[Objective] To investigate the expression of NF-κB and IL-lra in gastric cancer, and to explore their correlation with the clinicopathological parameters and prognosis of gastric cancer (GC). [Methods] Expression of NF-κB and IL-1ra was detected by immunohistochemistry in tissue microarry of 359 cases of GC. [Results] The expression rates of NF-κB in the patients with metastasis of lymph node, TNM Ⅲ-Ⅳ stage, and poorly differentiated of histology were 80.2%, 80.0%, and 79.2%, respectively. The expression rates of IL-1ra in the patients with tumor size ≤3 cm, early stage, non-metastasis of lymph node, and TNM Ⅰ-Ⅱ stage were 61.7%, 75.0%, 66.4%, and 61.9%, respectively. The 5-year survival rate of the cases with non-expressed NF-κB was statistically higher than that of the cases with expressed NF-κB(P=0.036). The 5-year survival rate of the patients with negative expression of NF-κB and positive expression of IL-1ra was statistically higher than the others (P=0.021). [Conclusions] NF-κB is the adverse predictors of prognosis of gastric cancer. IL-1ra maybe play a protective role in early gastric cancer stage, but it is necessary to study deeply and get more evidences.

Abstract：Pyroptosis is a new programmed cell death mode，which plays a dual role in the pathogenesis of hepatocellular carcinoma（HCC）. On the one hand，inflammasomes causing pyroptosis and inflammatory mediators released during cell pyroptosis promote the occurrence and development of HCC；On the other hand，pyroptosis can inhibit the proliferation， metastasis and invasion of HCC cells. With the deepening of research，the role of pyroptosis in HCC has become increasingly prominent. This paper reviews the potential effects of pyroptosis on the progression of HCC and its role in anticancer therapy. Keywords：Pyroptosis；Inflammasome；Hepatocellular carcinoma（HCC）；Gasdermin D（GSDMD）

Objective Using flowing injection hydride generation atomic fluotometric method(FI-HG- AFM)to detect the whole blood selenium content.Methods A series of standard selenium(1,2,4,6,8.10μg/L) were dectecte by FI-HG-AFM,and the precision and accuracy of the method were observed.The selenium contents of 89 blood samples were detected by FI一HG-AFM and 2,3-diaminonaphthalene fluorometric method(DFM) respectively,and the correlation of two methods Was analyzed.Results The detection limit and recovery rate of FI-HG-AFM were 0.138μg/L and 96.4%,respectively.The relative standard deviation(RSD)was maximized at 1 μg/L(4.406%).The RSD diminished along with the increase of the concentration,and it declined to 0.512%at 10 μg/L.There wag no significant difference(t=1.7878,P>0.05)between the result8 of FI-HG-AFM[(45.9± 14.5)μg/L]and DFM[(47.5 ±13.3)μg/L],and the two methods were in highly positive correlation(r=0.8143,P< 0.01).Conclusions The whole blood selenium content call be rapidly and exactly detected by FI-HG-AFM,and the method are highly consistent with DFM.

OBJECTIVE: We intended to analyze the credibility judgment in written forensic psychiatric reports of child sexual abuse registered in Southern Taiwan. METHODS: Ninety-six cases of child sexual abuse between August 2010 and October 2017 encountered in two hospitals were analyzed. The results in these reports were categorized into credible and non-credible. We identified the factors that distinguished between the two groups in bivariate analyses using chi-square test. A binary logistic regression analysis was performed to determine whether the factors that significantly correlated in the bivariate analyses were independent predictors of credible judgments. RESULTS: Among 96 cases, 70 (73%) were judged as credible. Consistent testimonies of children (odds ratio=40.82) and multiple abuse events (odds ratio=6.05) were positive variables independently related to the sexual abuse allegations judged as credible. CONCLUSION The number of allegations judged as credible in this study was slightly higher than that reported in other studies. Our findings about predictors for credible cases are not in line with those reported previously. Due to the differences in resources of the cases and backgrounds of the evaluators among multiple studies, direct comparisons with previous studies must be treated with caution.

OBJECTIVETo construct E1-deletion and replication-defective human type 5 recombinant adenovirus vector and to study the effect of p16INK4a on proliferation and aging of A549 cells.

METHODSp16INK4a cDNA was cloned into pAdCMV to construct recombinant pAdCMV p16INK4a, which was co-transfected into 293 cell together with pJM17. The recombinant p16INK4a adenovirus (Ad-p16INK4a) was generated by homologous recombination and identified with duplex PCR. Lung cancer cell A549, which has a homozygous deletion of p16INK4a gene, was infected with the prepared Ad-p16INK4a virus. X-gal staining and TRAP-ELISA were used for detecting senescence-associated beta-galactosidase and telomerase activities in A549 cells.

RESULTSImmunohistochemical staining and Western blot indicated that p16INK4a gene was transferred into A549 cell with more than 95% efficiency by recombinant adenovirus and p16INK4a protein was expressed at a high level- p16INK4a could markedly inhibit growth of A549 cells, induced expression of senescence-associated beta-galactosidase and suppressed telomerase activity in A549 cells.

CONCLUSIONRecombinant adenovirus vector could efficiently mediate transfer and expression of foreign genes in human cell and could be used for gene immunization and gene therapy; p16INK4a could inhibit A549 cell growth and induce its replicative senescence.
