Objective To explore the screenplay dialogue pattern in the interrogation of the second classroom training effect, so as to improve the quality of the inquiring teaching.Methods 69 five-year students of clinical medicine specialty of Grade 2014 in our university were randomly divided into the control group (34 persons) and the experimental group (35 persons), The students in the control group, during the second class-room training, received the consent of the patient, and informed the patient,to answer the illness according to the truthdo not disclose the diagnosis and treatment after hospitalization and other matters needing attention. Besides, we also arranged for students to conduct repeated bedside inquiry training. While the experimental group carried out the script dialogue model training on the campus. The teacher provided a script for interroga-tion. Students answered in accordance with the principle ofdon't ask don't answer, don't say anything other than the question, don't miss the question, don't answer the question wrongly. SPSS 19.0 was used for statistical analysis, and the comparison of measurement data between groups was performed by t test.Results There was no significant difference between the experimental group and the control group in the inquiry and assessment. The results showed that the training effect of the two groups was basically the same. Through the analysis of various aspects of inquiry, the chief complaint and communication ability of students in the experimental group were better than those in the control group, and the difference was statistically significant, which showed that the script dialogue model promoted students' ability of inducing complaints and their language ability when they did medical history collection.ConclusionTaking screenplay dialogue mode in the second classroom practice is good, which improves the students' enthusiasm, trains their clinical thinking and improves the teaching quality.

Objective To investigate whether Danhong injection can enhance the therapeutic effect of neural stem cell (NSC) transplantation in repairing cerebral ischemia injury by regulating the nuclear factor E2-related factor 2 (Nrf2) signaling pathway. Methods Forty male SD rats were randomly divided into the NSC transplantation group (NSC group), Danhong injection group (DH group), NSC+ Danhong injection group (N+D group), NSC+ Danhong injection group +ML385 group(N+D+M group) and PBS control group (PBS group), 8 rats in each group. All rat models of cerebral ischemia were established by embolization of the middle cerebral artery. Reperfusion was performed at 1.5 h after embolization. All rats in each group received corresponding interventions at 3 d after reperfusion. The neurological function score was evaluated before and 1, 2, 4 weeks after NSC transplantation. All rats were sacrificed at 4 weeks after NSC transplantation. The parameters related to oxidative stress were detected. The expression levels of neuron-specific nuclear protein (NeuN) and von Willebrand factor (vWF) were determined by immunofluorescence staining. Results Before NSC transplantation, the neurological function scores did not significantly differ among different groups (all P > 0.05). At postoperative 1, 2 and 4 weeks, the neurological function scores in the NSC, DH and N+D groups were significantly lower than those in the PBS and N+D+M groups (all P < 0.05). Compared with the PBS and N+D+M groups, the malondialdehyde (MDA) levels were significantly decreased, whereas the superoxide dismutase (SOD) and glutathione peroxidase (GPX) levels were considerably increased in the NSC, DH and N+D groups (all P < 0.05). The GPX level in the N+D+M group was significantly lower than that in the PBS group (P < 0.05). Immunofluorescence staining showed that the transplant NSC in the rat brain migrated to the surrounding area of cerebral infarction and survived, and expressed neuronal marker NeuN and neovascularization marker vWF. However, the number of living NSC in the N+D+M group was significantly lower compared with those in the remaining groups. Conclusions Danhong injection may improve the microenvironment of stem cell transplantation, enhance the survival rate of transplant NSC and improve the therapeutic effect of NSC transplantation for cerebral ischemia injury probably by regulating the Nrf2 signaling pathway.
