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.

ObjectiveTo investigate the influence of empagliflozin combined with donafenib or lenvatinib on the pharmacokinetic parameters of each drug， and to provide a reference for combined medication in clinical practice. MethodsA total of 48 healthy male Sprague-Dawley rats were divided into 8 groups： empagliflozin group 1 and 2， donafenib group， lenvatinib group， donafenib pretreatment+empagliflozin group， lenvatinib pretreatment + empagliflozin group， empagliflozin pretreatment+donafenib group， and empagliflozin pretreatment+lenvatinib group， with 6 rats in each group. The doses of empagliflozin， donafenib， and lenvatinib were 2.5 mg/kg， 40 mg/kg， and 1.2 mg/kg， respectively. The rats in the empagliflozin group， donafenib group， and lenvatinib group were given a blank solvent by gavage for 7 consecutive days， followed by a single dose of empagliflozin， donafenib， or lenvatinib on day 7 after the administration of the blank solvent； the rats in the pretreatment groups were given the pretreatment drug by gavage for 7 consecutive days， followed by a single dose of drug combination on day 7 after administration of the pretreatment drug. Blood samples were collected at different time points， and plasma was separated to measure the concentration of each drug. A validated ultra-performance liquid chromatography-tandem mass spectrometry method was used to measure the plasma concentrations of donafenib， lenvatinib， and empagliflozin， and a non-compartmental model was used to calculate the main pharmacokinetic parameters of each drug （area under the plasma concentration-time curve ［AUC］， time to peak ［T_max］， peak concentration ［C_max］， and half-life time ［t_1/2］）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. ResultsCompared with the empagliflozin group， the donafenib pretreatment+empagliflozin group had significant increases in the AUC_0-t and AUC_0-∞ of empagliflozin （P=0.011 and 0.008）， while the lenvatinib pretreatment+empagliflozin group had no significant change in the AUC of empagliflozin， with a slightly shorter T_max （P=0.019）. Compared with the donafenib group， the empagliflozin pretreatment+donafenib group had significant increases in the AUC_0-t and AUC_0-∞ of donafenib （P=0.027 and 0.025）， as well as a significant increase in C_max （P=0.015） and significant reductions in CLz/F and Vz/F （P=0.005 and 0.004）； compared with the lenvatinib group， the empagliflozin pretreatment+lenvatinib group had a reduction in the t_1/2 of lenvatinib by approximately 5 hours （P=0.002）， with a trend of reduction in AUC_0-t （P0.05）. ConclusionEmpagliflozin combined with donafenib may alter the pharmacokinetic parameters of both drugs， leading to a significant increase in the exposure levels of both drugs， and efficacy and adverse reactions should be monitored during co-administration. There are no significant changes in the exposure levels of empagliflozin and lenvatinib during co-administration.

This study aimed to introduce a modified Byars staged procedure and investigate its application value in patients with severe hypospadias. We retrospectively analyzed the clinical data of patients with severe hypospadias admitted to the First Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) between October 2012 and October 2022. In total, 31 patients underwent the conventional Byars procedure (conventional group), and 45 patients underwent the modified Byars staged procedure (modified group). Our modified strategy was built upon the standard Byars procedure by incorporating glansplasty during the first stage and employing a Y-shaped flap in conjunction with a glandular tunnel for urethroplasty during the second stage. Notably, there were no statistically significant differences in the preoperative baseline characteristics, duration of surgery, amount of blood loss, or occurrence of postoperative complications, including urethral fistula, stricture and diverticulum, or penile curvature, between the conventional and modified groups. However, there was a significantly lower incidence of coronal sulcus fistula (0 vs 16.1%, P = 0.02) and glans dehiscence (0 vs 12.9%, P = 0.02) in the surgical group than that in the conventional group. In addition, the modified group exhibited a notably greater rate of normotopic urethral opening (100.0% vs 83.9%, P = 0.01) and a higher mean score on the Hypospadias Objective Penile Evaluation (HOPE; mean ± standard error of mean: 8.6 ± 0.2 vs 7.9 ± 0.3, P = 0.02) than did the conventional group. In conclusion, the modified Byars staged procedure significantly reduced the risks of glans dehiscence and coronal sulcus fistula. Consequently, it offers a promising approach for achieving favorable penile esthetics, thereby providing a reliable therapeutic option for severe hypospadias.

