This paper outlines the development of artificial intelligence （AI） and its applications in traditional Chinese medicine （TCM） research， and elucidates the roles and advantages of large language models， knowledge graphs， and natural language processing in advancing syndrome identification， prescription generation， and mechanism exploration. Using spleen-stomach diseases as an example， it demonstrates the empowering effects of AI in classical literature mining， precise clinical syndrome differentiation， efficacy and safety prediction， and intelligent education， highlighting an upgraded research paradigm that evolves from data-driven and knowledge-driven approaches to intelligence-driven models. To address challenges related to privacy protection and regulatory compliance in cross-institutional data collaboration， a "trusted federated evidence-based analysis platform for TCM spleen-stomach diseases" is proposed， integrating blockchain-based smart contracts， federated learning， and secure multi-party computation. The deep integration of AI with privacy-preserving computing is reshaping research and clinical practice in TCM spleen-stomach diseases， providing feasible pathways and a technical framework for building a high-quality， trustworthy TCM big-data ecosystem and achieving precision syndrome differentiation.

BACKGROUND: Tissue engineering holds promise for vascular repair and regeneration by mimicking the extracellular matrix of blood vessels. However, achieving a functional and thick vascular wall with aligned fiber architecture by electrospinning remains a significant challenge. METHODS: A novel electrospinning setup was developed that utilizes an auxiliary electrode and a spring. The impact of process parameters on fiber size and morphology was investigated. The structure and functions of the scaffolds were evaluated through material characterization and assessments of cellular biocompatibility. RESULTS: The new setup enabled controlled deposition of fibers in different designed orientations. The fabricated small-diameter vascular scaffolds consisted of an inner layer of longitudinally oriented fibers and an outer layer of circumferentially oriented fibers (L + C vascular scaffold). Key parameters, including rotational speed, the utilization of the auxiliary electrode, and top-to-collector distance (TCD) significantly influenced fiber orientation. Additionally, voltage, TCD, feed rate, needle size, auxiliary electrode and collector-auxiliary electrode distance affected fiber diameter and distribution. Mechanical advantages and improved surface wettability of L + C vascular scaffold were confirmed through tensile testing and water contact angle. Cellular experiments indicated that L + C vascular scaffold facilitated cell adhesion and proliferation, with human umbilical vein endothelial cells and smooth muscle cells attaching and elongating along the fiber direction of the inner and outer layer, respectively. CONCLUSION This study demonstrated the feasibility of fabricating fiber-aligned, thick-walled vascular scaffolds using a modified electrospinning setup. The findings provided insights into how the auxiliary electrode, specific collector influenced fiber deposition, potentially advancing biomimetic vascular scaffold engineering.

A 36-year-old male presented to the Department of Neurosurgery of the Second People′s Hospital of Hunan Province on February 12, 2024, due to "10 days of aggravated paroxysmal headache and 1 day of mental abnormality". Ten days ago, after catching a cold, the patient developed persistent low fever and paroxysmal headache. On February 12, 2024, acuted mental and behavioral abnormalities developed, including slow response, self-talk, defecation and urination, no sense of shame and other mental and behavioral abnormalities. On February 22nd, metagenomic next-generation sequencing (mNGS) in cerebrospinal fluid confirmed feline rickettsia infection. One week after doxycycline anti-rickettsia treatment, cerebrospinal fluid mNGS results indicated that the etiology turned negative, and the clinical symptoms improved. Mental disorders caused by rickettsial encephalitis in cats are rare but clinically significant. This case highlights the diagnostic value of mNGS in critical and difficult cases, and supports its integration with traditional diagnostic techniques to achieve precision medicine.

Objective:To compare the efficacy of biplanar fixation combined with bone grafting and proximal femoral nail anti-rotation (PFNA) in the treatment of critically complicated osteoporotic intertrochanteric femoral fracture .Methods:A retrospective cohort study was conducted to analyze the clinical data of 28 patients with critically complicated osteoporotic intertrochanteric femoral fracture, admitted to Union Hospital, Tongji Medical College of Huazhong University of Science and Technology from January 2020 and December 2022, including 3 males and 25 females, aged 70-91 years [(79.4±6.3)years]. T score for bone mineral density was -2.5~-4.1 SD［（-3.3±0.6）SD］. All the patients were found with type A2.2-A3.3 fracture based on AO classification, and were complicated with trochanteric lateral wall fracture. Among them, 16 patients underwent biplanar fixation combined with bone grafting (biplanar fixation group), while 12 underwent PFNA internal fixation (PFNA group). All the patients received anti-osteoporosis therapy after surgery. The two groups were compared in terms of the operative time, intraoperative blood loss, hemoglobin levels at 3 days postoperatively, and time to weight-bearing. The visual analogue scale (VAS) scores and Harris hip scores at 1, 3, 6 months postoperatively, and at the last follow-up and the incidence of complications were also detected in the two groups.Results:All the patients were followed up for 12-16 months [(14.1±1.4)months]. In the biplanar fixation group, the operative time was (75.1±15.3)minutes, significantly longer than (45.6±14.2)minutes in the PFNA group ( P<0.01); the intraoperative blood loss was (234.1±11.8)ml, significantly more than (170.0±13.4)ml in the PFNA group ( P<0.01); the hemoglobin level at 3 days postoperatively was (82.6±9.3)g/L in the biplanar fixation group, higher than (64.8±6.8)g/L in the PFNA group ( P<0.01). The time to weight-bearing was (1.1±0.7)weeks in the biplanar fixation group, significantly shorter than (3.2±1.2)weeks in the PFNA group ( P<0.01). There were no statistically significant differences between the two groups in VAS scores and Harris hip scores at 1, 3, 6 months postoperatively, and at the last follow-up ( P>0.05). The VAS scores and Harris hip scores in the two groups were gradually improved with the prolongation of postoperative time ( P<0.05 or 0.01). No complications such as neurovascular injuries were observed in either group. One patient in the biplanar fixation group developed lower extremity deep vein thrombosis (DVT), with a complication rate of 6.3%, while 2 patients in the PFNA group developed lower extremity DVT and 4 hypostatic pneumonia, with a complication rate of 50.0% ( P<0.05). Conclusion:Compared with PFNA internal fixation, biplanar fixation with bone grafting has the advantages of less postoperative blood loss, earlier weight-bearing exercises and lower incidence of complications in the treatment of critically complicated osteoporotic intertrochanteric femoral fracture, despite longer operative time and more intraoperative blood loss.

Non-small cell lung cancer (NSCLC) accounts for the majority of lung cancer cases and remains the leading cause of cancer-related mortality worldwide. Firstly, this review explores the limitations of conventional therapies, chemotherapy, radiotherapy, and surgery, focusing on the development of drug resistance and significant toxicity that often hinder their efficacy. Thereafter, advancements in targeted therapies, such as immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs), are discussed, highlighting their impact on improving outcomes for patients with specific genetic mutations, including c-ros oncogene 1 receptor tyrosine kinase (ROS1), anaplastic lymphoma kinase (ALK), and epidermal growth factor receptor (EGFR). Additionally, the emergence of novel immunotherapies and phytochemicals is examined, emphasizing their potential to overcome therapeutic resistance, particularly in advanced-stage diseases. The review also delves into the role of next-generation sequencing (NGS) in enabling personalized treatment approaches and explores the clinical potential of innovative agents, such as bispecific T-cell engagers (BiTEs) and antibody-drug conjugates (ADCs). Finally, we address the socioeconomic barriers that limit the accessibility of these therapies in low-resource settings and propose future research directions aimed at improving the long-term efficacy and accessibility of these treatments.
