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.

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.

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.

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.

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 explore the clinical application value of deep learning image reconstruction(DLIR)-based technique for radiation dose reduction with different noise index(NI)in CT-guided percutaneous transthoracic needle biopsy(PTNB).Methods Thirty-two patients undergoing PTNB were selected,and three sets of CT images with NI of 15,30,and 45 sequentially were obtained after adjusting the puncture needle using the scanning parameters of a small range(40 mm),tube voltage 100 kV,and automatic tube cur-rent modulation(ATCM).Group A was 50％weight of adaptive statistical iterative reconstruction-Veo(ASIR-V)scanned with NI 15,and group B and C were the DLIR-high reconstructed images with NI 30 and NI 45 respectively.The CT value and standard devia-tion(SD)value of paraspinal muscles,subcutaneous fat,and arterial vessels were measured at the puncture center point and its upper and lower 10 mm sclices,respectively,and the signal-to-noise ratio(SNR)and the contrast-to-noise ratio(CNR)were also calculated.Then the images were subjectively scored by two physicians,meanwhile the effective dose(ED)among the three groups was com-pared.Results According to the subjective evaluation,the image quality of group A,B,and C all met the clinical requirement for puncture.The SD and SNR of the images in group B were better than those in groups A and C.The SD and SNR of paraspinal mus-cles and sudcutaneous fat were significantly different between groups A and B,and between groups B and C(P＜0.05),however those of paraspinal muscles and subcutaneous fat between groups A and C were not significant.The differences in ED among the three groups were all statistically significant(P＜0.05).Compared with group A,the ED in groups B and C were reduced by 82.86％and 93.90％respectively,and the ED in group C was reduced by 64.44％compared with group B.Conclusion Increasing the NI combined with the DLIR technique can significantly reduce the radi-ation dose during CT-guided PTNB.

Objective:To investigate the feasibility and clinical effects of the application of augmented reality (AR) navigation on assisted design of the chimeric twin-paddled anterolateral thigh perforator flap (ALTPF) in reconstruction of soft tissue defects in extremities.Methods:From June 2017 to June 2023, 8 patients with soft tissue defects in extremities received reconstruction of chimeric twin-paddled ALTPF designed with the assistance of AR navigation in Department of Hand & Foot Microsurgery Orthopaedics, Guigang City People’s Hospital. All of them were traffic accidents or machine injuries, with 3 cases of calf, 2 cases of ankle, 1 case of foot, and 2 cases of hand defects. All the wounds were wide or irregular (defect sized 14 cm×14 cm-25 cm×13 cm). The images of bilateral thighs were acquired by CT angiography preoperatively. The dominant side and dominant perforators were selected. Three dimensional reconstruction was performed by Mimics software. AR technology was applied to guide the design and harvest of the chimeric twin-paddled ALTPF. Flap area was 15 cm × 16 cm to 26 cm × 14 cm. The donor site was sutured directly. Follow-up with outpatient visits or WeChat images and videos at 1, 3, 6 and 12 months postoperatively to record the appearance, colour, texture, recurrence of infection, and knee extension function of the flap donor site.Results:According to the preoperative design, the perforator flaps were harvested and transferred in all the 8 patients. All flaps survived and the recipient and donor sites healed in one stage. All patients entered postoperative follow-up for 3 to 12 (mean, 8.6)months. The colour and texture of the flaps were excellent, and the appearance of donor and recipient sites was satisfactory. Two patients with hand injuries were evaluated using the brief Michigan Hand Outcomes Questionnaire (MHQ), with scores of 43.74 and 81.25, respectively. Six patients with lower limb injuries were evaluated using the Maryland foot score, with scores of 2 excellent, 3 good and 1 fair.Conclusion:The application of AR navigation can effectively assist the design of a chimeric twin-paddled ALTPF. It also provides an effective basis for clinical personalised flap design.
