Endoscopic transforaminal lumbar interbody fusion (TLIF) offers substantial advantages in the management of degenerative spinal diseases, including accelerated postoperative recovery. However, its technical complexity and steep learning curve pose risks for nerve root injury. Optimizing nerve root protection in full-endoscopic facet-sparing TLIF (FE fs-TLIF) and full-endoscopic facet-resecting TLIF (FE fr-TLIF) is essential for enhancing surgical safety. This study aimed to improve the nerve root protection in FE fs-TLIF and FE fr-TLIF by optimizing cage glider selection and insertion techniques based on the specific cage shape—banana-shaped or bullet-shaped. The goal was to ensure safe cage positioning and mitigate nerve root injury during discectomy, endplate preparation, and cage insertion. These strategies were validated through cadaveric simulations and clinical implementation. In FE fr-TLIF utilizing bullet-shaped (straight) cages, one-tip and two-tip cage gliders effectively protected the traversing nerve root by facilitating medial cage entry, thereby minimizing irritation of the exiting nerve root. Conversely, in FE fr-TLIF with banana-shaped cages, the lateral tilt of the cage holder during implantation required the use of a two-tip cage glider to protect the traversing and exiting nerve roots, thereby mitigating the potential risk of nerve irritation. In FE fs-TLIF, a one-tip cage glider is preferred for safeguarding the exiting nerve root, while the traversing root is inherently protected by the medial wall of the facet joint. The use of a two-tip cage glider in FE fs-TLIF can cause injury to the nerve root during glider insertion. In addition to the selection of cage gliders, improper cage insertion steps can also contribute to postoperative neurapraxia. The appropriate selection of cage gliders with corresponding insertion techniques is critical for nerve root protection in endoscopic TLIF. Tailoring these choices to the specific approach (FE fs-TLIF or FE fr-TLIF) and cage type (banana or bullet) enhances surgical safety and clinical outcomes.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Electromagnetic fields can regulate the fundamental biological processes involved in bone remodeling. As a non-invasive physical therapy, electromagnetic fields with specific parameters have demonstrated therapeutic effects on bone remodeling diseases, such as fractures and osteoporosis. Electromagnetic fields can be generated by the movement of charged particles or induced by varying currents. Based on whether the strength and direction of the electric field change over time, electromagnetic fields can be classified into static and time-varying fields. The treatment of bone remodeling diseases with static magnetic fields primarily focuses on fractures, often using magnetic splints to immobilize the fracture site while studying the effects of static magnetic fields on bone healing. However, there has been relatively little research on the prevention and treatment of osteoporosis using static magnetic fields. Pulsed electromagnetic fields, a type of time-varying field, have been widely used in clinical studies for treating fractures, osteoporosis, and non-union. However, current clinical applications are limited to low-frequency, and research on the relationship between frequency and biological effects remains insufficient. We believe that different types of electromagnetic fields acting on bone can induce various “secondary physical quantities”, such as magnetism, force, electricity, acoustics, and thermal energy, which can stimulate bone cells either individually or simultaneously. Bone cells possess specific electromagnetic properties, and in a static magnetic field, the presence of a magnetic field gradient can exert a certain magnetism on the bone tissue, leading to observable effects. In a time-varying magnetic field, the charged particles within the bone experience varying Lorentz forces, causing vibrations and generating acoustic effects. Additionally, as the frequency of the time-varying field increases, induced currents or potentials can be generated within the bone, leading to electrical effects. When the frequency and power exceed a certain threshold, electromagnetic energy can be converted into thermal energy, producing thermal effects. In summary, external electromagnetic fields with different characteristics can generate multiple physical quantities within biological tissues, such as magnetic, electric, mechanical, acoustic, and thermal effects. These physical quantities may also interact and couple with each other, stimulating the biological tissues in a combined or composite manner, thereby producing biological effects. This understanding is key to elucidating the electromagnetic mechanisms of how electromagnetic fields influence biological tissues. In the study of electromagnetic fields for bone remodeling diseases, attention should be paid to the biological effects of bone remodeling under different electromagnetic wave characteristics. This includes exploring innovative electromagnetic source technologies applicable to bone remodeling, identifying safe and effective electromagnetic field parameters, and combining basic research with technological invention to develop scientifically grounded, advanced key technologies for innovative electromagnetic treatment devices targeting bone remodeling diseases. In conclusion, electromagnetic fields and multiple physical factors have the potential to prevent and treat bone remodeling diseases, and have significant application prospects.

