Background Goldmann applanation tonometry (GAT) is a gold standard of intraocular pressure measurement.But its utilization iS limited because of its complexity and high requirement of cooperation.iCare rebound tonometer (iCare RBT) is a new type of applanation tonometry,and its accuracy and safety in clinical application need to be evaluated.Objective Present study was to investigate the reproducibility and tolerability of iCare RBT and its measurement agreement with GAT over a wide intraocular pressure (IOP) range. Methods The IOP were measured in bilateral eyes of 36 glaucoma and glaucoma suspect patients by 2 examinees with iCare RBT at the 1-minute interval to assess the interobserver reproducibility.Then the IOP of both eyes from 56 Subjeets and other 52 subjects were separately measured twice for each by two operators with iCare RBT for the evaluation of intraobserver reproducibility.Finally.IOP of 182 eyes of 92 glaucoma and glaucoma suspect patients was obtained by examiner 2 with RBT first and examiner 1 with GAT subsequently at a 2.minute interval in a masked fashion to perform an agreement evaluation of two readings by using Bland-Ahman method.The tolerance of subjects to iCare RBT measurement were surveyed.Oral informed consent was obtained prior to the IOP measurement. Results Concerning the iCare RBT readings.interobserver correlation coefficients were 0.937 in the right eye and 0.887 in the left eye.Intraobserver correlation coefficients of examiner 1 were 0.986 in the left eyes and 0.969 in the fight eyes.And those of examiner 2 were 0.990 and 0.979.Mcan values of iCare RBT readings and GAT were(18.74±8.36)mmHg and(19.33±8.20)mmHg and the mean difference values(iCare-GAT)was(-0.59 4±2.60)mmHg with the 95%confidence interval of -5.80-4.60 mmHg.The correlation coefficient between two modalities of IOP measurement WaS 0.95 1.No severe pain and discomfort were complained in all the subjects during or after measurement of iCare RBT. Conclusion iCare RBT has good interobserver and intraobserver reproducibility and good tolerance.It was proved that this is a good correlation between iCare RBT readings and GAT readings.

The aim of this study was to investigate the biological characteristics of human bone marrow mesenchymal stem cells from bone marrow of different age donors. The experiments were divided into four groups by donors age, group A represented MSC derived from fetal bone marrow, group B represented MSC derived from bone marrow of 0-20 years old donors, group C represented MSC derived from bone marrow of 20-40 years old donors and group D represented MSC derived from bone marrow of donors older than 40. The growth, purification, proliferation and multipotential abilities of MSC in 4 groups were observed and their immunophenotypes were determined by flow-cytometry. The level of cytokines (IL-6, SCF, FLT-3L, SDF-1 and TGF-beta1) were assayed by ELISA method. Cell cycles were analyzed to show the proliferation index (PrI). MSCs derived from bone marrow of 4 groups were injected subcutaneous into NOD/SCID mouse to observe the safety. The results showed that different age donors bone marrow all gave rise to MSC. These cells were similar in morphology, antigenic phenotype, differentiation potential and cell cycle. The primary culture time of group B was shorter than other groups. The duration of passage 1 (P1) was 5.5 days, and the duration of P10 was 33 days, after P10 culture, (5.19 +/- 2.15) x 10(10) MSCs were obtained from 8 x 10(6) MNC of this group. The primary culture time of groups A, C, D were longer, the duration of P1 were 15, 7 and 13 days for group A, C and D respectively, and the duration of P10 was 50, 60 and 72 days for group A, C and D, respectively. After P10 culture, (4.98 +/- 2.08) x 10(10), (1.86 +/- 0.47) x 10(10), (0.64 +/- 0.22) x 10(10) MSCs were obtained from 8 x 10(6) MNC of group A, C and D respectively. The morphology of MSC of group A was longer and slender. The ability of expansion decreased after P15 for A group, P10 for B group and P8 for C and D groups. The levels of SCF, FLT3-L, IL-6 and SDF-1 in group B were higher than other groups. Karyotype analysis showed that MSCs from 4 groups were normal, and tumor-like tissues were not developed after cultured MSCs were inoculated in NOD/SCID mice. It is concluded that there was relationship between age and the biological characteristics of human bone marrow mesenchymal stem cells. For clinical use, especially in hematopoietic stem cell transplantation (HSCT), 0-20 years old donors were perfect MSCs donors who can provide sufficient MSCs in relatively short times. MSCs of group B can be used as stem cell source because the biological characteristics of MSCs of groups B are superior to that of other groups.

The effect of CYP3A4*18B and CYP3A5*3 on concentration/dosage x body surface area ratios (C/D'), adverse effects and acute rejection of tacrolimus in renal transplant patients were investigated. The CYP3A4*18B genotypes of 227 renal transplant patients were determined by PCR-RFLP method. The differences of C/D' ratios, adverse reactions and acute rejection were compared among all of the genotype groups treated with tacrolimus. The frequencies of CYP3A4*18 and CYP3A5*3 alleles in renal transplant patients were 30.8% and 74.2%, respectively. No significant association was found between the C/D's of tacrolimus and CYP3A4*18B genotypes when they were classified by two CYP3A5 genotypes (P > 0.05). While after the effects of CYP3A4*18B genotype were eliminated, the C/D' ratio of tacrolimus in patients with CYP3A5*1/*1 and *1/*3 genotype group was significantly lower than those with CYP3A5*3/*3 genotype groups (P < 0.01). There is no significant difference in adverse effects and acute rejection among different genotypes (P > 0.05).

BACKGROUNDImmunological sensitization remains a major problem following renal transplantation. There is no consensus for the management of sensitized renal allograft recipients. The patients become tethered to dialysis while waiting for compatible donors. This study was designed to evaluate the efficacy and safety of preoperative single-bolus high-dose antithymocyte globulin (ATG) as induction therapy in sensitized renal transplant recipients.

METHODSA total of 56 patients were divided into two groups according to the level of panel reactive antibody (PRA): non-sensitized group (PRA < 10%, n = 30) and sensitized group (PRA > or = 10%, n = 26). The characteristics of the recipients and donors were comparable between the two groups. Mycophenolate mofetil (MMF, 1 g) or ATG (iv. 9 mg/kg) were given preoperatively in the two groups as induction therapy. After the transplantation, the patients were treated with standard triple therapy regimen consisting of tacrolimus (FK-506) or cyclosporine A, MMF, and prednisolone. Acute rejection (AR) and infection episodes were recorded and renal function was monitored during a 12-month follow-up. Chi(2) test and t test were used to analyze the data.

RESULTSDuring the follow-up, 6 patients (20.0%) suffered AR episodes in the non-sensitized group and 4 (15.4%) in the sensitized group (P = 0.737); 8 patients (26.7%) experienced 11 infection episodes (average, 1.4 episodes per infected patient) in the non-sensitized group, and 6 (23.1%) experienced 10 infection episodes (average, 1.7 episodes per infected patient) in the sensitized group (P = 0.757, 0.890). The safety of the drugs, which was assessed by the occurrence of side effects, was comparable between the two groups. The hospital stay was 13 - 25 days (mean, 16.7 +/- 3.3) in the non-sensitized group and 14 - 29 days (mean, 16.2 +/- 3.1) in the sensitized group, respectively (P = 0.563). No delayed graft function (DGF) was observed in all the patients. Both the 12-month actuarial patient and graft survival rates were 100% in the two groups.

CONCLUSIONPreoperative single-bolus high-dose ATG is an effective and safe induction therapy yielding acceptable acute rejection rate in sensitized renal transplant recipients.
