BACKGROUND: T cell dysfunction, which includes exhaustion, anergy, and senescence, is a distinct T cell differentiation state that occurs after antigen exposure. Although T cell dysfunction has been a cornerstone of cancer immunotherapy, its potential in transplant research, while not yet as extensively explored, is attracting growing interest. Interferon regulatory factor 4 (IRF4) has been shown to play a pivotal role in inducing T cell dysfunction. METHODS: A novel ultra-low-dose combination of Trametinib and Rapamycin, targeting IRF4 inhibition, was employed to investigate T cell proliferation, apoptosis, cytokine secretion, expression of T-cell dysfunction-associated molecules, effects of mitogen-activated protein kinase (MAPK) and mammalian target of rapamycin (mTOR) signaling pathways, and allograft survival in both in vitro and BALB/c to C57BL/6 mouse cardiac transplantation models. RESULTS: In vitro , blockade of IRF4 in T cells effectively inhibited T cell proliferation, increased apoptosis, and significantly upregulated the expression of programmed cell death protein 1 (PD-1), Helios, CD160, and cytotoxic T lymphocyte-associated antigen (CTLA-4), markers of T cell dysfunction. Furthermore, it suppressed the secretion of pro-inflammatory cytokines interferon (IFN)-γ and interleukin (IL)-17. Combining ultra-low-dose Trametinib (0.1 mg·kg -1 ·day -1 ) and Rapamycin (0.1 mg·kg -1 ·day -1 ) demonstrably extended graft survival, with 4 out of 5 mice exceeding 100 days post-transplantation. Moreover, analysis of grafts at day 7 confirmed sustained IFN regulatory factor 4 (IRF4) inhibition, enhanced PD-1 expression, and suppressed IFN-γ secretion, reinforcing the in vivo efficacy of this IRF4-targeting approach. The combination of Trametinib and Rapamycin synergistically inhibited the MAPK and mTOR signaling network, leading to a more pronounced suppression of IRF4 expression. CONCLUSIONS Targeting IRF4, a key regulator of T cell dysfunction, presents a promising avenue for inducing transplant immune tolerance. In this study, we demonstrate that a novel ultra-low-dose combination of Trametinib and Rapamycin synergistically suppresses the MAPK and mTOR signaling network, leading to profound IRF4 inhibition, promoting allograft acceptance, and offering a potential new therapeutic strategy for improved transplant outcomes. However, further research is necessary to elucidate the underlying pharmacological mechanisms and facilitate translation to clinical practice.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

[Purpose]To analyze the incidence and mortality of female breast cancer in Zhejiang cancer registration areas in 2021 and the trends from 2000 to 2021.[Methods]The data of cancer inci-dence,mortality and population data reported by cancer registration areas in Zhejiang Province from 2000 to 2021 were collected.The crude incidence/mortality rates,age-standardized rates ad-justed by Chinese standard population(ASIRC,ASMRC)and world standard population(ASIRW,ASMRW),cumulative rates(0～74 years old),truncated rates(35～64 years old),proportion of fe-male breast cancer and age-specific rate were calculated.The average annual percentage change(AAPC)of female breast cancer incidence and mortality rates in Zhejiang from 2000 to 2021 was calculated using Joinpoint software.[Results]In 2021,there were 7 262 new cases of female breast cancer in Zhejiang cancer registration areas,accounting for 12.70％of all new female can-cer cases.The crude incidence rate,ASIRC and ASIRW were 65.71/105,42.03/105 and 39.22/105,respectively.The cumulative incidence rate(0～74 years old)was 4.26％,and the truncated rate(35～64 years old)was 98.34/105.The ASIRC in urban and rural areas were 43.15/105 and 40.15/105,respectively.There were 992 deaths of female breast cancer,accounting for 6.97％of all female cancer deaths.The crude mortality rate,ASMRC and ASMRW were 8.98/105,4.62/105 and 4.47/105,respectively.The cumulative mortality rate(0～74 years old)was 0.48％,and the truncated rate(35～64 years old)was 8.89/105.The ASMRC in urban and rural areas were 4.79/105 and 4.34/105,respectively.The incidence rate of female breast cancer reached the peak at the age group of 60～64 years old,and the mortality rate reached the peak at the age group of 85 years old and above.From 2000 to 2021,the crude incidence rate,ASIRC and ASIRW of female breast cancer in Zhejiang cancer registration areas showed significant increasing trends(all P＜0.05).The crude mortality rate and ASMRW of female breast cancer also showed significant increasing trends(all P＜0.05).[Conclusion]The incidence rate of female breast cancer in Zhejiang Province was higher than the national average,while the mortality rate was lower than the national average in 2021.Both the incidence and mortality rates showed increasing trends from 2000 to 2021.Fur-thermore,distinct urban-rural disparities existed in both incidence and mortality characteristics.

