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.

Objective: To investigate the characteristics and trend of stroke incidence in Yixing City, Jiangsu Province from 2016 to 2023, so as to provide the reference for formulating prevention and control strategies of stroke. Methods: Data of stroke case in Yixing City from 2016 to 2023 were collected from the National Health Information Platform of Yixing City, including sex, age, time of onset, and diagnostic subtypes. Crude incidence was standardized using the data from the 2010 Chinese National Population Census to analyze the characteristics of stroke incidence. The incidence trend of stroke was analyzed by average annual percent change (AAPC). Results: A total of 54 157 stroke cases were reported in Yixing City from 2016 to 2023, with a crude incidence of 629.52/100 000 and a standardized incidence of 299.50/100 000, showing an upward trend (AAPC=9.744% and 5.955%, both P<0.05). The crude and standardized incidence of stroke in males were significantly higher than those in females (695.30/100 000 vs. 565.79/100 000, 328.73/100 000 vs. 270.71/100 000, both P<0.05). Stroke incidence exhibited an age-dependent increase (P<0.05), peaking in the ≥60 years age group (1 820.43/100 000). The crude and standardized incidence of ischemic stroke (555.46/100 000 and 262.26/100 000) were significantly higher than those of hemorrhagic stroke (52.80/100 000 and 28.03/100 000, both P<0.05). From 2016 to 2023, the standardized incidences of stroke in males, females, the 0-<40 years age group, the 40-<60 years age group, the ≥60 years age group, and ischemic stroke all showed an upward trend (AAPC=6.692%, 4.925%, 5.607%, 5.777%, 5.698%, and 8.481%, respectively, all P<0.05). No significant temporal trend was observed for hemorrhagic stroke incidence (P>0.05). Conclusions The incidence of stroke among residents in Yixing City showed an upward trend from 2016 to 2023, with males and elderly individuals being high-risk populations. Ischemic stroke emerged as the predominant subtype, while a concerning trend of increasing stroke incidence among younger adults was observed.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

Objective:To investigate the effect of circulating plasma cell(CPC)on the prognosis of multiple myeloma(MM),and to es-tablish and validate a modified CPC-RISS staging system based on CPC and RISS.Methods:A retrospective analysis was performed for the clinical data of 639 treatment-na?ve patients with MM who were treated in Department of Hematology,Xijing Hospital,from January 2006 to June 2023.Peripheral blood smear was used to calculate the percentage of CPC in patients,and the impact of CPC and other related factors on the prognosis of MM patients was analyzed.A CPC-RISS staging system was established based on RISS stage and the percentage of CPC,and the differences in survival and prognosis were analyzed between patients with different stages.Results:Compared with the patients without CPC,detectable CPC was significantly associated with various high-risk factors for MM,and the MM patients with CPC had a lower complete remission rate and shorter overall survival time and progression-free survival time.The modified CPC-RISS staging system was used to classify the patients with MM into four stages,and there were significant differences in median survival time and progression-free survival time between the patients with different stages of MM.Conclusion:The MM pa-tients with the presence of CPC exhibit more aggressive features,worse response to treatment,and a reduction in long-term survival rate.The modified CPC-RISS staging system can effectively predict the prognosis of treatment-na?ve MM patients.

Objective To compare the efficacy of low-frequency and high-frequency repetitive transcranial magnetic stimulation(rTMS)in patients with tremor-dominant Parkinson's disease.Methods A total of 88 tremor-dominant Parkinson's disease patients who visited Suqian Hospital of Nanjing Drum Tower Hospital Group from January 2021 to June 2024 were randomly assigned to low-frequency rTMS group(treated by 1 Hz stimulation)and high-frequency rTMS group(treated by 5 Hz stimulation),with 44 patients in each group.Treatment was administered once a day,five times a week,for 4 weeks.Another 50 patients were enrolled as the control group.During the rTMS treatment,regular medications were continuously administrated.Before and after treatment,the following assessments were conducted:unified parkinson's disease rating scale part Ⅲ(UPDRS-Ⅲ),Parkinson's disease questionnaire-39(PDQ-39),timed up and go(TUG)test,tremor amplitude,tremor peak frequency,and cortical excitability(resting motion threshold[rMT]and active motion threshold[aMT]).Results After treatment,there were significant differences in the UPDRS-Ⅲ score,TUG time,PDQ-39 score,rMT and aMT values,and tremor amplitude between the two groups(P<0.05),and the high-frequency rTMS group was lower/shorter than the other two group.There was no significant difference in tremor peak frequency between the two groups(P>0.05).Conclusion Both low-frequency and high-frequency rTMS can significantly improve motor function and quality of life in tremor-dominant Parkinson's disease patients.High-frequency rTMS demonstrates better efficacy in improving various symptoms and provides a more effective treatment option for tremor-dominant Parkinson's disease.

