The study explored the therapeutic effect and mechanism of the compound composed of tangerine peel,plum,agrimony and hawthorn on Eimeria tenella in chicks.In the experiment,144 chicks were divided into six groups:the blank group,the model group,the diclazuril group,and the high-dose,medium-dose and low-dose traditional Chinese medicine compound groups.The 14-day-old chickens were infected,the body weight and mortality were recorded,and the samples were dis-sected at 21 days of age.The anticoccidial effect of Chenpi compound at different doses was evalua-ted by calculating anticoccidial index,feed conversion rate and detecting serum cytokine levels and related mRNA expression levels.The results showed that the anticoccidial index of the middle dose group was 172.86,and the anticoccidial index of the low dose group was 158.98.In the middle and low dose groups,the levels of IL-1β,IL-6 and MDA in serum decreased significantly,while the levels of IL-4,IL10,T-AOC,SOD,CAT and GSH-Px increased significantly,and the mRNA ex-pression levels of related inflammation and antioxidant pathways changed.Further studies found that the medium-dose compound can regulate the ChTLR15/ChMyD88/ChNF-κB/ChNLRP3/Caspase-1 inflammatory signaling pathway,activate the Nrf2/Keap1/HO-1 antioxidant signaling pathway,and enhance the body's anti-inflammatory and antioxidant capacity;at the same time,it can increase the expression of intestinal tight junction ZO-1 and Occludin,repair the damaged in-testinal barrier,and play an anticoccidial role.The results showed that the middle dose of tangerine peel compound had a good effect in the treatment of coccidiosis,and its mechanism involved the regulation of anti-inflammatory and antioxidant pathways.

Objective:To investigate the differences and prognostic value of serum myeloid-related proteins 8 and 14 (Mrp 8/14) in patients with acute respiratory distress syndrome (ARDS) induced by pulmonary and extrapulmonary sepsis.Methods:A retrospective cohort study was conducted to collect the general clinical data of septic ARDS patients admitted to the intensive care unit (ICU) of Nanjing Hospital of Nanjing Medical University from August 2021 to February 2024. The serum levels of Mrp 8/14 were detected within 24 hours after admission. According to whether the patients died during ICU stay, the patients with pulmonary ARDS and extrapulmonary ARDS induced by sepsis were divided into survival and death groups, respectively. The differences of Mrp 8/14 and other clinical data between the two groups were compared. Logistic regression analysis was used to analyze the prognostic factors of septic patients with pulmonary ARDS and extrapulmonary ARDS. The receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of serum Mrp 8/14 for the prognosis of patients with pulmonary ARDS and extrapulmonary ARDS.Results:A total of 138 patients with sepsis-induced ARDS were enrolled in this study, including 79 patients with pulmonary ARDS and 59 patients with extrapulmonary ARDS. Compared to the death group, the level of serum Mrp 8/14 was significantly lower [Mrp 8/14: 22.90 (17.91, 30.88) μg/mL vs. 10.73 (7.15, 17.20) μg/mL, P<0.05]. Multivariate logistic regression analysis demonstrated that the serum Mrp 8/14 level was an independent risk factor for the prognosis of pulmonary ARDS patients only during the ICU stay ( OR=1.253, 95% CI: 1.110-1.414, P<0.05). ROC curve analysis showed that the area under the curve of serum Mrp 8/14 for the prediction of death in ARDS patients with pulmonary sepsis during ICU stay was 0.855 (95% CI: 0.773-0.938, P<0.05), the cut-off value was 19.230 μg/mL, the sensitivity was 0.718, the specificity was 0.925, and the Yonden index was 0.405. Conclusion:Serum Mrp 8/14 is an effective prognostic indicator for the mortality of ARDS patients with pulmonary sepsis during ICU hospitalization.