In 2025, the American Cancer Society published "Cancer statistics, 2025", which projected cancer data for the upcoming year based on incidence data collected by central cancer registries (through 2021) and mortality data obtained from the National Center for Health Statistics (through 2022). Similarly, the National Cancer Center of China released "Cancer incidence and mortality in China, 2022" in December 2024, analyzing data from 22 cancer registries across the country. This study provides a comparative analysis of cancer incidence and mortality trends in China and the United States during the same period, with a focus on sex- and age-specific distributions and long-term changes in cancer patterns. Long-term trends indicate that lung and liver cancer mortality rates in China have declined, primarily due to tobacco control measures and hepatitis B vaccination programs. However, the burden of gastric and esophageal cancers remains substantial. In the United States, mortality rates for colorectal and lung cancers have continued to decline, largely attributed to widespread screening programs and advances in immunotherapy. As economic growth and social development, China’s cancer profile is gradually shifting towards patterns observed in countries with high human development index. However, the prevention and control of upper gastrointestinal cancers remains a critical public health challenge that requires further attention.

ObjectiveTo investigate the different effects of Yunvjian with or without Achyranthis Bidentatae Radix on glucose and lipid metabolism and inflammatory response in diabetic rats with the syndrome of Yin deficiency and internal heat. MethodThe rat model of diabetes due to Yin deficiency and internal heat was established by feeding with a high-sugar and high-fat diet and injection of thyroxine and streptozotocin. The successfully modeled rats were randomized into model control， Yunvjian without Achyranthis Bidentatae Radix （11.8 g·kg^-1）， Yunvjian with Achyranthis Bidentatae Radix （12.8 g·kg^-1）， and Achyranthis Bidentatae Radix （1.0 g·kg^-1） groups （n=10）， and another 10 rats were taken as the normal control group. Each group was administrated with corresponding drugs or saline by gavage for 28 days. The fasting blood glucose （FBG）， fasting insulin （FINS）， total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） in rats were measured.

The histopathological changes of the liver were observed. The expression of lipoxygenase-2 （COX-2） was detected by immunofluorescence. The mRNA levels of nuclear transcription factors-κB （NF-κB）， monocyte chemotactic protein-1 （MCP-1）， and intercellular adhesion molecule-1 （ICAM-1） were determined by real-time polymerase chain reaction （Real-time PCR）.Western blot was employed to determine the protein levels of NF-κB in hibitory protein（IκB） kinase β （IKKβ）， IκBα， and phosphorylated IκBα （p-IκBα） in the liver and the protein levels of NF-κB in the cytoplasm and nucleus. ResultCompared with the normal group， the model group showed elevated levels of FBG， FINS， insulin resistance index， TC， TG， LDL-C， cAMP， T₃， T₄， IL-1β， IL-6， TNF-α， and CRP， up-regulated mRNA levels of NF-κB， MCP-1， and ICAM-1， and up-regulated protein levels of COX-2， p-IκBα， and nuclear NF-κB （P<0.01）. Compared with the model group， Yunvjian without Achyranthis Bidentatae Radix lowered the levels of FBG， FINS， insulin resistance index， TC， TG， LDL-C， cAMP， T₃， T₄， IL-1β， IL-6， TNF-α， and CRP， down-regulated the mRNA levels of NF-κB， MCP-1， and ICAM-1， and down-regulated the protein levels of COX-2， p-IκBα and nuclear NF-κB （P<0.05， P<0.01）. Compared with the Yunvjian without Achyranthis Bidentatae Radix， Yunvjian with Achyranthis Bidentatae Radix showed lowered levels of FBG， FINS， insulin resistance index， and inflammatory cytokines， down-regulated mRNA levels of NF-κB， MCP-1， and ICAM-1， and down-regulated protein levels of p-IκBα and nuclear NF-κB （P<0.05， P<0.01）. ConclusionAchyranthis Bidentatae Radix can enhance the performance of Yunvjian in reducing blood glucose and inhibiting inflammation in diabetic rats with the syndrome of yin deficiency and internal heat by down-regulating the IKK/IκB/NF-κB signaling pathway.

