Correlation between auditory-vestibular functions and estrogen levels in postmenopausal patients with Meniere's disease.

BACKGROUND: To investigate auditory and vestibular functions, estrogen levels, and its clinical correlation in postmenopausal females with Meniere's disease (MD). METHODS: We retrospectively analyzed the serum estradiol (E2) levels and the auditory and vestibular functions measured by auditory brainstem response (ABR) to high click rate, pure-tone audiometry (PTA), and caloric test on postmenopausal women who suffered from MD or not at the Specialist Clinic of Vertigo, Shandong Provincial Hospital, during September 2010 to October 2014. RESULTS: A total of 76 postmenopausal patients with MD and 50 healthy postmenopausal controls were included. The patients with MD had lower estrogen levels (22.50 ± 16.66 pg/mL vs 30.69 ± 18.59 pg/mL, P = 0.011), longer I-V interpeak latency of ABR (left 0.22 ± 0.16 mseconds vs 0.18 ± 0.10 mseconds, P = 0.118; right 0.24 ± 0.13 mseconds vs 0.17 ± 0.09 mseconds, P = 0.001), and higher unilateral weakness (UW) value (P < 0.001) in comparison with the controls. The mean pure-tone thresholds of at the speech frequency (500 Hz, 1 kHz, 2 kHz, and 3 kHz) were significantly elevated in patients with MD than those in the controls (left P < 0.001, right P < 0.01). The estradiol level of patients with MD was correlated with ABR latency (left r = -0.229, P < 0.05; right r = -0.220, P < 0.05) and UW value (r = -0.328, P < 0.05), but not with mean pure-tone threshold. CONCLUSIONS: Estrogen levels correlated with auditory and vestibular function in postmenopausal patients with MD. Low estrogen may be involved in the microcirculatory disturbance of the inner ear, affecting the occurrence and development of MD.

Effect of Naohuandan Capsule in Treating Mild and Moderate Cases of Vascular Dementia / 广州中医药大学学报

To observe the therapeutic effect of Naohuandan Capsule (mainly composed of Radix Ginseng, Radix Rehmanniae Preparata,etc.) in treating mild and moderate cases of vascular dementia (VD).Forty five cases of VD, which are subjected to the diagnostic standard of American Association of Psychiatry (DSM Ⅳ), were randomly allocated to two groups for a 3-month treatment course. Group A (n=22) was treated with Naohuandan Capsule and Group B (n=23) with Naofukang Tablet. Therapeutic effect was evaluated by scoring of mini-mental state examination (MMSE) and activity of daily living (ADL) and serum levels of estradiol (E 2) and testosterone (T) were also observed.Scores of MMSE and ADL were increased, E 2 and T levels were elevated and the ratio of E 2/T was decreased in Group A(P0 05). [Conclusion]Naohuandan Capsule has a definite effect in preventing and treating VD and its mechanism may be related to the increase of E 2 and T levels, decrease of E 2/T ratio and the regulation of neuroendocrine function.
