1Chest wall metastasis from unknown primary site of hepatocellular carcinoma显示文摘独居的变形肝细胞癌的以前的报告是稀罕的。因为这个肿瘤有一种不同处理形式和预后,精确鉴别诊断是必要的。这里,我们从肝细胞癌的未知主要地点报导独居的胸壁转移的一个稀罕案例。它包含因为一个摸得出的左上面的胸壁团,进入我们的医院的一个 51 岁的人。团是 resected,病理学的检查证实了变形肝细胞癌的诊断。尽管有我们的调查,没有证据被发现那显示肝细胞癌的主要起源。四个月以后,因为脊髓压缩,病人在第三和第四胸的椎骨,脊椎再被招收。突现的 decompressive 椎板切除术被执行,显微镜的特征 4 个月早揭示了象起始的胸壁团 resected 的一样的病理。在一年以后,后续腹的计算断层摄影术(CT ) 仍然没揭示主要肝细胞的证据癌。Yil Sik Hyun Ho Soon Choi Joong Ho Bae Dae Won Jun Hang Lak Lee Oh Young Lee Byung Chul Yoon Min Ho Lee Dong Hoo Lee Choon Shuk Kee Jung Ho Kang Moon Hyang Park 2006World Journal of Gastroenterology2006,12,13:4
2Do we have enough evidence for expanding the indications of ESD for EGC?显示文摘Endoscopic submucosal dissection(ESD) is the most advanced and representative technique in the field of therapeutic endoscopy and has been used for the treatment of gastrointestinal neoplasms,including early gastric cancer.The major difference and advantage of ESD compared to existing endoscopic resection techniques,such as endoscopic mucosal resection(EMR) and polypectomy,are the width and depth of the resection.Newly developed cutting devices,distal attachable endoscopic accessories,and an advanced electrosurgical unit have helped to overcome the limitations of therapeutic endoscopy in terms of lesion size,location,presence of fibrotic scarring,and accompanying ulcers.As a result,the indications for ESD have been expanded from the classical indication for EMR and polypectomy,and there is now support for a further expansion of ESD indications.At present,the most critical factor to consider in the decision of whether to perform ESD is the probability of unexpected lymph node metastasis.The guidelines for ESD are continually being updated and debated.In this review,we discuss the strengths and weaknesses of the expanded guidelines,based on evidence found in the literature.Hang Lak Lee Chang Hwan Choi Dae Young Cheung 2011World Journal of Gastroenterology2011,17,21:4
3乙肝病毒复制与非复制状态细胞免疫功能的研究显示文摘本文对乙型肝炎患者(简称乙肝)有、无乙肝病毒复制者的细胞免疫功能状态进行了检测,以HBeAg、HBVDNA-PCR的均阳性为复制指标,HBeAg、HBeAg HBVDNA-PCR均阳性为非复制指标,52例患者,复制及非复制组各26例。结果为:乙肝病毒(HBV)复制组CD_4^+/CD_3^+为1.36±0.34,非复制组2.99±0.061,P<0.05;NK细胞活性测定复制组为40.01±12.48,非复制组68.80±9.82,P<0.01; LAK细胞活性测定,复制组为44.20±11.51,非复制组为67.90±9.82,P<0.01结果表明,有病毒复制者的细胞免疫功能明显低下,说明细胞免疫功能状况对HBV复制具有明显影响,此为乙肝具有病毒复制者,治疗上使用免疫促进剂提供了依据。郝晓 崔东来 姚希贤 张晓岚 靳洪涛 本文对乙型肝炎患者(简称乙肝)有 无乙肝病毒复制者的细胞免疫功能状态进行了检测 以HBeAg HBVDNA-PCR均阳性为复制指标 HBaAg HBeAg HBVDNA-PCR均阴性为非复制指标.52例患者 复制及非复制组各26例.结果为:乙肝病毒(HBV)复制组CD_4~+/CD_a~+为1.36±0.34 非复制组2.99±0.61 P<0.05 NK细胞活性测定复制组为40.01±12.48 非复制组68.80±9.82 P<0.01 LAK细胞活性测定 复制组为44.20±11.51 非复制组为67.90±9.82 P<0.01.结果表明:有病毒复制者的细胞免疫功能明显低下.说明细胞免疫功能状况对HBV复制具有明显影响 此为乙肝具有病毒复制者 治疗上使用免疫促进剂提供了依据. 1998临床荟萃1998,13,10:3
4Effect of seismic waves on the hydro-mechanical properties of fractured rock masses显示文摘The transmission of seismic waves in a particular region may influence the hydraulic properties of a rock mass, including permeability, which is one of the most important. To determine the effect of a seismic wave on the hydraulic behavior of a fractured rock mass, systematic numerical modeling was conducted. A number of discrete fracture network(DFN) models with a size of 20 m × 20 m were used as geometrical bases, and a discrete element method(DEM) was employed as a numerical simulation tool. Three different boundary conditions without(Type Ⅰ) and with static(Type Ⅱ) and dynamic(Type Ⅲ) loading were performed on the models, and then their permeability was calculated. The results showed that permeability in Type Ⅲ models was respectively 62.7% and 44.2% higher than in Type I and Type Ⅱ models. This study indicates that seismic waves can affect deep earth, and, according to the results, seismic waves increase the permeability and change the flow rate patterns in a fractured rock mass.Meysam Lak Alireza Baghbanan Hamid Hashemolhoseini 2017Earthquake Engineering and Engineering Vibration2017,16,3:2
