In recent years, nanoparticle as drug carriers have been widely used in the pharmaceutical field. For some poorly soluble drugs or drugs with strong toxicity and side effects, the design of different nano drug carriers can help achieve improved solubility and targeted therapy. The nano targeted drug delivery system can deliver drug specifically to the target sites and realize controlled release of drugs, thereby increasing the bioavailability and efficacy of drugs and reducing the toxicity and side effects. In this paper, the recent progress in studies on the design of nanoparticles, their biological effects, and their application in the field of medicine are reviewed.

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.

50% was defined as significant stenosis. Results A 98.7% (778/788) of the coronary artery segments (vessel diameter ≥1.5 mm) could be visualized by 64-slice spiral CT. Compared with catheter angiography in the detection of coronary stenosis, the overall sensitivity, specificity, positive predictive value, negative predictive value and the accuracy of 64-slice CT coronary angiography were 81.9%, 99.0%, 95.9%, 95.1%, and 95.2% respectively. Overall sensitivity would be 91.8% if corrected methodologically. The sensitivity after methodological correction became 91.8%. Conclusion Sixty-four-slice spiral CT examiniation provides a promising non-invasive approach in detecting coronary stenosis with fairly good accuracy, but can not totally replace catheter coronary angiography yet.

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.

Objective To investigate the change of the fibrin monomer (FM) level in the venous thromboembolic disease (VTE).To compare the diagnostic value of FM combined Wells score with the other detection methods.Methods In this case control study,121 cases were selected from the patients who were from general and orthopeadic surgery (including thrombosis group in 60 cases and non thrombosis group in 61 cases).The patients were assessed by Wells score.From one day before surgery, Plasma d-dimer (D-D) and fibrin monomer (FM) were periodic measured by CP-2000 d-dimer and fibrin monomer.Evaluation the value of d-dimer,fibrin monomer and fibrin monomer combined with Wells score in diagnosis of venous thromboembolic disease.The receiver operation cure(ROC) was drew to determine the diagnostic performance.Results The plasma FM level of patients with VTE in the thrombus group (26.11±38.34) μg/ml is higher than the non thrombus group (6.56±6.81) μg/ml and the control group (2.37±0.89) μg/ml (t=-3.82, t=-4.78,P<0.01);the sensitivity of FM was lower than the D-D (85% vs 93%);then the positive predictive value was lower than D-D (82% vs 87%) (χ2=27.01,P=0.000)but its specificity and negative predictive value (65%) are both higher than D-D (65% vs 44%)(71% vs 62%)(χ2=11.67,P=0.001);the sensitivity,the specificity,the positive predictive value and the negative predictive value of FM combined Wells score are increased (90%,85%,83%,89%)(χ2=20.95,χ2=16.65,P<0.01).The increased level of FM is earlier than imaging changes, and the elevated of plasma D-D is not obvious in a certain period of time.Conclusions The sensitivity and specificity of FM combined with Wells′ score is higher in the diagnosis of VTE, its prediction value in the diagnosis of VTE is higher.The FM level can be changed in the early stage of VTE, which has a certain value of early diagnosis.
