小儿急性肺损伤的短期肺功能随访

Objective To study the pulmonary functions of pediatric ALI/ARDS(acute lung injury/acute respiratory distress syndrome) survivors. Method A prospective cohort study of all survivors of ALI/ARDS in the PICU of Beijing Children's Hospital was performed. Patients were divided into three groups(0-3 years of age,3 ～ 7 years of age, and over 7 years of age) and followed up three months after diagnosis. Results There were 36 survivors in total of 44 ALl patients, three patients lost follow-up, 12 died and 21 survived. Five survivors refused to participate in the study because of asymptomatic, and one was unable to participate because of lymphoma com-bined with sepsis. A total of 15 children completed the whole survey (11 patients were less than 3 years old, andfour were over 7 years of age). Twelve patients had no discomfort in their respiratory tracts. Three months after be-ing enrolled, the pulmonary functions of all children improved, especially in terms of tidal volume and respiratory compliance (P<0.05). Conclusions The abnormal respiratory symptoms and signs in most children disap-peared three months after discharge. Most survivors still have pulmonary dysfunction at 3 monthes after discharge, but better than discharge.     

以人为本理念在全程护理服务中的实践

为了探索既符合中国国情又能满足病人需求的护理服务新模式，浙江省台州市中心医院自2002年开始试行全程护理服务。在实施护理中以病人为中心，从理念上、环境上、权益上、细节上为病人提供全面、全员、全程的人本服务；在管理实践中，提倡“尊、理、信、谐、通、创”六字理念，将管理视为服务，实行人本管理。通过3年的实践，整体护理质量、病人满意度、护士对工作满意度均有显著提高。     

Immunogenicity study of low-dose administration of hepatitis B virus vaccine in newborn infants: A cost reduction trial

Different doses of hepatitis B virus vaccine—prepared by Korea Green Cross Corporation, were given to healthy infants born to HBsAg-negative mothers at birth, 1 and 6 months of age. A dose of 2 μg was administered intradermally in Group A and, in the three other groups, the vaccine was given intramuscularly (i.m.). An adequate follow-up observation was possible for 9 months after birth in 22, 25, 23 and 21 infants in Groups A, B, C and D, respecvely.
Group C (5 μg, i.m.) produced seroconversion most rapidly, showing the highest rate (96%) at 9 months of age. The lowest seroconversion rate (5%) was found at the age of 1 month in Group A subjects, but the rate increased to 91% after a booster dose was given at 6 months of age.
While it can be concluded that a 5 μg i.m. dose of vaccine at 0, 1 and 6 months of age is optimum for the immunization of infants in efficacy and economy, a 2 μg intradermal dose can also be considered as an immunogenic and economical regimen, though the immune response is slower and a special technique is required for immunization.     

出国务工妇女细菌性阴道病调查结果分析

目的:了解细菌性阴道病在延边地区出国务工妇女中的流行情况。方法:用改良多胺法对延边地区586名出国务工妇女进行细菌性阴道病(BV)检测,同时用常规方法进行滴虫、霉菌检查。结果:586份阴道分泌物标本中,检出BV(+)275例,总阳性率为46.9%,其中单纯BV(+)242例(41.3%)、BV合并滴虫(+)8例(1.3%)、BV合并霉菌(+)25例(4.3%);按年龄分组,33～35岁组BV阳性率最高,为60.3%,≤20岁组最低,为20.0%。结论:延边地区出国务工妇女细菌性阴道病患病率较高,居该人群各种阴道感染的首位,无民族差异(χ2=0.22,P>0.05),但年龄差异显著(χ2=28.72,P<0.05)。因此,建议在出国体检中常规开展BV检查,以便及时发现和治疗,控制疾病传播范围。
