OBJECTIVEBy using the metabonomics method, to study the plasma metabonomics of the stable phase chronic obstructive pulmonary disease (COPD) patients of Fei-qi deficiency syndrome (FQDS), and of Chinese materia medica (CMM) intervention, thus exploring possibly existent biomarkers.

METHODSForty stable phase COPD patients of FQDS were recruited as Group A. Liuwei Buqi Capsule (LWBQC) was given to them as intervention. A healthy control group (Group B, 37 cases) was set up. The pulmonary function test was performed on patients in Group B and Group A before and after intervention. The plasma metabolites were detected using high performance liquid chromatography-mass spectrometry (HPLC-MS/MS). Statistical data were analyzed using principal component analysis (PCA) and partial least squares (PLS). The original spectrum and data of plasma metabonomics were compared between the two groups. The whole spectrum amino acid metabonomics tests were performed in the two groups.

RESULTSCompared with Group B, the pulmonary function significantly decreased before intervention in Group A (P < 0.05). The pulmonary function was more mildly improved after 30 days' treatment than before treatment, but still lower than it in Group B (P < 0.05). The metabolic spectrum before treatment in Group A was significantly different from Group B, but showing regressive trend to Group B after treatment. Fifteen possible disease markers were found in COPD patients of FQDS. Results of the whole spectrum of amino acid metabolomics showed different features.

CONCLUSIONSThe changes of metabolic spectrum and amino acids could be found in the stable phase COPD patients of FQDS using plasma metabonomics, and potential markers could be detected. The intervention of the stable phase COPD patients of FQDS by Chinese medicine could brought positive changes in the metabolic profiling and amino acid metabolism.

OBJECTIVETo establish an experimental animal model of Alzheimer's disease (AD) with clinical and pathological specificity conformed to AD in human, and to observe the effect of Zhinao Capsule (ZNC) on learning, memory and patho-morphological parameters in the model.

METHODSThe experimental AD model of rats was improved and established by combined injection of beta-amyloid protein (beta-AP) to lateral ventricle and transforming growth factor beta 1 (TGF beta 1) to brain. The learning and memory function of the model rats were tested by step-through test and water-maze test, and the number and cross area of beta-AP deposited macula in cerebral cortex and CA1 region of hippocampus were estimated quantitatively using immunohistochemical method and image pattern analysis.

RESULTSThe improved AD animal model showed both the specificity of behavior (learning and memory impairments) and the typical pathological specificity (beta-AP deposited macula). ZNC could effectively improve the impairment of learning and memory and reduce the number and cross area of beta-AP deposited macula in cerebral cortex and hippocampus CA1 region in the AD model rats.

CONCLUSIONThe AD rat model induced by the combined injection of beta-AP and TGF beta 1 is a good animal model simulated to the clinical reality, which could be used to screen and evaluate the anti-dementia agents. ZNC could display anti-dementia effect of the AD model rats.

OBJECTIVETo screen the molecular markers for refractory anemia with excess blasts in transformation (RAEB) in myelodysplastic syndromes (MDS) by serum proteome profiling.

METHODSThe serum protein were isolated from patients with RAEB, acute myeloid leukemia or normal subjects by 2-dimensional electrophoresis (2-DE), and the electrophoresis gels were obtained to identify the differentially reacting protein spots. The replica gels of the differentially reacting proteins were analyzed to locate the matching protein spots, which were identified by peptide mass fingerprint based on matrix-assisted laser desorption/ionization time of-flight mass spectrometry (MALDI-TOF-MS) and database searching.

RESULTSSeven differentially expressed proteins in RAEB were found by 2-DE. Of the 7 proteins, 4 were identified by MALDI-TOF-MS to have significantly differential expression in RAEB, including dipeptidyl peptidase (DPP/CD26), polymerase (DNA directed) kappa, PRO2044 and an albumin-like protein.

CONCLUSION2-DE-based serum proteome profiling helps identify serum proteomic biomarkers related to MDS. DDP/CD26 has increased expression in the serum in RAEB subtype MDS, suggesting its possible role in advanced MDS.

TGFβ/smad pathway is recognized as an important signal pathway to promote the pathogenesis of atherosclerosis (AS). Peroxisome proliferator-activated receptor γ (PPARγ) activation is considered to be important in modulating AS. Herein, we investigated the regulation of PPARγ on c-Ski, the repressor of TGFβ/smad pathway, in rat AS model and cultured vascular smooth muscle cells (VSMCs). c-Ski mRNA and protein expression were detected by real-time PCR and Western blot, respectively, in vivo and in vitro with treatment of PPARγ agonist rosiglitazone and antagonist GW9662. The proliferation and collagen secretion of VSMCs after c-Ski transfection were investigated. The underlying mechanism was further investigated by online program NUBIScan and luciferase reporter gene analysis. Results showed that both mRNA and protein expressions of c-Ski in the AS lesions was down-regulated in vivo, while in cultured VSMCs, c-Ski transfection significantly suppressed the proliferation and collagen secretion of rat VSMCs. Rosiglitazone significantly up-regulated mRNA and protein levels of c-Ski in VSMCs, which could be blocked by GW9662. Online NUBIScan analysis suggested possible PPARγ binding sites in the promoter region of c-Ski. In addition, luciferase activity of c-Ski reporter gene was also increased obviously in the presence of rosiglitazone. These results indicate that c-Ski is one of the newly found target genes of PPARγ and thus involved in the anti-AS effect of PPARγ.

OBJECTIVETo analyze the promoter methylation levels of p15, CDH1, DAPK and HICI genes of patients with myelodysplastic syndrome (MDS) and explore the relationship between the level of methylation and clinical features.

METHODSDNA methylation levels of p15, CDH1, DAPK and HICI in peripheral blood (PB) or bone marrow (BM) samples from 52 MDS patients were detected by real-time quantitative PCR. The correlation of the methylation level with clinical features and hematological findings was analyzed. 38 de novo AML patients and 46 normal individuals served as controls.

RESULTSThe methylation levels of p15, CDH1, DAPK and HICI were 16.23 ± 21.69, 6.59 ± 9.39, 0.14 ± 0.11 and 7.81 ± 9.70 in BM, and 14.96 ± 20.16, 6.00 ± 9.26, 0.12 ± 0.14 and 6.74 ± 9.72 in PB, respectively from 18 MDS patients, and the difference between BM and PB was not statistically significant (P > 0.05). The methylation levels of p15 (14.70 ± 18.17) and CDH1 (6.61 ± 8.79) genes in high risk (RAEBI/II) MDS were significantly higher than in low risk (RCMD/RARS/5q-, p15: 1.99 ± 1.59, CDH1: 1.23 ± 1.14 and RCMD, p15: 3.02 ± 3.42, CDH1:1.53 ± 2.06) MDS or control (p15: 1.69 ± 1.82, CDH1: 1.01 ± 1.12) (P < 0.05). The methylation levels of DAPK gene had no difference among subtypes of MDS, and that of HIC1 gene only differed between RAEB I/II (9.16 ± 11.95) and control (2.49 ± 2.26) (P = 0.042). The difference of methylation levels of p15, CDH1, DAPK and HICI in BM was statistically significant among subtypes of MDS (P = 0.001, 0.003, 0.039, 0.023, respectively). And so did of p15 and DAPK in PB (P = 0.013, 0.006, respectively). The methylation level of p15 and CDH1 was significantly correlated with IPSS classification and blasts percentage in BM.

CONCLUSIONSp15 and CDH1 genes are special hypermethylation genes in MDS. Methylation level of HIC1 gene showed an upward tendency from low risk to high risk MDS.
