The inflammatory microenvironment is closely associated with the initiation and progression of osteoarthritis (OA), specifically manifesting as macrophage activation, dysregulation of inflammatory cytokines, and redox imbalance. Following an overview of the pathological characteristics of the OA inflammatory microenvironment, this paper reviews the research progress on the mechanism of traditional Chinese medicine (TCM) intervening in OA by modulating the inflammatory microenvironment. It has been found that TCM monomers/active ingredients (such as total alkaloids from Strychnos nux-vomica , quercetin, triptolide, etc.), herb pairs (e.g. Angelica pubescens - Gentiana macrophylla , Carthami Flos-Lycopodii Herba), and TCM formulas (such as Zhuanggu jianxi formula, Duhuo jisheng decoction and Rongjin niantong formula, etc.) can inhibit macrophage activation, reduce the release of proinflammatory cytokines and the generation of reactive oxygen species by inhibiting multiple signaling pathways, including nuclear factor-κB, Wnt/ β -catenin, and mitogen-activated protein kinase, thereby alleviating the articular inflammatory microenvironment, restoring local joint homeostasis, and slowing the progression of OA.

ObjectiveThe malaria parasites remodel the host erythrocyte structure by exporting parasite proteins that interact with the membrane skeleton proteins of red blood cells (RBCs), facilitating their intracellular survival and pathogenicity. Skeleton-binding protein 1 (SBP1) is a conserved exported protein across Plasmodium species. In Plasmodium falciparum, SBP1 has been reported to interact with erythrocyte membrane skeleton proteins 4.1R and spectrin, while its contribution to erythrocyte remodeling and parasite virulence in Plasmodium berghei (Pb) remains unclear. This study aims to determine whether PbSBP1 associates with the host cytoskeletal protein 4.1R and to investigate its role in the remodeling of host RBCs and the pathogenicity of Plasmodium berghei. MethodsIn Plasmodium berghei, the relationship between PbSBP1 and the erythrocyte cytoskeletal protein 4.1R was examined using co-immunoprecipitation. A Pbsbp1 gene knockout mutant of Plasmodium berghei (Pbsbp1∆) was generated based on the principle of double crossover homologous recombination. The deformability of erythrocytes infected with Pbsbp1∆ parasites was assessed using microfluidic methods. Microchannels with an array of cylindrical pillars were used to detect modifications in infected RBC deformability. The infected RBCs were squashed between the rows and recovered between the columns and the transit velocity (μm/s) of infected RBCs travelling through the microchannel was recorded. The component of the erythrocyte membrane skeleton junctional complex, tropomodulin (TMOD), was fluorescently labeled, and the cytoskeletal network of infected erythrocytes was imaged using super-resolution stochastic optical reconstruction microscopy (STORM) to analyze ultrastructural changes in the cytoskeleton of wild-type (WT) and Pbsbp1∆-infected erythrocytes. Actin-based junctional complexes were displayed as individual clusters by the labeled TMOD in the STORM images, and the cluster densities and distances between adjacent clusters of infected RBCs were calculated. Additionally, rodent malaria models (BALB/c mice) and experimental cerebral malaria models (C57BL/6 mice) were employed to monitor the growth of Pbsbp1∆ and WT parasites during the intraerythrocytic stage and their capacity to induce cerebral malaria in mice. ResultsPbSBP1 may participate in the remodeling of infected erythrocytes through direct or indirect interaction with the erythrocyte cytoskeletal protein 4.1R. Microfluidic assays revealed that the deformability of erythrocytes infected with Pbsbp1∆ parasites was significantly enhanced compared to those infected with WT parasites. STORM imaging further demonstrated that the ultrastructure of the erythrocyte cytoskeleton in Pbsbp1∆-infected cells was altered relative to that in WT-infected erythrocytes. The distances between nearest neighbors of clusters had a tendency to increase while the cluster densities were decreased in Pbsbp1∆-infected RBCs compared to WT-infected RBCs. Subsequent phenotypic analysis indicated that the growth rate of Pbsbp1∆ parasites during the intraerythrocytic stage was significantly slower than that of WT parasites, and their ability to induce cerebral malaria in mice was also attenuated. These findings suggest that PbSBP1 is involved in the remodeling of the erythrocyte membrane skeleton, likely through its direct or indirect interaction with protein 4.1R, thereby regulating the deformability of infected erythrocytes and influencing the pathogenicity of the blood-stage parasites. ConclusionThis study establishes a role for PbSBP1 in host erythrocyte remodeling and parasite virulence, providing new research strategies for the prevention and treatment of malaria.

