0.05).Conclusion:People adjust the immunological function of B cells to normal level in blood donation plastochrone.These undoubtedly provide powerfully experimental data on the enlistment of volunter blood donation.

Objective To investigate the clinical value of PET-CT in aiding CT guided percutaneous puncture biopsy for lung mas-ses.Methods The retrospective data were analyzed including 5 7 patients with lung masses who underwent CT guided percutaneous puncture biopsy combined with PET-CT (regarded as a research group)and other 75 similar patients with single CT-guided biopsy (control group).In two groups,it was divided with malignant,suspicious malignant,can not be diagnosed,inflammatory,benign by pathological findings,and was contrasted with the surgical pathology or final clinical results.To calculate sensitivity,specificity and accuracy of diagnosis for cancer through two puncture method.Recorded complication for pneumothorax and bleeding in two groups .Be compared analysis using the 2 test.Results In study group,it was higher for the diagnosis of malignancy sensitivity, specificity,accuracy.There were 96.3% (52/54),100.0%(3/3)and 96.5%(55/57)in research group,while those were 88.4%(61/69),83.3% (5/6)and 88.0% (66/75)in the control group,respectively.And no statistically significant.Between research and the control group,there was a significantly statistical difference in the rate of twice punctures in one mass (χ2= 10.122,P=0.001).Between the two groups,there was no statistically significant difference in the pneumothorax rate and the hemorrhage rate. Conclusion PET-CT in aiding CT-guided lung biopsy improves the sensitivity,specificity and accuracy of diagnosis.

This retrospective study was performed to determine the ranges of the sodium gradient (SG) between the dialysate sodium concentration (DNa) and serum sodium concentration (SNa) in hemodialysis (HD) patients and to examine the relationships between HD parameters over a 1 year period. Fifty-five clinically stable HD patients, who had been on HD >2 years were enrolled. Monthly HD [ultrafiltration (UF) amount, systolic blood pressure (SBP), frequency of intradialytic hypotension (IDH)] and laboratory data were collected and 12-month means were subjected to analysis. The SG was calculated by subtracting SNa from prescribed DNa. Mean SG values were 1.5+/-3.3 (range -5.6~9.1). SG was positively related to DNa and the frequency of IDH. A higher SG was associated with larger UF amounts and SBP reduction during HD. The percentages of patients with a SG > or =3mEq/L increased as DNa increased. On the other hand, SG was not found to be associated with SNa or pre-HD SBP. DNa appears to cause a significant increase in SG, and this seems to be related to HD parameters, such as, UF amount and IDH.
