New data of structural styles and geochronometry in the Dulong-Song Chay metamorphic dome indicate at least two epoches of major extensional tectonics: the D, deformation of the rising and exhumation of the dome occurred at 237-228 Ma; and the D2 deformation overprinted and re-deformed on the dome at 86-78 Ma. Of them, the D, deformation shows a consistent forming time, extensional direction and tectonic regime amongst the Dulong-Song Chay dome, South China block and the north margin of the South China Sea basin.

对位于华南地块西南缘的都龙－Song Chay变质穹隆体的研究表明，在中生代至新生代时期，至少经历了2期重要的伸展构造：D1期(237~228 Ma)穹隆的隆升与表露阶段，代表了印支期造山作用前的伸展构造；D2期(86~78 Ma)叠加和改造阶段，并有可能始于176~146 Ma，致使穹隆进一步隆升和表露。D2期构造在发育时间、伸展方向及变形方式等上既与华南地块同时期区域伸展构造特征相一致，也与南海盆地北缘早期扩张特征相一致。

"The capacious upper fornix of the elderly may harbor a coagulum colonized by S. aureus , leading to chronic conjunctivitis that may lead to severe sight impairment due to toxic keratopathy and secondary corneal vascularization," Mr. Rose writes."The giant fornix syndrome should be considered in any elderly patient in whom there is repeated relapse of a purulent conjunctivitis and a chronic toxic keratitis — especially when these relapses occur after successful lacrimal drainage surgery."The author reports no potential financial conflicts of interest.

Mr。 Rose指出，老年人大容量的上穹窿可能隐藏受到金黄色葡萄球菌植入的凝块而导致慢性结膜炎，可能因为毒性角膜病变与继发性角膜血管化，而导致严重视觉受损；任何患有反覆再发性化脓结膜炎及慢性毒性角膜炎，特别是当这些复发发生於成功的泪腺引流手术后的老年病患，都应该评估是否为巨穹窿症候群所致。

As an immunomodulator NO may play a role like a double-edged sword since it expresses both in immuonchalleged and immunosspresed states. 2. After received external stimulus the morphology of ependyma of SFO could be changed and varied with time course, particularly its cellular apoptosis do occur and earlier than the ordinary areas of the brain. 3. Astrocytes in SFO could express cFos protein induced by LPS, suggesting the cells may maintain homeostasis in the brain in a longer period and modulate immune state of the brain. 4. As a CVO, SFO may sense changes of blood-bearing immunosignals earlier and instantly response to them, thus as one of windows of the brain SFO do take part in immunomodulation within the brain.

通过我们的实验结果我们可以得出这样一些初步的结论：1、一氧化氮作为免疫调质参与了机体免疫，它既能在免疫激发状态下又可在免疫抑制状态下进行表达提示，NO在脑内免疫调节中的作用可能是双向的。2、穹窿下器的室管膜形态在接受外界刺激后，随着时间的变化而不同，扫描电镜下的凋亡形态虽需进一步证实，但室管膜细胞确实发生了凋亡，并且穹窿下器发生的较早。3、穹窿下器内的星形胶质细胞在给予大肠杆菌后确实可以表达c-fos蛋白，并可能通过自身的激活来较长时间的维持体液的动态平衡，调节脑内免疫状态。4、穹窿下器作为感受性室周器官之一，能够较早的感受血携免疫信息的改变并及时作出反应，可能作为外周免疫信息进入脑内的窗口之一来参与脑的免疫调节。
