研究目的: |
便秘是各年龄段高发消化问题,伴头痛、恶心、腹痛腹胀等症状,严重影响患者生活质量,其发病与肠道菌群失衡、肠道炎症密切相关。传统治疗如饮食调整、泻药灌肠等疗效有限,还易引发药物依赖,长期用泻药甚至会导致肠道功能、电解质及菌群进一步失调。益生菌可调节肠道菌群平衡,作为便秘新兴疗法,能改善便秘症状,且安全、效果持久,从根源护肠道、降复发,适配老人、孕妇、儿童等特殊人群。本研究选取乳酸片球菌PA53(3g/条,300亿CFU/条)为试验制剂,验证其8周干预对便秘患者症状、生活质量、肠道功能等多方面的改善效果。 |

Objectives of Study: |
Constipation is a common digestive disorder across all ages, impairing patients’ quality of life with diverse symptoms. Its pathogenesis is linked to gut microbiota imbalance and intestinal inflammation. Conventional treatments have limited efficacy and may cause drug dependence; long-term laxative use even leads to intestinal dysfunction, electrolyte imbalance and microbiota disorders. Probiotics, an emerging safe therapy, alleviate constipation by regulating gut microbiota balance and reducing inflammation, ideal for special populations. This study verifies the 8-week intervention effect of *Pediococcus acidilactici* PA53 (3g/strip, 30 billion CFU/strip) on constipation symptoms, patients’ quality of life and intestinal-related indicators. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用“双盲”法,按两级设盲法,由甲方(委托单位统计人员)与乙方(项目负责人)共同完成。 一级设盲:即产品设盲。由甲方(委托单位)制备试验产品及准备其对照产品,要求每种产品及其对照产品在外观、包装、使用说明书、产品形状、剂量、标签等方面一致,然后按照试验产品分组方法进行包装。 二级设盲:即产品装盒的编码设盲。产品装盒的编号与随机分配表的序号相同,整个设盲过程由非临床观察试验人员完成并进行完整记 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study employed a "double-blind" method, with blinding implemented at two levels, jointly conducted by Party A (the statistician of the commissioning unit) and Party B (the project leader). First-level blinding (product blinding): Party A (the commissioning unit) prepared the test products and their corresponding controls. The requirements were that each test product and its control be identical in appearance, packaging, instruction manual, product form, dosage, labeling, etc. The products were then packaged according to the test product grouping scheme. Second-level blinding (coding blinding of product packaging): The case number on the product packaging corresponded to the serial number in the randomization schedule. The entire blinding process was carried out and fully documented by personnel not involved in the clinical observation trials. |
