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.

Diabetic nephropathy（DN） is a common and severe microvascular complication of diabetes. In recent years， the classical herbal formula Shenqi dihuang decoction has demonstrated unique advantages in the clinical treatment of DN. This article conducts a systematic review of the mechanisms of action and clinical applications of Shenqi dihuang decoction in the treatment of DN. It reveals that the mechanism by which this formula improves DN involves multi-target synergistic regulation. For instance, Shenqi dihuang decoction exerts multiple pharmacological effects by regulating signaling pathways including phosphatidy linostiol 3-kinase/protein kinase B， AMP-activated protein kinase/silent information regulator 1/forkhead box O1， and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 pathways.These effects include regulating glucose and lipid metabolism， inhibiting oxidative stress， reducing inflammation， improving insulin resistance， modulating cell death （apoptosis/autophagy/ferroptosis/pyroptosis）， and preventing renal fibrosis. Existing clinical studies indicate that Shenqi dihuang decoction and its modified formulas， alone or in combination with other therapeutic methods， can significantly improve glucose and lipid metabolism， reduce proteinuria， and delay renal function decline in patients with DN. These effects are superior to those of Western medicines such as irbesartan， valsartan， and empagliflozin， and the treatment demonstrates good safety. Future research should leverage systems biology and artificial intelligence technologies to further elucidate the integrated mechanisms in the treatment of DN by Shenqi dihuang decoction， thereby advancing the precision and standardization of its clinical application.

To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen， kidney essence deficiency， liver constraint transforming into fire， and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen （TE 21）， Tinggong （SI 19）， Tinghui （GB 2）， Shenmai （BL 62） to regulate qi and blood， and supporting with Baihui （GV 20）， Yintang （EX-HN 3）， Taichong （LR 3）， and Yanglingquan （GB 34） to soothe the liver， resolve constraint， and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction （益气聪明汤） and Tongqi Powder （通气散）， and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder （温清散） to navel moxibustion.

Based on the theory of "three regions and sanjiao" in traditional Chinese medicine (TCM), the acupuncture-moxibustion differentiation and treatment system is explored and constructed for spasm syndrome, so as to provide a clearer guiding framework for TCM treatment of spasm syndrome. This disorder is caused essentially by the invasion of pathogenic wind, and located in brain marrow. The key regions of illness cover five zang organs and five tissues, and the core pathogenesis is associated with wind disturbance in brain marrow. In differentiation, spasm syndrome refers to overall transmission (from the upper to the lower) and local transmission (from exterior to interior). This disorder can be classified into sanjiao spasm (heart-lung spasm of the upper jiao, liver-spleen spasm of the middle jiao, and liver-kidney spasm of the lower jiao) and three-region spasm (skin-vessel spasm of the upper region, tendon-muscle spasm of the middle region, and tendon-bone spasm of the lower region). Based on "three regions and sanjiao" theory of acupuncture and moxibustion, 7 "expelling-wind" points can be selected in terms of the etiology of this disease. Baihui (GV20)-toward-Taiyang (EX-HN5) needling is applied to regulate the brain marrow, focusing on the core location of illness; and regarding the key location of illness, the combination of back-shu and front-mu points and that of jing-well and xing-spring points are adopted to regulate five zang organs. The five needling techniques (half needling, leopard-spot needling, joint needling, Hegu needling and shu needling) are used to regulate five tissues.

Early-onset colorectal cancer (EOCRC) shows a different epidemiological trend compared to later-onset colorectal cancer, with its incidence rising in most regions and countries worldwide. However, the reasons behind this trend remain unclear. The etiology of EOCRC is complex and could involve both genetic and environmental factors. Apart from Lynch syndrome and Familial Adenomatous Polyposis, sporadic EOCRC exhibits a broad spectrum of pathogenic germline mutations, genetic polymorphisms, methylation changes, and chromosomal instability. Early-life exposures and environmental risk factors, including lifestyle and dietary risk factors, have been found to be associated with EOCRC risk. Meanwhile, specific chronic diseases, such as inflammatory bowel disease, diabetes, and metabolic syndrome, have been associated with EOCRC. Interactions between genetic and environmental risk factors in EOCRC have also been explored. Here we present findings from a narrative review of epidemiological studies on the assessment of early-life exposures, of EOCRC-specific environmental factors, and their interactions with susceptible loci. We also present results from EOCRC-specific genome-wide association studies that could be used to perform Mendelian randomization analyses to ascertain potential causal links between environmental factors and EOCRC.

