Dear Editor,Afferent synapses of cochlear inner hair cells(IHCs)employ a unique molecular machinery(see extended background in Supplementary Materials).Otoferlin is a key player in this machinery and its defects cause human auditory synaptopathy(Moser and Starr,2016).Otoferlin,a tail-anchored(Vogl et al.,2016)multi-C_(2)-domain protein(Fig.1Ai)specific to hair cells(Roux et al.,2006),is a member of the ferlin protein family involved in membrane trafficking and repair that are of major disease relevance(Pangršičet al.,2012),also see Supplementary *** is distributed broadly within IHCs(Fig.2Ai-Aiii;Pangrsic et al.,2010;Roux et al.,2006).

AIM： To evaluate the feasibility of a new clinical rating scale for a standardized assessment of cirrhosis-associated neuro-psychiatric symptoms. METHODS： Forty patients with liver cirrhosis （LC, with or without low-grade hepatic encephalopathy） were investigated using a clinical neuro-psychiatric rating scale based on a comprehensive list of neurological, psychomotor, cognitive, affective, behavioral symptoms, and symptoms of disturbed bioregulation. RESULTS： The analysis revealed that the majodty of cirrhotic patients showed, besides characteristic neurological symptoms of hepatic encephalopathy, various psychomotor, affective and bioregulatory symptoms （disturbed sleep and sexual dysfunction）. Patients were impaired in the following subscales： sleep and biorhythm disorder （75.0% of patients）, Parkinsonoid symptoms （25.0%）, affective symptoms （17.5%）, and psychomotor retardation （12.5%）. The increase of total neuro-psychiatric clinical score was significantly associated with the degree of hepatic encephalopathy. CONCLUSION： This study suggests that a substantial number of patients with LC and low-grade hepatic encephalopathy manifest various clinical neuro-psychiatric symptoms. The use of a rating scale, which explores clinical dimensions of hepatic encephalopathy, would improve the management of patients with LC.
