Abstract
目的分析胃食管反流病患者症状发生与酸及胆汁反流事件之间的关系,以确定胆汁反流是否与酸反流同样为引起胃食管反流症状的主要原因.方法对32例有胃食管反流病典型症状(烧心、反食、反酸)患者和24h食管内 pH及胆汁同步监测.监测中患者均完成日记,内容包括进餐的时间和食物内容,卧位和直立位时间及症状.并通过症状标记按键进行症状标记.通过计算机分析结果以DeMesster计分1 4.72为标准将患者分成两组:1组为无明显酸反流组(14例,56.25%),2组为有明显酸反流组(18例,43.75%).分析两组患者所标记的症状发生的时间(餐时,餐后,直立位,卧位 );是否与酸反流事件或胆汁反流事件或酸和胆汁混合反流事件有关.如果症状发生前后2mi n内食管内pH＜4持续10s以上则表明症状与酸反流有关;症状发生前后2min内食管内胆红素吸收值＞0.14持续10s以上则表明症状与胆汁反流有关.计算每一例患者的酸反流和胆汁反流有关的症状指数(symptom index SI).与酸反流有关的症状指数SI=(与酸相关的症状次数)/(总的症状次数)×100%,与胆汁反流有关的症状指数SI=(与胆汁相关的症状次数)/(总的症状次数)×100%.结果 32例患者监测中共发生症状272次(包括烧心、反酸、胸痛、反食).第 1组患者人平症状发生次数低于第2组(5.1 vs 11.3).第2组仅18次(2.7%)的症状发生与酸反流有关,而第2组有102次(50.5%)的症状发生与酸反流有关.两组仅有7.7%的症状发生与胆汁反流有关.第1组与酸和胆汁反流有关的症状指数计分较低;而第2组与胆汁反流有关的症状指数计分亦较低,但与酸反流有关的症状指数计分明显高于第1组(P＜0.05). 结论反流症状的发生明显与酸反流事件相关而较少与胆汁反流事件相关. 胆汁反流不是导致胃食管反流症状的主要因素.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
