To explore the advantages of traditional Chinese medicine (TCM) and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications (DMC), refine key pathophysiological insights and treatment principles, and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine, hosted by the China Association of Chinese Medicine, was held in Beijing, 2024. Experts in TCM, Western medicine, and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis, diagnostic and treatment challenges, and mechanism research related to DMC, ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development, research prioritization, and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM, strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Objective To explore the application value of dual-phase dual-energy CT (DECT) perfusion imaging in preoperative lung function assessment of lung cancer patients. Methods Data were collected from patients with stageⅠA non-small cell lung cancer who underwent surgical treatment in the Department of Thoracic Surgery, the First Affiliated Hospital of Nanjing Medical University, from November 2022 to June 2024. All patients underwent DECT perfusion imaging and pulmonary function testing (PFT) before surgery. PFT observation indicators included ventilation function indicators such as forced expiratory volume in one second (FEV1), forced vital capacity (FVC), 1-second rate (FEV1/FVC), maximal voluntary ventilation (MVV), and diffusion function indicators such as diffusing capacity for carbon monoxide (DLCO) and DLCO per liter of alveolar volume (DLCO/VA). The software eXamine was used to obtain quantitative parameters of DECT perfusion imaging, including volume parameters and perfusion parameters of both lungs and each lung lobe. The correlation between the volume parameters and perfusion parameters of both lungs and the ventilation and diffusion function indicators of the patients, as well as the differences in quantitative parameters of each lung lobe, was analyzed. Results The end-inspiration lung volume and biphasic volume difference were strongly positively correlated with FEV1 and FVC (r=0.636, r=0.682, r=0.614, r=0.624, P<0.001) and moderately positively correlated with MVV and DLCO (r=0.499, r=0.514, r=0.549, r=0.447, P<0.001); the end-expiration lung volume was weakly negatively correlated with DLCO/VA (r=−0.295, P=0.026); the volume ratio was positively correlated with FEV1, FVC, MVV, and MVV% (r=0.424, r=0.399, r=0.415, r=0.310, P<0.05); the end-inspiration iodine content was weakly positively correlated with DLCO/VA% (rs=0.292, P=0.030); the end-expiration iodine content was weakly positively correlated with FEV1, FVC, MVV, DLCO%, and DLCO/VA (r=0.307, r=0.299, r=0.295, r=0.366, r=0.320, P<0.05) and moderately positively correlated with DLCO (r=0.439, P<0.001); the end-inspiration iodine concentration was negatively correlated with FEV1, FVC, MVV, and MVV% (rs=−0.407, rs=−0.426, rs=−0.352, rs=−0.277, P<0.05); the end-expiratory phase iodine concentration was moderately positively correlated with DLCO/VA (r=0.403, P=0.002); both the iodine concentration difference and the iodine concentration ratio were moderately positively correlated with FEV1, FEV1%, FVC, MVV, MVV% (P<0.05). The lung volume and iodine concentration ratio values were both highest in the left upper lung lobe and lowest in the right middle lung lobe; the differences in lung volume, lung volume ratio, intrapulmonary iodine content, and intrapulmonary iodine concentration were all highest in the lower lobes of both lungs and lowest in the middle lobe of the right lung. Conclusion Dual-phase DECT perfusion imaging can accurately assess overall lung function and quantify regional lung function.

Objective:
To develop QingNangTCM, a specialized large language model (LLM) tailored for expert-level traditional Chinese medicine (TCM) question-answering and clinical reasoning, addressing the scarcity of domain-specific corpora and specialized alignment.
Methods:
We constructed QnTCM_Dataset, a corpus of 100 000 entries, by integrating data from ShenNong_TCM_Dataset and SymMap v2.0, and synthesizing additional samples via retrieval-augmented generation (RAG) and persona-driven generation. The dataset comprehensively covers diagnostic inquiries, prescriptions, and herbal knowledge. Utilizing P-Tuning v2, we fine-tuned the GLM-4-9B-Chat backbone to develop QingNangTCM. A multi-dimensional evaluation framework, assessing accuracy, coverage, consistency, safety, professionalism, and fluency, was established using metrics such as bilingual evaluation understudy (BLEU), recall-oriented understudy for gisting evaluation (ROUGE), metric for evaluation of translation with explicit ordering (METEOR), and LLM-as-a-Judge with expert review. Qualitative analysis was conducted across four simulated clinical scenarios: symptom analysis, disease treatment, herb inquiry, and failure cases. Baseline models included GLM-4-9B-Chat, DeepSeek-V2, HuatuoGPT-II (7B), and GLM-4-9B-Chat (freeze-tuning).
