2Topological and evolutional relationships between HCV core protein and hepatic lipid vesicles: Studies in vitro and in conditionally transgenic mice显示文摘AIM: To investigate a specific association between hepatic steatosis and hepatitis C virus (HCV) core. METHODS: HeLa cells and primary mouse hepatocytes were transfected with HCV core plasmid, and conditional transgenics in which hepatic over-expression of HCV core is regulated by the tetracycline-off system, were developed. The expression of the HCV core was assessed over one to six months after withdrawal of doxycycline (dox) by immunohistochemistry (IHC) and Western blotting and by sequential liver biopsy. Hepatic steatosis was evaluated using oil red stain. 8-hydroxydeoxyguanosine (8-OHdG) stains and caspase levels were conducted to clarify hepatic oxidative stress and apoptosis rate. Serum aminotransferase was checked. RESULTS: The transfected hepatocytes had globular cores under the lipid vesicles. In transgenic mice on control diet, core expression was robust, localized to the cytoplasmic vesicle membrane and strongly associatedwith microvesicular steatosis, which was gradually replaced by macrovesicular steatosis. However, both steatosis and core positive hepatocytes diminished with time. Increases in aminotransferase, caspase and 8-OHdG were associated with peak core expression. CONCLUSION: The core protein was readily detected and morphologically associated with steatosis in individual hepatocytes both in vitro and in vivo. In vivo, oxidative stress caused by the core potentially reduced the number of core positive hepatocytes and in parallel the level of steatosis. To our knowledge, this is the f irst animal model that directly shows topological relationship between HCV core and hepatic lipid vesicles.Ming-Ling Chang Jeng-Chang Chen Chau-Ting Yeh I-Shyan Sheen Dar-In Tai Ming-Yu Chang Cheng-Tang Chiu Deng-Yn Lin D Montgomery Bissell 2007World Journal of Gastroenterology2007,13,25:4
3精神病病人和服用精神类药物病人接受和长期接受阿片类药物治疗:国家级商业保险索赔研究显示文摘越来越多的证据表明,美国的阿片类处方正遵循一种'逆向选择'模式,这种模式使得接受阿片类药物长期治疗的病人更可能处于阿片类药物不良反应的最大风险中,特别是那些物质使用障碍(SUD)和其他精神病病人。本研究调查了10311961位填写阿片类处方病人的医疗保险索赔情况,特别比较了患精神病及行为异常(比如阿片类和非阿片类SUD、自杀倾向或自残行为、机动车事故、抑郁症、焦虑症和睡眠障碍)和未患精神病及无行为异常病人、服用精神类药品(如抗抑郁药、苯二氮?类药物、安眠药、镇定剂、抗精神病药品和用于治疗SUD、烟草戒断、多动症的药物)和未服用精神类药品病人之间接受阿片类药物治疗的区别。相对于对照组,有精神病或服用精神类药品的病人随后须接受阿片类药物治疗的风险稍高,特别是,接受阿片类药物长期治疗的风险更高。利用校正型Cox回归模型可知,多动症病人接受阿片类药物长期治疗的风险是无多动症病人的1.5倍(危险比(HR)=1.53,95%可信区间:1.48-1.58),非阿片类SUD病人风险约是无此疾患病人的3倍(危险比(HR)=3.15,95%可信区间:3.06-3.24),阿片类使用障碍病人的风险是无此疾患病人的9倍(危险比(HR)=8.70,95%可信区间:8.20-9.24)。总而言之,本研究发现有精神疾病状态的商业保险病人更可能接受阿片类药物治疗。未来关于阿片类药物行为结局的研究需考虑病人的先存精神疾病状况。Patrick D Quinn Kwan Hur Zheng Chang 王艳娉 杨俊龙 张小梅 2017中国疼痛医学杂志2017,23,9:3

5Medical training fails to prepare providers to care for patients with chronic hepatitis B infection显示文摘AIM: To investigate physicians' knowledge including chronic hepatitis B(CHB) diagnosis, screening, and management in various stages of their training.METHODS: A voluntary 20-question survey was administered in Santa Clara County, CA where Asian and Pacific Islanders(API) account for a third of the population. Among the 219 physician participants,there were 63 interns, 60 second-year residents, 26 chief residents and 70 attending physicians. The survey asked questions regarding respondents' demographics,general hepatitis B virus knowledge questions(i.e.,transmission, prevalence, diagnostic testing, prevention,and treatment options), as well as, self-reported practice behavior and confidence in knowledge.RESULTS: Knowledge about screening and managing patients with CHB was poor: only 24% identified the correct tests to screen for CHB, 13% knew the next steps for patients testing positive for CHB, 18% knew the high prevalence rate among API, and 31% knew how to screen for liver cancer. Wald chi-square analysis determined the effect of training level on knowledge; in all cases except for knowledge of liver cancer screening(p = 0.0032), knowledge did not significantly increase with length in residency training or completion of residency.CONCLUSION: Even in a high-risk region, both medical school and residency training have not adequatelyprepared physicians in the screening and management of CHB.Stephanie D Chao Bing-Mei Wang Ellen T Chang Li Ma Samuel K So 2015World Journal of Gastroenterology2015,21,22:2
