‘You have to learn to live with it’: a qualitative and quantitative study of older people with asthma

Introduction: Asthma mortality has declined overall because of a range of public health initiatives. In western countries, the majority of asthma deaths now occur in people over the age of 50. The reasons for the poorer response of older age groups to public health asthma initiatives are not known. Objectives: We undertook a study to investigate the disease perspectives of older people with asthma and barriers which may exist and prevent optimal asthma care. Methods: Fifty‐five participants (16 male and 39 female) aged over 50 from an inner city, suburban area and a rural region were recruited. Lung function was measured, and questionnaire data on asthma symptoms, knowledge and control, medication use and respiratory health were collected. Participants were also interviewed in‐depth, and the quantitative and qualitative data were triangulated. Results: Participants with a duration of asthma for >30 years reported significantly fewer symptoms and better quality of life irrespective of asthma severity, indicating less appreciation of symptoms in those with a long asthma duration. Interviews revealed this was related to previous asthma management strategies when treatment options were limited. Participants with a recent diagnosis sought understanding of asthma and the reason for their illness. Initiatives to improve asthma care in older people need to reflect these findings. Conclusions: Self‐management strategies for older people need to be tailored according to the time of disease onset and the duration of disease.

VEGF基因体外转染大鼠骨髓间充质干细胞的实验研究

目的:探讨脂质体介导血管内皮细胞生长因子(VEGF)基因转染大鼠骨髓间充质干细胞(MSCS)应用于基因治疗的可行性、安全性。方法:体外分离、培养、鉴定MSCs,PcDNA3.1(-)/VEGF165质粒转染MSCs,转染后用免疫荧光和ELISA检测MSCs表达VEGF蛋白的情况,MTT检测MSCs对VEGF质粒转染的敏感性。结果:骨髓中分离得到MSCs,流式细胞检测显示MSCs不表达CD34和CD45,但表达CD90。透射电镜观察可见细胞浆中含大量粗面内质网和分泌颗粒。VEGF基因转染MSCs后第5天抗VEGF免疫荧光染色约90%的MSCs呈阳性,ELISA检测结果显示PcDNA3.1(-)/VEGF165质粒转染组细胞培养上清液中VEGF含量明显高于对照组,并于转染后第5天达到峰值。MTT检测结果显示VEGF质粒转染对MSCs增殖无影响。结论:MSC可作为VEGF基因转染的靶细胞用于基因治疗。     

两种靶控方法输注异丙酚和瑞芬太尼的安全性和有效性比较

目的 比较靶控血浆浓度和效应室浓度输注异丙酚和瑞芬太尼的安全性及有效性。方法 选择44例腹腔镜胆囊切除的病人,年龄18～65岁,ASA Ⅰ～Ⅱ级,随机分为靶控血浆浓度组(P组)和效应室浓度组(E组)。设定异丙酚和瑞芬太尼的靶浓度分别为4 μg/ml和2 ng/ml。观察给药后意识消失时间、血液动力学变化以及听觉诱发电位指数(AAIs)的变化。术中调整两药靶浓度保持AAIS低于20。记录术毕停药后自主呼吸恢复和睁眼时间和AAIs的恢复。结果 E组意识消失的时间[(0.45±0.10)min]明显短于P组;此时两药的用量也明显高于P组。两组均能引起明显的低血压,但降低程度相似,且均未见严重的心血管副作用。AAIs在意识消失时P组为41±22;E组49±16:但插管时均在20以下。术中血液动力学保持较低水平(P<0.01)。两组的插管评分、麻醉质量评分相似。术后自主呼吸恢复时间和睁眼时间两组均无统计学差异。Aldrate评分及手术结束时疼痛评分差异均无显著性。结论靶控血浆和效应室浓度输注均可达到满意的麻醉效果,但靶控效应室诱导时间更短,且无明显心血管副作用。     

少年儿童颞下颌关节紊乱综合征的错雅(牙合)特征

①目的 探讨少年儿童颢下颌关节紊乱综合征(TMJD)的错拾特征。②方法 用一般口腔检查工具对青岛地区的550例TMJD病人进行拾检查。③结果 80．0％的病人有不同程度的错He，其中个别牙齿错位所占的百分率最高(42．4％)，其次为高度不调、长度不调和宽度不调；不同牙龄期病人错He特征不同。④结论 本研究结果可以作为TMJD早期正畸治疗以及治疗时对错He分析和诊断的参考。     

从中日沿海城市部分老年人生活满足感比较看老年社区护理的发展

目的 通过比较中日两围老年人生活满足感，探讨老年人社区护理的发展方向。方法 中国大连市选取60岁以上老年人，进行人户调查，日本滨松市选取俱乐部的65岁以上老年人，填写问卷。结果 除在与亲人、朋友交往及存钱以防万一等方面外，2国老年人在其他生活满足感方面比较，差异均有统计学意义，P〈0．05。结论 中日两国不同的经济基础导致了不同层次需求的差异。在中国发展老年人社区护理，一方面可以借鉴国外经验，从物质基础上改进和完善；另一方面，借助传统文化优势，从社会风气上进行促进。     

腺病毒载体介导CTLA4Ig基因治疗小鼠变应性鼻炎

目的 检测CTLA4Ig-重组腺病毒载体（Ad-CTLA4Ig）在变应性鼻炎治疗中的作用。方法 采用卵清蛋白（OVA）致敏和激发诱导小鼠变应性鼻炎。实验组在OVA激发前30min予以Ad-CTA4Ig腹腔注射。未转CTLA4IgcDNA的腺病毒载体（Adv）作对照。比较各组动物鼻部症状和鼻粘膜形态学改变，并采用ELISA法测定血清中OVA－特异性IgE水平。结果 CTLA4Ig重组腺病毒实验组小鼠鼻部症状和鼻粘膜病理改变不明显，并且血清中OVA－特异性IgE水平明显低于对照组（P＜0.05）。结论 Ad-CTLA4Ig可防治小鼠应变性鼻炎的发生，提示CTLA4Ig-重组腺病毒载体有可能运用于临床变应性鼻炎的治疗。     

Gliomatosis peritonei

Gliomatosis peritonei, the miliary implants of mature glial tissues on the peritoneum or omentum, is a rare complication of solid ovarian teratoma. Our case is reported and 38 previously reported cases are reviewed. The grade of the primary tumors varied from grade 0 to grade 3. Only five cases were composed entirely of mature tissues. Five of the 39 patients died. Despite of varied therapy, the rest of the patients were alive from 3 months to 38 years later. Inspite of intraperitoneal implants, the prognosis in patients with these tumors is good, irrespective of the mode of therapy. On the basis of this study, we recommended a conservative therapy for the primary tumor and therapy for the implants is not required.
