小胶质细胞是存在于大脑中的吞噬细胞。自从二十世纪二十年代,小胶质细胞被发现以来,已经有大量关于它的研究。小胶质细胞体外培养研究已经大大增加了我们对这种细胞的了解。但是,小胶质细胞对脑内极其微小的变化都会产生反应,因此必须尽量在在体环境中对这种细胞进行研究。影像技术和转基因标记技术的发展使得研究者可以在在体环境中研究小胶质细胞。这些在体的研究改变了我们对于小胶质细胞的认识:即便在健康成年脑组织中,小胶质细胞也是活跃的。现在,越来越多的证据显示,小胶质细胞可以直接影响神经元的活动。因此,了解小胶质细胞,特别是其与神经元间的相互作用,具有重要的意义。本文即对研究小胶质细胞的3种动物模型进行综述,讨论各自的特点和优势,并列举近年来研究小胶质细胞所获得的成果。笔者认为,建立更多的研究小胶质细胞的动物模型有助于更全面的了解小胶质细胞的功能。

The authors focused on the current surgical treatment of resectable gastric cancer, and significance of peri- and post-operative chemo or chemoradiation. Gastric cancer is the 4th most commonly diagnosed cancer and the second leading cause of cancer death worldwide. Surgery remains the only curative therapy, while perioperative and adjuvant chemotherapy, as well as chemoradiation, can improve outcome of resectable gastric cancer with extended lymph node dissection. More than half of radically resected gastric cancer patients relapse locally or with distant metastases, or receive the diagnosis of gastric cancer when tumor is disseminated; therefore, median survival rarely exceeds 12 mo, and 5-years survival is less than 10%. Cisplatin and fluoropyrimidine-based chemotherapy, with addition of trastuzumab in human epidermal growth factor receptor 2 positive patients, is the widely used treatment in stage IV patients fit for chemotherapy. Recent evidence supports the use of second-line chemotherapy after progression in patients with good performance status

BACKGROUND Liver resection and radiofrequency ablation are considered curative options for hepatocellular *** choice between these techniques is still controversial especially in cases of hepatocellular carcinoma affecting posterosuperior segments in elderly *** To compare post-operative outcomes between liver resection and radiofrequency ablation in elderly with single hepatocellular carcinoma located in posterosuperior *** A retrospective multicentric study was performed enrolling 77 patients age≥70-years-old with single hepatocellular carcinoma(≤30 mm),located in posterosuperior segments(4a,7,8).Patients were divided into liver resection and radiofrequency ablation groups and preoperative,peri-operative and long-term outcomes were retrospectively analyzed and compared using a 1:1 propensity score *** After propensity score matching,twenty-six patients were included in each *** time and overall postoperative complications were higher in the resection group compared to the ablation group(165 min vs 20 min,Pperior segments in elderly is safe and feasible and ensures a short hospital stay,better quality of life and does not modify the overall and disease-free survival.

BACKGROUND Liver resection is the mainstay for a curative treatment for patients with resectable hepatocellular carcinoma(HCC),also in elderly *** this,the evaluation of patient condition,liver function and extent of disease remains a demanding process with the aim to reduce postoperative morbidity and *** To identify new perioperative risk factors that could be associated with higher 90-and 180-d mortality in elderly patients eligible for liver resection for HCC considering traditional perioperative risk scores and to develop a risk *** A multicentric,retrospective study was performed by reviewing the medical records of patients aged 70 years or older who electively underwent liver resection for HCC;several independent variables correlated with death from all causes at 90 and 180 d were *** coefficients of Cox regression proportional-hazards model for sixmonth mortality were rounded to the nearest integer to assign risk factors'weights and derive the scoring *** Multivariate analysis found variables(American Society of Anesthesiology score,high rate of comorbidities,Mayo end stage liver disease score and size of biggest lesion)that had independent correlations with increased 90-and 180-d mortality.A clinical risk score was developed with survival *** This score can aid in stratifying this population in order to assess who can benefit from surgical treatment in terms of postoperative mortality.
