Objective:To evaluate the effect of low-opioid anesthesia based on combination of esketamine and dexmedetomidine on the postoperative mood in patients undergoing thoracoscopic surgery.Methods:In this randomized controlled trial, 130 American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients of either sex, aged 18-65 yr, with body mass index ≤30 kg/m 2, undergoing elective video-assisted thoracoscopic surgery, were divided into 2 groups using a random number table method: low-opioid anesthesia group and conventional opioid anesthesia group, with 65 patients in each group. The patients in two groups received either a low-opioid anesthesia based on combination of esketamine and dexmedetomidine or a sufentanil-based opioid anesthesia. Depression and anxiety were assessed using the Self-Rating Depression Scale and Self-Rating Anxiety Scale on day 1 before surgery and days 1, 3 and 7 after surgery. The intraoperative consumption of opioid, usage of vasoactive drugs, extubation time, duration of stay in the post-anesthesia care unit, Riker Sedation-Agitation Scale score after extubation, consumption of sufentanil within 24 h postoperatively, and pain score at 24 h postoperatively were recorded, and the occurrence of adverse reactions within 24 h postoperatively was also recorded. Results:Compared with conventional opioid anesthesia group, the postoperative Self-Rating Depression Scale score and incidence of depression were significantly decreased, the Self-Rating Anxiety Scale score and incidence of anxiety were decreased, the intraoperative consumption of opioid was reduced, the usage rate of metaraminol was decreased, the usage rate of nicardipine was increased, the duration of stay in the post-anesthesia care unit was shortened, the Riker Sedation-Agitation Scale score was decreased after tracheal extubation, the consumption of sufentanil was reduced after operation, the pain score was decreased, and the incidence of postoperative nausea and vomiting and dizziness was decreased in low-opioid anesthesia group ( P<0.05). Conclusions:The low-opioid anesthesia based on combination of esketamine and dexmedetomidine can relieve the postoperative depression and anxiety and improve the quality of postoperative recovery when used in patients undergoing thoracoscopic surgery.

Objective    To reveal the potential mechanism of cisplatin resistance in non-small cell lung cancer A549 cells by comparing the expression profiles of wild-type A549 cells and cisplatin-resistant A549 cells (A549/DPP) through whole transcriptome sequencing analysis. Methods    The cisplatin resistant A549 (A549/DDP) cell line was first established. Then, the whole-transcriptome analysis was conducted both on A549 and A549/DDP cells. Next, the differentially expressed RNAs of lncRNA-seq, circRNA-seq, and miRNA-seq data were identified, respectively, followed by functional enrichment analysis. Finally, a comprehensive analysis based on the whole transcriptome data was performed and the construction of the ceRNA network was carried out. Results    A total of 4 517 lncRNA, 123 circRNA, and 145 miRNA were differentially expressed in A549/DDP cells compared with the A549 cell line. These different RNAs were significantly enriched in cancer-related pathways. The ceRNA network contained 12 miRNAs, 4 circRNAs, 23 lncRNAs, and 9 mRNA nodes, of which hsa-miR-125a-5p and hsa-miR-125b-5p were important miRNAs based on the topological analysis. Conclusion    Tumor necrosis factor signaling pathway and p53 signaling pathway are involved in A549/DPP resistance. Hsa-miR-125a-5p and hsa-miR-125b-5p may be potential targets for reversing cisplatin resistance.

Based on the bioinformatics and some frontier science for recent years, the new ideas and methods were used to improve the study of Chinese herbal medicine. Advances in DNA sequencing, prediction of gene, evolution and mutation, prediction of protein structure, biological chip technique, drug target and prediction of drug structure, simulation of metabolism, and the distribution of energy in pharmacological process showed the prospect of the study of Chinese medicinal plants. Some new areas about sources and pharmacology of Chinese herbal medicine are coming into being, especially the relationship between drug targets and drug structure, between simulation of metabolism and pharmacology, and between energy and pharmacology.
