ABSTRACT
OBJECTIVE: To explore the status and its influencing factors of anxiety symptoms in patients with occupational noise-induced deafness(ONID). METHODS: A total of 220 ONID patients were selected as the ONID group,and 200 healthy participants without noise exposure were selected as the control group by judge sampling method.The two groups were investigated by the Self-Rating Anxiety Scale, Self-Rating Depression Scale and Pittsburgh Sleep Quality Index. The Tinnitus Handicap Inventory was used to evaluate the disability levels of tinnitus, and pure-tone audiometry was used to assess the degree of tinnitus and hearing impairment in the ONID group. RESULTS: The incidence of anxiety, depression, and sleep disorder were higher in the ONID group than that in the control group(52.7% vs 9.0%, 55.0% vs 15.0%, 52.3% vs 7.0%, P<0.05). In ONID with anxiety subgroup, the duration of disease was longer(1.0 vs 2.0 years, P<0.01), incidences of tinnitus, depression and sleep disorder were higher than those in ONID without anxiety subgroup(92.3% vs 100.0%, 18.3% vs 87.9%, 19.2% vs 81.9%, P<0.01). The result of multivariate logistic regression analysis showed that the longer the duration of disease and the more severe of the tinnitus, the higher the risk of anxiety symptoms in patients with ONID [the odds ratio(OR) and its 95% confidence interval(CI) were 1.35(1.10-1.65) and 2.94(1.56-5.54) respectively, P<0.01]. The risk of anxiety in patients with sleep disorders was higher than those without sleep disorders [OR(95%CI) was 12.78(5.90-27.64), P<0.01]. CONCLUSION: The ONID patients are more likely to have anxiety. The duration of disease, severity of tinnitus and sleep disorders are the risk factors causing anxiety in ONID patients.
ABSTRACT
Objective To explore the relationship between the objective indexes and TCM syndromes of occupational hand arm vibration disease ,and to provide clinical data for the objectification of TCM syndrome differentiation. Methods 101 patients with occupational hand arm vibration disease were collected ,including 24 patients with Xingbi,39 with Tongbi and 38 with Zhuobi,according to the theory of traditional Chinese medicine syndrome differentiation ,the relationship was observed between different TCM Syndrome types and various of parameters,such as 5-and 10-minute rewarming rates in cold water rewarming test,terminal latency,amplitude, conduction velocity ,average time ,average amplitude of abductor pollicis brevis and abductor digiti minimi in electromyography. Results 5-and 10-minute rewarming rate in cold water rewarming test did not differ significantly among the three groups(P > 0.05). Amplitude of median nerve motor conduction differed significantly among the three groups of Xingbi,Tongbi and Zhuobi(χ2 = 6.14,P < 0.05),Further comparison between the groups was made in Xingbi and Tongbi(χ2=0.132,P=0.895),Xingbi and Zhuobi(χ2=2.277,P=0.023),Tongbi and Xingbi (χ2 = 2.172 ,P = 0.030). There were no significant differences among the three groups in latency and conduction velocity of the median nerve motor conduction and latency ,amplitude and conduction velocity of ulnar nerve motor conduction(P>0.05). The differences of conduction velocity and amplitude of median nerve and ulnar nerve sensory conduction,average time and average amplitude of abductor pollicis brevis and abductor muscle among the three groups had no statistical differences(P>0.05). Conclusions The distribution is different in the amplitude of median nerve motor conduction among the three groups of Xingbi,Tongbi and Zhuobi,further analysis shows that the difference is mainly reflected in the Xingbi group. We conclude that the median nerve axonal injury is lighter in Xingbi group than in the other two groups.

