OBJECTIVE To analyze the differences in chemical components of Gardenia jasminoides before and after processing with ginger, and to evaluate the quality differences among different producing areas. METHODS Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry was used to analyze the compositional differences of G. jasminoides before and after processing with ginger. The water content, total ash, and ethanol-soluble extract content of ginger- processed G. jasminoides were determined according to the 2020 edition of Chinese Pharmacopoeia. High performance liquid chromatography was adopted to determine the contents of genipin gentiobioside, geniposide, crocin Ⅰ and crocin Ⅱ in ginger- processed G. jasminoides. RESULTS A total of 49 chemical components were identified from raw G. jasminoides and ginger- processed G. jasminoides, including 14 flavonoids, 15 iridoids, 10 organic acids, 2 alkaloids and 8 other compounds. Among them, 42 components were detected in raw G. jasminoides, 28 in ginger-processed G. jasminoides, and 21 components were common to both. After processing with ginger, raw G. jasminoides lost 21 components (including iridoids, flavonoids, alkaloids, and others), while 7 chemical components were added (including coumarins, organic acids, organic acid esters, and flavonoids). For the 15 batches of ginger-processed G. jasminoides, the water content ranged from 5.64% to 7.11%, total ash from 2.92% to 4.87%, and ethanol-soluble extract from 40.61% to 58.02%. The average contents of genipin gentiobioside, geniposide, crocin Ⅰ and crocin Ⅱ were 0.108 7, 0.542 2, 0.565 0, and 0.012 5 mg/g, respectively. CONCLUSIONS After processing with ginger, G. jasminoides loses 21 components, while 7 new components are added. Differences are observed in the water content, total ash, ethanol-soluble extract, and the contents of genipin gentiobioside, geniposide, crocin Ⅰ, and crocin Ⅱ of ginger-processed G. jasminoides from different producing areas. Notably, samples from Fujian exhibit high contents of genipin gentiobioside and ethanol-soluble extract, while samples from Jiangxi have a high content of crocin Ⅰ.

BACKGROUND:Mitochondrial dysfunction is a key mechanism underlying the pathogenesis and progression of diabetic cystopathy.Recent studies have suggested that drugs targeting mitochondrial metabolism,oxidative stress,and apoptosis pathways can inhibit bladder tissue degeneration,offering novel therapeutic directions for diabetic cystopathy.OBJECTIVE:To explore the association between mitochondrial abnormalities and diabetic cystopathy and to summarize the mechanisms of pharmacological interventions targeting mitochondrial function.METHODS:The key words are"mitochondria,diabetes,diabetic cystopathy,diabetic bladder dysfunction,detrusor,urothelium,neuron,peripheral nerves"in Chinese and English.Relevant literature was retrieved from CNKI,WanFang,PubMed,and Web of Science.Selected articles were systematically screened and analyzed.RESULTS AND CONCLUSION:During the progression of diabetic cystopathy,mitochondria in detrusor muscle,urothelium,and peripheral nerve cells exhibit alterations in characterization,activity,function,and behavior.Under diabetic conditions,mitochondrial damage leads to increased reactive oxygen species production,increased cytochrome C release,reduced Bcl-2/Bax ratio,enhanced nuclear translocation of apoptosis-inducing factors,and activation of the poly(ADP-ribose)polymerase/c-Jun N-terminal kinase/mitochondrial apoptosis pathway.Mitochondria also act as damage-associated molecular patterns to regulate NLRP3,triggering inflammatory responses.Disrupted mitochondrial energy metabolism involves AMP-activated protein kinase/peroxisome proliferator-activated receptor gamma coactivator-1α signaling axis-mediated phenotypic changes,decreased levels of respiratory chain complexes Ⅰ,Ⅱ,andⅣ,impaired oxidative phosphorylation,inhibited tricarboxylic acid cycle,and reduced mitochondrial spare respiratory capacity.Novel therapeutic agents or formulations can ameliorate diabetic cystopathy by alleviating oxidative stress,exerting anti-inflammatory effects,and modulating energy-sensing pathways to restore mitochondrial function.Although mitochondrial roles in other diabetic complications have been extensively studied,research on their involvement in diabetic cystopathy remains insufficient and warrants further exploration.

Irritable bowel syndrome (IBS) is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years, traditional Chinese medicine (TCM) has made progress in multiple aspects of IBS research and treatment, including syndrome distribution, development of TCM formulas, clinical efficacy evaluation, external therapies, and psychosocial regulation. However, it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria, and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment, combining TCM external therapies such as acupuncture, moxibustion and acupoint application), and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies, artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas, so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

