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 Consolidated Standards of Reporting Trials (CONSORT) statement aims to enhance the quality of reporting for randomized controlled trial (RCT) by providing a minimum item checklist. It was first published in 1996, and updated in 2001 and 2010, respectively. The latest version was released in April 2025, continuously reflecting new evidence, methodological advancements, and user feedback. CONSORT 2025 includes 30 essential checklist items and a template for a participant flow diagram. The main changes to the checklist include the addition of 7 items, revision of 3 items, and deletion of 1 item, as well as the integration of multiple key extensions. This article provides a comprehensive interpretation of the statement, aiming to help clinical trial staff, journal editors, and reviewers fully understand the essence of CONSORT 2025, correctly apply it in writing RCT reports and evaluating RCT quality, and provide guidance for conducting high-level RCT research in China.

Objective To explore the longitudinal associations of body roundness index (BRI), visceral adiposity index (VAI), and metabolic score for visceral fat (METS-VF) with the risk of new-onset atrial fibrillation (AF). Methods This study included participants from the UK Biobank who were free of AF or pregnancy at baseline and completed the first and second assessments of BRI, VAI, and METS-VF. The changes in BRI, VAI, and METS-VF were classified using K-means clustering analyses, and the cumulative adiposity indices were also calculated. The primary outcome was new-onset AF. Three Cox regression models were employed to investigate the longitudinal associations of the BRI, VAI, and METS-VF changes with the risk of incident new-onset AF. The results were presented as hazard ratios (HRs) and the corresponding 95% confidence intervals (CIs). Restricted cubic spline analyses were performed to explore potential non-linear associations between baseline or cumulative adiposity indices and the risk of new-onset AF. C-index analyses were conducted to evaluate the predictive value of BRI, VAI, and METS-VF for new-onset AF. Subgroup analyses were performed according to age, gender, race, smoking status, alcohol consumption, and physical activity. Polygenic risk scores were applied to account for genetic susceptibility and investigate potential interactions between adiposity indices and genetic risk. Univariate linear regression analyses were performed to evaluate the relationships of cumulative adiposity indices and magnetic resonance imaging and dual X-ray absorptiometry parameters, including visceral adipose tissue (VAT) volume, VAT mass, trunk fat volume, and trunk fat mass. We further applied the eXtreme Gradient Boosting (XGBoost) algorithm, with the feature importance being measured to evaluate the predictive value of each adiposity index for imaging parameters. Mendelian randomization analysis was further conducted to investigate the potential causal relationship between trunk fat mass and AF. Results A total of 12 776 participants were included. Over a median follow-up of 9.60 years, 761 (5.96%) new-onset AF events were recorded. Participants were divided into four classes based on the changes in adiposity indices. In the fully adjusted model, compared to participants in Class 1 of BRI, those in Class 3 (HR＝1.30, 95%CI 1.04-1.63, P＝0.023) and Class 4 (HR＝2.17, 95%CI 1.61-2.93, P＜0.001) were associated with significantly higher risks of new-onset AF. Regarding METS-VF, participants in Class 4 of METS-VF also demonstrated a significantly higher risk of new-onset AF compared to those in Class 1 (HR＝1.66, 95%CI 1.15-2.39, P＝0.007). However, no significant association was observed between different classes of VAI and the risk of new-onset AF. For every 1 standard deviation increase in cumulative BRI, VAI, and METS-VF, the fully adjusted HRs of new-onset AF were 1.23 (95%CI 1.13-1.35), 1.02 (95%CI 0.94-1.10), and 1.23 (95%CI 1.12-1.35), respectively. Cumulative adiposity indices (BRI, VAI, and METS-VF) were divided into quartiles. Using the first quartile as reference, participants in the highest quartiles of BRI (HR＝1.40, 95%CI 1.10-1.79, P＝0.007) and METS-VF (HR＝1.44, 95%CI 1.13-1.83, P＝0.003) both exerted a significantly higher risk of new-onset AF. Regarding