Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Ovarian tumor (OT) is the most lethal form of gynecologic malignancy, with minimal improvements in patient outcomes over the past several decades. Metastasis is the leading cause of ovarian cancer-related deaths, yet the underlying mechanisms remain poorly understood. Psychological stress is known to activate the glucocorticoid receptor (NR3C1), a factor associated with poor prognosis in OT patients. However, the precise mechanisms linking NR3C1 signaling and metastasis have yet to be fully elucidated. In this study, we demonstrate that chronic restraint stress accelerates epithelial-mesenchymal transition (EMT) and metastasis in OT through an NR3C1-dependent mechanism involving nuclear protein 1 (NUPR1). Mechanistically, NR3C1 directly regulates the transcription of NUPR1, which in turn increases the expression of snail family transcriptional repressor 2 (SNAI2), a key driver of EMT. Clinically, elevated NR3C1 positively correlates with NUPR1 expression in OT patients, and both are positively associated with poorer prognosis. Overall, our study identified the NR3C1/NUPR1 axis as a critical regulatory pathway in psychological stress-induced OT metastasis, suggesting a potential therapeutic target for intervention in OT metastasis.

Objective:To investigate the predictive value of serum neutrophil gelatinase-associated lipocalin(NGAL),calcitonin gene-related peptide(CGRP),and neutrophil-to-lymphocyte ratio(NLR)for the prognostic regression of elderly patients with stroke complicated with pulmonary infection(SCPI).Methods:This study was a retrospective single-center study,149 elderly patients with SCPI who were admitted to Inner Mongolia Baogang Hospital from June 2020 to June 2024 were selected,they were divided into poor prognosis group(n=56)and good prognosis group(n=93)according to the prognosis.Baseline data and laboratory test indicators were collected,and NLR was calculated.Serum NGAL and CGRP levels were measured by ELISA.Influencing factors of poor prognosis of elderly patients with SCPI were analyzed by Multivariate logistic regression.Predicts value was analyzed by Receiver operating characteristic(ROC)curve.Results:Compared with good prognosis group,the poor prognosis group had higher of aged ≥ 70 years,incidence of hemorrhagic stroke,serum creatinine,white blood cell count,national institute of health stroke scale(NIHSS),platelet count,C-reactive protein,NGAL,and NLR levels,longer nerosurgery intensive care unit(NICU)stay,and lower CGRP levels(P＜0.05).Higher CGRP level was an independent protective factor of poor prognosis of elderly patients with SCPI(OR＜1,P＜0.05).Age ≥ 70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR were independent risk factors of poor prognosis of elderly patients with SCPI(OR＞1,P＜0.05).The area under the curve(AUC)for predicting the prognostic regression of elderly patients with SCPI used NGAL,CGRP,and NLR alone or in combination was 0.777,0.771,0.786,and 0.927,respectively,with the combination of three factors showed the highest predictive power(P＜0.05).Conclusion:Age ≥70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR are independent risk factors of poor prognosis of elderly patients with SCPI,while higher CGRP level is an independent protective factor.The combination detection of NGAL,CGRP and NLR can improve the predictive value of prognostic regression in elderly patients with SCPI.