Objective:To investigate the clinical characteristics of residual dizziness（RD） after repositioning in patients with benign paroxysmal positional vertigo（BPPV）, identify its potential risk factors, and develop a predictive risk model. Methods:A total of 137 patients diagnosed with BPPV at the First Affiliated Hospital of Xi'an Jiaotong University between January 2023 and June 2023 were enrolled. Based on the presence or absence of subjective discomfort within 3 months after successful repositioning, patients were divided into the non-RD group（NRD, n=93） and the RD group（n=44）. Differences in demographic characteristics, comorbidities, and disease-related features were compared between groups. Multivariate logistic regression analysis was used to identify independent risk factors for RD, and a nomogram was constructed based on these factors. The predictive performance of the model was assessed using the area under the curve（AUC）. Results:The RD group showed significantly higher values in body mass index, prevalence of diabetes and motion sickness history, dizziness duration before repositioning, history of repositioning at external hospitals, number of treatments, and recurrence（all P<0.001）. Multivariate logistic regression revealed that diabetes（adjusted OR=8.73, P=0.039）, motion sickness history（adjusted OR=23.08, P<0.001）, dizziness duration ≥30 days before repositioning（adjusted OR=15.16, P<0.001）, and recurrence（adjusted OR=15.72, P=0.001） were independent risk factors for RD. The nomogram model based on these variables demonstrated good predictive ability, with an AUC of 0.804（95%CI 0.684-0.924）. Conclusion:Diabetes, motion sickness history, dizziness duration ≥30 days, and recurrence are independent risk factors for RD after repositioning in patients with BPPV. The nomogram model based on these variables shows good predictive performance, with recurrence having the highest predictive value. This model can aid in early identification of high-risk patients and guide individualized intervention strategies.

The study explores the thermal dose of experimental animals exposed in electromagnetic field.The simulation environment containing electromagnetic and thermal doses is established based on the bioheat equation and the three-dimensional rat model,and the effects of specific absorption rate,metabolic rate and boundary condition on temperature distribution and variation are assessed.The result shows that the core temperature rises with increasing whole body average specific absorption rate(WBASAR).At WBASAR of 4 W/kg,the midbrain and testes have higher specific absorption rates due to the skin effect,resulting in a more significant temperature rise in organ tissues than in the core;and at WBASAR of 0.4 W/kg,the temperature variation of the shallow organs caused by the sudden changes of metabolic and external environment reaches 1℃,which is much larger than that of the core.The experiment demonstrates target organs such as the head and testicles as critical subjects in thermal dose assessment.The experimental conditions should be regulated to reduce the effects of metabolic rate and boundary condition on thermal dose.The study has guiding significance for bioelectromagnetic experimental design and effect evaluation on thermal dose.

Objective To analyze the bioelectromagnetic dose of human blood-brain barrier opening induced by electromagnetic pulse.Methods A typical exposure platform was used to establish an environment for human brain dosimetric study.The bioelectromagnetic dose was evaluated with electromagnetic simulation method using a 3D digital human model.Results The electric field at the centre of the head reached a peak of 1.49 kV/m,and there was a decrease of 41.6 dB from the excitation field.The maximum electric field amplitude on the surface of the nose tip was 1795 kV/m.The head had an average absorption rate of 4.16×10-8 J/kg under one pulse,while under extreme conditions with a repetition frequency of 1000 s-1,the average specific absorption rate of the head was 4.16×10-5 W/kg.Conclusion Local high-intensity electric fields pose significant safety risks in clinical application,and it is necessary to study the means of inhibiting local high-intensity electric field in combination with the dose-effect relationship of blood-brain barrier opening.The human brain bioelectromagnetic doses provided by the study can be used to evaluate the clinical efficacy.
