研究目的:

明目消朦片(MMXM)作为一种中药,已显示出对糖尿病性黄斑水肿(DME)的保护作用。铁死亡是一种铁依赖性的程序性细胞死亡途径,在DME的发病机制中发挥作用。本研究结合临床观察、网络药理学及实验验证,以探究明目消朦片治疗DME的疗效及作用机制。

Objectives of Study:

Mingmu Xiaomeng Tablets (MMXM) a traditional Chinese medicine have shown protective effects against diabetic macular edema (DME). Ferroptosis an iron-dependent regulated cell death pathway plays a role in DME pathogenesis. This study combines clinical observations network pharmacology and experimental validation to explore the efficacy and mechanisms of MMXM in treating DME.

药物成份或治疗方案详述:

明目消朦片是我院全国名中医张梅芳教授带领团队率先提出并应用于DME防治的中药方剂。张教授根据“益气养阴,活血祛痰”的治疗原则,结合临床经验,创新性地自拟了明目消朦片(院内制剂批准文号:粤药制字Z20080115),并在临床上取得了显著疗效。明目消朦片是由多种中草药制成的,包括党参、麦冬、五味子、茯苓、陈皮、法半夏、竹茹、枳实、三七等。共纳入31患者,随机分为(1)对照组(康柏西普组):玻璃体腔注射康柏西普,剂量:0.05ml,连续治疗3个月,每月一次。(2)联合治疗组(明目消朦片口服联合康柏西普组):玻璃体腔注射康柏西普,剂量:0.05ml,连续治疗3个月,并给予口服明目消朦片(院内制剂批准文号:粤药制字Z20080115)每次4片,每日3次,连续治疗3个月。治疗前所做检查:基本信息采集,视力、眼压、OCT、OCTA、房水炎症因子检测。 疗后3个月:视力、眼压、OCT、OCTA、房水炎症因子检测,期间电话随访。

随机方法(请说明由何人用什么方法产生随机序列):

研究人员利用SPSS软件输入受试者数量和分组信息,由计算机生成随机分配方案。每位受试者的随机编号决定其治疗组别,并在整个研究过程中作为其唯一标识。符合条件的受试者依序打开与其编号相匹配的信封,信封内含有随机分配卡,由指定人员管理。研究人员根据卡片上的分组进行相应治疗,严禁更改。系统分配的编号“1”代表对照组,“2”代表联合治疗组。

Randomization Procedure (please state who generates the random number sequence and by what method):

The researchers used SPSS software to input the number of subjects and grouping information and the computer generated a random allocation scheme. The random number of each subject determined their treatment group and served as their unique identifier throughout the study. Eligible subjects sequentially opened the envelopes matching their numbers. Each envelope contained a random allocation card which was managed by a designated person. The researchers carried out the corresponding treatment according to the grouping on the card and any changes were strictly prohibited. The system - assigned number "1" represented the control group and "2" represented the combination treatment group.
