克罗米酚对血清雌激素和孕激素水平的影响

目的探讨克罗米酚(CC)在诱发排卵过程中对雌、孕激素水平的影响。方法采用放射免疫法,测定16例不明原因不孕妇女在自然周期和用药周期的排卵前1天和排卵后10天血清雌二醇(E2)和孕酮(P)浓度。结果排卵前1天和排卵后10天,用药周期的E2、P浓度均高于自然周期(P<0.05)。结论克罗米酚在诱发排卵过程中可导致内源激素平衡紊乱。     

结直肠癌淋巴结转移与部分肿瘤分子标志物表达的相关性研究

目的 探讨部分肿瘤相关分子标志物免疫组织化学的表达与结直肠癌淋巴结转移的相关性.方法 应用免疫组织化学技术检测65例结直肠癌手术标本Ki-67、p53的表达情况,对照手术所见和手术标本的病理检查结果 ,研究这些肿瘤相关分子标志物与肿瘤的生物学特性如浸润和淋巴结转移等的关系.结果 65例结直肠癌手术标本Ki-67、p53免疫组织化学的表达与肿瘤肠壁浸润深度无明显相关性(P＞0.05).Ki-67的表达及Ki-67标记指数的表达与淋巴结转移及Dukes分期有明显的相关性(P＜0.01);p53标记指数的表达与淋巴结转移有相关性(P＜0.05),与Dukes分期有明显的相关性(P＜0.01).结论 作为反应细胞增殖活性的肿瘤相关分子标志物Ki-67,其免疫组织化学的表达程度可间接反映结直肠癌淋巴结转移状况,可能成为反映淋巴结转移的一个标志物.     

原发性小肠肿瘤60例临床分析

目的 探讨原发性小肠肿瘤的临床特点和诊查方法。方法 回顾性分析60例原发性小肠肿瘤的临床资料、发病特点及术前诊查方法。结果 小肠肿瘤临床表现不特异，确诊时长达1周-32个月，平均6个月。术前确诊率低（31．7％）。检查方法中胃肠造影和CT的使用相对较多，受检阳性率分别为54．2％（26／48）和81．3％（26／32）。小肠肿瘤恶性居多，占53．8％（21／39）。结论 原发性小肠肿瘤表现隐匿，容易误诊，常规检查手段特异性不高，胃肠造影和CT确诊率相对较高，新的检查方法有待开发。     

成人Moyamoya病的临床表现和影像学特征

目的 总结成人Moyamoya病(烟雾病)的临床表现特点.比较MRA与DSA在Moyamoya病诊断中的价值.方法 对经DSA或MRA确诊的8例成人Moyamoya病患者的临床及影像学资料进行回顾性分析.结果 脑卒中是本组Moyamoya病患者最常见的临床表现,缺血性卒中与出血性卒中发病各半.MRA与DSA检查显示所有患者均有颈内动脉或其分支狭窄或闭塞及脑底异常血管网形成,两者结果相符合.结论 对年轻无基础疾病的脑血管病患者,尤其反复TIA或卒中或头痛患者,应常规行MRI和MRA检查.DSA可清晰显示颅内、外侧枝循环状况,更有助于手术适应证的选择与预后评价.     

A comparative study on therapeutic method of traumatic epidural hematoma

Objective： To explore the therapeutic methods, surgical indications and clinical practice of minimally invasive surgery on traumatic epidural hematoma （EDH）. Methods： Retrospective study was made on 135 patients with traumatic EDH admitted into our hospital from June 2002 to August 2005. Sixty-five patients were treated with mini-invasive negative pressure drainage （treatment group）, 70 patients with comparable condition used traditional craniotomy （control group ）. The mean time of operation, average days in hospital, expenditure and prognosis of two groups were recorded and analyzed. Results： There was no significant difference in therapeutic efficacy between two groups. Patients in treatment group had a shorter hospital stay and less expenditure than those in control group. Conclusion： Mini-invasive negative pressure drainage is simple, effective, economical and applicable to some traumatic EDH patients.

THE TREATMENT OF SPINAL CORD INJURY CASES BY MEANS OF SPINAL OMENTUM TRANSPOSITION

Omentum transposition to cervical spinal cord for the treatment of traumatic cervical spinal cord myelopathy.In treating spinal cord injury, the clinic of cervical spinal cord injury has to face the problems of tetraplegia and control of Respiration. The application of various kins of treatment include skull traction, laminectomy, intervebral bone graft fusion and omen turn spinal cord transposition. We have treated 10 cases in the period from June, 1986 to June, 1983. The discussion will focus on the Oinentum transposition to cervical spinal cord and the related problems of cervical spinal cord injury.     

Effect of fathers'' age and birth order on occurrence of congenital heart disease.

STUDY OBJECTIVE--The aim was to examine if there is an effect of fathers' age and of birth order on the occurrence of congenital heart disease. DESIGN--This was a hospital based case-referent study including use of birth defects surveillance data. SUBJECTS--Subjects were 497 cases of congenital heart disease aged between 3 months and 5 years, born in Beijing and Hebei Province, China; 6222 children without congenital heart disease serve as reference baseline. MEASUREMENTS AND MAIN RESULTS--With stratified analysis and logistic regression analyses, congenital heart disease was found to be associated with fathers' age less than 25 years (odds ratio 2.63), independent of mothers' age and of birth order. There was also evidence to show a higher birth order effect on the occurrence of congenital heart disease independent of parental ages. CONCLUSION--Higher birth order and fathers aged less than 25 years were both independently associated with some categories of congenital heart disease and with congenital heart disease overall.
