Objective:It aims to investigate the impact of enhancing the outpatient total cost for urban and rural residents on total outpatient costs and medication expenses,providing policy recommendations for improving outpatient coverage under city-level coordination.Methods:Using Pilot County as a case study and outpatient medical record data,the PSM-DID method is employed to evaluate the effect of raising the Outpatient Medical Insurance level on total outpatient costs and medication expenses per case.Results:After improving the Outpatient Medical Insurance level,total outpatient costs per case increased significantly by 3.87%(P＜0.05),while medication expenses per case decreased significantly by 10.90%(P＜0.001).For the elderly,total outpatient costs per case rose significantly by 6.08%(P＜0.05),while there is a increase for non-elderly patients(P＞0.05).Medication expenses per case for the elderly decreased significantly by 11.32%(P＜0.001),while non-elderly patients saw a 7.85%decrease(P＞0.05).Conclusion:The improvement in the outpatient coordinated hierarchy significantly increased the total cost for urban and rural residents while significantly reducing medication expenses.The impact on outpatient costs was more pronounced among the elderly.It is recommended that policy design for enhancing the general outpatient coordination level for urban and rural residents consider both equity and efficiency.

BACKGROUND:Chronic rotator cuff injury is often companied by tendon degeneration and impaired function of tendon-derived stem cells.As am important cytokine,platelet-derived growth factor-DD has a regulatory effect on the proliferation and differentiation of tendon-derived stem cells.OBJECTIVE:To investigate the effect of platelet-derived growth factor-DD on the proliferation and multilineage differentiation of tendon-derived stem cells in human chronic rotator cuff injury.METHODS:Tendon-derived stem cells were isolated from human chronic rotator cuff injury tissue and cultured in vitro.Immunofluorescence staining was used to observe the cytoskeletal morphology of tendon-derived stem cells.Flow cytometry was used to identify the phenotype of tendon-derived stem cells.Tendon-derived stem cells were divided into two groups.The control group did not receive any intervention.The platelet-derived growth factor-DD group was treated with 5 μg/mL platelet-derived growth factor-DD.The effect of platelet-derived growth factor-DD on the proliferation and multilineage differentiation of tendon-derived stem cells was evaluated by cell proliferation assay and three-lineage differentiation assay.RESULTS AND CONCLUSION:(1)The number of EdU-positive cells in the platelet-derived growth factor-DD group was significantly increased compared with the control group(P＜0.05).Tendon-derived stem cells entered the rapid proliferation phase earlier,and the cell growth was logarithmic.(2)The positive areas of Oil Red O staining,Alcian Blue staining,and Alizarin Red staining in the platelet-derived growth factor-DD group were significantly larger than those in the control group(P＜0.05).(3)The above results show that platelet-derived growth factor-DD significantly promotes the proliferation and adipogenic,osteogenic,and chondrogenic differentiation of tendon-derived stem cells.

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.

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.