This study explored the effects and underlying mechanism of Raf kinase inhibitory protein(RKIP)on apoptosis in mast cells sensitized by Echinococcus granulosus cyst fluid.Bone marrow-derived mast cells(BMMCs)were isolated and cultured from RKIP knockout(KO)and wild-type(WT)C57BL/6 mice.Cells were divided into control and sensitized groups.The sensitized group was incubated for 24 h in RPMI1640 medium containing 10%serum from mice infected with E.granulosus,then activated for 3 h or 6 h with E.granulosus cyst fluid.The control group was incubated for 24 h in RPMI1640 medium,and then received an equal vol-ume of PBS.Cells and supernatants were collected for analysis.Flow cytometry was used to detect the expression of CD117 and FcεRⅠα on BMMCs.The levels of β-hexosaminidase,IL-4,and TNF-α in the supernatant were quantified with ELISA.Western blot analy-sis was used to assess expression changes in RKIP,apoptosis-related proteins,and pathway proteins in BMMC before and after sensi-tization.Flow cytometry analysis revealed that after 4 weeks of induction,the CD117 and FcεRⅠα double-positivity rates on both WT and KO BMMC exceeded 90%.ELISA indicated that the E.granulosus cyst fluid resulted in significantly greater β-hexosaminidase re-lease(F=16.88,P<0.05),and levels of IL-4(F=16.51,P<0.05)and TNF-α(F=9.78,P<0.05)in the KO sensitized group than the WT sensitized group.With respect to the WT control group,the WT sensitized group showed significantly down-regulated pro-tein expression levels of RKIP(F=8.20,P<0.05)and Bcl-2(F=101.40,P<0.01)after 3 h,but significantly up-regulated levels of p-PI3K(F=8.04,P<0.05),p-Akt(F=32.52,P<0.01),p-P65(F=13.29,P<0.05),and cleaved-caspase-3(F=46.34,P<0.01).With respect to the WT sensitized group,the KO sensitized group showed significantly up-regulated protein expression of p-PI3K(F=8.45,P<0.05),p-Akt(F=8.58,P<0.05),p-P65(F=11.02,P<0.05),and Bcl-2(F=84.50,P<0.001)after 3 h,but significantly down-regulated expression of cleaved-caspase-3(F=15.66,P<0.05).In conclusion,RKIP may inhibit the PI3K/Akt/NF-κB pathway,thereby inducing apoptosis in mast cells sensitized by E.granulosus cyst fluid.This process may help ease aller-gic reactions caused by mast cells in echinococcosis,thus offering a promising new approach for preventing and treating such reactions.

Objective:To explore the influencing factors of brain injury in children with neonatal asphyxia after resuscitation.Methods:The clinical data of 180 children with neonatal asphyxia from January 2017 to January 2024 in Shijiazhuang Maternal and Child Health Hospital were retrospectively analyzed, and all children were received resuscitation treatment. The children were divided into modeling group (126 cases) and validation group (54 cases) in a 7∶3 ratio. Among the children in modeling group, 51 children combined brain injury (brain injury subgroup), and 75 children did not combine brain injury (non-brain injury subgroup). The general data were recorded, and the continuous variables were determined by the receiver operating characteristic (ROC) curve to determine the optimal cut-off value. Multivariate Logistic regression analysis was used to analyze the independent risk factors of brain injury in children with neonatal asphyxia after resuscitation. The R language software "rms" package was used to construct a nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation. The nomogram model was internally verified by the calibration curve, and the prediction efficiency of the nomogram model was evaluated by the decision curve and ROC curve.Results:There was no statistical difference in general data between modeling group and validation group ( P>0.05). The gestation age<37 weeks proportion, severe asphyxia proportion, Ⅱ to Ⅲ grade amniotic fluid contamination proportion, intrauterine distress proportion and blood lactate in brain injury subgroup were significantly higher than those in non-brain injury subgroup: 60.78% (31/51) vs. 38.67% (29/75), 37.25% (19/51) vs. 17.33% (13/75), 27.45% (14/51) vs. 10.67% (8/75), 47.06% (24/51) vs. 26.67% (20/75) and (2.64 ± 0.61) mmol/L vs. (2.21 ± 0.56) mmol/L, and there were statistical differences ( P<0.05 or <0.01); there were no statistical differences in gender composition, birth weight, maternal age, maternal history of adverse pregnancy and childbirth, mode of delivery, parity, abnormal amniotic fluid volume, abnormal fetal position, abnormal umbilical cord, abnormal placenta, systolic blood pressure, diastolic blood pressure, body temperature and blood glucose between the two groups ( P>0.05). ROC curve analysis result showed that the optimal cutoff value of blood lactate was 2.59 