目的　探讨彩超在肾移植术后并发肝脏恶性肿瘤监测中的应用价值。　方法　应用 Acuson12 8XP彩色多普勒超声诊断仪 ,对在我院行异体肾移植手术的终末期尿毒症患者 12 0 0例进行规律随访。　结果　发现 17例恶性肿瘤 ,其中肝癌 7例 ,占 4 1.17%。 5例肿块单发 ,2例多发 ;肿块最大 10 cm× 10 cm,最小 2 .3cm× 2 .1cm。其中 6例手术病理证实 ,1例肝活检证实。　结论　对移植肾术后患者 ,首选彩超随访肝脏变化 ,能早期发现肿瘤 ,为临床选择治疗方案提供时机 ,并提高换肾后发生恶性肿瘤患者的存活率     

介入联合手术治疗门静脉血栓形成7例

目的 评价介入联合手术治疗门静脉血栓形成的疗效。方法 对7例术前确诊为门静脉血栓形成者行开腹经肠系膜上静脉的门静脉内手术取栓、局部溶栓和门静脉狭窄/闭塞段球囊扩张、内支架置入术。2例因小肠坏死、1例因肠腔明显狭窄而同时行部分小肠切除术。结果 7例均治疗成功。术前腹痛、腹胀及消化道症状消失,腹水基本消失。随访3～24个月,平均16个月,均健在,无消化道出血。多普勒超声复查显示门静脉血流通畅。结论 介入联合手术是治疗门静脉血栓形成的安全、有效方法。     

Diabetes mellitus and open heart surgery

A method, based on bedside determinations of blood glucose by nursing staff, was designed to control the administration of insulin to diabetic patients during and following open heart surgery. A computer-controlled intravenous infusion pump was used to deliver the insulin. Excellent control of the hyperglycaemia normally associated with open heart surgery was achieved, with 84 percent of measured blood glucose values falling within 2 mmol/litre of the target value of 6 mmol/litre. The method proved to be simple, effective, and safe.     

大咯血的急诊外科治疗

目的　总结 4 4a急诊手术治疗大咯血经验。方法　回顾性研究 195 8～ 2 0 0 1年在本院急诊手术的 89例大咯血患者 ,收集临床表现、诊断方法、原发病因、治疗和结果等相关资料。结果　 85 4 %病例的X线表现与出血部位一致 ,其它诊断方法 (支气管镜、CT、血管造影术等 )作为重要补充。由于 1982年后的早期外科干预 ,术前咯血总量、咯血平均量和低血压、休克发生比例较前明显减少 ,术后并发症从 1982年前的 2 2 2 %降至 17 1% ,围手术期死亡率从 9 3%降至 0。急诊全肺切除术并发症 ( 2 3 3% )高于肺叶切除术 ( 15 2 % )。在过去 4 4a肺结核一直是大咯血的主要原发病因。结论　符合新的外科治疗标准的患者应及早手术 ;选择切除范围要保守 ,首选叶切     

鹿角状肾结石开放取石的术式选择

目的:探讨鹿角状肾结石开放取石的术式选择、预防术中意外切肾和术后失肾的措施。方法:术中根据结石形态与肾脏解剖关系选择术式。对23例鹿角状肾结石患者行开放取石术治疗,左肾鹿角状结石9例,右肾10例,双肾4例。手术前后加强防治感染,术后充分引流,以预防术后失肾。结果:手术均顺利完成,结石均于术中取尽。术中无一例意外切肾。术后1个月随访全部患者的术侧肾脏功能恢复良好。结论:对鹿角结石,根据结石的形态、分布、肾盂类型、肾积水状态和肾实质厚度等因素综合判断,选择合理的术式,能保障手术安全、干净取石。     

Idiopathic Spinal Cord Herniation as a Treatable Cause of Progressive Brown-Sequard Syndrome

Idiopathic spinal cord herniation is a rare spinal cord disorder caused by spinal cord prolapse through a adural defect. It is a curable disease, so early detection is of particular importance. We report a 38-year-old woman with Brown-Sequard syndrome which was caused by the thoracic spinal cord herniation. Her weakness was almost completely resolved after surgical management, which emphasizes the importance of early diagnosis and surgical management in this rare disease entity.     

Choice of general practice for postgraduate training among medical graduates and undergraduates in Nigeria

A questionnaire survey of career choices was carried out among 112 medical graduates, after one year's internship (group I), during their National Youth Corps programme in Kaduna, Lagos, Cross River and Oyo states of Nigeria, and 365 final-year medical undergraduates (group 2) in the colleges of medicine in the corresponding states. A total of 13% in group I and 40% in group 2 were undecided as regards their first choice. Obstetrics and gynaecology was the most popular first choice in both groups. General practice ranked fifth among group I, but displaced surgery to rank second among group 2. The differences were statistically significant. A total of 41% of group I and 46% of group 2 preferred to work in a teaching hospital, reflecting the high preference for surgical specialties. Twenty-six per cent and 33.7% of respondents in groups 1 and 2 respectively wished to own their own practice or work in the private sector. General practice is a new specialty and its growth is supported by a national postgraduate training programme. A shift towards general practice is seen compared with previous studies of career preference among Nigerian medical graduates and students. This may be due to a changing balance of supply and demand in the medical work-force, or a better assessment of the nation's health problems and manpower needs.
