AIM: To determine the cut-off value of intercellular adhesion molecule-1(ICAM-1) and assess the correlation of ICAM-1 with clinicopathological features and the prognosis of hepatocellular carcinoma(HCC)patients who underwent surgical ***: We prospectively collected clinicopathological data from 236 HCC patients who had undergone successful hepatectomy. Receiver operating characteristic curve analysis was performed to determine the optimal cut-off value of ICAM-1. Enzymelinked immunosorbent assay was used to measure the concentration of ICAM-1 in 236 serum samples isolated from HCC patients and the stratified analysis was used to compare the serum level of ICAM-1 in different HCC subgroups. Immunohistochemistry was performed to test the expression level of the ICAM-1 protein in76 cases of HCC tissues and their adjacent normal liver tissues(ANLT). The survival probability of HCC patients was estimated using Kaplan-Meier plots and differences between the groups were obtained using the log-rank test. Furthermore, independent indicatorsof the prognosis were acquired using a stepwise Cox proportional hazard model to analyze a series of predictors that were associated with disease-free survival(DFS) and overall survival(OS) in HCC ***: Our findings suggested that ICAM-1promotes HCC metastasis and high serum ICAM-1 is significantly associated with alpha-fetoprotein(AFP)(P = 0.022), clinical tumor-node-metastasis stage(P 684 ng/mL was an independent factor for DFS(HR = 1.643; 95

AIM:To conduct a meta-analysis evaluating theassociation between the peripheral blood neutrophil to lymphocyte ratio(NLR) and the outcome of patients with pancreatic ***:Studies evaluating the relationship between the peripheral blood NLR and outcome of patients with pancreatic cancer published up to May 2014 were searched using electronic databases, including Pub Med, Web of Science, Embase and Ovid.A meta-analysis was performed to pool the hazard ratios(HRs) or odds ratios(ORs) and their 95% confidence intervals(CIs) using either a fixed-effects model or a random-effects model to quantitatively assess the prognostic value of NLR and its association with clinicopathological ***:Eleven studies containing a total of 1804 patients were eligible according to our selection criteria, and combined hazard ratios indicated that high NLR was a poor prognostic marker for pancreatic cancer patients because it had an unfavorable impact on the overall survival(OS)(HR =2.61, 95%CI:1.68-4.06, P =0.000) and cancer specific survival(HR =1.66, 95%CI:1.08-2.57, P =0.021).Subgroup analysis revealed that high NLR was associated with poor OS in patients with mixed treatment(HR =4.36, 95%CI:2.50-7.61, P =0.000), chemotherapy(HR =2.08, 95%CI:1.49-2.9, P =0.000), or surgical resection(HR =1.2, 95%CI:1.00-1.44, P =0.048).Additionally, high NLR was significantly correlated with tumor metastasis(OR =1.69, 95%CI:1.10-2.59, P =0.016), poor tumor differentiation(OR =2.75, 95%CI:1.19-6.36, P =0.016), poor performance status(OR =2.56, 95%CI:1.63-4.03, P =0.000), high cancer antigen 199(OR =2.62, 95%CI:1.49-4.60, P =0.000), high C-reactive protein(OR =4.32, 95%CI:2.71-6.87, P =0.000), and low albumin(OR =3.56, 95%CI:1.37-9.27, P =0.009).CONCLUSION:High peripheral blood NLR suggested a poor prognosis for patients with pancreatic cancer,and it could be a novel marker of survival evaluation and could help clinicians develop therapeutic strategies for pancreatic cancer patients

To better know FM （Fusarium moniliforme） induced genes in maize ear rot, GO （gene ontology） method was performed to analyze detail physiological functions in the defensive response after pathogen infection. This gene annotation system was widely used to investigate large numbers of genes involving in real active role or regulator in cell response. First of all, differentially expressed genes were isolated by using genechip platform at 96 h post-inoculation with FM in maize inbred Bt-1. In total, 482 differentially expressed unique genes were screened out in inbred Bt-1 when compared to mock-inoculated bract tissues. Then, each gene was annotated to define functional class by GO method. Finally, these large FM-responsive genes with significant differentially change were sorted into cellular component, molecular function and biological process with complicated network by molecular annotation system. The demonstrated information in the GO analysis could provide another view for understanding the molecular mechanism and indicate a deeply complicated network with gene function underlying disease development in the host tissue. The findings in this study provide important bases to probe the molecular processes, the alteration of metabolism and the immune mechanism upon the FM infection in maize.

Chitinases play an important role in regulating plant growth and development, especially defending themselves from fungal pathogens. It is important to do the biological analyses in crops. In this study, the result showed that the chitinases were distributed into the whole genome in rice, and nearly the whole genome in maize expect for Chromosome 9. The clustering results showed that one out of three chitinases from maize and rice belonged to new groups, which were separated from those in the conformed Classes I-VII. The identification of most amino acid sequences was very low among the chitinases from rice and/or maize. It was inferred that the chitinases with different functions were relatively stable during plant evolution. The relationship of chitinases expression between leaf blade and anther was positively significant in maize, but not significant in rice. Additionally, the ratio of chitinases with up- or down-regulated expression in sensitive maize under Fusarium moniliforme inoculation was different from that in sensitive rice under Magnaporthe grisea inoculation. It might be result from different tissues infected by different fungi. The number of chitinases from resistant maize was less than that from sensitive maize, which inferred that the resistant pathways on F. moniliforme should be not only chitin induced Pathogen-associated molecular PTI （patterns-triggered immunity） pathway, but also might include other PTI pathways that improve tolerance to F. moniliforme. The analysis of expression pattern of chitinases from maize and rice under fungi inoculation will be contributed into further research on the defense mechanism of fungi in crops.
