Objective To investigate the independent risk factors for hypertrophic cardiomyopathy(HCM)with atrial fibrillation(AF)based on cardiac magnetic resonance(CMR)using logistic regression analysis.Methods We reviewed 80 patients diagnosed with HCM at our hospital between January 2022 and December 2023.Statistical differences in the CMR and clinical parameters between patients with HCM with and without AF were compared.The cut-off value of HCM with AF was obtained by receiver operator characteristic curve,and binary logistic regression analysis was performed on statistically significant variables to identify independent risk factors for HCM in patients with AF.Results Univariate analysis showed that there were significant differences in the type of left ventricular late gadolinium enhancement(LGE),native T1 mapping value of the left ventricular myocardium without LGE,left atrial anteroposterior diameter,number of left ventricular LGE myocardial segments,and LGE in the basal anterior interventricular septum,mid anterior interventricular septum,and mid inferior interventricular septum were between HCM with and without AF(P＜0.05).Multivariate analysis revealed that there were significant differences in left ventricular subendocardial LGE(P=0.048,OR=5.3,95％CI:0.642-43.311),native T1 mapping value of left ventricular myocardium without LGE≥1 247 ms(P=0.03,OR=5.7,95％CI:0.734-27.41),and left atrium anteroposterior diameter 50 mm(P=0.013,OR=6.9,95％CI:1.489-31.538)between HCM with and without AF.Conclusion Left ventricular subendocardial LGE,native T1 mapping value≥1 247 ms,and left atrium anteroposterior diameter≥50 mm are independent risk factors for HCM with AF.

Objective To develop a system for retrieving information from clinical records of Traditional Chinese Medicine(TCM)based on generative large language models(LLMs).Methods Applicational needs of the system were analyzed,and entity types to be retrieved were identified.The functions,workflows,and architecture of the system were designed by combining the automatic retrieval capabilities of LLMs with human-in-the-loop(HITL).The software was developed using such frameworks as vLLM and Node.js.Interaction of multiple commercial/open source LLMs was implemented using OpenAI-compatible interfaces.The quality of information retrieved from LLMs was enhanced by prompt engineering.Results This system supported task allocation,automatic retrieval of structured information,and manual review.To evaluate its performance,the moonshot-v1-8k model was used to retrieve clinical records of TCM before manual edition was performed.Combining large language model pre-annotation with meticulous annotator edits improved accuracy by 26.6％compared to the BERT-BiLSTM-CRF model,and enhanced extraction efficiency by 1.6-fold relative to purely manual methods.Conclusion General generative LLMs can retrieve a wide range of entity information from TCM records with high accuracy and scalability.The design and implementation of this system approach may provide a useful reference for developing other biomedical information retrieval systems.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease caused by abnormal amplification of the CAG repeat of the huntingtin (HTT) gene. Its main clinical manifestations are movement disorders,cognitive decline,and psychiatric symptoms. The occurrence and development of HD is related to a variety of factors,and with the deepening of basic research,the relationship between mitochondrial dysfunction,including decreased energy production,abnormal mitochondrial dynamics,and calcium homeostasis. Huntington's disease has attracted more and more attention from researchers. In this review,we discuss the links that exist between the many forms of mitochondrial dysfunction and HD,with the aim of highlighting the important role of mitochondrial dysfunction in the development and progression of HD disease.

Objective To evaluate the feasibility, safety and efficacy of the treatment of chronic symptomatic internal carotid artery long?segmental occlusion. Methods Fifty?one cases of chronic symptomatic internal carotid artery long?segmental occlusion (arterial occlusion more than 2 anatomical segments) who were treated with hybrid surgery (plaque located at the carotid sinus) or endovascular revascularization (plaque located at the distal end of the internal carotid artery occlusion) from May 2015 to May 2018 were reviewed. Recanalization, perioperative complications, stroke events, and reocclusion events during the follow?up period were recorded. Results The occlusion was recanalized successfully in 45 of 51 patients (88.2%, 45/51), 6 patients failed because the guidewire could not cross the distal arterial occlusion. And the technical success rate was 96.0% (24/25) in hybrid surgery and 80.8% (21/26) in endovascular revascularization. Perioperative complications occurred in 2 patients who underwent combined endovascular treatment. One patient had a small branch embolism due to intraoperative thrombus shift, and 1 patient had large area cerebral infarction. The complications occurred in 2 patients who underwent thybrid surgery, including 1 case of internal carotid cavernous fistula and 1 case of acute reocclusion of internal carotid artery. Forty?four patients with successful operation received clinical follow?up, with the median follow?up time of 24 months (7-43 months). No recurrent stroke and death occurred during the follow?up period. Clinical symptoms were improved in 34 cases. Totally 44 patients received imaging follow?up, and during the median imaging follow?up time of 8 month (4-28 months), 6 cases had reocclusion, and 2 cases had restenosis. Conclusion The treatment of chronic symptomatic internal carotid artery long?segmental occlusion is technically feasible and safety with good short?term efficacy. However, its exact efficacy remains to be confirmed by long?term follow?up studies with large samples.

