Purpose: More than 80% of patients with moderate to severe obstructive sleep apnea (OSA) are still not diagnosed timely. The prediction model based on random forest (RF) algorithm was established by using heart rate variability (HRV), clinical and demographic features so as to screen for the patients with high risk of moderate and severe obstructive sleep apnea.
Methods: The sleep monitoring data of 798 patients were randomly divided into training set (n = 558) and test set (n = 240) in 7:3 proportion.
Background: This study aims at exploring the effect of obstructive sleep apnea-hypopnea syndrome (OSAHS) on the liver and kidney function indexes of patients and analyze the changes in these indexes after minimally invasive surgery.
Method: Patients with OSAHS ( = 51) who were diagnosed via polysomnography (PSG) and received minimally invasive surgery in the sleep disorders diagnosis and treatment center of the West China Fourth Hospital of Sichuan University from January 2017 to January 2019 were selected as test subjects and placed in the OSAHS group. At the same time, 79 healthy people with no snoring or breathing difficulties were selected from the medical examination center of the hospital as the control group (tested as normal by PSG).
Background: Allergic rhinitis is a chronic inflammatory disease with a high incidence, affecting the quality of life of patients. The aim of the present study was to explore the expression and clinical significance of vascular endothelial cell adhesion molecule-1 (VCAM-1), interleukin (IL)-6, and IL-17A in patients with allergic rhinitis.
Methods: A total of 180 patients with allergic rhinitis, who were admitted to our hospital from March 2017 to March 2020, were enrolled as the observation group.
Objective: To observe the impact of needling Neiguan (P 6) on the cardiovascular functional status in low pulse pressure syndrome.
Method: 49 eligible patients were randomly assigned to a acupuncture group with bilateral Neiguan (P 6) needled for successive 3 days, and a medication group given a daily 20 mL of Shenmai Injectio intravenously dripped for successive 6 days. The blood pressure, pulse pressure, stroke volume (SV), cardiac output(CO)/min, left ventricle work index (LVWI), mean arterial pressure (MAP), total peripheral resistance (TPR), coronary perfusion pressure (CPP), pulmonary arterial wedge pressure (PAWP), effective blood volume (BV), blood viscosity (N), microcirculation half renewal rate (MHR), and cardiac muscle blood volume (CMBV) were determined before and after the treatment, which were compared with the parameters obtained in 23 healthy subjects.
