肾移植患者血脂,脂蛋白和载脂蛋白变化及其临床意义

观察了４６例肾移植患者血浆脂质代谢的改变，结果显示，肾移植患者血总胆固醇（ＴＣ）、甘油三酯（ＴＧ）、极低密度脂蛋白胆固醇（ＶＬＤＬ－Ｃ）和载脂蛋白（ａｐｏ）Ｂ１００明显升高，而ａｐｏＡＩ、ａｐｏＡＩａｐｏＣⅡ／ａｐｏＣⅢ明显降低，同时还观察到，有心脑血管合并症的病者血ＴＣ、ＴＧ、ＴＣ／ＨＤＬ－ｃ、ａｐｏＢ１００升高ａｐｏＡＩ降低比合并症的病者更显著。上述结果表明肾移植后脂质代谢有明显改变，且存在加     

Influence of differences in tumor vascularity upon the effects of hyperthermia

Summary Utilizing two types of human renal carcinoma heterotransplanted in nude mice, we investigated the variations in hyperthermic effects (42.5°C for 30 min) caused by differences in tumor type with special reference to variations in tumor vascularity. In the hypovascular JRC1 strain, sporadic vascular dilation was observed throughout the tumors after heating. Destruction of tumor cells was observed mainly in the region of dilation. In the hypervascular JRC11 strain, homogenous vascular dilation was observed immediately after heating, mainly at the periphery of tumors. There was a decrease in the viability of cells in the center of the tumor. Therefore, the hypervascular tumors showed greater destruction mainly at the center where blood circulation was reduced. The range of necrosis was also greatly affected by the extent of vascular dilation caused by heating in hypovascular tumors.     

Regression of Pulmonary and Multiple Skeletal Metastases from Renal Cell Carcinoma by Nephrectomy and Alpha-interferon Therapy: A Case Report

We report a rare case of advanced renal cell carcinoma in apatient who showed complete resolution of metastases to thelung and bones after nephrectomy, partial jejunectomy and subsequentalpha-interferon therapy. The patient was a 54-year-old manwhose right lung and left femur metastases were detected beforenephrectomy. In the seventh week after nephrectomy, a partialjejunectomy was carried out because of the obstructive ileuscaused by intraluminal multiple metastases of the jejunum. Apathological fracture of the metastasized right humerus occurredsubsequently. After four months of intramuscular alpha-interferonadministration (3x106 units/day), however, x-rays revealed thecomplete disappearance of the metastatic lung shadow and a solidunion of the humerus, and there were no tumor cells in the femurspecimen resected at the subsequent reconstruction surgery ofthe left leg. Seven years have passed from onset, and the patientis still alive and disease free.     

肾综合征出血热地鼠肾细胞Ⅱ型灭活疫苗的安全性、免疫性及其流行病学效果考核

目的：考核HFRS地鼠肾细胞Ⅱ型灭活疫苗的安全性、免疫法及其流行病学效果。方法：采用间接免疫荧光抗体试验（IFA）、微量细胞变性中和试验（MCPENT），检测接种者血中荧光抗体及中和抗体水平；调查接种组与对照组发病情况。结果：以怀宁、广德两县18个村为疫苗观察现场，接种组7499人，对照组7261人，中强反应率为224％（5／223）。3针全程免疫后中和抗体阳转率为63．33％（19／30），荧光抗体阳转率为38.58％（27／70）；接种后1年内接种组无发病，对照组发病3例。结论：该疫苗的安全性较好；有一定水平的免疫应答，但防病效果应进一步观察确证。     

继发性甲旁亢的锁骨骨吸收

１８例慢性肾衰继发性甲旁亢病人发现有锁骨骨吸收。发病部位包括锁骨内端、外端、外１／３下缘及内段下缘４个部位。其中锁骨内、外端骨吸收属软骨下骨吸收，内、外段下缘骨吸收属韧带下骨吸收。作者对锁骨骨吸收的Ｘ线表现及发病机制作了讨论。认为锁骨骨吸收是继发性甲旁亢的重要Ｘ线征象，对诊断肾性骨病具有重要的意义。     

