Objective The aim of this study was to investigate the correlation between the interaction of uric acid and inflammatory factors and hyperuricemia in overweight/obese patients. Methods The personnel with hyperuricemia who underwent physical examination in our hospital from September 2021 to September 2022 were selected as the study subjects, and they were divided into 100 cases of overweight group and 90 cases of obese group according to the BMI index; 120 cases of healthy and non-hyperuricemic personnel were randomly selected as the control group; venous blood of the three groups was collected in 5 mL after 8 h of fasting, and were tested respectively for serum uric acid, lipid indexes and inflammatory factors: IL-6, IL-2, IFN-γ, TNF-α, IL-4, IL-10. Results Glucose, triglycerides, total cholesterol, and LDL were significantly higher in the obese group versus the overweight group (P<0.001), while HDL was significantly lower than the control group (P<0.001), and these changes were more pronounced in the obese group (P<0.001).The Pearson correlation coefficient pointed out that the levels of serum uric acid in patients with hyperuricosuric acid were significantly associated with the pro-inflammatory factors IL- 6, IL-2, IFN-γ, and TNF-α were significantly positively correlated (P<0.001), whereas they were significantly negatively correlated with the anti-inflammatory factors IL-4, IL-10 (P<0.001). Conclusion High uric acid levels in overweight/obese patients can cause enhanced inflammatory responses and reduced expression levels of anti-inflammatory factors, and the interaction between uric acid and pro-inflammatory factors aggravates the condition of patients with hyperuricemia.

Objective:To investigate the influences of lupinol on the proliferation,apoptosis and invasion of cer-vical cancer cells by regulating autophagy mediated by phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)/mammalian target of rapamycin(mTOR)pathway.Methods:The proliferation rate of human cervical cancer cell line HeLa cells treated with 0,10,25,50,70,90 μmol/L lupinol was determined,and the appropriate concentration of lupinol was screened out.HeLa cells cultured in vitro were randomly grouped into control group,low-dose lupinol group,high-dose lupinol group,740 Y-P group(PI3K activator),and high-dose lupinol+740 Y-P group.After group intervention with lupinol and 740 Y-P,MDC fluorescence staining was used to detect the forma-tion of autophagic vacuolation of HeLa cells in each group;western blot was used to detect the expression of au-tophagy and PI3K/AKT/mTOR pathway-related proteins in HeLa cells in each group.HeLa cells cultured in vitro were randomly grouped into control group,low-dose lupinol group,high-dose lupinol group,high-dose lupinol+rapamycin(Rapa),and high-dose lupinol+3-methyladenine(3-MA)group.After the intervention of high dose of lupinol,Rapa and 3-MA,the proliferation of HeLa cells in each group was detected by MTT assay and plate colony formation assay;flow cytometry was used to detect the apoptosis of HeLa cells in each group;transwell assay was used to detect the invasion of HeLa cells in each group;western blot was used to detect the expressions of proliferation,apoptosis and epithelial-mesenchymal transition-related proteins in HeLa cells in each group.Re-sults:Compared with the control group,the relative content of autophagic vacuoles,the protein expressions of Mi-crotubule-associated protein 1A/1 B-light chain 3(LC3)Ⅱ/LC3Ⅰ,and Beclin-1 in the low and high dose lupinol groups were all increased(P＜0.05),the phosphorylated PI3K(p-PI3K)/PI3K,phosphorylated AKT(p-AKT)/AKT,and phosphorylated mTOR(p-mTOR)/mTOR decreased(P＜0.05);the relative content of autophagic vac-uoles,the protein expressions of LC3Ⅱ/LC3Ⅰ,and Beclin-1 in the high-dose lupinol group were further increased compared with the low-dose lupinol group(P＜0.05),the p-PI3K/PI3K,p-AKT/AKT,and p-mTOR/mTOR were further decreased(P＜0.05);the relative content of autophagic vacuoles,the protein expressions of LC3Ⅱ/LC3Ⅰ,and Beclin-1 in 740 Y-P group decreased compared with the control group(P＜0.05),the p-PI3K/PI3K,p-AKT/AKT,and p-mTOR/mTOR increased(P＜0.05).Compared with the high-dose lupinol group,the relative content of autophagic vacuoles,the protein expressions of LC3Ⅱ/LC3Ⅰ,and Beclin-1 in the high-dose lupinol+740 Y-P group decreased(P＜0.05),the p-PI3K/PI3K,p-AKT/AKT,and p-mTOR/mTOR increased(P＜0.05).Com-pared with the control group,the cell proliferation rate,colony formation rate,invasion number,and