OBJECTIVE:To observe clinical efficacy and safety of tiotropium bromide combined with budesonide formoterol in the treatment of severe bronchial asthma in adults. METHODS:A total of 110 adult patients with severe bronchial asthma were selected from our hospital during Mar. 2013-Mar. 2016 were divided into control group and observation group according to random number table,with 55 cases in each group. Control group was given Budesonide formoterol powder for inhalation,2 inhalations each time,bid;observation group was additionally given Tiotropium bromide powder for inhalation 18 μg,qd,on the basis of con-trol group. Both groups were treated for 6 months. Clinical efficacies as well as ACT scores,respiration function indexes and the times of acute attack of asthma before and after treatment,the occurrence of ADR were compared between 2 groups. RESULTS:The efficiency rate and total response rate of observation group were 54.55% and 96.36%,which were significantly higher than 32.73%,78.18% in control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in ACT scores,respiration function indexes or the times of acute attack of asthma between 2 groups(P>0.05). After treatment,ACT scores of 2 groups were significantly higher than before treatment;FEV1,FEV1/FVC and PEF were significantly greater than be-fore treatment,PEFR was significantly lower than before treatment;and the indexes in observation group was significantly better than control group,with statistical significance(P<0.05). 1,3,6 months after treatment,the times of acute attack of asthma in 2 groups were significantly less than before treatment,and that in observation group was significantly less than control group,with statistical significance(P<0.05). The incidence of ADR in observation group was 20.00%,and there was no statistical signifi-cance compared to 14.55% of control group(P>0.05). CONCLUSIONS:Tiotropium bromide combined with budesonide formoter-ol in the treatment of severe bronchial asthma in adults can effectively relieve the severity of disease,improve respiration function, reduce the times of acute attack of asthma,and have good therapeutic efficacy and safety.

Objective:To screen the neutralizing epitope of enterovirus 71 (EV71) and determine the specific minimum amino acid sequence that triggers immunity for providing a theoretical basis for the development of synthetic peptide vaccines.Methods:EV71 neutralizing antibody-specific binding clones were panned and sequenced using a phage display random 12-peptide library to obtain the key sequences of neutralizing epitopes. A series of peptides containing the key sequences with N-terminal acetylation (AC) and C-terminal linking to Keyhole limpet hemocyanin (KLH) were synthesized. Serum samples were collected after immunizing mice with the modified peptides. Then the immunogenicity of the peptides and the neutralizing activity of serum samples were analyzed by Western blot, ELISA and neutralization test.Results:After three rounds of panning, cloning and sequencing, KQEKDL was identified as the key motif. The serum samples collected from the mice immunized with the modified series of peptides containing key motifs had different degrees of binding ability to EV71 and VP1 protein. The serum samples of mice immunized the synthetic peptide containing only the minimum key motif (AC-KQEKDL-KLH) had the strongest response to the other three peptides and EV71 and the highest neutralizing titer.Conclusions:The EV71 neutralizing epitope was successfully screened using the phage display random peptide library. The key motif of KQEKDL might be the specific minimum amino acid sequence that triggered the immune system. This study provides a theoretical basis for better understanding the immune response mechanism, evaluating the immunogenicity of the antigens and further research and development of polypeptide vaccines.

Objective:To compare the ability of platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) in evaluating the prognosis of patients with TNM stageⅠto Ⅲ gastric cancer.Methods:From May 2001 to December 2013, the clinicopathological data of 645 patients with gastric cancer treated at Harbin Medical University Cancer Hospital were retrospectively analyzed. Chi-square test was used to analyze the differences between NLR, and PLR and clinicopathological characteristics of patients. Kaplan-Meier method and log-rank test were performed to compare the overall survival of patients. Cox proportional hazards regression model was performed to analyze the prognosis of gastric cancer patients. The ability of NLR and PLR to evaluate the prognosis of gastric cancer was compared by receiver operating characteristic curve.Results:The cutoff values of PLR and NLR were 141.50 and 1.94, respectively. PLR was associated with gender, resection method, maximum diameter of tumor, whether chemotherapy, T-stage, N-stage, TNM stage, tumor location, white blood cell, hemoglobin, albumin, and whether total gastrectomy ( χ2=9.224, 10.577, 28.825, 6.831, 29.059, 28.637, 30.748, 18.023, 24.320, 77.274, 9.021 and 10.745, all P<0.05). NLR were associated with resection method, maximum diameter of tumor, T-stage, N-stage and TNM stage, white blood cell, hemoglobin and albumin ( χ2=14.563, 12.092, 22.697, 44.735, 34.151, 7.949, 9.611 and 7.498, all P<0.05). The results of multivariate analysis showed that resection method, whether chemotherapy, T-stage, N-stage, PLR and whether total gastrectomy were all independent risk factors for gastric cancer patients ( χ2=23.653, 22.023, 16.697, 24.038, 4.110 and 22.364, all P<0.05). The five-year cumulative survival rate of the patients with PLR<141.50 was higher than that of patients with PLR≥141.50 (55.4% vs. 30.5%), and the difference was statistically significant ( χ2=47.968, P<0.01). The AUC value of PLR in prognostic evaluation of gastric cancer was 0.629, which was higher than that of NLR (0.596, P<0.01). Conclusion:PLR is better than NLR in the prognostic evaluation of gastric cancer patients.

