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.

Objective: To explore the effects of Cldn14 gene knockout on renal metabolism and stone formation in rats，so as to provide reference for research in the field of urinary calium metabolism and stone formation. Methods: Cldn14 gene knockout homozygous rats and wild-type rats of the same age were randomly divided into 4 groups：wild-type control (WC) group，wild-type ethylene glycol (WE) group，gene knockout control (KC) group and gene knockout ethylene glycol (KE) group，with 10 rats in each group.The WE and KE groups were induced with ethylene glycol + ammonium chloride to form kidney stones，while the WC and KC groups received normal saline gavage.After 4 weeks of standard maintenance feeding，the urine samples were collected to detect the venous blood.The kidneys were collected for HE，Pizzolatto's staining and transmission electron microscopy.The protein in renal tissues was extracted to detect the expressions of Claudin16 and Claudin19. Results: Crystal deposition was observed in the renal tubular lumen of the WE and the KE groups，and more crystals were detected in the KE group.The WE group had a large number of intracytoplasmic black crystalline inclusions observed in renal tubular epithelial cells under transmission electron microscope，followed by the KE and KC groups.Compared with WC and WE groups，KC and KE groups had significantly decreased serum calcium and magnesium levels but significantly increased urinary calcium level.In addition，the urinary calcium level was higher in the WE group than in the WC group and higher in the KE group than in the KC group.The KE group had lower level of Claudin16，but there was no significant difference in the level of Claudin19 among the 4 groups(P>0.05). Conclusion: Knockout of Cldn14 gene alone cannot effectively reduce urinary calcium excretion or reduce the risk of stone formation in rats，which may be related to the decrease of Claudin16 level.

Objective:To evaluate the feasibility, safety and effects of tumor resection in the anterior space of the styloid process via transoral endoscopic medial parapterygomandibular ligament approach. Methods:This retrospective study included 24 patients who were diagnosed with tumors in the anterior space of the styloid process and treated with the transoral endoscopic medial parapterygomandibular ligament approach. Twenty-four patients who underwent surgery by traditional approach were selected on a 1∶1 ratio as control group. We compared the en bloc resection rate, the operation time, amount of blood loss, the postoperative pain VAS score, recurrence rate, length of hospital stay, complication rate between the two groups. Results:Among the 24 patients, pleomorphic adenoma was confirmed in 18 cases （75.0%）, basal cell adenoma in 2 cases （8.3%）, and neurilemmoma in 4 cases （16.7%）. In the transoral endoscopic group, the en bloc resection rate was 91.7%, the maximum tumor diameter was （42.2±12.2） mm, the operative time was （117.9±29.8）min, the blood loss was （36.7±18.7） mL, the postoperative pain VAS score （1.5±0.7）, no recurrence was observed, length of hospital stay was （10.8±2.9） d. Wound dehiscence occurred in one case in the transoral endoscopic group, and no other postoperative complication was observed. There were significant differences in the operation time, blood loss, the postoperative pain VAS score between the two groups, while no difference was found in gender, age, en bloc resection rate and length of hospital stay. Conclusion:The tumor resection in the anterior space of the styloid process via transoral endoscopic medial parapterygomandibular ligament approach was safe, minimally invasive and feasible.

Xiaohuang Qudan decoction (XHQDD) is a classical traditional Chinese medicine (TCM) formula widely used in the treatment of cholestatic liver injury. Despite its widespread use, the protective mechanism of XHQDD against cholestatic liver injury remains incompletely understood. The aim of this study was to investigate whether XHQDD mediates its beneficial effects by inhibiting the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) pathway and regulating TH17/Treg balance. To this end, the researchers used Sprague-Dawley (SD) rats and established a cholestatic liver injury model by oral administration of alpha-naphthylisothiocyanate (ANIT). The experimental group was divided into six groups: Control (CON), ANIT, ursodeoxycholic acid (UDCA), XHQDD-low dose (XHQDD-L) group, XHQDD-medium dose (XHQDD-M) group, and XHQDD-high dose (XHQDD-H) groups. Then, after 7 d of treatment, various tests were performed to verify the results. Firstly, XHQDD and its drug-containing serum were analyzed by ultra-high performance liquid chromatography-mass spectrometry/mass spectrometry (UPLC-MS/MS), and 14 blood-entry components were identified. Then, bile flow was monitored and found to be significantly reduced in the model group, which was significantly reversed in the UDCA and XHQDD groups. To further assess ANIT-induced liver injury, hematoxylin and eosin (H&E) and Sirius red staining, alongside transmission electron microscopy (TEM), were employed to observe liver tissues, revealing hepatocellular injury, cholestasis, and hepatic fibrotic changes. Serum inflammatory factors and liver injury indicators were assessed using enzyme-linked immunosorbent assay (ELISA), indicating an inflammatory state in ANIT-induced liver injury rats. The expression levels of JAK2/STAT3-related genes and proteins in liver and intestinal tissues were measured via quantitative reverse transcription polymerase chain reaction (qRT-PCR), immunohistochemistry, immunofluorescence (IF) staining, and Western blottting (WB) assays. These studies revealed that the inflammatory state of liver-injured rats was inextricably linked to the inflammatory cascade associated with the JAK2/STAT3 pathway and that XHQDD may exert anti-inflammatory efficacy by inhibiting the JAK2/STAT3 pathway. Flow cytometry was used to determine the percentage of T helper 17 (Th17)/regulatory T (Treg) cells in serum and hepatocytes, and it was further found that XHQDD was able to regulate Th17/Treg immune homeostasis in liver-injured rats. The findings suggest that XHQDD markedly alleviates inflammation in ANIT rats, potentially treating cholestasis and liver injury through JAK2/STAT3 inhibition and Th17/Treg balance regulation.

