This paper introduces Professor LIU Zhibin 's clinical experience in the treatment of subjective tinnitus with acupuncture based on the "kidney-bone-brain" axis. Professor LIU proposes that the disease is most closely related to the kidney and brain. The lesion is located in the brain, and the pathogenesis is kidney essence deficiency, marrow sea loss, and ear orifice dystrophy. The "kidney-bone-brain" shows close correlation in physiological function, pathological changes and treatment. According to the "kidney-bone-brain" axis, Professor LIU proposes that the treatment of subjective tinnitus should be tonifying kidney qi, tonifying essence and filling marrow, and the principle of local acupoint selection, touching bone acupuncture, matching distal acupoints and proximal acupoints, tonifying kidney and benefiting brain should be adopted. The acupoints of Tinggong (SI19) and Yifeng (TE17) are selected to be treated with touching bone acupuncture, combined with Taixi (KI3), Shenshu (BL23), Baihui (GV20) and Shenting (GV24), so as to achieve common benefit of kidney, bone and brain, and multi-angle treatment.

After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

OBJECTIVES: This study aimed to investigate the correlation between clinical symptoms and unilateral chewing habits in patients with temporomandibular disorder (TMD) accompanied by tinnitus. METHODS: A total of 285 patients diagnosed with TMD at the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital between December 2020 and May 2024 were included and divided into two groups: tinnitus group and non-tinnitus group. Analysis was conducted on the proportion of patients with unilateral chewing habits in both groups, the correlation between the side of tinnitus and the side of unilateral chewing, and the correlation of tinnitus with TMD clinical symptoms (joint clicking, joint pain, and limited mouth opening) and unilateral chewing habits. The correlation of the type of disc displacement with unilateral chewing and tinnitus was also examined. RESULTS: In the tinnitus group, the proportions of patients with and without unilateral chewing habits were 90.70% (39/43) and 9.30% (4/43), respectively. In the non-tinnitus group, the proportions of patients with and without unilateral chewing habits were 76.03% (184/242) and 23.97% (58/242), respectively. The proportion of patients with unilateral chewing habits in the tinnitus group was significantly higher than in the non-tinnitus group (χ²=4.613, P<0.05). Correlation analysis showed a positive correlation between tinnitus and unilateral chewing habits (P<0.05). In the left-sided tinnitus group, the proportion of left-sided unilateral chewers [54.55% (12/22)] was higher than that of right-sided unilateral chewers [45.45% (10/22)]. In the right-sided tinnitus group, the proportion of right-sided unilateral chewers [81.82% (9/11)] was higher than that of left-sided unilateral chewers [18.18% (2/11)]. The difference was statistically significant (χ²=7.282, P<0.05). A positive correlation was also found between the side of tinnitus and the side of unilateral chewing habits (P<0.05). The proportion of patients with pain was significantly higher in the tinnitus group than in the non-tinnitus group (P<0.05). No significant difference in the proportion of joint clicking or limited mouth opening and disc displacement (no disc displacement, unilateral disc displacement, bilateral disc displacement, reducible disc displacement, or irreducible disc displacement) was found between the tinnitus and non-tinnitus groups (P>0.05). CONCLUSIONS TMD with unilateral chewing habits may be a contributing factor to unexplained tinnitus. Unexplained tinnitus is correlated with joint pain in patients with TMD.

This article summarizes the clinical experience in treatment of refractory tinnitus with He's santong therapy of acupuncture (three techniques of acupuncture to remove the blockage and promote circulation). Refractory tinnitus is characterized by a mixture of deficiency and excess, which is implicated in the dysfunction of zangfu organs, resulting in physical and mental injuries. In association with the complicated conditions of the diseases and etiology, He's santong therapy of acupuncture is adopted. The needling with filiform needles acts directly on the affected site to regulate the mind and improve the hearing, the fire needling works on removing the refractory illness and blockage through heating up, and bloodletting on activating blood circulation and promoting qi flowing to eliminate the pathogens. The three techniques of acupuncture co-work on harmonizing the mind, promoting the circulations in the ear to stop tinnitus.

This article introduces Professor SUN Hua's clinical experience of acupuncture for treating subjective tinnitus. Professor SUN advocates combining meridian differentiation, syndrome differentiation, and disease differentiation in clinical practice. For excess syndrome of subjective tinnitus, acupuncture aims to unblock the shaoyang meridian and regulate qi and blood. For deficiency syndrome, the focus is on tonifying the yin and essence of liver and kidney. Emphasizing the importance of calming the shen (mind), Professor SUN employs a three-pronged approach: using the "four shen regulating needles" to calm the mind, the Siguan points (Hegu [LI 4] and Taichong [LR 3]) to regulate qi movement of the internal organs, and Shenmai (BL 62) and Zhaohai (KI 6) to balance yin and yang, treating both the physical and psychological aspects to effectively alleviate tinnitus.