OBJECTIVE: To investigate a family with hereditary coagulation factor XI (FXI) deficiency, identify its possible genetic etiology, analyze the bleeding risk of the proband, and provide a blood transfusion regimen. METHODS: The blood samples from the family members were collected, and the coagulation parameters of the proband and her family members were detected. Whole-exome sequencing was performed on the blood samples of the proband to identify gene variants, and validate the variants in the family using Sanger sequencing. Bioinformatics softwares were used to analyze the conservation of amino acid variant sites and the impact of the variations on protein function. The pathogenicity of the variant sites was analyzed according to the genetic variation classification criteria and guidelines of the American College of Medical Genetics and Genomics (ACMG). Thromboelastography (TEG) was used to assess the coagulation function of the family members and evaluate the transfusion regimen and its efficacy in the proband. RESULTS: The activated partial thromboplastin time (APTT) of the proband was significantly prolonged to 96.7 seconds, and FXI activity (FXI: C) and FXI antigen (FXI: Ag) decreased to 1.3% and 1%, respectively, both of which were extremely reduced. The FXI: C of the proband's father was also significantly lower than the normal value. The TEG results showed that the coagulation function of the proband was reduced, while the coagulation function of other family members was normal. The F11 gene of the proband exhibited compound heterozygous variants of c.738G>A (p.Trp246 *) and c.1288G>A (p.Ala430Thr). The proband's father carried a heterozygous missense variant of c.1288G>A (p.Ala430Thr), while her mother, her eldest daughter, and her youngest daughter carried a heterozygous nonsense variant of c.738G>A (p.Trp246 *). According to the ACMG genetic variation classification criteria and guidelines, c.738G>A (p.Trp246 *) is classified as a pathogenic variant (PVS1+PS3-Moderate+PP4), and c.1288G>A (p.Ala430Thr) is classified as a possible pathogenic variant (PS3-Moderate+PM1+PM3_Srong+PP4). p.Trp246 and p.Ala430 are highly conserved across different species. Swiss PdbViewer software analysis showed that p.Ala430Thr variant caused a change in the number of hydrogen bonds in FXI protein, affecting protein function. The following transfusion regimen was determined through TEG evaluation in vitro: 600 ml of fresh frozen plasma (FFP) was administered 24 hours before surgery to prevent bleeding. And there was no significant bleeding during or after the surgery. CONCLUSION The heterozygous nonsense variant ofc.738G>A (p.Trp246 *) and the heterozygous missense variant of c.1288G>A (p.Ala430Thr) in the F11 gene are the pathogenic factors of this hereditary FXI deficiency family.

(+)-Strebloside, a significant bioactive compound isolated from the roots of Streblus asper Lour., demonstrates inhibitory effects against multiple malignancies. However, its specific function and underlying mechanistic pathways in Non-Hodgkin lymphoma (NHL) remain unexplored. This investigation sought to elucidate the role and potential mechanisms of (+)-strebloside-induced NHL cell death. The results demonstrated that (+)-strebloside significantly induced apoptosis and ferroptosis in NHL cells, including those from Raji cell-derived xenograft models. Mechanistic analyses revealed that (+)-strebloside enhanced six-transmembrane epithelial antigen of prostate 3 (STEAP3)-induced ferroptosis in NHL, and STEAP3 inhibition reduced the proliferation-inhibitory effects of (+)-strebloside. Furthermore, (+)-strebloside suppressed NHL proliferation through the mitogen-activated protein kinase (MAPK) pathway, and extracellular signal-regulated kinase (ERK) inhibition diminished the proliferation-inhibitory activity induced by (+)-strebloside. These findings indicate that (+)-strebloside presents promising therapeutic potential for NHL treatment.

