Objective: To study the scutellaria and coptis in different proportions, the main active ingredient of baicalin, berberine dissolution rate changes and to explore the effect of traditional drug pair of scutellaria and coptis on the dissolution rate of active ingredient. Methods: Based on the clinic common used prescriptions of scutellaria with coptis, ratio of 1:0,1:1,1:2,1:3,2:1,2:3,3:1,3:2,0:1 was selected, after the water boiling reflux extraction, refining separation, various products were obtained for the test, under the optimized conditions of RP-HPLC analysis to compare chromatographic fingerprints and to examine the main component baicalin, berberine in aspects of relative peak area ratio of changes and compatibility relations. Results: Compatibility of Scutellaria baicalensis and Coptis at different proportions can influence the dissolution rate of baicalin, Berberine Hydrochloride. There was a non-linear relationship of dissolution rate of baicalin and Scutellaria baicalensis. The best ratio of scutellaria ratio was 3:1, the best compatibility ratio of coptis was 1:3. Conclusion: Different compatibility proportions of scutellaria and coptis will result in different dissolution rate of baicalin and berberine.

Objective To investigate the effects of Panax notoginseng saponins (PNS) on the cerebral water content and thrombin in the rats with intracerebral hemorrhage (ICH), and explore its mechnism for treating ICH. Methods SD male rats were randomly divided into blank group, sham operation group, model group and treatment group, and time points of 6, 24, 48, 72 h and 7 d were observed. ICH rat model was induced by collagenase and heparin in saline solution injected into caudate nucleus. The treatment group was injected PNS intraperitoneally once a day, and the cerebral water content was assessed by dry-wet weight method. Both content of fibrinogen (FIB) and thrombin clotting time (TT) in 48 h were measured. Results The cerebral water content of model group increased at every time point compared with blank group and sham operation group (P<0.05). The cerebral water content of treatment group was significantly decreased at every time point except for 6 h compared with model group (P<0.05). FIB of treatment group decreased compared with model group (P<0.05), while TT of treatment group was not significantly decreased (P>0.05). Conclusion PNS may play a role in treating ICH by decreasing cerebral water content, FIB and TT of ICH rats.

AIM To study the effects of Lotusine(Lot), a pure alkaloid extracted from the green seed embryo of Nelumbo nucifera Gaertn, on the action potentials(APs) in myocardium and slow inward current(Isi) in cardiac Purkinje fibers(PF). METHODS standard microelectrode and two microelectrodes voltage clamp techniques were used. RESULTS Lot 1～100 ?mol?L -1 could concentration dependently prolonged APD 20 and APD 90 of fast AP and increase the contractile force(Fc) in guinea pig papillary muscles. In papillary muscles pretreated with reserpine, similar results were also observed but the effect of Lot was weaker than those pretreated without reserpine. In guinea pig left atria, Lot 30 ?mol?L -1 could partly antigoniste the shortening APD effect of acetylcholine. Lot 3～100 ?mol?L -1 could enhance the action potential amplitude(APA)and maximal velocity of phase 0 depolarization ( V max ) of slow AP of papillary muscles induced by high K + (24 mmol?L -1 )and isolated sinoatral node(SAN) pacemaker cells of rabbits with dose dependent manner,But not obvousely short the sinus cycle length of SAN. Moreover, Lot increased the Isi of in canin cardiac PF with with time dependent and dose dependent manner. CONCLUSION The results suggest that Lot has effect of prolongation of APD and increase of Ca 2+ influx and these are very important in contribution to its positive inotropic effect, which may be related to inhibition of phosphodiesterase Ⅲ.

Background and purpose:Cyclooxygenase-2 (COX-2) participates in angiogenesis and lymph node metastasis of lung cancer. COX-2 inhibitors could inhibit invasion and metastasis of lung cancer. This study aimed to investigate the inhibition of invasion and metastasis by COX-2 inhibitor imrecoxib in xenograft tumor of lung adenocar-cinoma A549 cell in nude mice and to explore its possible mechanisms, in addition, to observe the efficacy of imrecoxib combined with lobaplatin.Methods:Thirty male BALB/c nude mice were injected subcutaneously with A549 cells into the right axillary region to establish xenograft models. Twenty-nine successfully modeled mice were randomly divided into four groups: control group (n=7), imrecoxib group (n=8), lobaplatin group (n=7), imrecoxib combined with lobaplatin group (n=7). The control group was treated with the same amount of sterile distilled water and injected with the same amount of 0.9% sodium chloride solution via caudal vein. The treatment group was treated with imrecoxib tablets 40 mg/kg per day through gavage and injected with lobaplatin 7.5 mg/kg per week via caudal vein respectively. The diet, physical activity and other normal conditions of nude mice were observed everyday. After 6 weeks, 29 mice were sacrificed and transplanted tumor tissues were cut off. The expression of PTEN, cortactin protein and mRNA were detected by immunohistochemistry and real-time PCR. The data were analyzed with one-way anova and non-parametric test.Results:In the last week, the diet and physical activity of all nude mice were less than before, and they became thinner, which were more obvious among the mice in lobaplatin group and imrecoxib combined with lobaplatin group. Compared with the control group, the expression of PTEN protein and mRNA were significantly increased in imrecoxib group and imrecoxib combined with lobaplatin group (P<0.001, respectively). Compared with the control group, the expression of cortactin protein and mRNA were significantly decreased in imrecoxib group and imrecoxib combined with lobaplatin group (P<0.001, respectively). PTEN and cortactin protein, PTEN and cortactin mRNA had significantly negative correlation (r=-0.660, -0.983,P<0.001, respectively). Conclusion:Imrecoxib can inhibit non-small cell lung cancer invasion and metastasis which may be involved in upregu-lating PTEN protein and reducing cortactin protein. Imrecoxib could enhance the effect of lobaplatin chemotherapy.

Objective To investigate the short axis systolic function of children with single-left ventricle(LV),and to appraise the clinical value of velocity vector imaging(VVI) on assessing it.Methods The study group consisted of 14 patients with single-LV.The control group consisited of 14 age-matched normal children.VVI was used to analyse the circumferential and radial strain and strain rate of regional single-LV at the level of papillary muscle.Results Compared with values in control group,single-LV circumferential strain values were significantly lower in anterior septum,posterior septum,anterior wall,lateral wall and inferior wall(all P ＜0.05).Single-LV circumferential strain rate values were significantly lower in anterior septum,posterior septum,anterior wall,lateral wall and posterior wall compared with controls(all P ＜0.05). In control group,circumferential strain and strain rate were higher in inferior septum and anterior septum compared with other segments( P ＜0.05).Single-LV radial strain values were significantly lower in all segments compared with values in control (P ＜ 0.05).In control group,radial strain and strain rate of papillary muscle level showed no significantly difference( P ＞0.05).Conclusions Circumferential and radial systolic ventricular function are impaired in children with single-LV.VVI can beused as a quantitative tool in evaluating the short axis systolic function of single-LV.
