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.

Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Objective To investigate the correlation between serum vascular endothelial growth factor(VEGF),Cystatin C(CysC),and retinol-binding protein(RBP)levels and the pathology and prognosis of chronic glomerulonephritis(CGN).Methods A total of 102 patients with CGN diagnosed and treated between June 2020 and August 2022 were selected as study participants and assigned to the observation group,which was divided according to pathological types into the mesangial proliferative nephritis(MSPGN,n=35),mesangial capillary glomerulonephritis(MPGN,n=23),membranous nephropathy(MN,n=23),and focal segmental glomerulosclerosis(FSGS,n=17)groups.Healthy subjects(n=51)were selected as the control group.Changes in serum VEGF,CysC,and RBP levels were compared,and the correlation between VEGF,CysC,and RBP levels and pathological scores was analyzed using the Pearson method.All patients were followed up for 12 months and divided according to prognoses into a progression group(n=28)and no progression/remission group(n=74).The effects of VEGF,CysC,and RBP levels on the prognosis of patients with CGN were analyzed using Cox multifactor risk regression.The area under the curve(AUC),sensitivity,and specificity of VEGF,CysC,RBP,and the combined prognoses of patients with CGN were analyzed using a receiver operating characteristic(ROC)curve.Results The VEGF,CysC,and RBP levels were higher in the observation group than in the control group(P<0.05).The VEGF,and CysC,levels in the FSGS group were higher than those in the MSPGN,MPGN,and MN groups(P<0.05).The level of RBP in FSGS group was higher than that in MSPGN group(P<0.05).Pearson correlation analysis showed that VEGF,CysC,and RBP levels were positively correlated with the pathological scores(P<0.05).The VEGF,CysC,and RBP levels were higher in the progression group than in the no progression/remission group(P<0.05).Multivariate Cox regression analysis showed that increased VEGF,CysC,and RBP levels were risk factors for the prognosis of patients with CGN(P<0.05).The ROC curve analysis showed that the AUC values predicted by VEGF,CysC,RBP,and the combination of the three were 0.828,0.844,0.760,and 0.940,respectively(P<0.05);sensitivity was 75.00%,71.40%,57.10%,and 89.30%,respectively,and specificity was 93.20%,93.20%,95.90%,and 89.20%,respectively.Conclusion Serum VEGF,CysC,and RBP are highly expressed in patients with CGN,and high pathological scores are associated with increased levels,thus also affecting patient prognosis.

Objective To observe the safety and effectiveness of single dose intravenous infusion of tranexamic acid(TX-A)in dual level posterior lumbar interbody fusion(PLIF),and to explore the changes and trends in perioperative white blood cell(WBC),erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP).Methods Between October 2020 and September 2022,46 patients with lumbar degenerative disease were treated with dual level PLIF,including 18 males and 28 females,with an average age of(60.24±10.68)years old,from 34 to 80 years old.They were divided into observation group and control group according to different treatment methods.There were 28 patients in the observation group,including 12 males and 16 females,with an average age of(61.04±9.03)years old.There were 3 cases with lumbar disc herniation(LDH),lumbar spinal stenosis(LSS)18 cases,lumbar spondylolisthesis(LS)7 cases.TXA(1 g/100 ml)was administered intravenously 15 min before skin incision after general anesthesia.The control group consisted of 18 patients,including 6 males and 12 females,with an average age of(59.00±13.04)years old.There were 5 cases with LDH,LSS 9 cases,LS 4 cases,and TXA was not used.The operation time,intraoperative bleeding volume,postoperative drainage volume,postoperative deep vein thrombosis(DVT),postoperative hospital stay,postoperative activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB),platelet(PLT),red blood cell(RBC),hemoglobin(HB),hematocrit(HCT),the first day,the fourth day,the seventh day and the last tested after operation WBC,ESR and CRP were recorded.Results The postop-erative wounds of the patients healed well and there was no DVT.46 patients were followed up from 3 to 6 months.The intraop-erative blood loss was 400.0(300.0,500.0)ml and the postoperative drainage was 260.0(220.0,450.0)ml in the observation group,which were lower than the control group[600.0(400.0,1000.0)ml,395.0(300.0,450.0)ml],P＜0.05.There was no significant difference between the two groups in operation time,postoperative hospital stay,postoperative APTT,PT,TT,FIB,PLT,RBC,HB,HCT,and postoperative WBC,ESR and CRP at different times(P＞0.05).Conclusion Single dose intravenous infusion of TXA can reduce the blood loss of bi-segmental PLIF,and has no significant effect on WBC,ESR and CRP after op-eration.

Hydrogen sulfide,as a third gas signal molecule and neurotransmitter,can play a neuroprotective role by anti-oxidative stress,anti-inflammatory response,metabolic inhibition and other mechanisms.It is of great significance for the occurrence and development of neurodegenerative diseases including Alzheimer's disease(AD)and Parkinson's disease(PD)mediated by neuroinflammation.This article reviews the research progress of hydrogen sulfide and neuroinflammation and its mediated neurodegenerative diseases,so as to provide new ideas for the treatment of neurodegenerative diseases.
