Abstract

Introduction: The aim of this study was to investigate how peritoneal dialysis and other influencing factors affect patients' cognitive function. Methods: The 85 subjects in the study group were regular patients in our center. The control group included 88 age and gender matched healthy individuals who were with normal renal function. The study subjects' cognitive levels and related factors were analyzed using several screening instruments: the cognitive function was measured using the Montreal Cognitive Assessment Scale and statistical analysis was conducted based on the relevant data. Results: The results showed that cognitive impairment was higher in peritoneal dialysis patients than in non‐dialysis subjects. Age and educational background were single factors that affected cognitive function, which was more likely to be impaired at a higher age level and/or a lower educational level. Conclusion: Cognitive function can be impaired by peritoneal dialysis, and age and education levels are influencing factors. [ABSTRACT FROM AUTHOR]

Abstract

Ferroelectric devices are widely applied in many fields, such as energy conversion and communication. The aging effect in ferroelectric materials plays a central role in the reliability of the related equipments. But it is very difficult to understand the origin of aging effect in ferroelectrics because these materials possess different defects and exhibit various aging behavior. The reverse transition temperature in lead titanate doped with lanthanum increases during aging at ferroelectric phase was reported. It is well known that lattice defects, such as vacancies and solute atoms, are ubiquitous in crystalline solids. These point defects affect physical properties in ferroelectrics significantly. The abnormal increase of the reverse transition temperature was discussed in terms of diffusion of point defects during aging. Dielectric performance in the material after aging was measured and discussed as well.

Abstract

To investigate the effects of normal human bone marrow fibroblastoid stromal cell lines HFCL on the proliferation of multiple myeloma cell lines RPMI8226, the co-culture system of RPMI8226 with HFCL was established, the adhesion ratio was determined by MTT colorimetric assay, growth curves were determined by trypan blue exclusion, the mitotic index (MI) of RPMI8226 cell was observed by Wright-Giemsa staining. Flow cytometry and Western blot were used to study the changes of cell cycle and expression of proliferating cell nuclear antigen (PCNA), respectively. The results showed that in co-culture the adhesion ratio of RPMI8226 after 1 hour was 29.4%; the proliferation of RPMI8226 cell line in direct contact with HFCL cell line was inhibited as compared with RPMI8226 in suspension. No obvious changes were observed in RPMI8226 cell separated by transwell inserts. The percentage of G(1) phase cells of RPMI8226 cell line in direct contact with HFCL was higher than that of RPMI8226 in suspension, and the percentage of S phase cells was lower. Moreover, the MI of RPMI8226 cell line in suspension was higher than that of RPMI8226 cell line in direct contact with HFCL cell. The expression of PCNA in RPMI8226 cell line in suspension was higher than that of RPMI8226 cell in direct contact with HFCL cell. It is concluded that the normal human bone marrow fibroblastoid stromal cell HFCL inhibits the proliferation and progression of cell cycle of multiple myeloma cell line, RPMI8226.
