Background: Biliary mucinous cystic neoplasms(BMCNs) are rare hepatobiliary cystic tumors, which can be divided into noninvasive and invasive types. This study aimed to investigate the diagnosis, treatment, and prognosis of BMCNs in a large single center. Methods: We analyzed 49 patients with BMCNs confirmed by postoperative pathology at the First Afflliated Hospital, Zhejiang University school of Medicine between January 2007 and December 2021. Results: Among the 49 patients, 37 were female(75.5%), and the average age was 57.04 years. Common symptoms included abdominal discomfort, jaundice and fever, while 22 patients(44.9%) had no symptoms. Serum carbohydrate antigen(CA) 19-9 and CA125 concentrations were elevated in 34.8% and 19.6% of patients, respectively. Forty-eight patients had tumors in the intrahepatic bile ducts and only one had a tumor in the extrahepatic bile duct. Forty-eight patients with noninvasive intrahepatic BMCNs were further analyzed in terms of pathological features: 34(70.8%) had low-grade intraepithelial neoplasms(LGINs), and 14(29.2%) had high-grade intraepithelial neoplasms(HGINs). The potential immunohistochemical markers of BMCNs were cytokeratin(CK) 19, CK7, estrogen receptor and progesterone receptor. Follow-up data for 37 patients with intrahepatic BMCNs were obtained. The median overall survival(OS) of BMCNs was not reached. The longest survival time was 137 *** 5-and 10-year OS rates were 100% and 85.4%, respectively. The 5-and 10-year recurrence-free survival(RFS) rates were 93.9% and 80.2%, respectively. Conclusions: BMCNs are rare cystic neoplasms that commonly occur in middle-aged females. BMCNs can only be diagnosed and classified by postoperative pathology, as there are no specific clinical presentations, serological indicators or imaging modalities for preoperative diagnosis. Complete surgical resection is necessary for BMCNs, and the postoperative prognosis is favorable.

IEEE/CAA Journal of Automatica Sinica 2024年第1期11卷 252-254页

作者： Chenliang Liu Yalin Wang Chunhua Yang Weihua Gui the school of Automation Central South UniversityChangsha 410083China IEEE

Dear Editor, This letter proposes a multimodal data-driven reinforcement learning-based method for operational decision-making in industrial processes. Due to the frequent fluctuations of feedstock properties and operating conditions in the industrial processes, existing data-driven methods cannot effectively adjust the operational variables. In addition, multimodal data such as images, audio.

Antioxidants Enzymes Activities and NO Levels in Hemodialysis and Continuous Ambulatory Peritoneal Dialysis—A Comparative Study

引用

Journal of Biosciences and Medicines 2024年第2期12卷 50-59页

作者： Natalia Cristina Aparecida Ribeiro e Ribeiro Anderson Martins Tavares Jaslana Hainfellner da Silva João Paulo Lima Daher Salim Kanaan Luciene de Carvalho Cardoso-Weide Laboratory of Neuroplasticity Neurobiology Department Biology Institute Federal Fluminense University Rio de Janeiro Brazil postgraduate Program in Medical Sciences School of Medicine Federal Fluminense University Rio de Janeiro Brazil school of Biology UNIVERSO—Salgado de Oliveira University Rio de Janeiro Brazil Department of Pathology Faculty of Medicine Federal Fluminense University Rio de Janeiro Brazil

It consists of a retrospective study with twenty-two individuals diagnosed with DRC: fourteen HD and eight CAPD, followed up in the dialysis center of Antonio Pedro University Hospital (HUAP) of Fluminense Federal University (UFF), between 2015 and 2017. Fifteen healthy control (HC) subjects were included, without diagnosed CKD. Patients with HIV positive, hepatitis A, B, and C, pregnant, cancer, smokers, alcoholics and those exposed to X-rays in the last 3 months, were excluded. Objectives: As oxidative stress and endothelial dysfunction may be linked to the higher prevalence of CVD in CKD patients, we measured the activities of the antioxidants enzymes: SOD and GPx and total NO levels in the plasma and serum of end-stage CKD patients undergoing dialysis therapy, comparing with the HC group. Methods: Quantification of NO levels was performed by fluorometric kit, while activities of SOD and GPx were determined using kinetic methods. Results: We found higher plasma SOD activity in HD (8.58 U/ml) and CAPD (10.14 U/ml), compared to C (3.73 U/ml) group, while GPx activity was decreased in HD (115.38 nmol/h/ml) and CAPD (122.76 nmol/h/ml) groups compared to HC group (275.83 nmol/h/ml). Total serum NO concentration was decreased in HD (14.09 pmol/μl) and CAPD (10.26 pmol/μl), compared to non-CKD patients (49.65 pmol/μl). Conclusion: Decreased total serum NO and GPx activities may lead to endothelial dysfunction and consequently a higher prevalence of CVD in CKD patients.
