Objective:To investigate the relationship between symptoms of vertigo and vestibular functions and short-term hearing outcomes in patients with flat descending sudden sensorineural hearing loss （SSNHL）. Methods:A retrospective review was conducted of the vestibular symptoms observed in 48 patients with unilateral flat-down sudden sensorineural hearing loss treated at the Department of Otolaryngology Head and Neck Surgery, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine. Symptoms of vertigo and the results of cervical vestibular-evoked myogenic potentials （cVEMP）, ocular VEMP （oVEMP）, caloric test and video head-impulse test （vHIT） were collected to determine whether these factors could predict therapeutic efficacy. Results:The symptoms of vertigo was not correlated with prognosis （P>0.05） or with abnormal vestibular functions （P>0.05）. Patients with abnormal cVEMP, oVEMP, caloric test or vHIT showed significantly lower effective rates （32.0%, 44.0%, 32.0%, and 24.0%, respectively）; the greater the number of abnormal tests, the poorer the outcome. Patients with all four tests abnormal gained only （3.13±15.97） dB HL in hearing recovery, whereas those with normal cVEMP, oVEMP, caloric test or vHIT showed better chances of hearing improvements by （29.22±20.31）, （31.18±21.59）, （26.17±21.31）, and （26.38±24.05） dB HL, respectively. Conclusion:Vestibular function effectively predicts prognosis in flat descending SSNHL. Patients with abnormal vestibular tests, regardless of symptoms of vertigo, responded poorly to treatment, whereas those with normal cVEMP, oVEMP, caloric test and vHIT results achieved better hearing recovery. Abnormal vestibular function implies more extensive and severe inner-ear lesions in patients with SSNHL.

OBJECTIVE: To evaluate the effect of general anesthesia on postoperative melatonin secretion in 4-to 6-year-old children with snoring. METHODS: Twenty children with snoring aged 4-6 years of either gender (ASA grade Ⅰ and Ⅱ) were selected for adenoidectomy.Before, during and 3 days after the operation, salivary melatonin levels of the children were measured at 11 selected time points (T1-T11).The illumination intensity and body temperature of the children were recorded at each time point of measurement.The sleep time of the children in 3 days after the operation was recorded, and postoperative pain scores (FLACC) and Riker and Rehabilitation Quality Rating Scale-15(QoR-15) scores were assessed.Sleep Apnea Life Quality Evaluation Questionnaire (OSA-18) was used to evaluate postoperative recovery of the children at 28 days after the operation.The incidence of major adverse events of the children during hospitalization was recorded. RESULTS: No significant difference was found in baseline salivary melatonin level among the 20 children before the operation.Salivary melatonin level at 7 am after the operation (T8) was significantly lowered as compared with that before the surgery (T4)( CONCLUSIONS In preschool children with snoring, general anesthesia affects but does not inhibit melatonin secretion on the first night after surgery, and minor surgeries under general anesthesia in the morning do not cause significant changes in melatonin secretion to cause disturbance of the circadian rhythm in these children.

Objective To discuss the high-risk human papillomavirus (HPV )infection in the Guangxi .Methods A total of 26 796 copies of the test results for female cervical secretions specimens were analyzed retrospectively from what the second-genera-tion hybrid capture technology mixed detect 13 kinds of high-risk HPV viral DNA .Results Infection rate was 17 .94% in Guangxi , and the infection of HPV in north was higher than other regions ,and the differences of regions had statistically significant (P<0 .05) .The peak age of infection in the Guangxi region was less than 20 years old ,50- <60 years old ,and equal or more than 60 years old .The differences among age groups was statistically significant(P<0 .05) .Patients constitute HPV infection Guangxi re-gion had high viral load for 40 .93% ,and high viral load constituent ratio rise with age .Conclusion The existence of high-risk HPV infection is regional different and age different in the Guangxi region ,to high-prone areas ,infection high age should focus on monito-ring ,high viral load in patients with complete cervical cytology and histology examination if necessary .
