The European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) have recently updated and published the 2024 ESC guidelines for the management of atrial fibrillation. Based on the latest evidences, the guidelines have been updated in many aspects, such as diagnostic criteria for atrial fibrillation, AF-CARE treatment principles, comorbidities and risk factor management. In particular, there are significant changes in the recommendations for surgical management of atrial fibrillation in the guidelines. Therefore, this paper aims to interpret the content updates of the guidelines in AF-CARE treatment principles, diagnostic criteria and surgical treatment of atrial fibrillation, especially highlighting the updates and new suggestions about surgical treatment of atrial fibrillation.

In the era of big data, neuroimaging and algorithmic analyses have propelled brain science research and brain mapping. Acupuncture, widely recognized as an effective surface stimulation therapy, has demonstrated therapeutic efficacy for various brain conditions such as stroke and depression. However, the mechanisms linking acupuncture to brain function and its modulatory effects on brain activity require systematic exploration. Additionally, there is an urgent need to scientifically reinterpret traditional meridian theory and enhance its clinical applicability. Therefore, we propose the initiative of constructing a "brain mapping atlas of meridian, collateral and body surface stimulation" to explore the patterns linking the therapeutic effects of stimulating the twelve meridians, eight extraordinary vessels, divergent channels, collateral channels, sinew channels, and skin regions to brain function. This initiative aims to provide a scientific interpretation of traditional Chinese medicine meridian theory and enhance its practical applicability. This paper begins by reviewing the current state of brain mapping. It then summarizes existing research on the relationship between acupuncture and the brain, highlighting the necessity of constructing this atlas. The paper further analyzes the methodologies and technical challenges involved. Finally, the potential applications of the brain mapping atlas of meridian, collateral and body surface stimulation, and its main significance in advancing traditional meridian theory to keep pace with the times are prospected.

OBJECTIVE: To observe the efficacy of the Tongnao Huoluo Liyan (unblocking brain, activating collaterals and relaxing throat) acupuncture combined with rehabilitation training for post-stroke dysphagia (PSD). METHODS: A total of 92 PSD patients were randomly assigned to an observation group (46 cases, 1 case was discontinued) and a control group (46 cases, 1 case was discontinued, 1 case dropped out). The patients in the control group received rehabilitation training, including low-frequency neuromuscular electrical stimulation for swallowing, lip and tongue movement training, and oral sensory function training, once daily, five times per week, for four weeks. The patients in the observation group received the Tongnao Huoluo Liyan acupuncture method in addition to the same rehabilitation training. Acupoints included Lianquan (CV23), bilateral Jia Lianquan, Jinjin (EX-HN12), Yuye (EX-HN13), Baihui (GV20), Shuigou (GV26), and bilateral Neiguan (PC6), once daily, five times per week, for four weeks. Before and after treatment, Kubota water stvallowing test grading, standardized swallowing assessment (SSA) scores, Fujishima Ichiro swallowing efficacy scores, and swallowing quality of life questionnaire (SWAL-QOL) scores were assessed in both groups. Surface electromyography (sEMG) was used to evaluate the average amplitude (AEMG) and mean swallowing time of the suprahyoid and infrahyoid muscle groups. RESULTS: After treatment, the proportion of patients classified as Grade Ⅰ or Ⅱ in the Kubota water stvallowing test was increased in both groups (P<0.05), with better results in the observation group compared to the control group (P<0.05). Compare before treatment, SSA scores were decreased in both groups after treatment (P<0.05), with lower scores in the observation group than in the control group (P<0.05). Compare before treatment, Fujishima Ichiro swallowing efficacy scores and SWAL-QOL scores were improved in both groups after treatment (P<0.05), with significantly higher scores in the observation group than those in the control group (P<0.05). Compare before treatment, AEMG values of the Submental musckes and infrahyoid muscles groups were increased (P<0.05), and mean swallowing time was decreased (P<0.05) in both groups after treatment. The observation group showed greater increases in AEMG values and shorter mean swallowing times compared to the control group (P<0.05). The total effective rate was 97.8% (44/45) in the observation group, higher than 84.1% (37/44) in the control group (P<0.05). CONCLUSION The Tongnao Huoluo Liyan acupuncture combined with rehabilitation training could enhance the contraction function in swallowing-related muscle groups, facilitate hyoid and laryngeal elevation, restore swallowing function, and improve patients' quality of life. This combined treatment approach is superior to rehabilitation training alone.

Objective: To assess the association between the metabolic score for insulin resistance index (METS-IR) and overactive bladder (OAB) in the US population，so as to explore the potential of METS-IR as a predictive tool for OAB risk and to provide insights for early screening and intervention strategies. Methods: Based on the data from the National Health and Nutrition Examination Survey (NHANES) 2005-2018，a cross-sectional design was employed，and multivariate logistic regression models were used to analyze the association between METS-IR and OAB. METS-IR was analyzed both as a continuous variable and categorized into quartiles. To further validate the association between METS-IR and OAB across diverse populations，subgroup analyses were conducted in participants stratified by clinical characteristics. Smooth curve fitting was employed to test the linearity of the METS-IR-OAB relationship. Results: Elevated METS-IR was associated with an increased risk of OAB (P<0.001)，and this positive correlation remained stable when METS-IR was categorized into quartiles (P<0.001). Subgroup analyses revealed that the association between METS-IR and OAB was more pronounced in females，participants younger than 55 years，and non-diabetic individuals (P<0.05). Furthermore，smooth curve fitting confirmed a linear positive correlation between METS-IR and OAB，with this linear relationship observed in both diabetic and non-diabetic groups. Conclusion: This study，based on the NHANES 2005-2018 database，found a linear positive correlation between METS-IR and OAB.

