The kinetics of the decomposition of acid dissolved titanium slag with a sodium hydroxide system under atmospheric pressure was studied. The effect of reaction temperature, particle size and NaOH-to-slag mass ratio on titanium extraction was investigated. The results show that temperature and particle size have significant influence on titanium extraction. The experimental data of titanium extraction show that the shrinking core model with chemical reaction controlled process is most applicable for the decomposition of slag, with an apparent activation energy of 62.4 ***^-1. Approximately 85 wt.%-90 wt.% of the titanium can be extracted from the slag under the optimal conditions. In addition, the purity of titanium dioxide obtained in the product is up to 98.5 wt.%.

目的预测2030年山东省结直肠癌(colorectal cancer,CRC)的死亡负担,评估控制危险因素对减轻CRC死亡负担的效果。方法基于死亡风险与危险因素的相关性和比较风险评估理论,利用山东省危险因素监测数据和CRC死亡数据,结合WHO危险因素控制目标,设定不同的危险因素控制场景,采用比例变化模型估计2030年不同场景下CRC死亡情况。结果若危险因素暴露按自然趋势发展,2030年山东省>20岁人群CRC的死亡数和死亡率将比2013年分别增加47.68%和35.51%,标化死亡率和过早死亡概率将分别降低14.48%和10.10%。饮酒或BMI控制达标场景下,2030年山东省>20岁人群过早死亡概率将比2013年减少12.11%和11.02%。所有危险因素控制达标场景下,2030年山东省将避免413.24人死亡,过早死亡概率将降低13.14%。结论自然趋势下,2030年山东省>20岁人群CRC死亡数和死亡率将比2013年高,标化死亡率与过早死亡概率将下降。若所有危险因素控制达标,可降低CRC的负担,提示应加强控制饮酒和BMI管理等措施,以降低山东省CRC的死亡负担。

Chronic exposure to drugs of abuse will give rise to persistent structural and functional changes in the central nervous system. These phenomena are usually referred as ′drug-induced neuroplasticity′ and depend on changes in gene expression. The cAMP response element binding protein(CREB),as a downstream molecule in mediating the actions of cAMP is an important transcriptional factor in establishing and maintaining addiction to drugs of abuse. Application of a PDE4 inhibitor attenuates the rewarding properties of cocaine and morphine. Given the fact that PDE10A is specifically located in striatum,an important structure involved in the reward circuit,we thus investigated the PDE10A inhibitormodulated the behavioral reinforcement exerted by morphine. The results show that MP-10 2.5 mg·kg^(-1),administered subcutaneously,significantly inhibited the acquisition of morphine-induced CPP. Moreover,MP-10 did not alter the expression of morphine-induced CPP,but did accelerate the extinction of morphine-induced CPP. Additionally,chronic treatment with MP-10 2.5 mg·kg^(-1)decreased expression of phosphorylated CREB(pC REB) in dorsomedial striatum,in shell of NAc,and in anterior cingulate cortex(ACC) as well as decreased expression of ΔFos B in the shell of NAc and ACC. These data indicate that PDE10A inhibition may have a potential therapeutic effect on addiction. Since the MP-10 has relative short metabolic Stability,we also developed a few novel potent new PDE10A selective inhibitor with improved stability and brain exposure. The new compound exhibited promising potential in schizophrenia and addiction treatment.

A method was proposed for removing zirconium （Zr） from hydrous titanium dioxide （HTD） by the NaF solution. The effects of main parameters, i.e. pH values, NaF dosage, temperature and retention time, on the removal of zirconium were stud- ied. The optimal conditions were found as the following： pH value, 〈5.5; molar ratio of NaF to TiQ, 0.6; retention time, 80 min and temperature, 80℃. The removal rate of Zr under the optimized conditions was above 87.7%. The adsorption energy of the preferential absorption of hydrofluoric acid for Zr（OH）2SOt（OH2） on the （001） crystal surface of HTD was determined by theo- retical calculation. The possible mechanism of the removal process was also discussed.

Dear Editor, Protein degradation is an essential process for protein dynamics and the development of living organisms, and defective protein degradation can lead to abnormalities in protein accumulation and cell functions. In addition to the conserved proteasome- dependent pathway in both mammals and plants, the lytic vacuole-dependent pathway is crucial for protein degradation in plants （Cai et al., 2014）.

As the process parameters of pilger cold-rolled seamless steel tubes are basically based on experience leading to the generation of defects, 304 stainless steel was chosen and the important process parameters including the feed, rotation angle and Q value (the ratio of the length of the deformation section to that of the finishing section) were selected to analyze the effect of different process parameters on the tube forming process and rules. The results show that during the cold rolling process, the rolling force, the equivalent stress of the tube, the residual stress and the springback of the external diameter increased with the increase in the feed rate and the rotation angle and the decrease in Q value. Increasing the feed quantity and decreasing Q value will lead to the decrement in the roundness of the pipe. After comprehensive evaluation of the advantages and disadvantages, a set of optimal parameters are selected to carry out the experiment. The residual stress and the outer diameter of the finished products were measured. The results of the measurement and the numerical simulation results are within reasonable range, and the accuracy of the numerical simulations and the influence of the process parameters on the pilger cold rolling are further verified.
