彩色多普勒血流显像(CDFI)评价胎儿生长发育状况

目的阐明CDFI对评价胎儿宫内状况的可行性。方法200例经普通B超检查的胎儿,按测量各项常规指标的数值分为正常组100例和异常组100例,再分析经CDFI检查,所测定的指标包括胎儿大脑中动脉、肾动脉、胎盘床动脉、脐动脉血流搏动指数(PI)、阻力指数(RI)及脐动脉的收缩与舒张期峰值速率之比(S/D)。对其结果做详细记录,并进行统计学分析。结果正常组100例,经CDFI检查亦正常;胎儿出生时体重在2500g以上,新生儿发育正常。另100例异常组经CDFI检查各项指标中,54例正常,46例异常;胎儿出生时体重均小于2500g,其中54例新生儿虽体重较正常儿偏小,但发育正常;另46例胎儿宫内窘迫,导致导常分娩、新生儿生存率低。结论彩色多普勒血流显像对了解胎儿宫内情况有着重要的作用,是产科检查监护中不可缺少的部分。     

胰岛素使用方法的研究进展

胰岛素治疗是糖尿病治疗的重要内容,也是使糖尿病患者血糖达标的有效方法。严格的血糖控制对糖尿病慢性并发症的预防和延缓发生有重要意义,然而目前各国的糖尿病血糖控制达标率均不足50%。患者甚至包括医生对低血糖的恐惧是启动胰岛素治疗和达到最佳胰岛素治疗的主要障碍之一。     

1996-2004年郑州市围产儿总唇裂畸形动态变化分析

目的了解郑州市围产儿总唇裂畸形的发病情况及年度和城乡分布的特点。方法采用以医院为基础的监测方法收集资料，调查郑州市14所医院内住院分娩的孕28周一产后7天的围产儿。结果郑州市围产儿总唇裂发生率为15．12／万，其中唇裂为4．82／万，唇裂合并腭裂为10．29／，城镇发生率为13．37／万，乡村为20．15／万，男性为16．08／万，女性为13．92／万，总唇裂产妇年龄组别发生率差异有显著性，在≥35岁年龄组最大。年度发生率无长期趋势。总唇裂以单发形式多见，占91．54％，总唇裂畸形围产期病死率为25．87％，单发畸形为22．28％，多发畸形为64．71％。结论郑州市总唇裂发生率无下降趋势，乡村高于城镇。     

B超引导下经皮肺穿刺针吸活检对周围型肺肿块的诊断价值

目的探讨Ｂ超引导下经皮肺穿刺针吸活检对周围型肺肿块的诊断价值。方法对３１例患者施行Ｂ超引导肺穿刺针吸活检５６次，进行细胞学和细菌学检查。结果穿刺取材成功率为９３．６％，所获细胞学资料与手术病理诊断或临床治疗随访对照，定性诊断符合率为８９．７％。结论该诊断方法简便实用，并发症轻微，适于临床推广应用。     

心理因素对小学生脑力工作能力影响的研究

采用横断面研究方法，对180名小学三年级学生脑力工作能力与其智力、性格、学习动机等心理因素和学习、睡眠时间等作息因素的关系进行分析研究。验证了学习、睡眠时间是影响学生脑力工作能力重要的外部因素；脑力工作能力与智力和学习成绩呈正相关。学生自身的心理因素中，学习动机对脑力工作能力有重要影响，所以激发和强化学生的学习动机，是保持和提高学生学习工作能力的有效手段；而性格内外向性、情绪稳定性等因素，对脑力工作能力的影响不明显。     

The effect of ethanol intake on tendon healing: a histological and biomechanical study in a rat model

Introduction  

Ethanol has a suppressive effect on inflammation and the immune system, but the effect of ethanol on tendon healing in vivo has not been studied. The purpose of this study was to investigate the histological and biomechanical effects of ethanol intake on tendon healing in a rat tendon injury model.     

Some new clinical applications of rhinomanometry

Clinical applications of active anterior rhinomanometry of the oscillation type had been carried out for the purposes other than the conventional uses of rhinomanometry. 1. Effect of acupuncture upon the nasal resistance to airflow: Among 8 acupuncture points which were recorded in Chinese traditional medical literatures as effective for improving nasal breathing, Ingxiang point had been proved to possess definite effect of lowering the nasal resistance to air-flow in patients with congestion of nasal mucosa, whereas in other acupuncture points this effect was not certain. 2. The severity of snoring before and after treatment could be determined objectively by the measurement of nasal resistance to air-flow and the breathing pattern of the patient.
