Flexible conductive fibers have been widely applied in wearable flexible sensing. However, exposed wearable flexible sensors based on liquid metal (LM) are prone to abrasion and significant conductivity degradation. This study presented a high-sensitivity LM conductive fiber with integration of strain sensing, electrical heating, and thermochromic capabilities, which was fabricated by coating eutectic gallium-indium (EGaIn) onto spandex fibers modified with waterborne polyurethane (WPU), followed by thermal curing to form a protective polyurethane sheath. This fiber, designated as Spandex/WPU/EGaIn/Polyurethane (SWEP), exhibits a four-layer coaxial structure: spandex core, WPU modification layer, LM conductive layer, and polyurethane protective sheath. The SWEP fiber had a diameter of (458.3 ± 10.4) μm, linear density of (2.37 ± 0.15) g/m, and uniform EGaIn coating. The fiber had excellent conductivity with an average value of (3 716.9 ± 594.2) S/m. The strain sensing performance was particularly noteworthy. A 5 cm × 5 cm woven fabric was fabricated using polyester warp yarns and SWEP weft yarns. The fabric exhibited satisfactory moisture permeability [(536.06 ± 33.15) g/(m ²·h)] and maintained stable thermochromic performance after repeated heating cycles. This advanced conductive fiber development is expected to significantly promote LM applications in wearable electronics and smart textile systems.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Objective:To investigate the impact of receptor-interacting protein kinase 3 (RIPK3) on major adverse cardiovascular events (MACE) in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI), as well as the predictive performance of RIPK3 combined with traditional cardiovascular risk factors.Methods:This study was a single-center prospective cohort study. It included patients with AMI who underwent PCI at Peking Union Medical College Hospital between September 2017 and November 2017. Baseline clinical data were collected, and plasma samples were obtained 6 hours after PCI to measure RIPK3 levels. Follow-up was conducted via outpatient visits or phone calls to record the occurrence of MACE, including cardiovascular death, hospitalization for heart failure, and vascular events (recurrent AMI or stroke). The predictive performance of RIPK3, traditional cardiovascular risk factors and their combination for MACE was compared using receiver operating characteristic (ROC) curves. Patients were divided into low- and high-RIPK3 level groups based on the optimal cutoff value of RIPK3. Multivariate Cox proportional hazards regression analysis was used to assess the impact of RIPK3 levels on MACE after PCI in AMI patients. Kaplan-Meier survival curves were plotted, and the log-rank test was used to compare MACE incidence between the low-and high-RIPK3 groups.Results:A total of 103 AMI patients who underwent PCI were included, aged 63.0 (56.0, 69.0) years, and 83 (80.6%) were male. The follow-up time was 5.17 (2.81, 5.17) years, during which 44 patients (42.7%) experienced MACE. The ROC curve analysis showed that the area under the curve ( AUC) for traditional cardiovascular risk factors was 0.68 (95% CI: 0.58-0.78), while the AUC for plasma RIPK3 was 0.72 (95% CI: 0.62-0.82). The combined AUC for traditional risk factors and RIPK3 was 0.75 (95% CI: 0.65-0.85). Multivariate Cox proportional hazards regression analysis indicated that plasma RIPK3 level is greater than or equal to the optimal cutoff value of 440.9 μg/L ( HR=3.31, 95% CI: 1.53-8.30, P=0.005) was an independent risk factor for MACE in AMI patients after PCI. Kaplan-Meier survival analysis demonstrated that the high-RIPK3 group had a significantly higher risk of MACE after PCI compared to the low-RIPK3 group (log-rank P=0.006). Conclusions:Elevated plasma RIPK3 level is an independent risk factor for MACE in AMI patients after PCI. Plasma RIPK3 combined with traditional cardiovascular risk factors can more effectively predict the occurrence of MACE in AMI patients after PCI. AMI patients with RIPK3≥440.9 μg/L have a higher risk of MACE after PCI.

Objective:To observe the clinical efficacy of a new type of "firebreak" drainage with skin preservation in the treatment of Fournier's gangrene.Methods:This technique is suitable for patients with perianal necrotizing fasciitis who can tolerate surgery without large area of skin blackness and necrosis. Procedure and key points: (1) The dividing line between inflammatory tissue and normal tissue was determined according to imaging examination and intraoperative exploration; (2) The abscess cavity was cut along the most obvious part of the abscess fluctuation, with a long diameter of 3~4 cm and a short diameter of 1~2 cm; (3) Necrotic tissue was discreetly separated and removed from the main incision to the outer edge of the infection. A fusiform incision was made every 3 to 5 cm, with a long diameter of 2 to 3 cm and a short diameter of 1 cm, and discreetly separated until the normal tissue, and a hose was hung between the adjacent incisions for drainage. (4) Each adjacent edge cut between the stealth separation and hanging hose drainage, forming a "firebreak"; (5) Rinse the wound repeatedly; (6) If the infection invades the rectum, colostomy is performed as required. The case data of 11 patients with perianal necrotizing fasciitis admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from July 2019 to February 2023 were retrospectively analyzed. All patients were treated with emergency surgical debridement by "firebreak" drainage with skin preservation.Results:All 11 cases were cured with 100%. One case underwent multiple operations. The hospitalization time was 11-46 days, with an average of 22 days. The wound healing time was 28-75 days, with an average of 43 days. Except for 1 patient with trauma, all the other patients had no significant anal function injury after surgery. All the 11 patients recovered and were discharged from hospital with a median follow-up of 136 (115-413) days.Conclusions:The "firebreak" drainage based on skin preservation has the advantages of less trauma and faster recovery, and do not cause obvious anal function damage.

