ABSTRACT
Objective To evaluate the efficacy and safety of modified sequential therapy versus different quadruple therapy for the helicobacter pylori (H .pylori) eradication .Methods A total of 240 H .pylori infected patients with non atrophic gastritis accompanies erosion and peptic ulcer diagnosed by gastroscopy ,were evenly divided into sequential therapy group (A group) ,con-comitant therapy group(B group) ,7 days bismuth-containing quadruple therapy group(C group) and 10 days bismuth-containing quadruple therapy group(D group) .A group :rabeprazole 10 mg ,amoxicillin 1 000 mg were taken twice daily for 5 days firstly ,then rabeprazole 10 mg ,clarithromycin 500 mg ,furazolidone 100 mg were taken twice daily for 5 days .B group :rabeprazole 10 mg , amoxicillin 1 000 mg ,clarithromycin 500 mg ,furazolidone 100 mg were taken twice daily for 7 days .C group and D group :rabe-prazole 10 mg ,bismuth 220 mg ,amoxicillin 1 000 mg ,clarithromycin 500mg were taken twice daily for 7 and 10 days respectively . H .pylori status was re-assessed with 14C-urea breath test after 4-weeks therapy .Results Among them ,224 cases completed the study .According to the analysis of intention-to-treat (ITT ) ,the H .pylori eradication rates of A ,B ,C ,D group were 88 .33% , 83 .33% ,73 .33% ,81 .67% respectively ,and according to per-protocol (PP )analysis which were 92 .98% ,90 .90% ,78 .57% , 87 .50% .The difference between A and C group was statistically significant (χ2 = 4 .36 ,4 .83 ,P= 0 .037 ,0 .028) .Conclusion Fura-zolidone-containing sequential therapy provide provide high H .pylori eradication rates ,which could be the first-line treatment option .
ABSTRACT
Objective To explore the anti-inflammatory and analgesic effects of Shuangwu numbness-relief decoction. Methods The anti-inflammatory effect was assessed by xylene-induced mouse auricular swelling and peritoneal capillary permeability;and the analgesic effect was assessed by hot plate method and acetic acid-induced twisting method. Results Shuangwu numbness-relief decoction at moderate or high dose had a significant inhibitory effect on mouse auricular swelling, with a significant difference as compared with the control group (P<0.01);the decoction at low , moderate , or high dose group played a marked inhibitory role in the increase in mouse peritoneal capillary permeability (P<0.01). Shuangwu numbness-relief decoction at moderate or high dose effectively reduced the writhing frequency in mice (P < 0.01). The decoction at high dose increased the pain threshold in mice one hour after intragastric administration (P < 0.05), and the decoction at moderate or high dose increased the pain threshold two hours after administration (P < 0.05). Conclusions Shuangwu numbness-relief decoction has an obvious anti-inflammatory and analgesic effect.
ABSTRACT
Objective To observe the anti-tumor effects of Agrimonia Pilosa Ledeb(APL) ,a Chinese herbal medicine ,on hepato-cellular carcinoma cells in vitro and investigate the underlined mechanisms preliminarily .Methods APL water extracts were pre-pared .SMMC-7721 cells were cultured with the medium containing different concentrations of APL water extracts ,and at different time points ,cell viabilities were measured by the MTT assay and inhibitory rates (IR) were calculated ;cell morphologic changes were observed under a light microscope ;apoptotic ratios were measured by flow cytometry ;and the expressions of Bcl-2 and P53 proteins were examined by immunocytochemistry .Results After the cells were cultured with the medium containing APL water ex-tracts for 24 h ,48 h and 72 h ,no obvious effects were found on the cell proliferation in 5 mg/mL group and 10 mg/mL group ,but IR were 0 .5% ,23 .9% and 27 .5% in 20 mg/mL group and 23 .3% ,51 .7% and 71 .6% in the 40 mg/mL group ,respectively .In the groups with effects on the cells proliferation ,morphological characteristics of apoptosis were obvious ,and the cell apoptotic ratios were 19 .5% and 23 .0% in 20 mg/mL group and 33 .4% and 42 .7% in 40 mg/mL group at 48 h and 72 h .The expressions of Bcl-2 protein were 71 .9% and 58 .5% in 20 mg/mL group and 47 .9% and 26 .5% in 40 mg/mL group at 48 h and 72 h ,and the ex-pressions of P53 protein were 22 .9% and 50 .6% in 20 mg/mL group and 48 .7% and 83 .7% in 40 mg/mL group at 48 h and 72 h . Conclusion The water extracts of APL are able to inhibit proliferation and induce apoptosis of SMMC-7721 cells dose-time depend-ently in vitro ,which might be associated with the expression changes of Bcl-2 and P53 protein .
