? AlM: To compare the two methods for the measurement of glaucoma patients' intraocular pressure ( lOP) between Goldmann applanation tonometer ( GAT) and non-contact tonometer ( NCT) and find the laws of the two methods.?METHODS: The lOP of 108 glaucoma patients ( 206 eyes) were measured by GAT and NCT respectively.?RESULTS: ln 108 glaucoma patients, the average lOP of 206 eyes was 29. 77 ± 10. 27mmHg by GAT and 24. 59 ± 8. 58mmHg by NCT. There was significant difference between GAT and NCT (P<0. 01). The higher of lOP, the difference between GAT and NCT was greater.?CONCLUSlON: The measurement results with NCT were lower than that of GAT. The higher of lOP, the difference between GAT and NCT was greater. lt's better to measure lOP by GAT for the glaucoma patients, in order to avoid the misdiagnosis and mistreatment of glaucoma.

OBJECTIVETo investigate the effect of aluminum chloride on dissociated Ca(2+) in hippocampus neuron cells in mice and the relationship to the learning and memory.

METHODSMale ICR mice in the three intoxicated groups were administered with the double distilled water containing AlCl(3) (10, 50, 300 mg.kg(-1).d(-1)) while those in the control group were administered with the double distilled water for 100 days. The methods of behavior toxicology such as Morris swim maze were used for studying the effect of aluminum chloride on the changes of learning and memory in mice. With calcium sensitive fluorescence indicator Fura-2 as the fluorescent probe, the influence of the subchronic exposure to Al on the dissociated Ca(2+) in hippocampus neuron cells was observed.

RESULTSThe dissociated Ca(2+) in hippocampus neuron cells in the middle dosage group and the high dosage group [(412.25 +/- 53.20), (467.37 +/- 32.85) times] was lower than those in the control group [(293.91 +/- 32.21) times] respectively (P < 0.01), and correlated positively with the dose and dissociated Ca(2+) (r = 0.861, P < 0.01). Compared with the control group, the latent period was lengthened (P < 0.05) in the middle dosage and the high dosage group.

CONCLUSIONThe subchronic exposure to AlCl(3) in mice affects the dissociated Ca(2+) in hippocampus neuron cells. The increase of dissociated Ca(2+) in hippocampus neuron cells may be correlated with the disfunction of cognition in the aluminium intoxicated mice.

Objective To investigate the effects of hypoxia on the features and chemoresistance of cancer stem cells in Hep-2 cells and underlying mechanism. Methods The shRNA interference recombinant plasmid targeting HIF-1α was synthesized and transfected into Hep-2 cells. The HIF-1αknockdown Hep-2 cells were established after clonal selection and the expression of HIF-1α was measured.The cellular features including proliferation,clonal formation,cell cycle,apoptosis and CD133 phenotype were measured in Hep-2 cells cultured under hypoxic condition in vitro. CD133 + cells were sorted from Hep-2 cells with flow cytometry. Clonal formation test and cisplatin treatment were carried out,and theexpressions of related genes( Oct-4,suvivin and p53 ) in CD133 + cells were measured.Results HIF-1αknockdown Hep-2 cells was successfully established,as evidenced by the reduced mRNA and proteinexpressions of HIF-lα. The Hep-2 cells cultured under hypoxic microenvironment showed higher proliferation and clonal formation activity,cell cycle arrest in G0/G1,lower apoptosis,up-regulated CD133,however the effects of hypoxia reduced in HIF-1α knockdown Hep-2 cells.CD133 + cells were successfullysorted from Hep-2 cells,and the CD133+ cells showed increased clonal formation activity and cisplatintreatment resistance in hypoxia. Also the effects of hypoxia on CD133 + cells decreased with HIF-1αknockdown,showing down-regulated Oct-4 and survivin and up-regulated p53.Conclusions Hypoixa caninduce the features of cancer stem cells in Hep-2 cells and increase proliferation,differentiation and chemoresistant ability of CD133 + cells,which might be correlated with the changes in expressions of HIF-1 αand related genes regulated by HIF-1 α.

BACKGROUNDIn addition to the well-known antibodies against human leukocyte antigens (HLA)-induced kidney-graft rejection, polymorphic major-histocompatibility-complex (MHC) class I-related chain A (MICA) antigens can elicit antibodies and have been suggested to play a role in the antibody-mediated allograft rejection (AMR). We carried out a prospective study of MICA antibodies in post-renal transplant patients to determine the association between MICA antibodies, C4d staining, histological features, and graft outcome.

METHODSWe tested 52 patients who had biopsy results due to graft dysfunction. The MICA antibodies in concurrent sera were determined by Luminex. All patients were followed up for one year after renal biopsy. The influence of antibody production on the function of graft was analyzed.

RESULTSAntibodies against MICA were positive in 15 out of the 52 patients (28.9%). The presence of MICA antibodies was associated with renal-allograft deterioration. During one-year follow-up, the estimated glomerular filtration rate (eGFR) decreased (24.0 ± 3.4)% among recipients with anti-MICA antibodies. However, among recipients without anti-MICA antibodies, the eGFR has declined only (8.4 ± 3.0)% (P = 0.017). The association between C4d staining, histological features and MICA antibody production was found no significant difference.

CONCLUSIONBesides anti-HLA antibodies, the presence of post-transplant MICA antibody is associated with poor graft outcome and increases the risk of graft failure.
