Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

Ulcerative colitis (UC) is a chronic and non-specific inflammatory bowel disease (IBD). Huanglian Ganjiang decoction (HGD), derived from ancient book Beiji Qianjin Yao Fang, has demonstrated efficacy in treating UC patients traditionally. Previous research established that the compatibility of cold herb Coptidis Rhizoma + Phellodendri Chinensis Cortex (CP) and hot herb Angelicae Sinensis Radix + Zingiberis Rhizoma (AZ) in HGD synergistically improved colitis mice. This study investigated the compatibility mechanisms through which CP and AZ regulated inflammatory balance in colitis mice. The experimental colitis model was established by administering 3% dextran sulphate sodium (DSS) to mice for 7 days, followed by CP, AZ and CPAZ treatment for an additional 7 days. M1/M2 macrophage polarization levels, glucose metabolites levels and pyruvate dehydrogenase kinase 4 (PDK4) expression were analyzed using flow cytometry, Western blot, immunofluorescence and targeted glucose metabolomics. The findings indicated that CP inhibited M1 macrophage polarization, decreased inflammatory metabolites associated with tricarboxylic acid (TCA) cycle, and suppressed PDK4 expression and pyruvate dehydrogenase (PDH) (Ser-293) phosphorylation level. AZ enhanced M2 macrophage polarization, increased lactate axis metabolite lactate levels, and upregulated PDK4 expression and PDH (Ser-293) phosphorylation level. TCA cycle blocker AG-221 and adeno-associated virus (AAV)-PDK4 partially negated CP's inhibition of M1 macrophage polarization. Lactate axis antagonist oxamate and PDK4 inhibitor dichloroacetate (DCA) partially reduced AZ's activation of M2 macrophage polarization. In conclusion, the compatibility of CP and AZ synergistically alleviated colitis in mice through M1/M2 macrophage polarization balance via PDK4-mediated glucose metabolism reprogramming. Specifically, CP reduced M1 macrophage polarization by restoration of TCA cycle via PDK4 inhibition, while AZ increased M2 macrophage polarization through activation of PDK4/lactate axis.

Objective To evaluate the effectiveness of active screening in improving the detection rate of carbape-nem-resistant Enterobacterales(CRE)in the intensive care units(ICUs).Methods From July 2023 to June 2024,active screening of rectal swab CRE was conducted on ICU patients in 10 hospitals.ICU patients who underwent ac-tive screening from July 2023 to June 2024 were selected as the study group,while those who did not undergo active screening from July 2022 to June 2023 were selected as the control group.Difference in CRE detection rates between the two groups of patients was compared.Results A total of 7 803 ICU patients were included in the study group,744 CRE strains were detected,with a detection rate of 9.53％,out of which 304 CRE strains were detected through routine detection(detection rate 3.90％),3 707 patients underwent active screen,440 CRE strains were detected(detection rate 11.87％).7 561 ICU patients were included in the control group,out of which 250 CRE strains were detected through routine detection,with a detection rate of 3.31％.There was a statistically significant difference in the overall detection rate of CRE between two groups of patients(x2=246.18,P＜0.001).In the study group,CRE detection rate of active screening(11.87％)was higher than that of routine detection(3.90％),with statistically significant difference(x2=264.26,P＜0.001).A total of 17 CRE strains were detected from the study group.The proportions of Klebsiella pneumoniae(80.92％vs 73.41％)and Serratia marcescens(2.30％vs0.23％)in the routine detection group were both higher than in the active screening group,while the proportion of Escherichia coli in the routine detection group was lower(8.22％vs 19.55％),all with statistically significant differences(all P＜0.05).Conclusion The prevalence of CRE in ICUs is relatively high,with a wide range of bac-terial species.Active screening can improve the detection rate of CRE.

Objectives:To investigate the clinical value of cardiac magnetic resonance imaging(CMR)feature-tracking strain analysis in risk stratification of diabetic heart failure with preserved ejection fraction(HFpEF).Methods:In this retrospective study,a total of 215 patients with diabetic HFpEF who underwent CMR at Chinese Academy of Medical Sciences Fuwai Hospital from January 2012 to December 2018 were included.Myocardial strain parameters were calculated using CMR feature-tracking technology.Patients were followed up by medical records or telephone calls.Composite endpoint event,all-cause death or heart failure hospitalization during follow-up were recorded.Patients were divided into event group and event-free group.Univariable and multivariable Cox proportional hazard regression analyses were performed to determine the risk factors for the outcomes in diabetic HFpEF.The effects of hypertension and obesity on the prognosis of diabetic HFpEF patients and whether they affect the prognostic value of CMR feature-tracking strain analysis were also analyzed.Results:During a follow-up of(7.1±1.8)years,93(43.3%)patients had endpoint events(event group),including 28 all-cause deaths and 65 heart failure hospitalization.Compared with the event-free group(n=122),patients in the event group had significantly lower left ventricular ejection fraction,higher prevalence and extent of late gadolinium enhancement,and significantly reduced global longitudinal strain(GLS),global circumferential strain,global radial strain,and global systolic longitudinal strain rate(all P<0.05).The absolute GLS value was significantly lower in event group than in event-free group,regardless of the presence of hypertension and obesity.Multivariate Cox regression analysis showed that estimated glomerular filtration rate(HR=0.983,95%CI:0.972-0.993,P=0.001),left atrial volume index(HR=1.015,95%CI:1.005-1.026,P=0.004),and GLS(HR=1.142,95%CI:1.060-1.231,P<0.001)were independent risk factors for adverse cardiovascular events in diabetic HFpEF patients.However,adjusted N-terminal pro-brain natriuretic peptide was not an independent prognostic factor.The cut-offvalue of GLS to predict outcome was-14.09%from ROC curve analysis.The Kaplan-Meier curve showed that in patients with and without hypertension and obesity,patients with the GLS>-14.09%had lower event-free survival compared to patients with GLS≤-14.09%(all P<0.05),and the ability of GLS to predict adverse outcomes was not affected by hypertension and obesity.Conclusions:GLS obtained by CMR feature-tracking strain analysis is an independent predictor of adverse outcomes in diabetic HFpEF,and its ability to predict adverse outcomes is independent of hypertension and obesity.