mmol/L. Multivariate Logistic regression analysis result showed that the young gestation age, severe asphyxia, Ⅱ to Ⅲ grade amniotic fluid contamination, intrauterine distress and high blood lactate were independent risk factors of brain injury in children with neonatal asphyxia after resuscitation ( OR = 2.854, 3.428, 3.405, 3.427 and 7.844; 95% CI 1.166 to 6.983, 1.263 to 9.305, 1.076 to 10.768, 1.358 to 8.645 and 3.080 to 19.978; P<0.05 or <0.01). The gestation age, degree of asphyxia, amniotic fluid contamination, intrauterine distress and blood lactate were used as predictors to construct a nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation. The calibration curve analysis result showed that the calibration curve of the nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation tended towards the ideal curve ( C- index = 0.824, 95% CI 0.745 to 0.903). The decision curve analysis result showed that, when the risk threshold was greater than 0.18, the clinical net benefits provided by the nomogram model were higher than those of a single independent risk factor, and it could provide significant additional clinical net benefits in predicting the high risk of brain injury in children with neonatal asphyxia after resuscitation. ROC curve of internal validation analysis result that the curve (AUC) of the nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation was 0.824 (95% CI 0.744 to 0.903). ROC curve of external validation result showed that the AUC of the nomogram model for predicting brain injury in children with neonatal asphyxia after resuscitation was 0.838 (95% CI 0.714 to 0.962). Conclusions:The gestation age, degree of asphyxia, amniotic fluid contamination, intrauterine distress and blood lactate are independent risk factors for brain injury in children with neonatal asphyxia after resuscitation. The nomogram model constructed based on these factors has a high clinical benefit in predicting brain injury in children with neonatal asphyxia after resuscitation.

Objective:To evaluate preoperative high-resolution thin-layer cervical enhanced CT used to predict the venous route of the submental flap reflux vein and its relationship with adjacent structures in order to guide the anatomical understanding and protection of submental flap in pharyngeal cancer surgery.Methods:Sixty consecutive patients with pharyngeal cancer who underwent submental flap repair surgery in our department from March 2022 to December 2024, as well as 60 patients who were accepted neck dissection suffering other cancers, were selected. Before surgery, high-resolution cervical enhanced CT scans were performed, and the position of the transverse section of the facial vein in the venous phase horizontal image gradually variation tendency was focused layer by layer. The direction and adjacent relationship of the submental flap reflux veins were determined and recorded. Combined with 60 patients with other head and neck tumors who underwent neck dissection in our department during the same period (a total of 120 cases, 240 sides), the classification and management of the draining veins of Fang′s mental flap were conducted. Type Ⅰ mainly drains into the internal jugular vein; Type Ⅱ mainly drains into the external jugular vein and Type Ⅲ mainly drains into the anterior jugular vein (often accompanied by an external jugular draining branch). The status and proportion of venous drainage were analyzed.Results:Vascular predictive coincidence rate was 98.3% (59/60) among the 60 patients with pharyngeal cancer. Only one patient was predicted to have a simple return to the external jugular vein. However, during the operation, in addition to the main return to the external jugular vein, a small portion also returned to the internal jugular vein. Submental flap reflux vessels were classified into three types based on intraoperative submental flap venous return in 60 cases of laryngopharyngeal cancer, in conjunction with the analysis of venous return patterns from 240 cervical CT scans. Type Ⅰ mainly refluxed to the internal jugular vein, accounting for 42.1%. Type Ⅱ mainly refluxed to the external jugular vein (47.9%). Type Ⅲ mainly refluxed to the anterior jugular vein (10.0%). The total detection rate of CT reading of 240 venous reflux was 98.7% (237/240). Vascular predictive coincidence rate was 97.9%(235/240).Conclusion:The detailed analysis of submental venous return vessels can accurately predict the direction of reflux veins and its surrounding areas by preoperative high-resolution enhanced CT scan. This provides reliable guidance for the anatomy and protection of the submental flap reflux veins during surgery.