BACKGROUND:The application of orthodontic force triggers autophagy in the periodontal tissue via diverse signaling pathways,augmenting or attenuating the activity of relevant cell types such as periodontal ligament cells,osteocytes,osteoclasts,and osteoblasts,thus facilitating the process of periodontal remodeling. OBJECTIVE:To review the research progress in orthodontic force mediated autophagy in periodontal tissue and its impact on orthodontic tooth movement. METHODS:The PubMed,Web of Science,China Biology Medicine disc and CNKI were searched for literature published from 2010 to 2023 to summarize the progress in orthodontics-related autophagy.And 76 papers were finally included in the analysis and discussion. RESULTS AND CONCLUSION:Orthodontic force can trigger a series of biochemical signal changes through periodontal mechanical receptors and aseptic inflammation they cause,leading to autophagy in periodontal tissue.Subsequently,autophagy generates corresponding feedback through cascaded amplified signaling pathways such as Phosphoinositide 3-kinase/protein kinase B,Hippo,and mitogen-activated protein kinase pathways,promoting periodontal tissue remodeling and ultimately achieving tooth movement and stability.Orthodontic force-induced autophagy can differentially regulate bone resorption on the tooth pressure side and bone formation on the tension side.Related targets have good prospects in the clinical application of orthodontic treatment.Orthodontics and autophagy have complex mechanisms.However,existing research has only focused on exploring the role of autophagy in orthodontic tooth movement.Further exploration is needed to investigate the mutual regulatory effects between autophagy and orthodontic tooth movement,as well as the interactions between upstream mechanical receptors and signaling pathways involved in related pathways.

Objective:To evaluate the relationship between gluten-free diet and rheumatoid arthritis (RA).Methods:Data were obtained from large-scale genome-wide association studies (GWAS), and genetic loci that are independent of gluten-free diet and RA of people of Europe2 were selected as instrumental variables. The gluten-free diet GWAS data included 64 949 individuals and 9 851 867 controls. Data were obtained from GWAS of 58 284 RA patients and 13 108 512 controls. The inverse variance weighted (IVW), MR Egger, weighted median method and weighted model were used to conduct two sample Mendelian randomization (MR) analysis. Cochran Q test and mendelian randomness pleiotropy residual sum and outlier (MR-PRESSO) were used to assess SNP heterogeneity. Applying the MR Egger intercept to test the level pleiotropy of SNP. The sensitivity analysis of the "leave one method" that evaluates whether MR studies were influenced by a single SNP. Results:After matching GFD and RA data, three SNPs were included as instrumental variables in the study. IVW showed that GFD could significantly reduce the risk of RA ( β=-60.83, s x=3.82, P<0.001). The weighted median method and weighted pattern also showed that the gluten free diet could reduce the risk of RA ( β=-57.97, s x=4.41, P<0.001; β=-55.81, s x=5.10, P=0.008). Sensitivity analysis of the correlation between GFD and RA showed that there might be heterogeneity between SNPs (Cochran Q test, Q=12.80, P=0.002). The MR-PRESSO results showed that no abnormal SNP was detected ( P=0.174). The forest map showed that SNPs was closely related to GFD and RA stability. The method comparison chart showed that the results of multiple testing methods were basically consistent. The funnel plot showed that SNPs were basically symmetrical, indicating that there was no pleiotropy in MR analysis. The MR Egger intercept test showed no horizontal pleiotropy in MR analysis (intercept value was-0.24, P=0.174). The sensitivity analysis of the "leave one method" is suggested that no single SNP had a significant impact on the overall results. Conclusion:Gluten free diet is related to the risk reduction of RA.