BACKGROUND:As a common complication of diabetes mellitus,male reproductive disorders have received increasing attention in recent years.Ganoderma spore have hypoglycemic,antioxidant and anti-inflammatory effects,but the regulatory mechanism for diabetic testicular tissue has not been fully elucidated. OBJECTIVE:To investigate the effect of ganoderma spore on the PTEN-induced kinase 1/E3 ubiquitin ligase pathway and cell apoptosis in testicular tissue of diabetic rats. METHODS:Forty male Sprague-Dawley rats were randomly divided into normal group,high fat and high sugar group,diabetic group and ganoderma spore group,with 10 rats in each group.The latter three groups were given high fat/high sugar diet until the end of the experiment.After 1 month of high fat/high sugar diet,the diabetic and ganoderma spore groups were given intraperitoneal injection of streptozotocin(30 mg/kg per day)to establish type 2 diabetic rat models.After successful modeling,the ganoderma spore group was intragastrically given ganoderma spore(300 mg/kg per day),and the other groups were given the same amount of normal saline for continuous 12 weeks.The sperm number and morphology were detected.The histopathological changes of the testicle were observed.Serum testosterone and oxidative stress levels in testicular tissue were measured.The levels of PTEN-induced kinase 1,E3 ubiquitin ligase,and anti-nucleoporin p62 were analyzed by immunohistochemistry and the expression of PTEN-induced kinase 1,E3 ubiquitin ligase,anti-nucleoporin p62,programmed cell death-1,microtubule-associated protein light chain 3 Ⅱ/Ⅰ,caspase 3,cleaved-caspase 3 were detected by western blot assay. RESULTS AND CONCLUSION:Compared with the normal group and the high fat and high sugar group,the diabetic group had decreased sperm number(P＜0.01),increased sperm malformation rate(P＜0.01),and decreased serum testosterone level(P＜0.01).Compared with the diabetic group,ganoderma spore intervention could increase the sperm number(P＜0.05),decrease the malformation rate(P＜0.01),and increase the serum testosterone level(P＜0.01).Compared with the normal group and the high fat and high sugar group,the malondialdehyde level in testis tissue was increased in the diabetic group(P＜0.01),while the levels of glutathione deoxidase and superoxide dismutase decreased(P＜0.01).Compared with the diabetic group,the malondialdehyde level in testis tissue was decreased in the ganoderma spore group(P＜0.01),and the levels of glutathione deoxidase and superoxide dismutase increased(P＜0.01).Immunohistochemical staining showed that compared with the normal group and the high fat and high sugar group,the positive expressions of PTEN-induced kinase 1 and E3 ubiquitin ligase in testicular tissue were decreased in the diabetic group,while the positive expressions of anti-nucleoporin p62 were increased.Compared with the diabetic group,the positive expressions of PTEN-induced kinase 1 and E3 ubiquitin ligase in testicular tissue e were increased in the ganoderma spore group,while the positive expression of anti-nucleoporin p62 was decreased.Western blot assay results indicated that compared to the normal group and the high fat and high sugar group,the expression of PTEN-induced kinase 1 and E3 ubiquitin ligase,programmed cell death-1 and the ratio of microtubule-associated protein light chain 3 Ⅱ/Ⅰ protein were decreased in the diabetic group(P＜0.05 or P＜0.01),while the expressions of anti-nucleoporin p62,caspase3 and cleaved-caspase3 were increased(P＜0.01).Compared with the diabetic group,ganoderma spore intervention could elevate the expression of PTEN-induced kinase 1 and E3 ubiquitin ligase,programmed cell death-1 and the ratio of microtubule-associated protein light chain 3 Ⅱ/Ⅰ protein(P＜0.05 or P＜0.01)as well as reduce the expressions of anti-nucleoporin p62,caspase3 and cleaved-caspase3(P＜0.05 or P＜0.01).Overall,ganoderma spores may activate the PTEN-induced kinase 1/E3 ubiquitin ligase pathway to enhance autophagy in testicular tissue and reduce apoptosis in tissue cells,so as to protect testicular tissue.

