本文立足我国人口非均衡分布的典型事实,利用省级面板数据分别构建静态面板模型和空间计量模型检验投资强度和经济服务化等因素对人口集聚水平的影响效应。研究结果发现:投资强度和经济服务化均对人口集聚具有显著促进作用,其中,投资率的提高有利于加速人口集聚,但人口集聚优势的形成更依赖于资本长期积累的规模和密度;经济服务化是扩大地区就业吸纳潜力的重要途径,进而能够显著推动人口集聚进程;高投资强度和高经济服务化地区能够产生人口虹吸效应,并同时存在拥挤效应和辐射效应,从而有利于带动周边地区形成区域化人口集聚优势。因此,常态化区域“人口竞争”趋势将不断增强,城市群发展将成为我国人口集聚格局的重要载体;中西部等欠发达地区人口集聚能力短期内仍无法与东部发达地区抗衡,但区域协调发展战略的实施为缩小区域差距、优化人口分布提供了战略机遇;欠发达地区应以城市群建设为突破口,因地制宜、循序渐进同步推进资本积累和产业升级,培育高效、绿色、可持续的人口集聚竞争力。

BACKGROUND: Active immunotherapy has been successful in preventing many infectious diseases, and is being explored for its anti-tumor use. Purified antigens, peptides, gene-based systems and antigens contained in whole cells or cell lysates are used in specific active immunotherapy for cancer, known as cancer vaccines. Cancer vaccines do not directly kill tumor cells, but prime a specific humoral and/or cellular immune response against the tumor. Up to date, many kinds of cancer vaccines have been tested in the world and have shown their own advantages. Heat shock protein (HSP)-based cancer vaccine is one of the outstanding representatives. In this paper, we review recent advances in HSP-based cancer vaccines. DATA SOURCES: An English-language literature search was conducted using MEDLINE (1990-2005) on HSP, cancer vaccines and other related subjects. RESULTS: Several kinds of HSP-based cancer vaccines which have been explored worldwide, include tumor derived HSP-pepdde complex cancer vaccines, artificially reconstituted HSP-peptide complex cancer vaccines, HSPpeptide fusion protein cancer vaccines and HSP-based DNA cancer vaccines, etc. Many HSP-based cancer vaccines are being tested in clinical trials, and some are being tested in phase Ⅲ clinical trials at present. CONCLUSION: The available results in preclinical tests and clinical trials indicate that HSP-based cancer vaccines are promising in cancer therapy.

Low-temperature fabrication of black-phase CsPbI3 perovskite films is first demonstrated by using diphenylphosphinic chloride additive under 30-50 degrees C, arising from the steric effect and chloride insertion ***-area high-quality all-inorganic perovskite films with fewer defects enhanced crystallographic orientation, and excellent environmental stability is *** record performances are demonstrated for flexible wearable photodetectors with a responsivity of 42.1 A W-1, a detectivity of 1.3 x 1014 Jones, high-fidelity image, photoplethysmography sensor functions, and high mechanical stability. Flexible wearable optoelectronic devices fabricated from organic-inorganic hybrid perovskites significantly accelerate the development of portable energy, biomedicine, and sensing fields, but their poor thermal stability hinders further applications. Conversely, all-inorganic perovskites possess excellent thermal stability, but black-phase all-inorganic perovskite film usually requires high-temperature annealing steps, which increases energy consumption and is not conducive to the fabrication of flexible wearable devices. In this work, an unprecedented low-temperature fabrication of stable black-phase CsPbI3 perovskite films is demonstrated by the in situ hydrolysis reaction of diphenylphosphinic chloride additive. The released diphenyl phosphate and chloride ions during the hydrolysis reaction significantly lower the phase transition temperature and effectively passivate the defects in the perovskite films, yielding high-performance photodetectors with a responsivity of 42.1 A W-1 and a detectivity of 1.3 x 1014 Jones. Furthermore, high-fidelity image and photoplethysmography sensors are demonstrated based on the fabricated flexible wearable photodetectors. This work provides a new perspective for the low-temperature fabrication of large-area all-inorganic perovskite flexible optoelectronic devices.
