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。

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.     

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。     

Richard钉治疗股骨粗隆间骨折

目的：报告在不使用C型臂X线机的情况下，应用Richard钉治疗股骨粗隆间骨折经验，并对治疗结果进行评估。方法：33例股骨粗隆间骨折均采作一次摄片导针定位行Richard钉内固定手术。结果：33例随访6月-3年骨折全部愈合，无螺钉穿破股骨头，无钉板、螺钉断裂。无螺钉退出，无骨折畸形愈合，3例行走活动时有轻微疼痛，全部病例均无髋关节活动受限。结论：该方法定位准确、操作方便、固定可靠、允许早期活动、功能恢复快、并发症少，特别适合无C型臂X线机的基层医院推广应用。     

前臂逆行骨间背侧皮瓣的临床应用

目的总结前臂逆行骨间背侧皮瓣的临床疗效。方法回顾性分析42例前臂逆行骨间背侧皮瓣，并结合文献阐明其变异程度及变异的处理。结果骨间背侧血管在前臂中1／3缺如1例．皮瓣边缘坏死；皮瓣向近端延伸超过4cm者4例，远端坏死，延迟愈合；其余均一期愈合：结论虽然前臂骨间背侧血管有变异，但前臂逆行骨间背侧皮瓣仍是修复手背中等大小创面较为理想的方法，以近点皮肤穿支向近端延伸皮瓣不要超过4cm。
