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.

With the gradual development and popularization of extracorporeal membrane oxygenation (ECMO) in China, some prefecture-level medical institutions in China have carried out and formed their own pre-hospital extracorporeal cardiopulmonary resuscitation (ECPR) model. Although the development levels of various prefecture-level cities are uneven and the start times vary, at present, the prefecture-level hospitals in China generally go through the development process of ECMO-in-hospital ECPR-pre-hospital ECPR-professional medical recovery center. Among them, in-hospital ECPR has the advantages of timely resuscitation, guaranteed quality of resuscitation, and fast activation speed of the ECPR team, and currently has a high success rate, with a low proportion of patients with neurological complications. However, pre-hospital ECPR is more challenging, requiring the coordination between pre-hospital and in-hospital emergency forces, multidisciplinary cooperation, and the quality of resuscitation before ECPR cannot be fully guaranteed, the long duration of patient's low perfusion, and other factors make the survival rate of patients without neurological damage obviously lower than that of in-hospital ECPR. China has a large population base, and comprehensive domestic and foreign data show that there should be no less than several million cases of out-of-hospital cardiac arrest under the age of 60 every year, so there is much to be done to improve the survival rate of pre-hospital ECPR. Pre-hospital ECPR is a project of concentrated resources and technology, which has high requirements for the multidisciplinary diagnosis and treatment capabilities of medical institutions. The optimization of the implementation process of in-hospital and pre-hospital ECPR teams, the advancement of the timing of ECPR intervention, the selection of patients, the support and construction of multidisciplinary diagnosis and treatment capabilities after ECPR, and the management of related complications and risk factors are closely related to the prognosis of ECPR patients. The recoverability of the brain and heart is currently the key factor restricting the further improvement of the survival rate of patients after ECPR. Considering that the recovery of neurological function mainly depends on the duration of the early low perfusion, the in-hospital treatment after the implementation of ECPR is mainly the low-temperature brain protection strategy, the effect of which is still controversial, so the recovery of cardiac function is the key that seriously restricts the survival of patients after ECPR in addition to neurological prognosis. The recoverability of the heart after ECPR can be implemented from multiple angles: the research on pathophysiological issues such as the matching of the heart itself after the implementation of ECPR, and the matching between the heart and ECMO, and the proposal of corresponding countermeasures will help to improve the survival rate of patients after ECPR. The large population and the potential salvageable population make the development of ECPR technology in China's tertiary hospitals urgent and necessary, with challenges and opportunities coexisting.

Objective:To analyze the epidemic trend of influenza-like illness（ILI）cases，etiological detection results，and the evolution of the hemagglutinin（HA）gene of the predominant strains in Hanzhong City，Shaanxi Province during the 2018-2024 influenza seasons.Methods:ILI sentinel surveillance data and network laboratory test results during the 2018-2024 influenza seasons in Hanzhong City，Shaanxi Province were collected for descriptive analysis. The HA gene sequences of 25 predominant strains were obtained through whole-genome deep sequencing method，and then compared with the vaccine strains recommended by the World Health Organization in the same period to analyze the evolution of the virus.Results:A total of 37 770 cases of ILI were reported in Hanzhong City during the 2018-2024 influenza seasons，and the proportion of total ILI cases（ILI%）was 2.87%（37 770/1 316 009）. The epidemic trend of ILI showed an obvious epidemic peak in winter and spring（from December of the current year to March of the following year）. The specimens with the highest positive rate were of type A（H3N2）（39.12%，365/933），and the predominant epidemic strains in each influenza season alternated among A（H1N1）pdm09（in the 2018-2019 and 2022-2023 influenza seasons），A（H3N2）（in the 2019-2020 and 2023-2024 influenza seasons）and B（Victoria）（in the 2021-2022 influenza season）. The phylogenetic relationship gradually became more distant over time across different influenza seasons. Among them，the epidemic strains of A（H1N1）pdm09 belonged to the 6B.1 clade，and the evolution mainly occurred in the Sa and Sb regions of the HA epitope. Meanwhile，the epidemic strains of A（H3N2）belonged to the 3C clade，and the evolution mainly took place in the A，B and C regions of the HA epitope. The strains of the B（Victoria）lineage belonged to the V1a.3a.2 clade，and the evolution mainly occurred in the 120-loop，150-loop，and 190-helix regions of the HA epitope.Conclusions:The influenza epidemic in Hanzhong City has obvious seasonality，and the amino acids of the epidemic strains have shown a certain degree of variation over the years. In future prevention and control work，influenza surveillance should be continuously strengthened，and the change trend of the predominant circulating strains should be closely monitored.

