Objective To investigate the putative relationship between peroxisome proliferators activated receptor gamma (PPARγ) and nuclear factor (NF)-κB in cerulein-treated pancreatic aeinar AR42J cells. Methods The AR42J cells were allocated to control group, pioglitazone group (treated with 40 μmol/L of pioglitazone), pioglitazone + cerulein group (treated with 40 μmol/L of pioglitazone+ 10~(-8) mol/L of cerulein) and pioglitazone + cerulein + PPARγ antagonist (GW9662) group (treated with 40 μmol/L of pioglitazone + 5 μmol/L of GW9662 + 10~(-8) mol/L of cerulein). Activity of NF-κB and PPARγ expression were detected 30 minuts after stimulated by cerulein with or without the presence of pioglitazone. The protein expressions of NF-κB and PPARγ, antibody to IκBα phosphorylation, the differential expression between IκB kinase (IKK)β and IκBa, the IKKβ activity as well as changes of pIκBa were examined by Western blotting. The nuclear accumulation of NF-κB (p65 and p50 subunits) was determined by immunofluorescence and Western blotting. The interaction between NF-κB p65 and IκBα was observed by immunopreeitation. Results Treatment of AR42J cells with pioglitazone attenuated cerulein induced cytosolic activity of IKK protein (1.6 : 3.7)or IκBa phosphorylation (0.9 : 1.5), strengthened the integration of IκBα and NF-κB (0.8:0.3), inhibited transcription activity of p50 and p65 NF-κB dimer and nuclear accumulation (P<0.01). Adversely, the inhibitory effect of pioglitazone on NF-κB activity induced by cerulein was almost reversed by GW9662 (P<0.05). Conclusion These findings provide evidence for the involvement of PPARγ in the activity of NF-κB in cerulein treated AR42J cells.

Objective To investigate the effects of pioglitazone,a peroxisome proliferation activated receptor(PPAR)γ agonist on oxidative stress process and the therapeutic effects on severity of acute pancreatitis(AP).Methods Thirty male Sprague-Dawley rats were randomly divided into five groups with 6 in each:control group,eerulein plus pioglitazone group,cerulein group,cerulein plus vehicle group,cerulein plus pioglitazone and GW9662 group.Rats were sacrificed at 30 min after the induction of pancreatitis.Pathologic changes of the pancreas were observed under light microscope.The ratios of pancreatic wet/body weight of rat were determined in each group.Serum amylase,pancreatic nitric oxide synthase(NOS),inducible nitric oxide synthase(iNOS),malondialdehyde(MDA),and myeloperoxidase (MPO)were determined by chromometry.Results The serum amylase,pancreatic wet/body weight and the score of pathologic damage increased after the induction of pancreatitis,AP samples were characterized by increased pancreatic MDA,MPO,NOS and iNOS(P＜0.01).Pioglitazone(20 mg/kg and 40 mg/kg)exhibited a protective effect against oxygen free radicals reflected by lower serum amylase,less severe pancreatic lesions,normal pancreatic MDA,MPO and NOS levels(P＜0.05).GW9662 reversed the effects against oxidative stress of pioglitazone(40 mg/kg)(P＜0.05).Conclusions Pretreatment with pioglitazone may exert its therapeutic effect on AP by lowering pancreatic oxidative free radicals and reducing pancreatic tissue infiltration of neutrophils.

Objective To analyze the changes of distribution and drug resistance of isolated pathogens for ventilator-associated-pneumonia (VAP) in seven intensive care units from January 2013 to December 2015,so that provides information for clinical antibiotic treatment.Methods Collected the patient records diagnosed with VAP to get the distribution and drug resistance of isolated pathogens for VAP in ICU from January 2013 to December 2015.Compared the distribution of isolated pathogens for VAP among three year with Chi-square tests,and compared the drug resistance of main isolated pathogens with Nonparametric tests.Results 177 patients were diagnosed with VAP from January 2013 to December 2015.A total of 192 strains of pathogens were isolated from the VAP patients in ICU.Among which the gram-negative bacteria were dominant.It took up 90.6％.There was no significant statistical difference for the distribution of pathogens (x2 =2.372,P=0.668＞0.05).Analyzed the drug resistance rate and trends for the primary pathogens like Acinetobacter Bauman,Pseudomonas aeruginosa and Staphylococcus aureus,among which,the drug resistance of Acinetobacter Bauman from 2013 to 2015 made statistical difference.Conclusion The major pathogen isolated from VAP patients was gram-negative bacteria from January 2013 to December 2015,especially for Acinetobacter Bauman.Drug resistance of Acinetobacter Bauman was serious.Should administrated appropriate to treat the VAP infection resulted from Acinetobacter Bauman.

Object To investigate the effects of ultra-fine powder technique and granularity of pellets on dissolution rate in vitro. Methods The dissolution rate of ultra-fine ERMIAO PILL with different granule diameters in vitro was measured and compared with the index of berberine by UV spectro-photometry. Results The dissolution parameters T 50 and T d of four kinds of ultra-fine ERMIAO PILL are 61.60, 19.48, 17.84, 8.97 min and 102.3, 33.29, 26.98, 14.77 min, respectively. Those of general powder ERMIAO PILL with granule diameter of 2.4 mm are 89.61 and 155.68 min. Conclusion The dissolution rate of ultra-fine powder is quicker than that of general powder, and the rate increases with the granularity of PILL decreasing.

AIM:To investigate the effect of ?-cyclodextrin inclusion on transdermal absorption of volatile oil in lilac-cassiabark Gel. METHODS: The release test of two kinds of lilac-cassiabark Gel(gel A without ?-cyclodextrin inclusion and gel B with ?-cyclodextrin inclusion) was assayed with Franz diffusion cell with the help of the cumulative amount of eugenol in unit area in vitro.

Objective To investigate the pharmacokinetics ( PK ) and pharmacodynamics ( PD ) processes of rabeprazole in inhibiting gastric acid secretion with the combined PK-PD model. Methods A total of 10 healthy volunteers were given a intravenous infusion of 20 mg rabeprazole over a 30-min period. The concentration of rabeprazole in the plasma at different time points was detected by HPLC,and the PK parameters were calculated by DAS 2. 0 software. At the same time the intragastric pH was monitored over 24 hours to fit the PD parameters with indirect inhibition model. Results The main PK parameters,t1/2,Cmax,and AUC were(60. 5±17. 3)min,(1 299. 1±201. 0)ng·mL-1,and(106. 4±26. 0)mg·min·L-1, respectively.The corresponding PD parameters,Kin,Ke,IC50 and Imax were(8.200±3.362)h-1,(1.080±0.378)h-1,(0.286± 0. 129)mg·L-1 and(6. 93± 2. 15)pH,respectively. Conclusion The PK of rabeprazole in healthy volunteers conforms to one compartment model,and the PD fits the indirect response inhibition model. The equation can effectively establish the relationship between the blood drug concentration and the effect.
