After a further analysis based on the empirical results,a trial probe on the cognitiveprocessing mechanism of the problem representation of the word problem in two types of MLDwas made by the author.The MRD performed much poorer than the MLD only in the mostdifficult equation listing of word problem and the medium and most difficult problemrepresentation of word problem,which showed no difference in computation and comprehensionof simple meaning of the problem,but the gap between two types of MLD became wide as afunction of difficulty and cognitive loading.It indicated that the MLD only had some advantage over MRD for they used more cognitive skills to solve the problem.

基于以上实验的结果，对两类数学困难小学生的应用题问题表征的认知机制作如下推断：混合型数学困难学生仅在高难度水平的应用题列式成绩和中高难度水平应用题问题表征水平上比单纯型数学困难学生得分显著低下，表明两类数学困难小学生在计算能力与理解简单题意的能力上并无差异，但随着难度提高，认知负荷加重，两类数学困难学生在应用题解题上的差异得以突显，表明当需要运用更多的认知能力解决问题时，单纯型数学困难学生比混合型困难学生更具优势。

Genetic cluster analysis is similar based on the results of morphological and DNA markers, the five populations could be divided into three groups. But there are different groups sort of individual locations, reflecting the similarities and difference about the analysis of the relationship between population with the two kinds of markers, It could be concluded that there was coupling and relevance to some extent in evaluating genetic diversity with the same experiment sampling by morphological and SSR marker variation. However, there was also differences. In research, the two can complement each other.8. Identification of Genetic Relationship of Amygdalus plants by SSRThe genetic relationship among 55 Amygdalus plants collections, belonging to 6 species and collected from both homeland and abroad were identified via SSR molecular marker technique.

新疆野扁桃遗传多样性不同研究分析方法结果的比较与评价表型与DNA二种水平的遗传标记方法揭示的遗传多样性水平有差异，表型性状比DNA分子标记具有更大的变异性；其受到环境的影响较大，也即对环境更敏感。2种水平的遗传标记聚类结果将野扁桃5个不同分布群体均可分为3个大类群，但是出现有个别不同的群体排序位置，反映了2种标记在分析种群间关系上的异同性，从本研究结果来看，说明表型与DNA标记有一定的耦合性和相关性，但也存在差异，在研究上可以互为补充。8。

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。

The NO content and the NOS activity were down in the PIH pregnant women placenta.This showed that the ghrelin regulated the VEGF and influenced the the NO down.And the placenta angiospasm,blood pressure highten, and the PIH were caused also by this. The ghrelin,VEGF,Flt-1,NO and NOS were detected by the SP-immunochemistry, RQ-PCR,cell culture in vitro,ASODN and nitrate reductase in the normal pregnancy,PIH placenta and the cultured HUVEC antisense blocking ghrelin in vitro.

结果证实：PIH孕妇胎盘组织中Ghrelin，VEGF、Flt-1蛋白和mRNA水平下降与正常孕妇比较有显著性差异p＜0.05提示在PIH发病过程中Ghrelin可能对VEGF，Flt-1蛋白和mRNA的表达具有下调作用，进而影响胎盘血管网的形成和发育；NO含量与NOS活力水平在PIH孕妇胎盘组织中下降，提示Ghrelin可能通过下调VEGF的表达进一步影响血管舒张因子NO水平下降，进而引起胎盘血管痉挛，血压升高，最终导致PIH的发生。

And they systematically studied the effect of the activate spleen-energy law on digestive and absorptive function, it is confirmed that the activate spleen-energy law have significant regulation effect on the action and secretion of gastrointestinal tract. Recently, we established the juvenile rat model with anorexia by imitating the major cause of children and found that the CCK-8S concentration in hypothalamus and periphery blood of the anorexy model was obviously increased .We also found the appestat that the spontaneous discharge frequency of LHA neurons was decreased and the spontaneous discharge frequency of VMH neurons was increased.

近几年，我们采用病因模拟法成功建立了幼龄大鼠厌食模型并发现该模型下丘脑和外周CCK-8S水平显著增高，食欲中枢——下丘脑外侧区神经元自发放电频率减低和下丘脑腹内侧区神经元自发放电频率增加，临床治疗小儿厌食有可靠疗效的运脾复方不仅可调节外周血中与摄食有关的肽类激素水平，如降低CCK-8S水平，而且能调节下丘脑食欲中枢神经元的自发放电频率。

In better management lawn community Geranium sibiricum, Potentilla anserine and Leymus secalinus are the dominant weeds all the time and Geranium sibiricum is the most dominant weed.The regular pattern of Shannon-Weinor index of turf weeds in three different management lawn communities is that in worse community maximum Shannon-Weinor index appears in spring and fall but in better community is in late-summer and primary-fall.

2There are differences between China's best young football coaches in terms of age, seniority, education, marriage, coaches level, nature of work, the nature of work units, regions, eat. In which older and younger age with higher satisfaction, which is into "U" type ;In seniority, the lower academic qualifications, the higher job satisfaction, showing the antigrowth trend. Level in the coaches, the higher the level on the career identity and career development with lower satisfaction, and other dimensioned showed positive growth. In marriage, unmarried outstanding youth football coaches have higher satisfaction in career identity dimensions. In the nature of the work, the coaches satisfaction is higher, but the degree of salary is lower. Nature in the workplace, the youth football coaches in large-scale enterprises outstanding football club are with higher satisfaction. At the district level, the developed coastal regions are with higher job satisfaction, the old industrial base in the northeast have lower job satisfaction in the work environment and salary degrees. regard to remuneration, salaries in 2000-3000or more than 5000 outstanding young football coaches have higher job satisfaction in the current, but salaries in 3000-4000 or 4000-5000 outstanding football coaches, the job satisfaction is slightly lower三、There is significant positive correlation between job satisfaction and job involvement of China's best young football coaches.
