Methods Fifty-eight cases were randomized into an acupuncture plus medication group （28 cases, 32 damaged ears） and a western medicine group （30 cases, 34 damaged ears）. In the acupuncture plus medication group, the comprehensive therapy of electroacupuncture and western medicine was used. The main points were ěrmén （耳门 TE 21）, Tīnggōng （听宫 SI 19）, Tīnghuì （听会 GB 2）, Yìfēng （翳风 TE 17）, etc. The western medicine therapy was the comprehensive treatment with vasodilators, the medicines for promoting nerve function and releasing inner ear edema and hyperbaric oxygen. In the western medicine group, the western medicine comprehensive therapy was adopted. 10-day treatment made one session. Two sessions of treatment were required. In 1 or 2 sessions of treatment, the efficacy was observed, the electric audiometry was evaluated. Additionally, the blood routine and liver and kidney functions were detected. Results The total effective rate was 50.0% （16/32） in the acupuncture ＋ medication group and was 55.9% （19/34） in the western medicine group. The efficacies were similar between the two groups （P〉0.05）. In 1 and 2 sessions of treatment, at 250 Hz, 500 Hz and 1 kHz, the electric audiometry values in either group were recovered significantly as compared with those before treatment （all P〈0.01）. At 2 kHz, in 1 and 2 sessions of treatment, the improvements of the electric audiometry values were significant as compared with those before treatment in the acupuncture plus medication group separately （P〈0.05, P〈0.01）. At 4 kHz, the differences were not significant statistically before and after treatment in either group （all P〉0.05）. There were no abnormalities in the blood routine and liver and kidney function detections before and after treatment in either group. Conclusion Either the comprehensive therapy of electroacupuncture and western medicine or the simple western medicine comprehensive therapy is effective in the treatment of low frequency hearing damage of sudden deafness. Either of them has no effect on high frequency hearing damage. But for the middle frequency hearing damage, the efficacy of the comprehensive therapy of electroacupuncture and western medicine is superior to that of the simple western medicine comprehensive therapy.展开更多

Over the past 15 years, we have investigated the mechanisms of ischemic-induced hearing loss using a gerbil model of transient cochlear ischemia. In the gerbil, cochlear ischemia can be induced by occluding the bilateral vertebral arteries simultaneously at the neck, because the posterior communicating arteries of the Circle of Willis close spontaneously around 1 mo after birth. When 15 min ischemia was loaded on this animal, permanent hearing loss of about 25 d B and the death of hair cells, especially inner hair cells were induced. These pathological changes were mainly due to lack of an energy source, glutamate excitotoxicity, and the production of free radicals, especially superoxide and nitrous oxide species. Ischemic damage could be prevented by various procedures, such as cooling the cochlea, intratympanic administration of insulin-like growth factor 1 or AM-111(an anti-apoptotic agent), and systemic administration of prednisolone(steroid), edarabone(free radical scavenger), ginsenoside Rb1(Kanpo), hematopoietic stem cells, glia-cell derived neurotrophic factor, and liposome-encapsulated hemoglobin(artificial red blood cells). We also found that the cochlea was protected by the ischemic tolerance, indi-cating that minor cochlear ischemia alleviates or prevents inner ear damage in subsequent severe cochlear ischemia. As ISSHL usually occurs suddenly, with no preceding sign or symptom, we suggest that most ISSHL cases are caused by circulatory disturbance, probably at the stria vascularis.展开更多

Methods Twenty-eight SD cases were reviewed. In 23 cases, treatment was initiated with routine agents. Diuretic agents were later added in 8 of these cases that failed to respond to routine treatment agents. Diuretic agents were included in the initial treatment in the rest 5 cases. In total, 13 cases received diuretics in addition to routine treatment agents and 15 cases received conventional treatment only. Results In the 8 cases who received diuretics after failed conventional treatments, 4 showed hearing improvement, whereas all 5 cases in which diuretics were included in the initial treatment demonstrated hearing improvement. Conclusion These results suggest a possible role of endolymphatic hydrops in the pathophysiologic course of SD. Diuretics should be considered when clear indications exist with no conflicts to other medical conditions.展开更多