Hepatocellular carcinoma (HCC) is one of the malignant tumors with the highest morbidity and mortality in the world. The morbidity and mortality of HCC are increasing every year. Liver cancer is a serious threat to public health in China and the death rate of patients with liver cancer in China is the highest in the world. Beyond surgery, chemotherapy and radiotherapy, immunotherapy is an emerging treatment for cancer, which could control and kill tumor cells by relieving the inhibitory status of immune cells in the tumor microenvironment and activating the immune function of the body. Immune checkpoint inhibitors, adoptive immunotherapy and tumor vaccine are the major treatments of immunotherapy. Compared with traditional therapy methods, immunotherapy could enhance immune function, delay tumor progression, prolong the survival time of patients, and becomes a hotspot in the basic and clinical cancer research. This article reviews the research progress of immunotherapy for liver cancer.

Objective To evaluate the feasibility of transvenous embolization treatment for cerebral arteriovenous malformations(bAVM). Methods From November 2016 to April 2017, the information of 6 patients with brain arteriovenous malformation in our center accepting the intravenous radical embolization were collected, who were ruptured bAVM, bAVM with a single drainage vein, not suitable for surgery confirmed by neurosurgeon consultation or explicitly refused craniotomy. The modified Rankin Scale score of five patients were smaller than three before treatment.The location of draining vein flowing venous sinus was shown by rotational DSA and 3D reconstructed images.A liquid embolic agent was injected via Sonic catheter to completely embolism the brain arteriovenous malformation under controlling blood pressure and blocking the blood provisionally.The perioperative complications and modified Rankin Scale score were observed and recorded 30 days after treatment. Results The transvenous embolization treatment was successfully performed in six patients with 7 embolization procedures.There were no definite operation-related complications. the mRS of all cases were ≤1 within 30 days after operation. Conclusion The embolization technique via the internal jugular vein is feasible for bAVM patients with a single drainage vein,while the long-term outcome need more evaluations.

Objective To explore the feasibility,safety and effect of endovascular revascularization for chronic long segment internal carotid artery occlusion. Methods The cases of chronic long segment internal carotid artery occlusion who were treated by endovascular revascularization in our center from May 2015 to April 2017 were reviewed. Eleven cases met the inclusion criteria:the duration of the occlusion was more than three weeks and the segment of the occlusion was beyond the petrosal segment of internal carotid arteries from the initial segment. All of the cases had the related symptoms and had declining cerebral perfusion. The analysis index included:baseline information,radiological information,perioperative results, clinical follow-up and imaging follow-up. The imaging follow-up index were the re-stenosis or re-occlusion of the revascularized artery. Results The occlusion was recanalized successfully in 9 of 11 patients,the two procedures were abandoned after repeated attempts and the guide wire could not reach the true lumen when navigating in the cavernous segment. Six cases of the nine successfully recanalized cases accepted perfusion-weighted imaging scan. Cerebral perfusion of all the cases were improved. Thrombus shifting was observed in one case and occluded a subbranch,mechanical thrombectomy was performed successfully,the case was recovered well without sequela. No symptomatic stroke or death was happened in the perioperative period. All of the nine cases who successfully recanalized acquired clinical follow-up,median follow-up time was ten months(4—28 months). No ischemic stroke and death happened after the procedures. Seven of nine cases improved in the clinical symptoms. Five cases accepted the imaging follow-up. The meantime was six months. No re-occlusion was happened. Conclusions Endovascular revascularization for chronic long segment internal carotid artery occlusion is feasible,safe,and short-term effective. More clinical research is needed to verify the long-term effect.
