ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine （TCM） constitution and factors associated with hyperuricemia （HUA） in the HUA population， providing a reference for persona-lized prevention and management of HUA. MethodsA cross-sectional study was conducted among individuals who had completed both serum uric acid （SUA） testing and TCM constitution identification during health examinations. According to SUA levels， participants were divided into a hyperuricemia group and a normal SUA group； according to the constitution identification results， participants were classified into balanced constitution， single biased constitution， and mixed constitution. The distribution characteristics of TCM constitution were compared between the two groups； participants in the hyperuricemia group were stratified by sex and age （≥18 years and ＜40 years， ≥40 years）， and the distribution characteristics of TCM constitution were compared across different sex and age groups. Logistic regression was used to analyze factors associated with HUA， with further stratified analyses by sex and age. ResultsA total of 10 920 participants were included， comprising 4170 cases （38.19%） in the hyperuricemia group and 6750 cases （61.81%） in the normal serum uric acid group. According to TCM constitution， there were 420 cases （3.85%） with balanced constitution， 6108 cases （55.93%） with single biased constitution， and 4392 cases （40.22%） with mixed constitution. In the hyperuricemia group， there were 80 cases （19.05%） with balanced constitution； 2275 cases （37.25%） with single biased constitution， among which damp-heat constitution （1205 cases， 52.97%）， phlegm-dampness constitution （500 cases， 21.98%）， and qi-stagnation constitution （181 cases， 7.96%） accounted for relatively high proportions； and 1815 cases （41.33%） with mixed constitution， among which mixed constitution involving phlegm-dampness （51.35%， 932 cases）， mixed constitution involving blood stasis （47.00%， 853 cases）， and mixed constitution involving damp-heat （41.21%， 748 cases） accounted for relatively high proportions. Logistic regression showed that qi-stagnation constitution （OR=1.68）， mixed constitution involving qi-stagnation （OR=1.53）， mixed constitution involving phlegm-dampness （OR=1.55）， and mixed constitution involving blood stasis （OR=1.50） were independently associated with HUA （P＜0.05）. Sex-stratified analysis showed that mixed constitution involving phlegm-dampness was positively associated with HUA risk in females； age-stratified analysis showed that， among individuals aged ≥18 and ＜40 years， qi-stagnation constitution， mixed constitution involving qi stagnation， and mixed constitution involving phlegm-dampness were positively associated with HUA risk （all P＜0.05）. ConclusionThe prevalence of HUA differs markedly by sex and age. Mixed constitution accounts for a higher proportion of HUA patients. Qi-stagnation constitution， mixed constitution involving qi stagnation， mixed constitution involving phlegm-dampness， and mixed constitution involving blood stasis are associated with HUA. Notably， the specific association of mixed constitution involving phlegm-dampness in females and qi-stagnation constitution in young adults is particularly prominent.

The etiology of tumors is complex and influenced by multiple factors, including the host and environmental conditions. Allergy is primarily driven by the immune response of helper T cell 2 (Th2). Research has shown that the Th2 immune response is closely related to tumors, which is specifically manifested through Th2 antibodies, allergy-related effector cells and mediators within the tumors, as well as tumor immune-related functions. This internal interaction mechanism will increase the complexity and challenges associated with the clinical diagnosis and treatment of tumors and allergy. The formation of allergic constitution is shaped by both congenital and acquired factors, and its physical state is closely linked to the occurrence and progression of allergic diseases. Therefore, this paper aims to explore the relationship between tumors and allergic reactions from the perspective of traditional Chinese medicine (TCM) constitution theory. Based on the four basic principles of the TCM constitution, including endowment inheritance theory, environment constraint theory, body-spirit composition theory, and life process theory, this exploration will focus on four aspects: genetic factors and internal disease causes, inflammatory environments and functional regulation, psychological disorders and emotional pathogenesis, as well as age structure and disease risk. Furthermore, from the perspective of constitution-disease relation of chronic disease prevention, this paper will discuss the significant importance of adjusting allergic constitution to improve both subjective symptoms and objective indicators of allergic reactions in tumor patients.