In an attempt to confirm this assumption, 10 patients with confirmed LD and 12 patients with ISD were consecutively included into the study. Further to the laboratory and audio logical investigation, a low frequency sound (LFS) stimulation on posturography was performed and evaluated. Patients with ISD had higher pure tone average (PTA) than patients with LD (PTA ISD/LD was 72 decibel (dB)/23 dB). There was no difference of vertigo between LD and ISD patients. Patients with ISD have more body sway velocity during the first stimulation than patients with LD. We conclude that the cochlear organ is more affected in ISD patients than in patients with LD. However, the vestibular organ seems to be affected in both diseases. ISD and LD are two different disease entities with different aetiologies but with common otological clinical signs.展开更多

The relative expression levels of miR-155, HDAC2, ICAM-1, TNF-α and interleukin-8 (IL-8) in PBMC of all subjects were detected by real-time fluorescence quantitative analysis (qRT-PCR). Pearson method was used to analyze the relationships between miR-155, HDAC2 and the expressions of ICAM-1, TNF-α, IL-8, and miR-155 and the expression of HDAC2 in PBMC of SSNHL patients. Logistic regression analysis was used to analyze the risk factors of SSNHL. The predictive diagnostic values of miR-155 and HDAC2 in PBMC for SSNHL were evaluated. Results:The relative expression levels of miR-155, ICAM-1, TNF-α and IL-8 in PBMC of sudden deafness group were significantly higher than those of normal group (P<0.05), while the relative expression levels of HDAC2 were significantly lower than those of normal group (P<0.05). In SSNHL patients, miR-155 were positively correlated with the expression levels of ICAM-1, TNF-α and IL-8 (P<0.05). The expression level of HDAC2 was negatively correlated with the expression levels of TNF-α and IL-8 (P<0.05). The expression level of miR-155 in PBMC of SSNHL patients was negatively correlated with HDAC2 (P<0.05). MiR-155, ICAM-1, TNF-α and IL-8 were risk factors for SSNHL (P<0.05), while HDAC2 was protective factor for SSNHL (P<0.05). The areas under curve (AUC) of miR-155 and HDAC2 in PBMC for SSNHL diagnosis were 0.855 and 0.835 respectively, the truncation values of which were 1.449 and 0.959 respectively, at this moment, the sensitivities were 75.0% and 81.3% respectively, and the corresponding specificities were 86.1% and 70.1% respectively. The AUC of combined diagnosis of SSNHL was 0.927, and the sensitivity and specificity were 86.7% and 85.3% respectively.Conclusions:The expressions of miR-155 is high and HDAC2 is low in PBMC of SSNHL patients, which are negatively correlated, and both of them may participate in the occurrence and development of SSNHL through mutual influence, which is a risk factor of SSNHL. The combination of the two can effectively improve the predictive diagnostic value of SSNHL.展开更多

We study the dynamics of IP for two-qubit X-shape states under different noisy environments. Our study shows that IP exhibits sudden change, and one side quantum channel is enough for the occurrence of a sudden change of IP. In particular, we show that the initial state having no sudden change of quantum discord exhibits a sudden change of IP under the dynamics of amplitude noise, but the converse is not true. Besides, we also investigate the dynamics of IP under two different kinds of composite noises. Our results also confirm that sudden change of IP occurs under such composite noises.展开更多

文摘Objective:To analyze the necessity and effectiveness of vestibular rehabilitation training instruction in the treatment of sudden deafness accompanied by vertigo.Methods:Sixty medical staff who learned the treatment methods for sudden deafness accompanied by vertigo(vestibular rehabilitation training)from January 2024 to February 2025 were selected as the research subjects.They were divided into two groups according to the time of study:the control group,who participated in the training teaching first,and the observation group,who participated later.Each group had 30 people.The control group received conventional training,while the observation group underwent continuous quality improvement.The effects and assessment results of different teaching methods were compared.Results:The theoretical and practical assessment scores of medical staff in the observation group were higher than those in the control group(p<0.05);the satisfaction of medical staff in the observation group with the teaching mode was higher than that in the control group(p<0.05).Conclusion:Vestibular rehabilitation training has significant effects on sudden deafness accompanied by vertigo.Training medical staff not only enhances their understanding of training methods but also enables them to provide specialized guidance to patients,improving their vertigo condition.
