[Purpose]To analyze the incidence and mortality of prostate cancer in Zhejiang cancer registration areas in 2021 and the trends from 2000 to 2021.[Methods]Data of prostate cancer incidence and mortality in Zhejiang cancer registration areas from 2000 to 2021 were collected.The crude incidence/mortality rates,age-standardized incidence/mortality rates by Chinese stan-dard population(ASIRC/ASMRC)and world standard population(ASIRW/ASMRW),cumulative rates(0～74 years old)were calculated.Joinpoint regression model was used to estimate the annual percentage change(APC)and average annual percentage change(AAPC)to assess trends.[Results]In 2021,6 683 new prostate cancer cases were reported in Zhejiang cancer registration areas,the crude incidence rate and ASIRC of prostate cancer were 61.21/105 and 26.78/105,respec-tively.The number of prostate cancer deaths was 1 036,the crude mortality rate and ASMRC were 9.49/105 and 3.28/105,respectively.From 2000 to 2021,a total of 30 876 new prostate cancer cases and 7 458 deaths were reported.The average crude incidence rate was 25.50/105,and the ASIRC was 13.35/105;the crude mortality rate and ASMRC rates were 6.16/105 and 2.82/105,respectively.The ASIRC was higher in urban areas(13.58/105)than that in rural areas(12.84/105),while the ASMRC was lower in urban areas(2.60/105)than that in rural areas(3.33/105).From 2000 to 2021,both the ASIRC and ASMRC showed significant upward trends in Zhejiang cancer registration areas with AAPC of 13.88％(95％CI:11.43％～16.08％,P＜0.001)and 4.35％(95％CI:2.21％～6.18％,P＜0.001),respectively.[Conclusion]Prostate cancer incidence in Zhejiang Province had risen rapidly in last two decades,with rural areas facing a heavier mortality burden.Special attention should be paid to the elderly male population in rural areas,and the three-level prevention strategy should be strengthened to reduce the disease burden.

Objective:To analyze the current status and trends of lung cancer incidence and mortality in China and selected global regions, providing evidence for lung cancer prevention strategies in China.Methods:We extracted data from the GLOBOCAN 2022 database. Age-standardized Incidence rate (ASIR) and Age-standardized Mortality rate (ASMR) were calculated using Segi's world standard population. Epidemiological patterns were analyzed by region, age, sex, and human development index (HDI). Simple linear regression and Spearman's rank correlation coefficient were used to examine associations between HDI and ASIR/ASMR.Results:In 2022, global lung cancer incidence and mortality reached 2.48 million and 1.82 million cases respectively, with age-standardized rates of 23.6 per 100 000 (ASIR) and 16.8 per 100 000 (ASMR). Gender disparities were prominent, with male ASIR and ASMR being 2.0-fold and 2.5-fold higher than females. Elderly populations showed 11.6-fold higher ASIR and 14.4-fold higher ASMR compared to working-age adults. HDI demonstrated strong positive correlations with both ASIR ( r=0.79, P＜0.001) and ASMR ( r=0.74, P＜0.001). China accounted for 1.06 million new cases and 0.73 million deaths, with ASIR (40.8 per 100 000) and ASMR (26.7 per 100 000) exceeding global averages by 1.7-fold and 1.6-fold respectively. Chinese males showed 1.7-fold higher ASIR and 2.7-fold higher ASMR than females. Trend analysis revealed persistently high male incidence in China whereas rapidly increasing female rates, narrowing gender disparities. Projections estimate 1.80 million incident cases and 1.41 million deaths by 2050, representing 69.3% and 92.0% increases from 2022 levels. Conclusions:Significant heterogeneity exists in lung cancer burden across demographics and development levels, with strong HDI correlations. China bears disproportionate disease burden, necessitating intensified prevention efforts. These findings underscore the urgency of targeted interventions in high-risk populations.

