结局指标
主要结局
The Change of BPI-SF at visit8
时间窗: Visit8, visit8 taking place at week 4 or after early discontinuation/withdrawal from study
Brief pain inventory short-form(BPI-SF) recorded at final visit assesses subject's average pain over the last 24 hours. score range is 0(no pain)-10(pain as bad as you can imagine).Do higher values represent a worse outcome.
The Change of BFI-Bowel Function Index at visit8
时间窗: Visit8, visit8 taking place at week 4 or after early discontinuation/withdrawal from study
BFI is the mean of NAS for the following items: * Ease of defecation * Feeling of incomplete bowel evacuation. * Personal judgment of constipation. NAS was a measure of 0-100 where 0 was easy/no difficulty/not at all and 100 was severe difficulty/very strong,total score range is 0-300.Do higher values represent a worse outcome.
次要结局

- The Change of Individual Items in BPI-SF(Except for Pain in Average) by Visit(visit2 (day 0) to visit8 (week 4 or early discontinue/withdrawal from study))
- The Change of Bowel Movement by Visit(visit2 (day 0) to visit8 (week 4 or early discontinue/withdrawal from study))
