In recent years， repetitive transcranial magnetic stimulation （rTMS） has garnered significant attention as a therapeutic approach for sleep disorders in the elderly. However， the prevailing rTMS protocols are predominantly developed based on normative neurophysiological data derived from young adults and fail to incorporate individualized parameters tailored to the brain characteristics of the elderly. To address this gap， the consensus development group synthesized the latest evidence from 2010 to 2025 and established a standardized rTMS protocol specifically for elderly patients with sleep disorders. Adhering to the Appraisal of Guidelines for Research and Evaluation II （AGREE II） framework， systematically screened randomized controlled trials （RCTs） and systematic reviews regarding rTMS in the treatment of sleep disorders across various conditions. Meanwhile， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system was employed to rigorously grade the quality of evidence and the strength of recommendations. This consensus guideline delineates precise rTMS protocols for the management of sleep disorders in the elderly， highlights the adjustment of stimulation intensity according to scalp-cortex distance recommends either MRI‑guided neuronavigation or the Beam F3/F4 heuristic approach for accurate target localization， thereby providing precise rTMS intervention protocol for sleep disorders in the elderly， aiming to enhance clinical efficacy while ensuring treatment safety. ［Funded by National Key Research and Development Program （number， 2023YFC3603200）； General Program of Shenzhen Science and Technology Innovation Commission （number， JCYJ20240813112859008， JCYJ20240813112900002）； Youth Program of Shenzhen Kangning Hospital （number， KN2023A004）； www.guidelines-registry.cn number， PREPARE-2026CN530］

Bladder tumor is a common tumor in the urinary system, posing a serious threat to patients’ health and quality of life. The standard surgical method for non-muscle-invasive bladder cancer is the transurethral resection of bladder tumor. As a new type of minimally invasive treatment, transurethral holmium laser has shown unique advantages in the treatment of bladder tumors. This work introduces the epidemiological characteristics of bladder tumors and the limitations of traditional treatment methods and elaborates on the technical principles, development history of holmium laser and its application status in the treatment of bladder tumors. By analyzing clinical research data, it compares therapeutic effects between holmium laser and other treatment methods. It also presents the key points of surgical techniques, perioperative management strategies, and measures for the prevention and treatment of complications. This research discusses the current technical challenges and future development directions in holmium laser treatment, providing references for clinical practice and research.

Background: and Purpose Bilirubin has potent antioxidant, anti-inflammatory, and neuroprotective effects. Herein, we investigated whether total bilirubin (TBIL) modifies the association between hypertension and cerebral small vessel disease (CSVD). Methods: Data were obtained from the PolyvasculaR Evaluation for Cognitive Impairment and vaScular Events study. TBIL and direct bilirubin (DBIL) levels were assayed using fasting venous blood samples. Indirect bilirubin (IBIL) was calculated by subtracting DBIL from TBIL. TBIL was stratified as ≤17 μmol/L and >17 μmol/L based on the biological relevance of Gilbert’s syndrome. Hypertension was defined as blood pressure ≥140/90 mm Hg, self-reported hypertension history, or current use of antihypertensive agents. White matter hyperintensity, lacunes, cerebral microbleeds, and enlarged perivascular spaces were evaluated using magnetic resonance imaging and used to rate CSVD burden according to the criteria proposed by Wardlaw et al. and Rothwell et al. Results: This study included 3,061 participants, with a mean age of 61.2±6.7 years and 46.5% males. After adjusting for confounders, hypertension was associated with increased odds of presence of CSVD (Wardlaw: odds ratio [OR]=1.86, 95% confidence interval [CI] 1.41–2.44, P<0.001; Rothwell: OR=1.84, 95% CI 1.43–2.38, P<0.001) and higher modified total CSVD burden (common OR: 1.85, 95% CI 1.45–2.36, P<0.001) in participants with TBIL ≤17 μmol/L but not in TBIL >17 μmol/L (P for interaction <0.05). Johnson–Neyman analyses showed cut-off concentrations of 22.3–22.4 μmol/L for effect modification by TBIL. IBIL contributed to effect modification, whereas DBIL did not. Conclusions Mildly elevated TBIL may modify the association between hypertension and CSVD.

