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 of different radiotherapy doses on the prognosis of patients with stage cT1-4N0M0 esophageal squamous cell carcinoma(ESCC)who received radical radio(chemo)therapy categorized into subgroups with different tumor local factors.Methods A retrospective analysis was conducted on 256 patients with clinically nonmetastatic esophageal squamous cell carcinoma.The optimal cutoff for tumor local factors was determined.The relationship between latest treatment efficacy and tumor local factors was analyzed,and independent indicators affecting patient overall survival(OS)were examined using multivariate analysis.The subgroup analysis was performed to determine the correlation between selected factors and radiation therapy doses.Results The shorter the X-ray length of esophageal tumor lesion and the smaller the lesion canal wall thickness and gross tumor volume(GTV),the better the latest treatment efficacy of the patients(χ2=9.066,10.310,15.661,respectively,P=0.011,0.006,P＜0.001).Multivariate analysis results showed that GTV(P＜0.001),radiation dose(P=0.038),and latest treatment efficacy(P＜0.001)were independent predictors of the patients'OS,and the latter two were also independent predictors of the patients'progression-free survival(PFS)(P=0.033,＜0.001).Subgroup analysis further showed that high doses of radiotherapy(over 60 Gy)resulted in good OS(χ2=5.040,4.588,5.400,P=0.025,0.032,0.020)and PFS(χ2=6.089,4.353,6.459,P=0.014,0.037,0.011)in the subgroup with maximum wall thickness below 3.7 cm,with esophageal lesions with GTV below 37.34 cm3,or not receiving simultaneous chemotherapy.Conclusion Local tumor factors are important prognostic factors of ESCC patients treated with radical radio(chemo)therapy.Patients with thin lesion walls and small tumor volumes may greatly benefit from high doses of radiation(over 60 Gy).

To systematically review randomized controlled trials （RCTs） of traditional Chinese medicine （TCM） intervention in ulcerative colitis （UC）， and analyze the characteristics of these studies and their outcome indicators， thereby providing references for the design of future RCTs of TCM intervention in UC and offering evidence supporting the clinical application of TCM in UC. A computerized search was conducted in the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SinoMed， PubMed， Cochrane Library， EMbase， and Web of Science databases for RCTs of TCM intervention in UC published from January 2021 to August 2024. The risk of bias was assessed， and outcome indicators were qualitatively analyzed. A total of 555 RCTs were included， with a sample size of 44 853 participants. The largest sample size was 218 cases， and the smallest was 28 cases， with most studies focusing on 60-100 participants. Of the 386 RCTs that explicitly reported TCM syndrome types， the top three were large intestine dampness-heat syndrome （31.05%）， spleen and kidney yang deficiency syndrome （12.47%）， and spleen deficiency with dampness syndrome （9.17%）. The interventions， ranked by frequency of use， included internal Chinese medicine compounds/preparations （64.5%）， Chinese medicine compounds/preparations with retained enema （18.2%）， internal Chinese medicine compounds/preparations + external TCM treatment （5.95%）， and external TCM treatment alone （4.86%）. The treatment duration was mainly 4-8 weeks （64.86%）， with 61 studies （10.99%） reporting follow-up time. A total of 157 outcome indicators were used， with a frequency of 3 460 occurrences， classified into six domains： TCM syndromes and symptoms （346 occurrences， 10%）， symptoms/signs （541 occurrences， 15.64%）， physical and chemical examinations （2 119 occurrences， 61.24%）， quality of life （107 occurrences， 3.09%）， long-term prognosis （61 occurrences， 1.76%）， and safety events （284 occurrences， 8.21%）. The analysis reveals several limitations in the outcome indicators of TCM intervention in UC， including the lack of a basis for sample size calculation， non-standardized TCM syndrome classification， absence of trial design and registration， inadequate blinding and allocation concealment， adherence issues with interventions， imbalanced selection of surrogate and endpoint indicators， inconsistency in the timing of outcome measurements， design issues that require standardization， and ethical and safety concerns. It is recommended that future studies actively construct a set of core indicators for UC that include standardized TCM syndrome classification， clear efficacy evaluation indicators， key endpoint indicators， and reasonable measurement time points. Long-term prognostic impacts， comprehensive assessments of patients' quality of life， and consideration of economic benefits should be emphasized， providing a basis for the clinical practice of TCM in the treatment of UC.

