DCs acquired by our reformed methods express both CD83 and CD 14 molecules highly, and have a higher density than other domestic reports. The higher TNF in DCs culture medium of HC patient suggests DCs in patient still have antigen presenting ability and by optimization the culture medium would improve its presenting ability and have a potential value in design and application individual vaccine. Although antigens pulsed DCs have a decrescent antigen presenting ability but BCG HSP70 could induce its mature and improve its presenting ability. Suggests BCG HSP70 would be a useful mature inducer. Lymphocytes primed by DCs based HC vaccine have the specific cytotoxicity against HCC lines. The CTL after freezing and anabiotic could prophylaxis and therapy HC xenograft on nude mouse. The results also suggests that CD4〓 lymphocytes play a important role in HC with a good differentiation and would be useful in treatment this kind of HC. After being activated by Peptide LLNQHACAV of hAFP and apoptotic HCCs pulsed DCs respectively, the culture medium of activated lymphocytes both contains a high level Th1 cytokines IL-12 and TNF. Primed lymphocytes appeared a characteristic of NK cells. DCs not only inhibited the growth of human HCC and other cancer cells in vitro but also prevented the growth of HC xenograft on nude mouse in vivo. There are at least three kinds of mechanism playing important role in DC based vaccine ,there are inhibition of DCs, HC specific CTL and cytokines pathway.

诱导出的DC共同表达CD83和CD14分子，CD83分子表达明显高于国内报道；肝癌患者DC培养上清中TNF水平高于健康人，提示肝癌患者DC仍具一定的抗原呈递能力，适当调控可使其行使APC功能，以期在肝癌个体化疫苗中发挥作用；DC负载肝癌可溶性抗原后，抗原呈递能力降低，BCG HSP70可促进DC成熟，增加其抗原呈递能力，预示BCG HSP70有可能成为促进DC活化和成熟的另一重要分子；肝癌DC疫苗在体外诱导肝癌特异性淋巴细胞，活化的淋巴细胞在体外对肝癌细胞的杀伤以特异性CTL为主，同时分泌较高水平Th1型细胞因子IL-12和TNF，并抑制4种肝癌细胞生长；冷冻复苏后的肝癌特异性淋巴细胞可以预防和抑制人肝癌裸鼠皮下移植瘤，提示DC负载肝癌可溶性抗原后诱发的MHC-Ⅱ类限制性CD4〓T细胞有可能在分化程度高的肝癌治疗中发挥作用；用DC和HLA-A2〓DC分别负载凋亡肝癌细胞和hAFP218-226位LLNQHACAV HLA-A2限制性九肽，在体外诱导肝癌特异性淋巴细胞，活化后的CTL细胞分泌较高水平的Th1型细胞因子IL-12和TNF，并具较强杀伤活性，此CTL同时具备NK细胞特征；DC对肿瘤细胞的抑制作用可能是通过吞噬实现的，Fas-L在DC抑制中也起一定作用；DC对人肝癌裸鼠皮下移植瘤的抑制率为97％；在肝癌DC疫苗的作用中，至少联合3种以上机制，即通过DC的直接作用、肝癌特异性CTL和细胞因子途径直接或间接地杀伤和抑制肝癌细胞。

Results showed sTGC-CM, which is similar with the effect of hTGC-CM, was able to induce human DPSCs to make odontoblastic changes as indicated by remarkable morphological changes, increased proliferation ability, higher multipotential and colony forming capability, and expression of some odontogenic markers in gene and protein levels,such as DSP, DSPP, DMP1, BSP, OCN, OPN.

结果表明：人牙髓干细胞经过一定时间的猪牙胚条件培养基诱导后，能在细胞形态上和细胞周期上发生改变，能具有更高的克隆形成能力和多向分化能力，能维持更好的干细胞特性，具有更强的增殖能力，表达更高水平的碱性磷酸酶，免疫组化和RT-PCR提示诱导后的牙髓干细胞能在蛋白水平和基因水平表达出一些牙向分化的标志，如DSP、DSPP、DMP1、BSP、OCN、OPN等。

通过采用测量法、数理统计等方法，对参加2006年全国田径锦标赛的我国各省、直辖市、自治区的高水平田径运动员共93人进行调查研究，研友我国高水平田径运动员认知风格的现状、影响因素及运动员的认知风格与所从事的项目、竞技水平的关系，从而为运动员的选材和训练提供依据。

In order to avoid these drawbacks, a design has been provided in which the driving chain is a round-link chain with horizontal links having a very small vertical and horizontal clearance of motion and with vertical links having a large vertical and horizontal clearance of motion in the hollowed section in which they are guided.

为了要避免这些不利点，设计已经被提供在哪一个推进的链是有一个运动的非常小垂直而水平清除的与水平的联编回合-联编的链和与有他们被指导的被挖空的区段的一个运动的大大垂直而水平清除的垂直的联编。

It's regarded as a dentin specific protein, The gene structure and the expression pattern of DSPP at transcript level are well known in recent years, however, the expression pattern of DSPP protein, and it's possible role during tooth development and dental pulp reparation after injury are not clear yet.

近年来，DSPP的基因结构及mRNA水平的表达模式已较清楚。蛋白印迹实验证实小鼠牙胚中有DSPP蛋白的存在。但是，DSPP在蛋白水平的表达模式如何？它的生物学功能和作用机制是什么？它在牙髓损伤修复中的作用又如何？目前国内外均未见报道。这些问题的研究，对我们在该蛋白后基因水平的了解具有重要意义，也为我们深入了解牙本质生物矿化机制、对牙体组织疾病和损伤进行生物性防治提供理论依据。

The TPH pollutants of non-rhizosphere decompositted differently in environment with plant. The gradation rate of low concentrate pollutants was much higher than that of high pollutants level. The decomposition rate of TPH pollutants in rhizosphere was higher than that in non-rhizosphere, and the rhizosphere effect deceased with degree of pollution.

在有植物存在的条件下，非根际土壤石油污染物降解的变化表现为：在低污染水平，污染物的降解率明显高于高污染水平，根际土壤的降解率高于非根际土壤的降解率，且随着污染水平的提高，植物的根际效应减弱。
