The effects of natural andgeochemical factors depending on heavy metal contamination in nuisance dust particles were evaluated. The nuisance dust particles were sampled using passive deposit gauge method for one year from April2010 to March2011 and the obtained samples were measured for the total contents and the contamination levels of Fe, Mn, Cu and As usinggeo-accumulation index （Igeo ）, enrichment factor （EF） and the integrated pollution index （IPI）. The results showed that, the contamination levels of Fe and Mn based on Igeo values, were uncontaminated （Igeo 〈 0）（variations of the Igeo index was from -3.11 to -1.751 for Fe, from -0.630 to -1.925 for Mn）, while the values of Cu and As were demonstrated to have moderate contamination based on Igeo values （variations of Igeo index was from -1.125 to 0.848 for Cu, and from -2.002 to 1.249 for As）. The analysis of EF also revealed minor to moderate enrichment for Mn （1.215-4.214）, minor to moderately severe enrichment for Cu （2.791-6.484）, and As （1.370-8.462）, respectively. The variation of the IPI index also showed low to moderate level of heavy metal pollution in nuisance dust particulates （0.511-1.829）. The analysis of the results also approved that the natural processes andgeochemical variables （the changing meteorological parameters） can significantly affect the availability of heavy metals in nuisance dust particles in Western Iran.

Omeprazole-based triple therapy with low-versus high-dose of clarithromycin plus amoxicillin for H pylori eradication in Iranian population

World Journal of Gastroenterology 2007年第6期13卷 930-933页

AIM： To investigate the efficacy and tolerability of H pylori eradication in an omeprazole-based triple therapy with high and low dose of clarithromycin and amoxicillin. METHODS： One hundred and sixty H pylori positive patients were randomly assigned to two groups based on the following 2 wk investigation; （1） group A or low-dose regimen received omeprazole 20 mg b.i.d, clarithromycin 250 mg b.i.d and amoxicillin 500 mg b.i.d; and （2） group B or high-dose regimen received omeprazole 20 mg b.i.d, clarithromycin 500 mg b.i.d and amoxicillin 1000 mg b.i.d. During the study Hpylori status was assessed by histology and rapid urease test prior and by 13C-urea breath test 6 wk after the therapy. Standard questionnaires were administered to determine the compliance to treatment and possible adverse events of therapy. Data were subject to x^2 to compare the eradication rates in the two groups. The significant level of 95% （P ≤ 0.05） was considered statistically different. RESULTS： We found that the per-protocol eradication rate was 88% （68/77） in group A, and 89% （67/75） in group B. The intension-to-treat eradication rate was 85% （68/80） in group A and 83.75% （67180） in group B. Overall adverse events were 26% in group A and 31% in group B. The adverse events were generally mild in nature and tolerated well in both groups with a compliance of 98% in group A vs 96% in group B. CONCLUSION： The omeprazole-based low dose regimen of darithromycin and amoxicillin for two weeks in Hpylori eradication is as effective as high dose regimen in Iranian population.

Objective:To determine the efficacy of tranexamic acid(TXA)in the management of acute upper gastrointestinal(GI)***:A total of 70 patients with acute upper GI bleeding were included in this double-blinded randomized controlled clinical trial from September 2018 to December *** were divided into the control group(received fluid therapy and intravenous infusion of pantoprazole,35 cases)and the TXA group(received intravenous TXA besides the treatment of control group,35 cases).Rebleeding,admission duration,and need for blood transfusion were compared between the two ***:Fifteen patients(42.9%)in the TXA group and 10 patients(28.6%)in the control group stayed in hospital for more than 3 days during their admission(P=0.21).Rebleeding occurred in 8 patients(22.9%)and 5 patients(14.3%)of the TXA group and the control group,respectively(P=0.35).More patients in the TXA group(21 cases,60%)received blood transfusion than the control group(8 cases,22.9%)(P=0.02).Conclusions:TXA did not improve the outcome of patients with acute upper GI bleeding.

Association between community-acquired pneumonia and platelet indices: A case-control study