Transcatheter aortic valve implantation (TAVI) is an important alternative in treating high-risk patients with aortic valve regurgitation. Transcatheter tricuspid valve implantation (TTVI) is also an important treatment option for high-risk patients with tricuspid regurgitation. We reported a 72-year male patient who underwent TAVI due to severe aortic valve regurgitation using a J-Valve. During a two-year follow-up, the patient developed secondary tricuspid regurgitation to atrial fibrillation, and subsequently received TTVI using a LuX-Valve. Following the interventions, the patient's symptoms were significantly improved, and echocardiography indicated good hemodynamic performance of both transcatheter heart valves. This case highlights the feasibility and effectiveness of performing multiple valve implantations via transcatheter approaches in high-risk elderly patients.

Objective:To investigate the immunophenotypic and molecular biological characteristics of patients with elevated serum alpha-fetoprotein (AFP) and enteroblastic differentiated gastric adenocarcinoma (GAED).Methods:The clinicopathological data of 13 patients with elevated serum AFP and GAED admitted to Shanxi Cancer Hospital from 2018 to 2020 were collected. Immunohistochemistry (IHC) and next-generation sequencing (NGS) were used to analyze the immune markers and molecular biological characteristics of the pathological tissues of the patients. Kaplan-Meier method and log rank test were used for survival analysis.Results:Among the 13 patients with GAED, 12 were male and 1 was female, aged 41-70 years, with a median age of 64 years. The lesions were mainly located in the gastric antrum (5 cases) and gastric body (4 cases). IHC results showed that the tumor embryonic protein (AFP, SALL4, GPC3), intestinal epithelial differentiation protein (CDX-2, CD10), and some original intestinal epithelial phenotype markers (OCT3/4, Claudin6) were expressed in the tumor tissues. Combined application of multiple markers can reduce the rate of missed diagnosis. Among the 13 patients, 12 had at least one mutation (1 mutation: 1 case, 2-5 mutations: 3 cases, 6-15 mutations: 8 cases), and 1 case was not detected. The gene with the highest mutation frequency was TP53 (10 cases), and other mutant genes included EPHB1 (3 cases), ATRX (2 cases), EPHA5 (2 cases), GATA3 (2 cases), LRP1B (2 cases) and MAP2K4 (2 cases) were also detected. Three of the 13 patients had structural variations, which were C14orf177- GNAS, AIM1- FGFR3, and EPHA6- ROS1 gene rearrangements. All 13 patients had copy number variation, and 11 patients had copy number variation of more than 2 genes. The common amplification genes were IRS2 (5 cases), PTEN (5 cases), GNAS (4 cases), CCNE1 (3 cases), CEBPA (3 cases), PCK1 (3 cases) and ERBB2 (2 cases). The common deletion genes were SOX2 (5 cases) and MYC (5 cases). Among the 13 patients, 4 died, and 2 of the dead patients had liver metastasis. There were 4 patients with disease-free survival and 5 patients with disease progression, including 3 cases of abdominal metastasis and 2 cases of liver metastasis. The 3-year survival rate of patients was 65.9 %, and the 3-year progression-free survival rate was 30.7 %. Gene LRP1B point mutation was associated with poor prognosis ( P＜0.001). There was no significant improvement in the prognosis of patients treated with immunotherapy compared with those treated with chemotherapy alone ( P=0.595), but the prognosis of patients treated with postoperative chemotherapy or postoperative chemotherapy plus immunotherapy was better than that of patients treated with surgery alone ( P＜0.05). Conclusions:Elevated serum AFP with GAED is a highly invasive tumor with unique molecular characteristics, often accompanied by multiple molecular events. TP53 mutation is the most common type of gene mutation. In addition, some cases are accompanied by HER2 amplification and gene rearrangement.
