BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To analyze the clinical characteristics of the Chikungunya fever outbreak in Shunde District, Foshan City, Guangdong Province in July 2025 and the risk factors associated with delayed viral RNA clearance.Methods:A total of 562 patients with Chikungunya fever admitted to three designated hospitals in Shunde District from July 10 to 30, 2025 were enrolled. Demographic data, clinical manifestations, and laboratory findings were collected. Patients were categorized into four age groups including minors (<18 years), young adults (18 to 39 years), middle-aged adults (40 to 64 years) and elderly adults (≥65 years). The differences of clinical characteristics among these age groups were analyzed. Intergroup comparisons were performed using chi-square test, one-way analysis of variance, or Kruskal-Wallis H test. Pairwise comparisons between groups were conducted using the Bonferroni or Games-Howell or Dunn method. Binary logistic regression was employed to analyze risk factors associated with delayed viral RNA clearance (>7 days). Results:The mean age of the 562 enrolled Chikungunya fever patients was (44.8±21.3) years. Fever, arthralgia and rash were the three core symptoms, with incidence rates of 87.5% (492/562), 88.4%(497/562) and 69.6%(391/562), respectively. At discharge, only 54.1%(304/562) of patients achieved complete symptom resolution, while 26.5%(149/562) still had arthralgia and 36.1%(203/562) had residual rash. Significant differences were observed among age groups in the incidence of fever ( χ2=9.43, P=0.024), peak body temperature ( F=6.54, P<0.001), incidence of arthralgia ( χ2=26.89, P<0.001), duration of arthralgia ( F=12.68, P=0.001), incidence of rash ( χ2=68.99, P<0.001), rate of residual rash at discharge ( χ2=32.37, P<0.001), lymphocyte count ( F=12.94, P<0.001), platelet count ( F=14.95, P<0.001), and C-reactive protein levels (CRP) ( H=94.18, P<0.001). Further pairwise comparisons revealed that compared to the middle-aged and elderly groups, the minor group had a higher incidence of fever and a lower incidence of arthralgia, and the duration of arthralgia was shorter than the elderly group (all P<0.008 3). Compared with the other three groups, the elderly group had lower incidence and residual rate of rash, and lower platelet counts (all P<0.008 3), and higher levels of CRP (all P<0.05). The elderly group had lower lymphocyte counts compared to the minor and young adult groups (both P<0.05). Significant differences were found among age groups in the time to viral RNA clearance ( F=5.77, P=0.003) and length of hospital stay ( F=11.64, P<0.001), with the elderly group having significantly longer duration for both compared to the other three groups (all P<0.05). Multivariate analysis showed that advanced age (odds ratio ( OR)=1.049, 95% confidence interval ( CI) 1.015 to 1.083), longer duration of fever ( OR=1.529, 95% CI 1.086 to 2.155) and longer duration of arthralgia ( OR=1.927, 95% CI 1.318 to 2.817) were independent risk factors for delayed viral RNA clearance (all P<0.05). Conclusions:Patients with Chikungunya fever in Shunde District primarily present with fever, arthralgia and rash. The incidence and characteristics of these three core symptoms show age-related variations. Elderly patients and those with longer durations of fever or arthralgia are more likely to experience delayed viral clearance.

Precise management of the activity dose is a core component of the(early mobilization,EM)plan for ICU patients.However,the lack of clinical practice guidelines related to EM dose of existing programs hinders the implementation and development of EM in ICU patients to some extent.Therefore,this review focuses on 4 aspects,covering the definition of activity dose,assessment tools,the current clinical implementation status,and implications for future nursing.The aim is to systematically review the assessment tools and intervention strategies for the activity dose of EM in ICU patients,providing a reference for optimization of EM programs.

Objective To investigate the predictive value of serum lipoprotein-associated phospholipase A2(Lp-PLA2)and homocysteine(Hcy)combined with white matter hyperintensities(WMH)for cognitive impairment in patients with cerebral small vessel disease(CSVD).Methods A total of 240 patients with CSVD were selected.According to the Montreal Cognitive Assessment(MoCA)scale,all subjects were divided into the non-cognitive impairment group(MoCA≥26 points,120 cases)and the cognitive impairment group(MoCA＜26 points,120 cases).Paraventricular white matter high signal(PWMHs)and deep white matter high signal(DWMHs)were scored by Fazekas scale.The sum of the two parts was the total score,and the severity of DWMHs was graded by the score.The basic information,serum Lp-PLA2,Hcy level and severity of WMH were compared between the two groups.Logistic regression was applied to analyze influencing factors of cognitive impairment in CSVD patients.The predictive value of serum level of Lp-PLA2 and Hcy and WMH for cognitive impairment in CSVD patients was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the non-cognitive impairment group,patients of the cognitive impairment group were older,had higher serum levels of Lp-PLA2 and Hcy,and had more severe of WMH(P＜0.05).Results of Logistic regression analysis showed that serum Lp-PLA2,Hcy levels and severity of WMH were influencing factors for cognitive impairment of patients with CSVD(P＜0.05).The results of ROC curve analysis showed that the area under the curve of serum Lp-PLA2,Hcy level combined with severity of WMH predicting cognitive impairment in patents with CSVD was 0.812,the sensitivity was 81.7%and the specificity was 71.7%(P＜0.05).Conclusion Patients with cognitive impairment caused by CSVD have higher serum levels of Lp-PLA2 and Hcy,and more severe WMH.The combination of the three has a relatively high predictive value for cognitive impairment in patents with CSVD.

