Objective To analyze the current situation and the trend of the death due to foreign body in airway in children less than 5 years old in China from 1990 to 2017. Methods Using the mortality data of foreign body in airway in China from 1990 to 2017 from the Global Disease Burden 2017 (data covered 31 provinces, autonomous regions, municipalities, as well as Hong Kong and Macau Special Administrative Regions, excluding Taiwan Province) to describe the death status of children under 5 years old due to foreign body in airway in China, and to calculate the relative change and 95% uncertainty interval ( UI ) of mortality rate and proportion of children under 5 years old due to foreign body in airway between 1990 and 2017. The robust linear regression was performed with the first?order lag of mortality, and the supremum Wald test was used to explore whether the mortality trend had obvious structural changes around a certain time point. Results In 2017, the mortality rate of children under 5 years old due to foreign body in airway in China was 8.57/100 000 (95%UI : 7.41/100 000-9.57/100 000), and there was no significant difference between boys (9.05/100 000, 95%UI : 6.82/100 000-10.23/100 000) and girls (8.02/100 000, 95%UI : 7.02/100 000-9.12/100 000). The supremum Wald test showed that there was a structural change around the year of 2005 (P<0.001) in terms of the mortality rate of foreign body in the airway among children under 5 years old, which depicted a relatively stable trend before 2005 and a significant downward trend after 2005. Compared with 1990, the mortality rate of foreign body in airway among children, boys and girls under 5 years old in 2017 decreased by 49.32% (95%UI : 37.78% - 65.41%), 41.22% (95%UI :25.68%-68.26%) and 56.91% (95%UI: 44.78%-66.70%), respectively; the mortality proportion of foreign body in airway among increased by 153.33% (95%UI : 75.99% - 204.56%), 171.05% (95%UI :48.75%-239.63%) and 137.90% (95%UI: 86.62%-198.09%), respectively; the rank of foreign body in airway in all disease increased by 6 and became the first leading cause of injury from the second. Conclusion From 1990 to 2017, the mortality rate of foreign body in airway among children, boys and girls under 5 years old in China generally showed a downward trend. Compared with 1990, the mortality proportion of foreign body in airway among these population increased by a relatively large extent in 2017.

Objective To investigate the mental health status of middle school students in Three-Gorge area in Chongqing, and to explore the relationship with their life events and coping styles. Methods The Compi-ling of mental health scales for middle school students(MSSMHS),adolescent self-rating Life events checklist and trait coping style questionnaire(TCSQ) were adopted in the study to test the randomly sampled 1 632 middle school students in Three-Gorges area in Chongqing. Results The rate of mental disorder in the samples was 27.5%. The total average scores and each factor of the mental health were positively correlated with the factors of life events(r=0. 29～0.55). Negative coping styles were positively correlated with the total average scores and each factor of the mental health (r=0.38～0.56). Positive coping styles was negatively correlated with anxiety, depression, study pressure(r=-0.07～-0.05). The factors of life events and coping styles explained 27%～49% variation of scores of the mental health total average scores and each factor of the mental health. Conclusion Both life events and the coping styles are the important factors for the mental health of middle school students in Three-Gorge area in Chongqing. Reducing negative life events and coping styles benefits the mental health of middle school students.

Objective To evaluate the clinical value of epicardial echocardiographic examination in cardiac valve surgery.Methods Epicardial echocardiography were performed in 46 patients undergoing valvular plasty or valvular replacement surgery to estimate the function of valve and left ventricle and residual shunt during cardiac surgery.Results Twelve cases of 46(26.1％)showed abnormality during cardiac surgery.Two cases of 15 patients performed valvuloplasty were changed to valvular replacement because of remarkable regurgitation of native valves.There was 1 case of periprosthetic leakage,3 cases of left atrial appendage thrombus,1 case of patent foramen ovale and 5 cases of low ejection of left ventricle in all 31 cases of valvular replacement.Conclusions Epicardial echocardiograpyc examination is an effective examination in cardiac valve surgery with clearly image,simplicity operation and promptness.

