Stem cells transplantation improved the hepatic function and pathology in acute hapatic injury model of nude mice.

ObjectiveTo examine whether Shenfu injection (SFI) reduces post-resuscitation myocardial dysfunction in a pig model by modulating expression imbalance of transcription factors of regulatory T cell, namely GATA-3 and T-bet.Methods Thirty pigs were randomly divided into sham group (n = 6) and cardiopulmonary resuscitation (CPR) group (n = 24) according to the random number table method, and the pigs in the CPR group were randomly subdivided into normal saline (NS) group, epinephrine (EP) group, and SFI group (n = 8 per group). After 8minutes of untreated ventricular fibrillation (VF) followed by 2 minutes of CPR, animals in three groups respectively received central venous injection of either 20 mL SFI (1.0 mL/kg, SFI group), EP (0.02 mg/kg, EP group) or NS (NS group). Blood samples were obtained before VF and 0.5, 2, 6 hours after restoration of spontaneous circulation (ROSC), and the parameters of hemodynamics and oxygen metabolism were determined. Surviving pigs were sacrificed at 24 hours after ROSC, the pathological changes in myocardium were observed, the levels of interleukin-4 (IL-4), tumor necrosis factor-α (TNF-α) andγ-interferon (IFN-γ) were measured by enzyme linked immunosorbent assay (ELISA), and expressions of protein and mRNA of GATA-3 and T-bet were determined by Western Blot and quantitative real-time polymerase chain reaction (RT-qPCR), respectively.Results Six pigs of three resuscitation groups were successfully resuscitated. The CPR time, number of defibrillation, defibrillation energy, and ROSC time were significantly decreased in the EP and SFI groups compared with those in the NS group. Compared with the sham group, the parameters of left ventricular systolic function and oxygen metabolism were significantly decreased, myofibril organelles were extensively damaged, and progressive and severe deterioration of the myocardium was found, and mitochondrial structure was not recognizable in the NS group; the level of IL-4 in myocardium were markedly decreased, while that of TNF-α, IFN-γand IFN-γ/ IL-4 [reflecting helper T cell 1/2 (Th1/Th2)] were significantly increased. Protein and mRNA expressions of GATA-3 were markedly reduced in the myocardium of pigs in the NS group compared with that of the sham group at 24 hours after ROSC, while T-bet was significantly increased. Compared with the NS group, animals treated with SFI had minimal myocardial intracellular damage, with decreased heart rate (HR, bpm: 90.33±3.79 vs. 106.83±5.36) and increased mean arterial pressure (MAP), cardiac output (CO), oxygen delivery (DO2), and oxygen consumption (VO2) at 6 hours after ROSC [MAP (mmHg, 1 mmHg = 0.133 kPa): 107.67±1.96 vs. 86.83±1.85, CO (L/min): 2.47±0.08 vs. 2.09±0.04, DO2 (mL/min): 364.31±4.21 vs. 272.33±3.29, VO2 (mL/min): 95.00±2.22 vs. 82.50±2.28, allP<0.05]. Compared with the NS groups at 24 hours after ROSC, level of IL-4 was markedly increased in myocardial cells (ng/L: 33.80±3.06 vs. 16.15±1.34,P< 0.05), while the levels of TNF-α, IFN-γ and IFN-γ/IL-4 were lowered significantly [TNF-α (ng/L): 18.16±0.71 vs. 29.64±1.89, IFN-γ (ng/L): 373.75±18.36 vs. 512.86±27.86, IFN-γ/IL-4: 16.15±1.34 vs. 33.80±3.06, allP< 0.05], and myocardial T-bet protein and mRNA expressions were reduced [T-bet protein (gray value): 0.41±0.07 vs. 0.59±0.11, T-bet mRNA (2-ΔΔCt): 4.37±0.21 vs. 7.57±0.55, bothP< 0.05], furthermore, myocardial GATA-3 protein and mRNA expressions were significantly up-regulated in SFI group [GATA-3 protein (gray value): 0.25±0.07 vs. 0.16±0.07, GATA-3 mRNA (2-ΔΔCt): 0.63±0.07 vs. 0.34±0.05, bothP< 0.05]. The parameters in SFI group were significantly improved compared with those of the EP group.ConclusionsMyocardial immune dysfunction is induced by Th1/Th2 imbalance following myocardial injury subsequent to CPR in pigs. SFI can attenuate myocardial injury and regulate myocardial immune disorders, protect post-resuscitation myocardial injury by modulating expression imbalance of transcription factors GATA-3 and T-bet.