VAI, no significant association was observed (HR＝1.00, 95%CI 0.81-1.23, P＝0.988). Restricted cubic spline analyses revealed non-linear relationships between cumulative BRI, baseline/cumulative VAI, and baseline/cumulative METS-VF with new-onset AF risk (all P_overall＜0.05, P_non-linear＜0.05). In the C-index analysis, BRI demonstrated the highest predictive performance for new-onset AF, followed by METS-VF and VAI. Subgroup analysis indicated a stronger association between METS-VF and the risk of new-onset AF amongst participants younger than 60 years (P_interaction＝0.008). Polygenic risk score analysis stratified by genetic risk demonstrated a synergistic effect between BRI and genetic risk with new-onset AF, with the overall risk of new-onset AF increasing as both BRI and genetic risk increased. Linear regression analysis revealed a positive correlation between cumulative BRI with VAT volume, VAT mass, trunk fat volume, and trunk fat mass. The feature importance plot derived from the XGBoost algorithm indicated that cumulative BRI had the greatest predictive value on VAT volume, VAT mass, trunk fat volume, and trunk fat mass. Mendelian randomization analysis confirmed a significant causal relationship between trunk fat mass and AF. Conclusions There are significant non-linear associations between BRI, METS-VF, and VAI with new-onset AF. Higher BRI and METS-VF are significantly associated with a higher risk of new-onset AF, whereas no significant association is observed for the VAI. BRI exhibits a positive correlation with VAT and trunk fat, and demonstrates superior performance in predicting new-onset AF compared to VAI and METS-VF. Monitoring and managing BRI may be important in the early detection and intervention of AF.

Objective To preliminarily evaluate the safety and effectiveness of a novel non-implantable atrial shunt device based on radiofrequency ablation for the treatment of chronic heart failure(CHF).Methods This was a prospective single-arm study.From January 2023 to December 2023,five eligible CHF patients were consecutively enrolled at Beijing Anzhen Hospital,Capital Medical University,and underwent inter-atrial shunt using Shenzhen Betterway atrial shunt device.Pulmonary capillary wedge pressure(PCWP),right atrial pressure(RAP),pulmonary artery pressure(PAP),total pulmonary resistance(TPR),pulmonary vascular resistance(PVR),and pulmonary/systemic blood flow ratio(Qp/Qs)were measured using right heart catheterization before and immediately after procedure.Patients were followed up for 90 days,and echocardiography,right heart catheterization,and cardiac functional indicators were evaluated.The primary endpoint was procedural success.Secondary endpoints included clinical success,echocardiographic changes,6-minute walk distance(6MWD)changes,New York Heart Association(NYHA)class changes,Kansas city cardiomyopathy questionnaire(KCCQ)score changes,and amino-terminal probrain natriuretic peptide(NT-proBNP)level changes at 90 days.The safety endpoint was major cardiovascular and cerebrovascular adverse events and device-related adverse events.Results All five patients successfully achieved left-to-right atrial shunt.Compared with baseline,PCWP decreased significantly immediately after procedure in all five patients,with a procedural success rate of 100％.There were no significant changes in RAP,PAP,TPR,and PVR before and immediately after procedure.After 90 days follow-up,four patients had persistent left-to-right atrial shunt,and PCWP was significantly lower than baseline,with a clinical success rate of 80％.Compared with baseline,LVEF increased,left ventricular end-diastolic diameter decreased,and tricuspid annular plane systolic excursion and right ventricular fractional area change were not impaired in all five patients at 90 days.KCCQ scores and 6MWT improved,NT-proBNP decreased,and NYHA class did not change significantly.There were no deaths,rehospitalizations for heart failure,stroke-related adverse events,or device-related adverse events during the follow-up.Conclusions The novel non-implantable atrial shunt catheter can safely and effectively improve hemodynamic,echocardiographic,and cardiac functional indicators in patients with heart failure.However,larger-scale clinical studies are still needed to validate its long-term clinical effectiveness.