文摘BACKGROUND Managing sudden deafness(SD)in patients with diabetes mellitus(DM)is partic-ularly challenging due to the heightened risk of adverse effects associated with systemic drug administration.This study explores the potential of retroauricular subperiosteal injection as a localized drug delivery method for a more effective and safe treatment.AIM To compare the efficacy of retroauricular subperiosteal injection vs systemic intravenous glucocorticoid(GC)administration for SD in patients with DM and assess the effects on blood glucose levels.METHODS A total of 128 cases of type 2 DM(T2DM)with SD diagnosed and treated in Zibo Central Hospital from February 2021 to July 2023 were divided into two groups:An observation group(66 cases receiving retroauricular subperiosteal injection of methylprednisolone)and a control group(62 cases receiving systemic intravenous administration of methylprednisolone).The two groups were compared in terms of therapeutic efficacy,hearing recovery,blood glucose level changes,and incidence of adverse reactions.Binary logistic regression was used to analyze the factors affecting therapeutic efficacy.RESULTS The observation group showed a significantly higher total effective rate(90.91%)compared with the control group(75.81%,P<0.05).Additionally,pure-tone hearing threshold,fasting plasma glucose,and 2-hour postprandial blood glucose were significantly lower in the observation group compared with the control group(P<0.05).The incidence of adverse reactions was also lower in the observation group than in the control group(7.58%vs 22.58%,P<0.05).A T2DM course longer than 5 years and systemic intravenous GC administration were identified as independent risk factors for treatment inefficacy(P<0.05).INTRODUCTION Sudden deafness(SD)is a clinical emergency characterized by rapid-onset hearing loss that is often accompanied by clinical symptoms such as tinnitus and vertigo[1].Although its pathogenesis remains unclear,it is supposedly associated with factors,including inner ear microcirculation disorders,autoimmune diseases,and viral infections[2,3].Patients with diabetes are particularly susceptible to microvascular complications due to poor long-term glycemic control,affecting the ear’s microcirculation,subsequently increasing the risk of SD[4].Type 2 diabetes mellitus(T2DM),a chronic metabolic disease,causes multiple microvascular damages throughout the body,complicating SD treatment in patients with diabetes[5,6].Inner ear microcirculation disturbances in patients with diabetes may exacerbate the risk of SD,and its pathological process may be related to vascular endothelial dysfunction,inflammatory reactions,and hemorrhological changes caused by diabetes mellitus(DM)[7].Current SD treatments include glucocorticoids(GCs),vasodilators,and hyperbaric oxygen therapy[8].GCs are widely used due to their anti-inflammatory and immunosuppressive effects[9].However,systemic GCs may cause blood glucose(BG)fluctuations and even increase the risk of complications in patients with DM,limiting their clinical use in this population[10].Therefore,there is a compelling and immediate need for a local alternative solution that minimally affects the metabolic mechanisms.In recent years,retroauricular subperiosteal injection has emerged as a localized administration modality for treating SD[11].This method allows drugs to directly act on the inner ear,avoiding the side effects of systemic administration and having a minor impact on BG levels,providing a potentially effective treatment for patients with diabetes[12].However,there is limited clinical evidence to compare the efficacy and glycaemic effects of retroauricular subperiosteal injection vs systemic intravenous GC administration in patients with SD and diabetes.This study aimed to explore the efficacy of retroauricular subperiosteal injection and systemic intravenous GC administration for treating patients with SD and DM and their effects on BG,providing a safer and more effective clinical treatment approach.
文摘Objective To compare the difference in the clinical efficacy on the different frequency hearing damages for the patients with sudden deafness between the comprehensive therapy of electroacupuncture and western medicine and the simple western medicine comprehensive therapy. Methods Fifty-eight cases were randomized into an acupuncture plus medication group （28 cases, 32 damaged ears） and a western medicine group （30 cases, 34 damaged ears）. In the acupuncture plus medication group, the comprehensive therapy of electroacupuncture and western medicine was used. The main points were ěrmén （耳门 TE 21）, Tīnggōng （听宫 SI 19）, Tīnghuì （听会 GB 2）, Yìfēng （翳风 TE 17）, etc. The western medicine therapy was the comprehensive treatment with vasodilators, the medicines for promoting nerve function and releasing inner ear edema and hyperbaric oxygen. In the western medicine group, the western medicine comprehensive therapy was adopted. 10-day treatment made one session. Two sessions of treatment were required. In 1 or 2 sessions of treatment, the efficacy was observed, the electric audiometry was evaluated. Additionally, the blood routine and liver and kidney functions were detected. Results The total effective rate was 50.0% （16/32） in the acupuncture ＋ medication group and was 55.9% （19/34） in the western medicine group. The efficacies were similar between the two groups （P〉0.05）. In 1 and 2 sessions of treatment, at 250 Hz, 500 Hz and 1 kHz, the electric audiometry values in either group were recovered significantly as compared with those before treatment （all P〈0.01）. At 2 kHz, in 1 and 2 sessions of treatment, the improvements of the electric audiometry values were significant as compared with those before treatment in the acupuncture plus medication group separately （P〈0.05, P〈0.01）. At 4 kHz, the differences were not significant statistically before and after treatment in either group （all P〉0.05）. There were no abnormalities in the blood routine and liver and kidney function detections before and after treatment in either group. Conclusion Either the comprehensive therapy of electroacupuncture and western medicine or the simple western medicine comprehensive therapy is effective in the treatment of low frequency hearing damage of sudden deafness. Either of them has no effect on high frequency hearing damage. But for the middle frequency hearing damage, the efficacy of the comprehensive therapy of electroacupuncture and western medicine is superior to that of the simple western medicine comprehensive therapy.
