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.

Diffuse large B-cell lymphoma (DLBCL) is a highly heterogeneous disease. Although standard first-line regimens can cure >50% of patients, approximately one-third of them develop relapsed/refractory DLBCL (r/r DLBCL). Consequently, immunotherapy targeting molecular abnormalities has become pivotal for managing r/r DLBCL. The results of this review show that with advances in understanding DLBCL pathogenesis and the tumor immune microenvironment, antibody-based therapies have evolved rapidly, progressing from monoclonal antibodies (e.g., rituximab, tafasitamab) to bispecific antibodies(e.g., odronextamab,glofitamab, epcoritamab) and antibody-drug conjugate (e.g., polatuzumab vedotin, loncastuximab tesirine). These engineered agents enhance immune cytotoxicity and tumor-specific targeting, providing novel therapeutic options for r/r DLBCL patients.
3.Status of tuberculosis prevention and control knowledge with perceived stress among college and middle school students with pulmonary tuberculosis in Yantai
Chinese Journal of School Health 2025;46(12):1706-1710
Objective:
To understand the current status of tuberculosis prevention and control knowledge and perceived stress among college and middle school students with pulmonary tuberculosis (PTB) in Yantai City, and to analyze the related factors, so as to provide a basis for the school to carry out health education and psychological counseling.
Methods:
A matched case control study was conducted, with 100 PTB student patients in junior high school and above who were diagnosed at designated medical institutions from October 2020 to October 2024. Four healthy control students of the same gender, same dormitory, or same class were selected for each case. Therefore, 100 cases and 400 controls were investigated by questionnaire. The following information was collected: personal basic information; tuberculosis prevention and control awareness; and scores of the Chinese Perceived Stress Scale (CPSS). Conditional Logistic regression model and mixed linear models were used to compare the PTB prevention and control awareness rate, as well as the perceived stress between the case and control groups. Multiple linear regression analysis was used to analyze the factors that may affect the perceived stress of students with PTB.
Results:
The awareness rates of four tuberculosis knowledge items (symptoms of PTB, main causes of onset after infection, consequences of PTB patients not receiving standardized and complete treatment, the most important method to prevent PTB) were higher in the case group (40.00%, 72.00% , 38.00%, 49.00%) than the control group (21.50%, 57.50%, 22.25%, 31.25%) and the differences were statistically significant ( Wald χ 2=18.44, 8.78, 13.20, 16.89, all P <0.01). The tension score (10.49±4.20), loss of control score ( 11.21± 4.58), and total score (21.70±6.88) in the case group were higher than the control group (9.35±4.73, 9.75±5.60, 19.09±8.36) and the differences were statistically significant ( t =2.21, 2.42, 2.88, all P <0.05). The results of multiple linear regression analysis showed that age ≥ 18 years and family history of tuberculosis were the related factors affecting the overall perceived stress and tension of college and middle school students with PTB ( B total scores =4.50, 5.91; B tension score =2.39, 3.23, all P <0.05).
Conclusions
The tuberculosis prevention and control awareness rate, and the perceived stress of college and middle school students with PTB in Yantai are both higher than students without tuberculosis. Moreover, the perceived stress of students with PTB who are aged ≥18 years or have a family history of tuberculosis is even higher.

Objective:
To investigate the effect of loss of function of lanosterol synthase( LSS) gene on intestinal function in a mouse model of non-alcoholic fatty liver disease( NAFLD) induced by a high-fat diet.
Methods:
LSS gene heterozygous knockout C57 mice ( LSS + / -) were established using the CRISRP / Cas9 system.After being fed a high-fat diet with 60% fat content for 6 months,the fat deposition in liver tissues was detected by HE and Oil red O staining,the morphological changes of small intestine tissue were detected by HE staining.The changes in total cholesterol content in intestinal tissue were detected by kits.The gastrointestinal motility function of mice was detected by phenol red paste.The intestinal permeability was detected by Evans blue staining,and the expression of LSS,tight junction protein ( Claudin) -1,Claudin-5,cluster of differentiation 36 ( CD36) ,and Niemann-Pick type C1-like 1 protein ( NPC1L1) proteins in small intestinal tissues were detected by Western blot.
Results :
The results of HE and Oil red O staining of liver tissues showed that liver fat deposition in LSS gene heterozygous knockout mice was lower than that in wild-type mice in the high-fat diet group.The total cholesterol content in intestinal tis- sue of LSS gene heterozygous knockout mice decreased ( P <0. 01) ,but no morphological differences were ob- served between the two groups of mice by HE staining of intestinal tissues.The gastrointestinal motility function of LSS gene heterozygous knockout mice did not show significant changes.The intestinal permeability of LSS gene het- erozygous knockout mice in the high-fat diet group decreased as detected by Evans blue ( P<0. 05) .The expres- sion levels of Claudin-5 protein in the intestinal tissue of LSS gene heterozygous knockout mice in the high-fat diet group increased ( P <0. 05 ) ,while the expression of LSS protein in the intestinal tissues of LSS heterozygous knockout mice decreased ( P <0. 05) .
Conclusion
In the NAFLD model induced by a high-fat diet,LSS gene heterozygous knockout reduces liver fat deposition induced by a high-fat diet and improves intestinal barrier function by regulating cholesterol metabolism in intestinal tissues and up-regulating the expression of Claudin-5.

