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 develop a kit of time?resolved fluoroimmunoassay(TRFIA)for detection of Schistosoma japonicum protein SjP38,and evaluate its effectiveness. Methods The anti 9G7 SjP38 monoclonal antibody was used as the capture anti?body coated with 96?hole plate,and the Eu3+labeled 1A6 monoclonal antibody was used as the detection antibody to establish the TRFIA SjP38 kit. In addition,the accuracy,sensitivity,precision,stability and coincidence rate to pathogenic diagnosis of the kit were evaluated. Results This established kit possessed high accuracy,wide linear range from 2 to 1 250 ng/ml,high sensitivity with the minimum detectable concentration of 0.14 ng/ml,and good precision(the coefficient variation of the intra?and inter?assay were 3.6%to 4.6%and 5.1%to 6.7%,respectively). The stability tests showed that the reagents could be stable for six months at 4℃,7 d at 37℃. The positive and negative corresponding rates to the pathogen detection method were 95%and 100%respectively. Conclusion All the performance and detection indicators of the kit have reached the requirements of clinical test,but its clinical application still needs further validation.

Purpose Medicine information and features of adverse reactions induced by non-ionic iodinated contrast agent injection for CT examination are analyzed and discussed,offering empirical evidence and reference for medication choice and patient information for clinical CT examination and targeted adverse reactions disposal.Materials and Methods General material,medicine type and name,adverse reactions occurrence time,symptoms and other information of the 20,418 patients receiving CT examination with non-ionic iodinated contrast agent at X-ray Department in Gansu Provincial Hospital from July 2013 to September 2016 were retrospectively analyzed.Results For observation objects in this group,11,679 were male and 8,739 female,aging from 3 to 93 and the average age was (52.1 ± 13.2) years.Various adverse reactions occurrence rate of non-ionic iodinated contrast agent was 0.4％ and adverse reactions occurrence rate of secondary hypertonic contrast and isotonic contrast agent was 0.47％ and 0.27％,respectively.Among the 81 adverse reactions,91.3％ were acute,among which 88.9％ occurred within 15 min after injection.8.7％ were delayed,97.6％ mild and moderate,and 2.4％ severe.Secondary hypertonic contrast and isotonic contrast agent occupied 74.0％ and 26.0％,respectively for the cause of adverse reactions.Delayed adverse reactions were mainly caused by isotonic contrast agent,representing as mild and moderate.Representation frequency of adverse reactions symptoms in turn was skin,digestive tract,central nervous system,respiratory system and circulatory system.Conclusion Adverse reactions caused by iodinated contrast agent were mainly acute and mild and moderate.The patients or their family members shall be fully notified before examinations.Severe adverse reactions caused by iodinated contrast agent developed very quickly and multi-systems would be damaged.Efficient on-site treatment is very important.Delayed reactions caused by isotonic contrast agent shall be paid more attention.
