Background: The purpose of this research is to study the sonographic and clinicopathologic characteristics that associate with axillary lymph node metastasis (ALNM) for pure mucinous carcinoma of breast (PMBC).

Methods: A total of 176 patients diagnosed as PMBC after surgery were included. According to the status of axillary lymph nodes, all patients were classified into ALNM group (n = 15) and non-ALNM group (n = 161).

Background: The bimodal balance-recovery model predicts that corticospinal tract (CST) integrity in the affected hemisphere influences the partterns of brain recovery after stroke. Repetitive transcranial magnetic stimulation (rTMS) has been used to promote functional recovery of stroke patients by modulating motor cortical excitability and inducing reorganization of neural networks. This study aimed to explore how to optimize the efficiency of repetitive transcranial magnetic stimulation to promote upper limb functional recovery after stroke according to bimodal balance-recovery model.

Background: Papillary thyroid cancer (PTC) has a strong propensity to metastasize to the cervical lymph nodes. Little was known currently about whether tumor's location would influence the risk of lymph node metastasis in PTC.

Methods: The study enrolled PTC patients who underwent primary surgical therapy in our center for small unifocal tumor.

Protocadherin 11X (Pcdh11X) has been suspected to be associated with Alzheimer's disease through participating in the metabolism of PP1α and β-catenin or by altering the synaptic functions. A recent genome-wide association study reported that a common single nucleotide polymorphism (SNP, rs5984894) in the gene encoding Pcdh11X was associated with susceptibility to late-onset Alzheimer's disease (LOAD) in Caucasians. In order to assess the involvement of the PCDH11X polymorphism in the risk of developing AD in Chinese, we analyzed the genotype and allele distributions of the PCDH11X rs5984894 polymorphism in a Han Chinese population (355 LOAD cases and 399 healthy controls).

Background: Clusterin (also called apolipoprotein J) has a potential central role in the pathogenesis of Alzheimer's disease (AD). Recently, two genome-wide association studies have identified three variants in CLU gene encoding clusterin associated with AD risk in Caucasians, while there are no studies on the association of CLU with AD risk in Asians.

Methods: The study investigated 324 sporadic late-onset AD (LOAD) and 388 healthy controls matched for sex and age in a Han Chinese population.

The amyloid beta-protein (Abeta)-induced complement system activation plays an important role in Alzheimer's disease (AD). Complement receptor 1 (CR1) is thought to contribute to Abeta clearance. A recent large genome-wide association study (GWAS) has identified significant association of two single nucleotide polymorphisms (SNPs) (rs6656401 and rs3818361) in the CR1 gene with AD in Caucasians.

From the roots of Ligularia macrophylla, a bisesquiterpene, ligumacrophyllal (1), and an eremophilane sesquiterpene, ligumacrophyllatin (2) were isolated. Their structures were elucidated by 2D-NMR herein. Additionally, seven known compounds (3-9) were afforded from the plant, and compound 3 was found as natural product for the first time.
