The nucleotide composition and the phylogenetic relationship among 14 species in Coreidae based on 412bp sequences of Cyt b gene were studied. The results showed: the average contents of T, C, A and G were 34.2 %、11.4 %、35.7 % and 18.7 %, respectively; The content of A+T (69.9 %) was obviously higher than that of G+C (30.1 %), and come up to 82.8% at the third position of codon.

以线粒体细胞色素b基因作为分子标记，首次对缘蝽科4亚科14种昆虫进行序列测定，获得Cytb基因412bp的序列片段，该片段中碱基T、C、A、G的平均含量分别为34.2%、11.4%、35.7 %和18.7 %，A+T平均含量为69.9 %，明显高于G+C含量（30.1 %）。

Methods Twenty patients with diffuse crescentic IgA nephropathy including 13 men and 7 women with mean age of 28.5 and average disease duration of 5.1 months were studied.

选择新月体IgA肾病 2 0例，男性 13例，女性 7例，平均发病年龄为 2 8 5± 12 6岁，平均病程为 5 1± 5 3个月；占IgA肾病 3 1%及新月体肾炎 16 4%；并与总体IgA肾病患者的临床及免疫病理进行比较。

In ACC, NGF,TrkA and p75 mainly existed in cells of duct-like, cribriform and mass-like structures.According to the optical density scanning of immunohistochemistric stain of NGF and TrkA in salivary gland and tumor tissues and quantification analysis, it was shown that the average optical density of NGF and TrkA increased in order of salivary gland tissues around neoplasm, mucoepidermiod carcinoma, and adenoid cystic carcinoma.

2叫 吉林大学硕士学位论文通过对NGF和TrkA在涎腺组织和涎腺肿瘤中的免疫组织化学染色结果进行光密度扫描，对所测平均光密度定量分析，结果显示：NGF和TrkA平均光密度值按照肿瘤周围涎腺组织、豁液表皮样癌和腺样囊性癌依次升高，统计学分析在各组间均有极显著差异(P.01)，表明NGF和TrkA通过自分泌机制调控涎腺腺样囊性癌和豁液表皮样癌的生长与增殖，通过旁分泌机制参与涎腺腺样囊性癌向神经周围的浸润。

Results There were 9 kinds of rodents at Yanshan Mountain, including Rattus confucianus, Apodemus peninsulae, Apodemus agrarius, Mus musculus, Clethrionomys rufocanus, Rattus norvegicus, and Cricetulus triton, Soriculus hypsibius, Crocidura gmelini. The rodent density ranged from 3.13% to 7.33%, and average density was 5.83%.

结果 北京市东北部燕山山脉共捕获社鼠、大林姬鼠、黑线姬鼠、小家鼠、棕背、褐家鼠、大仓鼠、川西长尾鼩、北小麝鼩9种；不同生境地区小兽密度为3.13%~7.33%，平均5.83%；平均带病毒率为2.83%，抗体阳性率为3.77%。

The differentiation of mean differentcoefficient between'individuals among subpopulation'and'individuals between everytwo subpopulation'showed that Castanopsis chinensis was high;and Schima superbaand Cryptocarya chinensis were relatively low.

锥栗亚种群内个体和亚种群间个体的平均相异系数相差最大，亚种群内个体和亚种群间个体的平均相似系数相差也最大；荷木和厚壳桂两者之间的差异小。

From the relationship between two subpopulations,the mean differentcoefficient,mean similar coefficient,Nei'genetic distance and AMOVA results were27.965;0.674;0.062;0.105 for Cryptocarya chinensis.

从两两亚种群间关系看，针阔叶混交林亚种群-常绿阔叶林亚种群之间的平均相异系数分别是27.965；平均相似系数分别是0.674；Nei遗传距离分别是0.062；AMOVA分析中的ΦST分别为0.105。

The results showed that the human disturbance didn't change the dominant positions and roles of Pinus massoniana and Cunninghamia lanceolata in arbor. But it decreased the average diameter at breast height and average tree height and changed the species composition.

结果表明，人为干扰对乔木层马尾松Pinus massoniana和杉木Cunninghamia lanceolata优势种的主体地位和作用没有根本性的改变，但使群落平均胸径和平均树高降低，群落种类组成发生变化。
