Objective:To evaluate the safety and efficacy of accelerator-based boron neutron capture therapy (AB-BNCT) in the treatment of recurrent and refractory malignant tumors.Methods:The data of 14 patients admitted to Xiamen Humanity Hospital from September 2022 to April 2023 were prospectively collected, including 7 patients with primary brain malignancies and 7 patients with locally recurrent inoperable head and neck malignancies. All patients received intravenous infusion of boron drug (NBB-001, p-dihydroxyborylphe nylalanine, a patented freeze-dried formulation) at a total nominal dosage of 500 mg/kg (11 patients) or 750 mg/kg (3 patients), and were irradiated with neutrons (operating with NeuPex system). Adverse events after treatment were recorded and assessed. The primary efficacy endpoint was the 90 d objective response rate (ORR), while the secondary endpoints included progression-free survival (PFS) and complete response rate (CRR). Data were compiled and analyzed by SAS 9.4 software. The rate and 95% CI were calculated using Clopper-Pearson method. Results:The median dose delivered to 80% of the target volume (D 80%) was 16.80 GyE (range: 8.93-23.79 GyE). The most common adverse reactions were hyperamylasemia, alopecia, and hyperprolactinemia. Five patients experienced 8 cases of grade 3 or above adverse events, including 1 case of grade 4 acute kidney injury and 7 cases of grade 3 adverse events. All adverse events were recovered after observation or treatment. At 90 d after treatment, the ORR of all patients was 9/14 (64%, 95% CI: 35%-87%), disease control rate (DCR) was 10/14 (71%, 95% CI: 42%-92%), CRR was 2/14 (14%, 95% CI: 2%-42%); and the best overall response during the entire course included an ORR of 10/14 (71% ,95% CI: 42%-92%), DCR of 13/14 (93%, 95% CI: 66%-100%), and CRR of 3/14 (21% ,95% CI: 5%-51%). The 1-year survival rate for head and neck malignancies was 71.4%, and the 2-year survival rate was 42.8%. The 1-year survival rate for recurrent brain malignancies was 42.8%. Conclusion:AB-BNCT demonstrates favorable safety and promising efficacy in treating primary brain malignancies and recurrent/refractory head and neck malignancies, representing a potential therapeutic option.

Objective This study aims to explore the efficacy and complication rates of the transcranial approach(TCA)and extended endoscopic endonasal approach(EEEA)for the treatment of craniopharyngiomas based on the QST classification,providing a scientific reference for clinical decision-making on surgical approach.Methods A total of 151 patients who underwent craniopharyngioma surgery at our center from January 2018 to December 2023 were enrolled.The patients were categorized into Q-CP(suprasellar type),S-CP(infundibular type),and T-CP(tuberal type)according to the QST classification.Systematic collection and analysis were performed on the outcomes of TCA and EEEA treatments,respectively.The differences in effectiveness between the two approaches were evaluated based on the QST classification.Results The improvement rate of visual symptoms was overall higher in the EEEA group than in the TCA group(59.1%vs.36.5%,P=0.006),and the visual deterioration rate was lower(3.0%vs.14.1%,P=0.006).However,the incidence of cerebrospinal fluid leakage was higher in the EEEA group(15.2%vs.3.5%,χ2=4.986,P=0.026).The incidence of postoperative seizures(8.2%vs.0,P=0.019),brain contusions(10.6%vs.0,P=0.005),and subdural hematoma(9.4%vs.0%,P=0.01)was higher in the TCA group.For patients with Q-CP type,the EEEA group had a higher rate of total tumor resection(92.9%vs.65.2%,P=0.025)and a lower recurrence rate(3.6%vs.21.7%,P=0.047),with shorter hospital stays and lower postoperative costs.The TCA group had higher intraoperative blood loss in this type(300 mL vs.200 mL,Z=-2.261,P=0.024).For S-CP type patients,the EEEA group showed a higher rate of total tumor resection(91.3%vs.74.2%)and a lower recurrence rate(0 vs.12.9%,P=0.031),with lower postoperative hospital costs.In T-CP type,due to the deeper location,EEEA showed limitations in protecting hypothalamic function and the TCA group had a better postoperative hypothalamic function score(P=0.035).Conclusion Based on QST classification,EEEA has advantages in Q-CP and S-CP types and is recommended as the preferred surgical procedure;In the T-CP type,TCA surgery is more helpful in protecting hypothalamic function.

