Plasma Quantitative Lipid Profiles: Identification of CarnitineC18:1-OH, CarnitineC18:2-OH and FFA (20:1) as Novel Biomarkers for Pre-warning and Prognosis in Acute Myocardial Infarction.

This study was aimed to determine the association between potential plasma lipid biomarkers and early screening and prognosis of Acute myocardial infarction (AMI). In the present study, a total of 795 differentially expressed lipid metabolites were detected based on ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Out of these metabolites, 25 lipid metabolites were identified which showed specifical expression in the AMI group compared with the healthy control (HC) group and unstable angina (UA) group.

Construction of tissue-engineered lymphatic vessel using human adipose derived stem cells differentiated lymphatic endothelial like cells and decellularized arterial scaffold: A preliminary study.

We have previously demonstrated that human adipose-derived stem cells (hADSCs) can be differentiated into lymphatic endothelial like cells. The purpose of this study was to investigate the feasibility of utilizing the induced lymphatic endothelial like cells and decellularized arterial scaffold to construct the tissue-engineered lymphatic vessel. The hADSCs were isolated from adipose tissue in healthy adults and were characterized the multilineage differentiation potential.

In vitro induction of human adipose-derived stem cells into lymphatic endothelial-like cells.

Human adipose-derived stem cells (hADSCs) may provide a suitable number of progenitors for the treatment of lymphatic edema; however, to date the protocols for inducing hADSCs into this tissue type have not been standardized. We wished to investigate the induction of hADSCs into lymphatic endothelial-like cells using vascular endothelial growth factor-C156S (VEGF-C156S) and other growth factors in vitro. hADSCs from healthy adult adipose tissue were purified using enzyme digestion.

Zoledronic acid exerts antitumor effects in NB4 acute promyelocytic leukemia cells by inducing apoptosis and S phase arrest.

The aim of this study was to investigate the antitumor effect of zoledronic acid (ZOL) in the NB4 human acute promyelocytic leukemia (APL) cell line and explore the potential mechanism of action of this compound. NB4 cells were exposed to various concentrations (0-200μM) of ZOL. Cell viability was measured by MTS assay.

Prognostic value of miR-96 in patients with acute myeloid leukemia.

Objective: Aberrant expression of miRNA (miR)-96 is associated with tumorigenesis and tumor progression in several solid cancers. However, little is known about the expression and prognostic value of miR-96 in acute myeloid leukemia (AML). Therefore, the aim of this study was to investigate the correlation of miR-96 expression with clinicopathological features and prognosis of AML.

[Effects of human umbilical cord mesenchymal stem cells in the treatment of paraquat-induced lung injury].

Objective: To evaluate the clinical effect and safety of human umbilical cord mesenchymal stem cells (HUCMSCs) in the treatment of lung injury caused by acute paraquat poisoning.

Methods: Thirteen patients with lung injury caused by acute paraquat poisoning, who were admitted to Guangzhou No. 12 People's Hospital from December 2008 to December 2012, were divided into HUCMSC group (n = 5) and control group (n = 8).

Analyzing gene expression profile in K562 cells exposed to sodium valproate using microarray combined with the connectivity map database.

To explore the mechanism underlying antileukaemia effect of sodium valproate, the growth and survival of the K562 cell line were investigated. Global profiles of gene expression in K562 cells exposed to sodium valproate were assessed and validated. The differentially expressed genes identified were further used to query the connectivity map database to retrieve a ranked list of compounds that act on the same intracellular targets as sodium valproate.

Using an exon microarray to identify a global profile of gene expression and alternative splicing in K562 cells exposed to sodium valproate.

To investigate the effect of valproate treatment on the K562 cell line, a model for chronic myelogenous leukaemia, the growth and survival of the K562 cell line were investigated using the Annexin-V/PI dual staining method, and global profiles of gene expression and alternative splicing in K562 cells were assessed using exon microarrays. A significant increase in cell apoptosis was observed in valproate-exposed K562 cells using flow cytometry. A total of 628 transcripts were identified as being significantly differentially expressed.

Transplantation of adipose-derived stem cells overexpressing hHGF into cardiac tissue.

The delivery of adipose-derived stem cells (ADSCs) for promoting tissue repair has become a potential new therapy, while hepatocyte growth factor (HGF) is an important growth factor with angiogenic, antifibrotic, and anti-inflammatory benefits. Therefore, transplantation of ADSCs into acute myocardial infarction (AMI) may improve cardiac function through angiogenesis and anti-fibrosis, and that hHGF may enhance these effects. ADSCs were isolated from human subcutaneous adipose tissue.

[Relationship of PTEN, Mdm2 and p53 expression in astrocytoma].

Objective: To study the incidence of PTEN, Mdm2 and p53 expression in different histopathological grades of astrocytoma and the signal transduction mechanism through which PTEN affects Mdm2 and p53 expression.

Methods: Surgical specimens from 68 brain astrocytoma patients were analyzed to detect PTEN, Mdm2 and p53 expression by immunohistochemical method.

Results: The incidence of PTEN, Mdm2 and p53 expression was 54.

15d-PGJ2 inhibits cell growth and induces apoptosis of MCG-803 human gastric cancer cell line.

Aim: To investigate the influence of peroxisome proliferator-activated receptor gamma (PPARgamma) ligand, 15-deoxy-12, 14-prostaglandin J2 (15dPGJ2) on the proliferation and apoptosis of MCG-803 human gastric cancer cell lines.

Methods: Cell proliferation was measured by 3H-TdR assay. Apoptosis was determined by ELISA and TUNEL staining.

[Relationship between tumor necrosis factor genetic polymorphisms and acute lymphocytic leukemia].

Background & Objective: Acute lymphocytic leukemia(ALL), which is sensitive to tumor necrosis factor (TNF) is one of hematological malignances derived from lymphoid tissue. Genetic polymorphisms in the tumor necrosis factor (TNF) locus can affect transcription and expression of TNF genes. This study was designed to investigate the relationship between -308 bp polymorphism in tumor necrosis factor-alpha(TNFalpha) gene and +252 bp in lymphotoxin-alpha(LTalpha) gene and the pathogenesis, clinical course, and outcome of ALL.

[Relationship between cyclins and prognosis of acute leukemia].

Background & Objective: Cell proliferation and differentiation are directed by cell cycle mechanism. When tumor cells proliferate abnormally, cyclins, which are positive agents of cell cycle, may be expressed abnormally at the same time. Now many references proved that cyclins are highly expressed in solid tumors.

[Review of relationship between tumor necrosis factor genetic polymorphism and hematological malignancies].

Patients with malignant tumor including hematological malignancies have high plasma levels of tumor necrosis factor (TNF) and excessive production of TNF is associated with polymorphic variation of TNF locus. TNF polymorphism affects TNF expression by affecting transcriptional regulation. The aim of this paper was to review the correlation between TNF polymorphism and hematological malignancies such as lymphoma, chronic lymphocytic leukemia, hairy cell leukemia, acute lymphocytic leukemia and multiple myeloma and to make preparation for further research of their relationship.