OBJECTIVE To evaluate the cost-effectiveness of dapagliflozin and empagliflozin in the treatment of type 2 diabetic kidney disease from the perspective of healthcare system in China. METHODS Based on the data from the two multicenter clinical trials， DECLARE-TIMI 58 and EMPA-REG OUTCOME， a Markov model was constructed according to the urinary albumin-to-creatinine ratio （UACR） of the patients with type 2 diabetic kidney disease with a cycle of 1 year， simulating until 99% of patients died. The model outputs were total costs and quality-adjusted life year （QALY）. The cost-effectiveness of the two treatment regimens was assessed by comparing their incremental cost-effectiveness ratio （ICER） and the willingness-to-pay threshold （WTP，set at three times China’s 2023 per capita gross domestic product， i.e.， 268 074 yuan/QALY）. Additionally， oneway sensitivity analysis and probabilistic sensitivity analysis were performed to test the robustness of the base analysis results. RESULTS Compared with dapagliflozin， the ICER for empagliflozin regimen was 44 334.82 yuan/QALY， which was below the WTP ， indicating its cost-effectiveness. The results of the oneway sensitivity analysis indicated that the incidence of non-fatal myocardial infarction in both groups and the utility values associated with the microalbuminuria state had the most significant impact on the outcomes， but did not change the base-case conclusion. The probabilistic sensitivity analysis indicated that the results of the base-case analysis were robust. CONCLUSIONS With a WTP of three times China’s per capita gross domestic product in 2023， empagliflozin is more cost-effective than dapagliflozin in treating type 2 diabetic kidney disease.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

Objective To establish an electrical field(EF)stimulation model for Schwann cells(SCs),and to provide a basis for exploring the mechanisms of EF stimulation in promoting proliferation,migration and epithelial-to-mesenchymal transition of SCs.Methods A YC-3 bipolar programmable electrical stimulator and an electrotaxis chamber were used to construct an EF stimulation system to stimulate SCs.In the study,SCs were divided into control group(Ctrl)receiving no EF stimulation and EF group stimulated by continuous constant-voltage EF(100 mV/mm,3 h).The effects of EF stimulation on the proliferation and migration of SCs were analyzed using CCK-8 assay,and wound healing assay+Transwell assay,separately;and its effect on SCs adhesion was observed by analyzing the expressions of E-cadherin and N-cadherin using Western Blot.Results The CCK-8 assay results suggested that the absorbance at 450 nm was significantly higher in EF group than in Ctrl group(P<0.05).The results of wound healing assay+Transwell assay revealed that EF group had higher cell migration efficiency than Ctrl group(P<0.05).Western Blot results showed decreased E-cadherin expression and increased N-cadherin expression in EF group as compared with Ctrl group(P<0.05).Conclusion The improved EF stimulation system for SCs is operable.EF stimulation can promote the proliferation and migration of SCs.The decreased E-cadherin expression and increased N-cadherin expression may be related to the occurrence of epithelial-to-mesenchymal transition in SCs after EF stimulation.

Traditional Chinese medicine of Polygonum cuspidatum has been utilized in China for thousands of years. Its primary active compound, polydatin, exhibits a variety of pharmacological effects including the regulation of glucose and lipid metabolism, suppression of cough and asthma, as well as antibacterial and anti-inflammatory properties. However, conventional methods for polydatin production are inadequate to satisfy the market demand. This study aims to explore the green and efficient preparation of polydatin. With resveratrol as the substrate, we efficiently synthesized polydatin by using the triple mutant IGW (Y14I/I62G/M315W) of the glycosyltransferase UGT_BS based on a strategy of two-enzyme coupled with one-pot and realized the recycling of uridine diphosphate-glucose (UDPG). The conditions of the two-enzyme reaction were optimized. Under the conditions of 35 ℃, pH 8.0, IGW: AtSuSy1 activity ratio of 3:4, dimethyl sulfoxide (DMSO) volume fraction of 5%, uridine diphosphate (UDP) concentration of 0.10 mmol/L, and sucrose concentration of 0.6 mol/L, the conversion of 2 mmol/L resveratrol reached 80.6% within 1 h, and the proportion of polydatin was over 90%. This study achieved the recycling of UDPG via a two-enzyme coupling system and shortened the reaction time. At the same time, the fed-batch strategy was adopted, and the yield of polydatin reached 6.28 g/L after 24 h in the one-pot coupling reaction, which provided a new strategy for green and efficient preparation of polydatin.
