BACKGROUND: Studies have shown that adipose derived mesenchymal stem cells are involved in the skin repair after scald, but the hydrogel made of the excreta by adipose derived mesenchymal stem cells is rarely reported in the treatment of skin scald. OBJECTIVE: To analyze the therapeutic effect of human adipose derived mesenchymal stem cell conditioned medium hydrogel in a mouse model of skin scald. METHODS: Adipose derived mesenchymal stem cells were obtained from adipose tissues by enzyme digestion combined with adherent culture method. Morphological and flow cytometry were used to identify phenotype and induce differentiation. Secondly, the stable proliferative phase cells were harvested to obtain the conditioned medium, and chitosan, mannitol, beta-glycerol phosphate sodium and hyaluronic acid were added to prepare the thermosensitive hydrogel. Then the 95 ℃ aluminum block was used to rapidly establish a model of degree III skin scald on the left (experimental group) and right (control group) sides of the back of 24 C57BL/6 mice. In the experimental group, adipose derived stem cell conditioned medium hydrogel was applied twice a day on the right side of the mouse back, and in the control group, fresh medium hydrogel was applied twice a day on the left side of the mouse back. The treatment period lasted for 7 days. Healing time and healing process were observed to calculate the healing rate. Histopathological changes were observed by hematoxylin-eosin staining at paraffin sections at 4, 14, 28 days after skin scald. RESULTS AND CONCLUSION: (1) The human adipose derived mesenchymal stem cells had fibroblast-like morphology and proliferated vigorously, and the average doubling time was 55 hours. These cells could be induced to differentiate into osteoblasts, chondrocytes and adipocytes. High expression of CD29, CD44, CD90 and CD105 were observed on these cells with low expression of CD31 and CD34, which met the standard of mesenchymal stem cells. (2) Thethermosensitive hydrogel prepared by the conditioned medium was cool and transparent viscous liquid at 4-20 ℃, and was changed into semi-solid gel at( 37 ℃ after 15 minutes. (3) The normal structure) subcutaneous fat and muscle tissue (of 95 ℃ aluminum block scalded mice wer) standards of degree III burns. The wound area was roughly 3 cm2. (4) In the repair process, shorter wound healing time, less scar and better dermis structure were observed in the experimental group compared with the control group. (5) Inflammatory infiltration, thickness of granulation tissue, epidermal thickness, fibroblasts and vascular density were significantly improved in the experimental group as compared with the control group (P < 0.05). To conclude, human adipose derived mesenchymal stem cells conditioned medium hydrogel can promote the wound healing and promote the quality of regenerated skin after skin scald.

BACKGROUND: This study aimed to explore the effects of TNF-α on the expression of IP3R1 mRNA and protein in human mesangial cells (HMCs), and to elucidate the mechanism of TNF-α relating to IP3R1 expression in the occurrence of hepatorenal syndrome (HRS). METHODS: HMCs were stimulated by tumor (TNF-α) with 100 ng/mL for different hours (2, 4, 8, and 24 hours). The expression changes of IP3R1 mRNA and protein were detected by quantitative real-time polymerase chain reaction and immunoblotting. Several inhibitors including D609, U73122, PP1, safingol, rottlerin and non-radioactive protein kinase C (PKC) were used to examine the mechanism of signal transduction of TNF-α-regulated IP3R1 in HMCs. RESULTS: The levels of IP3R1 mRNA at 2 hours after TNF-α exposure were significantly enhanced and peaked at 8 hours in HMCs (P<0.01), then descended at 24 hours (P<0.01). The levels of IP3R1 protein at 4 hours after TNF-α exposure were obviously increased and peaked at 24 hours after TNF-α exposure (P<0.01). Compared to the control group, safingol (PKCα inhibitor) and D609 (phosphatidylcholine-specific phospholipase C inhibitor) significantly blocked the TNF-α-induced expression of IP3R1 mRNA (3.30±0.81 vs. 1.95±0.13,P<0.05; 2.10±0.49,P<0.01) and IP3R1 protein (3.09±0.13 vs. 1.86+0.39,P<0.01; 1.98±0.02,P<0.01). TNF-α promoted PKCα activation with maximal PKCα phosphorylation that occurred 8 hours after stimulation measured by non-radioactive PKC assay, and the effect was markedly attenuated by pretreatment with D609 or safingol. CONCLUSION: TNF-α increased the expression of IP3R1 and this was mediated, at least in part, through the PC-PLC/PKCα signaling pathways in HMCs.

