Sox9 Promotes Cardiomyocyte Apoptosis After Acute Myocardial Infarction by Promoting miR-223-3p and Inhibiting MEF2C.

Acute myocardial infarction (AMI) is a severe and even fatal cardiovascular disease. The effect of transcription factors on AMI is intensively explored. Our experiment attempts to probe the role of Sox9 in cardiomyocyte apoptosis after AMI.

[Analysis of the factors for the lymph node metastasis in rⅥb region of thyroid micropapillary carcinoma and the application value of intraoperative nano-carbon].

To investigate the relationship between lymph node metastasis in rⅥb region and pathological features of papillary thyroid microcarcinoma, and the application value of carbon nanoparticles in the operation for lymph node dissection in rⅥb region. One hundred and seventy-five patients were divided into carbon nanoparticles group and the control group depending on whether carbon nanoparticles were used in the operation. The operation time, the number of central lymph node, the number of rⅥb region lymph node, hypocalcaemia symptom complex and hoarseness after the operaion were compared between the two groups.

[The evaluation of nasal ventilatioan in patients with obstructive sleep apnea-hypopnea syndrome after nasal cavity ventilation expansion techniques by using acoustic rhinometry].

Objective: To evaluate nasal ventilation in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) after nasal cavity ventilation expansion techniques by using acoustic rhinometry.

Method: Thirty-eight patients with mild OSAHS and 17 patients with moderate OSAHS who were diagnosis by PSG were selected. The acoustic rhinometry and rhinomanometry were used to assess the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) before and after the surgery (6 month later).

[The evaluation of nasal ventilation in allergic rhinitis patients after nasal provocation].

Objective: To evaluate nasal ventilation in allergic rhinitis patients after nasal provocation with acoustic rhinometry.

Method: Twenty AR cases were selected. Each one was assessed for the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) by using acoustic rhinometry before and after nasal provocation 1 hour and 6 hours later.

Properties and functions of KATP during mouse perinatal development.

Background: Prevailing data suggest that ATP-sensitive potassium channels (K(ATP)) contribute to a surprising resistance to hypoxia in mammalian embryos, thus we aimed to characterize the developmental changes of K(ATP) channels in murine fetal ventricular cardiomyocytes.

Methods: Patch clamp was applied to investigate the functions of K(ATP). RT-PCR, Western blot were used to further characterize the molecular properties of K(ATP) channels.
