3Imaging of liver cancer显示文摘Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality.Ben Ariff Claire R Lloyd Sameer Khan Mohamed Shariff Andrew V Thillainayagam Devinder S Bansi Shahid A Khan Simon D Taylor-Robinson Adrian KP Lim 2009World Journal of Gastroenterology2009,15,11:4
4Treatment of Helicobacter pylori in surgical practice:A randomised trial of triple versus quadruple therapy in a rural district general hospital显示文摘AIM: To compare a lansoprazole-based triple versus quadruple therapy for Helicobacter pylori (H pylori) eradication with emphasis on side effect prof ile,patient compliance and eradication rate at a rural district general hospital in Wales,United Kingdom. METHODS: One hundred one patients with H pylori infection were included in the study. Patients were randomised to receive triple therapy comprising of lansoprazole 30 mg,amoxycillin 1 g,clarithromycin 500 mg,all b.d. (LAC),or quadruple therapy comprising of lansoprazole 30 mg b.d.,metronidazole 500 mg t.d.s.,bismuth subcitrate 240 mg b.d.,and tetracycline chloride 500 mg q.d.s. (LMBT). Cure was defi ned as a negative 13C urea breath test 2 mo after treatment. RESULTS: Seven patients were withdrawn after randomisation. Fifty patients were assigned to LAC group and 44 to LMBT group. The intention-to-treat cure rates were 92% and 91%,whereas the per-protocol cure rates were 92% and 97%,respectively. Side effects were common,with 56% experiencingmoderate to severe symptoms in the LAC group and 59% in the LMBT group. Symptoms of vomiting,diarrhoea and black stools were significantly more common in the LMBT group. Patient compliance was 100% for triple therapy and 86% for quadruple therapy (P < 0.01). One-third of patients in both groups were still taking acid-reducing medications at six-month follow-up. CONCLUSION: One-week triple and quadruple therapies have similar intention-to-treat eradication rates. Certain side effects are more common with quadruple therapy,which can compromise patient compliance. Patient education or modifi cations to the regimen are alternative options to improve compliance of the quadruple regimen.Siok Siong Ching Sivakumaran Sabanathan Lloyd R Jenkinson 2008World Journal of Gastroenterology2008,14,24:2
5Selective Deactivation of Gibberellins below the Shoot Apex is Critical to Flowering but Not to Stem Elongation of Lolium显示文摘赤霉素(气体) 在 GA1 的合成在植物高度和基因块引起戏剧的增加解释相形见绌 Mendel 的豌豆。为 flowering,是 GA5 重要在长天(LD ) 应答的草, Lolium。当我们这里出现,因为他们被 C-2 hydroxylation 在射击顶下面撤销, GA1 和 GA4 为 flowering 在他们的有效性被限制。相反,因为它的结构的保护, GA5 是有效的。切除植物的射击尖端很快降级[14C ] GA1,[14C ] GA4,并且[14C ] GA20 (>80% 在 6 ? h ) ,然而并非[14C ] GA5。偶然,编码二 2-oxidases 的基因和通常认为的 1617-epoxidase 最就在射击顶下面被表示(< 3 ? 公里) 。进一步击倒不成熟的茎(> 4 ? 公里) ,这些 GA 释放基因的表示被减少,那么允许 GA1 和 GA4 支持接近顶点的茎延伸。随后, GA 降级在花地导致的射击尖端和这些气体衰退能为花的开发变得活跃。稳定 GA4 的结构的变化证实在 florigenicity 和限制 GA 2-hydroxylation 之间的连接(例如 2-hydroxylation 和 C-2 di-methylation ) 。另外,一个 2-oxidase 禁止者(Trinexapac 乙醇) 提高了应用 GA4 的活动,作为做了在 16,17-dihydro 气体或在 C-13 hydroxylation 以后限制 C-16,17 epoxidation。总的来说,就在射击顶下面的 GA1 和 GA4 的释放有效地在 Lolium 限制他们的 florigenicity,相反地,与 GA5,对释放的 C-2 和 C-13 保护允许它的高 florigenicity。思索地,在草的射击顶的 GA 存取的如此的差别可能为把花的正式就职与开花期出现分开是重要的并且能因此在草食动物 predation 的条件下面影响他们的幸存。Rod W.

7膜型巨噬细胞集落刺激因子对人脑胶质细胞瘤的免疫治疗作用显示文摘摘要 目的 探讨基因转染膜型巨噬细胞集落刺激因子(mM-CSF)对U251MG人脑胶质瘤细胞的免疫治疗作用。方法 用逆转录病毒载体将mM-CSF基因转入U251MG细胞,采用流式细胞术检测mM-CSF的表达;通过细胞毒性实验、兔疫组化方法以及观察转染细胞在免疫缺陷小鼠体内的生长情况研究mM-CSF对U251MG细胞的作用。结果①获得了表达mM-CSF的MG-2F11细胞;②大鼠巨噬细胞、人外周血淋巴细胞(PBL)和人单核细胞均可杀伤MG-2F11细胞,但不能杀伤U251MG母细胞;③接种瘤细胞到裸小鼠皮下18 h后,侵入MG-2F11肿瘤的巨噬细胞明显多于侵入MG-VV(仅转染病毒载体的U251MG细胞)肿瘤的巨噬细胞;④接种MG-2F11细胞的8只裸小鼠均无肿瘤生长,而接种MG-VV细胞的8只裸小鼠中的7只有肿瘤生长(P<0.01);另一免疫缺陷更严重的NIH-bg-nu-xidBR 小鼠,接种MG-2F11细胞后8只中的1只有肿瘤生长,而接种MG-VV细胞后8只中的7只有肿瘤生长(P<0.01)。结论mM-CSF转染的人脑胶质瘤细胞致瘤性降低,有进一步对其进行临床研究的必要。陈义军 Cheri Lloyd Ramon Sanchez Martin R Jadus H Terry Wepsic 2002中华神经外科疾病研究杂志2002,1,3:2
