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 explore the assocation of the family environment and depressive symptoms among primary and middle school students, so as to provide suggestions for further maximizing the utility of family environment in the growth of primary and secondary school students, as well as prevention and intervention of depressive symptoms among children and adolescents. Methods: From June to July 2024, through a multistage cluster random sampling method, 8 800 primary and middle school students aged 10 to 18 from 36 schools in 3 cities (Datong, Lvliang, Linfen) in Shanxi Province. A self designed questionnaire was used to conduct a family environment survey, including family socioeconomic conditions, family structure, family parenting behavior, family member health behavior, etc; and the depression symptoms of primary and secondary school students were investigated by Patient Health Questionnaire-9. The χ 2 test and binary Logistic regression to method were used to analyze the association of the family environment with depressive symptoms among primary and secondary school students, and to analyze gender and urban-rural heterogeneity in this association. Results: The detection rate of depressive symptoms among primary and middle school students was 46.7% ( n = 4 111 ). Among them, the detection rates of depressive symptoms for male and female students were 45.7% and 47.7% respectively, and the detection rates for rural and urban students were 48.0% and 44.9% respectively. The results of binary Logistic regression model showed that in the family environment, factors such as the father s education level (junior high school: OR =0.84), self assessed family socio economic status (average: OR =0.78, good: OR =0.80), parental support and understanding (yes: OR = 0.55 ), family atmosphere (harmonious: OR =0.66), living arrangement (living only with father or mother: OR =1.31, living with parents and grandparents: OR =1.19), and family rearing style (combining punishment and reward: OR =1.42, punishment only: OR =1.25) were related to depressive symptoms in primary and middle school students in Shanxi Province ( P <0.05). From the perspective of gender heterogeneity, the living arrangement (living only with father or mother: OR =1.67, others: OR =1.67) had a statistically significant association with depressive symptoms in male students ( P <0.05). From the perspective of urban rural heterogeneity, the living arrangement (living only with father or mother: OR =1.38) had a statistically significant association with depressive symptoms in rural primary and middle school students ( P <0.05). Conclusions The family environment has an important impact on depressive symptoms in primary and middle school students. Family functioning should be fully exerted to prevent depressive symptoms in primary and middle school students.

Objective:To analyze the effect of perineural invasion(PNI)on immune cell infiltration in pancreatic ductal adenocarcinoma(PDAC)by the CIBERSORT deconvolution algorithm.Methods:The pancreatic cancer patients from the dataset GSE102238 were re-evaluated for the severity of PNI.And then the high and low PNI subgroups were subjected to immune scoring and immune cell infiltration analysis using the ESTIMATE and CIBERSORT algorithms to find immune cell subgroups associated with PNI.Finally,the results were validated by tissue microarrays.Results:Twenty-five cases were selected from 50 pancreatic cancer specimens for PNI reassessment and then divided into two high and low groups.Compared to the low PNI group,specimens from patients in the high group showed significantly less CD8+T-cell infiltration(P<0.05)and significantly more resting memory CD4+T-cells and M0 macrophages(P<0.05).Significantly reduced CD8+T cells(P<0.01)and slightly increased CD4+T cells(P<0.05)were confirmed in the patients with the high PNI using tissue microarrays.Meanwhile,macrophages significantly increased in the high PNI group(P<0.001).Conclusion:High PNI in PDAC inhibits infiltration of CD8+T cells which promote the infiltration of macrophages.

