What's inside
- Skill name
aact-bulk-trials- Description
- 使用 AACT (Aggregate Analysis of ClinicalTrials.gov) PostgreSQL 数据仓库进行批量、历史、聚合性临床试验数据挖掘。Use this skill when the user requests bulk SQL analysis over the full clinical trials data warehouse — historical trial trends, disease landscapes, similar-design matching, or multi-year aggregations across hundreds of thousands of NCT records. 触发场景包括:AACT 查询、临床试验批量分析、PostgreSQL 试验数据、全量 NCT 检索、试验数据挖掘、历史试验分析、clinical trials data warehouse、SQL trials、bulk trial analysis、disease landscape、试验设计相似性匹配、跨年度聚合、sponsor/phase/country 多维统计。**与 clinical-trials-v2 差异**:本 skill 走批量 SQL · 离线大数据(PostgreSQL);v2 走实时 API · 单查询。两者互补:单条 NCT 实时状态用 v2,百万级历史挖掘用本 skill。支持云端公共 PostgreSQL(aact-db.ctti-clinicaltrials.org · 零部署)和每日 dump 本地还原(高性能 · 离线)两种连接方式,自动检测优先用本地。跨平台(macOS/Linux/Windows)参数化 SQL 防注入,read-only 强制保护。

# AACT Bulk Trials · 批量临床试验数据仓库
## 1. 何时调用本 skill
**调用本 skill** 当用户请求:
- 疾病领域全景分析("过去 10 年血液病所有 NCT 试验按 phase/sponsor 聚合")
- 跨年度趋势聚合("AML 领域 III 期试验赞助商分布")
- 设计相似试验匹配("找与 NCT12345678 设计相似的其他试验")
- 整库扫描 / 百万级 JOIN(条件 + 干预 + 结果跨表)
**不要调用本 skill**(应转其他):
- 单条 NCT 最新状态查询 → `clinical-trials-v2`(实时 API · 互补)
- 文献检索 → `pubmed-search` / `europepmc-search`
- 临床报告撰写 → `clinical-reports`
**与 clinical-trials-v2 的差异**:
| 维度 | clinical-trials-v2 | aact-bulk-trials(本 skill) |
|------|-------------------|----------------------------|
| 数据源 | ClinicalTrials.gov v2 REST API | AACT PostgreSQL 镜像(每日同步) |
| 单次容量 | ≤ 1000 条 | 单 SQL 可处理百万级 |
| 网络 | 强依赖 | 本地模式离线可用 |
| 延迟 | 低(实时) | T+1(每日 dump) |
| 适用场景 | 单试验细节、最新状态 | 批量聚合、历史趋势、跨表 JOIN |
---
## 2. 上下游 skill 协作
```
clinical-trials-v2 ────┐
(实时单查 · 互补) │
▼
aact-bulk-trials → medical-evidence-grading → evidence-appendix-sync
(本 skill · 批量SQL) (上层 · 批量 grade) (终下游 · 报告附录)
```
- **上游**:用户原始批量挖掘需求(市场调研、疾病全景、设计相似性)
- **平级互补**:`clinical-trials-v2`(单条实时) / `pubmed-search`(文献)
- **下游**:`medical-evidence-grading`(用本 skill 输出的 NCT 列表批量评级) → `evidence-appendix-sync`(终态报告附录 C)
---
## 3. 核心能力速查(5 个 SQL 模板)
所有签名见 `references/sql-templates.md`,参数化 SQL 防注入,默认 `LIMIT 1000`。
| 函数 | 签名(参数) | 用途 |
|------|------------|------|
| `query_trials_by_condition` | `(condition_term, year_from, year_to, phase, limit)` | 按适应症 + 年份 + phase 检索 |
| `query_trials_by_intervention` | `(intervention_name, intervention_type, limit)` | 按干预名 + 类型检索 |
| `query_trials_results_summary` | `(nct_id_list)` | 已上传 results 的试验统计摘要 |
| `bulk_disease_landscape` | `(disease_term, year_from, year_to)` | 疾病四维聚合(phase/status/sponsor/国家) |
| `find_similar_design_trials` | `(reference_nct_id, limit)` | 设计相似试验匹配 |
完整 SQL 见 → `references/sql-templates.md`
---
## 4. 双连接快速决策
skill 启动时自动检测:**本地 dump (B) → 云端 (A) → 报错指引**。
| 模式 | 何时用 | 性能 |
|------|--------|------|
| 本地 dump(B) | 批量挖掘 / 整库扫描 / 跨年度聚合 | 典型 < 5s |
| 云端公共(A) | 偶发查询 / 无本地 PostgreSQL | 200ms - 2s |
部署细节、yaml 配置、密钥管理、read-only 强制 → `references/connection-setup.md`
Schema 关系图、关键表速查、字段陷阱、推荐 GIN 索引 → `references/aact-schema.md`
---
## 5. 工作流(Decision Tree)
```
用户请求
│
├─ 单条 NCT 实时? → 转 clinical-trials-v2
├─ 文献需求? → 转 pubmed-search
│
└─ 批量 / 历史 / 聚合? → 本 skill
│
├─ 1. 检测连接(local → cloud → 报错)
├─ 2. 解析意图,匹配 5 个 SQL 模板之一
├─ 3. 参数校验(phase 枚举 / 日期合法 / LIMIT 上限 / NCT 格式 ^NCT\d{8}$)
├─ 4. 大查询先 EXPLAIN (ANALYZE, BUFFERS) 评估
├─ 5. 执行 + 流式取数(>50K 行用 server-side cursor)
├─ 6. 后处理(去重、聚合、JSON 序列化)
└─ 7. 返回结构化结果 + meta(耗时、命中行数、来源 mode、snapshot 日期)
```
---
## 6. 失败模式与处置
| 现象 | 根因 | 处置 |
|------|------|------|
| 云连接超时 / SSL 错误 | 网络限制或 AACT 服务波动 | 切换 `mode: local`;或加 `sslmode=require` 重试 |
| `psql: connection refused`(本地) | 本地 PostgreSQL 未启动 | macOS: `brew services start postgresql@16` / Linux: `sudo systemctl start postgresql` / Windows: `Start-Service postgresql-x64-16` |
| `password authentication failed` | 凭据错误或环境变量缺失 | 检查 `$AACT_*` 环境变量;引导访问 https://aact.ctti-clinicaltrials.org/users/sign_up |
| `relation "xxx" does not exist` | AACT schema 年度变更(每年 1-2 次) | 对照 https://aact.ctti-clinicaltrials.org/release_notes 校准列名 |
| 查询无返回但 ClinicalTrials.gov 有 | T+1 数据延迟(当日新建试验未入 dump) | 转 `clinical-trials-v2` 实时 API |
| OOM / 客户端被 kill | 一次性拉百万行到内存 | 改用 server-side cursor `cursor(name='aact_stream')` 或加 LIMIT 分页 |
| `statement timeout`(120s) | 查询无索引或选择性差 | 检查 EXPLAIN;建 GIN trigram 索引;或临时 `SET LOCAL statement_timeout = 0` |
| `cannot execute DROP/DELETE in read-only transaction` | 用户/prompt 注入了破坏性 SQL | **正确行为**:read-only 模式拦截了误操作;不要绕过,检查输入来源 |
