BACKGROUND:Compensatory changes in sagittal parameters of the cervicothoracic spine after orthopedic surgery in patients with lumbar degenerative scoliosis and their intrinsic relationship,as well as the impact of these changes on quality of life,are still lacking.OBJECTIVE:To evaluate the compensatory alignment of cervical and thoracic vertebrae after correction of lumbar degenerative scoliosis.METHODS:103 patients who underwent surgical correction of lumbar degenerative scoliosis were included in this study.Patients'demographic characteristics and spinal sagittal parameters were assessed,and prediction equations between changes in cervical sagittal parameters and lumbar deformity correction were attempted.Simultaneously,the SRS-22 scale was used to assess the quality of life of patients and to explore the relationship between the compensatory changes of the cervical and thoracic spine after correction and the patients'health-related quality of life.RESULTS AND CONCLUSION:(1)At 3 months and 2 years after surgery,all indicators of the cervical spine and thoracic spine were significantly improved compared with those before surgery(P＜0.05),but there was no significant change at 3 months after surgery compared with 2 years after surgery(P＞0.05).At 3 months and 2 years after surgery,the lumbar spine parameters including lumbar lordosis,C7-S1 sagittal vertical axis,and pelvic incident-lumbar lordosis had significant changes compared with those before surgery(P＜0.05),but the change was not significant at 3 months after surgery compared with 2 years after surgery(P＞0.05).(2)Correlation analysis showed that the lumbar lordosis was highly correlated with the C3-C7 cervical lordosis,C1-C7 cervical lordosis,C2-7 sagittal vertical axis,thoracic inlet angle,and C7-S1 sagittal vertical axis(|r|≥ 0.5,P＜0.000 1).The lumbar lordosis was correlated with the thoracic kyphosis(r=-0.280).(3)Two prediction formulas were established for compensatory changes in cervical spine:cervical lordosis=0.524x,lumbar lordosis=-6.612,C2-7 sagittal vertical axis=-0.263x,and lumbar lordosis=-5.436(P＜0.05,R2＞0.6).(4)When postoperative C2-7 sagittal vertical axis was between 14.4 and 26.8 mm;cervical lordosis was between 9° and 41°,lumbar lordosis was between 42.7° and 68.7°,and sagittal vertical axis was between-40 and 40 mm,patients had better quality of life recovery.(5)It is indicated that significant compensatory changes in the sagittal plane of the cervical spine can be observed after correction of lumbar degenerative scoliosis.We found that each 1° increase in lumbar lordosis was associated with a corresponding increase of about 0.5° in cervical lordosis and a corresponding decrease of about 0.3 mm in the vertical axis of the C2-7 sagittal plane.Patient satisfaction was higher if compensatory changes were closer to normal sagittal plane.

Objective:To investigate the impacts of total salvianolic acid(TSA)on macrophage polarization and mesenchymal macrophage infiltration in liver cancer bearing mice by regulating the Toll-like receptor 4(TLR4)/myeloid differentiation factor 88(MyD88)/nuclear factor-κB(NF-κB)pathway.Methods:Mice were randomly separated into liver cancer group,TSA low concentra-tion group,TSA medium concentration group,TSA high concentration group,TSA high concentration+TLR4 inhibitor(TAK242)group and control group,with 12 mice in each group.Except for control group,mice in all other groups were injected subcutaneously into the right axilla to construct liver cancer models by intraperitoneal transmission of third-generation H22 cell suspension.After suc-cessful modeling,administration was carried out once a day for 2 weeks.Changes in tumor weight,tumor volume,spleen index and thymus index were detected.Immunofluorescence was applied to detect proportions of CD86 and CD206 positive cells in tumor tissue.ELISA was applied to detect levels of inducible nitric oxide synthase(iNOS),IL-6 and IL-10 in tumor tissues.Flow cytometry was ap-plied to detect proportion of CD11b+F4/80+in tumor tissue.Western blot was applied to detect TLR4,p-NF-κB P65 and MyD88 pro-teins in tumor tissue.The life quality and survival rate of mice were observed.Results:Compared with control group,spleen index,thymus index,proportion of CD86 positive cells in tumor tissue,levels of iNOS and IL-6,and expressions of TLR4,p-NF-κB P65 and MyD88 proteins were reduced in liver cancer group,while proportion of CD206 positive cells and level of IL-10 in tumor tissue were increased(P<0.05).Compared with liver cancer group,tumor weight and volume of mice in TSA low,medium,high concentration groups were decreased,while survival rate,spleen index,thymus index,proportion of CD86 positive cells in tumor tissue,levels of iNOS and IL-6,and expressions of TLR4,p-NF-κB P65 and MyD88 proteins were increased,proportion of CD206 positive cells,level of IL-10,and proportion of CD11b+F4/80+in tumor tissue decreased(P<0.05).TAK242 reversed the effects of high concentration TSA on macrophage polarization and myeloid macrophage infiltration in liver cancer bearing mice.Conclusion:TSA may promote M1 polari-zation of macrophages in liver cancer bearing mice and inhibit myeloid macrophage infiltration by activating the TLR4/MyD88/NF-κB pathway.

