自体颅骨碎片及屑修补颅骨缺损(附60例报告)

应用自体颅骨碎片及骨屑对60例在造成颅骨缺损术同时行颅骨缺损修补术。缺损面积直径最小者2cm,最大者10cm。术后随访1个月至5年,病人颅骨缺损修补处外观正常,无凹陷,触之硬,与正常颅骨处类似。6个月拍X线片示颅骨修补处类似正常颅骨形态。     

中性粒细胞的化学发光测定

用化学发光法检测粒细胞吞噬功能具有灵敏、准确、快速等优点。用我校同位素实验室LS3801型液体闪烁分析仪,全部使用国产试剂,建立了分离的中性粒细胞化学发光测定法,并对影响因素作了初步观察和探讨。实验表明,此法既可用于中性粒细胞吞噬杀菌功能机理研究,亦可用于临床监测。对糖尿病人粒细胞功能化学发光测定结果,显示了此法应用的潜力。     

Natural history of atopic dermatitis and its relationship to serum total immunoglobulin E in a population-based birth cohort study

We investigated the natural history of atopic dermatitis (AD) in a population-based birth cohort and assessed whether children at risk of visible eczema at 5 years of age can be identified from total immunoglobulin E (IgE) levels measured at 8, 12 and 18 months. AD data collected included a whole body examination for visible eczema at 49 months (4 years) and 61 months (5 years) of age and parent completed questionnaire data throughout their early lives. Children were divided into four groups based on their natural history of early AD: persistent (AD at 1, 6, 18, 30 and 42 months, n  = 34), intermittent early onset (before 18  months of age, n  = 495), intermittent late onset (18–42 months of age, n  = 273) and unaffected ( n  = 429). Visible eczema at 5 years of age was present in 12.2% (117/957) (95% confidence interval [CI] 10.1–14.3%) of the children. Levels of total IgE at 8, 12 and 18 months of age were associated with early onset of AD, but not with AD of later onset. For all four natural history groups, the geometric mean total IgE at 12 months was higher in those who subsequently had visible eczema than those who did not. However, the degree of overlap was such that total IgE at 12 months of age was a poor predictor of eczema at age five. A cutoff point of 78 kU/l had the highest positive predictive value for visible eczema at 5 years of age of 28.6%, with a sensitivity of 12% and specificity of 95%.     

第二足趾跖侧菱形皮瓣转移改形法再造拇指

目的介绍第二足趾跖侧菱形皮瓣转移改形再造拇指的方法。方法用传统方法切取第二足趾后,于第二足趾近段跖侧设计菱形皮瓣,用180°逆形转移或向远侧直接推进的方法将皮瓣嵌入第二足趾跖侧狭细处,以改善其外形。结果临床应用6例,再造拇指全部存活。术后随访3～24个月,再造拇指外形美观,感觉运动恢复满意。结论用第二足趾跖侧菱形皮瓣转移改形法再造拇指,能明显改善第二足趾的外形,使再造拇指更美观。     

卡巴胆碱对多器官功能障碍综合征小鼠脏器功能和结构的保护作用

目的:观察卡巴胆碱(carbachol,Car)对酵母多糖致多器官功能障碍综合征(MODS)小鼠多脏器功能和结构损伤的防护作用。方法:采用腹腔注射酵母多糖的方法复制小鼠MODS模型。雄性C57BL/6小鼠随机分为正常对照组(n=10),MODS 6、24、48 h组(n=30)和MODS Car 6、24、48 h防治组(n=30)。MODS组在致伤后腹腔注入生理盐水;MODS Car防治组在致伤前24 h内分3次灌胃注入卡巴胆碱。观察酵母多糖致伤后早期(48h内)动物死亡率,检测各组血丙氨酸转氨酶活性、尿素氮和肌酐水平,镜下观察致伤后48 h动物肝、肺、肾、心等脏器的组织病理学改变。结果:在酵母多糖致伤后48h内,MODS组小鼠死亡率达26.6%,MODS Car防治组的小鼠死亡率为10.0%。MODS组小鼠血浆ALT、BUN和Cr在伤后6h升高,而同时间点经卡巴胆碱预处理的小鼠血浆ALT、BUN和Cr仅略有升高,明显低于MODS组。光镜下观察发现,MODS组小鼠肝脏、肺脏、肾脏和心脏发生明显的病理改变,主要表现为脏器实质细胞浊肿、变性,间质充血、水肿和炎性细胞浸润,而卡巴胆碱防治组小鼠上述病变明显减轻。结论:预防性给予卡巴胆碱可以降低MODS急性期动物的死亡率,减轻脏器功能和结构的损伤,对急性炎症期的脏器损伤具有保护作用。     

Integrating children's services in England: national evaluation of children's trusts

Background Poor co‐ordination of services can have severe consequences for disadvantaged children with complex needs. Since 2003 national and local governments in England embarked on sweeping reforms aimed at improving and integrating local health, education and social services for children. These were to be organized locally by children's trusts and piloted by 35 children's trust pathfinders. Methods This study described and compared the experience of integrating children's services in all 35 children's trust pathfinders, covering 20% of children in England. It had a prospective mixed‐methods design. Over 3 years we interviewed 147 managers and professionals working in the children's trusts, including 172 semi‐structured interviews, carried out two questionnaire surveys of the 35 children's trusts and analysed official documents. Results In most areas different agencies jointly commissioned children's services, especially for mental health, disabilities and multi‐purpose children's centres, and increasingly pooled finances. Provision of multi‐agency and multi‐professional services was increasing. Professionals generally supported these changes but found them stressful. All children's trusts appointed directors of children's services and established boards representing multiple agencies. Systems for sharing information about individual children were mostly in place but were still underused. Health services were generally less involved in joint work than were local authorities' education and social care services, with notable exceptions. Areas where local authorities and health authorities shared geographical boundaries made most progress. Some children's trusts made few changes beyond their statutory obligations. Conclusion Children's trusts enabled major changes to services in areas where local actors and organizations were motivated and empowered. In other areas the remit of children's trusts was often too broad and vague to overcome entrenched organizational and professional divisions and interests. Policymakers need to balance facilitation of change in areas with dynamic change agents with methods for ensuring that dormant areas and agencies are not left behind.
