Based on the COI gene sequence, 13 species of Acrossocheilus were analysed. The results showed that the genetic distance between species of Acrossocheilus is more than 0.020 0 except for the genetic distance between A. beijiangensis and A. stenotaeniatus (0.015 7). In the phylogenetic tree, A. beijiangensis and A. stenotaeniatus formed as the same clade, which genetic distance less than the level of species classification. The two species may be the same species with two different names. The genetic distance from A. jishouensis, A. parallens and A.hemispinus protrudated into sister branches in phylogenetic tree, and the genetic distance from both was obviously greater than 0.020 0, which showed that A. jishouensis is an effective specie. A. hemispinus and A. cinctus were distributed in two independent branches of the phylogenetic tree, and the genetic distance between them is larger than that between the species on the same branch, so they should be regarded as two separate species. The results of this study indicate that mitochondrial COI gene sequences are effective for species identification and can be used to explore the phylogeny of Acrossocheilus.

Laparoscopic surgery is a clinically effective technique for diagnosing and treating a wide range of diseases in veterinary medicine that can reduce injury to abdominal muscles and nerves,intraoperative strain on organs, and postoperative pain and infection risk. Most models for practicing laparoscopic skills in minimally invasive veterinary surgery are currently general task trainers, which consist of simulators for training humans in surgery and have limitations such as species anatomical differences and surgical procedure differences. This article elaborates on the application of surgical simulators and surgical training in veterinary laparoscopic surgery training from the aspects of tasks, time allocation schemes,and types of simulators. To promote the use of laparoscopic technology in veterinary clinical practice, veterinarians must develop more simulators and surgical training courses specifically for veterinary laparoscopic surgery training.