Objective:To compare the survival outcomes of different subsequent treatment regimens in patients with locally advanced hypopharyngeal squamous cell carcinoma (HPSCC) who achieved partial response (PR) after neoadjuvant chemotherapy based on the gross tumor volume regression rate (GTVRR).Methods:This retrospective study included patients with locally advanced HPSCC treated at the Department of Head and Neck Surgery, Beijing Tongren Hospital, from January 2011 to December 2023. The cohort included 135 males and 3 females, aged from 35 to 77 years. All patients received 2-3 cycles of TPF regimen (paclitaxel+cisplatin+5-fluorouracil) neoadjuvant chemotherapy. Subsequent treatments included concurrent chemoradiotherapy or surgery combined with postoperative adjuvant radiotherapy. The impacts of different subsequent treatment modalities on the survivals and prognoses of patients were compared based on GTVRR thresholds of 50% and 70%. The χ 2 test was used to analyze influencing factors; survival analysis and intergroup comparisons were performed using the Kaplan-Meier method and Log-rank test; prognostic factors were assessed using univariate and multivariate Cox regression analyses. Results:The 5-year OS and PFS rates were 56.5% and 47.9%, respectively, while, the 10-year OS and PFS rates were 25.8% and 21.2%, respectively. The median OS was 75 months, and the median PFS was 48 months. The laryngeal function preservation rate for the entire cohort was 83.3%. The patients who underwent surgery combined with postoperative radiotherapy had significantly better OS and PFS outcomes than those treated with concurrent chemoradiotherapy ( P<0.05). Stratification based on GTVRR revealed that the surgery plus postoperative radiotherapy regimen was particularly effective for PR patients with a GTVRR of 30%-70%, showing significantly better OS and PFS compared to the concurrent chemoradiotherapy group ( P<0.05). Conclusion:The optimal subsequent treatment for PR-HPSCC may be surgery-based comprehensive treatment, particularly for patients with a GTVRR of 30%-70%. This study offers valuable insights for the stratified treatment of HPSCC, which could contribute to improving overall patient prognosis.

Aim To investigate the expression levels of cytoplasmic FMR1-interacting protein-1(CYFIP1)in colorectal cancer and assess the impact of CYFIP1 interaction on the proliferation and apoptosis of colorec-tal cancer cell HT29,along with its potential mecha-nisms.Methods Immunohistochemistry was em-ployed to assess CYFIP1 expression in 32 colorectal cancer tissues and adjacent tissues.Coexpressed genes were identified using the GEPIA2 website to predict potential correlations and binding sites.Following the construction of a siRNA-CYFIP1,alterations in cell proliferation,apoptosis,and levels of apoptosis-related proteins were evaluated through CCK-8 assay,Hoechst 33342/PI double staining assay,and Western blot a-nalysis,respectively.Results The immunohisto-chemical findings revealed a significantly elevated level of CYFIP1 expression in colorectal cancer tissues com-pared to paracancer tissues(P<0.05).The expres-sion of CYFIP1 did not show any correlation with age and gender,but exhibited associations with TNM stage and lymph node metastasis(P<0.05).A conserved TP53 binding site was predicted in the 3kbps DNA re-gion upstream of the CYFIP1 gene using GEPIA2,JASPAR databases,and rVista 2.0 promoter prediction software.Following transfection of HT29 cells with siRNA-CYFIP1,the clonogenesis and proliferation of cells significantly decreased(P<0.05).Additional-ly,the levels of cleaved caspase-3 were elevated,while the expression levels of caspase-3 and Bcl-2 were reduced after transfection with siRNA-CYFIP1(P<0.05),which might be related to the interaction be-tween CYFIP1 and TP53.Conclusions The upregu-lation of CYFIP1 in colorectal cancer is associated with TNM stage and lymph node metastasis.Upon silen-cing,CYFIP1 demonstrates the ability to suppress pro-liferation in HT29 cells and modulate the expression of apoptotic proteins.
