Local anesthetics (LAs), such as articaine (AT), exhibit limited efficacy in inflammatory environments, which constitutes a significant limitation in their clinical application within oral medicine. In our prior research, we developed AT-17, which demonstrated effective properties in chronic inflammatory conditions and appears to function as a novel oral LA that could address this challenge. In the present study, we further elucidated the beneficial effects of AT-17 in acute inflammation, particularly in oral acute inflammation, where mitochondrial-related apoptosis played a crucial role. Our findings indicated that AT-17 effectively inhibited lipopolysaccharide (LPS)-induced nerve cell apoptosis by ameliorating mitochondrial dysfunction in vitro. This process involved the inhibition of mitochondrial reactive oxygen species (mtROS) production and the subsequent activation of the NRF2 pathway. Most notably, improvements in mitochondria-related apoptosis were key contributors to AT-17's inhibition of voltage-gated sodium channels. Additionally, AT-17 was shown to reduce mtROS production in nerve cells through the Na+/NCLX/ETC signaling axis. In conclusion, we have developed a novel local anesthetic that exhibits pronounced anesthetic functionality under inflammatory conditions by enhancing mitochondria-related apoptosis. This advancement holds considerable promise for future drug development and deepening our understanding of the underlying mechanisms of action.

Objective:To investigate the factors influencing the prognosis of critically ill patients and the predictive value of the C-reactive protein-albumin-lymphocyte (CALLY) index.Methods:A retrospective analysis was conducted on the clinical data of 122 critically ill patients admitted to Guoyao Dongfeng General Hospital affiliated with Hubei University of Medicine from June 2022 to December 2023. Patients were divided into a death group and a survival group based on their 28-day prognosis. Clinical data were compared between the two groups to analyze the factors influencing prognosis and assess the predictive value of various indicators. Normally distributed measurement data were expressed as Mean±SD, and intergroup comparisons were performed by independent samples t-test; non-normally distributed measurement data were expressed as M( Q1,Q3), and intergroup comparisons were performed by the Mann-Whitney U test. Counting data were expressed as case (%), and intergroup comparisons were performed by the χ2 test. Multivariate logistic regression was used to analyze factors influencing patient prognosis, and receiver operating characteristic (ROC) curves were plotted to analyze the predictive value of each indicator. Results:The Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, blood lactate, CRP, and B-type natriuretic peptide levels in the death group were higher than those in the survival group [22 (17, 30) points vs. 17 (14, 22) points, (4.8±1.4) mmol/L vs. (3.3±1.0) mmol/L, 134 (83, 2 381) mg/L vs. 13 (10, 27) mg/L, 259 (111, 592) ng/L vs. 108 (40, 247) ng/L; Z=3.04, P=0.002; t=5.79, P<0.001; Z=8.57, P<0.001; Z=3.28, P=0.001, respectively]. Albumin, neutrophil count, lymphocyte count (LYC), and the CALLY index were lower in the death group than in the survival group [(31±5) g/L vs. (37±6) g/L, (58±9)×10 9/L vs. (63±10)×10 9/L, 0.6 (0.4, 0.8)×10 9/L vs. 1.3 (0.8, 1.7)×10 9/L, 0.03 (0.02, 0.11) vs. 0.26 (0.13, 0.49); t=6.05, P<0.001; t=3.04, P=0.003; Z=5.82, P<0.001; Z=6.52, P<0.001, respectively]. Multivariate logistic regression analysis indicated that the APACHE Ⅱ score and CRP were risk factors for poor prognosis in critically ill patients ( OR=1.349, 95% CI: 1.004-1.821, P=0.048; OR=1.006, 95% CI: 1.003-1.010, P=0.001, respectively), while LYC and the CALLY index were protective factors ( OR=0.297, 95% CI: 0.111-0.795, P=0.016; OR=0.989, 95% CI: 0.955-0.999, P=0.001, respectively). The area under the ROC curve for the CALLY index predicting 28-day mortality in critically ill patients was 0.872 (95% CI: 0.800-0.926), which was higher than that of the APACHE Ⅱ score, LYC, and CRP [0.673 (95% CI: 0.582-0.756), 0.664 (95% CI: 0.573-0.748), 0.576 (95% CI: 0.482-0.665), respectively]. The cut-off values were 0.06, 20 points, 0.8×10 9/L, and 50 mg/L, respectively. When the CALLY index was 0.06, the specificity was 97.65%, the sensitivity was 72.97%, and the Youden index was 0.706. Conclusions:The APACHE Ⅱ score, CRP, LYC, and CALLY index are all factors influencing the prognosis of critically ill patients. The CALLY index has certain predictive value, but its false negative rate is relatively high. Further combination with other indicators is needed to improve its predictive value.

Objective To compare the differences in lipid metabolism between platinum-resistant and platinum-sensitive ovarian cancer patients at stage Ⅲ-Ⅳ,to analyze the differential intestinal flora using 16S rRNA sequen-cing,and to explore the associations among intestinal flora,lipid metabolism characteristics and platinum resistance in ovarian cancer.Methods Patients diagnosed with ovarian cancer at stage Ⅲ-Ⅳ through surgical pathology were selected,including a platinum-resistant group(11 cases)and a platinum-sensitive group(11 cases).The differences in lipid metabolism between the two groups were compared.The differences in gut microbiota between the two groups were investigated using fecal 16S rRNA sequencing.The association among gut microbiota,lipid metabolism characteristics,and platinum resistance in ovarian cancer was analyzed.Results Significant differ-ences were observed in lipid metabolism-related indicators[total cholesterol(TC),high-density lipoprotein choles-terol(HDL-C),non-high-density lipoprotein cholesterol(n-HDL),low-density lipoprotein cholesterol(LDL-C),apolipoprotein(B)]between the two groups,with higher levels in the platinum-resistant group.The Shannon in-dex(P=0.008 3)and Simpson index(P=0.008 2)both showed higher diversity of gut microbiota in platinum-resistant ovarian cancer patients compared to the platinum-sensitive group.However,based on OTUs species clus-tering and relative abundance statistics,certain bacterial abundances differed significantly between the groups.Spe-cies such as Parabacteroides,Akkermansia,Blautia,Lachnoclostridium,Fusicatenibacter,and Megamonas had sig-nificantly higher abundances in the platinum-sensitive ovarian cancer group,and Akkermansia(a lipid metabolism-related bacterial group)was the most prevalent.Conclusion The platinum-resistant group of ovarian cancer ex-hibits significantly higher levels of lipid metabolism and gut microbiota diversity compared to the platinum-sensitive group.This suggests that the increase in lipid metabolism levels and fecal microbiota diversity may be associated with the development of platinum resistance.However,certain microbial taxa are reduced in abundance in the plat-inum-resistant group,such as the distinct Akkermansia genus(a lipid metabolism-related microbial community),which may serve as one of the factors inducing platinum-resistance in ovarian cancer.
