Objective:To analyze the screening results of the Urban Cancer Early Diagnosis and Treatment Project in Qinghai Province from 2019 to 2024.Methods:A summary and statistical analysis were conducted on six years of screening data from the Urban Cancer Early Dia-gnosis and Treatment Program in Qinghai Province,with the high-risk rate,screening rate,and detection rate calculated separately for each type of cancer.Results:From 2019 to 2024,56,882 high-risk individuals were identified.The high-risk rates for lung,colorectal,breast,up-per gastrointestinal,and liver cancer were 22.02%,21.57%,14.23%,13.52%,and 6.10%,respectively.Overall,13,592 individuals com-pleted clinical screening,with detection rates of 0.32%for lung cancer,0.41%for liver cancer,0.08%for precancerous gastric lesions,3.63%for precancerous colorectal lesions,0.08%for esophageal cancer,0.16%for gastric cancer,and 0.14%for colorectal cancer.Conclusions:The implementation of the Urban Cancer Early Diagnosis and Treatment Program in Qinghai Province aids in the early detection of cancer,improves early diagnosis and survival rates,and reduces mortality.Nevertheless,due to low public awareness and limited participation,en-hancements in program management and public outreach are required.

Objective To investigate the expression of apolipoprotein M in rats after renal transplantation and its role and action mechanism in acute rejection (AR).Methods The kidney transplantation model in rats were established.Male SD and Wistar rats were used as donors,and Wistar rats as recipients.Three groups were designated:control group (syngeneic transplantation,n =24,recipients were treated with normal saline i.p.); AR group (allogeneic transplantation,n =24,recipients were treated with normal saline i.p.); PDTC group [allogeneic transplantation,n =24,recipients were treated with NF-κB inhibitor-pyrrolidine dithiocarbamat (PDTC) i.p.].The renal grafts were drawn at day 1,3,5 and 7 post-transplantation,and the expression levels of NF-κB P65 and apoM protein were detected by using Western blotting,and those of apoM,perforin and granzyme B mRNA were by using real-time PCR.The correlation of apoM and NF-κB,apoM and perforin,and apoM and granzyme B was respectively analyzed.Results As compared with control group,the expression levels of apoM,perforin and granzyme B mRNA in AR and PDTC groups were dramatically up-regulated at each time point (P＜0.01),and those in PDTC group were significantly lower than those in AR group (P＜0.01).The expression levels of apoM and NF-κB protein in AR group were both distinctly higher than those in control group (P＜0.01),and those in PDTC group were markedly lower than those in AR group (P＜0.01).A significantly positive correlation was found between the expression of apoM and NF-κB protein (r =0.469,P＜0.05).And the expression of apoM mRNA was positively correlated to perforin and granzyme B mRNA (r =0.731,P＜0.01 ; r =0.514,P＜0.05).Conclusion The expression of apoM is obviously up-regulated in renal grafts of rats,which may take part in the pathogenesis of AR via NF-κB.
