Deployment and Upgrade for Bioequivalence Pharmacovigilance

Data Characteristics

Bioequivalence study data primarily originates from clinical trial reports, regulatory submissions, and published academic literature. This data is typically structured in tables, containing pharmacokinetic parameters (e.g., AUC, Cmax, Tmax), statistical analysis results (e.g., 90% confidence intervals), subject demographics, and dosing regimens. The update frequency is influenced by new drug development and generic drug approvals, potentially leading to monthly or quarterly bulk additions. Document structures vary, including PDF clinical study reports and electronic submission data in XML or JSON formats. Fields include drug name, active ingredient, formulation type, dosage, batch information, subject ID, sampling time points, and plasma concentration values. Units include ng/mL, h, and μg·h/mL.

Constraints Imposed by Data Characteristics on Deployment and Upgrade

The highly structured nature of bioequivalence data, with numerous numerical fields and statistical results, places specific demands on knowledge base construction. During deployment, focus on the stability of data source connections to ensure regular acquisition of new data from clinical trial databases or regulatory platforms. Since many documents are PDFs, robust document parsing capabilities are necessary to identify and extract key data from tables. Standardizing field units is critical during data ingestion to prevent data confusion or calculation errors due to inconsistent units. Given the periodic data updates, the upgrade solution must support incremental updates and version management, for example, for retrospective analysis or re-analysis of specific batches of pharmacovigilance data. Accurate querying and analysis of pharmacokinetic parameters require FastGPT to effectively handle numerical ranges and statistical features during vectorization and retrieval.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Bioequivalence reports often contain numerous charts and raw data, leading to large file sizes.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Parsing large PDF reports can be time-consuming and requires sufficient processing time.
`Chunk size`	`800–1200 characters`	Ensures pharmacokinetic parameter tables are segmented completely, preserving contextual relationships.
`Recall count`	`Top 10 entries`	Increases the recall rate for key data and statistical results in relevant reports.
`Similarity threshold`	`0.75`	Precisely matches core elements like drug names and dosages, filtering highly relevant studies.
`Rerank result count`	`Top 5 entries`	Further refines results, prioritizing reports with significant statistical meaning or regulatory focus.

Common Pitfalls

Connection timeouts when configuring model channels typically result from firewall rules restricting FastGPT's access to external model API ports.
Slow knowledge base query responses for bioequivalence data often stem from inappropriate indexing strategies, such as failing to create effective indexes for key numerical fields.
Data format validation failures when users attempt to bulk import data via Webhook are usually due to JSON structures not conforming to the preset template, for example, missing required drugName or studyID fields.

Verification of Setup

Import a bioequivalence report PDF file containing multiple pharmacokinetic parameter tables. Confirm that all table data is correctly identified and segmented.
Query for a specific drug name and AUC value range. Verify that the returned results include conforming reports and check the accuracy of the 90% confidence interval field values.
Simulate a new clinical trial data import. Check if the knowledge base updates promptly and provides query services for the new data.
