Objective To study the normal ranges and features for click-auditory brainstem responses of children in 3~5 years old.Methods Normal results of click-ABR from 132 normal children (224 ears)were ana-lyzed.The children were divided into three groups:Group A (74 ears from children of 3 years old),Group B (78 ears from children of 4 years old)and Group C (72 ears from children of 5 years old).The ABR data were statisti-cally analyzed by ANOVA with SPSS.Results At 80 dB nHL,the wave Ⅰ,Ⅲ,and Ⅴ latencies and intervals of wave Ⅰ- Ⅲ,and wave Ⅰ-Ⅴ of ABR for 3 -year old children were 1.24 ±0.09 ms,3.53 ±0.16 ms,5.39 ± 0.23 ms,2.30±0.15ms and 4.15 ±0.22 ms,respectively,and for 4 -year-old children,they were1.23 ±0.10 ms,3.52±0.39 ms,5.30±0.21 ms,2.28±0.39 ms and 4.07 ±0.22 ms,respectively.For 5 - year-old chil-dren,they were1.24±0.10 ms,3.67±0.63 ms and 5.34±0.19 ms,2.42±0.63 ms and 4.09±0.19 ms,respec-tively.The thresholds for 3-year children were 22.57 ±4.40 dB nHL,for 4 - year children,21.15 ±4.83 dB nHL,and for 5 - year children,21.11±3.48 dB nHL.Among three groups,only latency of wave V and interval of wave I-V had statistical differences,and a further analysis showed the statistical differences in Groups A and B. No statistical differences were observed in Groups B and C.The latency of wave I and thresholds of ABR for the children of different ages were not significantly different.Conclusion The resvits of this study suggest the brainstem may mature at 4 years old.

Radiotherapy is a major local treatment for cervical cancer.However, local uncontrollability due to radioresistance is still common.Therefore, the prediction of radiosensitivity is quite beneficial to develop an optimal treatment strategy for individual patients.Multiple factors could influence the radiosensitivity of cells, and p53 status is one of them.The upstream or downstream molecules of p53 could also be regulated to affect the radiosensitivity of cervical cancer.The aim of the review is to analyze the difference in p53 status between different types of cervical cancer and to discuss how p53 regulates the response to radiotherapy.
