The technical problems and approval standards for the regional test of soybean varieties in Liaoning Province were discussed. The technical key points for the soybean regional trials were the selection of trial fields, preparations in lab be-fore sowing, preparations in regional trial field before sowing, sowing in suitable time and strict with sowing process, field management and survey record, harvest and sampling as wel as lab test and summary. In addition, the approval standards for common varieties and quality varieties for the soybean regional trials in Liaoning were introduced, with the aim to provide accurate and scientific theoretical basis for the approval of soybean varieties. 展开更多

AIM: To evaluate the technical failures of the Bravo pH test in a population with nonerosive gastroesophageal reflux disease. METHODS: Over the course of a year, we prospectively studied a population of 66 nonerosive reflux disease patients who received a Bravo pH test. The number and frequency of all technical failures were documented, quantified and analyzed. RESULTS: A total of 66 patients, with a mean age of 41.7 years, were studied. Technical failures occurred in 15.15% of the sample. The most frequent failures were due to poor data reception (4.5%), early dislodgement (4.5%) and capsule removal (6.1%). CONCLUSION: The Bravo capsule pH test involves a low but non-negligible rate of technical problems, a fact that must always be considered by physicians. 展开更多
