A novel dynamic membrane-equipped element sulfur-based denitrification reactor for efficient and easily maintainable treatment of high-nitrate wastewater.

Using powdered sulfur (S) with high specific surface area enables high efficiency in an elemental sulfur-based denitrification (ESDeN) reactor but faces challenges with S retention. While integrating the ESDeN process with microfiltration membranes (MM) has been shown to effectively reject S powder, severe membrane fouling and high membrane costs restrict its practical application. This study, for the first time, reports a dynamic membrane-equipped ESDeN (ESDeN-DM) reactor.

Reduced DTI-ALPS index in tinnitus patients: DTI-ALPS as a mediator of sleep on tinnitus.

Background: Sleep disturbance is a common comorbidity in tinnitus patients, which may be attributed to changes in brain structure and function. The aim of this study was to explore the potential role of the glymphatic system (GS), a recently discovered pathway for brain waste clearance, in tinnitus and the associated sleep disturbance.

Methods: The DTI-ALPS index of 22 tinnitus patients and 22 healthy controls (18-60 years old) were compared after controlling for age, sex, and handedness.

Analysis of Studies in Tinnitus-Related Gene Research.

Objective: Summarize and analyze the current research results of tinnitus-related genes, explore the potential links between the results of each study, and provide reference for subsequent studies.

Methods: Collect and sort out the research literature related to tinnitus genes included in PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang Data Knowledge Service Platform before December 31, 2019. Then the relevant contents of the literature were sorted out and summarized.

Etiology of newborn hearing impairment in Guangdong province: 10-year experience with screening, diagnosis, and follow-up.

Background: Hearing impairment is one of the most common birth defects in children. Universal newborn hearing screenings have been performed for 19 years in Guangdong province, China. A screening/diagnosis/intervention system has gradually been put in place.

Effect of balloon dilation eustachian tuboplasty combined with tympanic tube insertion in the treatment of chronic recurrent secretory otitis media.

Purpose: To investigate the long-term clinical effect of balloon dilation eustachian tuboplasty (BET) combined with tympanic tube insertion (TTI) in the treatment of chronic recurrent secretory otitis media (CRSOM).

Materials And Methods: A retrospective study of 30 cases of CRSOM treated with BET combined with TTI under general anesthesia between August 2014 and September 2016. Thirty cases of CRSOM treated with TTI in the same period were taken as the control group.

[Vertigo due to enlarged vestibule with lateral semicircular canal dysplasia: an analysis of clinical characteristics].

Objective: To explore the clinical characteristics and possible pathological mechanisms of vertigo due to enlarged vestibule with lateral semicircular canal dysplasia.

Methods: A retrospective review was conducted for 5 cases of peripheral vertigo due to enlarged vestibule with lateral semicircular canal dysplasia. Their characteristics of medical history, precipitating factors, course of vertigo, auditory tests, vestibular tests and imaging examine results were analyzed.

[The clinical characteristics of the benign paroxysmal positional vertigo associated with Meniere's disease].

Objective: To explore the clinical characteristics of the benign paroxysmal positional vertigo (BPPV) associated with Meniere's disease (MD) in retrospect in an effort to improve the diagnosis and efficacy of treatment.

Method: Fifteen cases (1 male and 14 female, aged 46 to 68 years old) of BPPV associated with MD from July 2007 to June 2009 were retrospectively analyzed. Patient clinically characterized with positional paroxysmal vertigo were diagnosed as MD by ECochG and glycerol test and were confirmed as BPPV associated with MD by Dix Hallpike test or roll test.

[Chronic tinnitus: a grading management mode study].

Objective: To probe into grading management mode for chronic tinnitus victims, so as to improve the cost-effectiveness rate of tinnitus treatment.

Methods: According to the severity of patient's own feeling and the therapy demand, the authors managed 587 of chronic tinnitus victims using a progressive methods: Level 1 was primary evaluation, counseling and treatment for tinnitus victims, then determined if the victim require further clinical intervention. Level 2 was educational counseling about the knowledge of tinnitus.

[Acute aggravation of chronic tinnitus: a study of the hearing characteristic and prognosis].

Objective: To investigate the hearing change when chronic tinnitus acute aggravated and the affect of prognosis due to hearing change.

Methods: The pure tone threshold and acoustic immittance were used for every case in the acute aggravation of chronic tinnitus (AACT) group, and for some of AACT group members the auditory brainstem response (ABR), distort-product otoacoustic emission (DPOAE), electrocochleogram (EcochG), glycerin test and MRI were used at the same time for further diagnosis. For the chronic tinnitus, the patients accepted the intervention of tinnitus retraining therapy (TRT) both for the AACT group and the control group.
