High-performance phototheranostics with combined photothermal therapy and photoacoustic imaging have been considered promising approaches for efficient cancer diagnosis and treatment. However, developing phototheranostic materials with efficient photothermal conversion efficiency (PCE), especially over the second near-infrared window (NIR-II, 1000-1700 nm), remains challenging. Herein, we report an ultraefficient NIR-II-activated nanomedicine with phototheranostic and vaccination capability for highly efficient in vivo tumor elimination and metastasis inhibition. The NIR-II nanomedicine of a semiconducting biradical oligomer with a motor-flexible design was demonstrated with a record-breaking PCE of 87% upon NIR-II excitation. This nanomedicine inherently features extraordinary photothermal stability, good biocompatibility, and excellent photoacoustic performance, contributing to high-contrast photoacoustic imaging in living mice and high-performance photothermal elimination of tumors. Moreover, a whole-cell vaccine based on a NIR-II nanomedicine with NIR-II-activated performance was further designed to remotely activate the antitumor immunologic memory and effectively inhibit tumor occurrence and metastasis in vivo, with good biosafety. Thus, this work paves a new avenue for designing NIR-II active semiconducting biradical materials as a promising theranostics platform and further promotes the development of NIR-II nanomedicine for personalized cancer treatment.

Objective:To propose policy recommendations for the compensation mechanism of high-quality development of municipal public hospitals.Methods:Taking the municipal public hospitals in Shanghai as the research object,the aspects of financial subsidies,the structure of medical service income,investment in scientific research and education,and other social compensations were examined to conduct a systematic simulation of the operation of the average municipal public hospital in Shanghai under different policy intervention scenarios.Results:If the current conditions remain unchanged,the average municipal public hospital in Shanghai will face a deficit starting in 2032,the proportion of income from examinations and laboratory tests will surpass that of medical service income in 2026 and 2031,respectively.If the hospitals follow a plan of Combination Plan 3,4,and 5,the average municipal public hospital in Shanghai will be able to break even from 2023 to 2033,and the structure of medical service income will be significantly optimized.Conclusion:To establish a new compensation mechanism for high-quality hospital development that enhances medical services,it is recommended to optimize the structure of government financial compensation,explore rational pricing strategies based on categories,increase investment in scientific research and education while paying attention to the transformation of scientific and technological achievements,expand compensation channels for public hospitals,and improve relevant laws and regulations.

Objective:To evaluate the diagnostic value of coronary angiography-derived fractional flow reserve (FFR) and index of microcirculatory resistance (IMR) for identifying coronary functional abnormalities.Methods:This diagnostic study enrolled patients with clinically suspected or diagnosed coronary artery disease who underwent coronary angiography at Beijing Anzhen Hospital, TEDA International Cardiovascular Hospital, and Qilu Hospital of Shandong University between December 2021 and June 2022. All enrolled patients successfully underwent invasive wire-based FFR and IMR measurements during angiography. In a core laboratory, FFR and IMR for the target vessels were measured using artificial intelligence technology based on coronary angiographic images. Spearman correlation analysis was used to evaluate the correlation between angiography-derived FFR and wire-based FFR, and between angiography-derived IMR and wire-based IMR. Coronary hemodynamic abnormality was defined as FFR≤0.80; the diagnostic performance of angiography-derived FFR for identifying this abnormality was evaluated. Microcirculatory dysfunction was defined as IMR≥25; the diagnostic performance of angiography-derived IMR for identifying microcirculatory dysfunction was evaluated.Results:A total of 181 patients, aged (60.6±8.8) years, with 62 (34.3%) females, and 181 target vessels were included in the final analysis. Angiography-derived FFR showed a significant positive correlation with wire-based FFR ( r=0.78, P<0.001). For identifying coronary hemodynamic abnormality, angiography-derived FFR showed an accuracy of 89.0%, sensitivity of 88.8%, specificity of 89.1%, positive predictive value (PPV) of 88.8%, negative predictive value (NPV) of 89.1%, and an area under the receiver operating characteristic curve ( AUC) of 0.88. Angiography-derived IMR showed a significant positive correlation with wire-based IMR ( r=0.93, P<0.001). For identifying microcirculatory dysfunction, angiography-derived IMR demonstrated an accuracy of 89.5%, sensitivity of 86.8%, specificity of 90.2%, PPV of 70.2%, NPV of 96.3%, and an AUC of 0.95. Conclusion:Angiography-derived FFR and IMR exhibit strong correlations with their invasive wire-based counterparts and demonstrate high diagnostic value for assessing coronary hemodynamics and coronary microcirculatory function.

