Objective To study the changes of the urinary ?-1 microglobulin and urinary immunoglobulin G(IgG) and to investigate the relationship between these two proteins and the allograft function after renal transplantation.Methods Twenty-nine renal transplant recipients were included in the study.Urinary ?-1 microglobulin and urinary IgG were analyzed at d 1,7,14,21,28 after renal transplantation.The allograft function was evaluated based on the clinical manifestations,laboratory and imaging examinations,and the relationship between urinary ?-1 microglobulin,IgG and serum cretinine(SCr) were analysed. Results Urinary ?-1 microglobulin and urinary IgG correlated with SCr after renal transplantation in one month.Of all the 29 cases,14 experienced allograft function recovery(group A),and 15 failed(group B).Urinary ?-1 microglobulin decreased significantly in group A(P

BACKGROUND: Studies have demonstrated that intermittent high glucose can have a more severe impact on vascular endothelial function in comparison with persistent hyperglycemia.OBJECTIVE: To investigate the effect of intermittent high glucose on the proliferation and apoptosis of endothelial progenitor cells (EPCs) from human peripheral blood in vitro as well as the production of malondialdehyde (MDA) and antioxidant. METHODS: Total mononuclear cells were isolated from human peripheral blood by Ficoll density gradient centrifugation and then the cells were placed on fibronectin-coated culture dishes. After 7 days of culture, the adherent cells were identified as EPCs by laser scanning confocal microscope. The cells were synchronized and then stimulated with glucose 5.5 mmol/L (normal control group), 20 mmol/L (constant high glucose group), and 5.5/20 mmol/L (intermittent high glucose group, 5.5 and 20 mmol/L glucose culture solution was changed every 8 hours) for 72 hours. EPCs proliferation and apoptosis was measured by MTT assay and flow cytometry, respectively. The content of MDA and the activity of superoxide dismutase (SOD) in culture solution were detected with colorimetry.RESULTS AND CONCLUSION: After EPCs were exposed to constant high glucose (20 mmol/L) and intermittent high glucose (5.5/20 mmol/L) for 72 hours, proliferated cells were significantly reduced and the apoptosis rate was significantly increased compared with those exposed to normal glucose (P < 0.01). Furthermore, there was a significant increase in MDA contents as well as a significant reduce in SOD activities in the constant high glucose and intermittent high glucose group (P < 0.01), especially in the latter group. These findings indicated that both intermittent high glucose and constant glucose could inhibit the proliferation and promote the apoptosis of EPCs; however, intermittent high glucose appears to worsen the effects on EPCs. This is maybe due to the increased oxidative stress.

Objective To explore the effects of atorvastatin and valsartan on high glucose-induced human umbilical vein endothelial cells (HUVECs) injury.Methods Cultured HUVECs were divided and assigned to 9 groups:normal control group,mannitol control group,high glucose group,low dose atorvastatin group (0.1 μ mol/L),medium dose atorvastatin group (1 μmol/L),high dose atorvastatin group (10 μ mol/L),low dose valsartan group (0.1 μmol/L),medium dose valsartan group (1 μmol/L),and high dose valsartan group (10 μmol/L).H UVECs were pretreated with or without 30 mmol/L glucose plus various concentrations of atorvastatin and valsartan (0.1,1,10 μmol/L) for 16 hours and then incubated with 5.5 mmol/L glucose for 6 days.The levels of vascular cell adhesion molecule 1 (VCAM-1),monocyte chemotactic protein 1 (MCP-1),and plasminogen activator inhibitor 1 (PAI-1) in the culture supernatant were measured by enzyme-linked immunosorbent assay.Results Compared with normal glucose group,hyperglycemia memory increased the levels of VCAM-1,MCP-1,and PAI-1 (all P＜0.05),which were still maintained at high levels even after withdrawal of high glucose.Atorvastatin and valsartan treatment decreased the levels of VCAM-1,MCP-1,and PAI-1 (all P＜0.05).Conclusion Atorvastatin and valsartan may lower the secretion of VCAM-1,MCP-1,and PAI-1,and prevent high glucose memory-induced injury to endothelial cell.

