BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

Glucose metabolic reprogramming is important in promoting the occurrence and development of malignant tumors and meeting the high demands of the malignant proliferation of tumor cells. An in-depth investigation of the mechanism of glucose metabolic reprogramming in lung cancer is important for the development of effective therapeutic strategies for lung cancer. Traditional Chinese medicine (TCM) is characterized by multiple components, targets, and pathways and can exert antitumor effects through multiple mechanisms. This article illustrates systematically the mechanism of action of Chinese herbal monomers and compound formulas regulating glucose metabolic reprogramming in lung cancer and explores deeply their regulatory effects on key enzymes of glycolysis and metabolism-related signaling pathways, and their potential in overcoming the drug resistance of lung cancer. It aims to provide a reference basis for the study of therapeutic targets and mechanisms of action of TCM in prevention and treatment of lung cancer and theoretical sources for the research and development of new medicines.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Numerous research conducted in recent years has revealed that gut microbial dysbiosis, such as modifications in composition and activity, might influence lung tissue homeostasis through specific pathways, thereby promoting susceptibility to lung diseases. The development and progression of lung cancer, as well as the effectiveness of immunotherapy are closely associated with gut flora and metabolites, which influence immunological and inflammatory responses. During abnormal proliferation, non-small cell lung cancer cells acquire more substances and energy by altering their own metabolic pathways. Glucose and amino acid metabolism reprogramming provide tumor cells with abundant ATP, carbon, and nitrogen sources, respectively, providing optimal conditions for tumor cell proliferation, invasion, and immune escape. This article reviews the relationship of immune response with gut flora and metabolic reprogramming in non-small cell lung cancer, and discusses the potential mechanisms by which gut flora and metabolic reprogramming affect the occurrence, development, and immunotherapy of non-small cell lung cancer, in order to provide new ideas for precision treatment of lung cancer patients.

Objective:To observe and assess the clinical value of electrophysiology of ocular surface in the diagnosis and treatment of blepharospasm in Meige syndrome (MS).Methods:A single-center, cross-sectional study. A total of 413 patients diagnosed with MS and undergoing surgical treatment at the Henan Provincial Meige Syndrome Diagnosis and Treatment Center of the Henan Provincial Third People′s Hospital from May 2022 to December 2023 were included as the MS group. A total of 110 age- and gender-matched spouses of patients and community volunteers were selected as the control group. The bioelectricity detection program of the electrooculogram was used; the frequency bandwidth was set at 0.3 to 300.0 Hz. Surface electrodes were employed to record the surface electrophysiological manifestations of the corrugator supercilii muscle and the lower orbicularis oculi muscle, as well as the conditions and temporal characteristics of spasm waves. Based on the amplitude and waveform of the electrophysiology of ocular surface signals, it can be classified into 0-4 grades. The blepharospasm was divided into conditionally induced type, spastic type, reverse spastic type, and oro-ocular elicited type. All patients were treated with neural circuit occlusion, and the postoperative follow-up time was 4.1 (0.5-19.0) months. The distribution of different grades of electrophysiology of ocular surface in the MS and control group at baseline were observed, as well as within the MS group at the last follow-up visit. Additionally, the blepharospasm grades in the MS group were also assessed. The comparison of the distribution of the number of eyes with different grades of electrophysiology of ocular surface between groups was conducted using the Mann-Whitney U test. Results:At baseline, in the MS group, the number of cases with corrugator supercilii muscle amplitudes and morphologies graded from 0 to 4 were as follows: 15 (3.60%, 15/413) for grade 0, 95 (23.00%, 95/413) for grade 1, 142 (34.38%, 142/413) for grade 2, 127 (30.75%, 127/413) for grade 3, and 34 (8.24%, 34/413) for grade 4. In the control group, the corresponding numbers of individuals were 82 (74.54%, 82/110) for grade 0, 24 (21.82%, 24/110) for grade 1, 4 (3.64%, 4/110) for grade 2, 0 (0.00%, 0/110) for grade 3, and 0 (0.00%, 0/110) for grade 4. For the orbicularis oculi muscle, there were 35 cases (8.47%) in grade 0, 124 cases (30.03%) in grade 1, 150 cases (36.32%) in grade 2, 90 cases (21.79%) in grade 3, and 14 cases (3.39%) in grade 4 in the MS group. In the control group, there were 86 cases (78.18%) in grade 0, 24 cases (21.82%) in grade 1, and 0 cases in grades 2, 3, and 4. There were statistically significant differences in the distribution of the number of eyes with different electrophysiology of ocular surface grading of the corrugator supercilii muscle and the orbicularis oculi muscle between the MS and control group ( Z=-14.51, -13.86; P<0.001). Meanwhile, there were statistically significant differences in the distribution of the number of eyes with different electrophysiology of ocular surface grading of the corrugator supercilii muscle and the orbicularis oculi muscle between preoperation and at the last follow-up in the MS group ( Z=-16.52, -17.36; P<0.001). In the MS group, there were 61 (14.77%, 61/413), 306 (74.09%, 306/413), 27 (6.54%, 27/413) and 19 (4.60%, 19/413) cases of blepharospasm conditionally induced type, spasm type, reverse spasm type and oro-ocular elicited type, respectively. Conclusion:The electrophysiology of the ocular surface can objectively reflect the activity of periocular neuromuscular.