And there was no significant difference in the contents of ellagic acid and kaempferol 3-O-glucoside before and after irradiation. The similarity of fingerprints before and after irradiation was between 0.995 and 1.000. CONCLUSION Irradiation can effectively control the microbial level in Rubus chingii Hu, and there is no significant effect on the chemical composition of Rubus chingii Hu, the results provide a basis for the application of irradiation in the sterilization process of Rubus chingii Hu.

OBJECTIVE To evaluate the quality and existing problems of Compound Paracetamol and Chlorphenamine Tablets for Infant. METHODS Using legal standards to inspect sampled samples, and several analytical methods were subsequently established or improved for the exploratory research on related substances, assay, dissolution, subdivision characteristics of scored tablets, and genotoxic impurities. RESULTS All samples met the regulatory specification, and the pass rate was 100%. However, the control for related substances was lacking, and the method for assay and content uniformity was defective. The exploratory studies showed that the assay and content uniformity met the requirements, and the risk of related substances and genotoxic impurities was acceptable. As a divisible tablet, the subdivision characteristics could not meet the requirements of the scored tablet, and the dissolution performance of some enterprise samples could not meet the requirements of similar products in foreign pharmacopoeias. CONCLUSION The overall quality of this product is adequate. However, due to the early time on the market, some quality attributes no longer meet the requirements of current regulations or relevant guidelines. The manufacturers should further optimize the prescription and production process, referring to foreign similar products. The current specification needs to be revised and improved.

The minimal persistent inflammation(MPI)of allergic rhinitis(AR)is asymptomatic inflammation that occurs locally in the nasal mucosa after exposure to low doses of allergens.With the study of MPI,researchers have realized that this local sub-clinical inflammation in patients with AR not only causes chronic damage to the nasal mucosa,but also increases the hypersensitivity and hyperresponsiveness of allergic airway disease.The concept of MPI has changed our strategy for the treatment of AR,which re-quires that we should not only intervene in the symptomatic exacerbation period,but also intervene in the asymptomatic MPI period.This article systematically reviews the immunological mechanism,adverse effects,and treatment strategies of the MPI,to provide bet-ter treatment for the MPI of AR and reduce the recurrence of AR.

Objective To explore the application value of compressed sensing(CS)contrast enhanced 3D fluid attenuated inver-sion recovery(FLAIR)in the detection of tumor brain metastases.Methods Sixty patients with malignant tumors who underwent head MRI enhancement examination were selected.Routine plain scan and contrast enhanced 3D T1 WI were performed first,and CS 3D FLAIR scan was performed 5 min after contrast agent injection.The image quality were graded and the number of lesions were summarized by two senior radiologists.The contrast-to-noise ratio(CNR)of lesions greater than 5 mm was measured.SPSS 22.0 was used for Kruskal-Wallis(H),Mann-Whitney U rank sum and paired t-test analysis,and P＜0.05 was significant difference.Results There were no significant differences in image quality among the 3 sequences(H=3.843,P=0.416).Among 121 brain metastases(n=32),there were 89 lesions detected by routine plain scan,103 lesions detected by contrast enhanced 3D T1WI,and 112 lesions detected by CS 3D FLAIR.Overall comparison of number of lesions with different sizes detected by three sequences was significant difference(H=88.421,P＜0.05).There were statistically significant differences between CS 3D FLAIR and routine plain scan and contrast enhanced 3D T1 WI,respectively(P＜0.05).Conclusion Contrast enhanced 3D FLAIR can better display tumor brain metastases and small metastases in brain parenchy-ma and improve the diagnostic accuracy of brain metastases.Combined with CS technology,it improves scanning speed,which has important clinical value for diagnosing and treat the malignancy.
