With the widespread use of antimicrobial agents, bacterial drug resistance has become an increasingly severe issue, posing significant challenges to global healthcare. Traditional Chinese medicine (TCM) has emerged as a research focus in the field of bacterial resistance due to its broad sources, high safety profile, low toxicity, and antimicrobial mechanisms distinct from those of chemical drugs. Studies have shown that various TCM herbs, such as Scutellaria baicalensis, exert antibacterial effects through multiple pathways, including disrupting the integrity of bacterial cell walls and membranes, inhibiting nucleic acid and protein synthesis, and impairing energy production and metabolism. Additionally, certain TCM herbs, including Scutellaria baicalensis, Coptis chinensis, and Fritillaria thunbergii, can reverse antimicrobial resistance by eliminating resistant plasmids, inhibiting bacterial efflux pump function, and suppressing β-lactamase activity. TCM holds promising potential for antibacterial applications and synergistically reversing antimicrobial resistance, though systematic analyses remain limited. This review summarizes the mechanisms of antibacterial action of TCM and current research on its synergistic use with antimicrobial agents to reverse drug resistance, aiming to provide insights for developing novel TCM-based antimicrobials and addressing bacterial resistance.

Objective:To investigate the influencing factors of falls in patients with chemotherapy-induced peripheral neuropathy for gynecological cancer, and establish a Nomogram model based on independent influencing factors.Methods:A total of 216 patients with peripheral neuropathy who received chemotherapy for gynecological cancer in The First Affiliated Hospital of Army Military Medical University of the People′s Liberation Army from February 2021 to April 2023 were retrospectively selected, and were divided into the modeling set and the validation set according to the ratio of 7∶3 using random number table method. According to the occurrence of falls in the modeling set, the patients were divided into the fall group and the non-fall group. Independent influencing factors were obtained through univariate analysis and multivariate Logistic regression analysis, and a prediction model was constructed based on the regression analysis. A Nomogram map was drawn using R language software. Receiver operating characteristic curve (ROC) and calibration curve were used to test the prediction efficiency, and the predictive benefits were evaluated by clinical decision curve.Results:Among the 216 patients, 151 were included in the modeling set and 65 in the validation set. Among the patients in the modeling set, 53 cases were in the fall group, aged (62.89 ± 8.58) years old, and 98 cases were in the non-fall group, aged (59.48 ± 8.12) years old. Chemotherapy cycle, Neuropathy Impairment Score-Lower Limbs, Barthel index, Home Falls and Accidents Screening Tool, regular exercise habits, diabetes and depression were all independent influencing factors for falls in patients with chemotherapy-induced peripheral neuropathy of gynecologic cancer ( OR values were 0.312-3.727, all P<0.05). The area under the curve (AUC) of the established Nomogram model was 0.873, with good discriminating ability. The mean absolute error (MAE) of calibration curve was 0.048, which fitted the ideal curve, indicating that the model has good calibration performance. The AUC of the validation set was 0.873 and the MAE of calibration curve was 0.073, indicating that the model has good external prediction efficiency. Conclusions:This Nomogram model can predict falls in patients with chemotherapy-induced peripheral neuropathy of gynecological cancer and provide evidence for clinical prevention of falls.

During the process of dairy farming,various factors such as physical injury and bacterial infection act upon body tissues or organs,leading to the disruption of skin or mucous tissue integ-rity and subsequent tissue injury and trauma.The healing of these injuries is a complex process that necessitates the coordinated efforts of different cells and involvement of diverse cytokines.A-mong them,the interaction between macrophages and myofibroblasts is indispensable for efficient tissue repair.Nod-like receptor protein 3(NLRP3),a pattern recognition receptor in the innate im-mune system,may play a regulatory role in modulating this intricate process.In this study,cow myofibroblasts and M1 type bone marrow-derived macrophages were cultured in vitro,followed by collection of cell culture supernatant for co-culture analysis.Both cytokine secretion levels in M1 type bone marrow-derived macrophages as well as expression patterns levels of myofibroblast growth factor protein and mRNA were detected.The regulatory mechanism underlying NLRP3 in-volvement in mediating interactions between these two cell types was investigated using NLRP3 inhibitor MCC950.The results showed that an effective method for culturing cow muscle fibroblasts in vitro was successfully established and myofibroblast conditioned medium(MFbCM)could regulate M1 macrophage secretion profiles.Moreover,M1 macrophage conditioned medium(M1?CM)was found to influence myofibroblast growth factor expression levels.Our findings sug-gest that NLRP3 plays a significant regulatory role during crosstalk between myofibroblasts and M1-type pro-inflammatory macrophages.

