放免法检测乙型慢性活动性肝炎病人红细胞C3b受体的研究

用放免法检测乙型慢性活动性肝炎病人的红细胞ｃ３ｂ受体（ＫＢＣＣＲ１）．结果：病人ＲＢＣＣＲ１明显低于献血员（Ｐ＜０．０５）；抗－ＨＢｓ特异性免疫复合物阳性病人ＲＢＣＣＲ１明显低于阴性病人（Ｐ＜０．０１），与红细胞Ｃ３ｂ受体花环试验检测结果一致。表明乙型慢性活动性肝炎病人ＲＢＣＣＲ１数量减少，活性下降。其原因可能是特异性循环免疫复合物占据了ＲＢＣＣＲ１空位，使ＣＲ１活性下降。

目的：了解肺炎克雷伯菌肺炎的发病现状和对抗生素的耐药性及其治疗。方法：采用回顾性分析我院于2001年1月－2002年6月住院肺炎克雷伯杆菌肺炎50例的发病，对抗生素耐药性及其治疗。结果：患多见于中老年男性，临床表现以发热、咳嗽、咳痰多见。结果：肺炎克雷伯杆菌对抗生素具有多重耐药性，耐药率为氨苄西林100％，替卡西林96％，阿莫西林／棒酸54％，头孢西丁46％，庆大霉素44％，培福沙星42％，头孢他定38％，未发现对亚胺培南的耐药菌株。结论：肺炎克雷伯杆菌肺炎临床表现无特殊性，亚胺培南对肺炎克雷伯杆菌的耐药率最低，应作为治疗重症肺炎克雷伯杆菌肺炎首选用药。     

Climatic factors and Pneumocystis jiroveci infection in southern Spain

The modes of infection and transmission of Pneumocystis jiroveci remain unclear. This study explored the relationship between the incidence of infection and climatic factors. In total, 536 cases of P. jiroveci infection were identified in the period 1994-1998, with an inverse correlation between the incidence of Pneumocystis pneumonia and the minimum mean ambient temperature (Spearman correlation coefficient: r - 0.30; p 0.02; ARIMA model: r - 0.250, p 0.07). The highest number of cases occurred in winter (anova test, p < 0.05), and there was a clear season-related incidence of P. jiroveci infection.     

中西医结合早期干预对SARS肺部炎症的影响

[目的]以X线胸片为主要观察指标,对中西医结合治疗SARS的临床疗效进行客观评价,为SARS临床筛选有效的干预方案提出科学依据。[方法]采用多中心前瞻性队列研究的方法,通过对参加国家863重大项目“中医结合治疗SARS临床研究”的北京地区11家医院361例确诊SARS患者的1561张X线胸片的研究,阐明中西医结合治疗对SARS肺部炎症的影响。[结果]从总体疗效来看,X线胸片总积分西医组平均为5.85±6.5。中西医结合组为6.67±7.61;普通型西医组为4.79±5.6。中西医结合组为5.40±6.86;重型西医组为7.67±6.34,中西医结合组为8.16±7.60,以上两组间比较均未见显著性差异 (P>0.05)。但发病7d内开始干预的胸片总积分西医组平均为6.39±6.48、中西医结合组为4.40±4.97,中西医结合组X线胸片总积分明显低于西医组 (P=0.0004);普通型西医组为4.59±5.22、中西医结合组为3.99±4.67,两组间比较未见显著性差异 (P=0.12);重型西医组为9.14±7.24、中西医结合组为5.30±5.48,组胸片总积分明显低于西医组(P=0.034);说 明发病7 d内对SARS患者进行中西医结合治疗,肺部炎症的吸收明显优于西医组,总体疗效与重型患者的疗效均具有统计学意义。[结论]中西医结合早期干预对SARS肺部炎症吸收的临床疗效具有明显的优势。     

Erythema multiforme during cytomegalovirus infection and oral therapy with terbinafine: a virus–drug interaction

The authors report a case of erythema multiforme in a 32-year-old woman who was also taking oral terbinafine for an onychomycosis. The patient data analysis showed serological positivity for cytomegalovirus (IgM and IgG) and hepatitis C virus and serological titre of antinuclear antibody was elevated. After a brief review of the literature the authors propose the possibility of virus-drug interaction as a model of adverse drug reactions.

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。     

Autopsy findings in two cases of neonatal herpes simplex virus infection: detection of virus by immunohistochemistry, in situ hybridization and the polymerase chain reaction

We describe the pathological findings in two fatal cases of neonatal infection with herpes simplex virus. One had an encephalitis caused by herpes simplex virus type 2 (HSV-2); the other had a disseminated infection with herpes simplex virus type 1 (HSV-1). Confirmation of the diagnosis was obtained by use of the polymerase chain reaction to amplify viral DNA from paraffin sections of autopsy tissues. By using primers which amplify fragments of the HSV-1 thymidine kinase gene and HSV-2 glycoprotein gene respectively it was possible to discriminate between infection with HSV-1 and HSV-2. In contrast, immunohistochemistry and in situ hybridization using commercially available reagents did not distinguish between HSV-1 and HSV-2 infection. However, immunohistochemistry and in situ hybridization are probably more reliable than the polymerase chain reaction for assessment of the distribution of virus in different tissues.     

病毒性肝炎病人血浆VitE水平及其临床意义

观测了急性肝炎和重症肝炎病人血浆ＶｉｔＥ及Ｌｐｏ水平及其动态变化。急性肝炎和重症肝炎病人血浆ＶｉｔＥ低于对照组，Ｌｐｏ高于对照组，均以重症肝炎更明显，且死亡病例血浆ＶｉｔＥ低于存活者。部份病人口服ＶｉｔＥ不能提高其血浆水平，并随病情加重而逐渐降低。讨论了病毒性肝炎病人血浆ＶｉｔＥ降低与Ｌｐｏ升高的关系及其临床意义，认为动态观测血浆ＶｉｔＥ可作为判断重症肝炎病情进展及预后的参考。
