Objective To investigate the diagnostic value of serum procalcitonin (PCT) and C-reactive protein (CRP) in nonneutrocytic ascitic spontaneous bacterial peritonitis (NASBP).Methods From January 2012 to January 2015,patients with liver cirrhosis and ascites were restropectively enrolled.Patients were divided into NASBP group and non-infective ascites group.The receiver operating characteristics curve (ROC) was used for assessing diagnostic accuracy of serum PCT and CRP.Patients with conventional SBP were set as controls.Data between two groups were compared using t test,Rank sum test,x2 test or Fisher exact test.The areas under ROC curve or Youden indeces were compared using Z test.Results A total of 30 patients were collected in NASBP group,51 patients in non-infective ascites group and 33 patients in conventional SBP group.There were no statistically significant differences in PCT and CRP levels between NASBP group and conventional SBP group [0.70(0.25～2.45) μg/L,(21.85-±-16.46) mg/L;0.90(0.33～3.56) μg/L,(31.78-±26.74) mg/L] both P＞0.05,and were both significantly higher than those of non-infective ascites group (0.20 (0.07 ～ 0.40) μg/L,Z=-3.38,t=4.64;(7.19±7.04) mg/L,Z=-3.89,t=-5.17,both P＜0.05).The optimal cut-off value of PCT and CRP in the diagnosis of NASBP was 0.43 ng/mL and 12.76 mg/L,respectively.According to the cut-off value above,PCT,CRP and PCT plus CRP in series and in parallel in the diagnosis of NASBP,the areas under curves were 0.725,0.848,0.737 and 0.806,respectively,and there was no significant difference in pairwise comparison between groups.The sensitivities were 70.0％,70.0％,53.3％ and 86.7％,respectively,there were statistically significant differences between inparallel and any other method (Fisher exact test,all P＜ 0.05).And there was no statistically significant difference (all P＞0.05).The specificities were 76.5％,88.2％,94.1％ and 74.5％,respectively.There was no statistically significant difference in PCT and CRP between combination in parallel and in series,while the differences in the other pairwise comparisons of combinations were statistically significant (Fisher exact test,P＜0.05).The Youden's indexes were 0.465,0.582,0.474 and 0.612,respectively,there was no statistically significant difference in pairwise comparison between groups (all P＞0.05).Conclusions All of serum PCT,CRP and the combination of them have good diagnostic value in NASBP with their own advantages which should be selected based clinical needs.

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.

Non-muscle invasive bladder cancer (NMIBC) represents the malignant tumor of urinary bladder which is limited to mucosa and submucosal.NMIBC has high recurrence,and can progress to muscle invasive bladder cancer.Adjuvant intracavitary perfusion is beneficial for patients after surgery.There are many drugs for intravesical instillation in clinic.However,the new bladder perfusion drug which is safer and more effective,is always a research hotspot.

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 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.

Objective:cDNA microarrary technique was employed to detect the effects of evodiamine on functional regulation of gene expressing in murine marrow-derived dendritic cells.Methods:Immature dendritic cells (iDC) derived from bone marrow of BALB/c mice were induced by GM-CSF for ten days in vitro and received corresponding treatment for 24 h.Then the cell were randomized into the control groups (Ⅰ),evoamine group (Ⅱ),LPS group (Ⅲ) and evodiamine+LPS group (Ⅳ).After 24 h’s treatment, total RNA of the cells was collected,and cDNA microarrary (GEArray S Series Mouse Dendritic & Antigen Presenting Cell Gene Array:MM-604) was used to screen the functionalg correlation genes of dendritic cells.Results:There were seven genes up-regulated and two genes down-regulated two-folds above in Ⅱ/Ⅰ;thirty four genes up-regulated and twelve genes dwon-regulated two-folds above in Ⅲ/Ⅰ;forty six genes up-regulated and seven genes down-regulated two-folds above in Ⅳ/Ⅱ;twenty four genes up-regulated and two genes down-regulated two-folds above in Ⅳ/Ⅲ.The function of these genes involve the secret of the cytokines and the expression of their receptors,antigen uptake,antigen presentation,cell surface receptors and signal transduction.Conclusion:The effects of evodiamine on dendritic cell involve in multi-regulation and expression of genes,these genes contribute to the functions,differentiation and maturation of the dendritic cells.The work provides a potentiality to seek the target of medicine.

Objective To investigate the exposure level to vehicle exhaust pollution for population by different commuting modes in roadside environment in Wuhan. Methods Eight air monitoring sites were selected in the six main roads in urban area of Wuhan, Hubei province. The concentrations of NO2, CO, total hydro carbon (THC), PM10, benzene, toluene and xylenes (BTX) emitted from the vehicles were monitored and analyzed in winter and summer of 2007, respectively and combined with breathing rate and time spent of the population in traffic environments, exposure doses of different subpopulation were calculated as indicators in order to evaluate their exposure level to traffic exhaust. Results The PM10 was the primary pollutant on the roadside. Compared with the Ambient Air Quality Standard, the rate of exceeding standard limit for PM10 was 8% in summer and 100% in winter. As for on the roadside, the exposure level for adults was higher than that for the children (P
