Objective To assess the safety and influence of the stents extended into inferior vena cava in patients with non-thrombotic iliac vein lesions (NIVLs) on the bilateral iliac vein blood flow.Methods We retrospectively reviewed data from July 2008 to June 2017 in 197 patients with NIVLs who underwent iliac vein stenting and complete follow-up was obtained at our institution.Of these patients,stents extended into IVC more than 10 mm in 141 cases,less than 5 mm in 22 cases,and 34 cases were between 5 and 10 mm.Restenosis and thrombosis of bilateral iliac vein and patency of these stents were assessed in the follow-up.The count data were expressed by percentage (%),and the sample comparison rate was analyzed by Fisher exact test formula.The measurement data were first tested for normal distribution and homogeneity of variance,and then corrected t test.Results The two hundred and five iliac vein stents were placed in 197 patients.During a mean follow-up of 58.7 months (6 to 98 months),there were no thrombosis occurred in the contralateral iliac vein,6 patients suffered restenosis or new thrombosis in the stents,the incidence between stenting positions less than 5 mm (13.6%,3/22) and those more than 5 mm (3.43%,6/175) was sighificantly different (P <0.001),and 5 of 6 patients had a good patency after endovascular therapy.During the fllow-up,the primary and assisted-primary patency rates were 97.0% and 99.5%.Conclusions From these data,it appears that there is a very high patency rates of the stenting treatment for the NIVLs,and it is safe for the stents extended into the IVC,stenting across the iliocaval confluence can result in a small number of new contralateral thromboses.Moreover,the risk of stents restenosis or occlusion is high when stents are not extended into IVC.

Objective:
To investigate the snoring status of school-aged children in Beijing and explore the association of snoring and academic performance.
Methods:
A total of 7 925 children aged from 6 to 14 were selected from 15 primary and middle schools at 7 districts (Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou) in Beijing in 2015, using multi-stage stratified cluster random sampling method. The recruited children were asked to complete the Pediatric Sleep Questionnaire (PSQ) and a questionnaire related to sleep behavior. The multiplelogistic regression was used to analyze the association of snoring and academic performance.
Results:
A total of 794 (12.44%) children showed a decline in academic performance among 6 383 eligible respondentsfor data analysis. 580 (9.08%) children with snoring was identified, of which 333 and 247 were in frequency of 1-2 times per week and frequency of ≥3 times per week, respectively; 357, 170 and 53 were in snoring grade Ⅰ, grade Ⅱ and grade Ⅲ, respectively. Compared with the children without snoring, the

OBJECTIVETo analyze the surgical management of incidental gallbladder cancer (IGBC) discovered during or after laparoscopic cholecystectomy (LC) and to evaluate the associated factors of survival.
METHODSA retrospective analysis of patients with IGBC between January 2002 and December 2013 was performed. A total of 10 080 consecutive patients underwent LC operation for presumed gallbladder benign disease in Chinese People's Liberation Army General hospital. And among them, 83 patients were histologically diagnosed as IGBC. Data covering clinical characteristics, surgery records, local pathological stage, histological features and factors for long term survival were reviewed. The survival analysis was performed using Kaplan-Meier method, and the results were examined using the log-rank test.For multivariate statistical analyses of prognostic factors, a Cox proportional hazards model was carried out.
RESULTSA total of 83 patients with IGBC:68.7% females (57/83), median age of 61 years (range 34-83 years). There were 47 cases accepted the initial simple LC, 18 cases converted to open extended radical cholecystectomy, 16 cases with radical second resection, and 2 cases with re-laparotomy; the 5-year survival rates for each group were 89.4%, 38.9%, 87.5%, and 0, respectively. The 5-year survival rates in T1a, T1b, T2, and T3 stage patients were 95.7% (22/23), 90.0% (18/20), 75.0% (15/20), and 40.0% (8/20), respectively. Univariate analysis for prognostic factors associated with cancer-specific death showed that depth of invasion, lymph-node status, vascular or neural invasion, tumor differentiation, extent of resection, bile spillage during prior LC and type of surgery were statistically significant.In multivariate analysis, depth of invasion, extent of resection and bile spillage were the most important prognostic factors related to both cancer-specific mortality and disease relapse (P < 0.05).
CONCLUSIONSSimple LC is appropriate for T1a patients with clear margin and unbroken gallbladder. An extended radical resection in patients with T1b or more is highly recommended, and provided as a potentially curative R0 resection only if it is necessary.

Chinese Journal of Otorhinolaryngology Head and Neck Surgery 2019;54(12):902-906
Objective:
To investigate the snoring status and related family factors of children from 3 to 14 years old in Beijing.
Methods:
From May to July, 2015, data of children from 3 to 14 years old were obtained from a status survey from 7 districts(Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou) in Beijing. A total of 11 420 children from 25 primary and middle schools were randomly selected. Pediatric Sleep Questionnaire (PSQ) and a self-administered questionnaire were carried out for the adopted children. Self-administered questionnaire included the snoring related family factors. Logistic regression was used to estimate the odd ratio(OR) with 95% confidence intervals for variables.
Results:
A total of 9 198 children meet the inclusion criteria and are analyzed in the study, of whom 901 (9.80%) were found with snoring behavior. The incidence of boys is higher than girls. Obese children take higher risk of snoring. Compared with younger children (≤6 years old), older children (≥12 years old) have a significantly lower risk of snoring (

Objective:
To investigate the sleep quality of children in Beijing and to analyze the related factors.
Methods:
The data were collected from the survey of 3-14 years old children in 7 urban districts of Beijing in 2015. By using multi-stage stratified cluster random sampling method, 26 kindergartens and primary and secondary schools in 7 districts and counties, including Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou, were randomly selected, with a total of 11 420 children. Children′s sleep status was investigated with Children′s Sleep Questionnaire (PSQ), and the proportion of children with sleep quality problems when the PSQ score was greater than 7. Various sleep related factors were investigated with self-made questionnaire. A multilevel model was used to analyze the relationship between PSQ score and related factors.
Results:
The average PSQ score of the children was 3.60±2.69. The proportion of children with sleep quality problems was 8.87%(816/9 198). Multilevel model analysis showed that the younger the children, the higher the PSQ score (<6 years old
