Objective To discuss the feasibility and safety of sevoflurane inhale anesthesia with portable combined inhalation anesthesia induction device in solving the difficulty of children entering the operation room.Methods One hundred pediatric patients were enrolled into the study.The pediatric patients were randomly divided into two groups,50 cases in each group.Group A was fraught with a new mode of administration,using portable combined inhalation anesthesia induction device with sevoflurane 2 ml before entering the operation room;group B was fraught with a traditional mode of administration,using in-tramuscular injection with ketamine 4-5 ml/kg before entering the operation room.The analog scale of anes-thetic effect,the number of body movement,adverse reaction were compared between the two groups. Results Compared with group B,time of falling asleep and retention time in the operating room was signif-icantly shorter (P <0.01).And body movement during vein puncture decreased significantly (P <0.01). Moreover,the incidence of adverse affect showed significant reduce compared with group B (P < 0.05 ). Conclusion The combined inhalation anesthesia induction device is simple to produce and easy to carry.To solve the difficulty of convoying children into the operating room,combined inhalation anesthesia induction device with sevoflurane is more effective, safer and more humanized way when compared with the traditional one.

Objective To investigate the effect of overexpression of miR-30b on the proliferation,cell cycle,apoptosis and invasion of gastric cancer cell line SGC-7901 and AGS,and the inhibitory effect on the tumor formation in vivo.Methods SGC-7901 and AGS cells were transfected with miR-30b mimics and miR-control,and qRT-PCR was used to detect the expression levels of miR-30b.Western blot assay was used to detect the expression of eIFSA2 protein.CCK-8 assay was used to measure the cell proliferation.Flow cytometry was used to analyze cell cycle and apoptosis.Transwell assay was used to detect cell invasion.In addition,the SGC-7901 and AGS cells transfected with miR-30b mimics and miR-control were injected into nude mice to observe the tumor formation and the expression of eIFSA2 protein in vivo.Results Results of qRT-PCR showed that the relative expression of miR-30b was significantly higher than that of miR-control group (P < 0.05).Western blot assay showed that the expression of eIF5A2 protein was decreased in miR-30b mimics group.CCK-8 assay showed that cell proliferation was inhibited in miR-30b mimics group.The result of flow cytometry showed that the cell cycle decreased and the apoptosis increased in miR-30b group.Transwell assay showed that the cell invasion was significantly lower in miR-30b group than that of control group (P < 0.05).Overexpression of miR-30b inhibited the formation of tumor and decreased the expression of eIF5A2 protein in vivo.Conclusion Overexpression of miR-30b inhibits the proliferation,invasion and tumor formation of gastric cancer cells,and reduces the expression of eIF5A2 protein,which provides a potential target for gastric cancer treatment.

Objective:To explore the effects of the scaffolding-based flipped classroom approach in the teaching of Infectious Disease Nursing. Methods:We assigned 152 students of nursing and midwifery majors of grade 2018 (experimental group) to be taught using the scaffolding-based flipped classroom approach and 182 students of grade 2017 (control group) to be taught using the traditional lecture method. Teaching effects were evaluated through students' exam performance and a questionnaire survey. Numerical data were analyzed using the χ2 test and t test with the use of SPSS 18.0, and text data were processed using NVivo 11 for thematic analysis. Results:The experimental group and control group showed significant differences in the interim exam score (83.19±7.96 vs. 79.62±3.14, P<0.001) and final exam score (78.47±6.92 vs. 73.16±8.24, P<0.001). The students of grade 2018 had a high level of participation in online learning. The questionnaire results showed that the scaffolding-based flipped classroom was well recognized in terms of students' overall perception, perceived course quality, perceived value of learning, and satisfaction and the open-ended question, with low scores for learner complaints and loyalty. Conclusions:The scaffolding-based flipped classroom is feasible in the teaching of Infectious Disease Nursing, which can improve students' academic performance and overall competence.
