自体胸腔积液上清作为培养液对肿瘤浸润淋巴细胞生长的影响

目的：观察自体胸腔积液上清作为培养液对肿瘤浸润淋巴细胞(TIL)生长的影响．方法：恶性胸腔积液中的TIL经贴壁法分离后，分别采用含有细胞因子白细胞介素-2(IL-2)、CD3单克隆抗体(OKT3)及植物血球凝集素(PHA)的自体胸腔积液上清及含10％人AB型血清的RPMIl640进行培养，比较两种培养液对TIL的增殖速度、培养前后免疫表型变化和对自体肿瘤细胞的杀伤活性。结果：培养2周，经统计学比较发现，自体胸腔积液上清作为培养液对TIL的生长速度、免疫表型和对自体肿瘤细胞杀伤活性的影响与应用含10％人AB型血清的RPMIl640培养液培养无差异。结论：自体胸腔积液上清作为培养液培养TIL是可行的。为自体TIL疗法治疗恶性胸腔积液提供理论基础。     

Malignant pelvic paraganglioma: A case report

Pheochromocytomas arising from outside the adrenal glands are called paragangliomas and constitute a rare disease and can occur in the pelvic retroperitoneum. Symptoms of excess catecholamine production, as well as elevated urine vanillylmandelic acid levels and serum and urine norepinephrine levels, are highly diagnostic for paraganglioma. Imaging can be helpful for the diagnostic of these pelvic tumors, differentiating them from other pelvic masses. We hereby present a case of pelvic malignant paraganglioma.     

结核病的体液免疫诊断研究(V.PPA—ELISA检测胸、腹水结核抗体)

以PPD为抗原,建立了检测人体胸、腹水中抗结核菌抗体的PPA-ELISA,对方法的特异性、重复性和最适检测条件进行了探讨。63份患者胸、腹水标本的检测结果显示,28例结核性胸膜炎(腹膜炎)患者胸、腹水的特异性抗体水平非常明显地高于35例对照组患者(P<0.001)。本法简便快速且灵敏,可作为结核性胸膜炎(腹膜炎)的辅助诊断方法;其动态观察还可为疗效考核提供依据,作者等建议加以推广应用。     

复方苦参腔内灌注治疗对恶性胸腔积液患者胸水中VEGF、MMP含量的影响

目的探讨复方苦参腔内灌注治疗对恶性胸腔积液患者胸水中VEGF、MMP含量的影响。方法选择在本院接受住院治疗的恶性胸腔积液患者作为研究对象,随机分为接受常规胸腔内化疗的对照组及接受复方苦参腔内灌注治疗的观察组,比较两组患者的治疗后胸水VEGF、MMP含量及T细胞亚群分布差异。结果 (1)观察组患者接受治疗后的VEGFA、VEGFB、VEGFC水平均显著低于对照组患者(P<0.05);(2)观察组患者接受治疗后的胸水MMP-2及MMP-9含量均显著低于对照组患者(P<0.05);(3)观察组患者接受治疗后的CD3+、CD4+、CD4+/CD8+水平均明显高于对照组患者(P<0.05)。结论复方苦参腔内灌注治疗可以明显降低患者胸水VEGF、MMP含量,优化机体免疫功能。     

高频彩超对小体积恶性乳腺叶状肿瘤的诊断价值

目的探讨高频彩超对小体积恶性乳腺叶状肿瘤的诊断价值,提高小体积恶性PTB的术前诊断率。方法回顾分析4例经手术病理确诊的小体积恶性乳腺叶状肿瘤的声像图表现,并与该研究在同一台机器同一探头操作、预设条件一样前提下,病灶大小接近的,患者年龄相仿的,病灶深度差不多的6例纤维腺瘤的声像图进行对比分析。结果肿块最小者2.1cm×1.8 cm,最大者4.6 cm×3.7 cm;小体积恶性乳腺叶状肿瘤的CDFI表现：血供较丰富,Ⅱ级1例,Ⅲ级3例。纤维腺瘤的CDFI表现：血供较稀疏,0级1例,Ⅰ级4例,Ⅱ级1例。结论小体积恶性乳腺叶状肿瘤的CDFI表现具有较高的特异性,容易分辨,对于诊断小体积恶性乳腺叶状肿瘤有较高的实用价值。     

