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.

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.

Mesenchymal stem cells(MSCs)are multipotent stromal cells that possess the capacity for self-renewal and differentiation into multiple cell lineages.Due to the ease of procurement,robust expansion in vitro,the multipotency,they are recognized as a vital source of stem cells in the field of regenerative medicine.MSCs can be isolated from various tissues,including bone marrow,adipose tissue,and umbilical cord.Research indicates that Human umbilical cord mesenchymal stem cells(hUCMSCs)play an effective role in wound healing and tissue regeneration,and can be utilized for the repair of skin wounds.They are also considered to be the most promising seed cells for skin tissue engineering.This review aims to provide an overview of the biological characteristics of hUCMSCs,the mechanisms in promoting skin wound healing,and their clinical applications.

Objective To investigate the relationship between the expression of serum cartilage intermediate layer protein 1(Cilp1)and myocardial fibrosis(MF)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 106 patients with T2DM(T2DM group)who were admitted to The First Hospital of Qinhuangdao were selected for this study,and 110 healthy individuals were entered into the control group.The serum Cilp1 and MF indexes[procollagen type Ⅲ-N-terminal peptide(P Ⅲ NP),galactose lectin-3(Gal-3),hyaluronic acid(HA),type Ⅲ procollagen(PCⅢ)]were detected and compared between the two groups.According to the degree of MF,there were 31,25,23,and 27 patients with stage 0,1,2,and 3 disease,respectively.The levels of serum Cilp1 and serum Cal-3,P Ⅲ NP,PC Ⅲ,HA were compared between patients of different stages.The Spearman method was applied to analyze the correlation between serum Cilp1 and MF staging,while the Pearson method was applied to analyze the correlation between serum Cilp1 and Gal-3,P Ⅲ NP,PC Ⅲ,HA.We also performed a multivariate logistic regression analysis of the influencing factors of MF 2 to 3 in patients with T2DM,and a receiver operating characteristic(ROC)curve analysis was applied to evaluate the diagnostic efficacy of serum Cilp1 level for MF 2 to 3 in patients with T2DM.Results The serum Cilp1 level in the T2DM group was higher than that in the control group(t=21.758,P＜0.05).Furthermore,the serum levels of Gal-3,P Ⅲ NP,PC Ⅲ,and HA in the T2DM group were higher than those in the control group(t=16.536-27.385,all P＜0.05),and the serum Cilp1 level in patients with T2DM positively correlated with MF staging,Gal-3,PⅢ NP,PC Ⅲ,and HA(r=0.724,0.555,0.501,0.588,0.655,all P＜0.05).The expression level of serum Cilp1 was found to be an influencing factor of MF 2 to 3 in patients with T2DM(P＜0.05).Furthermore,the ROC curve analysis showed that the area under the curve of serum Cilp1 for diagnosing MF stage 2 to 3 in patients with T2DM was 0.914.Conclusion Serum Cilp1 levels are elevated in patients with T2DM,and Cilp1 level closely relates to the formation of MF.This information can assist in clinical judgment of the degree of MF in patients with T2DM.

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.

Venous thromboembolism (VTE) is a complication in children with acute lymphoblastic leukemia (ALL). The Chinese Children's Cancer Group-ALL-2015 protocol was carried out in China, and epidemiology, clinical characteristics, and risk factors associated with VTE were analyzed. We collected data on VTE in a multi-institutional clinical study of 7640 patients with ALL diagnosed in 20 hospitals from January 2015 to December 2019. First, VTE occurred in 159 (2.08%) patients, including 90 (56.6%) during induction therapy and 108 (67.92%) in the upper extremities. T-ALL had a 1.74-fold increased risk of VTE (95% CI 1.08-2.8, P = 0.022). Septicemia, as an adverse event of ALL treatment, can significantly promote the occurrence of VTE (P < 0.001). Catheter-related thrombosis (CRT) accounted for 75.47% (n = 120); and, symptomatic VTE, 58.49% (n = 93), which was more common in patients aged 12-18 years (P = 0.023), non-CRT patients (P < 0.001), or patients with cerebral thrombosis (P < 0.001). Of the patients with VTE treated with anticoagulation therapy (n = 147), 4.08% (n = 6) had bleeding. The VTE recurrence rate was 5.03% (n = 8). Patients with VTE treated by non-ultrasound-guided venous cannulation (P = 0.02), with residual thrombus (P = 0.006), or with short anticoagulation period (P = 0.026) had high recurrence rates. Thus, preventing repeated venous puncture and appropriately prolonged anticoagulation time can reduce the risk of VTE recurrence.