Objective:To observe the therapeutic effects of electroacupuncture(EA)stimulation on chronic pain and associated negative emotions,and to investigate the activity changes of glutamatergic neurons in the primary motor cortex(M1)following EA stimulation.Methods:Male C57BL/6J mice were randomly divided into four groups:sham surgery(Sham),pure electroacupuncture stimulation(EA),nerve injury(SNI)and electroacupuncture treatment of nerve injury(SNI+EA).Thirty days after the SNI model establishment,EA stimulation was administered bilaterally to the Zusanli(ST36)acupoints in mice.von Frey filaments and Hargreaves heat sensitivity testing were used to detect mechanical and thermal hyperalgesia.The elevated plus maze test was conducted to assess the impact on anxiety-like behaviors in mice.Dual immunofluorescence staining was employed to observe changes in c-Fos expression in M1 gluta-matergic neurons.Results:As compared to Sham group,SNI-treated mice exhibited significant mechanical and thermal hyperalgesia in bilateral hindpaws at 30 days post-modeling(P＜0.01)and displayed obvious anxiety-like behaviors(P＜0.01).The SNI+EA group showed significant relief in pain and anxiety-like behaviors(P＜0.01).c-Fos expression in M1 glutamatergic neurons was significantly decreased in SNI mice.Conversely,after electroacupuncture(EA)treatment,compared to the SNI group,M1 glutamatergic neurons in the SNI+EA group showed significantly in-creased c-Fos expression(P＜0.01).Conclusion:Electroacupuncture significantly alleviated chronic pain and associ-ated anxiety-like behaviors induced by SNI,which might involve the activation of glutamatergic neurons in the M1 in this process.

Objective To analyze the acupoint selection law in acupuncture treatment for sinusitis using data mining techniques.Methods Relevant literature on acupuncture treatment for sinusitis was retrieved from CNKI,Wanfang Data,VIP and CBM from January 1,2000 to December 20,2024.Descriptive statistics were performed on the frequency of acupoint usage,meridian tropism,and regional distribution.SPSS Modeler 18.0,Cytoscape 3.10.3 and Origin Pro were employed to conduct association rule mining,co-occurrence network analysis,and systematic cluster analysis on the acupoints.Results A total of 69 articles were included,yielding 114 acupoint prescriptions involving 65 distinct acupoints.The most frequently used acupoints were Yingxiang,Yintang and Hegu,etc.;the most commonly used meridians were large intestine meridian,Governor Vessel,gallbladder meridian and bladder meridian.Acupoint selection was predominantly concentrated in the head/neck region,lower limbs and upper limbs.Among the specific acupoint categories,Jiaohui acupoint,Wushu acupoint and Yuan acupoint were used most frequently.The acupoint combinations with the strongest associations were Hegu-Yingxiang,Hegu-Yintang-Yingxiang and Fengchi-Yingxiang.The top 22 high-frequency acupoints could be grouped into 5 clusters.Conclusion Acupuncture treatment for sinusitis can exert the functions to disperse wind and unblock the orifices,drain heat and resolve turbidity,expel pathogens and alleviate pain,tonify deficiency and dissipate cold,as well as harmonize qi and blood.The characteristics of acupoint combination include a primary focus on local points supplemented by distal points,pattern differentiation-based selection,and a propensity for unblocking yang qi.The core acupuncture formula is Yingxiang-Yintang-Hegu-Fengchi.

To investigate the effect of capsaicin(CAP)on the replication of bovine viral diarrhea vi-rus(BVDV).Bovine nasal turbinate osteoblasts(BT)infected with BVDV served as the research model,and viral gene and protein levels were evaluated using RT-qPCR and Western blot.Moreo-ver,molecular docking,molecular dynamics simulation,and oil red O staining were applied to ana-lyze the mechanism by which CAP inhibits BVDV replication.The results revealed no significant effect of CAP at 6.25,12.5,25,and 50 mg/L on the viability of BT cells.CAP was found to signifi-cantly inhibit BVDV 5′UTR RNA and E2 protein levels,according to the antiviral effect study.Molecular docking and molecular dynamics simulations indicated that CAP could bind with high affinity to the active site of PI3K.Additional mechanistic studies indicated that CAP significantly reduced the activation of the PI3K/AKT signaling pathway triggered by BVDV.Furthermore,CAP notably decreased the mRNA levels of FASN,SREBP-1,and ACC-1,which are crucial fatty acid synthesis enzymes in the downstream PI3K/AKT signaling pathway,as well as the levels of lipid droplets.Interestingly,the addition of exogenous oleic acid greatly diminished the antiviral effec-tiveness of CAP and significantly lowered the mRNA levels of IFN-α and IFN-β.The results reveal for the first time that CAP can inhibit BVDV replication,establishing a foundation for its preven-tion and the development of feed additives.
