高原地区慢性前列腺炎的中医综合治疗

我院在海拔3658米高原地区采用中医综合疗法治疗慢性前列腺炎取得显著效果。笔者认为：本病的发生是由于“肾虚”而“下焦湿热”、“气化失调”所引起。治疗应以清热利湿、化瘀解毒为主。但因本病的特殊性，一般单一治疗很难达到理想疗效，只有采用中医内外综合治疗，方能达到最佳疗效。

西藏高原植物区系中特有属的研究

The Xizang (Tibetan) flora with numerous endemics is of importance in Chi- nese flora.   According to recent statistics there are in Xizang 27 genera of  spermatophytes endemic to China, being only 2.25% percent of the total number of genera in the Xizang flora. Four of them are regarded as palaeoendemics (14.81%) and the others as neoendemics (85.19%). These endemic genera, of 30 species and 3 varieties, belong to 17 families, of which, Umbelli- ferae contains 6 genera, 7 species and 3 varieties; Compositae has 6 genera and 7 species, and Gentianaceae 1 genus and 2 species.  All the other families each comprises one genus with a single species.       The cosmopolitan families together comprising 14 genera with 15 species have the highest perecentage (52.92%) and the tropical ones (5 families, 5 genera with 5 species) come to the next (29.42%), followed by the temperate ones (3 families, 10 genera with 10 species) (17.66%). It shows that these endemic genera are obviously related to the tropical flora and temperate one in essence.        According to the number of species, the genera endemic to China and occurring in Xi- zang flora may be grouped as fallows. Monotypic endemic ones 14 (51.85%) Ditypic endemic ones 6 (22.22%) Oligotypic endemic ones 4 (14.81%) Small endemic ones 3 (11.11%)        The formation of the endemic genera is correlated with the topography, climate and en- vironmental conditions, and they may have resulted from the diversification in geography and climatic influence for a long time.  The southeastern part of Xizang Plateau is of very diverse ecological conditions, with the adequate precipitation, which may explain the concentration of these endemic genera in this region.        The largest similarity coefficient (38.30%) of the genera endemic to China and occurring in Xizang is with those in Qinghai Plateau, next, with those in Yunnan and in Sichuan pro- vinces (both 27.60%), which shows that these endemic genera are related to the floras of the regions mentioned above.        The difference in the horizontal distribution of these endemic genera is obviously between the southern and northern parts of Xizang Plateau.  The vertical distribution of the genera is also rather obvious, from 800 m to 5200 m above sea level, but concentrated in the zone of 3000 m to 4500 mm.  Therefore their occurrence in Xizang is not only affected by the historical environmental conditions but also controlled by the horizontal and vertical distribution.      The origin and evolution of some endemic genera, such as Psammosilene, Parateropyrum, Sphaerotylos, Salweenia, Ajaniopsis, Xizangia, Sinoleontopodium, are discussed in this paper.      Parateropyrum, a monotypic palaeotropic endemic, belongs to the tribe Atraphaxideae in- cluding Atraphaxis, Calligonum and Pteropyrum.  It may be a comparatively advanced group in the tribe, and is closely related to the genus Pteropyrum  which is  distributed in western Asia.  The genus Parapteropyrum has possibly survived as a palaetropic-tertiary  relic in this region.      Sphaerotylos, a member of the subtribe Sphaerotylinae, the tribe Boehmerieae in the family Urticaceae, is a comparatively primitive genus in the tribe Boehmerieae so far known.  As the other subtribes, such as Boehmerinae, Sarconchlamydinae, Orecnidinae and Maoutinae, are dis- tributed in the tropics, rarely in the subtropics, the genus is no doubt a palaetropic -tertiary relic.      Sinoleontopodium, belonging to the tribe lnuleae in Compositae, is also related to the ge- nus Leontopodium.  It is probable that the genus Sinoleontopodium arised later than the other.       We come to the conclusion that the southern part of Xizang Plateau is also one of thecentres of the origin and differentiation of genera endemic to China.     

冰芯气候环境记录研究：从科学到政策

冰芯是过去气候环境变化信息的重要载体。文章着重阐述了三极(南极、北极和第三极)冰芯研究在揭示过去气候变化、大气温室气体含量变化、太阳活动、火山活动及人类活动等方面所取得的成就,并说明冰芯研究对相关环境政策制定(如含铅汽油禁用政策、温室气体减排政策)的推动作用。建议国家尽快建立冰芯档案储藏库,以拯救冰芯资源,为后世科学研究与国家发展服务。

高校职称评定的群体决策行为分析及其规范研究

通过深入分析高校职称评定的全过程，指出职称评定过程中的非正式组织，职称申报人与评审人之间的信息不对称、评审人的机会主义行为和内部人控制等是导致评审过程与结果出现不公正的主要原因，并对高校职称评定过程进行了重新设计。     

国外城市公共图书馆服务体系建设及其启示

纽约、伦敦、东京三大城市公共图书馆服务体系建设在管理模式、资源配置、地域分布等方面表现出国外城市公共图书馆服务体系建设的特点。新时期我国城市公共图书馆服务体系建设应该借鉴国外的有益经验,在推行总分馆制、合理规划公共图书馆服务网点、完善城市图书馆资源配置及管理方式、增强公共图书馆分馆设置和服务效果等方面继续努力。
