The Median Effective Dose of Dexmedetomidine for the Inhibition of Emergence Delirium in Preschool Children Undergoing Tonsillectomy and/or Adenoidectomy: A Retrospective Dose-response Trial.

The incidence of emergence delirium (ED) is higher in preschool children undergoing tonsillectomy and/or adenoidectomy. The purpose of this study was to determine the median effective dose (ED50) of dexmedetomidine (DEX) for the inhibition of ED in preschool children by using probit regression analysis. A total of 140 anesthesia records were retrieved and divided into seven groups based on the infusion rate of DEX: .

4,8-Dicarboxyl-8,9-iridoid-1-glycoside inhibits apoptosis in human osteoarthritis chondrocytes via enhanced c-MYC-mediated cholesterol metabolism in vitro.

Background: Osteoarthritis (OA) is a degenerative disease related to cholesterol metabolism disorders. However, current therapies for OA are insufficient and no convincing disease-modifying OA drugs exist. Therefore, we aimed to elucidate the mechanism by which borojoa iridoid glycoside (BIG) inhibits chondrocyte apoptosis in OA.

Thyrotroph embryonic factor polymorphism predicts faster progression of Parkinson's disease in a longitudinal study.

The thyrotroph embryonic factor gene is a circadian clock-controlled gene. The rs738499 polymorphism of this gene has been suggested to be associated with depression and sleep disturbance in Parkinson's disease in previous cross-sectional studies. We aimed to investigate whether this single nucleotide polymorphism is associated with the progression rates of various motor and non-motor symptoms in patients with Parkinson's disease.

Comparison of Three Motor Subtype Classifications in Parkinson's Disease Patients.

The aims of this study were to compare the characteristics of three motor subtype classifications in patients with Parkinson's disease (PD) and to find the most suitable motor subtype classification for identifying non-motor symptoms (NMSs). According to previous studies, a total of 256 patients with PD were classified using the tremor-dominant/mixed/akinetic-rigid (TD/mixed/AR), TD/indeterminate/postural instability and gait disturbance (PIGD), and predominantly TD/predominantly PIGD (p-TD/p-PIGD) classification systems. Among the TD/mixed/AR subgroups, the patients with the AR subtype obtained more severe motor scores than the patients with the TD subtype.

Identification of microRNAs for the early diagnosis of Parkinson's disease and multiple system atrophy.

MicroRNAs are reportedly involved in the pathogenesis of neurodegenerative diseases, including Parkinson's disease and multiple system atrophy. We previously identified 7 differentially expressed microRNAs in Parkinson's disease patients and control sera (miR-30c, miR-31, miR-141, miR-146b-5p, miR-181c, miR-214, and miR-193a-3p). To investigate the expression levels of the 7 serum microRNAs in Parkinson's disease and multiple system atrophy, 23 early Parkinson's disease patients (who did not take any anti- Parkinson's disease drugs), 23 multiple system atrophy patients, and 24 normal controls were recruited at outpatient visits in this study.

Validation of Revised Chinese Version of PD-CRS in Parkinson's Disease Patients.

There is a high prevalence of mild cognitive impairment (MCI) and dementia in Parkinson's disease (PD) patients, but a Chinese version of cognitive rating scale that is specific and sensitive to PD patients is still lacking. The aims of this study are to test the reliability and validity of a Chinese version of Parkinson's disease-cognitive rating scale (PD-CRS), establish cutoff scores for diagnosis of Parkinson's disease dementia (PDD) and PD with mild cognitive impairment (PD-MCI), explore cognitive profiles of PD-MCI and PDD, and find cognitive deficits suggesting a transition from PD-MCI to PDD. PD-CRS was revised based on the culture background of Chinese people.

Cognitive impairment in patients with Parkinson's disease: A 30-month follow-up study.

Objective: A longitudinal (30-month) study of the cognitive changes in Parkinson's disease patients and analysis of influencing factors.

Methods: The cognitive function and related symptoms of 102 patients with idiopathic Parkinson's disease were assessed using the Montreal Cognitive Assessment (MoCA), Mini-Mental State Examination (MMSE), and relevant scales, at baseline and 30-month follow-up. The t-test, nonparametric tests, and regression analyses were used to evaluate cognitive decline and investigate risk factors for cognitive impairment.

A panel of four decreased serum microRNAs as a novel biomarker for early Parkinson's disease.

Context: Sensitive, non-invasive biomarkers that facilitate Parkinson's disease (PD) detection and stage assignment are currently unavailable.

Objective: The objective of this study is to investigate the potential of circulating microRNAs (miRNAs) as novel biomarkers for PD.

Materials And Methods: Solexa sequencing technology and quantitative real-time PCR were applied to screen and verify altered serum miRNAs in PD patients.

The Natural History of Depression in Parkinson's Disease within 30-Month Follow-Up.

Depression is one of the most common and persistent nonmotor syndromes occurring in 35% of patients diagnosed with PD. However, little information is known about the longitudinal study of its natural history of depression in PD. In this study, we identified 110 patients who are diagnosed with idiopathic PD and recruited them for assessing information about their PD related motor and nonmotor symptoms and rating scales.

Using the Montreal Cognitive Assessment Scale to screen for dementia in Chinese patients with Parkinson's Disease.

Background: Dementia is one of the most distressing and burdensome health problems associated with Parkinson's Disease (PD). The Montreal Cognitive Assessment scale (MoCA) is widely used to screen for dementia in PD patients, but the appropriate diagnostic cutoff score when used with Chinese PD patients is not known.

Aim: Determine a diagnostic cutoff value of the Chinese version of the MoCA (MoCA-C) for Chinese PD patients and describe the characteristics of PD patients screened positive for dementia using the MoCA-C.
