Epidemiology of gynecologic cancers in China
Xiyi Jiang,Huijuan Tang,Tianhui Chen 대한부인종양학회 2018 Journal of Gynecologic Oncology Vol.29 No.1
Cancer has become a major disease burden across the globe. It was estimated that 4.29 million new incident cases and 2.81 million death cases of cancer would occur in 2015 in China, with the age-standardized incidence rate (ASIR) of 201.1 per 100,000 and age-standardized mortality rate (ASMR) of 126.9 per 100,000, respectively. For females, 2 of the top 10 most common types of cancer would be gynecologic cancers, with breast cancer being the most prevalent (268.6 thousand new incident cases) and cervical cancer being the 7th most common cancer (98.9 thousand new incident cases). The incidence and mortality of gynecologic cancers have been constantly increasing in China over last 2 decades, which become a major health concern for women. Survival rates of gynecologic cancers are generally not satisfactory and decrease along with advancing stage, though national data on survival are still not available. It is of great importance to overview on the epidemiology of gynecologic cancers, which may provide scientific clues for strategy-making of prevention and control, and eventually lowering the incidence and mortality rate as well as improving the survival rate in the future.

A modified SiO2 material (MSM) was successfully synthesized by using Na2SiO3 and a novel CO2SM in the presence of CTAB through an innovative hydrothermal releasing treatment protocol. The MSM was systemically characterized using several techniques, including N2 adsorption-desorption isotherm, thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The CO2SM as a platform for CO2 capturing and releasing can be reversibly used for multiple cycles without significant loss of capabilities. The optimum conditions for the preparation of MSM were identified as follows: Na2SiO3 concentration, 0.2mol/L; hydrothermal temperature, 120 oC; CO2SM dosage, 6 g; CTAB concentration, 24 g/L, reaction time, 12 h. Additionally, the MSM exhibited high efficiency for the removal of phenol from aqueous solution: it showed a phenol adsorption capacity of 91.29mg/g when shaken with the aqueous phenol solution at 180 rpm for 1 h at 25 oC.
