BACKGROUND:To control blood glucose, blood pressure, blood lipids and inhibit the rennin-angiotensin system is the main idea focused on the treatment of diabetic nephropathy, but the curative effect is unsatisfactory. Hemodialysis and kidney transplantation are suitable for serious cases, however, which is restricted because of the limited source of kidneys and high cost. Regenerative medicine research based on stem cells brings a new hope for treatment of diabetic nephropathy. OBJECTIVE:To comprehensively analyze the mechanism underlying different sources of stem cells for treatment of diabetic nephropathy and the clinical implications. METHODS:Papers addressing stem cells for the treatment of diabetic nephropathy were retrieved by computer in CNKI database and PubMed database from January 2005 to August 2013 with the key words“embryonic stem cells, bone marrow mesenchymal stem cells, induced pluripotent stem cells, diabetic nephropathyin Chinese and English. Papers published recently or in journals with high impact factor were selected. A total of 60 papers were included for review. RESULTS AND CONCLUSION:Embryonic stem cells, bone marrow mesenchymal stem cells, induced pluripotent stem cells have the potential to differentiate into renal histiocytes. A large numbers of experimental studies have shown that stem cells transplantation has a positive effect on recovery of injured kidney. Stem celltransplantation can provide a novel therapy for diabetic nephropathy.

Objective evaluate the mechanism that bacteria growing in biofilm always resist to antimicrobial agents,and to provide the theoretical basis for selecting antimicrobial agents in clinic.Methods Model of klebsiella pneumoniae bacterial biofilm were built up with the modified flat-board method and identified with the method staining with AgNO3 and confocal scanning laser microscopy.We used imipenem to induce the ESBLs production of BF bacteria.ESBLs production was performed by the standard disk diffusion method.Results The isolation rate of ESBLs producting strains in klebsiella planktonically planktonically were 20.0%(8/40).The isolation rate of ESBLs producting strains in klebsiella biofilm were 42.5%(17/40).The isolation rate of ESBLs producting strains in klebsiella biofilm being induced by imipenem were 65.0%(26/40).The isolation rate of group A and group B,groupB and group C was different from each other significantly with the statistic method of ?2-test.Conclusion One of the main reasons that klebsiella and escherichia coli resist to antibiotics is the synergetic effect of BF and ESBLs.

Objective To compare the effects of limited fluid resuscitation and aggressive fluid resuscitation in treatment of uncontrolled hemorrhagic traumatic shock,and to improve the cure rate.Methods One hundred and twenty patients with hemorrhagic traumatic shock on the basis of outpatient registration number of single and double were divided into limited fluid resuscitation group(limited group,56 cases) and aggressive fluid resuscitation group (positive group,64 cases),respectively.The preoperative blood lactic acid,base excess,prothrombin time,hemoglobin was compared and the preoperative infusion and the number of patients with death was recorded.Results The preoperative infusion in limited group was significantly less than that in positive group [(1 050 ± 212) ml vs.(2 120 ± 186) ml],the difference was statistically significant (P ＜ 0.01).The mortality rate in limited group was significantly lower than that in positive group [12.50％(7/56) vs.28.12％(18/64)],the difference was statistically significant (P＜ 0.05).The preoperative blood lactic acid,base excess,prothrombin time in limited group were significantly lower than those in positive group [(3.31 ± 0.29) mmol/L vs.(5.78 ± 0.15) mmol/L,(5.42 ± 1.13) mmol/L vs.(9.86 ± 1.21) mmol/L,(11.7 ± 1.9) s vs.(18.1 ± 1.7) s],and the hemoglobin in limited group was significantly higher than that in positive group [(96 ± 18) g/L vs.(83 ± 20) g/L],the differences were statistically significant (P ＜0.01).Conclusions If hemorrhage is not controlled,early limited fluid resuscitation can maintain blood perfusion of vital organs,alleviate acidosis,reduce mortality and creat good conditions for advanced treatment.Limited fluid resuscitation is superior to aggressive fluid resuscitation in operative intervention for patients with uncomtrolled hemorrhagic traumatic shock.

The study is aimed to provide the theoretical basis for exploiting and utilization of salt-alkaline soil and cultivating Belamcanda chinensis. In this study, we exerted exogenous substances SNP, Spd to relieve the damage of the mixing salt-alkaline stress on B. chinensis seedling which is NaCl, Na2SO4, NaHCO3 and Na2CO3 four kinds of salt molar ratio of 9: 1: 9: 1, salt concentration of 100 mmol x L(-1). The result illustrated that high pH stress is a major factor caused the salt-alkaline stress, the interaction between time and the concentration of each, treatment was observed, what is more, there are synergies between the salt and alkali stress. The content of B. chinensis seedling leaves' membrane peroxidation index (MDA, O2-*) and metabolites (soluble protein, soluble sugars, organic acids) are showing an upward trend in varying degrees under 100 mmol x L(-1) salt-alkaline stress. It is effective to reduce the content of MDA and O2-*. and improve the levels of metabolites, in which the SNP (0.05 mmol x L(-1)) and Spd (0.5 mmol x L(-1)) to alleviate damage effects is the best. Therefore we can hold the conclusion that SNP and Spd can effectively mitigate the damage of B. chinensis seedling on salt-alkaline stress, improve the resistance ability of B. chinensis seedling which can provide the scientific basis for the utilization of salt-alkaline soil, and the cultivation of B. chinensis.

Objective To detect the level of Th1 and Th2 type cytokines of peripheral blood CD+3 T lymphocytes in patients with breast cancer, in order to find out the laboratory evidence of tumor immunotherapy. Methods The peripheral blood lymphocytes were stimulated by stimulator in order to enhance expression of cytokines. Specific fluorochrome-conjugated monoclonal antibody combined with antigen. Cytokines were detected by flow cytometry and ELISA. Results Both the cytokines secreted by CD+3 T lymphocytes and serum cytokines showed that the level of Th1 type cytokines such as interferon-?(IFN-?), interleukin-2(IL-2), interleukin-12(IL-12) were significantly lower in patients of breast cancer than those of normal controls. The level of Th2 type cytokines such as interleukin-4(IL-4), interleukin-10(IL-10) were higher in patients of breast cancer than those of normal controls. There was significant difference between them. The level of tumor necrosis factor ? (TNF-?)in patients were significant higher than normal control. Conclusion Th1/Th2 was imbalance in mammary cancer. Th1 type cytokines were inhibited, and Th2 type cytokines were relatively enhanced, so Th1/Th2 shift to Th2. It maybe the mechanism of tumor arising and transferring by immune escaped from immunosurveillance.
