Objective:
To establish a fluorescence method based on turncated aptamer for the determination of bisphenol A in water.
Methods:
The bisphenol A truncated aptamer containing 38 bases was selected as a recognition module, and was modified with the fluorophore 6-FAM at the 5'end. The 3'end of the complementary sequence cDNA was modified with the quencher DABCYL. The standard solutions of bisphenol A and interfering compounds were configured. The detection system was established after optimizing the number of bases in cDNA, the concentration ratio of truncated aptamer to cDNA, the incubation temperature and time, and the pH of the buffer. The specificity and recovery experiments were carried out.
Results:
When the complementary sequence cDNA included 9 bases, the concentration ratio of the truncated aptamer to cDNA was 1:1.5, the pH value of the buffer solution was 7.5, the cDNA was incubated at 55 ℃ for 60 minutes, in the concentration range of 10-75 pmol/L, the linear regression equation was y=2 230.7x+110 825, the correlation coefficient was 0.926. The limits of detection was 3.3 pmol/L. The difference values of fluorescence intensity between tetrabromobisphenol A, estradiol, estriol, bisphenol S and bisphenol A were obviously different, so there was no significant interference to the test result. The recovery rates were 97.8%, 98.8% and 102.3% with the spiked concentrations of 20.0, 40.0 and 60.0 pmol/L. The relative standard deviations were 4.4%, 2.1% and 2.6% (n=5), respectively.
Conclusion
The fluorescence method based on turncated aptamer has the advantages of easy operation, high sensitivity and specificity, which can be used for the determination of bisphenol A in water.

HMGB1's role in tumors is complex and diverse,and it exerts its biological function by combining with different receptors.One of the receptors is called RAGE,which is localized to the cell membrane and binds to HMGB1 released outside the cell.The HMGB1/RAGE axis promotes tumor development,moreover,tumor development and its drug resistance are closely related to inflammation.This article mainly reviews the molecular mechanism of HMGB1/RAGE axis in pro-inflammatory and protumor effects in pancreatic,colorectal and liver cancers.We also summarize the research progress of papaverine and its derivatives for the treatment of HMGB1/RAGE axis in tumor inflammation,with aims of providing new ideas for exploring the molecular mechanism of action in tumor inflammation,and providing a new theoretical basis for the research of HMGB1/RAGE axis therapeutics.

Post-stroke depression (PSD) is an important mental complication of stroke, affecting nearly 1/3 of stroke patients, seriously affecting patients' functional recovery and quality of life, and is associated with increased mortality of stroke patients. Traditional antidepressant treatments include medication and psychotherapy, but there may be problems with adverse reactions, tolerance, or limited effectiveness. Repetitive transcranial magnetic stimulation (rTMS), as a non-invasive neuroregulatory technique, offers a new treatment option for patients with PSD. This article reviews the application of rTMS in the treatment of PSD and its possible mechanism.

Oral diseases,such as periodontitis,salivary gland diseases,and oral cancers,significantly challenge health conditions due to their detrimental effects on patient's digestive functions,pronunciation,and esthetic demands.Delayed diagnosis and non-targeted treatment profoundly influence patients'prognosis and quality of life.The exploration of innovative approaches for early detection and precise treatment represents a promising frontier in oral medicine.Exosomes,which are characterized as nanometer-sized extracellular vesicles,are secreted by virtually all types of cells.As the research continues,the complex roles of these intracellular-derived extracellular vesicles in biological processes have gradually unfolded.Exosomes have attracted attention as valuable diagnostic and therapeutic tools for their ability to transfer abundant biological cargos and their intricate involvement in multiple cellular functions.In this review,we provide an overview of the recent applications of exosomes within the field of oral diseases,focusing on inflammation-related bone diseases and oral squamous cell carcinomas.We characterize the exosome alterations and demonstrate their potential applications as biomarkers for early diagnosis,highlighting their roles as indicators in multiple oral diseases.We also summarize the promising applications of exosomes in targeted therapy and proposed future directions for the use of exosomes in clinical treatment.
