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: Chronic obstructive pulmonary disease (COPD) is a major health concern in northwest China; however, the impact of particulate matter (PM) exposure during sand-dust storms (SDS) remains poorly understood. Therefore, this study aimed to investigate the association between PM exposure on SDS days and COPD hospitalization risk in arid regions. METHODS: Data on daily COPD hospitalizations were collected from 323 hospitals from 2018 to 2022, along with the corresponding air pollutant and meteorological data for each city in Gansu Province. Employing a space-time-stratified case-crossover design and conditional Poisson regression, we analyzed 265,379 COPD hospitalizations. RESULTS: PM exposure during SDS days significantly increased COPD hospitalization risk [relative risk ( RR) for PM _2.5, lag 3:1.028, 95% confidence interval ( CI): 1.021-1.034], particularly among men and the elderly, and during the cold season. The burden of PM exposure on COPD hospitalization was substantially high in Northwest China, especially in the arid and semi-arid regions. CONCLUSION Our findings revealed a positive correlation between PM exposure during SDS episodes and elevated hospitalization rates for COPD in arid and semi-arid zones in China. This highlights the urgency of developing region-specific public health strategies to address adverse respiratory outcomes associated with SDS-related air quality deterioration.

Purpose To establish glucose metabolism patterns of Parkinson's disease(PD)at different periods,and to study the changing pattern of target region of interest(ROI)with the period of time,and then explore the relationship between ROIs and cognitive or motor in different periods.Materials and Methods A total of 42 patients with early-stage PD collected from June 2010 to September 2022 in online data from the markers of Parkinson's progression study which included clinical data,and FDG PET imaging was performed at baseline,12,24,36 and 48 months.The data of 8 healthy volunteers were also obtained from the database,and the time range was the same as that of the above-mentioned PD patients.The longitudinal changes of cerebral glucose metabolism in PD patients and the relationship between PD-associated ROI and movement disorder society-sponsored revision of the unified Parkinson's disease rating scale(MDS-UPDRS)score were evaluated.Results PD was relatively reduced activity located in frontal and parietal association areas and relatively increased activity in the cerebellum,the putamen and the cingulate gyrus.In our study of target ROIs over time,FDG uptake in the caudate nucleus,putamen,pallidum,and cerebellum of patients with PD was initially higher than in the normal group,and subsequently decreased.In contrast,the ROI of PD in the anterior cingulate gyrus,posterior cingulate gyrus,the substantia nigra pars compacta and substantia nigra pars reticulata was initially lower than that in healthy controls and subsequently increased.The putamen,pallidum and caudate nucleus metabolic activity showed a positive correlation in 36 month and MDS-UPDRS scores(r=0.659 5,0.678 7,0.716 7,all P<0.05).The caudate nucleus,putamen and pallidum metabolic activity showed a negative correlation in 24 month and baseline(r=-0.541 8,-0.878 9,-0.887 6,all P<0.05).Conclusion We provide 5-year longitudinal data on changes in 18F-FDG imaging outcomes in early PD.In addition,the glucose metabolic activity of caudate nucleus,putamen and globus pallidus are correlated with MDS-UPDRS scores.

Objective To observe the value of artificial intelligence(AI)models based on non-contrast chest CT for measuring bone mineral density(BMD).Methods Totally 380 subjects who underwent both non-contrast chest CT and quantitative CT(QCT)BMD examination were retrospectively enrolled and divided into training set(n=304)and test set(n=76)at a ratio of 8∶2.The mean BMD of L1-L3 vertebrae were measured based on QCT.Spongy bones of T5-T10 vertebrae were segmented as RO1,radiomics(Rad)features were extracted,and machine learning(ML),Rad and deep learning(DL)models were constructed for classification of osteoporosis(OP)and evaluating BMD,respectively.Receiver operating characteristic curves were drawn,and area under the curves(AUC)were calculated to evaluate the efficacy of each model for classification of OP.Bland-Altman analysis and Pearson correlation analysis were performed to explore the consistency and correlation of each model with QCT for measuring BMD.Results Among ML and Rad models,MLBagging OP and RadBagging-OP had the best performances for classification of OP.In test set,AUC of MLBagging-OP,RadBagging-op and DLOP for classification of OP was 0.943,0.944 and 0.947,respectively,with no significant difference(all P＞0.05).BMD obtained with all the above models had good consistency with those measured with QCT(most of the differences were within the range of(x)±1.96s),which were highly positively correlated(r=0.910-0.974,all P＜0.001).Conclusion AI models based on non-contrast chest CT had high efficacy for classification of OP,and good consistency of BMD measurements were found between AI models and QCT.