A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the role and related mechanism of myeloid related differentiation markers (MYADM) in lung adenocarcinoma metastasis induced by high cholesterol diet.Methods:(1) Cell experiments: Using lung adenocarcinoma A549 and H1975 cells, the cells were treated with 0.8 mg/ml cholesterol and then transfected with a lentivirus to knock down MYADM. The overexpression of MYADM was achieved by transfecting the cells with an overexpression plasmid. Western blotting was used to detect the expression levels of MYADM, E-cadherin, β-catenin, MMP-2, MMP-9, and vimentin in the cells. The proliferation ability of the cells was assessed using the plate clonal formation assay, while the migration and invasion ability were evaluated using the Transwell assay. Western blot was used to determine the effects of MYADM knockdown or overexpression on these proteins. Western blot and immunofluorescence assays were conducted to investigate the impact of Akt phosphorylation on the expression of MYADM and Rac1 in cholesterol-treated lung adenocarcinoma cells, as well as the phosphorylation of c-Myc. Western blot was also used to assess the effect of c-Myc knockdown on the expression of MYADM and MCT1 in lung adenocarcinoma cells. Chromatin immunoprecipitation (ChIP) assays were performed to investigate the impact of cholesterol on the binding between c-Myc and the promoters of MYADM and MCT1 in lung adenocarcinoma cells. (2) Animal experiment: A549 cells or A549 cells with MYADM knockdown were intravenously inoculated into BALB/c nude mice, which were then divided into a normal diet group and a high cholesterol diet group. Using a live imaging system, the growth and metastasis of tumors in the mice were monitored. After 42 days, lung tissues were collected for immunohistochemical staining to detect changes in relevant proteins.Results:After cholesterol treatment, the expression level of MYADM in A549 cells increased from 1.00±0.18 to 3.28±0.28 ( P<0.001), and in H1975 cells, it increased from 1.00±0.06 to 2.03±0.10 ( P<0.001). Compared with the control group, the expression of E-cadherin in lung adenocarcinoma cells after MYADM knockdown increased ( P<0.01), while the expressions of β-catenin, MMP-2, MMP-9, and vimentin decreased (all P<0.01). After MYADM knockdown, the number of clonal plates decreased in A549 cells (203±23 vs 60±18, t=8.48, P=0.001) and H1975 cells (298±64 vs 137±51, t=3.41, P=0.271). The number of invasive cells also decreased in A549 cells (212±18 vs 99±34, t=5.09, P=0.007) and H1975 cells (268±34 vs 134±14, t=6.31, P=0.003). Additionally, the number of migratory cells decreased in A549 cells (353±37 vs 124±29, t=8.44, P=0.001) and H1975 cells (279±41 vs 79±19, t=7.67, P=0.002). In the lung adenocarcinoma cells overexpressing MYADM, the expression of E-cadherin decreased ( P<0.01), while the levels of β-catenin, MMP-2, MMP-9, and vimentin increased (all P<0.01). The number of plate clonal colonies formed by lung adenocarcinoma cells overexpressing MYADM increased significantly in A549 cells, (94±26 vs 298±34, t=8.26, P=0.001) and H1975 cells (83±13 vs 331±24, t=15.74, P<0.001). The number of invasive A549 cells also increased (118±17 vs 193±24, t=4.41, P=0.012) and (156±19 vs 321±12, t=12.72, P<0.001). Additionally, the number of migrating cells increased in A549 cells (171±22 vs 284±15, t=7.35, P=0.002) and in H1975 cells (178±7 vs 263±12, t=10.6, P<0.001). Experiments related to the molecular mechanism showed that overexpression of MYADM promotes the expression of MCT1 in lung adenocarcinoma cells (all P<0.01). Cholesterol not only enhances the expression of MYADM in lung adenocarcinoma cells, but also boosts the expression of Rac1 and MCT1, as well as the phosphorylation of Akt and c-Myc (all P<0.05). Immunoprecipitation experiments revealed that in A549 cells treated with cholesterol, MYADM-Rac1 interaction levels increased from (100.0±15.9)% to (191.0±26.7)% ( P=0.007), while in H1975 cells, the levels increased from (100.0±18.2)% to (170.0±27.5)% ( P=0.021). ChIP confirmed that cholesterol treatment enhances the binding of c-Myc to the promoters of MYADM and MCT1. In vivo experiments demonstrated that a high-cholesterol diet promotes the metastasis of lung adenocarcinoma cells in mice, inducing the expression of MYADM, MCT1, and Rac1, as well as the phosphorylation of Akt and c-Myc in mouse lung tissue. Conversely, knocking down MYADM inhibits the metastasis of lung adenocarcinoma cells in mice, suppressing the expression of MYADM, MCT1, and Rac1, as well as the phosphorylation of Akt and c-Myc in mouse lung tissues. Conclusion:Cholesterol may induce lung adenocarcinoma cells proliferation and metastasis by regulating the MYADM/Rac1/Akt/c-Myc/MCT1 axis.

