ObjectiveTo observe the effects of the Fuyuan Tongluo prescription （composed of Astragali Radix， Carthami Flos， Spatholobi Caulis， Liquidambaris Fructus， Lycopodii Herba， Centellae Herba， etc.） in the treatment of restenosis with collateral obstruction syndrome after interventional operation of lower limb arteriosclerosis obliterans， and its impact on the primary patency rate. MethodsA total of 88 patients with collateral obstruction syndrome after interventional surgery for lower limb arteriosclerosis obliterans were randomly divided into two groups. The control group （n₁=44） received dual antiplatelet therapy with aspirin and clopidogrel. The observation group （n₂=44） was treated with Fuyuan Tongluo prescription non-decocted granules in addition to aspirin and clopidogrel. Both groups received treatment for 24 weeks and were followed up for 36 weeks. The changes in primary patency rate， symptom scores， ankle-brachial index （ABI）， coagulation function， and inflammatory markers before and after treatment were compared between the two groups. ResultsFor primary patency rate， after 36 weeks of treatment， the observation group had a significantly better primary patency rate than the control group （χ²=4.14，P<0.05）. After 24 weeks of treatment， there was no significant difference in primary patency rate between the two groups. Clinical efficacy comparison： Based on symptom quantification scores， and using the Nimodipine method as a reference， the overall efficacy of the observation group was superior to that of the control group after 24 weeks of treatment （χ²=2.24，P<0.05）. ABI levels： The observation group had a higher ABI than the control group after 24 and 36 weeks of treatment （P<0.05）. Coagulation function indicators： After 24 and 36 weeks of treatment， D-dimer and fibrinogen levels in both groups were lower than before treatment （P<0.05）. Inflammatory markers： After 24 and 36 weeks of treatment， CRP levels in the observation group were lower than those in the control group （P<0.05）. There were no significant differences in white blood cell （WBC） and erythrocyte sedimentation rate （ESR） levels before and after treatment between the two groups. ConclusionAdding Fuyuan Tongluo prescription non-decocted granules to dual antiplatelet therapy can improve the primary patency rate of the affected vessels in patients with lower limb arteriosclerosis obliterans after interventional surgery. Longer use of Fuyuan Tongluo prescription can significantly improve clinical symptoms， demonstrating clinical application value.

BACKGROUND:Pinoresinol diglucoside promotes bone formation and bone matrix synthesis and accelerates bone tissue repair.However,the mechanism of action and effects of this compound in osteoblasts need to be further explored. OBJECTIVE:To investigate the effect and mechanism of action of pinoresinol diglucoside on dexamethasone-treated osteoblasts based on the Wnt/β-catenin signaling pathway. METHODS:Different concentrations of dexamethasone groups and pinoresinol diglucoside groups were set to treat osteoblasts for 24 hours,and the optimal intervention concentrations were screened.Osteoblasts were treated with dexamethasone,pinoresinol diglucoside and inhibitor XAV-939.Then,control group,dexamethasone group,XVA-939 group,pinoresinol diglucoside group,pinoresinol diglucoside+XVA-939 group were set up.Cell counting kit-8 assay was used to detect cell activity.Alkaline phosphatase activity and caspase3/7 enzyme activity in cells were detected.Annexin V/PI staining and EdU assay were used to detect cell apoptosis and proliferation.Real-time qPCR and western blot were used to detect the mRNA and protein expression levels of Wnt3a,β-catenin,c-myc,osteocalcin,and type I collagen,respectively. RESULTS AND CONCLUSION:After dexamethasone and pinoresinol diglucoside intervened in osteoblasts for 24 hours,10 μmol/L dexamethasone was found to be the optimal intervention concentration for cell inhibition,and cell proliferation was most pronounced at a concentration of pinoresinol diglucoside of 100 μmol/L.Compared with the dexamethasone group,alkaline phosphatase activity was significantly enhanced(P<0.05)and caspase3/7 enzyme activity was significantly reduced(P<0.05)in the pinoresinol diglucoside group.Annexin V/PI staining and cell proliferation assay by EdU method showed that pinoresinol diglucoside inhibited apoptosis and promoted proliferation of osteoblasts after dexamethasone intervention.The mRNA and protein expression levels of Wnt3a,β-catenin,c-myc,osteocalcin,and type I collagen were significantly higher in the pinoresinol diglucoside group and pinoresinol diglucoside+XVA-939 group compared with the dexamethasone and XVA-939 groups(P<0.05).To conclude,pinoresinol diglucoside can inhibit osteoblast apoptosis after dexamethasone intervention,protect osteoblast activity and promote osteoblast proliferation by activating the Wnt/β-catenin signaling pathway,which may play a role in delaying steroid-induced osteonecrosis of the femoral head.

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.

