For the treatment of atrial fibrillation,Professor WU Wei innovatively put forward the theory of heart-blood-vessels trinity and the theory of stasis-toxin causing palpitation.It is believed that atrial fibrillation is caused by stasis and toxin,and affects the heart,blood and vessels.The core pathogenesis of atrial fibrillation is due to qi stagnation,blood stasis and toxin.The treatment for atrial fibrillation should be closely based on the pathogenesis,the therapeutic principles of treating from the perspective of stasis and together by removing toxin gradually is advocated.And the therapy of regulating qi,activating blood and removing stasis is also the way to remove toxin.The medication is based on the modified Taoren Honghua Decoction,which is mainly composed of Persicae Semen,Carthami Flos,Chuanxiong Rhizoma,Corydalis Rhizoma,Rehmanniae Radix,Paeoniae Radix Rubra,Salviae Miltiorrhizae Radix et Rhizoma,Jujubae Fructus,Puerariae Lobatae Radix,Nardostachyos Radix et Rhizoma,Ostreae Concha,Poria,and Polygonati Odorati Rhizoma.According to the characteristics of Lingnan climate and atrial fibrillation mostly being easy to affect the emotions,the pungent drugs in the prescription are usually removed,and the specific herbal pair of Puerariae Lobatae Radix-Nardostachyos Radix et Rhizoma is added to remove toxin according to the differentiation of disease.Moreover,for the treatment of atrial fibrillation,Professor WU Wei also adopts traditional Chinese medicine(TCM)external treatment such as foot bath,acupuncture and moxibustion,and physical-breathing exercise as well as health-care methods for comprehensive regulation,relieving the toxin and restoring the original qi.During the treatment atrial fibrillation,Professor WU Wei follows the principle of precise intervention and comprehensive regulation with Chinese medicine,so as to achieve the purpose of eliminating symptoms,restoring sinus rhythm and improving physical constitution.The thoughts of Professor WU Wei for the syndrome differentiation and treatment of atrial fibrillation will provide reference for the treatment of atrial fibrillation with TCM.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To develop a virtual reality (VR) exercise rehabilitation system for home-based patients with spinal cord injury, and test patients' acceptance and experience.Methods:The VR exercise rehabilitation system for home-based patients with spinal cord injury was developed by a multidisciplinary team based on the home rehabilitation needs, evidence, and clinical experience of spinal cord injury patients, and further improved after recommendations from experts and patients. From February to July 2024, convenience sampling was used to select 148 patients with spinal cord injuries admitted to the Department of Spinal Cord and Neurological Function Reconstruction at the China Rehabilitation Research Center. Acceptance Questionnaire was used to investigate patients' acceptance of the system. Thirteen patients with spinal cord injuries were selected for semi-structured interviews to explore the themes of their experiences using VR exercise rehabilitation system for home-based patients with spinal cord injury.Results:A VR exercise rehabilitation system for home-based patients with spinal cord injury was developed, which includes four aspects of personal profile, personal assessment, training selection, and care knowledge. The total acceptance score of this system among 148 patients was (87.69±1.59). Through semi-structured interviews, three themes were identified involving excellent experience, expectation of rehabilitation effects, satisfaction with functionality and hope for continuous system updates.Conclusions:The design of VR exercise rehabilitation system for home-based patients with spinal cord injury is scientifically reasonable, which can further verify the rehabilitation effect of the system.

