Objective: This study aimed to evaluate the prognostic value of [ 18F]ALF-NOTA-FAPI-04 PET/CT-derived parameters, including the maximum standardized uptake value (SUVmax), FAPI-avid tumor volume (FTV), and total lesion FAP expression (TLF), in patients with recurrent gastric cancer undergoing combined chemoimmunotherapy. We sought to establish a noninvasive imaging biomarker framework to optimize patient stratification and therapeutic decision-making. Materials and Methods: This retrospective cohort study analyzed 51 patients with recurrent gastric cancer who received programmed cell death protein 1 (PD-1) inhibitors combined with chemotherapy after gastrectomy. All patients underwent [ 18F]ALF-NOTA-FAPI-04 PET/CT within 14 days of chemoimmunotherapy. Semi-quantitative parameters (SUVmax, FTV, and TLF) were derived using semi-automated tumor segmentation. The primary endpoint of this study was the assessment of the clinical efficacy of chemoimmunotherapy, categorized as a durable or nondurable clinical benefit. The secondary endpoints included progression-free survival (PFS) and overall survival (OS). In a subgroup of 16 patients who underwent sequential [ 18F]FDG PET/CT within seven days of [ 18F]ALF-NOTA-FAPI-04 PET/CT, tracer uptake values were compared between the two PET/CT examinations. Results: 51 patients were included. The median PFS and OS were 7 and 10 months, respectively. Durable clinical benefit (DCB) was observed in 30 patients and showed significantly lower SUVmax, FTV, and TLF values than non-DCB. TLF demonstrated the highest diagnostic accuracy for DCB (area under the receiver operating characteristic curve [AUC] = 0.80). Multivariable analysis identified TLF ≥ 188.88 SUVbw·cm 3 as an independent factor associated with PFS (hazard ratio [HR] = 7.29, P = 0.001) and FTV ≥ 44.17 cm 3 as an independent factor associated with OS (HR = 5.16, P = 0.010). In the subgroup analysis of 16 patients, semi-quantitative analysis demonstrated consistently higher values of [ 18F]ALF-NOTA-FAPI-04-derived parameters than [ 18F]FDG-derived parameters (all P < 0.001). Conclusion [ 18F]ALF-NOTA-FAPI-04 PET/CT may be a useful imaging tool for predicting clinical outcomes in patients with recurrent gastric cancer undergoing treatment with PD-1 inhibitors and chemotherapy.

Objective To compare the efficacy and safety of transurethral blue laser vaporization of the prostate, transurethral resection of the prostate (TURP) or plasmakinetic resection of the prostate in the treatment of benign prostatic hyperplasia (BPH). Methods The domestic and foreign clinical studies on transurethral blue laser vaporization of the prostate (observation group), TURP or plasmakinetic resection of the prostate (control group) in the treatment of BPH during Jan. 2015 and Mar. 2025 were retrieved. The data were extracted with Cochrane systematic review method. The operation time, decrease in hemoglobin, bladder irrigation time, catheter indwelling time, total complication rate, retrograde ejaculation rate and urinary incontinence rate of the two groups were compared with RevMan 5.3.0 statistical software. Results A total of 5 Chinese studies involving 491 patients (248 in the observation group and 243 in the control group) were included in the Meta-analysis. Compared with the control group, the observation group had shorter operation time [MD=-20.80, 95%CI:-26.88—-14.72, P＜0.00001], less decrease in hemoglobin [MD=-10.61, 95%CI: -20.21—-1.01, P=0.03], shorter bladder irrigation time [MD=-17.85, 95%CI: -32.62—-3.09, P=0.002], shorter catheter indwelling time [MD=-1.71, 95%CI: -2.81—- 0.62, P=0.002], lower total complication rate [OR=0.11, 95%CI: 0.06—0.21, P＜0.00001], lower retrograde ejaculation rate [OR=0.05, 95%CI: 0.02—0.16, P＜0.00001] and lower urinary incontinence rate [OR=0.24, 95%CI: 0.07—0.79, P=0.02]. There were no significant differences in other complications between the two groups (P＞0.05). The international erectile function score (IIEF-5) of the observation group was significantly higher than that of the control group [MD=1.87, 95%CI:1.16—2.57, P＜0.00001]. There were no significant differences in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax) and post-voiding residual (PVR) between the two groups (P＞0.05). Conclusion All three surgical procedures can effectively improve the lower urinary tract symptoms of BPH patients. Compared with TURP or plasmakinetic resection of the prostate, transurethral blue laser vaporization of the prostate has obvious advantages in terms of perioperative recovery, reduction of total complications, urinary incontinence and retrograde ejaculation rates, and preservation of sexual function.