BACKGROUND:Previous studies found that the proliferative scar-specific long non-coding RNA lncRNA HSFAS is a novel biomarker that can be used in the diagnosis of hypertrophic scar,but how it functions in hypertrophic scar is not clear. OBJECTIVE:To investigate the role and mechanism of lncRNA HSFAS in hypertrophic scar.METHODS:Fresh scar tissue and surrounding normal skin tissue samples from three patients with hypertrophic scar were collected,and tissue immunofluorescence was used to detect the expression of lncRNA HSFAS in frozen sections of two skin tissues. Primary fibroblasts were isolated from proliferative scarred skin tissue and normal skin tissue and cultured by enzyme digestion method. Quantitative real-time PCR was used to detect the mRNA expression of lncRNA HSFAS in cells. The proteins bound to lncRNA HSFAS were detected by RNA pull-down combined mass spectrometry. GO and KEGG were used to analyze the main functions and pathways of lncRNA HSFAS involved in hypertrophic scar progression. The targeted binding of lncRNA HSFAS to proteins was determined by catRAPID and RPISeq website analysis. RESULTS AND CONCLUSION:Compared with normal skin tissue and fibroblasts from normal skin tissue,the expression of lncRNA HSFAS in human hypertrophic scar tissue and primary fibroblasts from hypertrophic scar tissue was significantly increased (P<0.05). There were 510 proteins clearly bound to lncRNA HSFAS by RNA pull-down combined mass spectrometry. The results of GO and KEGG analyses showed that these proteins were mainly involved in RNA splicing and processing,chromosome synthesis and separation,and cell cycle. Among them,the proteins involved in RNA splicing and processing included scaffold attachment factor B2 and DICER1,and the binding fraction with lncRNA HSFAS was higher. The results of bioinformatics analysis showed that lncRNA HSFAS was bound to scaffold attachment factor B2 and DICER1 proteins. To conclude,lncRNA HSFAS may affect gene expression by interacting with scaffold attachment factor B2 and DICER1 proteins to regulate RNA splicing and processing modification,thus promoting the occurrence and development of hypertrophic scar.

Objective:To evaluate the advantages and short-term clinical effects of totally robotic Nissen 360° fundoplication compared with laparoscopic surgery.Methods:A retrospective analysis was conducted on data of 110 patients undergoing Nissen 360° fundoplication at the Second Department of General Surgery, Yan'an Hospital Affiliated to Kunming Medical University from Aug 2023 to Aug 2024. Among them, 50 cases underwent totally robotic fundoplication, and 60 cases underwent laparoscopic fundoplication. By comparing and analyzing the fatigue level of the primary surgeon during the operations, postoperative incisional pain in patients, swallowing function recovery and the time to resume a normal solid-food diet within 3 months post-surgery, the advantages of totally robotic surgery were evaluated. Additionally, by examining the postoperative recovery of reflux symptoms, postoperative patient comfort, and satisfaction levels in both groups, the short-term clinical outcomes of totally robotic surgery were assessed.Results:Both groups of patients successfully completed the surgeries without any intraoperative or postoperative complications occurring. The fatigue score of the primary surgeon in the totally robotic group was significantly better than that in the laparoscopic group[ (2.34±1.38) vs. (2.89±1.51), t=1.385, P<0.01]. The time taken to resume a normal solid-food diet postoperatively in the totally robotic group was significantly shorter than that in the laparoscopic group[ (27.90±6.77) d vs. (40.78±13.60) d, t =5.765, P<0.01]. Moreover, the postoperative pain comfort level was better in the robotic group than in the laparoscopic group [(1.65±0.72) points vs. (2.23±0.59) points, t=3.742, P<0.01]. Within 12 months postoperatively, the GERD-Q scores in the totally robotic group decreased significantly, and reflux symptoms disappeared, comparable to that in the laparoscopic group. Conclusions:The totally robotic Nissen 360° fundoplication leads to lower fatigue levels for the surgeon. Patients experience significant advantages in terms of postoperative pain perception and dietary recovery. Additionally, it demonstrates excellent postoperative anti-reflux efficacy, high patient comfort, and the surgery is safe and reliable.

Objective:To analyze the association between inflammation-related dietary patterns and the risk for cognitive impairment in older adults aged ≥65 years in longevity areas in China by using reduced rank regression (RRR) analysis.Methods:This study used cross-sectional data from the 2021 Healthy Aging and Biomarkers Cohort Study, including the information about study participants' demographic characteristics, lifestyles, daily life activities, and disease histories. Dietary intake was obtained by using a simplified food frequency questionnaire. Cognitive impairment was evaluated based on the Mini-Mental State Examination Scale combined with years of education. Fasting venous blood samples were collected to detect inflammatory markers, especially high-sensitivity C-reactive protein (hs-CRP) and the platelet-to-lymphocyte ratio (PLR). RRR analysis was used to obtain inflammation-related dietary patterns using hs-CRP and PLR as response variables. Multivariate logistic regression model was used to analyze the association between dietary pattern score and the risk for cognitive impairment. Restricted cubic spline was used to explore the dose response relationship, and mediation analysis was used to quantify the mediating effects of hs-CRP and PLR.Results:Two dietary patterns were identified with RRR. The primary pattern was characterized by higher intakes of flour, red meat, and dairy products, and lower intake of fresh vegetables, explaining 6.84% of the variance in food intake and 0.50% of the variance in inflammatory markers. Compared with the T1 group, the T3 group had significantly higher risk for cognitive impairment ( OR=1.242, 95% CI: 1.034-1.491). Each one standard deviation increase in the dietary pattern score was associated with an 8.7% increase in the risk for cognitive impairment ( OR=1.087, 95% CI: 1.008-1.172), with a significant linear trend (overall-model P<0.001, non-linear P=0.295). Mediation analysis indicated that hs-CRP mediated 6.2% of the association between the dietary pattern and the risk for cognitive impairment. Conclusion:The inflammation- related dietary pattern characterized by higher consumption of flour, red meat, and dairy products and lower consumption of fresh vegetables is associated with an increased risk for cognitive impairment in older adults, and hs-CRP partially mediates this association.
