OBJECTIVE To explore comprehensive management and potential issues associated with long-term prescriptions medications of psychiatry， in order to provide a reference for the comprehensive management of long-term prescriptions of psychiatry in psychiatric hospitals and other medical institutions’ pharmacies. METHODS Starting from the applicable principles for long-term prescriptions of psychiatry， this study introduced the standardized assessment and precautions before issuing long-term prescriptions， the formulation and adjustment of the drug list， as well as the rational management of the long-term prescriptions. It also analyzed potential issues that may arise in the comprehensive management of long-term prescription medications and proposed corresponding countermeasures and suggestions. RESULTS & CONCLUSIONS Prior to initiating long-term prescriptions， a standardized assessment should be conducted on patients from the aspects of their psychiatric condition and long-term potential risk factors， pharmacological treatment plans and other non-pharmacological therapies， physical illnesses. Additionally， healthcare providers should fulfill their obligation to inform patients or their family members. The comprehensive management of long-term prescription medications should be jointly established and improved by multiple departments， and the formulation of drug catalogs should avoid including drugs with potential social harm or medication risks while complying with policy requirements. Furthermore， measures such as adding special identifiers to long-term prescriptions， providing patients with reminders about （No.YGLX202537） prescription expiration， or offering online consultations can also effectively enhance the rationality of medication use under long-term prescriptions. Currently， the implementation of long-term prescriptions in psychiatry remains challenged by inconsistencies in prescription duration， incomplete coverage of diagnostic categories， poor patient adherence， and the risk of deviation in clinical assessments. In this regard， measures such as collaborating with multiple departments to strengthen long-term prescription information management， providing matching pharmaceutical services， ensuring the quality and rationality of long-term prescription implementation， and using modern methods to screen high-risk patients can be taken to improve patient medication compliance and safety.

Objective:To investigate the clinical effect of free anterolateral thigh myocutaneous flap combined with oral repair membrane in the reconstruction of nasal mucosa defect after maxillary malignant tumor surgery. Methods:A total of 12 patients with maxillary gingival squamous cell carcinoma and maxillary sinus cancer who had been treated in Department of Oral and Maxillofacial Surgery, Beijing Anzhen Nanchong Hospital, Capital Medical University & Nanchong Central Hospital, were selected from November 2020 to November 2023. Free anterolateral thigh musculocutaneous flap transplantation combined with oral repair membrane were used in all patients. Meanwhile, maxillary soft and hard tissue defects and nasal mucosa defects left after tumor operation were repaired and reconstructed. The clinical effect was evaluated after 6-12 months follow-up. Results:Subtotal maxillary resection was performed in 1 case, total maxillary resection in 9 cases and extended maxillary resection in 2 cases. The musculocutaneous flaps of all patients survived, the facial appearance was basically symmetrical, no obvious depression deformity, the swallowing and speech function recovered well, the mouth and nasal cavity were closed completely, the food could be eaten through the mouth, and the lower nasal passage was not blocked. Conclusion:The free anterolateral thigh musculoflap combined with oral repair membrane can be used to repair and reconstruct maxillary malignant tumor complicated with extensive maxillary tissue and nasal mucosa defect after operation, and the appearance and function can be recovered well after operation, which is a choice for maxillary malignant tumor complicated with nasal mucosa defect.

Traditional development of small protein scaffolds has relied on display technologies and mutation-based engineering, which limit sequence and functional diversity, thereby constraining their therapeutic and application potential. Protein design tools have significantly advanced the creation of novel protein sequences, structures, and functions. However, further improvements in design strategies are still needed to more efficiently optimize the functional performance of protein-based drugs and enhance their druggability. Here, we extended an evolution-based design protocol to create a novel minibinder, BindHer, against the human epidermal growth factor receptor 2 (HER2). It not only exhibits super stability and binding selectivity but also demonstrates remarkable properties in tissue specificity. Radiolabeling experiments with ^99mTc, ⁶⁸Ga, and ¹⁸F revealed that BindHer efficiently targets tumors in HER2-positive breast cancer mouse models, with minimal nonspecific liver absorption, outperforming scaffolds designed through traditional engineering. These findings highlight a new rational approach to automated protein design, offering significant potential for large-scale applications in therapeutic mini-protein development.

Objective:To explore the cost control effect and cost-shifting effect of Diagnosis-Intervention Packet(DIP)payment reform on inpatient coronary heart disease patients.Methods:Z City,a national pilot city for DIP,is taken as a case study.It utilizes inpatient claims data and the propensity scoring matching-difference in differences method to evaluate the impact of DIP payment reform on total medical expenses,Out-of-Pocket(OOP),the OOP proportion,self-paid Category B expenses,the proportion of self-paid Category B expenses,Category C expenses,and the proportion of Category C expenses for coronary heart disease inpatients.Results:After the DIP reform,the total medical expenses per inpatient coronary heart disease patient significantly decreased(β=-0.127,P＜0.01).Regarding cost-shifting,the OOP expenses(β=0.108,P＜0.05),the OOP proportion(β=0.055,P＜0.01),self-paid Category B expenses(β=0.239,P＜0.01),the proportion of self-paid Category B expenses(β=0.030,P＜0.01),and the proportion of Category C expenses significantly increased(β=0.026,P＜0.01),while there was no significant change in Category C expenses.Conclusion:The DIP reform significantly reduced the total medical expenses per inpatient case of coronary heart disease.At the same time,the reform shifted costs from within the scope of the insurance policy to outside the policy's coverage,with a stronger shift observed from Category B to Category C expenses.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
