The US federal government regards health information technology (HIT) as an important action to stimulate growth of the health information economy.To implement HIT,the federal government proposed a tiered plan from organization guarantee,institutional innovation,HIT system design to economy stimulating mechanism,and to health care providers as well.In view of China's HIT development,it is proposed that HIT must proceed with healthcare reform in parallel.Stage-setup by the government,competition among enterprises,and active role of medical service providers constitute fundamental guarantee to ensure HIT go on wheels.Electronic health records of individuals should play key roles in promoting pragmatic and shared medicine health care information system.

Objective　To establish a simple assay for quick scanning of effective agents in growth inhibition and apoptosis induction. Methods　After observing the correlation between cell number and acid phosphatase activity, and between cell apoptosis and acid phosphatase activity, we established a microplate densimetry method to measure the acid phosphatase activity. We also compared the sensitivity with MTT assay and confirmed cell apoptosis by flow cytometry. Results　In two cell lines of cancer (Hep G2 and CBRH-7919 cells), the acid phosphatase activity was correlated well with the cell number, and was directly proportional to the cell number in the range of 0.5×103～0.7×103. The coefficient reached to 0.994. After stimulation of phorbel ester (TPA) for one hour, the acid phosphatase activity rose significantly. In contrast, after the inhibition of cell growth by As2O3, the acid phosphatase activity decreased significantly. The higher the concentration of As2O3, the lower the acid phophatase activity. The acid phophatase activity went down significantly when apoptosis in Hep G2 cells was only 3.98% and no apoptosis in CBRH-7919 cells after 24-hour treatment with As2O3. Conclusions　The acid phophatase activity of cell may be used to measure cell proliferation and apoptosis. Because of the easiness and quickness, acid phophatase assay might be an ideal approach to scan the effective growth inhibitors and apoptosis inducers in a large number of drugs.

ObjectiveTo identify the proteins presented variation during ischemia/reperfusion injury (I/RI) in liver transplantation (LT).MethodsAt Mar.2009,a total of nine liver sample tissues,three samples obtained from each donor liver at three different time points,were studied.The time points were as follows:(1) the time point immediately after donor liver was harvested (T1) ; (2) the time point just before the anastomosis of hepatic artery and potal vein (T2),during this time period the donor liver was kept in ice cold and transported,then back-table prepared,during time from T1 to T2,ischemia injury occurred; (3) the time after donor reconnected to the recipient (T3),during which the donor liver was subjected to reperfusion injury.The three time points represent normal control,ischemia injury,and reperfusion injury respectively.By using method of 2DE-MALDI-TOF and mass-spectrum,the differential expression of these protein at T1,T2,and T3 time point were compared.ResultsFrom the 1580 proteins that were isolated,19 ischemia/reperfusion injury (I/RI)-related proteins that varied markedly from time point T1 to T2 and from time point T2 to T3 were identified.They were metabolic enzyme,molecular chaperone,redoxase,cytoskeleton protein,signal transduction protein,and binding protein,respectively.The character of each protein was further analized based on their functions.ConclusionsFor the first time,we detected the protein related to I/RI during LT.We obtained independent proteomics information of ischemia injury,and reperfusion injury,respectively.Further functional analyses of these proteins may improve the understanding of the critical biological processes during I/RI.Medicine intervention on the I/RI-related proteins may result in improved survival of the recipients.
