To identify the key elements and available tools of regional health information resources plamling,the study introduced an innovative I-beam map,aiming to solve the two key questions of what and how to plan The paper covered such issues of planning as what is the present situation of regional health information,how to divide functional categories of regional health information resources,what are included in the business subclasses,which core data are used in the business process,which data to share and exchange,how to regulate such data,how to manage the regulations and make continuous improvement,and how to evolve towards planning standardization discriminatively.The study also drew a midfield line with such seven fields as medical service,maternity and child care,disease control and Drevention,health administration,emergency management,blood management and primary healtheare.This midfield line is used,along with stakeholders,planning process,information flow and planning output make the four quadrants,describing the whole process in the I-beam form.This practice can provide the methodology ofhow to plan,in the hope of guiding regional health information resource planning from theory to practice.

Regional health planning is a leading and scientific management philosophy for healthcare development in the international community.Information resources planning paves the way for scientific development.In the ongoing health reform in China,planning of regional health resources will play a key role by leveraging information technology.From the viewpoints of health information resources and information resources planning,the paper defines the concept of regional health information resources planning in microcosmic perspective.It summarized the five features of public welfare,specificity,imbalance,small channel and low noise,and non-symmetry.Authors compared the five planning modes,namely the community medical information resources mode,the general hospitals as the center of information resource mode,the regional PACS mode,the regional health data resource mode,and the regional medical coordination resources mode.In the paper,the planning is rounded up as four key points,that is,the basic steps of situation assessment and analysis,routine work of health information standardization,the planning should both comply with general rules of information resource planning and characteristics of the health sector,in addition to guidelines of forward-looking concepts.

Objective To investigate the expression and methylation status of HOXA7 gene in human pancreatic cancer cell lines, and to explore the relationship between them.Methods HOXA7 mRNA expression of human pancreatic cancer cell lines BxPC3, CFPAC1, PANC1 and SW1990was detected by RT PCR.Bisulfite sequencing PCR (BSP) and combined bisulfite restriction analysis (COBRA) was used to test promoter methylation status.All the cell lines were treated by 5-aza-2-deoxycytidine (5-aza-dC), and HOXA7mRNA expression, methylation status was detected before and after this treatment.Results HOXA7 mRNA was expressed in BxPC3, CFPAC1 and SW1990, while there was no expression of HOXA7 mRNA in PANC1.HOXA7 promoter methylation rates of CFPAC1, BxPC3, PANC1 and SW1990 were 93.16%, 90.65%,90.09% ,52.30%.HOXA7 promoter methylation rate of SW1990 was significantly lower than those in other 3cell lines ( P ＜0.01 ).After 5-aza-dC treatment, HOXA7 mRNA of PANC1 was expressed again, and HOXA7mRNA of BxPC3 was increasingly expressed;while the expression of HOXA7 mRNA in CFPAC1 and SW1990was not significantly changed after 5-aza-dC treatment.Conclusions The expression of HOXA7 mRNA in BxPC3 and PANC1 was closely correlated with promoter hypermethylation, while there was no obvious relation in CFPAC 1 and SW1990.

Objective To determine the methylation status and expression of Ras association domain family 1A (RASSF1A), and the possible effect between promoter aberrant methylation and pathogenesis of pancreatic cancer. Methods The methylation status of RASSF1A promoter CpG island (CGI) pancreatic cancer cell line BxPC3 was detected in 5 cases of normal pancreatic tissue and 13 pairs of pancreatic cancer tissues (tumor and peri-tumor) by using COBRA (combined bisulfite restriction analysis) and the methylation rate was calculated. The RASSF1A mRNA expression of BxPC3 was compared between pre- and post-treatment of the inhibitor of DNA methyltransferase (5-Aza-2-deoxycitydine, 5-Aza-dC). Results The average methylation rate of RASSF1A promoter CGI was 62.90% in BXPC3, 9.14% in normal pancreas, 53.79% in peri-tumors (TP), and 55.82% in tumors. The methylation rates in port-tumors and tumors were significantly increased when compared with that of normal pancreas (P < 0.01), while there was no significant difference between in peri-tumors and tumors (P > 0.05). After 5-Aza-dC treatting BxPC3 cells, the methylation rates decreased to 42.5% (P < 0. 05) and RASSF1A mRNA expression was enhanced. Conclusions Aberrant hypermethylation of RASSF1A promoter CGI could be considered as an early event in the process of pancreatic cancer and participates in the pathogenesis of pancreatic cancer.
