To examine the evolution of surgical techniques and trends in overall inpatient burden for pediatric adenoidectomy in Beijing tertiary hospitals from 2013 to 2022. A retrospective observational study was conducted using the regional health information platform of Beijing. Data from children aged ≤14 years who underwent adenoidectomy between 2013 and 2022 were extracted, including total hospitalization cost, length of stay(LOS), surgical material cost, surgical fee, operative technique, perioperative antimicrobial drugs cost, coagulation factor cost, and blood transfusion cost. The Mann-Kendall trend test was used to assess temporal changes in total hospitalization expenses and the structure of cost components. The results showed that over the 10-year period from 2013 to 2022, a total of 25 989 children underwent adenoidectomy in tertiary hospitals. The proportion of children aged ≤6 years increased from 59.83% to 76.11%, showing a significant upward trend ( Z=2.15, P=0.032). Only one case required surgical hemostasis due to postoperative bleeding. During the ten-year period, the median hospitalization cost for adenoidectomy in tertiary hospitals was ￥12 425.82 (￥11 307.43, ￥14 955.42).Overall hospitalization cost demonstrated a fluctuating downward pattern, decreasing from ￥15 229.73 in 2013 to ￥13 927.52 in 2022, this declining trend was not statistically significant( Z=-0.54, P=0.592). In contrast, the surgical costs showed an upward trend over the decade increasing from ￥1 856.22 in 2013 to ￥3 726.45 in 2022, which was statistically significant ( Z=3.22, P=0.001), while the cost of surgical materials showed no significant increase ( Z=1.79, P=0.074).Concurrently, the average LOS decreased remarkably from 10.56 days in 2013 to 3.26 days in 2022 ( Z=-3.94, P<0.001). The cost of perioperative antimicrobial drugs decreased ( Z=-3.94, P<0.001), while the cost of coagulation factors and blood transfusion remained unchanged ( Z=0.54, P=0.592; Z=0.56, P=0.578). Comparison between 2013-2017 and 2018-2022 showed a significant increase in the use of coblation from 28.9% to 42.5% ( χ2=638.7, P<0.001).Furthermore, in the coblation group, total hospitalization cost decreased by 27.73%, surgical cost increased by 94.98%, surgical material cost decreased by 10.33%, LOS shortened by 56.24%, and antimicrobial drug cost increased by 43.03%. In contrast, the non-coblation group showed a 23.94% increase in total hospitalization cost, a 57.08% increase in surgical procedure cost, a 33.88% increase in material cost, and a 30.14% reduction in LOS and a 26.0% decrease in antimicrobial drugs cost. In conclusion,from 2013 to 2022, total hospitalization cost for pediatric adenoidectomy in Beijing tertiary hospitals remained stable. Compared to non-coblation techniques, coblation was associated with a shorter LOS, lower total costs, a higher proportion of surgical fees, and a decreased proportion of material costs, without a significant increase in overall healthcare costs.

