腮腺混合瘤功能性切除与以往术式的比较

目的探讨腮腺混合瘤功能性切除术的应用价值。方法选择位于腮腺的多形性腺瘤25例，在瘤体包膜外0．5—1．0cm正常腮腺组织内，切除瘤体及腺体；对照组25例采用经典方式进行治疗。比较术后并发症、复发率、面部畸形及残留腺体的功能。结果观察组较对照组并发症少，术后畸形小，残留腺体有功能，随访1～5年无复发。结论腮腺多形性腺瘤功能性切除较经典手术更有优越性。     

奥曲肽治疗消化系内分泌肿瘤的研究进展

奥曲肽（Octreotide）是一种长效生长抑素（Somatostatin．SS）的类似物，商品名善得定（Sandostatin）。其分子结构为一环形肽，具有活性的四个氨基酸排列顺序与ss相同，故可与广泛存在于中枢神经系统、垂体和胰腺β细胞等处的sS受体结合产生生物学效应。目前奥曲肽主要应用于消化道疾病和多种内分泌肿瘤的治疗。     

广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.

听神经瘤的MRI表现

听神经瘤是桥小脑角区肿瘤中最常见的一种，有时影像学表现与三叉神经瘤、脑膜瘤、胆脂瘤等相似，易误诊。今收集近年来经手术病理证实的18例MRI和临床资料完整的听神经瘤病例，与病理学结果对照分析如下。     

经乙状窦后入路显微手术治疗继发性三叉神经痛37例

目的探讨经乙状窦后入路显微手术治疗桥小脑角占位性病变引起的继发性三叉神经痛的疗效。方法回顾分析我院2000年10月～2006年7月37例继发性三叉神经痛的临床资料，其中胆脂瘤18例，脑膜瘤8例，听神经瘤6例，三叉神经鞘瘤5例，均经乙状窦后入路显微手术切除肿瘤。结果肿瘤全切23例，次全切除10例，部分切除4例。35例疼痛症状消失（32例立即消失，3例术后2个月消失），随访3个月～5年无复发；2例无效。发生暂时性面瘫6例，面部麻木6例，无颅内感染及脑脊液漏。结论经乙状窦后入路显微手术是治疗继发性三叉神经痛安全有效的方法。

康复指导对直肠癌Miles术后恢复期患者性生活质量的影响

目的：探讨康复指导对直肠癌Miles术后恢复期患者性生活质量的影响。方法：54例直肠癌Miles术后患者，其中32例(治疗组)于术后2周始给以人工肛门综合护理、性生活指导及心理干预等康复治疗。22例(对照组)只给以人工肛门一般性护理指导。利用0lson婚姻质量问卷(ENRICH)分别于术后2周及6个月对两组患者性生活质量进行评估。结果：治疗组治疗前后性生活因子分别为21．3l&;#177;9．18，33．20&;#177;10．76，差异有显著性意义(t=2．34，P=0．024)。对照组治疗前后分别为20．56&;#177;9．24，24．27&;#177;9．09，差异无显著性意义(t=1．7l，P=0．10)。结论：康复指导能改善Miles术后恢复期患者的性生活质量。     

内乳淋巴结在乳腺癌治疗中的重要性

目的探讨乳腺癌术后内乳淋巴结复发的原因,强调内乳淋巴结在乳腺癌治疗中的重要性。方法回顾性分析40例以内乳淋巴结转移为首先复发的女性乳腺癌患者的临床资料、初发病时的临床特征、手术方式、术后病理分期以及治疗经过。结果40例患者内乳淋巴结复发与患者年龄、经期状况、手术方式无关(P>0.05)。而与原发肿瘤直径、部位、腋窝淋巴结阳性数、临床病理分期相关(P<0.05)。结论位于乳腺内侧区、中央区的大块肿瘤(>3cm),腋窝淋巴结阳性数多(>3),且临床病理分期晚(IIb IIIab)的乳腺癌患者,内乳淋巴结转移机率较高,须加强术后综合治疗。
