BACKGROUND: In the interim analysis of MONARCH plus, adding abemaciclib to endocrine therapy (ET) improved progression-free survival (PFS) and objective response rate (ORR) in predominantly Chinese postmenopausal women with HR+/HER2- advanced breast cancer (ABC). This study presents the final pre-planned PFS analysis. METHODS: In the phase III MONARCH plus study, postmenopausal women in China, India, Brazil, and South Africa with HR+/HER2- ABC without prior systemic therapy in an advanced setting (cohort A) or progression on prior ET (cohort B) were randomized (2:1) to abemaciclib (150 mg twice daily [BID]) or placebo plus: anastrozole (1.0 mg/day) or letrozole (2.5 mg/day) (cohort A) or fulvestrant (500 mg on days 1 and 15 of cycle 1 and then on day 1 of each subsequent cycle) (cohort B). The primary endpoint was PFS of cohort A. Secondary endpoints included cohort B PFS (key secondary endpoint), ORR, overall survival (OS), safety, and health-related quality of life (HRQoL). RESULTS: In cohort A (abemaciclib: n  = 207; placebo: n  = 99), abemaciclib plus a non-steroidal aromatase inhibitor improved median PFS vs . placebo (28.27 months vs . 14.73 months, hazard ratio [HR]: 0.476; 95% confidence interval [95% CI]: 0.348-0.649). In cohort B (abemaciclib: n  = 104; placebo: n  = 53), abemaciclib plus fulvestrant improved median PFS vs . placebo (11.41 months vs . 5.59 months, HR: 0.480; 95% CI: 0.322-0.715). Abemaciclib numerically improved ORR. Although immature, a trend toward OS benefit with abemaciclib was observed (cohort A: HR: 0.893, 95% CI: 0.553-1.443; cohort B: HR: 0.512, 95% CI: 0.281-0.931). The most frequent grade ≥3 adverse events in the abemaciclib arms were neutropenia, leukopenia, anemia (both cohorts), and lymphocytopenia (cohort B). Abemaciclib did not cause clinically meaningful changes in patient-reported global health, functioning, or most symptoms vs . placebo. CONCLUSIONS: Abemaciclib plus ET led to improvements in PFS and ORR, a manageable safety profile, and sustained HRQoL, providing clinical benefit without a high toxicity burden or reduced quality of life.

Approximately 60% of colorectal cancer (CRC) patients exhibit TP53 mutations, which are strongly associated with tumor progression, chemotherapy resistance, and an unfavorable prognosis. However, targeting p53 has historically been challenging, and currently, there are no approved p53-based therapeutics for clinical use worldwide. In this study, we discovered that ubiquitin carboxyl terminal hydrolase L3 (UCHL3) plays a crucial role in high-level glycolysis, enhanced stem-like properties, and 5-fluorouracil (5-FU) chemoresistance in TP53-mutant CRC by exerting its deubiquitinating enzyme activity to stabilize α-enolase (ENO1) protein. Notably, we identified a newly Food and Drug Administration (FDA)-approved drug, pacritinib, that potently suppresses UCHL3 expression by blocking the janus kinase 2 (JAK2)-signal transducer and activator of transcription 3 (STAT3) pathway in TP53-mutant CRC. Furthermore, Pacritinib was demonstrated to effectively inhibit glycolysis and improve the sensitivity to 5-FU chemotherapy in TP53-mutant CRC. Our findings suggest that targeting the JAK2-STAT3-UCHL3-ENO1 axis is a promising strategy to suppress glycolysis and enhance the efficacy of 5-FU chemotherapy in TP53-mutant CRC. Pacritinib shows potential for clinical application in the treatment of TP53-mutant CRC.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective: To explore the influencing factors of role adaptation of college freshmen, so as to provide empirical support for developing adaptive education in college. Methods: A cluster sampling method was used to select 3 126 freshmen from six universities of Hefei City and Wuhu City in Anhui Province in October 2022, who were investigated with Positive Psychological Capital Questionnaire (PPQ), Freshmen s Role Adaptability Scale, Connor Davidson Resilience Scale (CD-RISC) and Life Satisfaction Scale. Independent sample t-test and oneway ANOVA were used to compare the scores (caverage score of items) of various variables of college freshmen with different demographic characteristics. Pearson correlation analysis and multiple linear regression analysis were conducted to analyze the correlation. Results: There were statistically significant differences in scores of psychological capital, resilience, life satisfaction and role adaptation among college freshmen of different origin (large and mediumsized cities: ３.６３± ０.５４，３.７３±０.６４，３.４７±０.８０，３.１４±０.６５；county level city or county seat:３.５７±０.５２，３.６１±０.６３，３.３５±０.７５，３.０９±０.６３；villages and towns:３.５０±０.５０，３.５４±０.５８，３.２３±０.７５，３.０６±０.６０), whether in class committee (yes:３.６３±０.５２，３.６９±０.６０，３.４０± ０.７６ ，３.１８±０.５９； no:３.４３±０.５０，３.４８±０.６４，３.２５±０.７７，２.９３±０.６５), father s education level (junior high school or below:３.５２± ０.５１ ，３.５７±０.６１，３.２７±０.７５，３.０７±０.６１； senior high school or technical secondary school:３.６２±０.５３，３.６８±０.６３，３.４４±０.７８，３.１２±０.６３；junior college or above:３.６８±０.５６，３.７８±０.６４，３.５７±０.８０，３.１９±０.６８)，mother s education level(junior high school or below:３.５３±０.５１，３.５８±０.６１，３.２８±０.７５，３.０６±０.６０；senior high school or technical secondary school:３.６３±０.５５，３.７０±０.６３，３.４８±０.７８，３.１５±０.６６；junior college or above:３.７２±０.５４，３.８６±０.６５，３.６２±０.８３，３.２７±０.７０) ( F / t =11.89,21.89,23.02,3.83；10.08，9.20， 5.20 ，10.63；19.34，20.76，29.52，6.44；22.51，26.79，30.94，13.92， P <0.05). The differences of scores in resilience and role adaptation of different genders (boys:3.66±0.64, 3.12±0.65; girls:3.56±0.59, 3.05±0.58) and in life satisfaction whether being an only child (yes:3.40±0.79; no:3.33±0.76) among college freshmen were statistically significant ( t =4.51, 2.75, 2.35, P <0.05). Pearson correlation analysis showed that psychological capital, resilience and life satisfaction of college freshmen were positively correlated with role adaptation ( r =0.49, 0.49, 0.36), while psychological capital, resilience and role adaptation were positively correlated ( r =0.60, 0.59) and Psychological capital was positively correlated with resistance ( r =0.81)( P <0.01). The results of multiple linear regression analysis showed that gender, whether in class committee, psychological capital, resilience and life satisfaction were positively associated with role adaptation among college freshmen ( R 2=0.28, β =0.04, 0.10, 0.23, 0.26, 0.07， P <0.05). Conclusions Role adaptation of college freshmen is related with psychological capital, resilience and life satisfaction. Schools should strengthen mental health education to promote smooth role transition for college freshmen.

