BACKGROUND: S-100 and neuron specific enolase (NSE) possess the characteristics of specific distribution in brain and relative stable content. Some studies suggest that combined detection of the both is of very importance for evaluating the degree of brain injury. OBJECTIVE: To observe the changes of S-100 protein and NSE levels at different time points after acute brain injury, and evaluate the values of combined detection of the both for different injury degrees, pathological changes and prognosis. DESIGN: Case-control observation. SETTING: Department of Neurosurgery, Second Affiliated Hospital, Lanzhou University. PARTICIPANTS: Thirty-four inpatients with brain injury, 19 males and 15 females, aged 15 to 73 years, who received treatment between September 2005 and May 2006 in the Department of Neurosurgery, Second Affiliated Hospital, Lanzhou University, were recruited. The patients were admitted to hospital at 24 hours after brain injury. After admission, skull CT confirmed that they suffered from brain injury. Following Glasgow coma score (GCS) on admission, the patients were assigned into 3 groups: severe group (GCS 3 to 8 points, n =15), moderate group (GCS 9 to 12 points, n =8) and mild group (GCS 13 to 15 points, n =11). Following Glasgow outcome scale (GOS) at 3 months after brain injury, the patients were assigned into good outcome group (GOS 4 to 5 points, good recovery and moderate disability included, n =19) and poor outcome group (GOS 1 to 3 points, severe disability, vegetative state and death, n =15). Ten subjects who received health examination concurrently were chosen as normal control group , including 6 males and 4 females , aged (45.4±14.3)汤(c)years. In our laboratory, the normal level of NSE was ≤15.2 ng/L, and that of S100 was ≤0.105μg/L. METHODS: ①Blood samples of control group were collected when the subjects received health examination. Blood samples of patients with brain injury were collected at 24 hours, 3, 7 and 14 days after injury. Ac

美籍华裔作家汤亭亭以其《女勇士》、《中国佬》等关涉中国题材的作品在美国文坛名声鹊起。汤亭亭的创作过程也是其美国主流身份的建构过程。她的文化身份建构策略是语言层面、身体层面和文化层面的自我东方化。汤亭亭的文化身份需求约束了她创作的视域,局限了她作品的文学性。华裔文学应该摆脱东方主义话语束缚,选择宽泛普适题材,方能真正确立华裔作家在西方社会的文化身份和文学地位。

当代英国作家贾斯汀·希尔的"中国三部曲"中的成名作小说《品梦茶馆》享誉世界,被翻译成十一国文字全球发行,先后获得多种文学奖项。西方评论界因此认为希尔对中国了解深入,谙熟中国社会与文化,把他称为"中国作家"。在西方评论界大加赞誉的同时,中国读者不难发现其小说中存在的各种冲突和矛盾。本文通过对小说主要人物大山和方太太的分析以及对葬礼、古尸等一些荒诞怪异细节的剖析来展现文本中暗含着的中西文化、中西意识形态以及传统文化与现代文化之间的对抗。通过对各种冲突表象的集中分析,探究出《品梦茶馆》中各种冲突的原因可以归结为作者个人文化背景、意识形态的偏见和东方主义影响的残存。

Segmented evolution of Deyang-Anyue erosion rift trough in Sichuan Basin and its significance for oil and gas exploration, SW China

Petroleum Exploration and Development 2022年第2期49卷 313-326页

作者： MA Kui WEN Long zhang Benjian LI Yong ZHONG Jiayi WANG Yunlong PENG Hanlin zhang xihua YAN Wei DING Yi CHEN Xiao Research Institute of Petroleum Exploration and Development PetroChina Southwest Oil and Gas Field CompanyChengdu 610041China Chengdu University of Techonology Chengdu 610059China

Based on analysis of field survey, drilling and seismic data, the formation and evolution process of Deyang-Anyue erosion rift trough in Sichuan Basin was reconstructed, and exploration areas were divided and evaluated. The results show that:(1) Dengying Formation in and around Deyang-Anyue erosion rift trough varies widely in sedimentary characteristics. The Dengying Formation in the northern part of the erosion rift trough developed deep-water sediments, the Dengying Formation in the northern part of the basin varied gradually from basin to slope, platform margin, and restricted platform, and the Dengying Formation in the middle and southern parts of the trough developed carbonate platform facies.(2) Deyang-Anyue erosion rift trough is formed by extensional rift and karst erosion jointly, the north section of the erosion rift trough is mainly the product of tensile rift, while the middle and south sections are formed by erosion in multi-episodes of Tongwan period.(3) Based on the segmented origins of the erosion rift trough, Dengying Formation in and around it is divided into three exploration fields: lithologic mound and beach bodies at the northern platform margin of the basin, karst mound and beach bodies in the central platform, and karst residual mounds in the central southern trough of the basin, among them, the karst residual mounds in the central southern trough of the basin are a new frontier for natural gas exploration in the basin, and the lithologic mound and beach bodies at the northern platform margin are a new position for increasing the reserves of trillions of cubic meters of natural gas resources in the basin.

当代英国作家贾斯汀.希尔的三部中国题材作品《黄河》、《品梦茶馆》和《天堂过客》确立了他在当代英国文坛的地位。作品被译成多国语言文字在西方世界广为流传,但尚无中文译本。希尔借助三部作品分别反映了中国乡村风俗、城镇企业改革和唐朝历史文化,以求全面客观地再现中国社会,驳斥西方对中国的已有偏见。作品很自然真实地体现了希尔对待中国文化从排斥到接受甚至陶醉的跨文化交际过程,承载了跨文化交流的发展趋势,暗示着在全球化语境下异质文化碰撞交流中应该抛开已有典型偏见,以发展动态的眼光来关照他者文化。