Multiple Cerebral Haematomata and Peripheral Nerve Palsies Associated with a Case of Juvenile Diabetic Ketoacidosis

A 15-year-old girl presented de novo in diabetic ketoacidosis having been comatose for 24 h (day 1). A CT scan and lumbar puncture performed on admission were normal and her conscious level slowly improved over several days. On day 7 she had central neurological signs of bilateral knee clonus and an extensor plantar response. In addition, she had developed lower motor neurological signs of an ulnar nerve palsy of the left forearm, and ulnar, median, and radial nerve palsies of the right forearm. Magnetic resonance imaging (MRI), performed on day 12, showed multiple small cerebral haematomata with appearances at least several days of age. The scattered lesions were localized particularly to the parieto-occipital region, with sparing of the basal ganglia and without cerebral oedema, a novel feature not previously described in juvenile ketoacidosis. Four months later there was minimal residual disability of her right arm. The clinical findings together with the MRI images suggested that the peripheral nerve and central lesions were temporally related, suggesting a common aetiology. However, it is likely that MRI showed cerebral lesions which may have been missed by the conventional CT scanning performed initially.     

Is cytomegalovirus a cause of ureteral stricture in renal transplant recipients?

Cytomegalovirus (CMV) is regarded as a predominant infectious agent in solid organ transplants. CMV disease has highly protean clinical manifestations. Nevertheless, urinary tract involvement seems to be very rare during CMV infection. We report two cases of renal transplant recipients in whom ureteral stricture developed in the course of CMV disease. Histologic data were available for them and were consistent with CMV infection. We discuss previous case reports and propose physiopathologic mechanisms. Received: 3 October 1996 Received after revision: 13 February 1997 Accepted: 17 February 1997     

Liver transplantation for fulminant hepatic failure: importance of renal failure

Abstract One hundred eighty-one consecutive patients with fulminant hepatic failure (FHF) presenting in a 2-year period were reviewed. In this cohort we examined the impact of pretransplant renal failure on mortality and morbidity following orthotopic liver transplantation (OLTx). Twenty-seven patients (18 female, 9 male) with a median age of 43.5 years (range 19–65 years) underwent OLTx. FHF was due to idiosyncratic drug reaction ( n = 4), paracetamol overdose ( n = 3), seronegative hepatitis ( n = 17), hepatitis B ( n = 1), veno-occlusive disease ( n = 1), and Wilson's disease ( n = 1). Renal failure was present in 14 patients, 7 of whom died (whereas there was 100 % survival in patients without renal failure). Pretransplant renal failure was associated with prolonged mechanical ventilation (13 days vs 6 days, P = 0.05), prolonged intensive care stay (17 days vs 8 days, P - 0.01) and prolonged hospital stay (27 vs 21 days, P = NS). Pretransplant renal failure did not predict renal dysfunction at 1 year after OLTx. We conclude that the survival of patients transplanted for FHF is inferior to that of patients transplanted for chronic liver disease (67 % vs 88 % 1-year survival in Birmingham). For patients with FHF undergoing transplantation, pretransplant renal failure strongly predicts poor outcome with significantly greater consumption of resources.     

小儿肾脏疾病血,尿内皮素的变化

目的研究小儿肾脏疾病血、尿内皮素（ＰＥＴ、ＵＥＴ）的水平及其相互关系。方法采用同位素放免方法检测了肾病综合征（ＮＳ），肾小球肾炎（ＧＮ），肾功能衰竭（ＲＦ）共７２例患儿血及尿中ＥＴ，血心钠素（ＡＮＰ）水平。结果ＮＳ，ＧＮ，ＲＦ三组的ＰＥＴ及ＵＥＴ值明显高于对照组，尤其ＲＦ组（Ｐ＜００５，Ｐ＜０．０１）。ＡＮＰ值在ＧＮ组和ＲＦ组明显高于对照组（Ｐ＜００１）。８例ＡＲＦ患儿恢复期血ＥＴ水平下降，６例ＣＲＦ患儿虽经治疗，但血ＥＴ水平不降或上升。结论ＥＴ在小儿肾脏疾病发病机理及病情进展中可能起重要作用，其值高低与病情严重程度及预后有关。