Objective To explore the role of ATM/hnRNPK signaling in the adriamycin resistance of acute myeloid leukemia.Methods Expression of ATM was examined in the adriamycin resistant and sensitive leukemia cell strains with Western blot.ATM expression was down-regulated by RNAi and ATM inhibitor in the adriamycin resist-ant cell strains.Expression level of hnRNPK and LC3Ⅰ/Ⅱ was detected by Western blot and adriamycin sensitivity was measured by CCK8 assay before and after modulation of ATM expression.Results ATM was overex-pressed in adriamycin resistant leukemia cell strains.The decreased expression of ATM restored the sensitivity to adriamycin.Expression level of LC3Ⅱ and hnRNPK was consistent with the modulation of ATM expression.Conclusions The ATM/hnRNPK signaling pathway may play a role in the occurrence of adriamycin resistance in acute myeloid leukemia by regulating autophagy.

Objective To explore the cut-off value of three dimensional(3D)vena contracta area(VCA)in diagnosing severe tricuspid regrugitation(TR)under different etiologies and its accuracy and practicality in clinical application.Methods From Mar 2019 to May 2021,ninety-two patients with confirmed TR underwent two dimensional(2D)and 3D transthoracic echocardiography.The correlation and consistency between 3D VCA 3D calculated based on the proximal isokinetic surface area(PISA)effective regurgitant orifice area(EROA)was calculated.Comprehensive 2D multi-parameter method was used as a reference method to calculate the cut-off value of the diagnosis of severe TR.Results A total of 85 patients were ultimately included.3D VCA and 3D PISA EROA had similar and acceptable correlations in both primary TR and secondary TR(primary TR:r=0.831,P<0.01;secondary TR:r=0.806,P<0.01).Bland-Altman analysis showed that 3D VCA overestimated TR compared with 3D PISA EROA(62%overestimated in the total patient population,51%overestimated in primary TR,and 74%overestimated in secondary TR).In secondary TR,the cut-off value of 3D VCA for diagnosing severe TR was 0.45 cm2(sensitivity 89%,specificity 82%);combining clinical symptoms,positive 2D PISA EROA results and 3D VCA results for severe TR,the chi-square value was higher than those only included clinical symptoms or incorporated clinical symptoms and positive 2D PISA EROA results(42.168 vs.26.059 and 16.759,P<0.01).Conclusion 3D VCA would overestimate TR,and had high and incremental diagnostic value for evaluating severe TR in secondary TR.

Objective To investigate anxious and depressive emotions in patients underwent cervical cancer surgery and to analyze its influencing factors.Methods A total of 304 patients who underwent primary cervical cancer surgery in Obstetrics and Gynecology Hospital,Fudan University from Oct 2018 to Jun 2021,were recruited to evaluate the clinical effect based on cervical cancer-patient reported outcome 137 scale(CC-PRO137 scale).This study focused on dimensions of depressive and anxious emotions within this scale and explored their influencing factors.Results The average scores of their depressive and anxious emotions within half a year after surgery were 4.141±0.798 and 4.020±0.616,respectively;and the average scores of depressive and anxious emotions more than one year after surgery were 4.250±0.802 and 4.097±0.613,respectively.By using statistical methods including analysis of variance and t test,it was found that there were statistically significant differences in the scores of depression and anxiety among cervical cancer patients under different postoperative adjuvant treatments and at different postoperative time points(P<0.05).However,there were no statistically significant differences in the scores of depression and anxiety among patients with different ages,surgical methods,and clinical stages of cervical cancer(P>0.05).Conclusion Patients underwent cervical cancer surgery may suffer varying degree of depressive and anxious emotions,and the main influencing factors are different adjuvant treatments and the length of time for postsurgical recovery.Medical practitioners should strengthen comfort and care for patients with cervical cancer,especially those who receive chemotherapy and radiotherapy treatments and are in the primary stage after the surgery.Formulating positive intervention measures can effectively reduce the psychological pain of patients and safeguard their physical and mental health.

