If the seven constants were changed,the result of specimen testing would be affected directly.When we understand the meaning of the seven constants.the job of medical equipment maintenance and care will become more effective.Meanwhile,we should pay attention to the influence on the result caused by other factors of a constant besides the seven Coulter Constants.

The cascade release of cytokine the critical aggravation factor for acute pancreatitis,induces the multi-ple organ dysfunction syndrome (MODS) and death at last. Nuclear factor-kappa B as a number of regulation of the nuclear factor can specific bind with a variety of gene promoter sites κB site, which cause inflammatory reaction, apoptosis, pathophysiologic reaction. The specific inhibitor of nuclear factor-kappa B can inhibit the activity of nu-clear factor-kappaB, inhibit the body's inflammatory response, and improve the prognosis of acute pancreatitis; it may be a potential target site for acute pancreatitis therapy. However, the other researches also found that inhibition of nuclear facter-κB could significantly increase the aggravation of acute pancreatitis. Accordingly, nuclear factor-kappa B research possess the important rank about the body's inflammatory respanse.

ObjectiveTo investigate the level of caregiver burden of primary caregivers of children with autism,and explore the factors related to caregiver burden.Methods 177 caregivers of children with autism were tested with caregiver burden inventory(CBI) and childhood autism rating scale(CARS).A cross-sectional and multisite study design was used.ResultsThe scores of caregiver burden was ( 57.50 ± 14.91 ),and time-dependence burden and developmental burden were the most serious domains.Caregiver burden was affected by caregiver's age,caregiver's religious beliefs,caregiver's marital status,caregiver employment status and education degree and children's scores of CARS and degree of CARS( -0.151 ≤ r ≤0.282,P＜ 0.05 ).ConclusionThe data suggest that community care workers should pay attention to caregivers of children with autism and give them personalized health education and intervention according to the demographic characteristics of the caregivers and the severity of children disease.

BACKGROUND:Recently, there is more and more attention on uric acid (UA), especially the correlation with cardiovascular disease in the filed of epidemiology; however, researches of the effect of UA on endothelial cells are lack based on cytology.OBJECTIVE:To explore the effects of UA in different concentrations on human umbilical vein endothelial cells line (ECV304), malondialdehyde (MDA), nitric oxide (NO) and 3-(4,5-dimethyl thiazole-2)-2, 5-diphenyl thiazolyl blue (MTT)in vitro.DESIGN: Randomized controlled study based on ECV304.5ETTING: Department of Endocrine, Xijing Hospital, the Fourth Military Medical University of Chinese PLA.MATERIALS:ECV304 was provided by Department of Immunology, the Fourth Military Medical University of Chinese PLA; DMEM Iow-glucose medium by Gibco Company, USA; bovine serum by Beijing Yuanheng Shengma Biotechnology Researching Institute; trypsin by Gibco Company, USA; MTT by Huamei Company; dimethyl sulfoxide (DMSO) analytical pure by Tianjin Bodi Chemical Engineering Co.
