成人成骨细胞与珊瑚羟基磷灰石的体外生物相容性

目的：研究成人骨髓成骨细胞与珊瑚羟基磷灰石（carolline hydroxyapatite,CHA)在体外培养条件下的生物相容性。方法：抽取健康成人骨髓组织，置于含体积分数为10％胎牛血清的DMEM培养基中培养，传代后改用含地塞米松、β-甘油磷酸钠和维生素C的条件培养基培养，分为CHA复合细胞组和单纯细胞组，不同时间用倒置相关显微镜，HE染色光镜及扫描电镜观察，MTT法进行细胞增殖测定，并进行细胞微量蛋白含量和碱性磷酸酶的定量检测，结果：成人骨髓成骨细胞体外培养时复合或不复合CHA均生长良好，表现出典型成骨细胞的形态特征和生物学特性，CHA利于细胞的贴附，生长与增殖，并对细胞的功能无不良影响，结论：CHA是较理想的骨组织工程支架材料，成骨细胞复合CHA用于骨缺损的修复，具有广阔的临床应用前景。

强化过程控制和精细化管理保证护理质量持续改进

质量管理是医院生存和发展的战略战术。质量就是生命,质量就是效益,21世纪护理质量的起步要求是护理质量管理者应在缺陷预防和质量持续改进方面做出尝试,护理管理者应在推行精细化管理,强化护理过程控制方面做出努力,以满足广大病人的健康服务需求。1质量发展及其概念1.1护理质量管理的发展阶段美国护理质量管理大体经历了3个历史性发展阶段:20世纪70年代“质量控制阶段”,20世纪80年代“质量保证阶段”,20世纪90年代“质量促进阶段”。质量控制阶段的主要特点:①由质量管理人员发现已出现的质量问题,然后做出处理;②技师评价方式为依照标准…     

教师心理问题的职业原因及干预策略

教师心理健康是学校心理健康教育的重要方面。教师职业的一些特点，如非对称互动、角色问题、工作超负荷、待遇较低等对教师的“理健康有不容忽视的负性影响。应在优化教师工作与生存环境、改善教育管理、提高教师社会地位和待遇、自我调节等方面采取积极的干预以促进教师的心理健康．     

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.
