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 analyze the clinical efficacy of vascular resection and reconstruction during radical resection in patients with hilar cholangiocarcinoma.Methods:A retrospective analysis was conducted on the clinical data of 151 patients with hilar cholangiocarcinoma who underwent radical resection in the Department of Hepatobiliary and Pancreatic Surgery at the First Affiliated Hospital of Anhui Medical University from April 2018 to April 2025. Among them, there were 91 males and 60 females, with an age of (65.4±10.5) years. According to whether radical resection of hilar cholangiocarcinoma was combined with vascular resection, the patients were divided into the vascular resection group ( n=19) and the control group ( n=132). Postoperative complications such as bleeding, biliary fistula, and thrombosis were recorded, along with intraoperative blood loss, R 0 resection rate, perioperative mortality, and recurrence rate at six months postoperatively. Results:The preoperative bilirubin reduction and intraoperative blood loss in the vascular resection group were 6 (31.6) and 200 (200, 200) ml, respectively, while those in the control group were 45 (34.1) and 200 (100, 200) ml, respectively. There were no statistically significant differences between the two groups (all P>0.05). The combined liver resection, Billroth operation type Ⅰ-Ⅱ, and operation time in the vascular resection group were 18 (94.7), 1 (5.3), and 420 (377.5, 512.5) min, respectively, while those in the control group were 79 (59.8), 38 (28.8), and 322.5 (260, 410) min, respectively. There were statistically significant differences between the two groups (all P<0.05). The R 0 resection, perioperative mortality rate, postoperative bleeding, postoperative biliary fistula, postoperative thrombosis, postoperative pathology (adenocarcinoma), and recurrence rate at 6 months after surgery in the vascular resection group were 16 (84.2), 2 (10.5), 2 (10.5), 3 (15.8), 1 (5.3), 18 (94.7), and 1 (5.9), respectively, while those in the control group were 103 (78.0), 5 (3.8), 5 (3.8), 25 (18.9), 2 (1.5), 121 (91.7), and 6 (4.7), respectively. There were no statistically significant differences between the two groups (all P>0.05). The postoperative hospital stay, alanine aminotransferase on the 1st and 3rd day after surgery, and postoperative liver failure in the vascular resection group were 18 (13.5, 21.5) days, 619 (305.4, 1 634.0) U/L, and 1 (5.3), respectively, while those in the control group were 14 (11, 18), 254.5 (139.3, 468.3) U/L, and 3 (2.3), respectively. There were statistically significant differences between the two groups (all P<0.05). Conclusion:Vascular resection and reconstruction during radical resection of hilar cholangiocarcinoma in patients has certain safety and efficacy.

Chronic pain has emerged as a prevalent medical challenge in contemporary society.Patients suffering from chronic pain frequently develop comorbid psychological disorders,including anxiety,depression,post-traumatic stress disorder,and various psychiatric syndromes.These psychological complications not only affect patients' pain perception and responses,but may also constitute critical obstacles during pain management interventions.Acupuncture is a long-established clinical practice that has demonstrated remarkable efficacy in alleviating diverse pain types and has shown favorable therapeutic outcomes in ameliorating emotional disturbances such as anxiety and depression.The precise mechanisms underlying acupuncture-induced analgesia and anxiolytic effects,however,remain to be fully elucidated.In this context,it is essential to establish suitable and stable animal models to allow in-depth investigations into the pathogenesis of pain-related emotional disorders and the mechanistic foundations of acupuncture.This article presents a comprehensive review of recent literature regarding the selection of experimental animals,model-establishment method ologies,and behavioral-assessment paradigms pertaining to animal model platforms of chronic pain with comorbid anxiety.We also provide an in-depth discussion of research advancements regarding acupuncture intervention parameters,including needling techniques,acupoint selection,treatment duration,and efficacy evaluation within these animal models.This review proposes comprehensive and reference strategies for constructing preclinical animal models to investigate the mechanisms of acupuncture in managing chronic pain with comorbid anxiety,thus supporting scientific advancements in related research fields.

