The theory of planned behavior is used to study physician's behavior of clinical pathway compliance,on which the model of decision making mechanism for such compliance was built.This aims at exploring the relationship between the behavioral risk factors,behavioral belief and behavioral intention, and the occurrence,and recommend on further regulation of physicians'behavior and policies in hospital management.

By searching relevant data from the PubMed database, Chinese National Knowledge Infrastructure (CNKI) database and Wanfang database, a comprehensive analysis and review regarding acupuncture for cerebral ischemia reperfusion injury (CIRI) in recent 10 years were performed. The results showed that acupuncture could inhibit the inflammatory reaction, reduce oxidative stress injury, restrain brain edema formation, inhibit apoptosis, promote neural and vascular regeneration, etc. Acupuncture methods used included electroacupuncture, scalp acupuncture, eye acupuncture and "consciousness-restoring resuscitation needling", etc. The existing problem was that the intervention action of acupuncture was mainly focused on inhibiting inflammatory reaction and oxidative stress injury, and the study on apoptosis and neural and vascular regeneration was needed. It is suggested that from the aspect of multiple target points, the intervention mechanism of acupuncture for CIRI should be systemically studied in the future, which could provide new idea for clinical diagnosis and treatment on ischemic cerebrovascular diseases.

Objective: To study the effect of down-regulation of eukaryotic translation initiation factor 4E (EIF 4E ) induced by the siRNA expression plasmid on the proliferation and cell cycle of human breast cancer cell line MDA-MB-231. Methods: The siRNA expression plasmid pGPU6/GFP/Neo-EIF4E was constructed and then transfected into breast cancer MDA-MB-231 cells by LipofectAMINE2000. The expressions of EIF4E and cyclin D1 mRNAs and proteins were examined by RT-PCR, Western blotting and the immunocytochemistry method, respectively. The MTT method, plate colony formation assay and flow cytometry were performed to detect the proliferation ability, cell colony formation rate and cell cycle distribution of MDA-MB-231 cells transfected with siRNA expression plasmid. Results: The siRNA expression plasmid pGPU6/GFP/Neo-EIF4E was constructed successfully. The expressions of EIF4E and cyclin D1 mRNAs and proteins were all decreased markedly after transfection with pGPU6/GFP/Neo-EIF4E (P <0.05). The growth of MDA-MB-231 cells in the pGPU6/GFP/Neo-EIF4E-tranfected group was inhibited and the cell colony formation rate was statistically decreased (P<0.05) as compared with those in the blank control and the pGPU6/GFP-transfected groups. The result of flow cytometry showed that the percentage of cells in G1 phase in the pGPU6/GFP/Neo-EIF4E-tranfected group was higher than that in the blank control group (71.30%±0.47% vs 53.10%±0.43%); however, the percentage of cells in S phase was signifcantly lower (12.53%±0.13% vs 26.47%±0.38%, P <0.05). Conclusion: EIF 4E siRNA can downregulate EIF 4E gene expression in human breast cancer MDA-MB-231 cells, suppress cell proliferation to some extent, and increase the number of cells in G1 phase with a decreased number of cells in S phase. EIF 4E gene may become one of the important molecular targets to breast cancer. Copyright© 2011 by the Editorial Board of Tumor.

OBJECTIVE:To observe therapeutic efficacy and safety of nedaplatin combined with paclitaxel in the treatment of advanced cervical cancer. METHODS:Totally 100 patients with advanced cervical cancer were randomly divided into observation group(50 cases)and control group(50 cases). Both groups were given 6MV linear accelerator radiotherapy combined with intra-cavitary irradiation. Based on it,control group was additionally given Cisplatin injection 20 mg/m2,d1+Paclitaxel injection 35 mg/m2,d1 intravenously within 3 h. Observation group was additionally given Nedaplatin for injection 20 mg/m2,d1+Paclitaxel injection intravenously(same usage and dosage as control group). A treatment course lasted for a week,and both groups received 6 courses of treatment. Short-term efficacies of 2 groups were observed,and the levels of vascular endothelial growth factor A(VEGF-A), VEGF-C and VEGF-D,lymphatic microvessel density(LVD),microvessel density(MVD),toxic reaction were also observed be-fore and after treatment. RESULTS: Total response rate(52.00% vs. 32.00%)and disease control rate(86.00% vs. 66.00%)of ob-servation group were significantly higher than those of control group,with statistical significance(P<0.05). After treatment,the levels of VEGF-A,VEGF-C and VEGF-D,LVD,MVD in 2 groups were significantly lower than before treatment,and the obser-vation group was significantly lower than the control group,with statistical significance(P<0.05). The incidence of thrombocyto-penia in observation group was significantly higher than control group,and the incidence of nausea and vomiting was significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS: Nedaplatin combined with paclitaxel can im-prove short-term efficacy of patients with advanced cervical cancer,reduce gastrointestinal reaction,VEGF level and inhibit the generation of tumor vessel,but great importance should be attached to platelet toxic reaction.
