Objective To investigate effect of tacrolimus on renal function, blood lipids, cytokines and peripheral HMGB-1 and NF-κB in nephrotic syndrome patients.Methods From January 2012 to January 2014 in the Fifth Affiliated Hospital of Zhengzhou University, 127 cases of patients with nephrotic syndrome were included based on random number table, and divided into two groups (n=65) and control group (n=62).Control group with conventional symptomatic treatment, observation group in combination with tacrolimus treatment on the basis of control group, which were treated for a total of two courses, eight weeks for a course of treatment.Serum creatinine and blood urea nitrogen levels, TG, TC, HDL-C, LDL-C levels, serum IL-1, TNF-αlevels and serum HMGB-1 and NF-κB levels were evaluated.Results The serum creatinine and blood urea nitrogen levels after treatment was significantly lower than that of control group, respectively ( P<0.05 ) .TG, TC and LDL-C levels after treatment in observation group was significantly lower than that of control group respectively (P<0.05).Serum IL-1 and TNF-αlevels after treatment in observation group was significantly lower than that of control group respectively (P<0.05).Serum HMGB-1 and NF-κB levels after treatment in observation group was significantly lower than that of control group respectively (P<0.05).Conclusion Tacrolimus can reduce blood lipid levels, inflammatory reaction and serum HMGB-1, NF-κB levels in nephrotic syndrome patients, and significantly improve renal function.

Objective To investigate the retinal toxicity and verify the safe dose of intravitreal injection of nonsteroid anti inflamatory drug, diclofenac sodium. Methods Twenty eight healthy adult white rabbits were divided at random into 7 groups and received in every right eye the intravitreal injection of a single dose of diclofenac sodium solution ranging from 0.4～1.0 mg/0.1ml respectively,the left eyes were regarded as control ones. Before injection and on the 1st, 3rd, 7th, 14th, 21st, and 28th day after injection the electroretinography on both eyes was examined. On the 28th day after injection the retinas of two rabbits of every group were examined by using light microscopy. On the 10th and 30th day after injection the retinal tissues around the optic nerve disk of two eyes from every group at random were tested by using transmission electron microscopy. Results The ratio of amplitude of b wave of electroretinography in 0.4 mg and 0 5 mg groups had no significant difference from groups before injection,the retinal tissues showed no structural changes in light and electron microscopy examination. The ratio of amplitude of b wave of photoptic electroretinography in 0.6 mg groups in the early stage after injection was markedly reduced ( P

Objective By using ProtEx~(TM) technology to decorate target cells with an exogenous protein and observe its function for immunomodulation.Methods Donor splenocytes were decorated with chimeric SA-FasL protein.The expression of FasL and its impact on other molecules on the surface of splenocytes was detected.Heterotopic rat heart transplantation was performed from inbred WF rat to ACI rat.According to the different donor splenocytes perioperatively injected into recipients,the recipients were divided into 3 groups:SA-FasL group (n=23),SA group (n=20) and control group(n=10).Heart beating was examined by palpation on daily basis,the cessation was regarded as reiection,while surival over 100 days was considered as graft long-term survival.Diabetes models in C57BL/6 mice were induced by intravenous injection of STZ.Islets from BALB/C mice were decorated by SA-FasL protein,islets transplant was performed from BABL/c to C57BL/6 mice.Based on the different treatments of donor islets,recipients were divided into three groups:islet-FasL group (n=21),islet-SA group (n=21) and islet-untreated group(n=14).Rejection was identified while urine glucose was positive and blood glucose value was over 250 mg/ml for consecutive two days.Urine glucose negative over 100 days was regarded as graft long-term survival.Results The mean exDression rate of FasL in splenocytes was 94.49%±4.27% tested by flow cytometry and FasL showed red color 0n the surface of splenocytes by fluorescent stammg.FasL deeoration did not disturb the expression of CD3,CD4,D8,MHC I and CD80.The long-term survival rate o,f heart transplant showed significant difference between tWO groups(SA-FasL:70% vs SA:25%,P<0.05).67% FasL-decorated islets had normal function 30 days post transplant,and 29%FasL-decorated islets achieved long-term survival,which was significantly differed from the other groups(P<0.05).Conclusion ProtEx~(TM) is a simple,fast,safe and efficient approach for exogenous protein modmcation.Decoration of target cells with Chimeric FasL by this technique plays an umportant role in immunomodulatiorn.

