前列腺切除术围术期出血与临床护理预处理的关系

研究护理中术前服用度他雄胺2周减少前列腺内二氢睾酮和前列腺组织血管分布对前列腺术后出血的影响。本研究纳入了83例符合TURP适应症的良性前列腺增生患者。度他雄胺组由40名患者组成,术前两周内接受度他雄胺(0.5 mg/d)治疗;对照组由43名患者组成,术前两周内不接受度他雄胺治疗。根据术前、术后、术后24 h的血清血红蛋白(Hb)和血细胞比容(Hct)水平来评估失血情况。本次研究还探究了药物对留置尿道导管的使用时间、连续盐水膀胱冲洗时间和住院时间的影响。术后和术后1 d平均失血量方面,度他雄胺组低于对照组(ΔHb=(0.65±1.27) g/d L∶(1.16±0.73) g/d L,(1.30±1.00) g/dL∶(1.86±1.05) g/dL,p=0.019,p=0.011;ΔHct=(1.89±3.83)%∶(3.47±2.09)%,(3.69±2.95)%∶(5.39±3.23)%,p=0.016,p=0.011)。此外,在度他雄胺组中,尿道留置导尿管天数((2.95±1.02) d∶(3.92±1.14) d,p=0.000)、连续盐水膀胱冲洗时间((1.81±1.08) d∶(2.36±1.06) d,p=0.016)和TURP后的住院时间((3.95±1.09) d∶(4.76±1.19) d,p=0.001)较小。本研究表明,在TURP术前护理中用度他雄胺进行两周的治疗,可减少术后出血和TURP术后住院时间。这种临床护理预处理可用于减少与TURP相关的手术出血,建议临床使用。     

Cross-generational impact of a male murine pheromone 2-sec-butyl-4,5-dihydrothiazole in female mice

The current understanding of the activity of mammalian pheromones is that endocrine and behavioural effects are limited to the exposed individuals. Here, we demonstrate that the nasal exposure of female mice to a male murine pheromone stimulates expansion of mammary glands, leading to prolonged nursing of pups. Subsequent behavioural testing of the pups from pheromone-exposed dams exhibited enhanced learning. Sialic acid components in the milk are known to be involved in brain development. We hypothesized that the offspring might have received more of this key nutrient that promotes brain development. The mRNA for polysialyltransferase, which produces polysialylated neural cell adhesion molecules related to brain development, was increased in the brain of offspring of pheromone-exposed dams at post-natal day 10, while it was not different at embryonic stages, indicating possible differential brain development during early post-natal life.     

80例急性心肌梗死患者心电监护及护理

目的总结急性心肌梗死患者心电监护及护理经验。方法对本院性心肌梗死患者及时进行心电监护,对出现的心律失常者进行对症处理。结果本组80例患者中出现心律失常55例,其中室性心律失常48例,临床治愈45例;出现心室颤动7例,4例及时电复律转为窦性心律,3例抢救无效死亡。本组心律失常均发生在心肌梗死后1周内,尤其是发病24小时内,出现最多。结论心律失常是心肌梗死患者常见的并发症,也是患者死亡的主要原因,持续心电监护对患者心律失常的及时发现、明确诊断、指导抢救有重要意义。     

Maternal nurturing is dependent on her innate anxiety: the behavioral roles of brain oxytocin and vasopressin

The maternal brain undergoes remarkable physiological and behavioral changes in the peripartum period to meet the demands of the offspring. Here, the brain neuropeptides oxytocin and vasopressin, together with prolactin, play important roles. These neuropeptides are critically involved in the regulation of maternal behavior. Furthermore, reduced anxiety in lactation is another adaptation of the maternal brain. Therefore, a link between maternal behavior and maternal anxiety has been repeatedly postulated. This is supported by our studies in rats bred for high (HAB) and low (LAB) anxiety-related behavior. While female HAB rats become less anxious in lactation, their anxiety level is still four times higher compared with LAB dams. Interestingly, HAB dams display an intense and protective mothering style including increased arched back nursing and pup retrieval whereas LAB dams display only low levels of maternal care. The amount of maternal care directed towards the pups correlates with the mother's innate anxiety. In addition to differences in maternal care, HAB dams are also more protective as they show heightened aggression against a virgin intruder compared with the less aggressive LAB dams. The level of maternal aggression correlates with both their innate anxiety level as well as with the release of oxytocin and vasopressin in hypothalamic and limbic brain areas. Importantly, manipulations of the brain oxytocin and vasopressin systems alter maternal behavior and — depending on the brain region — can also alter the dam's anxiety. Thus, the mother's innate anxiety determines her maternal performance and oxytocin and vasopressin are involved in both parameters.     