Objective:To evaluate the safety and efficacy of secondary transport on extracorporeal membrane oxygenation (ECMO) for critically ill children.Methods:This was a retrospective cohort study. Data from 222 pediatric patients who underwent ECMO transport from May 2019 to May 2024 at 5 ECMO centers and Chinese Database of Pediatric Extracorporeal Life Support Organization were collected. The cases were divided into primary and secondary transport groups by nature of transport. The clinical data, including demographics, ECMO indications, transport distance, pre-transport lab results, prognosis and complications were analyzed. Two independent samples t-test, Wilcoxon test, and χ2 test or Fisher′s exact probability method were used to compare the differences between 2 groups and evaluate the safety and efficacy of secondary transport. Results:Among the 222 children transported with ECMO, there were 135 males and 87 females, with an age of 3.0 (0.2, 7.0) years. There were 202 cases in the primary transport group and 20 cases in the secondary transport group. All secondary transport patients had failed attempts at weaning ECMO before transfer. The patients in the secondary transport group were older, had higher rates of surgical cannulation, circulatory support, and pre-ECMO lactate levels compared to the primary transport group (7.0 (2.8, 10.0) vs. 3.0 (0.2, 6.0) years old, 55.0% (11/20) vs. 3.6% (7/202), 80.0% (16/20) vs. 41.6% (84/202), (10±4) vs. (7±6) mmol/L, Z=3.41, χ 2=66.31, 10.99, t=2.24, all P<0.05). In the secondary transport group, the vasoactive-inotropic scores of patients on circulatory support and the oxygenation index for patients requiring respiratory support were higher than those in the primary transport group (83±33 vs. 82±68, 51.0±1.8 vs. 37.4±10.2, t=2.36, 2.63, respectively; both P<0.05). There were no statistically significant differences between the 2 groups in sex, transport distance, pre-ECMO creatinine, arterial blood gas BE values, and ECMO duration (all P>0.05). No life-threatening complications occurred during the transport in either group. Two patients in the secondary transport group underwent heart transplantation, and 1 patient underwent radiofrequency ablation. The overall survival rate between the 2 groups showed no statistically significant difference (45.0% (9/20) vs. 55.4% (112/202), χ2=1.15, P>0.05). Conclusions:Secondary ECMO transport for critically ill children don't increase mortality or life-threatening complications during transport. ECMO patients who cannot receive effective treatment locally can benefit from secondary transport to an advanced ECMO center provides further treatment opportunities.

Objective To investigate whether the pyroptosis-related Toll-like receptor 4(TLR4)signaling pathway influences the malignant transformation of actinic keratosis(AK)into cutaneous squamous cell carcinoma(SCC).Methods A total of 6 lesion tissue samples each from patients with AK and SCC,as well as 5 normal skin tissue samples from healthy subjects as controls,were collected from the First Affiliated Hospital of Kunming Medical University between August 2020 and August 2021.Quantitative PCR(qPCR)and Western blot analysis were performed to determine the mRNA and protein expression levels of TLR4 pathway-related factors,including TLR4,CPB1,NLRP3,IL-1β,and IL-18.TLR4/TUNEL double immunofluorescence staining was used to evaluate TLR4 expression and the level of cellular pyroptosis in tissue samples.In addition,Western blotting was performed to analyze the expression differences of pyroptosis-related core proteins(pro-caspase-1,cleaved caspase-1/p20,GSDMD,and cleaved N-terminal GSDMD)and TLR4 among the normal keratinocyte cell line HaCaT and SCC cell lines A431 and SCL-1.Results Quantitative PCR and Western blot results showed that the mRNA and protein expression levels of TLR4,CPB1,NLRP3,IL-1β,and IL-18 were significantly higher in SCC tissues than in AK and normal skin tissues(P<0.05).TLR4/TUNEL double immunofluorescence results revealed a progressive increasing trend in TLR4 expression and pyroptosis levels from normal skin to AK and further to SCC(P<0.05).Furthermore,in SCL-1 cells,the expression levels of pro-caspase-1,cleaved caspase-1/p20,cleaved N-terminal GSDMD,and TLR4 were significantly upregulated(P<0.05),whereas in A431 cells,only TLR4 expression was increased(P<0.05),and the levels of other pyroptosis-related proteins were downregulated compared to HaCaT cells(P<0.05).Conclusion The expression of the TLR4 signaling pathway gradually increased from AK to SCC,and its activation status varied among different cutaneous squamous cell carcinoma cell lines.