Objectives:To explore the clinical characteristics of children with adenoid hypertrophy (AH) and laryngopharyngeal reflux (LPR) by detecting the expression of pepsin in adenoids as a standard for AH with LPR.Methods:A total of 190 children who were admitted for surgical treatment due to AH were included in the study. The main clinical symptoms of the patients were recorded, and the degree of adenoid hypertrophy was evaluated. Before the surgery, Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) were used to evaluate the reflux symptoms. After the surgery, pepsin immunohistochemical staining was performed on the adenoid tissue, and according to the staining results, the patients were divided into study group (pepsin staining positive) and control group (pepsin staining negative). SPSS 19.0 software was used for statistical analysis. Quantitative data conforming to normal distribution between the two groups were tested by two-independent sample t test, and quantitative data with skewed distribution were tested by Mann-Whitney U test. Results:The positive rate of pepsin staining in the 190 AH patients was 78.4% (149/190). The study group had higher levels of preoperative symptoms such as erythema and/or congestion of the pharynx(2.1±0.7 vs. 1.8±0.6, t=2.23), vocal cord edema[1.0(0, 1.0) vs. 1.0(0, 1.0), Z=2.00], diffuse laryngeal edema[0(0, 1.0) vs. 0(0, 0), Z=2.48], posterior commissure hypertrophy[(1.4±0.6 vs. 1.1±0.5), t=2.63], and a higher total score on the RFS scale than the control group(6.2±2.7 vs. 5.0±2.6, t=2.47), with statistical differences ( P<0.05). The sensitivity and specificity of RFS score in diagnosing AH with LPR were 24.8% and 80.5%, respectively. When RFS>5 was used as the positive threshold, the sensitivity and specificity of RFS score in diagnosing AH with LPR were 61.1% and 58.5%, respectively. There was a statistical difference in the number of positive cases of RFS score between the study group and the control group(91 vs. 17, χ2=5.04, P=0.032). Conclusions:LPR is common in AH children. Children with AH and LPR have specific performance in electronic laryngoscopy, such as erythema with edema in the pharynx, posterior commissure hypertrophy, and vocal cord edema.

Objective:To investigate the correlation between serum Neuropilin 1 (NRP1) level and postoperative recurrence in patients with adenomyosis.Methods:From Mar. 2019 to Mar. 2021, 80 patients with adenomyosis admitted to our hospital were regarded as the test group; 80 healthy women who came to our hospital for physical examination were as the reference group. Patients with adenomyosis were followed up for 24 months after surgery and were separated into a non recurrence group (62 cases) and recurrence group (18 cases) based on whether there was recurrence after surgery. Enzyme-linked immunosorbent assay (ELISA) was applied to detect NRP1 level in the serum of the study subjects. Spearman method was applied to analyze the correlation between serum NRP1 level and visual analogue dysmenorrhea score (VAS) and menstrual blood loss (PBAC) scores in patients with adenomyosis. Multivariate Logistic regression was applied to analyze the influencing factors of postoperative recurrence in patients with adenomyosis. Receiver operating characteristic (ROC) curve was applied to analyze the predictive value of serum NRP1 level for postoperative recurrence in patients with adenomyosis.Results:Compared with the reference group, the serum NRP1 level of patients with adenomyosis in the test group was obviously increased ( P<0.05). Compared with the non recurrence group, the recurrence group showed a obvious increase in serum NRP1 level, uterine volume, dysmenorrhea VAS score, and PBAC score ( P<0.05). Spearman’s method showed a positive correlation between serum NRP1 level and dysmenorrhea VAS score in patients with adenomyosis ( r=0.604, P<0.001) ; the serum NRP1 level in patients with adenomyosis was positively correlated with PBAC score ( r=0.586, P<0.001) ; the serum NRP1 level in patients with adenomyosis was positively correlated with uterine volume ( r=0.527, P<0.001). The results of multivariate logistic regression analysis showed that serum NRP1 level, uterine volume, dysmenorrhea VAS score, and PBAC score were risk factors for postoperative recurrence in patients with adenomyosis ( P<0.05). The ROC curve showed that the AUC of serum NRP1 level in predicting postoperative recurrence in patients with adenomyosis was 0.903, which had certain clinical value. Conclusion:The serum NRP1 level in patients with adenomyosis obviously increases, which is closely related to postoperative recurrence in patients with adenomyosis.

