Objective To detect the expression of FOXM 1 transcription factor in cervical cancer tissues and to evaluate its clini-cal significance .Methods Immunohistochemical staining was employed to detect the expression of both FOXM 1 and Ki-67 in a va-riety of cervical tissues respectively from 38 patients with cervical cancer ,22 with cervical intraepithelial neoplasia (ranging from CINⅠ to CIN Ⅲ) and 17 with normal cervical epithelium .Results Abnormal expression rate of FOXM 1 was respectively 5 .88% , 63 .6% and 92 .1% in normal cervix ,CIN and cervical cancer ;Deregulated FOXM1 expression in cervical cancer tissues was signifi-cantly correlated with patients’ pathological differentiation ,clinical stage ,post-operational recurrence and Ki-67 expression level . Conclusion FOXM1 expression may be correlated with the deregulated proliferation ,malignant progression ,staging and prognosis in cervical cancer .

Objective To study the mechanism of CKLF1-plasmid transfer on the myocardial repair in rat AMI models.Methods Eighteen male SD rats were randomly divided into 3 groups and in each separate group,the rats were injected intramuscalary with plasmid DNA encoding CKLF1 gene(n=6),emptyplasmid(n=6)and saline(n=6)with in vivo electroporation respectively.Rats were subjected to left coronary artery ligation on the 6th day after gene transfer and were killed on the 21st day.The expressions of BrdU/?-actin,Ki67/?-actin were assessed by immunohistochemistry.Results BrdU-positive cells in CKLF1 group were more than those in the saline group and the empty plasmid group(cells/HP)(33.11?2.10 vs.14.16?1.63 & 18.46?2.77,P0.05).Conclusion Intramuscular injection with in vivo electroporation of CKLF1 may cause an enhanced myocardial proliferation of acute myocardial infarction tissue in experimental rat.

There are many practical problems to be solved in 7-year program teaching.The whole teaching thought should be widened further.With practical experiences of diagnostics teaching for 7-year program students for many years,we have summed up the results of 7-year program teaching reform.Appling to the holistic teaching mode reform of diagnostics of 7-year program,we have attained the first step achievements.

The annual Live Interventional Neuroradiology & Neurosurgery Course (LINNC) is one of the most important congresses in the neurosurgery and neuroradiology field. LINNC 2009 was held on May 25th this year and lasted for 3 days. In this article, the authors introduced the main points of the congress The congress mainly discussed some hot topics at present time, including both the clinical and fundamental studies of cerebral arteriovenous malformation. Ischemic cerebral disease and intracranial aneurysm, etc. Both neurological and neuroradiological case demonstrations related to the topics, and the main course of the congress were altemately performed. Recent advances in imaging technique and clinical application, such as Dyna-CT and Xper-CT, were also presented on the congress.

Cerebral vasospasm is the main reasons of cerebral infarction and delayed ischemic neurological deficit in patients with spontaneous subarachnoid hemorrhage. At present, the research of cerebral vasospasm is relatively focused on the spasmogens in bloody cerebro-spinal fluid. This article reviews the mechanisms of cerebral vasospasm induced by the major spasmogens in the bloody cerebrospinal fluid after subarachnoid hemorrhage.

Finite element analysis can be used to study the change of the structure and the interior field intensity of human and animal body organs and tissues with simulation experiment. We in our research used finite element analysis software to analyze and solve the spinal cord surface potential problems, and investigated the transmission features of signals generated by interneurons in spinal nerves which were related with body motion control and sensory processing. A three dimensional model of electrical source in rat spinal cord was built, and the influence on potential distribution on spinal cord surface caused by position changes of electrical source in transverse direction and dorsoventral direction were analyzed and calculated. We obtained the potential distribution curves of spinal cord surface and found that the potential distribution on spinal cord surface showed monotone. In addition, potentials of some registration points were smaller than that of registration points around.
