To investigate whether human umbilical cord plasma (HUP) can be used to culture human cord blood mesenchymal stem cells (HUCMSCs), we collected 20 surplus HUP. After being treated with salting out and diasysis, the HUP were used to culture HUCMSCs as 10% volume, and compared with fetal bovine serum (FBS). Morphological characteristics, growth curve and reproductive activity of HUCMSCs cells were observed. The concentration of bFGF and noggin secreted by HUCMSCs cultured with HUP and FBS medium were detected by ELISA. It was found that compared to FBS, the morphology, reproductive activity and characteristic of HUCMSCs cell cultured with HUP were not distinctively different from FBS. The concentration of bFGF in HUP group was significantly higher than that of FBS group, and the concentration of noggin was also different in the two groups. So we concluded that HUP could be used to culture HUCMSCs for a long-time, and the HUP mediumcoild could be more suitable for the culture of human embryonic stem cell (hESC).

Purpose Early diagnosis of Alzheimer's disease is lack of objective imaging marker.This study evaluates characteristics of cerebral blood flow (CBF) and gray matter atrophy in patients with mild Alzheimer's disease (AD) by using 3D arterial spin labeling (3D ASL) and thin slice 3D T1 weighted images of voxel-based method (VBM).Materials and Methods Sixteen mild AD patients (mild AD group) and sixteen normal control subjects (control group) were recruited.3D ASL and T1WI SPGR sequences were performed.By using voxel-based method,the whole brain CBF and T1WI images were analyzed.CBF and volume of gray matter were compared between two groups,and correlation analysis was done.Results Compared with control group,CBF hypoperfusion was detected in bilateral precuneus,cunei,middle temporal cortex,superior temporalcortex,left parahippocampal gyrus,left superior temporal pole and right superioroccipital gyrus in mild AD group (t=3.84,Pcorrected＜0.05).Compared with control group,gray matter atrophy was found in bilateral hippocampi,amygdalae,superior temporal pole,left parahippocampal gyrus,left inferior temporal cortex in mild AD group (t=4.12,Pcorrected＜0.05).There was a correlation in left parahippocampal gyrus and left upper pole of the temporal between changes of CBF and volume of gray matter in mild AD patients (r=0.50,P＜0.05).Conclusion Voxel-based VBM and ASL can evaluate AD patients' cerebral atrophy and CBF change in early stage,and there is a correlation between changes of CBF and gray matter atrophy in some overlap areas.

Objective: To evaluate the feasibility and effect of transcatheter closure of ventricular septal defects(VSD) using the VSD occluder.Methods: From December 2003 to March 2005,13 VSD patients,8 males and 5 females,ranging in age from 4 to 35(15.2?10.7)years,underwent catheter closure using the VSD occluder.Tthe mean diameter of the VSD obtained by transthoracic echocardiography was 4-12(5.4?1.2) mm.Transcatheter closure was performed under transthoracic echocardiographic guidance after left ventriculography.All patients were followed up 1,3 and 6 months after the procedures. Results: The devices were successfully placed in 12 of the patients and complete closure achieved in 11.Trace residual shunt was observed in 1 patient but disappeared within 10 minutes.No severe complications were noted except 1 case of complete right bundle branch block revealed by electrocardiography. Conclusion: Transcatheter closure of VSD by the VSD occluder is a safe and effective procedure,with good immediate results.Further clinical trials are under way to assess its long-term effect.

BACKGROUND: There is a growing recognition that the adipose tissue is an endocrine organ that secretes signaling molecules such as adiponectin and resistin. The peroxisome proliferator activated receptor γ (PPARγ) is expressed in high levels in the adipose tissue. Thiazolidinediones are selective PPARγ agonists with insulin-sensitizing properties. It has been postulated that thiazolidinediones such as rosiglitazone exert their pharmacodynamic effects in part through modulation of resistin (implicated in insulin resistance) and adiponectin (an insulin-sensitizing molecule) expression subsequent to activation of PPARγ. There are conflicting data, however, on the biological direction in which resistin expression is modulated by PPARγ agonists and whether an increase in adiponectin expression can occur in the face of an upregulation of resistin. METHODS: Using the murine 3T3-L1 adipocytes as a model, we evaluated the changes in resistin and adiponectin gene expression after vehicle, rosiglitazone (10 μmol/L, a PPARγ agonist), GW9662 (5 μmol/L, a selective PPARγ antagonist) or GW662 and rosiglitazone co-treatment.RESULTS: In comparison to vehicle treatment, rosiglitazone increased the average adiponectin and resistin mRNA expression by 1.66- and 1.55-fold, respectively (P＜0.05). Importantly, GW9662 also upregulated adiponectin expression (by 1.57-fold, P＜0.05) but did not influence resistin expression (P＞0.05). Co-treatment with rosiglitazone and GW9662 maintained the adiponectin upregulation (1.87-fold increase from vehicle, P＜0.05) while attenuating resistin upregulation (1.31-fold increase from vehicle, P＜0.05) induced by rosiglitazone alone (1.55-fold increase from vehicle, P＜0.05). CONCLUSION: This study presents new evidence that adiponectin transcript is upregulated with both a PPARγ agonist (rosiglitazone) and antagonist (GW9662), while GW9662 co-treatment does not block rosiglitazone-induced adiponectin upregulation. These data collectively suggest that biological mechanisms independent from PPARγ may underlie thiazolidinedione pharmacodynamics on adiponectin expression. Moreover, increased adiponectin expression by GW9662, in the absence of an upregulation of resistin expression, lends further support on the emerging clinical potential of PPARγ antagonists in treatment of insulin resistance. Decreased resistin expression may not be crucial for the insulin-sensitizing effect of rosiglitazone. These findings may serve as a foundation for future dose-ranging and time-course studies of thiazolidinedione pharmacodynamics on adipocytokine expression in human adipocytes.
