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.

Objective To investigate the relationship between prolactin and mild cognitive impairment(MCI)in postmenopausal women with type 2 diabetes mellitus(T2DM).Methods A total of 319 postmenopausal women with T2DM who were hospitalized in the Department of Endocrinology,Drum Tower Hospital,Affiliated Hospital of Medical School,Nanjing University were enrolled in this study from August 2016 to October 2023.All the patients were divided into two groups according whether they had MCI:T2DM group(n=161)and MCI group(n=158).Differences in clinical characteristics were compared between the two groups.Pearson correlation was used to analyze the correlation between sex hormones and cognitive domains,and Logistic regression analysis was used to evaluate the influencing factors for MCI development.Results Serum prolactin levels were significantly lower in the MCI group than in the T2DM group[(5.5±2.1)vs(7.2±2.9)μg/L,P<0.05].Serum prolactin level was positively correlated with mini-mental state examination score,Montreal cognitive assessment score,immediate memory score,visuopatial constructional score,attention score and hippocampal volume(P<0.05),and negatively correlated with processing speed test(time)and executive function test(time)(P<0.05).Logistic regression analysis demonstrated that serum prolactin level was an influencing factor for the risk of MCI in postmenopausal women with T2DM(OR 0.715,95%CI 0.605～0.845,P<0.01).Conclusions The decrease of serum prolactin level is associated with an increased risk of MCI in postmenopausal women with T2DM.

As the lifestyle of modern people changes,genetic factors continue to become more prominent,and the impact of environmental and water pollution,the incidence of intestinal diseases(colorectal cancer,inflammatory bowel disease,irritable bowel syndrome,chronic constipation,etc.)is increasing.It not only seriously endangers the health of the population,but also consumes a large amount of medical resources.Paeonol,as a class of small molecule phenolic compounds,has a wide range of biological activities,such as anti-inflammatory,anti-viral,anti-tumor,anti-allergic,immune regulation,cardiovascular and cerebrovascular protection,etc.The mechanism and experimental research on the effect of paeonol in preventing and treating intestinal diseases based on the"Brain-Gut-Bacteria axis"are also in-depth.This article aims to systematically review and sort out the latest progress in this field,with a view to providing certain ideas and methods for the precise treatment of intestinal diseases and the development of new drugs.

Objective:To investigate the correlation of systemic immune inflammatory index (SII) and monocyte-to-lymphocyte ratio (MLR) with chronic kidney disease-mineral and bone disorder (CKD-MBD) in patients with stage 5 chronic kidney disease (CKD).Methods:A cross-sectional survey method was used to select 152 patients with stage 5 CKD who received treatment in the Department of Nephrology, Hefei First People's Hospital from January 2023 to January 2024 as research subjects. Based on the patients' intact parathyroid hormone (iPTH) levels, they were divided into three groups: low iPTH group ( n = 63), normal iPTH group ( n = 46), and high iPTH group ( n = 43). The differences in SII and MLR among the three groups were analyzed. The relationship between SII and the occurrence of high iPTH was analyzed to assess the predictive efficacy of SII for high iPTH. Results:Among the 152 patients with stage 5 CKD, the low iPTH group accounted for 41.45% (63/152), the normal iPTH group for 30.26% (46/152), and the high iPTH group for 28.29% (43/152). The prevalence of hypertension in each group was as follows: 85.71% (54/63) in the low iPTH group, 89.13% (41/46) in the normal iPTH group, and 60.77% (30/43) in the high iPTH group ( χ2 = 6.60, P = 0.037). Other parameters showed significant differences among the groups: neutrophil count was 3.60 (2.94, 4.79) × 10 9/L in the low iPTH group, 4.08 (3.16, 4.88) × 10 9/L in the normal iPTH group, and 5.21 (4.08, 6.75) ×10 9/L in the high iPTH group ( Z = 25.64, P < 0.001); lymphocyte count was 1.51 (1.13, 1.85) × 10 9/L, 1.18 (1.00, 1.68) × 10 9/L, and 1.10 (0.75, 1.66) × 10 9/L, respectively ( Z = 8.25, P = 0.016); monocyte count was 0.47 (0.36, 0.62) × 10 9/L, 0.53 (0.42, 0.70) × 10 9/L, and 0.43 (0.33, 0.54) × 10 9/L, respectively ( Z = 8.15, P = 0.017); serum albumin levels were (37.26 ± 5.77) g/L, (36.31 ± 5.68) g/L, and (41.53 ± 4.90) g/L, respectively ( t = 10.85, P < 0.001); creatinine levels were 214.00 (148.00, 343.00) μmol/L, 462.00 (338.50, 682.25) μmol/L, and 835.50 (702.50, 960.75) μmol/L, respectively ( Z = 74.65, P < 0.001); serum calcium levels were 2.19 (2.11, 2.28) mmol/L, 2.16 (2.04, 2.26) mmol/L, and 2.32 (2.10, 2.49) mmol/L, respectively ( Z = 11.77, P = 0.003); serum phosphate levels were 1.21 (1.04, 1.49) mmol/L, 1.47 (1.27, 1.83) mmol/L, and 1.99 (1.65, 2.49) mmol/L, respectively ( Z = 48.72, P < 0.001); SII values were 362.75 (292.68, 639.92), 491.03 (380.12, 715.77), and 851.50 (525.23, 1 149.72), respectively ( Z = 33.02, P < 0.001); and MLR values were 0.30 (0.24, 0.43), 0.43 (0.30, 0.52), and 0.35 (0.28, 0.61), respectively ( Z = 9.02, P = 0.011). All differences among the three groups were statistically significant (all P < 0.05). There were no statistically significant differences among the groups regarding age, gender, height, body mass index, smoking history, alcohol consumption history, prevalence of diabetes, platelet count, serum total protein, uric acid, triglycerides, total cholesterol, high-density lipoprotein cholesterol, or low-density lipoprotein cholesterol (all P > 0.05). Multivariate logistic regression analysis indicated that elevated SII ( OR = 1.003, P = 0.024) was an independent risk factor for increased serum iPTH ( P < 0.05). Receiver operating characteristic analysis showed that the area under the curve for SII predicting high iPTH in patients with stage 5 CKD was 0.774 ( P < 0.001). Conclusions:In patients with stage 5 CKD, elevated creatinine, serum calcium, and SII are independent risk factors for increased serum iPTH, and SII has predictive value for the occurrence of high iPTH in patients with CKD.

