OBJECTIVE: To investigate the relationship between obstructive sleep apnea hypopnea syndrome (OSAHS) and adenoid size as well as tonsil size in Children. METHOD: A total of 545 patients, 338 OSAHS patients (treated group) diagnosed by PSG and 207 patients with vocal cord nodules but symptoms of upper airway obstruction (control group), were enrolled from inpatient and outpatient between June, 2008 and October, 2010. The oropharynx and electron-nasopharyngolaryngoscopy examination records of the two groups were retrospectively analyzed. The patients in the treated group were also divided into mild group, moderate group and severe group according to obstructive apnea index (OAI) or AHI. SPSS 17.0 was used for statistical analysis. RESULT: In the treated group, 89.7% had grade III-V adenoid and 68.4% had grade III-IV tonsil, compared with 30.9% (adenoid) and 13.5% (tonsil) in the control group. The significant differences were found (all P < 0.01). The comparison between patients with different grades of adenoidal size and tonsil size in the treated group had indicated that patients with grade IV adenoid or grade IV tonsil have a higher risk of OSAHS than patients with grade III adenoid or grade III tonsil. In the treated group, the ratio of patients with different severity of adenoid or tonsil had increased with the severity of OSAHS (P < 0.01). This retrospective study had also found that most of the grading results from Electron-nasopharyngolaryngoscopy examination were consistent with that from oropharynx examination. 13 (37.1%) of 35 patients with grade I or II tonsil diagnosed by Oropharynx examination were considered as grade III by Electron-nasopharyngolaryngoscopy examination. CONCLUSION Adenoidal hypertrophy and tonsil hypertrophy are the risk factors for OSAHS in children. The risk of OSAHS and the severity of OSAHS are positively associated with the severity of adenoid and tonsil. The electron-nasopharyngolaryngoscopy examination is an important examination method for diagnosing OSAHS in children, as well as determination of tonsil size.

Objective To evaluate the effects of drug-eluting stents (DES) versus bare-metal stents (BMS) on clinical outcomes in patients with acute ST-segment elevation myocardial infarction (ASTEMI) receiving primary percutaneous coronary intervention (PPCI). Methods The 217patients with ASTEMI receiving PPCI from Jan. 2005 to Dec. 2007 were enrolled in this study. And they were divided into two groups: DES group (n=92) and BMS group (n=125). The baseline characteristics including age, gender, angiographic characteristics, stents characteristics, Killip classification, cardiac troponin I(CTnI)levels, left ventricular ejection fraction(LVEF), hemoglobin levels, hypertension, diabetes, hyperlipidemia, obesity and smoking of the two groups were collected.Clinical follow-up end point were major adverse cardiac event(MACE)including death, acute myocardial infarction, stent thrombosis and stent restenosis. Clinical follow-up duration was(16.8±11.3) months (6-38 months). Results The average age (years), rate of Killip classification (class 2, 3, 4), average diameter (mm) of stent were significantly higher in BMS group than in DES group(64.6±11.9 vs. 61.2±11.8, t=2.09, P=0.037;25.9% vs. 12.2%, χ2=5.53, P=0.019;3.07±0.38 vs. 2.91±0. 40, t=2.78, P=0.006). And the average LVEF (%) was significantly lower in BMS group than in DES group (55.4±11.9 vs. 60.3±12.8, t= -2.57, P=0.011). The average length (mm) of stent, rate of stent post dilatation and diabetes were significantly higher in DES group than inBMSgroup (32.8±16.2 vs. 26.2±11.2, t=-3.54, P=0.001;45.7% vs. 21.6%, χ2=13.85, P=0. 000;28.2% vs. 16.0%, χ2=4.77, P=0.030). MACE occurred in 36 patients during clinical follow-up, 6 in DES group and 30 in BMS group. Incidence of MACE was significantly lower in DES group than in BMS group(6.5% vs. 24.0%, χ2=11.70, P＜0.01). Conclusions Using DES in ASTEMI patients is safe and may improve clinical outcomes by reducing incidence of MACE compared with BMS.

