OBJECTIVES: Stigma is common among community-dwelling patients with schizophrenia and has a profound negative impact on both psychiatric symptoms and quality of life. This study aims to explore the association between stigma and quality of life in this population and to examine the multiple mediating roles of anxiety and depression symptoms. METHODS: The multi-stage stratified cluster random sampling method was used to select the community-dwelling patients with schizophrenics in Chengdu, Sichuan Province, China. The questionnaire included general demographic characteristics, stigma question, the Generalized Anxiety Disorder-7 (GAD-7) scale, the Patient Health Questionnaire-9 (PHQ-9), and the 12-item Short Form Health Survey (SF-12). The SF-12 was used to measure quality of life, including physical health and mental health dimensions. A multiple mediation model was used to analyse the mediating effects of anxiety and depression symptoms together between stigma and quality of life. RESULTS: A total of 1 087 community patients with schizophrenia were included with a mean age of 50.68±12.73 years; 525 (48.30%) were male. Stigma was reported by 543 patients (49.95%). Anxiety symptoms were present in 292 patients (26.86%), and depression symptoms in 407 patients (37.44%). The physical health quality of life score was 72.01 ± 20.99, and the mental health quality of life score was 71.68 ± 19.38. Multiple mediation analysis showed that stigma directly affected quality of life, and also indirectly affected quality of life through anxiety and depression symptoms. Anxiety and depression jointly mediated 42.26% of the total effect of stigma on physical health quality of life and 47.51% on mental health quality of life. CONCLUSIONS Reducing stigma and preventing anxiety and depression symptoms in community-dwelling patients with schizophrenia can effectively improve their quality of life and support reintegration into society.

Loss-of-function variants of low-density lipoprotein receptor-related protein 5 (LRP5) can lead to reduced bone formation, culminating in diminished bone mass. Our previous study reported transcription factor osterix (SP7)‍-binding sites on the LRP5 promoter and its pivotal role in upregulating LRP5 expression during implant osseointegration. However, the potential role of SP7 in ameliorating LRP5-dependent osteoporosis remained unknown. In this study, we used mice with a conditional knockout (cKO) of LRP5 in mature osteoblasts, which presented decreased osteogenesis. The in vitro experimental results showed that SP7 could promote LRP5 expression, thereby upregulating the osteogenic markers such as alkaline phosphatase (ALP), Runt-related transcription factor 2 (Runx2), and β‍-catenin (P<0.05). For the in vivo experiment, the SP7 overexpression virus was injected into a bone defect model of LRP5 cKO mice, resulting in increased bone mineral density (BMD) (P<0.001) and volumetric density (bone volume (BV)/total volume (TV)) (P<0.001), and decreased trabecular separation (Tb.‍Sp) (P<0.05). These data suggested that SP7 could ameliorate bone defect healing in LRP5 cKO mice. Our study provides new insights into potential therapeutic opportunities for ameliorating LRP5-dependent osteoporosis.

Traditional development of small protein scaffolds has relied on display technologies and mutation-based engineering, which limit sequence and functional diversity, thereby constraining their therapeutic and application potential. Protein design tools have significantly advanced the creation of novel protein sequences, structures, and functions. However, further improvements in design strategies are still needed to more efficiently optimize the functional performance of protein-based drugs and enhance their druggability. Here, we extended an evolution-based design protocol to create a novel minibinder, BindHer, against the human epidermal growth factor receptor 2 (HER2). It not only exhibits super stability and binding selectivity but also demonstrates remarkable properties in tissue specificity. Radiolabeling experiments with ^99mTc, ⁶⁸Ga, and ¹⁸F revealed that BindHer efficiently targets tumors in HER2-positive breast cancer mouse models, with minimal nonspecific liver absorption, outperforming scaffolds designed through traditional engineering. These findings highlight a new rational approach to automated protein design, offering significant potential for large-scale applications in therapeutic mini-protein development.

