Abstract:
Objective To understand the current status and trend of the mortality of road traffic injury among children aged 0-14 years in different gender, age groups and provinces in China from 1990 to 2015, so as to make clusters and provide prevention and control strategies. Methods Data of road traffic injury mortality in China from 1990 to 2015 were collected from global disease burden 2015 to explore current status of road traffic injury among children aged 0-14 years and to calculate the relative change and the annual percent changes from 1990 to 2015. The potential number of clusters of provinces was analyzed by adopting k-median cluster analysis. Results In 2015, the mortality rate of road traffic injury in boys aged 0-14 years was higher than that in girls at the same age range. The mortality rate in the children aged less than 5 years old was higher than that in older age groups. From 1990 to 2015, there was a significant decline in the mortality rate of road traffic injury among children aged 0-14 years in different gender, age groups and provinces. The extent of decline was comparable between boys and girls, but higher in younger children. The highest and lowest extent of decline was observed in Hong Kong Special Administrative Region and Anhui Province respectively. There were four different clusters for all provinces according to the current status and trend of road traffic injury among children aged 0-14 years. Conclusions There was a significant decline in the mortality rate of road traffic injury among children aged 0-14 years in different gender, age groups and provinces in China from 1990 to 2015. However, road traffic injury is still a severe threaten for children in China. More attention should be paid on young boys in some provinces when conducting child road traffic injury intervention and control programs.

Abstract:
Objective To analyze the relationship between fine particulate matter and hospital daily outpatients with pediatric respiratory diseases in Shijiazhuang. Methods The data of meteorology, air pollution and the daily outpatients with pediatric respiratory diseases were collected during 2014-2016 in Shijiazhuang. Generalized additive model (GAM) extended Poisson distribution was used to examine the relationship between fine particulate matter and hospital outpatients with pediatric respiratory diseases in Shijiazhuang. According to the exposure-response relationship curve, piecewise linear regression was used for risk analysis. Results During the study period, the average annual concentration of PM2.5 in Shijiazhuang was 104.93 μg/m3 and the average number of daily hospital outpatients was 690 to the pediatric respiratory diseases. The exposure-response relationship suggested a nonlinear between PM2.5 and daily hospital outpatient visits. A larger increase in daily hospital outpatient visits was observed at lower concentration of PM2.5. An increase of 10 μg/m3 of PM2.5 (lag1)was significantly related to hospital outpatients with respiratory diseases and could increase the excess risk of 0.26%(0.14%-0.38%). By moving average concentration analysis, there was a cumulative lag effect between PM2.5 concentrations pediatric respiratory visits. The highest influence between PM2.5 and accumulative effects for pediatric respiratory diseases visits was occurred in lag 0-7. The analysis of multiple pollutants model showed that the effect of PM2.5 on the outpatient respiratory diseases decreased when only SO2 was introduced, and it was statistically significant. But there was no statistical significance when introducing other pollutants(all P>0.05). Conclusion The PM2.5 in Shijiazhuang may lead to the increase in hospital outpatients with pediatric respiratory diseases.

Abstract:
Objective To analyze the effect of air pollutants on gene expression profiles of peripheral blood in adults and children by bioinformatics research methods, so as to provide theoretical reference for future prevention, diagnosis and treatment. Methods A group of peripheral blood microarray data from children and adults exposed to different air pollution were downloaded from the gene expression omnibus (GEO) database. The data were analyzed by QOE, GenClip, GATHER and other data analysis software to identify the gene expression profiles, protein-protein interaction networks, molecular biology process and gene function, thereby to search key genes by which air pollution affects adults and children. Results In the same exposure source, key difference genes of the children were different from those of the adults'. The identified key genes of latter were mainly related to cell proliferation, chromosome modification, DNA metabolism and chromosome organization, while the genes of the former were mainly related to platelet activation, cell signal conduction, and organic physiological process. Further analysis revealed that FIGNL1, TUBB1, TPST1 and SAMHD1 genes were common genes in adults and children, and these genes were mainly related to tumor induction and inhibition. Conclusions Alteration in gene expression profile varies in adults and children who are exposed to the different air pollution levels. In the same exposure source, the difference genes between children and adults are also different. These common different genes are mainly related to the induction and inhibition of tumor.

