ABSTRACT
Objective@#To understand the incidence and mortality of drowning and secular trend among children aged 0-14 from 1990 to 2019 in China, so as to provide reference for drowning intervention among children in China.@*Methods@#Based on data of drowning incidence and death in 0-14 years old children in China in 1990-2019 years Global Burden of Disease (GBD 2019) database, the standardized rate was calculated by the world standard population, and the trend of incidence rate and mortality rate was fitted by Joinpoint regression model respectively.@*Results@#From 1990 to 2019, the overall incidence of drowning among children aged 0-14 years in China decreased from 37.17/100 000 to 12.54/100 000, a relative decrease of 66.26%; the standardized incidence rate decreased from 21.78/100 000 to 14.98/100 000, a relative decrease of 31.22%. The incidence rate and standardized incidence rate of drowning in children showed an increasing after decreasing trend, with decreasing mortality and standardized mortality rate. Joinpoint regression showed that the incidence rate of standardized AAPC for child drowning was -1.3, -2.5 for males and 0 for females. The overall standardized mortality rate of drowning was -3.9, male was -3.6, female was about -4.5 , the trend changes were statistically significant ( P <0.05). The incidence rate and mortality rate of male were higher than that of female, and there was significant difference between male and female groups ( P <0.05).@*Conclusion@#Significant progress has been made in child drowning prevention and control, with substantial decreasing in the incidence rate of child drowning. However, considering recent slight increase in drowning incidence, effective measures should be developmed including risk factors, vulnerable population to further control the incidence and mortality of child drowning.
ABSTRACT
Objective@#To understand pneumonia mortality in children aged 0-14 years in China in recent 15 years, and to provide reference for child pneumonia prevention and treatment.@*Methods@#Based on the death data from China Statistical Yearbook 2005-2019, pneumonia mortality in urban and rural children aged 0-14 was extracted and the standardized mortality was calculated, and the trend of mortality was fitted by Joinpoint regression model.@*Results@#The crude mortality rate of child pneumonia in urban and rural areas showed an increasing trend, while the standardized mortality rate showed a fluctuating downward trend. Joinpoint regression showed that the mortality rate of pneumonia in urban and rural children showed a monotonous downward trend, and there was no turning point. The overall APC of pneumonia mortality of urban children was -3.4, that of boys and girls were both -3.5. Trend for annual changes in urban areas were found significant among total sample and boys (both P <0.05). The overall APC of pneumonia mortality in rural children was -7.8, that of boys and girls were -7.1 and -7.8, respectively. Trend for annual changes in rural areas were found significant among total sample and boys(both P <0.05). There was no significant differences in the trend of mortality between urban and rural groups.@*Conclusion@#During 2005 to 2019, child pneumonia mortality in urban and rural areas in China shows a downward trend, which is relatively balanced in urban and rural areas. Further strengthened pediatric pneumonia treatment and management are expected to reduce the pneumonia mortality.
ABSTRACT
Although the B-cell translocation gene 1 (BTG1) plays an important role in apoptosis and negatively regulatescell proliferation, BTG1 expression in skin squamous cell carcinoma (SCC) has not been reported. In this study,we wanted to investigate the significance of BTG1 expression in SCC and adjacent tissues. The expression ofBTG1 protein and mRNA in SCC tissues and adjacent tissues were detected by immunohistochemistrytechnique (IHC), Western blot and reverse transcriptase-polymerase chain reaction (RT-PCR). IHC stainingshowed that the positive expression rate of BTG1 protein in SCC tissues was 54.00%; and the positive rate was90.50% in the adjacent tissues. Western blot showed that the expression of BTG1 protein in SCC tissues wassignificantly lower than that in the adjacent tissues (P\0.05). RT-PCR showed that the positive rate of BTG1mRNA in SCC was 50.50%, which was significantly lower than that in adjacent tissues 89.00% (P\0.05).Both BTG1 mRNA and protein expression are related to tumor diameter, stage, tumor metastasis and thedegree of tumor differentiation in SCC. Patients exhibiting lower BTG1 protein expression in the SCC tissueshad a significantly shorter disease-specific survival rate. BTG1 protein expression, tumor diameter, tumors siteand stage were independent factors affecting the overall survival of postoperative patients. Further, BTG1overexpression inhibited A431 cell proliferation ability, while BTG silencing enhanced A431 cell proliferationability. The lower expression of BTG1 in SCC may be associated with the occurrence, development andprognosis of SCC.
ABSTRACT
Objective@#To understand the awareness and influencing factors of medical healthcare APP among female college students in Weifang, and to provide references for healthy lifestyle and health literacy improvement.@*Methods@#A total of 891 female college students were selected by stratified random sampling method, and were investigated regrading awareness on medical and health care APP and associated factors. Data were statistically analyzed by composition ratio, CHI-square test and binary Logistic regression.@*Results@#There were 54.6% of the female college students who reported not aware of medical healthcare APP. The overall awareness rates of medical and health care APP for freshmen,sophomores, juniors, seniurs and above were 39.75%,45.59%,55.78% and 52.56%, respectively, and the difference was statistically significant(χ2=16.43，P<0.05). Logistic regression analysis showed that medical costs, medical healthcare information attention, medical health care information recognition, consulting the treatment scheme were positively associated with awareness of health care APP(OR=1.40,1.51,1.27,1.33,P<0.05).@*Conclusion@#The awareness rate of medical health care APP of female college students in Weifang is relatively low,and the difference between different groups is obvious. It is necessary to improve the scientific knowledge rate of the female college students to the APP, so as to influence the life style of the female college students.
