Research on the Fiscal and Taxation Policy for Boosting China’s Pension Service Industry

中国的老龄人口数居世界各国之首且老龄化程度日益加深，实行了三十余年的计生政策导致家庭小型化，严重弱化了家庭养老功能，加之我国养老服务业发展起步晚、发展慢且发展不平衡，使得满足社会养老服务需求的任务显得越发紧迫而艰巨。养老服务业作为养老产业的重要组成部分，其产品具有准公共产品的特性，需要国家政策的支持和帮扶，才能获得社会资源的有效配置。本文从财税的视角出发，依据财税政策对于产品供给和需求的影响理论，通过借鉴东、西方一些代表性国家扶持养老服务业发展的财税政策经验和分析国内现行扶持养老服务业发展的财税政策实施效果，从增加养老服务供给和保障养老服务需求两方面入手，探求能更有效契合养老服务供给方与需求方...China has the largest ageing population in the world and the aging problem has become more and more prominent nowadays. China's one-child policy has been in force for more than 30 years, leading to family miniaturization as well as weakening family supporting ability. In addition, due to the late start, slow and unbalanced development of Chinese pension service industry, the task of meeting the de...学位：税务硕士院系专业：经济学院_税务硕士学号：1552013115189

Study on Securities Investor Protection Fund System

证券投资者保护基金作为证券市场上投资者保护制度的重要组成部分，在预防、化解和处理金融危机，保护投资者利益和维护金融安全等方面的功能得到了普遍认可。随着金融体制改革的深化和不断完善，我国开始建立了证券投资者保护制度，但对保护基金的研究仍然是个别的、零散的，缺乏系统性和深入性。本文着眼于我国现行的证券法律制度，立足于我国投资者利益保护现状，通过法条研究、理论论证，并在对美国和我国香港地区的投资者保护基金制度分析借鉴的基础上，从运行模式、资金来源、赔偿机制等方面分析我国的证券投资者保护基金制度，以期不断完善。本文主文共有三章。具体内容如下：第一章主要介绍了证券投资者保护基金的一般理论。从证券投资者保...As an important composition of the investor protection system in the securities market, securities investor protection fund is widely recognized in preventing and dealing with financial crisis, protecting the interests of investors, and safeguarding the financial order. Along with the development of the finance system reform, the system of securities investor protection fund is being established i...学位：法学硕士院系专业：法学院法律系_经济法学学号：20030809

A Study on Optimization of Industry Organization Structure and Multi-layer Capital Market System

当前我国产业组织具有“散”、“全”、“低”的特征，严重影响了企业竞争力和社会资源配置效率。而推进我国资本市场的多层次发展，对于加快我国经济体制改革进程，拓展不同规模企业融资渠道，优化产业组织结构，提升产业竞争力具有十分重要的作用。本文首先采用SCP范式回顾了我国产业组织演化过程及现状，提出了我国产业组织结构调整的目标模式；重点考察了资本市场层次与产业组织结构优化的互动关系，提出多层次资本市场建设对于优化我国产业组织结构的重要意义。 结合我国资本市场现状和存在的问题，本文分析了产业组织低效率的主要原因，指出构建多层次的资本市场才是解决优化产业组织结构，提升产业竞争力的出路所在。为了借鉴国际上的...At present, industry organization of China has the characteristic of dispersion, full scale and low level, which affect enterprise competition. Multi-layer capital market has the function to expedite economy reform, develop channel of enterprise financing and advance competition of industry.

pJAK2 polypeptide,an antagonist of suppressors of cytokine signaling-1,can enhance the antitumor effect of dendritic cells