Objective To detect the expressions of Y-box-binding protein-1(YB-1)and epithelial-mesenchymal transition(EMT)markers(E-cadherin and N-cadherin)in colorectal cancer(CRC),to analyze the relationship between the expression of YB-1 and clinicopathological parameters,to evaluate the correlations among YB-1,E-cadherin and N-cadherin. Methods The expressions of YB-1,E-cadherin and N-cadherin in 120 primary CRC tumors and corresponding normal tissues were detected by western blot and immunohistochem-istry and the results were analyzed. Results The expressions of YB-1,E-cadherin and N-cadherin in tumors were significantly different from those in corresponding normal tissues(χ2 = 47. 373,P ﹤ 0. 05;χ2 = 83. 145, P ﹤ 0. 05;χ2 = 41. 832,P ﹤ 0. 05). The expression of YB-1 in tumors was associated significantly with tumor differentiation,tumor invasion,lymph node metastasis and distance metastasis(χ2 = 8. 077,P = 0. 008;χ2 =8. 178,P = 0. 006;χ2 = 15. 152,P ﹤ 0. 001;χ2 = 7. 368,P = 0. 011). It was negatively correlated with E-cadherin expression(r = - 0. 238,P = 0. 009),but positively correlated with N-cadherin expression(r =0. 361,P ﹤ 0. 001). Conclusion YB-1 may promote the occurrence and development of CRC by participating in EMT program.

Objective:To investigate the value of quantitative electroencephalography (qEEG) in the evaluation of thrombolytic efficacy in acute cerebral infarction.Methods:A prospective cohort study was conducted. Ninety-four patients with acute cerebral infarction who received intravenous thrombolysis admitted to the department of emergency of Qinhuangdao First Hospital from October 2019 to September 2020 were enrolled. The relative energy values of δ, θ, α and β waves in qEEG before and 2 hours, 24 hours and 7 days after intravenous recombinant tissue plasminogen activator (rt-PA) thrombolysis were dynamically monitored, and the power ratio index [DTABR, DTABR = (δ+θ)/(α+β)] was calculated. The National Institutes of Health stroke scale (NIHSS) score was also recorded. The reduction of NIHSS score ≥ 3 or the disappearance of neurological symptoms were regarded as effective thrombolytic therapy. The changes of DTABR before and after thrombolysis in patients with effective and ineffective thrombolysis were analyzed, and the correlation between DTABR and NIHSS score was analyzed by Pearson method.Results:A total of 94 patients were enrolled, including 64 males and 30 females. The average age was (61.71±10.11) years from 36 to 89 years old. Thrombolysis was effective in 57 cases and ineffective in 37 cases. Compared with before thrombolysis, DTABR of the effective group was significantly decreased at 2 hours, 24 hours and 7 days after thrombolysis (left cerebral infarction: 1.87±1.45, 1.59±0.88, 1.58±0.90 vs. 3.82±2.60; right cerebral infarction: 1.55±0.57, 1.41±0.50, 1.35±0.44 vs. 3.20±1.63, all P < 0.05). DTABR did not change or increase significantly at 2 hours, 24 hours and 7 days after thrombolysis compared with before thrombolysis (left cerebral infarction: 3.56±2.57, 3.48±2.19, 3.54±2.50 vs. 3.11±1.62; right cerebral infarction: 5.29±3.93, 5.33±3.94, 5.19±4.52 vs. 4.73±2.43, all P > 0.05). Pearson correlation analysis showed a significant positive correlation between DTABR and NIHSS score in patients with acute cerebral infarction (r = 0.691, P < 0.01).Conclusion:The quantitative index of qEEG, DTABR, can accurately and quickly monitor the process of thrombolysis in acute cerebral infarction, and can effectively evaluate the effect of thrombolysis in patients.

Objective To describe the epidemiological characteristics of suicide death and self?harm/suicide in China from 2006 to 2016. Methods Data in this study are from the datasets of National Death Cause Surveillance from 2006 to 2016 and the National Injury Surveillance Dataset 2016. The age?standardized death rate based on the population census in 2000 was used to describe the trend of suicide over years. This study also described the epidemiological characteristics of suicide death and the demographic characteristics, suicide methods and severity of patients who sought medical help after committing suicide or self?inflicted injury in 2016. Results Age?standardized suicide mortality had been declining from 9.23/100 000 in 2006 to 5.33/100 000 in 2016 by 42.25%. Suicide mortality increased with age. In 2016, the suicide mortality in China was 7.05/100 000, and among people over 85 years old was 49.49/100 000. In 2016, the dominant two suicide methods were poisoning (39.12%) and sharp injury (25.62%). The first leading method of suicide in rural population, urban population and young people aged 10?to 17?year?old was poisoning (65.13%), sharp injury (29.90%) and fall (25.47%), respectively. As age increased, the severity of suicide/self?inflicted injury increased. The proportions of serious cases among young people aged 10?to 17?year?old and older people aged 60 years old and above who sought medical help after committing suicide or self?inflicted injury were 4.88% and 26.86%, respectively. Conclusion China's suicide mortality has been declining and special attention should be given to the suicide of old people.