Objective To explore the common causes of epilepsy and the etiologic characteristics in different age groups of patients with epilepsy.Methods A retrospective survey was made in 5572 epilepsy patients in Epileptic Center of Guangdong 999 Brain Hospital from January 2003 to December 2009.According to the diagnostic criteria published in 2005 from ILAE,all the diagnoses of 5572 cases were made by epileptic specialists.Based on history,cranial MRI or CT and pathologic data,causes of epilepsy were classified into idiopathic,symptomatic and cryptogenic epilepsy.The cases of symptomatic epilepsy were further arranged into different categories in different age grades,such as head trauma,perinatal injuries,infection in central nervous system, cerebral vascular disease, brain tumor, disorders of cortical development,neurocutaneous syndrome and others.The cases with febrile seizures and family history were collected,and positive ratio of febrile seizures and family history were contrasted in different categories of cases by Kruskal-Wallis test ( nonparametric test ).Results In 5572 cases,66 were idiopathic,2834 symptomatic,2672 cryptogenic,and the ratio of these causes was 1％,51％,48％ respectively.Among 2834 cases of symptomatic epilepsy,822 were head trauma,497 were perinatal injuries,360 were infection in central nervous system,249 were brain tumor,150 were cerebral vascular disease,135 were disorders of cortical development,62 were neurocutaneous syndrome and 559 were others. In brief,head trauma,perinatal injuries,infection in central nervous system,brain tumor and cerebral vascular disease were top 5 causes of symptomatic epilepsy. Hippocampal sclerosis was found in 744 cases in those of eryptogenic epilepsy.The importance of febrile seizures( idiopathic:15.2％ ( 10/66 ),symptomatic:6.5％ ( 185/2834 ),cryptogenic:9.4％ ( 250/2672 ) ; x2 =181.393,P =0.000 ) and family history ( idiopathic:83.3％ ( 55/66 ),symptomatic:1.1％ (31/2834),cryptogenic:0.4％ (12/2672) ; x2 =68.354,P =0.000) was statistically different in different causes of epilepsy.Febrile seizures was the most frequent in cases with hippocampal sclerosis than those with other causes,and family history was the most frequent in neurocutaneous syndrome in symptomatic cases.Perinatal injurics was thc first causc in cases of infancy and childhood,head trauma was the top one in those of juvenile and adulthood,and cerebral vascular disease was the main cause in senile cases. Conclusions In the whole epileptic cases of 5572, 1％ was idiopathic,51％ was symptomatic,and 48％ cryptogenic. The main causes of them were head trauma,perinatal injuries,infection in central nervous system,brain tumor,and cerebral vascular disease.

Objectives We sought to determine the factors that predicted in-hospital heart failure(HF)in patients undergoing successful primary percutaneous coronary intervention(PCI)for ST-segment elevation myocardial infarction(STEMI). Methods The clinical and angiographic data were retrospectively reviewed in patients undergoing successful primary PCI for their ifrst STEMI. According to the occurrence of in-hospital HF, patients were divided into HF group and non-HF group. The incidence and predictors of in-hospital HF and its impact on prognosis were determined. Results A total of 834 patients were included, among them 94 patients (11.3%) were in the HF group and 740 patients(88.7%) were in the non-HF group. The mean age was (62.9±12.9) years and 662 patients (79.4%) were male. All-cause mortality at 30 days was signiifcantly higher in the HF group than in the non-HF group (24.5%vs. 1.5%, P<0.001). In Cox regression analysis, left anterior descending artery (LAD) as the culprit vessel (HR 2.173, 95% CI 1.12~4.212, P=0.022), ln 24 h NT-proBNP (HR 1.904, 95%CI 1.479~2.452, P<0.001), 24 h hsCRP≥11.0 mg/L (median) (HR 2.901, 95%CI 1.309~6.430, P=0.009) and baseline serum glucose (HR 1.022, 95%CI 1.000 ~ 1.044, P=0.046) were independent predictors of in-hospital HF. Receiver operator characteristic analysis identiifed 24 h NT-proBNP ≥ 1171 pg/ml (c=0.883, P < 0.001) and 24 h hsCRP ≥ 13.5 mg/L (c=0.829, P < 0.001) were the best cut-off values in discriminating in-hospital HF with a sensitivity and speciifcity of 92.5%and 76.8%for 24 h NT-proBNP, 86.0%and 77.0%for 24 h hsCRP, respectively. Even among patients with LAD as the culprit vessel, the incidence of in-hospital HF was only 0.4%in patients whose 24 h NT-proBNP was<1171 pg/ml and 24 h hsCRP was<13.5 mg/L;while the incidence of in-hospital HF was up to 60.9%in patients whose 24 h NT-proBNP≥1171 pg/ml and 24 h hsCRP≥13.5 mg/L (P<0.001). Conclusions The incidence of in-hospital HF was still high in STEMI patients even after successful primary PCI. Patients with in-hospital HF had poor prognosis. LAD as the culprit vessel, hsCRP, NT-proBNP and baseline serum glucose were independent predictors of in-hospital HF. Assessment and combined use of different serum biomarkers were effective methods to estimate the risk of in-hospital HF in STEMI patients undergoing primary PCI.

