This paper interprets the disease name related to bi （痹） disease in traditional Chinese medicine （TCM） from the perspective of micropathological phenotypes in knee osteoarthritis （KOA）. By systematically reviewing classical TCM literature on the pathogenesis and clinical features of different subtypes such as damp-retention bi， bone bi， and tendon bi， and integrating these with current research on pathological subtypes of KOA including the synovitis type， cartilage-meniscus type， and subchondral bone type， the study explores the correlation between traditional disease terms and modern micropathological phenotypes. The author proposes subtype classifications of damp-retention bi corresponding to synovial inflammation， bone bi related to abnormal subchondral bone remodeling， and tendon bi representing cartilage and meniscus degeneration. This approach provides a microscopic biological explanation for TCM syndrome differentiation and offers new perspectives for advancing integrative diagnostic and therapeutic strategies in both Chinese and western medicine.

Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method， it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth， leading to the production of phlegm and blood stasis， is an important pathogenesis. The invasion of external pathogenic toxins， deeply penetrating into the interior， is considered a triggering factor for the disease. The treatment focuses on supplementing the yang， consolidating the kidney， drawing fire back to its source， warming the yang， benefiting the kidney， and nourishing the spleen to generate metal. It also emphasizes unblocking the yang， transforming turbidity， and eliminating phlegm and blood stasis.

Neural oscillatory changes play a critical role in pain and analgesia research. Previous studies on pain-related neural oscillations have primarily utilized electroencephalogram (EEG) power spectral analysis, revealing a strong correlation between alpha ( α) power and subjective pain perception. However, alpha power may be influenced by the baseline of the power spectrum, making it difficult to accurately capture the true changes in alpha oscillations. This study employed power spectral analysis and further applied a power spectral parameterization method, which decomposed the power spectrum into periodic and aperiodic components, to compare EEG α power in 50 primiparous women who underwent severe pain during the first stage of labor before and after epidural analgesia. The results indicated no significant differences in α power between pre- and post-analgesia conditions. However, following power spectral parameterization, the aperiodic component of the EEG significantly decreased after analgesia, whereas the periodic component of α power showed a significant increase. This study not only validates the effectiveness and validity of the power spectral parameterization method in analgesia research but also uncovers the differential regulatory mechanism by which analgesia modulates the periodic and aperiodic components of α oscillations.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective To explore the effects and possible mechanisms of ophthalmic acupuncture combined with tail moxibustion on the behavior and hippocampus in rats with post-stroke cognitive impairment.Methods Seventy-five male SD rats were randomly divided into the sham operation group (15 rats) and the modeling group (60 rats) using the random number table method. A modified suture-occluded method was used to replicate the occlusion model of the middle cerebral artery in the modeling group,whereas only the right carotid artery was exposed in the sham operation group. After modeling,48 rats with post-stroke cognitive impairment were selected using the Morris water maze experiment,and were randomly divided into the model group,the ophthalmic acupuncture group,the tail moxibustion group and the ophthalmic acupuncture+tail moxibustion group using the random number table method,with 12 rats per group. The sham operation group and the model group were bound with no intervention;the ophthalmic acupuncture group was needled once a day in the bilateral "liver area","kidney area","heart area",and "spleen area",leaving the needle for 30 min;the tail moxibustion group was given mild-warm moxibustion on the area between "Changqiang" (GV1) and the tip of the tail for 20 min,once a day;the ophthalmic acupuncture+tail moxibustion group was given the above-mentioned ophthalmic acupuncture and tail moxibustion interventions simultaneously. After 7 days of intervention,the behavior of the rats was detected. Hematoxylin and eosin staining was used to observe the pathological changes in the hippocampus;the malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in the hippocampus were detected by colorimetric method;Western blotting was used to detect the protein expressions of Kelch-like ECH associated protein 1 (KEAP1),phosphoglycerate mutase 5 (PGAM5),apoptosis-inducing factor mitochondria associated 1 (AIFM1),nuclear factor erythroid 2-related factor 2 (Nrf2),and heme oxygenase-1 (HO-1) in the hippocampus of rats;and real-time fluorogenic quantitative PCR was used to determine the mRNA expressions of KEAP1,PGAM5,AIFM1,Nrf2,and HO-1 in the hippocampus. Results Compared with the sham operation group,the escape latency in the model group was prolonged,and the crossing platform number was decreased (P<0.05);the number of neurons in the hippocampal CA1 area was significantly decreased,with a disordered arrangement and irregular morphology,and necrotic neurons were observed;the SOD activity in the hippocampus was decreased,while the MDA content was increased (P<0.05);the protein and mRNA expressions of KEAP1,PGAM5,and AIFM1 were increased,while the protein and mRNA expressions of Nrf2 and HO-1 were decreased (P<0.05). Compared with the model group,the escape latency of rats in the ophthalmic acupuncture+tail moxibustion group was shortened,and the crossing platform number was increased (P<0.05);the loss of neurons in the hippocampal CA1 area of the rat was significantly reduced,and the cell morphology was more plump;SOD activity in the hippocampus was increased,and MDA content was decreased (P<0.05);and the protein and mRNA expressions of KEAP1,PGAM5,and AIFM1 were decreased,while the protein and mRNA expressions of Nrf2 and HO-1 were increased (P<0.05).Conclusion The combination of ophthalmic acupuncture and tail moxibustion can be used to treat rats with post-stroke cognitive impairment,and its mechanism may be related to alleviating oxidative stress damage and oxeiptosis in the hippocampus,thereby improving the degree of hippocampal neuronal damage and enhancing the cognitive ability of rats after stroke.

