Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

The core components of the Hippo signaling pathway encompass upstream regulatory molecules,core kinase cascade complexes,and downstream transcriptional regulation complexes.This pathway modulates cellular behaviors by influencing the effector molecules of its core components and plays a pivotal role in immune regulation.Effector molecules,such as Yes-associated protein(YAP),transcriptional coactivator with PDZ-binding motif(TAZ),transcriptional enhanced associate domain transcriptional factor(TEAD),monopolar spindle-one binder(MOB1),large tumor suppressor(LATS),can stimulate fibroblast-like synovial cell migration and invasion in rheumatoid arthritis,regulate osteoarthritis disease progression,promote pathological new bone formation in ankylosing spondylitis,sustain submandibular gland development while delaying Sjogren's syndrome progression,mediate alpha-smooth muscle actin in systemic sclerosis,and refine the regulation of target genes associated with pulmonary fibrosis.This article provides an overview of the regulatory mechanisms involving Hippo signaling pathway-related effector molecules in the pathogenesis and progression of rheumatic immune system diseases,to serve as a reference for exploring novel therapeutic targets of rheumatic immune system diseases.

Objective To investigate the effect of osteoblast-derived exosome(Exo)mediating microRNA(miR)-494 on bone metabolism and bone remodeling balance in osteoporosis(OP)rats and its mechanism.Methods Exosomes was isolated and identified from MC3T3-E1 osteoblast cell line and transferred to Exo by electrical transfer.Forty SD rats were randomly divided into control,model,miR-494 mimic(miR-494),and miR-494 inhibitor group,10 rats in each group.The ovaries were removed to construct the OP model except the control group.After modeling,the miR-494 group and miR-494 inhibitor group received tail vein injections of exosomes containing the corresponding miRNA,at a dose of 3×109 particles.Four weeks later,bone parameters were detected in each group of rats by Micro-CT,serum bone markers were measured by ELISA,pathological changes in bone tissue were observed by HE staining,osteoclast numbers were detected by tartrate-resistant acid phosphatase(TRACP)staining,and the expression levels of bone remodeling-related proteins and toll-like receptor 4(TLR4)pathway-related proteins were determined by Western blotting.Results Typical cup-shaped or round exosomes were successfully isolated with a diameter of about 100 nm from MC3T3-E1 cells,which contained CD63,CD9,tumor susceptibility gene 101(TSG101),heat shock protein 70(HSP70)proteins and can be taken up by MC3T3-E1 cells.Compared with the model group,the bone parameters of the rats in the miR-494 mimic group decreased,serum bone markers bone Gla protein(BGP),TRACP,C-terminal telopeptide of type Ⅰ collagen(CTX-Ⅰ)increased,osteoprotegerin(OPG),procollagen type Ⅰ N-terminal propeptide(PⅠNP)decreased,bone trabeculae structure was disordered,osteoclasts increased,bone morphogenetic protein 2(BMP-2),Runt related transcription factor 2(RUNX2)in bone tissue downregulated,receptor activator of nuclear factor kappa-B ligand(RANKL)upregulated,TLR4,nuclear factor kappa-B p65(NF-κB p65)and myeloid differentiation primary response 88(MyD88)upregulated(all P＜0.05).In contrast,the situation of the miR-494 inhibitor group was opposite,bone parameters and OPG,PⅠNP increased,BGP,TRACP,CTX-Ⅰdecreased,bone structure returned to normal,osteoclasts decreased,BMP-2,RUNX2 in bone tissue upregulated,RANKL downregulated,TLR4,NF-κB p65 and MyD88 downregulated(all P＜0.05).Conclusion The transfer of miRNA-494 by Exo aggravates abnormal bone metabolism in OP rats and inhibits bone remodeling balance,suggesting that the mechanism of action may be related to the regulation of TLR4 pathway.