ObjectiveTo investigate the association of lipid ratios with diabetes and pre-diabetes in residents aged 35-75 years in Changzhou City. MethodsA multistage whole-group random sampling method was used to survey permanent residents aged 35-75 years in Tianning and Wujin districts of Changzhou City， and the study data were obtained by questionnaires， physical examination and laboratory tests. The relationship between lipid ratios and diabetes and pre-diabetes was analyzed by dichotomous logistic regression method. ResultsThe prevalence of diabetes in the surveyed population in Changzhou was 18.69%， and the prevalence of pre-diabetes was 10.53%. In the total population， the risk of pre-diabetes was significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 68%， 93% and 38%， respectively； the risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. The risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. All three lipid ratios increased in women compared to men， leading to a stronger association with increased risk of diabetes and pre-diabetes. ConclusionLipid ratios TC/HDL-C， TG/HDL-C， and LDL-C/HDL-C were correlated with the risk of diabetes and pre-diabetes in people aged 35-75 years， with TG/HDL-C having the strongest association with diabetes and pre-diabetes， and is expected to be a key predictor for assessing the development of diabetes.

Objective:To compare the efficacy of double mini locking plate and anatomical locking plate in the treatment of comminuted olecranon fracture.Methods:The clinical data of 46 patients who underwent comminuted olecranon fracture in the Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from March 2017 to May 2020 were analyzed retrospectively. Among them, 21 cases were treated with double mini locking plate (double plate group) and 25 cases with anatomical locking plate (single plate group). The operation time, patient satisfaction, range of motion, return to work time, soft tissue stimulation to remove internal fixation, Mayo elbow performance score (MEPS), disabilities of arm, shoulder and hand score (DASH) of the two fixation methods were statistically compared. Measurement data with normal distribution were represented as ( ± s), and comparison between groups was conducted using the t test. Comparison between groups of count data was conducted using the chi-square test or Fisher exact probability. Results:All 46 patients were followed up for to (19.17±2.79) months. All fractures healed after operation. There was no significant difference in operation time, range of motion, patient satisfaction, MEPS and DASH scores among the two groups( P>0.05). The time of returning to work was (8.47±2.13) weeks in the double plate group and (9.78±1.98) weeks in the single plate group, and the difference was statistically significant ( P< 0.05). There were 9 cases of internal fixation due to soft tissue stimulation, 1 cases in double plate group and 8 cases in single plate group, and the difference was statistically significant ( P<0.05). Conclusions:Compared with anatomical locking plate, the treatment of olecranon fracture with double mini locking plate can effectively reduce soft tissue stimulation and promote patients to return to work early, and the operation time is not significantly prolonged, and the biomechanical advantage is obvious, the clinical effect is satisfactory and the postoperative function is good, so it is an effective treatment.

Objective:To analyze the clinical outcomes of tibial bone transport over an intramedullary nail in combination with antibiotic-loaded calcium sulphate for treatment of segmental bone defect.Methods:A retrospective analysis was conducted by enrolling 11 surgically treated patients with tibial segmental bone defect after the debridement for tibial infection or osteomyelitis who were admitted in Lower Limb Surgery Ward of Traumatic Orthopedic Department, Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from Jan. 2018 to Jan. 2020. The collected clinical materials and data included gender, age, injury mechanism, smoke or alcohol, comorbidities, intraoperative bleeding loss, bone defect length, resorption time of calcium sulphate, bone transport time, external fixation time, external fixation index, complications and Paley bone and functional criteria. SPSS 24.0 software was used to analyze the data.Results:Eleven patients were followed up for 8 to 31 months (average 23.2 months). All patients achieved bone healing and the infection was eradicated with no sign of recurrence. The mean length of defect was (8.1±1.6) cm, mean resorption time of calcium sulphate was (6.6±2.6) months, bone transport time was (11.4±2.8) weeks, external fixation time was (4.7±1.2) months, external fixation index was (0.58±0.07) month/cm and full weight bearing time was (6.1±1.4) months. The complication rate was 36.4% including deep vein thrombosis, delayed union of the docking site, pin tract infection and sterile draining of the wound. Paley bone evaluation results were excellent and good in 10 patients (90.9%) and functional results were excellent and good in 11 patients (100%).Conclusion:Tibial bone transport over an intramedullary nail in combination with antibiotic-loaded calcium sulphate is a safe, reliable and successful method for segmental bone defect and eradication of infection which reduces external fixation time and complication rate, allows patients perform weight bearing and return to daily life earlier.

