ABSTRACT
Objective@#To understand the changes of children s height, weight, blood pressure and gender differences, to explore the relationship between overweight, obesity and childhood hypertension, and to provide a scientific basis for childhood hypertension prevention.@*Methods@#Physical examination data during 2013 to 2018 of ten primary school students in Shenzhen were collected. Growth rate of height, weight and blood pressure by age and gender were calculated. The generalized estimating equation was used to analyze the association between overweight, obesity and hypertension.@*Results@#Weight, body mass index (BMI) and systolic pressure of boys and girls increased with age ( t/Z =3.89-31.52, P <0.05). The height growth rate of girls was higher than that of boys at the age of 8-11, and reaches the peak of height growth at the age of 10, while boys were two years later than girls(boys:7.68 cm, gilrs:7.42 cm). Weight and blood pressure growth rates were similar. At the same time, the growth rate of height and blood pressure had a synchronous trend, and the peak of the growth rate of blood pressure was also at the peak stage of height growth. The OR value of obesity on childhood hypertension was 1.62(1.48-1.81), and the OR value of overweight on childhood hypertension was 2.01(1.75-2.30), both P <0.01.@*Conclusion@#There are gender differences in children s height, weight, and blood pressure, and the growth rate of height and blood pressure shows a synchronous trend. Overweight and obesity in children can increase the risk of high blood pressure and hypertension.
ABSTRACT
Objective:To analyze the incidence and death characteristics of cancer and survival rate of residents in Qingpu District， Shanghai from 2012 to 2016， and to provide a scientific basis for subsequent cancer prevention and treatment. Methods:The malignant tumor incidence and death data were collected by the Shanghai Malignant Tumor Case Registration System. Based on these data， the crude incidence and mortality rate of cancer， the standardized rate， the order of incidence and death of the top 10 cancers， and the overall survival rate were calculated using the life table method. The relative survival rate for 1 to 5 years was calculated using the Ederer II method according to survival probability in the abbreviated life table for the same period. The annual percentage change （APC） was calculated by Joinpoint software， and the trend of morbidity and mortality was analyzed. Results:A total of 10 893 new malignant tumor cases were diagnosed in the region from 2012 to 2016. The crude incidence rate of cancer in the whole region was 464.68/100 000 （502.06/100 000 for men and 428.57/100 000 for women）， and the standardized incidence rate was 224.61/100 000 （235.52/100 000 for men， and 217.98/100 000 for women）. A total of 5 820 people died of cancer， the crude mortality rate of cancer in the whole region was 248.28/100 000 （321.92/100 000 for men and 177.13/100 000 for women）， and the standardized mortality rate was 97.08/100 000 （133.14/100 000 for men and 66.38/100 000 for women）. Patients with malignant tumors diagnosed in Qingpu District in 2012 showed higher 5-year relative survival for breast cancer （87.03%）， malignant tumors of brain and central nervous system （73.62%）， and colorectal cancer （58.22%）. A relative low 5-year survival rate was observed in patients with pancreatic cancer （3.76%）， esophageal cancer （10.55%）， and liver cancer （15.79）. Conclusion:Lung cancer and malignant tumors of the digestive system （including gastric cancer and colorectal cancer） are the main types of cancer threatening the health of residents in Qingpu District. The survival rates of breast cancer， malignant tumors of brain and central nervous system， and colorectal cancer have reached or approached the level of developed countries. However， the overall survival rate of malignant tumors in Qingpu District is lower than that in the city， and needs to be further improved.
ABSTRACT
Objective Serum total prostatic specific antigen (tPSA), free prostatic specific antigen (fPSA), fPSA/tPSA ratio, and prostate cancer-specific antigen density (PSAD) were determined to explore the best identification point, thus improving the specificity of early screening of prostate cancer. Methods The tPSA, fPSA, fPSA/tPSA, and PSAD of patients with benign prostatic hyperplasia group (n=250) and prostate cancer group (n=92) were tested, and the receiver operating characteristic (ROC) curve was drawn to determine the best cutoff value for the evaluation. Results When the cutoff values of tPSA, fPSA/tPSA, and PSAD were at 11.3 mg/L, 0.16, and 0.18 mg/(L·cm3), respectively, the specificity and sensitivity were the best:82.4% and 84.2% for tPSA, 76.9% and 81.7% for fPSA/tPSA, and 83.1% and 80.4% for PSAD.When the best cutoff values of tPSA, fPSA/tPSA, and PSAD were combined in analysis, the specificity and sensitivity of fPSA/tPSA and PSAD combination showed the best result (92.4% and 81.4%, respectively).When the tPSA value was in the range of 4-10 mg/L, the optimal cutoff values of PSAD and fPSA/tPSA were 0.21 mg/(L·cm3) and 0.15, and the specificity and sensitivity reach the best, which were 84.1% and 80.1%, 81.0 % and 80.3%, respectively. Conclusion Combination of tPSA, fPSA/tPSA and PSAD analysis is better than any single of them in early screening of prostate cancer.The specificity and sensitivity of combined use of fPSA/tPSA and PSAD could serve as an optimal screening reference value.
