Pulmonary Sequestration In A Child With Acute Myelold Leukemia

The article describes a relatively rare congenital anomaly that was difficult to diagnose in a 10-year-old child with acute nonlymphoblastic leukemia. Just at diagnosis of leukemia, the patient showed a pathologic chest radiograph because of a parenchymal thickening at the right lung apex. The presence of bronchopneumonia was suspected, and broad-spectrum antibiotic therapy was started with subsequent antifungal treatment for persistent fever and concurrent chemotherapy-induced marrow aplasia, which did not favor pulmonary infiltrate recovery. Continuous culture tests, including bronchial swab, proved negative for Koch-Weeks bacillus, fungal organisms, and other pathogens. Computed tomography, however, was suggestive of Aspergillus lung involvement, and apical sepmentectomy was performed. The anatomic pathologist suggested the diagnosis of intralobar sequestration. In summary, when pulmonary pathology with an excavation is found in a leukemic child, one must consider the possibility of pulmonary sequestration complicated by an infectious disease.     

双相气道内正压呼吸机在老年慢性阻塞性肺疾病康复期和急性肺水肿患者中的临床应用

应用双相气道内正压呼吸机（ＢｉＰＡＰ）对９例慢性阻塞性肺疾病（ＣＯＰＤ）康复期和呼吸衰竭稳定期进行临床观察发现，治疗后动脉血氧分压与治疗前相比显著升高（Ｐ＜０．０１）；肺活量及用力肺活量轻度升高；１例３次发生急性左心衰、急性肺水肿致急性呼衰患者治疗后，病情很快改善；１例阻塞性夜间睡眠呼吸暂停综合征者应用效果满意。该机应用简便、安全，对心率血压无明显影响，为ＣＯＰＤ康复期、急性左心衰兼肺水肿的治疗提供了新途径。     

中西医结合治疗肺心病心律失常40例疗效观察

为提高肺心病心律失常的临床疗效,采用中药清肺化痰活血剂配合抗菌素及氧疗法对40例肺心病并发心律失常患者进行了治疗观察,同时与单纯使用抗菌素及氧疗法治疗的40例患者进行对照。临床以心电图改善情况为观察指标,结果两组有效率分别为87.5％和67.5％。Ridit分析结果表明,治疗组疗效明显优于对照组,经显著性检验,两组差异显著(P<0.05)。     

活动性结核标志物'H-多肽的实验与临床研究

本题研究是经免疫学途径直接检测人体感染结核菌的情况，为现代结核病的实验诊断、临床监测、流行病调查提供了一个全新的检验指标。作者首先发现了一种仅存在于活动性结核病患者体液中的蛋白成份—活动性结核标志物（ＡｃｔｉｖｅＴｕｂｅｒｃｕｌｏｓｉｓＭａｒｋ—ＡＴＭ）１Ｈ—多肽；并为之创立了独特的检测方法，经四年多临床１９４６０例样本调查中确定了ＡＴＭ的临床价值。将ＡＴＭ检测与ＯＴ皮试、酶联免疫ＥＬＩＳＡ、ＤＮＡ探针、ＰＣＲ基因扩增技术及典型病例组患者行Ｘ线计算机断层摄影（ＣＴ）、磁共振像（ＭＲＩ）等多组对比试验中，实验与临床研究资料分析证明：ＡＴＭ检测的总敏感度为８６．０６％、特异度９６．２４％、准确度９３．４５％、诊断效率为８２．８２％、批内ＣＶ１．２％、批间ＣＶ２．０％、Ｐ＜０．０５。经ＮＭＲ光谱分析结构含有ＣＣＨ２官能团。     

肺部疾病中痰巨噬细胞对结核菌素试验反应的临床研究

目的:测定肺结核、肺肿瘤及非特异性炎症患者注射结核菌素前后痰巨噬细胞的不同数量变化,由此提供一种新的鉴别诊断方法。方法:皮内注射结核菌素、收集注射前、后痰液,测定痰巨噬细胞在不同时间的数量变化。结果:肺结核病人在结核菌素试验后痰巨噬细胞明显增加,肺部肿瘤及非特异性炎症则无显著性变化。结论:肺部患者测定结核菌素前后痰巨噬细胞变化,可作为菌阴肺结核与肺部肿瘤及非特异性炎症鉴别诊断依据之一。     

Constitutional heteromorphism of 9q13→q21 in a patient with chronic myelogenous leukemia

An apparently balanced de novo reciprocal translocation t(5;21) (q13;q22) was demonstrated in a girl with acrobrachycephaly, ventriculomegaly, pulmonary stenosis and anal malformation. The possible relationships between her karyotype and malformations are discussed.     

Morphometric analysis of the great vessels in early fetal life

Pathological examination of the heart and great vessels wasperformed in 61 specimens obtained after surgical terminationof pregnancy for psychosocial indications at 9–18 weeksof gestation. The aorta and pulmonary trunk were identifiedand external diameters were measured at the level of, and distalto the aortic valve and pulmonary valve, the level of the aorticisthmus and thoracic aorta, and the proximal and distal ductusarteriosus. All eight vessel diameters increased linearly withgestational age and the ratio of the diameter of the aorticisthmus to that of the aortic valve or the distal ductus arteriosusalso increased with gestation. Early pregnancy is characterizedby rapid growth of the fetal head and this may well be the consequenceof a preferential distribution of left ventricular output infavour of the head due to relative narrowing of the aortic isthmusat this gestation.     

Video-assisted thoracoscopic wedge resection of solitary pulmonary metastasis from hepatocellular carcinoma

We report a metastatic pulmonary tumor resected by video-assisted thoracoscopic surgery. A 63-year-old female was found to have four nodules of hepatocellular carcinoma (HCC) in January 1991; after non-surgical treatment, the tumors had become necrotic. In June 1992, a new HCC nodule was found. After infusion chemotherapy, it became necrotic. In September 1993, a solitary lung tumor, 2.4 cm in diameter, appeared at the periphery of the right lung. Because the tumor was considered to be a metastatic HCC rather than a primary lung cancer, it was removed by thoracoscopic wedge resection. Although whether metastasectomy contributes to prolongation of survival is still controversial, thoracoscopic pulmonary resection may be indicated for solitary peripheral metastasis, if the primary HCC is well controlled by multidisciplinary treatment.