Background::Triple-negative breast cancer (TNBC) is a type of highly invasive breast cancer with a poor prognosis. According to new research, long noncoding RNAs (lncRNAs) play a significant role in the progression of cancer. Although the role of lncRNAs in breast cancer has been well reported, few studies have focused on TNBC. This study aimed to explore the biological function and clinical significance of forkhead box C1 promoter upstream transcript (FOXCUT) in triple-negative breast cancer.Methods::Based on a bioinformatic analysis of the cancer genome atlas (TCGA) database, we detected that the lncRNA FOXCUT was overexpressed in TNBC tissues, which was further validated in an external cohort of tissues from the General Surgery Department of the First Affiliated Hospital of Nanjing Medical University. The functions of FOXCUT in proliferation, migration, and invasion were detected in vitro or in vivo. Luciferase assays and RNA immunoprecipitation (RIP) were performed to reveal that FOXCUT acted as a competitive endogenous RNA (ceRNA) for the microRNA miR-24-3p and consequently inhibited the degradation of p38. Results::lncRNA FOXCUT was markedly highly expressed in breast cancer, which was associated with poor prognosis in some cases. Knockdown of FOXCUT significantly inhibited cancer growth and metastasis in vitro or in vivo. Mechanistically, FOXCUT competitively bounded to miR-24-3p to prevent the degradation of p38, which might act as an oncogene in breast cancer. Conclusion::Collectively, this research revealed a novel FOXCUT/miR-24-3p/p38 axis that affected breast cancer progression and suggested that the lncRNA FOXCUT could be a diagnostic marker and therapeutic target for breast cancer.

Osteoporosis and knee osteoarthritis often co-occur and are closely related in terms of epidemiology， clinical symptoms， pathogenesis and other aspects. Therefore， it is necessary to manage the co-morbidity and treat the two as a whole. Based on the overall relationship between wei （痿） and bi （痹） in TCM， it is believed that osteoporosis and knee osteoarthritis have marrow loss and bone atrophy as the core pathogenesis of co-morbidity， and microfractures as the central pathological link. The overall treatment is rooted in boosting kidney， supplementing marrow and strengthening the bones. According to the pathological manifestations of microfractures in the process of co-morbidity， and the different deficiency and excess characteristics of wei and bi， it can be divided into three types， "wei emerging with mild bi"， "wei and bi progressing simultaneously"， and "emphasis on both wei and bi"， for treatment. In terms of "wei emerging with mild bi"， that is the early stage of osteoporosis， the traditional Daoyin （导引） is the main therapy. For "wei and bi progressing simultaneously"， it can be divided into three stages further， including the onset stage， remission stage， and recovery stage of knee pain， treated with Taohong Siwu Decoction （桃红四物汤）， Bushen Huoxue Formula （补肾活血方） and self-made Bushen Qianggu Formula （补肾强骨方） as the main formula respectively. For "emphasis on both wei and bi"， the proven formula， Qianggu Zhitong Formula （强骨止痛方）， is taken as the main prescription.

