Objective To explore the relationship between triglyceride-glucose index(TyG)and acute ischemic stroke with large vessel occlusion(AIS-LVO)of anterior circulation.Methods A retrospective study was conducted on patients with anterior circulation AIS-LVO who underwent emergency endovascular thrombectomy at Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2019.According to modified Rankin scale(mRS)score 90 d after operation,the patients were assigned to favorable outcome group(mRS score 0-2)or unfavorable outcome group(mRS score 3-6),and the TyG was compared.According to the median of TyG,the patients were assigned to low-TyG group(TyG＜8.57)or high-TyG group(TyG ≥8.57),and the clinical data,laboratory indexes,and imaging characteristics were compared.Receiver operating characteristic curve was used to evaluate the predictive value of TyG for poor prognosis.Results A total of 135 patients were enrolled,with 72 in the favorable outcome group and 63 in the unfavorable outcome group.The TyG of the unfavorable outcome group was significantly higher than that of the favorable outcome group(8.82+0.63 vs 8.43+0.60,P＜0.001).There were 67 patients in the low-TyG group and 68 in the high-TyG group.Compared with the low-TyG group,the proportion of patients with hyperlipidemia history(P=0.003),systolic blood pressure at admission(P=0.018),fasting blood glucose level(P＜0.001),and triglyceride level(P＜0.001)were significantly higher in the high-TyG group,the infarct core volume was significantly larger(P=0.025),the high density lipoprotein-cholesterol level was significantly lower(P=0.013),and the mRS score 90 d after operation was significantly higher(3[1,5]vs 1[0,5],P=0.049).The TyG had certain predictive value for poor prognosis in anterior circulation AIS-LVO patients(area under curve value=0.662,95％confidence interval 0.571-0.753).Conclusion TyG is elevated in anterior circulation AIS-LVO patients with poor prognosis,and may be a potential prognostic indicator for anterior circulation AIS-LVO patients.

Peptide receptor radionuclide therapy (PRRT) with radiolabeled SSTR2 agonists is a treatment option that is highly effective in controlling metastatic and progressive neuroendocrine tumors (NETs). Previous studies have shown that an SSTR2 agonist combined with albumin binding moiety Evans blue (denoted as ¹⁷⁷Lu-EB-TATE) is characterized by a higher tumor uptake and residence time in preclinical models and in patients with metastatic NETs. This study aimed to enhance the in vivo stability, pharmacokinetics, and pharmacodynamics of ¹⁷⁷Lu-EB-TATE by replacing the maleimide-thiol group with a polyethylene glycol chain, resulting in a novel EB conjugated SSTR2-targeting radiopharmaceutical, ¹⁷⁷Lu-LNC1010, for PRRT. In preclinical studies, ¹⁷⁷Lu-LNC1010 exhibited good stability and SSTR2-binding affinity in AR42J tumor cells and enhanced uptake and prolonged retention in AR42J tumor xenografts. Thereafter, we presented the first-in-human dose escalation study of ¹⁷⁷Lu-LNC1010 in patients with advanced/metastatic NETs. ¹⁷⁷Lu-LNC1010 was well-tolerated by all patients, with minor adverse effects, and exhibited significant uptake and prolonged retention in tumor lesions, with higher tumor radiation doses than those of ¹⁷⁷Lu-EB-TATE. Preliminary PRRT efficacy results showed an 83% disease control rate and a 42% overall response rate after two ¹⁷⁷Lu-LNC1010 treatment cycles. These encouraging findings warrant further investigations through multicenter, prospective, and randomized controlled trials.

Lophatheri Herba (Danzhuye in Chinese) is derived from the dried stems and leaves of Lophatherum gracile and has a long history of use as a medicinal and food source. Flavonoids and phenolic acids are the main active ingredients in Lophatheri Herba, which produce diuretic, anti-inflammatory, and antipyretic effects. Flavonoid glycosides and hydroxybenzoic acids are respectively the main structure in 44 flavonoids and 16 phenolic acids obtained from Lophatheri Herba. Modern pharmacological studies have found that the main chemical constituents of Lophatheri Herba play important roles in anti-inflammatory, cardioprotective, hepatoprotective and hypoglycaemic effects. Studies have demonstrated that flavonoid monomers, for example, luteolin, isoorientin, luteolin-7-O-β-D-glucoside and apigenin are more effective in exerting the above pharmacological effects. In addition, Lophatheri Herba is used in different food products as the main ingredient or as an accessory. This review describes Lophatheri Herba in terms of its chemical composition, pharmacological effects and efficacy, food development and applications, and clinical utility, and discusses the problems facing its use. This study provides valuable ideas and a scientific basis for the future development and use of L. gracile.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