Objective To observe the value of transabdominal bowel ultrasound for monitoring therapeutic efficacy of vedolizumab in patients with moderate-to-severe ulcerative colitis.Methods Totally 47 ulcerative colitis patients with Mayo endoscopic score(MES)≥2 and treated with vedolizumab were retrospectively included.Transabdominal bowel ultrasound examinations were performed at baseline,at the end of induction therapy,also 3 and 6 months after maintenance therapy,while colonoscopy was performed at baseline and 6 months after maintenance therapy.According to colonoscopy results 6 months after maintenance therapy,the patients were divided into improved group(MES≤1 or MES reduction≥1,n=25)and non-improved group(n=22),and ultrasonic findings of sigmoid colon were compared between and within groups.Results At baseline,no significant difference of ultrasonic findings of sigmoid colon was observed between groups(all P＞0.05),whereas differences of bowel wall thickness at the end of induction therapy,of Limberg grade and abnormal perienteric lymph nodes 3 months after maintenance therapy,as well as bowel wall stratification 6 months after maintenance therapy were noticed between groups(all P＜0.05).Within improved group,compared with those in baseline,bowel wall thickness improved at all time points after the beginning of treatment,Limberg grade improved 3 and 6 months after maintenance therapy,while bowel wall stratification,abnormal perienteric lymph node and perienteric fat edema improved 6 months after maintenance therapy(all P＜0.05).Meanwhile,no significant change of ultrasonic findings of sigmoid colon was observed in non-improved group during the above periods(all P＞0.05).Conclusion Transabdominal bowel ultrasound could be used to accurately monitor the therapeutic efficacy of vedolizumab in patients with moderate-to-severe ulcerative colitis.

This research aimed to comprehensively understand the prevalence of mutation in drug-resistant molecular markers of imported Plasmodium vivax in Chongqing,the Pvmdr1,Pvdhps,Pvdhfr,Pvcrt-o and Pvk12 genes of Plasmodium vivax were systematically analyzed.Blood samples were collected from imported Plasmodium vivax-infected patients in Chongqing between 2011 and 2022.The Pvmdr1,Pvdhps,Pvdhfr,Pvcrt-o,and Pvk12 genes were amplified and then sequenced to precisely evaluate gene mutations.Bioinformatics methods were employed to conduct in depth analysis of the mutation prevalence.Regarding the Pvdhfr gene,mutations at codons 50,57,58,61,99,117,and 199 were detected in 2.9%,23.5%,76.4%,23.53%,2.9%,82.3%,and 5.88%of the samples,respectively.The double-mutant haplotype S58R/S117N was the most prevalent,accounting for 50%,followed by the quadruple-mutant haplotype F57L/S58R/T61M/S117T,which accounted for 11.76%.Among the four types of tandem-repeat variations of Pvdhfr,the wild-type was the most common,and the insertion type was a novel discovery in this study.For the Pvdhps gene,the prevalence among mutation genotypes was relatively low.The single-mutant genotype was dominant,constituting 27.03%.The prevalence of Pvmdr1 mutations at codons 958 and 1076 was 100%and 89.19%,respectively.Among the 37 successfully sequenced samples,K10 insertion was detected in only 8 cases(22.22%).Notably,no non-synonymous mutations of Pvk12 were identified in this study.The cases in this study were imported from various countries of origin.Novel tandem-repeat variation tyres of Pvdhfr and new mutation sites of Pvdhps were identifide,thus enriching the mutation information of imported Plasmodium vivax resistance molecular markers in China.

Objective:To identify key influencing factors and their structural relationships for continuity of care and care coordination in integrated healthcare systems,providing evidence for systemic improvement strategies.Methods:Taking the Yuhuan Health Consortium in Zhejiang Province as an example,this study integrated the Decision-Making Trial and Evaluation Laboratory(DEMATEL)and Adversarial Interpretive Structure Modeling(AISM).An expert questionnaire and literature review were used to construct a factor system,quantifying the influence degree,centrality,and hierarchical structure of 17 continuity and 14 coordination factors.Results:In the system of continuity of care,division-of-labor and linkage mechanisms(influence degree:2.516)and payment methods(causal degree:1.043)were identified as core drivers,forming a four-level interaction network.For care coordination,health planning(centrality:4.452)and health insurance policies(causal degree:1.131)emerged as root causes,establishing a three-tier hierarchical structure.Topological analysis revealed that continuity relies on the"institutional design-process articulation-patient perception"pathway,while coordination depends on the"policy traction-management synergy-technical support"linkage mechanism.Both systems shared disease characteristics(causal degree:1.650/1.384)as underlying drivers,yet service processes(centrality:4.680)and managerial awareness(centrality:4.754)served as unique hub nodes.Conclusion:Differentiated interventions are required:continuity improvement should prioritize payment reform and division-of-labor mechanisms,while coordination enhancement necessitates strengthened health planning and policy synergy.
