International League Against Epilepsy announced the new International Classification of Epilepsy in 2001. One of the main objectives of the project is to adopt standard terms to describe seizure phenomena according to the terminological database. The project may profit academic communication and resource integration, and provide evidence for the individual treatment for epilepsy. Treatment based on syndrome differentiation is one of the characteristics of the treatment for epilepsy in traditional Chinese medicine (TCM). As far as the individuation on diagnosis and treatment is concerned, TCM and Western medicine present to reach the same goal by different routes gradually for the treatment of epilepsy. But for TCM, the diagnosis and treatment criteria for epilepsy are imperfect and the experts, opinions are not unified, so that the treatment based on syndrome differentiation becomes confused, hence the credit of treatment based on TCM is restricted accordingly. It is necessary to formulate advanced diagnosis and treatment criteria for syndromes of epilepsy in TCM.

0.05).②The animal experiment showed ,in contrast to the control , embryonate rats’ rhodocyte SOD were significantly different after 2 days but no difference before prenatal. ③in contrast with the control , SOD of placenta were significantly different only after 9 days. Conclusions Diagnostic ultrasound in early pregnancy can make SOD change ,but the changes can be reparable.

AIM: To construct pcDNA3.1+/MAGE-3 DNA vaccine and investigate the antigen-specific antitumor immune responses induced by pcDNA3.1+/MAGE-3 DNA vaccine in vivo. METHODS: C57BL/6 mice challenged with B16/MAGE-3 cells were immunized by intramuscular injection of pcDNA3.1+/MAGE-3 DNA vaccine every 10 days. pcDNA3.1+ plasmid and PBS were used as controls. After three cycles of immunization, murine splenic lymphocytes, serum, and tumor were obtained for cytotoxity assay, detections of cytokines (IL-2 and IFN-?), measurement of MAGE-3 antibody, and tumor inhibitory rates, respectively. RESULTS: The pcDNA3.1+/MAGE-3 DNA vaccine immunized murine lymphocytes induced specific cytotoxicity against B16/MAGE-3 cells. Significantly increased secretions of IL-2 and IFN-? were detected. The titres of antibody against MAGE-3 were 1∶1 and 1∶20, while controls were negative. The tumor inhibitory rate in pcDNA3.1+/MAGE-3 group was significantly different from that in controls. CONCLUSION: The pcDNA3.1+/MAGE-3 DNA vaccine was constructed successfully. pcDNA3.1+/MAGE-3 DNA vaccine activates both cellular and humoral immune responses, and induces antigen-specific antitumor immune responses in vivo.

AIM: To investigate the expression of drug resistance genes, MDR1 and MRP, in patients with primary breast cancer after neoadjuvant chemotherapy. METHODS: MDR1 and MRP gene expression were detected by semi-quantitative RT-PCR in 20 patients with primary breast cancer before and after chemotherapy. RESULTS: Before chemotherapy, MDR1 and MRP expression could be detected in 15 cases (75%) and 18 cases (90%), respectively. After chemotherapy, expression of MDR1 was not significantly different from that before chemotherapy, but expression of MRP was significantly different from that before chemotherapy. CONCLUSION: Drug resistance gene MRP, but not MDR1 expression is enhanced in patients with primary breast cancer subjected to neoadjuvant chemotherapy.

Objective To investigate the vascular architecture of subdermal vascular network in antebrachial region, and provide anatomic basis for designing the subdermal vascular network skin flap in the antebrachial region. Methods Anatomical observation and measurement of the blood supply, arterial architecture and venous return of the subdermal vascular network skin flap in anterior antebrachial region were performed on 8 fresh adult specimens perfused with latex and black ink. Results It was found that 4～15 or more fine perforators derived from each the terminal end of the brachial artery and radial or ulnar arteries in anterior antebrachial region, and their diameters were between 0.2～0.9 mm. The anatomical studies showed that the fasciocutaneous perforators supplying the in anterior antebrachial region were found to form rich "spider nevus"arterial networks on the subdermal layer. Moreover, the subdermal vascular networks were also found to give off fine arterial branches into papillary and superficial fascia layers, respectively, to form papillary vascular plexus and superficial fascia vascular network, and all of the vascular networks were anastomosed densely each other. The subdermal venous networks were also anastomosized in plexus and drained into the deep vein. Conclusion Either a random or an axial subdermal vascular network skin flap of the anterior arm can be designed according to the need of recipient defect, and the latter may also be designed as a transfer or a free subdermal vascular network skin flap according to the size of the arterial diameter in the pedicle of skin flap.

AIM: To investigate the expression of angiopoietin-Ⅱ(Ang-Ⅱ)in primary gastric cancer and the pathological factors that influences it. METHODS: Expression of Ang-Ⅱ and VEGF were studied in 72 primary gastric cancer and adjacent normal tissue by reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. RESULTS: The significant difference of Ang-Ⅱ expression between primary tumor and adjacent normal tissue samples was observed. The correlationship between Ang-Ⅱ and VEGF expression in tumors was statistically significant. The expression of Ang-Ⅱ was related to tumor stage and vascular involvement. CONCLUSION: The results manifested that Ang-Ⅱ may play a role in regulating tumor angiogenesis.

This paper points out the importance of intravenous thrombolysis with recombinant tissue plasminogen activator(r-tPA)according to the international guidelines in acute ischemic stroke.Some practical problems,such as the lower rate of thrombolysis for ischemic stroke,the price of r-tPA being too expensive to clinical using,the dosage of r-tPA in Chinese being not clear,the curative effect being not so good,and traditional Chinese medicine (TCM) applied in intravenous thrombolysis,and so on,should be further discussed.