Objective To investigate the relationship of cerebrospinal fluid and serum levels of soluble interleukin-2 receptor(SIL-2R),endothelial nitric oxide synthase(eNOS),and cluster of differentiation 93(CD93)with the progression and prognosis of viral encephalitis(VE)in children.Methods Prospectively,102 children with VE admitted from January 2021 to January 2024 were selected as the VE group.The patients were divided into a mild subgroup(64 patients)and a severe subgroup(38 patients)according to disease progression.The patients were also divided into a good prognosis subgroup(29 patients)and a poor prognosis subgroup(73 patients)according to prognosis.A control group of 102 children with central nervous system diseases who were examined and found not to have VE during the same period was selected.The factors contributing to the poor prognosis of children with VE and the predictive value of SIL-2R,eNOS,and CD93 in cerebrospinal fluid and serum for the poor prognosis of children with VE were evaluated.Results Cerebrospinal fluid and serum SIL-2R,eNOS,and CD93 levels were significantly increased in the VE group,severe subgroup,and poor prognosis subgroup(P<0.05).Multivariate logistic regression analysis showed that high SIL-2R,eNOS,and CD93 levels in cerebrospinal fluid and serum were risk factors for poor prognosis in children with VE(P<0.05).Receiver operating characteristic curve analysis showed that the combination of cerebrospinal fluid SIL-2R,eNOS,and CD93 was superior to these individual indicators in prediction of poor prognosis in children with VE(P<0.05).Similarly,the combination of serum SIL-2R,eNOS,and CD93 was superior to these individual indicators in prediction of poor prognosis in children with VE(P<0.05).Conclusions The cerebrospinal fluid and serum levels of SIL-2R,eNOS,and CD93 are significantly elevated in children with VE,and they are associated with VE progression and prognosis.

Background: Intrahepatic cholangiocarcinoma (ICC) is a highly desmoplastic tumor with poor prognosis even after curative resection. We investigated the associations between the composition of the ICC stroma and immune cell infiltration and aimed to develop a stromal-immune signature to predict prognosis in surgically treated ICC. Patients and methods: We recruited 359 ICC patients and performed immunohistochemistry to detect α-smooth muscle actin (α-SMA), CD3, CD4, CD8, Foxp3, CD68, and CD66b. Aniline was used to stain collagen deposition. Survival analyses were performed to detect prognostic values of these markers. Recursive partitioning for a discrete-time survival tree was applied to define a stromal-immune signature with distinct prognostic value. We delineated an integrated stromal-immune signature based on immune cell subpopulations and stromal composition to distinguish subgroups with different recurrence-free survival (RFS) and overall survival (OS) time. Results: We defined four major patterns of ICC stroma composition according to the distributions of α-SMA and collagen: dormant (α-SMAlow/collagenhigh), fibrogenic (α-SMAhigh/collagenhigh), inert (α-SMAlow/collagenlow), and fibrolytic (α-SMAhigh/collagenlow). The stroma types were characterized by distinct patterns of infiltration by immune cells. We divided patients into six classes. Class I, characterized by high CD8 expression and dormant stroma, displayed the longest RFS and OS, whereas Class VI, characterized by low CD8 expression and high CD66b expression, displayed the shortest RFS and OS. The integrated stromal-immune signature was consolidated in a validation cohort. Conclusion We developed and validated a stromal-immune signature to predict prognosis in surgically treated ICC. These findings provide new insights into the stromal-immune response to ICC.

Ulcerative colitis(UC) is a recurrent, intractable inflammatory bowel disease. Coptidis Rhizoma and Bovis Calculus, serving as heat-clearing and toxin-removing drugs, have long been used in the treatment of UC. Berberine(BBR) and ursodeoxycholic acid(UDCA), the main active components of Coptidis Rhizoma and Bovis Calculus, respectively, were employed to obtain UDCA-BBR supramolecular nanoparticles by stimulated co-decocting process for enhancing the therapeutic effect on UC. As revealed by the characterization of supramolecular nanoparticles by field emission scanning electron microscopy(FE-SEM) and dynamic light scattering(DLS), the supramolecular nanoparticles were tetrahedral nanoparticles with an average particle size of 180 nm. The molecular structure was described by ultraviolet spectroscopy, fluorescence spectroscopy, infrared spectroscopy, high-resolution mass spectrometry, and hydrogen-nuclear magnetic resonance(H-NMR) spectroscopy. The results showed that the formation of the supramolecular nano-particle was attributed to the mutual electrostatic attraction and hydrophobic interaction between BBR and UDCA. Additionally, supramolecular nanoparticles were also characterized by sustained release and pH sensitivity. The acute UC model was induced by dextran sulfate sodium(DSS) in mice. It was found that supramolecular nanoparticles could effectively improve body mass reduction and colon shortening in mice with UC(P<0.001) and decrease disease activity index(DAI)(P<0.01). There were statistically significant differences between the supramolecular nanoparticles group and the mechanical mixture group(P<0.001, P<0.05). Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6), and the results showed that supramolecular nanoparticles could reduce serum TNF-α and IL-6 levels(P<0.001) and exhibited an obvious difference with the mechanical mixture group(P<0.01, P<0.05). Flow cytometry indicated that supramolecular nanoparticles could reduce the recruitment of neutrophils in the lamina propria of the colon(P<0.05), which was significantly different from the mechanical mixture group(P<0.05). These findings suggested that as compared with the mechanical mixture, the supramolecular nanoparticles could effectively improve the symptoms of acute UC in mice. The study provides a new research idea for the poor absorption of small molecules and the unsatisfactory therapeutic effect of traditional Chinese medicine and lays a foundation for the research on the nano-drug delivery system of traditional Chinese medicine.

