OBJECTIVETo study the molecular mechanisms of Curcuma Wenyujin extract-mediated inhibitory effects on human esophageal carcinoma cells.

METHODSThe Curcuma Wenyujin extract was obtained by supercritical carbon dioxide extraction. TE-1 cells were divided into 4 groups after adherence. 100 microL RMPI-1640 culture medium containing 0.1% DMSO was added in Group 1 as the control group. 100 microL 25, 50, and 100 mg/L Curcuma Wenyujin extract complete culture medium was respectively added in the rest 3 groups as the low, middle, and high dose Curcuma Wenyujin extract groups. The effects of different doses of Curcuma Wenyujin extract (25, 50, and 100 mg/L) on the proliferation of human esophageal carcinoma cell line TE-1 in vitro were analyzed by MTT assay. The gene expression profile was identified by cDNA microarrays in esophageal carcinoma TE-1 cells exposed to Curcuma Wenyujin extract for 48 h. The differential expression genes were further analyzed by Gene Ontology function analysis.

RESULTSCompared with the control group, MTT results showed that Curcuma Wenyujin extract significantly inhibited the proliferation of TE-1 cells in a dose-dependent manner (P<0.05). The expression level of 88 genes changed with significance, including 66 up-regulation genes and 22 down-regulation genes. Gene Ontology analysis indicated the genes coding for proteins was involved in signal transduction (6), cell cycle (8), apoptosis (14), and cell differentiation (10).

CONCLUSIONSThe Curcuma Wenyujin extract could inhibit the growth of human esophageal carcinoma cell line TE-1 in vitro. The molecular mechanisms might be associated with regulating genes expressions at multi-levels.

OBJECTIVETo construct recombinant plasmid pEGFP-BMP7 and determine its expression in rat bone marrow mesenchymal stem cells (MSCs) in vitro.

METHODScDNA of target gene was obtained from neonatal rat kidney by RT-PCR. After sequencing the target gene, the cDNA was subcloned into a eukaryote plasmid pEGFP-N1 by directed cloning and then digested with two restrictive endonucleases to verify the correctiveness of the recombinant plasmid pEGFP-BMP7. Rat bone marrow MSCs were transiently transfected with the pEGFP-BMP7 and transfection efficiency of the Green Fluorescent Protein (GFP) was determined. RT-PCR and immunocytochemical analysis were also performed to detect the expression of BMP7 in rat MSCs.

RESULTS1 311 bp cDNA fragment was obtained by RT-PCR and sequence analysis showed it matched perfectly with that of rat BMP7 gene except a single nucleotide change at 756 bp from T to A. Digestion of the recombinant plasmid showed two 1.3 kb and 4.7 kb fragments and their size were same as those of BMP7 and pEGFP. This indicated that BMP7 cDNA was successfully subcloned into pEGFP. Transient transfection showed an efficiency of 33% at day 2 in rat MSCs. After transfection, transcription of BMP7 was detected in MSCs and expression of BMP7 protein was also verified.

CONCLUSIONRecombinant eukaryote plasmid pEGFP-BMP7 was successfully constructed and expressed in rat bone marrow MSCs. This procedure may provide a unique method for stimulation of callus formation in distraction osteogenesis and reconstruction of craniofacial bone defects.

OBJECTIVETo observe the effects of mesenchymal stem cells (MSCs)on cranial suture under mechanical strain in growing goats.

METHODS10 growing goats were used in this study. A customized distractor was used for distraction of the coronal suture at a rate of 0.4 mm/day for 8 days. The experimental group(5 goats) was injected with autologous MSCs into the distracted region, whereas the control group (5 goats) with injection of physiological saline. All animals were killed at 4 weeks after the end of distraction. Scanning electron microscopy and histological analysis were taken to observe the samples.

RESULTS4 weeks after the end of distraction, the cranial sutures in all animals were separated successfully. The new bone formation at the edge of suture in the experimental group was superior to that in the control group.

CONCLUSIONAutologous MSCs transplantation may promote the cranial suture distraction osteogenesis in the growing goats.

OBJECTIVETo review the surgical treatment of supracardiac type of total anomalous pulmonary venous connection (TAPVC).

METHODSTwenty-four patients with supracardiac total anomalous pulmonary venous connection underwent surgical correction from July 1995 to June 2004. There were 11 males, 13 females. The patients aged from 40 days to 35 years (mean 4.5 years). Twenty-three patients were under 6 years old. The weight was from 3.8 to 54.0 kg (mean 17.5 kg). Ten patients were through right atrial incision, 8 through double-atrium incision to anastomose the left atria and the common pulmonary veins. Two used large patches separating the portal of the common pulmonary veins and the enlarged atrial septal defects to the left atria. The left atrium and the common pulmonary veins were anastomosed in one case using a large patch separating the portal of the common pulmonary vein and the enlarged atrial septal defect to the left atrium. Three anastomosed the top of the left atria and the common pulmonary veins.

RESULTSOne patient died postoperatively of low cardiac output syndrome. One with cardiac tamponade after operation was cured by reoperation. Six with arrhythia were all cured. One with acute pulmonary edema was cured by reopen of the vertical vein and closed later. The postoperative follow-up period ranged from 3 months to 7 years (mean 2.5 years). One complicated severe supracardiac arrhythia 2 weeks later. One with late pulmonary occlusion was cured by reoperation. There was no long term complication of the others.

CONCLUSIONSThe operative methods of TAPVC depend on the cardiac deformation. Proper surgery timely treatment of the postoperative complications may achieve a satisfactory result. The method of only use patch in the right atrium should select proper repair material. Anastomosing the top of the left atrium and the common pulmonary vein is a good method. It is easy for exposure and operating, meanwhile it has low occurrence of arrhythmias and should be recommended.

AIMUnderstanding the response of mesenchymal stem cells (MSCs) to mechanical strain and their consequent gene expression patterns will broaden our knowledge of the mechanobiology of distraction osteogenesis.

METHODOLOGYIn this study, a single period of cyclic mechanical stretch (0.5 Hz, 2,000 microepsilon) was performed on rat bone marrow MSCs. Cellular proliferation and alkaline phosphatase (ALP) activity was examined. The mRNA expression of six bone-related genes (Ets-1, bFGF, IGF-II, TGF-beta, Cbfa1 and ALP) was detected using real-time quantitative RT-PCR.

RESULTSThe results showed that mechanical strain can promote MSCs proliferation, increase ALP activity, and up-regulate the expression of these genes. A significant increase in Ets-1 expression was detected immediately after mechanical stimulation, but Cbfa1 expression became elevated later. The temporal expression pattern of ALP coincided perfectly with Cbfa1.

CONCLUSIONThe results of this study suggest that mechanical strain may act as a stimulator to induce differentiation of MSCs into osteoblasts, and that these bone-related genes may play different roles in the response of MSCs to mechanical stimulation.
