幼年

It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

ABSTRACT:On the basis of the data of over 2500 individual cases of homosexuals and their family backgrounds and taking the social investigation of 254 case of homosexuality cured by Nanjing Cerebropathy Hospital from 1987—1993,the preliminary analysis and study of the stages of growth during childhood of homosexuality in Shanghai and other places organized by Liu Dalin and other related studies by other scholors of our country for reference,the author has put forward that durmg the growth of childhood,bad environments,family backgrounds and the mistakes of sex education at early stage are the most important reason of forming homosexuality.

提要，作者基于南京脑科医院自1987～1993年接诊的同性恋2500余人的个案资料，对同性恋者幼年的成长过程和家庭背景进行了初步分析和研究，并参考刘达临组织的上海等地254例同性恋社会调查情况及国内其他学者的有关研究，提出幼年成长环境、不良的家庭背景和早期性教育的失误是我国同性恋形成的最重要的原因。

The results showed that taurine has no significant influence on testis index, epididymis index, spermaduct index, penis index and testis tectology of baby and young rats, but can make old rat testis tectology better, prevent convoluted seminiferous tubule degeneration, germ cell distortion and leydig cell atrophy. Taurine increase the level of T, E2 and LH in baby rat obviously, but has no significant effect on the level of FSH. The level of T and LH was obviously increased by taurine in young and old rats, but the level of E2 and FSH has no significant changes.

结果证明：牛磺酸对幼年、青年、老年大鼠睾丸指数、附睾指数、输精管指数和阴茎指数没有明显影响；对幼年、青年大鼠睾丸组织形态没有影响，但可明显改善老年大鼠睾丸组织形态，阻止曲细精管退化、生殖细胞变形和间质细胞萎缩；显著促进幼年大鼠 T 、 E2、 LH 分泌，而对 FSH 没有明显影响；明显促进青年和老年大鼠 T 和 LH 分泌，而对 E2和 FSH 没有明显影响。

Prehypertensive subjects versus normotensive subjects had significantly higher body mass index and subscapular skinfold, systolic and diastolic blood pressures, and triglycerides beginning in childhood; higher glucose in adolescence; and higher low-density lipoprotein cholesterol, fasting insulin, and insulin resistance index in adulthood. Hypertensive subjects versus normotensive subjects had higher adiposity measures, SBP and DBP, glucose, and triglycerides beginning in childhood; higher insulin and insulin resistant index in childhood and adulthood; and lower high-density lipoprotein, cholesterol in adulthood.

与正常血压者相比，高血压前期者其幼年期基础体重指数、肩胛下皮肤皱褶厚度、收缩压和舒张压、甘油三脂等指标更高；在青春期血糖水平更高；在成年期低密度脂蛋白胆固醇、空腹胰岛素、胰岛素抵抗指数更高；与正常血压者相比，高血压者在幼年时基础水平的肥胖积分、SBP 和DBP、血糖、甘油三脂等更高；在幼年期和成年期胰岛素和胰岛素抵抗指数水平均更高；在成年期高密度脂蛋白胆固醇水平更低。

RESULTS: FGFR1-positive chondrocytes were abundant in the maturative layer and hypertrophic layer, but only few FGFR1-positive chondrocytes were found in the proliferative layer. In the control group, the expression of FGFR1 increased from 6-week-old to 10-week-old rats, and then decreased and went stable. In both young and adult group, the expression of FGFR1 in the experimental group was significantly lower at 4, 6 weeks and higher at 8 weeks than that in the control group, especially in the young group (P.05). But no difference was found between the experimental group and the control group at 2 weeks in both groups. CONCLUSION: FGFR1 may play an important role in the remodling of condylar cartilage induced by occlusal disorders.

结果：FGFR1主要表达在大鼠髁突软骨过渡层和肥大层，增殖层很少；正常组大鼠髁突软骨从6周龄到10周龄FGFR1表达逐渐增强，10周龄后降低，并保持在一个稳定水平；成年组和幼年组实验4、6周时FGFR1的表达均显著低于对照组，实验8周时的表达高于对照组(P.05)，幼年组尤为明显，实验2周组与对照组无显著差异。

The heart rate of narcose infant rats is slower compared with that of adult rats, which might he referable to the sensitivity of infant rats to the anaesthetic.

麻醉的幼年鼠心率比成年鼠慢，可能与幼年鼠对麻醉药敏感有关。

In rat,no matter the young or old,there is only endotheliumin the tunica intima,there are no subendothelial layer and internal elastic membranes.

而在大鼠冠脉不论幼年或老年，其内膜仅由内皮构成，无内弹性膜和内皮下层，因而从幼年至老年始终没有内膜增厚和管腔变窄现象。

In aged,the internal and external elastic membranes both disappeared,the subendothelial layer is evidently thickened,in which there are some smallblood vessels and local calcification can be seen occasionally.
