Objective: This study aimed to explore the correlation between balance function and core muscle activation in patients with adolescent idiopathic scoliosis (AIS), compared to healthy individuals. Methods: A total of 24 AIS patients and 25 healthy controls were recruited. The limits of stability (LOS) test were conducted to assess balance function, while surface electromyography was used to measure the activity of core muscles, including the internal oblique, external oblique, and multifidus. Diaphragm thickness was measured using ultrasound during different postural tasks. Center of pressure (COP) displacement and trunk inclination distance were also recorded during the LOS test. Results: AIS patients showed significantly greater activation of superficial core muscles, such as the internal and external oblique muscles, compared to the control group (p < 0.05). Diaphragm activation was lower in AIS patients during balance tasks (p < 0.01). Although no significant difference was observed in COP displacement between the groups, trunk inclination was significantly greater in the AIS group during certain tasks (p < 0.05). Conclusion These findings suggest distinct postural control patterns in AIS patients, highlighting the importance of targeted interventions to improve balance and core muscle function in this population.

Aim To investigate the synergistic sensiti-zation effect of saikosaponin D(SSD)combined with temozolomide(TMZ)on glioblastoma cells(GBM)and its molecular mechanism.Methods The sensitiv-ity of RG-2,U251 and LN-428 GBM cell lines to SSD and TMZ was analyzed by CCK-8 method combined with HE staining,and the optimal compatible concen-tration was screened.The effect of HE staining com-bined with Hoechst fluorescence staining on the prolif-eration of GBM cell line was detected by clonal forma-tion experiment.The autophagosome formation of GBM cells was observed by monodansylcadaverine(MDC)staining.The expression and distribution of endoplas-mic reticulum stress-related factors and apoptosis and autophagy proteins were detected by Western blot and ICC.Results The sensitivity order of GBM cells to TMZ was RG-2＞U251＞LN-428.The results of com-bined administration showed the synergistic inhibitory effect of SSD combined with TMZ on proliferation of GBM cell lines,which was confirmed by cell cloning formation experiment.Compared with the TMZ group,Hoechst fluorescence staining showed a significant in-crease in the number of nuclear bright staining in the combined administration group.MDC fluorescence staining showed that there were more dense green parti-cles in the cytoplasm of SSD/TMZ plus group than that of TMZ group.Western blot results showed that com-pared with TMZ group,the expression of ER stress markers GRP78,CHOP,p-PERK and ATF6 signifi-cantly increased in SSD/TMZ group(P＜0.05).The expressions of apoptosis proteins caspase-12,caspase-9,caspase-3,cleaved caspase-3,Bax and autophagy proteins LC3 and Beclin-1 significantly increased(P＜0.05),which were verified by ICC test.Conclusions SSD can cooperate with TMZ to inhibit the prolifera-tion of GBM cells and induce apoptosis and autophagy,and enhance the sensitivity of GBM cells to TMZ by ac-tivating endoplasmic reticulum stress pathway.

Aim To investigate the molecular mecha-nism of lysophosphatidylcholine(LPC)-induced neu-trophil extracellular trap formation and the intervening role of quercetin.Methods An in vitro model of NETs formation was constructed using LPC-induced primary rat neutrophils,and quercetin intervention was performed.The formation of NETs and the expression level of related pathway proteins were detected.Results 100 mg·L-1 LPC induced the formation of NETs in vitro,and NETs formation was associated with the up-regulation of LOX-1/NOX2 pathway protein expres-sion.Quercetin intervention effectively decreased LOX-1 and NOX2 protein expression,then inhibiting NETs formation.Conclusions Quercetin inhibits the forma-tion of NETs by regulating the LOX-1/NOX2 signaling pathway and exerting a protective effect against related inflammatory diseases.

Aim To explore the potential genes and mechanism of alisol B in the treatment of non-small cell lung cancer(NSCLC).Methods The proliferation and migration of NSCLC cells were detected by CCK-8 and Transwell.Genes of NSCLC and alisol B were col-lected through TCGA and compound gene prediction database,and their intersection genes were obtained.The network of protein-protein interaction(PPI)was constructed by using String database,and the top 20 key nodes were screened out,and the prognosis-related proteins related to the prognosis of NSCLC were screened out by using R language,and the intersection of them was obtained.The potential mechanism of ali-sol B on NSCLC was explored by KEGG and GO en-richment analysis and the relationship between related genes and immune cells,which was verified by cell-lev-el experiments.Results Alisol B inhibited the cell activity and migration ability of NSCLC cells.Five im-portant genes were identified by network pharmacologi-cal analysis:CCNE1,CDK1,COL1A1,COL1A2 and COL3A1.The results of cell experiment showed that al-isol B down-regulated the expression of Cyclin E1,CDK1 and COL1A2 in NSCLC cells.In addition,alisol B could inhibit the expression of COL1A2 and M2 macrophage marker CD206 in macrophages.Conclu-sions Alisol B may inhibit the proliferation of tumor cells by down-regulating CDK1 and Cyclin E1,and may affect the function of macrophages by inhibiting COL1A2,thus regulating the tumor immune microenvi-ronment and inhibiting NSCLC.

This study was aimed at examining the influence of meteorological factors on scrub typhus in Xiamen.Scrub ty-phus monitoring data and meteorological factors were collected in Xiamen from 2005 to 2023.Spearman correlation analysis and nonlinear regression were used to analyze the correlation between scrub typhus incidence and meteorological factors.The inci-dence of scrub typhus first increased and subsequently decreased in Xiamen from 2005 to 2023.The highest incidence was be-tween 2014 and 2016,and the peak incidence was from June to October.The monthly incidence of scrub typhus positively cor-related with daily minimum temperature(r=0.637,P＜0.001,daily average temperature(r=0.627,P＜0.001),daily maxi-mum temperature(r=0.612,P＜0.001),sunshine duration(r=0.405,P＜0.001),average relative humidity(r=0.346,P＜0.001),and daily rainfall(r=0.207,P=0.002),and negatively correlated with average atmospheric pressure(r=-0.549,P＜0.001),whereas no correlation was observed with the average wind speed in Xiamen.The regression equation of scrub ty-phus monthly incidence and meteorological parameters was y=-433.869-11.503x1+0.381x1 2+9.150x2-0.197x2 2+3.936 x3-0.132x3 2+0.881x4+0.035x4 2-1.048x5+0.009x5 2+0.186x6-0.023x6 2+0.421x7+6.210×10-5x8-1.051 × 10-10x8 2 in Xiamen,and the R2 was 0.473,thus indicating good model fit.Scrub typhus incidence correlated with the daily minimum av-erage temperature,average temperature,daily maximum tem-perature,sunshine duration,daily rainfall,relative humidity,and average atmospheric pressure in Xiamen.Various meteoro-logical factors had differing effects on scrub typhus.