The objective of this study was to determine the frequency and resistance patterns of ESBL-producing E.coli in lambs with diarrhea in the Kashi area,Xinjiang.The findings may provide guidance for the prevention and control of clinical E.coli disease.We collected 385 samples of perianal feces from lambs with diarrhea in the Kashgar area.From these samples,we isolated 371 strains of E.coli.We then used the double-paper-sheet synergistic method to screen for ESBL-producing E.coli.Additionally,we conducted analyses to identify drug-resistance genes,analyze drug resistance,and study the phylo-typing of the screened strains.Of 371 E.coli strains,204 were identified as ESBL-producing strains.The prevalence rates of blaCTX-M,blaCTX-M-1G,blaCTX-M-9G,and bla TEM resistance genes was 67.65％,69.12％,30.39％,and 63.73％,respectively.All ESBL-pro-ducing strains were resistant to multiple drugs,with resistance rates ranging from 90.69％to 100％for eight specific drugs:ampicillin,cefotaxime,gentamicin,enrofloxacin,azithromy-cin,tetracycline,chloramphenicol,methotrexate,and amitrazine.The phylogenetic subgroups of the strains were distributed primarily in groups A and D.Among group A strains,41.11％exhibited resistance to ten drugs,whereas among group D strains,40％exhibited resistance to 11 drugs.ESBL-pro-ducing strains of Escherichia coli are the main pathogens cau-sing diarrhea in lambs in the Kashgar region;group A is the main group,and all groups are multi-drug resistant.

Objective:To observe the clinical and imaging features of patients with retinal vein occlusion (RVO) complicated with retinal artery occlusion (RAO).Methods:A retrospective clinical study. Fifteen patients with 15 eyes with RVO combined with RAO and macular edema diagnosed by ophthalmology examination in the Department of Ophthalmology, First People's Hospital of Xianyang City during 2 years from February 1, 2022 to January 31, 2024 were included in the study. Branch retinal vein occlusion (BRVO) combined with branch retinal artery occlusion (BRAO) occurred in 3 cases and 3 eyes. Central retinal vein occlusion (CRVO) complicated with central retinal artery occlusion (CRAO) in 12 eyes. Best corrected visual acuity (BCVA), intraocular pressure, scanning laser ophthalmoscope, optical coherence tomography (OCT), fluorescein fundus angiography (FFA) and serum homocysteine were all performed. OCT angiography (OCTA) was performed in 6 eyes. All eyes were treated with intravitreal injection of anti-vascular endothelial growth factor drugs. After the initial 1 treatment, dosage was assessed as needed. Follow-up was performed every month for 12 months after treatment. FFA inspection was performed at 3 months. During follow-up, it was found that there were no perfusion areas of capillaries, and retinal laser photocoagulation therapy was given in time. Fundus manifestations, FFA, OCT, OCTA characteristics and causes of disease were analyzed retrospectively.Results:There were 15 eyes in 15 cases, 9 eyes in 9 males; 6 women with 6 eyes. Age was (61.0±9.7) years. All complained of painless vision loss in one eye. All eyes were positive for relative afferent pupillary disorder. Contralateral congenital optic disc defect was in 1 case; hypertension was in 6 cases; hyperhomocysteinemia was in 2 cases; cerebral infarction was in 3 cases; coronary heart disease was in 1 case. CRVO combined with CRAO was in 12 eyes BCVA light sensitivity-0.25. The BCVA of BRVO combined with BRAO were 0.1, 0.4 and 0.25, respectively. All the patients had retinal edema in the posterior pole of the eye, venous sinuous, dilated, thin arteries and stiff shape. The retina presents with flaky or flame-like bleeding. Posterior polar retinal lint patch was in 13 eyes. In 12 eyes with CRVO combined with CRAO, optic disc edema was observed and the boundary was not clear. In 3 eyes with BRVO combined with BRAO, no obvious abnormality was found in the optic disc, and the boundary was clear. FFA examination showed no or prolonged arterial filling, delayed retinal vein laminar flow, relatively slow or even no capillary filling, macular arteriole atretosis to varying degrees, arch ring structure destruction, optic disc telangiectasia and fluorescein leakage. OCT examination showed that the middle and inner layers of the retina were thickened to varying degrees, the diffuse reflex was enhanced, the interlayer structure was unclear, and the reflex of the lower retinal tissue was weakened. The blood flow density of superficial capillary