To investigate the rat intestinal absorption of stearic acid-octaarginine (SA-R8) modified solid lipid nanoparticles containing paclitaxel (SA-R8-PTX-SLN), compared with the commercially available preparation of PTX (Taxol) and PTX-loaded solid lipid nanoparticles (PTX-SLN), the in situ intestinal absorption of SA-R8-PTX-SLN was investigated by means of single-pass rat intestinal perfusion technique. The absorptions of the preparations were investigated at different intestinal segments, different drug concentrations and in the presence of P-glycoprotein inhibitor (verapamil). The results showed that PTX could be absorbed at each intestinal segment and the three preparations all showed maximum absorptions at the duodenum. The cumulative absorptions of three preparations at each intestinal segment appeared SA-R8-PTX-SLN > PTX-SLN > Taxol (P < 0.05). SA-R8-PTX-SLN showed a liner absorption manner at the duodenum in the examined drug concentration range. The cumulative absorptions of Taxol and PTX-SLN were significantly promoted after the addition of P-glycoprotein inhibitor (verapamil) into the preparation (P < 0.05), but absorption of SA-R8-PTX-SLN existed no significantly difference compared with the preparation without verapamil (P > 0.05). SA-R8 and SLN might both effectively improve the oral absorption of PTX in the intestinal tract.

Objective To discuss the relationship between chronic bronchitis and meteorological conditions in Nanjing. Methods Took the record of the recrudescing time of 200 old chronic bronchitis patients for a year. The correlation between the changing of air temperature and pressure and the monthly chronic bronchitis recrudescing in a year was analyzed. The main meteorological conditions by which recrudescing were affected in different season were selected with multiple stepwise correlation analysis. Results There were chronic bronchitis patients recrudescing the whole year, but the most were in winter and the least in summer. The most recrudescing happened in December and April, and the least in May and July. The meteorological factors that affected chronic bronchitis patients recrudescing were air temperature, pressure and wind speed. The relative coefficient of case numbers between 24 hours variations of air temperature and pressure was 0.5762(P=0.0499) and 0.5841(P=0.0461), respectively. Conclusion The steady meteorological conditions are not good for recrudescing of chronic bronchitis patients. And temperature descent and high air pressure are the main meteorological factors that induce chronic bronchitis recrudescing.

Arapidscreeningmethodforthedeterminationofcarbamatepesticides(CBPs)residuesin vegetables by measuring acetylcholinesterase ( AChE ) inhibition rate using electrospray ionization mass spectrometry ( ESI-MS ) has been established. After pretreatment by QuEChERS method, sample solution reacts with AChE using acetylthiocholine as substrate. AChE inhibition rate was calculated by determination of the conversion of substrate to product ( thiocholine) using ESI-MS. The temperature, time and concentration conditions of enzymatic reactions have been optimized. The relationship between the concentration of 10 kinds of common CBPs and AChE inhibition rate was researched. Matrix effects of real vegetables were studied. The limit of detection ( LOD) , which was measured by 3 times of enzyme inhibition rate of pesticide-free vegetable samples, was 0. 01-0. 05 mg/kg. The results showed that the method was better than the current national standard method of china for rapid screening of pesticide residues and fully meet the requirements of maximum residue limits( MRL) for pesticides in food of national food safety standard. False positive results were avoided effectively due to its good ability of resistance matrix interference. The reliability was proved by analyzing vegetables with liquid chromatography-tandem mass spectrometry. The method is simple, rapid, sensitive, reliable, and can be used for the rapid, high-throughput screening of CBPs in vegetables.

Objective To explore the value of the ultrasound contrast agent in conjunction with advanced contrast imaging techniques in the evaluation of the renal cortical perfusion. Methods The animal model was established with ligating renal artery to cause the renal cortical perfusion decrease of rabbits. Real-time harmonic gray scale imaging was performed to visualize the contrast enhancement of the renal cortex. After bolus injection of contrast agent SonoVue, dynamic image was observed and recorded during the first three minutes. According to the time-intensity curve (TIC), accelerating time (AT),Peak intensity (A), time to half of peak intensity (T), difference between peak and base (PBD), slope rate of the curve (β) and the product of A and β (A·β) were obtained before and after the renal artery operation. The t test and correlation analysis was used to examine the above parameters. Results Before the renal artery operation, renal cortex enhanced rapidly and obviously, the way of the enhancement was renal artery-cortex-pyramids. After ligation of renal artery, AT prolonged evidently (P<0.001), A decreased obviously (P<0.001), T obviously shortened (P<0.001), PBD decreased markedly (P<0.001), while the decline of βinduced (P<0.002) and A·βobvious dropped(P<0.001). AT, BPD and A·βcorrelated with stenosis level of renal artery. Compared with 31%－69% group, AT prolonged evidently (P<0.001). A decreased obviously (P<0.029), PBD decreased obviously (P<0.001), A·β was dropped markedly (P<0.02) in 70%-93% stenosis group. Conclusions Contrast agent combining with developed contrast specific imaging is able to detect changes of renal cortical microcirculation sensitively with the help of analysis of TIC.