6Intravascular large B-cell lymphoma presenting with altered mental status: A case report显示文摘BACKGROUND Intravascular large B-cell lymphoma(IVLBCL)is a rare and aggressive subtype of non-Hodgkin lymphoma with a varied presentation and no pathognomonic findings.Early diagnosis is critical to altering the disease course as early treatment with chemoimmunotherapy is required to prevent a rapidly fatal outcome.Strategies including improved awareness of this clinical entity through publication of cases with unique presentations are essential to prompt consideration of IVLBCL early in the disease workup.Here,we present a case of IVLBCL presenting with altered mental status and systemic organ dysfunction.CASE SUMMARY A 61-year-old male patient presented with flu-like symptoms and a high fever.He experienced rapid clinical deterioration with liver,kidney failure,and shock despite rapid antibiotic administration and supportive care.A broad infectious workup was negative.Intracranial imaging revealed nonspecific changes to the corpus callosum suspicious for vasculitis.Renal biopsy was non-diagnostic.After further progression of his symptoms,the family elected to withdraw care and the patient died shortly thereafter.Post-mortem analysis revealed clear multi-organ involvement by IVLBCL,prompting re-examination of the ante-mortem renal biopsy that also identified IVLBCL involvement.CONCLUSION IVLBCL is a rare disease.Communication with specialties and early biopsy is critical to establishing the diagnosis and initiating therapy.Christopher Robert D’Angelo Kimberly Ku Jessica Gulliver Julie Chang 2019World Journal of Clinical Oncology2019,10,12:2

8Panda X-III: Searching for neutrinoless double beta decay with high pressure ^(136)Xe gas time projection chambers显示文摘Searching for the neutrinoless double beta decay(NLDBD)is now regarded as the topmost promising technique to explore the nature of neutrinos after the discovery of neutrino masses in oscillation experiments.Panda X-III(particle and astrophysical xenon experiment III)will search for the NLDBD of136Xe at the China Jin Ping Underground Laboratory(CJPL).In the first phase of the experiment,a high pressure gas Time Projection Chamber(TPC)will contain 200 kg,90%136Xe enriched gas operated at10 bar.Fine pitch micro-pattern gas detector(Microbulk Micromegas)will be used at both ends of the TPC for the charge readout with a cathode in the middle.Charge signals can be used to reconstruct the electron tracks of the NLDBD events and provide good energy and spatial resolution.The detector will be immersed in a large water tank to ensure~5 m of water shielding in all directions.The second phase,a ton-scale experiment,will consist of five TPCs in the same water tank,with improved energy resolution and better control over backgrounds.Xun Chen Chang Bo Fu Javier Galan Karl Giboni Franco Giuliani Ling Hui Gu Ke Han Xiang Dong Ji Heng Lin Jiang Lai Liu Kai Xiang Ni Hiroki Kusano Xiang Xiang Ren Shao Bo Wang Yong Yang Dan Zhang Tao Zhang Li Zhao Xiang Ming Sun Shou Yang Hu Si Yu Jian Xing Long Li Xiao Mei Li Hao Liang Huan Qiao Zhang Ming Rui Zhao Jing Zhou Ya Jun Mao Hao Qiao Si Guang Wang Ying Yuan Meng Wang Amir N.Khan Neill Raper Jian Tang Wei Wang Jia Ning Dong Chang Qing Feng Cheng Li Jian Bei Liu Shu Bin Liu Xiao Lian Wang Dan Yang Zhu Juan F.Castel Susana Cebri'an Theopisti Dafni Javier G.Garza Igor G.Irastorza Francisco J.Iguaz Gloria Luz ′on Hector Mirallas Stephan Aune Eric Berthoumieux Yann Bedfer Denis Calvet Nicole d'Hose Alain Delbart Maria Diakaki Esther Ferrer-Ribas Andrea Ferrero Fabienne Kunne Damien Neyret Thomas Papaevangelou Franck Sabatie Maxence Vanderbroucke AnDi Tan Wick Haxton Yuan Mei Chinorat Kobdaj Yu-Peng Yan 2017Science China(Physics,Mechanics & Astronomy)2017,60,6:2