Abstract:
Objective To investigate the sleep quality of college students from eight universities of Chinese medicine and analyze the possible influencing factors. Methods A stratified cluster sampling method was used to obtain 7 142 college students from 8 universities of traditional Chinese medicine in four regions of China. The Pittsburgh sleep quality index (PSQI) and a self-designed questionnaire were used to carry out a cross-sectional survey. Results Totally 6 534 valid questionnaires were retrieved, boys 1 778 (27.21%), girls 4 756 (72.79%); the mean age was (20.32±1.23) years. The mean score of PSQI was (4.58±2.30), detection rate of insomnia (PSQI ≥ 8) was 10.33%. The score of PSQI of students from cities (4.36±2.32) was better than those from villages and towns (4.64±2.29, t=-3.909, P<0.001). The score of PSQI of students who belonged to extroversion (4.50±2.38) and intermedius type (4.54±2.25) was better than those who belonged to introversion (4.78±2.35, F=6.481, P=0.002). The score of PSQI of students with normal weight(4.52±2.22) was better than those who were underweight (4.64±2.38), overweight (4.89±2.60) or obesity (5.03±2.60, F=5.892, P=0.001). There was no significant difference in PSQI score between different genders(t=-0.005, P=0.996). Multiple regression analysis showed that there were twelve factors which may influence college students' sleep quality like index of pressure, life satisfaction and regular dietary. Conclusions The sleep quality of students from universities of Chinese medicine which was influenced by many factors still needs to be further improved.

Abstract:
Objective To explore the association between peripheral inflammatory factor levels and cognitive performance in the older people with mild cognitive impairment population (MCI). Methods A case-control study was performed, consisting of 150 MCI patients and 101 healthy controls.The Wechsler Adult Intelligence Scale was revised in China (WAIS-RC) was used to assess the cognitive function. Serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and amyloid β-protein (Aβ) levels were measured by ELISA and Milliplex Map Cytokine Kit. Results The levels of serum IL-6 and Aβ42 in MCI group were both higher than those in control group (all P<0.05). Multiple linear regression showed there was significant correlation between the increase of Aβ42 level and the decrease of verbal intelligen quotient (VIQ) (β=-0.285, P<0.001). Elevated IL-6 and TNF-α levels were associated with the decrease of performative in telligence quotient (PIQ) and full intelligence quotient (FIQ) (all P<0.05). Conclusions Serum IL-6 and Aβ42 levels are increased in MCI patients. Serum levels of IL-6 and TNF-α could evaluate the performative and general intellectual impairment of MCI, and the level of Aβ42 could be used as an assessment factor of verbal intellectual impairment in MCI.

Abstract:
Objective To explore the correlation between cognitive impairment and mortality risk in Chinese elderly women. Methods Based on data from the Chinese Longitudinal Healthy Longevity Survey (2002-2011), Cox proportional Hazard Model was used to analyze the correlation between cognitive impairment and mortality risk, taking cognitive impairment as dependent variable, adjusting demographic variables (age, sex, residence, ethnic, marriage and education) and healthy variables (activity of daily living, hypertension, stroke and diabetes, as well as optimism and happiness). Results The mortality risk of cognition impaired group was 2.22 times that of control group (HR=2.22, 95% CI:2.08-2.37, P<0.001). After adjusting confounding factors, cognitive impairment was still related with high mortality risk among the whole sample (HR=1.14, 95% CI:1.05-1.22, P=0.001). There was a sex difference in rural areas. The correlation still existed among urban women (HR=1.21, 95% CI:1.08-1.36, P=0.001), the relation among rural women was not significant (HR=1.09, 95% CI:0.99-1.20,P=0.075). Conclusions Cognitive impairment is associated with high mortality risk in elderly women, and has a rural-urban difference. Intervening factors influencing the occurrence and development of cognitive impairment can play an important part in reducing mortality risk of the elderly and improving their health and quality of life.

