Cattle dung, firewood, and crop straw have being used as survival necessities by farmers and herdsmen for thousands of years in Tibet. Until recently such biotic energy source still constitutes more than 92 per cent of total rural energy consumption due to lack of petroleum, coal and new alternative energy sources. As a result, environmental degradation such as land desertification, soil erosion, grassland degradation and soil fertility reduction is increasingly aggravated, the area of desertified land has increased 1467.5 km2 from 1991 to 1997. Degraded area of grassland has reached 2.60×107hm2, increased by 116.1% from 1987 to 1996. To prevent further deterioration of eco-environment in Tibet great efforts should be made to make full use of ample solar energy, wind energy and other biotic energy of the Qinghai-Tibet Plateau. The solar cooking stoves and solar hothouse, expand forest area and replace existing abiotic energy sources with firewood forest should be popularized. This is an urgent task to protect the eco-environment of Tibet today.

Objective： Cerebrospinal fluid （CSF） rhinorrhea may be a serious complication after neurosurgery. Some of them can be treated conservatively by continuous CSF drainage with a lumbar subarachnoid catheter. On the other hand, spinal puncture may result in headache by CSF leakage. Methods： Present a 17-year-old female who suffered from CSF rhinorrhea after pituitary surgery was treated by making use of spinal puncture after failed catheter drainage. Results： The patient was successfully treated by this way. Conclusion： Spinal puncture by 16-gauge Touhy needle seems to be a possible way to substitute the traditional continuous lumbar subarachnoid catheter to drain the CSF in patients with rhinorrhea.

The main aim of this paper is to establish several new criteria on the attractor for the solutions of neutral stochastic func- tional differential equations. A kind of ψ-function is introduced to our discussion, and some results on the attractor for the product of the ψ-function and the solutions are obtained. As a byproduct, a number of new criteria on asymptotic stability are also shown.

Meningioma-glioma mixed tumor is rare central nervous system tumor. It is necessary to study its clinical and pathological characteristics as well as its possible genesis. This case was a 54-year-old man who was readmitted for recurrent glioma. Magnetic resonance imaging showed a big mass in right temporal lobe which was confirmed as meningioma-glioma by immunohistochemical analysis. Specific immunohistochemical staining is significant in tumor differential diagnosis, and helps to confirm tumor histic origin. By pathological studies, we found that glioma could stimulate adjacent normal meninges into neoplastic proliferation.

Acta Geologica Sinica(English Edition) 1987年第2期 61-76+111页

In the Zhongtiao Mountains, all of the most significant copper deposits occur in the early Proterozoic mobile belt. They are the meta-sedimentary copper deposit in meta-pelite semi-pelite formation and the meta-volcanic porphyry copper deposit in meta-potassic volcano-sedimentary formation, belonging respectively to the lower and middle-upper Jiang-xian Group(2, 500--2, 300 Ma); and the meta-sedimentary-remoulded copper deposit in metacarbonate-black shale formation of the Zhongtiao Group(2, 300--1, 830 Ma). The Zhongtiao Movement(about 1, 800 Ma B. P.) had caused regional metamorphism and hydrothermal action added to the early Proterozoic mobile belt, thus reformedthe original ore deposits of different genetic types to give similar hydrothermal and geochemical characters. However, primary features of the ore deposits as controlled by the original sedimentary or volcano-sedimentary formation are basically unaltered.

作者： Gu Xiangjin Xu Jin Ma Banyou Chen Gong Gu Peiyuan Wei Dong hu weixing Department of Neurosurgery Jiangning Hospital Affili- ated to Nanjing Medical University Nanjing 211100 China Department of Neurosurgery the First Affiliated Hospi- tal of Nanjing Medical University Nanjing 210029 China

Objective： To investigate the neuropro- tective effects of glycyrrhizin （Gly） as well as its effect on expression of high-mobility group box 1 （HMGB1） in rats after traumatic brain injury （TBI）. Methods： Male Sprague-Dawley rats were randomly divided into three groups： sham group, TBI group, and TBI＋Gly group （n=36 per group）. Rat TBI model was made by using the modified Feeney＇s method. In TBI＋Gly group, Gly was administered intravenously at a dosage of l0 mg/kg 30 min after TBI. At 24 h after TBI, motor function and brain water content were evaluated. Meanwhile, HMGB 1/HMGB 1 receptors including toll-like receptor 4 （TLR4） and receptor for advanced glycation end products （RAGE）/nuclear fac- tor-κ B（NF- κ B） signaling pathway and inflammatory cytokines in the injured brain tissues were detected using quantitative real-time polymerase chain reaction, western blot, electrophoretic mobility shift assay and enzyme-linked immunosorbent assay. Furthermore, HMGB l, RAGE and TLR4 immunohistochemistry and apoptosis were analyzed. Results： Beam walking performance impairment and brain edema were significantly reduced in TBI＋Gly group compared with TBI group; meanwhile, the over-expressions of HMGB 1PHMGB 1 receptors （TLR4 and RAGE）/NF- κB DNA-binding activity and inflammatory cytokines were inhibited. The percentages of HMGB 1, RAGE and TLR4- positive cells and apoptotic cells were respectively 58.37%±5.06%, 54.15%±4.65%, 65.50%± 4.83%, 52.02%±4.63% in TBI group and 39.99%±4.99%, 34.87%±5.02%, 43.33%±4.54%, 37.84%±5.16% in TBI＋Gly group （all P〈0.01 compared with TBI group）. Conclusion： Gly can reduce secondary brain injury and improve outcomes in rat following TBI by down-regula- tion of HMGB 1/HMGB 1 receptors （TLR4 and RAGE）/NF- κB - mediated inflammatory responses in the injured rat brain.
