研究目的: |
1. 阐明 KRT23 在 HSC(肝星状细胞)活化过程中促发肝纤维化的细胞学机制:通过研究 KRT23 在 HSC 活化中的作用,揭示其如何促进纤维化的发生与进展。 2. 探讨 KRT23 与 TGF-β1/Smad2 信号通路的分子互作机制:研究 KRT23 如何调控 TGF-β1/Smad2 信号通路,进一步阐明其在肝纤维化中的分子基础。 3. 分析 KRT23 在慢性乙型肝炎(CHB)相关肝纤维化/肝硬化中的表达特征,并探索其与临床病理特征和预后的关系:通过临床样本分析,评估 KRT23 表达与肝纤维化/肝硬化的临床特征和患者预后的相关性,探索其作为潜在生物标志物的价值。 |
||||||||||||||||||||||
|
Objectives of Study: |
1. Explain the cellular mechanism by which KRT23 promotes liver fibrosis during HSC (hepatic stellate cell) activation: By studying the role of KRT23 in HSC activation, reveal how it contributes to the occurrence and progression of fibrosis. 2. Explore the molecular interaction mechanism between KRT23 and the TGF-β1/Smad2 signaling pathway: Investigate how KRT23 regulates the TGF-β1/Smad2 signaling pathway to further clarify its molecular basis in liver fibrosis. 3. Analyze the expression characteristics of KRT23 in chronic hepatitis B (CHB)-related liver fibrosis/cirrhosis and explore its relationship with clinical pathological features and prognosis: Through clinical sample analysis, evaluate the correlation between KRT23 expression and the clinical features and prognosis of liver fibrosis/cirrhosis, and explore its potential value as a biomarker. |

纳入标准: |
1. 根据国家卫生部制定的诊断标准,选取医院体检中心和门诊及住院 CHB 患者,肝癌手术者,血管瘤手术者及健康者(均签署知情同意书)。 2. 入组人员在进行实验前进行免疫十项、肝功能及 HBV DNA 检测,排除甲、丙、丁及戊肝病毒性肝炎重叠感染,排除脂肪肝、酒精性肝病、自身免疫性肝病及药物性肝炎等其他肝病及免疫系统疾病,并在入组前 6 个月内未接受任何抗病毒免疫调节等治疗。 3. 外周血样本取自体检的健康人或者门诊及住院的 CHB 患者。 4. 健康肝组织取自肝脏移植剩余样本或者手术切除肝脏血管瘤、转移性肝肿瘤时所附带的正常肝组织;肝纤维化肝脏样本取自肝穿样本(主要用于免疫组织化学检测)或者肝癌患者手术切除的癌旁组织(HBsAg 阳性、肝纤维化)。 |

|
Inclusion criteria |
1. According to the diagnostic criteria set by the National Health Commission, participants were selected from hospital physical examination centers, outpatient and inpatient CHB patients, liver cancer surgery patients, hemangioma surgery patients, and healthy individuals (all signed informed consent forms). 2. Before participating in the study, participants underwent tests including a ten-item immune panel, liver function, and HBV DNA testing to rule out co-infections with hepatitis A, C, D, and E viruses. Other liver diseases and immune system disorders such as fatty liver, alcoholic liver disease, autoimmune hepatitis, and drug-induced hepatitis were also excluded. Additionally, participants had not received any antiviral or immune-regulating treatments in the six months prior to enrollment. 3. Peripheral blood samples were collected from healthy individuals undergoing physical exams or from outpatient and inpatient CHB patients. 4. Healthy liver tissue was obtained from leftover samples from liver transplants or from normal liver tissue adjacent to surgically removed hemangiomas or metastatic liver tumors. Liver fibrosis samples were obtained from liver biopsy samples (mainly for immunohistochemical analysis) or from non-tumor tissue adjacent to liver cancer surgery specimens (HBsAg positive, with liver fibrosis). |

排除标准: |
1. 患者年龄 < 18 岁或者 > 75 岁; 2. 合并甲型、丙型、丁型或戊型病毒性肝炎感染; 3. 合并其他病因所致肝病,包括但不限于酒精性肝病、非酒精性脂肪性肝病、自身免疫性肝病、药物性肝损伤、遗传代谢性肝病等; 4. 合并人类免疫缺陷病毒(HIV)感染或其他导致免疫缺陷的疾病; 5. 入组前 6 个月内曾接受任何抗病毒治疗(如核苷[酸]类似物、干扰素)、免疫调节剂或抗纤维化治疗; 6. 经影像学或病理学证实存在肝细胞癌或其他恶性肿瘤; 7. 妊娠期或哺乳期女性; 8. 存在严重心、肺、肾等重要脏器功能不全; 9. 研究者判断不适宜参加本研究的其他情况。 |

Exclusion criteria: |
1. Patients under 18 or over 75 years old; 2. Co-infection with hepatitis A, C, D, or E virus; 3. Liver disease caused by other reasons, including but not limited to alcoholic liver disease, non-alcoholic fatty liver disease, autoimmune liver disease, drug-induced liver injury, genetic metabolic liver disease, etc.; 4. HIV infection or other diseases that cause immune deficiency; 5. Received any antiviral treatment (such as nucleos(t)ide analogs, interferon), immunomodulators, or anti-fibrosis therapy within 6 months before enrollment; 6. Presence of hepatocellular carcinoma or other malignant tumors confirmed by imaging or pathology; 7. Pregnant or breastfeeding women; 8. Severe dysfunction of key organs such as heart, lungs, or kidneys; 9. Any other conditions deemed inappropriate for participating in this study by the investigator. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This study will adopt a combination of paper case report forms (CRFs) and an electronic data capture (EDC) system. All source data (such as demographic information, medical history, laboratory test results, and imaging findings) will be initially recorded on paper CRFs by the investigators or research coordinators, and subsequently entered into the electronic database independently by two individuals. Paper informed consent forms and original medical records will be stored in locked filing cabinets for a period of no less than 15 years. The original data will not be publicly shared. If there is a reasonable academic need, a written request may be submitted to the principal investigator. |
