胆囊炎和胆石症的饮食疗法

胆囊炎、胆石症的发病及复发与饮食密切相关。中医素有“药食同源”之说,《内经》曾有“虚则补之,药以祛之,食以随之”和“谷肉果菜,食养尽之等饮食疗法的论述。饮食疗法简称食疗,首先应遵循食疗原则,主要是注重辨证施食,并辅以药膳。食疗原则胆囊炎、胆石症的食疗目的是注意饮食习惯避免诱发疼痛发作(即胆绞痛),并保证胆囊收缩正常,使胆汁排泄通畅,去除引起胆汁淤滞的因素,抑制胆石的生成。其食疗的基本原则是:1饮食规律忌暴饮暴食。2控制脂肪摄入,适量摄取蛋白质3材料要新鲜,烹调要柔软,口味要清淡。4少吃辛辣品,禁饮酒。5多吃蔬菜、水果,…     

Validation of impedance cardiography measurements of cardiac output during limited exercise in heart transplant recipients

Abstract. Twenty-one patients were studied at rest and during exercise after heart transplantation to compare cardiac output measured by thermodilution and impedance cardiography. Exercise was performed on a bicycle ergometer over a limited range of work load (25 and 50 watt) whilst metabolic gas exchange was recorded. One patient was studied at rest whilst his circulation was maintained by a Jarvik-7 artificial heart. The values of cardiac output measured by impedance cardiography corresponded closely with the flow rate from the artificial heart. There was also close agreement between the impedance and thermodilution measurements of cardiac output at rest and during exercise. Both measurements followed the changes in heart rate and oxygen consumption. Both thermodilution and impedance cardiography methods elicited good reproducibility of cardiac output measurements at rest and during exercise. These observations suggest that the noninvasive and continuous record of cardiac output obtained by impedance cardiography can be used for the postoperative monitoring of heart transplant recipients.

山区教师心理健康状况调查

教师的心理健康直接关系着教师自身的职业成长和学生的发展，对于素质教育质量的提高具有重要意义。在我国，教育发展存在显著的地区差异。相对于城市而言，广大农村和山区教育落后，直接制约着经济社会的进一步发展。山区教育落后的重要原因之一在于教师素质相对落后，其中教师的心理健康问题迫切需要得到关注。     

额叶内侧面损伤的临床特点及救治

目的 总结17例额叶内侧面损伤的临床特点及救治经验。方法 对我科1999年7月至2003年4月收治的额叶内侧面损伤患者进行回顾性分析。结果 手术治疗1例，恢复良好，保守治疗16例，其中恢复良好12例，中残2例，死亡2例，全组死亡率11．77％。结论 额叶内侧面损伤一般意识障碍较轻，但易直接发生枕骨大孔疝，严密观察病情及动态CT检查，颅内压监测，不拘泥传统手术指征，及时抓住手术时机，可有效降低致残率及死亡率。

Patterns of eye care use and expenditures among children with diagnosed eye conditions.

PURPOSE: Little is known about use and expenditure patterns of children's eye-care services and about possible disparities in care among children. This report describes the use and expenditure patterns of eye care and non-eye care services for children under 18 years old in the United States. METHODS: Levels of use and expenditure were estimated using self-reported information from the nationally representative Medical Expenditure Panel Surveys (1996-2001) for 48,304 subjects under 18 years old from randomly selected households in the United States. Means presented for children with and without diagnosed eye conditions were adjusted for child and family characteristics using generalized linear models. RESULTS: Children with diagnosed eye conditions had higher levels of use and expenditure than children without diagnosed conditions. Families of children with diagnosed eye conditions incurred higher out-of-pocket expenditures. Black children and children living below 400% of the federal poverty level had lower levels of use and expenditure, indicating that they received fewer and less intensive services. CONCLUSIONS: Children with diagnosed eye conditions experienced higher overall use of health care. Some groups of children appear to be underserved. Estimates of use and expenditure patterns, stratified by socioeconomic factors, will be needed to plan for future delivery of children's eye and vision care services and to assess progress toward Healthy People 2010 goals.     

腹腔镜下输卵管妊娠保守性手术38例分析

目的探讨腹腔镜下输卵管妊娠保守性手术不同术式的近期效果。方法对输卵管妊娠腹腔镜下行保守性手术38例患者的临床资料进行回顾性分析。结果所有手术均在腔镜下顺利完成,发生持续性妊娠率2%(1/38)。结论输卵管妊娠是腹腔镜手术的最佳适应证,镜下开窗术是标准的保守性手术,对年轻有生育要求者更具临床价值,而伞端挤压术发生持续妊娠的倾向性大,应尽量避免。     

脑电双频指数指导老年病人异丙酚麻醉诱导用量

[目的]通过监测老年病人麻醉诱导时脑电双频指数(BIS)的变化,探讨既能维持足够麻醉深度又能避免严重低血压的异丙酚诱导用量。[方法]40例ASA II～I级的老年病人(65～85岁),随机分成两组。A组静脉注射异丙酚1.6 mg/kg;B组静脉注射异丙酚,其用量是使BIS下降到40～50时的用量。两组均复合维库溴铵0.1 mg/kg和瑞芬太尼1ug/kg诱导后行气管插管分别记录基础值、插管前、插管后1 min、5 min和10 min时的收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP)、心率(HR),同时记录诱导异丙酚用药量和BIS的变化。[结果]A组异丙酚诱导用药量(99.7±18.05)mg,平均(1.64±0.7)mg/kg,B组(82.9±12.5)mg,平均(1.35±0.5)mg/kg,差异有统计学意义(P﹤0.05)。A组血压(BP)和BIS比B组明显降低。[结论]老年病人异丙酚麻醉诱导的合适用量为(1.35±0.5)mg/kg;既能维持老年人足够的麻醉深度又能避免严重低血压的发生。     

出国务工妇女细菌性阴道病调查结果分析
