皮瓣展平法在耳廓再造时扩张皮瓣感染中的应用

目的探索耳廓再造时扩张皮瓣感染的处理方法。方法分析中国协和医科大学整形外科医院外耳冉造中心2003年1月～2005年12月耳廓再造时耳后扩张皮瓣发生感染，经皮瓣展平法处理，感染控制后进行耳再造的12例（12耳）患者的治疗情况。结果12例（12耳）患者手术顺利，术后恢复好，再造耳效果与无感染者无明显差异。结论皮瓣展平法是耳廓再造时扩张皮瓣感染较理想的处理方法。     

Revascularized fibula for tibia replacement in adamantinoma

Adamantinoma of long bones is one of the rarest of malignant bone tumors; it is commonly located in the middle or lower third of the diaphysis of the tibia. A case with multiple occurrences affecting both the tibia and fibula is presented. En bloc resection with wide operative margins was performed, and a large tibial defect of 23 cm was effectively bridged by a revascularized free fibular flap. At 13 months follow-up, there was no sign of local recurrence or metastasis, and the patient was mobile.     

Lugol液染色对食管早期癌和癌前病变的诊断价值

目的 探讨Lugol液染色对食管早期癌和癌前病变的诊断价值。方法 对45例食管黏膜可疑病变经内镜以2％Lugol液喷洒染色，观察黏膜染色情况，并取活检送病理组织学检查。结果 45例食管病变染色后，39例呈浅染色或不染色，其中食管癌8例（食管早期癌5例，进展期癌3例），Barrett食管5例，轻至中度不典型增生1l例。本组Lugol液染色对食管早期癌和癌前病变的检出率达46．7％。结论 内镜下应用Lugol液染色结合活检有助于食管早期癌和癌前病变的诊断，且操作简便，具有重要的临床价值。

Prostaglandin el attenuates impairment of cellular immunity after cardiopulmonary bypass

OBJECTIVE: It is well documented that cardiopulmonary bypass (CPB) severely impairs cellular immunity. The objective of this study was to investigate the effect of prostaglandin E1 (PGE1) on cellular immunity after CPB. METHODS: Patients who underwent elective cardiac surgery were randomly divided into the PGE1 group (n=12) and the control group (n=12). In the PGE1 group, PGE1 was administered at 20 ng/kg/min from just after the induction of anesthesia to the end of surgery. Peripheral blood mononuclear cells (PBMCs) were taken before anesthesia and on postoperative days 1, 3 and 7 (POD 1, POD 3 and POD 7). Proliferation responses of T cells to phytohemagglutinin (PHA) and pure protein derivative (PPD) antigen were measured as indicators of cellular immunity. RESULTS: PGE1 significantly attenuated the impairment of both PHA and PPD response after cardiac surgery on POD 1 (PHA response, 30 +/- 21% vs. 53 +/- 32%, control vs. PGE, p=0.048; PPD response, 18 +/- 21% vs. 39 +/- 27%, control vs. PGE, p=0.046). The reduced glutathione content of PBMCs in the control group was significantly decreased on POD 1. CONCLUSION: PGE1 attenuated the impairment of cellular immunity after cardiac surgery with CPB by reducing oxidative stress on PBMCs.
