The recognition mechanisms of GGR and TCR to UVB-induced photodamages were summarized: Xeroderma Pigmentosum group C, the recognition factor in GGR, executed its function avoiding direct contacting with lesions; the conversion between monomer and dimer of Cockayne syndrome B protein was underlined in the recognition of TCR; ubiquitylation mediated by DNA damage binding protein played an important role in NER recognization at chromatin level; moreover, the fate of the recognition factors was also discussed.

识别因子XPC通过一种不直接识别损伤本身的机制在GGR识别过程中发挥作用；在TCR识别过程中强调了关键因子CSB单体及二聚体两种形式的转换。在染色质水平上，DDB介导的泛素化作用是NER识别过程中重要的调控要素。另外，完成使命的识别因子的最终走向也是NER途径中的一个重要环节。通过分析上述生化过程，较清楚地总结了GGR及TCR对UVB导致的光损伤的识别机制。

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。

A univariate ANOVA is executed to analyze the influencing factors of the production cost by dividing it into direct material, direct labor cost, indirect cost and total cost separately. It is found that the variables of farm scale and crop type show significant impacts in the direct labor cost and total production cost. The one-crop farming variable makes significant difference in the total production cost; whereas different planting ways differentiates the indirect cost. In addition, years of farming, farmer's age, and full-time status all make no significant difference in all aspects of production cost.

此外，将农场生产成本分为直接材料、直接人工、间接成本、总生产成本四面向进行多因子变异数分析，结果发现耕作面积、作物类型变项仅在有机农场的直接人工和总生产成本中有显著差异；有机农场是否为单一经营在总生产成本上有显著差异；不同栽培方式的有机农场仅在间接成本的高低上有显著差异；此外，而耕作年数变项因本研究有机农场耕作年数较高之样本特性影响，导致该变项对生产成本并无显著的差异；年龄、专兼业经营等变项在生产成本上高低并无显著差异。

Transcription factors can control the transcription of their target genes when they bind to the DNA-binding sites on their promotors. They can transfer the messages of growth factors and so on to those effective molecules. Core binding factor al is such a kind of transcription factor, which can control the differentiation of osteoblasts peculiarly. They can induce the pro-osteoblasts or non-osteoblasts to synthesize and secrete most mineralize related proteins such as ALP, OC, OPN, BSP and so on, in order to differentiate to osteoblasts finally.