Objective To study the expression and clinical significance of neural Wiskott-Alrdich syndrome protein(N-WASP)in pla-centas with preeclampsia.Methods This study included a total of 65 pregnant women:15 in the early-onset preeclampsia group,15 in the early-onset control group,15 in the late-onset preeclampsia group,and 20 in the late-onset control group.Real-time fluorescence quan-titative PCR(RT-qPCR)was used to detect the relative expression of N-WASP mRNA in placental tissues.Western blotting and immu-nohistochemistry were used to detect the expression and position of N-WASP protein in placental tissues from each group.Results RT-qPCR revealed significantly lower N-WASP mRNA expression levels in the placental tissue of the early-onset preeclampsia group compared to those in the early-onset control group(0.50±0.19 vs.0.93±0.73,P＜0.05).The N-WASP mRNA expression levels in late-onset preeclampsia placenta were significantly lower than those in the late-onset control group(0.83±0.34 vs.1.15±0.34,P＜0.05).Western blotting revealed significantly lower N-WASP protein expression in the placental tissue of early-onset preeclampsia compared to that in the early-onset control group(0.35±0.17 vs.0.72±0.21,P＜0.05).The N-WASP protein expression in late-onset preeclampsia placenta was significantly lower than that in the late-onset control group(0.39±0.16 vs.0.76±0.20,P＜0.05).The N-WASP mRNA expression in the placenta negatively correlated with the occurrence of early-onset(r =-0.37,P = 0.042)and late-onset preeclampsia(r =-0.39,P = 0.019).Immunohistochemistry revealed that N-WASP protein was localized in the cytoplasm of syncytiotrophoblasts,cytotrophoblasts,villous stromal cells,and vascular endothelial cells.Conclusion The low expression of N-WASP may be closely associated with preeclampsia.

Objective:To investigate the efficacy of robot-assisted femoral tunnel localization in reconstruction of the medial patellofemoral ligament (MPFL).Methods:A retrospective study was conducted to analyze the 36 patients who had been admitted to Department of Sports Medicine, The Fourth Hospital of Wuhan between January 2019 and January 2022 due to recurrent patellar dislocation. There were 15 males and 21 females; age: 23.5 (18.3, 29.0) years; number of dislocations: 2.5 (2.0, 3.0). They were stratified into 2 cohorts based on utilization of robot-assistance. In the observation group (17 cases), the femoral tunnel localization was robot-assisted in MPFL reconstruction; in the control group (19 cases), the femoral tunnel localization was guided by C-arm fluoroscopy in MPFL reconstruction. The 2 groups were compared in terms of operation time, frequency of guide wire placement, visual analogue scale (VAS) at postoperative 1 d, patellar tilt angle (PTA) and the disparity between actual femoral tunnel insertion and ideal tunnel insertion point (Sch?ttle point) at postoperative 1 to 3 d, and Lysholm knee score and International Knee Documentation Committee (IKDC) score at the last follow-up.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). All patients were followed up for 12.0 (10.3, 13.0) months. In the observation group, the operation time [(64.1±16.7) min], frequency of guide wire placement [1.0 (1.0, 2.0) times], VAS [2.5 (2.0, 3.0) points], and disparity between actual femoral tunnel insertion and ideal tunnel insertion point [(4.7±1.2) mm] were significantly better than those in the control group [(84.2±19.7) min, 3.0 (2.0, 4.0) times, 3.5 (3.0, 4.0) points, and (6.1±1.2) mm] ( P<0.05). There was no statistical difference between the 2 groups in PTA, Lysholm knee score or IKDC score ( P>0.05). Conclusions:The short-term clinical efficacy of robot-assisted femoral tunnel localization is satisfactory in MPFL reconstruction. Compared with the intraoperative C-arm fluoroscopy, robot-assisted localization can decrease the frequency of guide wire placement, enhance femoral tunnel accuracy and efficiency, and alleviate more postoperative pain for the patients.
