Objective:To analyze the clinical characteristics, treatment, and prognosis of ectopic bronchogenic cysts in children.Methods:A retrospective analysis was conducted on the data including the clinical characteristics, auxiliary examination and treatment of 21 children with ectopic bronchogenic cysts diagnosed pathologically at Children′s Hospital Affiliated to Zhengzhou University from July 2015 to December 2023. There were 16 males and 5 females, with a male-female ratio of 3.2∶1, and the age ranged from 4 days to 8 years old (median age 2 years and 8 months).Results:Among the 21 cases of ectopic bronchogenic cysts, 11 cases were found in the pharynx, with symptoms including dyspnea (4 cases), snoring during sleep (3 cases), and choking on milk(4 cases).Ten cases were found in the head, neck or anterior chest, 5 of these cases had infection history, and 5 showed progressive mass growth.Imaging and endoscopy showed 9 patients underwent preoperative color ultrasonography revealed cystic masses with well-defined boundaries. CT examination was performed on 13 patients, which showed round or nearly round masses with homogeneous density, smooth margins, and regular cyst walls. CT attenuation values ranged from 2 to 52 Hounsfield Units (HU). Four cystic lesions were assessed via MRI, 3 cases demonstrated long T1 and long T2 signals, while 1 case had a slight short T1 and long T2 signal, with high signal intensity on fat-suppressed images. Eleven cases of pharyngopharyngeal cysts were examined by electronic nasopharyngoscopy. The cysts appeared as spherical or ovoid masses with smooth surfaces, close to or slightly light in color with the surrounding tissue, with one cyst presenting with a bluish blue in the oropharynx. All 11 pharyngeal cysts were excised using low-temperature plasma under general anesthesia and intubation assisted by a nasal endoscope. The cysts were pulled and excised as completely as possible.Ten cases of neck and anterior chest cysts were completely excised. Postoperative histopathology confirmed bronchogenic cyst. Twenty-one children were followed up postoperatively for 4 months to 7 years without recurrence, except for 1 patient who was lost to follow-up.Conclusions:Ectopic bronchogenic cysts are uncommon and lack of typical imaging and clinical features.Combination of ultrasonography, CT and MRI is recommended for cases occuered in neck and anterior chest, while electronic nasopharyngoscopy complements pharyngeal evaluations. Surgical intervention is the preferred treatment choice for this disease.

Prevalence of childhood obesity is progressively increasing, reaching worldwide levels of 5.6% in girls and of 7.8% in boys. This also leads to a corresponding increase in the prevalence of obesity-associated morbidities particularly those involving obstructive sleep apnea（OSA）. Obesity is an independent risk factor and regulator of OSA in children. There is a bidirectional causal relationship between OSA and obesity in children. The factors involved in the association between OSA and obesity are systemic inflammation, oxidative stress, and gut microbiota etc. However, a causal link between obesity-related inflammatory state and OSA pathogenesis still needs to be properly confirmed. The present review aimed to investigate the links between childhood obesity and OSA.

BACKGROUND: Bronchial tuberculosis is a common complication of pulmonary tuberculosis. The present report is to investigate and analyze the indication and efficacy of surgical treatment of bronchial stricture due to severe endobronchial tuberculosis, when the drug and endoscopic treatment were no effect. METHODS: Reviewed the clinical-pathological records documenting the surgical outcomes in 36 bronchial stricture due to severe endobronchial tuberculosis who underwent lobectomy or pneumonectomy enrolled in our hospital between January 2000 and February 2016. Pneumonectomy in 8 cases, lobectomy in 23 cases, sleeve resection in 5 cases. RESULTS: No intraoperative or early postoperative death occurred. Six patients developed complications. All 6 cases recovered well after treatment. CONCLUSIONS Surgical treatment is still the recommended treatment modatity for bronchial stricture caused by endobronchial tuberculosis due to its good results. It should be performed in time when the drug and intraluninal treatment were no effect for avoiding of being progeressed.

Objective To investigate the correlation between auditory steady-state response (ASSR)and behavioral audiometry threshold in deaf children.Methods A total of 63 cases (126 ears)of severely and profoundly hearing impaired children from 0.5 years to 6 years were divided to Group A of 0.5~1.0 years,Group B of 1.1~3.0 years and Group C of 3.1~6.0 years old.ASSR and behavioral hearing tests were conducted in the sound field. 0.5~1.0 years old children were tested with the behavior observation Audiometry (BOA),1~2 years old children with visual reinforcement audiometry (VRA),while those of 3 ~6 with play audiometry (PA).Results For the ASSR response thresholds and pure tone hearing thresholds at 0.5,1,2 and 4 kHz,the correlation coefficients were 0.75,0.76,0.76,and 0.83,respectively.There was a significant correlation (P <0.01 ).The hearing thresholds were generally lower than the ASSR response thresholds,and with increasing frequency,the gaps were narrowed between the two.For Group A at each frequency the response thresholds and behavioral audiometry correlations were lower than those of Group B and C with the lowest at 0.5 kHz.Conclusion For the children of 0.5~6 years, ASSR and behavioral audiometric thresholds have good correlations.ASSR can provide information about the behav-ior thresholds for young children and those high risk children and for fitting hearing aids.

