Objective To investigate the clinical and angiographic features in hemorrhagic moyamoya disease patients with the posterior circulation involvement (PCI). Methods The clinical and imaging data of 224 patients with hemorrhagic moyamoya disease from December 2002 to December 2011 were analyzed retrospectively. The patients were divided into either a PCI group (n=57)or a non-PCI group (n=167) according to whether they had PCI or not. Results (1)Suzuki staging concentrated in stageⅤandⅥin the PCI group,accounting for 42. 1%(24/57)and 40. 4%(23/57)respectively;Suzuki staging concentrated in stage Ⅲ and Ⅳ in the non-PCI group,accounting for 31. 1%(52/167)and 41. 9%(70/167)respectively. There was significant difference in the distribution of Suzuki staging between the patients of both groups (P <0. 01). (2)In the PCI group,the thalamic hemorrhage,intraventricular hemorrhage,ganglia hemorrhage,subarachnoid hemorrhage accounted for 43. 9%(26/57),38. 6%(22/57), 3. 5%(2/57),14. 0%(8/57),respectively;There was no cerebral lobe hemorrhage. In the non-PCI group, the thalamic hemorrhage,intraventricular hemorrhage,basal ganglia hemorrhage,subarachnoid hemorrhage and cerebral lobe hemorrhage accounted for 0,37. 7%(63/167),25. 1%(42/167),15. 6%(26/167),21.6 (36/167),respectively. The proportion of hemorrhage types between the PCI group and non-PCI group was significantly different(P<0. 01). (3)The dilation of anterior,posterior choroidal artery ,and patency of posterior communicating artery,posterior pericallosal artery in bleeding side accounting for 19. 3%(11/57),82. 5%(47/57),36. 8%(21/57),78. 9%(45/57)in PCI group and 36. 5%(61/167),3. 0%(5/167),68. 9%(115/167),80. 2%(134/167)in non-PCI group. The ratio of of abnormal vessels between PCI group and non-PCI group had significantly statistical difference (P<0. 01). Conclusion Hemorrhagic moyamoya with PCI is common. Suzuki staging is usually in the advanced stage of vascular staging of moyamoya disease. The thalamic hemorrhage is the main type of bleeding. Posterior choroidal artery rupture may be the main reason of hemorrhage.

Objective: To investigate the proliferation of three subtypes of odontogenic keratocysts(OKC), namely simple(not recurrent),recurrent and basal cell naevus syndrome(BCNS) associated lesions. Methods: Ki 67 expression was studied in 34 odontogenic keratocysts(simple, n =10;recurrent, n =12;syndrome, n =12)by biotin streptavidin method using Ki 67 monoclonal antibody after microwave treatment. Ki 67 positive cells were counted manually and related to the area of epithelial lining as determined by computer image analyzer. Results: Ki 67 positive cells per mm 2 in simple odontogenic keratocysts ①, recurrent odontogenic keratocysts ② and BCNS ③ were 1 812.29?606.47, 2 393.88 ?997.08 and 3 983.17?858.92 respectively(① or ② vs ③ P 0.05). Conclusion: The basal cell naevus syndrome associated OKC has a higher rate of epithelial proliferation than non syndrome OKC, the increased epithelial proliferation is correlated with increased recurrence potential. Ki 67 may be an alternative method to differentiate syndrome and non syndrome OKC.

Acute myocardial infarction (AMI) is caused by acute occlusion of the coronary artery. The partial necrosis of the myocardium is caused by severe and prolonged ischemia,which is characterized by persistent and severe chest pain, the high mortality rate. Fast recovery can be achieved the coronary artery blood circulation by emergency percutaneous coronary intervention (PCI), can improve myocardial is-chemia, save moribund myocardium. The medical profession is generally believed that on the basis of en-suring the safety of patients with AMI, the normal rehabilitation should be carried out as soon as possible. In this article, the domestic in recent years, AMI emergency PCI in early postoperative rehabilitation treatment method, the intensity and evaluation index of three aspects were summarized. The starting time of the early rehabilitation of AMI patients in foreign countries is earlier than our country. As we all know that via radial artery PCI has the smaller puncture and more convenient hemostasis, so there is no doubt that it can pro-vide favorable conditions for recovery of patients. Therefore, it is necessary to expand the research field in order to determine the best rehabilitation opportunity and the most excellent rehabilitation program , so as so determine the best recovery time and the most excellent rehabilitation program in patients with AMI after PCI operation.
