Developing policy in the provision of parenting programmes: integrating a review of reviews with the perspectives of both parents and professionals

Background   Parenting programmes are a key component of the delivery of children's services, but evidence-based policy has often proved difficult to implement.
Methods   The present review addressed this issue by integrating a review of systematic reviews of parenting programmes and a series of focus groups with parents and professionals involved in parenting across three agencies in a regional area (health, education and social work). The review summarizes parenting interventions targeting infant mental health, emotional and behavioural difficulties, autism spectrum disorder and attention deficit hyperactivity disorder, abuse/neglect, alcohol/substance abuse and 'vulnerable' parents. The focus groups discussed topics such as the range of parenting services across the three agencies, accessibility, gaps in the service and future directions.
Results and conclusions   Twenty systematic reviews were summarized. These reviews demonstrated that there is a wide range of parenting programmes available that have the potential to benefit families who are affected by problems ranging from emotional and behavioural difficulties to adolescent substance abuse. However, the findings of the focus groups reveal that the success of these programmes will depend in part on how they can be tailored to meet the social context of the families targeted. These integrated findings are discussed in terms of their implications for policy and practice.     

车间空气中石棉纤维卫生标准的研制

在上海、苏州、北京及四川的石棉厂矿进行了长期的职业流行病学调查，分别取得各厂矿石棉尘重量浓度与石棉纤维计数浓度的换算关系，进而计算各厂矿工人接触石棉计数剂量与石棉肺发病的剂量－反应关系，并按工人平均接尘３５年计，推算出将患病率控制在１％时的容许浓度。上海和苏州两厂调查中，工人接尘浓度已计算成时间加权平均浓度；北京和四川二厂矿则用瞬时浓度。据此制订的车间空气中石棉纤维卫生标准为：最高容许浓度１．５ｆ

肾综合征出血热特异性抗体的检测与中西医结合治疗的研究

目的探索一种更为简便、快速、特异、灵敏的肾综合征出血热(hemorrhagic fever with renal syndrome, HFRS)抗体的检测方法及更为有效的中西医结合治疗手段.方法559例HFRS患者血清同时采用免疫滴金法(colloidal gold immuno-dot assay,CGIDA)与酶联免疫吸附法(enzyme linked immunosorbent assay,ELISA)对比检测特异性免疫球蛋白M抗体(抗HFRS-IgM),间接免疫荧光法(indirect fluorescent antibody test,IFAT)对比检测特异性免疫球蛋白G抗体(抗HFRS-IgG).101例HFRS患者分组进行中西医结合治疗,治疗组50例用苦黄注射液、参麦注射液联合黄芪口服液,对照组51例用利巴韦林注射液联合甘利欣注射液,针对老年患者的临床特点,及早采用综合性防治措施.结果559例HFRS患者血清,以CGIDA法检测抗HFRS-IgM,阳性396例(70.8%);以CGIDA法检测抗HFRS-IgG,阳性489例(87.5%).治疗组与对照组用药后退热天数、主要症状和体征缓解天数相似(P＞0.05);肾功能恢复天数,对照组优于治疗组(P<0.01);在越期方面,治疗组越休克期数明显高于对照组(P<0.01). 结论CGIDA法检测HFRS特异性抗体分别与ELISA法及IFAT法对照,均有简便、快速、特异、灵敏之优点,检测抗HFRS-IgM,CGIDA法敏感性差于ELISA法,但是无假阳性;检测抗HFRS-IgG,CGIDA法的灵敏度高于IFAT法.苦黄注射液、参麦注射液联合黄芪口服液与利巴韦林注射液联合甘利欣注射液相比较,疗效无明显差别,但前者优于改善休克情况,后者强于改善肾功能.

Vasomotion in rat diaphragm microcirculation at rest and during stepwise arterial pressure reduction

The effect of haemorrhagic hypotension on the incidence, frequency and relative amplitude of vasomotion in rat diaphragm microcirculation was assessed by laser Doppler flowmetry (LDF). Graded bleeding to four hypotension levels (80, 60, 40 and 30% of the control state) were performed in 24 Sprague–Dawley rats. The incidence of vasomotion was 83% in the control state, 96% at the 80% level, 100% at the 60% level, 96% at the 40% level, and 46% at the 30% level. The median fundamental frequency of vasomotion determined manually during the control state and at the hypotension levels (in descending order) was 4.11 (range, 3.29–5.58) cycles min^?1 (cpm), 4.48 (3.21–5.92) cpm, 4.20 (3.5–5.56) cpm, 4.01 (3.33–5.36) cpm, 3.71 (3.25–4.49) cpm (P < 0.01 from the fundamental frequency at 80 and 60% hypotension levels). The median relative amplitudes determined manually during the control state and descending hypotension levels were 44.5% (range, 24.9–135.9%), 69.4% (26.6–147.2%), 84.0% (40.3–177.1%) (P < 0.01 from resting and last stage of bleeding), 90.40% (26.2–189.6%) (P < 0.01 from resting and last stage of bleeding), 69.2% (35.6–93.2%). We concluded first that during the resting condition, vasomotion was frequently present in diaphragm microcirculation, which is distinct from other vascular beds of skeletal muscles. Second, the relative amplitude of vasomotion during haemorrhagic hypotension plotted against decreasing blood pressure exhibited a reverse U-shaped curve with a maximum at 40–60% of the control blood pressure, while the frequency of vasomotion remained relatively constant until the last stage of haemorrhage and centred around 3–5 cpm.
