Super-pulse thulium fiber laser (hereinafter referred to as thulium laser) has shown broad application prospects in medical research, especially in the treatment of urinary tract stones.Thulium laser has a thin fiber diameter, which reduces the occupation of the working channel and increases the irrigation water flow.Currently, the peak power reaches up to 500 W, the single pulse energy to 6 J, and the frequency to 2000 Hz.The stone-breaking mechanism of thulium laser is photothermal and photomechanical.Different combinations of energy and frequency will significantly affect the volume of stone fragments. "High energy and low frequency" is more suitable for "fragmentation" stone breaking, while "low energy and high frequency" is more suitable for "powderization" stone breaking.Some in vitro experiments have confirmed that thulium laser has higher stone-breaking efficiency, less stone displacement, and more obvious thermal effects compared to holmium laser.Clinically, thulium laser has been applied to ureteroscopic lithotripsy and percutaneous nephrolithotomy., and the stone free rate and safety are relatively high.This article reviews the stone-breaking principles, in vitro experiments, and clinical applications of thulium laser, aiming to provide better theoretical support and practical experience for the development and application of super-pulse thulium fiber laser in the future.

Based on the "Qi-blood-meridians" system， it is proposed that recurrence after radiofrequency ablation （RFA） for arrhythmia originates from damage to the heart and injury to the meridians caused by thermal burns. Disorder of qi movement， blood obstruction and heat constraint are the prerequisites for recurrence， while internal consumption of deficient qi， yin damage and scarce blood are key factors in frequent episodes. Latent pathogen of both phlegm and stasis， along with condensation of pathogenic yin， is the main cause of disease progression. Accordingly， self-made Tong Xin Beverage （通心饮） with 18 herbs is used throughout the postoperative intervention process to nourish the heart， unblock the meridians， restore vessels in balance of yin and yang. Self-made Qingxin Dingji Decoction （清心定悸汤） can be used to promote qi movement， diffuse stagnation， relieve heat and activate blood circulation so as to facilitate early recovery. Self-made Peiben Yangxin Decoction （培本养心汤） can boost qi and nourish yin， harmonize the ying （营） level and nourish blood， thereby improving long-term prognosis. In addition， Shiwei Wendan Decoction combined （十味温胆汤） with Taoren Honghua Decoction （桃仁红花煎） resolves phlegm， dissipates masses， removes stasis， and softens hardness， which can be used to prevent disease aggravation. These approaches aim to provide ideas and references for clinical practice.

Under the background of carbon peaking and carbon neutrality goals, the Ministry of Ecology and Environment, together with 15 national ministries and commissions, has formulated the Implementation Plan on Establishing a Carbon Footprint Management System, and it is urgent for traditional Chinese medicine(TCM) pharmaceutical enterprises to carry out research on carbon footprint accounting methods of related products. Based on the life cycle assessment(LCA) theory, taking mulberry leaf extract produced by a certain enterprise as an example, this study analyzed the carbon footprint of TCM extracts during the life cycle. The results show that for every 1 kg of product produced, the carbon emissions from the stages of raw material acquisition, transportation, and extract production are-20.569, 1.205, and 173.577 kgCO_2eq(CO_2 equivalent), respectively. The carbon footprint of the product is 154.213 kgCO_2eq·kg~(-1). In addition, the carbon emission is the highest in the production stage, in which the consumption of ethanol solvents makes the greatest contribution to the carbon footprint, accounting for 25.71%, more than one-fourth of the total carbon footprint. The second contribution was from the treatment process of TCM residues, accounting for 19.67%, closely followed by wastewater treatment(17.71%), the consumption of hot steam(17.43%), and drinking water(16.90%). The consumption of electric power and packaging materials has a smaller carbon emission of 2.58%. In particular, the carbon emission caused by the consumption of packaging materials is only 0.04%, which is negligible. The results of the study are expected to provide a reference for TCM enterprises to carry out research on the carbon footprint of products, offer ideas for collaborative innovation in reducing pollution and carbon emissions throughout the entire industry chain of TCM, and develop new quality productivity of modern TCM industry based on green and low-carbon manufacturing.

