Pharmacotranscriptomic profiles, which capture drug-induced changes in gene expression, offer vast potential for computational drug discovery and are widely used in modern medicine. However, current computational approaches neglected the associations within gene‒gene functional networks and unrevealed the systematic relationship between drug efficacy and the reversal effect. Here, we developed a new genome-scale functional module (GSFM) transformation framework to quantitatively evaluate drug efficacy for in silico drug discovery. GSFM employs four biologically interpretable quantifiers: GSFM_Up, GSFM_Down, GSFM_ssGSEA, and GSFM_TF to comprehensively evaluate the multi-dimension activities of each functional module (FM) at gene-level, pathway-level, and transcriptional regulatory network-level. Through a data transformation strategy, GSFM effectively converts noisy and potentially unreliable gene expression data into a more dependable FM active matrix, significantly outperforming other methods in terms of both robustness and accuracy. Besides, we found a positive correlation between RS_GSFM and drug efficacy, suggesting that RS_GSFM could serve as representative measure of drug efficacy. Furthermore, we identified WYE-354, perhexiline, and NTNCB as candidate therapeutic agents for the treatment of breast-invasive carcinoma, lung adenocarcinoma, and castration-resistant prostate cancer, respectively. The results from in vitro and in vivo experiments have validated that all identified compounds exhibit potent anti-tumor effects, providing proof-of-concept for our computational approach.

Objective:To investigate the effect and necessity of aesthetic suture techniques training in improving the suture quality of non-plastic surgeons.Methods:The well-planned aesthetic suture techniques training programs were run in non-plastic surgery senior residents and attending surgeons at Peking University People＇s Hospital from January 2017 to January 2019. There were 120 senior residents and attending surgeons included (aged from 25-32 years, average 28.9 years, with 66 males and 54 females). Mixed teaching methods were used such as video shows, lectures, surgery live show and scenario simulation. Baseline tests were taken before the training. Suture quality tests were taken when the trainings came to the end. Self-assessments were carried out both before and after the trainings.Results:Eight rounds of aesthetic suture techniques training were accomplished and 120 trainees were included in all. One hundred and two trainees passed the test while eight failed, while 10 trainees were absent in some courses or the final test. The passing rate was 85.0%. The scales of suture tools and material selection, incision design, subcutaneous tissue suture quality, tension relaxation, aesthetic suture appearance, and flexibility of different suture techniques were sharply improved after the training in both subjective and objective assessments.Conclusions:The aesthetic suture techniques training is effective in improving the suture quality of non-plastic surgeons, which is worthy to generalize in resident training.
