High-content screening in studies of toxicology and its application in drug-induced hepatotoxicity / 中国药理学与毒理学杂志

Drug-induced liver injury(DILI) is one of the major causes of termination of drug development.The establishment of a high-throughput test system to predict potential clinical hepatotoxicity is a valuable approach in the pharmaceutical industry.The high-content imaging-based in vitro assays allow simultaneous detection of cellular multiple parameters in the system.The real-time monitoring of multiple signaling pathways can shed light on many mechanisms of cell injury,with high sensitivity and specificity.Many types of liver cell models have been applied to high-content screening(HCS) so far.This paper introduceds the HCS technology and reviews the data of hepatotoxicity obtained from HCS technology in recent years.At the same time,we discuss the application of this technology in exploring the mechanism of hepatotoxicity and the potential of HCS technology in studying DILI and mechanisms.

WBC Increasing Medicine Usage Analysis in Cancer Patients in a Hospital / 中国药师

Objective:To investigate the application of leukogenic medicine in cancer patients and standardize the use of WBC increasing medicine in a hospital. Methods:A retrospective analysis of 579 patient records from January 2014 to December in a hospital diagnosed as malignant tumor and issued WBC increasing medicine . The kinds of drugs,timing of administration, dosage,frequency of administration,the use of medication,drug combination and the choice of solvent were analysed by collecting the patients’ essential information, chemotherapy, myelosuppression etc. Results: The l white blood drugs mainly oral preparations;There were 414 rational drug use medication orders,accounting for 71. 50 percent;irrational drug use medical record 165,accounting for 28. 50% . The dosage and duration of treatment in line with requirements,and unreasonable cases mainly suitable varieties and timing of administration based,42. 42% and 27. 88% ,respectively;followed by repeated dosing and combination therapy is not suitable,13. 33% 1and 2. 73,respectively;a lower incidence of solvent choice unsuitable,is 3. 64% . Conclusion:The use of WBC increasing medicine need to be standardized in cancer patients in the hospital. Clinicians need to strengthen studying the knowledge of the application of WBC increasing medicine and use WBC increasing medicine rationally.
