Using colon adenocarcinoma cell line HT-29 as testing material, adhesion test was carried out for 24 strains of Bifidobacteria isolated from dejecta of longevous people aged one hundred years. The results showed that all strains could adhere to colon adenocarcinoma cells HT-29, among which the strains of TTF, Z2, TZ5 and (J-1) showed higher adhesive capability. Thus these four strains of Bifidobacteria were further tested for their endurance to stomach acid and bile acid. The production of vitamin B by these bacterial were also tested. All these tests indicated that the strain of TTF has high ability to produce Vitamin B_(1), B_(2), B_(6), B_(12), The survival rate after the treatment under pH 3.0 for 120 min was 93.11%, at the same time, the strain TTF can survive after being treated with 2% bile acid for 24h.

The immunoregulation effect to polysaccharides from Bifidobacterium spp. was investigated on the base of functional assessment standards of health food. Effects of the EPS on immunity were investigated by promoted the proliferation of spleen lymph cells, delayed type hypersensitivity reaction, the HC50 value and macrophage function assay in mice. Data showed that the EPS could obviously increase the ratio of swallowed chicken red blood cell by macrophage and the HC50 value in mice. However, no significant effect was found on the delayed type hypersensitive induced by sheep red blood cell, for only the low dose of 100 mg/(kg?d) EPS promoted the proliferation of spleen lymph cells. Bifidobacterium spp. EPS can certain immunomodulating function.

Objective We sought to compare the ability of MEWS score,APACHE Ⅱ score and combination of the two scoring systems to predict the prognosis of patients in emergency medical department.Methods During January to March 2014,640 patients in emergency medical department who met the criteria were set as the research object.The patients admission was the starting point for clinic observation.The relevant data were collected for carrying on the MEWS and APACHE Ⅱ ratings,tracking the patients' prognosis.The corresponding predictors for prognosis of patients such as sensitivity,specificity,positive predictive value,negative predictive value and ROC curve by MEWS score,APACHE Ⅱ score and combination of the two scoring systems were compared.Results The area under the receiver operating characteristic curve was 0.93,0.79 and 0.93 with MEWS score,APACHE Ⅱ score and combination of the two scoring systems.The comparison of either of the two scoring systems showed significant difference.When death was named as the prediction factor,the sensitivity,specificity,positive predictive value and negative predictive value were 76.92%,91.70%,51.02%,97.23% for MEWS score; 83.08%,62.80%,20.15% and 97.04% for APACHE Ⅱ score; 92.31%,86.43%,43.48% and 97.58% for combination of the two scoring systems.Conclusions Combination of the MEWS and APACHE Ⅱ scoring systems can be used to predict the prognosis of patients in emergency medical department.It posesses high sensitivity,specificity,positive predictive value and negative predictive value,which indicating a high predictive capability.

Objective To evaluate the efficacy and safety of olopatadine hydrochloride for the treatment of chronic idiopathic urticaria (CIU). Methods A multicentre, double-blind, randomized, parallel-group, controlled clinical trial was conducted. A total of 144 patients with CIU from 3 research centers were enrolled into this study, and randomly and equally divided into a test group and a control group. The test group administrated olopatadine hydrochloride 5 mg twice a day for 28 consecutive days, while the control group administrated levocetirizine hydrochloride 5 mg in the forenoon and a placebo tablet of olopatadine hydrochloride 5 mg in the afternoon for 28 consecutive days. The symptom score reducing index(SSRI)served as the primary outcome, and global assessment score for efficacy and total response rates as the secondary outcome. Results Totally, 137 patients completed the trial, including 70 in the test group and 67 in the control group. As intention-to-treat analysis showed, there were no significant differences in the total response rate between the test group and control group on day 7 (64.29% (45/70)vs. 56.72%(38/67), P > 0.05), 14(82.86%(58/70)vs. 74.63%(50/67), P > 0.05), or 28(87.14%(61/70)vs. 77.61%(52/67), P >0.05)after start of treatment. The SSRI was significantly higher in the test group than in the control group after 4 weeks of treatment(82.67% ± 22.70% vs. 70.51% ± 32.07%, P < 0.05). In addition, no significant difference was observed in the incidence of adverse reactions between the test group and control group(33.80%(24/71)vs. 27.94%(19/68), P > 0.05), and adverse reactions mainly included lethargy, dry mouth, fatigue, etc. Conclusion Olopatadine hydrochloride is effective and safe for the treatment of CIU.

Objective To explore the prognosis related genes of pancreatic ductal adenocarcinoma (PDAC)and investigate the molecular regulation mechanism.Methods Gene expression data of 102 PDAC patients with complete clinical survival data were selected from gene expression database of National Center for Biotechnology Information.The 106 transcription regulation gene collection was collected from Transfac database.The 715 microRNA (miRNA)target regulation gene collection was selected according to PicTar and TargetScanS method.Biological pathway data obtained from the Kyoto Encyclopedia of Genes and Genomes (KEGG).The known cancer genes were collected from the cancer gene census (CGC) database.Univariate Cox proportional hazards model was used to analyze the correlation between gene expression data and survival time,then obtained survival related candidate genes from the whole genome. Then the enriched genes were analyzed by hypergeometric distribution algorithm from three databases. Multiple correction testing was performed by BH-FDR method (FDR < 0.05 ).Kaplan-Meier was performed for survival curve analysis of PDAC.Results The results of data of 102 PDAC patients analyzed by univariate Cox proportional hazards model indicated that 273 genes were significantly related to the survival time of patients (P <0.000 1 ).After 273 survival genes were enrichment analyzed in 106 transcription factor regulation gene collection,12 survival genes enriched transcription factor target gene sets were found.After 273 survival genes were enrichment analyzed in 715 miRNA target regulation gene collection,11 survival genes enriched miRNAs target sets were discovered.After 273 survival genes were enrichment analyzed in pathway data of KEGG,15 survival genes enriched pathways were obtained. Period circadian clock 2 (PER2 )was regulated by CCAAT/enhancer binding protein (CEBPA)at transcription level and regulated by miRNA-32 after transcription.The prognosis of PDAC was affected by circadian rhythm pathway.The 102 patients with PDAC were ranked according to the expression of PER2 from high to low,the first 51 cases were included in PER2 higher expression group and the left were included in PER2 lower expression group.Kaplan-Meier survival analysis indicated that PER2 was significantly correlated with prognosis of PDAC (P <0.01 ).Conclusion CEBPA/miRNA-32/PER2 and its related circadian clock pathway may be the target pathway in interfering the development of PDAC,and is correlated with the prognosis of PDAC.

Class Ⅱa bacteriocins can be considered as the major subgroup of bacteriocins from lactic acid bacteria, not only because of their large number, but also because of their activities and potential applications. They have first attracted particular attention as listericidal compounds and are now believed to be the next in line if more bacteriocins are to be approved in the future. The present review attempts to provide an insight into general knowledge available for class Ⅱa bacteriocins and discuss common features and recent findings concerning these substances.
