[Research Progress in the Relationship Between Neurofilament Light Chain Protein and Cognitive Impairment in Type 2 Diabetes Mellitus].

Metabolic abnormality in type 2 diabetes mellitus(T2DM)can cause damage to the central nervous system,leading to cognitive decline.Neurofilament light chain protein(NFL),as a blood marker of neuroaxonal injuries,is significantly associated with the onset of cognitive impairment and affected by the renal function.It can participate in the development of cognitive impairment in T2DM through inflammation,blood-brain barrier breakdown,interaction between microglia and neurons,and Tau protein phosphorylation.

[Research Progress in the Role of Tamoxifen in Nervous System and Cognitive Function].

Neurological diseases include a variety of neurodegenerative diseases and other brain damage diseases.The treatment schemes for neurological diseases are still in research.The existing clinical and basic studies have confirmed that traditional estrogen therapy has certain protective effect on the nervous system,while it increases the risk of breast or endometrial cancer.

Expression, Prognostic Value, and Functional Mechanism of Polarity-Related Genes in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is a common malignant tumor with high mortality and poor prognoses around the world. Within-cell polarity is crucial to cell development and function maintenance, and some studies have found that it is closely related to cancer initiation, metastasis, and prognosis. The aim of our research was to find polarity-related biomarkers which improve the treatment and prognosis of HCC.

MicroRNA expression profiles related to early stage murine concanavalin A-induced hepatitis.

Background: Fulminant hepatitis is a severe liver disease characterized by massive hepatocyte necrosis and clinical signs of liver failure. This study explores the expression profile of microRNAs, which are regulators of a number of pathophysiological processes, during the early stage of concanavalin A (Con A)-induced hepatitis.

Methods: Balb/c mice were given ConA injections to induce fulminant hepatitis.

A microarray analysis of early activated pathways in concanavalin A-induced hepatitis.

Objective: To explore the mechanisms of fulminant hepatitis (FH) in the early stages, and to determine the critical pathways in its initiation and progression.

Methods: Twelve BALB/c mice were divided into four groups: one group left as negative control and sacrificed immediately after injection of phosphate-buffered saline (PBS), and another three groups with concanavalin A (Con A) administration sacrificed at 1, 3, and 6 h after injection.

Using oligonucleotide suspension arrays for laboratory identification of bacteria responsible for bacteremia.

The aim of this study was to develop and validate an oligonucleotide suspension array for rapid identification of 15 bacterial species responsible for bacteremia, particularly prevalent in Chinese hospitals. The multiplexed array, based on the QIAGEN LiquiChip Workstation, included 15 oligonucleotide probes which were covalently bound to different bead sets. PCR amplicons of a variable region of the bacterial 23S rRNA genes were hybridized to the bead-bound probes.

[Identification of closely related bacteria via phylogenetic methods].

Objective: To differentiate closely related pathogenic bacteria via phylogenetic method on the basis of gyrB gene sequences.

Methods: GyrB sequences of 19 strains of E.coli, 13 Shigella spp.

[Classification and identification of vibrio cholerae and vibrio parahaemolyticus isolates based on gyrB gene phylogenetic analysis].

In order to validate the usefulness of gyrB genotype for the classification and identification of Vibrio cholerae and Vibrio parahaemolyticus isolates, the phylogenetic analysis of 13 V. cholerae, 8 V. parahaemolyticus, 2 Aeromonas hydrophila and 1 Plesiomonas shigelloides strains was carried out using the partial coding sequence of gyrB, a gene that encodes the B subunit of DNA gyrase (topoisomerase type II ) in bacteria.