Objective:To explore the impacts of two radiotherapy modalities, elective nodal irradiation (ENI) and involved-field irradiation (IFI), on the prognosis of patients with clinical T 1~4N 0M 0 esophageal squamous cell carcinoma (ESCC) treated with definitive (chemotherapy) radiotherapy. Methods:A retrospective analysis was conducted on the prognosis of 324 patients with clinical T 1-4N 0M 0 ESCC, focusing on the impacts of ENI and IFI on the prognosis of these patients. Propensity score matching (PSM) analysis was performed based on the different composition ratios of the two groups, and stratified analysis was conducted for patients of different stages. Results:All the patients presented a median overall survival (OS) of 33.1 months (95% CI: 28.1-38.1) and a median progression-free survival (PFS) of 22.3 months (95% CI: 18.2-26.4). There were 97 patients in the ENI group and 227 patients in the IFI group. The ENI group exhibited higher OS and PFS than the IFI group ( χ2 = 4.31, 4.10, P < 0.05). After 1∶1 PSM analysis, each of the groups contained 75 cases. Multivariate analysis revealed that independent factors affecting patient OS included patient age, gross tumor volume (GTV), and irradiation modality ( χ2 = 7.93, 5.88, 4.59, P < 0.05) and PFS ( χ2 = 7.10, 5.26, 3.39, P < 0.05). Further stratified analysis indicated that ENI yielded significantly better efficacy than IFI for patients with cT 1 and T 2stage ESCC ( χ2 = 9.41, 7.88, P < 0.05). However, this advantage was not found in T 3 and T 4 patients ( P > 0.05). There was no statistically significant difference in the incidence of radiation esophagitis and radiation pneumonia between both groups ( P > 0.05). Conclusions:Patients with clinical T 1-4N 0M 0 ESCC who undergone definitive (chemotherapy) radiotherapy may benefit from ENI, particularly those in the cT 1 and cT 2 stages, for whom ENI is recommended for definitive radiotherapy.

ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure （HBV-ACLF） at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients， including 618 in the early stage， 355 in the middle stage， and 85 in the late stage， were collected from 18 clinical centers across 12 regions nationwide from January 1， 2012 to February 28， 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients， like the four diagnostic information （including symptoms， tongue， pulse） of traditional Chinese medicine （TCM）， and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients， and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries， including 36 symptom information， 12 tongue information， and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF， which were liver-gallbladder damp-heat pattern， qi deficiency and blood stasis pattern， liver-kidney yin deficiency pattern， and spleen-kidney yang-deficiency pattern. In the early stage， heat （39.4%， 359/912） and dampness （27.5%， 251/912） were most common， and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern （74.6%， 461/618）； in the middle stage， dampness （30.2%， 187/619） and blood stasis （20.7%， 128/619） were most common， and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern （53.2%， 189/355）， and qi deficiency and blood stasis pattern （27.6%， 98/355）； and in the late stage， the pattern of the disease was dominated by qi deficiency （26.3%， 40/152） and yin deficiency （20.4%， 31/152）， and the patterns were dominated by qi deficiency and blood stasis pattern （36.5%， 31/85）， and liver-gallbladder damp-heat pattern （25.9%， 22/85）. ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF， presenting an overall trend of evolving patterns as "from excess to deficiency， transforming from excess to deficiency"， which is damp-heat → blood stasis → qi-blood yin-yang deficiency.

