Objective: To study the antiemetic effect of the ethyl acetate extract with ethanol extraction of Galangal (hereinafter referred to as galangal extract) in allotriophagic Kaolin model rats.Methods: The rats were administered respectively with chemical drug cisplatin and apomorphine, and received the rotation stimulation as well.Three types of allotriophagic Kaolin models were established, and apomorphine, ondansetron and metoclopramide were used as the control drugs.The experimental rats were divided into 3 groups at low, medium and high dose of Galangal extract with prophylactic effect.The antiemetic effect was observed after the treatment.Results: Chemical drug cisplatin (3.0 mg·kg-1, intraperitoneal injection) and apomorphine (3.2 mg·kg-1,subcutaneous injection) and the rotation stimulation (centrifugal force of 3.4×g,60min) could induce allotriophagic vomiting in rats.The galangal extract at low (1 500 mg·kg-1), medium (4 500 mg·kg-1) and high (9 000 mg·kg-1) dose all fail to effectively inhibit the allotriophagic Kaolin behavior of rats caused by cisplatin, apomorphine and rotation(P>0.05).Conclusion: Galangal extract can not effectively inhibit the vomiting of allotriophagic Kaolin model rats.Probably, there is no correlation between the pharmacological effects of galangal extract and substance P, 5-hydroxytryptamine, dopamine as well as receptive zone of chemical vomiting inhibition.

Objective To analyze and provide reference for developing clinical practice guidelines of ostomy care suitable for the domestic health care settings. Methods Content analysis method was used to analyze clinical practice guidelines searched from the Internet. Results A total of 13 clinical practice guidelines were included. All the guidelines were published between 2005 to 2016 without update. Four of them were evidence-based guidelines, the rest were not. A total of 21 items were identified as being related to ostomy care. Conclusions Although the existing clinical practical guidelines are instrumental to guiding clinical ostomy care practice, most of them were not evidence-based guidelines without high methodological quality. Meanwhile, some guidelines lack specific and updating recommendations for ostomy care, which may cause problems in ostomy care practice. What′s more, some recommendations may not suit for China because they were made in the foreign circumstance. Researchers and clinical nurses should develop local practice guidelines of ostomy care with consideration of the actual medical conditions in China and the best evidence.
