研究目的: |
本研究拟以膝关节骨性关节炎(knee osteoarthritis,KOA)为研究对象,整合公开转录组与单细胞测序数据,从二聚体活性与瘦素相关基因入手,系统刻画其在KOA滑膜组织中的异常表达特征、细胞类型特异性分布及潜在互作关系,并结合实验验证,阐明其参与KOA发生发展与修复障碍的分子机制,为KOA的潜在诊断标志物筛选与靶向干预提供理论依据。 |

|
Objectives of Study: |
This study focuses on knee osteoarthritis (KOA). By integrating public bulk RNA sequencing and single-cell RNA sequencing data, we will systematically characterize the abnormal expression patterns, cell-type-specific distribution, and potential interactions of genes related to dimer activity and leptin within the KOA synovium. Combined with experimental validation, this research aims to elucidate the molecular mechanisms through which these genes contribute to the pathogenesis, progression, and impaired repair processes in KOA. The findings are expected to provide a theoretical basis for the identification of potential diagnostic biomarkers and the development of targeted therapeutic interventions for KOA. |

纳入标准: |
KOA组纳入标准: (1)年龄≥40岁,性别不限。 (2)符合膝关节骨性关节炎临床诊断标准,具有典型症状体征(如膝痛、僵硬、活动受限等),并有影像学支持。 (3)影像学提示膝骨关节炎改变,Kellgren–Lawrence(K-L)分级≥2级,或存在明确的软骨退变/骨赘形成等证据。 (4)因KOA接受关节镜下清理、截骨或关节置换等手术治疗,术中可获取足量滑膜组织。(5)近期无急性全身感染或其他严重系统性疾病影响关节炎症状态。 对照组(单纯半月板损伤)纳入标准: (1)年龄18–60岁,性别不限。 (2)临床与影像学明确诊断为半月板损伤,因症状明确拟行关节镜手术治疗。 (3)膝关节影像学无骨关节炎证据或退变程度轻微:K-L分级0–1级,软骨退变不超过轻度范围。 (4)无明确滑膜炎相关系统性疾病史,术中可获取足量滑膜组织。 |

Inclusion criteria |
Inclusion Criteria for the KOA Group: (1) Age >= 40 years, any gender. (2) Meeting the clinical diagnostic criteria for knee osteoarthritis, presenting with typical symptoms and signs (e.g., knee pain, stiffness, limited mobility), supported by imaging evidence. (3) Imaging findings indicative of knee osteoarthritis changes, with a Kellgren-Lawrence (K-L) grade >= 2, or clear evidence of cartilage degeneration/osteophyte formation. (4) Undergoing surgical treatment for KOA, such as arthroscopic debridement, osteotomy, or joint replacement, during which sufficient synovial tissue can be obtained. (5) No recent acute systemic infection or other severe systemic diseases affecting the inflammatory state of the joint. Inclusion Criteria for the Control Group (Simple Meniscus Injury): (1) Age 18–60 years, any gender. (2) Clinically and radiologically confirmed diagnosis of meniscus injury, scheduled for arthroscopic surgery due to definitive symptoms. (3) No imaging evidence of osteoarthritis or only minimal degenerative changes in the knee joint: K-L grade 0–1, with cartilage degeneration, if present, not exceeding a mild range. (4) No history of systemic diseases associated with definite synovitis, and sufficient synovial tissue can be obtained during the surgery. |

排除标准: |
KOA组排除标准: (1)合并其他类型关节炎或免疫系统疾病:类风湿关节炎、强直性脊柱炎、痛风/假性痛风、银屑病关节炎、系统性红斑狼疮等。 (2)近3个月内膝关节存在明显感染性关节炎证据或全身严重感染。 (3)近3个月内接受可能显著影响滑膜炎症与基因表达的治疗,包括关节腔内糖皮质激素或PRP、透明质酸等注射;系统性糖皮质激素或免疫抑制剂治疗;抗肿瘤化疗/放疗等。 (4)合并严重膝关节创伤史(如骨折、韧带重建术后短期内)或近期重大手术影响局部组织炎症反应。 (5)合并肿瘤、严重肝肾功能不全、严重心肺功能不全等可能影响整体炎症状态或手术安全的情况。 对照组(单纯半月板损伤)排除标准: (1)任何明确或疑似骨关节炎、炎症性关节病或晶体相关关节病证据。 (2)合并膝关节主要韧带断裂需重建(如ACL/PCL重建)、明显软骨广泛缺损或严重骨挫伤等复杂损伤,以避免对照组“退变/炎症背景”混入。 (3)近3个月内存在关节腔注射治疗、系统性糖皮质激素/免疫抑制剂使用或其他明显影响滑膜炎症的治疗史。 (4)既往膝关节感染、结核或肿瘤病史,或近期全身严重感染。 |

Exclusion criteria: |
Exclusion Criteria for the KOA Group: (1) Complicated by other types of arthritis or immune system diseases: rheumatoid arthritis, ankylosing spondylitis, gout/pseudogout, psoriatic arthritis, systemic lupus erythematosus, etc. (2) Evidence of significant infectious arthritis in the knee joint or severe systemic infection within the last 3 months. (3) Receipt of treatments within the last 3 months that may significantly affect synovial inflammation and gene expression, including intra-articular injections of glucocorticoids, PRP, or hyaluronic acid; systemic glucocorticoid or immunosuppressant therapy; anti-tumor chemotherapy/radiotherapy, etc. (4) History of severe knee joint trauma (e.g., fractures, short-term post-ligament reconstruction surgery) or recent major surgery affecting local tissue inflammatory response. (5) Complicated by tumors, severe hepatic or renal dysfunction, severe cardiopulmonary dysfunction, or other conditions that may affect the overall inflammatory state or surgical safety. Exclusion Criteria for the Control Group (Simple Meniscus Injury): (1) Any definitive or suspected evidence of osteoarthritis, inflammatory joint disease, or crystal-associated arthropathy. (2) Complicated by complex injuries requiring reconstruction of major knee ligaments (e.g., ACL/PCL reconstruction), obvious extensive cartilage defects, or severe bone contusions, to avoid introducing a "degeneration/inflammation background" into the control group. (3) History of intra-articular injections, systemic glucocorticoid/immunosuppressant use, or other treatments significantly affecting synovial inflammation within the last 3 months. (4) Previous history of knee joint infection, tuberculosis, or tumor, or recent severe systemic infection. |