Results:
QingNangTCM achieved the highest scores in BLEU-1/2/3/4 (0.425/0.298/0.137/0.064), ROUGE-1/2 (0.368/0.157), and METEOR (0.218), demonstrating a balanced and superior normalized performance profile of 0.900 across the dimensions of accuracy, coverage, and consistency. Although its ROUGE-L score (0.299) was lower than that of HuatuoGPT-II (7B) (0.351), it significantly outperformed domain-specific models in expert-validated win rates for professionalism (86%) and safety (73%). Qualitative analysis confirmed that the model strictly adheres to the “symptom-syndrome-pathogenesis-treatment” reasoning chain, though occasional misclassifications and hallucinations persisted when dealing with rare medicinal materials and uncommon syndromes.
Conclusion
Combining domain-specific corpus construction with parameter-efficient prompt tuning enhances the reasoning behavior and domain adaptation of LLMs for TCM-related tasks. This work provides a technical framework for the digital organization and intelligent utilization of TCM knowledge, with potential value for supporting diagnostic reasoning and medical education.

ObjectiveThis paper aims to investigate the effects of Xixintang on aquaporin-4 (AQP4) polarity distribution, blood-brain barrier (BBB) function, and neuroinflammationin rats with Alzheimer's disease (AD), thereby revealing the potential mechanism through which this formula protects the BBB by regulating AQP4 polarization. The aim is to provide a scientific basis for clinical treatment. MethodsSixty Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, a probiotic group, a donepezil group, and an Xixintang group. The model was established by intraperitoneal injection of D-galactose (D-Gal) combined with bilateral intracerebroventricular injection of amyloid-β25-35 (Aβ25-35). The probiotic group (30.85 mg·kg-1), donepezil group (0.88 mg·kg-1), and Xixintang group (1.174 g·kg-1) received daily gavage administration, while the normal and model groups received intragastric administration with an equal volume of normal saline for one month. Cognitive ability was assessed by using the Morris water maze. BBB permeability was detected via Evans blue extravasation. The contents of interleukin-6 (IL-6), amyloid-β1-42 (Aβ1-42), and tumor necrosis factor-α (TNF-α) in the hippocampal tissues were measured by enzyme-linked immunosorbent assay (ELISA). The protein expressions of zonula occludens-1 (ZO-1), occludin, tissue inhibitor of metalloproteinase-1 (TIMP-1), matrix metalloproteinase-9 (MMP-9), and AQP4 in the hippocampal tissues were detected by western blot. The expression and co-localization levels of Aβ1-42, ionized calcium-binding adapter molecule 1 (IBA1), and AQP4/platelet endothelial cell adhesion molecule 31 (CD31) in the hippocampal region were examined by immunofluorescence. ResultsCompared with the normal group, the model group exhibited a significant decline in cognitive ability (P<0.01) and a marked increase in Evans blue extravasation in the brain (P<0.01). The expressions of ZO-1, occludin, and TIMP-1 were significantly decreased (P<0.01), while the expressions of AQP4 and MMP-9 were significantly increased (P<0.01). The co-localization level of AQP4/CD31 was significantly reduced (P<0.01), and the expressions of Aβ1-42, IL-6, TNF-α, and IBA1 were significantly elevated (P<0.01). Compared with the model group, the Xixintang group showed significant improvement in cognitive ability (P<0.01) and a significant reduction in Evans blue extravasation in the brain (P<0.01). The expressions of occludin, TIMP-1, and ZO-1 were significantly increased (P<0.05, P<0.01), while the expressions of AQP4 and MMP-9 were significantly decreased (P<0.05). The co-localization level of AQP4/CD31 was significantly enhanced (P<0.01), and the expressions of Aβ1-42, IL-6, TNF-α, and IBA1 were significantly reduced (P<0.05, P<0.01). ConclusionXixintang may improve cognitive function and alleviate AD pathology in AD model rats by regulating AQP4 polarity distribution, thereby breaking the vicious cycle of "Aβ deposition-neuroinflammation-BBB damage" and restoring the homeostasis of the microenvironment in the brain.

