不同采血针对新生儿足跟采血成功率的影响

目的：探讨不同采血针在新生儿疾病筛查采血中的采血效果。方法：采用三种采血针分别对2126例（A组）、1786例（B组）、1471例（C组）新生儿进行足跟采血，比较其采血成功率。结果：A、B、C三组之间差异有统计学意义（P〈0．01）。结论：采用7号一次性注射针头采血（C组）可明显提高采血成功率。     

小儿输尿管开口异位的诊断和治疗(附22例报告)

目的 提高小儿输尿管开口异位的诊治效果。方法 总结22例输尿管开口异位患儿临床资料。男1例，女21例。年龄1个月～12岁，平均4岁。单侧17例，双侧5例。21例女童中，有正常分次排尿伴异常漏尿18例，完全持续性漏尿3例；1例男童有上尿路梗阻及泌尿系感染。异位开口于阴道14例、尿道4例、前庭3例、膀胱颈1例。结果 手术治疗20例，其中肾切除者11例、半肾切除者7例，术后漏尿症状消失，3例合并输尿管残端综合征；1例双输尿管膀胱再植术后仍有尿失禁；1例直肠化膀胱术无漏尿症状。结论 明确诊断，选择合理手术是小儿异位输尿管口治疗成功的关键。     

在深静脉血栓—肺栓塞病程中腔静脉滤器的应用价值分析

目的：探讨腔静脉滤器(Vena cava filter VCF)在深静脉血栓(Deep venous thrombosis DVT)—肺栓塞(Pulmonary embolism PE)病程中的应用价值。方法：结合本组25例高危深静脉血栓一肺栓塞患者，对其中24例置放5种构型的永久型或临时型下腔静脉滤器(IVCF)26枚的临床疗效、影响病程与预后因素及病生理改变，复习文献分析讨论。结果：DVT有可能脱落导致PE或致死性肺栓塞；置放IVCF可有效预防肺栓塞，早期进行溶栓治疗，改变预后。结论：严格按适应证植入IVCF，对DVT—PE的早期治疗和预防致死性肺栓塞有重要意义，但其应用价值需进行综合评价和进一步探讨。     

Regression of Pulmonary and Multiple Skeletal Metastases from Renal Cell Carcinoma by Nephrectomy and Alpha-interferon Therapy: A Case Report

We report a rare case of advanced renal cell carcinoma in apatient who showed complete resolution of metastases to thelung and bones after nephrectomy, partial jejunectomy and subsequentalpha-interferon therapy. The patient was a 54-year-old manwhose right lung and left femur metastases were detected beforenephrectomy. In the seventh week after nephrectomy, a partialjejunectomy was carried out because of the obstructive ileuscaused by intraluminal multiple metastases of the jejunum. Apathological fracture of the metastasized right humerus occurredsubsequently. After four months of intramuscular alpha-interferonadministration (3x106 units/day), however, x-rays revealed thecomplete disappearance of the metastatic lung shadow and a solidunion of the humerus, and there were no tumor cells in the femurspecimen resected at the subsequent reconstruction surgery ofthe left leg. Seven years have passed from onset, and the patientis still alive and disease free.     

胸部高分辨率CT检查技术的临床应用

笔者对５０例肺部疾病胸部常规ＣＴ和高分辨率ＣＴ（ＨＲＣＴ）图像进行了对照分析。其中特发性肺间质纤维化（ＩＦＰ）８例，肺转移癌５例，支气管扩张１５例，慢性阻塞性肺气肿１５例，周围型肺癌７例，结果表明：ＨＲＣＴ在ＩＦＰ、支气管扩张和肺气肿的显示明显优于常规ＣＴ（Ｐ＜０．００１），在对肺部原发或转移性肿瘤的显示能提供更多的诊断信息。笔者还讨论了ＨＲＣＴ的检查技术和图像后处理，分析了影响ＨＲＣＴ的若干因素，指出通过缩小视野（ＦＯＶ），减少象素做图像的重建放大显示肺部局部结构更为清楚方便，应灵活运用。     

完全性肺静脉异位引流的手术治疗经验

为评估影响完全性肺静脉异位引流（ＴＡＰＶＤ）手术纠治的因素，本组纳入了２８例在中度低温体外循环和１５例在深低温停循环下手术纠治者。结果手术死亡４例，死亡率９．３％。随访３２例，２例肺静脉回流梗阻分别于术后５个月和２年３个月死亡。结论认为，ＴＡＰＶＤ必须早期手术防止肺血管阻塞性病变；术后定期随访；改进手术方法，防止心房内补片粘连所致肺静脉回流梗阻。     

Periodontal conditions among the middle-aged and the elderly in Hong Kong

Abstract The aim of this study was to describe the periodontal conditions in 372 35–44-yr-old and 537 noninstitutionalized 65–74-yr-old Hong Kong Chinese who were examined clinically for loss of attachment, recession, probing depth, calculus, and bleeding after probing. Community Periodontal Index (CPI) data and treatment need indications were compiled from index teeth or their substitutes. The prevalence of loss of attachment varied considerably in both cohorts according to the definition of the threshold (≥6, ≥9, and ≥12 mm, respectively). The mean numbers of teeth with loss of attachment at the ≥6-mm threshold and at higher thresholds were small. In both age cohorts, about one-fifth of subjects had probing depths ≥6-mm, while al the ≥9-mm threshold only 2–3% were so affected. Although recession was an important component of loss of attachment in the younger cohort, in the older cohort the prevalence and extent of recession were greater than for probing depths at thresholds ≥4 mm. All subjects had one or more teeth with calculus, bleeding, or both, most teeth being so affected. Eighty-four of the 537 65–74-yr-old subjects were excluded either because of edentulousness or because extractions indicated for the remaining teeth would have rendered the subjects edentulous. The distribution of subjects according to their highest CPI score was remarkably similar for the two cohorts. No subjects in either age group were assessed as “healthy” (CPI code 0) or had “bleeding only” (code 1) as their highest score. While most subjects scored CPI code 2 or 3 us their highest score, only 17% of the younger and 15% of the older cohort scored Community Periodontal Index of Treatment Needs (CPITN) code 4. Differences in the mean number of sextants affected by CPI codes between the two cohorts were mainly due to a greater number of excluded sextants in the older cohort. CPI findings for 35–44-yr-olds differed little from those reported in 1984.
