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:Pediatric chronic sinusitis （CRS） is a common disease within the field of otolaryngology-head and neck surgery. Due to the immaturity of sinus development and immune competence in children, its etiology and pathophysiology are complex, and its clinical features and outcomes differ significantly from those in adult patients. Currently, there are issues in the diagnosis and treatment of pediatric CRS, particularly in areas such as antibiotic use and surgical interventions, owing to a lack of sufficient attention. In recognition of this, the Chinese Rhinopathy Research Cooperation Group developed this expert consensus based on a systematic review of the latest literatures from both domestic and international sources, with reference to the latest evidence-based medical evidence worldwide, and in combination with their own clinical experience. The consensus covers various aspects including epidemiology, predisposing factors, pathophysiology, diagnosis and differential diagnosis, as well as treatment strategies such as medical therapy and surgical intervention. It aims to standardize the clinical diagnosis and treatment of pediatric CRS, improve clinical efficacy and patient satisfaction, reduce clinical expenditures, and decrease the occurrence of adverse reactions.

Objective:To explore the value of linaclotide combined with compound polyethylene glycol electrolytes powder (PEG) for bowel preparation for colonoscopy.Methods:A randomized and single blind prospective clinical study was conducted in patients who intended to receive colonoscopy at the Department of Gastroenterology in Shenzhen Hospital, Southern Medical University from June 2021 to August 2021. One hundred and fifty-two patients in the experimental group were treated with 580 μg linaclotide + 2 L PEG, and 152 patients in the control group were treated with 3 L PEG. The bowel preparation effects including Boston bowel preparation scale (BBPS) score, bubble score and lesion detection rate, and safety (adverse events) were compared between the two groups.Results:The total BBPS scores were 9 (8, 9) in the experimental group, and 9 (9, 9) in the control group with no significant difference ( Z=0.141, P=0.888). The bubble scores were 1 (1, 2) in the experimental group, and 1 (1, 1) in the control group with no significant difference ( Z=1.788, P=0.074). There was no significant difference in detection rate of lesions between the experimental group and the control group [37.50% (57/152) VS 33.55% (51/152), χ2=0.517, P=0.472]. There was no significant difference in safety including incidence of nausea [7.24% (11/152) VS 13.16% (20/152), χ2=2.910, P=0.088], vomiting [2.63% (4/152) VS 7.24% (11/152), χ2=3.436, P=0.064], abdominal distension [7.89% (12/152) VS 11.84% (18/152), χ2=1.331, P=0.249] and abdominal pain [2.63% (4/152) VS 4.61% (7/152), χ2=0.849, P=0.357] between the experimental group and the control group. Conclusion:Linaclotide combined with PEG for colonoscopic bowel preparation reduces drinking water volume. The cleaning effect and safety are comparable to using 3 L PEG. It can be recommended for bowel preparation for colonoscopy.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

Objective To investigate the expressions of inflammation- and fibrosis-related genes in perinephric and subcutaneous adipose tissues in patients with adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome. Methods The perinephric and subcutaneous adipose tissues adipose tissues were obtained from 8 patients with ACTH-independent Cushing's syndrome undergoing laparoscopic retroperitoneal adrenalectomy. Real-time PCR was used to detect the mRNA expression levels of interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), matrix metallopeptidase 2 (MMP-2), TIMP metallopeptidase inhibitor 1 (TIMP-1), early growth response 1 (EGR1), CCAAT/enhancer binding protein β(CEBPβ), uncoupling protein 1(UCP-1), PPARγ coactivator 1 alpha (PGC1α) and cell death-inducing DFFA-like effector a (CIDEA). Results The mRNA level of CIDEA was significantly higher in the perinephric adipose tissue (peri-N) than in the subcutaneous adipose tissue (subQ) (P<0.05). The expressions of CEBPβ, UCP-1, and PGC1αmRNA in the peri-N were similar with those in the subQ. The expressions of IL-6, TIMP1 and EGR1 mRNA in the subQ were significantly higher than those in the peri-N (P<0.05). No significant difference in TNF-α and MMP-2 mRNA levels was found between peri-N and subQ. Conclusion The expression levels of the inflammation-and fibrosis-related genes are higher in the subQ than in the peri-N of patients with ACTH-independent Cushing's syndrome, suggesting that chronic exposure to endogenous hypercortisolism may cause adipose tissue dysfunction.

