Effect of AGEs-RAGE system on the efficacy of PD-1 inhibitors in the treatment of driver-gene mutation negative advanced non-squamous non-small cell lung cancer.

To observe the therapeutic effect of PD-1 inhibitors on driver-gene mutation negative advanced non-squamous non-small cell lung cancer (nsNSCLC) and the role of the AGEs-RAGE system in the disease, provide more reliable treatment for future nsNSCLC patients. In this study, we selected 130 nsNSCLC patients admitted between January 2021 and April 2022 were selected as the study subjects, 61 of whom received pemetrexed plus carboplatin (control group) and 69 received PD-1 inhibitors, pemetrexed and carboplatin (research group). The clinical efficacy and adverse reactions of the two groups were compared, and the prognostic survival time was calculated. The results show that two groups were not statistically different in objective response rate (ORR) and incidence of adverse reactions, but the disease control rate (DCR) was higher in the research group (P<0.05). Besides, the median progression-free survival (PFS) was prolonged in the research group compared with the control group (P<0.05). In addition, changes in the levels of T lymphocyte subsets, AGEs and RAGE before and after treatment were detected, and the relationship between AGEs-RAGE and the therapeutic effect of PD-1 inhibitors was analyzed. The research group also showed higher CD3+, CD4+ and lower CD8+, AGEs and RAGE levels than the control group after treatment (P<0.05). Finally, we found that in addition, the efficacy of the study group was inversely related to AGEs and RAGE levels (P<0.05). With these results, we concluded that PD-1 inhibitors are effective in the treatment of driver-gene mutation negative advanced nsNSCLC, and the AGEs-RAGE system may provide a more reliable guarantee for the treatment outcomes of patients in the future.

Data mining-based analysis on medication rules of Chinese herbal medicine treating headache with blood stasis syndrome.

Objective: The incidence of headaches with blood stasis syndrome has increased. Herein, we used scientific, statistical methods to explore the medication rules of Chinese herbal medicines (CHMs) to treat headaches with blood stasis syndrome and provide a scientific and reliable theoretical basis for clinical treatment. Methods: First, we retrieved studies related to CHMs used to treat headaches with blood stasis syndrome from the VIP, CNKI, Wanfang, and PubMed databases. We used Excel 2013 to establish a database and SPSS Modeler 18.0 and SPSS 25.0 to conduct frequency, association rule, and cluster analyses. Results: Based on the screening criteria, we retrieved 126 CHM prescriptions for headaches with blood stasis syndrome involving 149 herbs. The top three high-frequency herbs were Chuanxiong Rhizoma (Chuanxiong), Angelica Sinensis Radix (Danggui), and Carthami Flos (Honghua). Blood-activating and stasis-eliminating herbs were the most frequently used herb efficacy categories. The liver meridian represented the most frequently used herb meridian tropism. The properties and taste of herbs were mainly warm and bitter, respectively. We obtained 21 association rules and five new clusters. The Chuanxiong Rhizoma (Chuanxiong) and Angelica Sinensis Radix (Danggui) herb pair had the strongest correlation. Conclusion: We analyzed published CHM prescriptions for headaches with blood stasis syndrome and eliminated factors that did not reach an agreement, such as herb dosage. We used different data mining and analysis methods to ensure that the method and process were scientific and the conclusion was reliable, comprising a valuable reference for selecting herbs for the clinical treatment of headaches with blood stasis syndrome. The Xuefu Zhuyu Decoction (XFZYD) was the primary CHM prescription for headaches with blood stasis syndrome. Xiaoyao San (XYS) and Buyang Huanwu Decoction (BYHWD) might also be clinical references for treatment selection. Meridian-inducing and insect herbs might be used according to syndromes.
