化疗病人的静脉保护

化疗病人因营养失调 ,骨髓抑制、药物反复刺激、损伤等原因造成血管硬化、塌瘪、脆性大 ,给护理工作带来了一定的难度 ,自 2 0 0 0年始 ,我们摸索出一套保护化疗病人静脉的方法 ,延长了静脉使用的次数和时间。1　临床资料自 2 0 0 0年 1月至 2 0 0 3年 1月 ,我科共收住病人 112 0人食道癌 36 0人 ,乳腺癌 2 6 0人 ,肺癌 30 0人 ,直肠癌 10 8人 ,其他癌 82人 ,其中化疗病人占 6 5 % ,我们均采取了从选择静脉到拔针后处理的方法收到了满意的效果。2　静脉保护2 .1　重视选择静脉　人们根据药物的刺激程度选择不同静脉 ,如强刺激化疗药物如 HN…     

急性白血病男性病人联合化疗后的生育能力和性腺功能

我们测定了７例男性急性白血病（ＡＬ）患者经联合化疗完全缓解（ＣＲ）早期和持续缓解（ＣＣＲ）６月后两个不同阶段的血清ＦＳＨ、ＬＨ、Ｔ和精液参数的变化，以观察ＡＬ患者的性腺功能和生育能力。结果在诱导ＣＲ早期ＦＳＨ明显升高，精液质量明显降低。ＣＣＲ６月后恢复正常。ＬＨ及Ｔ则在两个不同阶段均无明显变化。     

Morphologic changes of the liver following chemotherapy for metastatic breast carcinoma: CT findings

Thirty patients with metastatic breast carcinoma to the liver underwent systemic chemotherapy. Twentyfour of these patients also received hepatic arterial infusion chemotherapy, three in conjunction with hepatic artery embolization. The morphologic changes of the liver believed to be due to chemotoxic effect of treatment occurred in 27 patients, and were evaluated by serial computed tomography (CT) examinations. These included fatty changes in seven patients, severe cirrhotic changes in four, localized atrophy with regional contour changes in three, and areas of low density in the regions of previously treated metastases in 13. The CT features of cirrhosis included density changes along with nodular irregularity of the hepatic borders with marked decrease in liver size and development of ascites.     

Magnetic resonance relaxation times of normal tissue in the course of chemotherapy: a study in patients with bone sarcoma

To study the effect of chemotherapy on normal fat, skeletal muscle, and bone marrow, T1 and T2 relaxation times were measured in 15 patients with bone sarcoma before and after each cycle of preoperative chemotherapy. A section plane containing the tumor and if possible the nonaffected extremity was imaged with combined multiecho spin echo and inversion recovery pulse sequences. T1 and T2 relaxation times were calculated in the normal-appearing tissues. Although some variation was found in the values in the individual patient and between patients, no systematic changes of relaxation times of fat, muscle, or bone marrow occurred in the course of treatment. We conclude that the chemotherapy used in bone sarcoma has no effect on relaxation times of normal fat, muscle, and bone marrow, and that therefore these tissues may serve as a reference for the signal intensity of tumor.     

进展期胃癌术后辅助性化疗的10年随访结果

报告１０２例进展期胃癌术后患者，随机进行３组不同化疗方案并经平均随访１０．７年的结果。所有病例均为１９８３年５月到１９８５年５月间手术者。术后随机给予单一５－ＦＵ、５－ＦＵ＋ＣＣＮＵ和ＭＴＸ＋ＭＭＣ＋５－ＦＵ三组不同化疗。随访至１９９４年１２月止，死亡７７例，存活２５例。结果３、５和１０年总生存率分别为４２．１％；２９．４％和２４．５％。三组间比较，总自下而上率并无显著差异（Ｐ〉０．０５），但中位     

热疗联合化疗与单纯化疗治疗非小细胞肺癌的疗效比较

目的：探讨热疗联合化疗治疗非小细胞肺癌（non—small cell lung carcinoma，NSCLC）的疗效。方法：2003年9月～2006年11月我院对52例NSCLC进行微波热疗联合NP方案化疗联合治疗（热疗联合化疗组），3个周期后评价疗效；并与2006年1～11月16例NSCLC单纯化疗（单纯化疗组）进行对比。结果：热疗联合化疗组近期疗效明显好于单纯化疗组，热疗联合化疗组总有效率（RR）为65．4％（34／52），显著高于单纯化疗组总有效率37．5％（6／16）（Z=-2．419．P=0．016）；热疗联合化疗组结束后疼痛明显改善，单纯化疗组无镇痛作用，差异具有高度统计意义（Z=-6．486，P=0．000）；2组的不良反应主要表现为恶心、粒细胞减少、血小板降低和肝功能异常，差异无显著性（P〉0．05）。结论：热疗联合化疗治疗NSCLC疗效优于单纯化疗治疗NSCLC。     

Renal growth and function 11–28 years after treatment of Wilms' tumour

In order to obtain more information on the long-term effects of treatment of Wilm's tumour we investigated 30 subjects treated at the Children's Hospital between 1960 and 1976. All had been nephrectomized and in 4 the length of the remaining kidney was subnormal. In the other subjects kidney length was related to follow up time and age at follow up. Blood pressure was elevated in 5 subjects. Urinary albumin excretion deviated only slightly from normal. Tubular functions were well preserved in all subjects. In this small series we were unable to establish any relation between the abnormalities observed and the treatment given. Our results suggest that, despite wide interindividual variation those who survive Wilm's tumours seldom have long-term renal complications.     

Chemotherapy in intracerebrally transplanted tumors induced with transplacental administration of ethylnitrosourea in rats

Summary Four tumors of the spinal cord were induced with ethylnitrosourea in rats by transplacental administration and transplanted into the brains of animals of the same strain. One of these intracerebrally grafted tumor lines (G-XIII) was followed up over the first 10 passages and treated with CCNU and other alkylating drugs. The results were compared with findings in an earlier established line (G-XII) in passage 12 and 59, which in the first instance was sensitive to CCNU. The CCNU application prolonged survival in treated animals in various treatment schedules in the first 10 intracerebrally grafted generations of the tumor up to 59%. Induction times of tumors became increasingly shorter. The susceptibility of early passages was similar in both lines. Its loss in late passages went together with diffuse growth of the tumor and reticulin fiber production. In addition, glial fibrillary acid protein expression and formation of intermediate filaments in perivascular tumor cells was lost.     

在体肺隔离高温灌注的实验研究

８条犬于左肺动脉及左房分别插入灌注管及引流管后阻断，使左肺隔离。肝素化预充液中加入超量阿霉素进行常温及高温（４１～４３℃）的灌注转流。监测肺水含量、肺顺应性、血气、肺动脉压、肺实质温度、鼻咽温、血液学等指标，并行病理检查。结果表明：单侧肺隔离高温灌注在手术方法与转流技术上是可行的；它提供的热源简便，温度理想。高温灌注化疗对肺组织有一定影响，但其程度可逆；临床应用是可行的。
