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 incidence of myopia among Chinese adolescents is progressively rising, indicating a distinct trend toward younger age onset.This paper aims to comprehensively review the impact of various visual performance on myopia and its progression, with a specific emphasis on accommodative function, convergence function, and ocular position. A meticulous exploration of accommodation function, encompassing accommodative amplitude, accommodative facility, accommodative response, positive relative accommodation, and negative relative accommodation, has been undertaken to elucidate its contributory role in myopia progression. Concurrently, an exhaustive analysis of convergence function has been conducted including esotropia and exotropia, convergence insufficiency and convergence excess, fusional function vergence, divergence insufficiency, and excess, providing a nuanced understanding of convergence's implications for myopia advancement. Furthermore, the influence of ocular position on myopia progression, along with other factors affecting perceptual ocular position and intermittent exotropia, is discussed. The primary objective of this article is to unveil the multifaceted visual performance influencing myopia and its progression, elucidating the paramount significance of accommodative function, convergence function, and ocular position in this context.

To understand Helicobacter pylori's drug resistance,genetic diversity,and relationship with clinical diseases in the Guiyang and Qiannan minority areas of Guizhou Province,we collected samples through endoscopy,and isolated and cul-tured H.pylori.The drug resistance and genotype characteristics were determined.The differences in different regions and dis-ease types were compared,and the structural characteristics of H.pylori and mixed infections with different strains of H.py-lori in Qiannan Prefecture were analyzed.A difference in the composition ratio of EPYIA typing in the cagA variable region was observed between the two areas(P=0.012),and the composition ratio of the vacA genotype differed(P=0.000).A total of 94.6％(53/56)new sequences of H.pylori strains from two regions were obtained by MLST.The rate of infection by H.pylori mixed with different strains was 44.4％in Qiannan Pre-fecture,and no significant difference was observed in the com-position of H.pylori mixed infections among patients with dif-ferent clinical diseases(P=0.349).Differences in EPI YA typ-ing and the vacA genotype composition ratio in the cagA varia-ble region of H.pylori were observed between the Qiannan Prefecture and Guiyang City.

Objective To explore the effect of Shugan Lipi decoction on inflammation and intestinal flora,Toll like receptor 4(TLR4),T cell immunoglobulin domain and mucin domain-3(Tim-3)in non-alcoholic steatohepatitis(NASH)rats.Methods The NASH model was established by feeding methionine and choline deficient diet for 4 weeks.SD rats were randomly divided into blank group(intragastric administration with 0.9％NaCl),model group(NASH model,intragastric administration with 0.9％NaCl),and experimental group(NASH model,intragastric administration with 6.18g·kg-1 Shugan Lipi decoction).Illumina sequencing by synthesis method was used to detect the 16S rRNA sequence of rat Intestinal microbiota.Western blot method was used to detect the expression levels of Tim-3 and TLR4 proteins.Enzyme-linked immunosorbent assay was used to detect tumor necrosis factor-α(TNF-α),interleukin(IL)-6 and IL-10 levels in each group of rats.Results After 4 weeks of medication,the relative abundance of Bacteroidetes in the blank,model and experimental groups were(47.96±10.52)％,(42.90±15.01)％and(57.15±10.99)％;the relative abundance of Firmicutes were(49.27±9.99)％,(53.06±11.47)％and(39.99±11.88)％;the relative expression levels of Tim-3 protein were 1.03±0.07,0.24±0.06 and 1.57±0.11;the relative expression levels of TLR4 protein were 1.04±0.11,3.23±0.33 and 0.94±0.27;the levels of TNF-α were(403.03±25.25),(576.87±60.29)and(385.16±37.67)pg·mL-1;the levels of IL-6 were(125.35±14.07),(189.75±34.30)and(113.71±18.35)pg·mL-1;the levels of IL-10 were(123.20±15.96),(66.71±11.94)and(119.54±10.57)pg·mL-1,respectively.The above indexes in the experimental group showed statistically significant differences compared with the model group(P＜0.01,P＜0.05).Conclusion Shugan Lipi decoction may regulate inflammatory cytokines by affecting intestinal flora and TLR4,Tim-3 protein expression,affect liver inflammatory response,and improve NASH.