BACKGROUND: Chronic kidney disease (CKD)-associated anemia (CKD-anemia) is associated with poor survival, and hemoglobin targets are often not achieved with current therapies. Phase 3 trials have demonstrated the treatment efficacy of roxadustat for CKD-anemia. This phase 4 study aims to evaluate the long-term (52-week) safety and effectiveness of roxadustat in a broad real-world patient population with CKD-anemia with and without dialysis in China. METHODS: This Phase 4 multicenter, open-label, prospective study, conducted from 24 November 2020 to 11 November 2022, evaluated the long-term safety and effectiveness of roxadustat for CKD-anemia in China. Patients aged ≥18 years with CKD-anemia with or without dialysis were included. The initial oral dose was 70-120 mg (weight-based followed by dose adjustment) over 52 weeks. The primary endpoint was safety based on adverse events (AEs). The secondary endpoints were hemoglobin changes from baseline and the proportion of patients who achieved mean hemoglobin ≥100 g/L. Effectiveness evaluable populations 1 (EE1) and EE2 included roxadustat-naïve and previously roxadustat-treated patients, respectively. The safety analysis set (SAF) included all patients who received ≥1 occasion. RESULTS: The EE1, EE2, and SAF populations included 1804, 193, and 2021 patients, respectively. In the SAF, the mean age was 50 ± 14 years, and 1087 patients (53.8%) were male. Mean baseline hemoglobin was 96.9 ± 14.0 g/L in EE1 and 100.3 ± 12.9 g/L in EE2. In EE1, the mean (95% confidence interval) hemoglobin changes from baseline over weeks 24-36 and 36-52 were 14.2 (13.5-14.9) g/L and 14.3 (13.5-15.0) g/L, respectively. Over weeks 24-36 and 36-52, 83.3% and 86.1% of patients in EE1 and 82.7% and 84.7% in EE2 achieved mean hemoglobin ≥100 g/L, respectively. In the SAF, 1643 (81.3%) patients experienced treatment-emergent AEs (TEAEs). Overall, 219 (10.8%) patients experienced drug-related TEAEs. Thirty-eight (1.9%) patients died of TEAEs (unrelated to the study drug). Vascular access thrombosis was uncommon. CONCLUSIONS: Roxadustat (52 weeks) increased hemoglobin and maintained the treatment target in Chinese patients with CKD-anemia with acceptable safety, supporting its use in real-world settings.

Gut microbial communities are likely remodeled in tandem with accumulated physiological decline during aging, yet there is limited understanding of gut microbiome variation in advanced age. Here, we performed a metagenomics-based enterotype analysis in a geographically homogeneous cohort of 367 enrolled Chinese individuals between the ages of 60 and 94 years, with the goal of characterizing the gut microbiome of elderly individuals and identifying factors linked to enterotype variations. In addition to two adult-like enterotypes dominated by Bacteroides (ET-Bacteroides) and Prevotella (ET-Prevotella), we identified a novel enterotype dominated by Escherichia (ET-Escherichia), whose prevalence increased in advanced age. Our data demonstrated that age explained more of the variance in the gut microbiome than previously identified factors such as type 2 diabetes mellitus (T2DM) or diet. We characterized the distinct taxonomic and functional profiles of ET-Escherichia, and found the strongest cohesion and highest robustness of the microbial co-occurrence network in this enterotype, as well as the lowest species diversity. In addition, we carried out a series of correlation analyses and co-abundance network analyses, which showed that several factors were likely linked to the overabundance of Escherichia members, including advanced age, vegetable intake, and fruit intake. Overall, our data revealed an enterotype variation characterized by Escherichia enrichment in the elderly population. Considering the different age distribution of each enterotype, these findings provide new insights into the changes that occur in the gut microbiome with age and highlight the importance of microbiome-based stratification of elderly individuals.

JMJD1C (Jumonji Domain Containing 1C), a member of the lysine demethylase 3 (KDM3) family, is universally required for the survival of several types of acute myeloid leukemia (AML) cells with different genetic mutations, representing a therapeutic opportunity with broad application. Yet how JMJD1C regulates the leukemic programs of various AML cells is largely unexplored. Here we show that JMJD1C interacts with the master hematopoietic transcription factor RUNX1, which thereby recruits JMJD1C to the genome to facilitate a RUNX1-driven transcriptional program that supports leukemic cell survival. The underlying mechanism hinges on the long N-terminal disordered region of JMJD1C, which harbors two inseparable abilities: condensate formation and direct interaction with RUNX1. This dual capability of JMJD1C may influence enhancer-promoter contacts crucial for the expression of key leukemic genes regulated by RUNX1. Our findings demonstrate a previously unappreciated role for the non-catalytic function of JMJD1C in transcriptional regulation, underlying a mechanism shared by different types of leukemias.

