纳入标准:

(1)年龄≥18周岁且≤70周岁; (2)经临床和组织病理学诊断确诊的口腔白斑病,且符合以下情况之一: a)伴轻至中度异常增生; b)不伴异常增生,则患者筛选时已有至少6个月的患病史,且期间应用常规治疗效果不佳; (3)病变分布于颊、舌等相对较平坦的部位且明显可见; (4)能够理解试验的目的,愿意签署知情同意书并接受按时随访。

Inclusion criteria

(1) Aged 18 to 70 years (inclusive). (2) Clinically and histopathologically diagnosed with oral leukoplakia, meeting one of the following criteria: a) With mild to moderate dysplasia. b) Without dysplasia, but the patient has a documented history of the lesion for at least 6 months at the time of screening, with poor response to conventional therapies. (3) The lesion is located in relatively flat areas such as the buccal mucosa or tongue and is clearly visible. (4) Able to understand the study objectives, willing to provide written informed consent, and able to comply with scheduled follow-up visits.

排除标准:

(1)病理活检显示的伴重度上皮异常增生,或原位癌、浸润癌。 (2)口腔弥漫性白斑。 (3)入组前1个月内应用免疫抑制剂治疗(如术前停药满1个月及以上者除外)。 (4)治疗区域有活动性感染或开放性伤口。 (5)已存在有源植入式医疗器械如心脏起搏器、植入式心律转复除颤器(ICD)、心脏再同步治疗装置(CRT)、脊髓神经刺激器、人工耳蜗、脑深部电刺激器等。 (6)严重凝血功能障碍(血小板<50*109/L,或活化部分凝血酶时间(APTT)、凝血酶原时间(PT)高于3倍ULN,或国际标准化比率(INR)≥1.5);或有活动性出血史或明显出血倾向。 (7)瘢痕体质者。 (8)6个月内发生的心肌梗死、不稳定型心绞痛或严重心功能不全(如NYHA心功能III-IV级)。 (9)明显肝、肾功能异常(ALT、AST>1.5倍正常值上限;血肌酐>2.0 mg/dL或177 μmol/L,或接受透析治疗)。 (10)预期寿命少于12个月。 (11)不能配合治疗的精神病患者。 (12)有其他严重系统性疾病,经研究者评估不适宜接受治疗。 (13)对任何已知的药物或酒精依赖,对试验方案理解困难,不能或者不愿意按照试验方案进行随访。 (14)孕妇、哺乳期及试验期间计划怀孕。 (15)正在或计划参加其他药物或医疗器械的临床试验(上市后登记研究除外)。 (16)研究者认为有不适宜参加本次临床试验的其他情况。

Exclusion criteria:

(1) Presence of severe epithelial dysplasia, carcinoma in situ, or invasive carcinoma on pathological biopsy. (2) Diffuse oral leukoplakia. (3) Use of immunosuppressive therapy within 1 month prior to enrollment (except for those who discontinued medication at least 1 month before screening). (4) Active infection or open wound in the proposed treatment area. (5) Presence of any active implantable medical device, such as a cardiac pacemaker, implantable cardioverter-defibrillator (ICD), cardiac resynchronization therapy (CRT) device, spinal cord stimulator, cochlear implant, or deep brain stimulator. (6) Severe coagulation dysfunction (platelet count < 50 x 10?/L, or activated partial thromboplastin time (APTT) or prothrombin time (PT) > 3 times the upper limit of normal (ULN), or international normalized ratio (INR) >= 1.5); or a history of active bleeding or significant bleeding tendency. (7) Known keloid formers. (8) Myocardial infarction, unstable angina, or severe cardiac insufficiency (e.g., NYHA Class III-IV) within the past 6 months. (9) Significant hepatic or renal impairment (ALT or AST > 1.5 times ULN; serum creatinine > 2.0 mg/dL or 177 μmol/L, or undergoing dialysis). (10) Life expectancy of less than 12 months. (11) Psychiatric disorders that would preclude cooperation with the treatment. (12) Other severe systemic diseases deemed by the investigator as unsuitable for the treatment. (13) Known dependency on drugs or alcohol, difficulty in understanding the trial protocol, or inability or unwillingness to comply with the scheduled follow-ups. (14) Pregnancy, lactation, or planning a pregnancy during the trial period. (15) Current or planned participation in another drug or medical device clinical trial (post-marketing registry studies excluded).
