Methods A total of 80 renal transplant recipients during the same period were divided into treatment and control groups, each group containing 40 patients. There were no difference between the two groups in treatment regime except the preoperative single administration of zenapax in the treatment group. Results Acute rejection rate was significantly lower in the treatment group(7.5%) than the control group(25%) within 6 months after kidney transplantation(P

Objective To investigate the effect of Kang Shueling gel on the degree of inflammation in the patients with Ⅱ degree burns. Methods 86 patients with Ⅱ degree burns from July 2014 to July 2016 in our hospital were divided into the control group and the experimental group by lottery method with 43 cases in each group. The control group was treated with silver sulfadiazine, the experimental group was treated with Kang Shuling gel, the two groups of clinical curative efficacy, inflammatory factors, visual analogue scale (VAS), wound healing rate and wound healing time, wound infection rate and adverse drug reactions were compared. Results After treatment, the total effective rate of the experimental group was 95.34% higher than that of the control group 72.09%, the difference was statistically significant (P<0.05). The tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6) levels of the experimental group was lower than the control group, the difference was statistically significant (P<0.05). The VAS of the experimental group was lower than the control group, the difference was statistically significant (P<0.05).The wound healing rate of the experimental group was higher than that of the control group on the seventh day and the fourteenth day, and the wound healing time was better than that of the control group, the difference was statistically significant (P<0.05). The wound infection rate of the experimental group was lower than that of the control group (P<0.05). There was no significant difference in adverse drug reactions between the two groups. Conclusion The curative effect of Kang Shuling gel on the treatment of Ⅱ degree burns patients worthy of affirmation, could reduce serum inflammatory factors level.

Objective To explore the effect of hypoxia-inducible factor 1α(HIF-1α)in pathological scar and its specific mechanism,and the therapy target of pathological scar.Methods Real time PCR and Western blot was used to test the expression of HIF-1αin normal tissue and pathological scar,meanwhile to detect the effect of hypoxic environment on the expression of HIF-1α.Fibroblasts activity in pathological scar and normal tissue under different oxygen concentration(20%,10%,5%,2% and 1%)was determined by MTT method.Determine the different expression of HIF-1αmRNA and protein in normal environment(20% oxygen) and hypoxic environment(5%oxygen).The changes of the number of fibroblasts after the silence of HIF-1αby HIF-1αshRNA virus using flow cytometer.Results The Real time PCR and Western blot results showed that the expressions of HIF-1αmRNA and protein in fibroblasts of pathological scar was significantly higher than that in normal tissue(P<0.05),and the activity of the keloid fibroblasts in hypoxia environment(5%,2% and 1%)was also higher than that in normal tissue(P<0.05).The expressions of HIF-1αmRNA and protein in keloid fiber cells were higher in hypoxia environment(5% oxygen)than those in normal environment(20% oxygen),but when silence the expression of HIF-1αin keloid fibroblasts,the apoptosis of fibroblast in hypoxia environment(5%oxygen)were significantly higher than control group[(0.021 ±0.001)%vs.(3.739 ± 0.039)%,P<0.05].Conclusion HIF-1αincreases significantly in the pathological keloid fibroblasts and could promote the proliferation of fibroblasts and its vitality,which could accelerate the formation of pathological scar.

Objective To investigate the risk factors of insulin resistance(IR)and its relationship with metabolic syndrome in patients after lenal transplantation.Methods 133 renal transplant redpients who had not undergone acute rejection,calcinurine intoxication and severe infection,and had normal renal function and no proteinuria at the 6th month post-transplantation,were involved in the study.They had a history of chronic glomerulonephritis as the primary disease of ESRF but rio diabetes mellitus.108 recipients(CsA group)were treated with CsA,mycophenolate mofetil(MMF)and prednisone after transplantation,19 recipients(Tac group)with tacrolimns(Tac),MMF and prednimne,and 6 recipients with Simlimus,respectively.One year later,blood and urine biochemical tests and physical examinations were performed on the recipients,and HOMA calculated.200 cormnunity residents were randomly selected as controls.Results The incidence of MS in the recipients was 33.1%,significantly higher than controls(15.0%).There was no significant difference in the incidence of obesity and overweight between recipients(29.3%)and controls(37.5%).In recipients with obesity or overweight,the insulin-resistance level and urine albumin level,and the incidence of MS weree significantly higher than those without obesity or overweight.The insulin-resistance level in Tac-treated recipients was markedly higher than CsA-treated recipients,and there was a positive correlation between the blood concentration of Tac and insulin-resistance levd.Microalbuminufia-positive recipients had higher insulin-resistance levels.Metabolic syndrome-complicating recipients had higher insulin-resistance levels than those without metabolic synawme,and higher insulinresistance levels existed in recipients with hypertriglyceridemia or hyperchcllesterolemia,hypertension.Conclusion Obesity or overweight,Tac(especially when blood concentration was higher)were risk factors resulting in imulin-resistanee in kidney transplant recipients.It is suggested that insulin-resistance might be involved in the pathogenesis of metabolic syndrome including hypertrglyceridmaia,hypercbolestemlemia and hypertenion.

Objective To establish a method based on repetitive protein sequences and linear B cell epitope to predict and screen specific peptides of Plasmodium vivax. Methods A P. vivax protein sequence database was reconstructed based on Plas-moDB data,and a customized software for searching of repetitive sequences was used to count the repetition times of each 16 aa peptide in the whole database,and the highly repetitive peptides were chosen to predict the potential linear B cell epitopes. The re-petitive peptides with P. vivax specificity were selected as candidate antigen peptides to synthesize and to couple with KLH carrier protein for immunizing BALB/c mice. After the immunization,the antibody titers of the immunized mice were detected. Results The repetitive information of 16 aa peptides was analyzed by screening of the total 5 432 peptide sequences in the P. vivax data-base. A total of 22 peptides were identified as candidate peptides from the top 1 000 repetitive peptides by linear B cell epitope pre-diction on the BcePred website. Through clustering analysis and similarity comparison,five potential P. vivax specific peptides were selected,synthesized and then coupled with KLH to immunize the mice. The antibody titers of the immunized mice induced by the 5 peptides were all above 1:9 000. Conclusion The method for predicting and screening of specific peptides of P. vivax based on repetitive protein sequences and linear B cell epitope has been established successfully,and all the 5 peptides obtained by the method can induce the high titer antibody in mice.
