Analysis of the association between adiponectin, adiponectin receptor 1 and diabetic cardiomyopathy.

The aim of this study was to explore the association between adiponectin (APN), APN receptors and insulin resistance (IR) using rats with type 2 diabetes mellitus (T2DM) as a model of diabetic cardiomyopathy (DC). Serum and cardiac APN levels were assessed using a double-antibody sandwich ELISA. In addition, the mRNA and protein expression of the myocardial APN receptor 1 (AdipoR1) was determined using the reverse transcription polymerase chain reaction and immunohistochemical staining.

[A study of the pepsin in the sputum for diagnosis and treatment evaluation of laryngopharyngeal reflux].

Objective: To study the value of the pepsin in the sputum for diagnosing and evaluating the effectiveness of treatment of laryngopharyngeal reflux.

Method: Thirty-six patients with the symptoms of dry pharynx, globus pharyngeus, excessive throat clearing, chronic cough and so on were divided into laryngopharyngeal reflux group and chronic laryngitis group by the results of therapeutic trial taking proton pump inhibitors for 3 months. The estimation of the reflux symptom index (RSI), the reflux finding score (RFS) and the detection of pepsin in the sputum were done before and after the treatment.