Background: Tinnitus is a common disorder that causes significant morbidity; however, the neurophysiological mechanism is not yet fully understood. A relationship between tinnitus and limbic system has been reported. As a significant component of the limbic system, the hippocampus plays an important role in various pathological processes, such as emotional disturbance, decreased learning ability, and deterioration of memory. This study was aimed to explore the role of the hippocampus in the generation of tinnitus by electrophysiological technology. Methods: A tinnitus model was established in rats through intraperitoneal injection of salicylate (SA). Subsequently, the spontaneous firing rate (SFR) of neurons in the hippocampal CA1 area was recorded with in vivo multichannel recording technology to assess changes in excitability induced by SA. To investigate the effect of excitability changes of hippocampus on the auditory pathway, the hippocampus was electrically stimulated and neural excitability in the auditory cortex (AC) was monitored. Results: Totally 65 neurons in the hippocampal CA1 area were recorded, 45 from the SA group (n = 5), and 20 from the saline group (n = 5). Two hours after treatment, mean SFR of neurons in the hippocampal CA1 area had significantly increased from 3.06 ± 0.36 Hz to 9.18 ± 1.30 Hz in the SA group (t = -4.521, P < 0.05), while no significant difference was observed in the saline group (2.66 ± 0.36 Hz vs. 2.16 ± 0.36 Hz, t = 0.902, P > 0.05). In the AC, 79.3% (157/198) of recorded neurons showed responses to electrical stimulation of the hippocampal CA1 area. Presumed pyramidal neurons were excited, while intermediate neurons were inhibited after electrical stimulation of the hippocampus. Conclusions The study shows that the hippocampus is excited in SA-induced tinnitus, and stimulation of hippocampus could modulate neuronal excitability of the AC. The hippocampus is involved in tinnitus and may also have a regulatory effect on the neural center.

OBJECTIVETo explore the effects of electrical stimulation at acupoints in the distribution area of auricular vagus nerve combined with sound masking on auditory brainstem response (ABR) and contents of neurotransmitters of γ-aminobutyric acid (γ-GABA), 5-hydroxytryptamine (5-HT) and acetyl choline (Ach) in inferior colliculus of tinnitus rats.

METHODSTwenty-four male adult SD rats were randomized into a control group, a model group, a 7-d treatment group and a 15-d treatment group. Except the control group, rats in the remaining groups were treated with intraperitoneal injection of 10% salicylate sodium at a dose of 350 mg/kg to establish tinnitus model. Rats in the control group were treated with injection of 0.9% NaCl. Rats in the 7-d treatment group and 15-d treatment group were treated with electrical stimulation at "Shenmen (TF₄)" and "Yidan (CO₁₁)" in the distribution area of auricular vagus nerve combined with sound masking, once a day, for 7 days and 15 days. The SigGenRP software of TDT system was applied to provide voice for single ear and collect the signal, and the voice threshold of ABR was tested. The levels of γ-GABA, 5-HT and Ach in inferior colliculus of rats were detected by enzyme linked immunosorbent assay (ELISA) and compared.

RESULTSCompared with the model group, the threshold values of ABR in 12 kHz and 16 kHz voice stimulation in the 7-d treatment group were significantly lower all P < 0.05); the threshold values of ABR from 4 kHz to 28 kHz voice stimulation in the 15-d treatment group were signally reduced (P < 0.05, P < 0.01), which was more significant than those in the 7-d treatment group. The level of γ-GABA in the model group was significantly lower than that in the control group (P < 0.05), and that in the 15-d treatment group was apparently higher than that in the model group (P < 0.05). The level of 5-HT in the model group was markedly higher than that in the control group (P < 0.05), and that in the 7-d treatment group was lower than that in the model group (P < 0.05), while that in the 15-d treatment group was apparently higher than that in the model group (P < 0.05). The level of Ach in the model group was obviously; lower than that in the control group (P < 0.05), and that in the 7-d treatment group was higher than that in the model group (P < 0.05).

CONCLUSIONElectrical stimulation at auricular vagus nerve combined with sound masking) could regulate the threshold of ABR, especially in the 15-d treatment group. This may be ascribed to modulating the levels of neurotransmitter of γ-GABA, 5-HT and Ach in inferior colliculus.

BACKGROUNDMeniere's disease is a unique, progressive disease of the inner ear. The complex manifestation presents diagnostic challenges. The cochlear symptoms often present before vertigo and tend to be ignored. This study aimed to analyze the characteristics of cochlear symptoms and functions associated with Meniere's disease to investigate the regularity of the development of this disorder.

