Biliary tract cancer, or cholangiocarcinoma, comprises a heterogeneous group of malignant tumors that can emerge at any part of the biliary tree. This group is the second most common type of primary liver cancer. Diagnosis is usually based on symptoms, which may be heterogeneous, and nonspecific biomarkers in serum and biopsy specimens, as well as on imaging techniques. Endoscopy-based diagnosis is essential, since it enables biopsy specimens to be taken. In addition, it can help with locoregional staging of distal tumors. Endoscopic retrograde cholangiopancreatography is a key technique for the evaluation and treatment of malignant biliary tumors. Correct staging of cholangiocarcinoma is essential in order to be able to determine the degree of resectability and assess the results of treatment. The tumor is staged based on the TNM classification of the American Joint Committee on Cancer. The approach will depend on the classification of the tumor. Thus, some patients with early-stage disease could benefit from surgery;complete surgical resection is the cornerstone of cure. However, only a minority of patients are diagnosed in the early stages and are suitable candidates for resection. In the subset of patients diagnosed with locally advanced or metastatic disease, chemotherapy has been used to improve outcome and to delay tumor progression. The approach to biliary tract tumors should be multidisciplinary, involving experienced endoscopists, oncologists, radiologists, and surgeons.

＜正＞ This study investigates whether endogenous male sex hormones affect the participation of thromboxane （TXA2） in the acetylcholine （Ach）-induced response in rat aorta. For this purpose, aorta from control and orchidectomized male Sprague Dawley rats were used to analyze: （1） vascular response to Ach;（2） vascular response to the TXA2 mimetic U-46619 and, （3） the basal and Ach stimulated production of TXB2, the stable TXA2 metabolite. The Ach-induced relaxation was unaltered by the TXA2 synthesis inhibitor, furegrelate, in arteries from control rats while was increased in aortas from orchidectomized rats. In intact vessels, the concentration dependent contraction induced by U-46619 was similar in arteries from both rat groups. The basal and Ach-stimulated TXB2 release was increased in arteries from orchidectomized animals. These results show that TXA2 production is increased in aortas from orchidectomized rats compared to their controls, and that this prostanoid is functionally involved in the vasodilator response to Ach only in arteries from orchidectomized rats.

作者： Carlos Encinas-ferrer Francisco javier ValderreY-Villar Clemente Hernandez-Rodriguez Antonio Uson-Sardana Tecnologico de Monterrey Campus Leon Leon Mexico Tecnologico de Monterrey Campus Guadalajara Guadalajara Mexico Universidad de Zaragoza Zaragoza Espana

In this paper we analyze the characteristics of the so-called rare earth elements （REEs） and its industrial applications. We present the policy, or lack thereof, in the countries in the Pacific Rim for its mining and commerce, and the current and future weight that rare earth minerals will have in international trade. The technological revolution experienced over the last 25 years, has brought the REEs to the public＇s attention for being instrumental in obtaining catalysts, lasers and optical fiber, luminescent substances and LEDs, superconductors, permanent magnets, batteries and ultra-capacitors. China＇s leading position as the supplier of these minerals worldwide, and its recent export restriction policy for domestic industrial activities have driven up international prices. Price increase for REEs is leading to the need for both recycling and its replacement. It has also led other countries in the Asia Pacific Rim to prospect new potential sites on their own territories, or even to restart operations in deposits that had been previously abandoned. Those strategies will likely gain greater importance as environmental pollution problems associated with the exploitation, processing, and recovery of REEs increase.

Endoscopic evaluation of immunotherapy-induced gastrointestinal toxicity

Immunotherapy is any treatment aimed at boosting or enhancing the immune system. It includes a wide range of options, from vaccines to treatment for conditions such as allergy and cancer. In the case of cancer, unlike other available treatments, immunotherapy is not aimed at destroying the tumor cells but at stimulating the patient's immune system so that it attacks the tumor. In cancer,immunotherapy provides a series of advantages. Nevertheless, immunotherapy administered for treatment of cancer is associated with immune-mediated enterocolitis. Colitis mediated by monoclonal anti-cytotoxic T lymphocyte–associated antigen 4 and to programmed cell death protein 1 and its ligand PDL1 shares characteristics with chronic inflammatory bowel disease(IBD), and similar findings have been reported for both the endoscopy images and the segment involved. The most frequent lesions on endoscopy are ulcer and erythema, and the most frequently affected site is the sigmoid colon. A segmental pattern has been reported to be slightly more frequent than a continuous *** addition, upper gastrointestinal lesions have been reported in up to half of patients, with the most frequent findings being gastritis and erosive *** is the case in IBD, systemic corticosteroids and immunosuppressive treatment(anti-TNF agents) are the approaches used in patients with a more unfavorable progression.

Screening for colorectal cancer in patients with inflammatory bowel disease. Should we already perform chromoendoscopy in all our patients?

引用

World Journal of Gastrointestinal Endoscopy 2018年第11期10卷 322-325页

作者： Jose María Huguet Patrícia Suárez Luis ferrer-Barceló Isabel Iranzo javier Sempere Digestive Disease Department Hospital General Universitario de Valencia

Patients with inflammatory bowel disease(commonly known as IBD) have a greater risk of colorectal cancer than the general population. Therefore, they are included in special programs for screening and followup. Chromoendoscopy, which has a high diagnostic yield in the detection of neoplasia, is generally the recommended endoscopy technique. However, this procedure does have some disadvantages(long examination time, need for optimal bowel preparation, specialist training), which increase its cost. How then can we overcome these barriers? First, it is necessary to educate hospital managers and directors of the advantages of chromoendoscopy in patients with IBD. Second, at least one endoscopist per center should be a specialist in the technique. Third, we should train nursing staff in the preparation of the dye. Finally, each examination should be given the time it needs. Even though clinical practice guidelines do not yet recommend the use of virtual imaging techniques such as narrow band imaging, a recent study reported no differences between the two approaches for the detection of tumors. Therefore, we believe that all patients should undergo chromoendoscopy. In the future, centers without access to dyes or where other barriers exist should at least perform narrow band imaging.

Endoscopic recommendations for colorectal cancer screening and surveillance in patients with inflammatory bowel disease:Review of general recommendations

引用

World Journal of Gastrointestinal Endoscopy 2017年第6期9卷 255-262页

作者： Jose María Huguet Patricia Suárez Luis ferrer-Barceló Lucía Ruiz Ana Monzó Ana Belén Durá javier Sempere Digestive Disease Department General University Hospital of Valencia46014 ValenciaSpain

Screening for colorectal cancer(CRC) in patients with inflammatory bowel disease(IBD) is recommended by all scientific societies. However, there are differences in the recommendations they make regarding screening and surveillance. We address a series of questions that come up in the daily clinical practice of a physician. The first two questions that are raised are:(1) Who should be offered screening for CRC? and(2) When should the first colonoscopy be performed? The next step is to decide who should undergo endoscopic surveillance and at what intervals they should be performed. Chromoendoscopy is emerging as the recommended endoscopic technique for screening and surveillance. The terminology for describing lesions detected with endoscopy is also changing. The management of visible lesions or non-visible dysplasia is also a motive for the review. We end the review by addressing the followup for endoscopically resected lesions. These questions often cannot be answered easily due to the varying degrees of evidence available; therefore, we have made some general recommendations based on those made by the various guidelines and consensuses. The first screening colonoscopy should be offered 8 years after a IBD diagnosis and we recommend that patients be stratified according to the individual risk for each for endoscopic surveillance intervals.
