Independent Crash Prevention on the ocean: A study.
Results The methylation rate of PTEN promoter region in tumor tissues (29.17%±9.58%) was significantly higher than that in paracancer tissues (4.17%±2.86%)(t=19.970,P less then 0.05). At the same time, in HCC tissues, the methylation rate of the PTEN promoter region is negatively correlated with its expression (F=47.270,P less then 0.000 1;Y=-1 800×X+38.03), and the PTEN methylation rate is negatively correlated with the prognosis of patients receiving the molecularly targeted drug Sorafenib (χ²=4.313,P less then 0.05). Conclusion This study successfully established a new method for detecting methylation in the promoter region of PTEN, and the methylation rate of PTEN can be used as one of the targets of HCC diagnosis and targeted therapy.Objectives To investigate the prevalence of cough and its influencing factors in community children under 5 years old. Methods From October to December 2019, we selected 3 102 community children under the age of 5 from 50 natural villages/residential communities in 14 towns/streets of Yiwu, Zhejiang Province, using multi-stage random sampling method. A face-to-face and on-site questionnaire survey was conducted among child caregivers to collect demographic data and information about children's cough in the last 1 month. Multiple logistic regression model was used to analyze children's cough and the influencing factors of different cough states. Results Multivariate logistic regression model analysis results showed that compared with 0-1 year old, dispersed, caregivers with education level below high school, families with 1 child under 5 years old, Cough risk was higher in 1-2, 2-3, 3-4 years old, nurseries, caregivers with education level of high school or above, and families with more than 2 children under 5 years old. OR (95%CI) values were 1.52(1.19-1.92), 1.65(1.29-2.10), 1.86(1.36-2.54), 2.59(1.99-3.38), 1.48(1.26-1.74) and 1.35(1.13-1.62), respectively. Further analysis of the influencing factors of different states of cough, multivariate logistic regression model analysis results showed that preschool status, the number of children under 5 years old in the family and the education level of caregivers were the influencing factors of acute, prolonged and chronic cough. Age was only an influencing factor of acute and persistent cough. Conclusions The disease burden of cough in children under 5 years old community was heavy, and the cough was related to children's age, education level of caregivers, number of children under 5 years old in the family and childcare status.Objective To establish the norm of the Chinese version of Karitane Parenting Confidence Scale (KPCS) in urban areas of China. Methods From August to December 2017, the parents of 2 216 children ( less then 36 months old) were selected from 15 cities (Beijing, Lianyungang, Hangzhou, Chengdu, Xi'an, Guangzhou, Changsha, Jinan, Guiyang, Ningbo, Dalian, Qinhuangdao, Maanshan, Chongqing and Wuhan) in 14 provinces by stratified random sampling. The general demographic characteristics and parents' parenting confidence were collected by a self-made questionnaire and KPCS Chinese version. The percentile norm was established. P3, P10 and P25 were used as the criteria to define the degree of lack of parenting confidence. Results The age of mothers was (30.67±4.29). The age of the father was (32.50±4.99) years old. There were 726 (32.76%), 759 (34.25%) and 731 (32.99%) infants in 6-12, 12-23 and 24-35 months old groups. The total scores of P50, P25, P10 and P3 of KPCS (Chinese version) of infant parents in urban areas in China were 41, 38, 33, and 29 respectively. When the scores of parents were 34-37, 30-33, and ≤ 29, they were judged as mild, moderate, and severe lack of parenting confidence. There was no significant difference in the Chinese version of KPCS between parents of different age groups and parents of different gender (χ²=3.53, P=0.171; χ²=1.41, P=0.236). Each factor score≤P3 is defined as the boundary score, and the corresponding boundary scores of "parenting" "support" and "competence" were 13, 9, and 5 respectively. Conclusion The Chinese version of KPCS can be used to assess the parenting confidence of infants in urban areas of China. It can used as one of the bases for scientific and objective evaluation of the parenting status of families.Objective To investigate the potential pleiotropism of cancer-related single nucleotide polymorphisms (SNPs) among Chinese population. Methods Based on the catalogue of GWAS jointly constructed by the National Human Genome Research Institute and the European Institute of Bioinformatics, according to population origin (Chinese population and non-Chinese population) and disease traits (cancer and non-cancer traits). All SNPs found by GWAS before August 2020 were divided into four categories cancer in Chinese population, non-cancer in Chinese population, cancer in non-Chinese population and non-cancer in non-Chinese population. The number, correlation and linkage of the four categories of SNPs were described. Results By August 2020, a total of 196 813 SNPs from 4 096 GWAS were included in the GWAS directory. The information that SNPs refer to unknown or were not related to the disease was excluded, and 117 441 independent SNPs were finally included. There were 619 SNPs related to cancer and 9 569 SNPs related to non-cancer disease in Chinese population, respectively. There were 4 624 SNPs related to cancer and 106 448 SNPs related to non-cancer disease (trait) in non-Chinese population, respectively. Three SNPs, rs2736100, rs6983267 and rs401681, were associated with two or more types of cancer in both Chinese and non-Chinese populations. Seven SNPs, rs7705526, rs2736100, rs10993994, rs2735839, rs4430796, rs174537 and rs9271588, were associated