目的评价不同炮制方法对黄药子抗胃癌作用及其肝毒性的影响。方法80只小鼠随机分为空白对照(Ct)组、黄药子生品(RD)组、清炒黄药子(FD)组、酒炙黄药子(WD)组、当归煎汤炙黄药子(2∶1)(ASR2∶1DB)组、黄芪煎汤炙黄药子(1∶2)(AR1∶2DB)组、黄芪煎汤炙黄药子(1∶1)(AR1∶1DB)组、黄芪煎汤炙黄药子(2∶1)(AR2∶1DB)组,每组各10只,各组均以1.7g·kg^(-1)剂量灌胃给予对应炮制药物,连续14d,Ct组给予等量生理盐水。观察和比较各组肝脏病理形态学变化。体外培养人胃癌细胞MKN-45,以各组含药血清处理,CCK-8法检测细胞增殖情况。结果病理形态学变化表明各炮制组均造成了不同程度的肝脏损伤,各给药组肝脏病变损害程度按由轻到重依次为AR2∶1DB、ASR2∶1DB、AR1∶1DB、AR1∶2DB、FD、WD、RD组,以RD组损害最为严重;CCK-8实验结果表明AR1∶1DB、AR2∶1DB、ASR2∶1DB组可不同程度抑制人胃癌细胞MKN-45增殖(P<0.05),以AR2∶1DB组作用最强(P<0.001)。FD、WD、AR1∶2DB组间人胃癌细胞MKN-45增殖抑制作用无统计学差异;结论黄芪煎汤炙黄药子炮制法可增强黄药子体外抗胃癌活性并减少其对肝脏的损害,药效有剂量依赖性,随着黄芪在药对中所占的比重增大而增强,以2∶1组效果最佳,其机制可能与增强抗氧化及清除自由基作用有关。

Exploring two-dimensional(2D)magnetic semiconductors with room-temperature magnetic ordering and electrically controllable spin-polarization is a highly desirable but challenging task for ***,through first-principles calculations,we propose to realize such a material by exfoliating the recently synthesized organometallic layered crystal Li0.7[Cr(pyz)_(2)]Cl0.7·0.25(THF)(pyz=pyrazine,THF=tetrahydrofuran).The feasibility of exfoliation is confirmed by the rather low exfoliation energy of 0.27 J m^(−2),even smaller than that of *** exfoliated Cr(pyz)_(2)monolayers,each pyrazine ring grabs one electron from the Cr atom to become a radical anion,and then a strong d-p direct-exchange magnetic interaction emerges between Cr cations and pyrazine radicals,resulting in room-temperature ferrimagnetism with a Curie temperature of 342 ***,the Cr(pyz)_(2)monolayer is revealed to be an intrinsic bipolar magnetic semiconductor where electrical doping can induce half-metallic conduction with controllable spin-polarization direction.

目的探讨单孔或多孔胸腔镜肺叶切除术对非小细胞肺癌患者肺功能和康复进程的影响。方法选择玉溪市人民医院胸外科2019年1月-2024年1月收治的300例非小细胞肺癌患者为研究样本,均接受电视胸腔镜肺叶切除术,根据术式分为单孔组和多孔组各150例,观察对比两组患者肺功能指标、康复指标和并发症发生率。结果两组患者术前各项肺功能指标对比,差异不明显(P>0.05);术后1个月各组患者肺功能指标均降低,单孔组MVV、PEF、FEV1/FVC均高于多孔组(P0.05)。单孔组并发症发生率低于多孔组(P<0.05)。结论单孔胸腔镜下肺叶切除术虽然手术难度大,但具有微创优势,可减轻术后疼痛,改善患者肺功能,缩短康复进程,与多孔法相比实用价值更高。

This study evaluated the bioaugmentation potential of a quinoline-degrading strain Pseudomonas citronellolis lv1 inoculation into activated sludge for treating quinoline wastewater, and results indicated the inoculation of lv1 in aerobic continuous MBBR could substantially improve the quinoline removal performance with an improved removal efficiency of 34% averagely when quinoline was used as the sole carbon and nitrogen source. Additionally, efficient removal of quinoline in enhanced MBBR occurred at the influent p H of 7.0–8.0, hydraulic retention time(HRT) of 24–28 h and influent quinoline concentration of 100–700 mg·L^(-1). High-throughput sequencing analysis indicated that bioaugmentation could increase microbial diversity and shape the microbial community structure. Although the inoculant lv1 did not remain its dominance in stage Ⅲ, bioaugmentation indeed induced the formation of effective microbial community, and the indigenous microbes including Flavobacterium, Pseudoxanthomonas,Pseudomonas, Vermamoeba, Dyadobacter and Sphingomonas might play the key role in quinoline *** to the PICRUSt, the enhanced genes encoding aromatic ring-cleavage enzyme, especially for Nheterocyclic ring-cleavage enzymes, could lead to the improved removal performance of quinoline in bioaugmentation stage. Moreover, the enhanced MBBR treated well actual coking wastewater, as indicated by high removal performance of quinoline, phenol and COD.

Mechanical property of coarse grained and nano/ultrafine grained alloy 690 and their corrosion resistance after immersion in high temperature borate buffer solution were investigated. The grain refinement significantly enhances the tensile strength of the alloy 690. In addition, the grain refinement facilitates the formation of the deformation twin which improves the ductility of the alloy 690. It has been found that the grain refinement promotes to form more Cr2 O3 on the surface of the alloy 690 in high temperature borate buffer solution. At the same time, the grain refinement inhibits the formation of spinel type *** hematite type oxides formed on nano/ultrafine grained alloy 690 improves its corrosion resistance in borate buffer solution. The hematite type oxides have a lower concentration of point defect than that of the spinel type oxides, which results in an excellent corrosion resistance of nano/ultrafine grained alloy 690. These results are supported by the Mott-Schottky analysis and the point defect model.
