OBJECTIVE:To evaluate clinical efficacy through comparing the change of CT image in infrapatellar fat pad before and after Xiaoding ointment in the treatment of acute patellar bursitis of knee joint. METHODS:73 patients with acute patellar bur-sitis were randomly divided into observation group(39 cases)and control group(34 cases). Observation group was given Xiaoding ointment for local application,qd,7 d as a courses,3 courses in total;control group was given triamcinolone acetonide 30 mg af-ter the extraction of articular cavity effusion,once a week,totally for 3 times. All patients of two groups underwent knee CT exami-nation for observation of the infrapatellar fat pad and articular cavity effusion volume change before and after treatment. Clinical ef-ficacies were compared between 2 groups. RESULTS:CT image alterations of treatment group showed that infrapatellar fat pad den-sity were decreased,anteroposterior diameter,vertical diameter,internal to external diameter were significantly reduced. The total effective rate of treatment group was 92.31%,which was better than that of control group(88.24%),with statistical significance (P<0.05). CONCLUSIONS:Xiaoding ointment demonstrate markedly curative effects in the treatment of acute patellar bursitis, and CT image is an effective method for diagnosis of infrapatellar fat pad.

Objective To explore the effects of aqueous extracts of Codonopsis Radix onD-galactose induced aging model mice; To discuss the anti-aging molecular mechanism of Codonopsis Radix.Methods Subcutaneous injection ofD-galactose solution was used to establish aging models. 100 Kunming mice were divided into normal control group, model group and low-, medium-, high-dose of Codonopsis Radix interventional groups randomly, 20 mice in each group. Low-, medium-, high-dose of Codonopsis Radix interventional groups were given relevant dosage for gavage, while normal control group and model group were given the same volume of NS by gavage for 42 d. After treatment for 42 days, the BUN and CREA in mouse serum were examined; the AffymetrixmiRNA 4.0 microarray was employed to identify the differentially expressed microRNA (miRNA) related with these processes; the bioinformatic tools were also used to further analyze the cluster of miRNA microarrys and the pathways which the target genes of miRNA were involved in.Results Compared with normal control group, the levels of BUN and CREA in mouse serum increased in model group (P<0.05); compared with model group, the levels of BUN and CREA in Low-, medium-, high-dose of Codonopsis Radix interventional groups decreased, in which high-dose of Codonopsis Radix could most significantly inhibit the level of BUN (P<0.05); the cluster analysis showed the miRNA expression profilings of high dose of Codonopsis Radix interventional group and normal control group were brought together, while the profiling of model group was clearly divided with the other groups. In model group vers normal control group, 36 differentiated expressed miRNA showed, which predicated in 10 main biological functions. In high-dose of Codonopsis Radix interventional group vers model group, 34 differentiated expressed miRNAs in high-dose of Codonopsis Radix interventional group showed, and the analytical results of biological functions of target genes were the same as those of model group vers normal control group.Conclusion In the anti-aging process, Codonopsis Radix can not only influence the miRNA expression profiling, but also influence its functional environment.

Objective:To establish an UHPLC-MS/MS method to determine the contents of baicalin,scutellarin,wogonin,caffeic acid,ephedrine,belamcandin,irisflorentin and baicalein in Shegan mixtures. Methods:The chromatographic separation was performed on a ZORBAX SB-C18 column(2. 1 mm × 50 mm,1. 8 μm)with the mobile phase consisting of acetonitrile and water(0. 1% formic acid),the flow rate was 0.3 ml·min-1,and the column temperature was 35℃. Electrospray ionization source(ESI)was used with multiple reaction monitoring( MRM)combined with positive and negative scanning switch. üegative ion mode detection was used for caf-feic acid,belamcandin and scutellarin ,while positive ion mode detection was used for baicalin,wogonin,irisflorentin,baicalein and e-phedrine. Results:The quantification limit of baicalin,scutellarin,wogonin,caffeic acid,ephedrine,belamcandin,irisflorentin and ba-icalein was 1. 44 × 10-4 ,4. 20 × 10-3 ,2. 95 × 10-4 ,7. 80,4. 90 × 10-3 ,4. 6 × 10-2 ,3. 18 × 10-4 ng·ml-1 and 4. 85 ng·ml-1 . The detection limit was 4.32 ×10-5,1.3 ×10-3,8.84 ×10-5,0.77,2.90 ×10-4,3.33 ×10-4,9.5 ×10-5 ng·ml-1 and 1.46 ng· ml-1 ,respectively. The correlation coefficients( R2 )were all higher than 0. 992 3 within the linear ranges. Both intra- and inter-day RSD were less than 5%. The average recoveries of the eight components were within the range of 80%-120%. Conclusion:The method is simple,rapid,sensitive and accurate. It can be used to determine the contents of baicalin,scutellarin,wogonin,caffeic acid,ephed-rine,belamcandin,irisflorentin and baicalein in Shegan mixtures for the quality control.

Objective:To analyze the chemical constituents in Radix astragali by high-performance-liquid chromatography-time of flight mass spectrometry(HPLC-TOF/MS). Methods:An Agilent poroshell 120 SB-C18 column(100 mm × 3 mm,2. 7 μm)was adopt-ed. The mobile phase was composed of acetonitrile-0. 1% formic acid with nonlinear gradient elution. The flow rate was 0. 4 ml· min-1 . The UV detection wavelength was set at 254nm, the column temperature was 25℃ and the injection volume was 10μl. Electron spray ionization and positive mode was adopted, the flow and temperature of the carrier gas( N2 ) was 10 L·min-1 and 350℃, respec-tively. The capillary voltage was 4 kV, the bombardment voltage was 165 V, the spectra were recorded within the range of m/z 100~1 100. Results:A total of 24 chemical constituents were identified from Radix astragali by HPLC-TOF/MS simultaneously. Conclu-sion:An efficient and fast HPLC-TOF/MS approach has been established for studying the chemical constituents in Radix astragali, which lays the foundation for the study on pharmacodynamic material basis and quality control of Radix astragali.

Objective: To determine the pharmacokinetics of ephedrine hydrochloride in rats after intragastric administration of Shegan mixtures. Methods:Shegan mixtures (1. 0 ml/100 g) were administered to each rat by gavage. Blood samples were collected after the administration. Plasma concentration of ephedrine hydrochloride was determined by LC-MS/MS. The pharmacokinetic parame-ters of ephedrine hydrochloride were obtained using the pharmacokinetic software. Urine and fecal samples were collected in 24 hours after the administration using metabolic cage to determine the recovery of ephedrine hydrochloride. Results: The pharmacokinetic pa-rameters of ephedrine hydrochloride were as follows:Tmax of (1. 30 ± 0. 23)h,T1/2 of (21. 17 ± 1. 35)h, Cmax of (278. 86 ± 46. 41)ng ·ml-1,AUC0~∞ of (1221.98 ±412.64)ng·ml-1 and Vc/F of (1.70 ±0.15)L. Totally 85.66% ephedrine hydrochloride could be recovered from urine in 24 hours after the administration;however, it was not detected in the fecal samples. Conclusion: Most of e-phedrine hydrochloride is excreted through kidney in 24h,therefore, Shegan mixtures can't cause the accumulation of ephedrine hydro-chloride in rats.
