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 investigate the frequency and related factors of ineffective triggering (IT) and double triggering (DT) in patients with acute brain injury undergoing invasive mechanical ventilation. METHODS: A retrospective cohort study was conducted using data from a single-center observational trial. Patients with acute brain injury [traumatic brain injury, stroke, and post-craniotomy for brain tumors] undergoing mechanical ventilation in the intensive care unit (ICU) of Beijing Tiantan Hospital, Capital Medical University between June 2017 and July 2019 were retrospectively analyzed. Demographic and clinical data were collected. Respiratory parameters and waveforms during the first 3 days of mechanical ventilation were recorded, with 15-minute waveform segments collected 4 times daily. Airway occlusion pressure (P_0.1) was measured via end-expiratory hold at the end of each recording. IT and DT were identified based on airway pressure, flow, and esophageal pressure waveforms, and the ineffective triggering index (ITI) and DT incidence were calculated. Multivariate Logistic regression was used to identify factors associated with IT and DT. RESULTS: A total of 94 patients with acute brain injury were ultimately enrolled, including 19 cases of traumatic brain injury (20.2%), 39 cases of stroke (41.5%), and 36 cases of post-craniotomy for brain tumor (38.3%). Supratentorial injury was observed in 49 patients (52.1%), while infratentorial injury was identified in 45 patients (47.9%). A total of 94 patients with 1 018 datasets were analyzed; 684 (67.2%) datasets were on pressure support ventilation (PSV), and 334 (32.8%) were on mandatory ventilation. IT was detected in 810 (79.6%) datasets, with a median incidence of 2.1% (0.3%, 12.0%). Datasets demonstrating IT were characterized by lower P_0.1, higher tidal volume (VT), reduced respiratory rate (RR), and decreased minute ventilation (MV) compared to those without IT. The proportion of datasets exhibiting IT was higher during PSV than in mandatory ventilation [83.8% (573/684) vs. 71.0% (237/334), P < 0.05], while, the prevalence of ITI ≥ 10% was lower [23.8% (163/684) vs. 33.5% (112/334), P < 0.05]. DT was detected in 305 datasets (30%), with a median incidence of 0.6% (0.4%, 1.3%). Datasets exhibiting DT were characterized by higher VT, reduced RR, and lower pressure support levels. The incidence of DT was lower in PSV compared to mandatory ventilation modes [0% (0%, 0.3%) vs. 0% (0%, 0.5%), P < 0.05]. The post-craniotomy for brain tumors group exhibited higher ITI, lower RR, reduced MV, and a greater proportion of infratentorial lesions, compared to the TBI group. The infratentorial lesion group demonstrated higher ITI and incidence of DT compared to the supratentorial lesion group [ITI: 3.1% (0.7%, 17.8%) vs. 1.5% (0%, 8.3%), incidence of DT: 0% (0%, 0.5%) vs. 0% (0%, 0%), both P < 0.05]. After adjusting for confounding factors through multivariate logistic regression analysis, infratentorial lesion [odds ratio (OR) = 2.029, 95% confidence interval (95%CI) was 1.465-2.811, P < 0.001], lower P_0.1 (OR = 0.714, 95%CI was 0.616-0.827, P < 0.001), and mandatory ventilation (OR = 1.613, 95%CI was 1.164-2.236, P = 0.004) were independently associated with IT. Additionally, infratentorial lesion (OR = 1.618, 95%CI was 1.213-2.157, P = 0.001), large tidal volume (OR = 1.222, 95%CI was 1.137-1.314, P < 0.001), lower pressure support levels (OR = 0.876, 95%CI was 0.829-0.925, P < 0.001), and mandatory ventilation (OR = 2.750, 95%CI was 1.983-3.814, P < 0.001) were independently associated with DT. CONCLUSION IT and DT were common in patients with acute brain injury. Infratentorial lesions and mandatory ventilation were independently associated with both IT and DT.

Objective To explore the facilitators and barriers of palliative care volunteering,and to provide references for further advancement of palliative care volunteering.Methods Purposeful sampling was used to select 12 volunteers from a palliative care ward in Hangzhou,Zhejiang Province,between April and September 2024.Semi-structured interviews were conducted,and directed content analysis was applied to organize and analyze the data,followed by theme analysis.Results Facilitators and barriers for volunteers' participation in palliative care volunteering were extracted.The 5 sub-themes of facilitators include motivating factors and perceived benefits,support and collaboration among volunteers,professional training and healthcare recognition,increased social awareness and public acceptance,and government support and institutional safeguards.The 5 sub-themes of barriers include limitations in individual capacity,challenges in collaboration with patients,families and healthcare workers,inadequate management and service mechanisms,uneven development of palliative care and insufficient public attention to psychological problems,and inadequate relevant laws and incentives.Conclusion There are more factors affecting the development of palliative care volunteering,and healthcare professionals should adopt targeted strategies to promote the active participation of volunteers in order to promote the sustainable development of palliative care volunteering.

