Purpose: Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are an indispensable lipid-lowering treatment option, but their cost-effectiveness has been questioned. This study aimed to perform a health economic evaluation of evolocumab versus placebo in patients with myocardial infarction (MI) in China.

Methods: A Markov cohort state-transition model was developed in decision analysis software to estimate the incremental cost-effectiveness ratio (ICER), defined as cost per quality-adjusted life-year (QALY) saved.

Obstructive Sleep Apnea Syndrome: A Preliminary Navigated Transcranial Magnetic Stimulation Study.

Nat Sci Sleep

August 2020

University of Split, School of Medicine, Department of Neuroscience, Laboratory for Human and Experimental Neurophysiology (LAHEN), Split, Croatia.

Purpose: An increase in resting motor threshold (RMT), prolonged cortical silent period duration (CSP), and reduced short-latency afferent inhibition (SAI), confirmed with previous transcranial magnetic stimulation (TMS), suggest decreased cortical excitability in obstructive sleep apnea syndrome (OSAS). The present study included MRI of OSAS patients for navigated TMS assessment of the RMT, as an index of the threshold for corticospinal activation at rest, and SAI as an index of cholinergic neurotransmission. We hypothesize to confirm findings on SAI and RMT with adding precision in the targeting of motor cortex in OSAS.

Association between Loss of Sleep-specific Waves and Age, Sleep Efficiency, Body Mass Index, and Apnea-Hypopnea Index in Human N3 Sleep.

Aging Dis

February 2020

1State Key Laboratory of Cognitive Neuroscience and Learning & IDG/McGovern Institute for Brain Research, Beijing Normal University, Beijing 100875, China.

Sleep spindles (SS) and K-complexes (KC) play important roles in human sleep. It has been reported that age, body mass index (BMI), and apnea-hypopnea index (AHI) may influence the number of SS or KC in non-rapid-eye-movement (NREM) 2 (N2) sleep. In this study, we investigated whether the loss of SS or KC is associated with the above factors in NREM 3 (N3) sleep.

Article Synopsis
  • A study was conducted to assess the effects of telemedicine on CPAP adherence in patients with obstructive sleep apnea across 17 sleep centers in Japan.
  • Patients were randomly assigned to three follow-up groups: a telemedicine group with monthly check-ins, a group with follow-ups every three months, and a group with monthly visits.
  • Results showed that the telemedicine group had noninferior adherence rates compared to the monthly follow-up group, while the three-month group did not perform as well, indicating telemedicine may be beneficial for patient adherence to CPAP therapy.

Chronic toxicity of methamphetamine: Oxidative remodeling of pulmonary arteries.

February 2020

Department of Clinical Pharmacology, School of Pharmacy, China Medical University, Shenyang, Liaoning 110122, PR China. Electronic address:

Article Synopsis
  • Methamphetamine (MA) abuse is linked to significant lung damage, particularly causing remodeling of pulmonary arteries and altering smooth muscle cell behavior in rats.
  • Chronic exposure to MA results in weight loss, increased pulmonary arterial pressure, and changes in heart structure, alongside impacting the balance between cell growth and death in pulmonary arterial smooth muscle cells (PASMCs).
  • The study suggests that Nrf2, a factor involved in antioxidant defense, is inhibited by MA, leading to oxidative stress; targeting Nrf2 could be a potential treatment strategy for lung toxicity caused by MA.

Validation of a portable monitoring device for the diagnosis of obstructive sleep apnea: electrocardiogram-based cardiopulmonary coupling.

Sleep Breath

December 2019

The Key Laboratory of Upper Airway Dysfunction-Related Cardiovascular Diseases, Beijing Institute of Heart, Lung and Blood Vessel Diseases, No. 2 Anzhen Road, Beijing, 100029, China.

Purpose: We aimed to evaluate the validity of the cardiopulmonary coupling (CPC) device, a limited-channel portable monitoring device for obstructive sleep apnea (OSA) screening in one single-center cohort, in particular in those with some cardiovascular diseases since the cardiopulmonary coupling might be different from those without.

Methods: Consecutive patients referred to the sleep medical center for assessment of possible OSA were enrolled in this study. Patients were examined with standard polysomnography (PSG) and CPC evaluation simultaneously.

Larynx squamous cell carcinoma (LSCC) is the second most aggressive head and neck squamous cell carcinoma. Numerous genes have been identified to be aberrantly expressed during the development of LSCC. However, currently, researchers focus more on the individual molecule and downstream genes, leaving the coexpression among genes and key upstream disease driver genes unexploited.

Association between serum/plasma levels of adiponectin and obstructive sleep apnea hypopnea syndrome: a meta-analysis.

Lipids Health Dis

January 2019

The Key Laboratory of Upper Airway Dysfunction-Related Cardiovascular Diseases, Beijing Institute of Heart, Lung and Blood Vessel Diseases, No. 2 Anzhen Road, Beijing, 100029, China.

Background: The relationship between obstructive sleep apnea hypopnea syndrome (OSAHS) and a variety of disease from obesity, type 2 diabetes mellitus and cardiovascular disease has been investigated previously. Reduced adiponectin levels are also associated with increased risk of these disease. However, whether serum/plasma adiponectin levels in OSAHS patients are lower than their counterparts remain controversial.

Beijing An Zhen Hospital, Capital Medical University, Key Laboratory of Upper Airway Dysfunction-related Cardiovascular Diseases, Beijing Institute of Heart Lung and Blood Vessel Disease, Beijing, China; Department of Otolaryngology-Head and Neck Surgery, Beijing An Zhen Hospital, Capital Medical University, China. Electronic address:

Objective: Obstructive sleep apnea hypopnea syndrome (OSAHS) is an independent risk factor for many clinical complications. However, how OSAHS cause multiple organ injury and initiate inter-organ communication remains unclear. Moreover, despite it is well-recognized that chronic intermittent hypoxia (CIH) is a main feature of OSAHS, specific contribution of CIH to overall OSAHS-initiated pathological complications remains unclear.

Background: The mechanism of general anesthesia (GA) has been explored for hundreds of years, but unclear. Previous studies indicated a possible correlation between NREM sleep and GA. The purpose of this study is to compare them by in vivo human brain function to probe the neuromechanism of consciousness, so as to find out a clue to GA mechanism.

The rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by dream-enacting behaviors related to the loss of the normal generalized skeletal muscle atonia during REM sleep, and shows REM sleep without atonia (RWA) during polysomnography (PSG). Patients with idiopathic RBD have been known to have a siginificantly increased risk of developing one of the α-synucleiopathies later in life, therefore the diagnosis of RBD is very important and must be dealt with carefully. A 51-year-old man was identified presenting dream-enacting behaviors and unpleasant dreams suggesting the diagnosis of RBD, in addition to snoring and excessive daytime sleepiness.
