Autism Spectrum Disorder (ASD) is marked by early-onset neurodevelopmental anomalies, yet the temporal dynamics of genetic contributions to these processes remain insufficiently understood. This study aimed to elucidate the role of the Shank3 gene, known to be associated with monogenic causes of autism, in early developmental processes to inform the timing and mechanisms for potential interventions for ASD. Utilizing the Shank3B knockout (KO) mouse model, we examined Shank3 expression and its impact on neuronal maturation through Golgi staining for dendritic morphology and electrophysiological recordings to measure synaptic function in the anterior cingulate cortex (ACC) across different postnatal stages. Our longitudinal analysis revealed that, while Shank3B KO mice displayed normal neuronal morphology at one week postnatal, significant impairments in dendritic growth and synaptic activity emerged by two to three weeks. These findings highlight the critical developmental window during which Shank3 is essential for neuronal and synaptic maturation in the ACC.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

OBJECTIVE To explore the characteristics and influential factors of pharmaceutical clinic service demands， providing evidence for optimizing pharmaceutical service models and facilitating pharmaceutical service models of pharmacist role transformation. METHODS A cross-sectional survey design was adopted， and 410 outpatient participants were selected from Fudan University Shanghai Cancer Center through convenience sampling for questionnaire administration from February to May 2025. Kano model was applied to analyze the demand attributes of 25 pharmaceutical services， while questionnaires were used to assess patients’ awareness and demand status. Subgroup analyses were conducted based on key demographic variables such as gender， age， educational attainment， and economic burdens， to SACA- systematically examine the differences in Kano attribute classification among patients in each subgroup. RESULTS The awareness rate of pharmaceutical outpatient services among patients was only 14.63%， yet those who were aware demonstrated a significantly higher demand rate for such services compared to those who were unaware （P＜0.001）. The demand for pharmaceutical clinic services exhibited a hierarchical characteristic： twelve items were identified as attractive attributes （e. g.， providing suggestions for more affordable treatment options， offering online consultation services， etc.）， five items as expected attributes （e.g.， having a good attitude and being able to patiently answer your questions， etc.）， three items as must-have attributes （e.g.， providing guidance on medication dosage and usage， providing guidance on medication precautions， etc.）， five items as indifferent attributes （e.g.， providing treatment plan recommendations based on the patient’s condition）. There were zero items classified as reverse attribute. Subgroup analysis revealed that female patients showed greater concern for “neat and clean attire of medical staff” than male patients （P＜0.001）； patients under 60 years of age demonstrated stronger demand for “providing treatment plan recommendations based on patients’ conditions” compared to patients aged 60 or above （P＝0.016）； those with below high school education placed greater emphasis on “providing guidance on medication precautions” compared to those with a high school education or above （P＝0.011）； patients with lower economic burdens exhibited stronger preferences for “neat and clean attire of medical staff ” （P＝0.002）. CONCLUSIONS The public awareness rate of pharmaceutical clinic services is considerably low； however， those who are aware of such services demonstrate significantly higher demand. The medication safety-related services and convenience-oriented demands should be prioritized in the development of pharmaceutical clinics. Moreover， the study also revealed that factors such as gender， age， educational level， and economic burdens exert significant influences on patients’ service demands.

Allergic rhinitis(AR)is the most common airway allergic diseases.Basophils are the classical effector cells in allergy,including AR:Both IgE and non-IgE mediated methods can activate basophils during allergic reactions and induce basophils to release various inflammatory mediators,which is accompanied by changes in the expression of multiple membrane proteins,and ulti-mately leading to the clinical manifestations of allergic diseases.IL-18 may be involved in the pathogenesis of AR by directly inducing basophil activation and inflammation response via binding to its receptor IL-18Rα.Nevertheless,the binding of IL-37b to IL-18Rα initiates the downstream anti-inflammatory signals,thus inhibiting inflammation reaction in AR.Therefore,understanding the role and mechanism of IL-18 and IL-37b in the activation of blood basophils of AR patients is of great significance for the pathogenesis,treat-ment of AR and the development of related biological agents.

Objective To investigate the expression and roles of serine/threonine and tyrosine kinases(TTK)and mouse dual microbody 2(MDM2)in cervical lesion tissue.Methods Patients(n=180)who underwent gynecological surgery at the First Affiliated Hospital of Henan University of Science and Technology from June 2022 to January 2024 were evaluated,including 50 patients in the cervical cancer group,50 patients in the high-grade lesion group,40 patients in the low-grade lesion group,and 40 patients in the non-cervical lesion(control)group.The mRNA expression and protein levels of TTK and MDM2 in each group were detected and compared by real-time quantitative PCR and immunohistochemistry,respectively.The diagnostic value of the mRNA expression levels of TTK and MDM2 in cer-vical cancer was analyzed using receiver operating characteristic curves.Results The mRNA levels of TTK and MDM2 significantly dif-fered among the four groups(P＜0.05);with increases in the lesion grade,the mRNA levels of TTK and MDM2 increased gradually and showed significant differences(P＜0.05).Immunohistochemical results showed that TTK was mainly located in the cytoplasm,whereas MDM2 was mainly located in the nucleus,with positive expression rates in cervical cancer tissues of 84.00％and 90.00％,respectively.These values were higher than those in other pathological tissues(P＜0.05).The mRNA levels of TTK and MDM2 were significantly cor-related with the degree of differentiation and lymph node metastasis(P＜0.05).The receiver operating characteristic curve showed that the areas under the curve of TTK and MDM2 mRNA for diagnosing cervical cancer were 0.803 and 0.798,respectively.Additionally,the area under the curve of the combined diagnosis was 0.912,which was higher than that observed for single detection(Z=2.230,2.553,P＜0.05).Conclusion The mRNA expression of TTK and MDM2 and their corresponding protein levels were increased in cervical lesions,demonstrating their potential as biological indicators for the clinical diagnosis of cervical cancer.