ObjectiveThis study aims to observe the effect of sinomenine （SIN） on fatty acid binding protein 4 （FABP4） in synovial tissue of rats with osteoarthritis （OA） and investigate the therapeutic mechanism of SIN on OA， further providing new ideas for the management of osteoarthritis by traditional Chinese medicine （TCM）. MethodsAn OA rat model was constructed and randomly divided into a control group， an OA group， an OA + SIN-L group （50 mg·kg^-1）， an OA + SIN-M （100 mg·kg^-1）， an OA + SIN-H （200 mg·kg^-1）， and an OA + prednisone （PDN） group （5 mg·kg^-1）. Following surgical modeling for three weeks， an appropriate medication was administered for four weeks. During modeling and administration， a hot plate test was performed to detect the pain and swelling of the knee joints of the rats. The periarticular tissue was collected for arthropathological observation at the end of drug administration. The expression of cleaved Caspase-3， B-cell lymphoma-2 （Bcl-2）， Bcl-2 associated X protein （Bax）， and FABP4 in the synovial tissue of rats was detected by Western blot and real-time quantitative polymerase chain reaction （Real-time PCR）， and the expression and distribution of FABP4 protein in the synovial membrane were detected by immunofluorescence. ResultsCompared with those in the control group， the levels of inflammatory factors and FABP4 in the serum of rats in the OA group were significantly increased （P<0.05， P<0.01）， and joint swelling was significantly elevated （P<0.01）. The thermal pain threshold was significantly reduced （P<0.01）， and the expression of FABP4 protein and the fluorescence intensity were significantly increased （P<0.01）. The synovial tissue exhibited significantly increased inflammatory infiltration， proliferated fibroblasts， and an elevated apoptotic index （P<0.05， P<0.01）. Compared with those in the OA group， the serum lipid metabolism indexes of rats in the SIN administration group gradually returned to normal （P<0.05， P<0.01）， while the levels of inflammatory factors and FABP4 in the serum of rats in the SIN-administered group were significantly reduced （P<0.05， P<0.01）， and joint swelling was significantly decreased （P<0.05， P<0.01）. The thermal pain threshold was significantly elevated （P<0.05， P<0.01）， and the expression of FABP4 protein and fluorescence intensity in the synovial tissue were significantly decreased （P<0.05， P<0.01）. The synovial tissue displayed significantly reduced inflammatory infiltration and a decreased apoptotic index （P<0.05， P<0.01）. ConclusionThe therapeutic effect of SIN on OA may be related to the down-regulation of FABP4 expression， reduction of apoptosis， and inhibition of inflammatory factor expression.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To comapre and analyze the differences and commonalities of expression profiles of serum exosomal microRNA between patients with thyroid nodules and healthy persons at different iodine levels,and then provide evidence for screening early diag-nostic markers of thyroid nodules at different iodine levels.Methods The peripheral blood samples from 10 patients with thyroid nod-ules and healthy volunteers at different iodine levels were collected.Their serum iodine levels were measured by the arsenic cerium cat-alytic spectrophotometry.Serum exosomal microRNA were extracted and the expression levels of microRNA were determined by the high-throughput sequencing technology.The differential target genes were predicted and further performed Gene ontology(GO)analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis.Results Compared with healthy volunteers,there were 6 downreg-ulated miRNAs in the patients with thyroid nodules at different iodine levels,namely miR-324-5p,miR-6511b-3p,miR-9903,miR-550a-3p,miR-5001-3p,and miR-3688-3p.Differentially expressed exosomal microRNA could regulate the MAPK signaling path-way,PI3K-AKT signaling pathway,VEGF signaling pathway,and NF-κB signaling pathway.Conclusion Six differentially expressed microRNAs is identified,which may serve as biological markers for the early diagnosis of thyroid nodules at different iodine levels.
