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: In order to provide a scientific basis for the quality control of Kunxian Capsules (KC), HPLC characteristics chromatogram combined with multi-components determination was established. Methods: The analysis was performed on Agilent Zorbax SB-C18 column (250 mm × 4.6 mm, 5 μm), using acetonitrile and 0.1% phosphoric acid solution as the mobile phase at a flow rate of 0.8 mL/min for gradient elution, the column temperature was 33 ℃, and the detection wavelength was 270 nm. The fingerprints of 15 batches of KC were established and evaluated by the similarity evaluation system of TCM (2012A version), hierarchical cluster analysis and discriminant analysis of partial least squares. Furthermore, the content of hyperoside, epimedin A, epimedin B, epimedin C, icariin and baohuoside Ⅰ were determined. Results: The HPLC fingerprint with 21 common peaks of KC was established, and the similarities of samples were over 0.9. The linearity relationships separated with hyperoside, epimedin A, epimedin B, epimedin C, icariin and baohuoside Ⅰ were good, and the contents of the above-mentioned components in 15 batches of preparations were 2.817-7.527, 7.287-9.103, 8.730-18.675, 33.377-70.371, 35.297-50.291 and 4.059-9.079 mg/g, respectively. Conclusion: The combination methods of HPLC characteristic chromatograms and simultaneous determinations of multiple components are rapid, simple and reproducible, which can provide methodological reference for the quality control of KC.