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 effect of Chinese medicine He's Yangchao recipe on premature ovarian insufficiency(POI)and its relationship with mitochondrial function of ovarian granulose cells in an animal model.Methods:Thirty-six female C57BL/6J mice were randomly divided into blank control group,model group,low-,medium-and high-dose He's Yangchao recipe treatment group and coenzyme Q10(Q10)treatment group(positive control).The POI model was induced by a single intraperitoneal injection of cyclophosphamide(90 mg/kg).The animals were sacrificed after 21 days.Primary granulose cells were obtained from POI mice and treated with He's Yangchao recipe,ERβ inhibitor PHTPP,and He's Yangchao recipe+PHTPP in vitro for 24 h,respectively.Ovarian histopathological changes were observed by hematoxylin-eosin(HE)staining,ATP levels were detected by luciferase assay,mtDNA copy numbers were detected by quantitative reverse transcriptase-polymerase chain reaction(qRT-PCR),mitochondrial structure changes were observed by transmission electron microscopy,protein and mRNA expression levels of estrogen receptor β(ERβ),peroxisome proliferator-activated receptor γ coactivator 1α(PGC1α),mitochondrial transcription factor A(TFAM),and superoxide dismutase 2(SOD2)were detected by Western blotting and qRT-PCR.Results:The ovarian tissue in model group exhibited few secondary and tertiary follicles,whereas the He's Yangchao recipe groups and Q10 group had abundant secondary and tertiary follicles.Compared with the blank control group,ATP and mtDNA levels in model group decreased(P＜0.01),mitochondrial crista disappeared or abnormal vacuolated structure increased;the protein and mRNA levels of ERβ,PGC1α,TFAM,and SOD2 decreased(all P＜0.01).ATP production increased in granulose cells of high-dose He's Yangchao recipe group and Q10 group;mtDNA copy numbers increased(P＜0.05 or P＜0.01);abnormal mitochondrial structure was reduced;the protein and mRNA expressions of ERβ,PGC1α,TFAM,and SOD2 increased(P＜0.05 or P＜0.01).Compared with the PHTPP intervention group,the proportion of normal mitochondrial structure in the granulose cells of He's Yangchao recipe+PHTPP group was higher;ATP content increased(P＜0.05 or P＜0.01);mtDNA copy numbers increased(P＜0.05 or P＜0.01);the protein and mRNA expression of ERβ,PGC1α,TFAM and SOD2 increased(P＜0.05 or P＜0.01).Conclusions:He's Yangchao recipe can regulate mitochondrial biogenesis through ERβ/PGC1α/TFAM pathway to improve ovarian function in POI mice.

Background::Patients who undergo coronary artery bypass grafting (CABG) are known to be at a significant risk of experiencing long-term adverse events, emphasizing the importance of regular assessments. Evaluating health-related quality of life (HRQoL) serves as a direct method to gauge prognosis. Our objective is to ascertain the prognostic significance of consecutive HRQoL assessments using the Physical Component Summary (PCS) and Mental Component Summary (MCS) derived from the Short-Form 36 (SF-36) health survey in CABG patients.Methods::The study population consisted of 433 patients who underwent isolated elective CABG at Fuwai Hospital between 2012 and 2013. SF-36 assessments were conducted during both the hospitalization period and follow-up. The primary endpoint of the study was all-cause mortality, while the secondary outcome was a composite measure including death, myocardial infarction, stroke, and repeat revascularization. We assessed the relationships between the PCS and MCS at baseline, as well as their changes during the first 6 months after the surgery (referred to as ΔPCS and ΔMCS, respectively), and the observed outcomes.Results::The patients were followed for an average of 6.28 years, during which 35 individuals (35/433, 8.1%) died. After adjusting for clinical variables, it was observed that baseline MCS scores (hazard ratio [HR] for a 1-standard deviation [SD] decrease, 1.57; 95% confidence interval [CI], 1.07–2.30) and ΔMCS (HR for a 1-SD decrease, 1.67; 95% CI, 1.09–2.56) were associated with all-cause mortality. However, baseline PCS scores and ΔPCS did not exhibit a significant relationship with all-cause mortality. Notably, there was a dose-response relationship observed between ΔMCS and the likelihood of all-cause mortality (HRs for the 2nd, 3rd and 4th quartiles compared to the 1st quartile, 0.33, 0.45 and 0.11, respectively).Conclusions::Baseline MCS and changes in MCS were independent predictors for long-term mortality of CABG. Better mental health status and recovery indicated better prognosis.

Abiotic stresses substantially affect the growth and development of plants. Plants have evolved multiple strategies to cope with the environmental stresses, among which transcription factors play an important role in regulating the tolerance to abiotic stresses. Basic leucine zipper transcription factors (bZIP) are one of the largest gene families. The stability and activity of bZIP transcription factors could be regulated by different post-translational modifications (PTMs) in response to various intracellular or extracellular stresses. This paper introduces the structural feature and classification of bZIP transcription factors, followed by summarizing the PTMs of bZIP transcription factors, such as phosphorylation, ubiquitination and small ubiquitin-like modifier (SUMO) modification, in response to abiotic stresses. In addition, future perspectives were prospected, which may facilitate cultivating excellent stress-resistant crop varieties by regulating the PTMs of bZIP transcription factors.