文摘BACKGROUND Aseptic meningitis is defined as meningeal inflammation caused by various etio-logies with negative cerebrospinal fluid(CSF)bacterial culture.The most common etiologies are viruses[enteroviruses,arboviruses,and herpes simplex virus type 2(HSV-2)].Aseptic meningitis can have various presentations,including sensori-neural deafness.While sensorineural deafness from mumps meningoencephalitis has been reported,cases of HSV-2-induced hearing loss are rare.Herein,we re-port a case of HSV-2-induced meningitis that presented with sudden deafness.CASE SUMMARY A 68-year-old man experienced a profound sudden onset of left-sided hearing loss for one day.Pure-tone audiograms demonstrated sudden left-sided sensorineural hearing loss(thresholds 80-90 dB).After treatment with high-dose steroids for 1 week,he experienced an acute consciousness change with left hemiparesis.The laboratory data showed no significant abnormalities.Brain computed tomography without contrast and magnetic resonance imaging revealed no intracranial hemo-rrhage or obvious brain lesion.The CSF analysis and the Multiplex PCR panels showed HSV-2 positivity.Hence,under the diagnosis of herpes meningoenceph-alitis,acyclovir was prescribed and his symptoms gradually resolved.CONCLUSION This case report further demonstrates that a viral infection could be a cause of sudden sensorineural hearing loss.
文摘BACKGROUND To summarize the clinical characteristics of acute cerebral infarction(ACI)in patients with sudden deafness(SD)as the first symptom,improve the awareness of the disease,and help diagnosis and treatment.CASE SUMMARY From 2019 to 2020,three patients with ACI with SD as the first symptom were admitted to our hospital.Pure tone audiometry,head magnetic resonance imaging(MRI),vertebral artery and carotid artery B-ultrasound,head and neck computed tomography angiography,and other examinations were performed.Following the treatment of SD,hearing and dizziness were not significantly improved.Then,the patients developed symptoms of related cranial nerve injury,and brain MRI showed cerebral infarction in the cerebellopontine angle area.All three cases were transferred to the neurology department for relevant conservative treatment.CONCLUSION Patients with ACI with SD as the first symptom usually attend the otolaryngology clinic.Here a diagnosis of SD,which is based on an audiological examination,is made and the corresponding treatment is administered.To reduce the misdiagnosis of this disease,close attention should be paid to the changes in the patient's clinical symptoms and related auxiliary examinations should be performed,such as brain MRI and cerebrovascular imaging.Otolaryngologists should pay attention to the type and severity of hearing loss,the accompanying symptoms,age,high-risk factors for cerebral infarction,and related cranial nerve symptoms in patients with SD.If the patient's early brain MRI does not show abnormalities,monitoring remains essential.The head MRI should be analyzed quickly based on the changes in the symptoms of the patient,to make an accurate diagnosis and provide the timely and correct treatment for the patients.