Objective:To investigate the effectiveness and feasibility of a 3D U-Net in conjunction with a three-phase CT image segmentation model in the automatic segmentation of GTVnx and GTVnd in nasopharyngeal carcinoma.Methods:A total of 645 sets of computed tomography (CT) images were retrospectively collected from 215 nasopharyngeal carcinoma cases, including three phases: plain scan (CT), contrast-enhanced CT (CTC), and delayed CT (CTD). The dataset was grouped into a training set consisting of 172 cases and a test set comprising 43 cases using the random number table method. Meanwhile, six experimental groups, A1, A2, A3, A4, B1, and B2, were established. Among them, the former four groups used only CT, only CTC, only CTD, and all three phases, respectively. The B1 and B2 groups used phase fine-tuning CTC models. The Dice similarity coefficient (DSC) and 95% Hausdorff distance (HD95) served as quantitative evaluation indicators.Results:Compared to only monophasic CT (group A1/A2/A3), triphasic CT (group A4) yielded better result in the automatic segmentation of GTVnd (DSC: 0.67 vs. 0.61, 0.64, 0.64; t = 7.48, 3.27, 4.84, P < 0.01; HD95: 36.45 vs. 79.23, 59.55, 65.17; t = 5.24, 2.99, 3.89, P < 0.01), with statistically significant differences ( P < 0.01). However, triphasic CT (group A4) showed no significant enhancement in the automatic segmentation of GTVnx compared to monophasic CT (group A1/A2/A3) (DSC: 0.73 vs. 0.74, 0.74, 0.73; HD95: 14.17 mm vs. 8.06, 8.11, 8.10 mm), with no statistically significant difference ( P > 0.05). For the automatic segmentation of GTVnd, group B1/B2 showed higher automatic segmentation accuracy compared to group A1 (DSC: 0.63, 0.63 vs. 0.61, t = 4.10, 3.03, P<0.01; HD95: 58.11, 50.31 mm vs. 79.23 mm, t = 2.75, 3.10, P < 0.01). Conclusions:Triphasic CT scanning can improve the automatic segmentation of the GTVnd in nasopharyngeal carcinoma. Additionally, phase fine-tuning models can enhance the automatic segmentation accuracy of the GTVnd on plain CT images.

Objective: To construct and validate a prognosis model related to ferroptosis in urinary tract tumors using bioinformatics methods. Methods: RNA-seq and clinical data from TCGA′s BLCA and KIRC datasets were analyzed to establish the prognostic model, and then were validated using ICGC and GEO data. Prognostic genes associated with ferroptosis were identified through univariate Cox, LASSO-Cox, and multivariate Cox regression analyses. Co-expression and protein-protein interaction(PPI) network analyses determined the relationships among these genes. Immune infiltration analysis explored the association between ferroptosis-related prognostic genes and the immune microenvironment. Functional enrichment analysis of differentially expressed genes between high and low-risk groups in BLCA and KIRC prognostic models was conducted to investigate potential mechanisms by which ferroptosis-related genes regulate BLCA and KIRC prognosis. Results: Significant prognostic gene signatures associated with ferroptosis were identified in BLCA and KIRC. For BLCA, the genes EGR1, ZEB1, P4HB, WWTR1, JUN, CDO1,SCD,SREBF1,CAV1, and GALNT14 were significant. For KIRC, the genes ASMTL-AS1, CHAC1,MT1G, RRM2, TIMP1, DPEP1, GLRX5, and NDRG1 were significant. Ferroptosis-related miRNAs linked to the prognosis of both cancers were also identified. The constructed risk models based on these genes and miRNAs predicted patient prognosis in TCGA-BLCA and KIRC, with low-risk groups showing significantly higher overall survival(P<0.05). The hazard ratios for these models ranged from 2.54(95%CI: 1.73-3.74) to 4.74(95%CI: 3.47-6.47), with AUC values above 0.60. Co-expression analysis and PPI networks revealed high correlation levels between JUN and EGR1 in BLAC and between SCD and SREBF1. Immune infiltration analysis indicated positive correlations between EGR1, CAV1, JUN, and immune scores, while SREBF1 showed a negative correlation. Conclusion The prognosis model based on ferroptosis-related genes effectively predicts patient outcomes in BLCA and KIRC. This model can serve as a reference for targeting ferroptosis to assess the prognosis of BLCA and KIRC patients.