Objective:To evaluate the effectiveness of a workshop-driven interactive teaching model in clinical alarm training for undergraduate nursing interns in the intensive care unit (ICU).Methods:A total of 120 undergraduate nursing students who interned in the ICU from November 2023 to April 2024 were enrolled and randomly assigned using a random number table into a control group ( n=60, traditional teaching) and an intervention group ( n=60, workshop-driven interactive teaching). Clinical alarm knowledge, attitudes, and practices (KAP); perception of patient safety culture; and training satisfaction were assessed before and after the training using validated questionnaires. Differences between groups were analyzed using independent sample t-test, paired sample t-test, chi-square test, and the Mann-Whitney U test with SPSS 22.0. Results:There were no significant differences between the two groups in clinical alarm KAP scores or patient safety culture perception scores before the training ( P>0.05). After the training, the intervention group showed significantly higher scores in clinical alarm KAP [(127.58±6.45) vs. (123.48±7.61), t=3.17, P=0.002] and patient safety culture perception [(99.44±9.17) vs. (95.45±12.03), t=-2.04, P=0.044] compared with the control group. Satisfaction with training content, teaching quality, and overall instructional design was significantly higher in the intervention group than in the control group ( P<0.05). Within-group comparisons showed that the intervention group had significant improvements in clinical alarm KAP [(127.58±6.45) vs. (120.10±10.25), t=-5.10, P<0.001] and patient safety culture perception [(99.44±9.17) vs. (94.46±12.12), t=-2.65, P=0.010] after training. No significant changes were observed in the control group after training ( P>0.05). Conclusions:The workshop-driven interactive teaching model can effectively enhance the clinical alarm KAP levels and patient safety culture perception among undergraduate nursing interns in the ICU. This teaching approach provides a scientific basis for optimizing clinical alarm education and cultivating high-quality nursing professionals.

AIM:To examine the impact of the transcription factor 7 analogue 2(TCF7L2)gene polymorphism on the hypoglycaemic effect of ex-enatide in patients with type 2 diabetes mellitus(T2DM).METHODS:A total of 100 newly diagnosed Han Chinese patients with T2DM who had not re-ceived any drug treatment were selected from the Affiliated Hospital of Xuzhou Medical University and treated with exenatide monotherapy for 6 months.The TCF7L2 rs290487 was genotyped by SnaPshot method,and blood glucose levels,lipids profiles and pancreatic function evaluation indica-tors were measured at baseline,3 months and 6 months after exenatide treatment.Multiple linear regression analysis was employed to assess the cor-relation between each indicator and the reduction in glycated hemoglobin(HbA1c)levels after 6 months of exenatide treatment.The expression of TCF7L2 protein in the plasma of T2DM patients was detected by enzyme-linked immunosorbent assay(ELISA)kit.Furthermore,western blotting was con-ducted to ascertain TCF7L2 expression in pancreat-ic tissues obtained from db/db mice and INS-1 cells cultured under high glucose conditions.Lentivirus transfection was used to overexpress or knock down TCF7L2 in insulinoma cell line(INS-1)cells,followed by measurement of KSIS activity and insu-lin content after a 24-hour intervention with exena-tide.RESULTS:The distribution pattern of TCF7L2 rs290487 was found to be in accordance with Har-dy-Weinberg equilibrium(P＞0.05).Following 6 months of exenatide treatment,there was a nota-ble reduction in blood glucose levels and an im-provement in lipid profiles when compared to base-line values.Additionally,there was a significant in-crease in the homeostasis model assessment of be-ta-cell function(HOMA-B)values.Patients with the TT genotype exhibited significantly lower postpran-dial plasma glucose(PPG)levels and HbA1c values compared to those with the CC or CT genotypes(P＜0.05).After adjusting for age,gender,body mass in-dex(BMI),and waist to hip ratio(WHR)in the mul-tiple linear regression model,a significant associa-tion was observed between the rs290487 TT geno-type,baseline HbA1c levels,and family history of diabetes with the reduction in HbA1c after six months of exenatide treatment(P＜0.05).Further-more,individuals with the rs290487 TT genotype demonstrated a notable elevation in TCF7L2 expres-sion in plasma among T2DM patients in comparison to those with the CC genotype(P＜0.05).In particu-lar,pancreatic tissue from db/db mice exhibited markedly elevated TCF7L2 expression compared to db/m mice.However,this up-regulation was re-versed by exenatide treatment.Similarly,INS-1 cells cultured under high glucose conditions dem-onstrated an increase in TCF7L2 expression,which was ameliorated upon exenatide administration.The knockdown of TCF7L2 using shRNA enhanced the KSIS function of pancreatic β cells and aug-mented the insulinotropic effect of exenatide.Con-versely,the upregulation of TCF7L2 impaired the KSIS function of pancreatic β cells and attenuated the insulinotropic effect of exenatide.CONCLU-SION:The TCF7L2 rs290487 gene polymorphism is closely associated with the hypoglycaemic efficacy of exenatide therapy.The risk allele C may diminish the effectiveness of exenatide by impacting the lev-els of PPG and HbA1c in T2DM patients.The muta-tion at TCF7L2 rs290487 site(C→T)influenced the expression of TCF7L2 protein.By exerting its regula-tory effect,exenatide may be capable of regulating the impact of TCF7L2 on the function of pancreaticβ cells.