OBJECTIVE: To preliminarily determine the gene mutation frequency and the hotspots in Henan province, we analysed the deafness-related gene mutation in patients with non-syndromic hearing loss (NSHL). METHOD: Genomic DNA samples of 100 patients with NSHL in Henan province were extracted from peripheral blood after clinical history inquiry and clinical examination, Four common deafness genes GJB2, SLC26A4, mitochondrial 12SrRNA, and GJB3 were detected by Sanger sequencing method,and then data analysis were conducted. RESULT: Among 100 patients with NSHL. the gene mutation frequency was 44%. In these patients, 29 cases had GJB2 mutations, 13 cases had SLC26A4 gene mutations, and 3 cases had mitochondrial 12SrRNA mutations. CONCLUSION Among the patients with NSHL in Henan province, the most frequent mutation causing hereditary deafness was mutation in GJB2, followed by SLC26A4,and it will provide a theoretical basis to determine the etiology of deafness in Henan Province.

Objective This study aims to analyze the independent risk factors of acute respiratory dysfunction (ARD) in children with airway foreign body and to assess possible prevention and treatment option in the future.Methods Clinical data of 456 cases of children with airway foreign body were retrospectively collected and analyzed by cluster sampling,including 246 males and 210 females,who received operation in our hospital between July,2009 and December,2012,aged 0.5-11 years old,onset to treatment time was 0.15-14 days.Chnical characteristics including age,gender,past medical history,time of onset,temperature,location of the foreign body,category of foreign bodies,complicated by pneumonia,complicated by subcutaneous and mediastinal emphysema were gathered.Temperature,respiratory rate,heart rate,cyanosis,transcutaneous oxygen saturation or arterial blood analysis were assayed before operation.Risk factors with statistical significance were screened with univariate logistic regression analysis,independent risk factors of ARD were determined with multivariate logistic regression analysis.Results Acute respiratory dysfunction occurred in 78 (17.1％) patients.The foreign bodies in 455cases were successfully removed brocboscopically in the first time.One case received chest surgery for foreign body removal.Total of 452 cases were successfully extubated and ventilator weaned 4-6 h after brochoscopy.In 2 cases,the ventilator was weaned 2-4 d after brochoscopy in ARD gup,and 2 cases with severe pneumonia died.Age,location of the foreign body,temperature,complicated by pneumonia,complicated by subcutaneous and mediastinal emphysema did not show significant difference between acute respiratory dysfunction group and non-acute respiratory dysfunction group (P ＜ 0.05).Multivariate logistic regression analysis showed location of the foreign body and complicated by pneumonia,complicated by subcutaneous and mediastinal emphysema were independent risk factors for ARD.Conclusion Early judgement of the risk factors of acute respiratory dysfunction in children with airway foreign body can provide a reference for the operation and perioperation period treatment.

BACKGROUNDWith the development of social industrialization and aging of the population, patients with lung cancer have the tendency of becoming youthful and elderly, therefore the way of treatment should be also changed. In resent years, lung cancer in young and elderly patients have been reported respectively, but simultaneous contrast analysis of clinical feature and prognosis in elderly, normal and youthful patients have been rarely reported. Based on the clinic data in the patients, the clinical feature and prognosis of patients with non-small cell lung cancer at different ages were analyzed.

METHODSFrom January 1996 to January 2003, 1380 patients with NSCLC were treated surgically in thoracic department in our hospital, the patients were divided into three group based on their age, group 1 (G1) (range ≤40), group 2 (G2) (range 41-69), group 3 (G3) (range ≥70). The clinical feature and prognosis were analyzed in each group.

RESULTSThe mean age in the whole group was 58.16±0.26, and 35.76±0.57 (range 12-40) in G1, 58.00±0.22 (range 41-69) in G2, 72.30±0.21 (range 70-80) in G3. The ratio of lung cancer in female between G1 and G3 was significant different (P=0.024). The coexisting diseases in G3 were more common than those of other groups (P=0.000). Squamous cell carcinoma was the main type in histology, accounting for 41.79% (28/67), 54.12% (644/1190) and 58.54% (72/123) in each group respectively (P=0.080), but the ratio of adenocarcinoma, higher than that of other groups, were 43.28% (29/67), 29.50% (351/1190) and 26.82% (33/123) (P=0.036). Lobectomy and pneumonectomy were the main surgical procedures, accounting for 58.21%, 65.29%, 78.86% (P=0.004) and 34.33%, 26.22%, 12.20% (P=0.001), respectively. The ratio of stage III were 43.28% (29/67), 38.82% (462/1190), and 26.02% (32/123) in each groups (P=0.015). 55.22% (37/67) in G1 received adjuvant chemotherapy, 47.48% (565/1190) in G2, and 29.27% (36/123) in G3 (P=0.000). 5-year survival rate was 38.96% in the whole group, 29.99% in G1, 39.61% in G2, and 37.99% in G3 (P=0.494).

CONCLUSIONSIn young patients with non-small cell lung cancer, female and adenocarcinoma make up the majority of the number, and a lot of patients are in advanced stage and likely to adopt adjuvant chemotherapy. While in elderly, squamous cell carcinoma accounts for the majority of the number, and more coexisting diseases are accompanied, much more complications occur after surgical procedure. Nevertheless, their prognosis has no significant difference.