Eroded Valves,Recurrent Pleural Effusions,and Ultimately Heart–Liver Transplant

A patient with eroded tricuspid and pulmonic valves, who eventually developed elevated right atrial and systemic venous pressure that led to hepatic cirrhosis and recurrent pleural effusion, is presented. The complex issues involved over a long period in this patient, who ultimately required combined heart and liver transplant, are discussed.     

老年妇女绝经后阴道流血的原因分析与治疗对策探讨

目的探讨分析老年妇女绝经后阴道流血的原因及治疗方案。方法回顾分析2007年1月-2011年12月我院接收的211例绝经后阴道流血及血性白带为主要症状的女性患者,排除因妊娠引起流血的病例,对其余患者进行妇科检查、经阴或腹部B超检查、TCT检查及宫腔镜下病理活检。观察分析所有患者的阴道流血的病因及病变程度。结果依据本组患者的各项检查及病理报告可分为：生殖器官炎症125例,子宫肌瘤18例,恶性肿瘤53例,其他15例。结论绝经早期阴道流血多数患者由生殖器官良性病变引起的,但随着绝经时间的延长,恶性程度越高,针对病因选取恰当的治疗方式才是行之有效的方案。     

Aseptic knee effusion associated with calcified guinea worms

Reported is a case of aseptic knee effusion associated with the presence of a calcified guinea worm, Dracunculus medinensis, in close proximity to the joint. The patient, a native of Nigeria, presented with chronic right knee pain and swelling. He did well with symptomatic treatment including non-steroidal antiinflammatory drugs, rest, ice, and elevation of the leg. Dracunculiasis is prevalent in parts of Asia and Africa, but has been described only rarely in the United States.     

Serum sialic acid in malignant tumors,bacterial infections,and chronic liver diseases

Summary The total serum sialic acid concentration was determined in 2,264 persons with various malignant tumors, bacterial infections, rheumatic diseases, and chronic liver diseases, and in a control group. The thiobarbiturate method according to Warren was used [34].The upper limit (95% percentile) in the control group was 2.23 mol/ml. Higher values were found in the groups with neoplasms (mean: 3.04 mol/ml), inflammatory diseases (e.g., pneumonia: 3.02 mol/ml), and active rheumatoid arthritis (3.05 mol/ml). In the group with malignant diseases, the sialic acid concentration at the time of diagnosis was highest for bronchial carcinoma (3.29 mol/ml) and lowest for breast cancer (2.58 mol/ml). In chronic liver diseases the mean sialic acid level was lower than in a heterogeneous group of noninflammatory and nonneoplastic diseases.The estimation of the serum sialic acid concentration could be useful in the detection of tumor burden and metastases, and in the evaluation of the later course and prognosis of malignant neoplasms if bacterial/inflammatory and active rheumatoid processes can be excluded.     

Imaging features of maxillary osteoblastoma and its malignant transformation

We report two cases of osteoblastoma, one of them an unusual case in a 32-year-old woman in whom a maxillary tumor was confidently diagnosed as an osteoblastoma at the time of primary excision and subsequently transformed into an osteosarcoma 7 years after the onset of clinical symptoms. The other patient developed osteosarcoma arising in the maxilla, which was diagnosed 3 years after the primary excision and is very suggestive of malignant transformation in osteoblastoma. We present the radiological features, including computed tomographic and magnetic resonance imaging studies, of this unusual event of transformed tumor and compare imaging features of benign and dedifferentiated counterparts of this rare tumor complex.Members of the Group for the Image Diagnosis of Craniofacial Disorders