OBJECTIVE: To observe the clinical significance of translocator proteins (TSPO) gene in the treatment of FLT3-ITD/DNMT3A R882 double-mutated acute myeloid leukemia (AML). METHODS: Seventy-six patients with AML hospitalized in the Department of Hematology of the Affiliated People's Hospital of Ningbo University from June 2018 to June 2020 were selected, including 34 patients with FLT3-ITD mutation, 27 patients with DNMT3A R882 mutation, 15 patients with FLT3-ITD/DNMT3A R882 double mutation, as well as 19 patients with immune thrombocytopenia (ITP) hospitalized during the same period as control group. RNA was routinely extracted from 3 ml bone marrow retained during bone puncture, and TSPO gene expression was detected by transcriptome sequencing (using 2-deltadeltaCt calculation). RESULTS: The expression of TSPO gene in FLT3-ITD group and DNMT3A R882 group at first diagnosis was 2.02±1.04 and 1.85±0.76, respectively, which were both higher than 1.00±0.06 in control group, but the differences were not statistically significant (P=0.671, P=0.821). The expression of TSPO gene in the FLT3-ITD/DNMT3A R882 group was 3.98±1.07, wich was significantly higher than that in the FLT3-ITD group and DNMT3A R882 group, the differences were statistically significant (P=0.032, P=0.021). The expression of TSPO gene in patients who achieved complete response after chemotherapy in the FLT3-ITD/DNMT3A R882 group was 1.19±0.87, which was significantly lower than that at first diagnosis, and the difference was statistically significant (P=0.011). CONCLUSION TSPO gene may be used as an indicator of efficacy in FLT3-ITD /DNMT3A R882 double-mutated AML.

Objective:To explore the development trends, frontiers, and hotspots of research on early rehabilitation for patients with severe neurological diseases at home and abroad in the past 10 years, with a view to providing reference for the development of early rehabilitation for patients with severe neurological diseases in China.Methods:The article on early rehabilitation for patients with severe neurological diseases was systematically searched in the Web of Science and China National Knowledge Infrastructure (CNKI) . The search period was from January 1, 2012 to June 1, 2022. CiteSpace software was used to construct a visual graph of early rehabilitation for patients with severe neurological diseases in authoritative databases in both Chinese and English, for agency cooperation, author cooperation, keyword co-occurrence, and keyword clustering analysis.Results:A total of 349 articles were included, including 237 Chinese articles and 112 English articles. According to the search results of CNKI, there were 161 institutions publishing article related to early rehabilitation for patients with severe neurological diseases in China, among which the Nursing Department of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medicine School had the highest number of publications (4 articles) . The search results of the Web of Science showed that there were 160 institutions publishing article in this field, among which the Florey Institute of Neuroscience and Mental Health in Australia in Australia had the highest number of publications (16 articles) . Foreign researchers mainly focused on the safety assessment and timing of early rehabilitation for patients with severe neurological diseases, while domestic research mainly focused on the evaluation of the effectiveness of different rehabilitation methods on early rehabilitation for patients with severe neurological diseases.Conclusions:The research on early rehabilitation of patients with severe neurological diseases in foreign countries is more in-depth and comprehensive than in China, and there are more multi-center clinical studies, providing a high-level evidence for clinical decision-making. On the basis of existing research results, domestic scholars should focus on strengthening interdisciplinary and inter institutional cooperation, improving the quality and effectiveness of rehabilitation, and fully leveraging the leading role of nurses while collaborating across multiple disciplines.

PURPOSE: Venous thromboembolism (VTE) is a major health issue among hip fracture patients. This study aimed to develop an information platform based on a mobile application and then evaluate whether information platform-based nursing could improve patient's drug compliance and reduce the incidence of VTE in hip fracture patients. METHODS: This study retrospectively analyzed hip fracture patients who were treated with conventional prevention and intervention methods for VTE (control group) between January 2008 and November 2012, and prospectively analyzed hip fracture patients who were treated with nursing intervention based on the information platform (study group) between January 2016 and September 2017. All the patients included in the both groups were hip fracture patients who had an age over 50 years, treated with surgery, and hospitalized ≥ 48 h. Patients were excluded if they admitted to hospital due to old fractures, had a severe bleeding after 72 h of admission, diagnosed with any type of VTE, or refused to participate in the study. The information platform was divided into medical, nursing, and patient interface. Based on the information platform, medical practitioners and nurses could perform risk assessments, monitoring management and early warnings, preventions and treatments, health educations, follow-up, and other aspects of nursing interventions for patients. This study compared essential characteristics, drug compliance, VTE occurrence, and mean length of hospitalization between the two groups. Besides, a subgroup analysis was performed in the study group according to different drug compliances. SPSS 18.0 software (IBM Corp., NY, and USA) was used for statistical analysis. RESULTS: Altogether 1177 patients were included in the control group, and 491 patients in the study group. Regarding baseline data, patients in the study group had more morbidities than those in the control group (p < 0.05). The difference of drug compliance between the two groups was statistically significant (p < 0.001): 761 (64.7%) of the patients in the control group and only 30 (6.1%) patients in the study group had poor drug compliance. In terms of VTE, 10.7% patients (126/1177) in the control group had VTE, and the rate in the study group was 7.1% (35/491), showing a statistically significant difference (p = 0.02). Moreover, the average length of hospitalization in the study group was also significantly lower than that in the control group (10.4 days vs. 13.7 days, p < 0.001). Subgroup analyses of the study group showed that the incidence of VTE in patients with poor, partial, and good compliances were 56.7% (17/30), 5.8% (10/171), and 2.8% (8/290), respectively, revealing a significantly huge difference (p < 0.001). CONCLUSIONS Poor drug compliance leads to higher VTE occurrence. The information platform-based nursing can effectively improve the compliance of hip fracture patients and thus considerably reduce the incidence of VTE. The mobile application may be an effective tool to prevent VTE in hip fracture patients.