The accumulation and spread of prion-like proteins is a key feature of neurodegenerative diseases (NDs) such as Alzheimer's disease, Parkinson's disease, or Amyotrophic Lateral Sclerosis. In a process known as 'seeding', prion-like proteins such as amyloid beta, microtubule-associated protein tau, α-synuclein, silence superoxide dismutase 1, or transactive response DNA-binding protein 43 kDa, propagate their misfolded conformations by transforming their respective soluble monomers into fibrils. Cellular and molecular evidence of prion-like propagation in NDs, the clinical relevance of their 'seeding' capacities, and their levels of contribution towards disease progression have been intensively studied over recent years. This review unpacks the cyclic prion-like propagation in cells including factors of aggregate internalization, endo-lysosomal leaking, aggregate degradation, and secretion. Debates on the importance of the role of prion-like protein aggregates in NDs, whether causal or consequent, are also discussed. Applications lead to a greater understanding of ND pathogenesis and increased potential for therapeutic strategies.

The expert authority coefficients for the two rounds of expert consultation were 0.93 and 0.92, respectively. The Kendall coordination coefficient of various indicators in the second round of expert consultation was 0.227 to 0.288 ( P<0.01). After two rounds of expert consultation, a structured education course for patients with neurogenic bladder during the rehabilitation period was finally developed, including six primary indicators, 21 secondary indicators, and 30 tertiary indicators. Conclusions:The structured education course for patients with neurogenic bladder during the rehabilitation period, based on current situation survey, high-quality evidence, and expert consultation, is comprehensive in content and reasonably designed, which can provide supportive assistance for future nursing health education and management for patients with neurogenic bladder.

Objective:To explore the application of virtual augmented reality (AR) technology combined with transcranial Doppler ultrasound (TCD) in nursing teaching of cerebrovascular diseases.Methods:Eighty-six nursing students who interned in the Department of Neurology of The First Affiliated Hospital of Army Medical University from January 2021 to November 2022 were assigned into control group (students of grade 2021) and research group (students of grade 2022). The control group received traditional teaching with AR technology about the anatomy of the cerebral arterial circle, its composition, and adjacent structures. The research group was given AR-assisted teaching combined with TCD-based demonstration and interpretation. At the end of internship, the assessment scores, satisfaction with teaching, clinical decision-making ability, self-learning ability, and problem-solving ability were compared between the two groups. SPSS 23.0 was used to perform the non-parametric test, t test, and chi-square test. Results:The theoretical, practical, and comprehensive ability assessment scores of the research group [90 (89, 96), 95 (90, 96), and 93 (90, 96), respectively] were significantly higher than those of the control group [89 (87, 91), 90 (89, 92), and 91 (89, 94), respectively]. In terms of satisfaction with teaching effects, teaching methods, teaching content, and teaching style, the scores of the research group [16 (15, 18), (5.98±0.91), (3.38±0.52), and 13 (11, 14), respectively] were significantly higher than those of the control group [14 (13, 16), (4.23±0.65), (2.37±0.36), and 13 (10, 14 ), respectively]. The research group showed significantly better independent learning abilities than the control group in information seeking [(4.66±0.71) vs. (4.00±0.61)] and solution seeking [(4.43±0.68) vs. (4.41±0.67)], with no significant differences in the other dimensions between the two groups. The research group was significantly superior to the control group in all problem-solving dimensions: positive orientation [12 (10, 12) vs. 10 (9, 11)], rationality [26 (23, 28) vs. 21 (21, 24)], negative orientation [15 (13, 20) vs. 20 (17, 20)], avoidance style [17 (15, 18) vs. 19 (17, 20)], and impulsivity/neglect style [16 (15, 18) vs. 18 (16, 20)]. For rounds assessment, the research group showed significantly higher scores than the control group in all the items except " communication with patients" [(9.21±0.39) vs. (9.04±0.53)] and "patient satisfaction with nursing students" [(8.92±0.53) vs. (8.73±0.56)].Conclusions:The teaching method based on AR combined with TCD can improve nursing students' knowledge of cerebrovascular diseases, clinical nursing ability, and satisfaction with teaching.