Objective Using female mice to investigate the reparative effects of human umbilical cord mesenchymal stem cells on radiation-induced ovarian injury. Methods Mice were randomly divided into three groups: a blank control group, a radiation model group, and a cell therapy group. Mice in the radiation model group and the cell therapy group received a single whole-body irradiation of 5 Gy X-rays. Within 2 hours post-irradiation, mice in the cell therapy group underwent ovarian transplantation of UC-MSCs. On days 1, 7, and 14 post-irradiation, body weight was measured, ovarian index was calculated, histopathological changes in ovarian tissue were examined, serum levels of reproductive hormones (follicle-stimulating hormone, anti-Müllerian hormone, and estradiol) were determined, and the colonization of implanted UC-MSCs in the mice was observed. Results On days 1, 7, and 14 post-irradiation, both the cell therapy group and the radiation model group showed decreased body weight compared to the blank control group (P < 0.05). On day 1 post-irradiation compared to day 1 pre-irradiation within the same group, the radiation model group exhibited a greater decrease in body weight than the cell therapy group (P < 0.05). On days 1, 7, and 14 post-irradiation, the ovarian index decreased in both the radiation model group and the cell therapy group compared to the blank control group (P < 0.05). On days 7 and 14 post-irradiation, the ovarian index in the cell therapy group was significantly higher than that in the radiation model group (P < 0.05). Ovarian tissue in the radiation model group exhibited atrophy and a reduction in the number of follicles at all stages. In contrast, follicles in the cell therapy group were large and abundant. On days 1, 7, and 14 post-irradiation, serum follicle-stimulating hormone levels in the cell therapy group were lower than those in the radiation model group, while anti-Müllerian hormone and estradiol levels were higher than those in the radiation model group (P < 0.01). In vivo fluorescence imaging demonstrated that UC-MSCs successfully colonized the ovarian tissue on days 1, 7, and 14 after transplantation. Conclusion UC-MSCs exert a repair effect on radiation-induced ovarian injury in mice.

Objective To explore the role and mechanism of warm malate ringer's solution(MR)in resuscitation of the lethal triad caused by severe trauma.Methods A rat model of severe trauma was established in SPF-grade SD rats(half male and half female,weighing 200～220 g)using combined multiple injuries and hemorrhagic shock,and the rats were randomly divided into 8 groups(n=8):Sham group,only arterial and venous catheterization;Trauma(Tra)groups with different time points(10,30,60,90,120,180 min)and a Trauma group that were observed without any treatment for 180 min after model establishment.The changes of activated clotting time(ACT),reaction time(R),maximum amplitude(MA),and rate of blood clot formation(Angle)at different time points were detected by using thromboelastography,and tail bleeding,core body temperature and arterial blood gas parameters,were also observed and detected.The plasma von Willebrand Factor(vWF)level,mitochondrial respiratory control ratio in pulmonary venous endothelium,and expression levels of vascular endothelial cadherin(VE-Cadherin),peroxisome proliferator activating receptor gamma coactivator 1α(PGC1α),dynamin-related protein 1(Drp1),p-Drp1,and mitofusin 2(Mfn2)were detected to evaluate the vascular endothelial injury and mitochondrial dysfunction.Another group of SD rats were randomly divided into severe trauma group(no treatment for 180 min after injury),and MR solution at room temperature and at 37 ℃ groups.MR solution at room temperature or at 37 ℃ was given to the rats using a medical blood transfusion apparatus at 60 min post-trauma.Above indicators were observed and detected to investigate the resuscitation effect of the MR solution.Results Compared with the Sham group,the severely traumatic rats at 180 min after injury had significantly prolonged ACT and R values(P＜0.05),shortened MA and decreased Angle values(P＜0.05),extended tail bleeding time(P＜0.05),lower partial pressure of carbon dioxide(PCO2)and HCO3-and base excess(BE)levels(P＜0.05),and continuously increasing K+(P＜0.05)and decreasing Na+(P＜0.05)and Ca2+levels(P＜0.05).Additionally,plasma vWF level(P＜0.05)and protein levels of VE-cadherin,PGC1α and Mfn2 in pulmonary vein endothelium were significantly reduced(P＜0.05),the expression of p-Drp1 was enhanced and the mitochondrial respiration control rate was declined in the rats at 180 min after injury(P＜0.05).MR solution resuscitation shortened tail bleeding time(P＜0.05),increased core body temperature(P＜0.05),elevated plasma vWF level(P＜0.05),increased protein levels of VE-cadherin,PGC1α and Mfn2(P＜0.05),and decreased that of p-Drp1 protein expression(P＜0.05)when compared with the rats at 180 min after severe traumatic injury.The above effects were more significant in the rats infused with the solution at 37 ℃ than those at room temperature.Conclusion Warm MR solution significantly improves the lethal triad in rats after severe trauma,which may be associated with its improving mitochondrial function and attenuating vascular endothelial damage.