心内科住院患者人性化护理问题的分析与对策研究

目的：探讨心内科实施人性化护理的问题及产生问题的原因,寻找有效的解决措施。这对提高护理质量,有效保证住院患者的安全,促进住院患者身心健康有重要意义,同时,也为临床护理提供依据。方法：对我院2011年1月-2011年3月心内科住院患者进行护理满意度和护理需求问卷调查。结果：调查数据显示,实施人性化护理患者的满意度为89．86％,较2010年有较大的提高。导致患者不满意的原因依次为护患沟通不足、护理人员专业素质差、护理人员缺乏经验和个别护理人员职业道德低下。根据患者需求调查数据显示,患者在病房环境、个人隐私尊重与保护、服务态度、医疗技术操作水平及职业道德5个方面还有较大需求。结论：人性化护理对改善医患关系,提高护理安全,促进患者的身心健康有积极的作用。依据调查的患者需求量,人性化护理还需要有针对性的改进和提高。

重症急性胰腺炎上腹联合侧腹壁切口术后的综合护理探讨

目的：观察上腹联合侧腹壁切口治疗重症急性胰腺炎（severe acute pancreatitis,SAP）术后综合护理的疗效。方法：对我院2006年1月至2010年6月在我科接受上腹和侧腹联合切口手术的46例SAP患者进行回顾性分析。其中26例患者接受综合护理,包括采用造瘘袋辅助护理、使用可调节式伤口保护罩、早期持续冲洗及负压吸引等;20例患者接受常规护理。比较两种护理策略对SAP开放性伤口的预后影响。结果：接受综合护理的患者再次手术率（5/26 vs 10/20,P=0.027）,住院周期（26.08±8.48 vs.31.95±8.82,P=0.03）及护士工作满意度（93.15±4.05 vs.87.45±5.90,P〈0.01）等方面均优于接受常规护理的患者。综合护理组患者住院期间死亡率（0/26 vs 3/20,P=0.075）及术后肠瘘发生率（1/26 vs 4/20,P=0.08）有降低的趋势。结论：采用综合护理可降低再次手术率,促进伤口愈合,缩短住院周期,可能降低肠瘘发生率及死亡率,提高护理疗效。     

Neonatal Milestones,Behavior and Growth Rate of Sumatran Rhinoceros (Dicerorhinus sumatrensis) Calves Born and Bred in Captivity

The birth of Sumatran rhino calves at the Cincinnati Zoo and Botanical Garden offered a unique opportunity to study early development and cow–calf behavior in this elusive, critically endangered species. Study goals were to: (1) record developmental milestones of newborn calves; (2) characterize cow and calf behavior during the first year following birth; (3) compare trends in the behavioral development of a male vs. female calf; and (4) record weight gain and footprint size throughout the first year. In addition to recording eight neonatal milestones, more than 450 hr of behavioral data were collected on each of the two calves (one male and one female) and their dam during the first 12 months of life. Neonatal milestones were achieved within 24 hr of birth with the exception of first defecation, which occurred at 16–18 days. Although nursing bouts decreased slightly in the second half of the year (from once every 90 min to once every 2 hr), they continued to occur frequently throughout the day and night. Therefore, calves grew rapidly from approximately 33 kg at birth to 400 kg at 12 months. Average daily weight gain for the first week was approximately 2.0 kg, whereas average daily weight gain for the remaining 12 months was slight (<1 kg) and did not differ between calves. Eating and resting occupied 70–80% of the Sumatran rhino cow and calves' time and no gender biases in either maternal investment or developmental parameters were noted. Finally, footprint measurements proved valuable for estimating calf age. Zoo Biol 31:546‐560, 2012. © 2011 Wiley Periodicals, Inc.
