Laparoscopic Local Resection Based on Sentinel Node Evaluation for Early Gastric Cancer: A Preliminary Report

We previously reported that lymphatic mapping using isosulfan blue can be used to identify sentinel nodes (SNs). This study was undertaken to evaluate the feasibility of using the SN technique in treating early gastric cancer and to explore its usefulness for minimal invasive surgery. Twenty-three patients with early gastric cancer who underwent SN biopsy were retrospectively evaluated. Based on SN evaluation, individualized surgery was performed in five patients with T1N0M0 gastric cancer. When pathological examination of frozen sections revealed metastasis in SNs, we performed a standard D2 gastrectomy. Laparoscopic local resection was applied when the SN biopsy was negative. Our results showed that the success rate with SN biopsy in early gastric cancer was 100%, as were the accuracy, sensitivity, and specificity. All five patients with early gastric cancer had SNs negative for metastases both by frozen section and by postoperative pathology. Thus, all these patients underwent laparoscopic local resection without extended lymphadenectomy. We conclude that SN biopsy is a useful tool to individualize the operative procedure, and laparoscopic local resection can be safely performed using SN guidance in selected patients with early gastric cancer.     

CD44v7/8基因表达与宫颈癌关系的探讨

目的探讨宫颈癌组织中CD44v7/8基因的异常表达及临床意义。方法1986～2000年沈阳医学院附属中心医院采用免疫组化的方法随机测定59例宫颈癌、18例尖锐湿疣和18例慢性宫颈炎组织中CD44v7/8基因的表达情况。结果宫颈癌、尖锐湿疣及慢性宫颈炎3种疾病中CD44v7/8表达阳性率分别为76.27%、11.11%和11.11%,宫颈癌组的CD44v7/8表达分别高于慢性宫颈炎组及尖锐湿疣组,且差异非常显著(P<0.01)。慢性宫颈炎组及尖锐湿疣组比较差异无显著性(P>0.05)。结论CD44v7/8蛋白的表达增强与宫颈癌的发生、发展及和局部浸润转移有关。     

抓住机遇构建和谐发展的疾病防控体系

近几年，国家加强了对突发公共卫生事件应急反应能力的要求，人民群众的防病意识不断增强，疾病控制中心传统工作模式受到了极大挑战。吉林省疾病预防控制中心作为省直卫生系统人事制度改革试点单位，于2003年11月初开始，历经2个月时间圆满完成了单位人事制度与分配制度改革工作，取得了令人满意的效果。现将我们的做法与体会总结如下。     

脊柱复合性损伤的救治风险与早期治疗

目的评估脊柱复合性损伤的特点和救治风险,探讨风险控制与最佳治疗的方法。方法采用AIS、ISS、TRISS及APACHEⅡ等评分方法对273例脊柱复合性损伤患者进行定量评价与救治分类,并依据伤后的损伤分级、参数评定及计量评分等指标进行量化分析和统计处理。结果颈椎合并伤115例,胸椎合并伤141例,胸腰椎合并伤294例,腰骶椎合并伤181例;患者的救治风险和脊椎伤的治疗选择或手术时机与其合并伤的解剖伤势及由此所构成的整体伤情密切相关(P<0.01或<0.05);高风险性伤员往往综合伤势严重,生存概率(Ps)趋低,并发症和死亡率高(P<0.01或<0.05)。结论脊柱脊髓损伤常合并有严重的多发伤,高危伤情不仅可增加其救治风险和脊柱伤的处理难度,且还易于丧失手术最佳时机。分类救治对伤员的风险控制和脊柱伤的专科治疗是有益的。     

多疗程治疗的癌症病人入院时的焦虑状态调查

[目的]了解恶性肿瘤病人反复多次入院治疗时的心理状态,通过护理干预帮助病人更快投入治疗情境.[方法]通过焦虑自评量表(SAS)进行心理测验,随机将病人分为对照组和实验组,针对结果分别进行相应护理,1周后复查.[结果]实验组和对照组护理后的SAS评分差异显著.[结论]癌症病人多疗程入院的病人焦虑状况严重,实施焦虑的支持护理及心理辅助,可较好地促进病人进入治疗角色,减少弃治轻生的发生.     

Stanford B型主动脉夹层腔内隔绝术中操作技巧

主动脉夹层腔内隔绝术于1998年由景在平教授完成国内首例，8年来该技术发展迅速，普及全国各省市，已有多家血管外科中心完成过百例手术。但不可否认该手术仍有一定风险，我科统计其围手术期死亡率约为3%。     

弧形切割吻合器在低位直肠癌超低位前切除术中的应用

目的总结弧形切割吻合器在低位直肠癌超低位前切除术中的应用价值。方法2005年12月至2006年9月选择56例低位直肠癌患者在全直肠系膜切除和侧方淋巴结清扫的基础上,应用弧形切割吻合器对直肠(肛管)残端进行切割、闭合,用33mm管型吻合器进行超低位结肠-直肠(肛管)吻合术。结果56例低位直肠癌患者术中没有发生切割和闭合不全的病例,吻合口无渗漏。手术后住院时间为(11.2±3.2)d,无死亡者。发生吻合口瘘2例(3.6%),经过局部引流而自然愈合1例,因直肠阴道瘘进行横结肠造口转流1例,无吻合口狭窄。结论弧形切割吻合器在低位直肠癌超低位前切除术中具有切割完整、闭合确实、吻合口瘘发生率低的优点,有良好的应用推广价值。

Correlates of lifetime suicide attempts among individuals with affective disorders in a Chinese rural community.

The aim of this study was to compare the demographic and clinical characteristics of individuals with affective disorders who had attempted suicide at some time in their lives and those who had not made a suicide attempt. In a Chinese rural community, individuals with suicide attempt (N = 30) and those without suicide attempt (N = 166) were assessed with Present State Examination (PSE). Attempters had a significantly higher level of family economic status, higher rate of lifetime depressed mood and hopelessness, and delusions than nonattempters. The logistic regression models also indicated that depressed mood and hopelessness were the most important predictors of suicide attempts. No significant difference in treatment condition was found between attempters and non-attempters. Early identification and interventions focusing on reducing depressed mood, hopelessness, and controlling psychotic symptoms may be helpful in reducing the risk of suicide attempts among individuals with affective disorders residing in the community.
