This study explored the synergistic interaction of sewage sludge(SS)and distillation residue(DR)during co-pyrolysis for the optimized treatment of sewage sludge in cement kiln systems,utilizing thermogravimetric analysis(TGA)and thermogravimetric analysis with mass spectrometry(TGA-MS).The results reveal the coexisting synergistic and antagonistic effects in the co-pyrolysis of SS/*** synergistic effect arises from hydrogen free radicals in SS and catalytic components in ash fractions,while the antagonistic effect is mainly due to the melting of DR on the surface of SS particles during pyrolysis and the reaction of SS ash with alkali metals to form inert ***/DR co-pyrolysis reduces the yielding of coke and gas while increasing tar *** study will promote the reduction,recycling,and harmless treatment of hazardous solid waste.

基于生态系统服务理论,乡村振兴的实质是增长乡村景观生态系统服务价值(ESV)。以安徽省长丰县为例,利用2000—2020年3期土地利用数据,采用渔网法与景观类型动态度、单位面积价值当量法、地理探测器模型等方法结合,分析景观结构变化特征、ESV特征及其空间分布和ESV空间分异驱动力,对长丰县景观ESV提升提供建议。结果显示,近20年,长丰县以耕地景观为主,占比均在0.8以上,水体、林地景观大幅增长,增长量分别为3.669×10^(3)、1.258×10^(3) hm^(2)。总ESV呈增加趋势,从1.098×10^(9)元增长至1.756×10^(9)元,主要是退耕还林、还湖对生态系统服务功能提升具有积极作用;ESV高的区域分布与水体、湿地和林地分布一致;各景观类型敏感性系数均小于1,评估结果可信;归一化植被指数(NDVI)的驱动力度最高,为0.349,是长丰县ESV空间分异的主要驱动因子,且多因子交互作用的影响比单因子更为显著。

Objective： The aim of this study was to evaluate the anti-tumor activity and safety of Gemcitabine （GEM） combined with Vinorelbine （NVB） in patients with advanced TNABC after chemotherapy. Methods： Thirty-seven patients with immunohistochemical proved TNABC were enrolled. The patients received 21-day cycles of NVB 25mg/m^2 i.v. with GEM 1000 mg/m^2 i.v. on days 1 and 8. Results： A total of 136 cycles were given to 37 patients（median 4 cycles, ranged 2-6 cycles）. The treatment response was evaluable in all patients. Of the 37 patients, 1 received complete remission （CR）, 8 received partial remission （PR）, 20 had stable disease （SD）, 9 had progressive disease （PD）. Overall objective response （CR＋ PR） were 24.3 %. The median time to progress （TTP） was 6 months （95% CI, 4-6 months）. The median overall survival was 24 months （95% CI, 11-37 months）. The median 1-year survival rate was （66.24±8.43）%. The median 3-year survival rate was （28.77±11.96）%. The major adverse events were grade Ⅰ-Ⅱ myelosuppression, peripheral neurologic toxicities, nausea and vomiting. Some patients had rash and hepatic dysfunction. A total of 40% of patients experienced flu-like symptoms. Alopecia and diarrhea were rare. Conclusion： The combination of GEM and NVB is an effective and well tolerated regimen for the patients with TNABC.