Abstract:
Objective To investigate the psychology status of patients with diabetic retinopathy during preoperative period and its influencing factors. Methods A total of 86 diabetic retinopathy (DR) patients from the First Affiliated Hospital of Anhui Medical University were enrolled in the cross-sectional study, who were investigated by using general information questionnaire, diabetes distress scale (DDS) and self-rating anxiety scale (SAS). Among them, 49 patients underwent vitrectomy, 37 patients underwent vitrectomy and silicone oil filling. T test was used to compare the measurement data between groups, and rank sum test was used to compare the grade data. Logistic regression analysis was used to evaluate influencing factors of anxiety and pain. Results 56 participants with DR suffered psychological pain while the other 31 suffered anxiety. There was significant difference between the two groups in DDS and SAS (all P<0.05). The multifactor analysis showed treatment method (OR=3.116, 95% CI:1.036-9.372, P=0.043) was risk factor of distress. Female (OR=4.376, 95% CI:1.052-18.201, P=0.042), genetic history of the diabetes (OR=7.596, 95% CI:1.788-32.272, P=0.006) and treatment method (OR=12.742, 95% CI:3.609-44.983, P<0.001) were risk factors of anxiety. Conclusions Patients with DR who underwent vitrectomy and silicone oil filling are more prone to have pain and anxiety than those with simple vitrectomy. Evaluating psychological status of patients with diabetic retinopathy is significant to improve patient compliance as well as prevent and control complications.

Abstract:
Objective To investigate the prevalence and related influencing factors of chronic obstructive pulmonary disease in four disease surveillance points of Hubei Province. Methods A total of 2 400 residents aged over 40 years were surveyed through multistage clustering sampling method by questionnaire, body measurement, and pulmonary function test. Based on the complex sampling design, χ2 test and unconditional multivariate logistics regression analysis were conducted to identify the influencing factors of COPD. Results A total of 2 389 subjects aged over 40 years were recruited. The number of COPD patients was 213, accounting for 8.92%. The prevalence of COPD was 12.36% (95% CI:6.95%-17.77%). The prevalence of rural areas (13.96%) was higher than urban areas(9.04%), and the prevalence of men (17.47%) was higher than women(6.54%). The χ2 tests showed that the region, gender, age, SBP, BMI, and smoking were COPD-related factors (all P<0.05). The multivariate Logistic regression showed that compared with the age group of 40-49, the age group of 50-(OR=2.316, 95% CI:1.999-2.683), 60-(OR=4.641, 95% CI:2.479-8.687) and over 70 (OR=9.066, 95% CI:5.735-14.333) increased the risk of COPD. Smoking (OR=3.376, 95% CI:2.357-4.834) and using polluting fuels for household heating (OR=1.734, 95% CI:1.264-2.380) were risk factors for COPD. Compared with low body weight, people with overweight (OR=0.599, 95% CI:0.367-0.978) and obesity (OR=0.404, 95% CI:0.218-0.752) had lower risk of getting COPD. Conclusions Men from rural areas in Hubei had relatively high COPD prevalence. People who had elder age, smoking history, and been using polluting fuels for household heating had higher risk of COPD. Targeted intervening measures should be carried out for COPD prevention.

