HBV血清学标记携带者的传染受许多因素的影响。本研究采用多因素分析方法,定量描述了各种类型HBV血清学标记携带者家庭内传染性及有关因素影响的大小。家中上次HBsAg携带与易感者HBsAg和HBeAg阳转呈正相关。家中上次抗-HBc携带与易感者抗-HBc阳转呈正相关,OR=5.98;但与抗-HBc滴度变化无显著联系。而家中上次抗-HBc携带,HBsAg与抗-HBc同时携带与易感者HBsAg和HBeAg阳转呈负相关。年龄与HBsAg阳转呈负相关;文化水平与易感者抗-HBs阳转亦呈负相关;手术史、注射史与乙肝续发感染正相关。多因素分析对阐明人群中大量HBV血清学标记携带者的动态变化有一定意义。 相似文献

Psychological Disturbance and its Associations in the Children of the Gujarati Community 总被引:1,自引:1,他引:0
Latha Hackett Richard Hackett David C. Taylor 《Journal of child psychology and psychiatry, and allied disciplines》1991,32(5):851-856
The infrequent referral of Asian children to child psychiatry clinics was noted. By administering Rutter's scale A2 to samples of Gujarati and English parents with children between the ages of 4 and 7 years a lower rate of disturbance was demonstrated among the Asian sample providing an explanation for the original observation. Family and child-rearing factors associated with disturbance were identified. 相似文献

BACKGROUND: The isolated perfused canine kidney has been established as a valid model for conducting both renal physiology and transplantation research. This model is of particular importance for developing new strategies to improve graft function after renal transplantation. In the present study, a newly developed method using isolated haemoperfused porcine kidneys was adapted for use in canine kidneys. In contrast to haemoperfusion, synthetic perfusion media can be standardized and can prevent the initiation of blood-mediated reperfusion reactions. Thus, an additional aim was to determine whether blood could be replaced by synthetic cell-free perfusion solutions. METHODS: Canine kidneys (n = 30) were harvested from donors euthanized in veterinary practices for causes unrelated to the present study. The kidneys were isolated and perfused with autologous blood or cell-free synthetic electrolyte buffer (Tyrode solution). During perfusion, we monitored renal perfusate flow (RPF), glomerular filtration rate (GFR), electrolyte and glucose reabsorption, oxygen consumption and urine concentration. RESULTS: Changes in perfusion medium did not affect the RPF. In contrast, GFR, urine concentration and oxygen consumption were significantly higher, whereas fractional excretion of sodium and glucose were significantly lower in blood- than in Tyrode-perfused kidneys. CONCLUSIONS: This system offers a simple model for studying whole-organ functional alterations after acute renal ischaemia. Renal function indicators were below values reported during in vivo physiological conditions. These functions were better conserved when kidneys were perfused with autologous blood than with Tyrode. 相似文献

Acquired immunodeficiency syndrome (AIDS) is a serious disease that has special concern for the health care provider. AIDS has continued to grow despite control efforts. As the disease infectivity period remains lengthy, and the heterosexual population is affected to a greater degree, the level of anxiety has also risen despite educational endeavours. Many fears and anxieties have been associated with AIDS patients by health care workers. The reduction of stress, perceived risk and discomfort following educational efforts have been supported in past research. Educational programmes will need to be given for current health care workers at all levels as well as nursing students. Future nurses must be prepared to meet this challenge. This study was conducted using a convenience sample of nursing students at a university in western United States. Its purpose was to assess any changes that occurred in state anxiety following an educational presentation. Spielberge's State-Trait Anxiety Inventory was used as the measurement instrument. Some anxiety levels were significantly reduced. 相似文献

目的研究心理训练对高特质焦虑新兵考核时生理指标和成绩的影响。方法采用个人评价问卷(PEI)、状态.特质焦虑问卷(STAI)和简易应对方式问卷对参加考核的新兵实施团体测试。将被试者分为对照组、低特质焦虑组、高特质焦虑组和干预组,对干预组进行自我评价、潜能开发、团队精神强化、应对方式的心理训练。测试考核前后生理指标差值及考核成绩的变化。结果干预组新兵军事考核前后收缩压、舒张压和脉搏三项生理差值与考核成绩明显优于高特质焦虑组(P〈0.05)。结论系统的心理训练可有效改善新兵对应激情景的生理和心理反应,提高作业绩效。 相似文献

The influence of behavioral state on the induction of long-term enhancement (LTE) of hippocampal synapses was studied in chronically prepared animals. Perforant path evoked field potentials and EEG were recorded from fascia dentata during slow-wave sleep (SWS) and waking. LTE was strongly suppressed during SWS, suggesting that hippocampal information storage may be inactivated at certain phases of the sleep cycle. Normal LTE was observed in the same animals while awake. 相似文献