文摘Objective To study concomitant symptoms and disease conditions in sudden deafness.Methods Clinical data of 418 cases of sudden deafness treated in this department from 2000 to 2007 were reviewed.Results Of the 418 cases,201 were males and 217 were females.Right ear was involved in 184 cases and left ear in 191 cases.Bilateral involvement was seen in 43 cases.The average age was 44.1 years.Tinnitus was reported in 369 cases(88.3%)either before or after hearing loss,of which 64.5%was of low pitch,27.1%of high pitch and 8.4%of mixed tones.Constant tinnitus was reported in 83%of the cases,and muffled feelings in 33.3%of the cases.Hearing loss was the only complaint in 221 cases(52.9%).Dizziness was reported in 77 cases(18.4%)and vertigo attacks in 120 cases(28%).Hypertension,coronary artery disease and diabetes were found in 19.6%of 418 cases and hyperlipidemia in 54.5%of 211 cases.CT and/or MRI data were available in 147 cases,with positive findings in 18 cases(12.3%):2 with acoustic neuroma(1.36%);4 with emphraxis in the basal ganglia,cerebellum,temporal lobe or parietal lobe,and 12 with poor pneumatization of ipsior contralateral mastoid cells.Conclusion In this case series of sudden deafness,low-pitch constant tinnitus was a common complaint.Most of the studied cases presented with simple hearing loss.Vertigo attacks were more common than dizziness in this group of patients.The most common concomitant disorder was hyperlipidemia,especially high triglycerides.Imaging studies are important in managing sudden deafness in ruling out acoustic neuroma and other intracranial diseases.
文摘Sudden deafness is one of the commonest acute symptoms in otolaryngology.In recent years,the incidence of sudden deafness is on the rise all over the world,but its etiology is still unclear,and the prognosis is greatly different.Traditional Chinese medicine(TCM)believes that the onset of sudden deafness is related to the liver,gallbladder,heart and triple energizer meridians.This article mainly explored the key points of common syndromes,TCM nursing methods and health guidance of sudden deafness.
文摘Objective To compare different treatment protocols for sudden deafness(SD),for the purpose of identifying an appropriate approach to SD.Methods A total of 104 patients with diagnosis of sudden hearing loss treated from Jan 2006 to December 2008 were included in this study,of which 31 received the typical pharmaceutical treatment(groupⅠ),40 received the typical pharmaceutical treatment plus polarized liquid(GroupⅡ)and 33 received the hyperbaric oxygen in addition to the treatment included in GroupⅡ(GroupⅢ).Results The total improvement rate(67.74%,62.50%and 75.76%for GroupsⅠ,ⅡandⅢrespectively)was not statistically different between the three groups(P>0.05).Conclusion The three treatment protocols are similar when judged by the treatment outcomes in SD,neither being superior to the others.The two important factors that appear to influence treatment outcomes are the audiogram pattern and duration of hearing loss before seeking treatment.Patients with upsloping or peak-type audiograms and treated within 7 days from the onset have better prognosis than others.
文摘The etiology of sudden deafness or idiopathic sudden sensorineural hearing loss(ISSHL) remains unclear. Over the past 15 years, we have investigated the mechanisms of ischemic-induced hearing loss using a gerbil model of transient cochlear ischemia. In the gerbil, cochlear ischemia can be induced by occluding the bilateral vertebral arteries simultaneously at the neck, because the posterior communicating arteries of the Circle of Willis close spontaneously around 1 mo after birth. When 15 min ischemia was loaded on this animal, permanent hearing loss of about 25 d B and the death of hair cells, especially inner hair cells were induced. These pathological changes were mainly due to lack of an energy source, glutamate excitotoxicity, and the production of free radicals, especially superoxide and nitrous oxide species. Ischemic damage could be prevented by various procedures, such as cooling the cochlea, intratympanic administration of insulin-like growth factor 1 or AM-111(an anti-apoptotic agent), and systemic administration of prednisolone(steroid), edarabone(free radical scavenger), ginsenoside Rb1(Kanpo), hematopoietic stem cells, glia-cell derived neurotrophic factor, and liposome-encapsulated hemoglobin(artificial red blood cells). We also found that the cochlea was protected by the ischemic tolerance, indi-cating that minor cochlear ischemia alleviates or prevents inner ear damage in subsequent severe cochlear ischemia. As ISSHL usually occurs suddenly, with no preceding sign or symptom, we suggest that most ISSHL cases are caused by circulatory disturbance, probably at the stria vascularis.
文摘Objective To study the role of diuretic agents in treating sudden deafness (SD) and explore the possibility of endolymphatic hydrops as a potential cause of SD. Methods Twenty-eight SD cases were reviewed. In 23 cases, treatment was initiated with routine agents. Diuretic agents were later added in 8 of these cases that failed to respond to routine treatment agents. Diuretic agents were included in the initial treatment in the rest 5 cases. In total, 13 cases received diuretics in addition to routine treatment agents and 15 cases received conventional treatment only. Results In the 8 cases who received diuretics after failed conventional treatments, 4 showed hearing improvement, whereas all 5 cases in which diuretics were included in the initial treatment demonstrated hearing improvement. Conclusion These results suggest a possible role of endolymphatic hydrops in the pathophysiologic course of SD. Diuretics should be considered when clear indications exist with no conflicts to other medical conditions.

