A randomized trial comparing double-drug and triple-drug therapy in primary cadaveric renal transplants

A controlled trial was carried out in 209 primary cadaveric renal transplants to compare the effects of cyclosporine and steroids (double therapy) with those of cyclosporine in lower initial dose, azathioprine, and steroids (triple therapy). Patients have been followed 1-36 months since transplantation. Actuarial two-year graft survival (double 74%, triple 76%) and two-year patient survival (double 90%, triple 93%) were similar for both groups. Further analysis of particular risk factors including age, diabetes, HLA matching, acute renal failure, and use of sequential Minnesota antilymphocyte globulin in patients with delayed graft function also showed similar outcomes with both immunosuppressive regimens. Initial hospitalization time, rate of rejection, incidence of serious infection, and rate of rehospitalization were not different. Mean CsA doses and mean trough whole-blood levels were higher in double-therapy patients at hospital discharge but not by three months posttransplant. There were no differences between the two groups in iothalamate clearance at any time. Hypertension was more frequent six months posttransplant in the triple-therapy group (p less than 0.05). Thus, similar results were obtained with both regimens, and except for hypertension no regimen appeared to have increased side effects up to three years posttransplant.     

颞颌关节继发性滑膜炎的临床诊断

颞颌关节滑膜炎分为原发性和继发性两种，颞颌关节紊乱综合症的滑膜炎为继发性滑膜炎。本文通过对１０６例颞颌关节紊乱综合症患者的临床检查、关节许氏位以及关节上腔造影的Ｘ线检查，同时对４２例进行了关节内窥镜检查，在此基础上探讨了继发性滑膜炎的临床诊断标准．作者认为急性滑膜炎主要是以关节疼痛和滑膜血管的改变为主，慢性滑膜炎的临床症状与滑膜组织改变以及关节骨组织的改变均有关系。     

Renal artery embolization with ethanol and gelfoam for the treatment of ureteric fistulae with one year follow-up.

Two patients with ureteric fistulae who were unfit for reconstructive surgery were treated by renal ablation using intra-arterial ethanol, gelfoam fragments and in one case coils. In both cases the fistulae dried-up on the same day and both patients are well and normotensive a year later. Our conclusion is that renal ablation by arterial embolization with ethanol can be a valuable alternative to surgery to treat ureteric fistulae in patients who are poor surgical risks.     

低剂量甲基汞在小鼠体内分布及其对细胞周期进程的影响

连续９０天饮用含甲基汞浓度为１／１０００ＬＤ５０、１／１００ＬＤ５０、１／５０ＬＤ５０和１／１０ＬＤ５０的自来水的雄性昆明小鼠，各脏器中总汞含量均高于对照组（Ｐ＜０．０５～０．００５），并且随着染毒剂量增加，脏器中总汞含量也随之增高。同时采用ＦＡＣＳｃａｎ流式细胞仪和“ＣｅｌｌＦＩＴ”软件分析脾细胞周期进程，发现除１／１０００ＬＤ５０剂量组外，其余各剂量组从Ｇｏ／Ｇ１时相进入Ｓ时相的脾细胞百分数均明显高于对照组（Ｐ＜０．０５），与染毒剂量呈明显正相关。表明连续经口摄入低剂量甲基汞小鼠脾细胞周期进程加快，细胞ＤＮＡ复制增强。     

Acute management of intracranial hemorrhage in patients receiving thrombolytic therapy: case reports

Intracranial hemorrhage is an uncommon complication of antithrombotic therapy. We present two patients who suffered life-threatening intracranial bleeding as a complication of thrombolytic/anticoagulant treatment. Early diagnosis and treatment appear to be crucial factors for survival. We suggest an approach to perioperative management for intracranial hemorrhage resulting from antithrombotic therapy.     

Four cases of lung cancer associated with idiopathic interstitial pneumonia

It is well known that lung cancer develops frequently in patients with idiopathic interstitial pneumonia (IIP) (9.8-22.8%). We investigated 4 patients who developed lung cancer among the 28 patients with IIP (14.3%) who were admitted to our hospital from June 1981 to March 1989. Many reports have pointed out the clinical features of lung cancer associated with IIP as male sex, old age, heavy smoking, and poor prognosis. Our 4 series were agreed with these clinical features. Lung cancer associated with IIP have been often reported to occur in the lower and peripheral regions of the lung, and honeycomb structures are frequently seen. But we found that lung cancer in IIP could actually occur in both the lower and upper regions of the lung and does not occur only in the honeycomb structures. There was no obvious dominance of any histological type among the tumors. If lung cancer is suspected in a patient with IIP, tumor markers are of some value for diagnosis, but are not sensitive enough to be used alone.     

小鼠卵细胞质内显微注入单精子受精的实验研究

为了探讨提高小鼠卵细胞质内单精子注入受精率的方法，选取鼠龄１２－１４周的健康昆明白小鼠作为精子和卵子的供体，受用ＩＣＳＩ技术，以受精后二细胞卵裂的形成率为指标，了解不同采卵时间，不同微注射针参数及不同培养液对细胞质单精子注入的影响。结果表明，ｈＣＧ注射后１８－１９ｈ采卵，用针尖内径为４－５μｍ，斜面角度为３５－４０度的微注射针进行ＩＣＳＩ操作受精后卵子置ＣＺＢ中培养可获得较多的２细胞胚，卵裂率明显     

Traumatic esophageal rupture: unusual cause of acute mediastinal widening

We have presented the case of a 32-year-old man who sustained blunt trauma to the chest in a motor vehicle accident. Plain roentgenograms showed a widened mediastinum and pneumomediastinum, and an esophagogram with water-soluble contrast material showed an esophageal laceration at the T-4 level.