In order to investigate the mechanical response of lumbar vertebrae during gait cycle in adolescents with idiopathic scoliosis (AIS), the present study was based on computed tomography (CT) data of AIS patients to construct model of the left support phase (ML) and model of the right support phase (MR), respectively. Firstly, material properties, boundary conditions and load loading were set to simulate the lumbar vertebra-pelvis model. Then, the difference of stress and displacement in the lumbar spine between ML and MR was compared based on the stress and displacement cloud map. The results showed that in ML, the lumbar stress was mostly distributed on the convex side, while in MR, it was mostly distributed on the concave side. The stress of the two types of stress mainly gathered near the vertebral arch plate, and the stress of the vertebral arch plate was transmitted to the vertebral body through the pedicle with the progress of gait. The average stress of the intervertebral tissue in MR was greater than that in ML, and the difference of stress on the convex and convex side was greater. The displacement of lumbar vertebrae in ML decreased gradually from L1 to L5. The opposite is true in MR. In conclusion, this study can accurately quantify the stress on the lumbar spine during gait, and may provide guidance for brace design and clinical decision making.

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.

Integrin α _v β ₃ is overexpressed in various tumor cells and angiogenesis. To date, no drug has been proven to target it for therapy. A first-in-human study was designed to investigate the safety, pharmacokinetics, and dosimetry of ¹⁷⁷Lu-AB-3PRGD2, a novel integrin α _v β ₃-targeting radionuclide drug with an albumin-binding motif to optimize the pharmacokinetics. Ten patients (3 men, 7 women; aged 45 ± 16 years) with integrin α _v β ₃-avid tumors were recruited to accept ¹⁷⁷Lu-AB-3PRGD2 injection in a dosage of 1.57 ± 0.08 GBq (42.32 ± 2.11 mCi), followed by serial scans to obtain its dynamic distribution in the body. Safety tests were performed before and every 2 weeks after the treatment for 6-8 weeks. No adverse event over grade 3 was observed. ¹⁷⁷Lu-AB-3PRGD2 was excreted mainly through the urinary system, with intense radioactivity in the kidneys and bladder. Moderate distribution was found in the liver, spleen, and intestines. The estimated blood half-life was 2.85 ± 2.17 h. The whole-body effective dose was 0.251 ± 0.047 mSv/MBq. The absorbed doses were 0.157 ± 0.032 mGy/MBq in red bone marrow and 0.684 ± 0.132 mGy/MBq in kidneys. This first-in-human study of ¹⁷⁷Lu-AB-3PRGD2 treatment indicates its promising potential for targeted radionuclide therapy of integrin α _v β ₃-avid tumors. It merits further studies in more patients with escalating doses and multiple treatment courses.

Objective: To explore the association between school climate and suicide behavior among primary and secondary school students, so as to provide recommendations for preventing student suicide in schools. Methods: From June to July 2024, a stratified cluster random sampling method was employed to conduct a questionnaire survey on suicidal behavior and school climate among 8 722 students from 36 schools in Lüliang, Linfen, and Datong cities, Shanxi Province. The relationship between school climate and suicidal behavior was analyzed using Chi square test and binary Logistic regression, supplemented by gender heterogeneity and interaction analyses. Results: The prevalence of suicidal behavior among students in Shanxi Province was 11.1%. After adjusting for age, gender, educational stage, parents educational level, residential status, family economic condition, parents marital status and depressive symptoms, binary Logistic regression analysis revealed that peer relationships ( OR=0.72, 95%CI =0.57- 0.91 ), peer trust ( OR=0.73, 95%CI =0.58-0.92), teacher support ( OR=0.66, 95%CI =0.53-0.82), school safety ( OR=0.61, 95%CI =0.48-0.78), having more than six friends ( OR=0.64, 95%CI =0.43-0.98), and school belongingness ( OR=0.70, 95%CI =0.56-0.88) among primary and secondary school students were associated with a lower risk of suicidal behavior (all P <0.05). Students who experienced school bullying showed a higher risk of suicidal behavior ( OR=2.95, 95%CI =1.80-4.82, P <0.05). Gender specific analysis revealed that peer relationships ( OR=0.67, 95%CI =0.48-0.92), peer trust ( OR=0.66, 95%CI =0.49-0.90), and school belongingness ( OR=0.62, 95%CI =0.45-0.84) were associated with a lower risk of suicidal behavior suicide behavior in girls; teacher support ( OR=0.50, 95%CI =0.36-0.70) and having more than six friends ( OR=0.51, 95%CI =0.27- 0.96 ) were associated with a lower risk of suicidal behavior in boys, who experienced school bullying showed a higher risk of suicidal behavior ( OR=4.19, 95%CI =2.18-8.03) (all P <0.05). Interactive analysis revealed that the dual interaction between peer support and school safety could reduced the risk of suicide behavior among primary and secondary school students safety ( OR= 0.83 , 95%CI=0.70-0.99, P <0.05). Conclusions School climate is closely associated with suicidal behavior among primary and secondary school students in Shanxi Province, with gender differences present. Schools should foster a positive school environment to prevent student suicide behaviors.
