Outcome Measures
Primary Outcome Measures
- Abdominal pain intensity [Recorded daily by patients from baseline to day56]
the most severe abdominal pain score in the past 24 hours, with a weekly mean decrease of at least 30% from baseline;
- Improvement of stool characteristics [Recorded daily by patients from baseline to day56]
Record daily by symptom diary card.Stools were recorded according to Bristol Stool Chart.
Secondary Outcome Measures
- Frequency of abdominal pain [Recorded daily by patients from baseline to day56]
Number of abdominal pain
- IBS symptom severity scale（IBS-SSS） [Baseline and days 14，28，56]
The IBS symptom severity questionnaire consists of four questions on a 100-point scale, with the highest score being 100 and the lowest being 0. The higher the score, the more severe the symptoms.
- IBS Quality of Life Scale（IBS-QOL） [Baseline and days 14，28，56]
The IBS Quality of Life scale has 34 questions, and adopts a five-level scoring system, with the highest score of 4 points and the lowest score of 0 points. The higher the score, the more serious it is.
- Self-rating Anxiety Scale（SAS) [baseline and day56]
There are 20 questions in the self-rating anxiety scale, which is graded at four levels, with the highest score being 4 and the lowest score being 1. The higher the score is, the more serious it is.
- Self-rating Depression Scale(SDS) [baseline and day56]
There are 20 questions in the Self-rating Depression Scale, which is graded at four levels, with the highest score being 4 and the lowest score being 1. The higher the score is, the more serious it is.
- Emergency drug use [Emergence，baseline and days 14，28，56]
Subjects may take Piaverium bromide tablets 3-4 tablets per day if they feel unbearable abdominal pain, and increase to 6 tablets per day if necessary.
