Overview

The goal of this clinical trial is evaluating the efficacy and safety of Lianxiaxiaopi Granules in participant population. The main questions it aims to answer are: 1. Based on the Response rate of postprandial distress syndrome participants, evaluate whether the efficacy of Lianxiaxiaopi Granules is superior to placebo. 2. Evaluate the efficacy of Lianxiaxiaopi Granules in improving symptom of postprandial distress syndrome. 3. Evaluating the safety of Lianxiaxiaopi Granules in postprandial distress syndrome participants.

Outcomes

Primary Outcomes

Postprandial distress syndrome response rate

Postprandial Distress Syndrome Response, the number of weeks in which the subject responded to the postprandial distress syndrome was greater than 50% of the weeks throughout the treatment period. Response week, if the two symptoms of postprandial fullness and discomfort and early satiety decreased by ≥50% compared with the baseline per week, the response week was calculated by the diary card score.

Time frame: The end of Week 8

Secondary Outcomes

postprandial distress syndrome score change from baseline

"The dyspepsia symptom scoring criteria" consists of 5 items, with a minimum score of 0 and a maximum of 10 points for each item. 0 points: asymptomatic; 1-3 points: mild disturbance, mild symptoms, almost no impact on daily life and work; 4-6 points: moderate disturbance, still tolerable, partially affecting daily life and work; 7-10 points: Severe disturbance, unbearable, unable to carry out daily life and work. The minimum score of the scale is 0 points, the maximum is 50 points, and the higher the score, the more serious the disease.

Time frame: The end of Week 8

single symptom response rate

Time frame: The end of Week 8

the change value of single symptom score from baseline

Time frame: The end of Week 8

the change from baseline in epigstric pain syndrome score

"The dyspepsia symptom scoring criteria" consists of 5 items, with a minimum score of 0 and a maximum of 10 points for each item. 0 points: asymptomatic; 1-3 points: mild disturbance, mild symptoms, almost no impact on daily life and work; 4-6 points: moderate disturbance, still tolerable, partially affecting daily life and work; 7-10 points: Severe disturbance, unbearable, unable to carry out daily life and work. The score for epigastric pain syndrome includes the sum of the scores for mid-upper quadrant pain and mid-upper quadrant burning sensation

Time frame: The end of Week 8

epigastric pain syndrome response rate

Time frame: The end of Week 8

the change from baseline in the total score of TCM

The TCM Syndrome Scale for Postprandial Distress Syndrome contains two main symptoms, each of which can be evaluated as 0, 2, 4 and 6 points. 6 sub-symptoms, each of which can be evaluated as 0, 1, 2, and 3 points. The scale has a minimum score of 0 and a maximum of 30 points, with the higher the score, the more severe the condition.

Time frame: The end of Week 8

TCM syndrome integral effective rate

Recovery: Symptoms and signs disappear or basically disappear, and the score reduction rate of the syndrome ≥95%; Effective: Symptoms and signs improved, and the score reduction rate of the syndrome was ≥50%; Ineffective: no significant improvement in symptoms and signs, and the score reduction rate of the syndrome \<50%. Recovery: Symptoms and signs disappear or basically disappear, and the score reduction rate of the syndrome ≥95%; Effective: Symptoms and signs improved, and the score reduction rate of the syndrome was ≥50%; Ineffective: no significant improvement in symptoms and signs, and the score reduction rate of the syndrome \<50%. Recovery: Symptoms and signs disappear or basically disappear, and the score reduction rate of the syndrome ≥95%; Effective: Symptoms and signs improved, and the score reduction rate of the syndrome was ≥50%; Ineffective: no significant improvement in symptoms and signs, and the score reduction rate of the syndrome \<50%.

Time frame: The end of Week 8

the grade change of TCM single symptom from baseline

Time frame: The end of Week 8

the proportion of subjects with sustained remission and no exacerbation of single symptoms at 12W compared with 8W

There are 5 items in the Likert scale, with a minimum score of 1 and a maximum of 7 points for each item. The scale has a minimum score of 0 and a maximum of 35 points, with higher scores and more severe conditions. Among them, the subjects selected (1) and (2) are defined as having sustained remission from treatment; Subjects selected (3) and (4) were defined as having no exacerbation of disease; Subjects selected (5), (6), and (7) were defined as having exacerbated disease.
