World Journal of Gastroenterology 2008年第26期14卷 4146-4151页

作者： Cristiano Spada maria elena Riccioni Riccardo Urgesi Guido Costamagna Digestive Endoscopy Unit Catholic UniversityRome 00168Italy

Video capsule endoscopy is an attractive and patient- friendly tool that provides high quality images of the small bowel. Obscure gastrointestinal bleeding is the primary and most evaluated indication to capsule endoscopy;however,indications are expanding and a small number of preliminary reports have been presented concerning the role of video capsule endoscopy in the diagnosis of celiac disease. The purpose of this review is to update the current knowledge and to hypothesize on future perspectives of the use of video capsule endoscopy in patients with celiac disease.

苹果酸脱氢酶(MDH)广泛存在于动物、植物以及微生物体内,是生物体进行糖代谢的关键酶之一。在辅酶Ⅰ(NAD^+)或辅酶Ⅱ(NADP^+)的作用下,能够催化草酰乙酸和苹果酸之间相互转化。虽然目前真核微生物中MDH已被广泛研究,但是对原核生物中的这种酶却鲜有报道。因此,有必要对MDH的相关研究信息进行综述,以期更好地了解这种酶的功能。本文综述了细菌相关研究的各种数据信息,进一步挖掘MDH的分子多样性,包括分子量、低聚态、辅因子与底物的结合力,以及酶反应方向的差异等。通过对不同细菌来源的MDH的晶体结构的分析,可鉴别底物与辅因子结合的部位以及形成二聚体的重要残基。对这些结构信息的了解将有利于指导研究人员对酶的结构进行修饰从而提高其催化能力,比如增加酶的活性、辅助因子的结合能力、底物特异性和热稳定性等。另外,本文通过分析比较MDH系统发生树的重建,将其蛋白超家族分成两个主分支,同时在古生菌、细菌和真核微生物等不同细胞的MDH之间建立联系。

Selective intestinal decontamination for the prevention of early bacterial infections after liver transplantation

引用

World Journal of Gastroenterology 2016年第26期22卷 5950-5957页

作者： elena Resino Rafael San-Juan Jose maria Aguado Unit of Infectious Diseases 12 de Octubre University Hospital

Bacterial infection in the first month after liver transplantation is a frequent complication that poses a serious risk for liver transplant recipients as contributes substantially to increased length of hospitalization and hospital costs being a leading cause of death in this period. Most of these infections are caused by gramnegative bacilli, although gram-positive infections, especially Enterococcus sp. constitute an emerging infectious problem. This high rate of early postoperative infections after liver transplant has generated interest in exploring various prophylactic approaches to surmount this problem. One of these approaches is selective intestinal decontamination(SID). SID is a prophylactic strategy that consists of the administration of antimicrobials with limited anaerobicidal activity in order to reduce the burden of aerobic gram-negative bacteria and/or yeast in the intestinal tract and so prevent infections caused by these organisms. The majority of studies carried out to date have found SID to be effective in the reduction of gram-negative infection, but the effect on overall infection is limited due to a higher number of infection episodes by pathogenic enterococci and coagulase-negative staphylococci. However, difficulties in general extrapolation of the favorable results obtained in specific studies together with the potential risk of selection of multirresistant microorganisms has conditioned controversy about the routinely application of these strategies in liver transplant recipients.

Tumor biopsies may help to reliably distinguish hepatocellular carcinoma(HCC) from other tumors, mostly cholangiocarcinoma as well as to identify the patient populations who most benefit from target-driven HCC treatments, in order to improve the success rate of experimental therapies. Clarifying tumor biology may also lead to identify biomarkers with prognostic role and/or enabling to predict response or resistance to therapies. Recently, clinical trials have more efficiently included biomarker endpoints and increasingly collected tumor tissue from enrolled patients. Due to their frail status and sometimes fast-progressing disease, the performance status of patients with HCC progressing on first-line therapy can deteriorate quickly, preventing their enrollment in clinical trials. However, the challenge of identifying the proper patient at the proper time can be overcome by periodic inter-department meetings involving the key specialists taking care of HCC patients, and solid networks between research centers and referring institutions. An early planned biopsy would also facilitate timely inclusion of patients in biology-driven clinical trials. Ultimately, institution of multidisciplinary teams can optimize treatment choice, biopsy timing, and quick enrollment of patients in clinical trials, before their performance status deteriorates.
