Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Cardiovascular diseases and psychological disorders represent two major threats to human physical and mental health. Research on electrocardiogram (ECG) signals offers valuable opportunities to address these issues. However, existing methods are constrained by limitations in understanding ECG features and transferring knowledge across tasks. To address these challenges, this study developed a multi-resolution feature encoding network based on residual networks, which effectively extracted local morphological features and global rhythm features of ECG signals, thereby enhancing feature representation. Furthermore, a model compression-based continual learning method was proposed, enabling the structured transfer of knowledge from simpler tasks to more complex ones, resulting in improved performance in downstream tasks. The multi-resolution learning model demonstrated superior or comparable performance to state-of-the-art algorithms across five datasets, including tasks such as ECG QRS complex detection, arrhythmia classification, and emotion classification. The continual learning method achieved significant improvements over conventional training approaches in cross-domain, cross-task, and incremental data scenarios. These results highlight the potential of the proposed method for effective cross-task knowledge transfer in ECG analysis and offer a new perspective for multi-task learning using ECG signals.

To summarize the clinical experience and characteristics of Professor XU Xin in syndrome differentiation and treatment of polycystic ovary syndrome with insulin resistance （PCOS-IR）. XU Xin believes that the etiological factors of PCOS-IR is qi deficiency of the spleen and kidney， and the key disease mechanism is dysfunction in transportation and transformation of spleen and kidney， causing phlegm dampness and turbid heat accumulated in yangming， then evolving into the lower jiao， mixed with blood stasis， finally obstructing the chong （冲） and ren （任） mai and uterus. So in clinic， the method of boosting the kidney and fortifying the spleen was used through out the whole treatment commonly using modified Shoutai Pill （寿胎丸） and Sijunzi Decoction （四君子汤）. The main therapeutic method for treating PCOS-IR refers to clearing and draining dampness heat in yangming， invigorating blood and regulating period， with self-prescribed Yishen Quzhuo Formula （益肾祛浊方）， as a reference for the treatment of this disease.

Objective:To compare the efficacy of inverted triangular and equilateral triangular cannulated screw internal fixation (CSIF) in the treatment of femoral neck fracture (FNF) in young and middle-aged patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 52 patients with FNF admitted to Qingdao Central Hospital of Rehabilitation University from January 2020 to January 2022, including 18 males and 34 females, aged 28-60 years [(45.7±9.3)years]. Based on the Garden classification, the fractures were classified as type I in 11 patients, type II in 34, and type III in 7. According to Pauwels classification, the fractures were classified as type I in 33 patients, type II in 13, and type III in 6. Among them, 28 patients received inverted triangular CSIF (inverted triangle group) and 24 received equilateral triangular CSIF (equilateral triangle group). Before surgery and at 3 months after surgery, nuclear medicine three-phase bone scan and bone tomography imaging were performed to evaluate the proximal blood supply recovery in the fractured sites in the two groups. The Harris hip joint function scores before surgery, at 1 day, 3 months after surgery, and at the last follow-up, the posterior tilt angles of the femoral head before surgery and at 3 months after surgery, and the fracture nonunion rate and ischemic necrosis rate of the femoral head at the last follow-up were compared between the two groups.Results:All the patients were followed up for 18-30 months [(24.2±5.6)months]. Before surgery, the fracture of both groups showed extensive blood supply defects at the proximal end. At 3 months after surgery, the excellent and good rate of the proximal blood supply recovery in the inverted triangle group was 92.9% (26/28), significantly higher than 70.8% (17/24) in the equilateral triangle group ( P<0.05). The Harris hip joint function scores before surgery were (44.1±4.1)points and (43.5±5.1)points in the inverted triangle group and equilateral triangle group ( P>0.05). At 1 day, 3 months after surgery, and at the last follow-up, the Harris hip joint function scores in the inverted triangle group were (71.7±3.6)points, (87.0±3.6)points, and (88.7±2.6)points respectively, higher than those in the equilateral triangle group [(65.0±5.4)points, (80.5±5.2)points, and (82.6±4.0)points] ( P<0.05). In both groups, there were no significant differences between the Harris hip joint function scores at the last follow-up and those at 3 months after surgery ( P>0.05), which were all higher than those at 1 day after surgery ( P<0.05). The posterior tilt angles of the femoral head were (16.9±4.4)° and (16.8±5.0)° in the inverted triangle group and equilateral triangle group preoperatively ( P>0.05). At 3 months after surgery, the posterior tilt angles of the inverted femoral head were (8.9±1.9)° and (9.0±1.8)° in the inverted triangle group and equilateral triangle group ( P>0.05). The posterior tilt angles of the femoral head at 3 months after surgery were lower than those before surgery in both groups ( P<0.05). At the last follow-up, there were no statistically significant differences in the fracture nonunion rate and ischemic necrosis rate of the femoral head between the two groups ( P>0.05). Conclusion:Compared with equilateral triangle CSIF, inverted triangle CSIF achieves better recovery of the proximal blood supply and hip joint function in the treatment of femoral neck fracture in young and middle-aged patients.

