In recent years, with the widespread application of high-density intensification and other facility fisheries, fish production per unit area has increased significantly.At the same time, higher requirements have been placed on the management of fishery breeding processes.The outbreak of fish diseases, especially viral diseases is the main factor, which harms the fish breeding industry.It has the characteristics of rapid onset, wide range and high fatality rate.Its outbreak often causes serious economic losses.There are no specific drugs to control fish viral diseases.Vaccines are better virus inhibitors, which can effectively inhibit the proliferation of specific viruses and provide early prevention.Therefore, the research on fish vaccines has received widespread attention.This paper introduces the development process of fish vaccines and summarizes the types and immunization methods of fish vaccines.It provides reference information for the research of fish vaccines.

Acoustic neuromas is a common posterior fossa tumor in neurosurgery, accounting for about 8% of intracranial tumors. At present, the clinical treatment modality of acoustic neuroma is still dominated by neurosurgical treatment. Most acoustic neuromas have abundant blood supply, hypervascular acoustic schwannomas are often encountered clinically, to deal with this kind of acoustic neuroma, it is particularly important to evaluate the blood supply and vascular distribution before operation. Therefore, this article reviews the blood supply of acoustic neuroma and its clinical significance, etc. [ABSTRACT FROM AUTHOR]

Acostic neuromas are considered to be one of the most difficult intracranial tumors to remove without producing additional neurological deficit. Despite the advances in intraoperative cranial nerve monitoring and neurosurgical techniques, postoperative nerve dysfunction is still an important issue with paralysis of the facial nerve. It’s known that the facial nerve is included in the peripheral nervous system. The process includes the treatments of facial palsy and the mechanisms of nerve regeneration， such as interactions between neural axons and Schwann Cells， changes of the growth cone， etc． It’s reviewed that advanced research on regenerating mechanism of injured facial nerve in this article.

Objective To evaluate the effect of GLP-1 receptor agonists on the fracture risk in patients with type 2 diabetes mellitus. Methods PUBMED，MEDLINE，the Cochrane Library，EMBASE，Web of Science，CNKI，and Wanfang data base were searched. The randomized controlled trials (RCT) of GLP-1 receptor agonists for the treatment of type 2 diabetes mellitus were collected according to the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5. 0 software and Stata 12. 0 software. Results Thirty-six RCTs were included. The result of meta-analysis showed that the incidence of fracture in liraglutide group was significantly lower than that in the control group，and the difference was statistically significant (OR = 0. 47，95% CI 0. 24，0. 91，P = 0. 024) . No significant difference was shown in the incidence of fracture between control group and GLP-1 receptor agonists group (OR = 0. 94，95% CI 0. 64，1. 37，P = 0. 735) ，exenatide (OR = 1. 81，95% CI 0. 83，3. 95，P = 0. 139) ，dulaglutide (OR = 1. 21，95% CI 0. 57，2. 58，P = 0. 616) ，lixisenatide (OR = 1. 27，95% CI 0. 50，3. 24，P = 0. 617) ， and albiglutide (OR = 0. 70，95% CI 0. 25，2. 20，P = 0. 515) ，respectively. In the aspects of the risk factors of fracture，bone mineral density and serum calcium，there were no significant differences between GLP-1 receptor agonists group and the control groups (OR = 0. 16，95% CI -0. 10，0. 42，P = 0. 223 and SMD = 0. 17，95% CI -0. 20，0. 55，P = 0. 358，respectively) .Conclusion The use of liraglutide reduces fracture risk in patients with type 2 diabetes mellitus. However，the use of other antidiabetic drugs or other GLP-1 receptor agonists has similar fracture risk compared with the control group. In addition，the effect of GLP-1 receptor agonists on bone mineral density and serum calcium is similar to that of the control group. [ABSTRACT FROM AUTHOR]
