Many college students’ English is not good enough to meet the need of the society. Pairing general English with ESP is proposed so as to solve the problem. Taking college English teaching in schools of traditional Chinese medicine as a case, this paper analyzes the key factors such as teaching materials, language teachers, students, teaching objectives, methods and environment in the teaching process in order to prove that pairing general English with ESP is feasible.

Objective　To investigate the correlation of pathology to immunology in animals with tuberculosis by molecular pathology. Methods　BALB/c mice were randomly divided into two groups: tuberculosis model (A) and control mice (N). Immunohistochemistry technology was used to investigate the correlation between the expression of IFN-γ, IL-4 and iNOS and the type as well as magnitude of tissue injury. Results　Two phases were observed during the 2nd week characterized by inflammatory infiltration in the alveolar-capillary interstitium and the tissues surrounding blood vessels. A predominance of TH1 cells was shown by a higher percentage of IFN-γ positive cells and a lower percentage of IL-4 positive cells in the inflammatory infiltrate identified by immunohistology. From the 4th week after infection to the end of experiment, we observed a chronic advanced phase characterized by pneumonia and local necrosis with a TH0 balance due to an equivalent proportion of IFN-γ and IL-4 positive cells in the lung lesions. The iNOS expression was increased in acute phase and decreased in chronic phase. Conclusion　There is a closely correlation on the kinetics of TH1/TH2 cells and iNOS expression with the type and magnitude of tissue injury during the infection of tuberculosis.

Objective To explore the effect of I kappa B kinase (IKK) on liver during hepatic ischemia reperfusion (HIR) in rats.Methods Wister rats were divided randomly into HIR group in which hepatic reperfusion was given after 60 minutes of ischemia by interruption of the arterial and portal venous blood supply to the left lobes and middle lobes of the liver; HIR + PDTC treatment group in which PDTC (120 mg/kg) were injected via the dorsum vein of penis before ischemia reperfusion; and sham control group in which midline laparotomy was performed without vascular occlusion and treatment.Expression levels of IKK were measured with In situ hybridization(ISH).The NF-κB activities were determined with EMSA.Expression levels of TNF-α were measured with immunohistochemistry (IH).Serum levels of ALT were measured.Results Expression level of IKK was increased markedly from 0 to 12h and peaked 6h after reperfusion in HIR group.NF-κB was activated 0 ～ 12h after reperfusion and activities of NF-κB were maximal 6h after reperfusion in HIR group rats compared with sham control group.Expression level of TNFα was increased markedly from 0 to 12h and peaked 6h after reperfusion in HIR group.Serum levels of ALT were increased significantly after reperfusion in H1R group.Expression level of IKK was lowered markedly in HIR + PDTC group from 0 to 12h after reperfusion.NF-κB activities were significantly lower in HIR +PDTC group than in HIR group from 0 to 12h after reperfusion.Expression level of TNF-α was lowered markedly in HIR + PDTC group as compared with HIR group from 0 to 12h after reperfusion.Serum level of ALT was decreased significantly after reperfusion in HIR + PDTC group as compared with HIR group.Conclusion HIR can activate IKK-β which promotes the activation of NF-κB,then NF-κB results in upregulation transcription of TNF-α gene which gives rise to the release of other inflammatory cytokines and triggers uncontrolled inflammatory response,and induces hepatic injury.Blocking IKK-NF-κB pathway may be an effective approach to checking the generation and development of ALI,PDTC plays important prophylaxis and treatment roles in hepatic injury after HIR.

Objective To investigate the response of retinal ganglion cells (RGC)in detached and reattached retina in adult rats, and the effect of IL-1beta antibody and IL-1Ra on the loss of RGC. Methods A total of 73 Sprague-Dawley (SD) rats were subretinally injected with healon GV(1.4% hyaluronate)and retrograde labeled with fluorogold (FG), and 10 ng IL-1Ra and 500 ng IL-1beta antibody were injected into the subretinal space combined with healon GV. The retinal flakes were observed under the fluoroscope and the number of RGC was counted 2 hours, 1, 3, 5, 7, 10, 20, 50, and 90 days after detachment; 10 days after detachment and 30 days after reattachement; 90 days after detachment and 20 days after reattachement, and 1 and 10 days after injection with IL-1beta antibody and IL-1Ra,respectively. And the control group was only developed an intraocular injection of the same valume of healon GV. Result Two hours after detachment, the RGC loss was found, reached the peak at first day, and decreased gradually. RGC loss was also found in the non-detached area. The reattachment 10 days after detachment (early reattachment) stopped the loss of RGC, and the reattachment 90 days after detachment (late reattachment) promoted the loss, which rested on a certain level. Subretinal space injection of IL-1Ra and IL-1beta antibody decreased the loss of RGCs in the detached retina. Conclusion The RGCs loss were found both in the detached and attached retina. Early reattachment may stop the loss of RGC, and late reattachment may promote the loss. Both IL-1beta antibody and IL-1Ra have neuroprotective effect on RGC.

