Present Analysis of Off-indication Drug Use of Drugs for High Altitude Pulmonary Edema / 中国药房

OBJECTIVE:To analyze the situation of off-indication drug use of drugs for high altitude pulmonary edema (HAPE),and to provide reference for promoting rational drug use in medical institutions of plateau area and establishing relevant management process. METHODS:By taking"HAPE""treatment""Altitude illness""Treatment"as keywords,retrieving from CNKI,PubMed,Embase database during build up to Sept. 2017,drugs for HAPE were screened and extracted after reading the literatures. Drug package inserts of listed preparations were compared,summarized and analyzed. RESULTS:Drugs for HAPE in literatures were screened,and 16 kinds of drugs were summarized finally as nifedipine,sildenafil,tadalafil,aminophylline,etc. Indication of HAPE was not found in drug package inserts of those listed preparations. CONCLUSIONS:At present,there is a universal phenomenon of off-indication drug use of drugs for HAPE,and it is imminent to regulate the management of off-label drug use in the hospital. It is suggested to improve the off-label drug use management flow of drugs for HAPE so as to promote rational drug use.

Normal light and fluorescence microscopy for authentication of Delphinii Brunoniani Herba of Tibet / 药学学报

Dried herb of Delphinium brunonianum Royle (Ranunculaceae) has long been used under the herbal name "Xiaguobei" (Delphinii Brunoniani Herba) in traditional Tibetan medicine and prescribed for the treatment of influenza, itchy skin rash and snake bites. In order to find a useful and convenient method for the identification of microscopic features, the technique of fluorescence microscopy was applied to authenticate "Xiaguobei" of Tibet. The transverse sections of stem and leaf, as well as the powder of "Xiaguobei" were observed to seek for typical microscopic features by normal light and fluorescence microscopy. A style-like, single-cell glandular hair containing yellow secretions on the leaf, young stem and sepal of "Xiaguobei" was found. Under the fluorescence microscope, the xylem and pericycle fiber group emitted significant fluorescence. This work indicated that fluorescence microscopy could be an useful additional method for the authentication work. Without the traditional dyeing methods, the main microscopic features could be easily found by fluorescence microscopy. The results provided reliable references for the authentication of "Xiaguobei".