Apical microsurgery is accurate and minimally invasive, produces few complications, and has a success rate of more than 90%. However, due to the lack of awareness and understanding of apical microsurgery by dental general practitioners and even endodontists, many clinical problems remain to be overcome. The consensus has gathered well-known domestic experts to hold a series of special discussions and reached the consensus. This document specifies the indications, contraindications, preoperative preparations, operational procedures, complication prevention measures, and efficacy evaluation of apical microsurgery and is applicable to dentists who perform apical microsurgery after systematic training.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

OBJECTIVE: To investigate the therapeutic effects of Banxia Xiexin Decoction (BXD), a herbal medicine formula, on inflammation and the imbalance of the gut microbiota in a rat model of colorectal cancer (CRC) induced by azoxymethane (AOM) /dextran sulfate sodium (DSS). METHODS: A total of 75 male C57BL/6 mice were randomly divided into five groups: normal control group (NC), model group (MODEL), low-dose BXD treatment group (L-BXD), high-dose BXD treatment (H-BXD) group and MS treatment group (MS). BXD and MS were used in CRC mice at the doses of 3.915 g/kg, 15.66 g/kg, 0.6 g/kg for 3 weeks consecutively. Histopathological changes in the colon were observed using hematoxylin-eosin (HE) staining. The content of inflammatory factors in serum was detected by an enzyme-linked immunosorbent assay (ELISA), and the expression of mRNA and protein of genes related to immunity, apoptosis, inflammation, and inflammatory factors was evaluated. Changes in the intestinal flora of mouse fecal were determined based on high-throughput sequencing of the 16S rRNA microbial gene. RESULTS: Compared to the model group, the low-dose BXD and high-dose BXD groups decreased the number of colon tumors, reversed weight loss, and shortened colon length of mice. The pathological examination showed that BXD alleviated the malignancy of intestinal tumors. It also suppressed signal transducer and activator of transcription 3 (STAT3), matrix metalloproteinase-9 (MMP-9), and transforming growth factor beta 1 (TGF-β1) expression, while increasing the expression of the tight junction protein ZO-1 in colon tissues. Additionally, the levels of key pathway proteins involved in inflammation (phosphorylated-STAT3, Bcl-2, COX-2) and cell cycle regulatory molecules (c-Myc and PCNA) were reduced. According to 16S rRNA sequence analysis, BXD enhanced the relative abundance of potentially beneficial bacteria, while that of cancer-related bacteria decreased. CONCLUSION BXD plays a preventive role in developing colorectal cancer; its mechanisms are related to the inhibition of inflammation and tumor proliferation, as well as maintenance of intestinal homeostasis.

Objective:To investigate the efficacy of venetoclax combined with hypomethylating agents (Ven-HMA), in patients with core binding factor acute myeloid leukemia (CBF-AML) intolerant to intensive induction therapy.Methods:This study retrospectively analyzed patients newly diagnosed with CBF-AML who were aged <60 years and who received Ven-HMA as induction therapy at the Department of Hematology, the First Affiliated Hospital of Soochow University, between January 2020 and June 2023. Baseline characteristics and treatment responses of the patients were collected.Results:A total of 70 treatment-na?ve patients receiving Ven-HMA induction therapy were enrolled, of which 38 were men and 32 women [median age: 43 (34 - 55) years]. Of the 70 patients, 44 (62.9%) achieved complete remission (CR) /CR with incomplete hematologic recovery (CRi), 16 (22.9%) achieved partial remission, and 10 (14.2%) exhibited no response after one induction cycle. Among the 32 t (8;21) -positive patients with AML, only 8 (25.0%) achieved CR/CRi, of whom 3 (37.5%) remained measurable residual disease (MRD) -positive; among the 38 inv (16) -positive patients, 36 (94.7%) achieved CR/Cri, of whom 12 (33.3%) remained MRD-positive. Patients harboring the CBFβ::MYH11 fusion gene showed significantly higher response rates to Ven-HMA induction than those with the RUNX1:: RUNX1T1 fusion gene ( P<0.01) . Conclusion:Ven-HMA represents a novel therapeutic strategy that exhibits significant efficacy in inv (16) -positive patients; however, it demonstrates relatively lower remission rates in t (8; 21) -positive patients.

[Summary]Diabetic peripheral neuropathy(DPN)is one of the most common complications of diabetes.The blood nerve barrier(BNB)is a barrier structure located in peripheral nerve tissue,protecting nerve tissue from toxic substances in the blood and maintaining material exchange and information transmission between nerves and blood.Studies have shown that changes in BNB may be the initial event leading to the occurrence of DPN.After BNB is destroyed,blood-borne pathogens can directly damage peripheral nerves and cause DPN.This article will review the physiological and pathological characteristics of BNB,the relationship between BNB and DPN,and the research progress in targeting BNB for the treatment of DPN.
