Objective To compare the efficacy of pantoprazoh based short-term quadruple regimens in the treatment of Helicobacter pylori (H. Pylori) infection for 4 days,5 days or 7days. Methods 166 patients with H. Pylori associated severe gastritis were randomly divided into pantoprozole quadruple regimens of 4-day group (n =61) ,5-day group (n = 54) or 7-day group (n = 51). The regimen was pantoprazole 40 mg,bismuth potassium citrate 220 mg,elarithromycin 250 mg and amoxicillin 1 g twice daily. The patients received pantoprazole for 1 week, bismuth potassium citrate for 2 weeks,clarithromycin and amoxicillin for 4 days,5 days or 7 days respectively. The H. Pylori eradication and symptomatic relief was determinded by 13C-UBT at least 4 weeks after the therapy. Results The H. Pylori eradication rates of 4-day,5-day or 7-day panteprazole quadruple regimens were 73.8% (45/61) ,75.9% (41/54) and 80.4% (41/51) respectively. The pain relief rates were 82.4% (42/51) ,85.1% (40/47) and 88.9% (40/45) in 4-day,5-day and 7 day group. Conclusion The 4-day and 5- day pantoprazoh based quadrual therapy is a short- term, effective, safe and lower therapeutic- cost regimen for H. Pylori eradication.

Objective To investigate the regulation of metabolize characteristic of some antibiotics in ACST in human bile, and provide the theoretic basis for physician selecting antibiotic rationally when biliary tract has been infected. Methods Samples of ACST in human bile were obtained by ERCP + ENBD, contents of Cefradine, Cefoperazone, Ceftriaxone, Ciprofloxacin and Lomefloxacin in human bile were simultaneously measured by HPLC method. Results After antibiotics were given through iv 0. 25 ～ 1. 5 hour, an increase was observed in contents of all antibiotics in bile, and the changes of Ceftriaxone and Ciprofloxa-cin were the most significant ( P <0.01). Ceftriaxone and Ciprofloxacin had a higher Cmax than other antibiotics, and Cefoperazone had a longer tl/2. Conclusion As maintaining a little time to tmax , a higher Cmax and a longer tl/2 in the bile by iv, Cefradine and Ciprofloxacin are recommended in the patient with ACST.

Eight 1,6-O,O-diacetylbritannilactone (OABL) derivatives (compounds 1-8) were synthesized by esterification or reduction of 1-O-diacetylbritannilactone (ABL) isolated from Inula japonica.All derivatives were evaluated for their anti-inflammation activities through the determination of inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-induced macrophages.As results,compounds 5-8 (IC50 ＜ 2 μmol/L) exhibited more potent inhibition of NO production activities than the lead compound OABL.

Objective To evaluate the efficacy of 10-day compound allantoin containing quadruple regimen in the treatment of chronic gastritis with Helicobacter pylori (H.pylori) infection,and to compare with the bismuth-containing quadruple therapy.Methods Altogether 173 patients with H.pylori positive chronic gastritis confirmed by gastric endoscope were divided into 10-day compound allantoin containing quadruple regimen group (n =43),24-day compound allantoin containing quadruple regimen group (n =46),10-day bismuth-containing quadruple regimen group (n =42) and 24-day bismuth-containing quadruple regimen group (n =42).After the treatment,the eradication rate of H.pylori,the rate of gastrointestinal symptoms (epigastric pain,bloating and belching) relief and the adverse effects of each group were observed.Intention-to-treat (ITT),per-protocol (PP) statistical analysis and chi-square analysis were performed for statistical analysis.Results H.pylori eradication rates of 10-day compound allantoin containing quadruple regimen group,24-day compound allantoin containing quadruple regimen group,10-day bismuth-containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group analyzed by ITT were 90.7％ (39/43),91.3％ (42/46),90.5％ (38/42) and 88.1％ (37/42),respectively; while analyzed by PP were 90.7％ (39/43),93.3％ (42/45),90.5％ (38/42) and 90.2％ (37/41),respectively.And there were no statistical differences between groups (all P＞0.05).Ten days after the treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 81.1％ (30/37) and 78.8％ (26/33),respectively,the rates of bloating relief were 82.4％ (28/34) and 71.0％ (22/31),respectively,and the rates of belching relief were 76.9％ (20/26) and 75.0％ (21/28),respectively.There were no statistical differences between the two groups (all P＞ 0.05).However after 24-day treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 91.9 ％ (34/37) and 87.9％ (29/33),respectively,the rates of bloating relief were 94.1％ (32/34) and 87.1％ (27/31),respectively,and the rates of belching relief were 96.2％ (25/26) and 85.7％ (24/28),respectively.There were no statistical differences between the two groups (all P＞0.05).And the rates of epigastric pain and bloating relief increased after 24-day treatment compared with those of 10-day treatment,however the differences were not statistically significant between the two groups (all P＞ 0.05).In 24-day compound allantoin containing quadruple regimen group,the rate of belching relief was higher after 24-day treatment compared with that of 10-day treatment,and the difference was statistically significant (x2=4.127,P=0.042).No severe adverse effects were observed in each group,and there were no adverse effects such as oral metal odor,tongue black and melena in compound allantoin containing quadruple therapy.Conclusions Ten-day compound allantoin containing quadruple therapy as first-line approach in the treatment of chronic gastritis with H.pylori infection can get better H.pylori eradication and the efficacy is similar to bismuth quadruple therapy.Meanwhile the symptom relief rate is high and no obvious adverse effects were found.

Tubulointerstitial fibrosis (TIF) is a common pathological feature of end-stage kidney disease. Previous studies showed that upregulation of TGFbeta1 notably contributed to the chronic renal injury and irbesartan halted the development of TIF in rats with 5/6 renal mass reduction. This study was to investigate the effects of irbesartan on chronic TIF and the mechanism involved TGFbeta1 in the rodent model of chronic renal failure involving 5/6 nephrectomy. The results showed that irbesartan significantly attenuated the rise in blood pressure and tubulointerstitial injury observed in this model. Masson staining of the renal tissue revealed that there appeared severe renal tubule atrophy and fibrosis in operation group, but the lesion was attenuated mostly in irbesartan-treated group. Immunohistochemistry showed that irbesartan treatment apparently decreased the protein expression of TGFbeta1 which was up-regulated in operation groups. Western blot showed that irbesartan treatment down-regulated the expression of TGFbeta1, phosphorylated smad2 (p-smad2), AT1R and phosphorylated p38 (p-p38) MAPK, but significantly up-regulated the protein expression of smad6 as compared with operation group. These findings suggest that irbesartan attenuates hypertension and reduces the development of TIF in rats with 5/6 renal mass reduction via changes in the expression of these proteins at least including smad6, TGF-beta1, p-smad2, AT1 and p-p38 MAPK.
