+## 📋 文档说明
+
+本文档描述AI智能文献模块的数据库设计，包括数据表结构、关系设计、索引设计等。
+
+---
+
+## 🗄️ 核心数据表
+
+### 1. 文献筛选项目表 (literature_screening_projects)
+
+```sql
+CREATE TABLE literature_screening_projects (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  user_id UUID NOT NULL REFERENCES users(id),
+  project_name VARCHAR(255) NOT NULL,
+  protocol_id UUID, -- 研究方案ID（未来关联）
+  
+  -- PICO标准
+  pico_criteria JSONB, -- PICO结构化数据
+  
+  -- 筛选标准
+  inclusion_criteria TEXT,
+  exclusion_criteria TEXT,
+  
+  -- 状态
+  status VARCHAR(50) DEFAULT 'draft', -- draft, screening, completed
+  
+  -- 筛选配置
+  screening_config JSONB, -- 筛选配置（双模型选择等）
+  
+  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+### 2. 文献条目表 (literature_items)
+
+```sql
+CREATE TABLE literature_items (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  project_id UUID NOT NULL REFERENCES literature_screening_projects(id) ON DELETE CASCADE,
+  
+  -- 文献基本信息
+  pmid VARCHAR(50),
+  title TEXT,
+  authors TEXT,
+  journal VARCHAR(255),
+  publication_year INTEGER,
+  doi VARCHAR(255),
+  abstract TEXT,
+  
+  -- 文件信息
+  full_text_file_path VARCHAR(500),
+  full_text_status VARCHAR(50), -- not_required, pending, downloaded, uploaded, failed
+  
+  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  
+  UNIQUE(project_id, pmid)
+);
+```
+
+### 3. 标题摘要初筛结果表 (title_abstract_screening_results)
+
+```sql
+CREATE TABLE title_abstract_screening_results (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  project_id UUID NOT NULL REFERENCES literature_screening_projects(id) ON DELETE CASCADE,
+  literature_item_id UUID NOT NULL REFERENCES literature_items(id) ON DELETE CASCADE,
+  
+  -- DS模型判断
+  ds_p_judgment VARCHAR(10), -- ✓, ✗, ?
+  ds_i_judgment VARCHAR(10),
+  ds_c_judgment VARCHAR(10),
+  ds_s_judgment VARCHAR(10),
+  ds_conclusion VARCHAR(20), -- include, exclude
+  
+  -- DS模型证据
+  ds_p_evidence TEXT,
+  ds_i_evidence TEXT,
+  ds_c_evidence TEXT,
+  ds_s_evidence TEXT,
+  
+  -- Q3模型判断
+  q3_p_judgment VARCHAR(10),
+  q3_i_judgment VARCHAR(10),
+  q3_c_judgment VARCHAR(10),
+  q3_s_judgment VARCHAR(10),
+  q3_conclusion VARCHAR(20),
+  
+  -- Q3模型证据
+  q3_p_evidence TEXT,
+  q3_i_evidence TEXT,
+  q3_c_evidence TEXT,
+  q3_s_evidence TEXT,
+  
+  -- 冲突状态
+  conflict_status VARCHAR(20) DEFAULT 'none', -- none, conflict, resolved
+  
+  -- 最终决策
+  final_decision VARCHAR(20), -- include, exclude, pending
+  final_decision_by UUID REFERENCES users(id),
+  final_decision_at TIMESTAMP,
+  exclusion_reason TEXT,
+  
+  -- AI处理状态
+  ai_processing_status VARCHAR(50) DEFAULT 'pending', -- pending, processing, completed, failed
+  ai_processed_at TIMESTAMP,
+  
+  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  
+  UNIQUE(project_id, literature_item_id)
+);
+```
+
+### 4. 筛选任务表 (screening_tasks)
+
+```sql
+CREATE TABLE screening_tasks (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  project_id UUID NOT NULL REFERENCES literature_screening_projects(id) ON DELETE CASCADE,
+  
+  task_type VARCHAR(50) NOT NULL, -- title_abstract, full_text
+  status VARCHAR(50) DEFAULT 'pending', -- pending, running, completed, failed
+  
+  total_items INTEGER,
+  processed_items INTEGER DEFAULT 0,
+  success_items INTEGER DEFAULT 0,
+  failed_items INTEGER DEFAULT 0,
+  
+  started_at TIMESTAMP,
+  completed_at TIMESTAMP,
+  error_message TEXT,
+  
+  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+---
+
+## 📊 数据关系图
+
+```
+literature_screening_projects (1) ──< (N) literature_items
+literature_screening_projects (1) ──< (N) title_abstract_screening_results
+literature_items (1) ──< (1) title_abstract_screening_results
+literature_screening_projects (1) ──< (N) screening_tasks
+```
+
+---
+
+## 🔍 索引设计
+
+```sql
+-- 文献条目表索引
+CREATE INDEX idx_literature_items_project_id ON literature_items(project_id);
+CREATE INDEX idx_literature_items_pmid ON literature_items(pmid);
+
+-- 筛选结果表索引
+CREATE INDEX idx_screening_results_project_id ON title_abstract_screening_results(project_id);
+CREATE INDEX idx_screening_results_item_id ON title_abstract_screening_results(literature_item_id);
+CREATE INDEX idx_screening_results_conflict ON title_abstract_screening_results(conflict_status);
+CREATE INDEX idx_screening_results_decision ON title_abstract_screening_results(final_decision);
+
+-- 任务表索引
+CREATE INDEX idx_screening_tasks_project_id ON screening_tasks(project_id);
+CREATE INDEX idx_screening_tasks_status ON screening_tasks(status);
+```
