Multidisciplinary non-surgical treatment of advanced periodontitis:A case report

BACKGROUND Patients with severe periodontitis often require multidisciplinary treatment to achieve healthy periodontal tissue,normal occlusion,and optimal aesthetics.In the present study,we aimed to evaluate the efficacy of multidisciplinary non-surgical treatment in a patient with stage IV/grade C periodontitis,malocclusion,and dentition defects.CASE SUMMARY A 47-year-old woman visited our periodontology department due to teeth mobility problems and difficulties chewing food.The patient had no history of drug allergies or systemic disease.Initial therapy involved scaling and root planning with a Gracey scaler and periodontal ultrasonic therapeutic apparatus using a periodontal endoscope(Perioscopy,Zest Dental Solutions,United States)to control the periodontal inflammation prior to treatment.Five months later,orthodontic treatment was then performed to treat occlusion and overall aesthetics.After completion,a Maryland bridge was used to restore Nos.22,31,and 41 teeth.Florida probing(Florida probe,United States)was performed every 2-3 mo to evaluate the periodontal condition throughout treatment.Overall,multidisciplinary non-surgical treatment resulted in satisfactory aesthetic results with healthy periodontal tissue and stable occlusion.CONCLUSION In some patients with stage IV/grade C periodontitis,systematic and sequential non-surgical treatment can provide excellent therapeutic results.

Transcriptome sequencing analysis of ursolic acid-mediated proliferation suppression on cutaneous T-cell lymphoma cells

Background:Ursolic acid is a triterpenoid compound found in natural plants that exhibits antiproliferative effects in various cancer cells.Our study is the first to demonstrate the strong inhibitory effects of ursolic acid on the proliferation of cutaneous T-cell lymphoma(CTCL)cells.We aimed to further investigate the underlying mechanism of the proliferation inhibition induced by ursolic acid in CTCL cells using transcriptome sequencing.Methods:Cell counting kit-8 assays were used to observe the effects of six traditional medicine monomers on the proliferation of CTCL cells.Transcriptome sequencing was used to identify differentially expressed genes after ursolic acid treatment.Bioinformatics analysis was performed to determine the potential mechanism.Real-time quantitative PCR and western blotting analyses were performed to confirm the sequencing results and verify the possible mechanisms of ursolic acid-mediated proliferation inhibition in CTCL cells.Results:Ursolic acid exhibited the strongest inhibitory effect on the proliferation of CTCL cells among the six traditional medicine monomers.Transcriptome sequencing analysis showed that 2,466 genes were significantly altered.Combined with Kyoto Encyclopedia of Genes and Genomes functional enrichment analysis and protein-protein interaction network analysis,the interaction of various pathways and signaling molecules,such as tumor necrosis factor-α,NLR family pyrin domain containing 1,c-Jun N-terminal kinase,and melanoma differentiation-associated gene 5,accounted for the anti-tumor effects of ursolic acid in CTCL cells.Conclusion:Ursolic acid significantly inhibited the proliferation of CTCL cells,and our study laid a theoretical foundation for the future treatment of CTCL using ursolic acid.

Retinal Vascular Imaging Application in Women’s Reproductive Health:Clinical Implications and Future Directions

Over the past two decades,population-based studies employing semiautomatic computer-assisted programs have uncovered associations between retinal microvascular features and various systemic conditions.As the recognition of retinal imaging in cardiometabolic health grows,there is increasing evidence supporting its application in women’s health,particularly during the reproductive age.This review aims to summarize the indications of retinal imaging in women’s health and intergenerational health,where suboptimal retinal imaging has been found to mirror pathological systemic changes,such as suboptimal hemodynamic circulation,inflammation,endothelial dysfunction,oxidative stress,and hypoxia in vivo.Findings from Singapore Growing Up in Singapore Towards Healthy Outcomes and Singapore Preconception Study of Long-Term Maternal and Child Outcomes cohorts have reported serial changes in retinal conventional microvascular features(e.g.,retinal arteriolar narrowing,retinal venular widening)and retinal geometric microvascular features(e.g.,sparse fractal dimension,enlarged branching angle,and increased curvature tortuosity)during the preconception and antenatal phases.These morphological abnormalities were found to be related to female fertility,maternal antenatal health conditions,postnatal maternal cardiometabolic health,and intergenerational health in the fetus.Given the compelling evidence of the ability to detect microvascular changes through noninvasive methods at an early stage,retinal imaging holds the potential to facilitate timely interventions,mitigate the progression of complications,and prevent adverse pregnancy outcomes.Looking ahead,the convergence of artificial intelligence and advanced imaging techniques heralds a promising era in women’s health research and clinical practice.

A Li_(3)Bi/LiF interfacial layer enabling highly stable lithium metal anode

Lithium metal anode is considered the alternative to graphite anode due to its ultra-high theoretical capacity of 3860 mAh·g^(-1).However,serious Li dendrite growth and drastic electrolyte side reactions restrain the commercial application of Li metal anode.In this work,a Li_(3)Bi/LiF interfacial layer is constructed on the surface of the Li metal anode by a spontaneous substitution reaction.The composite interfacial layer possesses excellent ionic conductivity,high mechanical strength,and great electrolyte wettability,which ensures fast Li-ion transfer and uniform Li deposition of the Li_(3)Bi/LiF@Li anode.Impressively,the Li_3Bi/LiF@Li symmetric cell provides a cycle life of more than 400 h with only 73 mV voltage polarization at 10 mA·cm^(-2).By pairing with commercial NCM622 cathode,the Li_(3)Bi/LiF@Li full cell exhibits a long cycle at a rate of 2 C.
