急性坏死性胰腺炎大鼠胰腺高迁移率族蛋白-1的表达及意义

目的探讨急性坏死性胰腺炎(ANP)大鼠模型胰腺组织高迁移率族蛋白-1(HMGB1)的表达及其意义。方法72只大鼠随机分成3组,即对照组、ANP组和正丁酸钠治疗组(治疗组)。逆行性胰胆管注射5%牛磺胆酸钠建立ANP模型。ELISA法检测血清TNF-α和IL-1β水平;RT-PCR法检测胰腺组织HMGB1 mRNA的表达,并观察其病理变化。结果ANP组血清TNF-α和IL-1β水平在ANP建模后6h达高峰,12h下降。ANP组大鼠胰腺组织HMGB1 mRNA表达水平在ANP后12h明显升高,至24h仍维持在较高水平。治疗组胰腺组织HMGB1 mRNA表达水平在ANP后12,24h明显低于ANP组(P<0.05),且同期胰腺损伤比ANP组轻(P<0.05)。建模后24h血清TNF-α和IL-1β水平ANP组与治疗组间差异无显著性。结论HMGB1作为晚期炎症因子参与了ANP的全身炎症反应。HMGB1抑制剂正丁酸钠能降低ANP大鼠胰腺组织HMGB1基因表达水平,减轻ANP胰腺组织的损伤。     

Tiam 1与胃癌细胞侵袭转移及与裸鼠移植瘤形成的关系

摘要：目的 检测胃癌细胞中T淋巴瘤侵袭转移诱导因子 1(Tiam 1)的表达，并分析其与胃癌细胞离体、在体侵袭转移能力的关系。方法 采用层粘连蛋白黏附法，由胃癌MKN 45细胞株(M0)中筛选获得高(MH)、低(ML)黏附亚株。应用RT PCR和定量细胞ELISA技术分别检测Tiam 1 mRNA与蛋白在M0，ML，MH细胞中的表达；应用Boyden小室法测定M0，ML，MH细胞的离体侵袭移行能力，并分析其与Tiam 1表达的关系。应用裸鼠接种法观察M0，ML，MH细胞的在体成瘤及转移能力。结果 MH细胞中Tiam 1 mRNA(RV=0.855±0.051)与蛋白的表达(RD=1.262±0.165)以及其离体侵袭转移能力(24.33±8.02，52.00±14.53)、在体裸鼠肺转移率(4/5=80%)均较M0细胞(RV=0.759±0.047，RD=0.911±0.104，11.67±3.79，26.00±9.54，2/5=40%)，ML细胞(RV=0.743±0.039，RD=0.892±0.101，9.67±3.06，23.67±8.50，1/5=20%)为强，统计学差异显著(P< 0.05)，但在M0，ML细胞间无统计学差异(P> 0.05)；Tiam 1表达水平与胃癌细胞的侵袭转移能力呈完全及高度正相关(P< 0.05)。结论 Tiam 1表达水平升高有可能促进胃癌细胞侵袭转移能力的增强。     

住院精神分裂症患者糖尿病患病率及相关因素分析

目的了解精神分裂症患者糖尿病的患病率,分析与糖尿病有关的临床危险因素。方法2006年1月1日在我院住院诊断符合CCMD-3诊断标准的精神分裂症患者,糖尿病诊断以我国现行临床诊断标准做出,对患者的一般情况、病程、家族史、血糖、血脂、服药情况等做相关统计分析。结果105例精神分裂症患者中患糖尿病的人数为19例,占18.1%。糖尿病发病与其年龄、病程、服药情况、高脂血症明显相关(P<0.05)。结论在对精神分裂症的收治中,其年龄、病程、服药、高脂血症等因素应视为患糖尿病的高危因素。     

宫腔镜诊治异常子宫出血432例中长期随访结果

目的 评价宫腔镜手术治疗异常子宫出血的中长期随访结果。方法 回顾分析我院2002年1月～2005年11月经宫腔镜诊治异常子宫出血且随访〉12个月的432例临床资料,诊断良性疾患391例[子宫内膜息肉96例（22.2%）,子宫黏膜下肌瘤38例（8.8%）,子宫内膜增生过长257例（59.5%）],行息肉或肌瘤切除、子宫内膜电切术;诊断子宫内膜腺癌41例（9.5%）,均为Ⅰ期,行经腹全子宫双附件切除、选择性盆腔淋巴结清扫术。结果 手术均获成功,未发生子宫穿孔等并发症。391例良性病变中,术后随访12～57个月,平均39个月,闭经占16.1%（63/391）,月经量少（每周期〈10片卫生巾）18.9%（74/391）,月经量正常（每周期10～20片卫生巾）58.3%（228/391）,术后改善不明显占6.6%（26/391）。26例月经量仍多者术后用孕酮治疗,7例有多发子宫肌瘤,术后32～44个月行全子宫切除术,8例复查阴道彩超子宫内膜厚度〉1.5 cm,术后5～19个月第2次行宫腔镜子宫内膜切除术,继续随访18～36个月,月经量少3例,闭经5例。41例子宫内膜癌Ⅰ期术后随访26～41个月,平均38个月,均无瘤存活。结论 异常子宫出血的治疗在结合病理学检查除外恶性病变后首选宫腔镜手术,严格B超监测是提高手术疗效和手术安全的保障。     

A Process and Outcomes Evaluation of the International AIDS Conference: Who Attends? Who Benefits Most?

The objective of the study was to conduct a process and outcomes evaluation of the International AIDS Conference (IAC). Reaction evaluation data are presented from a delegate survey distributed at the 2004 IAC held in Thailand. Input and output data from the Thailand IAC are compared to data from previous IACs to ascertain attendance and reaction trends, which delegates benefit most, and host country effects. Outcomes effectiveness data were collected via a survey and intercept interviews. Data suggest that the host country may significantly affect the number and quality of basic science IAC presentations, who attends, and who benefits most. Intended and executed HIV work‐related behavior change was assessed under 9 classifications. Delegates who attended 1 previous IAC were more likely to report behavior changes than attendees who attended more than 1 previous IAC. The conference needs to be continually evaluated to elicit the required data to plan effective future IACs.

Post‐traumatic reactions among rescue personnel 96 hours after the Hilton Hotel bombing in Sinai: The effect of previous exposure

This paper considers the immediate post‐traumatic reactions of rescue personnel who were exposed to the Hilton Hotel bombing in Sinai. The entire rescue personnel (n = 26) were assessed and separated into two groups on the basis of previous exposure to the same type of trauma. The results suggest that among rescue personnel, those with previous exposure had a lower level of post‐traumatic symptoms than those who were being exposed for the first time. This supports the hypothesis that previous exposure to the same type of trauma has an immunizing effect for subsequent same type of traumatic event among rescue personnel.