Objective To investigate the correlation between the characteristics of peritumoral edema and the aggressiveness of breast invasive ductal carcinoma in preoperative magnetic resonance imaging(MRI).Methods A total of 79 patients(79 lesions)who underwent radical mastectomy in the First Affiliated Hospital of Ningbo University from January 2020 to May 2021 and were pathologically diagnosed as invasive ductal carcinoma were included in invasive ductal carcinoma group,and 45 patients(49 lesions)with benign breast lesions were included in benign lesion group during the same period.The difference of peritumoral edema between two groups and the relationship between different pathological features of invasive ductal carcinoma and peritumoral edema were compared.Results The peritumoral edema in benign lesion group was significantly less severe than that in invasive ductal carcinoma group(χ2=25.330,P<0.05).The tumor size of invasive ductal carcinoma group was positively correlated with the degree of peritumoral edema(r=0.381,P<0.05).There were significant differences in molecular type,histological grade,T stage,lymph node metastasis and Ki-67 expression level among patients with different peritumoral edema grades(P<0.05).Ki-67 expression level and the number of lymph node metastasis were positively correlated with the degree of peritumoral edema(r=0.348,0.273,P<0.05).Conclusion The degree of peritumoral edema in MRI correlates with the aggressiveness of breast invasive ductal carcinoma and can be used as one of the tools to evaluate breast carcinoma.

Sjögren's syndrome （SS）， a disorder of immune system， is one of the dominant diseases treated by traditional Chinese medicine （TCM）. China Association of Chinese Medicine organized experts in the field of TCM and western medicine rheumatology and pharmacology to discuss the advantages and optimal regimens of TCM for the treatment of SS. The experts generally agreed on the low early diagnosis rate of SS and the lack of targeted therapeutic drugs. In addition， autoimmune abnormality is the key factor in the occurrence of SS and deficiency of both Qi and Yin is the core pathogenesis. SS has unique tongue manifestations， which is expected to allow for the early diagnosis and treatment with integrated traditional Chinese and western medicine. TCM has advantages in treating SS in terms of alleviating clinical symptoms and systemic involvement， individualized treatment， relieving sleep and mood disorders， preventing the occurrence in the early stage， and enhancing the effectiveness and reducing toxicity in the treatment by integrated TCM and western medicine. In general， TCM has advantages in different stages of SS. Internal and external use of TCM， acupuncture， and acupotome are all available options. The optimal regimens should be determined on the basis of pattern identification， stage of disease， and the advantages of TCM. Clinical characteristics and biomarkers of SS should be studied to classify patients， so as to design precision evidence-based TCM regimens for SS. On the basis of unique tongue manifestations of SS， models for early diagnosis and poor prognosis identification of SS should also be established to achieve early prevention and treatment and to improve the prognosis. In the future， we should vigorously carry out high-quality evidence-based medical research on the treatment of SS by TCM and integrated traditional Chinese and western medicine and develop relevant guidelines to optimize and standardize current diagnosis and treatment， thereby laying a basis for clarifying and explaining the advantages of TCM in treating SS.

The dynamic changes of cognitive function has been paid more and more attention by foreign scholars.Dynamic assessment based on ecological momentary assessment(EMA)can capture subtle changes in cognitive function and provide more comprehensive information for early identification and timely intervention of people with cognitive impairment, which is an effective supplement to traditional cognitive assessment.This paper reviewed the concept of ecological momentary assessment, its advantages in cognitive assessment, its feasibility and effectiveness, and its application status in the evaluation of cognitive function in the elderly, so as to provide a reference for making ecological assessment of the cognitive function for older adults that is in line with China's national conditions.

Chinese medicine entered a significant period from foundation to maturity between Han and Tang dynasties when the Chinese traditional stomatology was a key stage. Sorting and analysis of existing literature and research outcomes have showed that current research on stomatology between Han and Tang dynasties focuses on oral physiology, pathology, diagnosis and treatment, and health care. It also involves stomatology history and explanation of termino-logies related to mouth and teeth recorded in medical books, use of simple methods, and thinking with citation and analysis of literature simply listed and reasoning preliminarily deducted. From the macro perspective, current research has not unveiled the whole picture of stomatology between the two dynasties and left a series of key issues unresolved. Thus, new methods should be developed and employed to carry out medical research on stomatology between Han and Tang dynasties given that is has a prosperous future.
