Metabolic dysfunction-associated fatty liver disease （MAFLD） has become one of the most prevalent chronic liver diseases worldwide， posing a serious challenge to public health. In this context， the integration of artificial intelligence （AI）， especially intelligent diagnosis and treatment and digital health interventions based on machine learning， can break through the limitations of traditional methods， realize efficient screening of multi-dimensional data such as key genes， biomarkers， and biochemical metabolites， and achieve revolutionary breakthroughs in risk prediction， subtype identification， and therapeutic effect assessment for MAFLD. This article systematically reviews the ground-breaking application of machine learning models in driving the innovation of clinical diagnosis and precise risk prediction of MAFLD， conducts a comprehensive comparative analysis of digital health practice cases of MAFLD in China and globally， and deeply analyzes their advantages and limitations in terms of research subjects， interventions， and management team. Studies have shown that the deep integration of digital health and long-term management of MAFLD is becoming the key engine driving the transformation of disease management modes towards an intelligent， individualized， and precise era， but there are various ethical and technical issues that need to be addressed urgently.

Objective To explore the effect of SGLT2 inhibitor(SGLT2i)Dagaglipzin(Dap)on mitochondrial autophagy in cardiomyocytes in diabetic cardiomyopathy(DCM)by regulating mitochondrial membrane transporter TOM20.Methods H9C2 cardiomyocytes cultured in vitro were divided into normal control(Con)group,HG+PA group,knockout TOM20(HG+PA+siTOM20)group,knockout control(HG+PA+siNC)group,Dap intervention(HG+PA+Dap)group,and solvent control(HG+PA+DMSO)group.The expression of TOM20 was predicted by RNA-seq second-generation sequencing in HG+PA group.The expression of TOM20 and mitochondrial autophagy related proteins was detected by Western blot,the mitochondrial membrane potential was measured by immunofluorescence staining,and the mitochondrial autophagy level was evaluated by transmission electron microscopy.Results Compared with Con group,protein expressions of TOM20 and P62 were increased(P<0.05),while protein expressions of ULK1,Parkin,Beclin1 and LC3-B were decreased(P<0.05),mitochondrial membrane potential was destroyed,the number of mitochondrial autophagosomes was reduced,and autophagy activity was inhibited in HG+PA group.Compared with HG+PA+siNC group and HG+PA+DMSO group,the protein expressions of TOM20 and P62 were decreased(P<0.05),while the protein expressions of ULK1,Parkin,Beclin1 and LC3-B were increased(P<0.05),the damage of mitochondrial membrane potential decreased,the number of mitochondrial autophagosomes increased,and the inhibition of autophagy activity reversed in HG+PA+siTOM20 and HG+PA+DAPA groups.Conclusions SGLT2 inhibitors appear to partially restore mitochondrial function in diabetic cardiomyopathy by suppressing TOM20 expression,potentially through activation of mitochondrial autophagy.

Objective To explore the mechanism of TubA in the treatment of ulcerative colitis in mice,and to lay a foundation for the treatment strategy of ulcerative colitis.Methods Twenty C57BL/6 mice aged 6-8 weeks were randomly divided into 4 groups(n=5):the control group drank pure water every day,the model group and the treatment groups drank 3％dextran sulfate sodium(DSS)every day,and the treatment groups were injected with 10 mg/kg TubA and 20 mg/kg TubA every day from the third day,respectively.The weight changes of mice in all groups were recorded.Nine days later,the serum of mice was collected,and the expression levels of inflammatory factors IL-1β,IL-6 and IL-10 in serum were detected by ELISA.HE staining was used to observe the pathological changes of the mouse colon.The expression of myeloperoxidase(MPO)was detected by immunohistochemistry,the mRNA levels of inflammatory factors IL-1β,IL-6 and IL-10 were detected by RT-qPCR,and the expressions of GPX4 and FTH were detected by immunohistochemistry.The mRNA and protein expression levels of GPX4,GCLM,FTH,Nrf2,Keap1 and HO-1 in colon tissues were detected by RT-qPCR and Western blotting.Results Compared with the control group,the body weight and colon length of the model group decreased significantly.HE staining showed that inflammatory cells infiltrated the mucosa and submucosa of colon tissue,goblet cells were lost and crypt structure disordered and disappeared.Immunohistochemistry showed that the expression of MPO and FTH proteins were significantly increased,while the expression of GPX4 protein was significantly decreased(P＜0.05).The mRNA and protein expression levels of IL-1β and IL-6 were significantly increased,while the mRNA and protein expression levels of IL-10 were significantly decreased(P＜0.05).The mRNA and protein expression levels of FTH,Nrf2 and HO-1 were significantly increased,while the mRNA and protein expression levels of GPX4,GCLM and Keap1 were significantly decreased(P＜0.05).After TubA treatment,compared with the model group,all these changes mentioned above suppressed(P＜0.05).Conclusion TubA may reduce ulcerative colitis symptoms by inhibiting ferroptosis,providing new ideas for the treatment of ulcerative colitis.

