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.

Objective To systematically review the correlation between polymorphisms of CYP2D6 genotypes and concentrations of tamoxifen and its activity in Chinese breast cancer patients.Methods Such databases as Cochrane Library, PubMed, EMBase, CNKI, CBM, WeipuData and WanfangDate,from January 1995 to October 2014 were searched on line for the studies about the correlation between polymorphisms of CYP2D6 genotypes concentrations of tamoxifen and its activity in Chinese breast cancer patients.And references about it were checked.The meta-analysis was performed with RevMan 5.3 software.Results A total of 4 articles involving 438 patients were included.The results of meta-analysis showed that,the concentrations of HTAM and endoxifen in patients who had CYP2D6*10/*10 genotypes were lower than the other genotypes ( P<0.0001 ) .The concentration of tamoxifen in patients who had CYP2D6*10/*10 genotypes was lower than CYP2D6Wt/Wt ( P<0.05 ) .There was no significant difference between CYP2D6Wt/Wt and CYP2D6Wt/*10.Conclusion We concluded that CYP2D6 polymorphisms may influence concentrations of tamoxifen and its activity in Chinese breast cancer patients.

[Objective] To observe the effect of different acupoint application therapies :a summer treatment for the winter disease on allergic rhinitis ,and compare the relationship between the different acupoints and therapeutic effect. [Methods ] The 81 cases of allergic rhinitis who met inclusion criteria were divided into 12 acupoint group and 6 acupoint group. The time of application was in first ten-day period of the hot season. The duration of application was 2h. The days later, namely in the second ten-day period of the hot season, and twenty days later, in the third ten-day period of the hot season, the application was repeated respectively. Before treatment and half year after the treatment, the score of quality of life, symptoms of allergic rhinitis were observed to compare the relationship between the different acupoints and therapeutic effect. [Results] The effective rate was higher in 12 acupoints group than 6 acupoints group. After treatment, the score of quality of life, symptoms of allergic rhinitis were significantly improved( P<0.05 or P<0.01). And the comparison of the therapeutic effect of two groups showed significant difference in statistics( P<0.01). [Conclusion] The acupoint application therapy is effective for allergic rhinitis, and the comprehensive combination of acupoint is influential on the effect.

Objective To observe the effects of Kuijiening Plaster point application on the levels of pro-inflammatory cytokines IFN-γ, IL-12 and anti-inflammatory cytokines IL-4, IL-10 in serum and colonic tissue of ulcerative colitis (UC) rats with spleen-kidney yang deficiency; To investigate the possible mechanism of Kuijiening for the treatment of UC with spleen-kidney yang deficiency. Methods Sennae Folium solution gavage, ice water stimulation and trinitrobenzene-sulfonic acid ethanol combinative methods were applied to establish the models of UC rats with spleen-kidney yang deficiency. Rat models were randomly divided into control group, model group, application group and SASP group, 10 in each group. The control group and model group were given medicine-free cataplasm matrix point application and perfused with NS. The application group was given Kuijiening Plaster point application and perfused with NS. SASP group was given medicine-free cataplasm matrix point application and perfused with SASP. The courses were 28 days. General conditions of rats in each group were observed during treatment. The general morphology and pathological form of colonic tissue were observed with naked eye and light microscopy through HE staining respectively in each group post-treatment. Pathological features were observed and scored by HE dyeing. Levels of IFN-γ, IL-12, IL-4 and IL-10 in serum and colonic tissue of rats in each group were detected with ELISA. Results The general conditions, gross morphology and optical microscope pathological morphology of colonic tissue improved and scores decreased in application group and SASP group. Compared with the model group, levels of IL-4 and IL-10 significantly increased, while the levels of IFN-γ and IL-12 decreased in serum and colonic tissue in application group and SASP group, with statistical significance (P<0.01). Moreover, levels of IL-4 and IL-10 in application group decreased not as much as those in SASP group, while IFN-γ and IL-12 concentration increased higher than SASP group, without statistical significance (P>0.05). Conclusion Kuijiening Plaster point application can play a role in treating UC with spleen-kidney yang deficiency through partially restoring the balance between pro- and anti-inflammatory cytokines in serum and colon tissue of rats.
