Helicobacter pylori (H.pylori) infection is the most important pathogenic microorganisms associated with the development of chronic gastritis, peptic ulcer and gastric mucosa-associated lymphoid tissue lymphoma (MALT) in children. H.pylori infection may occur in early childhood and last a lifetime even directly affecting the health of adulthood unlessH.pylori infection was eradicated. This article aims to review the infection condition, infection pathway and immunological characteristics ofH.pylori and its relationship with extragastroduodenal diseases in children.

Objective To evaluate and compare the clinical applications of Disposcope (DS)en-doscope and GlideScope (GS)video laryngoscope in double-lumen endobronchial tube (DLT)intuba-tion of the patients with difficult airway.Methods Forty patients scheduled for elective thoracic sur-gery after failure to place the DLT with modified general laryngoscope 2 attempts were randomly dev-ided into 2 groups,20 cases in each group.Patients underwent DLT with DS (group DS)or GS (group GS)intubation after failure to intubation.The causes of the failure of intubation,the intuba-tion of the video laryngoscope,the time of intubation and the location of left double lumen tube were recorded.And the postoperative injury of oral mucosa,teeth and respiratory tract were observed. Results The causes of the difficulty for DLT intubation included:long,high arched palate,large epi-glottis,reduced jaw opening,protruding or loose incisors,over bite,reduced neck extension.The in-tubating achievement ratio was significantly higher in group DS than in group GS (P < 0.05 ).But there was no obvious difference between the two groups in the location success rate and intubation time.The postoperative incidence of tooth loss and oral mucosal injury was significantly higher in group GS than in group DS (P <0.05).Conclusion Both DS and GS were great helpful to intubation and location of DLT in the patients with difficult airway.But DS was more superior than that of GS in the difficult airway of reduced jaw opening,protruding or loose incisors,over bite and reduced neck extension.
