Objective To observe the efficacy and safety of intravitreal injection of ranibizumab in the treatment of retinopathy of prematurity (ROP).Methods Data from 49 consecutive ROP patients (95 eyes) including type Ⅰ pre-threshold,threshold and aggressive posterior ROP who had received anti-VEGF treatment for the first time in our hospital from June 2014 to August 2015 were collected.60 eyes from the 95 eyes were confined as the zone Ⅰ disease group,while the remaining 35 eyes as zone Ⅱ disease group.The difference of birth weight,gestational age,corrected gestational age,treatment effects,recurrence and re-treatment time between two groups were compared.0.025 mL ranibizumab (10 mg · mL-1) was injected through 1.5 mm puncture after corneal limbus by using 30G 1 mL injection syringe.At the end of the injection,tobramycin and dexamethasone ophthalmic ointment eye bag was used.After the injection of 3 days,the portable slit lamp and tonometer were used to observe the intraocular pressure,intraocular hemorrhage and endophthalmitis.The indirect ophthalmoscope was used to observe the retinal vascular tortuosity and ridge regression of lesion expansion at 1 week after treatment.At the same time,the systemic adverse reactions related to treatment were observed.Results After receiving ranibizumab treatment for the first time,93 eyes (95.9％) exhibited ROP regression after single injection,including 58 eyes in zone Ⅰ disease group,35 eyes in zone Ⅱ disease group.There was no statistical difference between two groups (P ＞ 0.05).22 eyes required additional anti-VEGF injection or laser treatment for ROP recurrence,including 17 eyes in zone Ⅰ disease group,5 eyes in zone Ⅱ disease group.There was statistical difference between two groups (P ＜0.05).The time from recurrence to re-treatment was (6.50 ±2.54) weeks,which in zone Ⅰ disease group was (6.44 ± 2.74) weeks and in zone Ⅱ disease group was (6.67 ± 2.31)weeks,there was no statistical difference between two groups (P ＞ 0.05).No local or systemic adverse events associated with the treatment or drug was observed within the following period.Conclusion Intravitreal injection of ranibizumab is an effective and well tolerated method for zone Ⅰ and zone Ⅱ ROP,but the recurrence rate is high.There Is no local or systemic adverse events associated with the treatment or drug.

OBJECTIVE: To understand the usage of MP3 and effects on hearing of middle school students in Xi'an, and discuss controlling strategies. METHOD: Stratified random cluster sampling method was used in the 1567 middle school students in Xi'an through questionnaire survey, ear examination and hearing examination, data were analysed by the SPSS13.0 statistical software. RESULT: 1) The rate of holding MP3 in the middle school students was 85.2%. Average daily use time was (1.41 +/- 1.11) h. 2) The noise group of pure tone hearing threshold was significantly higher compared with the control group (P<0.01), and increased the detection rate of hearing loss with the increasing use of MP3. 3) The detection rate of symptoms increased with the increasing use of MP3. CONCLUSION The usage of MP3 can harm hearing in middle school students, which can result in neurasthenic syndrome.

OBJECTIVE: To investigate the prevalence of vertigo and related risk factors in middle school students in the city of Xi'an. METHOD: A cross-section study was used to investigate on vertigo among middle school students. Questionnaire ,ear examination and auditory tests were carried out by the staff who received special training. Multiple Logistic regression models were used to analyze the relative influential factors about vertigo. RESULT: There were 1567 middle school students who underwent a complete investigation. The participants comprised 793 males (50.6%) and 774 females (49.4%). The overall prevalence of vertigo was 5.6%. No significant difference of the prevalence was found between males (4.7%) and females (6.5%) (P > 0.05). The use of MP3 or MP4, insomnia and history of middle ear infections or ototoxic drugs ingestion were the main risk factors for vertigo (odds ratio: 2.837, 5.582, 2.808 and 1.695, respectively). CONCLUSION Vertigo has an influence on the study and living of the students. More researches are urgently needed on prevention and treatment of vertigo.

OBJECTIVE: To retrospectively analysis the clinical data of facial nerve defects repair with greater auricular nerve graft. METHOD: The transmastoid approach was adopted to repair the facial nerve defects by means of nerve grafting. Preoperative and postoperative facial nerve functions were graded according to the House-Brackmann scale. RESULT: The patterns of temporal bone fracture in the 8 patients were longitudinal, most lesions occurred in the region of the second genu and its surrounding, preoperatively, all patients had Grade VI function. In 3 patients of facial nerve tumors, the tumors involved multiple nerve segments, and histologic results were all schwannomas, preoperatively, 1 case had Grade III function, 2 cases had Grade V function. In 2 patients of iatrogenic trauma of the facial nerve, the primary disease was chronic otitis media with cholesteatoma, the lesions were localized at the mastoid segment and the second genu respectively. In 1 patient of molten steel burn, the lesions was localized at the tympanic segment, preoperative facial nerve function was Grade VI. In addition to 3 cases lost to follow-up, the remaining patients, 4 recovered to a Grade III, 3 to a Grade VI, 2 to a Grade V and 2 remained at Grade VI. CONCLUSION In present study, the most common cause of facial nerve transection was temporal bone fracture. Facial nerve reconstruction by means of greater auricular nerve grafting was a practical and effective method, the best postoperative recovery of facial nerve function was Grade III.
