP/MAP (P <0. 05), an increase in TC and LDL-C, a decrease in HDL-C (P <0.05), an increase in CRP, IL-6, and a decrease in NO (P <0.05). Compared with the model control group, the moderate dose group of HTF increased the number of penile erections ( P < 0. 05 ), while the various dose groups of HTF decreased LDL-C and increased HDL-C (P < 0.05), decreased CRP and IL-6, and increased NO (P< 0.05). Conclusion HTF improves dyslipidemia, inhibits inflammatory reactions, and increases serum NO levels for the treatment of ED in rats. [ABSTRACT FROM AUTHOR]

On the basis of the C60 high-strength fair-faced concrete mix ratio, the effects of the total amount of cementitious materials, slag powder content, silica fume content, water binder ratio and different particle size coarse aggregate content on the workability, mechanical properties and clean water effect of high-strength fair-faced concrete are studied by orthogonal test and image processing technology. The results are as follows, the influence degree on the slump of fair-faced concrete is as follows:total amount of cementitious materials>content of coarse aggregate with different particle sizes>content of slag powder>content of silica fume>water binder ratio, the degree of influence on the 28d compressive strength of fair-faced concrete is as follows:slag powder content>water binder ratio>total amount of cementitious materials>silica fume content>coarse aggregate content of different particle sizes, the influence degree on the effect of clean water is in the order of total amount of cementitious materials>silica fume content>slag powder content>water binder ratio>coarse aggregate content of different particle sizes.

On December 18, 2013, the US Federal Reserve announced to reduce the monthly assets purchase by 10 billion dollars. This shows that the US Federal Reserve officially launched the process to end its quantitative easing policy, and has raised great attention in the market. The tapering of US Federal Reserve's quantitative easing policy increases the uncertainty of global economic recovery, though its negative impacts on Chinese economy are limited. The ending of the US Federal Reserve's quantitative easing policy may prompt relevant economies to adopt similar monetary policies, and bring some pressure on the regulation of China's domestic monetary policies. The fluctuations of US dollars and US bond prices will bring about some impacts on RMB's exchange rate and China's foreign exchange reserves. The impact upon international financial order may also affect China. Facing the challenges brought about by the retreating of quantitative easing policy, China should continue with the adjustment of its economic restructuring and upgrading, implement a prudent monetary policy, strengthen cross-border supervision and control of funds, and keep a healthy, sustained growth in economical development.