Objective:To analyze the association between waist circumference (WC) and ischemic stroke (IS).Methods:The data for the present study were from the prospective cohort study of China Kadoorie Biobank in Qingdao. Using baseline information and IS events of the participants, the Cox proportional hazard regression model and restricted cubic spline (RCS) were used to analyze the association between WC and IS.Results:A total of 33 355 participants were included in the study, with 302 008.88 person-years of follow-up. A total of 1 093 new cases of IS were observed. Multivariate Cox proportional hazard regression model analysis showed that compared to the respondents with normal WC (male <85.0 cm, female <80.0 cm), respondents with excessive WC (male ≥85.0 cm, female ≥80.0 cm) had a 78% higher risk of IS incidence [hazard ratio( HR)=1.78, 95% CI: 1.51-2.10], and the risk increased by 72% ( HR=1.72, 95% CI: 1.40-2.12) and 83% ( HR=1.83, 95% CI: 1.40-2.39) in men and women. According to the RCS, the increase in WC and the risk of IS showed an "S" trend of nonlinear dose-response relationship. Conclusions:The risk of IS would increase with the WC. Keeping a normal WC is important for preventing IS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To evaluate the safety and efficacy of 225Ac-prostate specific membrane antigen (PSMA) in the treatment of metastatic castration-resistant prostate cancer (mCRPC). Methods:Eleven patients (age (70.0±8.8) years) with mCRPC who were treated with 225Ac-PSMA-617 between July 2021 and October 2023 in the Affiliated Hospital of Southwest Medical University were retrospectively analyzed. In order to assess efficacy, the Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria were used to evaluate the changes in prostate specific antigen (PSA) level after the treatment. 68Ga-PSMA-11 PET/CT imaging was performed at the baseline and after the treatment, and molecular imaging response was assessed using the modified PET response criteria in solid tumors (PERCIST) 1.0. Progression-free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Toxicity was assessed by common terminology criteria for adverse events version 5.0 (CTCAE 5.0). The paired t test or Wilcoxon signed rank test was used to compare the parameters before and after treatment. Results:Post-treatment PSA levels were significantly lower than pre-treatment in 9 of 11 patients (17.83(4.74, 41.25) vs 124.33(77.85, 784.22) μg/L; z=-2.67, P=0.008), and 6 of them decreasing by more than 50% and 2 patients experienced progressive disease (PD) with PSA levels rising by more than 25%. Post-treatment 68Ga-PSMA-11 PET/CT showed that 7 patients achieved partial response (PR), 2 patients achieved stable disease (SD), and 2 patients were with PD. The OS was 12.0(10.0, 18.0) months and PFS was 8.0(6.0, 11.0) months in 11 patients. There were no statistically significant differences after therapy in WBC counts, Hb, PLT, creatinine, glomerular filtration rate, alanine aminotransferase, aspartate aminotransferase, total bilirubin ( z values: from -1.07 to 0.00, t values: from -0.77 to 1.76, all P>0.05). No grade Ⅲ/Ⅳ nephrotoxicity or salivary gland toxicity was observed. Conclusion:225Ac-PSMA-617 is a promising novel therapeutic option for mCRPC with favorable safety and tolerability.

