Cell-based therapy and regenerative medicine offer a paradigm shift in regard to various diseases causing tissue or organ damage.Recently,many authors have focused their atte(n)tion on adipose-derived mesenchymal stem cells (ADMSCs) for their capacity to differentiate into many cell lineages.Acute kidney injury (AKI),as a common emergency,has high morbidity rate and relatively limited treatment.This review will summarize the mechanism of ADMSCs in treatment of acute kidney injury,and hope to lay a foundation for future research.

Objective To investigate the postmortem redistrib ution of morphine in rat model of chronic morphine poisoning. Methods Samples including cardiac blood, liver, heart, kidney, lung and brain tissues were collected in the rats with chronic morphine poisoning at 0~96 h after death, respectively. The morphine amount was measured with solid phase ext raction-gas chromatography. Results The study showed an increase in morphine concentrat ion of postmortem cardiac blood. Significant increase in morphine level was also observed 24~96 h after death in liver, heart and brain tissues, while the kid ney morphine levels decreased at 96 h after death. In the liver there was the g reatest increase (25-fold) in morphine levels 96 h after death. All the sample s showed marked alterations in morphine concentration within 96 h after death c ompared with cardiac blood at time of death. The postmortem morphine levels in b rain were closely related to those in the heart blood. Conclusion The postmortem redistribution of morphine exists in rats with chronic morphine poisoning. The brain tissues may better represent morphine levels in heart blood at the time of death.

Recepteur d′origine Nantais(RON),a tyrosine kinase receptor ,is a growth factor receptor belonging to the proto-oncogene met family and has been proved to display abnormal expres?sion in many types of tumors. The RON receptor is activated by binding to the ligand macrophage stim?ulating protein,overexpression of the receptor,variants of the proto-oncogene and by point mutations of the kinase region. The downstream transduction of RON by mitogen-activated protein kinases and phosphoinositide3-kinase signaling pathways can help regulate the proliferation,apoptosis,migration and invasion of tumor cells. A better understanding of the mechanisms and related signaling pathways of RON activation in tumor progress and development will provide more information for the RON-based target therapy.

This research adopted silt as the sample,and the five highest hydrogen production performing strains contained in the sample were isolated. The strain whose hydrogen production was the highest was identified as Enterobacter cloacae by the analysis of 16S rDNA sequencing and comparison. It is showed by Plackett-Burman Experimental Design that only glucose,citric buffer and reducing agent had significant effects on hydrogen production by Enterobacter cloacae FML-C1. The path of steepest ascent was undertaken to approach the optimal response region of those three factors. Central Composite Design(CCD) and Response Surface Methodology(RSM) were employed to investigate the interaction of the variables and to ascertain the optimal values of the factors,which finally led to the maximum hydrogen production(VH2) . The theoretical optimal medium conditions were:glucose 21.5 g/L,citric buffer 13.6 mL/L,reducing agent10.0 mL/L. The five tentative tests matched this model well. The final VH2 was up to 2347.4 mL/L,which was 127.42% enhanced in comparison to the original. The result shows that PB experiment design and RSM analytical method work well in selecting factors which have significant influences on the hydrogen production and,moreover,achieve the ideal optimal result.

Strains from the cellulose-containing environment were collected. Primary screening(by filter-paper Hutchison solid culture medium and sodium carboxymethylcellulose solid culture medium) and reelection(by filter-paper inorganic salt culture medium and sodium carboxymethylcellulosc Congo red coltnre medium) indicated that five strains obtained were best suited for high performance cellulose degradation. Determination of sodium carboxymethylcellulose activity(CMCA) and filter paper activity(FPA) was accomplished for each of the five. The strongest of the five in CMCA and FPA was applied to the production of cellulose bioethanol by separate hydrolysis and fermentation(SHF) and simultaneous saccharification and fermentation(SSF) respectively.

Objectives:In this study,the effects of glutamine(Gln) and branched chain amino acids(BCAA) enriched formulas on free radical metabolism and immunity in traumatized rats were investigated. Methods:After injury,twenty one male Wistar rats were randomly divided into three groups,and fed with rations containing casein,a commercial amino acids(17AA),and a new amino acids formula(20 AA) respectively.The rations were isonitrogenous and isocaloric.Before operation and on days 3,7,14 postoperation,body weight,dietary intake,the concentrations of MDA,the activities of SOD in plasma were measured.At last,the animals were killed,the hydroyproline and spleen lymphocyte blastogenesis were determined. Results:①After injury,body weight of rats were reduced significantly,the concentrations of MDA in plasma were increased,while the SOD activities were decreased. ②Compared with 17AA group, the levels of hydroyproline in sponge were increased in 20AA group.③There were better effects of reducing plasma MDA levels and enhancing plasma antioxidase activities in 20 AA group than 17 AA group.④The weight of thymus and spleen and spleen lymphocyte blastogenesis were more obviously increased in 20AA group than in 17AA group. Conclusions:The new amino acids preparations can increase the antioxidase activities,enhance immunity and promote wound healing.
