MRI液体衰减反转恢复序列在脑梗死中的应用

目的：研究液体衰减反转恢复（Fluid attenuated inversion recovery,FLAIR)序列在脑梗死中的诊断价值。方法：对本组30例经FLAIR序列及常规SE（自旋回波）序列、TSE（快速自旋回波）序列扫描的脑梗死患者，采用盲法读片进行对比分析。结果：共发现梗死灶：193个。FLAIR显示病灶为97％（187／193）个，其中基底节区95％（56／95个）；皮质或皮质下区99％（72／73个）；脑室旁100％（50／50个）。其他部位：81％（9／11个）；常规SE序列及TSE序列显示病灶为51％（100／193个），其中基底节区68％（40／59个），皮质或皮质下区30％（22／73个），脑室旁64％（32／50个），其他部位：55％（6／11个）。二者在显示梗死灶上存在显著差异（P＜0．01），特别是在显示皮质及皮质下病灶和脑室旁病灶上，FLAIR序列显示更化。结论：FLARI序列在脑死诊断中，较常规SE序列及TSE序列更敏感，能显示更多的病灶。     

慢性胰腺炎CT灌注表现初探

目的 探讨慢性胰腺炎的CT灌注特点.资料与方法 使用16层螺旋CT对8例慢性胰腺炎患者(慢性胰腺炎组)和71例正常对照者(对照组)进行CT灌注扫描(后处理由Philips公司提供),由两名高年资影像科医师对图像进行分析.计算各组的组织血流量(BF)、组织血容量(BV)及半均通过时间(MTT)值并采用t检验统计分析各组间灌注数据的差异.结果 (1)慢性胰腺炎组胰腺头部、体部及尾部的BF值分别为(27·6±14.0)ml·100g-1·min-1、(33.1±19.8)ml.100g-1·min-1、(47.1±13.0)ml·100g-1·min-1;BV值分别为(23.8±0.9)ml/100 g、(26.1±7.6)ml/100 g、(24.3±6.7)ml/100 g.而对照组的BF分别为(63.7±22.1)ml·100g-1·min-1、(72.6±23.3)ml·100g-1·min-1、(72.0±20.1)ml·100g-1·min-1;BV值分别为(35.8±11.8)ml/100g、(35.6±15.2)ml/100 g、(35.2±11.9)ml/100 g.统计学分析显示胰腺各部的灌注参数(BF、BV)与对照组比较,均有明显的隆低(P值均＜0.01);MTT的变化差异无统计学意义.(2)双肾、脾脏的BV值、BF值和肝脏的门静脉灌注(PVP)值与对照组比较,差导无统计学意义.结论 CT灌注成像能定量分析胰腺及其周围重要器官的血流灌注特点.慢性胰腺炎患者的胰腺血流灌注显著降低,而相邻的双.肾脏、肝脏及脾脏的血流灌注没有明显异常.

北京城、郊区儿童哮喘及相关过敏疾患的室内环境因素比较

Objective To study the indoor environmental factors associated with the prevalence of asthma and related allergies among school children.Methods A cluster sampling method was used and the ISAAC questionnaire was conducted.A total of 4612 elementary students under Grade Five of 7 schools were enrolled in the survey for the impact of indoor environmental factors on the prevalence of asthma and related allergies in several urban and suburban schools of Beijing.Results A total of 4060 sample were finally analyzed including 1992 urban and 2068 suburban.The prevalence of wheeze, allergic rhinoconjunctivitis and atopic eczema in the past 12 months was 3.1% (61/1992) ,5.3% (106/1992) ,1.1% (22/1992) among urban children while 1.3% (27/2068) ,3.1% (65/2068), 1.0% (22/2068) among suburban children respectively.The prevalence of wheeze and allergic rhinoconjunctivitis of the past 12 months in urban were both significantly higher than that in suburban ( χ2 = 14.77, 11.93, P ＜ 0.01 ).The incidences of having asthma and eczema ever among urban children (5.3% (105/1992) ,29.4% (586/1992))were significantly ( χ2 = 39.03, 147.22, P ＜ 0.01 ) higher than that among suburban ( 1.7% ( 35/2068 ), 13.8%(285/2068)).Atlthough the distributions of indoor environmental factors were similar in both areas, passivesmoking and interior decoration had different influence on the prevalence of asthma and related allergies among school children in the two areas.The significant impact of passive smoking on having asthma ever among suburban children was observed ( OR = 2.70,95% CI = 1.17 - 6.23 ) while no significant result in urban ( OR = 1.06,95% CI = 0.71 - 1.58 ); the percentage of interior decoration was 84.0% ( 1673/1992 )among urban children and 80.0% (1655/2068)among suburban children, there was significant impact of interior decoration on the prevalence of having eczema ever among urban children ( OR = 1.57,95% CI =1.17-2.10) but no significant results were found in suburban sample (OR= 1.06,95% CI =0.76-1.48).Conclusion The prevalence of asthma and related allergies among school children is much higher in urban areas than that in suburban areas and the indoor environmental factors such as passive smoking and interior decoration may differently explain the prevalence of asthma and related allergies in the two areas.     

不同针刺频度对致敏豚鼠血清总IgE影响的实验研究

目的:对针刺“大椎”治疗哮喘的时效性进行初步探讨。方法:将豚鼠随机分为空白组、模型组、每日针刺组、隔日针刺组和隔2日针刺组共5组,除空白组外均用卵清白蛋白致敏并激发哮喘。选“大椎”作为治疗穴位,以放免法检测各组血清总IgE。结果:各针刺组均可使致敏豚鼠升高的血清总IgE含量下降,但下降幅度有所差异,以隔日针刺组最为明显,与模型组相比有极其显著差异(P<0·001),其次为隔2日针刺组(P<0·01),再次为每日针刺组(P<0·05)。结论:针刺“大椎”穴使血清IgE含量明显下降,提示针刺“大椎”穴对支气管哮喘有治疗作用,且随治疗频度的不同,其疗效可能不同。
