To interpret the evidence-to-decision (EtD) framework and to illustrate its application in traditional Chinese medicine (TCM) guideline development using the example of the Pharmacovigilance Guideline of Chinese Patent Medicine, thereby providing methodological references for TCM guideline standardization. Based on the core three stages of the EtD framework (formulating the question, making an assessment of the evidence, and drawing conclusions), critical decision points and evaluation evidence within the evidence-translation process were systematically addressed, aligning with the purpose, scope, and key questions of the guideline. Qualitative research methods, such as the nominal group technique, were employed to formulate recommendations. The analysis was conducted based on the EtD framework. During question formulation, the specific characteristics and practical needs of pharmacovigilance for Chinese patent medicines were clarified, focusing on the core objective of safety assurance throughout the product lifecycle. In the evidence assessment, multi-source evidence was integrated, including policy documents, literature research, and expert consensus, completing the evidence evaluation. Finally, in recommendation-forming, dispersed research evidence and expert experience were synthesized into consensus, culminating in the guideline's completion through solicitation of opinions and peer review. The EtD framework provides a structured tool for evidence-to-decision translation in TCM guideline development, effectively enhancing the transparency and scientific rigor of the process. Therefore, it is recommended that TCM guideline development adopt the EtD framework to improve the evidence-to-decision process with TCM characteristics.

To standardize the clinical application of oral Chinese patent medicines (CPMs), and address the safety issues arising from their dosage form characteristics, irrational clinical use, and the lack of targeted pharmacovigilance systems, the China Association of Chinese Medicine organized the formulation and release of Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines, aiming to inform the safe clinical use of oral CPMs and related pharmacovigilance work. According to the principles of GB/T1.1—2020 and the Drug Administration Law of the People's Republic of China (2019 revision), the Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences, led a drafting group comprising 18 institutions. After multiple rounds of expert interviews, literature retrieval, evidence screening, and extensive solicitation of opinions, the Guidelines were registered internationally. Systematic standardization focused on safety monitoring, risk identification, assessment, control, and other aspects. The Guidelines clarified the characteristics of oral CPMs in terms of safety monitoring, known risks, and potential risks, compared to non-oral CPMs. Then, risk control measures were proposed, including medication in special populations and irrational medication. As a special guideline for pharmacovigilance in the clinical application of oral CPMs, the Guidelines systematically construct a technical system in line with the characteristics of traditional Chinese medicine (TCM), which is essential for improving the clinical safety management of oral CPMs and provides an important reference for medical institutions, pharmaceutical manufacturers, and regulatory authorities.

Objective:To investigate the role of Fem-1 homolog C(FEM1C)in breast cancer progression and elucidate its underlying regulat-ory mechanism.Methods:The expression of FEM1C in breast cancer tissues and cells were detected with qPCR.The binding of FEM1C to ELAVL1 protein was predicted with an online database and validated by CoIP analysis;and the binding of ELAVL1 protein to OPA1 mRNA was predicted by using the starBase database and validated by RIP analysis.Next,breast cancer cell MDA-MB-231 was transfected with FEM1C shRNA(sh-FEM1C)or overexpression vector(FEM1C)or/and ELAVL1 overexpression vector(ELAVL1)or/and OPA1 overexpression vector(OPA1),or treated with 100 μM Mdivi-1,an DRP1 inhibitor,or MYLS22,an OPA1 inhibitor.Finally,nude mice were injected with sh-FEM1C lentiviral vectors to construct xenograft tumor models,and tumor growth was monitored.Results:The expression of FEM1C was upregu-lated in breast cancer tissues(P<0.01).Silencing FEM1C inhibited the proliferation,induced apoptosis,promoted the expression of auto-phagy protein LC3 Ⅱ/Ⅰ,inhibited p62 protein expression,upregulated the protein level of PINK1 in mitochondrial,promoted the expres-sion of mitochondrial fission proteins DRP1 and MIEF2,and inhibited the expression of fusion proteins OPA1 and MFN1 in MDA-MB-231 cells(P<0.01).Mdivi-1 treatment inhibited DRP1 expression(P<0.01),but had no effect on cell viability(P>0.05);MYLS22 treatment inhibited OPA1 expression and counteracted the effect of FEM1C overexpression on MDA-MB-231 cells(P<0.01).Mechanistic studies revealed that FEM1C binds to ELAVL1 protein and promotes its expression(P<0.01);ELAVL1 protein stabilizes OPA1 mRNA by binding to it and upregu-lates OPA1 protein levels(P<0.01).Overexpression of OPA1 reversed the effect of FEM1C silencing on MDA-MB-231 cells(P<0.01).In vivo results showed that knockdown of FEM1C inhibited tumor growth in vivo(P<0.01).Conclusions:FEM1C promotes the stability of OPA1 mRNA by upregulation of ELAVL1 protein to promote mitochondrial fusion and inhibit autophagy,thereby promoting breast cancer progression.

