Reversed phase high performance liquid chromatography with diode array detector was employed for simultaneous determination of five main index components and specific chromatograms analysis in Xiaochaihu granules with a linear gradient elution of acetonitrile-water (containing 0.1% phosphoric acid) as mobile phase. The results showed that five main index components (baicalin, baicalein, wogonoside, wogonin, enoxolone) were separated well under the analytical condition. The linear ranges of five components were 0.518 - 16.576, 0.069 - 2.197, 0.167 - 5.333, 0.009 - 0.297 and 0.006 - 0.270 mg x g(-1), respectively. The correlation coefficients were 0.999 9, and the average recoveries ranged from 95% to 105%. Twelve common peaks were selected as the specific chromatograms of Xiaochaihu granules with baicalin as the reference peak. There were good similarities between the reference and the ten batches of samples. The similarity coefficients were no less than 0.9. The analytical method established is highly sensitive with strong specificity and it can be used efficiently in the quality control of Xiaochaihu granules.

OBJECTIVETo investigate the effect of astragaloside (Astr), one of the active components of the Chinese medical herb Astragulus membranaceus, on cardiac fibrosis in chronic myocarditis and its relevant mechanisms.

METHODSEighty mice were randomized into 3 groups, the control group (n=20), the model group (n=30) and the Astr group (n=30). Mice in the model group and the Astr group were monthly intraperitoneally inoculated with CVB3, but to the control group equal amount of culture fluid was given instead. Mice in the control and the model group were fed with drinking water while those in the Astr group with drinking water containing Astr-sodium carboxymethycellulose at a concentration of 300 mg/L. All the survived mice were sacrificed 3 months later. Heart tissue of mice was stained by picrosirius red for calculating collagen volume fraction (CVF) with an automatic image analysis system. Expressions of transforming growth factor beta1 (TGF-beta1), platelet derived growth factor (PDGF), matrix metalloproteinase 1 (MMP-1), tissue inhibitor of metalloproteinase 1 (TIMP-1), MMP-13 and MMP-14 in heart tissue were detected by Western blot analysis.

RESULTSAs compared with the model group, in the Astr group, the mortality and CVF were significantly lower (53.3% vs. 23.3%, chi2 = 4.23, P < 0.05), and (17.4 +/- 1.2% vs. 8.6 +/- 0.9%, chi2 = 5.38, P < 0.05), respectively. As compared with the control group, Western blot analysis showed that expression of TGF-beta1 was decreased, MMP-1 and TIMP-1 were down-regulated, while expressions of MMP-13 and MMP-14 were up-regulated after Astr treatment.

CONCLUSIONAstr could lower the mortality and alleviate the myocardial fibrosis of mice with chronic myocarditis. Its antifibrotic effect might be realized by way of inhibiting TGF-beta1 expression and up-regulating the expressions of MMP-13 and MMP-14 in the heart tissues.

Objective: To observe the effects of moxibustion therapy at Shenshu (BL 23) and Zusanli (ST 36) of rats with induced rheumatoid arthritis (RA) on the serumal intercellular cell adhesion molecule-1 (ICMA-1) and the pathological tissue, to discuss the mechanism of the warming and activating effect of moxibustion. Methods: After establishing the RA rats model, the induced rats were treated with moxibustion therapy on the acupoint Shenshu (BL 23) and Zusanli (ST 36), followed by analyzing the pathological section of the ankle of the hind limb and testing the ICAM-1 content with ELISA. Results: The plantar circumferences of the induced rat increased significantly compared with the rats in the control group (P<0.01), accompanying with the increase of the synovial layer, the erosion of phlogocytes to chondrocytes and the specific increase of ICAM-1 content. After the moxibustion therapy, the plantar circumferences decreased significantly (P<0.01) while the synovial layer tended to reduce. In addition, there was no pathological damage of the articular cartilage and the ICAM content decreased with significant deviation (P<0.01), compared to the model group. Conclusion: It was concluded that moxibustion therapy could inhibit the arthrosynovitis and hyperplasia, ameliorate the erosion of phlogocyte to cartilage, prevent articular periosteal lesions and delay the pathological course. The warming and activating effect of moxibustion therapy may involve the inhibition of the formation of ICAM-1 and pannus.

Objective To investigate the correlation between micro?bleeds and hemorrhagic transformation( HT ) after ischemic stroke. Methods One hundred and forty?five cases patients with acute ischemic stroke who were admitted to Luhe Hospital of Beijing Affiliated to Capital Medical University from 2009 to 2014 were retrospective analyzed. The MBs T2??weighted gradient?echo MRI was performed within 48 hours after admission to examine if there was a micro?bleeds,and the incidence of HT was assessed using follow?up brain MRI or CT in 2 weeks after admission. There were 125 patients with stroke were in without HT group and 20 patients were in HT group. Results There were no significant differences in terms of MBs ( P=0. 170 ) , gender( P=0. 671 ) , age ( P=0. 528 ) , hypertension ( P=0. 597 ) , diabetes ( P=0. 571 ) , hyperlipidaemia ( P=0. 772),smoking(P=0. 672),history of stroke(P=0. 469),coagulation function(P=0. 527),antiplatelet(P=0. 642),anticoagulation(P=0. 611) in HT group and without HT group. Atrial fibrillation((45%(9/20) vs. 22%( 28/125 ) , P = 0. 034 ) , NIHSS score ( 10. 9 ± 0. 5 ) points vs. ( 7. 8 ± 1. 2 ) points, P<0. 001 ) , thrombolysis(20% (4/20) vs.5% (6/125),P = 0.015) have significant differences in two groups.In multivariate logistic regression analysis,atrial fibrillation( OR=2. 421,95%CI 1. 823-3. 256,P=0. 012) ,NIHSS score( OR=9. 303, 95%CI 3. 094-27. 970, P<0. 001 ) were independent predictors for HT after ischemic stroke. Conclusion There is no relationship between MBs and HT after ischemic stroke. Atrial fibrillation,the severe of stroke are independent predictors for HT after ischemic stroke.

Objective To study the pharmacokinetic features of ferulaic acid, senkyunolide A and ligustilide in Buyang Huanwu associated prescriptions (Buyang HuanwuDecoction andNaojianTablets).MethodsHPLC-DAD was applied for simultaneous determination plasma concentration of three ingredients with jugular venous cannula rats after intragastric administration ofBuyang Huanwu associated prescriptions.
