We have previously reported that the maximal inferior vena cava(IVC) diameter during quiet expiration(IVCe) measured by ultrasonography correlates well with the amount of body fluid, especially the circulating blood volume[1] and proposed using the criteria of IVC diameter to determine dry weight(DW) in anuric hemodialyzed (HD) patients: standard IVCe of pre-and post-HD are (14.9±0.4) and (8.2±0.3) mm, respectively[2]. However, the same post-HD IVC criterion should not be applied to nonoliguric HD patients because it could result in rapid deterioration of residual renal function due to forced dehydration. Although the biochemical DW marker plasma atrial natriuretic peptide (ANP) is useful to evaluate hypervolemia but not hypovolemia,both hyper-and hypovolemia can be detected by IVC measurement.……展开更多

Since BW and stature as well as gender and age were not considered to be determinant factors of the IVC diameters, these factors were not accounted for in evaluating the IVC diameters in HD patients. The IVC diameters of stable anuric HD patients are shown in Table 2. In agreement with our previous observation [7-9] ,the reduction of BW from (51.7±12.6) to (49.3±12.6)kg by ultrafiltration during HD resulted in a significant (P<0.0001)reduction of the IVCe and IVCi from (14.9 ± 3.2) to (6.8±1.9)mm and (5.2±4.2) to (0.1±0.3) mm,respectively. Thus,CI values before and at the end of HD were calculated as (0.68±0.24) and (0.98±0. 05), respectively (P<0.0001).

By dynamic reaction with fixed anti-human CD4 antibody, SPR could offer significant signals to distinguish hemodialyzed patients from the healthy controls within 200 s after the cell injection in respect of either rising speed or maximum binding capacity （p 〈 0.01）. The ratio method is also used to exclude the non-specific adsorption. The percentage of hemodialyzed patients＇ CD4＋ T ceils against the healthy control is 69 ± 18%. The most attractive of the present method is its ability to detect the intact and label-free lymphocytes, and further to detect the subpopulations, or proteins secreted by the desired lymphocytes subset.展开更多
