THE TREATMENT OF SPINAL CORD INJURY CASES BY MEANS OF SPINAL OMENTUM TRANSPOSITION

Omentum transposition to cervical spinal cord for the treatment of traumatic cervical spinal cord myelopathy.In treating spinal cord injury, the clinic of cervical spinal cord injury has to face the problems of tetraplegia and control of Respiration. The application of various kins of treatment include skull traction, laminectomy, intervebral bone graft fusion and omen turn spinal cord transposition. We have treated 10 cases in the period from June, 1986 to June, 1983. The discussion will focus on the Oinentum transposition to cervical spinal cord and the related problems of cervical spinal cord injury.     

Differential Effect of Diarrhea on FK506 Versus Cyclosporine A Trough Levels and Resultant Prevention of Allograft Rejection in Renal Transplant Recipients

Diarrhea is the most frequently reported adverse event in patients treated with mycophenolate mofetil. Twenty-six renal transplant patients on a mycophenolate mofetil-based immunosuppressive regime with persistent afebrile diarrhea were examined. Diarrhea caused a significant rise in FK-506 trough levels despite intake of stable doses, necessitating FK-506 dose reductions of 30% to obtain pre-diarrhea trough levels. In contrast, trough levels of cyclosporine A remained stable without dose adjustments. This suggests that absorption and/or metabolism is differentially altered for FK506 compared with cyclosporine A in patients with diarrhea. In nine patients mycophenolate mofetil was reduced or stopped because of persistent diarrhea without identifiable cause. This resulted in end-stage renal disease because of chronic rejection in two patients, and in acute rejection in two patients, all taking FK506 and steroids. Therefore, dose adjustments of FK506 in patients with diarrhea must be carefully monitored, especially when doses of mycophenolate mofetil are also reduced.     

几种杀虫剂对印鼠客蚤的毒力测定

本文报告用罐头瓶药膜法和点滴法对实验室饲养的3日龄未吸血印鼠客蚤为试验对象,测试了溴氰菊酯、滴滴畏、久效磷、磷胺、喹硫磷、倍硫磷半数致死量(LD_(50))和半数致死浓度(LC_(50))。结果以溴氰菊酯和喹硫磷的LC_(50)值较低,磷胺和滴滴畏的数值较高,LD_(50)以溴氰菊酯和倍硫磷毒力较强,磷胺和久效磷次之,雌雄个体差异不明显。     

1例乙型慢性重型病毒性肝炎合并真菌性肺炎的治疗护理

两性霉素B毒性大，不良反应多见，但它又是治疗危重深部真菌感染的有效药物。该药对严重肝病病人禁用，2004年我病区收治了1例病毒性肝炎乙型慢性重型（早期）合并真菌性肺炎的病人。医生在权衡利弊慎重考虑后作出对该病人使用两性霉素B的决定。现报告该病人使用两性霉素B的治疗与护理情况。     

MITOCHONDRIAL MYOPATHY AND MITOCHONDRIAL ENCEPHALOMYOPATHY

This paper is the first report of mitochondrial encephalomyopathy and mitochondrial myopathy diagnosed in China. It includes l case of mitochondrial encephalomyopathy with lactic acidemia and stroke-Iike episodes (MELAS), 5 cases of mitochondrial myopathy with skeletal muscles predominantly involved, and 2 cases of mitochondrial myopathy with external ocular muscles predominantly involved. The diagnosis was confirmed by muscle biopsies which revealed the "ragged-red-fiber" CRRF) in modified Gomori trichrome CMGT) stain, accumulation of lipie droplets in oil-red-O stain in frozen sections, and aggregates of abnormal mitochondria with complex paracrystalline inclusions and distorted cristae and osmiophilic dense bodies in their matrix in electron microscopy.     

消化道肿瘤免疫相关不良事件的临床分析

目的探讨消化系统恶性肿瘤中免疫检查点抑制剂(immune checkpoint inhibitors, ICIs）导致免疫相关不良事件(immune-related adverse events, irAEs)的特征及危险因素。方法 回顾性分析2019年4月至2021年10月北京大学肿瘤医院诊治的95例接受ICIs治疗的消化系统恶性肿瘤患者的临床资料和irAEs发生情况。irAEs、内分泌irAEs危险因素分析采用二元Logistic回归分析。结果 95例患者共应用ICIs治疗458例次,中位应用3例次(范围：1~33例次）。irAEs的发生率为55.8%,3~4级irAEs发生率为9.5%。最常见的irAEs为皮肤irAEs(27.4%）和内分泌irAEs(22.1%）。内分泌irAEs中甲状腺功能减退最常见(16.8%）,肾上腺皮质功能减退(2.1%）和垂体炎(1.1%）少见。多数irAEs发生于免疫治疗初期,78.2%发生于12周内。过敏反应、皮肤irAEs最早发生,中位发生时间分别为2周(范围：0.9～3.1周）和3.8周(范围：0.9～17.9周）,内分泌irAEs中位发生时间为6.9周(范围：3.0～52.1周）。多因素分析显示,女性(OR=5.197, 95%CI：1.166～23.154, P=0.031)和微卫星高度不稳定(microsatellite instability-high,MSI-H） (OR=35.048, 95%CI：2.756～445.787, P=0.006)是内分泌irAEs发生风险增加的独立危险因素,免疫治疗联合化学药物治疗(OR=0.107, 95%CI：0.021～0.412, P=0.001）是内分泌irAEs的独立保护性因素。结论在消化系统恶性肿瘤中应用ICIs具有较好的安全性。女性和MSI-H患者出现内分泌irAEs风险增加,联合化学药物治疗可能降低内分泌irAEs发生风险。