Objective:To construct a temperature-sensitive hydrogel (PF-CA@AS-IV hydrogel) composed of Pluronic F-127 (PF-127)/calcium alginate (CA) loaded with astragaloside IV (AS-IV), and to explore its repair effect and potential mechanism on diabetic skin ulcers (DSU).Methods:The PF-CA@AS-IV hydrogel loaded with AS-IV and gelling at 37 ℃ was prepared. Its temperature sensitivity, rheological properties, and morphology were characterized. A rat model of DSU was established, and the rats were randomly divided into blank control group, model group, AS-IV spray group, PF-CA hydrogel group, and PF-CA@AS-IV hydrogel group ( n=5 each). After 21 days of intervention, the wound healing rate of each group was evaluated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of granulation tissue, and immunohistochemistry was applied to detect the expression level of CD34, a marker of new blood vessels. Results:Rheological analysis showed that the storage modulus (G′) of PF-CA@AS-IV hydrogel began to exceed the loss modulus (G″) at 33 ℃, and a stable three-dimensional network structure was formed at 37 ℃. Scanning electron microscopy confirmed its loose and porous microstructure. Animal experiment results indicated that compared with the blank control group, the model group had a significantly lower wound healing rate, massive infiltration of inflammatory cells, and fewer new capillaries and CD34 expression (all P<0.05). Compared with the model group, each treatment group can promote wound healing, reduce inflammatory infiltration and increase the positive expression of CD34 to varying degrees (all P<0.05), and the curative effect of PF-CA@AS-IV hydrogel group is the most significant, which is better than that of AS-IV spray group and PF-CA hydrogel group (all P<0.05). Conclusions:PF-CA@AS-IV hydrogel can effectively regulate inflammatory response and promote angiogenesis through sustained release of AS-IV, thereby accelerating DSU healing, and has good translational potential in the field of chronic wound repair.

Objective To present an assessment method based on oscillometric upper-arm cuff pressure wave for realizing home-based detection of arteriosclerosis.Methods An upper-arm cuff pressure wave acquisition device based on an electronic blood pressure monitor was designed to implement data collection for cuff inflation and deflation,as well as the 15 s pressure holding phase.Following preprocessing of the data collected during this holding phase,individual pulse waves were extracted for pulse decomposition analysis(PDA).A novel model that superimposed a logarithmic normal function with two Gaussian functions,and an optimization method that combined template matching and particle swarm optimization were proposed to efficiently and accurately extract PDA features.Gaussian process regression was employed for multifeature fusion analysis,leading to the proposal of a new predictive indicator for arteriosclerosis.Results The mean absolute error of PDA was less than 1.2%,and the average processing time for a single pulse wave was less than 0.2 s.The regression determination coefficient R2 between the obtained indicators and baPWV was 0.8178.Conclusion The analysis on upper-arm cuff pressure wave provides a new reference for non-invasive arteriosclerosis detection,and it can be applied to electronic blood pressure monitors for home-based monitoring,offering significant practical value.

This study aims to establish an efficient protoplast-mediated genetic transformation sys-tem for Pochonia chlamydosporia(P.chlamydosporia)to facilitate gene transformation,genetic modification,and subsequent biological function research.Through orthogonal testing,the study systematically optimized key factors influencing electroporation,including voltage,osmotic stabi-lizer,pulse time,nucleic acid concentration,and protoplast concentration.The results showed that the optimal electroporation conditions were:voltage of 250 V,osmotic stabilizer as 0.6 mol/L su-crose solution,pulse time of 10 ms,plasmid concentration of 1％,and protoplast concentration of 1×107 protoplasts/mL,yielding a transformation efficiency of 0.4 × 103 CFU/pg.The interaction analysis revealed that the five factors affected transformation efficiency in the following order:plasmid concentration＞protoplast concentration＞pulse time＞osmotic stabilizer type＞voltage.Based on the positive transformants,the study further evaluated their colony morphology,growth rate,conidial yield,mycelial dry weight,and the ability to infect the eggs of three types of animal gastrointestinal nematodes.The results indicated that the electroporation process did not signifi-cantly affect the biological functions of P.chlamydosporia.The transformants successfully ex-pressed enhanced green fluorescent protein(EGFP),and PCR analysis confirmed the successful in-tegration of the thiostrepton resistance gene.In conclusion,this study successfully established a protoplast-based electroporation-mediated genetic transformation system for P.chlamydosporia,providing a valuable foundation for further research into the mechanism of egg parasitism and the underlying genes involved in its biocontrol activity.

The pathogenesis and progression of depression are closely associated with functional dysregula-tion in the brain's reward and emotion-modulating circuits.As the central hub of the reward system,the nucleus accumbens(NAc)forms aberrant neural circuits with multiple brain regions-including the ventral tegmental area(VTA),medial prefrontal cortex(mPFC),amygdala(AMY),hippocampus(HIP),and paraventricular nucleus of the thalamus(PVT)-which have been empirically linked to depressive symptomatology.Acupuncture,with its multi-target therapeutic profile,aligns well with the multifactorial and multisystem dysregulation characteristic of depressive disorders.This review systematically examines the functional alterations of the NAc-centered neural circuitry in depression and explores the potential mechanisms of acupuncture intervention.Evidence suggests that acupuncture holistically ameliorates depression by:modulating dopaminergic transmission in the VTA-NAc pathway,enhancing neurotransmitter equilibrium in the mPFC-NAc circuit,bidirectionally regulating emotional stability via the AMY-NAc loop,attenuating HIP-NAc glutamatergic hyperactivity,and optimizing excitatory signaling in the thalamus-NAc circuit.Furthermore,this synthesis emphasizes a systems-level integration of circuit mechanisms,highlighting both the clinical applicability of acupuncture in depression treatment and recent advances in mechanistic research.The findings provide robust theoretical foundations and practical guidance for clinical practice,bridging translational neuroscience with therapeutic innovation.
