[Purpose]To analyze the incidence and mortality of gastric cancer in Zhejiang cancer registration areas in 2021,and trends from 2000 to 2021.[Methods]The data of gastric cancer were obtained from Zhejiang cancer registration areas.The crude incidence/mortality rates,age-specific rates,and age-standardized incidence/mortality rates by Chinese standard population(ASRC)and the world standard population(ASRW)were calculated.The temporal trends were ana-lyzed by calculating annual percentage change(APC)and average annual percentage change(AAPC).[Results]A total of 7 602 new cases and 4 178 deaths of gastric cancer were reported in 2021.The incidence and mortality rates of gastric cancer in men were significantly higher than those in women;the incidence rate in urban areas was significantly higher than that in rural areas,while the mortality was slightly lower than that in rural areas.From 2000 to 2021,the ASRC of inci-dence rate decreased from 16.80/105 to 16.08/105(without statistical significance):an upward trend was observed from 2000 to 2009,whereas a downward trend became apparent from 2009 to 2021.From 2000 to 2021 the ASRC of mortality rate decreased from 13.59/105 to 8.02/105 with an AAPC of-2.62％(P＜0.001).The decline rate of female mortality rate(AAPC=-2.68％,95％CI:-3.61％～-1.68％,P＜0.001)was slightly higher than that of male(AAPC=-2.44％,95％CI:-3.06％～-1.61％,P＜0.001).[Conclusion]In 2021,both the incidence and mortality rates of gastric can-cer in Zhejiang Province were lower than the national average in China,which ranked 6th and 4th among all types of cancer.From 2000 to 2021,the overall burden of gastric cancer in Zhejiang Province showed a downward trend.

Objective:To explore the clinical significance of interleukin 6(IL 6) in pathogenesis of diabetic nephropathy by comparing the plasma and urinary level of IL 6 in patients with type 2 diabetes mellitus(DM).Methods:The plasma and urinary level of IL 6 were measured with radioimmunoassay in 20 normal controls(NC group) and 45 cases of type 2 DM,including 23 cases without albuminuria(DSM group) and 22 cases with trace albuminuria(EDN group).Results:(1)The plasms and urinary level of IL 6 markly elevated in SDM group(P
