Objective: To screen the Hub genes associated with the occurrence and development of esophageal squamous cell carcinoma (ESCC) and to analyze their biological functions by using various bioinformatics analysis tools. Methods: ESCC chip profile GSE100942 from GEO database was used as study subject; GEO2R tool was used to analyze the data and to screen the differentially expressed genes (DEGs), and the bioinformatics tools (DAVID, String, Cytoscape) were further used to construct protein-protein interaction (PPI) network and identify the key Hub genes. GO and KEGG were used for the biological function enrichment analysis. In the meanwhile, MiRDB was applied to identify the miRNAs that might regulate Hub genes and to construct Hub gene–miRNA network. Importantly, the expression of DEGs and the patient survival were verified by the GEPIA analysis tool. Results: By analyzing GSE100942 database, a total of 1229 DEGs with difference of 2 times and 223 DEGs with difference of 4 times were screened out. In addition, 20 Hub genes, which were all up-regulated in ESCC tissues, were also identified. The functional enrichment analysis showed that these DEGs were mainly enriched in cancer related pathways and involved in cell division and mitotic nuclear division. Among those 20 Hub genes, DLGAP5, BUB1B, TPX2, TTK, CDC20, CCNB2, AURKA and DEPDC1 were identified as 8 key Hub genes that related with ESCC, and involved in many important biological processes, such as cell proliferation, cell cycle and signal pathway. Five Hub genes, CEP55, ECT2, NEK2, DEPDC1 and NUSAP1, were identified to be highly regulated by the miRNA regulatory network. Conclusion: Microarray combined with bioinformatics can effectively analyze the DEGs associated with the occurrence and development of ESCC. The identification of the 20 Hub genes and the 8 key Hub genes can provide theoretical guidance for further research on the molecular mechanism and molecular marker screening of ESCC.

Angiotensin I-converting enzyme (ACE) inhibitory peptides have been shown to have antihypertensive effects and have been utilized for physiologically functional foods and pharmaceuticals. The ACE inhibitory ability of a hydrolysate is determined by its peptide composition. However, the peptide composition of a hydrolysate depends on proteolytic enzyme and the hydrolysis conditions. In this study, the effect of process conditions on the ACE inhibitory activity of rice dregs hydrolyzed with a trypsin was investigated systematically using response surface methodology. It was shown that the ACE inhibitory activity of rice dregs hydrolysates could be controlled by regulation of five process conditions. Hydrolysis conditions for optimal ACE inhibition were defined using the response surface model of fractional factorial design (FFD), steepest ascent design, and central composite design (CCD).

Objective To study the histological classification,clinical stage,histological grade and prognosis of renal cell carcinoma by analyzing the records of the patients in Shanghai Renji hospital. Methods A consecutive series of 435 patients with renal cell carcinoma between 2003 and 2005derived from the renal cancer database were reviewed clinically and pathologically.The 1997 version of WHO histological classification for renal epithelial tumor,the 2002 version of AJCC clinical TNM staging system and the 1982 version of Fuhrmaffs system for nuclear grade were used.By survival analysis of 57 cases with advanced renal cell carcinoma using Kaplan-Meier method prognostic factors were confirmed using logrank test. Results Of a total 435 patients,cases were classified into 10(accounting for 2.4%of renal cell tumors)hereditary renal cancer in VHL disease,372(85.5%)clear cell renal cell carcinoma(CCRCC),13(3.0%)papillary renal cell carcinoma(PRCC),18(4.1%)chromophobe renal cell carcinoma(CRCC),4(0.9%)oncocytoma,4(0.9%)carcinoma of the collecting ducts of Bellini(CCDB),and 14(3.2%)renal cell carcinoma unclassified.There were 335(77%)patients undergone radical nephrectomy,74(17%)nephron sparing surgery and 26(6%)others,such as palliative nephrectomy.The patients with VHL disease come from 5 Chinese kindred and all had bilateral clear cell renal cell carcinomas and multifocal renal cysts.There were 7 paients of stage Ⅰ and 3 cases of stage Ⅱ and 6 cases of grade Ⅰ and 4 cases of grade Ⅱ.Genetic test revealed that all patients had VHL gene mutation.4 patients had recurrence while no evidence of local advance and distant metastasis were found during a mean of 28.6 months.Patients with chromophobe RCC are all of stage Ⅰ and 5 cases of grade Ⅰ and 13 cases of gradeⅡ.All patients are alive without recurrence or metastasis during a mean of 19.8 months.Collecting ducts RCC all presented with stage Ⅰ but grade Ⅲand with the median survival only 11.3 Months.Of clear cell and papillary RCC,260(67.6%),64(16.6%),32(8.3 %),29(7.5%)were stage Ⅰ,Ⅱ,Ⅲand Ⅳ,and of stage Ⅰ patients 147(38.2%),113(29.4%)were T1a and T1b respectively.124(32.2%),219(56.9%),40(10.4)and 2(0.5%)were grade Ⅰ,Ⅱ,Ⅲ,Ⅳ,respectively.Median survival of 57 advanced RCC is 16.0±1.3months,1-year survival is 55%,and 2-year survival is 31%,respectively.By using logrank test,clinical stage(<0.01),tumor size(<0.01),lymphadenopathy(<0.01),metastasis(<0.01)and tumor grade(<0.01)were anatomical and histological prognostic factors for advanced RCC. Coneluslons Different RCC subtypes have different clinical course.The RCC patients in VHL disease have VHL gene mutation and the tumors are often multifocal,bilateral,clear cell type with a low stage and grade which often recurrence but without metastasis.Chromophobe RCC may have a favorable prognosis but collecting duct RCC poor prognosis.In anatomical and histological level,clinical stage,tumor size,lymphadenopathy,metastasis and tumor grade are prognostic factors of survival for advanced RCC.
