Background:Disease-modifying therapy is the standard treatment for patients with multiple sclerosis (MS)in *** primary objective of the current analysis was to assess the efficacy and safety of two teriflunomide doses (7mg and 14mg)in the subgroup of Chinese patients with relapsing MS included in the TOWER study. Methods:TOWER was a multicenter,multinational,randomized, double-blind,parallel-group (three groups),placebo-controlled *** subgroup analysis includes 148 Chinese patients randomized to receive either teriflunomide 7mg (n =51), teriflunomide 14mg (n=43),or placebo (n=54). Results:Of the 148patients in the intent-to-treat population, adjusted annualized-relapse rates were 0.63(95% confidence interval [CI]:0.44,0.92)in the placebo group,0.48(95%CI:0.33, 0.70)in the teriflunomide 7mg group,and 0.18(95%CI:0.09,0.36)in the terifltmomide 14mg group;this corresponded to a significant relative risk reduction in the teriflunomide 14mg group versus placebo (-71.2%,P =0.0012).Terifiunomide 14mg also tended to reduce 12-week confirmed disability worsening by 68.1% compared with placebo (hazard ratio:0.319,P =0.1194).There were no differences across all treatment groups in the proportion of patients with treatment-emergent adverse events (TEAEs;72.2% in the placebo group,74.5%in the teriflunomide 7mg group,and 69.8% in the teriflunomide 14mg group);corresponding proportions for serious adverse events were 11.1%,3.9%,and 11.6%,*** most frequently reported TEAEs with teriflunomide versus placebo were neutropenia,increased alanine aminotransferase,and hair thinning. Conclusions:Teriflunomide was as effective and safe in the Chinese subpopulation as it was in the overall population of patients in the TOWER *** has the potential to meet unmet medical needs for MS patients in China.

为使TiO2能够在可见光下发挥其于紫外激发的高光催化活性降解室内甲醛,采用水热处理法将TiO2与掺杂稀土离子Er3+的上转换发光剂Er3+∶YAlO3结合,制备具有可见光响应的Er3+∶YAlO3/TiO2光催化剂,并对其进行了表征分析。结果表明,TiO2以锐钛矿为主,且Er3+∶YAlO3可有效地将可见光上转换至可激发TiO2的紫外光。在箱式反应器中进行光催化降解气态甲醛,研究了甲醛初始浓度与催化剂用量对甲醛降解效率的影响。结果表明,该光催化反应的假一级反应速率常数(kapp)与甲醛初始浓度成正相关,而随催化剂用量的增加先升高后降低。当甲醛初始浓度为0.058 mg/m3、催化剂用量为0.122 4 g/L时,kapp最大为3.65×10-3min-1。该反应符合Langmuir-Hinshelwood模型,反应速率常数为5×10-8mg/(L·min)。