Objective:To analyze the local recurrence patterns after concurrent chemoradiotherapy (CCRT) for thoracic esophageal squamous cell carcinoma (ESCC) through image fusion, and to explore the risk factors of local recurrence and its relationships with dosimetric indices.Methods:A retrospective analysis was conducted for 209 thoracic ESCC patients who received radical CCRT in Fourth Hospital of Hebei Medical University during 2016-2019. For the patients diagnosed as the local recurrence of esophageal lesions, their CT images were fused with the original planning CT images using image registration software to identify the recurrence sites. Through 1∶1 propensity score matching (PSM) of the clinal data of patients with local recurrence (the recurrence group, nbefore = 81, nafter = 62) and those without local recurrence (the recurrence-free group, nbefore = 128, nafter=62), the dose and volume parameters of the treatment plans for the two groups were compared. Univariate and multivariate analyses were conducted using the Kaplan-Meier method and the Cox regression model to analyze the factors affecting the overall survival (OS), progression-free survival (PFS), and recurrence-free survival (RFS). Results:All patients had 1-, 3-, and 5-year OS rates of 80.9%, 42.6%, and 33.0%, respectively, 1-, 3-, and 5-year PFS rates of 67.9%, 34.0%, and 27.9%, respectively, and 1-, 3-, and 5-year RFS rates of 71.3%, 39.2%, and 30.5%, respectively. T stage, N stage, and radiation dose were independent prognostic factors for the OS, PFS, and RFS ( HR = 1.42-1.87, P < 0.05) of the patients, respectively. Among 68 patients with local recurrence, 62 cases (91.2%) suffered recurrence within the gross tumor volume (GTV). The dose and volume parameters of patients with local recurrence, such as GTV- D95%, clinical target volume (CTV)- D95%, GTV- D50%, CTV- D50%, and planning target volume (PTV)- D50%, GTV- V60, CTV- V60, and PTV- V60, were significantly lower than those of patients free from the local recurrence ( t=1.90-2.15, P < 0.05). Conclusions:Local recurrence of patients with thoracic ESCC after radical CCRT occurs mainly within the GTV. Increasing radiation doses may contribute to their survival benefits. The D50% for each target volume in the radiotherapy plan may be related to local recurrence, and it is necessary to conduct further research.

Objective:To investigate the prognostic value of Onodera's prognostic nutrition index (PNI) before treatment in patients with cervical and upper thoracic esophageal squamous cell carcinoma (CUTESCC) undergoing definitive chemoradiotherapy (dCRT) and its predictive value in the occurrence of ≥ grade 2 radiation esophagitis (RE).Methods:The data of 163 CUTESCC patients eligible for inclusion criteria admitted to the Fourth Hospital of Hebei Medical University from January 2012 to December 2017 were retrospectively analyzed. The receiver operating characteristic (ROC) curve was used to calculate the best cut-off value of PNI for predicting the prognosis of patients. The prognosis of patients was analyzed by univariate and Cox multivariate analyses. Logistics binary regression model was adopted to analyze the risk factors of ≥ grade 2 RE in univariate and multivariate analyses. The significant factors in logistic multivariate analysis were used to construct nomogram for predicting ≥ grade 2 RE.Results:The optimal cut-off value of PNI was 48.57 [area under the curve (AUC): 0.653, P<0.001]. The median overall survival (OS) and progression-free survival (PFS) were 26.1 and 19.4 months, respectively. The OS ( χ2=6.900, P=0.009) and PFS ( χ2=9.902, P=0.003) of patients in the PNI ≥ 48.57 group ( n=47) were significantly better than those in the PNI < 48.57 group ( n=116). Cox multivariate analysis showed that cTNM stage and PNI were the independent predictors of OS ( HR=1.513, 95% CI: 1.193-1.920, P=0.001; HR=1.807, 95% CI: 1.164-2.807, P=0.008) and PFS ( HR=1.595, 95% CI: 1.247-2.039, P<0.001; HR=2.260, 95% CI: 1.439-3.550, P<0.001). Short-term efficacy was another independent index affecting PFS ( HR=2.072, 95% CI: 1.072-4.003, P=0.030). Logistic multivariate analysis showed that the maximum transverse diameter of the lesion ( OR=3.026, 95% CI: 1.266-7.229, P=0.013), gross tumor volume (GTV) ( OR=3.456, 95% CI: 1.373-8.699, P=0.008), prescription dose ( OR=3.124, 95% CI: 1.346-7.246, P=0.009) and PNI ( OR=2.072, 95% CI: 1.072-4.003, P=0.030) were the independent factors affecting the occurrence of ≥ grade 2 RE. These four indicators were included in the nomogram model, and ROC curve analysis showed that the model could properly predict the occurrence of ≥ grade 2 RE (AUC=0.686, 95% CI: 0.585-0.787). The calibration curve indicated that the actually observed values were in good agreement with the predicted RE. Decision curve analysis (DCA) demonstrated satisfactory nomogram positive net returns in most threshold probabilities. Conclusions:PNI before treatment is an independent prognostic factor for patients with CUTESCC who received definitive chemoradiotherapy. The maximum transverse diameter of the lesion, GTV, prescription dose and PNI are the risk factors for ≥ grade 2 RE in this cohort. Establishing a prediction model including these factors has greater predictive value.
