自然流产患者滋养细胞肝素表皮生长因子的表达及意义

目的　探讨自然流产患者滋养细胞肝素表皮生长因子 (HB EGF)的表达及其与滋养细胞增殖细胞核抗原 (PCNA)的关系。方法　选择自然流产患者和正常妊娠者各 2 0例 ,采用免疫组织化学法分析滋养细胞HB EGF和PCNA的表达。结果　HB EGF主要存在于细胞质 ,合体滋养层和细胞滋养层均有表达 ,部分流产滋养细胞不表达。自然流产患者滋养细胞HB EGF和PCNA的表达显著低于正常妊娠者 (P <0 .0 1) ,成正相关 (r =0 .4 5 4 ,P <0 .0 1)。结论　HB EGF的表达和滋养细胞增殖相关 ,HB EGF下降可能与自然流产的发生相关     

糖皮质激素治疗急性呼吸窘迫综合征58例临床分析

目的 评价糖皮质激素在急性呼吸窘迫综合征（ARDS）救治中的作用。方法 回顾性分析我院1992年8月－2001年5月58例临床确诊为ARDS患的临床资料，其中肺内型ARDS组（ARDSp）18例，肺外型ARDS组（ARDSexp)40例。各组再以使用地塞米松情况分为：≥30mg/d组，＜30mg/d组和非激素治疗组。结果 各组病情程度相当，组间APACHE Ⅱ评分比较差异无显性（P＞0．05）。激素用量≥30mg/d组与＜30mg/d组及非激素治疗组比较，病情改善天数及使用呼吸机治疗天数均明显缩短，差异有显性（P＜0．01）。58例患总病死率为20．7％，ARDSp组，ARDSexp组中激素用量≥30mg/d组的病死率分别为14．3％，11．5％，均低于ARDSp与ARDSexp组的平均病死率（分别为22．2％，20．0％）。所有病例未见感染扩散或加重。结论 早期，足量，适当疗程应用糖皮质激素治疗ARDS可及时逆转过度失控的炎症反应，缓解病情，降低病死率。

超声心动图对62例房间隔缺损封堵术后心功能变化的评价

目的：应用超声心动图评价房间隔缺损(ASD)封堵术前后左、右心室功能的变化。方法：对62例成功施行经皮穿刺ASD封堵术的患者进行研究。所有患者在术前、术后1周及1个月分别进行超声心动图检查．观察心脏大小及功能的改变。结果：ASD封堵术后，左室舒张末期前后径、左室舒张末期容积、左室每搏量及左室射血分数增大，而左室收缩末期容积未见明显改变；右室舒张末期前后径、右室舒张末期容积、右室收缩末期容积、右室每搏量、右室射血分数及右室心肌工作指数均减小。结论：经皮穿刺ASD封堵治疗既可减轻右室容量负荷，改善右室功能，也可改善左室的收缩功能：超声心动图对ASD封堵前后心脏血流动力学评价及疗效的观察起了重要的作用。     

双源CT低剂量前瞻性心电触发序列扫描在冠状动脉血管成像的应用

Objective To evaluate low-dose CT coronary angiography with prospective electrocardiogram (ECG)-triggering using dual-source CT scanner.Methods Sixty-eight patients who underwent coronary CT angiography using a dual-source CT scanner were divided into 2 groups: group A (38 cases) and group B (30 cases).Prospective ECG-triggering sequence scan mode was employed for group A.Inclusion criteria included: heart rate <70 bpm, sinus rhythm, and heart rate fluctuation less than 10 bpm.Data acquisition was set at 70% of the RR-interval.Retrospective ECG-gating helical scan was performed for group B.Inclusion criteria included heart rates < 70 bpm and sinus rhythm.The exclusion criteria included heart failure and serious arrhythmias.In both groups, patients with a BMI≥24 kg/m2 were examined with a tube voltage of 120 kV, whereas patients with a BMI <24 kg/m2 were examined with a tube voltage of 100 kV.All images were transferred to a workstation for further processing and analysis.The imaging quality was evaluated.The imaging quality of coronary artery segments were compared with rank sum test between the two groups, and the radiation dose were compared with t test.Results A total of 476 coronary artery segments were evaluated in group A and 372 segments were evaluated in group B.The mean score of imaging quality for coronary artery segments in group A was 3.48±0.59 and that in group B was 3.53±0.58.There was no statistical difference in imaging quality between the two groups (Z=-1.432, P=0.187).The effective dose was on average (2.51±0.54) mSv (range 1.3--3.3 mSv) in group A, whereas on average (14.55±3.54) rosy (range 7.1--20.2 mSv) in group B.There was a statistical difference between the two groups (t=18.484, P=0.000).Conclusions Low-dose prospective ECG-triggering sequence scan in dual-source CT coronary angiography is feasible in patients with low heart rate and regular cardiac rhythm.This scan mode can substantially reduce radiation doses while preserving good diagnostic image quality.     

蔓菁与蔓菁子

蔓菁又名芜菁,古时也称作葑,为十字花科二年生草本植物。原产于我国,在《诗经·唐风》中记有:“采葑采药,首阳之东。”据《广群芳谱》记载:“根长而白,形如胡萝卜,霜后特软美,蒸煮煨任用,稍似芋魁,含有膏润,颇近谷气,茎粗叶大而厚阔,夏初起苔,开黄花,四出如芥,结角亦如芥子,紫赤色……四时皆有,四时皆可食,春食