Objective:To study the influence of anticoagulation timing on incidence of perioperative deep venous thrombosis (DVT) in elderly patients with hip fracture.Methods:A retrospective analysis was made of the 179 elderly patients with hip fracture who had been admitted to Department of Orthopedics and Traumaology, Hong-Hui Hospital from July 2017 to December 2018. They were 78 males and 101 females, aged from 62 to 91 years (mean, 79.5 years). There were 79 femoral neck fractures and 100 intertrochanteric fractures, 109 of which were treated by internal fixation and 70 by hip replacement. The patients were divided into 3 groups depending on the timing of anticoagulation after injury. In group 1 of 74 cases, anticoagulation started <24 h after injury; in group 2 of 36 cases, anticoagulation started 24 to 48 h after injury; in group 3 of 69 cases, anticoagulation started >48 h after injury. Anticoagulation continued until 12 h before surgery in all patients but was resumed 8 to 12 h after surgery. The 3 groups were compared in incidence of perioperative DVT.Results:The 3 groups were comparable due to insignificant differences between them in their pre-operative general data ( P>0.05). DVT occurred perioperatively in 84 patients, yielding an incidence of 46.9% (84/179). The incidences of perioperative DVT were 27.0% (20/74), 47.2% (17/36) and 68.1% (47/69) in groups 1, 2 and 3, respectively, showing significant differences ( χ2=24.206, P<0.001), between any 2 groups ( P<0.05). Conclusion:Since the earlier anticoagulation starts after injury the lower incidence of perioperative DVT in elderly patients with hip fracture, early standardized prophylactic anticoagulation after injury can effectively reduce incidence of perioperative DVT.

Objective To explore the sleep characteristics of submariners during a long-term voyage, so as to provide scientific evidence for ensuring submariners with good sleep during long-term voyages. Methods The sleep status of submariners who participated in a long-term voyage was tested by Self-Rating Scale of Sleep (SRSS) before the voyage, and before and after each voyage section during the voyage. The sleep status variation of submariners who performed different types of tasks, from the beginning to the end of each voyage section and of each resting-on-the-sea section was analyzed respectively. Comparison of sleep scores was performed between submariners and surface ship crew in the second voyage section. Numbers of submariners with sleep problem were compared in each voyage section. Results Generally speaking, submariners' sleep status at the end of voyage section was significantly worse than that at the beginning of voyage section and that before the whole voyage (P<0.001, P<0.01), and the sleep status at the beginning of the third voyage section was significantly worse than that before the whole voyage (P<0.05). Submariners had a steady sleep status when taking a resting-on-the-sea before starting their first voyage section, which was no significant difference from that before the whole voyage (P>0.05). After finishing a voyage section and taking a resting-on-the-sea, submariners' sleep status returned to the level of pre-voyage (P>0.05), and was significantly better than that before the resting-on-the-sea (P<0.05, P<0.01). After finishing two voyage sections and then taking a resting-on-the-sea, the submariners' sleep status showed no obvious variation (P>0.05). Compared with that of surface ship crew who accomplished the same voyage section, submariners had an obviously better sleep status after taking a resting-on-the-sea (P<0.05). Meanwhile, submariners who finished a voyage section showed a significantly worse sleep status than those resting on the sea (P<0.01) and surface ship crew who finished a same voyage section (P<0.05). In each voyage section, submariners with sleep problems who finished resting-on-the-sea were significantly less than those who finished navigation (P<0.001, P<0.05). There was no significant difference in the number of submariners with sleep problems between those who taking non-resting and taking resting-at-dock after finishing the first voyage section (P>0.05), but the latter was significantly more than the former when the second voyage section was finished (P<0.05). During the resting-on-the-sea period, the numbers of submariners with sleep problems in both the second and the third voyage section were significantly more than those in the first voyage section (P<0.05, P<0.01). The numbers of submariners with sleep problems who implemented the third voyage section were significantly more than those who implemented the first and the second voyage section (P<0.01). Conclusions Generally, the sleep quality of submariners is significantly worse after accomplished a voyage section task, and the degree of sleep problems may be accumulated to worse and worse along with the increase of long-term voyage time. Whereas, submariners may have a significantly better sleep status after taking a resting-on-the-sea, implying that resting-on-the-sea is an effective way to ensure submariners a good sleep during a long-term voyage.

