OBJECTIVE: To evaluate the clinical efficacy and safety of Shenzhu Guanxin recipe granules(参术冠心颗粒, SGR) in treating patients with intermediate coronary lesions(ICL), and to investigate the potential mechanism though a transcriptome sequencing approach. METHODS: ICL patients with Qi deficiency and phlegm stasis were adopted and randomly assigned to a case group or a control by random number generator in a 1∶1 randomization ratio to evaluate the clinical efficacy. RESULTS: There was no significant difference between the two groups in coronary computed tomography angiography related indexes in the two groups before and after intervention. Through the gene chip expression analysis, it is finally concluded that there are 355 differential mRNAs(190 up-regulated genes and 165 down regulated genes) when compared the SGR group and placebo group. Through protein-protein interaction network analysis of differentially expressed genes, 10 hub genes were finally obtained: CACNA2D2, CACNA2D3, DNAJC6, FGF12, SGSM2, CACNA1G, LRP6, KIF25, OXTR, UPB1. CONCLUSIONS: SGR combined with Western Medicine can be safely used to treat ICL patients with Qi deficiency and phlegm stasis. The possible mechanism of action and relevant gene loci and pathway were proposed.

Thyroid nodules are a common clinical problem caused by various factors,including environmental and nutritional factors and genetic *** environment can modulate and influence not only the risk of thyroid nodules but also the severity of disease in humans[1].The environment is awash with elements,and all mineral elements,including heavy metals and trace elements,are considered potentially toxic.A significantly higher incidence of thyroid cancer has been reported in populations exposed to low doses of metallic elements in volcanic areas over a long period[2].As research on thyroid disorders continues,it is becoming clear that abnormalities in trace elements in the body can affect the development of thyroid-related disorders.

Enhanced SERS aptasensor for sensitive detection of saxitoxin based on HAuCl/HOreaction system and Pt/Au nanozyme

引用

Food Science and Human Wellness 2024年

作者： Yueqing Li Xuemei Tang Wei Zeng ting wu Long wu School of Food Science and Engineering Key Laboratory of Tropical Fruits and Vegetables Quality and Safety for State Market Regulation Hainan University

Saxitoxin （STX） is a marine biotoxin produced by cyanobacteria and methanobacteria， which is harmful to humans and aquatic organisms. Therefore， it is urgent to establish an efficient， sensitive and selective method for the screening of STX. In this paper， based on the HAuCl4/H2O2reaction system， gold nanoparticles （Au NPs） decorated Fe3O4magnetic beads (Fe3O4@Au NPs) and Pt/Au nanozymes （Pt/Au NZs）， an enhanced SERS aptasensor was proposed for sensitive and selective detection of STX. Firstly， SERS tag （4-MBA） and aptamer modified Fe3O4@Au NPs were hybridized with complementary DNA modified Pt/Au NZs （Pt/Au-cDNA） to form the specific complexes. Wherein， aptamer acted as capture agent to specifically recognize STX， Pt/Au NZs catalyzed HAuCl4/H2O2reaction to enhance SERS signal， and Fe3O4facilitated the magnetic separation and simple detection operations. The SERS aptasensor achieved sensitive detection of STX with a wide linear range from 0.02 μmol/L to 0.8 μmol/L and a low detection limit of 13 nmol/L （LOD， S/N=3）. To evaluate the performance of this method， STX were detected in the spiked seafood samples with recoveries from 78.75% to 150% with relative errors below 6.52%. Besides， the SERS aptasensor behaved good stability and repeatability， revealing its promising potential in STX detection and food safety detection.