Objective:To analyze the risk factors associated with intradialytic hypotension (IDH) in patients undergoing maintenance hemodialysis (MHD).Methods:This study used a cross-sectional design and included 150 adult patients who underwent MHD at The Third Affiliated Hospital of Anhui Medical University from January 2023 to March 2024. Relevant clinical data were collected to analyze the occurrence of IDH in patients undergoing MHD over 3 months, and the associated risk factors.Results:Among the 150 patients undergoing MHD, there were 67 in the IDH group and 83 in the non-IDH group. The IDH group had a higher fibrinogen/albumin ratio (FAR) [89.41 (73.30, 114.50) vs. 76.56 (65.80, 89.60), χ2 = -3.55, P < 0.001], an older age [(68.46 ± 14.10) years vs. (61.30 ± 12.23) years, t = -3.33, P = 0.001], a longer dialysis duration [(4 (3.5, 4.0) hours vs. (4 (4.0, 4.0) hours), U = -2.11, P = 0.044], a greater ultrafiltration volume [(2.20 ± 0.74) L vs. (1.92 ± 0.82) L, t = -2.16, P = 0.032], a higher ultrafiltration rate [(8.90 ± 2.64) mL·h?1·kg?1 vs. (7.75 ± 2.91) mL·h?1·kg?1, t = -2.51, P = 0.013], and a higher ultrafiltration volume/dry body mass ratio [(33.75 ± 9.76) mL/kg vs. (30.21 ± 11.39) mL/kg, t = -2.11, P = 0.046] compared with the non-IDH group. In the IDH group, the proportion of patients with primary chronic glomerulonephritis was lower (19.4% vs. 37.3%, χ2 = 5.76, P = 0.016), fibrinogen levels were higher [(3.63 (3.15, 4.50) μg/L vs. (3.34 (2.90, 3.74) μg/L, U = -2.61, P = 0.009], albumin levels were lower [(41.26 ± 4.03) g/L vs. (43.42 ± 4.29) g/L, t = 3.15, P = 0.002], high-density lipoprotein cholesterol (HDL-C) levels were lower [0.90 (0.77, 1.09) mmol/L vs. 1.05 (0.84, 1.34) mmol/L, U = -2.77, P = 0.006], and C-reactive protein levels were higher [5.92 (2.79, 9.61) mg/L vs. 2.70 (0.99, 6.49) mg/L, U = -2.27, P = 0.023] compared with the non-IDH group. Multivariate logistic regression analysis indicated that higher FAR values ( OR = 1.030, P = 0.025), a history of chronic glomerulonephritis ( OR = 10.408, P = 0.012), older age ( OR = 1.062, P = 0.043), a high ultrafiltration volume/dry body mass ratio ( OR = 1.072, P = 0.037), and low HDL-C levels ( OR = 0.046, P = 0.015) are independent risk factors for IDH. The area under the receiver operating characteristic curve for FAR predicting IDH was 0.699 (95% CI: 0.571-0.827, P = 0.003). The combination of age, chronic glomerulonephritis, ultrafiltration volume/dry body mass ratio, HDL-C levels, and FAR for predicting IDH resulted in a receiver operating characteristic curve area of 0.839 (95% CI: 0.750-0.929, P < 0.001). Conclusions:Among the risk factors for IDH in patients undergoing MHD, FAR is independently associated with an increased risk of IDH and serves as a valuable predictor for its occurrence in these patients.

