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.

OBJECTIVES: To explore the efficacy of DSA-guided intrathecal drug delivery system combined with Zi Wu Liu Zhu Acupoint Therapy for management of cancer pain and provide reference for its standardized clinical application. Methods and. RESULTS: Recommendations were formulated based on literature review and expert group discussion, and consensus was reached following expert consultation. The consensus recommendations are comprehensive, covering the entire treatment procedures from preoperative assessment and preparation, surgical operation process, postoperative management and traditional Chinese medicine treatment to individualized treatment planning. The study results showed that the treatment plans combining traditional Chinese with Western medicine effectively alleviated cancer pain, reduced the use of opioid drugs, and significantly improved the quality of life and enhanced immune function of the patients. Postoperative follow-up suggested good treatment tolerance among the patients without serious complications. CONCLUSIONS The formulated consensus is comprehensive and can provide reference for clinicians to use DSA-guided intrathecal drug delivery system combined with Zi Wu Liu Zhu Acupoint Therapy. The combined treatment has a high clinical value with a good safety profile for management of cancer pain.

Objective:To investigate the microRNA (miRNA) expression features in ectopic endometrial tissues of endometriosis (EMS) patients.Methods:From April 2018 to October 2019, ectopic endometrial tissues from EMS patients and eutopic endometrial tissues from control women who received treatment in the Department of Obstetrics and Gynecology of The First Affiliated Hospital of Xiamen University were used in subsequent experiments. Differentially expressed miRNAs were screened out in ectopic endometrial tissues by detecting miRNA sequence from Illumina. The potential roles of these differentially expressed miRNAs and their potential targeted genes in pathogenesis of EMS were analyzed by bioinformatics, and the differential expression levels of 6 miRNAs (miR-98-5p, miR-495-3p, let-7c-5p, miR-200b-3p, miR-200c-3p, miR-148b-3p) were validated by quantitative real-time polymerase chain reaction (qRT-PCR) and subsequently used to build the miRNA-gene regulatory network, then we verified its potential target gene.Results:The microarray results showed that 69 miRNAs might be differentially expressed in ectopic endometrial tissues compared with those in eutopic endometrial tissues (fold change>1.5, P<0.05), including 22 up-regulated miRNAs and 47 down-regulated miRNAs. Gene ontology (GO) analysis showed that the target genes of these differentially expressed miRNAs mainly participated in the protein modification, regulation of development, cell metabolism and morphological structure. KEGG pathway analysis showed that these targeted genes were involved in protein function, autophagy, AGE-RAGE and MAPK signaling pathways. The expression levels of miR-98-5p, let-7c-5p, miR-200b-3p and miR-200c-3p were validated to be significantly altered in ectopic endometrial tissues. The miRNA-gene co-expression network revealed the correlation between the 4 miRNAs and their predicted target genes. qRT-PCR validated results showed that the expression of miR-200b-3p and miR-200c-3p were significantly negatively correlated with ZEB2, while miR-98-5p was negatively correlated with PGRMC1, miR-98-5p and let-7c-5p were positively correlated with ADIPOR2. Conclusion:MiR-98-5p, let-7c-5p, miR-200b-3p and miR-200c-3p were significantly differentially expressed in the ectopic endometrial tissues of EMS patients, which may be involved in the development of EMS.

The phenomenon of phase separation of intracellular biological macromolecules is an emerging research field that has received great attention in recent years. As an aggregation and compartment mechanism of cell biochemical reactions, it widely exists in nature and participates in important physiological processes such as gene transcription and regulation, as well as influences organism's response to external stimuli. Disequilibrium of phase separation may lead to the occurrence of some major diseases. Researchers in cross-cutting fields are trying to examine dementia and other related diseases from a new perspective of phase separation, exploring its molecular mechanism and the potential possibility of intervention and treatment. This review intends to introduce the latest research progress in this field, summarize the major research directions, biochemical basis, its relationship with disease occurrence, and giving a future perspective of key problems to focus on.
