OBJECTIVETo prepare the gel of Chinese medicine catechu,study its release mechanism in vitro and observe the anti-inflammatory activity in rats.

METHODUsing the amount of catechin and epicatechin in dry extract as major evaluation factors, orthogonal experiment was carried out to investigate four influential factors of the ethanol concentration, ratio of raw material to solvent, ultrasonic time and extraction temperature. The catechu gel was prepared by using carbomer-940 as the gel base, and triethanomine as neutralizer. The experiments on drug-releasing profiles in vitro and the phamacodynamics studies on the anti-inflammatory in rats were carried out, respectively.

RESULTThe optimum condition of extraction from catechu was as follows, the concentration of ethanol, ratio of raw material to solvent, ultrasonic time, and extraction temperature were 50% , 1: 12, 35 min and 60 degrees C, respectively. The formulation of catechu gel was carbomer-9 400.5 g, glycerol 5.0 g, the extracts of catechu 50.0 mL, and triethanomine 0.5 mL The gel was semitransparent and stable. The drugs released quickly. The catechu gel reduced the paw edema considerably in dose-dependent manner compared to carrageenan-induced rat.

CONCLUSIONThe formulation of the catechu gel is reasonable, and it shows remarkable anti-inflammatory activity. It is worth doing further research.

Jervine, a novel steroidal alkaloid from Veratrum nigrum L., exhibits both antitumor effect and potential toxicity. The aim of study was to characterize the pharmacokinetic behaviors and enterohepatic circu-lation of jervine in rats. A rapid and simple ultra-high performance liquid chromatography-tandem mass spectrometric method was developed and validated for quantification of jervine and alpinetin (internal standard) in rat plasma. After extraction from rat plasma by a simple protein-precipitation method, the analyte was separated on a C18 column (2.1 mm × 50 mm, 1.7μm) using water with 0.1％formic acid and acetonitrile as the mobile phase delivered at a flow rate of 0.4 mL/min. Jervine and alpinetin were determined in the positive mode with multiple reaction monitoring (MRM) of the ion transitions at m/z 426.3→108.8 and m/z 271.0→166.9, respectively. Molecular docking method was used to investigate the binding of jervine to p-glycoprotein and dehydroepiandrosterone sulfotransferase. The method was well validated within acceptance limits including specificity, matrix effect, recovery, precision, accuracy, and stability, and was successfully applied to the pharmacokinetic study of jervine after oral and intravenous administration to rats. Jervine presented a small volume of distribution, fast absorption, high oral bioavailability, and enterohepatic circulation. The enterohepatic circulation was first observed in veratrum alkaloids, and was further investigated by molecular docking studies, which was related to the binding of jervine to p-glycoprotein and dehydroepiandrosterone sulfotransferase. The pharmacokinetic properties and enterohepatic circulation of jervine in rats provided a significant basis for the drug-drug interaction and toxicity study in the future.

OBJECTIVETo prepare the poly(lactic-co-glycolic acid) (PLGA) microspheres and composite alginate-chitosan-PLGA microspheres containing superoxide dismutase (SOD) and to evaluate their SOD activities.

METHODSThe SOD-PLGA microspheres were prepared by W/O/W emulsification method, and the composite microspheres were prepared by two steps:alginate-chitosan microcapsules were first prepared by a modified emulsification and ion crosslinking method, and then they were further dispersed in PLGA to form the composite microspheres. The SOD concentration was determined by Coomassie method, its activity was measured by xanthine oxidase system.

RESULTSThe SOD activity was less sensitive to temperature and sensitive to pH, organic solvents, ultrasound and vigorous stir without iced bath. The entrapment efficiencies of SOD in PLGA (50:50) microspheres, PLGA (70:30) microspheres, alginate-chitosan microcapsules, the composite PLGA (50:50) microspheres and the composite PLGA (70:30) microspheres were 36.42%±1.81%, 66.18%±0.05%, 91.08%±1.28%, 87.30%±3.89% and 83.19%±3.48%, respectively. In vitro release tests demonstrated that the SOD activities in 50:50 composite microspheres were higher than that in the PLGA ones at 1 h, 8 h and 1 w.

CONCLUSIONThe composite alginate-chitosan-PLGA microspheres for SOD sustained release can significantly improve the protein entrapment efficiency and maintain its protein activity.

Objective To compare the effect,relapse rate and outcomes between mycophenolate mofetil(MMF)and pulse intravenous cyclophosphamide(CTX)in the induction therapy of pauci-immune crescentic glomerulonephritis(PICGN)in Chinese.Methods A total of 44 patients who had PICGN[16 male,28 female,age(46.8?13.7)y],of whom 25 patients were ANCA positive,were enrolled in this study.All patients had renal involvement with ≥50% crescent formation prior to the study and received either MMF treatment(MMF group,n=22)or intermittent CTX pulse therapy(CTX group,n=22).The patients in both groups also received methylprednisolone(MP)pulse therapy followed by oral prednisone.General conditions,clinicopathological findings,remission rate,relapse rate,and outcomes were compared.All the patients were followed up until June 2005,with an average follow-up of 8～60(Med 27)months in the MMF group,and 6～72(Med 29)months in the CTX group.Results No significant difference was found between MMF group and CTX group in general conditions,base parameters of clinical and pathological findings.The remission rate at the 12th month in MMF and CTX group was 90.9% and 72.7% respectively.The complete remission rate in MMF group(59.1%)was significantly higher than that of the CTX group(27.3%)(P

Objective To evaluate the robustness of body mass index (BMI) adapted tube current selection method for obtaining consistent image quality in MSCT coronary artery imaging Methods Initially one hundred patients in the control group ( C group) underwent cardiac scans using GE 64-row VCT with standard scan protocol (640 mA, 120 kV, 0.35 see, body bewtie, C2 filter). Noise measurement was obtained for each patient using the average of three consecutive slices in the ascending aorta with ROI of 10 mm×10 mm to establish the relationship between BMI, desired image noise (IN) and required mA. An excel table was established to predict the required mA to achieve a desired IN for each patient with different BMI. A second group of one hundred cardiac patients (L group) was scanned with BMI-aclapted mA from the table to evaluate the practicability of this method. BMI, IN, CT dose index(CTDI),effective dose (ED) were all recorded. Results For the control group of 100 patients, the mean values and standard deviations of image quality score (IQS), BMI, IN and ED were 3.71±0.54, 25.08±2.63, 24.56±5.03 and (17.63±1.68 ) mSv (with range of 15-22 msy). Regression analysis indicated linear relationship between BMI and image noise with fixed mA. Using the relationship between tube current and image noise and noise ratio between large bowtie and cardiac bowtie, the following equation for the required tube current Xma to achieve present image noise of Ins for patient with certain BMI value when using cardiac bowtie could be then obtained: Xma = Fma×( k1 x BMI + c1 )/Ina]2, where Fma = 640 mA, k1 = 1. 033, c1 = - 3.2, Ins = 27 in the study. (2) For the patients in L group, the mean values and standard deviations of IQS, BMI, and IN were 3.69±0.53, 25.07±2.91, and 26.61±3.44, respectively. The average tube current used was (469.95±113.45) mA, depending on patient's BMI values. The average effectively dose was(9.08±2.25) mSv. There was no statistically difference between the two groups in image quality( F= 0.068,P=0.794). Conclusions In 64-MSCT cardiac imaging, the use of BMI dependent tube current selection method, in conjunction with dose reduction techniques, can provide individualized scan protocol to obtain consistent image quality across patient population and to optimize dose delivery to patients.
