[Purpose]To analyze the trend of non-Hodgkin's lymphoma incidence in Qidong City of Jiangsu Province from 1972 to 2021.[Methods]The data of non-Hodgkin's lymphoma inci-dence collected from Qidong Cancer Registry from 1972 to 2021 were extracted.The crude inci-dence rate(CR),age-standardized rate by Chinese standard population(ASRC)and by world standard population(ASRW),truncated incidence rate(35～64 years old)and cumulative incidence rate(0～74 years old)were calculated.The age-period-cohort model was used to analyze the age,period,and cohort effects of incidence in non-Hodgkin's lymphoma.Joinpoint 4.9.1.0 software was used to calculate the average annual percentage change(AAPC)of non-Hodgkin's lymphoma incidence for trend analysis.[Results]There were a total of 2 681 cases of non-Hodgkin's lymphoma re-ported in Qidong from 1972 to 2021.The CR,ASRC,ASRW,the truncated incidence(35～64 years old)rate and cumulative incidence rate(0～74 years old)were 4.78/105,3.35/105,3.30/105,5.20/105 and 0.37％,respectively.There were 1 589 male cases,with CR,ASRC and ASRW of 5.75/105,4.19/105 and 4.14/105,respectively;and there were 1 092 female cases,with CR,AS-RC and ASRW of 3.84/105,2.60/105 and 2.54/105,respectively.Age-period-cohort analysis showed that the net drift value of non-Hodgkin's lymphoma incidence was 1.65(95％CI:1.19～2.11),and age,period and cohort effects were all important influencing factors of non-Hodgkin's lymphoma incidence rate(all P＜0.05).The AAPCs for both sex,male and female of ASRC of non-Hodgkin's lymphoma in Qidong from 1972 to 2021 were 1.71％(95％CI:0.88％～2.54％,t=4.07),1.62％(95％CI:1.14％～2.11％,t=6.77),and 2.01％(95％CI:0.77％～3.26％,t=3.19),respectively,with a significant upward trend,and the differences were statistically significant(all P＜0.01).[Conclusion]Non-Hodgkin's lymphoma in Qidong City shows an overall increasing trend in the age-standardized incidence over the past 50 years,with a higher incidence in male and in the el-derly population.

[Purpose]To analyze the trend of incidence rates of gallbladder cancer in Qidong City of Jiangsu Province from 1972 to 2021.[Methods]The incidence data of gallbladder cancer from 1972 to 2021 were collected from the Qidong Tumour Registry database,the crude incidence rate(CR),age-standardized rate by Chinese standard population(ASRC),age-standardized rate by world standard population(ASRW)of gallbladder cancer were calculated.Trend analysis was per-formed using Joinpoint 4.9.1.0 software to calculate the average annual percentage change(AAPC)of gallbladder cancer incidence rates,and time trend analysis was performed on the overall inci-dence rate by sex and age.[Results]A total of 1 369 cases of gallbladder cancer occurred in Qi-dong City from 1972 to 2021,accounting for 0.93％of all malignant tumors.The overall CR of gallbladder cancer was 2.44/105 in 50 years,ASRC was 0.88/105 and ASRW was 1.45/105.The truncated rate of 35～64 years old was 1.98/105,the cumulative incidence of gallbladder cancer at 0～74 years old was 0.16％,and the risk of cumulative incidence of gallbladder cancer was 0.16％.CR was slightly higher in women than that in men,but after standardization it was slightly higher in men than that in women.The sex ratio of CR,ASRC and ASRW was 0.89,1.07 and 1.06,respectively.With the increase of age,the incidence of gallbladder cancer was also increased.The age of onset was slightly increased in last 50 years.In last 50 years,there was an upward trend in the overall incidence of gallbladder cancer,the incidence both for men and women,and the inci-dence of each age group.[Conclusion]The incidence of gallbladder cancer in Qidong City has increased considerably during the past 50 years,and continuing attention should be paid to the prevention and treatment of gallbladder cancer especially for the key populations.

