Patients with rare disease are a vulnerable group in healthcare who urgently need more attention from the government and society. Despite their overall number, they face challenges such as limited diagnosis and treatment options, poor access to medications, and heavy financial burdens. Providing better protection for this group is not only essential for public well-being, but also an important indicator of societal progress. This paper analyzes the current status and challenges of rare disease protection in China, with a focus on building diagnostic and treatment networks, optimizing the multitiered social security system, and improving pharmaceutical access mechanisms. It highlights issues such as incomplete health insurance coverage, unequal resource allocation, and insufficient incentives for drug development. To address these challenges, we suggest strengthening policies, improving the multitiered social security system, encouraging social support, and promoting medical and pharmaceutical innovation to provide comprehensive care for rare disease patients.

With the development of the economy and technological progress,more and more animal-derived mesh products are being utilized in the medical field for tissue and organ repair and replacement.Owing to the complexity of their structure and production process,these animal-derived meshes still face several challenges in practical applications,such as insufficient mechanical strength,rapid degradation rates,and the detection of harmful leachable substances.Among these challenges,the production process is a key factor affecting product quality.This paper reviews the key aspects of the production process and quality control for animal-derived meshes in China,offering new insights for the quality control and regulatory oversight of such products.

Objective To construct the etoposide (VP-16)combined with cisplatin (DDP) chemotherapy scheme (EP chemotherapy scheme)resistant small cell lung cancer (SCLC)cell line H446/EP and to identify the drug resistance characteristics and explore the mechanism.Methods NCI-H446 cells were treated with increasing concentrations of VP-16 and DDP to construct an H446/EP cell line.H446/EP and NCI-H446 cells were used as the research objects.The cell viability was detected by MTT assay,and the resistance index (RI)of H446/EP cells was calculated.Cell cloning assay and Incucyte cell proliferation (label-free)assay were used to detect cell proliferation ability.Transcriptome sequencing was performed to analyze the enrichment of differentially expressed genes (DEGs)in the 2 cell lines.Western blotting was applied to detect the protein expression levels of drug resistance,DNA damage repair (DDR),and autophagy markers.Results MTT assay showed that the resistance index (RI)of H446/EP cells to VP-16,DDP,and DOX were 6.14,3.43,and 1.96,respectively.The results of cell cloning assay and Incucyte cell proliferation assay indicated that the proliferation ability was significantly higher in the H446/EP cells than the NCI-H446 cells (P<0.01).Transcriptome sequencing and pathway enrichment analysis displayed that the DEGs between H446/EP and NCI-H446 cells were enriched in tumor chemoresistance,DDR,and autophagy pathways.Western blot results showed the expression levels of MRP1,BCRP,RAD51,γ-H2AX,and LC3-Ⅱ/LC3-Ⅰ were significantly increased,and that of p62 was obviously decreased in the H446/EP cells when compared with the NCI-H446 cells (P<0.05).Conclusion An EP chemotherapy-resistant H446/EP cell line is successfully constructed.Stronger proliferation ability,increased expression of efflux transporters,and enhanced DDR and autophagy may be the mechanisms of the resistance of SCLC to EP chemotherapy scheme.

The medical assistance system plays a backup role in China's multi-level medical security system,and has achieved important phased results in improving the accessibility and affordability of medical services for disadvantaged groups.However,there is still insufficient protection for medical assistance in China,and the phenomenon of"poverty caused by illness and returning to poverty due to illness"still exists.Therefore,it summarizes and analyzes the current development status of China's medical assistance system by reviewing national policy documents and analyzing local situations,summarizes and analyzes the existing problems,and proposes countermeasures and suggestions.

The reform of medical insurance payment is a critical part of deepening the medical reform.It plays an important role in guiding the behavior of healthcare providers.The latest progress in the reform of health insurance payment in the US.is the imple-mentation of value-based payment models.The literature research method is applied to review the development of value-based pay-ment practices in the US.It finds the main value-based payment models in the United States are targeted hospitals and physicians as the incentive object,with the characteristics of the combination of reward and punishment,the combination of horizontal and ver-tical evaluation,the continuous improvement of evaluation system,and the full use of information means.On this basis,combined with the national conditions of China,it puts forward four suggestions on establishing effective incentive mechanism,formulating scientific evaluation system,insisting on continuous improvement mechanism and strengthening medical information construction for future reform of medical insurance.

Objective It aims to investigate the current status of patient trust in physicians among inpatients at tertiary public hospitals in China and to analyze the factors influencing this trust.The goal is to provide insights for enhancing patient trust and improving doctor-patient relationships.Methods Relying on the third"third party evaluation of national action to improve medical services"project,it surveyed inpatients from 136 tertiary public hospitals across 31 provinces(including autonomous regions and municipalities)and the Xinjiang Production and Construction Corps.A total of 21 092 inpatient questionnaires were returned.Data obtained were statistically analyzed using R software version 4.3.2.Results The trust level in attending physicians among inpatients at tertiary public hospitals in China was found to be 98.37％.Influential factors on this trust level included patient occupation,annual family income,type and region of the hospital and so on.Conclusion Overall,the level of trust in physicians among inpatients at tertiary public hospitals in China is high,though regional differences exist.It should pay attention to non-medical factors such as inpatient ward environment and hospital service quality.Improving these aspects can enhance the overall patient experience,further improve doctor-patient relationships.

Objective It aims to investigate the status quo of nurses'emotional exhaustion in tertiary public hospitals in China and analyze its influencing factors,so as to provide suggestions for formulating targeted policy measures to reduce nurses'emotional exhaustion.Methods Relying on the fifth"The Third-Party Evaluation of the China Healthcare Improvement Initiatives"project,it surveyed nurses from 143 tertiary public hospitals across 31 provinces(including autonomous regions and municipalities)and the Xinjiang Production and Construction Corps.Univariate analyses were performed using the Pearson chi-square test.Multifactorial analyses were performed using ordered multicategorical logistic regression analysis.Results The score of nurses'emotional exhaustion in tertiary public hospitals in China was 8.00(2.00～16.00),of which mild exhaustion accounted for 79.00％,moderate exhaustion accounted for 10.00％,and severe exhaustion accounted for 11.00％.Gender,age,number of children,region,type of hospital,department,employment form,assume scientific research task,excessive workload,salary and hospitals carry out psychological guidance were the influencing factors of nurses'emotional exhaustion.Conclusion Nurses in tertiary public hospitals in China are at a mild level of emotional exhaustion,but in some groups the degree is more serious.Policy makers and hospital managers should focus on special groups,implement the reform of salary system,reduce nurses'workload,reasonably arrange working hours,improve the working environment of hospitals,and strengthen nurses'psychological guidance.
