Agreement of corneal curvature and central corneal thickness obtained from a swept-source OCT and Pentacam in ectopia lentis patients.

Aim: To assess the inter-device consistency of corneal curvature and central corneal thickness between Pentacam and a swept-source Fourier-domain anterior segment optical coherence tomography (AS-OCT) in ectopia lentis patients.

Methods: Totally 72 eyes of ectopia lentis patients were recruited. Central corneal thickness (CCT), corneal curvature values and corneal astigmatism were obtained from both the Pentacam and AS-OCT (CASIA2).

Rational design of secondary operation for penetrating head injury: A case report.

Penetrating head injury is rare, and thus management of such injuries is non-standard. Early diagnosis and intraoperative comprehensive exploration are necessary considering the complexity and severity of the trauma. However, because of the lack of microsurgical techniques in local hospitals, the possible retained foreign bodies and other postoperative complications such as cerebrospinal fluid (CSF) leak usually require a rational design for a secondary operation to deal with.

Expertise-Level-Dependent Functionally Plastic Changes During Motor Imagery in Basketball Players.

Motor imagery is the mental process of rehearsing or simulating a given action without overt movements. The aim of the present study is to examine plastic changes in relevant brain areas during motor imagery with increasing expertise level. Subjects (novices, intermediate and elite players) performed motor imagery of basketball throws under two experimental conditions (with-ball and without-ball).

Morphological and Functional Differences between Athletes and Novices in Cortical Neuronal Networks.

The cortical structural and functional differences in athletes and novices were investigated with a cross-sectional paradigm. We measured the gray matter volumes and resting-state functional connectivity in 21 basketball players and 21 novices with magnetic resonance imaging (MRI) techniques. It was found that gray matter volume in the left anterior insula (AI), inferior frontal gyrus (IFG), inferior parietal lobule (IPL) and right anterior cingulate cortex (ACC), precuneus is greater in basketball players than that in novices.

[Level of glutamate on the auditory pathway of inferior colliculus after exposure to noise observed by microdialysis in vivo].

Objective: To explore the quality and quantity of glutamate(Glu) on the auditory pathway of inferior colliculus when exposed to conditioning noise or traumatic sound to find the relationship between the change of neurotransmitters and the protection of hearing, and the mechanism in the phenomena.

Methods: Twenty Sprague-Dawley rats were divided into four groups: control group, conditioning group, intensive noise group and combining group. The hearing function was measured by ABR.

[Expression of antisecretory factor and aquaporin 1, 2 in the rat inner ear and their interaction].

Objective: To study the interaction among aquaporin1 (AQP), aquaporin2 (AQP2) and antisecretory factor( AF) , and their expression in the rat inner ear for furthur understanding of Meniere' s disease.

Methods: Inner ear tissue section of six healthy male Sprague-Dawley rats was performed and Envision immunochemical staining was applied to detect the expression of AF, AQP1 and AQP2 in the rat inner ear. Vestibular and cochlear tissues of twenty healthy male Sprague-Dawley rats were dissected.

Effects of caloric vestibular stimulation on serotoninergic system in the media vestibular nuclei of guinea pigs.

Background: Anatomic and electrophysiological studies have revealed that the neurons located in the media vestibular nuclei (MVN) receive most of the sensory vestibular input coming from the ipsilateral labyrinth and the responses of MVN neurons to caloric stimulation directly reflect changes in primary vestibular afferent activity. The aim of this study was to clarify the intrinsic characteristics of serotonin (5-hydroxytryptamine, 5-HT) release in the MVN during the period of vertigo induced by caloric stimulation.

Methods: We used an in vivo microdialysis technique to examine the effects of caloric stimulation on the serotoninergic system in MVN.

[Inhibition of salicylate on potassium channels in rat inferior colliculus neurons].

Objective: To understand what role of the transient outward potassium channels and the delayed rectifier potassium channels play in the mechanism of salicylate-induced tinnitus.

Methods: The effects of salicylate on the transient outward potassium channels and the delayed rectifier potassium channels in freshly dissociated inferior colliculus neurons of rats were studied, using the whole-cell voltage clamp method.

Results: Salicylate blocked the transient outward potassium current (I(K(A and the delayed rectifier potassium current (I(K(DR in concentration-dependent manner (0.

[Expression of adrenomedullin in the tissue with laryngeal carcinoma].

Objective: To observe the expression of adrenomedullin (AM) in the patients with laryngeal carcinoma.

Methods: Two-step immunohistochemistry method was used to examine the expression of AM in the patients with laryngeal carcinoma. Radioimmunoassay was applied to determine the concentration of AM in the laryngeal carcinoma tissues, adjacent laryngeal mucosa of carcinoma tissues and in the plasma of patients and controls.

[Stem cell characteristics of human fetal articular cartilage-derived cells].

Objective: To verify the hypothesis that cells with characteristics similar to bone marrow mesenchymal stem cells(MSCs) can be isolated and cultured from human fetal articular cartilage.

Methods: Human fetal articular cartilages were harvested from fetuses aborted between 12 and 20 weeks. Cells were grown in monolayer cultures in IMDM medium containing antibiotics, L-glutamine and fetal calf serum.

[Study of neurological mechanism of lidocaine's suppression to tinnitus via microdialysis].

Objective: To elucidate the neurological mechanism of lidocaine's suppression to tinnitus.

Methods: Thirty-four Wistar rats weighing 300-350 grams were randomly divided into IC group (n = 17) and AC group (n = 17), according to microdialysis region. Each group was randomly subdivided into saline treatment group (n = 4), salicylate treatment group (n = 6), and salicylate + lidocaine treatment group (n = 7).

[Intra-arterial thrombolysis for the treatment of restricted cochlear microcirculation disorder in guinea pigs].

Objective: To ascertain a new treatment method for restricted cochlear microcirculation disorder.

Methods: Photochemical reaction was utilized to induce localized microcirculation damage to the second cochlear turn of every guinea pig. The animals were divided into 5 groups.
