Objective To study the prothrombotic state ,the factors leading to this status,and its relation-ship with the risk of cardiovascular disease in impaired glueese tolerance (IGT) patients. Methods The patients were divided into 4 groups : ①20 control subjects, ②38 patients with IGT, ③20 patients with diabetes only,④31 with diabetes and coronary heart disease. The vWF, throbomodulin, protein C, protein S, plasminogen activator inhibi-tor 1 were measured by ELISA. Results ①)There was statistical difference between IGT and controls in vWF, activi-ty of PC and PAI-1 (P <0.01 ,respectively). ②There were different factors that probably lead to the prothrombotic status among patients with IGT and diabetes. ③There were statistical differences among IGT, diabetes and diabetes with coronary heart disease in vWF, activity of Protein C. There were statistical difference among IGT , diabetes and diabetes with Coronary heart disease in PAI-1 (P < 0.05,respectively). Conclusion ①There is the prothrombotic status in the patients with IGT, similarly to those with diabetes.② IGT has the similar prethrombotic status as diabe-tes, So IGT could be considered as the predromal stage of diabetes, because of some continuity in the progress. Mean-while,it still has some different specialties. ③The abnormality of the system of endothelium, anti-coagulation and fi-brolysis in the patients of IGT is similar to those with diabetes. These variations might have the similar risk of cardio-vascular disease with the diabetes.

Objective Through the research of the disposal of clinic laboratory result information,the paper explore the methods of building up laboratory's online management system and network information system.Methods This project began with the analysis of the need of laboratory and applies computer to simulate the manual disposal process.The system framework was separated into many sub parts according to its function.VB,etc were used to program.Results The project has been gained successfully in the online managemert of two analyzers and the management of data network consisting of three laboratories.Conclusion The project has established a practical and reliable in-formation management system which matches the work mode in clinical laboratory and has novelty functions.

Objective To investigate the levels of serum vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) in patients with non-small cell lung cancer(NSCLC) and relationships with c1inicopatho1ogica1 characteristics and their clinical significance. Methods The concentrations of serum VEGF and bFGF were detected by enzyme-linked immunosorbent assay(ELISA) in 40 patients with NSCLC before and after chemotherapy. Results The level of serum VEGF in patients with Ⅳ stage NSCLC was significantly higher than that of Ⅲ stage(P

Objective To investigate the state of drinking water defluorination project in Dagang district and study urinary fluoride levels and detect dental fluorosis of children aged 8 to 12, and to provide scientific basis for prevention and control of fluorosis. Methods Five defluorination projects in rural streets (towns) with highfluoride water and 2 urban water supply projects were choosen to investigate the running status in Dagang district Tianjin in 2009. Five rural and 2 urban schools were choosen to select 100 children aged 8 to 12 (for gender, age matched) in each primary school to study urinary fluoride levels and detection of dental fluorosis. Results A total of 66 defluorination projects in 73 villages were surveyed, among which 61 projects actually worked normally with using rate 92.4%(61/66). Water qualification of all projects could not be ensured due to direct project managers'lack of necessary expertise. In 2009, water qualification rate were 39.3%(24/61 )among the project normally used,with highlighted problem of biological pollution. A total of 490 children aged 8 - 12 in 5 rural towns were surveyed,dental fluorosis rate were 90%(441/490), and dental fluorosis index were 1.82. A total of 207 children aged 8 - 12in 2 urban areas were surveyed, the detection rate of dental fluorosis was 49.8%(103/207), and dental fluorosis index were 0.86. The urinary fluoride level of 230 children aged 8 - 12 in the 5 villages were surveyed. The Range of geometric mean of urinary fluoride were 1.82 - 2.70 mg/L. The urinary fluoride of 102 children aged 8 - 12 in the 2 urban area were surveyed. The Range of geometric mean of urinary fluoride were 1.53 - 1.72 mg/L. Conclusions There was phenomenon of high coverage, low utilization rate and less water consumption in the villages of Dagang district, Tianjin drinking water defluoridation projects, thus the health effects of the projects was minimum.Significant health effects is found in the defluorination projects in the urban areas with high coverage and high utilization rate. Studying new water improvment methods and new forms of water supply system is urgent for solving the problems met in the ineffective water defluorination project.

OBJECTIVETo evaluate the effects of basic fibroblast growth factor(bFGF) on proliferation of periodontal fibroblast-like cells in vivo.

METHODSA U-shaped osseous defect was produced on the buccal side of the mesial root. Four posterior teeth were conducted in four quadrants. Each quadrant included 4 groups: control, bFGF, expanded polytetrafluoroethylene(ePTFE) membrane, bFGF + ePTFE. Each time the 4 teeth sites in one quadrant were operated weekly and each dog experienced 4 times of operations. Bromodeoxyuridine(BrdU) was injected 1 hour prior to sacrificing the dogs at 4 weeks after first surgery. Immunohistochemical method was applied to count the BrdU-labeled fibroblast-like cells.

RESULTSThe number of BrdU-labeled cells reached the maximum at the 2nd week among all groups and then, decreased with time. Both bFGF and bFGF + ePTFE treated group had significantly more BrdU+ cells than remained control or ePTFE groups (P < 0.05) at 1st, 2nd weeks after surgery.

CONCLUSION2 weeks after periodontal surgery is active phase of proliferation of periodontal fibroblasts. bFGF enhances fibroblast proliferation in early periodontal wound healing, and in turn accelerate periodontal regeneration.

To investigate the effects of interferon alpha-2b on proliferation and apoptosis in HL-60 cells, HL-60 cells were cultured in different concentrations of IFN alpha-2b. The morphologic changes were observed by Wright's and acridine orange (AO) and ethidium bromide (EB) staining respectively. Inhibition of proliferation was detected by MTT. Expression of CD13(+) was checked by indirect fluoroimmunoassay. The results showed that apoptosis rate of HL-60 cells assayed by the above-mentioned two methods was (51 +/- 2)% and (78 +/- 3)% respectively and OD(570) values of proliferation inhibited were 1.8 +/- 0.1 and 1.0 +/- 0.1 respectively when the concentrations of the IFN(alpha-2b) were 500 and 10,000 U/ml in culture for 48 hours. Morphology and count of CD13(+) cells were changed. CD13(+) cell expression rate was (62 +/- 2)% and (30 +/- 3)% respectively when the concentrations of the IFN(alpha-2b) were 500 and 10,000 U/ml in culture for 48 hours. It is concluded that IFN(alpha-2b) can enhance the apoptosis of HL-60 cells, inhibit their proliferation, promote their maturation and differentiation.