[Purpose]To analyze the survival rate of breast cancer in Qidong City of Jiangsu Province from 1972 to 2019 and to predict the trend in the next 10 years.[Methods]The data of breast cancer collected from Qidong Cancer Registry from 1972 to 2019 were extracted.Observed survival rate(OSR),relative survival rate(RSR),age-adjusted relative survival(ARS)and average annual percentage change(AAPC)of breast cancer were calculated.ARIMA model was used to predict the trend of breast cancer survival rate.[Results]The 5-year RSR increased from 57.30％during 1972-1977 to 89.01％during 2014-2019,and the uptrend of RSR in the 8 periods was statistically significant(P＜0.001).The 5-year ARS increased from 48.12％during 1972-1977 to 85.64％during 2014-2019 with an AAPC of 1.85％(t=10.113,P＜0.001).The 5-year RSR during 1972-2019 for males was 85.22％,and for females was 74.51％.For females,the 5-year RSR in-creased from 56.44％during 1972-1977 to 88.93％during 2014-2019 with an AAPC of 1.29％(t=13.087,P＜0.001),and the 5-year ARS increased from 46.14％during 1972-1977 to 85.23％during 2014-2019 with an AAPC of 1.90％(t=10.369,P＜0.001).The 5-year RSR in the age groups of 25～34,35～44,45～54,55～64,65～74,and over 75 years old were 66.91％,74.69％,76.97％,75.52％,73.44％and 66.40％,respectively;the corresponding AAPCs of 5-RSR in above age groups were 1.02％(t=3.816,P=0.009),1.03％(t=4.936,P=0.003),1.23％(t=5.826,P=0.001),1.86％(t=5.997,P=0.001),2.13％(t=10.245,P＜0.001),and 1.44％(t=6.405,P=0.001),respectively.ARIMA modeling of survival trend prediction showed that 5-RSR and 5-ARS for breast cancer will be ascended to 98.76％and 98.33％by 2028,respectively.[Conclusion]The overall survival rate of registered breast cancer cases in Qidong City has been greatly improved and will be further improved in the future,more attention should be paid to the prevention and treatment of breast cancer.

Raynaud syndrome is a clinical syndrome characterized by paroxysmal vasospasms of the acral small arteries,and its pathogenesis is closely associated with the dynamic imbalance of yin and yang as elucidated by the theory of"yang transforming qi and yin shaping up body."The theory of"yang transforming qi and yin shaping up body"originated in Huangdi Neijing,which is aimed at that yang can be tangible essence,blood,fluid,and other substances belonging to the yin into an invisible qi,promote the internal and external zang-fu organs and qi of the body's operation;yin qi is transformed into tangible substances under the gasification effect of yang qi to nourish the organism,to consolidate the essence of internal zang-fu organs,and to maintain the balance of yin and yang in the body.This study innovatively employs this theory to systematically elucidate the dynamic pathomechanism evolution of Raynaud syndrome:at the beginning of the disease,the ischemic stage is dominated by the deficiency of yang qi and the inability of qi to transform yin;then the disease enters into the hypoxic stage and the dilatation stage,which are mostly caused by the lack of yang depression,the blockage of qi,and the over-excessive formation of yin;and finally,the yang transforms qi too much and yin is damaged and weak,and then reaches the stage of complication.In Raynaud syndrome,the key mechanism and pathology of"yang transforming qi"and"yin shaping up body"as well as the stage of the disease should be clarified,so that yang qi can be used as the basis to make up for yang deficiency,yang depression can be stretched out,yin evils such as cold condensation,blood stasis and water dampness can be transformed,heat and toxin can be eliminated,yin fluids can be restored,and the extremities can be warmed up.The disease will be convalesced gradually.

Objective:To describe and analyze the incidence, mortality and epidemiological trends of liver cancer in China and selected regions worldwide, providing data references for liver cancer prevention and control.Methods:Data on the incidence, mortality, historical trends, and projected estimates for 2050 of liver cancer were extracted from the GLOBOCAN 2022 database. Epidemiological characteristics of liver cancer in China and other region were described and compared by region, age, sex and human development index (HDI). Spearman's test was used to examine the relationships between HDI and age-standardized incidence rate (ASIR) or age-standardized mortality rate (ASMR) across regions. The average annual percentage change (AAPC) in ASIR was calculated using Joinpoint regression analysis.Results:In 2022, the number of new cases and deaths of liver cancer in the global were 866 000 and 759 000 respectively, and the ASIR and ASMR were 8.6/10 5 and 7.4/10 5, respectively. Both ASIR and ASMR were higher in males than in females. In China, there were 368 000 new cases and 317 000 deaths in 2022, with an ASIR of 15.0/10 5 and an ASMR of 12.6/10 5. Globally, the incidence of liver cancer in males peaked in the 65-69 age group, while in Chinese males, two incidence peaks were observed in the 50-54 and 65-69 age groups. Among the elderly (≥65 years), the global ASIR and ASMR were 7.4 and 8.1 times higher, respectively, than those in the working-age population (15-64 years). In China, the ratios of ASIR and ASMR between the elderly and working-age populations were 5.9 and 7.0, respectively. Both ASIR and ASMR were negatively correlated with HDI (ASIR: r=-0.18, P=0.018; ASMR: r=-0.31, P＜0.001). From 2002 to 2017, ASIR of liver cancer showed a declining trend in both males and females in China, Japan, and South Korea (all P＜0.001), with AAPCs of -1.96% for Chinese males and -2.75% for Chinese females. In contrast, the United States experienced an increasing trend in ASIR, with AAPCs of 3.13% for males and 3.12% for females (both P＜0.001). Projections indicate that by 2050, the number of new cases and deaths globally will reach 1.564 million and 1.421 million, representing increases of 80.6% and 87.2% compared to 2022, respectively. In China, the number of new cases and deaths are projected to be 560 000 and 514 000, increases of 52.2% and 62.1% from 2022, respectively. Conclusions:The burden of liver cancer varies significantly across regions, sexes, and age groups worldwide. Incidence and mortality rates are negatively correlated with HDI. The global burden of liver cancer is expected to continue increasing, underscoring the need for enhanced comprehensive prevention and control strategies.