文摘Objective:To analyze the efficacy of hyperbaric oxygen at different pressures in the treatment of sudden deafness.Methods:Eighty-two patients with sudden deafness treated in the Affiliated Hospital of Hebei University from September 2019 to September 2021 were selected as the research subjects.The patients were randomly divided into study group 1 and study group 2,and they were treated with hyperbaric oxygen on the basis of routine treatment,in which the pressure used was 1.8 ATA and 2.2 ATA,respectively.Oxygen was delivered via the pressure stabilizing mask for 60 minutes.The patients received two courses of treatment,each lasting 10 days.The changes in hearing(pure tone audiometry)and the clinical efficacy of both the groups were compared before and after treatment.The data obtained were statistically analyzed using SPSS 19.0.Results:The total effective rate of study group 1 was 90.00%,while that of study group 2 was 76.19%.The differences between the two groups were statistically significant(p<0.05).Conclusion:For patients with sudden deafness treated with hyperbaric oxygen,the clinical efficacy of 1.8 ATA is more significant than that of 2.2 ATA.
文摘Objective:To observe the clinical effect of hyperbaric oxygen in the treatment of sudden deafness.Methods:Ninety-six patients with sudden deafness diagnosed by the otolaryngology department were divided into 2 groups which comprised of 48 patients in the conventional treatment group and the other 48 patients in the hyperbaric oxygen treatment group.Both groups were treated with methylcobalamin,vitamin B1,and ginkgo biloba extract.The patients in the hyperbaric oxygen treatment group were given hyperbaric oxygen therapy of 2.0 ATA once a day.Each course of treatment lasted 10 days and after two courses of treatment,the clinical efficacies of the two groups were compared.Results:After two courses of treatment,the effect of treatment in the hyperbaric oxygen treatment group was significantly better than that of the conventional treatment group.Conclusion:Hyperbaric oxygen therapy can effectively improve the hearing level of patients with sudden deafness and the overall effective rate of treatment.
文摘Lyme disease (LD) and idiopathic sudden deafness (ISD) are supposed to be different diseases with different aetiologies. In an attempt to confirm this assumption, 10 patients with confirmed LD and 12 patients with ISD were consecutively included into the study. Further to the laboratory and audio logical investigation, a low frequency sound (LFS) stimulation on posturography was performed and evaluated. Patients with ISD had higher pure tone average (PTA) than patients with LD (PTA ISD/LD was 72 decibel (dB)/23 dB). There was no difference of vertigo between LD and ISD patients. Patients with ISD have more body sway velocity during the first stimulation than patients with LD. We conclude that the cochlear organ is more affected in ISD patients than in patients with LD. However, the vestibular organ seems to be affected in both diseases. ISD and LD are two different disease entities with different aetiologies but with common otological clinical signs.

文摘Background:Despite its widespread therapeutic use and effectiveness,the underlying pharmacologic mechanisms of Wendan decoction(WDD)and how it works to treat sudden deafness(SD)remain unclear.In this study,the pharmacological mechanisms of WDD underlying SD were analyzed using network pharmacology and molecular docking.Methods:The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)was employed to identify the active compounds and target genes of WDD,and genes associated with SD were screened on five databases.RGUI conducted Gene Ontology(GO)functional and the Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses.A compound-target network was established using Cytoscape,and the STRING database created a protein-protein interaction(PPI)network to identify the key compounds and targets.Subsequently,a network of crucial compound-target was generated for further molecular docking analysis.For molecular docking simulations of the macromolecular target proteins and their matching ligand molecules,AutoDock Vina and AutoDockTool were utilized.Results:TCMSP identified 162 active target genes and 36 active compounds for WDD.The active target genes were compared with the 2271 genes associated with SD to identify 70 intersecting active target genes linked to 34 active compounds.The GO functional enrichment and KEGG pathway enrichment analyses were undertaken,and compound–target,and PPI networks were built.The key compounds and protein targets were identified and integrated to form a key compound–target network.Eventually,molecular docking was performed to investigate the interactions of the protein targets with their respective compounds.Conclusion:This study highlights the mechanisms of multi-compounds,targets,and pathways of WDD acting on SD and provides further evidence of crucial compounds and their matching target proteins of WDD acting on SD.