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Objective:To investigate the expression, distribution and cellular localization of acylglycerol kinase (AGK) in liver cancer tissues, and the correlation of AGK expression with the prognosis of liver cancer patients.Methods:AGK mRNA expression data and clinical information of hepatocellular carcinoma (HCC) patients were downloaded from The Cancer Genome Atlas (TCGA) database in January 2024. The expression differences of AGK mRNA between HCC tissues and paracancerous tissues were compared, and the high and low expressions of AGK were judged by using the median expression of AGK mRNA in 369 HCC tissues as a cut-off value. A univariate logistic regression model was used to analyze the relationship between clinical pathological characteristics and high expression of AGK. The mRNA expressions in HCC tissues and paracancerous tissues of 9 datasets from the Hepatocellular Carcinoma Molecular Landscape Database (HCCDB) 2.0 were compared. The spatial distribution and cellular localization of AGK were analyzed based on multidimensional data from Bulk transcriptome sequencing (RNA-seq), single-cell sequencing and spatial RNA-seq. The expression of AGK protein in liver cancer tissues was analyzed using the Human Protein Atlas (HPA) database. Kaplan-Meier method and log-rank test were employed to compare the differences in overall survival (OS) among patients with different AGK mRNA expressions in HCCDB25 dataset of HCCDB 2.0 and HPA database. The correlation between expressions of AGK and hepatic stem cell-related markers was analyzed by using Spearman rank test based on Tumor Immune Estimation Resource (TIMER) 2.0 database.Results:Data from both the TCGA and 9 datasets of HCCDB 2.0 showed that AGK mRNA expression in HCC tissues was higher than that in paracancerous non-tumorous tissues and normal liver tissues, and the difference was statistically significant (all P < 0.001). HPA database immunohistochemical testing revealed that AGK protein was primarily localized in the cytoplasm, with positive or strong positive expression in HCC tissues and negative or weak positive expression in normal liver tissues; mass spectrometry data showed that it was upregulated in tumor samples (165 cases) compared to normal liver tissues (165 cases) ( P < 0.001). Univariate logistic regression analysis indicated that tumor family history and tumor pathological differentiation in HCC patients from TCGA database were associated with high AGK expression in tumor tissues ( P values were 0.028 and 0.050), while other factors such as age, gender, body mass index, alpha fetoprotein level, Child-Pugh classification, inflammation degree in paracancerous tissues, Ishak fibrosis score, pathological TNM staging, tumor clinical staging, and tumor vascular infiltration had no impact on AGK expression level in tumor tissues (all P > 0.05). One hundred and fifty-eight patients were divided into high and low KGK mRNA expression groups based on the median expression of AGK mRNA in tissues of HCCDB25 dataset, analysis showed that patients in low AGK mRNA expression group (79 cases) had better overall survival (OS) compared to the high expression group (79 cases) in tumor tissues, and the difference was statistically significant ( P = 0.038), while there was no significant difference in OS between high (79 cases) and low (79 cases) expression groups in paracancerous tissues ( P = 0.760). In HPA database, patients were divided into high and low AGK mRNA expression groups based on AGK mRNA values in liver cancer tissues corresponding to the lowest P value during OS analysis by Kaplan-Meier method; in all stages of HCC patients, low AGK mRNA expression group (279 cases) had better OS than the high expression group (76 cases), and the difference was statistically significant ( P = 0.022). The OS of high AGK mRNA expression group in patients with stages Ⅱ-Ⅲ was worse than that of low expression group, and the difference was statistically significant ( P = 0.007). The UMAP plot obtained through dimensionality reduction and cell clustering analysis based on single-cell sequencing data in HCCDB 2.0 revealed that AGK gene expression in liver cancer tissues was primarily distributed in tumor cells, NK/T cells, stromal cells, and myeloid cells. Spatial transcriptomic analysis of tissue samples from 5 HCC patients using HCCDB 2.0 online tools showed that AGK expression varied across different liver cancer tissue regions (non-tumorous tissue, paracancerous tissue, tumor junction, tumor focus, and portal vein tumor thrombus), with 3 cases showing AGK expression enrichment in tumor cells of the tumor junction, tumor focus and portal vein tumor thrombus, while lower in normal hepatocytes, stromal cells and immune cells. In 2 cases, AGK expression was more widespread. Analysis of 3 patients with significant AGK enrichment showed that in HCC samples with complete fibrous capsule, AGK was mainly localized in tumor cells of the tumor focus and junction areas, with weaker expression in paracancerous normal tissues; while in samples with incomplete capsule, high AGK expression was primarily in tumor cells of the tumor junction, tumor focus and portal vein tumor thrombus. TIMER 2.0 database assessment showed that AGK gene expression in 371 patients of TCGA database was positively correlated with the expressions of liver cancer stem cell-related marker genes, including PROM1 ( rho = 0.250), TYH1 ( rho = 0.188), CD44 ( rho = 0.268), ANPEP ( rho = 0.171), CD47 ( rho = 0.435), EPCAM ( rho = 0.246), KRT19 ( rho = 0.203), TGFB1 ( rho = 0.285), and SOX9 ( rho = 0.328) (all P < 0.001). Conclusions:AGK expression is significantly upregulated at both mRNA and protein levels in tumor tissues of HCC patients, it predominantly localizes in the tumor tissues and the cytoplasm of tumor cells within the junction areas, and its high expression closely associates with poor prognosis of patients. Its expression is positively correlated with the expression of liver cancer stem cell-related markers.