Osteoarthritis(OA)is a common joint disease in clinical practice,and cartilage damage is a typical pathological change.The pathogenesis of OA is complex,and various adverse factors can lead to the occurrence of OA.Mitochondria are im-portant organelles within cells and play important roles in cellular physiological and pathological activ-ities.Mitochondrial quality control is an important regulatory mechanism in the body to maintain nor-mal mitochondrial structure and function,mainly including mitochondrial biogenesis,mitochondrial dynamics,mitochondrial autophagy,mitochondrial oxidative stress,and other forms.The imbalance of mitochondrial quality control in chondrocytes is closely related to the occurrence and development of osteoarthritis,and regulating the balance of mi-tochondrial quality control is a potential therapeu-tic point for osteoarthritis.The author reviewed rel-evant research literature in recent years to provide a review of the relationship between mitochondrial quality control and the occurrence and develop-ment of osteoarthritis,in order to provide new ideas and directions for the research and diagnosis and treatment strategies of osteoarthritis.

Objective:To explore the impact of the stimulator of interferon genes(STING)-interferon regulatory factor 3(IRF3)pathway on the senescence of rapid pacing HL-1 myocytes.Methods:HL-1 cells were divided into five groups: the control group(HL-1 cells without any treatment), pacing group(HL-1 cells paced for 48 hours), STING siRNA group(HL-1 cells paced for 48 hours and transfected with STING siRNA), NC siRNA group(HL-1 cells paced for 48 hours and transfected with NC siRNA), and H151 inhibitor group(HL-1 cells paced for 48 hours with the addition of 1 μmol/L STING inhibitor H151). Mitochondrial membrane potential was assessed in control and pacing group cells, and mitochondrial MitoTracker and TFAM co-localization staining was performed on these cells.Cellular senescence was evaluated using β-galactosidase staining in each group, and the positive rate of cellular senescence was observed and calculated.Western blotting was employed to detect the expression levels of STING, IRF3, P-IRF3, P16, P21, and P53 proteins in all groups.Immunofluorescence was utilized to examine the expression distribution of STING and P21 across the various groups.ELISA was performed to measure the concentrations of interleukin(IL)-1β, IL-6, and IL-8 in the cell supernatants from each group as part of the senescence-associated secretory phenotype(SASP).Results:Compared with the control group, the ratio of mitochondrial JC-1 multimer to monomer was significantly decreased in the pacing group( t=16.42, P<0.05), the co-localization of mitochondrial MitoTracker and TFAM in the cells was significantly weakened, the proportion of cells with positive cellular senescence-associated β-galactosidase staining significantly increased in the pacing group, the expression levels of STING, P-IRF3/IRF3, P16, P21, and P53 proteins were significantly elevated in the pacing group, and the concentrations of IL-1β, IL-6, and IL-8 in the cell supernatants were markedly increased.Compared with the pacing group, the proportion of cells with positive cellular senescence-associated β-galactosidase staining decreased in the STING siRNA group and H151 inhibitor group ( F= 18.13, P<0.05), the expression levels of STING, P-IRF3/IRF3, P16, P21, and P53 were reduced in the STING siRNA group and H151 inhibitor group ( F=16.84, 26.56, 74.70, 31.80, 31.23, all P<0.05), and the concentrations of IL-1β, IL-6, and IL-8 in the cell supernatants decreased( F=197.80、1 339.00、1 308.00, all P<0.001). Conclusions:Rapid pacing of HL-1 cells can promote mtDNA release into the cytoplasm, activate the STING-IRF3 pathway, accelerate cellular senescence, and enhance the secretion of SASP.Inhibiting the expression of STING can delay the senescence induced by the rapid pacing of HL-1 cells and reduce SASP secretion.