Polygonatum sibiricum polysaccharide(PSP)is a polysaccharide with multiple pharma-cological activities that has been widely studied and used in the human body.However,there is cur-rently a lack of research investigating the potential advantages of PSP in poultry farming.This study investigated the effects of adding PSP to drinking water on the growth performance,antioxi-dant status,serum biochemical indicators,ileal tissue morphology,immune organs,and intestinal function of chicks.88 Hailan brown laying hens were randomly divided into 4 groups,with 22 hens in each group,namely the blank control group(CON),and fed with basic feed;The low-dose PSP group(250 mg/L),the medium dose PSP group(500 mg/L),and the high-dose PSP group(1 000 mg/L)were fed with corresponding doses of PSP through drinking water on the basis of basic feed,and the experimental period was 21 d.The initial and final body weight and immune or-gan relative quality of chicks,serum biochemical indicators,the activities of SOD,CAT,and GSH-Px,as well as the contents of T-AOC and MDA in the serum of chicks were measured;HE stai-ning method was used to observe the pathological changes of intestinal tissue slices in the ileum;Real time fluorescence quantitative PCR technology was used to detect the mRNA expression lev-els of cytokines ZO-1,Claudin-1,Occludin,Mucin-2,IL-1β,TNF-a,IFN-γ,IL-4,IL-8,and IL-10 in the ileum.The results showed that compared with the blank control group,the addition of medium dose PSP significantly increased the final relative quality(P＜0.01),the final body weight and ADG of PSP500 group chicks significantly increased(P＜0.01),and the F/G of PSP250 and PSP500 groups significantly decreased(P＜0.05 or P＜0.01).The villus height of the jejunum in the 200,500,and 1 000 mg/L PSP groups of chicks significantly increased(P＜0.05).The SOD ac-tivity significantly increased(P＜0.01),and the CAT activity in the PSP1000 group significantly increased(P＜0.01).The PSP500 and PSP1000 groups significantly reduced the mRNA expression of cytokines IL-1β,IL-4,and IFN-γ in the ileum(P＞0.05);PSP did not show significant changes in serum total protein(TP),albumin(ALB),glucose(GLU),cholesterol(T-CHO)content,and immune organ index(P＜0.05).In summary,PSP can improve growth performance,enhance an-tioxidant capacity,improve ileal morphology and epithelial barrier function,and regulate mucosal immune status.Considering the overall economic benefits,the recommended level of PSP addition is 500 mg/L.

OBJECTIVE To explore the influence of surgical history on chemotherapy -induced nausea and vomiting （CINV）. METHODS A retrospective case -control study was adopted ，with 824 patients undergoing chemotherapy as the object . A total of 27 items were collected ，including demographic data ，medical history data ，pre-chemotherapy data ，and chemotherapy treatment status. Logistic regression model was used to analyze the relationship between the history of surgery and the risk of CINV . The multiple models were constructed to correct potential confounding factors ，and subgroup analysis was performed on patients with surgical history . RESULTS The incidence of CINV was higher in patients with surgical history . The statistical result before adjustment was [OR＝1.72，95%CI（1.31，2.28），P＜0.001]；after adjusting potential confounding factors ，the statistical result was [OR＝1.78，95% CI（1.28，2.48），P＝0.001]. In the subgroup analysis ，the time between surgery and chemotherapy was different ， and the impact of surgical history on CINV was different ，and the results were statistically significant （P＝0.027）. The risk of CINV showed decreasing trend with the time ，and the results were statistically significant （P for trend ≤0.050）. Compared with patients who had not undergone surgery ，patients who had undergone surgery within one year had a higher risk of CINV [OR＝ 2.33，95%CI（1.52，3.59），P＜0.001]. CONCLUSIONS Patients with surgical history are more prone to CINV ，and the risk of CINV shows a downward trend in the length of time from surgery .

Objective:To analyze the status of secondary maternal and child health hospital accreditation in China and the impact of such accreditation on their service improvement.Methods:The paper used the propensity score matching method to match the accreditation group and the non-accreditation group in 1∶1 ratio, and compared the related indicators of service capability of maternal and child health hospitals between the two groups by non-parametric test and Chi-square test.Results:A total of 842 maternal and child health care hospitals were matched. A comparison was made between the accreditation group and the non-accreditation group, and the differences of the following indicators of individual services within the hospital were statistically significant( P<0.01). These indicators were annual emergency attendance, the number of types of health services for women and children, the utilization rate of beds, the average daily hospital bed of each practicing physician; the following indicators of service management within their coverage were statistically significant: namely the proportion of institutions carrying out health education evaluation within their coverage, that of institutions producing uniform " Mother and Child Health Handbook", that of institutions carrying out information quality control, as well as analysis and utilization.These indicators of the accreditation group were higher than those in the non-accreditation group( P<0.01). Conclusions:Given the role played by maternal and child health institution accreditation in promoting secondary maternal and child health hospital regarding better service content, quantity, efficiency and the quality of business management within their coverage, there is still room for improvement.

The HIV-infected people were investigated for their satisfactory situation towards the follow-up management of primary medical and health care institutions in Xinjian County, Yushan County and Guixi City of Jiangxi Province from January to July 2018 and related factors were also analyzed. The total score of the Infected Patients′ Follow-up Management Satisfaction Scale higher than 59 was defined as the satisfactory. 75.68% of 259 infected patients were satisfied with the follow-up management. Compared to farmers and other follow-up modes, non-farmers (OR=10.72, 95%CI: 2.07-55.63), and patients receiving follow-up service in responsible institutions (OR=6.44, 95%CI: 3.12-13.30) were more satisfied with follow-up management.