Objective:To evaluate the role of lactate dehydrogenase in diabetic neuropathic pain (DNP) and the relationship with peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) in mice.Methods:SPF-grade healthy male C57BL/6J mice, aged 6-8 weeks, weighing 18-22 g, were used to establish diabetes mellitus model by intraperitoneal injection of streptozotocin (STZ) 120 mg/kg. Twenty-four mice with diabetes mellitus were divided into 2 groups ( n=12 each) using a random number table method: DNP group and DNP + oxamate group (OXA group). Another 12 SPF-grade healthy male C57BL/6J mice were selected as control group (C group). In OXA group, oxamate 750 mg/kg was intraperitoneally injected once a day for 28 consecutive days. The equal volume of normal saline was given instead in C group and DNP group. The mechanical paw withdrawal threshold (MWT), blood glucose and body weight were measured at 3 days before STZ injection and at 1, 2, 3 and 4 weeks after STZ injection (T 0-4). After the last behavioural test was completed, blood samples were collected from the posterior orbits of anesthetized mice for determination of serum lactate concentrations. The animals were then sacrificed and the tissues from the prefrontal cortex of the brain were taken for determination of lactate content, mitochondrial membrane potential (by the JC-1), content of reactive oxygen species (ROS) (using dihydroethidium probes), and level of histone lactylation and expression of PGC-1α (by Western blot). Results:Compared with C group, the MWT was significantly decreased at T 2-4, the serum lactate concentrations, contents of lactate and ROS and level of histone lactylation were increased, the mitochondrial membrane potential was decreased, and the expression of PGC-1α was down-regulated in DNP and OXA groups ( P<0.05). Compared with DNP group, no significant change was found in blood glucose and body weight ( P>0.05), the MWT was significantly increased at T 2-4, the serum lactate concentrations, contents of lactate and ROS and level of histone lactylation were decreased, the mitochondrial membrane potential was increased, and the expression of PGC-1α was up-regulated in OXA group ( P<0.05). Conclusions:Lactate dehydrogenase promotes the development of DNP, and the mechanism is related to promotion of increase in histone lactfication and down-regulation of PGC-1α expression in the prefrontal cortex of mice.

Objective:To evaluate the role of spinal cord neuron Src-associated-in-mitosis-68-kDa (SAM68)-transient receptor potential vanilloid-1 channel (TRPV1) signaling pathway in diabetic neuropathic pain (DNP) in mice.Methods:Forty SPF male C57BL/6 mice, aged 8 weeks, weighing 18-22 g, were used in this study. Diabetes mellitus was induced by intraperitoneal streptozotocin 0.12 mg/g, and successful DNP model was defined as decrease in the mechanical paw withdrawal threshold (MWT) of the hind limb≥50% of the baseline value. Twenty-four mice with DNP at 4 weeks after developing the model were divided into 3 groups ( n=8 each) using a simple random sampling: DNP group, SAM68 knocked down group (KD group) and virus control group (VC group). Eight diabetic mice with decrease in MWT <50% were randomly selected as non-DNP group (ND group), and 8 normal mice were randomly selected as control group (NC group). At 4 weeks after developing the diabetes mellitus model, SAM68 gene silencing virus and empty virus were injected into the lumbar enlargement of the spinal cord in KD group and VC group, respectively. MWT was measured before developing the diabetes mellitus model and at 4 and 6 weeks after developing the diabetes mellitus model. The mice were sacrificed after the end of MWT measurement at week 6 after developing the model, spinal cord tissues were collected and the expression of SAM68 and TRPV1 was detected by Western blot, and their localization in the spinal cord was observed by immunofluorescence. Results:Compared with NC and ND groups, the MWT was significantly decreased at 4 and 6 weeks after developing the model, and the expression of SAM68 and TRPV1 in spinal cord tissues was up-regulated in DNP group ( P<0.05). Compared with DNP group, the MWT was significantly increased at 6 weeks after developing the model, the expression of SAM68 and TRPV1 in spinal cord tissues was down-regulated, and no significant change was found in the parameters mentioned above in VC group ( P>0.05). SAM68 and TRPV1 were expressed in neurons in the same region of the spinal cord. Conclusions:Activation of SAM68-TRPV1 signaling pathway in spinal cord neurons is involved in the pathophysiological mechanism of DNP in mice.