文摘Objective To evaluate the current status of clinical studies on diagnosis and treatment of sudden deafness(SD)in China by retrospective reviewing articles on SD published in Chinese journals in the past 5 years.Special attention is given to whether the diagnosis and treatment standards established in 1996 by the otolaryngology branch of Chinese Medical Association(the'1996 standard')were followed.Methods The terms of'Sudden deafness'and'treatment'were used as the keywords in searching articles published between 2000 and 2004 in the Chinese biomedicine literature database and Chinese journal network.Principles of evidence-based medicine were applied in reviewing the articles.Results Two hundreds and thirty-four articles were identified,including 176 between 2000 and 2002 and 58 between 2003 and 2004.Among the 176 articles published between 2000 and 2002,effects of medications were studies in 126 articles,of which only 26(20.6%)followed the'1996 standards'.Eighty-nine(70.6%)were reported based on controlled clinical trials(CCT)and 36(28.5%)met the criteria of randomized controlled trails(RCT).Of the 58 articles published between 2003 and 2004,drug effects were evaluated in 25 articles,which were all based on the'1996 standards'.However,there lacked placebo control,follow-up data or statistical analysis in these papers.Only 6 articles reported side-effects from pharmacological treatment.Conclusions While a significant number of articles on SD were published in the past 5 years,the'1996 standards'were followed only in a small number of them.The standards may not be appropriate in guiding research and need to be modified for improved guidance to SD management.Multi-center,RCTs should be a crucial part in studies on SD.
文摘Objective:To investigate the expressions of microRNA-155 (miR-155) and histone deacetylase 2 (HDAC2) in peripheral blood mononuclear cells (PBMC) of patients with sudden deafness (SSNHL) and their clinical significances.Methods:112 patients with SSNHL who were treated in our hospital from February 2017 to September 2018 were selected as the study subjects, and they were referred to as sudden deafness group, and another 115 healthy examinees in the same period were compared and studied as normal group. The relative expression levels of miR-155, HDAC2, ICAM-1, TNF-α and interleukin-8 (IL-8) in PBMC of all subjects were detected by real-time fluorescence quantitative analysis (qRT-PCR). Pearson method was used to analyze the relationships between miR-155, HDAC2 and the expressions of ICAM-1, TNF-α, IL-8, and miR-155 and the expression of HDAC2 in PBMC of SSNHL patients. Logistic regression analysis was used to analyze the risk factors of SSNHL. The predictive diagnostic values of miR-155 and HDAC2 in PBMC for SSNHL were evaluated. Results:The relative expression levels of miR-155, ICAM-1, TNF-α and IL-8 in PBMC of sudden deafness group were significantly higher than those of normal group (P<0.05), while the relative expression levels of HDAC2 were significantly lower than those of normal group (P<0.05). In SSNHL patients, miR-155 were positively correlated with the expression levels of ICAM-1, TNF-α and IL-8 (P<0.05). The expression level of HDAC2 was negatively correlated with the expression levels of TNF-α and IL-8 (P<0.05). The expression level of miR-155 in PBMC of SSNHL patients was negatively correlated with HDAC2 (P<0.05). MiR-155, ICAM-1, TNF-α and IL-8 were risk factors for SSNHL (P<0.05), while HDAC2 was protective factor for SSNHL (P<0.05). The areas under curve (AUC) of miR-155 and HDAC2 in PBMC for SSNHL diagnosis were 0.855 and 0.835 respectively, the truncation values of which were 1.449 and 0.959 respectively, at this moment, the sensitivities were 75.0% and 81.3% respectively, and the corresponding specificities were 86.1% and 70.1% respectively. The AUC of combined diagnosis of SSNHL was 0.927, and the sensitivity and specificity were 86.7% and 85.3% respectively.Conclusions:The expressions of miR-155 is high and HDAC2 is low in PBMC of SSNHL patients, which are negatively correlated, and both of them may participate in the occurrence and development of SSNHL through mutual influence, which is a risk factor of SSNHL. The combination of the two can effectively improve the predictive diagnostic value of SSNHL.

文摘Quantum interferometric power(IP), a discordlike measure, plays an important role in quantum metrology. We study the dynamics of IP for two-qubit X-shape states under different noisy environments. Our study shows that IP exhibits sudden change, and one side quantum channel is enough for the occurrence of a sudden change of IP. In particular, we show that the initial state having no sudden change of quantum discord exhibits a sudden change of IP under the dynamics of amplitude noise, but the converse is not true. Besides, we also investigate the dynamics of IP under two different kinds of composite noises. Our results also confirm that sudden change of IP occurs under such composite noises.

