To introduce and analyze guideline terminology related to clinical question formulation, evidence retrieval and appraisal, and recommendation development. A systematic search was conducted in guideline development manuals and relevant methodological literature, covering publications up to October 25, 2024. Terminology related to the three aforementioned stages of related to guideline development was extracted from the included literature, standardized, and refined through consensus meetings to finalize a comprehensive terminology list and definitions. A total of 30 guideline development manuals and 15 methodological articles were included, and 23 core terms were identified. It is recommended to develop a standardized and scientifically sound guideline terminology system with unified naming, clear definitions, and alignment with the linguistic environment and usage habits in China. At the same time, it is essential to strengthen terminology training for both guideline developers and users based on this system, in order to deepen their correct understanding and proper application of guideline terminology.

BACKGROUND:
The STAR (Scientific, Transparent, and Applicable Rankings) working group conducts regular evaluations of Chinese guidelines and consensus statements. This study gathered insights from STAR working group members using qualitative interviews.
METHODS:
From March to August 2023, members of the STAR specialist committees were interviewed using semi-structured interview outline. The interviewees were selected through purpose-based sampling. Subject analysis was employed to summarize the findings.
RESULTS:
We conducted interviews with 37 members from 36 committees and summarized the contents into four main themes and 16 specific topics. The value of STAR in enhancing the development and selection of high-quality guidelines in China was commonly mentioned. Challenges identified included the lack of resources and suboptimal organizational structures, collaboration, and evaluation efficiency. Suggestions for the STAR tool included developing extensions for different guideline types, adjusting certain items, and better covering guideline applicability. The promotion of STAR and the consideration of an international committee for global outreach were also highlighted.
CONCLUSION
STAR has exerted a substantial influence on the evaluation of Chinese guidelines, and the insights gained from interviews offer valuable directions for its further enhancement.

Objective To investigate the protective effect and mechanism of heat acclimation(HA)on electromagnetic field(EMF)induced hippocampus neuron injury in mice.Methods Forty healthy BALB/c male mice(18~22 g,7 weeks old)were randomly divided into 4 groups(n=10):Control group(Con),HA group(34℃,30 d),EMF group(2 450 MHz,20 min/d,4 weeks)and HA+EMF group(HA preconditioning+EMF).Sucrose preference test was performed to evaluate sucrose preference levels of mice in each group.Tail suspension test and forced swimming test were utilized to observe the immobility time.Morris water maze test was conducted to determine the learning and memory capabilities.Pathological changes in the hippocampus were observed with HE staining.Immunohistochemical assay for Iba1(marker of microglia),CD68(marker of pro-inflammatory phenotype)and CD206(marker of anti-inflammatory phenotype)were used to detect the number and activation phenotype of microglia in the hippocampus.ELISA was applied to measure the levels of TNF-α,IL-1β,TGF-β and IL-10 in the hippocampus of each group.Western blotting was performed to determine the protein levels of HSP70 in the hippocampus.Results As compared with the Con group,the EMF group showed a decreased preference for sucrose(P<0.05),prolonged immobile time in the tail suspension test(P<0.01)as well as in the forced swimming test(P<0.01),extented escape latency on the 7th day(P<0.01),and a decreased time of crossing the platform(P<0.05).EMF exposure resulted in that the hippocampal neurons were in disordered arrangement,loose structure and irregular morphology,with swollen cytoplasm and condensed nuclei,swollen and more microglial cells in the hippocampus(P<0.01),and enhanced relative fluorescence intensity of CD68(P<0.01),but not in CD206 fluorescence intensity(P=0.885).All these findings suggested that activated microglia predominantly exhibited a pro-inflammatory M1 phenotype during this phase.In the hippocampus,the levels of TNF-α and IL-1β were significantly increased,while the levels of IL-10 and TGF-β were significantly decreased(P<0.01).HA treatment reversed the conditions induced by EMF exposure,including better preference for sucrose(P<0.01),shorten immobile time in tail suspension test(P<0.05)and forced swimming test(P<0.01),less escape latency on the 7th day(P<0.01),and improved hippocampal cell injuries.Compared with the Con group,there were more microglial cells in the hippocampus in the HA+EMF group,with increased relative fluorescence intensity of M2 phenotype marker CD206(P<0.01)and decreased CD68 fluorescence intensity(P<0.01).HA treatment also significantly decreased the expression of TNF-α and IL-1β levels(P<0.01),increased the expression of IL-10 and TGF-β(P<0.01),and elevated the protein level of HSP70(P<0.01)when compared with the EMF group.Conclusion HA may ameliorate EMF-induced hippocampus neurons injury in mice by altering the phenotype of activated microglia and inhibiting inflammatory responses.