OBJECTIVE To investigate the effects of sacubitril/valsartan on renal function in patients with primary hypertension. METHODS A retrospective study was conducted among patients with primary hypertension who were admitted to PLA Strategic Support Force Characteristic Medical Center from January 2018 to June 2023. Based on their medication， they were divided into two groups： sacubitril/valsartan group and valsartan group. Propensity score matching was used to match baseline data between the two groups. Patients were treated with antihypertensive drugs based on improving their lifestyle. Sacubitril/valsartan group additionally received oral administration of 200 mg Sacubitril/valsartan tablets once daily， while valsartan group additionally received oral administration of 80 mg Valsartan capsules once daily. The increase amplitude of serum creatinine from baseline， the proportion of patients with elevated serum creatinine ＞30%-50% or ＞50%， and the proportion of patients with hyperkalemia （serum potassium ≥5.5 mmol/L） were compared between two groups at 2 months and 6 months after treatment. The trends of changes in serum creatinine， serum potassium and estimated glomerular filtration rate （eGFR） were compared between the two groups before treatment （at baseline）， 2 months and 6 months after treatment. RESULTS After propensity score matching， there were 62 patients in sacubitril/valsartan group and 61 patients in valsartan group； there were no significant differences in baseline characteristics between the two groups before treatment （P＞0.05）， indicating comparability. After 6 months of treatment， the increase of serum creatinine in the sacubitril/valsartan group was significantly lower than that in the valsartan group （P＝0.003）； the proportion of patients with elevated serum creatinine ＞30%-50% in the sacubitril/valsartan group was significantly lower than that in the valsartan group （P＝0.045）. None of the patients experienced hyperkalemia events after 2 months and 6 months of treatment. Repeated measures analysis of variance showed significantly statistical differences in serum creatinine and eGFR between the two groups within 6 months of treatment （P＜0.001）. Patients taking valsartan experienced a continuous increase in serum creatinine levels and a decrease in eGFR， while patients taking sacubitril/valsartan showed a first increase and then a decrease in serum creatinine levels， and a first decrease and then an increase in eGFR with a prolonged duration of medication. CONCLUSIONS Sacubitril/valsartan can delay or even reverse the decline in renal function levels， and limit the deterioration of renal function in patients with primary hypertension， without increasing the risk of hyperkalemia.

【Objective】 To analyze the correlation between the distribution interval of minipool nucleic acid testing(NAT) positive CT value and the resolution rate, so as to improve the retest model and reduce residual risk of blood transfusion. 【Methods】 The resolution testing results by Cobas S201 system of our blood center from January 2017 to December 2021 were retrospective analyzed, and the retest model was developed based on the distribution interval of CT values. For minipool NAT HBV positive samples from March 2022 to March 2023, synchronous detection was conducted by Cobas S201 and Panther detection system, and the detection results were statistically analyzed. 【Results】 From 2017 to 2021, 474 were minipool NAT positive, among which 324 were HBV positive, accounting for 68.35%. From 2017 to 2020, the proportion of HBV positive per year was significantly higher than that of HCV and HIV(P<0.05). In resolution testing, 167 were HBV repeatable positive and 157 were HBV non-repeatable positive, accounting for 51.54% and 48.46% of HBV minipool NAT positive. HBV repeatable positive samples were with three intervals: CT value≤36, 3640, with the resolution rate at 95.8%, 56.5% and 14.8% respectively(P<0.05). The proportion of 3640, 36

Objective: To analyze the epidemic characteristics and drug resistance of pulmonary tuberculosis among the floating population in Beijing and to provide a scientific basis for formulating strategies for the prevention and control of tuberculosis among the floating population. Methods: Data of tuberculosis patients who were positive for Mycobacterium tuberculosis culture was collected from 16 districts and one municipal institution of tuberculosis control and prevention in Beijing in 2019. The strain samples were tested for drug sensitivity by the proportional method. According to household registration location, patients were divided into the floating population and Beijing registration. SPSS 19.0 software analyzed tuberculosis patients' epidemic characteristics and drug resistance in the floating population. Results: In 2019, there were 1 171 culture-positive tuberculosis patients in Beijing, among the floating population, 593 (50.64%) patients were identified, with a male-to-female sex ratio of 2.2∶1 (409∶184). Compared to patients under household registration as Beijing residents, a higher proportion of young adults aged 20-39 years (65.09%,386/593) were noticed, with 55.65% (330/593) reported from the urban areas and 96.80% (574/593) were reported the first time. The differences were statistically significant (all P<0.05). After completing the drug sensitivity test, 37 cases were with multiple drug-resistant tuberculosis, accounting for 6.24% (37/593). The rates of isoniazid resistance (42.11%,8/19) and multidrug resistance (21.05%,4/19) in floating population patients after retreatment were significantly higher than those in newly treated patients (11.67%, 67/574 and 5.75%, 33/574), and the differences were statistically significant (all P<0.05). Conclusions: Most patients with tuberculosis in the floating population in Beijing in 2019 were young males aged 20-39 years. The reporting areas were urban areas and the newly treated patients mainly. The patients with tuberculosis in the re-treated floating population were more likely to suffer from multidrug and drug resistance, which should be taken as the key population for prevention and control.
