BACKGROUND:Mesenchymal stem celltransplantation promoted skin repair in trauma via various regulatory mechanisms and inhibited scar formation. At present, many scholars believed that bioactive factors secreted by mesenchymal stem cells played an important role.
OBJECTIVE:To investigate the effects of bone marrow mesenchymal stem cellconditioned medium on the proliferation and col agen synthesis of hypertrophic scar fibroblasts.
METHODS:Human bone marrow mesenchymal stem cells and hypertrophic scar fibroblasts were isolated and cultured, and bone marrow mesenchymal stem cellconditioned medium was prepared. Hypertrophic scar fibroblasts were cultured in vitro with 12, 24, and 48 hour-col ected conditioned medium for 24 hours, which was compared with blank control group. The proliferation of cells was determined by CCK-8. Type I and type III col agen expression in hypertrophic scar fibroblasts was detected using real-time PCR.
RESULTS AND CONCLUSION:Compared with the blank control group, 24 and 48 hour-col ected conditioned medium significantly inhibited the proliferation of hypertrophic scar fibroblasts (P<0.01), and also suppressed col agen synthesis of hypertrophic scar fibroblasts (P<0.01). Results suggested that bone marrow mesenchymal stem cellconditioned medium inhibited the proliferation and col agen synthesis of hypertrophic scar fibroblasts by secreting anti-fibrotic bioactive factors, which may provide new theoretical supports for celltherapy to reduce cutaneous scarring.

Objective To detect the change of serum cystatine C ( cys C ) level in Parkinson ’ s disease ( PD ) patients with obstructive sleep apnea-hypopnea syndrome ( OSAHS ) and explore its influencing factors .Methods Fifty-six PD patients with polysomnography examination from July 2011 to December 2013 in the Department of Neurology , the Second Affiliated Hospital of Soochow University were collected.Eighteen healthy controls who took the polysomnography examination during the same period were included.According to the apnea-hypopnea index ( AHI) , PD patients were further divided into two groups:PD with OSAHS group ( n=26 ) , and PD group ( n=30 ).The general conditions , movement function , biochemistry parameters , and sleep parameters were assessed.Statistical analysis was performed using SPSS ver 17.0 software.Results The mean serum levels of cys C in PD with OSAHS group , PD group and control group were (1.05 ±0.17) mg/L, (0.96 ±0.12) mg/L and (0.84 ±0.20) mg/L, respectively.Statistical analysis showed that there was significant difference in the three groups (F=9.184,P<0.05), and the mean serum level of cys C in PD with OSAHS group was the highest.In PD with OSAHS group , Spearman correlation analysis showed a positive and significant correlation between cys C levels and creatinine levels (r=0.459,P =0.018), urea levels (r =0.405,P =0.040), AHI (r =0.482,P =0.013), the oxygen desaturation index (r=0.408,P=0.038), the arousal index (r=0.392,P=0.047) as well as Hoehn and Yahr (H-Y) stage (r=0.467,P=0.016).Correlation was not observed between cys C levels and other clinical parameters (P>0.05).Multivariate analysis showed that creatinine levels (B=0.007,P=0.005), AHI (B=0.004,P=0.013) , H-Y stage (B=0.102,P=0.026) may be influencing factors of cys C levels in PD patients (P<0.05).Conclusions Cys C level is elevated in PD patients, especially in PD patients with OSAHS.The degree of hypoxia and severity of PD is related to the level of cys C in PD patients with OSAHS .

BACKGROUND:The proteome is a highlight technology in medical research fields lately, and has been reported to be applied in basic research fields related to liver transplantation. However, it has not been heard that the proteome has been used in research related to reduced-size liver transplantation. OBJECTIVE: To study expression of hepatic differential proteins related to signal transduction using proteomics after reduced-size liver transplantation in rats. METHODS:On the basis of successful establishment of rat models of reduced-size liver transplantation, transplanted liver tissues were obtained at 1, 3 and 7 days after transplantation. Postoperative liver tissue and normal donor, receptor liver tissues were subjected to solid pH gradient two-dimensional gel electrophoresis. Two-dimensional gel electrophoresis patterns were set up. Differentialy expressed protein spots were identified using tandem mass spectrometry analysis and database. RESULTS AND CONCLUSION:Seventy-two differential protein stains were found taking 10 times measure. Finaly, 32 proteins with clear functions were identified. Of them, four proteins participated in signal transduction, and they distributed at 3 and 7 days after liver transplantation, accounting for 6%. Results verified that on the basis of successful and stable establishment of rat models of reduced-size liver transplantation, proteomics technology was utilized to study differential proteins involving in signal transduction after reduced-size liver transplantation, and this study provides data for further deep investigation of regulating MicroRNA of these proteins.

BACKGROUND:At present, the proteome is a mature technology that has been applied in basic research fields related to liver transplantation. But, it has been not reported in research related to reduced-size liver transplantation.
OBJECTIVE:To explore the expression of differential proteins related to hepatic energy metabolism fol owing reduce-size liver transplantation in rats by using by proteomic technology.
METHODS:The improved model of reduced-size liver transplantation was used in this experiment. The donor was health female Lewis rats and the recipient was male Wistar rats for liver transplantation. The difference between the donor and the recipient was about 20 g. The weight of donor liver/the weight of recipient donor was approximately equal to 50%. The donor liver tissue was harvested and trimmed to the required size. The portal vein and infrahepatic vena cava were cannulated, and the biliary tract was implanted into the donor bile duct for transplantation. Then the donor was transplanted into the recipient after the removal of original liver tissue. Hepatic specimens were harvested by 1, 3 and 7 days after reduced-size liver transplantation. Then, the harvested specimens were compared with the normal donor and recipient liver tissue that were previously harvested and frozen, to generate two-dimensional gel electrophoresis profile using proteome technology. Then tandem mass spectrometry and databases analysis were performed after two-dimensional electrophoresis for identifying differential protein stains.
RESULTS AND CONCLUSION:In this experiment, 72 differential protein stains with over lo-fold changes were selected. After identification, 32 proteins showed clear functions, and among them three differential proteins (ATP synthase beta subunit, electron-transferring flavoprotein beta peptide and proton-transferring ATP synthase) were involved in the process of cel energy metabolism. The proteins were distributed on 1 and 7 days after reduce-size liver transplantation, accounting for 6%.

Based on the transcriptome data, we cloned the open reading frame of IiHCT gene from Isatis indigotica, and then performed bioinformatic analysis of the sequence. Further, we detected expression pattern in specific organs and hairy roots treated methyl jasmonate( MeJA) by RT-PCR. The IiHCT gene contains a 1 290 bp open reading frame( ORF) encoding a polypeptide of 430 amino acids. The predicted isoelectric point( pI) was 5.7, a calculated molecular weight was about 47.68 kDa. IiHCT was mainly expressed in stem and undetectable in young root, leaf and flower bud. After the treatment of MeJA, the relative expression level of IiHCT increased rapidly. The expression level of IiHCT was the highest at 4 h and maintained two fold to control during 24 h. In this study, cloning of IiHCT laid the foundation for illustrating the biosynthesis mechanism of phenylpropanoids in I. indigotica.