The oropouche virus (OROV) poses a threat to pregnant women and fetuses, potentially causing fetal neurological defects and even stillbirth, which has caused global attention. OROV is an arthropod-borne virus belonging to the Orthobunyavirus genus in the Bunyavirales order, primarily transmitted by arthropods and causing oropouche fever. This article reviews the etiological characteristics, epidemiological distribution, clinical symptoms, detection methods, and prevention strategies of OROV. OROV is prevalent in Central and South America, with a sharp increase in cases reported in Brazil in 2024. The virus's symptoms resemble those of several other arthropod-borne viral diseases, which can lead to misdiagnosis. Currently, there are no specific drugs or vaccines available, and treatment is mainly supportive. Culicoides paraensis and Culex quinquefasciatus are among the significant vectors of OROV. Furthermore, the article analyzes the distribution of Culex quinquefasciatus in China, highlights the risk of imported cases, proposes targeted prevention and control strategies, and underscores the significance of international cooperation in disease prevention and control.

Patients with severe fever with thrombocytopenia syndrome (SFTS) often experience coagulation dysfunction. This article reports a case of a critical SFTS patient who developed secondary hemophagocytic lymphohistiocytosis (HLH) and accompanied by significantly prolonged activated partial thromboplastin time (APTT)(111.0 s). APTT mixing test, coagulation factor activity assays, and antiphospholipid antibodies testing excluded coagulation factor deficiencies and classic antiphospholipid syndrome. Combined with elevated endothelial injury markers, it was hypothesized that the prolonged APTT was related to endothelial injury. The patient was treated with dexamethasone, ruxolitinib, and plasma transfusion, the patient′s APTT returned to normal (34.6 s), platelets increased, and levels of ferritin, inflammatory cytokines, and vascular endothelial injury markers decreased. This case suggests that prolonged APTT in SFTS patients may be associated with HLH, cytokine storms, and endothelial injury. Glucocorticoid and Janus kinase inhibitor, by controlling inflammatory responses and reducing endothelial damage, may have potential therapeutic value in correcting coagulation abnormalities.

Objective:Severe fever with thrombocytopenia syndrome (SFTS), caused by the novel bunyavirus, is an emerging infectious disease with a high fatality rate. Co-infections with bacteria or fungi can exacerbate the disease. This study aimed to investigate the characteristics of co-infections in SFTS patients.Methods:A retrospective analysis was conducted on 143 SFTS patients admitted to Qilu Hospital of Shandong University and Juxian People’s Hospital from April 2021 to October 2024.Results:The result showed that 35.7% (51/143) of patients had co-infections, with 85.5% diagnosed within 48 hours of hospitalization. The co-infection group exhibited higher incidences of neurological and respiratory symptoms, lower median platelet counts, and significantly elevated levels of C-reactive protein (CRP), procalcitonin (PCT), blood urea nitrogen (BUN), creatinine (Cr), and ferritin ( P<0.01). Pathogen analysis revealed a predominance of lower respiratory tract Aspergillus infections. Co-infected patients had higher rates of ICU admission (31.4% vs 5.4%), mechanical ventilation (43.1% vs 6.5%), longer hospital stays, higher costs, and lower survival rates (74.5% vs 90.2%). The score within 6 days of disease onset (including age, neutrophil percentage, aspartate transaminase (AST), lactate dehydrogenase (LDH), and BUN) was a significant risk factor for co-infection. A predictive model combining CRP, BUN, and the composite score demonstrated superior performance (AUC=0.851). Conclusions:This study provides critical evidence for early diagnosis and identification of high-risk populations for co-infections in SFTS patients.