plexus and deep capillary plexus (DCP) decreased in 6 eyes undergoing OCTA examination. Decreased or interrupted blood flow in the vascular bed of DCP. During the follow-up period, there were 13 eyes with no perfusion area of retinal capillary. The time of occurrence was (1.14±0.95) (0-2) months, and the area was 10-75 disc area. Optic nerve atrophy occurred in 5 eyes. At the last follow-up, visual acuity increased, unchanged and decreased in 12, 2 and 1 eyes, respectively.Conclusions:The pathogenesis of RVO-RAO is complicated. Most RVO and RAO occurred simultaneously, and a few RVO occurred several days after RAO. Although the RAO manifestations are not typical, the radiographic features are both RVO and RAO. Compared with BVRO combined with BRAO, the prognosis of visual acuity in CRAO patients with CRVO is worse.

Inguinal hernia is one of the most common surgical diseases, mainly in men and elderly people, and its occurrence and development are related to many risk factors. At present, inguinal hernia can only be cured with surgery, which requires the selection of surgical methods based on patients′ conditions, medical resources and surgeons′ skills. With the aging of the popula-tion, it is expected that the number of inguinal hernia patients will continue to increase. The authors review the epidemiology, risk factors and characteristics of surgical treatment mode of inguinal hernia based on the epidemiological studies of inguinal hernia in recent years.

Objective:To construct a novel dual-specific antibody targeting human CD123 (CD123 DuAb) and study its effects in acute myeloid leukemia (AML) .Methods:Based on the variable region of the CD123 monoclonal antibody independently developed at our institution, the CD123 DuAb expression plasmid was constructed by molecular cloning and transfected into ExpiCHO-S cells to prepare the antibody protein. Through a series of in vitro experiments, its activation and proliferation effect on T cells, as well as the effect of promoting T-cell killing of AML cells, were verified.Results:① A novel CD123 DuAb plasmid targeting CD123 was successfully constructed and expressed in the Expi-CHO eukaryotic system. ②The CD123 DuAb could bind both CD3 on T cells and CD123 on CD123 + tumor cells. ③When T cells were co-cultured with MV4-11 cells with addition of the CD123 DuAb at a concentration of 1 nmol/L, the positive expression rates of CD69 and CD25 on T cells were 68.0% and 44.3%, respectively, which were significantly higher than those of the control group ( P<0.05). ④Co-culture with CD123 DuAb at 1 nmol/L promoted T-cell proliferation, and the absolute T-cell count increased from 5×10 5/ml to 3.2×10 6/ml on day 9, and CFSE fluorescence intensity decreased significantly. ⑤ With the increase in CD123 DuAb concentration in the culture system, T-cell exhaustion and apoptosis increased. When the CD123 DuAb was added at a concentration of 1 nmol/L to the culture system, the proportion of CD8 + PD-1 + LAG-3 + T cells was 10.90%, and the proportion of propidium iodide (PI) - Annexin Ⅴ + T cells and PI + Annexin Ⅴ + T cells was 18.27% and 11.43%, respectively, which were significantly higher than those in the control group ( P<0.05). ⑥ The CD123 DuAb significantly activated T cells, and the activation intensity was positively correlated with its concentration. The expression rate of CD107a on T cells reached 16.05% with 1 nmol/L CD123 DuAb, which was significantly higher than that of the control group ( P<0.05). ⑦The CD123 DuAb promoted cytokine secretion by T cells at a concentration of 1 nmol/L, and the concentration of IFN-γ and TNF-α in the supernatant of the co-culture system reached 193.8 pg/ml and 169.8 pg/ml, respectively, which was significantly higher than that of the control group ( P<0.05). ⑧When CD123 DuAb was added at a concentration of 1 nmol/L to the co-culture system of T cells and CD123 + tumor cells, the killing intensity of T cells significantly increased, and the residual rates of CD123 + MV4-11 cells, CD123 + Molm13 cells, and CD123 + THP-1 cells were 7.4%, 6.7%, and 14.6% on day 3, respectively, which were significantly lower than those in the control group ( P<0.05) . Conclusion:In this study, a novel CD123 DuAb was constructed and expressed. In vitro experiments verified that the DuAb binds to CD123 + tumor cells and T cells simultaneously, promotes T-cell activation and proliferation, and facilitates their anti-leukemia effect, which provides a basis for further clinical research.

