Social robots play an important role in the field of medical companionship， providing services such as companion communication， drug monitoring， and rehabilitation guidance for the elderly and other subjects. However， social robots also pose the risk of deceiving medical users. Although certain forms of social robots’ deception can be used for therapeutic purposes， unethical deception can have adverse consequences for patients， doctors， and even society. These risks include causing patients to develop attachment disorders， violating their privacy， endangering their health， and even undermining the credibility of the healthcare system. Faced with the deception problem of social robots， starting from relational theory， medical artificial intelligence developers can conduct ethical regulation from the following two paths. First， social robots should be ethically programmed， including embedding programs for limiting benevolent lies， implementing informed consent principles， and ensuring information accuracy. Second， the deceptive behaviors of social robots should be controlled， requiring developers to take full-process supervision responsibility， design medical social robots that can supervise each other， and participate in formulating quality standards and evidence mechanisms for deception issues.

Objective:Explore the clinical diagnosis and treatment strategies of recurrent multiple chondritis in children with airway involvement as the main cause. Methods:From June 2021 to May 2023, five children with relapsing polychondritis were admitted to our department, all of whom met the Damiani criteria. Tracheotomy was performed in all five patients. Endoscopy indicated subglottic stenosis, with one case classified as grade Ⅲ and four cases as grade Ⅳ according to the Myer-Cotton classification. Enhanced CT scans of the head and neck showed fixed lumen narrowing and stenosis, including thickening of the soft tissue in the laryngeal cavity and partial absorption of the laryngotracheal cartilage anterior wall. In one patient, tracheal wall thickening and deformation with stenosis and calcification involved the posterior tracheal wall. One patient underwent "laryngeal tracheal reconstruction with hyoid graft, T-tube implantation, and bioabsorbable corticosteroid-eluting stent implantation", while three patients underwent "balloon dilatation, T-tube implantation, and bioabsorbable corticosteroid-eluting stent implantation" . Follow-up was performed every two months after the initial surgery, and three bioabsorbable corticosteroid-eluting stents were placed on the upper left, upper right, and lower T-tube, respectively, during this time. The entire follow-up period was six months. Results:All the 5 cases were in the outpatient department, of which 1 case had been extubation, 3 cases were still in the outpatient follow-up, and the remaining 1 case was still being treated in the rheumatology and immunology department due to poor control of the primary disease. Conclusion:In relapsing polychondritis children with airway involvement, tracheotomy could be used to quickly improve the symptoms of dyspnea in the disease progression. In the stable stage of the disease, the surgical method of 'Balloon dilatation + T-tube implantation + Bioabsorbable corticosteroid-eluting stents implantation' was adopted to reduce the secondary injury caused by surgical trauma as much as possible and improve the survival and quality of life of the children.

Objective:To explore the clinical manifestations, diagnosis, treatment, pathological types and prognosis of primary cervical neuroblastoma in children. Methods:The clinical data of 11 children with primary cervical neuroblastoma admitted to the Department of Otolaryngology and Head and Neck Surgery at Shanghai Children's Hospital from April 2015 to April 2022 were retrospectively analyzed. The clinical characteristics, imaging findings, pathological types, treatment methods, and outcomes of these 11 patients were examined in conjunction with a review of the literature. Results:The cohort of 11 neuroblastoma patients ranged in age from 28 days to 88 months （median age: 24 months）, including 3 males and 8 females. Among the 11 patients, 4 had tumors located in the carotid sheath area, 4 in the cervical space, and 3 in the parapharyngeal and retropharyngeal spaces. The clinical manifestations primarily included painless cervical masses and laryngeal stridor. There were 3 cases of primary cervical tumors with cervical lymph node metastasis and 1 case with bone marrow metastasis. Pathological findings revealed neuroblastoma in 8 cases and ganglionic neuroblastoma in 3 cases. In this group, 7 patients underwent surgery combined with chemotherapy, 2 patients received surgery combined with chemoradiotherapy, and 2 patients underwent surgery alone. Surgical resection was performed via a cervical approach in 7 cases, while 3 cases were treated using a transoral endoscopic approach. Additionally, one patient underwent a transoral endoscopic approach initially and a cervical approach subsequently. All patients completed their treatment and were followed up regularly, with follow-up durations ranging from 6 to 79 months （median: 34 months）. Nine patients achieved complete remission, 2 patients achieved partial remission, and none experienced disease progression. Conclusion:Primary cervical neuroblastoma exhibits a high degree of heterogeneity and presents at a younger age, primarily with cervical masses. Compared to external approaches, endoscopy-assisted transoral resection of parapharyngeal tumors offers advantages such as reduced damage to surrounding tissue and no visible neck scars, providing a new method for clinical treatment. Regular follow-up is essential for children with neuroblastoma, along with the establishment of specific disease management protocols and comprehensive care to improve survival quality.

