Synergetic antiplatelet effects of aqueous extracts of Fructus Crataegi and Rhizoma Alismatis in vitro were studied. The interaction of the two drugs was also observed. Results showed that the IC50 of Fructus Crataegi on platelet aggregation induced by ADP was 1.388g/100ml,whereas the IC50 of Rnizoma Alismatis was 7. 585g/100ml. In the presence of low concentrations of Fructus Crataegui (0.3~0.9g/100ml ),the an　tiplatelet activity of Rhizoma Alismatis was significantly increased,and the IC50 was only 1.755g/100ml with the presence of 0. 9g of Cralaegus pinnatifida per 100ml. These results suggested that the two drugs have a mutual synergetic effect on antiplatelet function

目的观察中药四磨汤对胆道手术后患者肠功能恢复的影响。方法133例行胆道术患者分为治疗组(90例)和对照组(43例),治疗组患者术前2h和术后每6h口服四磨汤30—40ml,对照组患者术后采用常规治疗,观察记录两组患者肛门排气时间。结果治疗组患者术后肛门排气时间较对照组显著提前(P<0.001)。结论术前、术后口服四磨汤可有效促进胆道手术患者肠功能恢复。

Objective To explore the effect of combined prescription medication on non-dipper hyperten sive patients.Methods 76 patients with non-dipper hypertensive patients were randomly divided into group A (n =38) and group B (n =38).Telmisartan tablets,hydrochlorothiazide tablets and levamlodipine tablets were given in two groups.Patients in group A take oral medicine at 8 pm,and patients in group B take oral medicine at 8 pm.The levels of plasma angiotensin Ⅱ,plasma endothelin-1 (ET-1),plasma renin,matrix metalloproteinase9 (MMP-9) and Chemerin protein were observed in both groups.Results After treatment,24 h SBP,dSBP and nSBP in group B were significantly lower than those in group A (P ＜ 0.05).The dipper value of group B was significantly higher than that of group A (P ＜ 0.05).The diversion rate of group B was significantly higher than that of group A (P ＜ 0.01).The levels of renin,angiotensin Ⅱ,ET-1,MMP-9 and Chemerin in group B were significantly lower than those in group A at 6 AM and 0:00 (P ＜ 0.05).The degree of change in group B at 0:00 was more significant than that in 6:00 AM (P ＜ 0.05).There was no significant difference in the incidence of adverse reactions between the two groups (P ＞ 0.05).Conclusion The efficacy of telmisartan,hydrochlorothiazide combined with levamlodipine in patients with non-dipper hypertensive patients performs better if patients take medicine at 8 pm other than at 8 pm.

Objective To investigate the expressiorn of microRNA-622(miR-622) and dual specificity tyrosine phosphorylation-regulated kinase 2 (DYRK2) in colon cancer tissues and cell lines and explore the effect of miR-622 on SW11l6 cells migration and invasion.Methods Eighty-two colon cancer tissues and paired para-tumor tissue specimens were collected.C.olon cancer cell line SW1116,SW480 and normal human colon epithelial cell line NCM460 were cultured.MiR-622 was detected by using Real time PCR,DYRK2 expression was measured by using immunohistochemistry,Real time PCR anid Western blot in tissue level and cell level,respectively.The relation of miR-622 and DYRK2 was analyzed by Pearson correlation analysis.miR-622 mimics transfection was conducted to up-regulate miR-622,while negative control,NC group were transfected with control sequence.Expression of DYRK2 was evaluated by using Real time PCR and Western blot,while Transwell chamber assays were used to assess the migration ability changes.Results Real time PCR and Western blot results showed that miR-622 mRNA was highly expressed in colorectal cancer tissue and colon cancer cell SW1116,whereas DYRK2 mRNA and protein were lowly expressed when compared with paracancerous tissue and normal colonic epithelial cell line NCM460.An obvious negative correlation was showed between miR-622 and DYRK2(r=0.916,P＜0.01).Compared to NC group,DYRK2 mRNA and protein expression were down-regulated after transfection of miR-622 mimics,which was observerd through Real time PCR and Western blot(P＜0.01).Correspondingly,compared to NC group,the migration ability of SW116 was remarkably enhanced after transfection of miR-622 mimics(P＜0.01).Conclusion The expression of miR-622 is high and DYRK2 is low in colon cancer.Up-regulation of miR-622 could negatively regulate DYRK2 expression and promote SW1116 cells migration.
