Objective To understand the epidemiology and trends of of unintentional injury deaths of children <5 years of age in Suzhou during 2016-2020 and to provide injury prevention and policy implications basis. Methods Surveillance data of children <5 years of age in 2016-2020 were collected，descriptive analysis and Chi-square test were used to analyze the epidemiological characteristics of injury deaths among children. Results The death rate of unintentional injury deaths demonstrated decreased from 80.17/100 000 in 2016 to 77.84/100 000 in 2020; The proportion of drowning and traffic accidents in migrant children was significantly higher than local children（χ²=16.44 , χ²=5.284 , P＜0.05）. The three leading causes of unintentional injury deaths were drowning (2.30/10000), suffocation (1.90/10000), and traffic accidents (1.42/10 000). Drowning among boys was 8.74 per cent, which was significantly higher than in girls（χ²=9.36，P＜0.05）. Drowning was the leading cause in boys, while suffocation was the leading cause of accidental death in girls. Accidents accounted for 57.49% of all deaths among children aged 1 to 4 years. Suffocation was the leading cause in children <1 year of age, but drowning（38.62%）was more prominent in children 1-4 years of age. Suffocation has high incidence in the winter, and drowning has high incidence in the summer season（P＜0.05）. Conclusions Effective childhood injury prevention may require different prevention policies combination depending on epidemiological characteristics such as genders, age groups，household register and seasons. The prevention programs should be carried especially the floating population.

Objective To understand the relative survival rate of cervical cancer patients in our hospital in the past 5 years, and to predict the relative survival rate in the next 5 years. The study can provide data information and scientific basis for cervical cancer prevention and treatment in Changde City. Methods According to the tumor registration database of our hospital, the 5-year relative survival rate of cervical cancer patients from 2010 to 2014 was evaluated by the cycle analysis method, and further stratified analysis was carried out according to the age of diagnosis and the township area. By establishing a generalized linear model based on the cycle analysis method, we predict the 5-year relative survival rate of patients in the future 2015-2019 period. Results From 2005 to 2019, the incidence of cervical cancer was the highest in the 45-54 age group, accounting for 40.54%. The incidence of cervical cancer was the lowest in the age group over 74, accounting for 2.72%. From 2010 to 2014, the overall 5-year relative survival rate of cervical cancer patients in our hospital was 92.73%, and the 5-year relative survival rates of patients <45, 45-54, 55-64, 65-74, and >74 years old were 93.51%, 92.82%, 89.16%, 85.71% and 63.83%, respectively. The 5-year relative survival rates of urban and rural patients were 94.73% and 91.86%, respectively. It is predicted that the overall 5-year relative survival rate from 2015 to 2019 is 93.78%. Conclusion Compared with the previous second 5-year periods, the 5-year relative survival rate of patients in the future 2015-2019 will still show an upward trend, the age difference gradient will continue to be maintained, and the urban-rural difference will further decrease.
