Objective To evaluate the change of blood sugar in diabetic patients after vitrectomy and analyze the relative reasons. Methods Nineteen diabetes II patients (20 eyes) who underwent vitrectomies received the tests of blood sugar preoperatively, and 1～2 hours, 1, 3, and 5 days postoperatively. Analysis of variance, apaired Studentrsquo;s t-test, and correlation analysis were used to analyze the change of postoperative blood sugar and correlation between postoperative blood sugar change and its relative factors. Results Postoperative blood sugar increased significantly compared with the preoperative one (Plt;0.05),reached the peak 1～2 hours postoperatively, and reached almost the preoperative level 5 days postoperatively (Pgt;0.05). There was a positive correlation between blood sugar increase and operation time, preoperative blood sugar level, and diabetic duration (Plt;0.05). Postoperative blood sugar was relative to potentiated anesthesia. Conclusion There is a regularity that blood sugar increases just postoperatively and reaches the preoperative level 5 days postoperatively. The relative factors to blood sugar change include preoperative blood sugar level, diabetic duration, operation time, and potentiated anesthesia. (Chin J Ocul Fundus Dis,2000,16:157-159)
目的 探討乳腺脂肪肉瘤的臨床病理特點及鑒別診斷。 方法 分析2010年3月收治的1例乳腺多形性脂肪肉瘤的臨床表現、組織病理學特征及免疫表型特點，并復習相關文獻。 結果 腫瘤由高級別多形性肉瘤和數量不等的多形性脂肪母細胞組成。免疫組織化學：腫瘤細胞呈S-100蛋白陽性表達、CD34灶性陽性表達，細胞角蛋白、上皮膜抗原、巨噬細胞表面抗原、結蛋白、平滑肌肌動蛋白、肌調節蛋白、肌漿蛋白、CD31均呈陰性表達。結論 乳腺脂肪肉瘤是一種少見的原發于乳腺的間葉源性腫瘤，診斷上應首先排除乳腺化生性癌和惡性葉狀腫瘤伴脂肪肉瘤分化，應依據形態學特點和免疫組織化學結果進行鑒別。