Objective:To explore the relationship between memory bias, mental imagery, attention bias and depression in college students.Methods:From May to July 2024, a questionnaire was randomly distributed among 72 undergraduate students.The Beck depression inventory and Beck anxiety inventory were used to evaluate the depression and anxiety levels of all participants.The eye tracker was used to record the eye movement data of participants when observing emotional facial images.After the eye movement experiment, the scenario-based event completion task and prospective imagery task were used to collect the memory bias and mental imagery scores of all participants.SPSS 23.0 software was used for Spearman correlation analysis, and PROCESS 3.5 macro program was used for mediating effect test.Results:The scores of college students' negative memory bias, negative mental imagery, negative attention bias and depression were 0.40±0.15, 25.86±9.39, 0.41±0.14, 11.00(5.00, 20.00), respectively.Negative memory bias in college students was significantly and positively correlated with negative mental imagery, negative attention bias and depression ( r=0.832, 0.627, 0.834, all P<0.01).Negative mental imagery in college students was significantly and positively correlated with negative attention bias and depression ( r=0.692, 0.969, both P<0.01).Negative attention bias in college students was significantly and positively correlated with depression ( r=0.693, P<0.01).Negative mental imagery and negative attention bias had significant single chain mediating effect between negative memory bias and depression in college students, accounting for 16.61%(0.146/0.879), 15.70%(0.138/0.879)and 4.89%(0.043/0.879)of the total effect, respectively.

Isolated vertigo due to vascular mechanisms manifests as vertigo, dizziness or imbalance only. Due to the lack of focal neurological symptoms or signs, it is often misdiagnosed as peripheral vestibular disease, resulting in serious adverse consequences. This article reviews the lesion location, cerebrovascular basis, clinical evaluation, and imaging examination of isolated vertigo caused by vascular mechanisms.

The banana Fusarium wilt (BFW) caused by Fusarium oxysporum f. sp. cubense tropical race4 (FocTR4) is difficult to control worldwide, which causes a huge economic losse to banana industry. The purpose of this study was to screen Trichoderma strains with antagonistic activity against FocTR4, to isolate and purify the active compound from the fermentation broth, so as to provide important biocontrol strains and active compound resources. In this work, Trichoderma strains were isolated and screened from the rhizosphere soil of crops, and the strains capable of efficiently inhibiting FocTR4 were screened by plate confrontation, and further confirmed by testing inhibition for the conidial germination and mycelial growth of FocTR4. The phylogenetic tree clarified the taxonomic status of the biocontrol strains. Moreover, the active components in the fermentation broth of the strains were separated and purified by column chromatography, the structure of the most active component was analyzed by nuclear magnetic resonance spectroscopy (NMR), the BFW control effect was tested by pot experiments. We obtained a strain JSHA-CD-1003 with antagonistic activity against FocTR4, and the inhibition rate from plate confrontation was 60.6%. The fermentation broth of JSHA-CD-1003 completely inhibited the germination of FocTR4 conidia within 24 hours. The inhibition rate of FocTR4 hyphae growth was 52.6% within 7 d. A phylogenetic tree was constructed based on the ITS and tef1-α gene tandem sequences, and JSHA-CD-1003 was identified as Trichoderma brevicompactum. Purification and NMR identification showed that the single active compound was trichodermin, and the minimum inhibitory concentration (MIC) was 25 μg/mL. Pot experiments showed that the fermentation broth of strain JSHA-CD-1003 was effective against BFW. The control rate of leaf yellowing was 47.4%, and the rate of bulb browning was 52.0%. Therefore, JSHA-CD-1003 effectively inhibited FocTR4 conidial germination and mycelium growth through producing trichodermin, and showed biocontrol effect on banana wilt caused by FocTR4, thus is a potential biocontrol strain.
