Atrial Fibrillation Types and Chronic Kidney Disease are Independent Predictors of Atrial Fibrillation Recurrence After Radiofrequency Ablation.

Purpose: Atrial fibrillation (AF) is classified into paroxysmal, persistent, long-term persistent, and permanent types. It is commonly treated by radiofrequency ablation (RFA), which is more successful than conventional anti-arrhythmic drugs, but it is still largely unknown whether these beneficial effects are equally present for all AF types. Here, we evaluated the impact that AF type has on post-RFA patient conditions and identified underlying factors affecting AF prognoses.

[Correlation of betel nut chewing and clinicopathologic factors of oral squamous cell carcinoma].

Purpose: To investigate the correlation of clinicopathologic factors and immunophenotypic features with betel nut chewing in oral squamous cell carcinoma(OSCC).

Methods: The data of 88 patients with OSCC were collected. According to the habit of betel nut chewing, the clinicopathologic factors and immunohistochemical parameters were analyzed.

Anti-hepatitis B virus activity and hepatoprotective effect of des(rhamnosyl) verbascoside from Lindernia ruellioides in vitro.

Although clinically approved hepatitis B virus (HBV) polymerase inhibitors (lamivudine-3TC, entecavir, etc.) serve as effective therapeutics, the virus can easily generate resistance to them. Therefore, the treatment of HBV infection remains a public health problem.

Six Visual Rating Scales as A Biomarker for Monitoring Atrophied Brain Volume in Parkinson's Disease.

The focus of our investigation was to determine the feasibility of using six visual rating scales as whole-brain imaging markers for monitoring atrophied brain volume in Parkinson's disease (PD). This was a prospective cross-sectional single-center observational study. A total of 98 PD patients were enrolled and underwent an MRI scan and a battery of neuropsychological evaluations.

Analysis of Exon Dosage Using Multiplex Ligation-Dependent Probe Amplification in Chinese Patients with Early-Onset Parkinson's Disease.

Introduction: Several studies have identified a number of genes associated with Parkinson's disease (PD). Genomic rearrangements (exon dosage variations) in these genes have emerged as significant, causing mutations. However, exon dosage variations in several PD genes were rarely investigated in Chinese patients.

Fabrication and Cytotoxicity of Fucoidan-Cisplatin Nanoparticles for Macrophage and Tumor Cells.

Fucoidan, an anionic, sulfated polysaccharide from brown seaweed, is known to exhibit antitumor and immunomodulatory functions. To develop an immune protection and chemotherapeutic agent, fucoidan-cisplatin nanoparticles (FCNPs) were designed. FCNPs were prepared by mixing cisplatin with fucoidan solution or fucoidan with cisplatin solution, followed by dialysis to remove trace elements.

Mitochondrial DNA Haplogroups and the Risk of Sporadic Parkinson's Disease in Han Chinese.

Background: Mitochondrial dysfunction is linked to the pathogenesis of Parkinson's disease (PD). However, the precise role of mitochondrial DNA (mtDNA) variations is obscure. On the other hand, mtDNA haplogroups have been inconsistently reported to modify the risk of PD among different population.

[Efficacy of sublingual immunotherapy with Dermatophagoides farinae drops in preschool and school-age children with allergic asthma and allergic rhinitis].

Objective: To evaluate the efficacy of specific sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops on children with allergic asthma and allergic rhinitis of the preschool and school-age groups of children and adolescents.

Method: This study analyzed the efficacy of SLIT in 122 children (aged 3-14 yr) with house dust mites-induced allergic asthma and allergic rhinitis. According to the age, patients were defined as the preschool group ( ≤ 6 years old, n = 59) and school-age group (> 6 years old, n = 63).

Molecular analysis of SMN1, SMN2, NAIP, GTF2H2, and H4F5 genes in 157 Chinese patients with spinal muscular atrophy.

Spinal muscular atrophy (SMA) is a common and lethal autosomal recessive neurodegenerative disorder, which is caused by mutations of the survival motor neuron 1 (SMN1) gene. Additionally, the phenotype is modified by several genes nearby SMN1 in the 5q13 region. In this study, we analyzed mutations in SMN1 and quantified the modifying genes, including SMN2, NAIP, GTF2H2, and H4F5 by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), multiplex ligation-dependent probe amplification (MLPA), TA cloning, allele-specific long-range PCR, and Sanger sequencing in 157 SMA patients.

Modification of phenotype by SMN2 copy numbers in two Chinese families with SMN1 deletion in two continuous generations.

Background: As a lethal autosomal recessive hereditary disorder, childhood spinal muscular atrophy (SMA) is caused by mutations of the survival motor neuron 1 (SMN1) gene. Most of the patients died at early stage or were seriously disabled, which accounts partly for the scarcity of two continuous generations with SMA. Increasing evidence indicated that SMN2 copy number was a modifier of SMA, but in majority of sporadic patients, the bias of phenotype judgments may largely reduce the accuracy of genotype-phenotype analysis.

Rapid diagnosis of spinal muscular atrophy using high-resolution melting analysis.

Background: Spinal muscular atrophy (SMA) is an autosomal recessive hereditary disorder caused by mutations of the survival motor neuron 1 (SMN1) gene. Recently, high-resolution DNA melting analysis (HRMA) with saturation LC Green dyes has become a powerful post-PCR technique for genotyping or mutation scanning. So far, no studies have applied HRMA to the molecular analysis of SMA.
