Liver fibrosis is a critical pathological stage in the progression of various chronic liver diseases to liver cirrhosis and liver cancer， and it is characterized by the activation of hepatic stellate cells and excessive deposition of extracellular matrix. There are currently limited clinical treatment methods for liver fibrosis， and gene therapy has attracted increasing attention as a promising intervention strategy. Owing to its advantages of low immunogenicity， strong tissue tropism， and long-term gene expression， adeno-associated virus （AAV） has become an ideal vector for gene therapy. This article systematically reviews the structural and functional features of AAV， the tissue-targeting properties of different serotypes， and the methods for preparation and purification of recombinant AAV and focuses on the advances in the application of AAV-mediated gene overexpression， gene silencing， gene editing， and cellular reprogramming in mechanism research and intervention of liver fibrosis， as well as the challenges in clinical translation and corresponding strategies. AAV-mediated gene therapy is expected to provide novel tools and strategies for the precise treatment and mechanism study of liver fibrosis.

ObjectiveTo investigate the effect and molecular mechanism of exosomes derived from bone marrow mesenchymal stem cells（BMSC-exos） modified with Bushen Yisui capsule（BSYS）-containing serum on promoting the differentiation and maturation of OLN-93 oligodendrocytes by regulating miR-15b/Wnt signaling pathway. MethodsOLN-93 cells were divided into 5 groups， including the normal（NC） group， BMSC-exos group， BSYS-BMSC-exos group， BSYS-BMSC+LV-miR-15b-5p inhibitor-exos group， and BSYS-BMSC+LV-miR-15b-5p NC-exos group. DiR staining was used to observe the uptake of Exos by OLN-93 cells. The effective dosage of BSYS-BMSC-exos on OLN-93 cells was assessed by cell proliferation and activity assay（CCK-8）. Stable BMSCs lentiviral transfection strains were established to inhibit miR-15b-5p expression in both BMSCs and their exos， and transfection efficiency was verified by real-time fluorescent quantitative polymerase chain reaction（Real-time PCR） detection of miR-15b-5p. The expressions of 2′，3′-cyclic nucleotide 3′-phosphodiesterase（CNPase） and myelin proteolipid protein（PLP） in OLN-93 cells were detected by immunocytochemistry（ICC） and Western blot. The mRNA expressions of miR-15b-5p and Wnt3a in OLN-93 cells were detected by Real-time PCR， and the protein expression of Wnt3a was measured by Western blot. The expression levels of key molecules in the Wnt/β-catenin signaling pathway of OLN-93 cells， including glycogen synthase kinase（GSK）-3β， β-catenin， and T-cell specific transcription factor 4/transcription factor 7-like 2（TCF4/TCF7L2）， were measured by Real-time PCR and Western blot. ResultsDiR-labeled Exos were efficiently taken up by OLN-93 cells. The CCK-8 assay results indicated that 20 mg·L^-1 of BSYS-BMSC-exos exhibited the most significant effect in enhancing OLN-93 cell viability（P<0.01） and this dosage was selected for subsequent experiments. Following lentiviral transfection of BMSCs， Real-time PCR results revealed that miR-15b-5p was significantly suppressed in BMSCs（P<0.01）， and miR-15b-5p was also notably inhibited in BSYS-BMSC-exos（P<0.01）. ICC analysis further revealed an increase in the number of differentiated， mature CNPase and PLP-positive cells following BSYS-BMSC-exos treatment（P<0.01）. Western blot results demonstrated that the protein expression of CNPase and PLP was significantly enhanced with BSYS-BMSC-exos treatment（P<0.01）. Additionally， BSYS-BMSC-exos also increased the expression levels of miR-15b-5p and p-β-catenin proteins in OLN-93 cells， while decreased the mRNA and protein expressions of Wnt3a， as well as the mRNA expressions of β-catenin and TCF4/TCF7L2， and the protein expression level of p-GSK-3β（Ser9） was significantly reduced（P<0.05， P<0.01）. After the transfection of miR-15b-5p inhibitor into BSYS-BMSC-exos， the above effects were significantly diminished（P<0.05， P<0.01）. ConclusionBSYS-BMSC-exos facilitate the differentiation and maturation of OLN-93 cells， and its mechanism is related to the upregulation of miR-15b-5p in OLN-93 cells， which inhibits the expression of Wnt3a and thereby suppresses the Wnt signaling pathway.

