Objective To study the CT findings and diagnostic role in morning glory syndrome (MGS). Methods CT study of 7 patients with MGS diagnosed by clinical information was reviewed retrospectively. Results CT findings included: (1) the crater like excavation of the disc in 3 patients; (2) the funnel shaped widening of the retrobulbar optic nerve, a pear shaped deformity of the globe in 2 patients; (3) two patients with cystic expansion of the optic nerve, which was of water density and was continuous with the vitreous humor. Conclusion The CT findings of MGS were particularly striking. CT is the imaging method of choice in the diagnosis of this disorder.

OBJECTIVETo investigate the protective effect of mailuoning (MLN) on nerve cells after cerebral infarction induced by photochemistry.

METHODSEighty SD rats were divided into three groups, the control group (n = 20), the model group (n = 30) and the MLN group (n = 30). Focal cerebro-ischemia induced by photothrombosis in adult rat was used as a model. Changes of C-Fos protein expression before and after MLN treatment were observed using immunohistochemistry, computerized imaging technique and transmission electron microscopy (TEM).

RESULTSC-Fos positive cells located in the transitional zone between the necrotic core and normal cortex. C-Fos protein expression began to show 3 hrs after cerebral infarction, peaked at 6 hrs. As compared with the model group, C-Fos expression was significantly reduced in the MLN group (P<0.01).

CONCLUSIONMLN could markedly reduce the injury of nerve cell in the transitional zone, the protection may be related with its inhibition on C-Fos protein expression.

Objective: To study the apoptosis mechanism of microwave ablation (MA) in tongue cancer Cal-27 cell transplanted tumor in nude mice. Methods: 20 nude mice with Cal-27 cell subcutaneously transplanted tumor were randomly divided into blank control group, 50 ℃ 1 min MA group, 50 ℃ 2 min MA group and 55 ℃ 2 min MA group (n = 5) respecitvely, and were treated with MA with indiated perameters respectively. The apoptosis of tumor cells was observed by HE staining. The expression of Caspase-3 and PCNA protein was detected by immunohistochemical SP method. Results: HE staining showed that microwave ablation induced apoptosis of the tumor cells. Immunohistochemical results showed that the expression of Caspase-3 protein was significantly up-regulated in the microwave ablation groups compared with the control group (P ＜ 0. 05), and the expression of PCNA protein was significantly decreased (P ＜ 0. 05) . In microwave ablation 55 ℃ 2 min group, the expression of Caspase-3 protein was increased more (P ＜0. 01), and the expression of PCNA protein was decreased more (P ＜ 0. 01) . Conclusion: Microwave ablation may inhibite the proliferation of tongue cancer cells by inducing apoptosis of the cells. The mechanism may be related to the up-regulation of Caspase-3 signaling pathway and down-regulation of PCNA signaling pathway.