OBJECTIVE:To compare clinical efficacy,safety and economy of urokinase and alteplase each combined with Enoxaparin sodium in the treatment of acute ST segment elevation myocardial infarction (STEMI). METHODS:80 STEMI pa-tients were randomly divided into control group and observation group,with 40 cases in each group. Both groups received Aspirin enteric-coated tablet for antiplatelet aggregation,and Clopidogrel hydrogen sulfate tablet for anticoagulation before thrombolysis. Control group were given urokinase 1 500 000 U added into 0.9% Sodium chloride injection 100 ml,ivgtt,within 30 min;given Enoxaparin sodium injection 7 500 U intramuscularly 12 h after thrombolysis,for 3-5 d. Observation group was given Enoxaparin sodium 60 U/kg,ivgtt,1 mg/ml Alteplase for injection 8 ml with intravenous push,other 42 ml ivgtt within 90 min;continued to receive Enoxaparin sodium with 12 U/(kg·h)micro-pump for 48 h,followed by Low molecular weight heparin calcium injection 5 000 U intramuscularly,bid,for consecutive 5 d. Clinical efficacy of 2 groups were observed,and thrombolytic recanalization situa-tion were observed 30,60,90 and 120 min after thrombolysis. ECG,cost-effectiveness and ADR were also observed. RESULTS:The effective rate of observation group(92.50%)was significantly higher than that of control group(85.00%). The rates of throm-bolytic recanalization in observation group 60,90 and 120 min after thrombolysis were significantly higher than in control group, with statistical significance(P<0.05). Q wave time,Qwave/Rwave and ST segment deviation of observation group after treatment were significantly lower than those of control group,with statistical significance(P<0.05). The total hospitalization cost of obser-vation group was significantly higher than that of control group,with statistical significance(P<0.05);there was no statistical sig-nificance in effective rate and the per unit cost of thrombolytic recanalization rate (P>0.05). The incidence of ventricular aneu-rysm,pericardial effusion,heart failure or cardiac shock,angina pectoris after infarction,severe arrhythmia,death and other as-pects in observation group were significantly lower than in control group,with statistical significance(P<0.05). CONCLUSIONS:Alteplase and enoxaparin thrombolysis therapy is better than urokinase and enoxaparin for STMEI in respects of clinical efficacy, and thrombolytic recanalization with less ADR and better safety;urokinase is cheaper and better than alteplase in cost-effectiveness ratio. Both of them can be used after careful consideration.

Objective To investigate effect of alprostadil on serum levels of inflammatory cytokines and nutritional biochemical indexes in patients with chronic renal failure.Methods According to the random number table, 129 patients with chronic renal failure patients were included in this group and randomly divided into observation groups (n=67) and control group (n=62).Control group were given conventional symptomatic treatment, and the observation group were given alprostadil treatment on the basis of control group with a course of four weeks of both groups.The Scr, BUN, IL-6, TNF-α, CRP, Ca2 +, ALB, P3 +, Hb, RBC, hemorheology changes were compared before and after treatment.Results The Scr, BUN levels after treatment was significantly lower than before treatment (P<0.05), and Scr, BUN levels in observation group after treatment was significantly lower than control group (P<0.05).Serum levels of IL-6, TNF-α, CRP after treatment significantly decreased than before treatment (P<0.05), serum IL-6, TNF-α, CRP after treatment was significantly lower than control group ( P<0.05 ).After treatment, Ca2 +, ALB levels of observation group was significantly higher than control group and P3 +was significantly lower than control group (P<0.05), while there were no significant differences of Hb, RBC.The hemorheology of observation group before treatment was significantly lower than control group ( P<0.05 ) .Conclusion Alprostadil can significantly improve renal function, and the possible mechanism may be associated with reducing serum levels of inflammatory factors and improving blood rheology, which delay progression of chronic renal failure effectively.