In order to realize the quantitative assessment of muscle strength in hand function rehabilitation and then formulate scientific and effective rehabilitation training strategies, this paper constructs a multi-scale convolutional neural network (MSCNN) - convolutional block attention module (CBAM) - bidirectional long short-term memory network (BiLSTM) muscle strength prediction model to fully explore the spatial and temporal features of the data and simultaneously suppress useless features, and finally achieve the improvement of the accuracy of the muscle strength prediction model. To verify the effectiveness of the model proposed in this paper, the model in this paper is compared with traditional models such as support vector machine (SVM), random forest (RF), convolutional neural network (CNN), CNN - squeeze excitation network (SENet), MSCNN-CBAM and MSCNN-BiLSTM, and the effect of muscle strength prediction by each model is investigated when the hand force application changes from 40% of the maximum voluntary contraction force (MVC) to 60% of the MVC. The research results show that as the hand force application increases, the effect of the muscle strength prediction model becomes worse. Then the ablation experiment is used to analyze the influence degree of each module on the muscle strength prediction result, and it is found that the CBAM module plays a key role in the model. Therefore, by using the model in this article, the accuracy of muscle strength prediction can be effectively improved, and the characteristics and laws of hand muscle activities can be deeply understood, providing assistance for further exploring the mechanism of hand functions .

Mitochondrial DNA (mtDNA) acts as a damage-associated molecular pattern to activate the stimulator of interferon genes (STING) signaling in macrophages, promoting tissue inflammation. However, its role in acute myocardial infarction (AMI) remains unclear. Macrophage-specific Sting1 knockout mice were used to validate STING's pathological role in AMI. Cardiac and liver mtDNA were used to activate macrophages in co-culture systems with cardiomyocytes to assess fibrosis and hypertrophy. Panaxatriol saponin (PTS) was tested for its ability to block mtDNA-driven macrophage activation and subsequent cardiomyocyte damage. STING-PTS binding ability was analyzed. AMI rats received PTS to evaluate its effects on myocardial inflammation and ventricular remodeling. In vivo, macrophage-specific Sting1 knockout reduced myocardial inflammation and injury after AMI. In vitro, mtDNA-activated macrophages induced cardiomyocyte fibrosis and hypertrophy through STING signaling. PTS suppressed mtDNA-driven macrophage activation by directly binding STING, thereby blocking inflammatory cascades. In AMI rats, PTS treatment attenuated acute inflammation and reversed ventricular remodeling. These findings establish the mtDNA-STING axis in macrophages as a critical driver of post-AMI inflammation and identify pharmacological STING inhibition with PTS as a promising therapeutic strategy. The study bridges genetic validation with translational applications, highlighting macrophage STING as a novel target for ischemic heart disease management.

Hepatic fibrosis is the common key pathological link of various chronic liver diseases and can progress to malignant diseases such as liver cirrhosis and hepatocellular carcinoma； however， there is still a lack of effective targeted therapeutic drugs at present. Traditional Chinese medicine （TCM） has a marked clinical effect in the prevention and treatment of hepatic fibrosis， yet its precise clinical application and global promotion are greatly limited by the complex components of compound prescriptions and unclear mechanism of action. In recent years， multimodal high-throughput omics technology has achieved rapid development， providing strong technical support for elaborating on the scientific connotation of TCM in the treatment of complex diseases due to its advantages of systematic profiling， big-data analytics， and precise target prediction. In particular， integrated transcriptomic， proteomic， and metabolomic strategies comprehensively elucidate key signaling networks， cellular phenotypic transitions， and extracellular matrix metabolic homeostasis modulated by TCM compounds and monomers and assist in the screening and assessment of effective component groups and novel biomarkers. This article systematically reviews the advances in basic research on TCM prevention and treatment of hepatic fibrosis based on multi-omics technologies in the past five years， summarizes the “drug-target-pathway-phenotype” regulatory network， and elaborates on the core mechanisms of TCM in regulating hepatic stellate cell activation and reversing hepatic fibrosis. Future studies should further delve into the interdisciplinary integration and dynamic analytical methodologies of multi-omics technologies， precisely identify the core regulatory target networks modulated by TCM， and systematically unravel the scientific connotation of compatibility rule in compound prescriptions， in order to provide a theoretical basis for developing efficient targeted drugs for hepatic fibrosis and individualized diagnosis and treatment strategies.