Glycyrrhizic acid is one of the key bioactive components in licorice,known for its liver-protec-tive and antiviral effects.Squalene epoxidase(SQE)is a crucial enzyme in the biosynthetic pathway of glycyrrhizic acid.However,there is limited research on the systematic analysis of the SQE gene family and its function in licorice.This study aims to explore the role of the SQE gene family in glycyrrhizic acid synthesis through bioinformatic analysis,expression specificity,and correlation with glycyrrhizic acid con-tent.The results showed that the three medicinal species of licorice contained a total of 11 SQE genes.Among them,both Glycyrrhiza glabra and Glycyrrhiza inflata had four SQE genes,while Glycyrrhiza ura-lensis had three.Highly homologous SQE genes exhibited similar expression patterns and were located at similar chromosomal positions.Different SQE genes displayed distinct expression characteristics.Specif-ically,GgSQE1,GiSQE1,GuSQE1,and GuSQE3 were primarily expressed in the roots,while GgSQE3 was highly expressed in the whole plant of licorice.Under 15％PEG6000 and 150 mmol/L NaCl treat-ments at different time points during seedling stages of different licorice species,the expression patterns of GgSQE1,GgSQE3,GiSQE1,GiSQE3,and GuSQE1 exhibited trends similar to the changes in glycyr-rhizic acid content.Further analysis revealed that the promoter regions of these genes contained multiple stress-responsive elements,suggesting that SQE1 and SQE3 may be involved in glycyrrhizic acid synthesis following abiotic stress in licorice.The findings of this study provide candidate genes for future breeding programs aimed at improving glycyrrhizic acid content and lay a foundation for further research into the molecular mechanisms by which abiotic stress enhances glycyrrhizic acid production.

Objective To explore the effect and predictive value of ultrasound-guided needling assisted motor evoked potentials(MEP)and electromyography(EMG)monitoring on neurological recovery in spinal surgery.Methods A retrospective analysis was conducted on the clinical data of 80 patients who underwent spinal surgery at Jiangsu Province Hospital of Chinese Medicine from January 2020 to December 2024.A total of 41 patients in the observation group received ultrasound-guided needling assisted MEP and EMG monitoring,and 39 patients in the control group received conventional method for MEP and EMG monitoring.The operative time,intraoperative blood loss,and the proportions of intraoperative MEP and EMG warnings were compared between the two groups,and the sensitivity and specificity of intraoperative MEP monitoring were compared between the two groups.The receiver operating characteristic(ROC)curve was plotted,and the area under the curve(AUC)was calculated to analyze the efficiency of MEP warning in predicting the dysfunction of postoperative spinal cord.Results There were no significant differences in the operative time,intraoperative blood loss,or the proportions of intraoperative MEP and EMG warnings(P>0.05).The sensitivity,specificity and AUC of intraoperative MEP monitoring in the observation group were significantly higher than those in the control group,with statistically significant differences(P<0.05).The sensitivity,specificity,and AUC of postoperative MEP warning in predicting the dysfunction of spinal cord in the observation group were higher than those in the control group,with statistically significant differences(P<0.05).Conclusion Ultrasound-guided needling assisted MEP and EMG monitoring can effectively enhance the intraoperative neural monitoring accuracy,and postoperative MEP warning demonstrates superior predictive value for postoperative neurological dysfunction.