Objective To investigate the changes and diagnostic value of serum hypoxia inducible factor 1 subunit alpha(HIF-1α)and Toll-like receptor 4(TLR4)levels in patients with chronic obstructive pulmonary disease(COPD)complicated with pulmonary Aspergillosis infection.Methods A total of 240 COPD patients who visited Xi'an Qinhuang Hospital(hereinafter referred to as the hospital)from December 2020 to Decem-ber 2023 were selected as the study subjects in the study,and another 218 volunteers who underwent physical examinations at the hospital were selected as the control group.The COPD patients were separated into an in-fected group(124 cases)and an uninfected group(116 cases)based on whether they had pulmonary Aspergil-losis infection.Enzyme-linked immunosorbent assay was applied to detect the levels of HIF-1α and TLR4 in patients.Fully automated biochemical analyzer was applied to detect lactate dehydrogenase(LDH)and albu-min(ALB)levels.Multivariate Logistic regression was applied to analyze the influencing factors of infection in COPD patients.Pearson correlation was applied to analyze the correlation between HIF-1α and TLR4 levels in the infected group.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic val-ue of HIF-1α and TLR4 levels for the occurrence of infection in COPD patients.Results Compared with the control group,the COPD group showed an increase in HIF-1α and TLR4 levels(P<0.05).Compared with the uninfected group,the proportion of dyspnea,antibiotics>3 types,the duration of antibiotic use ≥ 14 days,mechanical ventilation procedures,the longer glucocorticosteroid(GC)use time,and levels of LDH,HIF-1α,TLR4 in the infected group were higher(P<0.05),while the level of ALB was lower(P<0.05).The types of antibiotics>3 types,the duration of antibiotic use ≥ 14 days,the duration of GC use,and elevat-ed levels of LDH,HIF-1α,and TLR4 were independent risk factors for infection in COPD patients(P<0.05),while elevated level of ALB was an independent protective factor for infection in COPD patients(P<0.05).The levels of HIF-1α and TLR4 in the infected group were positively correlated(r=0.453,P<0.001).The area under the curve(AUC)of HIF-1α and TLR4 in diagnosing infection in COPD patients alone was 0.816 and 0.813,and the AUC of their combined diagnosis was 0.930,which was better than their indi-vidual diagnoses(Zcombination-HIF-1α=4.923,Z combination-TLR4=5.192,P<0.001,P<0.001).Conclusion The levels of HIF-1α and TLR4 increase in COPD patients,and further increase after infection with pulmonary Aspergil-lus.They are independent risk factors for infection in patients,and the two are positively correlated.The combined di-agnosis of pulmonary aspergillosis has certain value and provides a theoretical basis for clinical diagnosis.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To compare the degranulation levels of basophils in peripheral blood mononuclear cell (PBMC) and granulocyte populations between healthy subjects and patients with sepsis, and to explore the underlying mechanisms. Additionally, plasma cytokine levels were measured in these volunteers.Methods:Peripheral blood samples were collected from both healthy individuals and sepsis patients. The degranulation level of basophils in sepsis patients and its potential mechanisms were examined. Plasma levels of IL-1β, IL-9, and IL-10 were detected, and Pearson correlation analysis was performed to assess the relationship between degranulated basophils in the granulocyte population and IL-9 levels.Results:Compared with healthy subjects, sepsis patients showed a reduction in basophil percentages within PBMC and granulocyte populations by 94.8% and 37.9%, respectively ( Z = -6.441, P < 0.05; Z = -2.681, P < 0.05). In contrast, both the proportion and number of degranulated basophils in the granulocyte population were increased (both P < 0.05). Plasma levels of IL-1β, IL-9, and IL-10 were significantly elevated in sepsis patients--by 80.6%, 36.7%, and 11.9-fold, respectively ( Z = -4.258, P < 0.05; Z = -3.606, P < 0.05; Z = -4.814, P < 0.05). Moreover, plasma IL-9 levels were highly correlated with both the percentage and count of degranulated basophils in the granulocyte population (both P < 0.05). GO and KEGG enrichment analyses revealed cytological changes and potential mechanisms involving basophils in the PBMC of sepsis patients. Conclusions:The decreased total count of basophils in sepsis patients may elevate the risk of secondary infection. Degranulated basophils in the granulocyte population may contribute to excessive inflammatory responses through IL-9 secretion.