the protein ex-pressions of proliferating cell nuclear antigen(PCNA),B cell lymphoma 2(Bcl-2)and Vimentin in the low and high dose groups of lupinol were all decreased(P＜0.05),the apoptosis rate,and the protein expressions of Bcl-2 as-sociated x protein(Bax)and zonula occludens protein 1(ZO-1)were all increased(P＜0.05);compared with the low-dose lupinol group,the cell proliferation rate,colony formation rate,invasion number,and the protein expres-sions of PCNA,Bcl-2 and Vimentin in the high-dose lupinol group were further decreased(P＜0.05),the apopto-sis rate,and the protein expressions of Bax and ZO-1 were further increased(P＜0.05).Compared with the high-dose lupinol group,the cell proliferation rate,colony formation rate,invasion number,and the protein expres-sions of PCNA,Bcl-2 and Vimentin in the high-dose lupinol+Rapa group were increased(P＜0.05),the apopto-sis rate,and the protein expressions of Bax and ZO-1 were decreased(P＜0.05);the cell proliferation rate,colo-ny formation rate,invasion number,and the protein expressions of PCNA,Bcl-2 and Vimentin in the high-dose lu-pinol+3-MA group were decreased(P＜0.05),the apoptosis rate,and the protein expressions of Bax and ZO-1 were increased(P＜0.05).Conclusions:Lupinol induces protective autophagy by inhibiting the PI3K/AKT/mTOR pathway,thereby promoting the apoptosis of cervical cancer cells and inhibiting their proliferation and inva-sion.Activation of autophagy attenuates the effects of lupinol on the proliferation,apoptosis and invasion of cervi-cal cancer cells.

Methods: Patients with dry eye who were treated in the Ophthalmology Ward and Outpatient Department of the First Hospital of Hunan University of Chinese Medicine from October 1, 2020, to October 30, 2021 were enrolled as the research participants in the study. They were assigned to two groups based on traditional Chinese medicine (TCM) syndrome types: heat stagnation in liver meridian pattern group and Qi-Yin deficiency pattern group. Healthy volunteers who underwent health check-ups in the Health Management Department were included as healthy group following the random number table method. The tears of the patients and the healthy volunteer participants were tested by high-performance liquid chromatography-mass spectrometry (LC-MS). The differential metabolites were screened out by multivariate statistical analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment was performed on the differential metabolites. Finally, the association analysis of differential proteins and metabolites was conducted to verify and supplement the metabolites. Results: A total of 32 dry eye patients were enrolled, including 16 cases with heat stagnation in liver meridian pattern and 16 cases with Qi-Yin deficiency pattern. Fourteen healthy volunteers were included as healthy group. There were no significant differences in baseline characteristics among the three groups (P > 0.05). A total of 412 biomarkers were determined in Qi-Yin deficiency pattern group, mainly including lipids, lipid-like molecules, organic acids and their derivatives, organic heterocyclic compounds, and nucleosides and their analogues. For heat stagnation in liver meridian pattern group, 112 metabolites were determined, mainly including organic acids and their derivatives, lipids, and lipid-like molecules. The KEGG enrichment results of pathways and the relative content analysis of differential markers demonstrate that purine metabolism and caffeine metabolism pathways are common metabolic characteristics of all dry eyes. Among them, deoxyinosine monophosphate (dIMP) and 2-(formamido)-N1-(5-phospha-D-ribosyl) acetamidine can serve as their biomarkers. The main characteristics of Qi-Yin deficiency syndrome pattern were the significant enhancement of metabolic pathways such as lysine degradation, ovarian steroidogenesis, cholesterol metabolism, pyrimidine metabolism, and bile secretion (P < 0.05). Dry eye associated with the heat stagnation in liver meridian pattern is mainly characterized by inhibition of the valine, leucine, and isoleucine biosynthesis pathways (P < 0.05). Conclusion Metabolomics can be used as an effective basis for TCM syndrome classification. Different patterns of dry eye syndrome exhibit typical characteristics in the types and concentrations of metabolites, which correspond to the syndrome classification in TCM. This study initially confirms the rationality of TCM syndrome classification and provides significant reference for the mechanism of dry eye and drug development.
