BACKGROUND:Obstructive jaundice is a common condition in advanced digestive *** procedures can improve quality of life and allow patients to attempt a systemic *** anastomosis is still the procedure of choice for patients in many *** a surgical bypass is not possible,biliary drainage can be done by placing endoscopic or transparietal stents,which are less durable methods even when an expandable stent is employed. METHODS:A 47-year-old male with an excellent clinical status and a previous cholecystectomy and an exploratory laparotomy for advanced gastric cancer was referred with obstructive jaundice.A preoperative CT scan showed a dilated bile duct and a small mass at the distal hepatic *** other signs of metastasis were found.A surgical bilioenteric anastomosis was *** surgery,a distal choledochal obstruction and a mesenteric retraction by a lymph node mass prevented the jejunum to ascend for a bilioenteric anastomosis. Surgically,an alternative bilioenteric bypass was performed by means of an ileal loop interposition between the bile duct and the jejunum. RESULT:The recovery of the patient was uneventful and his bilirubin levels normalized after one *** patient was then referred for systemic chemotherapy. CONCLUSIONS:This alternative biliary bypass can be safely and easily performed,and may be a good alternative for patients already referred for surgery because of a better life expectancy and when the jejunum is not an alternative.

screening and identification of mimotopes of the major shrimp allergen tropomyosin using one-bead-one- compound peptide libraries

The one-bead-one-compound （OBOC） combinatorial peptide library is a powerful tool to identify ligand and receptor interactions. Here, we applied the OBOC library technology to identify mimotopes specific to the immunoglobulin E （IgE） epitopes of the major shellfish allergen tropomyosin. OBOC peptide libraries with 8-12 amino acid residues were screened with serum samples from patients with shellfish allergy for IgE mimotopes of tropomyosin. Twenty-five mimotopes were identified from the screening and their binding reactivity to tropomyosin-specific IgE was confirmed by peptide ELISA. These mimotopes could be divided into seven clusters based on sequence homology, and epitope mapping by EpiSearch of the clustered mimotopes was performed to characterize and confirm the validity of mimotopes. Five out of six of the predicted epitopes were found to overlap with previously identified epitopes of tropomyosin. To further confirm the mimicry potential of mimotopes, BALB/c mice were immunized with mimotopes conjugated to keyhole limpet hemocyanin and assayed for their capacity to induce tropomyosin-specific antibodies. BALB/c mice that received mimotope immunization were found to have an elevated level of tropomyosin-specific immunoglobulin G, but not mice that received an irrelevant mimotope. This study pioneers the successful application of the OBOC libraries using whole sera to screen and identify multiple shrimp allergen mimotopes and validates their mimicry potential using in vitro, in vivo, and in silico methods.

颈动脉体对化学信号的换能作用

颈动脉体可以将低氧和血液中其它刺激信号(可能包括低血糖)转换成不同强度的传入神经放电,沿心肺和神经内分泌反射的传入途径进入中枢,形成反射环路。低氧可抑制颈动脉体Ⅰ型细胞中的多种K+通道,这种作用可能有种属差异; K+通道的抑制使膜电位去极化,启动电压依赖性Ca2+内流,最后导致神经分泌和传入放电。离子通道埘低氧的反应可能是通过间接途径发生的,因此近期的工作集中在研究颈动脉体Ⅰ型细胞中在低氧感受中起关键作用的其它蛋白质。虽然有人认为来源于线粒体和／或NADPH的活性氧(reactive oxygen species,ROS)起一定作用,但是它们在颈动脉体中转导低氧信号的证据还不足。目前正在对另外两种假设进行检验。第一种假设是血红素加氧酶2(haemoxygenase 2,HO-2)通过信号分子CO控制特殊K+通道的活动,而CO的生成量与氧分压高低有关。第二种假设是认为细胞能量感受器腺苷酸活化蛋白激酶(AMP- activated protein kinase,AMPK)起作用;低氧时AMP／ATP比值升高,激活AMPK,从而抑制Ⅰ型细胞的K+通道,传入放电增加。颈动脉体的细胞上具有丰富的对氧敏感的K+通道,低氧感受这个重要的细胞活动可以通过多条途径进行,在总反应中每种蛋白质也可能起不同的作用,例如不同蛋白质对氧的亲合力不同等。关于颈动脉体感受低血糖的机制尚不清楚,但最近有证据提示,它并非由K+通道关闭引起的,因此感受低血糖的机制和感受低氧的机制是不同的。
