Non-alcoholic fatty liver disease （NAFLD） is a chronic liver disease closely related to metabolism， which is mainly characterized by abnormal lipid deposition in hepatocytes. In recent years， with the increasing prevalence of obesity and metabolic syndrome， NAFLD has become one of the most common chronic diseases in the world. The pathogenesis of NAFLD is complex and varied， involving the cross-regulation of multiple signaling pathways such as glucose-lipid metabolism， oxidative stress， and inflammation. The TLR4 signaling pathway plays a key role in the development and progression of NAFLD， and abnormal activation of this pathway accelerates the deterioration of NAFLD by promoting the release of pro-inflammatory cytokines， inducing oxidative stress， and exacerbating insulin resistance. Studies have shown that traditional Chinese medicine （TCM） can regulate the TLR4 signaling pathway to alleviate the symptoms and pathological features of NAFLD. The present review summarizes the experimental research progress in the TCM regulation of the TLR4 signaling pathway in treating NAFLD in the past 5 years， covering a wide range of TCM active ingredients （such as polysaccharides， terpenoids， alkaloids， flavonoids） and compound prescriptions. The active ingredients and compound prescriptions of TCM can effectively ameliorate lipid metabolism disorders， reduce insulin resistance， regulate intestinal flora， and inhibit inflammation and oxidative stress by regulating the TLR4 signaling pathway via multiple targets and pathways， thus slowing down the progression of NAFLD. Through in-depth analysis of the pathological mechanisms of NAFLD and exploration of the potential of TLR4 signaling pathway as a therapeutic target， we can provide theoretical support for the application of TCM in the treatment of NAFLD， as well as new perspectives and directions for future clinical research and new drug development， thereby promoting the innovation and development of therapeutic strategies for NAFLD.

Transcranial electrical stimulation (tES) is a non-invasive neural modulation technique known for its high safety, patient compliance, and portability. It holds promise as a potential non-pharmacological method for analgesia. However, challenges persist in utilizing tES for pain management, including inconsistent research findings and limited understanding of its analgesic mechanisms. Therefore, by summarizing the advances in the analgesic researches employing the 3 primary tES techniques, transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), and transcranial random noise stimulation (tRNS), we reviewed the analgesic effects on both acute and chronic pain, as well as the neural mechanisms underlying the analgesic effect of each technique. Accumulating evidence suggests that the analgesic effects of tDCS are significant, but studies on analgesic effects of tACS and tRNS remain limited. And the exact mechanisms of pain relief through tES turned out to be not yet well established. Furthermore, we systematically discussed the limitations of analgesia-related studies employing tES techniques across various aspects, involving research design, stimulation protocol formulation, neural response observation, analgesic effect assessment, and safety considerations. To address these limitations and advance clinical translation, we emphasized utilizing promising stimulation techniques and offered practical suggestions for future research endeavors. Specifically, employing numerical simulation of electric field guided by magnetic resonance imaging (MRI) would reduce variability of outcomes due to individual differences in head anatomy. For this purpose, it is advisable to establish standardized head models based on MRI data from the Chinese populations and validate simulated electric field results in tES research to diminish confounding factors concerning anatomy. Meanwhile, novel techniques like multi-site brain stimulation and interferential stimulation (IFS) could broaden the range of stimulation sites in both scope and depth. Multi-site brain stimulation facilitates modulation of entire neural networks, enabling more sophisticated investigations into the complexity of pain. IFS can reach deep brain tissues without invasive surgical procedures, achieving more comprehensive modulation. Regarding neural response observations, establishing a tES-neuroimaging synchronized platform would enable revealing its mechanisms and personalizing protocols based on inter-subject neural response variability detected through recordings. By integrating tES with various neuroimaging techniques, such as functional MRI, electroencephalography (EEG) and magnetoencephalography, into one unified platform, researchers could examine brain activities in baseline before stimulation, dynamic changes in brain activities during stimulation, and sustained brain responses after stimulation. Additionally, collecting finer-grained data on participant characteristics and pain intensity would enhance the sensitivity of future studies. In designing clinical trials to evaluate chronic pain treatments and reporting the results, adopting the six core outcome domain measures recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) could prove beneficial. Lastly, safety considerations can never be overemphasized in future tES studies especially when combining tES with MRI and EEG techniques. These efforts may help to broaden the research scope, reconcile inconsistencies in findings and elucidate the analgesic mechanisms of tES, thus facilitating the development of pragmatic pain management strategies such as combination therapies and home therapies. Ultimately, these suggestions will maximize the clinical application value of tES in pain treatment to achieve pain relief for patients.

