With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

Histone lactylation is a recently identified post-translational modification, wherein lactate mediates the enzymatic addition of lactyl groups to lysine residues on histones. Since its discovery, extensive research has demonstrated that histone lactylation is widely present in human tissues and plays a pivotal role in regulating the transcription of specific genes. Subsequent studies have further established this modification as a widespread epigenetic mark with significant physiological implications. With advancing research, accumulating evidence confirms that lactylation at distinct histone sites elicits diverse biological effects—such as promoting cell proliferation, driving inflammatory responses, and enhancing fibrosis—all of which profoundly influence disease progression and serve as key drivers of disease onset and development. Conversely, inhibiting histone lactylation can alter disease outcomes, positioning histone lactylation as a promising therapeutic target. Moreover, studies have revealed crosstalk between histone lactylation and other post-translational modifications, such as acetylation and methylation, which collectively regulate disease progression. Notably, lactylation occurs not only on histones but also on non-histone proteins. Histone lactylation activates specific gene transcription and reshapes metabolic epigenetics, while non-histone lactylation directly modulates enzyme activity, signal transduction, and protein stability. These two facets form a synergistic network through shared lactate pools, common modifying enzyme systems, and pathway crosstalk, thereby constructing a multi-dimensional regulatory framework—namely, the “histone lactylation-metabolism hub-non-histone lactylation” axis. This architecture bridges metabolism and epigenetics, and deciphering its topological structure may provide novel targets for precise intervention in diseases driven by lactate-mediated signaling hijacking. Traditional Chinese medicine (TCM), grounded in clinical practice, has been shown to regulate histone lactylation by modulating lactate metabolism and lactylation-related enzymes, thereby influencing disease progression. Moreover, certain TCM formulations exhibit potential as alternative therapies for drug-resistant diseases, underscoring the significance of further exploring TCM-mediated regulation of histone lactylation in future therapeutic strategies. This review aims to elucidate the mechanisms underlying histone lactylation, systematically delineate the associations between site-specific histone lactylation and various diseases, present a comprehensive landscape of the “lactate-histone lactylation and functional protein lactylation” axis, and summarize the mechanistic basis and research advances in TCM-mediated regulation of histone lactylation for disease treatment. Additionally, we discuss current challenges in histone lactylation research and propose future directions, ultimately aiming to deepen understanding and broaden perspectives on the roles and therapeutic potential of histone lactylation in disease.

ObjectiveTo evaluate the efficacy and safety of Janus kinase (JAK) inhibitors combined with Chinese herbal medicine (CHM) in treating rheumatoid arthritis (RA). MethodsClinical data from 169 RA patients were retrospectively collected. Among them, 71 cases received JAK inhibitors as the control group, while 98 cases received JAK inhibitors plus CHM as the observation group, both treated for 24 weeks. The rheumatoid factor (RF), cyclic citic peptide antibody (anti-CCP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and white blood cell count (WBC) were recorded before and after treatment. Databases including CNKI, Wanfang, VIP, PubMed and Web of Science were searched from inception till August 31st, 2025 for randomized controlled trials (RCTs) on the combined use of JAK inhibitors and CHM for RA. The methodological quality of the included studies was evaluated using the risk of bias assessment tool. Meta-analyses were performed for RF, anti-CCP, ESR, CRP, 28-joint disease activity score (DAS28), overall clinical effective rate, and incidence of adverse events. Sensitivity analysis were also performed. ResultsThe retrospective study demonstrated that after treatment, ESR, CRP, and anti-CCP levels decreased in the observation group, while ESR and CRP levels decreased in the control group (P<0.05). Moreover, ESR and RF levels in the observation group were lower than those in the control group (P<0.05). A total of 9 RCTs involving 770 patients were included in the meta-analysis. The results indicated that the JAK inhibitors plus CHM group was superior to the JAK inhibitors group in reducing RF (MD=-8.97, 95%CI -15.01 to -2.94, P=0.004), CRP (MD=-3.34, 95%CI -3.82 to -2.86, P<0.001), ESR (MD=-5.33, 95%CI -7.98 to -2.69, P<0.001), and DAS28 score (MD=-0.54, 95%CI -0.74 to -0.34, P<0.001), as well as in improving the overall clinical effective rate (OR=4.53, 95%CI 2.55 to 8.03, P<0.001). No statistically significant differences were observed between groups in anti-CCP levels (SMD=-2.08, 95%CI -4.41 to 0.24, P=0.080) or incidence of adverse events (OR=0.93, 95%CI 0.55 to 1.57, P=0.790). ConclusionThe combination of JAK inhibitors and CHM demonstrates remarkable efficacy in treating RA, contributing to improved disease activity and reduced inflammatory markers with a favorable safety profile.