Metabolic associated fatty liver disease(MAFLD)is a type of fatty liver disease associated with systemic metabolic disorders,and its prevalence has been increasing year by year,becoming a major challenge to global public health.The development of MAFLD is associated with various factors,including obesity,dyslipidemia,diabetes and other factors.Excessive body fat,particularly increased visceral adiposity,contributes to hepatic fat accumulation.Abnormal blood lipid levels can also disrupt liver fat metabolism.The risk of MAFLD in patients with diabetes is greatly increased due to insulin resistance and other problems.Dietary interventions are considered an effective strategy for the prevention and treatment of MAFLD.In recent years,several dietary patterns,such as low-carbohydrate diets,intermittent fasting,and the Mediterranean diet,have been applied in clinical practice.Their primary mechanisms include reducing oxidative stress,regulating gut microbiota,and inducing fat autophagy.However,the responses to different dietary patterns vary among individuals due to differences in genes,lifestyle,and disease severity.Therefore,systematically evaluating the effects and mechanisms of these dietary patterns in the prevention and treatment of MAFLD has significant clinical importance.This review compares the effects of different dietary patterns on improving liver function,hepatic fat content,blood glucose,and lipid levels,and analyzes their underlying mechanisms of intervention,to explore how to select personalized dietary strategies based on individual differences.It is intended to provide new insights for the precise prevention and treatment of MAFLD,thereby improving patients' outcomes and alleviating the burden on public health.

Objective To evaluate the clinical application of CT-guided coaxial needle biopsy in pancreatic puncture-cutting biopsy via adipose tissue space.Methods The clinical data of 30 patients,who received CT-guided pancreatic coaxial needle biopsy via adipose tissue space at the Pingdu Hospital Area of Affiliated Hospital of Qingdao University of China from June 2021 to April 2024,were retrospectively analyzed.The patients included 20 males and 10 females with a mean age of(65.1±8.7)years.The lesions were located in the pancreatic head(n=7),pancreatic neck(n=4),pancreatic body(n=7),pancreatic tail(n=10)and uncinate process(n=2).Under CT guidance,a 17 G co-axial guiding needle was inserted to establish a puncture pass through adipose tissue space,then an 18 G biopsy needle was used to make tissue sampling.A total of 32 procedures of pancreatic puncture-cutting biopsy were performed,two of these patients received two times of biopsy.After sampling,a self-made blocking agent(a mixed liquid of gelatin sponge particles and snake venom hemagglutinin),was used to occlude the puncture channel so as to prevent complications such as bleeding,pancreatic leakage,needle tract implantation metastasis,etc.Results A total of 32 procedures of pancreatic puncture-cutting biopsy with coaxial guiding needle via adipose tissue space were performed,including two patients who received two times of biopsy.The success rate of puncturing was 100％(32/32),the success rate of sampling was 93.8％(30/32),and the accuracy of sampling was 93.8％(30/32).No serious puncture-related complications occurred in all patients.Conclusion CT-guided pancreatic coaxial needle biopsy via adipose tissue space is clinically safe,accurate in sampling and minimally-invasive.This interventional diagnostic technique is worth applying in clinical practice.

With the popularization of 5G communication technology and the continuous upgrade of robot-assisted surgery system,telesurgery has developed rapidly.However,there are few of reports about this technique in single-port laparoscopic gynecological surgery.On April 19,2024,the surgeons at the Second Affiliated Hospital of Naval Medical University in Shanghai successfully implemented robot-assisted single-port laparoscopic bilateral adnexectomy for a patient who was admitted to the Naval Hospital of the Eastern Theater Command in Zhoushan,Zhejiang Province through 5G communication technology.The operation time was 90 min,intraoperative bleeding was 20 ml,and no intraoperative complications occurred.There were no adverse events caused by robots such as robot system failure and instrument failure,or adverse events caused by remote communication such as network interruption and network attack.Intraoperative user datagram protocol(UDP)real-time monitoring data showed an average delay of 108 ms(range,105-111 ms)and a packet loss rate of 0.04%.The surgeons had a slight sense of delay when the operation amplitude was too large.There was no obvious stalling which affected the process of the operation.The patient was able to move around on the first day after surgery,and the catheter was removed.No postoperative complications occurred.The patient was discharged from the hospital on the second day after surgery.Postoperative pathological results revealed left fallopian tube ovarian serous cystadenofibroma,fallopian tubal tissue;right fallopian tube ovarian,sent for examination as ovarian and fallopian tube tissue.There were no complaints of discomfort during reexamination one month after surgery,and the umbilical incision healed well.This case is an attempt of telesurgery in the field of gynecology,and provides experiences for the further development of this technique.