AIM:This study investigated the potential mechanism of acupuncture regulating adenosine A1 re-ceptor(ADORA1)in the mouse caudate putamen(CPu)to improve neuroplasticity and alleviate inflammatory pain.METHODS:Male C57BL/6 mice were randomly divided into five groups,namely,saline,complete Freund's adjuvant(CFA),acupuncture(MA),acupuncture+ADORA1 shRNA(MA+shRNA),and acupuncture+negative shRNA(MA+NCshRNA)groups.Twenty-one days before modeling,the mice in the MA+shRNA and MA+NCshRNA groups were in-jected with ADORA1 shRNA and control virus into the CPu.Modeling was performed 21 d later by injection of CFA into the right plantar skin of mice in the model and acupuncture groups to induce adjuvant-mediated arthritis.On day 2 after modeling,mice in the acupuncture groups received acupuncture at bilateral"Zusanli"points,30 min per session,once a day,for a total of 7 days.The paw thermal radiation pain threshold was used as an indicator of the effects on pain in the mice.Changes in the protein levels of ADORA1,synaptophysin(SYP),synapsin(SYN)I,SYN II,and brain-derived neurotrophic factor(BDNF)in the CPu were assessed by Western blot,and transmission electron microscopy was used to examine the dendritic structure and synaptic ultrastructure of neurons within the CPu.RESULTS:(1)Compared with the saline group,CFA modeling significantly reduced the thermal radiation pain threshold in mice(P<0.01),as well as the protein levels of ADORA1(P<0.01).Compared with the CFA group,the thermal pain threshold in the MA group in-creased between days 1 and 7 of acupuncture(P<0.05 or P<0.01),and ADORA1 protein levels increased(P<0.01).(2)Compared with the saline group,SYN I,SYN II,and BDNF protein levels were increased in the CFA group(P<0.05 or P<0.01),while relative to the CFA group,the levels of SYN I,SYN II,and BDNF were reduced in the acupuncture group(P<0.05 or P<0.01).No significant changes in SYP protein levels were observed in any of the groups.(3)Golgi staining and Sholl analysis showed that compared with the saline group,there were reductions in the total dendritic length and number of intersection points in the CFA group,while the dendritic spine density increased(P<0.05).Relative to the CFA group,the total dendritic length and the number of intersection points were increased in the MA group,while the dendritic spine density decreased(P<0.05).(4)Transmission electron microscopy revealed that compared with the Sa-line group,the synaptic clefts were narrower in the CFA group,while the density of synaptic vesicles in the presynaptic membrane was increased.Compared with the CFA group,synaptic clefts in the MA group were wider,and synaptic vesi-cle densities in the presynaptic membrane were reduced.(5)Twenty-one days after viral transfection,the thermal pain threshold in the MA and MA+NCshRNA groups increased from day 1 to day 7 of acupuncture relative to the CFA and MA+shRNA groups(P<0.05 or P<0.01),while the expression of ADORA1 was increased in both the MA and MA+NCshRNA groups(P<0.05 or P<0.01).(6)Compared with the CFA and MA+shRNA groups,the protein expression of SYN II and BDNF in the MA and MA+NCshRNA groups was reduced(P<0.05 or P<0.01).No significant changes in SYN I protein were observed in any of the groups.CONCLUSION:Acupuncture on Zusanli point can alleviate chronic pain in CFA-treated mice,potentially mediated by up-regulation of ADORA1 expression in the CPu brain region,thereby improving neuroplasticity.

Objective:To establish an ultrasound radiomics model by integrating clinical, pathological, and conventional ultrasound features with radiomics characteristics, and to explore its clinical value in predicting endocrine resistance in hormone receptor(HR)-positive breast cancer.Methods:A retrospective analysis was performed on 478 patients with HR-positive breast cancer from January 2017 to December 2021 in the Second Affiliated Hospital of Harbin Medical University, of which 430 were resistant and 48 were sensitive. The clinical, pathological and immunohistochemical data and ultrasound images were collected.Firstly, the propensity score was used to process and match the data. Secondly, Logistic regression was used to screen clinical, pathological, and conventional ultrasound features associated with endocrine resistance. Then, PyRadiomics was used to extract the radiomic features of grayscale ultrasound images, and a series of methods such as Lasso regression were used to screen the radiomic features related to endocrine resistance. Seven machine learning methods such as random forest were used to build a radiomics model. Finally, clinical, pathological and ultrasound features were added to establish a clinical pathological model, a clinical pathological ultrasound model, a clinical pathological radiomics model and a combined model of the four features, and the model effectiveness was evaluated.Results:①Propensity score matching: 96 patients were matched, including 48 patients in the drug-resistant group and 48 patients in the sensitive group. ②Screening clinical pathological conventional ultrasound features related to endocrine resistance: lymph node metastasis, tumor diameter, posterior echo attenuation, and growth orientation were independent predictors of endocrine resistance (all P<0.05). ③Screening radiomics features related to endocrine resistance: 18 features such as Dependence Entropy. ④Establishing radiomics model: the machine learning model of random forest method (AUC=0.80) performed best. ⑤Radiomics model integrating clinical, pathological and conventional ultrasound features: the AUC of the clinical pathological model was 0.70, the AUC of the clinical pathological ultrasound model was 0.78, the AUC of the clinical pathological radiomics model was 0.82, and the AUC of the combined model was 0.86. Conclusions:The radiomics model established by the random forest method performs best in predicting endocrine resistance in HR-positive breast cancer. The model that integrates multiple features performs best in assessing endocrine resistance.which is expected to provide an objective basis for clinicians to predict endocrine resistance in HR-positive breast cancer.
