THE preparation of high-temperature superconducting (HTSC) wires or tapes is very important for the power application of HTSC. High-J_c properties of Y-Ba-Cu-O thin film at liq uid-nitrogen temperature are very attractive not only for small-sized electronic devices, but also for large-scale applications such as high-power transmission cables, high-field magnets and large-scale microwave components. Large-current power application would be achieved if high-J_c YBCO films were grown on practical cheap and flexible metallic substrates. An yttria-stabi-

World Journal of Gastroenterology 2017年第11期23卷 2086-2089页

Massive global spread of multidrug-resistant(MDR) Salmonella spp. expressing extended-spectrum beta-lactamase(ESBL) and additional resistance to fluoroquinolones has often been attributed to high international mobility as well as excessive use of oral antibiotics in livestock farming. However, MDR Salmonella spp. have not been mentioned as a widespread pathogen in clinical settings so far. We demonstrate the case of a 25-year-old male with primary sclerosing cholangitis who tested positive for MDR Salmonella enterica serotype Choleraesuis expressing ESBL and fluoroquinolone resistance. The pathogen was supposedly acquired during a trip to Thailand, causing severe fever, cholangitis andpancreatitis. To our knowledge, this is the first report of Salmonella enterica serotype Choleraesuis in Europe expressing such a multidrug resistance pattern. ESBL resistance of Salmonella enterica spp. should be considered in patients with obstructive biliary tract pathology and travel history in endemic countries.

Hepatobiliary cystadenomas (HBC) and cystadenocarci- nomas are rare cystic lesions. Most patients with these lesions are asymptomatic, but presentation with ob- structive jaundice may occur. The first patient presented with intermittent colicky pain and recurrent obstructive jaundice. Imaging studies revealed a polypoid lesion in the left hepatic duct. The second patient had recurrent jaundice and cholangitis. Endoscopic retrograde cholan- giopancreatography (ERCP) showed a cystic lesion at the confluence of the hepatic duct. In the third patient with intermittent jaundice and cholangitis, cholangioscopy re- vealed a papillomatous structure protruding into the left bile duct system. In the fourth patient with obstructive jaundice, CT-scan showed slight dilatation of the intrahe- patic bile ducts and dilatation of the common bile duct of 3 cm. ERCP showed filling of a cystic lesion. All patients underwent partial liver resection, revealing HBC in the specimen. In the fifth patient presenting with obstructive jaundice, ultrasound examination showed a hyperecho- genic cystic lesion centrally in the liver. The resection specimen revealed a hepatobiliary cystadenocarcinoma. HBC and cystadenocarcinoma may give rise to obstruc- tive jaundice. Evaluation with cross-sectional imaging techniques is useful. ERCP is a useful tool to differentiate extraductal from intraductal obstruction.

AIM: To evaluate the results of the treatment of simple liver cysts (solitary and multiple) and polycystic liver disease (PLD) using percutaneous sclerotherapy and/or surgical procedures in a single tertiary referral centre. METHODS: Retrospective analysis of 54 patients referred for evaluation and possible treatment of simple liver cysts (solitary and multiple) and PLD, from January 1997 to July 2006. RESULTS: Simple liver cysts were treated in 41 pts (76/) with a mean size of 12.6 cm. The most common reason for referral was abdominal pain or discomfort (85/). Percutaneous sclerotherapy was performed as initial treatment in 30 pts, showing cyst recurrence in 6 pts (20/). Surgical treatment was initially performed in 11 pts with cyst recurrence in 3 pts (27/). PLD was treated in 13 pts (24/) with a mean size of the dominant cyst of 13 cm. Percutaneous sclerotherapy for PLD was performed in 9 pts with recurrence in 7 pts (77.8/). Surgical treatment for PLD was undertaken in 4 pts (30.8/) with recurrence in all. Eventually, 2 pts with PLD in the presence of polycystic kidney disease underwent liver-and kidney transplantation because of deterioration of liver and kidney function. CONCLUSION: The majority of patients with simple liver cysts and PLD are referred for progressive abdominal pain. As initial treatment, percutaneous sclerotherapy is appropriate. Surgical deroofing is indicated in caseof cyst recurrence after percutaneous sclerotherapy. However, the results of percutaneous sclerotherapy and surgical treatment for PLD are disappointing. Partial liver resection is indicated when there is suspicion of a pre-malignant lesion.

背景心血管疾病(CVD)已经成为主要的死亡原因之一。在过去的10年,维生素D在骨骼之外的其他多种疾病(包括CVD)中的作用引起了广泛的关注。血液循环中甲状旁腺激素(PTH)是骨骼与矿物质代谢的主要调节激素,可以刺激维生素D向活性形式转化。研究表明,PTH不仅是维生素D代谢状态的生物标记,而且是独立的心血管危险因素,参与了CVD的进展。目的该文主要对PTH与CVD相关的文献进行总结。结果越来越多的证据表明,较高浓度PTH与CVD相关。PTH过多可能影响潜在的CVD发病机制,包括心脏生物标记物、心脏结构及高血压等,进而促进CVD的发生。基于现有的证据,在一般人群中补充维生素D、抑制PTH是否对心血管健康有益,还需要进一步证实。结论老年人群中PTH过高比较常见。由于高浓度PTH可能对心血管健康不利,所以采用维生素D治疗或PTH特异性抑制剂治疗,以降低PTH浓度可能有利于阻止心脏疾病,降低CVD发生率。然而,目前的研究证据还不足以支持在一般人群中通过提高维生素D或降低PTH水平来预防CVD。