The clinical practice in Pediatrics of Chinese medicine is the first step of the students to combine the theory with the clinical practice. The optimization teaching methods for clinical practice in Pediatrics of Chinese medicine was formed by using Delphi method of the extensive consultation from experts in colleges and universities of Pediatrics of Chinese medicine. We used this teaching method in students of Beijing University of Chinese medicine in 2011. Comprehensive evaluation to the implementation of effect was from assessment from students and analysis of exam results. The results showed that based on the survey of the students in the practice, the students in the experimental group give more positive evaluation than the control group on the necessity, satisfaction and harvest in the clinical practice in pediatrics of Chinese medicine.

Objective:To investigate the influence of propofol on the binding function of GABA A receptor. Methods: By using radioligand receptor binding assay, effects of propofol on the specific binding of 3H GABA and saturation curves of GABA A receptor were observed in cortical membrane preparations from mouse cerebral cortex. Results: Specific binding experiments showed that propofol at the concentrations of 10 300 ?mol/L markedly enhanced the specific binding of 3H GABA( P 0.05). Conclusion: Clinical concentrations of propofol can enhance the binding function of GABA A receptor through increasing the affinity of the low affinity binding site of GABA.

Discoidin domain receptor 2 (DDR2), a tyrosine kinase receptor belonging to DDRs family, is associated with progression of various cancers. Studies have indicated that DDR2 expression is upregulated in various cancer tissues, which could promote tumors proliferation, invasion, and metastases. Furthermore, patients with high DDR2 expression showed poor 5-year overall survival rate. In addition, DDR2 point mutation can enhance the sensitivity of tumor cells to small molecule tyrosine kinase inhibitor dasatinib, which suggests that DDR2 mutation may be a promising target for cancer therapy.

ObjectiveTo investigate the possible effect of interleukin-1β(IL-1β)in experimental retinal detachment,and the role in proliferation.MethodsThe experimental retinal detachment and reattachment in different time were made using Sprague-Dawley rats. The expression of proliferating cell nuclear antigen (PCNA) in neuro-retina was tested with flow cytometry at different time. IL-1β in neuro-retina were analyzed by labeling with polyclonal IL-1β antibody. The level of IL-1β in neuro-retina were tested with radio-immune method. IL-1β antibody 1000 ng,IL-1Ra 20 ng were injected in the subretinal space of some rats before PCNA reached to its high point respectively,and the expression of PCNA of them were compared with that of control which were injected with 0.01 M PBS.ResultsIL-1β expressed in Muller cell,astrocyte,vascular endothelial cell in neuro-retina and reached to its peak at the 7th day after detachment,then declined and continued at a low level as long as the retina detached.The expression of PCNA began at the second day after detachment, and reached a maximum at about 10 days after,then declined and continued at a low level as long as the retina detached. IL-1βantibody and IL-1Ra could restrain the expression of PCNA.ConclusionProinflammatory cytokine IL-1β is the key factor in proliferation of experimental retinal detachment.

Objective To evaluate effects of right ventricular septal pacing modes on treatment of heart failure.Methods Twelve dogs with heart failure were performed in every dog at random,and the pacing modes employed in the test included right atrium-right ventricular apex (RVA),right atrium-right ventricular septal(RVS),and right atrium-biventricular (Bi-V) ; The pacing frequency was 180 times per minute.The results were measured before pacing and after 15 minutes when the pacing became stable in Color Doppler echocardiography,including left ventricular end-diastolic diameter (LVEDd),left ventricular ejection fraction (LVEF),interventricular mechanical delay (IVMD),interventricular septum and left ventricular posterior wall motion delay (SPWMD),and left ventricular 12-segment peak time standard deviation (Ts-SD).Results Right ventricular septal pacing mode:(1)Compared with parameter before pacing and RVA pacing,LVEDd,IVMD,SPWMD,and Ts-SD decreased and LVEF increased,and the difference was significant(P ＜0.05).(2)Compared with Bi-V pacing,LVEDd,IVMD,and SPWMDandTs-SD increased and LVEF decreased,and the difference was significant (P ＜ 0.05).Conclusions Right ventricular septal pacing could improve ventricular synchrony and cardiac function partly,and the effect was better than right ventricular apical pacing but less than biventricular pacing,also could not be a alternative models of cardiac resynchronization therapy for heart failure.

Objective To study the cause,prevention and treatment of postpancreaticoduodenectomy hemorrhage.Method The clinical data of 422 patients who underwent PD in our hospital between January 2000 and January 2012 were retrospective analyzed.Results The incidence of postoperative hemorrhage was 8.1％ (34/422),and the mortality was 20.6％ (7/34).Early and delayed hemorrhage occurred in 19 and 15 patients,respectively.Intra-abdominal and gastrointestinal hemorrhage occurred in 20 and 14 patients,respectively.For the 19 patients who underwent reoperation,the mortality was 20.6％ (7/34).When compared with the delayed hemorrhage group,the mortality of the early hemorrhage group was significantly lower (P＜0.05).Conclusions Meticulous operation and reliable hemostasis during operation and prevention of pancreatic fistula,biliary fistula and peritoneal fluid collection after operation are the key points in reducing postoperative hemorrhage.A timely and decisive reoperation is important to manage postoperative hemorrhage.