Objective To compare functional differences of CD8+T cells in lung tissues between young and aged C57BL/6J mice during the contraction phase and memory immune response phase after infection with influenza A(H1N1)virus.Methods Lung tissues from young(3-month-old)and aged(24-month-old)C57BL/6J female mice without influenza virus infection were collected to prepare single-cell suspensions,which were stimulated with phorbol 12-myristate 13-acetate(PMA)/ionomycin or cluster of differentiation(CD)3/CD28 antibodies(T-cell antigen receptor/co-stimulatory signals)respectively(non-specific antigens stimulation).Flow cytometry intracellular cytokine staining(ICS)was performed on lung CD8+T cells to detect their secretion capacity of tumor necrosis factor-α(TNF-α)and interferon-γ(IFN-γ).Young and aged C57BL/6J mice were infected intranasally with 490 PFU PR8 influenza virus,and reinfected with homologous influenza virus 28 days later.Lung tissues were isolated on day 28(the contraction phase)and day 32(the memory immune response phase)after primary infection.Influenza virus-specific MHC-Ⅰ tetramer staining was used to detect the proportion of virus-specific CD8+T cells in lung tissue CD8+T cells,and ICS was used to analyze TNF-α,IFN-γ,and granzyme B expression in CD8+CD44high T cell subset.Results After non-specific antigen stimulation,TNF-α and IFN-γ secretion capacity in lung tissue CD8+T cells of aged group mice was significantly higher than that of young group(P＜0.05).After virus-specific antigen stimulation,there were no statistically significant differences in the proportion of virus-specific CD8+T cells and the expression levels of TNF-α,IFN-γ,and granzyme B between the two groups of mice during the contraction phase(P＞0.05),while during the memory immune response phase,the proportion of virus-specific CD8+T cells and the expression levels of TNF-α,IFN-γ,and granzyme B in the aged group mice were significantly lower than those in the young group(P＜0.05).Conclusion CD8+T cells in aged mice maintain normal immune-related factor expression function under non-specific antigen stimulation,but show impaired immune-related factor expression function during antigen-specific memory immune response phase,suggesting that aging leads to defects in the formation or maintenance of CD8+T cell immune memory.

Objective We aimed to evaluate the efficacy and safety of Shengxuebao Mixture in the treatment of cancer-related anemia(CRA)presenting with syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood.Methods A randomized,double-blind,placebo-controlled,multicenter clinical trial was conducted.Eligible patients with malignant tumors meeting the inclusion and exclusion criteria were enrolled from 26 hospitals,including Dongzhimen Hospital,Beijing University of Chinese Medicine,Xiaogan Central Hospital,and Yangzhou Hospital of Traditional Chinese Medicine,from June 1,2022,to September 30,2024.Patients were allocated 1:1 to either the experimental group receiving Shengxuebao Mixture or the control group receiving its simulator(placebo)using a block randomization method under double-blind conditions.Both groups received 15 mL orally three times daily for 28 consecutive days.The primary efficacy indicators included the hemoglobin(Hb)improvement rate(RHb)and the traditional Chinese medicine(TCM)syndrome improvement rate(RTCM)at week 4 of treatment.The secondary efficacy indicators encompassed Hb and red blood cell(RBC)count,Karnofsky Performance Status(KPS)score,TCM syndrome score,individual TCM symptom scores,and changes in each of these indicators compared to the baseline period at weeks 2,4,and 6 of treatment.Safety evaluations were conducted at week 4 of treatment.Results A total of 239 patients were enrolled,with 225 cases included in the Full Analysis Set(FAS)(109 in the experimental group vs.116 control group),163 in the Per Protocol Set(PPS)(77 vs.86),and 225 in the Safety Set(SS)(109 vs.116).Baseline characteristics between groups showed no significant differences.Significant differences were observed between the experimental and control groups in RHb at week 4(FAS:49.51%vs.35.24%,P<0.05;PPS:53.25%vs.36.05%,P<0.05)and RTCM at week 4(FAS:61.54%vs.39.62%,P<0.01;PPS:64.94%vs.40.70%,P<0.01).At weeks 2,4,and 6,the experimental group showed greater improvements in Hb and RBC counts than the control group.Additionally,the TCM syndrome scores were lower in the experimental group than in the control group at these time points.Except for week 2 in PPS,the KPS improvement was better in the experimental group than in the control group(P<0.05).The experimental group also demonstrated a greater reduction in scores for individual TCM symptoms such as spiritlessness and weakness,poor appetite and reduced food intake at weeks 4 and 6 compared to the control group(P<0.05,P<0.01).Furthermore,the reduction in vertigo score was more pronounced in the experimental group at week 6(P<0.01).For the score of pale and lusterless complexion,only in the PPS was the reduction from baseline more significant in the experimental group than in the control group at weeks 4 and 6(P<0.05).No significant differences were observed between the experimental and control groups in the incidence of all adverse events or drug-related adverse reactions.Conclusion Shengxuebao Mixture demonstrates significant efficacy in patients with CRA presenting syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood,effectively increasing Hb levels,ameliorating TCM syndromes,alleviating clinical symptoms,and enhancing functional status,with no significant difference in adverse drug reactions compared to the placebo.