Objective To investigate the association between paternal-related factors and the susceptibility of childhood acute leukemia (AL). Methods Based on case-control study, AL children and their 1:1 controls matched with residential region, age and gender were recruited from four hospitals in Henan Province from 2014 to 2016. Propensity score matching (PSM) was used to equalize covariates, the matching effect was verified by standardized difference method. Conditional Logistic regression was used to analyze the association between variables and childhood AL with the matched data.The adjusted population attributable risk percent (PARP)and subgroup analyses were performed. Results A total of 407 cases and 407 controls were included in the analysis. A total 270 pairs of cases and controls were matched by PSM. The standardized difference values of 16 covariates were less than 0.1 after PSM. Conditional Logistic regression showed that paternal exposure to pesticides (ORadj=1.93, 95% CI:1.23-3.05), hair coloring (ORadj=2.31, 95% CI:1.04-5.12) 6 months before pregnancy increased the risk of childhood AL, of which PARP were 11.42%, 4.62% respectively. The relationship between paternal exposure to pesticides and childhood AL were still obvious in sub-population with male, age at diagnosis less than 5 years old, rural residents, and those with paternal exposure to tobacco (all P<0.05). Conclusion Paternal exposure to pesticides, hair coloring 6 months before pregnancy can increase the susceptibility of childhood AL, which should be controlled in prenatal care.

Abstract:
Objective To investigate the effect of co-stimulatory molecule B7-H4 on the regulation of T cell subsets in (NOD) mice induced by SjÖgren's syndrome (SS). Methods Female NOD mice were randomly divided into baseline group, normal saline (NS) group, B7-H4-Fc protein group, IgG2a-Fc group. After 0 days and 30 days, The mice were sacrificed after being anesthetized, and the spleen and submandibular glands were taken out. The changes of lymphocyte subsets in spleen single cell suspension were detected by flow cytometry, and the submandibular gland tissue was stained with HE and immunohistochemistry. Results Costimulatory molecule B7-H4 protein was mainly expressed in cytoplasm of submandibular gland ductal endothelial cells in NOD mice. A low expression of B7-H4 protein was found in a large number of lymphocytes infiltrated in the submandibular gland. The degree of inflammatory infiltration of submandibular gland in NOD mice was significantly reduced after intraperitoneal injection of B7-H4-Fc fusion protein at day 30. The percentages of CD4+Foxp3+Tcell/CD4+Tcell in spleen were significantly increased in B7-H4-Fc group compared with IgG2a-Fc group, NS group and baseline group respectively (all P<0.05). The percentage of CD4+IFN-γ+Tcell/CD4+Tcell in B7-H4-Fc group was significantly lower than that in IgG2a-Fc group, NS group and baseline group (all P<0.05). There was no significant difference in the proportion of CD4+IL-17+T cells in the spleen between the three groups in the proportion of CD4+T cells. Conclusions B7-H4 protein can delay the infiltration of lymphocyte in the submandibular gland of NOD mice, reduce the level of inflammatory cytokines and inhibit the progress of autoimmune inflammation.

Abstract:
Objective To clinically evaluate the safety and immunogenicity of the recombinant hepatitis E vaccine developed by Changchun Biological Products Research Institute Company Limited in a population aged 16 to 65 years old. Methods We first selected subjects who were HEV antibody negative as a target population by screening. Then, a single center, randomized, blind trial with a similar product as a parallel control was conducted that sixty 16-65 years old healthy subjects who were HEV antibody negative were randomized to receive study vaccines or controlled vaccines by the ratio of 1:1. The immunization schedule consisted of 3 doses given on month 0, month 1 and month 6. Adverse reactions/events within 28 days after each dose were recorded. Hepatitis E IgG concentrations were detected with blood samples collected before immunization and 1 month after full schedule. Results We recruited 369 subjects. Among them, 187 were hepatitis E antibody negative after screening, and 60 subjects were enrolled in the trial eventually. Overall incidence of solicited adverse effects after 3 doses vaccination in the test group and the control group were 43.33% and 40.00% respectively. Majority of the adverse effects were mild and moderate. The most common injection-site and systemic reactions were pain and headache. The occurrence rates of adverse effects were not significantly different between groups (all P>0.05). Seropositive rates of HEV antibody after vaccination in the test group and the control group were both 100% and GMCs were 72.53 U/ml and 87.49 U/ml respectively. Conclusion The test vaccine has good safety and immunogenicity and a phase Ⅱ clinical trial can be carried out.

