Ursodeoxycholic acid(UDCA)is a naturally occurring,low-toxicity,and hydrophilic bile acid(BA)in the human body that is converted by intestinal flora using primary BA.Solute carrier family 7 member 11(SLC7A11)functions to uptake extracellular cystine in exchange for glutamate,and is highly expressed in a variety of human cancers.Retroperitoneal liposarcoma(RLPS)refers to liposarcoma originating from the retroperitoneal area.Lipidomics analysis revealed that UDCA was one of the most significantly down-regulated metabolites in sera of RIPS patients compared with healthy subjects.The augmentation of UDCA concentration(≥25 μg/mL)demonstrated a suppressive effect on the proliferation of liposarcoma cells.[15N2]-cystine and[13Cs]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione(GSH)synthesis.Mechanistically,UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis,leading to reactive oxygen species(ROS)accumulation and mitochondrial oxidative damage.Furthermore,UDCA can promote the anti-cancer effects of ferroptosis inducers(Erastin,RSL3),the murine double minute 2(MDM2)inhibitors(Nutlin 3a,RG7112),cyclin dependent kinase 4(CDK4)inhibitor(Abemaciclib),and glutaminase inhibitor(CB839).Together,UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity,and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA.More importantly,in combination with other antitumor chemotherapy or physiotherapy treatments,UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [¹⁵N₂]-cystine and [¹³C₅]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Objective To observe the clinical efficacy of Dulongneedling in the treatment of vertigo in cervical spondylosis of vertebral artery(CSA).Methods A total of 46 cases of patients with definitive diagnosis of vertigo in CSA admitted to the outpatient clinic of the Acupuncture,Muxibustion and Rehabilitation Department of Guangdong Second Traditional Chinese Medicine Hospital from June to October 2024 were selected for the study.The patients were randomly divided into observation group and control group according to the random number table method,with 23 cases in each group.The observation group was treated with Dulongten-needling in shoulder and neck,and the control group was given conventional acupuncture treatment,the course of treatment for the two groups covered two weeks.After two weeks of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the scores of Evaluation Scale For Cervical Vertigo(ESCV)before and after treatment were observed in the patients of the two groups.Three dimensional pseudo-continuous arterial spin labeling(3D-pCASL)technique was applied to determin the changes in cerebral blood flow(CBF)values in the region of region of interest(ROI),and the changes in CBF values in the patients of the two groups were compared.Results(1)The total effective rate of the observation group was 91.30%(21/23),and that of the control group was 78.26%(18/23),and the efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P<0.05).(2)After treatment,the ESCV scores of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(3)After treatment,the CBF change values of each ROI in the two groups showed elevated(positive),and the CBF change values of the right middle cerebral artery(R-MCA)in the control group showed decreased(negative).After treatment,the CBF change values of the observation group in the blood supply areas of the right posterior inferior cerebellar artery(R-PICA),right anterior inferior cerebellar artery(R-AICA),right anterior cerebral artery(R-ACA),branches from vertebral arteries(VA)and basilar arteries(BA),bilateral superior cerebellar arteries(SCA),and bilateral posterior cerebral arteries(PCA)were significantly elevated,and the observation group was significantly superior in improving the above ROIs in the CBF change value to that of the control group,the difference being statistically significant(P<0.05).Conclusion Dulongneedling in the treatment of vertigo in CSA can significantly improve the CBF of patients,reduce the clinical symptoms such as vertigo,neck and shoulder pain,headache.

Cerebral hemorrhage accounts for about 10%-15% of all strokes， and its pathogenesis is complex. Currently， the main clinical treatment is mainly medical symptomatic treatment， including the use of antihypertensive drugs， hypoglycemic drugs， and hemostatic drugs， and surgical treatment is required in some cases， but there is still a lack of effective treatment. In recent years， traditional Chinese medicine and proprietary Chinese medicine have been widely accepted for their stable efficacy， high safety， and low cost. Rhei Radix et Rhizoma is one of the most commonly used herbal medicines for the treatment of cerebral hemorrhage. This paper summarizes the relevant literature on the treatment of cerebral hemorrhage with Rhei Radix et Rhizoma and finds that its active ingredients are mainly anthraquinones， such as emodin， Rhei Radix et Rhizoma acid， and Rhei Radix et Rhizoma phenol. The herbal formulas are Da Chengqitang， Shengdi Dahuangtang， Liangxue Tongyufang， and Naoxueshu oral liquid. The effects involve protecting the blood-brain barrier， promoting hematoma absorption， reducing inflammation levels， decreasing lactic acid accumulation at the bleeding site， and increasing the expression of brain-derived neurotrophic factors. The pathways involved include aquaporin 4 （AQP4）， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， extracellular signal-regulated kinase 1/2 （ERK1/2）， Toll-like receptor 4 （TLR4）， nuclear transcription factor-κB （NF-κB）， nuclear factor E₂-related factor 2 （Nrf2）， and Wnt3a/β-linked protein pathway. This paper summarizes the progress of clinical studies and animal experiments on the treatment of cerebral hemorrhage with active ingredients of Rhei Radix et Rhizoma and herbal compounds containing Rhei Radix et Rhizoma， so as to provide a reference for the treatment protocol of cerebral hemorrhage.
