短波紫外线照射对小儿肺炎及中性粒细胞吞噬功能和IL－2的影响

用短波紫外线照射患儿腰背部皮肤辅助治疗小儿肺炎，提示紫外线治疗组与对照组相比，显著缩短患儿发热。咳嗽及肺部湿罗音消失时间（Ｐ＜０．０１）。用化学发光法测定中性粒细胞吞噬功能，治疗组患儿血液内中性粗细胞吞噬功能显著提高（Ｐ＜０．０５）。同时测定治疗组患儿血中ＩＬ－２低于对照组（Ｐ＜０．０５），并对上述结果机理进行了探讨。

老年精神分裂症合并肺炎临床分析

目的：通过对精神分裂症合并肺炎患者和老年肺炎患者进行对照观察分析，探索老年精神分裂症合并肺炎的临床特点，为临床诊治提供资料。方法：对35例CCMD-2-R精神分裂症合并肺部感染的患者及35例同期老年肺炎患者对照分析。结果：发现老年精神分裂症合并肺炎患者与老年肺炎患者在神经精神症状和消化系统症状方面差异有显著性。结论：对老年精神分裂症合并肺炎患者更要细致观察，精心护理，早发现、早诊断、早治疗，以降低其死亡率。     

Indium-111 labelled pooled human immunoglobulin imaging to monitor the efficacy of specific therapy for Pneumocystis carinii pneumonia

Functional imaging is ideally suited to monitoring the effect of specific therapy on disease processes. In this pilot study five patients with AIDS and Pneumocystis carinii pneumonia (PCP) were imaged with Indium-111 labelled pooled human immunoglobulin (111In-HIG) during infection and after therapy for PCP. The lung activity of t t tln-HIG, measured as a lung/heart ratio, was calculated in a study performed during infection with PCP and after therapy. In all five patients the lung/heart ratio of t t 1ln-HIG was reduced after treatment. The mean reduction in heart/lung ratio was 27% (range 12%-53%). If these results are confirmed by a larger study, ¹¹In-HIG will be useful in monitoring the response of PCP to therapy in patients with AIDS.     

Persistent Hypotension Associated with Hypermedullipinemia: A New Syndrome

A new syndrome is described in a patient with advanced renal insufficiency. This consists of severe and persistent hypotension causing weakness but associated with a clear mental status. Also present is evidence for decreased vascular reactivity. The hypotension was not orthostatic. The hypotension was associated with a circulating vasodepressor substance having the characteristics of medullipin I. The medullipin appears to have been derived from the remaining right kidney. Hypotension existed despite the presence of major prohypertensive mechanisms, including an endstage kidney, hyperreninemia and hyperaldosteronemia. It is likely that hypotension due to hypermedullipinemia is an entity occurring in the human being.     

Coexisting Endogenous and Exogenous Llpold Pneumonia and Pulmonary Alveolar Proteinosis in a Patient with Neurodevelopmental Disease

We report a unique case of coexistingexogenous lipoid pneumonia, endogenous lipoid pneumonia (EU), and pulmonary alveolar proteinosis (PAP) in a 5-year-old patient with severe neurodevelop mental disease. The patient presented with gastroesophageal reflux and presumed chronic lung disease resulting from recurrent aspiration pneumonias and succumbed to respiratory failure. The autopsy showed lipid-laden macrophages and periodic acid-SchiJf9ositive granular matm'al i n alveolar spaces and multilamellated structures within both alveolar macrophages and extracellular debris.

These findings were similar to those in previous reports of coexisting E I P and PAP in the setting of gastroesophageal refux [I] . However, the present case diJfered by the presence of scattered large osmiophilic extracellular lipid vacuob. Besides strengthening the association between EIP and PAP and their relationship to gastroesophageal refux, this case suggests that t h q may arise together with exogenous lipoid pneumonia, through related mechanisms, in the setting of neurodevelopmental disease.     

Interstitial deletion of 10q: Clinical features and literature review

We report on a patient with interstitial deletion of 10q and compare her to 8 previously described patients, 2 of whom have chromosomal breakpoints similar to our patient. Minor anomalies including broad forehead, hypertelorism, strabismus, prominent philtrum, and “dysplastic” pinnae are present in our patient. Psychomotor retardation and hypotonia are universal findings in 10q interstitial deletion. Growth retardation, not present in our patient, is seen in some. These clinical findings are sufficiently distinct to suggest early chromosome studies. © 1992 Wiley-Liss, Inc.     

参附注射液对单侧输尿管梗阻大鼠肾脏肝细胞生长因子表达的影响

目的：探讨单侧输尿管梗阻后大鼠肾间质纤维化发生过程中肝细胞生长因子（HGF）的表达及中药参附注射液对其的影响。方法：采用单侧输尿管结扎（UUO）制造梗阻性肾病模型，将56只大鼠随机分为对照组（假手术组）、手术组（UUO组）和治疗组（UUO＋参附），术后7d、14d观察肾组织病理改变，应用免疫组织化学方法检测肾组织中HGF的表达。结果：与对照组相比，手术组肾间质出现了明显的纤维化，HGF的表达在术后第7天明显增加，第14天较第7天减弱，与手术组相比，治疗组肾间质纤维化明显减轻，而且HGF的表达在术后第7天明显上调，第14天较第7天上调更明显，有统计学差异（P〈0．05）。结论：参附注射液可以上调肾组织HGF的表达，减轻肾小管一间质纤维化，发挥肾保护作用。