with cancer and non-cancer diseases in both Chinese and non-Chinese populations, respectively. Conclusion There is a potential pleiotropism of cancer-related SNPs in Chinese population.Objective To explore the effect of long-term exposure to ambient particulate matter (PM10) on the prevalence of diabetes and fasting plasma glucose (FPG). Methods The subjects of the study were from the baseline population of "Jinchang Cohort", and 24 285 subjects were finally included after excluding incomplete home address information and diabetic diagnosis information. The demographic characteristics, lifestyle and health status of the survey subjects were collected through questionnaire, physical examination and laboratory tests. ArcGIS software was used to match the nearest environmental monitoring stations for each subject according to residential address. Aminocaproic nmr Two-year average concentrations of PM10 were calculated to estimate exposure level. The logistic regression and the multiple linear regression were conducted to assess the effects of ambient PM10 on the prevalence of diabetes and FPG. The restricted cubic spline was used to quantify the dose-response relationship. Stratified analysis and effect modifis of PM10 on FPG were more significant in people older than 50 years[β (95%CI) = 0.080 (0.050-0.109) mmol/L], with family history of diabetes [β (95%CI) = 0.087 (0.036-0.137) mmol/L], and hypertension [β (95%CI) = 0.077 (0.046-0.108) mmol/L] (all P interaction values were less then 0.05). Conclusions Long-term exposure to ambient PM10 increases the diabetes prevalence and FPG. People older than 50 years old, with family history of diabetes and hypertension could be more sensitive to the effects of PM10 exposure.Objective To analyze the change of the number of staff at the provincial center for disease control and prevention (CDC) in China before and after the new health care reform. Methods The data was from publicly reported health statistics yearbooks from 2002 to 2018. Descriptive analysis and interrupted time series analysis (ITS) were conducted in Stata/SE 15. Results The decreasing trend of total number and average number of CDC staff per ten thousand people further exacerbated in the eastern and central areas after the new health care reform, while the total number of CDC staff in the western area changed from a decreasing trend to an increasing tend and the decreasing trend of average number of CDC staff per ten thousand people slowed down. After controlling the provincial and time fixed effects, the ITS analysis showed that before the reform, the number of CDC staff in central area showed a decreasing trend (P=0.012). After the reform, no statistically significant changes were observed in the number of CDC staff in the eastern, central and western areas increased instantaneously (P>0.05), and the decreasing trend (slope) of the number of CDC staff in the eastern and central areas further increased. The number of CDC staff in the western area changed to an increasing trend (P>0.05). Conclusion After the new health care reform, the total number and average number of CDC staff at the provincial level have not improved, therefore targeted reform strategies are needed to reverse the continuous reduction of CDC staff and reflect regional differences in the future.Objective To analyze the achievement of policy goals and actual changes of representative structure quality indicators related to disease control and prevention system during 2002-2018 in China. Methods Quantified policy goals of structure quality including the number of workers, the proportion with bachelor degree and working environment were extracted from relevant policy documents and the data about representative structure quality indicators, including finance, human resources and working environment, were extracted from health statistics yearbooks. Comparative analysis was adopted in this study. Results First, the designed policy goals were partly achieved. The number of workers per ten thousand people was lower than 1.75 in 2015. The target proportion of workers with bachelor degree was achieved by four year later in 2016. Only average building area per person was achieved according to the goal set in 2009. Second, it showed huge discrepancy among the proportion of financial subsidy, average personnel expenditure per person, and the number of workers at different levels of centers for disease control and prevention (CDC) from 2002 to 2018. The development of county-level CDCs was more restrained. Conclusion Appropriate policy goals regarding financial support, human resources, and working environment should be strengthened at national level and quality improvement strategies should be established in the CDC system, particularly for county-level CDCs.Objective To analyze the related polities about disease control and prevention system in China from 2000 to 2020, and to provide implication for the policy formulation of disease control and prevention system in the future. Methods Policy documents were searched in the official websites of relevant government departments including the State Council, National Health Commission, National Development and Reform Commission, Ministry of Human Resources and Social Security, and Ministry of Finance by using the keywords related to disease control and prevention from 2000 to 2020. Thematic framework and content analysis were performed to analyze the eligible policy documents based on the theory of policy instruments. Results A total of 37 policy documents were included in this study. The application of single policy instrument was common (81.1%), of which the capacity building instrument was the most frequently used (32.4%), followed by mandate instrument (21.6%) and inducement instrument (13.5%), while system-changing instrument (8.
