GO function analysis revealed 2 665 related pathways, and KEGG pathway enrichment analysis revealed 188 related pathways. Molecular docking results showed that curcumin had good binding ability with the targets of mitogen-activated protein kinase 3 (MAPK3), interleukin (IL) 6, serine/threonine kinase 1 (AKT1), vascular endothelial growth factor A (VEGFA), signal transducer and activator of transcription 3, albumin, Jun proto-oncogene, tumor necrosis factor (TNF), IL1B, tumor protein p53, C-C motif chemokine ligand 2 and fibronectin 1. Conclusion The therapeutical effects of curcumin on silicosis were implemented through multi-targets and multi-pathways. Curcumin may play a role in the treatment of silicosis by binding to the core targets MAPK3, IL6, AKT1, VEGFA and TNF and regulating the MAPK, IL6, TNF, phosphatidylinositol 3-kinase/protein kinase B and VEGF signaling pathways.

Objective To analyze the occupational health status of radiation workers in Guangdong Province. Methods A total of 8 913 radiation workers who underwent occupational medical examination (OME) in Guangdong Province Hospital for Occupational Disease Prevention and Treatment in 2020 were selected as the exposure group, and 2 024 non-radiological workers who underwent health examination in the same hospital in the same period of time were selected as the control group using convenient sampling method. The study analyzed the prevalence of abnormalities in thyroid, eye lens, blood pressure, complete blood count and micronucleus in individuals of the two groups. Results The abnormal rates of eye lens, blood pressure and complete blood count in the radiation workers in the exposure group were higher than those in the control group (23.3% vs 8.0%, 18.6% vs 9.0%, 18.1% vs 8.5%, all P<0.01). However, there was no significant difference in the abnormal rates of thyroid and micronucleus in workers between these two groups (12.8% vs 11.5%, 0.1% vs 0.0%, all P>0.05). The abnormal rates of thyroid, eye lens and blood pressure in radiation workers increased with the exposure period of radiation (all P<0.05). Conclusion Long-term exposure to low-dose ionizing radiation have certain effects on the thyroid, eye lens, and blood pressure of radiation workers, with a time-effect relationship of years of radiation work.

Objective:To investigate the relationship between the E2 and E4 alleles of apolipoprotein E (apoE) gene and myocardial infarction (MI) in type 2 diabetes Mellitus (T2DM) patients, and to explore the relationship between apoE polymorphism and blood lipid metabolism.Methods:This case control study was conducted from August 2016 to March 2020 in China-Japan Friendship Hospital, 3 459 inpatients with T2DM were included including 3 044 patients without MI (T2DM group) and 415 patients with MI (T2DM+MI group). Real time fluorescent quantitative PCR was used to detect apoE polymorphism. Automatic biochemical analyzer was used to detect lipid levels. Logistic regression analyses were performed to determine the association of apoE with risk of MI in patients with T2DM.Results:(1) The frequency of E4 allele in T2DM+MI group (12.29%, 102/830) was significantly higher than in T2DM group (9.13%,556/6 088), while the frequency of E2 allele in T2DM+MI group (7.35%,61/830) was significantly lower than that in T2DM group (8.21%,500/6 088), P=0.012. Logistic regression analyses showed that E4 allele carrier (E3/E4+E4/E4) faced a higher risk for MI in T2DM patients ( OR=1.48, 95% CI 1.14-1.92, P=0.003), while E2 allele carrier(E2/E3+E2/E2)did not face a higher risk of MI in T2DM patients ( OR=0.88, P=0.642). (2) The levels of apoE polymorphism and blood lipid: The levels of TC, LDL-C and apoB increased in the order of E4 allele, wild type and E2 allele ( P<0.05). The levels of HDL-C, apoA1 and apoE decreased in the order of E4 allele, Wild type and E2 allele ( P<0.05). Conclusion:The E4 allele is a risk factor for MI in T2DM patients, and apoE polymorphism can affect blood lipid level in this patent cohort.

Diabetes have been shown to cause progressive neuronal injury with pain and numbness via advanced glycation end-products (AGEs)-induced neuronal cell apoptosis; however, the valuable drug targets for diabetic neuropathy have been poorly reported so far. In this study, we discovered a natural small-molecule schisandrol A (SolA) with significant protective effect against AGEs-induced neuronal cell apoptosis. ATP6V0D1, a major subunit of vacuolar-type ATPase (V-ATPase) in lysosome was identified as a crucial cellular target of SolA. Moreover, SolA allosterically mediated ATP6V0D1 conformation via targeting a unique cysteine 335 residue to activate V-ATPase-dependent lysosomal acidification. Interestingly, SolA-induced lysosome pH downregulation resulted in a mitochondrial-lysosomal crosstalk by selectively promoting mitochondrial BH3-only protein BIM degradation, thereby preserving mitochondrial homeostasis and neuronal cells survival. Collectively, our findings reveal ATP6V0D1 is a valuable pharmacological target for diabetes-associated neuronal injury via controlling lysosomal acidification, and also provide the first small-molecule template allosterically activating V-ATPase for preventing diabetic neuropathy.

Mitochondrial shape rapidly changes by dynamic balance of fusion and fission to adjust to constantly changing energy demands of cancer cells. Mitochondrial dynamics balance is exactly regulated by molecular motor consisted of myosin and actin cytoskeleton proteins. Thus, targeting myosin-actin molecular motor is considered as a promising strategy for anti-cancer. In this study, we performed a proof-of-concept study with a natural-derived small-molecule J13 to test the feasibility of anti-cancer therapeutics
