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.

PURPOSE:
We carried out the study aiming to explore and analyze the risk factors, the distribution of pathogenic bacteria, and their antibiotic-resistance characteristics influencing the occurrence of surgical site infection (SSI), to provide valuable assistance for reducing the incidence of SSI after traumatic fracture surgery.
METHODS:
A retrospective case-control study enrolling 3978 participants from January 2015 to December 2019 receiving surgical treatment for traumatic fractures was conducted at Tangdu Hospital of Air Force Medical University. Baseline data, demographic characteristics, lifestyles, variables related to surgical treatment, and pathogen culture were harvested and analyzed. Univariate analyses and multivariate logistic regression analyses were used to reveal the independent risk factors of SSI. A bacterial distribution histogram and drug-sensitive heat map were drawn to describe the pathogenic characteristics.
RESULTS:
Included 3978 patients 138 of them developed SSI with an incidence rate of 3.47% postoperatively. By logistic regression analysis, we found that variables such as gender (males) (odds ratio (OR) = 2.012, 95% confidence interval (CI): 1.235 - 3.278, p = 0.005), diabetes mellitus (OR = 5.848, 95% CI: 3.513 - 9.736, p < 0.001), hypoproteinemia (OR = 3.400, 95% CI: 1.280 - 9.031, p = 0.014), underlying disease (OR = 5.398, 95% CI: 2.343 - 12.438, p < 0.001), hormonotherapy (OR = 11.718, 95% CI: 6.269 - 21.903, p < 0.001), open fracture (OR = 29.377, 95% CI: 9.944 - 86.784, p < 0.001), and intraoperative transfusion (OR = 2.664, 95% CI: 1.572 - 4.515, p < 0.001) were independent risk factors for SSI, while, aged over 59 years (OR = 0.132, 95% CI: 0.059 - 0.296, p < 0.001), prophylactic antibiotics use (OR = 0.082, 95% CI: 0.042 - 0.164, p < 0.001) and vacuum sealing drainage use (OR = 0.036, 95% CI: 0.010 - 0.129, p < 0.001) were protective factors. Pathogens results showed that 301 strains of 38 species of bacteria were harvested, among which 178 (59.1%) strains were Gram-positive bacteria, and 123 (40.9%) strains were Gram-negative bacteria. Staphylococcus aureus (108, 60.7%) and Enterobacter cloacae (38, 30.9%) accounted for the largest proportion. The susceptibility of Gram-positive bacteria to Vancomycin and Linezolid was almost 100%. The susceptibility of Gram-negative bacteria to Imipenem, Amikacin, and Meropenem exceeded 73%.
CONCLUSION
Orthopedic surgeons need to develop appropriate surgical plans based on the risk factors and protective factors associated with postoperative SSI to reduce its occurrence. Meanwhile, it is recommended to strengthen blood glucose control in the early stage of admission and for surgeons to be cautious and scientific when choosing antibiotic therapy in clinical practice.

Journal of Experimental Hematology 2025;33(1):198-205
OBJECTIVE:
To analyze the occurrence of arterial events and platelet parameters in patients with polycythemia vera (PV) and essential thrombocythemia (ET), and to explore the characteristics of platelet parameters in patients with PV and ET and their relationship with arterial complications.
METHODS:
The clinical and laboratory data of newly diagnosed PV and ET patients who visited the Department of Hematology, Beijing Anzhen Hospital, Capital Medical University from August 2017 to August 2022 were retrospectively analyzed.
RESULTS:
86 MPN patients (46 males and 40 females) were enrolled, including 44 PV patients and 42 ET patients, with an median age of 61(23-83) years. The mutation rate of JAK2V617F gene, the number of megakaryocytes in bone marrow, the incidence of splenomegaly, and the levels of white blood cell count (WBC), hemoglobin (HGB), hematocrit (HCT), platelet distribution width (PDW), mean platelet volume (MPV), platelet-large cell ratio (P-LCR) in PV patients were significantly higher than those in ET patients (P < 0.05), while the levels of PLT and PCT were significantly lower than those in ET patients (P < 0.01). 22 cases (50%) of PV patients were complicated with arterial events, of which 12 had arterial stenosis in≥2 locations. Among arterial events, the PDW of PV patients with ischemic stroke was greater than that of PV patients without ischemic stroke (P =0.003), and the PDW of PV patients with arterial stenosis in≥2 locations was greater than that of PV patients with arterial stenosis in≤1 location (P =0.037). 23 cases (54.8%) of ET patients were complicated with arterial events, and 7 cases had arterial stenosis in≥2 locations. In arterial events, the PCT of ET patients complicated with ischemic stroke was greater than that of ET patients without ischemic stroke (P =0.037), and the PCT of ET patients with≥2 locations of arterial stenosis was greater than that of ET patients with≤1 location of arterial stenosis (P =0.049). The binary logistic regression analysis showed that elevated PDW and PCT were risk factors for ischemic stroke in PV and ET patients, respectively (P < 0.05).
CONCLUSION
The platelet parameters of PV and ET patients exhibit significantly different characteristics. Elevated PDW and PCT can predict a higher risk of ischemic stroke in PV and ET patients, respectively.

