Objective To study the characteristics of pharmacokinetics and pharmacodynamics of insulin dry powder inhalation and its relative bioavailability as compared with subcutaneous injection of regular insulin. Methods In this open,single-center,randomized,two-period,cross-over,euglycemic glucose clamp study,18 healthy volunteers(14 men and 4 women),aged(24.9?1.7)years,with body mass index(20.6?1.2)kg/m~2, received the insulin dry powder inhalatin(80 U)or regular insulin(15 U)subcutaneous administration.The blood samples of this study at 0,20,30,40,50,60,70,80,90,100,110,120,135,150,165,180,195, 210,225,240,270,300,330,360,390,420,450 and 480 rain were taken for serum insulin measurement, meanwhile,glucose infusion rates(GIR)were determined per 5 minutes over a period of 8 hours.Results The C_(max)were(57.9?17.8 vs 114.5?29.7)mU/L(tested vs reference preparation),T_(max)were(46.7?45.6 vs 107.8?33.7)min,GIR_(max)were(3.35?0.98 vs 5.17?1.75)mg?kg~(-1)?min~(-1)and T_(GIRmax)were(88.3?17.0 vs 151.9?34.6)min.The relative bioavailability was(10.26?2.25)%,and the relative bioefficacy was(14.33?7.26)%.Conclusion The study shows that insulin dry powder inhalation is absorbed via lungs and its action sets in earlier than that of the regular insulin injected subcutaneously.These pharmacokinetie and pharmacodynamic data may provide a reliabe guide for further clinical trial.

Objective To investigate the effects of osteopontin (OPN) antisense oligodeoxynucleotide (AS-ODN)on OPN mRNA expressions and adherence to collagen gel of rat renal mesangial cell line (1097). Methods One AS-ODN complementary chain to rat OPN cDNA sequences was designed and synthesized. All nucleotides of different kinds of oligodeoxynucleotide (including antisense, sense and mismatch sense) were modified with phosphrothioate. All the ODNs were mixed with cationic liposome(DOTAP) respectively. The cultured 1097 cells were incubated with different concentration of ODN at 37t for 48 hours, then total RNA was extracted from cultured cell line with Trizol reagent. OPN mRNA expression was detected with RNA dot blot and RT-PCR. The cell adhesion ability was measured with collagen gel attachment lest. Results OPN mRNA expression of mesangial cells was higherly upregulated in the medium with calf serum compare to that in the medium without serum. AS-ODN could suppress the expression of OPN mRNA in mesangial cells with dose-dependent and its lowest inhibitory concentration was 2. 5 ?mol/L, but mismatch ODN or sense ODN have no inhibitory effects on the OPN mRNA expression of mesangial cells even if at a high ODN concentration of 30 ?mmol/L. AS-ODN-treated cells weakly adhered to the collagen gel and could be easily detached off. The mesangial cells treated with mismatch ODN or sense ODN still had a good adherent ability to collagen gel. Conclusions Calf serum can induce rat renal mesangial cells higherly expressing OPN mRNA. Osteopontin antisense oligodeoxynucleotide can specifically suppress mesangial cells OPN mRNA expression and adhension to collagen gel.

Objective To investigate the correlation between angiotensin converting enzyme(ACE) gene polymorphism and kawasaki disease(KD).Methods A 287 bp Alu fragment in intron 16 of the ACE gene was used as insertion(I)/deletion(D) polymorphism marker. The ACE genotype of 28 children (10 children complicated coronary dilataltion) with KD and 35 healthy controls were detected by polymerase chain reaction (PCR), and ACE concentration in blood serum was measured by ultraviolet-spectrophotometer assay.Results 1.The ACE concentration was significantly higher in KD group than that in healthy control group(P

0.05),but there were significant difference between the two groups from 12 hours to 48 hours after operation(all P

Objective To find out the associated effect of intrauterine infection and interuterine asphyxia to fetal rat′s brain damage,cell apoptosis,and expression of glial fibrillary acidic protein(GFAP).Methods Pregnant rats of gestation 18 days were randomly divided into four groups:1.NS plus sham operation,2.intrauterine infection,3.intrauterine asphyxia,4.intrauterine infection plus intrauterine asphyxia.The fetal rats′ brains were taken out 72 h after different disposal and given HE coloration,immunohistochemistry of TUNEL and GFAP,respectively.Results The level of brain cell edema and tissue disorganization of group intrauterine infection plus intrauterine asphyxia were more serious than those of group intrauterine infection or group intrauterine asphyxia.TUNEL and GFAP had the same results:The number of positive cells in group intrauterine infection plus intrauterine asphyxia more than that in group intrauterine infection,and which in group intrauterine asphyxia more than that in group NS plus sham operation.There was significant difference between the first three groups and the group NS plus sham operation(P=0).There was also significant difference between group intrauterine infection plus intrauterine asphyxia and group intrauterine infection or group intrauterine asphyxia(P=0).Conclusions Both intrauterine infection and intrauterine asphyxia may induce premature rat brain damage,the association of intrauterine infection and intrauterine asphyxia may aggravate the degree of fetal rat brain damage,also increase the number of apoptosis cell and the expression of GFAP.