Objective:To investigate the predictive value of preoperative lymphocyte-to-monocyte ratio (LMR) combined with platelet-to-lymphocyte ratio (PLR) (LMR-PLR) scoring model for prognosis of pancreatic ductal adenocarcinoma (PDAC) after radical resection.Methods:The retrospective cohort study was conducted. The clinicopathological data of 116 patients with PDAC who were admitted to the Second Hospital of Lanzhou University from January 2015 to December 2019 were collected. There were 73 males and 43 females, aged 61.5(range, 29.0-75.0)years. All patients underwent radical resection for PDAC. Observation indicators: (1) optimal cut-off value of LMR and PLR; (2) clinicopathological features of patients with different scores of preoperative LMR-PLR scoring model; (3) follow-up and survival; (4) influencing factors for prognosis of PDAC patients; (5) construction and verification of nomogram prediction model. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Mann-Whitney U test. The Graphpad prism 8 was used to draw survival curve, the Kaplan-Meier method was used to calculate survival rate, and the Log-Rank test was used for survival analysis. The COX proportional hazard regression model was used for univariate and multivariate analyses. The X-tile software was used to determine the optimal cut-off values of LMR and PLR. The nomogram prediction model was conducted based on the results of multivariate analysis, and the receiver operating characteristic (ROC) curve was drawn. The area under curve (AUC) was used to evaluate the discrimination of nomogram prediction model. The calibration curve was used to evaluate the consistency of nomogram prediction model and the decision curve was used to evaluate the clinical benefits. Results:(1) Optimal cut-off value of LMR and PLR. The optimal cut-off values of LMR and PLR were 1.9 and 156.3. (2) Clinicopathological features of patients with different scores of preoperative LMR-PLR scoring model. Cases with LMR-PLR scoring as 0, 1, 2 were 11, 42, 63. Cases with CA125 <12.4 U/mL, cases postoperative with vascular invasion, cases with postoperative chemotherapy in patients with 0, 1, 2 of LMR-PLR scoring were 1, 8, 24, 9, 27, 27, 3, 26, 43, showing significant differences among them ( χ2=6.73, 8.37, 6.68, P<0.05). (3) Follow-up and survival. All 116 patients were followed up for 39(range, 2-86)months. The 1-, 2-, 3-year survival rate of 116 PDAC patients was 50.9%, 37.9%, 19.3%, respectively, with a survival time of 13(range, 1-85)months. The survival time of patients with LMR-PLR scoring as 0, 1, 2 was 3(range, 1-9)months, 7(range, 2-56)months, 26(range, 2-85)months, respectively, showing a significant difference among them ( χ2=48.78, P<0.05). (4) Influencing factors for prognosis of PDAC patients. Results of multivariate analysis showed that carcinoembryonic antigen (CEA), CA19-9, LMR-PLR score, tumor diameter were independent factors affecting prognosis of patients ( hazard ratio=1.61, 1.88, 0.27, 1.87, 95% confidence interval as 1.02-2.54, 1.18-3.00, 0.19-0.39, 1.13-3.09, P<0.05). (5) Construction and verification of nomogram prediction model. The nomogram prediction model was constructed based on CEA, CA19-9, LMR-PLR score and tumor diameter. The AUC of ROC curve in predicting 1-, 2-, 3-year survival rate of patients was 0.86 (95% confidence interval as 0.79-0.93, P<0.05), 0.86 (95% confidence interval as 0.79-0.92, P<0.05), 0.87 (95% confidence interval as 0.78-0.95, P<0.05), respectively. Results of calibration curve showed that the predicted survival rate of nomogram prediction model was consistent with the actual survival rate, with the consistency index as 0.74. Results of decision curve showed that the predictive performance of nomogram prediction model was superior to that of a single factor at a risk threshold of 0.12-0.85. Conclusions:CEA, CA19-9, LMR-PLR score, tumor diameter are independent factors affecting prognosis of patients undergoing radical resection for PDAC, and the nomogram prediction model can predict postoperative survival rate. The predicted survival rate of nomogram prediction model is consistent with the actual survival rate, and the predictive performance of nomogram prediction model is superior to that of a single factor at a risk threshold of 0.12-0.85.

Objective To investigate the predictive value of preoperative fibrinogen/albumin ratio (FAR) and systemic immune inflammation index (SII) on the postoperative prognosis of patients with pancreatic ductal adenocarcinoma. Methods An ROC curve was used in determining the best cutoff values of FAR and SII and then grouped. The Cox proportional hazards model was used in analyzing the prognostic factors of radical pancreatic cancer surgery, and then a Nomogram prognostic model was established. C-index, AUC, and calibration curve were used in evaluating the discrimination and calibration ability of the Nomogram. DCA curves were used in assessing the clinical validity of the Nomograms. Results The optimal cutoff values for preoperative FAR and SII were 0.095 and 532.945, respectively. FAR≥ 0.095, SII≥ 532.945, CA199≥ 450.9 U/ml, maximum tumor diameter≥ 4 cm, and the absence of postoperative chemotherapy were independent risk factors for the poor prognosis of pancreatic cancer (
