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 explore the effect of robot-assisted gait training on the lower limb motor function and gait ability in patients with hemiplegia after stroke. Methods From January, 2015 to October 2016, 60 patients with hemiplegia after stroke were randomly divided into control group (n=30) and experimental group (n=30). Both groups received conventional rehabilitation, while the experimental group was given robot-assisted gait training and the control group was given artificial assisted gait training, 30 minutes a day, five days a week for eight weeks. They were evaluated with Fugl-Meyer Assessment-Lower Limb (FMA-LE), muscle strength of hip flexion (L-FORCE/HIP/Flex, FHF) and knee extension (L-FORCE/KNEE/Ext, FKE), Six Minutes Walking Distance and Ten Meters Walking Time before and after training. Results There was no significant difference in general data and all indexes between two groups before training (P>0.05). The scores of all the indexes improved in the experimental group after training (t>2.274, P<0.05), and all of them were better in the experimental group than in the control group (t>2.095, P<0.05), except FKE. Conclusion Robot-assisted gait training can effectively improve the lower limb motor function and gait ability of patients with hemiplegia after stroke.

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.

OBJECTIVE:To study the mechanism of improvement effects of exenatide on mitochondrial function of H9c2 cells under hypoxia/reoxygenation (H/R) condition. METHODS:H9c2 cells were cultured in vitro and were divided into blank control group,drug control group(exenatide 200 nmol/L),model group(H/R),pretreatment group(exenatide 200 nmol/L+H/R),gluca-gon-like peptide-1 receptor (GLP-1R) inhibitor [Exendin-(9-39) 100 nmol/L+exenatide 200 nmol/L+H/R], cAMP inhibitor (Rp-cAMPS 1 μmol/L+exenatide 200 nmol/L+H/R)group and PKA inhibitor(H-895 μmol/L+exenatide 200 nmol/L+H/R)group. Except for first 2 groups,H/R model was established in other groups,and they were given exenatide 30 min before modeling and relevant inhibitor 10 min before giving exenatide. Morphology of mitochondria was observed by TEM,and mitochondrial calcium (Ca2+m)and the mitochondrial membrane potential(ΔΨm)were determined by flow cytometry. Cellular ATP content was measured by microplate reader. RESULTS:Compared with blank control group, mitochondrial cristae swelling was enhanced in model group,while density decreased,showing vacuolization;Ca2+m level increased while ΔΨm and ATP decreased (P<0.05). Com-pared with model group,mitochondrial cristae swelling relieved in pretreatment group,while density increased,showing vacuoliza-tion relieved;Ca2+m level decreased,while ΔΨm and ATP increased(P<0.05). Compared with pretreatment group,the levels of Ca2+m increased in 3 kinds of inhibitors group,while ΔΨm and ATP decreased(P<0.05). CONCLUSIONS:Exenatide attenuates H9c2 cell mitochondria Ca2+m accumulation,increases ΔΨm and ATP production. Which indicate its mechanism may be associated with activating GLP-1R/cAMP/PKA pathway.

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.