OBJECTIVE:
To compare the clinicopathological features and the prognosis between patients with adenocarcinoma of esophagogastric junction (AEG) and with adenocarcinoma of gastric antrum (AGA), and to investigate the prognostic factors of AEG and AGA.
METHODS:
A retrospective cohort study was performed on clinicopathological data of 239 AEG patients (AEG group) and 313 AGA patients selected simultaneously (AGA group) undergoing operation at Harbin Medical University Cancer Hospital from January 2001 to December 2012.
INCLUSION CRITERIA:
(1) receiving radical surgery (R0 resection); (2) AEG or AGA confirmed by pathological examination of postoperative tissue specimens; (3) without preoperative neoadjuvant radiotherapy or chemotherapy; (4) complete clinicopathological and follow-up data; (5) patients who died of non-tumor-related causes were excluded. Chi-square test and independent samples t-test were used to determine differences in clinicopathological factors between two groups. The overall survival (OS) of patients was compared by Kaplan-Meier method and Log-rank test. Multivariate prognosis analysis was performed using Cox proportional hazards regression model.
RESULTS:
As compared to AGA group, AEG group had higher proportion of male [82.0%(196/239) vs. 65.2%(204/313),χ²=19.243,P<0.001], older age [(60±10) years vs. (55±12) years, t=4.895, P<0.001], larger tumor diameter [(5.6±2.4) cm vs. (5.0±3.3) cm, t=2.480,P=0.013], more T4 stage[64.8%(155/239) vs. 55.6%(174/313),Z=-3.998, P<0.001], and more advanced tumor stage [stage III:60.7%(145/239) vs. 55.6%(174/313),Z=-2.564,P=0.010]. There were no statistically significant differences in serum albumin or hemoglobin between two groups (all P>0.05). The 5-year OS rate was 33.5% and 56.9% in AEG group and AGA group respectively and the median OS was 60.0(3.0-60.0) months and 33.6(3.0-60.0) months respectively; the difference was statistically significant (P<0.001). In AEG group, univariate analysis showed that differences of hemoglobin level (5-year OS rate: 24.0% for <130 g/L, 39.9% for ≥130 g/L, P=0.006), tumor diameter (5-year OS rate: 41.9% for <5 cm,28.8% for ≥5 cm, P=0.014), N stage (5-year OS rate: 42.2% for N0, 40.9% for N1, 31.7% for N2, 15.8% for N3a, 9.0% for N3b, P<0.001) and TNM stage (5-year OS rate: 56.2% for stage I, 38.5% for stage II, 28.3% for stage III,P=0.017) were statistically significant (all P<0.05); multivariate analysis revealed that the worse N stage was an independent risk factor of prognosis survival for AEG patients(HR=1.404,95%CI:1.164-1.693, P<0.001), and serum hemoglobin level ≥130 g/L was an independent protective factor of prognosis survival for AEG patients (HR=0.689,95%CI:0.501-0.946,P=0.021). In AGA group, univariate analysis showed that differences of serum albumin (5-year OS rate: 49.1% for <40 g/L, 61.1% for ≥ 40 g/L, P=0.021), tumor diameter (5-year OS rate: 74.2% for <5 cm, 39.9% for ≥ 5 cm, P<0.001), T stage (5-year OS rate: 98.3% for T1,83.3% for T2,50.0% for T3,36.8% for T4, P<0.001), N stage (5-year OS rate: 89.0% for N0, 62.3% for N1, 50.0% for N2, 33.9% for N3a, 10.3% for N3b, P<0.001) and TNM stage (5-year OS rate: 97.3% for stage I, 75.8% for stage II, 32.8% for stage III, P<0.001) were statistically significant (all P<0.05); multivariate analysis revealed that the worse T stage (HR=1.516,95%CI:1.060-2.167,P=0.023) and the worse N stage (HR=1.453,95%CI:1.209-1.747,P<0.001) were independent risk factors for prognosis of AGA patients.
CONCLUSIONS
As compared to AGA, AEG presents have poorer prognosis,and is easier to present with later pathological stage and larger tumor diameter. N stage and hemoglobin level are independent factors associated with the OS of AEG patients. T stage and N stage are independent factors associated with the OS of AGA patients.