ABATRACT OBJECTIVE To utilize the pharmacophore model-molecular docking combined with the virtual screening strategy of free energy calculation and the chemical bioinformatics method of traditional Chinese medicine in cell biology experiments to investigate the components of Guiqi Baizhu prescription that target phosphatidylinositol 3-kinase(PI3K) and inhibit the proliferation of uveal melanoma(UM) cells. METHODS The pharmacophore model of PI3K inhibitor was constructed, and the compounds of Guiqi Baizhu prescription were virtual screened. The components that fit the pharmacophore model were calculated by molecular docking and binding free energy, and the potential inhibitory components were selected for biological experimental evaluation. The effects of potential inhibitory components on UM cell proliferation were detected by CCK-8 and clonal formation assay. Flow cytometry was used to detect the cell cycle and apoptosis of UM cells. The mitochondrial membrane potential of UM cells was detected using JC-10 staining. The expressions of PI3K and downstream pathway proteins were detected by Western blotting.RESULTS The pharmacophore model included 2 hydrogen bond receptors, 2 aromatic ring centers, and exclusion volumes. The results of the CCK-8 experiment showed that quercetin, tangerine, and nobiletin at concentrations of 10, 20, 40, 80 μmol·L−1, and cyrtin at concentrations of 20, 40, 80 μmol·L−1, were able to inhibit the proliferation of UM cells. The clonal formation experiment showed that quercetin, tangerine, nobiletin, and morusin, at different concentrations, could significantly inhibit the clonal proliferation of UM cells. Flow cytometry showed that UM cells were arrested in the G0/G1 phase by tangeretin and quercetin, while UM cells were arrested in the G2/M phase by nobiletin and morusin. The results of JC-10 staining showed that quercetin, nobiletin, tangeretin, and morusin could reduce the mitochondrial membrane potential of UM cells. Western blotting results showed that 4 compounds could target PI3K, but their downstream pathways were different.CONCLUSION Based on the method of chemical bioinformatics in traditional Chinese medicine, this study explores the material basis for the inhibition of UM cell proliferation by the Guiqi Baizhu prescription. It also provides insights for the modern development of traditional Chinese medicine prescription.

With the extensive application of uranium in military, industrial and civil fields, the possibility of human exposure to uranium has become increasingly likely. When uranium is accidentally released into the environment, it can enter the human body by various pathways and accumulate in the kidneys, leading to proximal tubule epithelial cell damage or even death, and in severe cases, nephrotoxicity. Uranium exerts both chemical and radiological toxicity, with its kidney-damaging effects primarily attributed to chemical toxicity. Low-level uranium exposure causes mild kidney damage, while prolonged or high-level exposure alters kidney structure and biomarker level of uranium-induced nephrotoxicity (such as creatinine, urea nitrogen and kidney injury molecule-1, etc.). Uranium exposure also induces DNA damage and mutations, kidney inflammation, and renal cell autophagy. Current research on uranium nephrotoxicity primarily focuses on uranium-induced mitochondrial dysfunction, which leads to oxidative stress and apoptosis (mainly by mitochondrial and endoplasmic reticulum pathway), ultimately causing renal tissue damage. However, the molecular mechanisms underlying uranium-induced kidney toxicity remain incomplete. Future research on mechanism of uranium-induced cell damage, especially metabolism, intracellular distribution, and additional mechanisms, remains a long-term and challenging endeavor.

OBJECTIVE To explore the effectiveness, potential mechanism and compatibility characteristics of efficacy groups of Dunhuang medical prescription Daxiefei decoction in preventing and treating pneumonia based on chemical bioinformatics method. METHODS To study the effect of Daxiefei decoction freeze-dried powder solution on the proliferation activity of lung epithelial cells through cell experiments. Daxiefei decoction was divided into three groups: clearing away heat group, resolving phlegm group, and nourishing Yin group according to its efficacy characteristics. The chemical components of Daxiefei decoction were obtained by TCMSP database and literature search, and the targets were predicted in Swiss Target Prediction database. Pneumonia disease targets were obtained by DrugBank, TTD, Genecards and DisGeNET databases. STRING database and Cytoscape were used to construct the intersection target interaction network and "drug-component-target- pathway" network and DAVID database was used for KEGG pathway enrichment analysis. The network was used to analyze the scientific connotation of the compatibility of efficacy groups. Furthermore, molecular docking was used to evaluate the target-compound affinity and molecular dynamics was used to explore the dynamic molecular mechanism. RESULTS Cell experiments showed that Daxiefei decoction can maintain the proliferation of lung epithelial cells, reverse the decrease of mitochondrial activity induced by LPS and reduce apoptosis. Complex network analysis showed that the pathways enriched by the three functional groups contained in Daxiefei decoction were mainly distributed in two modules: inflammation regulation and reducing airway mucus hypersecretion. Each module was connected by a common target gene and had its own focus. The results of molecular docking showed that the components quercetin, baicalein, isorhamnetin etc. might be the effective multi-target components of Daxiefei decoction. SRC, EGFR, PPARA etc. had good affinity with each potential active component, which might be a potential target of Daxiefei decoction for preventing and treating pneumonia. Molecular dynamics simulation showed that the potential active component quercetin formed stable intermolecular interactions with SRC. CONCLUSION This study initially reveal the material basis and molecular mechanism of Daxiefei decoction in the prevention and treatment of pneumonia. It also explores the scientific connotation of Daxiefei decoction in the prevention and treatment of pneumonia with different efficacy groups, and its modern development and clinical application provide chemical bioinformatics basis.
