Resistance to poly adenosine diphosphate (ADP)-ribose polymerase inhibitor (PARPi) presents a considerable obstacle in the treatment of ovarian cancer. F-box and tryptophan-aspartic (WD) repeat domain containing 11 (FBXW11) modulates the ubiquitination of growth-and invasion-related factors in lung cancer, colorectal cancer, and osteosarcoma. The function of FBXW11 in PARPi therapy is still ambiguous. In this study, RNA sequencing (RNA-seq) showed that FBXW11 expression was raised in ovarian cancer cells that had been treated with PARPi. FBXW11 was abnormally expressed at low levels in high-grade serous ovarian cancer (HGSOC) tissues, and low levels of FBXW11 were associated with shorter overall survival (OS) and progression-free survival (PFS) in HGSOC patients. Overexpressing FBXW11 made ovarian cancer more sensitive to PARPi, while knocking down FBXW11 made it less sensitive. The four-dimensional (4D) label-free quantitative proteomic analysis revealed that FBXW11 targeted S100 calcium binding protein A11 (S100A11) and promoted its degradation through ubiquitination. The increased degradation of S100A11 led to less efficient DNA damage repair, which in turn contributed to increased PARPi-induced DNA damage. The role of FBXW11 in promoting PARPi sensitivity was also confirmed in xenograft mouse models. In summary, our study confirms that FBXW11 promotes the susceptibility of ovarian cancer cells to PARPi via affecting S100A11-mediated DNA damage repair.

Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

This study investigated the association between serum 25(OH)D 3 levels and cardiovascular risk-related indicators. 4 727 participants aged 20 and above from the National Health and Nutrition Examination Survey 2015-2018 database were enrolled. Body mass index, hypersensitive C-reactive protein, high density lipoprotein cholesterol, systolic blood pressure, waist-height ratio, and total cholesterol were selected as the research indicators. Weighted multiple linear regression models, subgroup analyses, smooth curve fitting, and saturation threshold effect analyses were employed to explore the relationship between serum 25(OH)D 3 and these indicators. The results showed that after full adjustment for covariates, every 1 nmol/L increase in serum 25(OH)D 3, the changes in β (95% CI) values for body mass index(BMI), hypersensitive C-reactive protein(hs-CRP), systolic blood pressure(SBP), waist-height ratio(WHtR), high density lipoprotein cholesterol(HDL-C), and total cholesterol(TC) were -0.05 (-0.06, -0.04) kg/m 2, -0.01 (-0.02, -0.01) mg/L, -0.02 (-0.04, -0.01) mmHg, -0.000 7 (-0.000 8, -0.000 6), 0.10 (0.08, 0.11) mg/dl, and 0.08 (0.04, 0.12) mg/dl, respectively. Female participants were more sensitive to changes in serum 25(OH)D 3, while participants aged 60 and above were relatively less sensitive. The relationship between serum 25(OH)D 3 and these indicators partially exhibited nonlinear patterns across different gender and age subgroups. The saturation threshold effect analysis revealed 8 meaningful inflection points. In summary, vitamin D has a close association with cardiovascular risk-related indicators.

ObjectiveTo investigate the mechanism of Biejiajian Wan in the intervention of primary liver cancer based on long non-coding RNA SNHG5 （lncRNA SNHG5）/micro RNA-26a-5p （miRNA-26a-5p）/glycogen synthase kinase-3β （GSK-3β） signal axis. MethodDouble luciferase reporting assay was used to verify the targeted interaction between lncRNA SNHG5 and miRNA-26a-5p， miRNA-26a-5p， and GSK-3β in HepG2 cells. Nude-mouse transplanted tumor model of human HepG2 were established and randomly divided into model group， Biejiajian Wan low-dose group （0.5 g·kg^-1）， medium-dose group （1.0 g·kg^-1）， and high-dose group （2.0 g·kg^-1）， and sorafenib group （100 mg·kg^-1）， with 10 mice in each group. The mice were given intragastric administration of normal saline or drug for 28 days， and the tumor volume was measured at different time. Hematoxylin-eosin （HE） staining was used to observe the histological changes of tumors. The nucleic acid levels of lncRNA SNHG5， miRNA-26a-5p， GSK-3β， and β-catenin mPNA in tumor tissue were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. The protein expression levels of GSK-3β and β-catenin in tumor tissue were detected by western blot. ResultCompared with the SNHG5-WT （wild type） + miRNA NC （negative control） group， the relative luciferase activities of the SNHG5-WT + miRNA-26a-5p mimic group were decreased （P<0.05）. Compared with the GSK-3β-WT + miRNA NC group， the relative luciferase activity of the GSK-3β-WT + miRNA-26a-5p mimic group was decreased （P<0.05）. Compared with the model group， the tumor volume of Biejiajian Wan low-dose， medium-dose， and high-dose groups was significantly decreased （P<0.05， P<0.01）. Compared with the model group， the cells in the tumor tissue of nude mice in each dose group of Biejiajian Wan were sparsely arranged with necrocytosis， which showed concentration-dependent changes. Compared with the model group， the expression levels of lncRNA SNHG5， GSK-3β， and β-catenin were decreased （P<0.05， P<0.01）， while the expression of miRNA-26a-5p was increased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. Compared with the model group， the protein expression levels of GSK-3β and β-catenin were decreased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. ConclusionBiejiajian Wan may affect the necrosis of liver cancer cells through lncRNA SNHG5/miRNA-26a-5p/GSK-3β signal axis and thus play an anti-tumor role. This research will provide more theoretical basis for the clinical application of Biejiajian Wan.

