AIM： To characterize the role of flgK and its protein product in Hpylori colonization. METHODS： The PCR cloning method identified the flgK gene. An isogenic flgK mutant was constructed by gene replacement and confirmed by Southern blot analysis and PCR analysis. The recombinant FlgK protein （r-FlgK） was purified. Electron microscopy （EM） was applied to demonstrate the flagella of H pylori. An in vitro motility test was assessed in semisolid medium. The densities of H pylori colonization with either the wild-type strain or its flgK mutant were compared among BALB/c mice with or without pre-immunization with r-FlgK. The serological responses to r-FlgK were analyzed for 70 clinical patients with different densities of H pylori colonization. RESULTS： From a duodenal ulcer strain, the flgK gene was cloned and it contained 1821 bp, with a 95.7% identity to the published sequences. No flagella were observed under EM for the mutant strain, which had a loss of motility. Hpylori density was lower in the BALB/c mice inoculated by the mutant or with pre-immunization with r-FlgK compared to unimmunized mice or mice inoculated by the wild-type strain （P 〈 0.05）. In the H pylori-infected patients, the serological responses to r-FlgK were uniformly low in titer.CONCLUSION： FlgK encoded by flgK is important for flagella formation and H pylori motility. Deficiency in FlgK or an enhanced serological response to r-FlgK can interfere with Hpylori colonization. FlgK of Hpylori could be a novel target for vaccination.

The use of a biodegradable natural plant-based surfactant extracted from soapberry is proposed for the remediation of Ni, Cr and Mn from industrial soil site in Hai-Pu, Taiwan. Batch experiments were performed under variation of fundamental factors （saponin concentration, pH, and incubation time） for metal remediation. Removal of Ni and Mn were increased with increasing saponin concentration （0.015-0.150 g/L）, whereas the removal of Cr was increased upto 0.075 g/L saponin. The Ni, Cr and Mn were removed significantly （p 〈 0.05） at near to the neutral and slightly acidic （pH 5 to 8） conditions. Removal efficiency of Ni （99%） from the soil was found to be greater than that of Cr （73%） or Mn （25%） in the presence of saponin at a concentration of 0.150 g/L at pH 5. The removal percentage increased with incubation time where the removal of Ni was faster than that of Cr and Mn. The result indicates the feasibility of cco-friendly removal of heavy metal （Ni, Cr and Mn） from industrial soil by soil washing process in presence of plant derived saponin.

儿童照料费用对女性劳动参与决策的影响研究

自我国开始市场化改革以来,我国女性劳动参与率呈现不断下降的趋势,且长期低于男性劳动参与率。受传统家庭劳动分工的影响,女性在家庭中承担着养育孩子的主要责任,因而与儿童照料相关的成本负担通常会对女性劳动供给产生一定的负面影响。在我国进行托育制度改革后,公共托育体系的瓦解抬高了儿童托育服务的价格。目前,我国女性劳动参与率的持续下降与儿童照料费用的不断增加有着密切联系。基于此观察,利用中国健康和营养调查(CHNS)1991~2015年九期调查数据,创新性地利用了社区0~6岁儿童托幼机构的托儿费支出这一指标,综合使用Probit模型和工具变量法实证分析了儿童照料费用对我国女性劳动参与决策的影响。研究结果发现:儿童照料费用的增加显著降低了女性的劳动参与率。异质性分析表明,儿童照料费用的增加对于城镇、受教育程度较低、30岁以下和中低收入水平家庭的女性劳动参与率的负面影响更为明显。稳健性分析表明,儿童照料费用的增加对男性劳动参与率没有显著的负面影响;在控制内生性后,儿童照料费用对女性劳动参与率的负向影响显著增强。在生育政策完全放开的背景下,完善普惠托幼服务体系、健全女性就业保障制度和倡导男性共同承担育儿责任是提升我国女性劳动参与率的重要措施。

境外某铜金矿千米深竖井在通过膨胀性软破岩层(泥灰岩)时,围岩遇水膨胀压力极大,先后出现两次井壁垮塌和开裂的情况,对施工进度及施工人员安全产生极大影响。为解决该问题,查找相关文献资料及国内外类似施工案例,对通过膨胀性软破岩层的井壁破裂机理进行分析,针对性地制定井壁破裂修复方案;在此基础上,进一步调查施工地点的工程地质和水文地质情况,通过分析与总结,提出深竖井不良岩层的施工及分级支护方案,对其所穿过的膨胀性软破岩层的围岩制定分级表,根据不同岩体等级分别提出相应的施工及具体支护方案。通过对两次破裂处井壁的修复,较长时间内未出现裂缝及漏水现象,修复效果良好,达到预期;此外,竖井井筒后续施工中在采用分级支护方案后,井筒顺利通过厚度超过500 m的不良岩层,且在工期、质量、安全三个方面都取得良好效果,保障该深竖井工程的施工质量与施工安全。该工程为膨胀性软破岩层中的深竖井掘进施工积累了宝贵经验,对类似工程具有一定的借鉴意义。