Background/Aims: Cholangiocarcinoma (CCA) is a primary malignant neoplasm with an extremely poor prognosis. While combined chemoradiotherapy has been demonstrated to delay CCA progression to a certain extent, the absence of specific molecular biomarkers or targets significantly hinders the diagnosis and treatment of CCA. Methods: Through cross-analysis of proteomics and ADMA modificationomics, we identified DDX1 overexpressed in CCA with elevated R602-ADMA modifications. HPLC-MS/MS identified PRMT1 as the methyltransferase and USP10 as the deubiquitinating enzyme for DDX1. Immunofluorescence and nuclear-cytoplasmic partitioning experiments confirmed DDX1’s nuclear localization. GO and KEGG analyses clarify the biological functions of DDX1 in response to hypoxia. RNA-seq transcriptomics analyzed key pathways influenced by DDX1. A hydrodynamic in situ CCA mouse model was established to validate the chemopreventive effects of the PRMT1-specific inhibitor GSK715 on CCA development. Results: DDX1 promotes CCA progression both in vivo and in vitro and can be inhibited by GSK715. Mechanistically, PRMT1 mediates ADMA modification at position R602 of DDX1. This modification promotes DDX1 nuclear localization by recruiting USP10 to deubiquitinate DDX1, while simultaneously inhibiting PRMT1 degradation. DDX1 promotes the transcription of PRMT1 and USP10 by binding to the mRNA 3’UTR region, establishing a positive feedback regulatory pathway. This mechanism promotes the occurrence and development of CCA and can serve as a target for the inhibitor GSK715 to suppress CCA progression. Conclusions Our study identified DDX1-R602-ADMA modification as a novel ADMA modification in CCA. It further confirmed its pivotal role in CCA progression. Targeting the USP10-PRMT1-DDX1 axis may represent a significant therapeutic approach for CCA.

Objective:To investigate the risk factors and their diagnostic efficacy of perioperative lower limb deep vein thrombosis (DVT) in polytrauma patients with predominant severe limb trauma.Methods:A retrospective cohort study was conducted to analyze the clinical data of 155 polytrauma patients with predominant severe trauma who were admitted to Wuxi Ninth People′s Hospital from January 2021 to December 2024, including 64 males and 91 females, aged 13-95 years [(52.1±16.9)years]. Abbreviated injury scale (AIS) was 5-15 points [(7.4±2.1)points] and injury severity score (ISS) was 17-59 points [(21.3±6.5)points]. Based on the occurrence of DVT in the perioperative period, the patients were divided into preoperative DVT group with 17 patients (11.0%) and non-preoperative DVT group with 138 patients (89.0%) as well as postoperative DVT group with 24 patients (15.5%) and non-postoperative DVT group with 131 patients (84.5%). Basic clinical data were collected, including gender, age, body mass index (BMI), underlying diseases (hypertension, diabetes mellitus), hemoglobin level (Hb), platelet count (PLT), D-dimer, ISS, trauma site [cranial and brain trauma, thoracic and abdominal trauma, upper limb trauma, lower limb trauma (femoral fracture, patellar fracture, tibial or fibular fracture, foot fracture, vascular injury), and pelvic fracture], preoperative waiting time for surgery, surgical site (pelvis and lower limb, other areas), surgical protocols (pelvic and lower limb internal fixation, external fixation of lower limb, lower limb amputation), operation duration less or more than 2 hours, amount of intraoperative blood loss, intraoperative blood transfusion requirement, venous thromboembolism (VTE) prophylaxis (pharmacological and mechanical modalities) and length of hospital stay. Univariate analysis and multivariate binary Logistic regression analysis were conducted to investigate the correlation between the aforementioned indicators and incidence of perioperative lower limb DVT in polytrauma patients with predominant severe limb trauma and determine the independent risk factors. Receiver operating characteristic (ROC) curve and area under the curve (AUC) of the relevant risk factors were analyzed to evaluate and compare the diagnostic efficacy of the risk factors for perioperative lower limb DVT in polytrauma patients with predominant severe limb trauma.Results:Univariate analysis results showed that age, history of hypertension, D-dimer, thoracic and abdominal trauma, pelvic fracture, preoperative waiting time for surgery, and length of hospital stay were significantly correlated with preoperative of DVT of the lower limbs in the patients ( P<0.05). The results of multivariate binary Logistic regression analysis showed that age ( OR=1.05, 95% CI 1.00, 1.10, P<0.05), pelvic fracture ( OR=5.03, 95% CI 1.09, 23.20, P<0.05), preoperative waiting time for surgery ( OR=1.10, 95% CI 1.00, 1.22, P<0.05) and length of hospital stay ( OR=0.89,95% CI 0.81,0.98, P<0.05) were highly correlated with preoperative DVT of the lower limbs in the patients ( P<0.05). Univariate analysis results showed that age, D-dimer, ISS, foot fracture, and length of hospital stay were significantly correlated with postoperative DVT of the lower limbs in the patients ( P<0.05). The results of multivariate binary Logistic regression analysis showed that age ( OR=1.05, 95% CI 1.01, 1.08, P<0.01), D-dimer ( OR=1.05, 95% CI 1.00, 1.10, P<0.05), ISS ( OR=1.09, 95% CI 1.01, 1.17, P<0.05), and foot fracture ( OR=3.51 , 95% CI 1.25 , 9.87 , P<0.05) were significantly correlated with postoperative DVT of the lower limbs in the patients ( P<0.05). The results of the ROC curve analysis indicated that preoperative waiting time for surgery (AUC=0.83, 95% CI 0.75, 0.91) had the highest diagnostic efficacy for preoperative DVT of the lower limbs in the patients, with the diagnostic efficacies of pelvic fracture (AUC=0.75, 95% CI 0.65, 0.85) and age (AUC=0.70, 95% CI 0.59, 0.82) decreasing successively. For postoperative DVT of the lower limbs in the patients, D-dimer (AUC=0.71, 95% CI 0.61, 0.81) exhibited the highest diagnostic efficacy, followed by age (AUC=0.70, 95% CI 0.59, 0.81), ISS (AUC=0.64, 95% CI 0.51, 0.76) and foot fracture (AUC=0.62, 95% CI 0.49, 0.74), with diagnostic efficacy decreased successively. Conclusions:For polytrauma patients with predominant severe limb trauma, age, pelvic fracture and preoperative waiting time for surgery are independent risk factors for preoperative DVT, while age, D-dimer, ISS and foot fracture are independent risk factors for postoperative DVT. Additionally, preoperative waiting time for surgery has the best diagnostic efficacy for preoperative DVT, followed by pelvic fracture and age. D-dimer has the best diagnostic efficacy for postoperative DVT, followed by age, ISS and foot fracture.