Cognitive dysfunction refers to dysfunction of individual perception,memory,understanding,learning,creation and other dysfunctions caused by abnormal brain function and structure.Based on the fact that the spleen can't regulate transportation and transformation,govern blood and send up essential substance,combined with the microbiota-gut-brain axis,this article discussed the etiology and pathogenesis of intestinal flora imbalance affecting cognitive dysfunction in TCM.It was proposed that the spleen in TCM and intestinal flora are connected in physiology and pathology:the spleen regulates spirit and governs cognition,when the spleen fails to function normally that it can't dominate transportation and transformation,govern blood and send up essential substance will cause that the brain spirit can not be nourished;intestinal flora is closely related to the spleen in TCM,and affects brain function through the nervous system,endocrine,immune and metabolic mechanisms.This article can provide explore new ideas for the clinical research and treatment of cognitive dysfunction of traditional Chinese and Western medicine.

Objective To construct a diagnostic model for the phlegm-dampness obstruction syndrome in patients with coronary heart disease stable angina pectoris(CSAP);To provide a reference for clinical syndrome differentiation.Methods Totally 305 patients'clinical data were collected from the Department of Cardiology,Dongying Hospital Affiliated to Shandong University of Traditional Chinese Medicine,from May 2022 to January 2024.The least absolute shrinkage and selection operator(LASSO)was used to select features,and multiple models were constructed and compared using machine learning(ML)algorithms.The optimal ML model was selected for training,validation,and testing.Finally,the operational logic of the optimal model was explained using Shapley Additive Explanations(SHAP),and two typical examples were provided to help users understand the model's operational logic.Results LASSO regression identified chest pain,body mass index(BMI),limb heaviness,drinking history,age,triglycerides(TG),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)as features included in the model.After comparing multiple models,the Gaussian Naive Bayes(GNB)model demonstrated the best performance.The final constructed GNB model achieved an average AUC of 0.938(95%CI:0.903-0.972)in the training set,an average AUC of 0.927(95%CI:0.851-0.992)in the validation set,and an AUC of 0.856(95%CI:0.751-0.961)in the test set.The learning curve showed that the error between the training and validation sets in the model converged as the number of training samples increased.The calibration curve showed that the model had good consistency in predicting the probability of observed phlegm-dampness obstruction syndrome patients.The clinical decision curve(DCA)showed that the model could provide clinical benefits for patients at a decision threshold below 0.7.The features ranked by SHAP importance in order were chest pain,BMI,LDL-C,TG,limb heaviness,TC,drinking history and age.Conclusion The diagnostic model for CSAP phlegm-dampness obstruction syndrome constructed in this study can assist physicians in the syndrome differentiation of patients,thereby enabling the formulation of integrated clinical treatment plans combining traditional Chinese and Western medicine,and aiding patients in achieving better clinical therapeutic outcomes.