Objective:To describe the epidemiological characteristics and trends of lung cancer incidence in Qidong City, Jiangsu Province, China, between 1972 and 2021, and provide guidelines for prevention and control.Methods:Data on lung cancer with onset from January 1, 1972 to December 31, 2021 and coded as C33-C34 in the International Classification of Diseases (10th edition) were extracted from the tumor registry database of Qidong City. Population data of Qidong City for each year from 1972 to 2021 were extracted from the annual report of household registration of the Public Security Bureau of Qidong City. The crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), 35-64 years truncated rate, 0-74 years cumulative rate, and cumulative risk were calculated. Average annual percentage change (AAPC) was calculated by Joinpoint software for CR, ASRC, and ASRW. The age-period-cohort (APC) model was used to analyze the influence of age, period, and birth cohort on the changes in the incidence trend of lung cancer.Results:From 1972 to 2021, there were 26 996 patients of lung cancer in Qidong, accounting for 18.30% (26 996/147 519) of all cancer new cases. The CR of lung cancer was 48.13/10 5, the ASRC was 29.65/10 5, and the ASRW was 29.67/10 5. The truncated incidence of 35-64 years old was 42.64/10 5, the cumulative incidence rate between the ages between 0-74 years old was 3.71%, and the cumulative risk was 3.64%. There were 18 572 male patients, with the CR, ASRC, and ASRW being 67.15/10 5, 43.82/10 5, and 43.87/10 5, respectively. The number of female patients was 8 424, and the CR, ASRC, and the ASRW were 29.62/10 5, 17.63/10 5, and 17.55/10 5, respectively. Temporal analysis indicated significant upward trends in the ASRCs for both genders combined, males, and females, with AAPC values of 2.21%, 1.76%, and 2.98% (all P<0.001), respectively. Age-specific incidence rates increased with age, peaking at 275.34/10 5 in the 75+ years age group, with an increasing trend in all age groups and the greatest increase in the 75+ years age group, with an AAPC value of 3.53% ( P<0.001). The results of the APC model showed that the net drift value of lung cancer incidence was 2.06% (95% CI: 1.72%-2.41%), and the highest value of local drift was 3.93% (95% CI: 3.20%-4.68%) in the 80+ years old group. The risk of cancer increases with age in the age effect. The period effect of the incidence rate ratio (RR) value increased from 1.12 during 1997-2001 to 2.09 during 2017-2021. The cohort effect of the RR value for risk of incidence increased from 0.17 during 1892-1896 to 2.54 during 1987-1991. Conclusions:From 1972 to 2021, the incidence rate of lung cancer in Qidong City showed an upward trend. Age, period, and cohort are all major factors influencing the incidence of lung cancer. It is necessary to develop precise and comprehensive prevention and control strategies to curb this increasing trend of lung cancer incidence.

[Purpose]To analyze global epidemic status of colorectal cancer and explore the rela-tionship between the human development index(HDI)and the burden of colorectal cancer.[Methods]Based on the GLOBOCAN 2022 estimation data,the disease burden of colorectal can-cer in different regions,countries,and levels of HDI were analyzed.Spearman's rank test was used to explore the correlation between HDI and colorectal cancer disease burden.[Results]The estimated global incidence of colorectal cancer in 2022 was 1 926 425 cases(1 069 446 for male and 856 979 for female),with a age-standardized incidence rate of 18.4/105(21.9/105 for male and 15.2/105 for female),and cumulative risk of incidence of 2.10％(2.60％for male and 1.70％for female);the estimated number of deaths was 904 019(499 775 for male and 404 244 for fe-male),with a age-standardized mortality rate of 8.1/105(9.9/105 for male and 6.5/105 for female)and cumulative risk of death of 0.84％(1.00％for male and 0.65％for female).1-crude mortality rate/crude incidence rate(1-M/I)was 0.53(0.53 for male and 0.53 for female).Large disparities were in the disease burden of colorectal cancer between different regions and countries.After grouped by HDI,we found that the age-standardized incidence rates in very high,high,median,and low HDI regions were 28.6/105,18.1/105,6.7/105,and 6.4/105,and the standardized mortality rates were 10.5/105,8.3/105,3.9/105,and 4.5/105,with 1-M/I of 0.57,0.52,0.43 and 0.30,respec-tively;and the incidence and mortality rates were increasing with age.Spearman's correlation analysis showed a strong positive correlation between HDI and colorectal cancer in age-standardized incidence(r=0.84),age-standardized mortality(r=0.71)and 1-M/I(r=0.82)(all P＜0.001).[Con-clusion]The global burden of colorectal cancer remains high.There are disparities in the disease burden among countries and regions,which is positively correlated with their HDI levels,indicating that the colorectal cancer prevention and treatment strategies should be developed based on the conditions of each regions and countries accordingly.