This paper proposes a two-stage method integrating visual foundation models (VFM) and diffusion models. The segment anything model (SAM) as VFM is combined with the SegRefiner diffusion model to construct the SAM-SegRefiner framework for automated segmentation of edema, inflammation, and thrombus regions in histopathological images of hemorrhoidal tissue, providing a reproducible technical tool for the objective quantification of pathological morphology and its application in traditional Chinese medicine (TCM) syndrome research. Trained and validated on multi-center retrospective data, the SAM-SegRefiner model achieved an average pixel accuracy of 95.32% and a mean intersection over union (mIoU) of 66.81% on an independent test set, significantly outperfor-ming comparative models such as U-Net, MixU-Net, and SAM-Med2D, and also demonstrating robust cross-center generalization capability. Furthermore, by correlating the quantitatively segmented results from the model with the patients' TCM syndrome types, the potential associations between pathomorphological features and TCM syndrome differentiation have been explored. The analysis revealed no statistically significant differences in the degree of inflammatory infiltration and thrombus formation among different syndrome types, suggesting a complex relationship between local pathological changes and systemic syndrome manifestations.

ObjectiveTo investigate whether modified Taohe Chengqitang (JTCT) treats liver fibrosis by inhibiting hepatic sinusoidal capillarization, and to verify whether its specific mechanism is related to the Homologous genes responsible for the notches along the edges of Drosophila wings(Notch) signaling pathway and endothelial nitric oxide synthase (eNOS) signaling pathway. MethodsFifty C57BL/6 mice were randomized into 5 groups: Control, model (5 mL·kg-1·3 d-1), low-dose JTCT, medium-dose JTCT, and high-dose JTCT (JTCT-L,JTCT-M,JTCT-H). Except the control group, the other groups were intraperitoneally injected with 20% carbon tetrachloride (CCl4) olive oil solution every 3 days for 4 weeks to induce liver fibrosis. Meanwhile, JTCT-L, JTCT-M, and JTCT-H groups were administrated with JTCT by gavage at doses of 16.6, 33.3, and 66.6 g·kg-1·d-1, respectively, for 4 consecutive weeks (the control and model groups received equal volumes of normal saline by gavage). Primary liver sinusoidal endothelial cells (LSECs) were isolated from rat livers through in situ perfusion of collagenase, Percoll density gradient centrifugation, and selective removal of Kupffer cells. After verification of cell phenotype, LSECs were used for experiments. For cells at the logarithmic growth phase, the small interfering RNA(siRNA) kit was used to knock down the expression of soluble guanylate cyclase (sGC) through transient transfection. Subsequently, the Notch agonist Jagged-1 was applied. Cell counting kit-8 (CCK-8) was used to examine the cytotoxicity of JTCT on LSECs. Real-time PCR and Western blot were employed to measure the expression of molecules in the Notch and eNOS signaling pathways at mRNA and protein levels, respectively. Intracellular Ca2+ was labeled with the fluorescent probe Fluo-4 acetoxymethyl ester(Fluo-4/AM). ResultsThe animal experiment showed that compared with the control group, the model group exhibited hepatic steatosis, inflammatory cell infiltration, hepatocyte degeneration and necrosis, lobular structural disorder, and fibrous tissue hyperplasia in the mouse liver tissue, significantly elevated serum levels of hydroxyproline (Hyp), alanine transaminase (ALT), and aspartate transaminase (AST) (P<0.01), significantly upregulated expression levels of Notch1, Hes family bHLH transcription factor 1(Hes1), Cluster of Differentiation 31(CD31), and von Willebrand factor(vWF) (P<0.01), and significantly downregulated phosphorylate(p)-eNOS/eNOS ratio and sGC expression (P<0.01). Compared with the model group, all the JTCT groups showed significantly reduced serum Hyp, ALT, and AST levels (P<0.01), downregulated expression of Notch1, Hes1, CD31, and vWF (P<0.05, P<0.01), and upregulated p-eNOS/eNOS ratio and sGC expression (P<0.05, P<0.01) in the liver tissue, with the JTCT-H group showing the most significant changes (P<0.01). The cell experiment showed that compared with the LSEC-1day group, the LSEC-5day group exhibited significantly increased expression of Notch1, Hes1, CD31, and vWF (P<0.01), significantly decreased p-eNOS/eNOS ratio and sGC expression (P<0.01), and elevated intracellular Ca2+ concentration (P<0.01). Compared with the LSEC-5day group, the JTCT group showed decreased expression of Notch1, Hes1, CD31, and vWF (P<0.01), significantly increased p-eNOS/eNOS ratio (P<0.01), and significantly reduced intracellular Ca2+ concentration (P<0.01). No significant differences were observed in the expression of Notch1, Hes1, eNOS, p-eNOS, CD31, vWF, sGC, or intracellular Ca2+ concentration between the Jagged1 group and the Jagged1+JTCT group. Compared with the LSEC-5day group, the sGC knockout group (sGC-KO) showed significantly increased expression of CD31 and vWF (P<0.01). There was no significant difference in CD31 or vWF expression between the sGC-KO group and the sGC-KO+JTCT group. ConclusionJTCT inhibits the activation of the Notch signaling pathway and restores the activity of the eNOS signaling pathway to suppress sinusoidal capillarization of LSECs, thereby treating liver fibrosis.
