我们提出了一种使用推拿操作模拟器对轻微慢性缩窄损伤大鼠进行"三手三穴"推拿治疗的方案，并通过行为分析测试疼痛变化和使用酶联免疫吸附测定法测试炎症因子表达的变化来评估 24 小时内推拿的有效镇痛时间点。
我们的研究范围属于推拿疗法治疗神经性疼痛的疗效验证和机制探索。我们想通过动物实验来解答推拿的疗效，为推拿在临床实践中的镇痛效果提供科学依据。目前，RNA 测序、钙成像和分子生物学技术被用于促进该领域的进一步研究。
干预后 24 小时内推拿的镇痛效果在不同时间点存在显著差异。这为后期三法三穴"推拿镇痛"启动机制的研究选择合适的行为时间点和采样提供了科学依据。该研究方案进一步验证了三法三穴推拿技术的即时和持续镇痛效果，为后期探索推拿镇痛的启动机制提供了更准确的时间点。
在后续研究中，我们将继续重点探索推拿镇痛的启动机制，以期为临床推拿治疗神经性疼痛相关疾病提供科学依据。

Biopharma FAQs
Why does null hypothesis testing of tuina analgesia matter for target validation?
Null hypothesis testing using behavioral and cytokine endpoints ensures that observed analgesic effects are statistically robust, supporting functional target validation and reducing false positives in early discovery.
How does independent variable isolation in pain threshold assays fit the discovery pipeline?
Isolating tuina intervention as the independent variable in CST, MWT, and TWL assays clarifies causal relationships, enabling mechanistic de-risking and informing candidate selection in analgesic discovery workflows.
What do quantitative dependent variable measurements like CST, MWT, and TWL enable?
Quantitative measurements of pain thresholds provide objective, reproducible data for comparing intervention efficacy, supporting data-driven triage and advancement decisions in preclinical analgesic pipelines.
Why are replication requirements in behavioral and cytokine assays critical for cross-functional collaboration?
Replication ensures that analgesic effects observed in pain and cytokine assays are reliable and transferable, facilitating cross-team data integration and confidence in portfolio progression.
What statistical analysis capabilities are required before implementing tuina efficacy endpoints?
Robust statistical analysis is needed to compare intervention and control groups across time points, validate significance of analgesic effects, and support regulatory and translational reporting standards.
