OBJECTIVE:
To evaluate clinical value of electrocochleography in diagnosing the Meniere's disease.
METHOD:
Patients were saperated as having definite, probable and possible Meniere's disease according to the 1995 AAOHNS guidelines. Then set the probable and possible Meniere's disease as a suspected group. We used four different stimulus (clicks, 1000 Hz tone burst, 2000 Hz and 4000 Hz tone burst) to record electrocochleo-graphy. Those patients in each group received electrocochleography examination, and summating potential (SP)/action potential (AP) ratios were calculated. A prolonged action potential latency shift (AP shift) evoked by rarefaction and condensation clicks was also measured.
RESULT:
The click SP/AP positive rate in definite Meniere's disease group was 41.2%, tone burst at 1,000 Hz. 2,000 Hz,4,000 Hz were respectively 80.4%, 72.5%, 37.3%, AP shift positive rate was 45.1%. Using McNemar test, the positive rate of tone burst 1000 Hz (chi2 = 15.04, P < 0.01) and that of tone burst 2,000 Hz (chi2 = 8.65, P < 0.01) were statistically significant different when compared with that of click SP/AP, besides the tone burst at 1,000 Hz yielded has the highest sensitivity. The click SP/AP positive rate in suspected group and definite group were respectively 12% and 45.1% (chi2 = 6.610, P < 0.05) and AP shift positive rate of them were respectively 8.0% and 41.2% (chi2 = 10.460, P < 0.01). By chis-quare test, the positive rates of click SP/AP and AP shift between these two groups were statistically significant different.
CONCLUSION
Electrocochleography is a reliable test in the diagnosis of Meniere's disease. Compared with clicks, tone burst significantly has a higher sensitivity, especially at 1000Hz and 2000Hz frequencies. A prolonged action potential latency shift evoked by rarefaction and condensation clicks is also a useful addition to diagnosis Meniere' disease.

Objective:To investigate the effect of high-frequency repetitive transcranial magnetic stimulation combined with sertraline on depressive symptoms and self-injurious behaviors in adolescents with depression and non-suicidal self-injury.Methods:This study was a prospective study. A total of 112 adolescent patients with depression and non-suicidal self-injury who received treatment at the Third Hospital of Quzhou from January 2021 to September 2023 were included in this study. These patients were divided into a control group and a study group, with 56 patients per group, using the random digital table method. The control group was treated with sertraline, while the study group was treated with high-frequency repetitive transcranial magnetic stimulation combined with sertraline. The depression scores [assessed using the 24-item Hamilton Depression Scale (HAMD-24) and the Self-Rating Depression Scale (SDS)], self-injury status, and inflammatory factor levels (tumor necrosis factor-α, interleukin-10, and interleukin-1β levels) were compared before and after the intervention.Results:Before intervention, there were no statistically significant differences in HAMD-24 scores and SDS scores between the two groups (both P > 0.05). After intervention, both HAMD-24 scores and SDS scores decreased significantly in both groups (both P < 0.05). Additionally, the HAMD-24 scores [(13.46 ± 3.98) points] and SDS scores [(50.28 ± 5.13) points] in the study group were significantly lower than those in the control group [(19.89 ± 4.23) points, (71.62 ± 6.88) points, t = -8.28, -18.61, both P < 0.05]. Before intervention, there were no statistically significant differences in the number of self-injury incidents and self-injurious behavior scores between the two groups (both P > 0.05). After intervention, the number of self-injury incidents and the score of self-injurious behaviors significantly decreased in the study group compared with before intervention (both P < 0.05). After intervention, the number of self-injury incidents in the control group was decreased compared with before intervention ( P < 0.05), while the score of self-injurious behaviors did not differ significantly compared with before intervention ( P > 0.05). After intervention, the number of self-injury incidents [(2.15 ± 1.06) times] and the score of self-injurious behaviors [(2.41 ± 0.65) points] in the study group were significantly lower than those in the control group [5.43 ± 3.61) times, (12.04 ± 3.01) points, t = -7.78, -23.40, both P < 0.05]. Before intervention, there were no statistically significant differences in interleukin-1β, tumor necrosis factor-α, and interleukin-10 levels between the two groups (all P > 0.05). After intervention, interleukin-1β and tumor necrosis factor-α levels in the study group were significantly lower than those before intervention (both P < 0.05), while interleukin-10 levels in the study group were significantly higher than those before intervention ( P < 0.05). There were no statistically significant differences in the levels of interleukin-1β, tumor necrosis factor-α, and interleukin-10 between the pre- and post-intervention measurements in the control group (all P > 0.05). After intervention, interleukin-1β levels [(57.15 ± 6.33) ng/L] and tumor necrosis factor-α levels [(13.87 ± 5.91) ng/L] in the study group were significantly lower than those in the control group [(73.61 ± 8.52) ng/L, (17.12 ± 5.28) ng/L], while interleukin-10 levels [(1.62 ± 0.66) ng/L] were significantly higher than those in the control group [(1.19 ± 0.63) ng/L, t = -11.60, 3.53, -3.07, all P < 0.05]. Conclusion:High-frequency repetitive transcranial magnetic stimulation combined with sertraline can significantly reduce depressive symptoms and self-injurious behaviors in adolescents with depression and non-suicidal self-injury. The reason may be due to the decrease in inflammatory factor levels in patients.

