Objective　To evaluate whether the stimulation on eyes of bendazac lysine eyedrops could be reduced by cold storage.Methods　 Mate design scheme and double-blind clinical trial were performed. 160 healthy eyes was divided into two groups: the test group was given bendazac lysine eyedrops which was stored in refrigerator at 4℃ over night, and the control group was given it which was stored at room temperature.Results　ln the control group and the test group, the occuring rate of stimulation was 19.30% and 6.25%. The cases of B、C stimulation degrees were 31 and 10; the average stimulation degrees of each group were 1.21 and 1.07, the scoring change for eye stimulation were 1.57±1.50,0.79±1.40,all respectively. The statistical difference was significant (P＜0.05 or P＜0.01).Conclusion　The eye stimulation of bendazac lysine eyedrops can be reduced by cold storage.

High-risk human papillomavirus (HPV) persistent infection is the most common cause of cervical cancer and precancerous lesions. As a primary prevention measure, especially in developing countries, HPV vaccine can greatly reduce the incidence of cervical cancer.However, researches on the safety, efficacy, and coverage of the HPV vaccine still remain insufficient. Therefore, in this review, we outlined the recent research progress of the HPV vaccine in terms of immunogenicity, safety, efficacy, latest vaccination concepts and strategies. It may provide a theoretical basis for further research on the use of the HPV vaccine.