To explore the variation laws of volatile oil during the extraction process of Artemisiae Argyi Folium and its impact on the quality of the medicinal solution, as well as to achieve precise control of the extraction process, this study employed headspace solid phase microextraction gas chromatography-mass spectrometry(HS-SPME-GC-MS) in combination with multiple light scattering techniques to conduct a comprehensive analysis, identification, and characterization of the changes in volatile components and the physical properties of the medicinal solution during the extraction process. A total of 82 volatile compounds were identified using the HS-SPME-GC-MS technique, including 21 alcohols, 15 alkenes, 14 ketones, 9 acids, 6 aldehydes, 5 phenols, 3 esters, and 9 other types of compounds. At different extraction time points(15, 30, 45, and 60 min), 71, 72, 64, and 44 compounds were identified in the medicinal solution, respectively. It was observed that the content of volatile components gradually decreased with the extension of extraction time. Through multivariate statistical analysis, four compounds with significant differences during different extraction time intervals were identified, namely 1,8-cineole, terpinen-4-ol, 3-octanone, and camphor. RESULTS:: from multiple light scattering techniques indicated that at 15 minutes of extraction, the transmittance of the medicinal solution was the lowest(25%), the particle size was the largest(0.325-0.350 nm), and the stability index(turbiscan stability index, TSI) was the highest(0-2.5). With the extension of extraction time, the light transmittance of the medicinal solution improved, stability was enhanced, and the particle size decreased. These laws of physicochemical property changes provide important basis for the control of Artemisiae Argyi Folium extraction process. In addition, the changes in the bioactivity of Artemisiae Argyi Folium extracts during the extraction process were investigated through mouse writhing tests and antimicrobial assays. The results indicated that the analgesic and antimicrobial effects of the medicinal solution were strongest at the 15-minute extracting point. In summary, the findings of this study demonstrate that the content of volatile oil in Artemisiae Argyi Folium extracts gradually decreases with the extension of extraction time, and the variation in volatile oil content directly influences the physicochemical properties and pharmacological efficacy of the medicinal solution. This discovery provides important scientific reference for the optimization of Artemisiae Argyi Folium extraction processes and the development and application of process analytical technologies.

The AP2/ERF transcription factor family is a class of transcription factors widely present in plants, playing a crucial role in regulating flowering, flower development, flower opening, and flower senescence. Based on transcriptome data from flower, leaf, and stem samples of two Lonicera macranthoides varieties, 117 L. macranthoides AP2/ERF family members were identified, including 14 AP2 subfamily members, 61 ERF subfamily members, 40 DREB subfamily members, and 2 RAV subfamily members. Bioinformatics and differential gene expression analyses were performed using NCBI, ExPASy, SOMPA, and other platforms, and the expression patterns of L. macranthoides AP2/ERF transcription factors were validated via qRT-PCR. The results indicated that the 117 LmAP2/ERF members exhibited both similarities and variations in protein physicochemical properties, AP2 domains, family evolution, and protein functions. Differential gene expression analysis revealed that AP2/ERF transcription factors were primarily differentially expressed in the flowers of the two L. macranthoides varieties, with the differentially expressed genes mainly belonging to the ERF and DREB subfamilies. Further analysis identified three AP2 subfamily genes and two ERF subfamily genes as potential regulators of flower development, two ERF subfamily genes involved in flower opening, and two ERF subfamily genes along with one DREB subfamily gene involved in flower senescence. Based on family evolution and expression analyses, it is speculated that AP2/ERF transcription factors can regulate flower development, opening, and senescence in L. macranthoides, with ERF subfamily genes potentially serving as key regulators of flowering duration. These findings provide a theoretical foundation for further research into the specific functions of the AP2/ERF transcription factor family in L. macranthoides and offer important theoretical insights into the molecular mechanisms underlying floral phenotypic differences among its varieties.