OBJECTIVE To assess the influence of hospital-associated carbapenem-resistant Klebsiella pneumoniae(CRKP)infection on direct economic burden of the intensive care unit(ICU)patients so as to provide bases for optimization of infection control strategies.METHODS A total of 242 patients who were detected with CRKP were chosen from 5426 patients who were hospitalized in ICUs of Fuyang People's Hospital from Jan.2021 to Dec.2024,the enrolled patients were recruited as the research subjects and were divided into the CRKP infection group with 48 cases and the non-CRKP infection group with 194 cases according to the status of hospital-associated infec-tions.The direct economic burden due to the CRKP infection was analyzed by propensity score matching(PSM)method.RESULTS The isolation rate of CRKP was 39.93％(242/606),the incidence of hospital-associat-ed infections was 0.88％(48/5426),ventilator-associated pneumonia were dominant,accounting for 43.75％.To-tally 44 pairs were matched in a 1∶1 ratio by PSM.After the matching,the median total hospitalization costs of the CRKP infection group was 226,079.17 yuan per case,more than 121,615.56 yuan per case in the non-CRKP infection group(P＜0.05).The burden of western medicine costs was the highest composition of the costs,which was increased by 39,166.45 yuan per case,and the cost of antibiotics was increased by 5251.20 yuan per case(all P＜0.05).The length of hospital stay extended by 11.00 days per case due to hospital-associated infec-tions(40.00 days vs.29.00 days,P＜0.05).CONCLUSIONS The direct economic burden of the ICU patients is re-markably increased due to the hospital-associated CRKP infection,which is mainly from the increase of west-ern medicine costs and extension of hospital stay.It is crucial to optimize the use of antibiotics and reduce the inva-sive procedures(such as removing ventilators as early as possible)so as to reduce the direct economic burden.

Objective:This study aimed to systematically evaluate the efficacy of glucagon-like peptide-1(GLP-1) receptor agonists and multi-target analogs on weight reduction and cardiometabolic outcomes in non-diabetic individuals with obesity, and to compare the efficacy and safety across different GLP-1 receptor agonists.Methods:Randomized controlled trials(RCTs) published between January 2000 and March 2025 were identified through a systematic search of CNKI, Wanfang, Web of Science, PubMed, and Cochrane databases. Two reviewers independently screened the studies, extracted data, and assessed methodological quality. Meta-analysis was performed using RevMan 5.4.1 software. Results:A total of 16 RCTs involving 11 032 non-diabetic individuals with obesity were included. Meta-analysis showed that GLP-1 receptor agonists significantly reduced body weight(ΔWeight=-8.71 kg, 95% CI -10.68 to -6.74, P<0.001) and BMI(ΔBMI=-3.01 kg/m 2, 95% CI -3.77 to -2.25, P<0.001), as well as improved systolic blood pressure(ΔSBP=-4.13 mmHg, 1 mmHg=0.133 kPa, 95% CI -4.87 to -3.39, I2=60%) and diastolic blood pressure(ΔDBP=-1.39 mmHg, 95% CI -2.32 to -0.46, I2=95%). Tirzepatide showed the most pronounced effects on both weight and blood pressure reduction. In addition, GLP-1 receptor agonists significantly lowered LDL-C, TC, and TG, while moderately increasing HDL-C levels. In terms of safety, GLP-1 receptor agonists were associated with an increased risk of gastrointestinal adverse events, but did not significantly increase the risk of hypoglycemia. Conclusion:GLP-1 receptor agonists are effective in reducing weight, BMI, and blood pressure, and in improving lipid profiles in non-diabetic individuals with obesity. However, gastrointestinal side effects should be closely monitored. Given the variability in efficacy and safety among various GLP-1 receptor agonists, personalized treatment approaches are recommended.