Objective To investigate the effects of angiotensin Ⅱ on nuclear transcription factor-кB(NF-кB)and interleukin-8(A549 cells),and to explore the underlying mechanisms of ventilator-induced lung injure. MethodA549 cells were maintained in Dulbecco' s modified Eagle's culture medium at 37℃ with 5 ％ CO2 incubator. The cells were randomly (random number) divided into 4 groups (n =24 in each). The group A was control group. The group B,C and D had A549 cells co-incubated with Angiotensin Ⅱ 10-6 mmol/L (final concentration) for 1 h,2 h and 4 h, respectively. The samples of cell culture supematant,total cellular RNA and nuclear proteins were collected or extracted after culture of cells. The II-8 contents in cell culture supernatant were detected with enzyme linked immunosorbent assay(FLISA) .The expressions of IL-8 mRNA were measured by reverse ttanscription-polymerase chain reaction (RT-PCR).The NF-κB activities were assayed with electrophoretic mobility shift assay (EMSA). The levels of NF-κB p65 subunit were detected with Western blot. The overall differences were compared by using analysis of variance(ANOVA). Differences between two groups were assessed by q tests. ResultsThe levels of IL-8 content in cell culture supematant in groups A, B, C and D were (29.59+8.36) pg/mL,(135.35 + 28.93) pg/mL,(357.12+ 57.21) pg/mL,and (1732.13+ 261.73) pg/mL,respectively(group A vs. group B, P ＜0.01; group B vs group C, P ＜0.01;group C vs. group D, P ＜ 0.01 ) The overall differences between gtoups were statistically significant ( F =58.41,P ＜ 0.05). The expressions of IL-8 mRNA in groups A, B, C and D were (0.13±0.03)Au·nm,(0.49+0.08) Au·mm,(0.71 ±0.10) Au·mm and (0.88±0.11) Au·mm,respectively (group A vs. group B, P ＜0.01; group B vs. group C, P ＜ 0.01; group C vs. group D, P ＜ 0.05. The overall differences between groups were statistically significant (F = 19.08, P ＜ 0.05). The NF-κB activities in groups A, B, C and D were (70.37±6.57) Au·mm,(139.76± 11.72) Au·mm,(198.90± 18.95)Au·mm and (388.73±26.27) Au·mm, respectively (group A vs. group B, P ＜0.01,group B vs. groupC, P ＜0.05; group C vs. group D, P ＜ 0.01 ). The overall differences between groups were statistically significant ( F = 23.15, P ＜ 0.05). The levels of NF-κB p65 subunit in groups A, B＜ C and D were (33.05±6.23) Au·mm, (73.97 ± 5.34) Au·mm,(168.72± 8.40)Au·mm and (254.63 + 12.2) Au·mm, respectively (group A vs. group B, P ＜0.01; group B vs. group C, P ＜0.01; group C vs. group D, P ＜0.01). The overall differences between groups were statistically significant (F = 16.33,P ＜ 0.05). Conclusions The Ang Ⅱ can significantly activate the NF-κB system and up-regulate the expression of IL-8 in human lung adenocarcinoma cell line, which cause neutrophil infiltration and activation. This effect is time-dependent and induces acute lung injure, playing an important role in the underlying mechanisms of ventilator-induced lung injure.