Objective To investigate the clinical efficacy of colonoscopic metal stenting and ileus tube catheteriza-tion on left colorectal cancer with acute obstruction. Methods Clinical data of 80 patients meeting the diagnostic criteria for acute obstruction of the left half of colorectal cancer were included in this study. Patients were randomly divided into met-al stent group (n=40) and ileus tube group (n=40). The metal stent group was treated by metal stent and the ileus tube group was treated by ileus tube. Both were carried on by colonoscopy and X-line. After the relief of obstruction ( 7-10 d), patients were underwent colorectal cancer radical resection and anastomosis. The technical operations, improvement of obstruction and the efficacy of surgical treatment were compared between two groups. Results The success rate was 87.5%in metal stent group and the 97.5%in ileus tube group. There was no significant difference in the success rate between two groups (P>0.05). No complications were found in two groups. The operation time and the treatment cost were higher in metal stent group than those in ileus tube group. The relief rates of obstruction were 100%and 95%for metal stent group and ileus tube group, and there was no difference between them. Two cases were operated for emergency because of the failure of obstruc-tion relief. The relief time of obstruction and the difference between C-reactive protein values were much better in metal stent group than those of ileus tube group. After the obstruction relief, patients underwent a radical resection of the tumor and anastomosis, no anastomotic leakage was found in two groups. There were no significant differences in the operation time, in-cision infection and hospitalization time between two groups. Conclusion Anal ileus tube catheterization has a better eco-nomic value in the treatment of acute obstruction, but the efficacy of metal stent is better.

ObjectiveTo isolate and culture human adipose derived mesenchynal stem cells (hADSCs) and study the potential of hADSCs to differentiate into hepatocyte-like cells. MethodsTo ensure the removal of contaminating hematopoietic cells, hADSCs were selected based on plastic adherence. Cell surface antigen was confirmed by flow cytometry; ultramicrostructure was detected by transmission electron microscopy; adipogenic and osteogenic differentiation of hADSCs was analyzed by oil Red O staining and yon Kossa staining. hADSCs were exposed to differentiation medium containing EGF,FGF,OSM, HGF,TSA in vitro. 10% CCl4 (100 μ1/20 g body weight )was injected into immune-deficient BALB/c-nu mice and hADSCs (5 × 105 cells) were simultaneously administrated from the tail vein. Blood samples were collected and concentration of aminotransferase and direct bilirubin were detected. Administration without hADSCs was used as a control. One month later, we sacrificed the mice and liver sections were examined by histochemical immunofluorescence with human ALB specific antibodies. ResultshADSCs exhibited fibroblast-like morphology, and expressed CD73, CD90,CD105, and were lacking of CD34 and CD45. Adipogenic and osteogenic differentiation showed that hADSCs have the capacity of multidifferentiation. The differentiated cells showed hepatocyte-like cell morphologies and hepatocyte-specific markers including albumin (alb) and α-fetoprotein (AFP). The bioactivity assays revealed that these hepatocyte-like cells could uptake low-density lipoprotein (LDL).Histochemical immunofluorescence showed that hADSCs were incorporated into injured livers. Some human alb-positive cells were found in liver sections after implantation of undifferentiated hADSCs. Transaminase activity in the experimental group was lower than in the control group. Conclution hADSCs can differentiated into functional hepatocyte-like cells and can relieve CCl4 induced BALB/c-nu acute liver injury.