Objective:This aims to investigate the diagnostic and evaluative value of MRI for lymphatic malformations in the head, neck, and facial regions of children. Methods:A retrospective analysis was conducted on the MRI imaging data of 31 cases of head, neck, and facial lymphatic malformations in children admitted to the Department of Otolaryngology, Head and Neck Surgery, Children's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, from January 2022 to January 2024. Results:The MRI images of this group of cases primarily displayed irregular morphology（80.6%, 25/31）, thin-walled cysts（80.6%, 25/31）, and compression of surrounding tissues. The boundaries were clear（100%, 31/31）, with characteristics of invasive and drill-like growth（93.5%）. The cyst walls or internal septa exhibited high signal intensity on T1WI, low signal intensity on T2WI, and mild to moderate enhancement（100%）. The contents of the cysts showed low signal intensity on T1WI, high signal intensity on T2WI, and no enhancement（35.5%, 11/31）. Mixed signals with varying degrees of enhancement were observed in 20 cases（64.5%）. There were 29 cases of multilocular cysts（93.5%, 29/31）, and 11 cases of fluid-fluid levels（35.5%）. The MRI diagnostic accuracy for this group of cases was 100%. Conclusion:Lymphatic Malformations of head, neck and facial region in children have very characteristic features on MRI, such as typical thin wall, clear boundaries, irregular shapes, invasive growth, no enhancement, multilocular cystic masses, fluid-fluid level, etc. Furthermore, it is more appropriate for children with lymphatic malformations owing to its non-radiation and non-invasive benefits. Diagnosing lymphatic malformations in the head, neck, and facial region in children should begin with this.

The idea of disease prevention runs through the traditional medical diagnosis and treatment system,and also plays an important role in the prevention and treatment of gastric precancerous lesions.This article organically combines disease differentiation,syndrome differentiation,symptom differentiation,and constitution differentiation to form a four in one diagnosis and treatment model.Disease differentiation means identifying the name of the disease and grasping the progression stage of the disease;syndrome differentiation means combining the macroscopic and microscopic aspects to accurately grasp the pathogenesis;symptom differentiation means identifying complications and clinical problems that need to be solved urgently;constitution differentiation means predicting syn-drome type bias and disease development.This model not only enables systematic diagnosis and treatment of gastric precancerous le-sions,but also provides targeted diagnosis and treatment plans for patients,with the characteristics of comprehensiveness,full process,and personalization.Therefore,combining the four in one diagnosis and treatment model of disease differentiation-syndrome differentia-tion-symptom differentiation-constitution identification with the disease prevention theory is conducive to the early detection of gastric precancerous lesions,timely tracking of the progress of the lesions,and the adoption of correct,comprehensive,and full-process inter-vention methods to reverse gastric precancerous lesions,which can play a positive role in the diagnosis,treatment,and prevention of gastric precancerous lesions.

Background Quartz dust cannot be degraded in the lungs, and inhalation of a large amount of quartz dust in the occupational production process will lead to the occurrence of pulmonary fibrosis, and then develop into silicosis. In recent years, studies have found that exosomes may be involved in the pathogenesis of fibrotic diseases by carrying microribonucleic acid (miRNA), but the mechanism of their actions in silicosis still needs to be studied. Objective To investigate the role of exosome-derived miRNA-21-5p/mothers against decapentaplegic homolog 7 (Smad7) in quartz dust-induced pulmonary fibrosis in rats. Methods Twenty-four healthy male SD rats were randomly divided into four groups (six rats in each group): control 4-week group, control 16-week group, quartz 4-week group, and quartz 16-week group. At the beginning of the experiment, 1 mL of quartz suspension (50 mg·mL⁻¹) and 1 mL of normal saline were injected into the trachea of rats in the quartz group and the control group, respectively, by means of one-time non-exposure intratracheal dust staining. Alveolar lavage was performed at the 4th and 16th weeks after dust staining, the exosomes in lavage solution were extracted by polyethylene glycol (PEG) precipitation, morphological identification was conducted by transmission electron microscopy (TEM), particle size of exosomes was detected by nano-tracking analysis (NTA), and the marker proteins CD9 and CD63 of exosomes were detected by Western blotting (WB). The expression of miRNA-21-5p in exosomes was determined by reverse transcription polymerase chain reaction (RT-PCR). The degree of lung tissue injury and fibrosis was observed by hematoxylin-eosin staining (HE) and Masson staining. The collagen content of lung tissue was detected by hydroxyproline (HYP) method. The expression of Smad7 protein in lung tissue was detected by WB. Results The results of pathological staining showed that compared with the control group, lung inflammatory cell infiltration, alveolar wall thickening, and collagen increase were observed after 4 weeks of dusting, and collagen deposition and silicon nodules appeared after 16 weeks of dusting. Compared with the control group, the expression level of HYP in the lung tissue of the quartz group was increased after 4 weeks and 16 weeks of dust staining (P<0.05). Transmission electron microscopy showed that exosomes were saucer-shaped, and the average particle size of exosomes was 95.8 nm by NTA. Positive expression of exosome marker proteins CD9 and CD81 was found by WB. Compared with the control group, the expression of exosome-derived miRNA-21-5p in alveolar lavage fluid in the quartz group increased in the 4th week and the 16th week (P<0.05), and the expression of Smad7 protein in lung tissue decreased (P<0.05). Conclusion Exosome-derived miRNA-21-5p and Smad7 may be involved in the mechanism of quartz dust-induced pulmonary fibrosis in rats.