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.

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.

Objective:To explore the value of cardiac magnetic resonance imaging (CMR) derived left ventricular late gadolinium enhancement (LV LGE) for the primary prevention of malignant ventricular arrhythmias in arrhythmogenic right ventricular cardiomyopathy (ARVC) patients.Methods:This was a single-center retrospective study. Consecutive ARVC patients who underwent CMR at Fuwai Hospital between January 2016 and September 2020, with no history of malignant ventricular arrhythmias at diagnosis, were enrolled. Clinical data and CMR characteristics were collected. The primary endpoint was defined as new-onset malignant ventricular arrhythmias related events, including sustained ventricular tachycardia, ventricular fibrillation/flutter, sudden cardiac death, cardiac arrest, and appropriate implantable cardioverter-defibrillator discharge. Follow-up via telephone interviews and medical records was conducted to confirm endpoint occurrences, and patients were categorized into event-free and event groups based on endpoint status. Univariable and multivariable Cox regression analysis were performed to identify independent risk factors for malignant ventricular arrhythmias in ARVC patients. Subgroup analyses were conducted based on the ARVC 5-year risk score (cutoff: 25%) and the median value of LV LGE percentage (cutoff: 13%). Kaplan-Meier curves were plotted, and log-rank tests were used to compare the difference in the incidence of primary endpoint events between subgroups. Receiver operating characteristic curves and likelihood ratio test were used to evaluate the incremental prognostic value of LV LGE percentage beyond the ARVC 5-year risk score.Results:A total of 172 ARVC patients were enrolled, aged (39.0±16.6) years, including 73 females (42.4%). During a follow-up of 53.1 (25.4, 76.9) months, 51 patients (29.7%) experienced malignant ventricular arrhythmias related events, including 3 cases of sudden cardiac death, 1 cardiac arrest, 33 sustained ventricular tachycardia and 14 appropriate implantable cardioverter-defibrillator discharges. Multivariable Cox regression analysis indicated that the ARVC 5-year risk score ( HR=1.028, 95% CI 1.015-1.041, P<0.001) and LV LGE percentage ( HR=1.059, 95% CI 1.032-1.087, P<0.001) were independent risk factors of the primary endpoint events. Kaplan-Meier analysis using composite stratification (ARVC 5-year risk score cutoff: 25%; LV LGE percentage cutoff: 13%) demonstrated that patients with both high risk scores (≥25%) and extensive LV LGE (≥13%) had the highest risk of primary endpoint events. Notably, among patients with ARVC 5-year risk scores <25%, those with LV LGE≥13% had a higher incidence of primary endpoint events than those without (log-rank P=0.037). The composite prediction model combining the 5-year risk score and left ventricular LGE percentage demonstrated significantly improved predictive performance (area under the curve ( AUC)=0.82, 95% CI 0.75-0.90; likelihood ratio test all P<0.001) compared to single-variable models (left ventricular LGE percentage alone: AUC=0.71, 95% CI 0.63-0.82, P=0.01; 5-year risk score alone: AUC=0.71, 95% CI 0.62-0.81, P=0.02). Conclusion:LV LGE percentage independently predict new-onset malignant ventricular arrhythmias in ARVC patients and provided incremental prognostic value based on the existing ARVC 5-year risk score.

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 investigate the relationship between prolactin and mild cognitive impairment(MCI)in postmenopausal women with type 2 diabetes mellitus(T2DM).Methods A total of 319 postmenopausal women with T2DM who were hospitalized in the Department of Endocrinology,Drum Tower Hospital,Affiliated Hospital of Medical School,Nanjing University were enrolled in this study from August 2016 to October 2023.All the patients were divided into two groups according whether they had MCI:T2DM group(n=161)and MCI group(n=158).Differences in clinical characteristics were compared between the two groups.Pearson correlation was used to analyze the correlation between sex hormones and cognitive domains,and Logistic regression analysis was used to evaluate the influencing factors for MCI development.Results Serum prolactin levels were significantly lower in the MCI group than in the T2DM group[(5.5±2.1)vs(7.2±2.9)μg/L,P<0.05].Serum prolactin level was positively correlated with mini-mental state examination score,Montreal cognitive assessment score,immediate memory score,visuopatial constructional score,attention score and hippocampal volume(P<0.05),and negatively correlated with processing speed test(time)and executive function test(time)(P<0.05).Logistic regression analysis demonstrated that serum prolactin level was an influencing factor for the risk of MCI in postmenopausal women with T2DM(OR 0.715,95%CI 0.605～0.845,P<0.01).Conclusions The decrease of serum prolactin level is associated with an increased risk of MCI in postmenopausal women with T2DM.