Objective:To analyze the clinical efficacy and safety of carglumic acid in the treatment of neonatal hyperammonemia caused by organic acidemia.Methods:A case summary was made.Six cases of neonatal hyperammonemia caused by organic acidemia treated at the Neonatal Intensive Care Unit of Henan Children′s Hospital from March to September in 2024 were included.They received comprehensive ammonia-lowering treatment in combination with oral carglumic acid dispersible tablets.The clinical data of the children were collected and analyzed retrospectively.Changes in blood ammonia levels, blood gas parameters, and complete blood count before and after treatment with carglumic acid were analyzed using the Wilcoxon test.The incidence of adverse reactions and clinical regression during the treatment with carglumic acid was observed.Results:There were 2 females and 4 males in the 6 patients included.Four children suffered from isolated methylmalonic acidemia caused by MUT gene mutations, and the other 2 had propionic acidemia.The clinical manifestations were poor breastfeeding in 6 cases, vomiting in 2 cases, poor response in 6 cases, weight loss in 6 cases, and convulsions in 3 cases.Acute metabolic decompensation abnormalities were presented in all children, such as metabolic acidosis, hyperammonemia, leukopenia and thrombocytopenia.The first dose of carglumic acid was 62-255 mg/kg, the second dose was 75-172 mg/kg.The blood ammonia level decreased from 411.7 (339.7, 623.8) μmol/L before treatment to 108.1 (35.5, 229.1) μmol/L after 48 hours of treatment, showing a statistically significant reduction ( Z=2.20, P<0.05).Three cases with a blood ammonia level higher than 400 μmol/L, it was effectively reduced after treatment with carglumic acid.Two cases did not undergo hemodialysis or peritoneal dialysis.One case underwent hemodialysis but died after withdrawing the treatment.After administration of carglumic acid, metabolic acidosis was corrected in all children, and 2 patients ultimately died after discontinuing the treatment.No causal relationship was identified between adverse events and carglumic acid treatment.The examinations at discharge and during the follow-up period (2-7 months) showed that most laboratory abnormalities (including leukopenia, anemia, thrombocytopenia, hyperlactatemia, hyponatremia, hyperkalemia, elevated myocardial enzymes, and hyperbilirubinemia) returned to normal. Conclusions:Carglumic acid can effectively reduce neonatal hyperammonemia caused by organic academia, improve metabolic disorders, and reduce the need for blood purification or peritoneal dialysis, with good safety.

ObjectiveTo investigate the anti-Alzheimer's disease (AD) effect of Dipsacus asper(DA) in the Caenorhabditis elegans model, and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α (PPARα)/transcription factor EB (TFEB) pathway. MethodsFirst, transgenic AD C. elegans individuals were assigned into the blank control, model, positive control (WY14643, 20 µmol·L-1), and low-, medium-, and high-dose (100, 200, and 400 mg·L-1, respectively) DA groups. The amyloid β-42 (Aβ42) formation in the muscle cells, the paralysis time, and the deposition of amyloid β-protein (Aβ) in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ, LC3I, LAMP2, and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα, and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain (LBD). ResultsCompared with the model group, the positive control group and 200 and 400 mg·L-1 DA groups showed prolonged paralysis time (P<0.05), and all the treatment groups showed decreased Aβ deposition in the head (P<0.01). DA within the concentration range of 50-500 mg·L-1 did not affect the viability of BV2 cells. In addition, DA enhanced the autophagy flux (P<0.05), up-regulated the mRNA levels of beclin1, Atg5, LAMP2, and CLN2 (P<0.05, P<0.01), promoted the nuclear translocation of TFEB (P<0.05), increased LAMP2 expression and autophagy flux (P<0.05, P<0.01), and enhanced the transcriptional activities of PPARα and TFEB (P<0.01). The positive control group and 200 and 400 mg·L-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus (P<0.01). UPLC-MS detected nine known compounds of DA, from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.
