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 analyze and summarize the skills and complications of extracorporeal membrane oxygenation( ECMO) cannu-lation and vein intubation. Methods The clinical data of 21 patients of V-A or V-V ECMO in our hospital from January 2009 to July 2014 were analyzed retrospectively. And the techniques of different catheter sites were summarized. Results Three cases were successfully insert-ed catheter by jugular vein puncture with one time. Four patients with ascending aorta intubation died from uncontrolled severe hemorrhage. Eight peripheral catheter site had a small amount of bleeding,with no more bleeding after pressurized bandage. There were no complications like bleeding, hematoma, hemothorax and pneumothorax in the period of ECMO. Conclusion In the process of the ECMO catheter, the standardized operation could reduce the incidence of serious complicaions including bleeding.

Objective To discuss and evaluate the value of insertion of inferior vena cava filter in treating lower extremity deep venous thrombosis(DVT).Methods Inferior vena cava filters were placed in 46 patients with lower extremity DVT prior treatment,20 in which were treated by therapy with anticoagulation and thrombolysis,and therapy with pressure gradient,and the other 26 patients by operation and thrombolysis therapy,and therapy with pressure gradient.Whether patients occurred pulmonary embolism was observed and the form and site of filters were monitored by periodic fluoroscopy.Results Inferior vena cava filters were placed successfully in all patients,38 cases were implanted permanence inferior vena cava filter,8 cases were implanted temporary inferior vena cava filter.Symptoms and signs of DVT disappeared or remitted in 44/46 patients after treatment.None of pulmonary embolism was occurred.Follow up 2-24 months(average 13 months) for 36 cases with permanence inferior vena cava filter,there was no complication of the filter and pulmonary embolism occurred.Conclusions The method of inserting inferior vena cava filter is simple and safe,which can prevent pulmonary embolism effectually to offer sufficient safeguard for the treatment of DVT.

Objective To study the relationships between serum intedeukin-18(IL-18)and resistin for predicting intraamniotic infection.Method Serum levels of IL-18 and resistin were measured in 43 pregnant women with intraamniotic infection (infection group)and 40 normal pregnant women(control group).Results The level of IL-18 in infection group[(38.7±10.4)μg/L]was higher than that in control group [(23.5±5.6)μg/L],there was significant difference between two groups (P＜0.01).The level of resistin in infection group[(24.84±5.32)μg/L]was higher than that in control group[(17.3±5.15) μg/L],there was significant difference between two groups(P＜0.01).The levels of resistin and IL-18 were correlated in pregnant women with intraamniotic infection(r=0.61,P＜0.01).Conclusion Detecting the levels of IL-18 and resistin in pregnant women can identify intramnniotic infection.

Objective This research is to observe the treatment effects of hip bath and oxygen blowing on severe neonatal diaper rash.Methods 289 neonates with severe diaper rash were randomly divided into three groups.91 cases in the flat tube group,102 cases in the round tube group and 96 cases in the control group.Three groups of neonates were cleaned on the hips and perineuma after poops and then dried with wet tissues and Mupirocin Ointment.The control group was treated with the above-mentioned method.The oxygen blowing groups were treated with hip bath of 1:5000 chameleon solution twice a day.Blowing the hips with oxygen five minutes every time after hip bath.The method of blowing oxygen was that oxygen humidifying containers as normal oxygen aspiration facilities was not filled with water,whose oxygen flowing volume standed at 10 L/min and whose tube blew at the afflicted parts until being dry.The oxygen blower held the oxygen exit and blowed at the afflicted parts in the round tube group and the oxygen blower flattened the oxygen exit and blew at the afflicted parts in the fiat tube group.The treatment effects will be compared among the three groups four days later.Results The cure period of the round tube group was obviously shorter than that of the control group,and the cure period of the fiat tube group was remarkably shorter than that of the round tube group.The total effective rate in the round tube group was obviously higher than that of the control group and the total effective rate in the fiat tube group was obviously higher than that in the round tube group.The difference had a statistical significance.Conclusions The treatment effects for the severe neonatal diaper rash with hip bath and oxygen blowing are remarkable and the oxygen blowing effects with fiat tubes are better than those with round tubes.