Objective:To investigate the expression of microRNA (miR) -26a in human skin fibroblasts during photoaging induced by ultraviolet A (UVA) , and to evaluate the effect of up-or down-regulation of miR-26a expression on the methylation level of the whole genome, the target gene enhancer of zeste homolog 2 (EZH2) and cell aging.Methods:Some human skin fibroblasts were irradiated with 10 J/cm 2 UVA once a day for 7 consecutive days, RNA was extracted on days 0, 3 and 7, and real-time quantitative reverse PCR (RT-PCR) was performed to determine the expression of miR-26a; miR-26a mimics and inhibitors were transfected into fibroblasts to up-or down-regulate the expression of miR-26a respectively, and fluorescence microscopy and RT-PCR were performed to determine the expression of miR-26a and evaluate the transfection efficiency. Some human skin fibroblasts were divided into 6 groups: blank control group receiving no treatment, UVA group treated with UVA irradiation according to the above method, miR-26a mimic group transfected with miR-26a-mimics, UVA+miR-26a mimic group transfected with miR-26a-mimics followed by UVA irradiation, miR-26a inhibitor group transfected with miR-26a inhibitors, UVA+miR-26a inhibitor group transfected with miR-26a inhibitors followed by UVA irradiation. On day 7, cells in each group were collected after the end of UVA irradiation. Then, flow cytometry was performed to detect cell cycle, DNA methylation quantitative detection kit was used to detect the methylation level of whole genome, RT-PCR was conducted to determine the mRNA expression of EZH2 (a histone-lysine N-methyltransferase enzyme) , DNA methyltransferase 1 (DNMT1) and miR-26a, and Western blot analysis was performed to determine the protein expression of EZH2 and DNMT1. Statistical analysis was carried out by using one-way analysis of variance and least significant difference- t test. Results:Compared with the unirradiated control group, the expression of miR-26a gradually increased in the UVA irradiation group over time during the culture, and there was a significant difference in the expression of miR-26a between the two groups after 7 days of UVA irradiation ( t=5.295, P < 0.05) . Strong fluorescence signals were observed in the miR-26a mimic-or miR-26a inhibitor-transfected fibroblasts, suggesting a high transfection efficiency. Flow cytometry showed that the proportion of cells at G1 phase significantly differed among the blank control group, UVA group, miR-26a mimic group, UVA+miR-26a mimic group, miR-26a inhibitor group, and UVA+miR-26a inhibitor group (52.82% ± 2.56%, 78.56% ± 4.34%, 53.63% ± 3.13%, 89.52% ± 4.17%, 54.39% ± 3.86%, 65.34% ± 4.78%, respectively; F=46.728, P < 0.01) , and significantly higher in the UVA group than in the blank control group ( t=8.848, P < 0.01) , higher in the UVA+miR-26a mimic group than in the miR-26a mimic group and UVA group ( t=11.922, 3.154, P < 0.01, < 0.05, respectively) , and higher in the UVA+miR-26a inhibitor group than in the miR-26a-inhibitor group ( t=3.087, P < 0.05) , but significantly lower in the UVA+miR-26a inhibitor group than in the UVA group ( t=3.547, P < 0.05) . Detection of the genome-wide methylation level showed that the methylation level ( A450 value) significantly differed among the above groups (0.676 ± 0.024, 0.323 ± 0.043, 0.506 ± 0.035, 0.169 ± 0.024, 0.602 ± 0.036, 0.422 ± 0.029, respectively, F=97.402, P < 0.01) , and significantly lower in the UVA group than in the blank control group ( P < 0.01) , lower in the UVA+miR-26a mimic group than in the miR-26a mimic group and UVA group (both P < 0.01) , and lower in the UVA+miR-26a inhibitor group than in the miR-26a inhibitor group ( P < 0.01) , but significantly higher in the UVA+miR-26a inhibitor group than in the UVA group ( P < 0.05) . RT-PCR and Western blot analysis showed significant differences in the mRNA and protein expression of EZH2 and DNMT1 respectively among the 6 groups (both P < 0.05) , which were significantly lower in the UVA group than in the blank control group ( P < 0.05) , lower in the UVA+miR-26a mimic group than in the miR-26a mimic group and UVA group (both P < 0.05) , and lower in the UVA+miR-26a inhibitor group than in the miR-26a inhibitor group ( P < 0.05) , but significantly higher in the UVA+miR-26a inhibitor group than in the UVA group ( P < 0.05) . Conclusion:In the UVA irradiation-induced photoaging of skin fibroblasts, miR-26a expression was up-regulated, cellular proliferative activity and genome-wide methylation level decreased; up-regulation of miR-26a expression could down-regulate the expression of its target gene EZH2 and methylation-related gene DNM1, and promote cell photoaging, while down-regulation of miR-26a expression could up-regulate the expression of EZH2 and DNMT1, and inhibit cell photoaging.