ABSTRACT
Objective@#Study of the results and the degree on occupational noise-induced deafness in-to the different high frequency hearing threshold weighted value, in order to provide theoretical basis for the re-vision of diagnostic criteria on occupational noise-induced deafness.@*Methods@#A retrospective study was con-ducted to investigate the cases on the diagnosis of occupational noise-induced deafness in Guangdong province hospital for occupational disease prevention and treatment from January 2016 to January 2017. Based on the re-sults of the 3 hearing test for each test interval greater than 3 days in the hospital, the best threshold of each frequency was obtained, and based on the diagnostic criteria of occupational noise deafness in 2007 edition, Chi square test, t test and variance analysis were used to measure SPSS21.0 data, their differences are tested among the means of speech frequency and the high frequency weighted value into different age group, noise ex-posure group, and diagnostic classification between different dimensions.@*Results@#1. There were totally 168 cases in accordance with the study plan, male 154 cases, female 14 cases, the average age was 41.18 ±6.07 years old. 2. The diagnosis rate was increased into the weighted value of different high frequency than the mean value of pure speech frequency, the weighted 4 kHz frequency increased by 13.69% (χ2=9.880, P=0.002) , 6 kHz increased by 15.47% (χ2=9.985, P=0.002) and 4 kHz+6 kHz increased by15.47% (χ2=9.985, P=0.002) , the difference was statistically significant. The diagnostic rate of different high threshold had no obvious differ-ence between the genders. 3. The age groups were divided into less than or equal to 40years old group (A group) and 40-50 years old group (group B) , there were higher the diagnostic rate between high frequency weighted 4 kHz (A group χ2=3.380, P=0.050; B group χ2=4.054, P=0.032) , weighted 6 kHz (A group χ2=6.362, P=0.012; B group χ2=4.054, P=0.032) , high frequency weighted 4 kHz+6 kHz (A group χ2=6.362, P=0.012; B group χ2=4.054, P=0.032) than those of speech frequency average value in the same group on oc-cupational noise-induced deafness diagnosis rate, the difference was statistically significant. There was no sig-nificant difference between age groups (χ2=2.265, P=0.944) . 4. The better ear's mean value of pure speech fre-quency and the weighted values into different high frequency of working years on each group were compared, working years more than 10 years group was significantly higher than that of average thresholds of each frequen-cy band in 3-5 group (F=2.271, P=0.001) , 6-10 group (F=1.563, P=0.046) , the difference was statistically significant. The different high frequency weighted values were higher than those of the mean value of pure speech frequency, and the high frequency weighted 4 kHz+6 kHz had the highest frequency difference, with an average increase of 2.83 dB. 5. The diagnostic rate into weighted different high frequency was higher in the mild, moderate and severe grades than in the pure speech frequency. In the comparison of diagnosis for mild occupational noise-induced deafness, in addition to the weighted 3 kHz high frequency (χ2=3.117, P=0.077) had no significant difference, the weighted 4 kHz (χ2=10.835, P=0.001) , 6 kHz (χ2=9.985, P=0.002) , 3 kHz+4 kHz (χ2=6.315, P=0.012) , 3 kHz+6 kHz (χ2=6.315, P=0.012) , 4 kHz+6 kHz (χ2=9.985, P=0.002) , 3 kHz+4 kHz+6 kHz (χ2=7.667, P=0.002) were significantly higher than the diagnosis rate of the mean value of pure speech frequency. There was no significant difference between the two groups in the moderate and se-vere grades (P>0.05) .@*Conclusion@#Bring into different high frequency hearing threshold weighted value in-creases the diagnostic rate of occupational noise-induced deafness, the weighted 4 kHz, 6 kHz and 4 kHz+ 6 kHz high frequency value affects the result greatly, and the weighted 4 kHz+6 kHz high frequency hearing threshold value is maximum the effect on occupational noise-induced deafness diagnosis.
ABSTRACT
OBJECTIVE: To analyze the impact of GBZ 49-2014 Diagnosis of Occupational Noise-induced Deafness and GBZ49-2007 Diagnostic Criteria of Occupational Noise-induced Deafness on the diagnosis of occupational noise-induced deafness( ONID). METHODS: A total of 84 individuals,who were workers exposed to noise and diagnosed as observation subjects by GBZ 49-2007 were selected as the subjects of study by judgment sampling. They were diagnosed based on the criteria of GBZ 49-2014 and GBZ 49-2007. The impact of different diagnostic audiometry,different age and gender correction methods and the inclusion of a weighting of 0. 1 high-frequency 4. 0 k Hz hearing threshold of GBZ 49-2014 on the diagnosis of ONID was analyzed. RESULTS: The binaural high frequency threshold average( BHFTA) calculated by GBZ 49-2014 were lower than that of GBZ 49-2007 [( 52. 1 ± 10. 3) vs( 52. 8 ± 10. 1) d B,P < 0. 05 ],but monaural threshold of weighted value( MTWV) of the good ear calculated by GBZ 49-2014 were higher than speech frequency threshold average( SPTA) of the good ear of GBZ 49-2007 [( 23. 2 ± 4. 1) vs( 19. 3 ± 4. 8) d B,P < 0. 01]. All of the 84 patients had BHFTA ≥40 d B and SPTA < 26 d B when diagnosed by GBZ 49-2007,and could not be diagnosed as ONID. A total of33. 3% patients had BHFTA ≥40 d B and MTWV ≥26 d B when diagnosed by GBZ 49-2014 which could be diagnosed as mild ONID. The detection rate of ONID was 21. 4% to 34. 5%( P < 0. 01) when the threshold of 4. 0 k Hz was used as the weighting diagnostic threshold of hearing in the case of using different diagnostic audiograms and different age and sex correction methods. CONCLUSION: A high-frequency hearing threshold of 4. 0 k Hz with a weighting of 0. 1 was included in GBZ 49-2014 as a diagnostic threshold,which reduced the diagnostic threshold of ONID.