Traditional Chinese medicine(TCM)features complex compatibility mechanisms involving multi-component,multi-target,and multi-pathway interactions.This study presents an interpretable graph artificial intelligence(GraphAI)framework to quantify such mechanisms in Chinese herbal formulas(CHFs).A multidimensional TCM knowledge graph(TCM-MKG;https://zenodo.org/records/13763953)was constructed,integrating seven standardized modules:TCM terminology,Chinese patent medicines(CPMs),Chinese herbal pieces(CHPs),pharmacognostic origins(POs),chemical compounds,biological targets,and diseases.A neighbor-diffusion strategy was used to address the sparsity of compound-target associations,increasing target coverage from 12.0％to 98.7％.Graph neural networks(GNNs)with attention mechanisms were applied to 6,080 CHFs,modeled as graphs with CHPs as nodes.To embed domain-specific semantics,virtual nodes medicinal properties,i.e.,therapeutic nature,flavor,and me-ridian tropism,were introduced,enabling interpretable modeling of inter-CHP relationships.The model quantitatively captured classical compatibility roles such as"monarch-minister-assistant-guide",and uncovered TCM etiological types derived from diagnostic and efficacy patterns.Model validation using 215 CHFs used for coronavirus disease 2019(COVID-19)management highlighted Radix Astragali-Rhi-zoma Phragmitis as a high-attention herb pair.Mass spectrometry(MS)and target prediction identified three active compounds,i.e.,methylinissolin-3-O-glucoside,corydalin,and pingbeinine,which converge on pathways such as neuroactive ligand-receptor interaction,xenobiotic response,and neuronal func-tion,supporting their neuroimmune and detoxification potential.Given their high safety and dietary compatibility,this herb pair may offer therapeutic value for managing long COVID-19.All data and code are openly available(https://github.com/ZENGJingqi/GraphAI-for-TCM),providing a scalable and inter-pretable platform for TCM mechanism research and discovery of bioactive herbal constituents.

Objective To explore the diagnosis and treatment experience of malignant peritoneal mesothelioma by analyzing the clinical characteristics of patients with single center peritoneal mesothelioma.Methods Retrospec-tively analyze the clinical data,including age and treatment regimens,of 99 patients with malignant peritoneal mes-othelioma admitted to Peking Union Medical College Hospital from June 2012 to July 2023.Kaplan-Meier for surviv-al analysis and Logistic and Cox regression were applied to assess the impact of factors like age and treatment regi-mens on survival time.Results The median age of diagnosis for 99 patients with peritoneal mesothelioma was 56 years,of which 82 were pathologically diagnosed.Among them,38 cases(51.4%)underwent tumor cell reduction surgery,and 57 cases(77.0%)underwent systemic or local treatment.The median survival time for all patients was 43 years.The age of diagnosis may affect the prognosis of patients with malignant mesothelioma,and those aged≥65 at the time of diagnosis have a worse prognosis.Conclusions Malignant peritoneal mesothelioma is a rare but invasive malignant tumor with a poor prognosis.There is still a need to develop novo drugs and comprehensive treat-ment strategies.

To address the limitations of traditional minimally invasive thermal ablation technology such as poor conformability, carbonization and electromagnetic radiation, this paper proposes a steam thermal ablation technology that uses saturated steam internal energy to replace the traditional electromagnetic radiation energy. Through the steam thermal ablation system and the steam thermal ablation needle designed based on simulation, the ex vivo pig liver experiments were carried out. The results have the characteristics of the maximum ablation axis ratio (short diameter / long diameter) and non-carbonization with the same type of thermal ablation technology. Based on the near-infrared light, in this paper the curative effect of the reduced scattering coefficient of the steam thermal ablation results was evaluated. The reduced scattering coefficients of the coagulation area all exceeded 16, reaching the completely damaged state, which verified that the steam thermal ablation can effectively inactivate the tumor cells.