Objective To evaluate the effects of small dose of antithymocyte globulin(ATG)and zenapax in the induction therapy for kidney transplant recipients.Methods A series of 150 cadaver-donor kidney transplant recipients were randomly divided to 3 groups,ie,small dose of ATG group(total dose,2.1 -3.0 mg/kg;n=72),zenapax group(50mg,on the first and 14th d after operation;n=15)and controls without induction therapy(n=63).Follow-up was 6 months.The rates of acute rejection,delayed graft func- tion(DGF)and pulmonary infection were statistically compared among the 3 groups.Results During a 6-month period,in ATG,zenapax and control groups,acute rejection episodes occurred in 4 cases(5.5%), 1(6.7%)and 10(15.9%),respectively;DGF occurred in 3(4.2%),0 and 8(12.7%),respectively;pul- monary infection occurred in 4(5.1%),1(6.7%)and 3(4.8%),respectively;leucocytopenia occurred in 3(4.2%),1(6.7%)and 5(7.9%),respectively;thrombocytopenia occurred in 2(2.8%),1(6.7%)and 5(7.9%),respectively.Conclusions In the early stage of kidney transplantation,small dose of ATG and zenapax can be the optimal choice for induction therapy.

The compounds (8R23, 9R221 , 9R6222, 10R221 , H1105) extracted from the soft coral, with unsaturated lactone, showed antitumor effect on EAT, IC50 was 18. 6,85. 8,67. 8,3d. 9, 3.05umol. L-1, respectively; IC50 on S180 was 10. 7,44. 4,30. 9,9. 95,2. 4umol. L-1, respectively. 8R23, 10R221 obviously increased the level of cAMP in the EAT cell. 8R23, 10R221 , III 105 also inhibited DNA synthesis of the EAT cell.These results indicated that these compounds might have antitumor effect, but the mechanism was unknown.

Objective To explore the effects of electro-acupuncture combined with surface gastric pacing on gastrointestinal dysfunction for patients with spinal cord injury (SCI).Methods Seventy-five SCI patients with gastrointestinal dysfunction were divided randomly into an electro-acupuncture group (group A),a gastric pacing treatment group (group B) and a group for which electro-acupuncture was combined with gastric pacing (group C).There were 25 cases in each group.Members of group A were given 30 minutes of electro-acupuncture per day ; those of group B had 30 minutes of gastric pacing treatment twice per day ; group C was provided with both 30 minutes of electro-acupuncture and one 30-minute gastric pacing treatment per day.All of the interventions lasted ten days.Before and after the treatment,all patients were assessed using a clinical symptoms score and with electrogastrograms,and any adverse effects were observed.Results There was a significant improvement in upper abdominal pain and epigastric discomfort,bloating and early satiety,nausea,vomiting,as well as belching and loss of appetite in each group after treatment.Before treatment there was no significant difference in the average clinical symptom scores of the three groups.After treatment the values had decreased,and those of group C were significantly lower than group A or B.The average scores of groups B and A were not significantly different.The electrogastrogram results showed than after treatment there was significant improvement in N％ and T％ in groups A and B,and also significant improvement in N％,B％ and T％ in group C compared to before treatment.Group C's improvements were all significantly greater than those observed in groups A and B.Conclusion Electro-acupuncture or gastric pacing alone can give some improvement in gastrointestinal function and its electrophysiological indicators,but their combined effects are better than when either is used alone.

Objective To explore the prognostic value of ventricular wall motion score (WMS) and left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction (AMI) combined with heart failure (HF) in the recent 12 months Methods We selected hospitalized AMI patients in our department from Jan. 2014 to Nov. 2014. Cardiac ultrasound was performed to detect WMS and LVEF within 48 hours and during the 6?month follow?up period and the occurrence of HF was recorded. Results Totally 127 AMI patients were recruited, including 20 cases combined with HF. The WMS was higher in HF group than those in non?HF group (23.55 ± 3.73 vs 20.11 ± 3.13, P<0.01), while the LVEF in HF group was lower than those in non?HF group (48.77 ± 8.08 vs 56.99 ± 5.17, P<0.01). Multiple logistic regression analysis revealed that WMS and LVEF were both independent predictors of HF in the recent 12 months (P < 0.05). The prediction effect of WMS ROC curve area was 0.81 (P < 0.01) , and LVEF 0.76 (P < 0.05). WMS and LVEF combined assessment area under ROC curve was 0.82 (P < 0.01). Conclusion WMS and LVEF are independent predictors of HF in patients with AMI in the recent 12 months and the combined application of WMS and LVEF can significantly improve the prediction effect.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.
