It is a trend that innovate the traditional bilingual education model and select a new teaching model.Code-switching is a lingual phenomenon when a passages or articles are expressed with two or more language.To guarantee effect of bilingual education and improve education quality,penetration bilingual education was applied during microbiology teaching.Professional English vocabulary,words,passages or articles were introduced to students timely and by measure by the way of language code-switching.The results showed that bilingual teaching mode with language code-switching inspire study emotion and self-confidence of English expression from students.

Objective To study CT findings of gastrointestinal lymphoma.Methods Conventional and enhanced CT data of 25 gastrointestinal lymphoma patients proved pathologically by gastroscope(8 cases),enteroscope(3),operation(5)and lymph node of neck puncture(9) were retrospectively analysed.Results All cases were secondary gastrointestinal lymphoma except one primary located in cardia.CT manifestations of gastric lymphoma included three kinds:(1)Widespread infiltration or multiple type (9 cases);(2)Limited type(3 cases);(3)polypus type(1 case):which had not been found by gastroscope.The CT value range of tumor was 20~42 HU with average of 31.3 HU.Most tumours showed homogeneous contrast enhancement.Enhanced value range of tumor was 15~33 HU with average of 23.5 HU.CT manifestations of intestinal lymphoma included:(1)Multiple nodus type(4 cases);(2)infiltration type(5 cases);(3)mesentery involved type(3 cases);(4)lump type(3 cases).Thickening mural were homogeneous except one showed low attenuation in the center of one extremely thickening wall.Conclusion Gastrointestinal lymphomas have slight to medium enhancement on comtrast-enhanced CT,while the medium enhancement is characteristic finding of this lesion.

Objective To investigate the effect of emergency case video segmentally introduction combining with simulation in cultivation of undergraduate nursing students′skills of trauma management. Methods A group of 55 undergraduate nursing students, recruited in the control group from September 2013 to April 2014, were instructed by traditional teaching method, the trauma management skill was delivered by lecture, video and group based practice. Another 50 undergraduate nursing students, recruited in the observation group from September 2014 to April 2015, were located in the simulation group, while the key point of trauma management was segmentally introduced by emergency case video, the skill of trauma management was delivered by lecture and video, a multiple injury case scenario was used for group practice. The score of the practice test and the evaluation of the teaching were compared among the two groups. Results The students in observation group demonstrated more skilled trauma management compared with that in the control group (90.42±8.50 vs. 84.68±8.77, t=3.56, P<0.05). The students in observation group presented significantly higher satisfaction with the teaching, improving study interesting 93.33%(56/60), promoting the theory knowledge deepen 91.67%(55/60), improving the ability of thinking and observation 95.00% (57/60/) , improving the ability of analyzing and solving problems 100.00% (60/60), enhancing the ability of independent learning 96.67%(58/60), while in the control group, they were 76.36%(42/55), 69.09%(38/55), 65.45%(36/55), 69.09%(38/55) and 80.00%(44/55), the differences between the two groups were significant (χ2 =2.30-4.40, P < 0.05). Conclusions Application of emergency case video segmentally introduction combining with simulation provided more opportunity to the undergraduate nursing students to apply relevant knowledge in analyzing and dealing with trauma cases, which contributes to the improvement of undergraduate nursing students′ skills of trauma management.

BACKGROUND:Sufentanil exerts protective effects on tissues, but its roles in the repair of nervous system injury and the underlying mechanism are stil unknown.
OBJECTIVE:To explore the protective effect of sufentanil preconditioning in the repair of spinal cord injuries and the underlying mechanism.
METHODS:Mouse models of spinal cord injuries were prepared through clipping spinal cord fol owed by intraperitoneal injection of 3 and 6μg/kg sufentanil, respectively.
RESULTS AND CONCLUISON:(1) Western blotting, ELISA and TUNEL assays showed that 6μg/kg sufentanil significantly down-regulated the protein expression levels of TLR4, nuclear factor-κBp65, cleaved-caspase 3, tumor necrosis factor-αand interlenkin-1βin the spinal cord of mice (P<0.05);at the same time, the number of apoptotic neurons was significantly decreased (P<0.05). (2) Furthermore, high-dose sufentanil preconditioning significantly ameliorated the recovery of limb function at 14 days after injury (P<0.05). (3) These results administrate that the neuroprotection provided by 6μg/kg sufentanil preconditioning for spinal cord injuries in mice maybe related to the TLR4/nuclear factor-κB signaling pathway inactivation.

Purpose To analyze the differences of CT manifestations, and to explore the disparity of drainage volume in early drainage between Klebsiella pneumoniae induced liver abscess and non-Klebsiella pneumoniae induced liver abscess. Materials and Methods 337 cases of patients whose blood culture or drainage fluid culture results were positive were divided into Klebsiella pneumoniae group (219 cases) and non-Klebsiella pneumoniae group (118 cases). CT characteristics of the two groups were analyzed, including lesion distribution, quantity, structure, texture, abscess wall thickness, enhancement character around the lesion, whether or not concurrent with thrombophlebitis or migratory infection and so on. Early drainage volume in interventional puncture drainage was observed in both groups. Results Chest CT showed that solitary, multi-room, solid, thin-walled abscesses with concurrent thrombophlebitis, migratory infection and no enhancement around tend to occur in Klebsiella pneumoniae group (χ2=4.065, 3.834, 4.682, 5.689, 5.215, 8.362, 8.407, P<0.01). Early drainage volume of Klebsiella pneumoniae group was significantly lower than that of non-Klebsiella pneumoniae group (χ2=5.863, P<0.01). Conclusion CT manifestations of Klebsiella pneumoniae induced liver abscess are solitary, multi-room, solid, thin-walled abscesses without enhancement around them, thrombophlebitis and migratory infection are common seen and drainage volume is less in early stage after interventional operation.