Objective:To explore the molecular mechanism of miR-4508 regulating the inflammatory response of human bronchial epithelial cells induced by representative chrysotile asbestos.Methods:The chrysotile asbestos was ground into ultrafine dust using a horizontal planetary instrument, and human bronchial epithelium (16HBE) cells were taken as the object of infection. Cell survival rate was detected by cell counting kit-8 method, cytotoxicity was detected by lactate dehydrogenase (LDH) kit. The released of inflammatory factor IL-6 was detected by electrochemical luminescence. The released inflammatory factor IL-8 was detected by enzyme-linked immunosorbent assay. The expression level of miR-4508 was screened and verified by reverse transcription-quantitative real-time polymerase chain reaction. After 16HBE cells were treated with AKT inhibitor MK2206, the phosphorylation levels of AKT and PTEN were detected by western blot. The expression levels of AKT and PTEN and the contents of IL-6 and IL-8 were detected in miR-4508 overexpression and interference experiments.Results:With the increase of chrysotile asbestos exposure concentration, the cell survival rate decreased in a concentration-dependent manner, and the LDH content gradually increased. The secretion of IL-6 and IL-8 in chrysotile 25, 50 and 75 μg/ml groups were (325.92±8.61) pg/ml, (331.51±4.96) pg/ml, (378.74±13.77) pg/ml, and (94.95±3.11) pg/ml, (357.60±1.80) pg/ml, (537.19±3.11) pg/ml, respectively, while the group with 0 μg/ml chrysotile was (95.85±1.20) pg/ml and (7.81±0.00) pg/ml ( P＜0.05). In addition, chrysotile asbestos exposure to 16HBE could induce the high expression of miR-4508 . After pretreatment with MK2206, the phosphorylation levels of AKT and PTEN were decreased, the contents of IL-6 and IL-8 were significantly decreased, and the expression level of miR-4508 was significantly reduced. Overexpression of miR-4508 significantly increased the expressions of AKT and PTEN, and the contents of IL-6 and IL-8 ( P＜0.01). After interfering with miR-4508, the expressions of AKT and PTEN were significantly decreased, and the contents of IL-6 and IL-8 were significantly decreased ( P＜0.01). Conclusions:Chrysotile asbestos can induce the inflammatory response of 16HBE cells and up-regulate the expression level of miR-4508. The up-regulation of miR-4508 promotes the 16HBE inflammatory response induced by chrysotile asbestos through the PI3K/AKT pathway.

Objective:To develop and validate the Intimate Relationships Happiness Questionnaire(IRHQ).Methods:Firstly,interviews were conducted with 20 participants,investigation were conducted with 100 partici-pants,and vocabulary scoring were conducted with 100 participants formed the originally items.Secondly,801 par-ticipants were recruited to finished the initial scale for items analysis and exploratory factor analysis.Thirdly,480 participants were conducted with the IRHQ,Satisfaction With Life Scale(SLS),Subjective Authentic-Durable Hap-piness Scale(SA-DHS),Chinese Happiness Inventory(CHI)and Marital Happiness Scale(MHS)for confirmatory factor analysis,criterion-related validity and internal consistency analysis.Finally,100 participants were assessed with IRHQ after 2 weeks for test-retest reliability.Results:After items analysis and exploratory factor analysis,29 i-tems were selected as the final scale with a total of four factors that accounted for 63.76％of the variance in all for IRHQ,4 factors including body harmony,mental harmony,fitting-value and sexual relationship satisfac-tion.Confirmatory factor analysis indicated that the four-factor model had a goof structural fit(x2/df=2.89,P＜0.001,TLI=0.93,CFI=0.94,RMSEA=0.04).The scores of IRHQ was positively correlated with the scores of SLS,SA-DHS,CHI and MHS(ICC=0.27-0.72,Ps＜0.001).The internal consistency reliabilities of the total score of the scale and the score of the 4 factors were 0.74,0.73,0.72,0.78 and 0.90.The retest reliabilities were 0.87,0.83,0.88,0.88 and 0.90.Conclusion:The Intimate Relationships Happiness Questionnaire meetsthe psy-chometric standard and could be used to assess the intimate relationship well-being.