The dysregulation of transcription factors is widely associated with tumorigenesis. As the most well-defined transcription factor in multiple types of cancer, c-Myc can transform cells by transactivating various downstream genes. Given that there is no effective way to directly inhibit c-Myc, c-Myc targeting strategies hold great potential for cancer therapy. In this study, we found that WSB1, which has a highly positive correlation with c-Myc in 10 cancer cell lines and clinical samples, is a direct target gene of c-Myc, and can positively regulate c-Myc expression, which forms a feedforward circuit promoting cancer development. RNA sequencing results from Bel-7402 cells confirmed that WSB1 promoted c-Myc expression through the β-catenin pathway. Mechanistically, WSB1 affected β-catenin destruction complex-PPP2CA assembly and E3 ubiquitin ligase adaptor β-TRCP recruitment, which inhibited the ubiquitination of β-catenin and transactivated c-Myc. Of interest, the effect of WSB1 on c-Myc was independent of its E3 ligase activity. Moreover, overexpressing WSB1 in the Bel-7402 xenograft model could further strengthen the tumor-driven effect of c-Myc overexpression. Thus, our findings revealed a novel mechanism involved in tumorigenesis in which the WSB1/c-Myc feedforward circuit played an essential role, highlighting a potential c-Myc intervention strategy in cancer treatment.

Objective: To understand the effect of treating obstructive sleep apnea hypopnea syndrome (OSAHS) on chronic cough in children. Methods: A total of 100 consecutive children with OSAHS diagnosed by polysomnography(PSG) and chronic cough were included in this study. All children underwent cough condition assessment, OSA-18 scales and MS-IOS before and after surgery, and all children were followed-up for 3 months. Children were separated into three groups according to the severity of OSAHS. Related parameters like Zr, Rf, R5, R20, X5, X35, Rc, Rp obtained from MS-IOS, OSA-18 scores and cough scores were compared between different groups using paired t-test or Wilcoxon sum test. Results: There existed significantly positive correlations between AHI and scores of OSA-18(r=0.653, P<0.01). AHI positively related to cough scores including diurnal(r=0.470, P<0.01)and nocturnal cough scores(r=0.459, P<0.01). Scores of OSA-18 had similarity in correlations with diurnal(r=0.527, P<0.01)and nocturnal cough scores(r=0.532, P<0.01). All children got improved in OSA-18 scales and cough scores after treatment. In details, the three groups were mild group(n=34), moderate group(n=37), severe group(n=29). OSA-18 scales decreased dramatically in each group after surgery, Z values were -5.014, -5.035, -4.624 respectively(P=0.000). Cough scores in day and night got reduced after treatment, Z values were -5.112, -5.102, -5.394, -5.374, -4.777, -4.770 in three groups. Rp in all children got alleviated after surgical management, Z were -3.150, -5.035, -5.374(P=0.000). Other parameters were analyzed using paired t test. Z5, R5, R20, R35 got reduced in all three groups.X5 got reduced in mild and moderate groups. Rc reduced only in the moderate group. Conclusions OSAHS may be a trigger or inducer of chronic cough. Active treatment of OSAHS via surgery can improve the quality of children′s life and alleviate the symptoms of cough in day and night.

Objective: To explore the characteristics of acute otitis media(AOM) in children in Beijing and its correlation with meteorological factors. Methods: Data were collected in 2011-2013 in the Otolaryngology Department of Capital Institute of Pediatrics. AOM in children with relevant information, such as age, sex and season, with the same period of the Beijing municipal meteorological data (the average temperature, average pressure, average wind speed, humidity and PM2.5) were compared to analysis the relationship of meteorological environmental parameters and the onset of AOM in children. Results: Annual morbidity of AOM was 7 589, 8 245, 7 242 respectively, no obvious difference(P=0.761). It was noted that one peak could be seen in December, and a valley in February, followed by August. Summer was less than the other three seasons (P<0.05). The morbidity of AOM had a small peak within one year after birth, then reached peak at the age of about 4, and then reduced gradually. In different age groups, male patients were higher than those of female. The incidence of AOM was positively correlation tendency with air pressure and PM2.5 (r=0.333, 0.093, P=0.000, 0.002), which was negatively correlation tendency with daily temperature or humidity (r=-0.327, -0.195, P=0.000, 0.000). Conclusions The incidence of AOM of children in Beijing changes with age, and has obvious seasonal variation. There may be some correlation between the meteorological factors and the incidence of AOM in children.