Background: Hypertension is a major risk factor for cardiovascular diseases, including AF, which is one of the most common cardiac arrhythmias globally. AF is strongly associated with an increased risk of stroke, heart failure (HF), and cardiovascular mortality. Although intensive blood pressure lowering has been shown to reduce adverse cardiovascular events, its effect on the risk of AF remains debated. Some studies suggest a beneficial effect, whereas others are inconclusive. Therefore, a comprehensive review and meta-analysis are needed to clarify these effects. Objective: This study aims to evaluate the impact of intensive blood pressure lowering on the incidence of atrial fibrillation (AF) in hypertensive patients. Methods: We performed a systematic review and meta-analysis by searching PubMed, EMBASE, Scopus, Web of Science, and the Cochrane Library up to September 2, 2024, for randomized controlled trials comparing intensive blood pressure lowering with standard treatment in hypertensive patients. Studies were included if participants were 40 year or older with systolic blood pressure between 130 and 180 mm Hg (1 mm Hg≈0.133 kPa). Data extraction was conducted by 2 independent researchers, and statistical analysis was performed using Review Manager (RevMan) 5.4. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. A random-effects model was applied if heterogeneity was detected (I > 50%). Results: A total of 6 randomized controlled trials involving 34,824 participants were included in the analysis. Intensive blood pressure lowering significantly reduced the risk of new-onset AF compared with standard treatment (RR = 0.76, 95% CI = 0.62-0.93, p < 0.01, I = 0%). Reductions were also observed in stroke (RR = 0.71, 95% CI = 0.58-0.87, p < 0.005, I = 7%), HF (RR = 0.67, 95% CI = 0.45-0.99, p = 0.05, I = 53%), and nonfatal coronary events (RR = 0.80, 95% CI = 0.70-0.92, p < 0.005, I = 39%). However, intensive blood pressure lowering had no significant effect on cardiovascular mortality or all-cause mortality compared with standard treatment. Discussion: Intensive blood pressure lowering significantly reduces the risk of AF and other cardiovascular events, such as stroke, HF, and nonfatal coronary events, particularly among high-risk hypertensive patients. These findings support the potential benefits of intensive blood pressure management in reducing AF incidence and improving overall cardiovascular outcomes, but the evidence is limited.

Tumor ribonucleic acid(RNA)vaccines,which are emerging as promising cancer immunotherapies,have achieved significant technological breakthroughs during the COVID-19 pandemic.These vaccines activate immune responses through precise antigen expression.However,they face challenges such as suboptimal delivery efficiency and insufficient immunogenicity.Current studies focus on three design strategies:conventional messengerribonucleic acid(mRNA),self-amplifying mRNA,and circular RNA(circRNA)vaccines coupled with lipid nanoparticles(LNP)and polyethylene glycol(PEG)optimization for enhanced delivery.Clinical trials have demonstrated the synergistic effic-acy of RNA vaccines in combination with immune checkpoint inhibitors,chemotherapy,or oncolytic viruses.However,clinical translation is hindered by the complexity of antigen selection and storage stability limitations.In this review,we systematically summarize the recent clin-ical advancements in tumor RNA vaccines,analyze their technical challenges,and propose innovative strategies to address the current thera-peutic bottlenecks to guide future research and clinical applications.

Objective:To provide a scoping review of domestic and international studies on the influencing factors of frailty in stroke inpatients, and to provide guidance for interventional studies on debility in stroke inpatients in China.Methods:A systematic search of domestic and international literature databases, including China National Knowledge Infrastructure, WanFang, VIP, China Biomedical Literature Database, PubMed, Web of Science, Embase, Cochrane Library, CINAHL was conducted about the status and its influencing factors of frailty in stroke inpatients. The retrieval time limit was from database establishment to November 23, 2023. The included literature was extracted, analyzed, and summarized according to the reporting specifications of the scope review guidelines.Results:Thirty-six articles were included, all of the 36 papers reported the prevalence of frailty in patients with stroke. The top three countries with the highest prevalence were China (15.3%-86.9%), the United Kingdom (28%-78%), and Italy (31.37%). The risk factors of stroke frailty were categorized mainly into 4 themes: social demographic factors, physical health factors, disease-related factors, and psychological and social background factors.Conclusions:The confidence of frailty in stroke patients of a higher level at home and abroad, and the risk factors involved are complex and diverse. It is suggested that future studies need to conduct large-sample, multicenter longitudinal studies to clarify the causal relationship, strengthen the exploration of controversial factors of stroke debility, and carry out more targeted intervention studies, so as to reduce the incidence of frailty and improve the recovery process of patients.
