《中国中医古籍总目》误收西医妇科学著作7则

《中国中医古籍总目》作为迄今为止收载中医书籍最为全面的目录书,其中收载的民国妇科学著作,对于中医妇科学的研究有着重要作用。就其著录的妇科书籍范围而言,应该仅限于中医妇科学著作。然而,种种原因导致其误收了部分西医妇科学著作。文章指出了《中国中医古籍总目》误收的7部西医妇科学著作,并期望再版时此问题能够改正。

青岛流亭国际机场蝇类名录

目的了解青岛流亭国际机场口岸蝇类本底情况,为制定有效的控制措施及监测医学媒介生物提供依据。方法2006年6月至2008年5月对青岛流亭国际机场口岸采用诱蝇笼捕集法,并不定期配合采用人工网捕法进行蝇类及其孳生地的调查。结果共捕获蝇类46726只,经分类鉴定隶属7科47属98种,其中30种为山东省新记录。结论本次调查全面掌握了青岛流亭国际机场口岸蝇类的种类组成。对今后该口岸蝇类控制和发现蝇类种类新记录具有指导意义。     

Aristolochic acids exposure was not the main cause of liver tumorigenesis in adulthood

Aristolochic acids (AAs) have long been considered as a potent carcinogen due to its nephrotoxicity. Aristolochic acid I (AAI) reacts with DNA to form covalent aristolactam (AL)–DNA adducts, leading to subsequent A to T transversion mutation, commonly referred as AA mutational signature. Previous research inferred that AAs were widely implicated in liver cancer throughout Asia. In this study, we explored whether AAs exposure was the main cause of liver cancer in the context of HBV infection in mainland China. Totally 1256 liver cancer samples were randomly retrieved from 3 medical centers and a refined bioanalytical method was used to detect AAI–DNA adducts. 5.10% of these samples could be identified as AAI positive exposure. Whole genome sequencing suggested 8.41% of 107 liver cancer patients exhibited the dominant AA mutational signature, indicating a relatively low overall AAI exposure rate. In animal models, long-term administration of AAI barely increased liver tumorigenesis in adult mice, opposite from its tumor-inducing role when subjected to infant mice. Furthermore, AAI induced dose-dependent accumulation of AA–DNA adduct in target organs in adult mice, with the most detected in kidney instead of liver. Taken together, our data indicate that AA exposure was not the major threat of liver cancer in adulthood.