The aim of this study is to apply 3D printing technology to hospital drug dosing operations, and explore its feasibility and scalability. Drugs often dosed in hospitals are selected as models. The commercially available drug was ground into powder, diluted with medicinal excipients and then mixed with 75% ethanol and binder to prepare a paste for 3D printing. The dose and physicochemical properties of divided tablets were controlled by setting print parameters and printing models in computer software. Different 3D printers were employed to evaluate the impact of the device on the dosing tablet. Two drugs were dosed in this study to explore the scalability of 3D printing technology between different drugs. The drug content of the three divided dose tablets (warfarin sodium 1 mg, 2 mg, hydrochlorothiazide 5 mg) was 1.02±0.03, 1.96±0.01, 5.19±0.06 mg. The content uniformity was 1.0, 5.3, 2.6, respectively. The drug dissolution rate was (99.3±1.2)%, (101.5±0.3)%, (98.1±0.8)% in 45, 45 and 30 min. The mechanical properties of the three sub-doses and the stability within 30 days were in line with the Chinese Pharmacopoeia (2015) requirements. At the same time, it was found that the printing parameters and prescriptions can affect the properties of the divided dose tablets. By controlling the dilution ratio of commercial drug and printing parameters, the drug release rate can be customized to achieve individualized treatment. Both different modes of 3D printers can produce qualified sub-doses, and 3D print dispensing technology was also versatile between the two drugs. 3D printing can prepare small-volume, high-precision, high-repetition dosing tablets, with all properties in compliance with pharmacopoeia regulations. Thus, this method can be used as a new and scalable sub-dosing method.

Objective: To investigate the impact of FLT3-ITD and DNMT3A R882 double mutations to the prognosis of acute myeloid leukemia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: FLT3-ITD, DNMT3A, C-kit, CEBPA, FLT3-TKD and NPM1 mutations were detected in 206 newly diagnosed AML patients by Sanger sequencing (M(3) and those received FLT3 inhibitor were excluded). Clinical data of AML patients were retrospectively analyzed to compare the prognosis of each gene mutation group. Results: ①Of 206 patients, 104 were male and 102 female with a median age of 38 (3-63) years, including 6 cases of M(0), 24 cases of M(1), 56 cases of M(2), 39 cases of M(4), 63 cases of M(5), 6 cases of M(6) and 12 unclassified cases. ②All 206 patients were divided into four groups according to the mutation gene at the time of diagnosis: FLT3-ITD(+) DNMT3A R882(+) group (group A), FLT3-ITD(+) DNMT3A R882(-) group (group B), FLT3-ITD(-) DNMT3A R882(+) group (group C) and FLT3-ITD(-) DNMT3A R882(-) groups (group D). Gender, leukocyte count at diagnosis, chromosome karyotype, the median age, FAB classification, disease status prior to transplantation, type of donor, conditioning regimen and GVHD were not significantly different between four groups (P>0.05). ③The 2-year cumulative recurrence rate (CIR) of group A was significantly higher than that of other groups [group A (72.2±2.6)%, group B (38.6±0.6)%, group C (36.8±1.6)%, group D (27.8±0.1)%, respectively, P<0.05], while the 2-year overall survival (OS) rate and 2-year leukocyte-free survival (LFS) rate were lower than those of other groups [group A (30.9±13.3)%, (11.3±10.2)%; group B (67.5±7.8)%, (47.9±8.4)%; group C (61.4±12.4)%, (56.8±12.5)%; group D (80.1±3.7)%, (79.7±3.6)%, respectively, P<0.05]. Conclusion: AML patients with FLT3-ITD and DNMT3A R882 double mutations had a very high CIR and low OS, LFS after transplantation.