ObjectiveThis study aims to investigate whether Xixintang could ameliorate cognitive dysfunction in an Alzheimer's disease (AD) rat model induced by D-galactose and β-amyloid (Aβ25-35), by means of repairing the colonic mucosal barrier, regulating the Toll-like receptor 4 (TLR4)/nuclear factor-κB p65 (NF-κB p65) signaling pathway, and intervening in the pathological process mediated by the gut-brain axis. MethodsSixty specific pathogen-free (SPF) male Sprague-Dawley (SD) rats were randomly divided to five groups (n=12): A control group, a model group, a donepezil group, an Xixintang group, and a probiotic group. Except for those in the control group, rats in all other groups received daily intraperitoneal injections of D-galactose for six consecutive weeks. Subsequently, aggregated Aβ25-35 was injected stereotactically into the bilateral ventricles to establish the AD model. During the intervention periods, the rats in all groups were administered their respective drugs and normal saline by gavage. The Morris water maze test was used to assess the capacity for spatial learning and memory. Hematoxylin-eosin (HE) staining was employed to observe the histopathological changes in the colon tissues. Immunofluorescence was used to detect Aβ1-41 deposition in the hippocampal region and Mucin 2 (MUC2) expression in the colonic mucosa. Western blot was performed to measure the protein expression levels of FFAR2,TLR4, NF-κB p65, occludin (OCLN), zonula occludens-1 (ZO-1), and MUC2 in the colonic tissues. Enzyme-linked immunosorbent assay (ELISA) was used to determine the contents of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), serum amyloid A (SAA), and Aβ1-42 in the hippocampal region from the colonic tissues. The lipopolysaccharide (LPS) concentrations in colon tissues of rats were measured by using a dynamic chromogenic limulus assay. ResultsCompared with those in the control group, the rats in the model group exhibited a significantly prolonged escape latency and a markedly shorter duration in the target quadrant (P<0.01). The integrity of the colonic mucosal structure was compromised, with disordered gland arrangement and a reduced number of goblet cells. The Aβ1-42 deposition in the hippocampal region was significantly increased (P<0.01). The protein expression levels of TLR4 and NF-κB p65 in colonic tissues were significantly upregulated (P<0.01), while those of occludin and ZO-1 were downregulated (P<0.01). The contents of inflammatory factors such as IL-6, TNF-α, and SAA were significantly elevated (P<0.01), and the LPS level in the serum was markedly increased (P<0.01). In comparison to those in the model group, the rats in the Xixintang group showed a significantly shortened escape latency and a prolonged duration in the target quadrant (P<0.01). The colonic mucosal structure was ameliorated, with neat gland arrangement and an increased number of goblet cells. The Aβ1-42 deposition in the hippocampal region was reduced (P<0.01). The protein expressions of TLR4 and NF-κB p65 in the colon tissues were decreased (P<0.05,P<0.01), while the protein levels of occludin and ZO-1 were increased (P<0.01). The contents of IL-6, TNF-α, and serum amyloid A (SAA) were decreased (P<0.01), and the LPS level was reduced (P<0.01). ConclusionXixintang can significantly ameliorate cognitive dysfunction of AD model rats, by means of restoring the colonic mucosal barrier structure, reducing cerebral Aβ deposition, and suppressing peripheral and central inflammatory response. Its mechanism of action may be closely associated with the suppression of the TLR4/NF-κB signaling pathway activation, reduction of endotoxin levels, and regulation of the gut-brain axis.

This paper discussed the nature of ulcerative colitis, that is deficiency of the root and excess of the branch, from the theory of sweat pore, and to explore the theoretical basis and experience of treating this disease with retention enema of traditional Chinese medicine (TCM). The main location of this disease is in the intestine. As a part of sweat pore, the intestinal sweat pore serves as the gateway for the ascending, descending, exiting and entering of qi movement in the zang fu (脏腑) organs, meridians and collaterals, as well as the channel for the transportation of qi, blood and body fluids. The constraint and closure of the intestinal sweat pore are the main pathological basis of ulcerative colitis. According to the manifestations of colonoscopy, and the different etiological factors and pathogenesis that lead to the constraint and closure of sweat pore, there should be different treatment focuses such as expelling wind to open sweat pore, clearing fire to open sweat pore, promoting blood circulation to open sweat pore, for which wind-dispersing herbs, heat-clearing herbs, and blood-activating herbs are used accordingly. The method of retention enema can directly induce Chinese medicinal herbs to the affected part, so as to diffuse and unblock the sweat pore, regulate qi and blood, and thus restore the normal function of the intestinal sweat pore.