The gut microbiota plays a pivotal role in the immunomodulatory and protumorigenic microenviron-ment of colorectal cancer(CRC).However,the effect of ginsenoside Rk3(Rk3)on CRC and gut microbiota remains unclear.Therefore,the purpose of this study is to explore the potential effect of Rk3 on CRC from the perspective of gut microbiota and immune regulation.Our results reveal that treatment with Rk3 significantly suppresses the formation of colon tumors,repairs intestinal barrier damage,and regulates the gut microbiota imbalance caused by CRC,including enrichment of probiotics such as Akkermansia muciniphila and Barnesiella intestinihominis,and clearance of pathogenic Desulfovibrio.Subsequent metabolomics data demonstrate that Rk3 can modulate the metabolism of amino acids and bile acids,particularly by upregulating glutamine,which has the potential to regulate the immune response.Furthermore,we elucidate the regulatory effects of Rk3 on chemokines and inflammatory factors associated with group 3 innate lymphoid cells(ILC3s)and T helper 17(Th17)signaling pathways,which inhibits the hyperactivation of the Janus kinase-signal transducer and activator of transcription 3(JAK-STAT3)signaling pathway.These results indicate that Rk3 modulates gut microbiota,regulates ILC3s immune response,and inhibits the JAK-STAT3 signaling pathway to suppress the development of colon tumors.More importantly,the results of fecal microbiota transplantation suggest that the inhibitory effect of Rk3 on colon tumors and its regulation of ILC3 immune responses are mediated by the gut microbiota.In summary,these findings emphasize that Rk3 can be utilized as a regulator of the gut microbiota for the prevention and treatment of CRC.

Objective:To investigate the clinical characteristics and potential predisposing factors of the external cervical resorption(ECR).Methods:22 ECR cases with 38 affected teeth from 2016 to 2022 were retrospectively reviwed.Descriptive analysis combined with single factor analysis was used to study the clinical characteristics and influencing factors of ECR.Results:Maxillary anterior teeth(34.2％)were the most affected by ECR.Univariate analysis showed that ECR was more commonly noted in teeth without percussion pain and palpation pain,the probing depth of the periodontal pocket was greater than 3mm,with pulp activity reaction,without forma-tion of abscess and/or sinus tract,and without periapical lesions.There were statistically significant differences in percussion tender-ness,palpation tenderness and probing depth among the different Heithersary stages(P＜0.05).In the advanced cases,deep periodon-tal pockets and abscess formation were observed.The most common related dental factors of ECR were orthodontic treatment(15.87％)and dental traumatic injury(28.57％).Conclusion:ECR affected teeth often lack of clinical signs and symptoms.Radiology is the key to early diagnosis.

Interferon regulatory factor 1(IRF-1)is a member of the IRF family.It is the first transcription factor to be identified that could bind to the interferon-stimulated response element(ISRE)on the target gene and displays crucial roles in the interferon-induced signals and pathways.IRF-1,as an important medium,has all of the advantages of full cell cycle regulation,cell death signaling transduction,and reinforcing immune surveillance,which are well documented.Current studies indicate that IRF-1 is of vital importance to the occurrence and evolution of multifarious liver diseases,including but not limited to inhibiting the replication of the hepatitis virus(A/B/C/E),alleviating the progression of liver fibrosis,and aggravating hepatic ischemia-reperfusion injury(HIRI).The tumor suppression of IRF-1 is related to the clinical characteristics of liver cancer patients,which makes it a potential indicator for predicting the prognosis and recurrence of liver cancer;additionally,the latest studies have revealed other effects of IRF-1 such as protection against alcoholic/non-alcoholic fatty liver disease(AFLD/NAFLD),cholangiocarcinoma suppression,and uncommon traits in other liver diseases that had previously received little attention.Intriguingly,several compounds and drugs have featured a protective function in specific liver disease models in which there is significant involvement of the IRF-1 signal.In this paper,we hope to propose a prospective research basis upon which to help decipher translational medicine applications of IRF-1 in liver disease treatment.
