RESUMO
@#Abstract: Objective To further investigate the underreporting of mortality surveillance data among permanent residents in Hainan Province in 2020, and to explore the application of Application of the Analysis of National Causes of Death for Action (ANACONDA) in the quality analysis of mortality surveillance. Methods The data were collected from the Death Information Monitoring and Management System of Hainan Center for Disease Control and Prevention, and mainly included 33 418 deaths reported from 19 cities and counties in Hainan Province from January 1, 2020 to December 31, 2020. All the data were analyzed by the application of ANACONDA, and the causes of death were classified by the International Classification of Diseases, 10th Revision (ICD-10). Results A total of 33 418 deaths were reported in Hainan Province in 2020, with a crude mortality rate of 3.6‰. The proportion of deaths in males under 85 years old was higher than that in females, while the proportion of deaths in 85 years old and above was opposite. The quality analysis of cause of death surveillance showed that there was under-reporting of death surveillance in Hainan Province in 2020, with an under-reporting rate of 30.1%. There were differences in the age composition and GBD regional composition ratio of deaths of the three major categories of diseases, and the misreporting of causes of death in the middle and high age groups was more significant. The Vital Statistics Performance Index (VSPI) score of death data in Hainan Province in 2020 was 52.8, the score of cause of death reporting quality was 85.5, and the score of specific cause of death level that could be used was 88.4. The completeness of death reports in the priority action areas for improving cause of death data quality accounted for the largest share, followed by the quality of cause of death reports. There was a difference in the proportion of specific causes of death between males and females after the survey, but the change in order was not obvious. Conclusions The data integrity of cause-of-death surveillance is low in Hainan Province in 2020. It is suggested to improve the completeness of reporting data, strengthen the training of cause-of-death surveillance system, and regularly evaluate and supervise the system.
RESUMO
@#Abstract: Objective To understand the general situation of death causes of permanent residents in Hainan Province from 2014 to 2020, analyze the causes of death, and provide scientific basis for the formulation of policies related to healthy Hainan. Methods The Hainan Provincial Population Death Information Registration and Management System was used to report data, and the death information of permanent residents in Hainan Province from 2014 to 2020 was obtained. Excel 2010 and SPSS 26.0 software were applied to perform statistical analysis related to the indicators including crude mortality rate, standardized mortality rate, ranking of causes of death, and composition ratio; the standardized mortality rate was calculated based on the data of the 2010 National Census Data. Results From 2014 to 2020, the average annual resident population of Hainan Province was 9 175 300, and average annual resident population at each of the eight monitoringp oints is 297 100， anaverage of 83 878 cumulative deaths were reported, the annual total mortality rate was 504.09/100 000, the standard mortality rate was 618.69/100 000. The standardized mortality rates of male and female were 806.18/100 000 and 444.36/100 000 respectively (P<0.01). The mortality rate of all age groups showed that the crude mortality rate of 0~<1 years old group showed a decreasing trend with the passage of time, and the crude mortality rate was significantly higher than that of other age groups. From the age of 20, with the increase of age, the overall crude mortality rate of residents keeps increasing. The crude death rate increases rapidly after the age of 65, and peaks especially after the age of 85. The leading causes of death were circulatory diseases, tumors and respiratory diseases. From 2014 to 2020, the mortality rate of circulatory diseases and tumors, the two main causes of death, was more than 100/100 000. Conclusion Chronic non-communicable diseases are still the first cause of death among permanent residents in Hainan Province. Targeted intervention and treatment of chronic non-communicable diseases is beneficial to reduce their mortality.
RESUMO
The aim of this paper was to observe the effect of triptolide( TP) on cardiovascular function and its possible mechanism by intraperitoneal injection of bacterial lipopolysaccharide in rats with endotoxemia. Sixty male Sprague-Dawley rats were randomly divided intonormal group( NC group),endotoxemia model group( LPS group),TP low concentration intervention group( LPS + TP-L group,25 μg·kg~(-1)),TP middle concentration intervention group( LPS+TP-M group,50 μg·kg~(-1)),TP high concentration intervention group( LPS+TP-H group,100 μg·kg~(-1)) and polymyxin B group( LPS+PMX-B group,0. 2 mg·kg~(-1)). 10 mg·kg~(-1) LPS was injected intraperitoneally for 6 h to replicate the endotoxemia rat model. The rats in TP intervention groups were pre-treated 15 min before intraperitoneal injection of LPS. Rats in each group underwent total arterial intubation to measure hemodynamic parameters: heart rate( HR),left ventricular diastolic pressure( LVDP),the maximum rate of the increase/decrease of left ventricular pressure( ±dp/dtmax). The levels of BNP,CK-MB and c Tn-Ⅰ in serum and levels of TNF-α and IL-6 in plasma were detected by ELISA. The contents of p65 protein in myocardium and contents of p65,TLR4,i NOS and e NOS protein in thoracic aorta were detected by Western blot. As compared with NC group,the hemodynamic indexes in LPS group were significantly decreased; the contents of BNP,CK-MB and c Tn-Ⅰ in serum,TNF-α and IL-6 in plasma,p65 in myocardium,i NOS,e NOS,TLR4 and p65 in vascular tissues were significantly increased. As compared with LPS group,the hemodynamic indexes were significantly improved in LPS+TP-M group,LPS+TP-H group and LPS+PMX-B group; the contents of BNP,CK-MB and c Tn-Ⅰ in serum,TNF-α and IL-6 in plasma,p65 in myocardium,i NOS,e NOS,TLR4 and p65 in vascular tissues were significantly decreased in each treatment group. Triptolide has a protective effect on cardiovascular damage in a dose-dependent manner in endotoxemia rats,probably through TLR4/NF-κB p65 signaling pathway to improve endothelial function.
