老年人腹腔镜胆囊切除术118例报告

目的探讨老年人腹腔镜胆囊切除术（laparoscopic cholecystectomy，LC）的特点。方法回顾性分析2000年1月～2005年1月我院收治的118例老年病人LC的临床资料。结果116例顺利施行LC，中转开腹手术2例，其中1例为胆囊管开口于胆总管下端，另1例胆总管损伤。LC手术时间30～120min，平均50min。术后均恢复顺利。术后住院3～7d，平均4．5d。1例胆总管损伤术后随访2年6个月，有短暂的腹痛和发热，应用抗生素2—5d后症状消失，无胆道狭窄和胆道结石。余117例术后随访6～12个月，平均10．5月，无腹痛、发热、黄疸等并发症。结论老年人可耐受LC，且安全可靠，充分的围手术期处理、仔细的手术操作是成功的关键。     

Atypical fibroxanthoma and squamous cell carcinoma of the conjunctiva in xeroderma pigmentosum.

Patients with xeroderma pigmentosum (XP) have defective DNA repair and a high predisposition to developing abnormalities and neoplasia in the sun-exposed areas of the skin and mucous membranes. The most common tumors reported in patients with XP are squamous cell carcinomas, basal cell carcinomas, and melanomas. Atypical fibroxanthoma (AFX) is a pleomorphic tumor that arises predominantly in the sun-damaged skin of the head and neck regions of the elderly. We describe a unique case of a 6-year-old African American boy with XP who developed an atypical fibroxanthoma and 2 squamous cell carcinomas in the conjunctiva. The clinical and histopathologic findings of AFX are discussed.

131Ⅰ治疗Graves病剂量探讨

目的　探讨1 31 Ⅰ治疗Graves病时 ,不同的剂量计算方法与治愈率以及治疗后并发症的关系。方法　在计算治疗Graves病所需1 31 Ⅰ时 ,分别采取不同的两种计算方法 ,观察两者治愈率及并发症的发生情况 ,并做多因素对比分析。结果　治疗组较对照组 1次治愈率提高约 12 % ,近期甲状腺功能减退延续为永久性甲状腺功能减退者亦明显减少 ,治疗效果明显优于后者。结论　1 31 Ⅰ治疗剂量计算时 ,既要有公式的规范性 ,又要有根据具体情况调节的灵活性 ,即可明显提高治疗效果     

围术期维持活体部分移植小肠血供的措施

目的：探讨围术期维持移植小肠血液灌注的方法，方法：男，18岁，短肠综合征患者，全麻下接受其父亲供给末段回肠150cm，行活体部分小肠移植，围主期维持出入量平衡，中度等容血液稀释，选用扩血管药，防止血管痉挛，以及抗凝治疗，结果：术的31d脱离肠外营养，至今已术后34mo，未发生移植小肠明显缺血性改变。结论：采用上述方法匀是维持围术期移植小肠血供的重要措施。     

腺病毒载体介导CTLA4Ig基因治疗小鼠变应性鼻炎

目的 检测CTLA4Ig-重组腺病毒载体（Ad-CTLA4Ig）在变应性鼻炎治疗中的作用。方法 采用卵清蛋白（OVA）致敏和激发诱导小鼠变应性鼻炎。实验组在OVA激发前30min予以Ad-CTA4Ig腹腔注射。未转CTLA4IgcDNA的腺病毒载体（Adv）作对照。比较各组动物鼻部症状和鼻粘膜形态学改变，并采用ELISA法测定血清中OVA－特异性IgE水平。结果 CTLA4Ig重组腺病毒实验组小鼠鼻部症状和鼻粘膜病理改变不明显，并且血清中OVA－特异性IgE水平明显低于对照组（P＜0.05）。结论 Ad-CTLA4Ig可防治小鼠应变性鼻炎的发生，提示CTLA4Ig-重组腺病毒载体有可能运用于临床变应性鼻炎的治疗。     

驼背二种截骨术远期效果对比

作者对６３２例强直性脊柱炎并驼背畸形施行二种脊柱截骨矫治术，对其中１３５例病人进行了６～１０年观察，结果表明：７１例椎弓椎体联合截骨效果较好，驼背复发平均３．２°。而６４例椎板截骨效果略差，驼背平均复发１３．５°。经统计学处理，两者对比有显著的统计学意义（ｐ＜０．０１）。作者认为病变未完全静止，截骨术式的选择，术中身体重心前移未彻底纠正，以及外固定时间过短等是影响远期效果的因素。     

Attitudes towards mental illness: testing the contact hypothesis among Chinese student nurses in Hong Kong

This study investigated whether previous contact with mental illness affected the attitudes to mental illness (AMI) of general student nurses in Hong Kong — the contact hypothesis. We employed a quasi-experimental design. We compared the attitudes to mental illness of students who had previous contact with mental illness through having taken a psychiatric secondment with those who had not taken a psychiatric secondment. Also, we compared the AMI of: students who had taken other courses related to mental illness with those who had not; those who had a family history of mental illness with those who had not; and those who lived with a mentally ill relative with those who did not. We found that previous contact with mental illness had no significant effect on the attitudes to mental illness of the students. In other words our findings do not support the contact hypothesis. Our sample expressed positive general attitudes to mental illness when presented with general issues about mental illness. However, their attitudes were less positive when presented with specific issues about mental illness that might impinge upon their daily lives. We discuss the implications of these findings for mental health nursing practice, education and research.