Wastewater-based epidemiology has emerged as a transformative surveillance tool for estimating substance consumption and monitoring disease prevalence, particularly during the COVID-19 pandemic. It enables the population-level monitoring of illicit drug use, pathogen prevalence, and environmental pollutant exposure. In this perspective, we summarize the key challenges specific to the Chinese context: (1) Sampling inconsistencies, necessitating standardized 24-hour composite protocols with high-frequency autosamplers (≤ 15 min/event) to improve the representativeness of samples; (2) Biomarker validation, requiring rigorous assessment of excretion profiles and in-sewer stability; (3) Analytical method disparities, demanding inter-laboratory proficiency testing and the development of automated pretreatment instruments; (4) Catchment population dynamics, reducing estimation uncertainties through mobile phone data, flow-based models, or hydrochemical parameters; and (5) Ethical and data management concerns, including privacy risks for small communities, mitigated through data de-identification and tiered reporting platforms. To address these challenges, we propose an integrated framework that features adaptive sampling networks, multi-scale wastewater sample banks, biomarker databases with multidimensional metadata, and intelligent data dashboards. In summary, wastewater-based epidemiology offers unparalleled scalability for equitable health surveillance and can improve the health of the entire population by providing timely and objective information to guide the development of targeted policies.

Objective:To investigate the expressions and clinical significances of histone marks H3K9me3 and H3K27me3 in colorectal cancer.Methods:A retrospective case-control study was conducted. The clinical data of 98 patients with colorectal cancer in Shanxi Province Cancer Hospital from May 2008 to July 2017 were retrospectively analyzed, including 35 patients in the non-metastatic operation-only group, 29 patients in the synchronous hepatic oligometastasis group and 34 patients in the extensive metastasis group, and 33 patients with benign colorectal lesions who underwent colonoscopy in 2017 were selected as the control group. Immunohistochemical assay was used to detect the expressions of H3K9me3 and H3K27me3 proteins in each group, and the expressions of H3K9me3 and H3K27me3 proteins in colorectal cancer patients with different clinicopathological features were analyzed. Kaplan-Meier method was used for survival analysis and log-rank test was performed.Results:The positive expression rate of H3K9me3 protein in colorectal cancer group was 11.2% (11/98), which was lower than that in control group [60.6% (22/33)] ( χ2 = 33.33, P < 0.001); the positive expression rate of H3K27me3 protein in colorectal cancer group was 10.6% (13/98), which was lower than that in control group [97.0% (32/33)] ( χ2 = 76.70, P < 0.001). The positive expression rates of H3K9me3 protein were 60.6% (20/33), 17.1% (6/35), 10.3% (3/29) and 5.9 % (2/34) in the control group, the non-metastatic operation-only group, the synchronous hepatic oligometastasis group and the extensive metastasis group, respectively, and the difference was statistically significant ( χ2 = 26.10, P < 0.001); the positive expression rates of H3K27me3 protein were 97.0% (32/33), 14.3% (5/35), 20.7% (6/29) and 5.9% (2/34), respectively, and the difference was statistically significant ( χ2 = 44.16, P < 0.001). The positive expression rate of H3K27me3 in colorectal cancer tissues of patients with lymph node metastasis degree ≤0.2 was higher than that of patients with lymph node metastasis degree >0.2 [22.4% (11/49) vs. 4.2% (2/48), χ2 = 6.98, P = 0.008]. The median overall survival (OS) time of H3K9me3 positive and negative colorectal cancer patients was 77.0 months (95% CI: 10.6-143.3 months) and 34.0 months (95% CI: 25.5-42.5 months), respectively, and there was no significant difference in OS between the two groups ( P = 0.078). The median OS time of H3K27me3 positive and negative colorectal cancer patients was 39.0 months (95% CI: 15.3- 62.7 months) and 34.0 months (95% CI: 24.3-43.7 months), respectively, and there was no significant difference in OS between the two groups ( P = 0.524). Conclusions:The expressions of H3K9me3 and H3K27me3 in colorectal cancer tissues are lower than those in colorectal benign lesions, and gradually decrease with occurrence of liver metastasis and extensive metastasis. H3K9me3 and H3K27me3 may be potential cancer suppressor factors.
