大学生心理素质与思想品德发展的关系

研究大学生心理素质与思想品德发展的关系，目的在于分析、发现个体在接受教育过程中的心理运动规律，从而提高思想教育的实效性。本文从马克思主义认识论和实践论的观点出发，依据教育心理学的原理，探讨了心理健康教育与思想品德教育的内在联系和相互作用，提出良好的心理素质是大学生思想品德发展的基础的观点。认为品德的形成与人的心理活动息息相关，个体如果没有良好的品德，将影响其心理素质的完善；同样，没有健全的心理素质，思想品德也不能得到很好的发展。只有思想品德教育与心理健康教育协调发展，共同作用，才能收到良好的教育效果。     

Policy determinants affecting the hunger millennium development goal

The possible effect of Government Consumption (a component of Gross Domestic Product (GDP)) on attainment of the hunger Millennium Development Goal (MDG1) was analyzed by evaluating the effect of macroeconomic, social, demographic and policy variables on average undernourished population. Eighty-four developing countries with data available on undernourished population were included in an ecological study. Regression models were applied to explore possible determinants of Undernourished between 1990 and 2004 and consequent achievement of the projected 2004 MDG1. In 2004, 1.4% of the overall undernourished population in the studied countries [70.16 million people] was in excess of the projected level required to meet MDG1. The multiple linear regression showed significant associations between Undernourished and poverty levels, the Gini Index, rural population and Government Consumption. The multiple logistic regression showed significant associations between achievement of projected 2004 MDG1 levels and Government Consumption and the Gini Index. The significant associations between Undernourished and Government Consumption suggest that the effects of GDP components on social conditions call for more thorough research and that policymakers such as governments and international financial institutions need to ensure that changes in distributive and redistributive policies do not negatively affect the possibility of achieving MDG1.

略述中医刺血术发展史

刺血术是中医学中一种古老而独特的针刺治疗方法，文章对刺血术的发展进行了概述，并对其历史分期进行了总结。刺血术发展的四个历史阶段是：第一阶段为起源及萌芽阶段(春秋以前)，以砭石的出现及其应用标志；第二阶段为理论奠基及经验积累阶段(战国至唐)，以《黄帝内经》的问世为其理论体系形成标志；第三阶段为理论创新及特色形成阶段(宋金元)，以金元四大家刘完素、张从正、李杲、朱震亨的刺血成就为其代表；第四阶段为不断完善及日趋成熟阶段(明清)，以诸医家对瘟毒疫疠的刺血经验为其特征。     

Targeting access to reproductive health: giving contraception more prominence and using indicators to monitor progress

Unmet need for contraception represents a major failure in the provision of reproductive health services and reflects the extent of access to services for spacing and limiting births, which are also affected by personal, partner, community and health system factors. In the context of the Millennium Development Goals, family planning has been given insufficient attention compared to maternal health and the control of sexually transmitted infections. As this omission is being redressed, efforts should be directed towards ensuring that an indicator of unmet need is used as a measure of access to services. The availability of data on unmet need must also be increased to enable national comparisons and facilitate resource mobilisation. Unmet need is a vital component in monitoring the proportion of women able to space and limit births. Unmet need for contraception is a measure conditioned by people's preferences and choices and therefore firmly introduces a rights perspective into development discourse and serves as an important instrument to improve the sensitivity of policy dialogue. The new reproductive health target and the opportunity it offers to give appropriate attention to unmet need for contraception will allow the entry of other considerations vital to ensuring universal access to reproductive health.

国人胎儿胸腺的生长发育

称量了14—38周共56例引产胎儿胸腺的重量并观察了6—38周共25例引产胎儿胸腺的组织结构,认为胸腺在胚胎时期生长速度较快。光镜观察,6周已出现胸腺的始基,第9周开始出现淋巴细胞,12周开始分叶,13周以后,皮质髓质渐趋分明并出现胸腺小体,15周后胸腺小叶增多变宽,新小叶形成旺盛,胸腺小体增多,至28周后结构已近似成熟。     

Early organization of the pituitary gland in Sparus aurata L. (Teleostei) An ultrastructural study

The cell organization of the pituitary gland and the relationship between neurohypophysis and adenohypophysis in the early developmental stages of the gilthead sea bream, Sparus aurata, were studied by electron microscopy. In newly hatched larvae, the pituitary gland was embedded in the ventral floor of the diencephalon and separated from the hypothalamus by a continuous basal lamina. Elongated mesenchymal cells next to the ventral surface were observed. At this stage, there was no neurohypophysis and the adenohypophysis consisted of undifferentiated endocrine cells with small scarce secretory granules and a few stellate cells, with no distinctive zonation. An incipient neurohypophysis was present in 1-day-old larvae. The first evagination of the neurohypophysis into the adenohypophysis were observed in 2-day-old larvae and developed progressively with age, being deeper in the caudal zone. Two regions in the adenohypophysis, one anterior — the presumptive pars distalis — and one posterior — the presumptive pars intermedia — were found in 2-day-old larvae. Three regions (rostral and proximal pars distalis and pars intermedia) were clearly distinguishable in 4-day-old larvae. The ultrastructural features of the pituitary endocrine cells varied during gland differentiation, with the secretory granules gradually increasing in number and size, accompanying organelle development. Nevertheless, even in the oldest larvae studied (65 days), undifferentiated cells similar to those in the earliest stages were observed. The first blood vessels appeared in the neurohypophysis around 16 days after hatching. During early development, the pituitary gland progressively emerged from the ventral floor of the brain. By 16 days, the principal pattern of the pituitary gland architecture appeared to be established.     

Cellular distribution of the new growth factor Pleiotrophin (HB-GAM) mRNA in developing and adult rat tissues

Summary Pleiotrophin (PTN), also known as HBGAM, belongs to an emerging cytokine family unrelated to other growth factors. We report here the first comprehensive study using in situ hybridization on the cellular distribution of this new heparin-binding growth factor mRNA in rat tissues. PTN mRNA was developmentally expressed in many — but not all — neuroectodermal and mesodermal lineages, whilst no PTN mRNA was detected in endoderm, ectoderm and trophoblast. PTN mRNA was found in the nervous system throughout development, with a post-natal peak of expression. In the adult nervous system, significant expression persisted in hippocampal CA1 pyramidal neurons and in cortical neurons, but also in different non-neuronal cells types in various locations (olfactory nerve, cerebellar astrocytes, pituicytes, Schwann cells surrounding the neurons in sensory ganglia). PTN mRNA was also found during development in the mesenchyme of lung, gut, kidney and reproductive tract, in bone and cartilage progenitors, in dental pulp, in myoblasts, and in several other sites. Expression was differently regulated in each location, but usually faded around birth. In the adult, PTN mRNA was still present in the meninges, the iris, the Leydig cells of the testis and in the uterus. PTN mRNA was also strongly expressed in the basal layers of the tongue epithelium, which is the only epithelium and ectodermal derivative to express PTN mRNA, and this only after birth. PTN is known to be a growth factor for perinatal brain neurons and a mitogen for fibroblasts in vitro. Recently, trophic effects on epithelial cells and a role as a tumour growth factor have been reported. The mechanisms of regulation and the functions of PTN are however still uncertain. Its expression pattern during development suggests important roles in growth and differentiation. Moreover, the presence of PTN mRNA in several adult tissues and the up-regulation of PTN mRNA expression in the gravid uterus indicate that PTN also has physiological functions during adulthood.
