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.

100例性病患者心理健康状况调查分析

目的：探讨性病患者的心理健康状况,为临床治疗和护理提供依据。方法：采用症状自评量表（SCL-90）对100例性病患者的心理健康状况进行测验。结果：100例性病患者SCL-90检测的阳性率为51%,阳性样本因子分居前的是敌对、强迫症状、抑郁、人际敏感。结论：性病患者广泛存在的心理问题,在药用治疗的同时应注意心理方面的治疗和疏导。     

The genetic and epigenetic basis of ependymoma

Introduction  

Although ependymoma is the third most common pediatric brain tumor, we know little about the genetic/epigenetic basis of its initiation, maintenance, or progression. This is due in part to the heterogeneity of the disease, as well as the small sample size of the cohorts analyzed in most studies.     

广西边远少数民族学生体型及体质量指数3年追踪**

背景: 前期研究表明广西18~22岁少数民族学生体质量偏轻。 目的：拟进一步了解广西2645名少数民族学生体型及体质健康状况，寻找影响的关联因子。 设计、时间及地点：追踪调查，于2004-12/2007-12在广西民族大学完成。 对象：广西民族大学2003/2005三次体质健康测试的全体学生2 645人。男1 337人，女1308人，年龄为18~20岁，共15个民族。 方法：根据2003年教育部、体育总局《学生体质健康标准（试行方案）》和实施方法分为形态指标、技能指标和身体素质指标3大类。对2 645名少数民族身体机能与体质量指数变化的跟踪调查。 主要观察指标：身高、体质量、肺活量、立定跳远、坐位体前屈、体质量指数。 结果：①广西民族大学2003级学生大学3年期间男生身高、体质量增长率比全国同期多2.45%，身体形态发育正处于高峰期，女生成偏瘦型体型，身体形态发育情况总体欠佳。②男女学生在刚入校时肺活量机能较差，远远低于同期全国平均水平。3年后男生肺活量增长率为11.55%、女生肺活量增长率为27.72%，分别高于全国同期肺活量增长率。③坐位体前屈机能高于同期全国平均水平，男生呈逐年上升趋势，同期全国男性呈下降趋势；同期全国乡村女生均呈逐年上升趋势。④立定跳远机能提高较大，3年后增长率为18.15%，明显高于全国同期立定跳远增长率水平的2.61%。女生立定跳远机能总体不如全国同期水平。⑤体质量指数总体与同期全国乡村男女学生体质量指数比较稍低一些(P < 0.01)。 结论：2 645名少数民族学生发育正处于高峰期；肺活量机能不及全国同期平均水平。男女体质量指数分布有所不同，体质量偏轻者女生多于男生，表明学生营养状况总体欠佳。     

Abnormal fluorine-18-fluorodeoxyglucose uptake in benign esophageal leiomyoma

A benign esophageal leiomyoma with abnormally increased fluorine-18-fluorodeoxyglucose uptake on positron emission tomography (PET) was resected thoracoscopically. The tumor, of which the maximum standardized uptake value of the lesion was 4.7, was well defined and 38 mm in diameter. Neither mitotic activity nor degeneration was found histologically; and immunoreactivity for CD34, CD117, MIB-1, and glucose transporter-1 was negative immunohistochemically. A diagnosis of gastrointestinal stromal tumor was ruled out by an oncogenic kinase gene mutation study. This case cautions against PET-dependent evaluation for malignant potential of esophageal submucosal tumors.
