OBJECTIVE To prepare an intelligent responsive liposome-hydrogel nanopreparation co-loaded with gambogic acid (GA), and characterize its antitumor activity in vitro . METHODS GA-ICG-Lip-gel was prepared by ethanol injection and cold dissolution, incorporating GA and the photosensitizer indocyanine green (ICG). The appearance and microscopic morphology of GA-ICG-Lip-gel were observed, its encapsulation efficiency and drug loading capacity were measured, and its photothermal conversion performance, photothermal stability, and infrared imaging properties were investigated, along with the determination of its in vitro release profile. Human breast cancer MCF-7 cells were used as objects to investigate the effects of GA-ICG-Lip-gel (or with near-infrared light irradiation) on cell viability, migration ability, and the cellular uptake capacity of GA-ICG-Lip-gel. RESULTS GA-ICG-Lip-gel existed in a solution state at room temperature and transformed into a gel state at 37 ℃. Its microstructure was dense with small pores, and its encapsulation efficiency and drug loading were (96.07±0.86) % and (6.28±1.16) %, respectively. After exposure to near-infrared light, the temperature of GA-ICG-Lip-gel rose above 42 ℃, with no significant attenuation observed in the heating curve. The heating efficiency was dependent on both the irradiation time and drug concentration. Compared to media without gelatinase, the cumulative release rate of GA-ICG-Lip-gel increased in media containing gelatinase. In vitro studies showed that GA-ICG-Lip-gel could be efficiently taken up by MCF-7 cells; GA-ICG-Lip-gel significantly inhibited the viability and migration ability of MCF-7 cells ( P <0.05), and this inhibitory effect was further enhanced under near-infrared light irradiation. CONCLUSIONS This study successfully prepares GA-ICG-Lip-gel, which exhibits favorable photothermal conversion properties and temperature/enzyme dual-responsive drug release characteristics, and demonstrates significant inhibitory effects on the proliferation and migration of breast cancer cells.

Objective To analyze the satisfaction of medical experience of outpatients in multi-campus of a large tertiary public hospital.Methods From January to March 2024,a questionnaire on outpatient satisfaction was sent to the outpatient department of Peking University First Hospital daily based on the Questionnaire Star platform to analyze the outpatient satisfaction rate and satisfaction score of medical services,and the influencing factors of outpatient satisfaction were explored by logistic regression analysis.Results Among the respondents,64.0%expressed high levels of satisfaction while 26.1%reported being relatively satisfied.Waiting time and consultation time play an important role.The diagnosis,treatment and health education and schedule of follow-up visits may affect the outpatient experience.Outpatient payment,outpatient environment,outpatient perceived complaints and timely resolution of dissatisfaction all could affect outpatient satisfaction.Conclusion The overall satisfaction of outpatients was high,and patient satisfaction of outpatient medical services in multi-campuses was consistent.On the premise of ensuring the quality of medical care,hospitals should actively carry out individualized health education,simplify the medical process,extend the outpatient service,and further improved the sense of gain of outpatients.