METHODSOne-hundred fifteen patients who were diagnosed with definite unilateral Meniere's disease at the Hearing and Vestibular Clinic of the Department of Otorhinolaryngology of Beijing Tongren Hospital from August 2013 to November 2015 were recruited in this retrospective study. Initial symptoms, duration from initial symptoms to the diagnosis, hearing thresholds, audiogram patterns, and caloric test results were collected and analyzed for each patient. Data were analyzed using SPSS 13.0 statistical software by Spearman's correlation, Kruskal-Wallis H test, Chi-square test, and Fisher's exact test.

RESULTSThe average hearing threshold of these patients was 45.24 ± 18.40 dB HL. A majority of the patients (55.65%) were in Stage 3. The initial presentation of the disorder in 58 cases (50.43%) comprised only cochlear symptoms without vertigo. A weak, positive correlation was found between the degree of hearing loss and duration of the disease from initial symptoms to the diagnosis (rs = 0.288, P = 0.002). Upward-sloping, inverted "V," downward-sloping, and flat pattern were the main audiometric patterns observed with a distinctive distribution between stages (P < 0.001). Based on the configurations of audiograms, the audiometric patterns had a weak correlation to the duration (rs = 0.269, P = 0.004), and there was a tendency of duration to rising from upward-sloping, inverted "V", downward-sloping to flat pattern. (H = 10.024, P = 0.018). Frequencies of tinnitus in 56 patients (64.4%) were at the lowest points of the audiograms, i.e., the frequencies of the poorest hearing threshold. The patients at an advanced stage (Stage 3 [56] and Stage 4 [73]) exhibited a significantly higher abnormality of canal paresis than those at the earlier stages (Stage 1 [23] and Stage 2 [42]) (χ2 = 5.973, P = 0.015).

CONCLUSIONSPatients with definite Meniere's disease always have a moderate to severe sensorineural hearing loss before diagnosis. Cochlear symptoms are the most common initial presentation. With the progression of the duration, the hearing impairment becomes more severe and the distribution of the audiometric pattern is distinctive between stages.

OBJECTIVE: To analyze the abnormal conditions of the affected ear and the contralateral ear of patients with unilateral Meniere's disease and the prevalence of bilateral abnormalities among these unilateral Meniere disease population, providing reference for the clinical treatment strategies for Meniére disease. METHOD: A retrospective analysis of 106 Meni6re disease cases was performed, the abnormal incidence of the affected ears, the contralateral ears and the bilateral abnormalities were calculated, and the disease characteristics were analyzed. RESULT: The bilateral ears abnormal incidence of unilateral Meniére disease was 35. 85% (38/106); the cochlear symptoms of the contralateral ears often occurred 2. 25 years later of the symptoms of Meni6re disease; contralateral cochlear symptoms included at least two symptoms of tinnitus, deafness and ear fullness; 39. 47%(15/38) patients with bilateral abnormalities would appear binaural hearing impairment. CONCLUSION This study showed that about one-third of unilateral Meniére diseases have binaural symptoms, among which about one-third would occur bilateral hearing loss. Therefore, it is necessary to consider the course of disease and the symptoms of the contralateral ear before taking damage or destructive method for treating Meniére's disease clinically.

OBJECTIVETo compare the difference of the clinical efficacy in treatment of nervous tinnitus of kidney deficiency between the combined therapy of Zhuang medicine at Qineihuan point combined with the conventional acupuncture and simple conventional acupancture.

METHODSSixty patients were randomized into an observation group and a control group, 30 cases in each one. In the control group, the conventional acupuncture was applied to Taixi (KI 3), Zhaohai (KI 6), Tinggong (SI 19) and Waiguan (TE 5), etc. and the needles were retained for 30 min. In the observation group, on the basic treatment as the control group, Zhuang medicine acupuncture at Qineihuan point was added. The treatment was given once every day, 10 treatments made one session and there were 2 days of interval between the sessions. In 3 sessions of treatment, the changes of tinnitus were observed and the clinical efficacy was evaluated.

RESULTSAfter treatment, tinnitus score and tinnitus grade were all improved as compared with those before treatment in the two groups (all P<0. 05) and the results in the observation group were better than those in the control group (all P<0. 05). The curative and remarkably effective rate was 63. 3% (19/30) and the total effective rate was 93. 3% (28/30) in the observation group, better than 30. 0% (9/30) and 73. 3% (22/30) in the control group (both P<0. 05).

CONCLUSIONThe combined therapy of Zhuang medicine at Qineihuan point and conventional acupuncture achieves the better efficacy on nervous tinnitus of kidney deficiency as compared with the simple conventional acupuncture.