Objective:To investigate the changes in brain functional network and structural-functional network coupling in children with drug-resistant epilepsy (DRE), and to analyze their correlation with cognitive function, disease duration, and age of onset.Methods:This study was a cross-sectional study. Clinical and imaging data of 19 children with DRE who received consultation and treatment at the Affiliated Hospital of Zunyi Medical University from August 2021 to August 2023 (DRE group) were prospectively included. Another 27 age-and sex-matched healthy children were collected as the healthy control group. All subjects had 3D-T 1WI, T 2 fluid-attenuated inversion recovery, diffusion tensor imaging (DTI), resting-state functional magnetic resonance imaging (rs-fMRI) scans and Wechsler Intelligence Scale assessments. Independent sample t-test and Mann-Whitney U test were used to analyze the global and local topological attributes, as well as the structural-functional coupling (SFC) values at the whole brain and modular levels in two groups. Correlations between abnormal resting state brain functional network indicators and the Wechsler Intelligence Scale score [verbal comprehension index (VCI), perceptual reasoning index (PRI), working memory index (WMI), processing speed index (PSI), full scale intelligence quotient (FSIQ)], disease duration and age of onset was evaluated using a Spearman or Pearson correlation analysis. Results:Compared to the healthy control group, DRE group exhibited decreased VCI, PRI, WMI, PSI, FSIQ and the differences were all statistically significant (all P<0.05). Both brain functional networks had small world attributes. There was a statistically significant difference in the area under the curve of sparsity of degree centrality (DC) in the left pallidum between the DRE group and healthy control group (2.998±0.942, 4.992±1.945, t=-4.07, FDR corrected P<0.05). Compared with the control group, the DRE group had decreased SFC within the limbic network (LN) ( P<0.05), increased SFC within the sensorimotor (SMN) ( P<0.05), decreased SFC between the default mode network-LN ( P<0.05), and increased SFC between the SMN-attentional network (AN) ( P<0.05). There was no statistically significant difference in SFC at the whole brain level between the two groups. Correlation analysis indicated that DC in left pallidum in DRE group negatively correlated with the PSI ( r=-0.537, P=0.018), and SFC between the SMN and AN demonstrated a negative correlation with age of onset ( r=-0.537, P=0.018). Conclusion:The altered DC in left pallidum may be related to cognitive impairment in children with DRE, providing biomarker information for the study of neural mechanisms in children with DRE.

Objective:To report the nationwide surveillance results of pathogenic profiles and antimicrobial resistance patterns of Gram-positive bloodstream infections in China in 2023.Methods:The clinical isolates of Gram-posttive bacteria from blood cultures were collected in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System（BRICS）during January to December 2023. Antimicrobial susceptibility testing was performed using the dilution method recommended by the Clinical and Laboratory Standards Institute（CLSI）. Statistical analyses were conducted using WHONET 5.6 and SPSS 25.0 software.Results:A total of 4 385 Gram-positive bacterial isolates were obtained from 60 participating center. The top five pathogens were Staphylococcus aureus（ n=1 544，35.2%），coagulase-negative Staphylococci（ n=1 441，32.9%）， Enterococcus faecium（ n=574，13.1%）， Enterococcus faecalis（ n=385，8.8%），and α-hemolytic Streptococci（ n=187，4.3%）. The prevalence of methicillin-resistant Staphylococcus aureus（MRSA）and methicillin-resistant coagulase-negative Staphylococci（MRCNS）was 26.2%（405/1 544）and 69.8%（1 006/1 441），respectively. Notably，all Staphylococci remained susceptible to glycopeptide or daptomycin. Staphylococcus aureus demonstrated excellent susceptibility（>97.0%）to cephalobiol，rifampicin，trimethoprim-sulfamethoxazole，linezolid，minocycline，tigecycline，and eravacycline. No Enterococcus exhibiting resistance to linezolid were detected. Glycopeptide resistance was uncommon but more frequent in Enterococcus faecium（resistance to vancomycin and teicoplanin：both 1.7%）compared to Enterococcus faecalis（both 0.3%）. The detection rates of MRSA and MRCNS exhibited significant regional variations across the country（ χ2=17.674 and 148.650，respectively，both P<0.001）. No vancomycin-resistant Enterococci were detected in central China. Institutional comparison demonstrated higher prevalence of MRSA（ χ2=14.111， P<0.001）and MRCNS（ χ2=4.828， P=0.028）in provincial hospitals than that in municipal hospitals. Socioeconomic analysis identified elevated detection rates of both MRSA（ χ2=18.986， P<0.001）and MRCNS（ χ2=4.477， P=0.034）in less developed regions（per capita GDP