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Objective:To evaluate the predictive value of the tricuspid annular plane systolic excursion to systolic pulmonary artery pressure ratio(TAPSE/sPAP) in identifying precapillary pulmonary hypertension(pcPH) patients requiring repeat balloon pulmonary angioplasty(BPA) within 3 months after initial intervention, and to determine independent risk factors associated with postoperative reintervention.Methods:We retrospectively collected clinical data from 215 consecutive patients with pcPH undergoing BPA. After applying exclusion criteria, 200 patients were ultimately included in the analysis. The predictive value of the TAPSE/sPAP for short-term BPA reintervention was assessed using receiver operating characteristic( ROC) curve analysis and multivariable logistic regression. Internal validation was performed through bootstrap resampling with 1 000 iterations to evaluate model stability. Results:A risk model for echocardiography was constructed using multiple logistic regression, and the results showed that systolic pulmonary artery pressure(sPAP), peak tricuspid regurgitation velocity(TRV), tricuspid regurgitation pressure gradient(PGTR), and TAPSE/sPAP ratio were predictive factors for BPA surgery in patients with pulmonary hypertension within 3 months. Multivariate regression analysis suggests that the TAPSE/sPAP ratio is an independent influencing factor for BPA after 3 months( OR=0.023, P<0.05). The predicted area under the ROC curve( AUC) for BPA after 3 months is 0.62(95% CI: 0.530-0.648), P<0.01, which is better than other cardiac ultrasound indicators. At the same time, internal bootstrap method was used for internal self-validation, and the AUC of the internal self-validation set was 0.67. Conclusion:The TAPSE/sPAP ratio serves as an independent predictor for requiring repeat BPA within 3 months postoperatively in patients with pcPH.

OBJECTIVES: To study the molecular mechanisms of LDH-loaded si-NEAT1 for regulating paclitaxel resistance and tumor-associated macrophage (TAM) polarization in breast cancer. METHODS: qRT-PCR and Western blotting were used to detect the expression of lncRNA NEAT1, miR-133b, and PD-L1 in breast cancer SKBR3 cells and paclitaxel-resistant SKBR3 cells (SKBR3-PR). The effects of transfection with si-NEAT1 and miR-133b mimics on MRP, MCRP and PD-L1 expressions and cell proliferation, migration and apoptosis were investigated using qRT-PCR, Western blotting, scratch and Transwell assays, and flow cytometry. Rescue experiments were conducted using si-NEAT1 and miR-133b inhibitor. Human THP-1 macrophages were cultured in the presence of conditioned media (CM) derived from SKBR3 and SKBR3-PR cells with or with si-NEAT1 transfection for comparison of IL-4-induced macrophage polarization by detecting the surface markers. LDH@si-NEAT1 nanocarriers were constructed, and their effects on MRP, MCRP and PD-L1 expressions and cell behaviors of the tumor cells were examined. THP-1 cells were treated with the CM from LDH@si-NEAT1-treated tumor cells, and the changes in their polarization were assessed. RESULTS: SKBR3-PR cells showered significantly upregulated NEAT1 and PD-L1 expressions and lowered miR-133b expression as compared with their parental cells. Transfection with si-NEAT1 and miR-133b mimics inhibited viability, promoted apoptosis and enhanced MRP and BCRP expressions in SKBR3-PR cells. NEAT1 knockdown obvious upregulated miR-133b and downregulated PD-L1, MRP and BCRP expressions. The CM from SKBR3-PR cells obviously promoted M2 polarization of THP-1 macrophages, which was significantly inhibited by CM from si-NEAT1-transfected cells. Treatment with LDH@si-NEAT1 effectively inhibited migration and invasion, promoted apoptosis, and reduced MRP, BCRP and PD-L1 expressions in the tumor cells. The CM from LDH@si-NEAT1-treated SKBR3-PR cells significantly downregulated Arg-1, CD163, IL-10, and PD-L1 and upregulated miR-133b expression in THP-1 macrophages. CONCLUSIONS LDH@si-NEAT1 reduces paclitaxel resistance of breast cancer cells and inhibits TAM polarization by targeting the miR-133b/PD-L1 axis.