Objective To assess the reproducibility of long-term blood pressure variability in ischemic stroke and the association between the variability and cerebral microbleeds.Methods Patients with ischemic stroke at the previous 1-6 months were consecutively recruited and followed up 12-18 months.Blood pressure measurements were taken at every interview.Blood pressure variability indicated visit-to visit variability and was quantified by calculating the maximum ( Max),standard deviation (SD) and coefficient of variation (CV).For these variability might positively correlated with mean of blood pressure,the additional variability measure,SD independent of mean (SDIM),was also calculated.To determine the reproducibility of mean and variability measurements,the intraclass correlation (ICC) was also calculated.MRI was performed at baseline and the end of the study.Cerebral microbleeds were rated using Microbleed Anatomical Rating Scale (MARS).Multiple Logistic regression was used to assess the association between the visit-to-visit blood pressure variability and cerebral microbleeds.Results A total of 720 patients were recruited,of whom 595 (82.6％) subjects were present for 14 blood pressure readings during follow-up.The visit-to-visit blood variability measurements were moderately reproducible according to the ICC:0.46-0.72 for systolic blood pressure (SBP) and 0.42-0.69 for diastolic blood pressure ( DBP),respectively,P ＜0.01 for all measures.Patients with cerebral microbleeds were more likely to have higher mean blood pressure and variability for both SBP and DBP regardless the distribution of cerebral microbleeds.Being SBP Max,SBP SD,SBP CV,SBP SDIM(OR=1.036,95％ CI l.021-1.052,P=0.000; OR=1.060,95％CI 1.001-1.122,P =0.046; OR =1.084,95％ CI 1.000-1.175,P =0.049; OR =1.065,95％ CI 1.002-1.132,P =0.044) and DBP SD,DBP CV ( OR =1.111,95％ CI 1.000-1.233,P =0.049;OR =1.091,95％ CI 1.001-1.190,P =0.047) were the independently risk factors of cercbral microbleeds at deep region; SBP Max( OR =1.049,95％ CI 1.029-1.068,P =0.000) and DBP SD、DBP CV(OR =1.236,95％ CI 1.107-1.379,P=0.000;OR =1.188,95％ CI 1.087-1.298,P=0.000)independently associated with cerebral microbleeds at infratentorial location.There was no significant relation between the long-term variability of blood pressure and cerebral microbleeds at lobar region. Conclusions This study indicates that long-term blood pressure variability is substantial and independently associated with cerebral microbleeds in deep or infratentorial but not with that in lobar region.The different relations between the variability and cerebral microbleeds might indicate the heterogenic mechanisms of cerebral microbleeds.

Objective To investigate the clinical presentation,laboratory features,imaging findings and CYP27A1 gene mutations of cerebrotendinous xanthomatosis (CTX) for improving the recognition and the early diagnosis and treatment of the disease.Methods Medical records and 8 months follow-up data of one patient who had been clinical diagnosed as CTX were collected and the pedigree and gene mutation analysis of the patient were carried out.Meanwhile,the clinical characters of CTX were analyzed according to the data from our patient and the review of the literature. Results Patient was a 36 years old male manifested with mental retardation, bilateral corticospinal tract and corticonuclear tract impairment,cerebellar lesions and peripheral neuropathy; head MRI indicated symmetric abnormal signals of bilateral basal ganglia,cerebellar dentate nucleus softening and calcification lesions; Achilles tendon MRI indicated markedly thickened Achilles tendon; gene mutation analysis showed sterol-27-hydroxylase gene( CPY27A1 )C→T homozygous mutation in 1016 nucleotide of exon 5.Ursodesoxycholic acid was given as treatment.In 8 months of follow up,for the first 6 months,the patient took medicine regularly and the illness condition was stable.But for the nearly 2 months,the patient voluntarily stopped medicine and the illness condition was worse.Conclusions CPY27A1 gene C→T homozygous mutation in 1016 nucleotide of exon 5 leads to CTX in the patient, which conforms to the characteristic of autosomal recessive disorder. CTX has some characteristic clinical manifestations,such as Achilles tendon thickening,intelligent declining and so on.But lack of specificity of early radiographic examination makes CTX easy to be delayed diagnosis and treatment.CYP27A1 gene mutation analysis has an important significance for early diagnosis of CTX,which should be paid more attention,while the early application of chenodeoxycholicacid treatment can delay the progression of the disease.
