田赋既是传统时代国家财政收入的主要来源,也是政治国家在地方社会统治的象征。因而,在同治、光绪两朝两次区域社会大动荡后,清朝迅即着手田赋清厘,力图规复旧制,以维正供。尽管清朝对循化厅向来实施"轻徭薄赋"之策,但受人口流散、土地... 详细信息

田赋既是传统时代国家财政收入的主要来源,也是政治国家在地方社会统治的象征。因而,在同治、光绪两朝两次区域社会大动荡后,清朝迅即着手田赋清厘,力图规复旧制,以维正供。尽管清朝对循化厅向来实施"轻徭薄赋"之策,但受人口流散、土地荒芜等因素影响,田赋征收并不理想,积欠严重,只能寄希望于国家蠲免。田赋蠲免则有效地减轻了田赋负担,促进了生产恢复与发展,反映出清政府在循化厅田赋征收中的务实性与灵活性,具有一定的积极意义。

1929年南京国民政府颁布的《工厂法》,是20世纪20年代末30年代初工人生存状况十分恶劣、劳资矛盾尖锐、工人运动勃兴及国际国内社会舆论所造成的压力与推力的结果,在一定程度上反映了南京政府初期秉承孙中山新三民主义、维护劳工权利的... 详细信息

1929年南京国民政府颁布的《工厂法》,是20世纪20年代末30年代初工人生存状况十分恶劣、劳资矛盾尖锐、工人运动勃兴及国际国内社会舆论所造成的压力与推力的结果,在一定程度上反映了南京政府初期秉承孙中山新三民主义、维护劳工权利的初衷。该法具有移植性、继承和超越性、超前性等特点。它的制订使民国法制更趋完备,也将现代国家的建构向前推进了一步。

在地表能量辐射平衡理论分析的基础上,从岩石热传导、土壤热传导以及煤层气储层影响热导率等方面分析了地下热传导,探讨了地球内部热量传递导致地表温度异常的原因。选择河南焦作煤层气富集区作为热红外遥感监测靶区,运用ASTER热红外遥感数据进行温度反演。首先利用大气辐射传输模型MODTRAN 4进行大气校正获得大气透过率,然后根据NDVI计算地表比辐射率,最后采用分裂窗简化算法反演地表温度。结果表明:研究区温度反演最低为296.62 K,最高为302.67 K,部分研究区呈现显著温度异常。通过分析该区域温度异常的不同原因,注意到富含煤层气对应的靶区呈现温度异常,根据地下热传导机理,据此推断该靶区温度异常是由于地下煤层富含煤层气从而导致地下热导率低于周围地层的热导率所致,该结论仍需要应用其他手段进一步验证。

Open Journal of Geology 2019年第10期9卷 646-649页

A well preserved terrestrial Cretaceous succession outcrops in Shandong Province. Although previous studies have conducted much work on the geochronology, subdivision of stratigraphic units, regional correlation and paleontology, high controversies remain about geochronology, subdivision of stratigraphic units and sedimentology. Here, we report a synthesized study of the Cretaceous successions and stratigraphy in Shandong based on the new results. Accordingly, reconstruction of framework of the Cretaceous stratigraphy in Shandong is summarized as, in descending order, the Mengyin Group of the Jurassic/Cretaceous transition, the Lower Cretaceous Laiyang Group, Qingshan Group, Dasheng Group and the Upper Cretaceous Wangshi Group.

在资源受限的无线传感器网络中,低质量的无线链路严重限制了其大规模应用。基于WSN监测信号普遍具有的稀疏特性,提出了基于双层压缩感知(double process of compressive sensing)的有损无线链路稀疏信号传输架构,探索低质量无线链路下实时、高精度和高能效的稀疏信号传输方法。首先,将稀疏信号传输过程中的随机分组丢失现象建模为压缩感知的线性降维观测过程(被动CS过程)。然后,针对WSN为提高传输效率而采用的长数据分组,数据发送前在发送端引入线性随机降维投影——简易的信源编码操作(主动CS过程),避免块状数据丢失的发生。最后,接收端根据收到的有损数据利用压缩感知的方法重构原始信号。进一步根据压缩感知重构和无线通信的相关原理,推导出允许使用的发送端最小压缩率和最大分组长度。大量仿真实验表明,所提方法不仅可以保证数据的可靠准确传输,还能减小发送数据量,降低传输时延和节点能耗。

Lipid nanoparticles (LNPs) are non-viral nucleic acid delivery systems that show great potential in vaccine development and disease treatment. Although LNPs are particularly advantageous for in vivo delivery, the wide application of LNPs is impeded as their systemic delivery of nucleic acid drugs to extrahepatic tissues remains highly challenging. To address this issue, we developed lung-targeted polyzwitterionic LNPs with zwitterionic polymer poly(2-methyacryloyloxyethyl phosphorylcholine)(PMPC) modified 1,2-dimyristoyl-sn-glycerol lipid for the delivery of small interfering RNA (siRNA). Three libraries with 90PMPC-LNPs@siRNA were established. The polyzwitterionic PMPC-LNPs had high siRNA encapsulation efficiency of about90%. The findings revealed that polyzwitterionic PMPC-LNPs@siRNA absorbed protein corona with the main component of Vitronectin, mediating lung-targeted delivery of siRNA. With good cellular uptake and endo/lysosomal escape ability, in vitro and in vivo studies demonstrated that polyzwitterionic PMPC-LNPs with siRNA against tumor necrosis factor-α (TNF-α) could significantly down-regulate the TNF-α in mRNA and protein levels, and improved the pathological features of lung inflammation. Polyzwitterionic PMPC-LNPs@siRNA achieved safe and efficient treatment of lung inflammation. Therefore, this work offered a promising siRNA therapeutic approach for lung diseases.

Chinese Journal of Integrative Medicine 2018年第11期24卷 867-872页

Objective： To assess the effectiveness of Yishen Jiangu Granules（益肾健骨颗粒, YSJGG） on aromatase inhibitor-associated musculoskeletal symptoms（AIMSS）. Methods： A single-arm, open-label study was conducted in 34 postmenopausal women with breast cancer who experienced AIMSS. Patients were treated with YSJGG for 12 weeks（12.4 g orally twice daily）. The primary outcome was a change in the mean worst pain score of Brief Pain Inventory-Short Form（BPI-SF） over 12 weeks, and the second outcomes included changes in pain severity and pain-related interference of BPI-SF and Western Ontario and McMaster Universities Osteoarthritis Index（WOMAC）, Modified Score for the Assessment of Chronic Rheumatoid Affections of the Hands（M-SACRAH）, the Functional Assessment of Cancer Therapy-Breast（FACT-B）, bone mineral density（BMD） and blood indices such as calcium（Ca）, phosphate（P）, and alkaline phosphatase（ALP）. Results： Of 37 women recruited, 30 initiated the therapy and 24 were evaluable at 12 weeks. The primary outcome（BPI-SF worst pain scores） achieved a 2.17-point reduction compared with baseline（5.75±1.87 vs 3.58±2.15, P〈0.01）. There were reductions in pain severity（decreased 1.65, P〈0.01） and pain-related interference（decreased 2.55, P〈0.01）. The changes in WOMAC and M-SACRAH scores were similar to BPI-SF（P〈0.05）. In the FACT-B, only physical wel-being and functional wel-being were improved compared with baseline（P〈0.05）. No clinical differences were found in BMD, Ca, P and ALP. Conclusion： YSJGG is an effective and wel-tolerated agent to reduce AIMSS.