Acute liver injury (ALI) is one of the common severe diseases in clinic, which is characterized by redox imbalance and inflammatory storm. Untimely treatment can easily lead to liver failure and even death. Rosmarinic acid (RA) has been proved to have anti-inflammatory and antioxidant activity, but it is not clear how to protect ALI through antioxidation and inhibition of inflammation. Therefore, this study explored the therapeutic effect and molecular mechanism of RA on ALI through in vitro and in vivo experiments. In the mouse ALI model, the effects of RA on liver function and inflammatory indexes were studied, the pathological changes of liver were observed by HE, the effect of RA on reactive oxygen species in liver was detected by fluorescence method, and the level of F4/80 in liver tissue was detected by immunohistochemical method. The levels of thioredoxin interacting protein (TXNIP), NOD-like receptor protein 3 (NLRP3) and cysteinyl aspartate specific proteinase-1 (CASPASE-1) in liver tissue were measured by Western blot. All animal welfare and experimental procedures follow the rules of the Animal Ethics Committee of Southwest Minzu University. In vitro, human hepatoma cell line HepG2 was used to establish the model of oxidative damage induced by H₂O₂. The cell viability was detected by CCK-8 method. The level of interleukin-1β (IL-1β) in the supernatant was detected by enzyme linked immunosorbent assay (ELISA), the activity of lactatede hydrogenase (LDH) was detected by LDH kit, and the level of ROS was detected by fluorescence probe DCFH-DA labeling. The mRNA expression of Txnip, Nlrp3, Caspase 1, Il1β was detected by real-time fluorescence quantitative PCR (qPCR), and the protein levels of nuclear factor erythroid-2 related factor 2 (NRF2), TXNIP, NLRP3 and CASPASE-1 were measured by Western blot. The results showed that compared with the model group, the degree of liver swelling, tissue injury, liver function index in RA group were significantly lower than those in model group. And RA significantly attenuated the increases of ROS in liver tissue. The expression levels of TXNIP, NLRP3 and CASPASE-1 in liver tissue were significantly lower than those in model group. Additionally, RA inhibited the expressions of F4/80 and IL-1β. In vitro experiment, compared with model group, RA effectively inhibited the secretion of IL-1β and LDH. The level of ROS also decreased significantly. RA inhibited the mRNA expressions of Txnip, Caspase 1, Il1β. Furthermore, RA significantly increased the expression level of NRF2 protein in nucleus, and decreased the expression level of TXNIP and NLRP3 protein. Specifically, with the addition of ML385, the effect of RA on NRF2, TXNIP, NLRP3, CASPASE-1 protein expression was reversed. Collectively, these findings suggested that RA may inhibit the production of ROS by promoting NRF2 nuclear transfer, and then reduce the activation of NLRP3 inflammatory bodies by TXNIP, reduce cell death and inflammatory response to prevent the liver injury.

Objective:To analyze the effects of preoperative renin-angiotensin system inhibitor (RASi) use on postoperative renal function and short-term and long-term prognosis in patients undergoing coronary artery bypass grafting (CABG).Methods:A retrospective cohort analysis was conducted. Based on the registration study data of CABG patients at Fuwai Hospital, Chinese Academy of Medical Sciences, the clinical data of adult patients who underwent CABG from January 2013 to December 2022 were analyzed. Preoperative use of RASi (PreRASi) was defined as receiving RASi treatment within 48 hours before surgery. Postoperative acute kidney injury (AKI) was defined using the diagnostic criteria of Kidney Disease: Improving Global Outcomes (KDIGO). Demographic characteristics, past medical history, comorbidities, preoperative medication, preoperative laboratory test results, specific information on surgical procedures, and postoperative treatment related data were extracted. The primary endpoint was the incidence of postoperative AKI. Secondary endpoints included in-hospital all-cause mortality and all-cause mortality within the longest follow-up period. According to whether RASi was used before surgery, the patients were divided into PreRASi group and No-PreRASi group. The baseline data of the two groups were balanced by propensity score matching (PSM). Logistic regression model and Cox proportional hazards model were used to assess the correlation between PreRASi and postoperative AKI and clinical outcomes, and analyze the subgroups of hypertension and heart failure with preserved ejection fraction (HFpEF) in the cohort.Results:A total of 33?884 patients who underwent CABG were included, with a mean follow-up duration of (3.0±2.4) years and the longest follow-up duration up to 8.5 years. There were 9?128 cases (26.94%) in the PreRASi group and 24?756 cases (73.06%) in the No-PreRASi group. The incidence of postoperative AKI in the PreRASi group was 47.61% (4?346 cases), compared to 52.37% (12?964 cases) in the No-PreRASi group. Two groups were matched with 5?094 patients each. Compared to the No-PreRASi group, both before and after PSM, PreRASi was associated with a reduction of risk of postoperative AKI [before PSM: odds ratio ( OR) = 0.834, 95% confidence interval (95% CI) was 0.793-0.877, P < 0.001; after PSM: OR = 0.875, 95% CI was 0.808-0.948, P = 0.001]. Subgroup analysis of hypertensive and HFpEF patients showed that PreRASi was associated with a decreased risk of postoperative AKI before and after PSM. The in-hospital mortality for the PreRASi and No-PreRASi groups were 0.61% (56 cases) and 0.49% (121 cases), respectively. Analysis of the overall cohort and subgroups with hypertension and HFpEF showed no correlation between PreRASi and in-hospital mortality or longest follow-up mortality. Conclusion:The perioperative use of RASi can reduce the risk of postoperative AKI in patients undergoing CABG, has a certain renal protective effect, but is not associated with short-term or long-term death risk after surgery.

Natural products are an important source for the development of antitumor lead compounds, but the pharmacological effects and regulatory mechanisms of natural products in osimertinib resistance in non-small cell lung cancer (NSCLC) are not well understood. The natural product ligustroflavone was used as the research object to analyze its efficacy in osimertinib-resistant NSCLC cells by cell proliferation assay and cell cycle detection. The potential targets of ligustroflavone in osimertinib-resistant NSCLC cells were screened by public databases and bioinformatics, molecular docking and microscale thermophoresis were used to identify the interaction between privet and target molecules. Western blot was used to detect the effect of privet on the target molecules and their downstream pathways. Ligustroflavone reduced the proliferation of osimertinib-resistant NSCLC cells, and could arrest the cell cycle. Cyclin-dependent kinase 6 (CDK6) was the potential target of ligustroflavone in osimertinib-resistant NSCLC cells. Ligustroflavone inhibited the activation of CDK6-Rb axis. Together, ligustroflavone could regulate osimertinib resistance in NSCLC cells by binding cell cyclin-related molecules. This study provides a theoretical basis for the targeted drug resistance of NSCLC with natural products, and also provides a new idea for the development of clinical drug combination.
