[Clinical analysis of 182 cases esophageal foreign bodies and treatment for special cases].

Objective: To provide clinical reference by summarizing and analyzing characteristics, therapeutic principles and methods for special cases of esophageal foreign bodies.

Method: Statistical analysis 182 cases with esophageal foreign bodies, including 41 special cases. Surgery 165 cases, 17 cases without surgery.

[Diagnosis and treatment of esophagus perforation caused by esophageal foreign bodies].

Objective: Summarize the treatment skills of esophagus perforation caused by esophageal foreign bodies.

Method: Retrospectively analyze the seven cases of esophagus foreign body perforation with various complications in our department.

Result: Six cases recovered in 3 to 18 days after operation, on average 14.

Revaluation of clopidogrel: let the data speak for themselves.

Clopidogrel was believed to be superior to aspirin by the well-known CAPRIE trial. However, no other large clinical trials demonstrated the same results, but all focused on the combination use of clopidogrel with aspirin, and combination therapy in CREDO was called the "Emperor's New Clothes". However, no one overturned the results of these clinical trials by quantitatively analyzing them.

[Modulation of gamma-aminobutyric acid receptor on medial vestibular nucleus neurons in vivo].

Objective: To investigate modulation of gamma-aminobutyric acid (GABA) and its receptors on medial vestibular nucleus neurons in vivo.

Methods: Twenty-six male Wistar rats were used. gamma-aminobutyric acid, bicuculline (BIC, gamma-aminobutyric acid A receptor antagonist) and 2-hydroxysaclofen (SAC, gamma-aminobutyric acid B receptor antagonist) were microiontophoresed on medial vestibular nucleus (MVN) neurons to determine the effects of gamma-aminobutyric acid and its antagonists on the neuronal firing rates of medial vestibular nucleus in rats in vivo.

Firing properties and classification of MVN neurons in rats.

In order to know the effects of caloric stimulation on neuronal firing in medial vestibular nuclei (MVN) by middle ear irrigation, the middle ear was irrigated with ice (4 degrees C), hot (44 degrees C), and warm (37 degrees C) water, and the firing rate of MVN neuron was extracellularly recorded. The results showed that the firing rate of MVN neuron was changed by caloric stimulation, and the majority of MVN neurons showed excitation by irrigation with hot water and inhibition by ice water (type A). The neuronal firing was recovered immediately after the cessation of the stimulation.

Influence of evoked HSP70 expression on hearing function of the cochlea in guinea pigs.

Objective: To investigate the effect of evoked heat shock protein 70 (HSP70) expression on the hearing function of the cochlea in guinea pigs.

Methods: Guinea pigs were divided into pre-exposure group (pre-treated with white noise exposure at 100 dB SPL for 45 min) and none pre-exposure group. Auditory brainstem response (ABR) thresholds were recorded at 12, 60 and 108 h after the animals in both groups were exposed to loud white noise (125 dB SPL, 90 min).