Objective To establish a comprehensive evaluation system for the patient monitor clinical application based on real world data(RWD)to provide references for levels of medical institutions to purchase patient monitors.Methods RWD method was used to collect clinical application data of the monitors from 14 medical institutions in Guangxi Zhuang Autonomous Region,and a Chinese brand X(including X1 series for mid-end products and X2 series for high-end products)and a foreign brand Y(including Y1 series for mid-end products and Y2 series for high-end products)with the highest market share were selected to construct a monitor clinical application evaluation system involving in five indicators such as clinical efficacy,applicability,reliability,instrument function and service system.Data processing was carried out with Mantel-Haenszel analysis,propensity score analysis and pairwise comparison method to calculate the clinical application evaluation scores of X and Y brands of monitors.Results In the mid-end products,X series gained advantages over Y series in clinical efficacy,reliability and applicability(P＜0.05),while the differences between the service systems were not statistically signifi-cantly(P＞0.05);in the high-end products,there were no significant differences between the clinical efficacy,applicability,reliability and service systems(P＞0.05).Brand X and Y monitors were equipped with similar basic and advanced functions.Conchision The evaluation system established based on real-world data can be able to effectively evaluate the clinical appli-cation of the monitor,which provides references for clinical application evaluation of medical devices in China.[Chinese Medical Equipment Journal,2023,44(11):71-78]

To review and investigate the diagnosis results of local anesthetics (LA) allergy and improve the understanding of LA allergy in clinician. From March 2017 to February 2022, a total of 24 patients were investigated in Allergy Center of West China Hospital,Sichuan University on suspicion of LA allergy. Clinical data and results of skin tests and drug provocation tests (DPT) with the suspected drugs were retrospectively evaluated. The value of standardized diagnostic protocol in the LA allergy were analyzed. The results showed that 24 patients (3 men/21 women) were included with age range from 20 to 74 years. Three cases (12.5%) were positive in previous LA skin tests and proved to be tolerated through standardized tests. Twenty-one patients were initially diagnosed as "LA allergy" because of adverse reactions after previous use of LA, including 20 cases of immediate-type reaction and 1 case of delayed-type reaction. Three cases were considered LA allergy through standardized diagnosis approaches, including skin tests and DPT. One patient was diagnosed with anaphylaxis caused by chlorhexidine. Of the remaining 17 patients, 7 were considered as psychosomatic reactions (29.1%), 3 of sympathetic nervous system conditions (12.5%), 1 of spontaneous urticaria (4.2%), 2 of vasovagal syncope (8.3%), drug side effects (8.3%), skin irritation (8.3%), respectively. In conclusion, true allergic reactions to LA are rare. Through standardized skin tests and DPT, allergy can be ruled out in the vast majority of patients who complain of "LA allergy". For patients who are highly suspected of LA inducing anaphylaxis, other local anesthetics that can be used as safe alternatives should be determined by diagnostic tests according to future needs.
