Objective. Stents have been used to relieve pancreatic duct stricture and upstream dilatation. However,many of these stents are straight-type stents originally manufactured for biliary use. A plastic stent that was developed for use in the pancreatic duct was used in this study and its usefulness investigated. Material and methods. The stent (s-type stent: 10 Fr in diameter) has two alternate flexions and the shape resembles the tilde mark “～" in appearance. After obtaining informed consent, stents were placed in 20 patients with abdominal pain caused by chronic pancreatitis and stricture of the distal main pancreatic duct. The stents were removed according to the clinical manifestations and replaced with new ones if the stricture persisted. Results. In total, 33 stents were placed in 20 patients. Pain relief was attained in 19 patients (95%). The stricture improved after one stenting in 8 patients (40%). Owing to persistent stricture, the stenting was repeated in 11 patients. The 50%stent indwelling period was 369.0 days. No proximal or distal migration of the stent occurred and there were no serious complications. Conclusions. In view of its long durability as a stent and no migration, the s-stent is safe and useful for the management of pancreatic ductal strictures in patients with chronic pancreatitis.

Black liver is a common finding in Dubin-Johnson syndrome (DJS), which is caused by the lack of multidrug resistance-as-sociated protein 2 (MRP2). Impaired excretion of epinephrine metabolites is believed to be a cause of black liver in DJS. Recently, we experienced a patient with black liver whose serum bilirubin level was normal. Coarse brown granules were observed in the hepatocytes, and this finding closely resembled that observed in DJS. However, the granules were negative for Schmorl staining. The MRP2 gene did not show any mutation. Immunostaining study demonstrated MRP2 protein expression in the liver, and it was localized in the canalicular membranes of hepatocytes. This case illustrates for the first time that DJS is not the only cause of black liver.

AIM: To investigate the feasibility of cold snare polypectomy(CSP) in ***: The outcomes of 234 non-pedunculated polyps smaller than 10 mm in 61 patients who underwent CSP in a Japanese referral center were retrospectively analyzed. The cold snare polypectomies were performed by nine endoscopists with no prior experience in CSP using an electrosurgical snare without ***: CSPs were completed for 232 of the 234 polyps. Two(0.9%) polyps could not be removed without electrocautery. Immediate postpolypectomy bleeding requiring endoscopic hemostasis occurred in eight lesions(3.4%; 95%CI: 1.1%-5.8%), but all were easily managed. The incidence of immediate bleeding after CSP for small polyps(6-9 mm) was significantly higher than that of diminutive polyps(≤ 5 mm; 15% vs 1%, respectively). Three(5%) patients complained of minor bleeding after the procedure but required no intervention. The incidence of delayed bleeding requiringendoscopic intervention was 0.0%(95%CI: 0.0%-1.7%). In total, 12% of the resected lesions could not be retrieved for pathological examination. Tumor involvement in the lateral margin could not be histologically assessed in 70(40%) ***: CSP is feasible in Japan. However, immediate bleeding, retrieval failure and uncertain assessment of the lateral tumor margin should not be underestimated. Careful endoscopic diagnosis before and evaluation of the tumor residue after CSP are recommended when implementing CSP in Japan.

1997年 1 0月中国科学院上海天文台与美国宇航局Goddard空间飞行中心(GSFC)成功组织实施了亚太地区空间地球动力学研究计划 (APSG)首期联测中的VLBI观测 .共 6个VLBI站参加 ,包括中国上海和乌鲁木齐站、美国阿拉斯加Gilcreek站和夏威夷Kokee站、日本鹿岛 (Kashima)站及澳大利亚塔斯玛尼亚的Hobart站 .各站之间的基线长度为 1 90 0～ 1 1 0 0 0km ,基线测量重复率约为 1 0× 1 0 -9.利用上述台站以往的VLBI观测 ,并结合全球VLBI观测数据进行了综合解算 ,获得了上述 6个VLBI站的基线变化率及台站的运动速率 .特别是检测到上海台和乌鲁木齐站相对于欧亚板块稳定区域分别存在向东 8mm/a和向北偏东 1 4mm/a的运动。