目的:探讨细胞因子信号转导抑制因子-1(SuPPrESSOrS Of CyTOkInE SIgnAlIng1,SOCS1)拮抗物PJAk2多肽(氨基酸序列号为1001-1013)参与树突状细胞(dEndrITIC CEllS,dCS)的体外诱导培养后对dCS抗肿瘤作用的影响。方法:采集健康人外周血,离心获得单个核细胞,用重组人粒细胞巨噬细胞集落刺激因子(rECOMbInAnT HuMAn grAnulOCyTE-MACrOPHAgE COlOny STIMulATIng fACTOr,rHgM-CSf)及重组人白细胞介素-4(rECOMbInAnT HuMAn InTErlEukIn-4,rHIl-4)诱导dCS,第5天分为4组:单纯dCS培养(对照)组、抗原负载(lySATE-dCS)组、多肽修饰(PJAk2-dCS)组和抗原与多肽共培养(lySATE+PJAk2-dCS)组,第6天各组加入肿瘤坏死因子-α(TuMOr nECrOSIS fACTOr-AlPHA,Tnf-α)促成熟。倒置显微镜下观察dCS形态;fCM法检测dCS表型;乳酸脱氢酶(lACTATE dEHydrOgEnASE,ldH)细胞毒实验检测各组细胞毒性T淋巴细胞(CyTOTOXIC T lyMPHOCyTE,CTl)对胃癌细胞bgC-823的靶向杀伤作用;ElISA法检测白细胞介素-12(InTErlEukIn-12,Il-12)和γ干扰素(InTErfErOn-γ,Ifn-γ)的水平。结果:与未加入诱导剂组相比,各组均成功诱导出成熟dCS,均高表达Cd80、Cd83、Cd86和人类白细胞dr抗原(HuMAn lEukOCyTE AnTIgEn dr,HlA-dr),但以lySATE+PJAk2-dCS组的表达水平最高。在10:1~30:1的效靶比范围内,CTl杀伤作用与效靶比呈正相关。当效靶比为30:1时,对照组的CTl杀伤率达(19.77±2.34)%,低于其他3组(P<0.01),而lySATE+PJAk2-dCS组较lySATE-dCS组及PJAk2-dCS组都高(P<0.05)。lySATE+PJAk2-dCS组培养上清液中Il-12及Ifn-γ的分泌水平明显高于对照组(P<0.01)。结论:SOCS1拮抗物PJAk2多肽(1001-1013)可增强dCS对胃癌细胞的抗原递呈及特异性抗肿瘤作用。Objective:To investigate the effect of pJAK2 polypeptide,an antagonist of SOCS1(suppressors of cytokine signaling 1),on antitumor effect of in vitro cultivation-induced DCs(dendritic cells).Methods:Peripheral blood was collected from the healthy volunteers,and the PBMCs(peripheral blood mononuclear cells)were isolated.DCs were induced by rhGM-CSF(recombinant human granulocyte-macrophage colony-stimulating factor)and rhIL-4(recombinant human interleukin-4).On the fifth day,DCs were divided into four groups:control group,Lysate-DCs group,pJAK2-DCs group,and Lysate + pJAK2 DCs group.On the sixth day,TNF-α(tumor necrosis factor-alpha)was added into each group.The morphological features of DCs were observed under an inverted microscope;the phenotypes were detected by FCM(flow cytometry);the killing effect of CTLs(cytotoxic T lymphocytes)on gastric cancer BGC-823 cells was evaluated by LDH(lactate dehydrogenase)cytotoxicity test;the concentrations of IL-12(interleukin-12)and IFN-γ(interferon-γ)were detected by ELISA(enzyme-linked immuno sorbent assay).Results:Mature DCs presented typically morphological and phenotypic features;the DCs in Lysate + pJAK2-DCs group had the highest expression levels of CD80,CD83,CD86 and HLA-DR(human leukocyte antigen DR).When the ratio of effectors to target cells ranged from 10:1 to 30:1,the killing activity of CTLs had a positive correlation with the ratio.When the ratio of effectors to target cells was 30:1,the killing activity of CTLs in the control group was(19.77±2.34)%,which was lowest as compared with the other groups(P < 0.01),meanwhile the killing activity of CTLs in Lysate + pJAK2-DCs group was higher than those in Lysate-DCs and pJAK2-DCs groups(P < 0.05).The levels of IL-12 and IFN-γ secretion in Lysate + pJAK2-DCs group were apparently higher than those in the control group(P < 0.01).Conclusion:An antagonist of SOCS1,pJAK2 polypeptide,can enhance the ability of antigen presentation and specific antitumor effect of DCs on gastric cancer cells.南京军区医学科技创新课题资助项目(编号:10MA068); 福建省自然科学基金面上项目(编号:2010D013); 厦门市科技计划创新项目(编号:3502z20104014

以筛选得到的Schizochytrium sp.菌株作为研究对象,考察了培养基碳源、氮源对该菌株生物量的影响,通过响应面法建立了菌体生物量与葡萄糖、酵母粉以及玉米浆浓度之间的关系,得到较佳培养基组成为:126g/L葡萄糖、10g/L酵母膏、2g/L玉米浆、5g/L蛋白胨、0.5倍浓度自然海水1L。摇瓶发酵结果表明:在5d培养时间,Schizochytriumsp.生物量、积累油脂以及DHA分别可达42.9、34.1、13.8g/L。One strain of Schizochytrium sp.was selected as the mode microorganism to evaluate the influences of carbon and nitrogen resource on the biomass.By employing response surface method,the relationship between biomass and nutrients was founded and the optimized culture medium for Schizochytrium sp.was determined.The optimized medium consisted of 126 g/L glucose,10 g/L yeast extract,2 g/L corn steep liquor,5 g/L soy peptone and half the salt concentration of seawater 1 L.The maximum biomass,total fatty acid and DHA reached 42.9 g/L,34.1 g/L and 13.8 g/L on the optimized culture medium after 5 days incubation,respectively

Remained or Repealed of Penal Code 306:Listen to the Legal Professional Persons' Opinions

刑法第306条(又称律师伪证罪)从其诞生之日起就面临着当存还是当废的巨大争议,这些争议或来自学理或来自实践中的相关利益群体。2009年底至2010年初的李庄案再次使得这一争论从幕后转至台前。通过考察法律职业人对第306条的真实态度,可以深入地发掘争议背后的社会因素:即司法机关观念上的误区;诉讼结构的不合理;追诉程序上的瑕疵,从而从实体和程序上为刑法第306条的未来寻求一条理性的出路———存而慎用。Penal Code 306 has been faced with controversy which should be remained or be repealed all the times from its birth which is from theories or interests groups in practice.This controversy is made from backstage to stage because of case of Li Zhuang which happened from late 2009 to early 2010.We can deeply explore the social factors behind the controversy : misunderstanding of judicial organization;unreasonable of criminal structure;and defect of prosecution procedure through investigating the legal professional persons' attitude to Penal Code 306 to find a reasonable way for the Penal Code 306' s future——remained and applied cautiously.美国麦克阿瑟基金会研究项目---

邓小平理论体系构建的几个特点

邓小平理论的科学性与其构建理论体系方法的科学性是分不开的 .作为建设有中国特色社会主义这个意义上的邓小平理论 ,它的理论体系的构建有以下几个特点 :一、以“社会主义初级阶段”概念为逻辑起点 .“实事求是”不是逻辑起点 ,而是研究遵循的科学方法 ;二、从生产力高度来认识社会主义和构建社会主义理论 ;三、“猫论”与“摸论”结合的思维方式 ,突破了单纯演绎思维的局限 ,又使非演绎思维沿着正确的方向进行 .从而使社会主义理论得到创
