Objective:To analyze the prophylactic use of antibiotics during the perioperative period of typeⅠincision operation in a cancer hospital in order to promote the safe, effective and rational use of antibiotics. Methods:The rationality of 480 cases of typeⅠincision operation from January to December in 2013 and from January to December in 2014 was evaluated respectively, and the analy-sis and comparison were performed on the prophylactic use of antibiotics. Results: Through the pharmaceutical intervention including the special evaluation carried out by clinical pharmacists, the use of antibiotics gradually reached the rational level. Conclusion: The participation of clinical pharmacists in the use management of antibiotics in typeⅠincision operation can improve the rationality of the drugs used in clinic.

Huntington's disease (HD) is a deadly neurodegenerative disease with abnormal expansion of CAG repeats in the huntingtin gene. Mutant Huntingtin protein (mHTT) forms abnormal aggregates and intranuclear inclusions in specific neurons, resulting in cell death. Here, we tested the ability of a natural heat-shock protein 90 inhibitor, Gedunin, to degrade transfected mHTT in Neuro-2a cells and endogenous mHTT aggregates and intranuclear inclusions in both fibroblasts from HD patients and neurons derived from induced pluripotent stem cells from patients. Our data showed that Gedunin treatment degraded transfected mHTT in Neuro-2a cells, endogenous mHTT aggregates and intranuclear inclusions in fibroblasts from HD patients, and in neurons derived from induced pluripotent stem cells from patients in a dose- and time-dependent manner, and its activity depended on the proteasomal pathway rather than the autophagy route. These findings also showed that although Gedunin degraded abnormal mHTT aggregates and intranuclear inclusions in cells from HD patient, it did not affect normal cells, thus providing a new perspective for using Gedunin to treat HD.
