| 1 | Antralization at the edge of proximal gastric ulcers:Does Helicobacter pylori infection play a role?显示文摘AIM: To determine the prevalence of antralization at the edge of proximal gastric ulcers, and the effect ofH. pylori eradication on the mucosal appearances.
METHODS: Biopsies were taken from the antrum, body and the ulcer edge of patients with benign proximal gastric ulcers before and one year after treatment. Gastric mucosa was classified as antral, transitional or body type.H. pylori positive patients receivedeither triple therapy, or omeprazole.
RESULTS: Patients with index ulcers in the incisura, body or fundus (n=116) were analyzed. Antral-type mucosa was more prevalent at the ulcer edge inH. pylori-positive patients thanH.pylori-negative patients (93% vs 60%, OR=8.95,95%CI: 2.47-32.4, P=0.001). At one year, there was a significant reduction in the prevalence of antralization (from 93 % to 61%, P=0.004) at the ulcer edge in patients with H. pyloribeing eradicated. However, there was no difference in the prevalence of antralization at the ulcer edge in those with persistent infection.
CONCLUSION: H. pylori infection is associated with antralization at the edge of proximal gastric ulcers, which may be reversible in some patients after eradication of the infection. | Harry Hua-Xinag Xia Shiu Kum Lam Wai Man Wong Wayne Hsing Cheng Hu Kam Chuen Lai Sau Hing Wong Suet Yi Leung Siu Tsan Yuen Nicholas A.Wright Benjamin Chun-Yu Wong | 2003 | World Journal of Gastroenterology2003，9，6： | 2 |

| 12 | Field assessment of straw pellet combustion in improved heating stoves in rural Northeast China显示文摘Straw pellets are widely promoted and expected to be a cleaner alternative fuel to unprocessed crop residues and rawcoal in rural China.However,the effectiveness of these dissemination programs is not well evaluated.In this field study,emission characteristics of burning strawpellets,rawcoal,and unprocessed corn cobs in heating stoveswere investigated in a pilot village in Northeast China.Emission measurements covering the whole combustion cycle(ignition,flaming,and smoldering phases)shows the promotion of improved heating stoves and straw pellets could reduce pollutant emissions(e.g.,SO_(2) and CO),but increase NO_(X) and PM_(2.5) emissions compared to the initial stove-fuel use pattern in the studied area.There is a significant variance in emission characteristics between different combustion phases.The normalized emission concentrations of the different stove-fuel combinations were higher than the limits in the Chinese national standard for heating stoves,indicating that the standard is not met for real-world emissions.Coal consumption was lower than official data.Household surveys were conducted to identify the barriers to fuel and stove access associated with existing promotion strategies,management,and policies.The pilot program was of the typical“subsidy-and-policy-dependence”pattern and was unlikely to be implemented on a large scale.Technological innovation,operational optimization,and proper policies considering the local socioeconomic factors are needed to sustain the promotion of biomass straw pellets and stoves. | Yafei Liu Zhimin Li Emily Floess You Zhang Nicholas Lam Sylvester K.Mawusi Prabin Shrestha Xinghua Li Chunyu Xue Guangqing Liu | 2023 | Journal of Environmental Sciences2023，，5： | 0 |