Journal of Neurogastroenterology and Motility 2025;31(1):75-85
Background/Aims:
Anti-reflux mucosal ablation (ARMA) is a promising endoscopic intervention for proton pump inhibitor (PPI)-dependent gastroesophageal reflux disease (GERD). However, the effect of ARMA on esophageal motility remains unclear.
Methods:
Twenty patients with PPI-dependent GERD receiving ARMA were prospectively enrolled. Comprehensive self-report symptom questionnaires, endoscopy, 24-hour impedance-pH monitoring, and high-resolution impedance manometry were performed and analyzed before and 3 months after ARMA.
Results:
All ARMA procedures were performed successfully. Symptom scores, including GerdQ (11.16 ± 2.67 to 9.11 ± 2.64, P = 0.026) and reflux symptom index (11.63 ± 5.62 to 6.11 ± 3.86, P = 0.001), improved significantly, while 13 patients (65%) reported discontinuation of PPI. Total acid exposure time (5.84 ± 4.63% to 2.83 ± 3.41%, P = 0.024) and number of reflux episodes (73.05 ± 19.34 to 37.55 ± 22.71, P < 0.001) decreased significantly after ARMA. Improved esophagogastric junction (EGJ) barrier function, including increased lower esophageal sphincter resting pressure (13.89 ± 10.78 mmHg to 21.68 ± 11.5 mmHg, P = 0.034), 4-second integrated relaxation pressure (5.75 ± 6.42 mmHg to 9.99 ± 5.89 mmHg, P = 0.020), and EGJ-contractile integral(16.42 ± 16.93 mmHg · cm to 31.95 ± 21.25 mmHg · cm, P = 0.016), were observed. Esophageal body contractility also increased significantly (distal contractile integral, 966.85 ± 845.84 mmHg · s · cm to 1198.8 ± 811.74 mmHg · s · cm, P = 0.023). Patients with symptom improvement had better pre-AMRA esophageal body contractility.
Conclusions
ARMA effectively improves symptoms and reflux burden, EGJ barrier function, and esophageal body contractility in patients with PPIdependent GERD during short-term evaluation. Longer follow-up to clarify the sustainability of ARMA is needed.

Background:
s/Aims: Sarcomatoid hepatocellular carcinoma (HCC) is a rare histological subtype of HCC characterized by extremely poor prognosis; however, its molecular characterization has not been elucidated.
Methods:
In this study, we conducted an integrated multiomics study of whole-exome sequencing, RNA-seq, spatial transcriptome, and immunohistochemical analyses of 28 paired sarcomatoid tumor components and conventional HCC components from 10 patients with sarcomatoid HCC, in order to identify frequently altered genes, infer the tumor subclonal architectures, track the genomic evolution, and delineate the transcriptional characteristics of sarcomatoid HCCs.
Results:
Our results showed that the sarcomatoid HCCs had poor prognosis. The sarcomatoid tumor components and the conventional HCC components were derived from common ancestors, mostly accessing similar mutational processes. Clonal phylogenies demonstrated branched tumor evolution during sarcomatoid HCC development and progression. TP53 mutation commonly occurred at tumor initiation, whereas ARID2 mutation often occurred later. Transcriptome analyses revealed the epithelial–mesenchymal transition (EMT) and hypoxic phenotype in sarcomatoid tumor components, which were confirmed by immunohistochemical staining. Moreover, we identified ARID2 mutations in 70% (7/10) of patients with sarcomatoid HCC but only 1–5% of patients with non-sarcomatoid HCC. Biofunctional investigations revealed that inactivating mutation of ARID2 contributes to HCC growth and metastasis and induces EMT in a hypoxic microenvironment.
Conclusions
We offer a comprehensive description of the molecular basis for sarcomatoid HCC, and identify genomic alteration (ARID2 mutation) together with the tumor microenvironment (hypoxic microenvironment), that may contribute to the formation of the sarcomatoid tumor component through EMT, leading to sarcomatoid HCC development and progression.