ObjectiveTo investigate the intervention effects and mechanisms of the flavonoid hyperoside （Hyp） on lipopolysaccharide （LPS）-induced inflammation in the zebrafish model. MethodsZebrafish larvae were either microinjected with 0.5 g·L^-1 LPS or immersed in 1 g·L^-1 LPS for the modeling of inflammation. The larvae were then treated with Hyp at 25， 50， and 100 mg·L^-1 through immersion for four consecutive days. The inflammatory phenotypes were assessed by analyzing the mortality rate， malformation rate， body length， and yolk sac area ratio. Behavioral tests were conducted to evaluate the inflammatory stress responses， and macrophage migration was observed by fluorescence microscopy. Additionally， the mRNA levels of inflammation-related genes， including interleukin-1β （IL-1β）， interleukin-6 （IL-6）， chemokine C-C motif ligand 2 （CCL2）， chemokine C-X3-C motif receptor 1 （CX3CR1）， chemokine C-C motif receptor 2 （CCR2）， and genes associated with the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor-kappa B （NF-κB） signaling pathway， were measured by Real-time quantitative polymerase chain reaction（Real-time PCR）. ResultsCompared with the pure water injection group， the model group exhibited increased mortality， malformation rates and yolk sac area ratio （P0.01）， reduced body length （P0.01）， increased total swimming distance and high-speed swimming duration （P0.01）， and up-regulated mRNA levels of TLR4， MyD88， NF-κB， IL-1β， IL-6， CCL2， CX3CR1， and CCR2 （P0.01）. Hyp at low， medium and high doses， as well as aspirin， reduced the mortality and malformation rates （P0.05，P0.01）， increased the body length （P0.05，P0.01）， decreased the yolk sac area ratio （P0.01）， reduced the high-speed swimming duration （P0.01）， and down-regulated the mRNA levels of TLR4， MyD88， NF-κB， IL-1β， IL-6， CCL2， CX3CR1， and CCR2 （P0.05，P0.01） compared with the model group. ConclusionHyp may modulate the TLR4/MyD88/NF-κB pathway to ameliorate inflammatory phenotypes and alleviate stress conditions in zebrafish， thereby exerting the anti-inflammatory effect.

Urticarial vasculitis is a skin disease with urticaria-like lesions and a histopathological pattern of leukocytoclastic vasculitis. It is considered a "hidden rash" in traditional Chinese medicine. Xuanfu is the portal that regulates qi, blood, fluid, and the ascending, descending, exiting, and entering of nutrition qi and defensive qi. Collaterals are the pathways for the circulation of qi and blood. The two accompany each other, connecting zang-fu organs, reaching the surfaces of the skin, hair, and external body, circulating qi and fluid, and moistening and protecting the skin. Based on the theory of Xuanfu-collateral, this study aimed to clarify the etiology, pathogenesis, and treatment method of urticarial vasculitis. External assault by wind and Xuanfu blockage are believed to be the initiating factors of this disease. The malnutrition of Xuanfu and collaterals and accumulated dampness-heat are important links in the occurrence and development of urticarial vasculitis. It spreads from Xuanfu to the collaterals, and blockage of the collaterals is the immanent trend of this disease. Clinically, by closely adhering to the core pathogenesis of blockage of Xuanfu-collateral, treatment method such as using wind medicinals to open Xuanfu with pungent and dispersing properties, using the method of supplement deficiency and removing the blockage, and using medicinals to promote blood circulation and remove blood stasis to unblock the blocked collaterals. The herbs are flexibly added or subtracted to unblock Xuanfu and collaterals, harmonize qi and blood, thus all symptoms can be relieved. We hope that this study will provide new ideas for the treatment of urticarial vasculitis with traditional Chinese medicine.

This review summarizes the applications and advancements of artificial intelligence(AI)in the analysis of retinal vascular parameters. Retinal vascular parameters, including vessel diameter, fractal dimension, vascular tortuosity, branching angles, and vessel density, are important indicators for assessing changes in the retinal vascular network structure. These parameters are not only related to various ophthalmic diseases but also reflect the conditions of systemic diseases such as diabetes and Alzheimer's disease. This article provides a detailed discussion on the advantages of AI technology in the automated identification and quantification of retinal vascular parameters, particularly in improving measurement efficiency and accuracy, and enabling the early detection and monitoring of various diseases. Additionally, the challenges faced by AI in the analysis of retinal vascular parameters were discussed, such as data standardization and insufficient sample diversity, and proposes directions for future research. By thoroughly analyzing the application of AI in retinal vascular parameter analysis, this article aims to offer new perspectives and methods for clinical diagnosis and early intervention of diseases, holding significant clinical significance and application prospects.

