[Electronic nose, HS-GC-MS, and relative odor activity value reveal odor differences and material basis of Glycyrrhizae Radix et Rhizoma products processed with different methods].

The Glycyrrhizae Radix et Rhizoma products processed with different methods, including raw materials(S) and products processed with honey according to the method in the Chinese Pharmacopoeia(Z) and Jianchangbang method(M), were analyzed in terms of the odor profile and volatile components by the electronic nose and headspace-gas chromatography-mass spectrometry(HS-GC-MS). The differential components in the three products were screened by chemometrics, on the basis of which the relative odor activity value(ROAV) was adopted to elucidate the odor differences among different products and the material basis of their odors. The results showed that the electronic nose effectively distinguished the products of Glycyrrhizae Radix et Rhizoma processed with different methods.

"I Sometimes Pretended to Get Groceries": Restrictive Deterrence in Drug Dealing.

Despite steady progress in drug control work, drug-related crimes are ranked third in the total number of criminal cases in China. Based on in-depth interviews with 24 offenders who are now incarcerated for drug offenses, this paper examines the strategies employed by drug offenders to evade detection and mitigate their punishment for drug dealing. Their most frequently-used strategies focus on filtering out risky people, ensuring information asymmetry and knowing when to stop.

Co-transduction of dual-adeno-associated virus vectors in the neonatal and adult mouse utricles.

Adeno-associated virus (AAV)-mediated gene transfer is an efficient method of gene over-expression in the vestibular end organs. However, AAV has limited usefulness for delivering a large gene, or multiple genes, due to its small packaging capacity (< 5 kb). Co-transduction of dual-AAV vectors can be used to increase the packaging capacity for gene delivery to various organs and tissues.

Epithelial-Mesenchymal Transition Participates in the Formation of Vestibular Flat Epithelium.

The vestibular sensory epithelium of humans and mice may degenerate into a layer of flat cells, known as flat epithelium (FE), after a severe lesion. However, the pathogenesis of vestibular FE remains unclear. To determine whether the epithelial-mesenchymal transition (EMT) participates in the formation of vestibular FE, we used a well-established mouse model in which FE was induced in the utricle by an injection of streptomycin into the inner ear.

AAV8-mediated Atoh1 overexpression induces dose-dependent regeneration of vestibular hair cells in adult mice.

Vestibular hair cells (HCs) are mechanoreceptors for the detection of head movement. Vestibular HCs of adult mammals never completely regenerate after damage, resulting in vestibular dysfunction. Overexpression of Atoh1 is effective for inducing HC regeneration.

Suggestion of a Modified Classification for Congenital Middle Ear Cholesteatoma: Based on the Clinical Characteristics and Staging of Fifty-Seven Patients.

To explore more refined classification methods of congenital middle ear cholesteatoma (CMEC) based on two existing staging systems. This study involved a retrospective data review of 57 patients (61 ears involved) with CMEC requiring the surgical treatment. Patients were classified into different stages according to Nelson, Potsic, and Modified Nelson staging system.

Cellular origin and response of flat epithelium in the vestibular end organs of mice to Atoh1 overexpression.

A flat epithelium (FE) may be found in the vestibular end organs of humans and mice with vestibular dysfunction. However, the pathogenesis of FE is unclear and inducing hair cell (HC) regeneration is challenging, as both HCs and supporting cells (SCs) in vestibular FE are damaged. To determine the cellular origin of vestibular FE and examine its response to Atoh1 overexpression, we fate-mapped vestibular epithelial cells in three transgenic mouse lines (vGlut3-iCreER:Rosa26, GLAST-CreER:Rosa26, and Plp-CreER:Rosa26) after inducing a lesion by administering a high dose of streptomycin.

Canalostomy As a Surgical Approach to Local Drug Delivery into the Inner Ears of Adult and Neonatal Mice.

Local delivery of therapeutic drugs into the inner ear is a promising therapy for inner ear diseases. Injection through semicircular canals (canalostomy) has been shown to be a useful approach to local drug delivery into the inner ear. The goal of this article is to describe, in detail, the surgical techniques involved in canalostomy in both adult and neonatal mice.

The histone deacetylase inhibitor sodium butyrate protects against noise-induced hearing loss in Guinea pigs.

Noise-induced hearing loss (NIHL) severely impacts the quality of life of affected individuals. Oxidative stress resulting from noise exposure is a significant cause of NIHL. Although histone deacetylase (HDAC) inhibitors were shown to protect against NIHL, the underlying mechanism remains unclear, and it is not known how they act on noise-induced oxidative stress.

Cochleovestibular gene transfer in neonatal mice by canalostomy.

Impairments of the inner ear result in sensorineural hearing loss and vestibular dysfunction in humans. A large proportion of these disorders are congenital, and involve both auditory and vestibular systems. Therefore, genetic interventions to correct deficits must be administered during early developmental stages.

E2F1-CDK1 pathway activation in kanamycin-induced spiral ganglion cell apoptosis and the protective effect of CR8.

Cochlear hair cell loss results in the secondary loss of spiral ganglion cells (SGCs). The death of these SGCs is due to apoptosis. The E2F1-cyclin dependent kinase 1 (CDK1) pathway is believed to represent an important mechanism of neuronal cell death.

Tumor Necrosis Factor-α-Induced Ototoxicity in Mouse Cochlear Organotypic Culture.

Tumor necrosis factor (TNF)-α is a cytokine involved in acute inflammatory phase reactions, and is the primary upstream mediator in the cochlear inflammatory response. Treatment of the organ of Corti with TNF-α can induce hair cell damage. However, the resulting morphological changes have not been systematically examined.

A review of prophylactic antibiotics use in plastic surgery in China and a systematic review.

The purpose of this study was to investigate the use of antibiotic prophylaxis for plastic surgical procedures at our hospital, and to perform a systematic literature review of randomized controlled trials evaluating the use of prophylactic antibiotics in plastic surgery. The records of patients who received plastic surgical procedures with Class I surgical incisions between 2009 and 2010 were retrospectively reviewed. A systematic literature review was conducted for studies examining the use of prophylactic antibiotics for Class I surgical wounds.

Temporospatial expression and cellular localization of VGLUT3 in the rat cochlea.

Vesicular glutamate transporter 3 (VGLUT3) plays an important role in hearing, and VGLUT3 knockout mice are deaf. However, the mechanisms whereby VGLUT3 exerts its effects in the cochlea are not well established. Elucidating the developmental and aging dynamics of VGLUT3 localization and expression in the cochlea would aid a functional understanding of auditory glutamatergic transmission.

For the sake of whom: conversation analysis of advice giving in offender counseling.

Regarded as beneficial and preferable to the clients, advice delivery has been an integral part of counseling; however, there are controversies over the suitability of giving advice in counseling services, including counseling conducted in the context of prisons. Based on conversation analysis, this article tries to explore when and how police counselors in two Chinese prisons give advice and how inmate clients respond to and seek advice in offender counseling. It is found that advice delivery, supposed to be for the inmate clients' sake, only serves a phatic function in the context of prisons in which security is a priority, and transforming inmates into law-abiding citizen is the overall goal of prison rehabilitation and correction.