Objective:To analyze pancreatic cancer incidence and mortality data in China and worldwide and to provide data for pancreatic cancer prevention and control efforts.Methods:Data of pancreatic cancer incidence and mortality rates, along with historical and predictive data, were obtained from the GLOBOCAN 2022 database. Epidemiological characteristics of pancreatic cancer was analyzed by region, sex, age and Human Development Index (HDI). Spearman's correlation coefficient test was used to assess the relationship between HDI and age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR).Results:In 2022, the global number of new cases and deaths of pancreatic cancer will be 511 thousand and 467 thousand, respectively, with an ASIR and ASMR of 4.7/10 5 and 4.2/10 5, respectively. North America and Europe had the highest pancreatic cancer incidence and mortality rates of 8.5/10 5 and 7.3/10 5, respectively. Global ASIR and ASMR in men were both 1.4 times higher than those in women. HDI levels were positively correlated with ASIR ( r=0.79, P＜0.001) and ASMR ( r=0.78, P＜0.001) of pancreatic cancer in all regions. The number of pancreatic cancer cases and deaths in China were 119 thousand and 106 thousand, respectively, while the ASIR and ASMR of pancreatic cancer were 4.4/10 5 and 3.9/10 5, respectively. Both ASIR and ASMR in men were both 1.5 times higher than those in women in China. The number of pancreatic cancer incidence and death cases in China in 2050 is predicted to be 216 thousand and 204 thousand cases, with an increase of 81.5% and 92.5% compared with 2022, respectively. Conclusions:The disease burden of pancreatic cancer varies significantly among different regions, genders and ages. Pancreatic cancer incidence and mortality are positively correlated with HDI. The incidence and mortality rates of pancreatic cancer in China are close to the global average, but the number of new cases and deaths is high. Prevention and control should be strengthened to improve the survival of pancreatic cancer patients.

Objective:To describe the epidemiological characteristics of breast cancer incidence in Qidong City between 1972 and 2021, and provide guidelines for preventive and control measures and strategies.Methods:The cancer registry data were collected and breast cancer incidences during 1972 and 2021 in Qidong by sex, age, and time were analyzed. Crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), annual percentage change (APC), and average annual percentage change (AAPC) were calculated by Joinpoint software. The age-period-cohort model was used to analyze the influence of age, period, and birth cohort on the changes in the incidence trend of breast cancer.Results:From 1972 to 2021, there were 6 929 patients with breast cancer in Qidong, accounting for 4.70% of all new cancer cases, with a CR of 12.35/10 5, a ASRC of 6.63/10 5, and a ASRW of 8.89/10 5. The truncated incidence rate among people aged 35-64 years was 21.90/10 5. The cumulative incidence rate of the ages between 0 and 74 years was 0.96%. The cumulative risk was 0.96%. There were 98 male patients, whose CR, ASRC, and ASRW were 0.35/10 5, 0.17/10 5, and 0.25/10 5, respectively. The number of female patients was 6 831, and the CR, ASRC, and ASRW were 24.02/10 5, 12.86/10 5, and 17.13/10 5, respectively. The AAPC of ASRW of female breast cancer was 3.45% (95% CI: 2.90%-4.01%). The increasing trend of the incidence rate was statistically significant ( P＜0.05). The AAPCs of females aged 25-34, 35-44, 45-54, 55-64, 65-74, and ≥75 years were 2.78% (95% CI: 0.88%-4.72%), 2.20% (95% CI: 0.83%-3.60%), 3.81% (95% CI: 2.45%-5.19%), 4.48% (95% CI: 3.12%-5.85%), 3.79% (95% CI: 2.19%-5.43%), and 2.87% (95% CI: 1.14%-4.63%). The increasing trends of the incidence rates in all age groups were statistically significant ( P＜0.05). The age-period-cohort model showed that the risk of breast cancer increased with age, and people born later were faced with a higher risk of the disease ( P＜0.05). Conclusion:The incidence of breast cancer presented a rising trend in the past fifty years in Qidong. The increasing trend of the incidence rate was statistically significant since the beginning of this century. The health administrative department should formulate preventive and control measures to reduce the burden of breast cancer.