Colorectal inflammatory cancer transformation poses a major risk to patients with colitis.Patients with chronic intestinal inflammation have an approximately 2-3 fold increased risk of developing colorectal cancer(CRC).Unfortunately,there is currently no effective intervention available.Huangqin decoction(HQD),a well-known traditional Chinese medicine(TCM)formula,is frequently clinically prescribed for treating patients with colitis,and its active ingredients have effective antitumour efficacy.Nonetheless,the mechanism of HQD-mediated prevention of colorectal inflammatory cancer transformation remains unclear.A strategy integrating metagenomic,lipidomic,and messenger RNA(mRNA)sequencing analysis was used to investigate the regulatory effects of HQD on the gut microbiome,metabolism and potential mechanisms involved in colorectal inflammatory cancer transformation.Our study revealed that HQD suppressed colorectal inflammatory cancer transformation,which was associated with enhanced in-testinal barrier function,decreased the inflammatory response,and regulation of the gut microbiome.Notably,cohousing experiments revealed that the transfer of the gut microbiome from HQD-treated mice largely inhibited the pathological transformation of colitis.Moreover,gut microbiome transfer from HQD-treated mice primarily resulted in the altered regulation of fatty acid metabolism,especially the remodeling of arachidonic acid metabolism,which was associated with the amelioration of pathological transformation.Arachidonic acid metabolism and the key metabolic enzyme arachidonic acid 12-lipoxygenase(ALOX12)were affected by HQD treatment,and no obvious protective effect of HQD was observed in Alox12-/-mice,which revealed that ALOX12 was a critical mediator of HQD protection against colorectal inflammatory cancer transformation.In summary,multiple omics analyses were applied to produce valuable data and theoretical support for the application of HQD as a promising intervention for the transformation of inflammatory CRC.

Objective:To explore the possibility of using a inferior gluteal artery perforator flap (IGAPF) for breast reconstruction in the patient who did not have suitable donor site in back and abdomen.Methods:In November 2024, a 25-year-old unmarried and childless woman with right breast cancer received immediate right breast reconstruction by a right free IGAPF after modified right mastectomy in the Department of Breast and Thyroid Surgery, Second Affiliated Hospital of Hainan Medical University. The locations of perforators were confirmed by both Multi-detector computed tomography angiography (MDCTA) and portable Doppler blood flow detector before surgery. The IGAPF was designed to take the inferior gluteal wrinkle as the lower edge, the axis of the flap was parallel to the inferior gluteal wrinkle, and the width of the flap was estimated where the incision could be directly closed. The size of right IGAPF was 6.0 cm×19.0 cm. Sharp dissection was performed between the sarcolemma and muscle fibres of gluteus, then the perforators were dissected along the direction of muscle fibres of gluteus. The vascular pedicle was kept at about 8.0 cm in length. The diameter of artery was about 2.0 mm and that for the veins was about 1.5 mm. End-to-end anastomoses with the right thoracodorsal artery and vein were successfully carried out. The donor site was directly closed, and it was hidden in the inferior gluteal wrinkle. Postoperative outpatient clinical review was made.Results:Pathological examination reported: an invasive carcinoma of right breast, axillary lymph node metastasis (2/10). The patient recovered well and the flap survived without any complication, i.e. ischemic necrosis, infection and haematoma. The patient was off-bed at 3 days and discharged at 13 days after surgery. At the 40 days of postoperative follow-up, the patient achieved a good recovery and the lower limb activity was not affected by the surgery. The patient was satisfied with the reconstructed breast and donor site recovery. The patient followed with scheduled chemotherapy and subsequent radiotherapy. The volume of reconstructed breast was smaller than the other breast, of which the patient was fully informed before the surgery.Conclusion:A free IGAPF provides an alternative donor sites for achieving a breast reconstruction due to the reliable pedicle vessels and invisible donor scars.
