Panhypopituitarism as first manifestation of a lung cancer

Pituitary metastases of solid tumours are infrequent, specially as a first manifestation. When they happen, they are usually due to breast or lung cancer and are asymptomatic or produce diabetes insipidus. It is very strange that they produce hormonal deficiency. We present a case report of a bronchogenic adenocarcinoma in a 65-year-old man which began with panhypopituitarism, diabetes insipidus and visual alterations. Magnetic resonance imaging revealed a large sellar mass, with clivus infiltration and invading the right cavernous sinus. The biopsy result was adenocarcinoma metastases from lung cancer.     

中老年晚期非小细胞肺癌射频损毁治疗与化疗的临床比较

目的:探讨射频损毁治疗晚期非小细胞肺癌的疗效及应用价值。方法:自1999年12月至2000年8月收治73例晚期中老年非小细胞肺癌患者,分别给予射频损毁治疗和以铂类为主的联合化疗;观察比较其近期疗效、中位生存期、1年及2年生存率;并分析其治疗后生存质量。结果:射频损毁治疗组有效率(CR+PR)为71.5％(30/42),明显高于化疗组的43.3％,差异呈显著性,(x2=4.63,P<0.05)。射频损毁治疗组中位生存期、1年及2年生存率及治疗后生存质量均高于化疗组。结论:射频损毁治疗对晚期非小细胞肺癌治疗,具有较好的中期疗效,且能明显提高生存质量。     

Quantitative observation by enzyme cytochemistry of human rectal adenocarcinoma cells killed by LAK cells

Activity of succinic dehydrogenase(SDH)and acid phosphatase(AcPase)of effector-target cells during the process of LAK cells killing HR8348 cells was estimated by enzyme cyto-chemistry technique.SHD positive granules and AePase gray level were assayed with MIAS-300image analyser.The results showed:(1)After cocultivation of effector and target cells for vari-ous times,the activity of AcPase of HR8348 cells was apparently higher than that of the controlgroup,and it increased following prolonged coincubation.SDH activity of target cells increasedmarkedly within 30 and 60 rain cocultivation,but became low after 90 min treatment.(2)Ac-Pase content within LAK cells at 60,90,120,180 and 240 rain cocultivation was significantlyhigher than that of control group(P<0.01).The phenomenon of high AcPase and SDH activitywithin effector-target cells indicates that the function of the two types of cells was in an activestate.At the early stage of effector-target combining,the increase of SDH with HR8348 cellsmay be related to defensive function of the target cells.Higher AcPase activity of target cells in-dicates the activation of lysosomal enzyme which serves as the material basis for autolysis of thecells.     

Lung cancer in Israel, 1962–1982 I. Jews and Arabs

The magnitude and dynamics of lung cancer incidence in Jews and Arabs in Israel between the years 1962 and 1982 were studied. In general, age-standardized incidence rates increased consistently between the years 1962 and 1976 among Jewish (24% increase) and Arab (39%) males, and to a lesser degree among Jewish females (15%). Arab females had the highest (77%) increase. From 1977 to 1982 a general decrease in incidence rates, which was largest among Arab males (19%) and females (15%), was noted. Rates among Jewish males are currently 26% higher than among Arab males, and are 162% higher among Jewish females than in Arab females. Lung cancer rates in both males and females in Istrael (Jews and Arabs) are lower than in most developed countries in the world. Among the possible reasons are differences in the population risk factors profile, availability of health care and the level of diagnosis and ascertainment of cases.     

肺癌放疗前后MRI价值研究

１９９４年１０月以来，作者有计划地对条件允许的肺癌病人，于放疗开始前１日和放疗结束后３日分别行胸部ＭＲＩ检查。通过分析我们认为ＭＲ１在肺癌病人放疗前后以下方面评价中具有较大价值：１．原发肿瘤特征；２．肺门纵隔肿大淋巴结；３．原发肿瘤和肿大淋巴结与大血管关系的鉴别；４．肿块与肺不张鉴别；５．胸壁侵犯范围；６．放谢性肺纤维化与肿瘤残留或复发鉴别。     

肺癌患者红细胞免疫功能和T淋巴细胞亚群的检测及临床意义

作者对62例肺癌患者进行红细胞免疫功能及T淋巴细胞亚群测定，并与20例正常人对照。结果显示：肺癌组红细胞膜C3b受体活性（RBC－C3bRR）、CD3 、CD4 、CD4 ／CD8 比值均低于正常人（P＜0．05～0．01），红细胞膜的吸附免疫复合物（RBC－ICR）、CD8 均高于正常人（P＜0．05～0．01），因此认为红细胞免疫及T淋巴细胞亚群测定对肺癌的诊断、治疗及病情预后估计有一定价值。     

胸部螺旋CT扫描技术及临床应用

作者采用了不同的人体体模和临床应用实验，对常规和螺旋ＣＴ扫描进行了比较研究。结果显示：与常规ＣＴ比较，螺旋ＣＴ图像无失真，变形。分辨率略差于常规ＣＴ。改变扫描条件和床速，图像质量无明显改变。改变扫描图像数学处理模式后，分辨率有所增加，但螺旋扫描仍冰及常规扫描。在临床应用上，螺旋扫描有许多优点。如何采用一次屏气技术，对病人某一脏器检查只需一次连续扫描。扫描速度快，不易产生运动伪影，所选脏器的扫描无盲     

系统性红斑狼疮的肺胸膜损害
