OBJECTIVE: To probe the factors that affect the pure-tone threshold glycerol test and the distribution of frequencies in positive glycerol test. METHOD: We tested the pure-tone threshold before and after glycerol intake in patients with Meniere's disease, and then analyzed the positive rates,distribution of positive frequencies and the time when the maximum threshold changes appeared. RESULT: The positive rate of pure-tone glycerol test was 72.09%, of which the threshold descending rate was 47.67%, and the threshold rebounding rate was 24.42%; the pure-tone threshold changes of descending group and rebounding group were (17.41 +/- 9.92) dB, (13.53 +/- 4.64) dB respectively, and the differences were significant. The distribution of positive frequencies were 250 Hz, 125 Hz, 500 Hz, 1 kHz, 4 kHz, 2 kHz, 8 kHz in descending order. The maximum pure-tone threshold changes mostly appeared within 2 or 3 hours after glycerol intake. CONCLUSIONS Patient selection, test occasion and the judgement criteria may affect the positive rate of glycerol test; the positive frequencies distribute in the low-frequency region mainly; the maximum pure-tone threshold changes mostly appeared within 2 or 3 hours after glycerol intake.

OBJECTIVE: To investigate the risk factors of tinnitus and provide evidence for tinnitus prevention. METHOD: Retrospectively analyzed the audiograms and the risk factors of 462 tinnitus victims who never perceived hearing loss, find the relationship between every risk factor and tinnitus. RESULT: The rate of tinnitus victims with high frequency hearing loss was the 46.1%, with low frequency hearing loss was 15.8%, with single middle frequency notch was 11.04%, with an audiogram like upset-basin was 7.58%, with normal audiogram was 14.07%, with other type of audiograms was 5.41%. The age distribution in the high frequency hearing loss group was mainly between 30 and 40 years, in the upset-basin hearing loss group was mainly older than 50 years, and in the other groups, mainly between 20 and 30 years. In the high frequency hearing loss group, male to female ratio was 158/55, in the low frequency hearing loss group and single middle frequency notch group ,male to female ratio was 14/59 and 12/39 respectively. In another three groups, the male to female ratio was nearly 1. Risk factors for high frequency hearing loss group, low frequency hearing loss, single middle frequency notch group and in the upset-basin hearing loss group were noise, fatigue, long-time musical instrument contact and ageing respectively. CONCLUSION Among the tinnitus victims who never perceived hearing loss, 86% of them have hearing impairment in high frequency area, low frequency area or single middle frequency. The rate of high frequency hearing loss was 46.01%, the major risk factor was noise, most of victims were men. The rate of low frequency hearing loss was 15.8%, the major risk factor was fatigue and nervous, most of the victims were women. The rate of single middle frequency notch was 11.04%, the major risk factor was long-time musical instrument contact. The rate of upset-basin hearing loss was 7.58%, ageing was the major risk factor.

Objective To explore the influence of psychological intervention on the immune function of patients with nasopharyngeal carcinoma. Methods Forty nasopharyngeal carcinoma patients with concomitant radiochemotherapy were divided into intervention group and control group by random digits table method with 20 cases each.Among concomitant radiochemotherapy nasopharyngeal carcinoma patients, intervention group were treated with comprehensive psychological behavior, and control group received only concurrent radiotherapy and chemotherapy. Both groups were investigated by Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS).Natural killer cells activity were measured by flow cytometry. Results There were no significantly difference in score of SDS and SAS between two confirmed groups(P>0.05).After treatment,the score of SDS and SAS in intervention group were(45.26± 3.83), (42.57 ± 3.75) points, which were significantly lower than those of control group (52.68 ± 3.66), (51.16 ± 3.62) points, the difference was statistically significant(t =6.264, 7.370, P<0.05). Meanwhile, natural killer cell activity between two groups showed no significantly difference (P>0.05). However, the activity of natural killer cells in intervention group was 26.96±9.01,which was higher than that of control group 22.84 ± 7.19, there were statistically significant difference between two groups (t=2.120, P<0.05).There was a positive correlation between the value difference of SDS scores,SAS scores and natural killer cell activity between two groups (r=0.238, P=0.006; r=0.527, P=0.003). Conclusions Comprehensive psychological intervention can significantly not only improve the depression and anxiety of nasopharyngeal carcinoma patients,but also enhance the activity of natural killer cells,which help maintain the leukocyte level of patients.

Objective:To analyze the difference of clinical characteristics and outcomes of infants with moderate and severe pediatric acute respiratory distress syndrome(PARDS)diagnosed according to baseline oxygenation index(OI) in pediatric intensive care unit(PICU).Methods:Second analysis of the data collected from the "Efficacy of pulmonary surfactant (PS) in the treatment of children with moderate and severe ARDS" program.Retrospectively compare of the differences in clinical data such as general condition, underlying diseases, OI, mechanical ventilation, PS administration and outcomes among infants with moderate and severe PARDS divided by baseline OI who admitted to PICUs at 14 participating tertiary hospitals from 2016 to December 2021.Results:Among the 101 cases, 55 cases (54.5%) were moderate and 46 cases (45.5%) were severe PARDS.The proportion of male in the severe group (50.0% vs.72.7%, P=0.019) and the pediatric critical illness score(PCIS)[72 (68, 78) vs.76 (70, 80), P=0.019] were significantly lower than those in the moderate group, while there was no significant difference regarding age, body weight, etiology of PARDS and underlying diseases.The utilization rate of high-frequency ventilator in the severe group was significantly higher than that in the moderate group (34.8% vs.10.9%, P=0.004), but there was no significant difference in PS use, fluid load and pulmonary complications.The 24 h OI improvement (0.26±0.33 vs.0.04±0.34, P=0.001) and the 72 h OI improvement[0.34 (-0.04, 0.62) vs.0.15 (-0.14, 0.42), P=0.029)]in the severe group were significantly better than those in the moderate group, but there was no significant difference regarding mortality, length of hospital stay and intubation duration after diagnosis of PARDS between the two groups. Conclusion:In moderate and severe(divided by baseline OI) PARDS infants with invasive mechanical ventilation, children in severe group have better oxygenation improvement in the early stage after PARDS identified and are more likely to receive high frequency ventilation compared to those in moderate group.Baseline OI can not sensitively distinguish the outcomes and is not an ideal index for PARDS grading of this kind of patient.
