Role of Akkermansia muciniphila in the development of nonalcoholic fatty liver disease: current knowledge

《医学前沿(英文)》 2022年 第16卷 第5期   页码 667-685 doi: 10.1007/s11684-022-0960-z

摘要: Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome and a common cause of liver cirrhosis and cancer. Akkermansia muciniphila (A. muciniphila) is a next-generation probiotic that has been reported to improve metabolic disorders. Emerging evidence indicates the therapeutic potential of A. muciniphila for NAFLD, especially in the inflammatory stage, nonalcoholic steatohepatitis. Here, the current knowledge on the role of A. muciniphila in the progression of NAFLD was summarized. A. muciniphila abundancy is decreased in animals and humans with NAFLD. The recovery of A. muciniphila presented benefits in preventing hepatic fat accumulation and inflammation in NAFLD. The details of how microbes regulate hepatic immunity and lipid accumulation in NAFLD were further discussed. The modulation mechanisms by which A. muciniphila acts to improve hepatic inflammation are mainly attributed to the alleviation of inflammatory cytokines and LPS signals and the downregulation of microbiota-related innate immune cells (such as macrophages). This review provides insights into the roles of A. muciniphila in NAFLD, thereby providing a blueprint to facilitate clinical therapeutic applications.

Human microbiome and prostate cancer development: current insights into the prevention and treatment

Solmaz Ohadian Moghadam, Seyed Ali Momeni

《医学前沿(英文)》 2021年 第15卷 第1期   页码 11-32 doi: 10.1007/s11684-019-0731-7

摘要: The huge communities of microorganisms that symbiotically colonize humans are recognized as significant players in health and disease. The human microbiome may influence prostate cancer development. To date, several studies have focused on the effect of prostate infections as well as the composition of the human microbiome in relation to prostate cancer risk. Current studies suggest that the microbiota of men with prostate cancer significantly differs from that of healthy men, demonstrating that certain bacteria could be associated with cancer development as well as altered responses to treatment. In healthy individuals, the microbiome plays a crucial role in the maintenance of homeostasis of body metabolism. Dysbiosis may contribute to the emergence of health problems, including malignancy through affecting systemic immune responses and creating systemic inflammation, and changing serum hormone levels. In this review, we discuss recent data about how the microbes colonizing different parts of the human body including urinary tract, gastrointestinal tract, oral cavity, and skin might affect the risk of developing prostate cancer. Furthermore, we discuss strategies to target the microbiome for risk assessment, prevention, and treatment of prostate cancer.

《医学前沿(英文)》 2010年 第4卷 第3期   页码 271-274 doi: 10.1007/s11684-010-0100-z

摘要: Prenatal screening and diagnosis are major methods for control of birth defects, which is a very important problem in China. Here, we review current situation and development of prenatal screening and diagnosis in mainland China, including prenatal screening and prenatal diagnosis of fetal chromosome abnormalities, non-invasive prenatal diagnostic techniques and prenatal diagnosis of monogenic diseases, polygenic disease and congenital metabolic diseases. We also discuss epidemiology of birth defects and genetic diseases in China and related ethical issues of prenatal diagnosis.

Current research, key performances and future development of search and rescue robots

LIU Jinguo, WANG Yuechao, LI Bin, MA Shugen

《机械工程前沿(英文)》 2007年 第2卷 第4期   页码 404-416 doi: 10.1007/s11465-007-0070-2

摘要: Frequent natural disasters and man-made catastrophes have threatened the safety of citizens and have attracted much more attention. The rescue mission under disaster environment is very complicated and dangerous for a rescue team. Search and rescue (SAR) robots can not only improve the efficiency of rescue operations but also reduce the casualty of rescuers. Robots can help rescue teams and even replace rescuers to perform dangerous missions. Search and rescue robots will play a more and more important role in the rescue operations. A survey of the research status of search and rescue robots in Japan, USA, China and other countries has been provided. According to current research, experiences and the lessons learned from applications, the five key performances of a search and rescue robot are survivability, mobility, sensing, communicability and operability. Multi-technique fusion and multi-agent intelligent network are considered to be requirements for the future development of the search and rescue robot. Disaster prevention, disaster reduction and disaster rescue are the important parts of national public safety. They are also crucial for the safety of citizens and their estates. Search and rescue robotic technique is an urgent needed, strategic and core technique for national development. It will be important and strategic for national economy and safety.

Consolidated standards of reporting trials (CONSORT) for traditional Chinese medicine: current situationand future development

Zhaoxiang Bian, Baoyan Liu, David Moher, Taixiang Wu, Youping Li, Hongcai Shang, Chungwah Cheng

《医学前沿(英文)》 2011年 第5卷 第2期   页码 171-177 doi: 10.1007/s11684-011-0132-z

摘要: The reporting standards for randomized controlled trials were first published in 1996 by a group of scientists under the name “CONSORT,” which means consolidated standards of reporting trials. Revisions followed in 2001 and 2010. A draft of the CONSORT for traditional Chinese medicine (TCM) was published in both Chinese and English in 2007. After publication of the draft, comments were solicited from the medical community. Some papers did raise concerns about which items should be included in the CONSORT for TCM such as the rationale of the trial design, intervention, outcome assessment, and adverse events. We have now reached the next step which is the finalization of the CONSORT for TCM. Three tasks remain. First, the major changes in CONSORT statement 2010 should be integrated into the CONSORT for TCM. Second, Chinese drugs from minerals and animals should be included in the guidelines. Finally, agreement must be reached among the working groups. Once the draft is finalized, wide dissemination and co-publication will be considered.