Objective: To develop a RHCE genotyping assay based on kompetitive allele-specific PCR (KASP) and assess its clinical accuracy for RhCE blood group determination. Methods: KASP primers were designed to interrogate three RHCE loci: the 109 bp insertion/deletion in intron 2, c. 307T>C, and c. 676C>G. A total of 1 194 RhD-positive inpatients from Chengdu were typed by both KASP genotyping and manual tube serology. Discordant samples (n=10) were retested by both methods and further resolved by Sanger sequencing. An additional 377 cases were tested for the c. 48C>G locus to evaluate the predictive accuracy of individual loci and combined locus testing for RhC antigen. Results: Genotyping concordance with serology was 100.0% for both the c. 676C>G locus (RhE/Rhe) and the c. 307T>C locus (Rhc). For RhC prediction using the 109 bp insertion, overall accuracy was 99.7% (1 191/1 194); the 3 discordant cases were confirmed by Sanger sequencing to be false negatives attributable to 109 bp deletion in intron 2. Testing the c. 48C>G allele for RhC prediction yielded 7 false positives, with an accuracy of 98.1% (370/377). RhC antigen status was determined by combining the 109 bp insertion and the c. 48C allele. After excluding 10 samples with inconsistent results between the two loci, the accuracy reached 100% in the remaining 367 samples. When both loci were applied in combination, accuracy reached 100% in the 367 cases with concordant results. Among the 1 194 patients, CCee (45.8%) and CcEe (31.7%) were the most common RhCE phenotypes. The e antigen had the highest positivity rate (92.2%), and the Ce haplotype was the most frequent (66.9%). Conclusion: The KASP-based RHCE genotyping method achieves high accuracy for clinical RhCE typing. Combining the 109 bp insertion/deletion with the c. 48C allele significantly improves RhC antigen prediction compared with either locus alone. This method was applied to RhCE genotyping of 1 194 RhD-positive inpatients in Chengdu, providing local RhCE phenotype and haplotype distribution data to support RhCE-matched transfusion practice.

Objective:
This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH).
Methods:
A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups.
Results:
The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05).
Conclusion
This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

Diminished ovarian reserve (DOR) is a decrease in the number of available follicles in the ovaries and the quality of oocytes, which in turn affects follicle development, ovulation and sex hormone secretion, resulting in decreased fertility. Harmful chemical components in cigarette smoke, such as nicotine and benzopyrene, can interfere with the hypothalamic-pituitary-ovarian axis and impair ovarian reserve and function through apoptosis, autophagy, oxidative stress and DNA damage, which can directly affect ovarian granulosa cells and oocytes, causing oocyte development disorders, increased apoptosis of granulosa cells, destroy reproductive endocrine homeostasis, lead to DOR and affect female fertility. At present, the molecular mechanism of premature ovarian dysfunction caused by cigarette smoke is not fully understood. In this paper, the molecular mechanism of cigarette smoke exposure affecting ovarian tissue and mediating ovarian function was reviewed, aiming to provide theoretical reference for the study of cigarette smoke induced DOR and affecting ovarian function, and to provide pregnant guidance for infertile women in bad environment and bad living habits.

