Lack variation of low slow-wave activity over time in the frontal region in NREM sleep may be associated with dyskinesia in Parkinson's disease.

Objective: Levodopa-induced dyskinesia (DYS) adversely affects the quality of life of Parkinson's disease (PD) patients. However, few studies have focused on the relationship between DYS and sleep and electroencephalography (EEG). Our study aimed to establish the objective physiological indicators assessed by polysomnography (PSG) that are associated with DYS in PD patients.

Survival and prognostic factors for patients with malignant central airway obstruction following airway metallic stent placement.

Background: There have been many studies on the effectiveness and complications of airway stent, but few had focused on factors that affect survival after stent placement. This study intended to assess the factors associated with the survival in patients with malignant central airway obstruction (MCAO) after airway metallic stent placement.

Methods: The clinical data of adult MCAO patients who underwent stent placement form February 2003 to June 2017 in the First Affiliated Hospital of Soochow University in China were retrospectively analyzed.

Serum cystatin C levels are negatively correlated with post-stroke cognitive dysfunction.

Stroke is the leading cause of death and long-term disability worldwide, and cognitive impairment and dementia are major complications of ischemic stroke. Cystatin C (CysC) has been found to be a neuroprotective factor in animal studies. However, the relationship between CysC levels and cognitive dysfunction in previous studies has revealed different results.

Poor nighttime sleep is positively associated with dyskinesia in Parkinson's disease patients.

Background: Dyskinesia is a troublesome complication of long-term dopaminergic medications in Parkinson's disease (PD) patients. Many factors are reported to be associated with dyskinesia in PD.

Objective: To investigate the association between sleep quality and dyskinesia in patients with PD.

Serum sodium and chloride are inversely associated with dyskinesia in Parkinson's disease patients.

Objective: We aim to report and evaluate the associations between serum sodium and chloride and dyskinesia in patients with Parkinson's disease. One hundred and two patients with Parkinson's disease were enrolled in this study.

Methods: Patients' serum electrolytes including sodium, calcium, potassium, magnesium, and chloride were measured.

Combined Effects of Family History of Cardiovascular Disease and Serum C-reactive Protein Level on the Risk of Stroke: A 9.2-year Prospective Study among Mongolians in China.

Objective: We aimed to evaluate the combined effect of a family history of cardiovascular disease (CVD) and high serum C-reactive protein (CRP) on the stroke incidence in an Inner Mongolian population in China.

Methods: A prospective cohort study was conducted from June 2002 to July 2012, with 2,544 participants aged 20 years and over from Inner Mongolia, China. We categorized participants into four groups based on the family history of CVD and CRP levels.

Vitamin D Deficiency in Relation to the Risk of Metabolic Syndrome in Middle-Aged and Elderly Patients with Type 2 Diabetes Mellitus.

Vitamin D deficiency is highly prevalent all over the world and dietary intakes of vitamin D are very low in China. In this study we aimed to determine whether vitamin D deficiency is associated with increased risk of metabolic syndrome (MetS) among Chinese type 2 diabetes mellitus (T2DM) patients aged over 50 y. Serum 25-hydroxyvitamin D [25(OH)D] concentrations were measured in a cross-sectional sample of 270 T2DM patients aged over 50 y from Zhejiang.

C-reactive Protein Level, Apolipoprotein B-to-apolipoprotein A-1 Ratio, and Risks of Ischemic Stroke and Coronary Heart Disease among Inner Mongolians in China.

Objective: We aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1 (ApoB/ApoA-1) ratio on the incidence of ischemic stroke (IS) or coronary heart disease (CHD) in a Mongolian population in China.

Methods: From June 2003 to July 2012, 2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation. All the participants were divided into four subgroups according to C-reactive protein (CRP) level and ApoB/ApoA-1 ratio.

Overweight, resting heart rate, and prediabetes/diabetes: A population-based prospective cohort study among Inner Mongolians in China.

We aimed to investigate the cumulative effect of overweight and resting heart rate on prediabetes/diabetes incidence in an 10-year follow-up study in Inner Mongolians. Among 1729 participants who were free from prediabetes and diabetes at baseline, 503 and 155 subjects developed prediabetes and diabetes, respectively. We categorized the participants into 4 subgroups according to overweight and resting heart rate status.

Measures of Abdominal Adiposity and Risk of Stroke: A Dose-Response Meta-analysis of Prospective Studies.

Objective: Waist circumference, waist-to-hip ratio and waist-to-height ratio, which are the indicators or measures of abdominal adiposity, have long been hypothesized to increase the risk of stroke; yet evidence accumulated till date is not conclusive. Here, we conducted a dose-response meta-analysis to summarize evidences of the association between these measures of abdominal adiposity and the risk of stroke.

Methods: PubMed and Web of Science databases were searched from inception to May 2015.
