Objective Taking a tertiary Traditional Chinese Medicine(TCM)hospital in Beijing as an example,it explores the differences in service quality perception among medical providers in Internet-based diagnostic services,aiming to provide robust support for the digital transformation of TCM medical services.Methods A questionnaire survey was conducted among 145 doctors who had diagnostic privileges on the Internet hospital platform of a certain hospital in September 2024.The survey focused on doctors'perceptions and satisfaction differences between online and offline medical service quality.Data processing and analysis were performed using EXCEL and SPSS 26.0 software,including descriptive analysis,reliability and validity tests,and rank-sum tests.Results 66.34%of the doctors recognized the Internet hospital platform established by the hospital,but the average satisfaction score(3.86)was still lower than that of offline outpatient service platforms,which was 4.59.Especially in the three dimensions of diagnosis and treatment,quality assurance,and psychosocial care,the perception of online service quality was significantly lower than that of offline services(P＜0.001).Despite this,82.76%of doctors were still inclined to recommend the internet-based diagnostic model to suitable patients.Conclusion Internet hospitals should establish a refined and intelligent platform system and rigorous service quality control standards to optimize doctors'online consultation processes.Comprehensive training for online consulting doctors should be strengthened.By improving the service quality of medical providers,the integration of online and offline services can be promoted to meet patients'demands for high-quality medical services.

This report presents the management of a critically ill 36-year-old woman diagnosed with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph +ALL) at 28 weeks of gestation. The patient rapidly deteriorated, developing disseminated intravascular coagulation (DIC) , diffuse alveolar hemorrhage (DAH) , septic shock, and multi-organ dysfunction, necessitating admission to the hematological intensive care unit. Given her critical condition and advanced pregnancy, a chemotherapy-free induction regimen comprising imatinib and dexamethasone was initiated, alongside comprehensive supportive measures, including mechanical ventilation, continuous renal replacement therapy (CRRT) , broad-spectrum antibiotics, and high-dose corticosteroids. During treatment, intrauterine fetal demise occurred, and a stillborn was delivered following obstetric intervention. With aggressive treatment, the patient's respiratory failure, DIC, and DAH gradually resolved, and she achieved complete remission. She subsequently received consolidation chemotherapy, CAR-T cell therapy, and allogeneic hematopoietic stem cell transplantation, achieving sustained complete molecular remission on long-term follow-up. This case demonstrates that for critically ill pregnant patients with Ph + ALL, a chemotherapy-free regimen of targeted therapy and corticosteroids, when combined with intensive supportive care, is a safe and effective approach that may offer a therapeutic option for similar cases.

Peri-implant diseases are inflammatory diseases in the spectrum of oral diseases, which are caused by the dysbiosis of peri-implant flora and the imbalance between microorganism and host. Peri-implant diseases are divided into two types: peri-implant mucositis and peri-implantitis. The diagnostic definition of peri-implant mucositis is based on presence of peri-implant signs of inflammation (redness, swelling, line or drop of bleeding/suppuration following probing) and no additional bone loss following initial healing. The clinical definition of peri-implantitis is based on not only the presence of peri-implant signs of inflammation but also radiographic evidence of bone loss following initial healing. Peri-implant diseases, like periodontitis, have clear etiology, histopathological features, clinical manifestations, and current international consensus diagnostic criteria. This article provides an overview of the etiology, histopathological features, key points of examination and diagnosis, prevention and non-surgical treatment, and surgical treatment of peri-implant diseases. The aim is to raise the awareness of dentists, especially those who specialize in oral implantology and restoration, to have a concept of periodontal and implant health, master the basic theoretical knowledge and prevention and treatment methods of peri-implant diseases, and also inform patients to control plaque and maintain their oral health.

Peri-implant disease is an oral disease that occurs with dental implant treatment. It is an inflammatory disease of peri-implant tissues caused by plaque biofilm, which can be divided into peri-implant mucositis and peri-implantitis. Peri-implant mucositis is limited in the soft tissues surrounding the implant and can be relieved through effective treatment. However if untreated, the inflammation can affect the bone around the implant and develop into peri-implantitis. Progressive resorption of supporting bone can ultimately lead to loss of osseointegration, which is the main cause of implant failure. There is a high incidence of peri-implant disease worldwide, which has become an increasingly serious public health problem. Prevention and supportive treatment of peri-implant disease is an important aspect of promoting oral health and deserves the attention of all dental professionals. This article combines literature review and relevant researches conducted by our research group in the past 15 years to introduce the control of risk factors, prevention, and supportive treatment of peri-implant disease. The aim is to raise the great attention of dentists, who engaged in oral implantation and restoration, to peri-implant and periodontal health, and master the prevention and supportive treatment methods of peri-implant disease.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective:To examine the clinical features and genetic profiles of patients with thyroid peroxidase(TPO) gene mutations and provide diagnostic guidance for clinicians.Methods:A retrospective review of four patients with TPO mutations treated at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, from January 2014 to December 2023. Data on demographics, clinical manifestation, genotypes, treatment, and prognosis of these patients were analyzed.Results:Two males and two females, aged 13 to 27 years at diagnosis, presented with goiter as the initial symptom, with three cases menifesting during puberty. Laboratory findings showed mildly elevated or upper-limit-normal serum thyroid-stimulating hormone(TSH) levels, significantly increased free triiodothyronine/free thyroxine(FT 3/FT 4) ratios, and elevated thyroglobulin(TG) levels. Genetic testing revealed compound heterozygous pathogenic or likely pathogenic TPO mutations. Despite regular levothyroxine(L-T 4) therapy, goiter persisted. Three patients required thyroidectomy due to cosmetic or compressive symptoms, with pathology showing follicular hyperplasia. Conclusion:TPO mutations are characterized by adolescent-onset goiter, elevated FT 3/FT 4 ratios, and normal to high TSH. Genetic testing confirms the diagnosis. L-T 4 offers limited improvement, and surgery is often needed.