OBJECTIVETo observe the effects of different therapeutic methods and the recipes of Chinese medicine (CM) on the activation of c-Jun N-terminal kinase (JNK) in Kupffer cells of rats with fatty liver disease and to explore the mechanisms of these therapeutic methods.
METHODSBy using a random number table, 98 rats were randomly divided into 7 groups: control group, model group, and 5 treatment groups, including soothing Liver (Gan) recipe group, invigorating Spleen (Pi) recipe group, dispelling dampness recipe group, promoting blood recipe group, and complex recipe group. Rats in the control group were fed with normal food and distilled water by gastric perfusion, while rats in the model group were fed with high-fat food and distilled spirits by gastric perfusion. Rats in the 5 treatment groups were fed with high-fat food and corresponding recipes by gastric perfusion. Twelve weeks later, all rats were sacrificed and liver tissues were stained for pathohistological observation. Kupffer cells were isolated from livers of rats to evaluate JNK and phospho-JNK expressions by Western blotting.
RESULTSThe grade of hepatic steatosis was higher in the model group than the control group (P<0.05). Compared with the model group, the grade of fatty degeneration in soothing Liver recipe group and invigorating Spleen recipe group were significantly ameliorated (P<0.05). Expressions of JNK and phospho-JNK in Kupffer cells were significantly higher in the model group than those in the control group (P<0.05, P<0.01). Compared with the model group, expressions of JNK in all treatment groups decreased, especially in invigorating Spleen recipe group and promoting blood recipe group (P<0.05). Compared with the model group, expressions of phospho-JNK in all treatment groups declined significantly (P<0.01), especially in soothing Live recipe group and invigorating Spleen recipe group.
CONCLUSIONSThe high expressions of JNK and phospho-JNK in Kupffer cells might play an important role in the pathogenesis of fatty liver disease in rats. The recipes of CM, especially invigorating Spleen recipe and soothing Liver recipe, might protect liver against injury by reducing the total JNK protein content and inhibiting the activation of JNK protein in Kupffer cells of fatty liver model rats, which showed beneficial effects on fatty liver disease.

OBJECTIVETo study the effect of growth factor-primed donor hematopoietic stem cells infusion (GPBSCI) as an early adoptive immunotherapy.
METHODSTwelve patients with high-risk leukemia received prophylactic GPBSCI after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Out of the 12 patients, two were Ph(+) ALL in CR(1), one ALL in CR(2), one refractory ALL, three AML (one in relapse, one refractory disease, one in CR(3)), four CML in advanced stage and one myelodysplastic syndrome-refractory anemia with excess blast (MDS-RAEB).
RESULTSSixteen infusions were performed in the 12 patients, including 5 infusions were performed within +90 days post-SCT. The median mononuclear cells (MNC) and CD3(+) cells infused for GPBSCI before +90 d were 1.00 (0.95 - 1.24) x 10(8)/kg and 0.53 (0.39 - 0.63) x 10(8)/kg, and after +90 d were 2.27 (1.00 - 4.30) x 10(8)/kg and 1.15 (0.55 - 2.10) x 10(8)/kg, respectively. Four patients developed grade I - II acute GVHD, and one grade III acute GVHD. Seven patients developed chronic GVHD, of which four cases were extensive. Two patients had no transfusion related GVHD. No transfusion related pancytopenia was observed. Ten patients survived disease-freely at 563 (415 - 728) days of follow-up. Two patients died of leukemia relapse after GPBSCI.
CONCLUSIONAllo-HSCT with prophylactic GPBSCI could maximize graft-versus-leukemia effect with few fatal complications and might be a potentially curative strategy for hematological malignancy patients with high risk of relapse.
