The tuning system plays a very important role when a superconducting cavity is in operation. It cooperates with other control loops to adjust the cavity frequency with high precision, reduce the reflection power, guarantee the stability of beam, and ensure the safety of the superconducting cavity. This paper focuses mainly on the tuning system working principle, the working state and problems that Beijing Electron Positron Collider （BEPC ｜I ） has encountered during operation.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

Cholangiocarcinoma refers to malignant tumors that develop in epithelial lining of biliary system, and it is divided into two categories according to tumor location, intrahepatic cholangiocarcinoma （ICC） and extrahepatic cholangiocarcinoma （ECC）. ICC occurs from the epithelial cells of the intrahepatic bile duct, its branches and interlobular biliary tree; and ECC is divided into hilar cholangiocarcinoma and distal cholangiocarcinoma by the circumscription at the confluence of cystic duct and the common hepatic duct.

自我国实施药品注册管理以来,中药注册分类在满足公众健康需求、指导中医药科研成果转化及传承创新上发挥了重要作用。三十余年间,中药新药创制均基于"一方一药"的注册转化模式。该模式借鉴了现代药品的研发注册制度,虽然贴近中医临床中的"守方守法"用药,但难以体现中医辨证求因的序贯治疗思想和多措并举的综合治疗手段。2017年,中共中央办公厅、国务院办公厅《关于深化审评审批制度改革鼓励药品医疗器械创新的意见》指出要"建立完善符合中药特点的注册管理制度和技术评价体系,处理好保持中药传统优势与现代药品研发要求的关系"。因此,现阶段中药研发的技术要求和注册制度需要在遵循中医药发展规律、符合中医药理论特点基础上进一步解放思路,更多地基于临床思维去思考设计。该文结合我国中药注册监管情形和现代药物研发模式转变,分析当前"一方一药"研发注册模式的局限和不足,并尝试提出一种更加切合中医临证思维、还原中医临床实景的"系列方药"同步转化的研发注册新模式,希望有助于中医药产业的传承创新和高质量发展。
