普遍认为变暖有利于高山植被生态系统,并已经导致冰缘植物向高海拔的扩张.珠峰山谷金字塔气象站(海拔5050 m)1994~2018的气象记录显示,高海拔山区呈显著的暖干化趋势.然而,我们依然不清楚暖干化是否对冰缘植被更新和分布造成显著影响?本研究在喜马拉雅山中段3个山谷建立了8块(30 m×120 m)滇藏方枝柏(Juniperus indica)和高山柏(Juniperus squamata)灌木线样地(海拔介于4344~5074 m之间).样地调查揭示,自20世纪90年代之前所有样地种群更新呈增加的趋势,然而90年代以来更新持续下降.种群更新与春季、夏季温度之间呈现显著的负相关关系,暗示了暖干化加剧了水分胁迫,并限制了种群的更新.另外,近60年来所有灌木线位置稳定.近30年遥感数据也证实,研究区冰缘植被无变绿趋势,甚至出现2%-6%的植被生长减弱现象.因此,进一步研究应该探讨冰缘植被生长减弱对喜马拉雅山区水循环和生物多样性的影响.

11岁女童肠系膜淋巴管肌瘤的保守治疗及其长期随访1例

世界核心医学期刊文摘（儿科学分册） 2005年第9期1卷 28-28页

The authors report the case of a 11-year-old girl admitted for a mesenteric tumor discovered during an appendicectomy. The abdominal D ppler echography and computed tomography (CT) scan showed a 8 × 6 × 7cm multinodular mass involved in the mesenterium. Biological markers and iodine 131 meta-iodobenzylguanidine (MIBG) scintigraphy results were normal. Percutaneous biopsies were performed. Pathology results showed perilymphatic proliferation of smooth muscle cells leading to cystic lesions. No sign of malignancy was seen. Laparotomy showed a multinodular fixed mass involved from the root of themesenterium. The superior mesenteric vessels were encircled by the tumor, which could not be resected completely. Partial resection was performed. The pathology and the immunohistochemical tests confirmed the diagnosis of lymphangiomyomatosis. At 21 years of age, she remains asymptomatic. An echography and CT scan showed the mass remaining unchanged in size and echopattern. Lymphangiomyomatosis (LMA) is thought to affect exclusively women in their reproductive life, and the steroid hormones are supposed to play an essential role in the pathology and in the behavior of this condition. Infantile LMA is exceptional. The patient reported is remarkable for her young age, the location of the tumor, her long history, and her benign course. Because the tumor is supposed to be hormone dependent, the surge of oestrogen in this 21-year-old woman may initiate the extensive form of lymphangiomyomatosis with pulmonary involvement, the prognosis of which is extremely poor.

饮食性水中毒:病因预防学

Case report: The authors report the case of an infant presenting with status epilepticus, apneas and hypothermia, related to hyponatremia. The cause was water intoxication, secondary to feeding a dilute formula and free water. The parents were notoriously challenged by the care of their children. Such disorder could have been prevented. Conclusion: Dietary history may be key to the diagnosis of hyponatremia in children. Water intoxication of nutritional origin can be prevented.