Objectiveto investigate the differential expression of intestinal flora and serum metabolites and potential biomarkers in patients with pre-diabetic sputum syndrome. MethodA total of 34 patients with pre-diabetic sputum syndrome were included as the phlegm syndrome group，and 37 healthy people were selected as the normal group. Serum and fecal samples of the two groups were collected，and liquid chromatography-mass spectrometry （LC-MS） non-targeted metabolomics and 16S rRNA high-throughput sequencing technology were used to detect serum metabolites and different intestinal flora of the two groups and explore the relationship among pre-diabetic sputum syndrome，serum metabolites，and intestinal flora. ResultIn the distribution of disease syndrome elements in the phlegm syndrome group，the first five disease syndrome elements in terms of frequency and proportion were dampness （73.53%），Qi stagnation （58.82%），Yin deficiency （50.00%），blood stasis （41.18%），and heat （35.29%）. According to the frequency and proportion of disease location syndrome elements，the first three main disease location syndrome elements were spleen （100.00%），liver （41.18%），and kidney （23.53%）. The results of 16S rRNA high-throughput sequencing showed that there were 44 different intestinal flora between the two groups. In order genus，there were significant differences in Bifidobacterium，Veillonococcus，and Roseococcus between the two groups （P<0.05）. The diversity，abundance，and evenness of intestinal flora in the phlegm syndrome group were lower than those in the normal group，with the difference not statistically significant. There was no significant difference in the community structure between two groups. The results of serum metabolomics showed that there were 13 differential metabolites in the two groups，which were mainly concentrated in amino acid metabolism，bile secretion，bile acid biosynthesis，and lipid metabolism （P<0.05）. The correlation among differential metabolites，intestinal flora，and syndrome elements was analyzed，and the results showed that ① lysine was positively correlated with spleen，Yin deficiency，and blood stasis，while taurocholic acid was positively correlated with liver，kidney，blood stasis，and dampness，and there was a positive correlation between taurocholic acid and yin deficiency and heat. The taurochenodeoxycholic acid was positively correlated with liver and dampness，and there was a negative correlation between arachidonic acid and dampness，as well as a positive correlation between glucose and spleen and blood stasis. ② Clostridium was positively correlated with spleen，kidney，Yin deficiency，and Qi stagnation. Rosepiella was negatively correlated with spleen，and Sutterella was negatively correlated with dampness. Bacteroides was negatively correlated with the spleen and kidney，and Bifidobacterium was negatively correlated with the spleen and dampness. ③ Bifidobacterium was positively correlated with glycine，threonine，lysine，and deoxycholic acid significantly，negatively correlated with cholic acid significantly，and positively correlated with taurochenodeoxycholic acid and pyruvic acid. Clostridium was positively correlated with glycine significantly and positively correlated with threonine and lysine. Lachnospira was negatively correlated with glycine，threonine，and pyruvic acid. Lysine was also negatively correlated with Faecalibacterium and Eubacterium ventriosum and positively correlated with Megamonas. There was a positive correlation between taurocholic acid and glycine bile acid and Campylobacter，between taurochenodeoxycholic acid and Veillonococcus，and between glucose and Rosepiella and Eubacterium ventriosum. There was a negative correlation between pyruvic acid and Escheria-Shigella and between taurochenodeoxycholic acid and Prevotella. Conclusionthere are differences in intestinal flora and serum metabolites between patients with pre-diabetic sputum syndrome and healthy people. The intestinal flora and metabolites have been disturbed in the stage of pre-diabetes，Bifidobacterium，Clostridium，Lachnospira，glycine，threonine，and lysine may be the breakthrough to explore the development of pre-diabetic sputum syndrome.
