132例艾滋病合并卡氏肺孢子虫肺炎的诊治

卡氏肺胞子虫肺炎（PCP）是艾滋病（AIDS）患者最常见的机会性感染之一，也是最主要死亡原因之一。随着我国艾滋病病毒（HIV）感染者和AIDS患者的增多，PCP患者逐渐增多。现将我院2004年1月至2006年12月收治的AIDS合并PCP患者132例分析如下。     

18F-PET-CT显像在肺癌纵隔淋巴结转移中临床应用价值

目的：探讨PET-CT显像在判断肺癌纵隔淋巴结转移中的临床应用价值。方法：回顾性分析67例肺癌患者在手术前CT、PET、PET-CT显像结果。67例肺癌患者均经手术治疗，手术共取出不同大小淋巴结319枚，其中转移淋巴结68枚，且所有取出淋巴结均经病理证实。以病理结果作为标准，分析CT、PET、PET-CT检查结果的准确性，分别计算CT、PET、PET-CT诊断的准确率、灵敏度、特异性、阳性预测值和阴性预测值等指标，并对CT、PET、PET-CT的诊断准确率进行比较。结果：CT、PET、PET-CT判断肺癌纵隔淋巴结转移的分别为74.6%、80.9%、88.7%；61.8%、80.9%、86.8%；78.1%、79.4%、89.2%；43.3%、53.4%、68.6%；88.3%、93.4%、96.1%。CT诊断纵隔淋巴结的准确率低于PET，差异无统计学意义，PET-CT诊断的准确率高于PET，P＜0.05。结论：PET-CT显像对判断肺癌淋巴结转移的准确率高。     

18F-FDG PET/CT显像在恶性胸膜间皮瘤诊断中的价值

Objective Malignant pleural mesothelioma (MPM) is an uncommon neoplasm arising from mesothelial cells of the pleura. The prognosis is poor with median survival of 4- 12 months. The aim of this study was to evaluate the clinic value of 18F-fluorodeoxyglucose (FDG) PET/CT imaging in the diagno-sis and to staging of MPM and to determine if the mean standardized uptake value (SUVmax) of primary tumor correlates with staging and prognosis. Methods Study was conducted retrospectively including 17 pa-tients with clinical suspicion of MPM from 2002 to 2008. Twelve cases of MPM and 5 cases benign pleural pa-thology were proven by histopathology and clinical follow-up. 18F-FDG PET/CT imaging was performed 1 h af-ter injection of 7.4 MBq/kg 18F-FDG. Patients with MPM confirmed by histopatholagy were divided into two groups: with and without metastasis. PET/CT findings were analyzed to determine if SUVmax of primary tumor correlates with staging and prognosis. Receiver operating characteristic (ROC) curve of SUVmax of primary tumor was evaluated to determine if it was a predictor of metastasis and survival time. Results The difference in SUVmax between MPM and benign pleural were statistical significant (5.78±1.81 vs 2.72± 2.51, t = 2. 8, P < 0.05). The diagnostic sensitivity, specificity and accuracy of 18F-FDG PET/CT imaging for MPM were 100% (12/12) , 4/5 and 94% (16/17). All 7 cases of bone and lymph node metastases were detected by 18F-FDG PET/CT imaging. Area under the curve (AUC) was 0.80. Conclusions 18F-FDG PET/CT imaging is useful in the diagnosis and staging of MPM. High SUVmax in the primary tumor correlates well with prognosis and predication of a greater propensity to have nodal and distant metastasis.     

艾滋病免疫重建炎性综合征与基线CD4^＋T淋巴细胞计数的相关性及治疗分析

目的探讨艾滋病（AIDS）免疫重建炎性综合征（IRIS）与基线CD4^＋T淋巴细胞（简称CD4细胞）计数的相关性及治疗方法。方法将选取的艾滋病病毒（HIV）感染者／艾滋病（AIDS）病人（HIV／AIDS病人）,根据不同基线CD4细胞水平分为两组,观察这两组在高效抗反转录病毒治疗（HAART）后,发生IRIS的情况,以及糖皮质激素在治疗IRIS中的作用。结果共选取HIV／AIDS病人312例,A组157例,CD4细胞计数≤100个／μL：B组155例,CD4淋巴细胞计数〉100个／μL。A组IRIS发生率为40．1％（63／157）,死亡率为6．3％（4／63）;B组IRIS发生率为3．9％（6／155）,无死亡病例;两组IRIS发生率差异有统计学意义（P〈0．01）,死亡率虽有差异,但无统计学意义（P〉0．05）。两组IRIS最常见并发结核病,分别为71．4％（45／63）和33．3％（2／6）。糖皮质激素治疗重症病人症状的有效率为90．2％。结论基线CD4细胞低下是IRIS发生的重要因素,CD4细胞计数≤100个／μL的病人发生IRIS合并结核的较多见,糖皮质激素治疗有效。