Abstract:
Objective To evaluate and forecast the economic outcomes of the national hepatitis B immunoprophylaxis strategies from 2006 to 2030, and to promote a nationwide program eliminating hepatitis B launched early in China. Methods The decision analytic-Markov model was used with newborns from 2006 to 2030 as simulation cohort. The cost-effectiveness and cost-benefit analysis were assessed for different scenarios of the last decade and the next fifteen years. The costs and benefits were calculated from the health-care and societal perspectives. The net benefits (NB) and benefit cost ratio (BCR) were considered indicators of cost-benefit analysis. The numbers of hepatitis B virus(HBV)infection and the patients with HBV-related diseases prevented, cumulative quality adjusted life years (QALYs) and the costs per QALYs gained were calculated for cost-effectiveness analysis. Results From 2006 to 2015, the costs of the strategy from two perspectives were RMB 625.664 billion yuan and 812.503 billion yuan, respectively. However, the NB reached up to RMB 4 357.185 billion yuan and 5 370.380 billion yuan, with the BCR of 7.96 and 7.61, respectively. And the costs per QALYs gained were RMB 6 471.53 yuan and 10 023.55 yuan. A total of 96 million QALYs were gained for all birth cohorts. Although the costs with RMB 750.015 billion yuan and 1 029.086 billion yuan will be invested from 2016 to 2030, the more NB with RMB 7 272.935 billion yuan and 8 981.808 billion yuan, the larger BCR with 9.45 and 8.79 and the more QALYs with 137 million will be gained for the strategy implementing sustainably. Also,the RMB 5 398.36 Yuan and 8 389.38 Yuan will be the costs per QALYs gained. Conclusions The national hepatitis B immunoprophylaxis strategies implemented in the last 10 years are with high value of cost-benefit and cost-effectiveness. The strategies will be gained more in the future 15 years, so as to respond the world health organization(WHO)advocacy for eliminating hepatitis B in China.

Abstract:
Objective To describe the current status of drinking water quality among centralized water supply units in China, so as to provide evidence for improvement of drinking water condition in China. Methods Data were extracted through the National Health Inspection Information System from 2013 to 2016, China Health Statistics Yearbook and China Statistics Yearbook. Descriptive statistics were conducted to analyze the distributions of unqualified centralized water supply units. χ2 test were performed to determine the statistically significant difference of the unqualified rate. Results During 2013-2016, the annual unqualified rate of centralized water supply units were 1.84%, 2.73%, 2.56% and 2.74% in China, respectively. Unqualified rates for each category of centralized water units showed statistically significant difference (all P<0.001)in 2016. Unqualified rate of public water supply in rural areas (3.85%) was higher compared to urban (1.74%) and self-built facilities (1.33%). Unqualified rate in small and medium-sized (2.40%) water supply units was higher than that in large-sized (0.94%) ones. Areas with high average temperature and annual precipitation had high unqualified rates of centralized water supply units. The unqualified rate was higher in summer (2.06%) and autumn (2.60%). Western regions (4.80%) and southern areas (4.01%) had higher unqualified rate. Conclusion Unqualified rates of centralized water supply units depended largely on seasons and areas. Most unqualified units were small and medium-sized water supply units and located in rural areas.

Abstract:
In recent years, the research on hantavirus gene is getting deeper and deeper with the development of molecular biology and other technologies. A lot of research on different types of hantavirus and rodent hosts, ecological environment and evolution has been carried out at home and abroad. It was found that the prevalence and evolution of hantavirus were closely related to the long-term interaction between hantavirus and hosts.Hantavirus has many genotypes and it is widely distributed all over the world. There were differences in nucleic acid sequence among different serotypes of hantavirus and different hantavirus strains of the same serotype, and the gene fragments of hantavirus of different genotypes were often recombined, which plays an important role in the interaction between hantavirus and host genes. Meanwhile, it is of great significance to the pathogenicity of hantavirus and the clinical diagnosis, treatment and epidemic of the related diseases. Therefore, in this study, the current epidemic status, biological characteristics and interaction with host genes of hantavirus were reviewed.