BACKGROUND:In vitro reconstruction of hair follicles depends on the self-assembly behavior of dermal papilla cells and keratinocytes during three dimensional co-culture,which is very similar to the development of hair follicle embryos.Therefore,hair follicle organoids can be used as a good model in vitro for basic research of hair follicle regeneration.Currently,wholly humanized follicle organoids cultured by biomimetic system have been successfully transplanted into animals.Research on hair follicle organoids makes it possible to regenerate hair follicles,but there is no uniform conclusion on the construction method,and there are still many challenges.OBJECTIVE:To review the current research progress of hair follicle organoids,summarize their culture methods and characterization,and expound their application prospects,so as to provide reliable basis for subsequent research,in order to promote its clinical transformation in tissue engineering and alopecia treatment.METHODS:CNKI and PubMed databases were searched by a computer,using"hair follicle regeneration,hair regeneration,organoid"as Chinese search terms and"hair growth,hair loss,hair regeneration,hair follicle,dermal papilla cell,organoid"as English search terms.The domestic and foreign literature on hair follicle organoids was reviewed and a total of 67 articles were included for follow-up analysis.RESULTS AND CONCLUSION:(1)Dermal papilla cells and keratinocytes from different sources can be used to construct hair follicle organoids in vitro to obtain mouse-derived,human-mouse chimeric and human-derived hair follicle organoids,which have been successfully used in rodent transplantation models.(2)A variety of programming methods,such as electrical stimulation,addition of recombinant protein,and dissociation of cell gene expression,can be used to promote hair follicle organoid such ashair follicle germ formation and hair shaft elongation.Simultaneously,the application of various 3D printing technologies has achieved controllable hair follicle organoid to the size of the quantity production,which greatly improves the production efficiency.(3)When melanocytes are added to the dissociated cell co-culture system,the problem of pigment deficiency in new hair follicles may be solved.When human umbilical vein endothelial cells are added,the new blood vessels in the cell aggregates can improve their nutrient supply and reduce necrosis in the central area.(4)As the technology of engineered hair follicle organoid gradually maturates,hair follicle organoids constructed from patient's autologous cells may be used for individualized treatment of severe alopecia.

