广东省儿童乙型肝炎疫苗纳入计划免疫管理10年后血清学效果分析

为研究广东省乙型肝炎 (乙肝 )疫苗纳入计划免疫管理 10年后儿童血清乙肝病毒感染标志物 (HBVM )的变化 ,采用分层多阶段随机抽样法 ,将全省分 4层 ,共抽取 12个县 2 4个村的 196 3名儿童为研究样本。采血用固相放射免疫法 (SPRIA)检测乙肝病毒表面抗原 (HBsAg)、乙肝病毒核心抗体 (抗 HBc)、乙肝病毒表面抗体 (抗 HBs)。2 0 0 2年调查 1～ 14岁儿童乙肝疫苗接种率为 78 81% ,全程接种率为 74 17%。其中 1～ 9岁儿童乙肝疫苗全程接种率为 81 73% ,10～ 14岁为 6 0 32 %。 1～ 14岁儿童HBsAg携带率、抗 HBc阳性率、HBV感染率分别从 1992年的 19 86 %、5 3 5 9%、71 4 1%降至 2 0 0 2年的 8 5 6 %、2 2 5 7%、31 33%。其中 1～ 9岁儿童的HBsAg携带率、抗 HBc阳性率、HBV感染率分别从 1992年的 17 88%、4 7 0 9%、6 7 4 4 %下降至 2 0 0 2年的 5 75 %、14 4 9%、2 1 81%。乙肝疫苗接种后 ,1～ 3岁儿童抗 HBs阳性率为 5 2 0 2 %～ 6 2 18%。由于实施了加强免疫 ,4～ 14岁儿童的抗 HBs维持在 5 9 32 %～ 6 5 80 %。广东省乙肝疫苗纳入计划免疫管理 10年后 ,全省 1～ 14岁儿童HBV感染率已大幅度下降 ,抗 HBs阳性率大幅度升高 ,取得了良好的经济和社会效益。     

羊水细胞培养宫内诊断的应用(附120例分析)

报告120例羊膜腔穿刺羊水细胞培养结果:在成功的99例中,发现二例染色体异常,核型为47,xy,+18和46,xx/47,xx,+F,在21例失败中出现一例眼球畸形。培养成功率为82.5%;染色体异常检出率为2.02%。无一例因羊膜腔穿刺而导致流产,但出现一例轻度羊水栓塞合并症。并对羊水细胞培养在产前宫内诊断中应用价值及术后并发症进行了讨论。     

Oral midazolam premedication for paediatric day case patients

Forty-nine children having day-stay surgical procedures were randomly assigned to receive oral midazolam 0.75 mg·kg^?1 or placebo in a double blind fashion. The child's level of anxiety was assessed before premedication using parental, child and observer scales. The child and observer anxiety scores were repeated in the anaesthetic room. Most children presented for anaesthesia in a calm state, irrespective of whether they had received midazolam. Parents tended to overestimate their child's level of anxiety. Observer anxiety scores reliably predicted behaviour during induction of anaesthesia in the absence of a sedative. Observer scores decreased in the midazolam group (P<0.02), but not in the placebo group, children below six years having the greatest decrease with midazolam. The median time to discharge from hospital was delayed by 30 min in the midazolam group (P<0.01). Children do not require routine sedative premedication for day case procedures, but oral midazolam is useful in producing calm behaviour in those children with high observer anxiety scores.     

产后并发症341例分析

报告本院1981年1月至1985年12月,住院分娩4588例中产后并发症341例,发病率为7.43％。其中,产后出血1189例,占4.12％;分娩损伤71例,占1.55％;其它产后病81例,占1.76％。妊娠41—42周并发症发生率为11.14％;超过42周高达15.56％。分娩方式以剖腹产术后并发症最多,占12.48％,提示应对手术中无菌操作与环境,以及分娩后处理应予以足够重视。     

医院统计在医院要素分配中的作用

目的 为支持医院内部要素分配调整改革，医院统计应展开与要素分配有关的项目进行统计，为医院要素分配向高、精、尖、绩效好的医务人员倾斜提供统计数据。方法 应用ExCEL软件的合并功能对病人信息和病案信息进行深层次的挖掘、提取、重新整合统计，制成简明易懂的统计报表给予反馈公布，作为医师提取个人奖酬、职称晋升或聘任竞岗的考核依据。结果通过统计作用实现了劳动价值创造，调动了广大医务人员的积极性，促使医院经营理念成为引导个人自觉行为的杠杆，实现了医院提高综合竞争实力的整体效应。结论 要素分配中统计工作应遵循公平、合理、反映医院经营理念的原则和利用网络科技实现高效管理并且应与改革同步，深化统计内涵，完善医院的统计方法。     

Labman and Linkman: A data management system specifically designed for genome searches of complex diseases

Two programs have been developed to manage linkage analysis data. The first program, LABMAN, is a comprehensive laboratory data management system organizing pedigrees, blood DNA samples, DNA markers, Southern blot or polyacrylamide gels, autoradiographs, and marker-allele typings generated from these samples. Output includes mendelization checks for genetic incompatibilities in typings and formatted files ready for linkage analysis. LABMAN can also compress highly polymorphic allele systems into smaller allele systems facilitating analysis of large systems. The second program, LINKMAN, provides data management for lod score output from linkage analyses. It reads linkage analysis output files, calculates lod scores by family, associates lod scores with specific marker and family identifiers, and stores these data in a database where they can be combined with lod scores from previous analyses. LINKMAN easily incorporates any of a wide variety of genetic models. It produces formatted output of lod scores by user-specified criteria for reports or as ASCII files for input to other programs. If desired, tests of homogeneity of linkage across families can be run via the HOMOG program [Ott, 1991] and their output included in reports. The programs include features critical for conducting genome searches of complex diseases: They are easy-to-use, well-tested, and reliable. Data from multi-center investigations can be easily combined for analysis. Moreover, they include extensive error-checking capabilities, and they are specifically set up to protect blindness between laboratory workers and data analysts. LABMAN and LINKMAN are currently available free of charge under DOS. © 1994 Wiley-Liss, Inc.

‘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.