Objective To observe the therapeutic effect and mechanism of Baoyuan Decoction for chronic heart failure model rat.Methods SD rats were randomly divided into blank group,model group,Baoyuan Decoction group,Captopril group,Baoyuan Decoction+CCT020312[protein kinase R-like endoplasmic reticulum kinase(PERK)activator]group,15 rats in each group.Except for the blank group,the rats in the other groups were induced by Adriamycin to construct a chronic heart failure model.After corresponding drug intervention,cardiac function indexes[left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF),left ventricular fractional shortening(LVFS),brain natriuretic peptide(BNP),cardiac troponin I(cTnI)],inflammation-related factors[tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β)],oxidative stress factors[malondialdehyde(MDA),superoxide dismutase(SOD)]were detected in each group.Changes in apoptosis-related indicators[B-cell lymphoma 2(Bcl-2),B-cell lymphoma 2-associated X protein(Bax),Caspase-3]and PERK/transcription activator 4(ATF4)signaling pathway-related proteins glucose-regulated protein 78(GRP78),PERK,ATF4,C/EBP homologous protein(CHOP)levels.Results Compared with the blank group,LVEDD,BNP,cTnI,TNF-α,IL-1β,MDA levels,protein expression levels of Bax,Caspase-3,GRP78,PERK,ATF4,CHOP in the model group were significantly increased,LVEF,LVFS,SOD levels and Bcl-2 protein expression level were significantly decreased(all P＜0.05).Compared with the model group and Baoyuan Decoction+CCT020312 group,LVEDD,BNP,cTnI,TNF-α,IL-1β,MDA levels,protein expression levels of Bax,Caspase-3,GRP78,PERK,ATF4,CHOP in Baoyuan Decoction group and Captopril group were significantly decreased,LVEF,LVFS,SOD levels and Bcl-2 protein expression level were significantly increased(all P＜0.05).Compared with the Captopril group,there was no significant change in the above indexes(except CHOP protein expression level)in the Baoyuan Decoction group(P＞0.05).Conclusion Baoyuan Decoction can delay the progression of chronic heart failure rats,and its mechanism may be related to inhibiting the PERK/ATF4 signaling pathway to alleviate cardiomyocyte apoptosis,further reducing the degree of inflammatory response and oxidative stress,thereby promoting the repair of cardiac function and myocardial injury.

Cell cycle analysis is essential for determining the cell proliferation state,studying cell func-tions,and evaluating drug effects.Flow cytometry is a commonly used method for cell cycle detection,with propidium iodide(PI)being the most widely used fluorescein.Nevertheless,various factors may af-fect the test results.Additionally,comparing distributions of immune cell subpopulations across different cell cycle stages can provide valuable insights into immunological responses and disease conditions.In this research,the B16-F10 cell line was used to study the impact of three factors on PI staining-based cell cycle detection:fixation settings,sample preparation conditions,and software analysis.To fix cells,it is suggested to suspend 3 × 106 cells in 300 μL of pre-cooled PBS,add 700 μL of 100％ethanol drop-wise,fix overnight at 4℃ or-20℃,and collect at a low flow rate(400-600 events/s)to ensure collec-tion of at least 3 000 singlets.Furthermore,dual-labeling with 5-ethynyl-2'-deoxyuridine(EdU)and PI can accurately distinguish cell cycle phases.And various immune cell subpopulations can be analyzed without cell sorting by combining surface marker staining with PI and Ki-67 staining.Here we review fac-tors affecting cell cycle identification using the PI staining method and provide a standard operating proto-col for the experiment.We established the method to combine EdU with PI for cell cycle detection and a-nalysis of immune cell subpopulations,thus expanding the approaches for cell cycle detection.

This study aims to compare the chemical constituents in 24 batches of Artemisiae Argyi Folium samples collected from three different Dao-di producing areas(Anguo in Hebei, Nanyang in Henan, and Qichun in Hubei). An ultra-performance liquid chromatography(UPLC) method was established to determine the content of 13 nonvolatile components, and headspace-gas chromatography-mass spectrometry(HS-GC-MS) was employed for qualitative analysis and comparison of the volatile components. The content of phenolic acids in Artemisiae Argyi Folium was higher than that of flavonoids, and the content of nonvolatile components showed no significant differences among the samples from the three Dao-di producing areas. A total of 40 volatile components were identified, and the relative content of volatile components in Artemisiae Argyi Folium was significantly different among the samples from different Dao-di producing areas. The principal component analysis and partial least squares discriminant analysis identified 8 volatile components as the potential markers for discrimination of Artemisiae Argyi Folium samples from different Dao-di producing areas. This study revealed the differences in the chemical composition of Artemisiae Argyi Folium samples from three different Dao-di producing areas, providing analytical methods and a scientific basis for the discrimination and quality evaluation of Artemisia Argyi Folium in different Dao-di producing areas.