Objective:To summarize the thinking and compatibility law of TCM in the treatment of stable angina pectoris (SAP) based on syndrome differentiation using data mining technology.Methods:The clinical studies of TCM treatment for SAP in databases of CNKI, Wanfang Data, VIP and SinoMed China Biomedical Literature Service System were retrieved from the establishment of the databases to February 28, 2022. The frequency statistic, clustering analysis and association rule analysis of TCM data were conducted using Clementine 12.0, Excel 2016, SPSS Statistics 22.0 software, and core prescriptions were summarized.Results:Totally 289 prescriptions were included, involving 185 kinds of Chinese materia medica, including 38 TCM syndrome types. Based on the overall study of SAP "disease", the clinical treatment of SAP was mainly based on the drugs for activating blood circulation and removing blood stasis, tonifying deficiency and strengthening healthy qi, and regulating qi and resolving phlegm. The single Chinese materia medica with high frequency of use were Chuanxiaong Rhizoma, Salviea Miltiorrhizae Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Angelicae Sinensis Radix, etc. The commonly used drug pairs included Chuanxiaong Rhizoma-Angelicae Sinensis Radix, Chuanxiaong Rhizoma-Carthami Flos, Chuanxiaong Rhizoma-Aurantii Fructus Immaturus, etc. The drug complex network diagram and clustering analysis showed that the prescription of Buyang Huanwu Decoction was the basic prescription for the treatment of SAP; based on the specific research of SAP "syndrome", the most common TCM syndromes of SAP were qi deficiency and blood stasis, phlegm and blood stasis, and qi stagnation and blood stasis. The drug properties of the three drugs were mainly warm and mild; the tastes were mainly sweet, pungent and bitter, and most of them belong to the liver, spleen, lung and heart meridian; in terms of specific medication, the basic prescription of qi deficiency and blood stasis syndrome was Buyang Huanwu Decoction, which was composed of high-frequency drugs such as Angelicae Sinensis Radix, Chuanxiaong Rhizoma, Salviea Miltiorrhizae Radix et Rhizoma, etc; The phlegm and blood stasis syndrome was often based on the Gualou Xiebai Banxia Decoction and Taohong Siwu Decoction, which were composed of high frequency drugs such as Pinelliae Rhizoma, Chuanxiaong Rhizoma, Allii Macrostemonis Bulbus, etc; the basic prescription of qi stagnation and blood stasis syndrome was Xuefu Zhuyu Decoction, which was composed of high frequency drugs such as Chuanxiaong Rhizoma, Angelicae Sinensis Radix, Aurantii Fructus. Drug clustering analysis showed that both qi deficiency and blood stasis syndrome and qi stagnation and blood stasis syndrome were divided into 3 categories, and phlegm and blood stasis syndrome were divided into 4 categories.Conclusions:Deficiency, blood stasis, phlegm and stagnation are important pathological factors of SAP, in which qi deficiency is the basis of SAP, blood stasis runs through the disease, or both phlegm and qi stagnation. Focusing on the pathogenesis of deficiency in root and excess in superficiality, drugs with the efficacy of tonifying the deficiency and promoting blood circulation and removing blood stasis are used in clinical treatment, according to different syndrome differentiation of prescription selection.

CAPOS syndrome is an autosomal dominant neurological disorder caused by mutations in the ATP1A3 gene. Initial symptoms, often fever-induced, include recurrent acute ataxic encephalopathy in childhood, featuring cerebellar ataxia, optic atrophy, areflflexia, sensorineural hearing loss, and in some cases, pes cavus. This report details a case of CAPOS syndrome resulting from a maternal ATP1A3 gene mutation. Both the child and her mother exhibited symptoms post-febrile induction,including severe sensorineural hearing loss in both ears, ataxia, areflexia, and decreased vision. Additionally, the patient's mother presented with pes cavus. Genetic testing revealed a c. 2452G>A（Glu818Lys） heterozygous mutation in theATP1A3 gene in the patient . This article aims to enhance clinicians' understanding of CAPOS syndrome, emphasizing the case's clinical characteristics, diagnostic process, treatment, and its correlation with genotypeic findings.
