ObjectiveTo evaluate the effect of Ningying Formula （宁瘿方） combined with low-dose antithyroid drugs （ATDs） on the relapse risk for patients with Graves' hyperthyroidism （GH） during the remission phase， and to analyze the related factors between GH relapse and thyrotropin receptor antibody （TRAb） negativity， so as to provide evidence for the standardized management of GH in remission stage. MethodsA single-center retrospective cohort study was conducted， including 269 GH patients in the remission stage. After propensity score matching （PSM）， 102 matched pairs （204 patients） were established. The control group received low-dose ATDs as maintenance therapy， while the exposure group received the core Ningying Formula in addition to low-dose ATDs. The primary outcome was the GH recurrence rate； the secondary outcome was the thyrotropin receptor antibody （TRAb） negativity rate （TRAb＜1.75 IU/L）. Safety outcomes included treatment-related adverse events. Differences between groups were assessed using Cox regression models and Kaplan-Meier curves， with sensitivity analysis performed using inverse probability of treatment weighting （IPTW）. ResultsThe median follow-up in the matched cohort was 28.07 months. Regarding the GH recurrence outcome， the recurrence rate in the exposure group （18/102， 17.6%） was significantly lower than that in the control group （31/102， 30.4%； χ²=4.539， P=0.033）； regarding the TRAb negativity outcome， the TRAb negativity rate in the exposure group （50/102， 49.0%） was significantly higher than that in the control group （23/102， 22.5%； χ²=15.551， P＜0.001）. Multivariate Cox regression analysis for recurrence showed that Ningying Formula treatment reduced the risk of recurrence ［HR=0.324， 95%CI（0.170， 0.617）， P＜0.001］. Male ［HR=2.209， 95%CI（1.079， 4.520）， P=0.030］， higher initial TRAb level ［per 1 IU/L increase： HR=1.033， 95%CI（1.003， 1.064）， P=0.032］， and larger thyroid volume ［per 1 ml increase： HR=1.045， 95%CI（1.003， 1.088）， P=0.035］ were identified as independent risk factors for recurrence； multivariate Cox regression analysis for TRAb negativity indicated that Ningying Formula treatment promoted TRAb negativity ［HR=1.826， 95%CI（1.091， 3.056）， P=0.022］， while a higher initial TRAb level was associated with a lower probability of negativity ［HR=0.974， 95%CI（0.950， 0.998）， P=0.032］. Survival analysis showed significant differences in relapse rate between groups （Log-Rank P=0.003） and in TRAb outcomes （Log-Rank P=0.034）. The incidence of treatment-related adverse events was similar between groups （P=0.757）. The IPTW sensitivity analysis was consistent with the primary analysis， indicating robust results. ConclusionThe Ningying Formula combined with low-dose ATDs can significantly reduce the risk of recurrence and can improve the TRAb negativity rate in GH patients during the remission stage， without increasing common adverse events， making it an optional strategy for reducing relapse risk during remission. Male gender， higher baseline TRAb level， and larger thyroid volume indicate a higher risk of recurrence， warranting focused follow-up and stratified management.

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 investigate the effect mechanism of Gualou guizhi granule on neurological function and synaptic plasticity in rats with cerebral ischemia-reperfusion injury. METHODS The rats were randomly divided into sham operation group， model group and Gualou guizhi granule group （3.6 g/kg）， with 6 rats in each group. The cerebral ischemia-reperfusion injury model was established by the suture occlusion method. Two hours after modeling， the model rats were given relevant medicine or normal saline intragastrically， once a day， for 7 consecutive days. After the last medication， the neurological function of rats was evaluated [calculated by modified neurological severity scores （mNSS） and corner turning percentage]； the neuronal apoptosis rate of brain histiocyte in the ischemic side of rats was detected in each group； the positive expressions of growth associated protein 43 （GAP43） and microtubule associated protein 2 （MAP2） were detected； protein expressions of neuron-specific nuclear protein （NeuN）， synaptophysin-1 （Syn-1）， postsynaptic density protein-95 （PSD-95）， peroxisome proliferators-activated receptor γ （PPARγ）， brain-derived neurotrophic factor （BDNF） and tropomyosin receptor kinase B （TrkB）， as well as mRNA expressions of NeuN， Syn-1 and PSD-95 were detected. RESULTS Compared with the model group， mNSS， corner turning percentage and neuronal apoptotic rate were decreased significantly in Gualou guizhi granule group （P＜0.01）； GAP43 represented weak immunoreactivity， and MAP2 represented moderate immunoreactivity； protein expressions of NeuN， Syn-1， PSD-95， PPARγ， BDNF， TrkB and mRNA expressions of Syn-1， NeuN， PSD-95 were all increased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Gualou guizhi granule can promote synaptic plasticity by activating BDNF/TrkB signaling pathway， thus playing a protective role in cerebral ischemia-reperfusion injury in rats.

