OBJECTIVE:To explore the clinical role of two-hour(C2)of CsA in allogeneic hematopoietic stem cell transplantation.METHODS:The whole blood CsA concentration of 9 patients of C0 and 12 of C2 were determined by FPIA method . RESULTS: The satisfactory immunosuppressive concentration was found as follow: C0 was 200～400 ?g?L-1and C2 was 500～700 ?g?L-1.Both C0 and C2 could predict the acute rejection and side-effects,but C2 is more effective.CONCLUSION:The factors that affect the whole blood concentration of CsA were complex. CsA blood concentration monitoring can be used to guide rational use of CsA,but C2 is more effective than C0.

OBJECTIVE:To establish a HPLC-chiral stationary phase(CSP) for separating the enantiomers of lactic acid and determining the optical purity of lactic acid.METHODS:Lactic acid samples of different optical purity were determined by HPLC-CSP vs.optical rotation method.The enantiomers of lactic acid were separated on Chirex 3126(D)-penicillamine chiral column.The mobile phase consisted of copper sulfate solution-isopropyl alcohol (85∶15) at a flow rate of 0.6 mL?min-1.The detection wavelength was set at 254 nm.RESULTS:A baseline separation of the enantiomers of lactic acid was achieved with a separation factor of greater than 1.2.The calibration curve was linear in the range of 0.75～48.24 mg?mL-1 (r=0.999 3),RSD=1.21%.The determination results determined by HPLC-CSP were similar to those determined by optical rotation method.CONCLUSION:The established method is simple,reliable in results and reproducible,and it is applicable for the separation of the enantiomers of lactic acid and determination of the optical purity of lactic acid.

Objective To investigate quality of life and its influencing factors among elderly women with urinary incontinence(UI) living at nursing homes in Beijing. Method A randomized method was used to select six districts in Beijing. All the nursing homes in these 6 districts were included in our study,642 eligible elderly women participated in the survey. Quality of life of 244 women who were identified with different type UI were assessed. Bivariate analysis and multiple analysis were performed. Results The average score of quality of life was 8.5 ± 6.6. Scores of social embarrassment, activity & limiting behavior, psychosocial impacts were 1.8 ± 1.4,4.0 ± 3.5 and 3.3 ± 2.7 respectively. In bivariate analysis, significant differences were found by type of UI, severity of UI,course of UI, health condition, income level and self-care ability. In multiple analysis after adjustment of other variables, UI course≥5 years and inability to take care of herself were risk factors of quality of life.Conclusion Quality of life of elderly women with UI is poor, specific nursing and treatment should be conducted.

BACKGROUND: As the end product of lipid peroxidation, malondialdehyde (MDA) content can be used for assessment lipid peroxidation injury.Glutathione peroxidase (GSH-Px) acts as a free radical scavenger. Currently the effect of static magnetic field on the organism, whether positive or negative, has not been elucidated.OBJECTIVE: To study the effect of static magnetic field on anti-oxidation capacity of mouse hepatic tissues and its intensity dependence for producing such effects.DESIGN: A controlled comparative experiment.SETTING: Laboratories of Medical Physics and Biochemistry of Jiangsu University.MATERIALS: The experiment was conducted in the Laboratories of Medical Physics and Biochemistry of Jiangsu University from January to December 2003. Totally 30 mice of either sex weighing 18-20 g were selected and subjected to magnetic filed exposure using a self-designed ferrite magnet apparatus.METHODS: The mice were equally randomized into normal control group and 4 exposure groups exposed to magnetic field of (24.6±4.2) mT,(42.0±2.1) mT, (63.5±3.0) mT, and (85.1±2.9) mT, respectively. The mice in the 4 exposure groups were exposed to static magnetic field of the specified intensity for 2 hours twice a day, while those in the normal control group were subjected to the sham exposure apparatus without magnetic field at scheduled time points every day. After 15 days of exposure, the mice were sacrificed and the GSH-Px activity and the MDA content in the hepatic tissue were assayed.MAIN OUTCOME MEASURES: GSH-Px activity and MDA content in hepatic tissue of the mice.RESULTS: Thirty mice entered the final analysis without losses. MDA content in (24.6±4.2) mT and (42.0±2.1) mT groups were obviously lower than that in the normal control group [(12.70±0.53), (12.96±0.72), and (17.62±0.91) μmol/g, respectively, F=10.4, 9.89, P ＜ 0.01]. The GSH-Px activity in the hepatic tissue in (24.6±4.2) mT and (42.0±2.1) mT groups were obviously higher than that in the normal control group [(143.36±8.34),(150.69±12.00), (87.51±11.34) μkat/g, respectively, F=10.0, 11.3, P ＜ 0.01].CONCLUSION: Static magnetic field of appropriate intensity can lower MDA content and enhance the GSH-Px activity in the hepatic tissue of mice, and may also improve the activity of antioxidase and reduce the production of lipid peroxidation to diminish the consequent injuries and delay the aging process.

A multi-stage stratified sampling method and a self-designed questionnaire were used to evaluate the prevalence of conjunctivitis symptoms and associated factors among the Beijing residents.In total,12 890 residents aged over 18 years were recruited from 6 districts.The reported prevalence of conjunctivitis symptom at the last years was 1.60％.Self-reported health condition and personal health behaviors were risk factors associated with conjunctivitis among adult Beijing residents.No significant difference existed between different districts,age groups,educational levels,gender and races.Conjunctivitis symptom among Beijing residents was related with health condition and health behaviors.More measures should be taken to cultivate the health model of behaviors.