Objective:To observe the efficacy of transcutaneous electrical acupoint stimulation (TEAS) when it is combined with warm moxibustion scraping therapy (WMST) in the treatment of myofascial pain syndrome (MPS) in the lumbodorsal region.Methods:A total of 112 patients with lumbodorsal MPS were randomly divided into a control group and a combination group, each of 56. All of the patients received TEAS, but those in the combined group additionally received warm moxibustion scraping therapy. The treatment consisted of 3 consecutive courses, with each course lasting 2 weeks and a 1-day rest interval between courses. Before the treatment and after completing 3 courses (post-treatment), the therapeutic effects were evaluated using traditional Chinese medicine (TCM) syndrome scores, visual analogue scale (VAS) ratings for pain, a pain rating index (PRI), present pain intensity (PPI), the Oswestry Disability Index (ODI), and the Pittsburgh Sleep Quality Index (PSQI).Results:After the treatment, significant decreases were observed in the average TCM syndrome, VAS pain, PRI, PPI, ODI and PSQI scores of both groups, but the combination group′s averages were all significantly lower than those of the control group. Efficacy among the combination group (92.9%) was significantly higher than among the controls (62.5%).Conclusions:Supplementing TEAS with warm moxibustion scraping can more effectively relieve lumbodorsal pain and dysfunction among patients with lumbodorsal MPS, and improve their sleep quality.

Objective To provide relevant suggestions for ethical considerations in clinical research by searching literature related to ethics in clinical research using the visualization analysis software CiteSpace,and to analyze and compare the current research status of clinical research ethics at home and abroad.Methods The papers on the application of medical ethics in clinical trials from the core collection of CNKI and Web of Science databases were collected and the bibliometric software CiteSpace was used to draw a knowledge map of domestic and foreign literature.The research hotspots and development trends of medical ethics in clinical trials were analyzed.Results In terms of the process of informed consent,risk minimization,fair selection,and protection on the rights and interests of vulnerable groups,the focus of medical ethics research in China were basically consistent with foreign literature.The difference was that foreign research focused more on ethical education,the quality of life of research participants,and ethical counseling.Otherwise,domestic research focused more on the quality management of clinical trials and the specificity of traditional Chinese medicine research,with research on vulnerable groups mostly focused on children.Conclusion Chinese researchers should strengthen multi-dimensional research on medical ethics in China,and gradually expand their view from ethical review points and management research to applied research solved clinical problems and the specificity of research participants,and increasing the number and dimensions of research.

Objective To study the expression of PLA2G2A and its significance in vaginal wall tissue of patients with pelvic organ pro-lapse(POP).Methods Twenty-three patients without POP(control group)and 26 patients with POP(POP group)admitted to the Third Affiliated Hospital of Zhengzhou University,between June 2023 and September 2024,were selected.Histological features were observed using hematoxylin and eosin and Masson's trichrome staining.Localization of PLA2G2A was detected using immunofluorescence.The PLA2G2A expression level was assessed using immunohistochemistry,real-time PCR,and Western blotting.After transfecting fibroblasts with silenced PLA2G2A,changes in collagen Ⅰ and collagen Ⅲ were measured.Results The histological structure of the vaginal wall in the POP group was significantly different from that in the control group.PLA2G2A was expressed in fibroblasts,with protein and mRNA expression levels higher than those in the control group(P＜0.05).After silencing PLA2G2A,collagen Ⅰ and collagen Ⅲ expression were upregulated.Conclusion High expression of PLA2G2A in vaginal wall tissue of patients with POP.Increased PLA2G2A expression may be closely related to the development and presence of POP.

Objective To investigate the associations between physical health status,refraction and ocular biometrics in school-age children,and further clarify the relation of eyes'refractive status to physical growth and development,so as to provide scientific evidences for myopia prevention and con-trol.Methods A total of 1718 children(977 boys and 741 girls)aged 8-12 years were enrolled in this study.They were collected uncorrected visual acuity,refraction and ocular biometrics,including spherical equivalent,cylindrical equivalent,axial length(AL),corneal refraction(K1,K2)and anteri-or chamber depth(ACD),as well as the AL/CR ratio and spherical equivalent refraction(SER).Moreover,their height,weight and physical fitness level were measured,including speed,strength,flexibility,agility and aerobic endurance.Then all data were analyzed using the Pearson correlation,One-way ANOVA and multiple linear regression model.Results The overall prevalence of myopia was 43.83%,which was higher in girls than in boys(46.96%vs.41.45%).Moreover,the height and weight of school-age children were negatively correlated with SER(P<0.01),but positively correlated with AL,ACD and AL/CR(P<0.01).After controlling the age and gender variables in the multiple linear regression model,it was found that for 10-cm increase in height,SER decreased by 0.013 D(P<0.01),AL extended by 0.022 mm(P<0.01),and ACD increased by 0.002 mm(P<0.05).In addi-tion,for 10-kg increase in the body weight,the AL would be 0.009 mm longer(P<0.05)and ACD 0.002 mm deeper(P<0.05).Moreover,the speed,strength and agility were negatively correlated with SER(P<0.01,P<0.05),but positively correlated with AL,ACD and AL/CR(P<0.01,P<0.05).The maximal oxygen uptake level was positively correlated with SER(P<0.01),and negatively correlated with AL,ACD and AL/CR(P<0.01,P<0.05).After controlling the age and gender variables in the multiple linear regression model,it was found that the children with worse speed quality had shorter AL(-0.043 D,P<0.05).Meanwhile,the better agility was accompanied by the lower SER(-0.003 D,P<0.01),longer AL(+0.002 mm,P<0.05),lighter ACD(+4.812e-4 mm,P<0.05),and higher AL/CR(+2.446e-4,P<0.05).Conclusion With variables of age and gender controlled,the height,weight,and the speed and agility quality are highly associated with eyes'refractive status among chil-dren aged 8-12 years old.It is suggested that the human body may have a coordination mechanism to regulate the development of the body stature,physical fitness and ocular biometrics in the early child-hood,which should be considered in their myopia prevention and control.