Objective To explore the association between cardiorespiratory fitness and total atherosclerotic burden of brain-and heart-arteries in patients with ischemic stroke.Methods This study retrospectively enrolled consecutive patients with ischemic stroke of the large-artery atherosclerosis or small-artery occlusion subtypes accompanied by cervicocephalic atherosclerosis,who were admitted to the Department of Neurology,Xuanwu Hospital,Capital Medical University,between May 2023 and December 2024.General and clinical data,including age(<60years,≥60years),sex,admission blood pressure,body mass index,history of hypertension,diabetes mellitus,hyperlipidemia,ischemic stroke,symptomatic coronary artery disease,smoking,alcohol consumption,and medication use(including antiplatelet drugs,anticoagulants,lipid-lowering drugs,antidiabetic drugs,antihypertensive drugs,and β-blockers),characteristics of ischemic stroke(including the duration of onset,ischemic side[left,right,bilateral],and ischemic location[anterior circulation,posterior circulation,bilateral circulation])were collected from all patients enrolled.On the morning after admission,fasting venous blood samples were collected to measure the levels of triglycerides,total cholesterol,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,fasting blood glucose,glycated hemoglobin,homocysteine,fibrinogen,D-dimer,C-reactive protein,high-sensitivity C-reactive protein,N-terminal pro-B-type natriuretic peptide,creatine kinase-MB,cardiac troponin T,and myoglobin.Transthoracic echocardiography was performed within 7 days after admission to evaluate cardiac function.Left ventricular ejection fraction and cardiac output were recorded,and cardiac index were calculated.Upon admission,neurological impairment,disability,motor function,and balance ability were assessed using the National Institutes of Health stroke scale(NIHSS),modified Rankin scale(mRS),Fugl-Meyer assessment(FMA),and Berg balance scale,respectively.The Saltin-Grimby physical activity level scale was used to evaluate the intensity of habitual physical activity prior to stroke onset.Cardiopulmonary exercise testing was performed within 7 days after admission to assess cardiopulmonary fitness.During the test,peak oxygen uptake(VO2peak),percentage of predicted VO2peak(VO2peak%pred),and metabolic equivalent of task(MET)were recorded.Based on the minimum oxygen uptake required for independent living(15 ml/[kg·min]),VO2peak was classified into low VO2peak(<15 ml/[kg·min])and high VO2peak(≥15 ml/[kg·min]).With VO2peak%pred<0.60 as the cutoff,VO2peak%pred was divided into low VO2peak%pred(<0.60)and high VO2peak%pred(≥0.60).MET were categorized into low MET(<mean MET)and high MET(≥mean MET)according to the mean value of MET in this study population.Imaging data of cardio-cerebral arteries were obtained by simultaneous CT arteriography within 7 days after admission.Total atherosclerotic burden of brain-and heart-supplying arteries(TAB-BHAs)was used to quantitatively evaluate the overall degree of cardio-cerebral atherosclerosis.And patients were stratified into high TAB-BHAs(≥4 points)and low TAB-BHAs(<4 points)groups.The differences in general and clinical characteristics,as well as cardiopulmonary fitness indices,were assessed among different groups of TAB-BHAs.Spearman' s correlation was used in the preliminary analysis of the relationship between cardiorespiratory fitness indicators and TAB-BHAs.Multivariate Logistic regression was conducted with VO2peak,low VO2peak%pred,and low METs as independent variables,and high TAB-BHAs as the dependent variable to assess the association between cardiopulmonary fitness and TAB-BHAs.Covariates were selected through regressions stratified by age≥60 years,male,the least absolute shrinkage and selection operator(LASSO),and the variables exhibit statistically significant differences between the low and high TAB-BHAs groups,respectively.Results A total of 104 patients with ischemic stroke were enrolled.Among all patients enrolled,60patients(with ages ranging from 30 to 72years and a mean age of[54±11]years)met the inclusion and exclusion criteria,and were ultimately included.Amid the 60 patients,52 were male and 8 were female.There were 20 patients(33.3%)with low VO2peak,28 patients(46.7%)with low VO2peak%pred,and 31 patients(51.7%)with low MET(MET<5.0).45 patients were classified into the low TAB-BHAs group and 15 into the high TAB-BHAs group.(1)Compared with the low TAB-BHAs group,patients in the high TAB-BHAs group were significantly older and had a higher proportion of patients aged≥60 years,they also showed significantly higher fibrinogen levels and a history of antihypertensive drug use(all P<0.05).No significant differences were observed in other general or clinical characteristics between the two groups(all P>0.05).Regarding cardiopulmonary fitness parameters,patients in the high TAB-BHAs group had lower VO2peak and MET levels,and higher proportions of patients with low VO2peak,low VO2peak%pred,and low MET compared with those in the low TAB-BHAs group(all P<0.05).(2)Based on the Spearman's correlation analysis,VO2peak(r=-0.298,P=0.021),VO2peak%pred(r=-0.305,P=0.018),MET(r=-0.303,P=0.018)all exhibited negative correlations between and TAB-BHAs.(3)LASSO regression was used to identify the most pertinent variables for high TAB-BHAs,including low VO2peak,low VO2peak%pred,and fibrinogen.Multivariate Logistic regression analysis was then performed with low VO2peak,low VO2peak%pred,and low MET as independent variables and high TAB-BHAs as the dependent variable.The results showed that after adjusting for age≥60 years,male,and fibrinogen,both low VO2peak(adjusted OR,4.420,95%CI 1.052-18.573,P=0.042)and low VO2peak%pred(adjusted OR,7.423,95%CI 1.411-39.046,P=0.018)were independently associated with high TAB-BHAs in ischemic stroke patients.After further adjusting for variables that differed among high and low TAB-BHAs groups(including age≥60 years,male,fibrinogen,and history of using antihypertensive drugs),multivariate Logistic regression showed that low VO2peak%pred remained independently associated with high TAB-BHAs in ischemic stroke patients(adjusted OR,6.347,95%CI 1.170-34.418,P=0.032).Conclusion Poor cardiopulmonary fitness might be associated with high degree of overall cardio-cerebral atherosclerosis,suggesting cardiorespiratory fitness as a potential correlated indicator that could provide clues for improving early screening of patients with heavy cardio-cerebral atherosclerotic burden and for exploring the underlying mechanisms.