BACKGROUND:The blood-brain barrier is an important structure that protects the central nervous system,and the study of the effects of high glucose on the blood-brain barrier is important for the prevention of high glucose-induced damage to the central nervous system.OBJECTIVE:To investigate the potential effect of high glucose on the blood-brain barrier function of hCMEC/D3 human brain microvascular endothelial cells.METHODS:hCMEC/D3 cells were cultured in regular sugar medium(glucose concentration of 25 mmol/L)and high-sugar medium(glucose concentration of 55 mmol/L).The morphology of cells in each group was observed by light microscopy.CCK-8 assay was used to detect changes in cell viability.A monolayer blood-brain barrier model was established using hCMEC/D3 cell line with Transwell chamber device.Changes in cell transmembrane resistance were monitored daily.The permeability of cell monolayers was detected by phenol red permeability.Flow cytometry was used to detect the apoptosis rate of the cells.Western blot assay was used to detect the expression of Bcl-2,Bax,Caspase-3,ZO-1,Occludin,Claudin-1,and histone deacetylase 4.The levels of histone deacetylase in cell supernatant were detected by ELISA.The expression of histone deacetylase 4 in cells was detected by immunofluorescence.RESULTS AND CONCLUSION:(1)The cell viability of high sugar group was significantly lower than that of control group(P＜0.000 1).(2)The cells of the control group were in a good growth state,interwoven into a dense mesh,with interconnections between synapses.The cell growth of high glucose group was suppressed,and the connection of inter-cellular synapses was reduced.(3)Compared with the control group,the transmembrane resistance value of the high glucose group was reduced(P＜0.05);phenol-red permeability of the monolayer cell membrane was increased(P＜0.05);cell apoptosis rate was increased(P＜0.01);the expression of Bax protein was increased(P＜0.000 1);the expression of Caspase-3 protein had no significant change(P＞0.05);the expression of Bcl-2,ZO-1,Occludin,Claudin-1,and histone deacetylase 4 proteins was decreased(P＜0.01,P＜0.001,P＜0.01,P＜0.000 1,P＜0.01);the fluorescence expression of histone deacetylase 4 was decreased(P＜0.001)in the high glucose group.(4)The level of histone deacetylase 4 in the cell supernatant of the high glucose group was lower than that of the control group(P＜0.05).The results show that high glucose induces the increased apoptosis and enhances permeability of hCEMCE/D3 cells,and its mechanism may be related to the decreased expression level of histone deacetylase 4.

Objective To explore the feasibility of treating recurrent mandibular neuralgia with radiofrequency thermocoagulation with double needle guide,and to study the clinical value of double needle puncture for foramen ovale.Methods In this study,40 patients with recurrent mandibular neuralgia admitted to our hospital from January 2018 to November 2023 were selected,and randomly divided into the observation group(20 cases using double-needle guide technology)and control group(20 cases using traditional single-needle guide technology).The two groups were compared before and after treatment.Results After the completion of radiofrequency thermo-coagulation therapy,the overall pain-free rate of all cases was 90％according to the adjusted grading criteria,and there was a differ-ence in the pain-free rate between the two groups(P＜0.05).There was no significant difference in the number of puncture adjustment and complications between the two groups(P＞0.05).The operation time of the observation group was longer than that of the control group(P＜0.05),and the number of postoperative acupuncture pain cases was statistically different from that of the control group(P＜0.05).After comparison of facial visual analogue scale(F-VAS),it was found that there were significant differences between the two groups(P＜0.05),and there were statistical differences between the observation group and the control group(P＜0.05).Conclusion Radiofrequency thermocoagulation with double-channel technique treating patients with recurrent mandibular neuralgia is,more thorough and has less complications.Although the operation time is increased,it can effectively eliminate the pain of patients.The tra-ditional bipolar radiofrequency thermocoagulation therapy technology is easily and accurately accomplished,which is worth popularizing.