Objective To explore the treatment methods of pediatric obstructive sleep apnea hypopnea syndrome (OSAHS).Methods A total of 386 children with OSAHS were enrolled from June 2008 to April 2011.Ninety children with adenoid and tonsil ≤ degree Ⅲ (group A) were randomly divided into A1 subgroup and A2 subgroup,while 22 of 296 (group B) children aged less than 3 years old with degree Ⅳ adenoid and(or) tonsil were divided into B1 subgroup,and the other 274 of 296 children with degree Ⅳ adenoid and (or) tonsil were divided into B1 subgroup,B2 subgroup and B3 subgroup.The adenoid,tonsil size examination and nasal endoscopic examination scores were performed before treatment,3 months and 6 months after treatment.Drug therapy included oral antibiotics,mometasone furoate as a nasal spray,leukotriene receptor antagonist (LTRAs),mucoactive medications.Conservative treatment meant drug therapy plus negative pressure of sputum aspiration.Surgical treatment meant coblation adenotonsillectomy.A1 subgroup received drug therapy for 3 months; A2 and B1 subgroup received conservative treatment for 3 months; B2 subgroup received coblation adenotonsillectomy after 3 days conservative treatment and postoperative drug therapy for 2 weeks; B3 subgroup received coblation adenotonsillectomy after 2 weeks conservative treatment and postoperative drug therapy for 3 months.Results The adenoid and tonsil size of A2 subgroup decreased at 3 months after treatment (Wald x2 were 10.584 and 8.366,respectively,P ＜ 0.05),no significant re-increase was found at 6 months,and no decrease was found in the A1 subgroup (P ＞ 0.05).The nasal endoscopic examination scores decreased in both A1 and A2 subgroup at 3 months after the treatment (F =403.420,P ＜ 0.05),but it was found re-increase in A1 subgroup at the 6 months (P ＜ 0.05),no significant re-increase was found in the A2 subgroup.The polysomnography (PSG) monitor of A2 subgroup was 100.0％ normal at 3 months after treatment,while the A1 subgroup was only 43.2％ (x2 =36.189,P ＜ 0.05).B2 and B3 subgroups cured after coblation adenotonsillectomy,but no decrease of the adenoid and tonsil size was found in B1 subgroup (P ＞ 0.05).The nasal endoscopic examination scores of B1,B2 and B3 subgroups showed significant decrease after the treatment,but re-increase was found in both B1 and B2 subgroups at the 6 months (F =1 614.244,P ＜ 0.05),no significant re-increase was found in the B3 subgroup.The PSG monitor of B3 subgroup was 100.0％ normal at 3 months after treatment,B2 subgroup 73.4％,and B1 subgroup only 57.4％ (x2 =90.846,P ＜ 0.05).Conclusions The treatment method of children with OSAHS should be selected according to the age,condition of disease,and size of the adenoid and tonsil.Adenoid and tonsil ≤ degree Ⅲ should select conservative treatment; while for degree Ⅳ adenoid and (or) tonsil,surgical treatment should be primary choice.Conservative treatment can reduce the risk of perioperative and adequate postoperative drug therapy can help prevent recurrence after surgery.

Objective:To analyze the clinical data of laryngeal airway diseases in infants and provide reference for the standardized diagnosis and treatment of the disease. Methods:From June 2022 to August 2023, analyze the clinical data of 4 cases of children with laryngeal airway diseases recently admitted to Department of Otolaryngology, Fuzhou Children's Hospital of Fujian Province, and summarize the experience and lessons of diagnosis and treatment by consulting relevant literature. Results:Three cases had symptoms such as laryngeal wheezing, dyspnea, backward growth and development, etc. After electronic laryngoscopy, the first case was diagnosed with laryngeal softening （severe, type Ⅱ）, and the angular incision was performed. While cases 2, 3 diagnosed with case 2 and 3 were diagnosed with laryngeal cyst and underwent laryngeal cyst resection. All three cases underwent low-temperature plasma surgery under visual laryngoscope, and the symptoms were relieved after operation. Case 4 was laryngeal wheezing and dyspnea after extubation under general anesthesia. The electronic laryngoscopy showeded early stage of globetic stenosis, and endoscopic pseudomembrane clamping was performed, and the postoperative symptoms were relieved. Conclusion:Infants and young children with laryngeal airway diseases should pay attention to the early symptoms and be diagnosed by electronic laryngoscopy as soon as possible. With good curative effect and few complications, low-temperature plasma surgery under visual laryngoscope is recommended. The formation of pseudomembrane under the gluteal caused by tracheal intubation causes rapid onset and rapid development. The pseudomembrane extraction by clamping is convenient and fast, with good curative effect.

Congenital laryngomalacia is the most common disease causing laryngeal stridor in infants. The pathogenesis has not yet been clearly concluded. It may be related to abnormal development of laryngeal cartilage anatomical structure, neuromuscular dysfunction, gastroesophageal and laryngeal reflux disease, etc. The typical manifestations of the disease are inspiratory laryngeal stridor and feeding difficulties, which can be divided into mild, moderate and severe according to the severity of symptoms. The diagnosis is mainly based on clinical symptoms, signs and endoscopy, among which endoscopy is an important diagnostic basis. The treatment of laryngomalacia depends on the severity of symptoms. Mild and some moderate congenital laryngomalacia children can be relieved by conservative treatment, and severe and some moderate congenital laryngomalacia children should be treated by surgery. Supraglottic plasty is the main surgical method, which can effectively improve the symptoms of laryngeal stridor, dyspnea, feeding difficulties and growth retardation in most children, and the surgical effect is good.
