OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

This paper introduces a real-world cohort research model for community-acquired pneumonia （CAP） based on the Jiangsu Traditional Chinese Medicine （TCM） Dominant Diseases Diagnosis and Treatment Data Platform. Firstly， data cleaning is performed by standardizing diagnosis， symptoms， treatment and imaging， intelligently extracting unstructured information， and cleaning and constructing a standardized database. Secondly， for cohort establishment， CAP patients across the province are screened in accordance with CAP diagnostic criteria to build a high-quality disease-specific cohort. Lastly， in terms of protocol design， the characteristics of TCM research and the CAP disease profile are considered to determine appropriate inclusion and exclusion criteria， estimate sample size， define interventions， outcomes and economic evaluations， providing a reference for real-world TCM research on CAP.

Xuefu zhuyu decoction is a classic formula for promoting blood circulation and resolving blood stasis， characterised by its remarkable ability to treat different diseases with the same approach. Qi stagnation and blood stasis， the primary syndrome for which this formula is indicated， has been found through modern medical research to be intrinsically linked to a wide range of pathophysiological processes， including microcirculatory disorders， abnormalities in hemorheology， inflammatory responses and endothelial dysfunction； which opens up vast scope for the innovative application of traditional formulas. In terms of pharmacological effect and mechanism， the formula exerts a synergistic regulatory effect across multiple key pathological pathways， including the regulation of coagulation function， the maintenance of vascular structure and function， anti-inflammatory and immunomodulatory actions， the mitigation of oxidative stress， and the modulation of programmed cell death （such as pyroptosis and ferroptosis）. This systematically demonstrates its scientific rationale， which is based on integrated regulation through multiple constituents， multiple targets and multiple pathways. In terms of clinical application， the formula has expanded from cardiovascular diseases to multiple disciplines， including gastroenterology， respiratory medicine， urology， neurology， endocrinology， gynaecology and andrology， with evidence-based medical evidence continuing to accumulate. Current research still faces bottlenecks such as a relatively low level of clinical evidence， insufficient systems biology analysis of the mechanisms underlying the compound’s formulation， and a weak correlation between quality control indicators and therapeutic efficacy. Future efforts should focus on conducting multicentre randomised controlled trials for conditions where the formula demonstrates particular efficacy， deepening research into the relationship between integrated pharmacology and spectrum-efficacy relationship， and promoting the precise application and formulation innovation of classical herbal formulas.

This study assessed the role and mechanism of the recombinant Bacillus Calmette-Gue?rin vaccine(rBCG)with c-di-AMP adjuvant in regulating metabolism and immunity in epididymal white adipose(eWAT)in mice.Male C57BL/6 mice were intravenously immunized with BCG and rBCG,and their body weights were monitored.eWAT was isolated from the mice,and the stromal vascular fractions(SVFs)cell number was counted with a hemocytometer.Sections of mouse adipose tissue were prepared,and the size,number,and morphology of eWAT adipocytes and crown-like structure(CLS)formation were compared under a microscope after HE staining.The transcription levels of lipid metabolism-associated factors,cytokines and aging-associated genes in each group were determined with qRT-PCR.The body weights of mice gradually increased after immunization with BCG and rBCG.The proportions of eWAT increased,and the SVFs cell number decreased,in rBCG immunized mice.HE staining indicated that BCG immunization promoted hyperplasia,whereas rBCG immunization promoted hypertrophy of eWAT adipocytes;moreover,both BCG and rBCG immunization induced CLS formation in eWAT.The qRT-PCR results indicated that rBCG immunization inhibited the expression of genes associated with lipolysis and energy expenditure in eWAT.BCG immunization had little effect on cytokine transcription,whereas rBCG significantly induced the transcription of IFN-γ and IL-1Ra,and inhibited that of IL-15 and IL-2,but did not induce the expression of aging-associated genes.Thus,rBCG immunization induced eWAT adipocyte hypertrophy,which was associated with the inhibition of eWAT lipolysis and the regulation of cytokine expression.

Objective:To analyze the clinical features, imaging features and diagnosis and treatment process of a female pelvic epithelioid inflammatory myofibroblastic sarcoma (EIMS) with peritoneal metastasis, so as to improve the clinical understanding and diagnostic ability of the disease and avoid misdiagnosis and missed diagnosis.Methods:The clinical data of a female patient with pelvic EIMS combined with peritoneal metastasis in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed.Results:The triad examination of the patient involved an irregular solid mass in the pelvic cavity about 8.0 cm×9.0 cm in size. Laboratory examination revealed human epididymal protein 4(HE4)154.00 pmol/L. The ultrasonography showed multiple low-echo masses in deep pelvic cavity with unclear boundary and uneven internal echo, and color doppler flow imaging (CDFI) showed abundant internal blood flow signals. Enhanced CT showed uneven and obvious enhancement of the lesion. Pathological examination showed the infiltration of inflammatory cells in the mucous interstitial background. The tumor cells were round and epithelioid, with large nuclei, deep staining and obvious nucleolus. Immunohistochemistry showed anaplastic lymphoma kinase (ALK) positive, and molecular pathology fluorescence in situ hybridization showed ALK gene amplification (positive). Combined with pathological, immunohistochemical and genetic tests, EIMS was diagnosed. Conclusions:EIMS should be considered when there are single or multiple solid or cystic nodules or masses in the pelvic cavity with obvious enhancement, invasive growth and peritoneal implantation metastasis, and the correct diagnosis can be made according to the pathological findings, immunohistochemistry and genetic test results.
