Objective:To review the diagnosis, treatment and quality of life of patients with primary immune thrombocytopenia (ITP) in seven medical centers in some areas of Hubei Province.Methods:A retrospective analysis was conducted on age, disease course, symptoms, diagnosis, and treatment status (including testing items, drug selection, and adverse reactions) of patients with ITP in seven medical centers in Hubei Province from January 2020 to December 2022. An online survey was conducted on the quality of life of patients using the ITP Patient Assessment Questionnaire (ITP-PAQ) .Results:Among the 1033 patients, those with newly diagnosed, persistent, and chronic ITP accounted for 39.8%, 19.1%, and 41.1%, respectively. Most patients exhibit varying degrees of bleeding. Regarding treatment, corticosteroids and thrombopoietin drugs are the most commonly chosen treatment drugs for ITP, and the adverse reactions to treatment mainly include diarrhea, liver dysfunction, and thrombosis. The ITP-PAQ survey of 125 patients revealed that ITP significantly impairs their life quality. Patients with ITP scored significantly lower in fatigue, sleep, fear, exercise, work, and social aspects.Conclusion:A relatively high proportion of patients with ITP progressed to the chronic phase. Corticosteroids and thrombopoietin drugs are the two main treatment drugs for ITP patients. The quality of life of patients with ITP is significantly reduced in multiple dimensions.

Microglial functions are linked to Ca²⁺ signaling, with endoplasmic reticulum (ER) calcium stores playing a crucial role. Microglial abnormality is a hallmark of Alzheimer's disease (AD), but how ER Ca²⁺ receptors regulate microglial functions under physiological and AD conditions remains unclear. We found reduced ryanodine receptor 2 (Ryr2) expression in microglia from an AD mouse model. Modulation of RyR2 using S107, a RyR-Calstabin stabilizer, blunted spontaneous Ca²⁺ transients in controls and normalized Ca²⁺ transients in AD mice. S107 enhanced ATP-induced migration and phagocytosis while reducing ramification in control microglia; however, these effects were absent in AD microglia. Our findings indicate that RyR2 stabilization promotes an activation state shift in control microglia, a mechanism impaired in AD. These results highlight the role of ER Ca²⁺ receptors in both homeostatic and AD microglia, providing insights into microglial Ca²⁺ malfunctions in AD.

Objective:To evaluate the practical effectiveness of a one-to-one mentorship-based short-term training model for senior medical professionals in clinical, teaching, research, and management dimensions based on the reaction and learning levels of the Kirkpatrick model, and to explore its application value.Methods:A total of 109 physicians and their 109 mentors who participated in the senior medical professional training program at The First Affiliated Hospital of Sun Yat-sen University from June 2023 to May 2024 were included. The one-to-one mentorship teaching method was implemented. Data were collected through self-assessment questionnaires and mentor evaluation forms to analyze satisfaction, proficiency, competency improvement, and training effectiveness and their correlations.Results:Valid feedback forms were collected from 100 physicians and 100 mentors. At the reaction level, the satisfaction of trainees was high for mentors (99.00%, 99/100) and training content [clinical: 98.96%(95/96), teaching: 93.75%(15/16), research 85.71%(12/14), management: 100.00%(24/24)]. At the learning level, trainee self-assessed and mentor-evaluated proficiency exceeded 75.00% across all dimensions except research. Significant improvements in clinical, teaching, research, and management competencies were reported by both trainees and mentors ( P<0.001). Notably, evaluations of clinical competency improvement showed strong consistency ( r s=0.37, P<0.001). Conclusions:The one-to-one mentorship-based short-term training model demonstrated positive effects in enhancing mentorship outcomes and excellent educational effectiveness in senior medical professionals. This model is recommended for implementation in similar hospitals for training senior medical professionals.

Fatal familial insomnia,an autosomal dominant prion disease,is rare.We reported the clin-ical symptoms,examination results,diagnosis,treatment,and prognosis of a patient who was diagnosed with fatal familial insomnia.Furthermore,we described the unique clinical manifestations that involuntary movements and laryngeal stridor were significantly correlated with postural changes,aiming to provide reference for the clini-cal diagnosis,treatment,and research of the disease in the future.

Primary central nervous system vasculitis(PACNS)is a vasculitic disorder affecting small to medium-sized blood vessels primarily in the central nervous system,involving the brain,spinal cord,and me-ninges.Tumor-like PNCAS,a rare subtype of PACNS,is often misdiagnosed as intracranial malignancy,and that with spinal cord involvement is even more uncommon.The lack of specific clinical symptoms and imaging manifestations poses a challenge to the diagnosis of PACNS.This report presents a case of tumor-like PACNS with spinal cord involvement based on the pathological evidence,aiming to enrich the knowledge about this condition.

Objective To analyze the clinical features of 17 patients with primary angiitis of the central nervous system(PACNS)and thus facilitate the early diagnosis and treatment,reduce the recurrence and mortal-ity,and improve the prognoses of this disease.Methods We collected the data of patients with PACNS diag-nosed by brain biopsy from January 2009 to June 2023 and analyzed their clinical presentations,laboratory and imaging manifestations,electrophysiological and pathological changes,and treatment regimens and prognosis.Results The 17 patients diagnosed with PACNS via brain biopsy included one child and 16 adults.The subtyp-ing results showed that 10,2,3,2,1,and 1 patients had tumorous,spinal cord-involved,angiography-posi-tive,rapidly progressive,hemorrhagic,and amyloid β-related PACNS,respectively.Eleven(64.7％)of the patients were complicated with secondary epilepsy.All the patients exhibited abnormal manifestations in head MRI,with 94.1％showing lesions with uneven enhancement around the lesions or in the leptomeninges.Mag-netic resonance angiography revealed large vessel abnormalities in 3 patients,and spinal cord involvement was observed in 2 patients.Histopathological typing revealed 7(43.7％)patients with lymphocytic vasculitis and 5(31.2％)patients with necrotizing vasculitis.Eleven patients were treated with glucocorticoids and cyclophospha-mide,which resulted in partial lesion disappearance and symptom amelioration in 6 patients upon reevaluation with head MRI after 3 months of maintenance therapy.Two,1,and 3 patients experienced rapid disease progres-sion,death,and recurrence within 1 year,respectively.Three patients showed insensitivity to hormonotherapy and residual disabilities.Two patients received rituximab after relapse and remained clinically stable during a fol-low-up period of 0.5-1 year.Conclusions Tumorous PACNS was more prone to epilepsy,mainly occurring in males.The most common histopathological type was necrotizing vasculitis,which responded to hormonotherapy and had favorable outcomes.Therefore,for the young patients with epilepsy and intracranial tumorous lesions,the possibility of PACNS should be considered.Spinal cord involvement in PACNS was often located in the thorac-ic and cervical cords,suggesting a poorer prognosis.Electromyography commonly revealed neural conduction ab-normalities in the anterior horn or roots,providing clues for differential diagnosis.For suspected spinal cord in-volvement,comprehensive electromyography is recommended.Rapidly progressive PACNS often presented infrat-entorial lesions,such as lesions in the pons and medulla,with a higher mortality rate.Hemorrhagic PACNS was rare,and a multifocal hemorrhagic lesion with enhancement in the intracranial region,particularly in young pa-tients,should raise suspicion.For the patients with recurrent or progressive disease,rituximab is a recommended therapeutic option.