文摘BACKGROUND Wolfram syndrome is a rare autosomal recessive genetic disorder characterized by early-onset diabetes and progressive neurodegeneration,most notably sensorineural hearing loss and optic atrophy.Because its initial manifestations are usually similar to those of type 1 diabetes,the diagnosis may be delayed until other manifestations appear.Pathogenic variations of the WFS1 gene can disrupt endoplasmic reticulum function and cellular homeostasis,but the complete mutation spectrum of WFS1 has not been fully determined.Early identification of monogenic diabetes caused by Wolfram syndrome is of vital importance,as it enables the provision of targeted multidisciplinary care and genetic counseling for affected families.CASE SUMMARY A 2-year-old Han Chinese girl was admitted with a 1-month history of polydipsia,polyuria,and polyphagia,and was diagnosed with diabetic ketoacidosis and impaired insulin secretion.Sensorineural hearing loss was also detected.Wholeexome sequencing identified a previously unreported heterozygous mutation,WFS1 c.986T>C(p.Phe329Ser),in the patient and her father,confirming the diagnosis of Wolfram syndrome.Bioinformatic analysis supported the likely pathogenicity of this mutation.In silico pathogenicity predictors(REVEL,SIFT,Poly-Phen-2,MutationTaster,and GERP+)supported a deleterious effect on wolframin structure and function.The patient was initially treated with intravenous insulin and fluid resuscitation,then transitioned to a basal–bolus insulin regimen.Glycemic control was subsequently maintained with continuous subcutaneous insulin infusion and intermittent subcutaneous injections.At the 1-and 6-month follow-ups,blood glucose remained well controlled(hemoglobin A1c:5.89%and 6.58%,respectively),with no evidence of organ dysfunction or further complications.CONCLUSION This case identifies WFS1 c.986T>C(p.Phe329Ser)as a novel pathogenic variant causing Wolfram syndrome.It highlights the importance of early genetic testing in pediatric patients with atypical diabetes presentations to enable timely diagnosis,individualized therapy,and comprehensive family support.

文摘BACKGROUND Managing refractory sudden sensorineural hearing loss(RSSHL)in patients with diabetes mellitus(DM)presents significant therapeutic challenges,highlighting the importance of identifying effective treatment strategies.AIM To analyze the therapeutic effectiveness of intratympanic injection plus retroauricular injection for RSSHL complicated with DM.METHODS This study included 84 patients with RSSHL complicated with DM from April 2021 to April 2024,all receiving routine treatment.Participants were categorized into the control group(40 cases),receiving an intratympanic injection of methylprednisolone sodium succinate(MPSS),and the research group(44 cases),treated with retroauricular MPSS injection the next day in addition to the treatment administered in the control group.The efficacy,adverse reactions(tympanic membrane perforation,middle ear infections,burning sensation,vertigo,and tinnitus),blood glucose(BG)[fasting BG(FBG),2-hour postprandial BG(2hPBG),and glycosylated hemoglobin(HbA1c)],hearing thresholds at different frequencies(250 Hz,500 Hz,and 1000 Hz),serum biochemical indexes[interleukin(IL)-6,C-reactive protein(CRP),and procalcitonin(PCT)],and quality of life assessed by the short-form 36 item health survey(SF-36)were comparatively analyzed.RESULTS The research group demonstrated a markedly higher total effectiveness rate(81.82%vs 60.00%,P=0.027)and a comparable incidence of total adverse reactions than the control group.Further,the research group exhibited notably reduced FBG,2hPBG,HbA1c,IL-6,CRP,and PCT post-treatment(P<0.01),which were lower compared with the pre-treatment levels and the control group(P<0.05),as well as reduced hearing thresholds at different frequencies(250 Hz,500 Hz,and 1000 Hz,P<0.05).Furthermore,the post-treatment SF-36 scores of the research group in terms of energy,social functioning,role functioning,physical functioning,mental health,and overall health were all significantly improved than the pre-treatment levels and the control group(P<0.05).CONCLUSION The above results indicate that intratympanic plus retroauricular injections of MPSS are effective in treating RSSHL complicated with DM without increasing the incidence of adverse reactions,which has a health promotion value.