This study aimed to identify subtypes of genomic variants associated with the efficacy of immune checkpoint inhibitors (ICIs) by conducting systematic literature search in electronic databases up to May 31, 2021. The main outcomes including overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and durable clinical benefit (DCB) were correlated with tumor genomic features. A total of 1546 lung cancer patients with available genomic variation data were included from 14 studies. The Kirsten rat sarcoma viral oncogene homolog G12C (KRAS^G12C) mutation combined with tumor protein P53 (TP53) mutation revealed the promising efficacy of ICI therapy in these patients. Furthermore, patients with epidermal growth factor receptor (EGFR) classical activating mutations (including EGFR^L858R and EGFR^Δ19) exhibited worse outcomes to ICIs in OS (adjusted hazard ratio (HR), 1.40; 95% confidence interval (CI), 1.01‍‒‍1.95; P=0.0411) and PFS (adjusted HR, 1.98; 95% CI, 1.49‍‒‍2.63; P<0.0001), while classical activating mutations with EGFR^T790M showed no difference compared to classical activating mutations without EGFR^T790M in OS (adjusted HR, 0.96; 95% CI, 0.48‍‒‍1.94; P=0.9157) or PFS (adjusted HR, 0.72; 95% CI, 0.39‍‒‍1.35; P=0.3050). Of note, for patients harboring the Usher syndrome type-2A(USH2A) missense mutation, correspondingly better outcomes were observed in OS (adjusted HR, 0.52; 95% CI, 0.32‍‒‍0.82; P=0.0077), PFS (adjusted HR, 0.51; 95% CI, 0.38‍‒‍0.69; P<0.0001), DCB (adjusted odds ratio (OR), 4.74; 95% CI, 2.75‍‒‍8.17; P<0.0001), and ORR (adjusted OR, 3.45; 95% CI, 1.88‍‒‍6.33; P<0.0001). Our findings indicated that, USH2A missense mutations and the KRAS^G12Cmutation combined with TP53 mutation were associated with better efficacy and survival outcomes, but EGFR classical mutations irrespective of combination with EGFR^T790M showed the opposite role in the ICI therapy among lung cancer patients. Our findings might guide the selection of precise targets for effective immunotherapy in the clinic.

Objective:To observe the clinical characteristics and guideline compliance of chronic obstructive pulmonary disease (COPD) patients with initial triple therapy in real-life world.Methods:This study is a cross-sectional study. The subjects of the study were COPD patients admitted to 13 hospitals in Hunan Province and Guangxi Zhuang Autonomous Region from December 2016 to December 2021. The initial treatment was triple inhaled drugs. The data collected included gender, age, diagnosis, body mass index (BMI), history of acute exacerbation (AE) in the past year, pulmonary function, COPD Assessment Test (CAT) score, modified British Medical Research Council Dyspnea Questionnaire (mMRC), inhaled drugs and other indicators. The characteristics and differences of COPD patients before and after 2020 were analyzed.Results:7 184 patients with COPD were enrolled in this study, including 2 409 COPD patients treated with initial triple therapy, accounting for 33.5%(2 409/7 184). Taking January 1st, 2020 as the cut-off point, 1 825 COPD patients (75.8%) received initial treatment with triple inhaled drugs before 2020 and 584 patients (24.2%) after 2020 were included in this study. Compared with COPD patients before 2020, the COPD patients after 2020 had higher FEV 1% [(40.9±15.5 )% vs (39.3±15.5)%, P=0.040], lower CAT [(15.8±6.5)point vs (17.5±6.2)point, P<0.001], less AE in the past year [1(0, 2)times vs 1(0, 2)times, P=0.001] and higher rate of non-AE [255(43.7%) vs 581(37.1%), P=0.006]. In addition, before 2020, patients with COPD were mainly treated with open triple drugs (1 825/1 825, 100%); after 2020, 306 patients (52.4%) received open triple inhaled drugs, and 278 patients (47.6%) received closed triple inhaled drugs. Conclusions:In real-life world, most of patients with COPD treated with triple therapy have severe lung function, obvious symptoms and high risk of acute exacerbation. The real-world prescribing of triple therapy in patients with COPD does not always reflect recommendations in guidelines and strategies, and overtreatment is common. After 2020, prescribing triple therapy for COPD patients is more positive and worse consistency with guideline.
