AIM: To evaluate the reliability of a digital multimedia system for measuring near-distance horizontal heterophoria.METHODS: This cross-sectional diagnostic study enrolled patients with refractive errors who visited Shantou Aier Eye Hospital from May 2023 to August 2025, presenting with symptoms of visual fatigue, undergoing myopia management, or receiving routine ophthalmic examinations, and who completed heterophoria testing during this period. All patients wearing full refractive correction underwent near-distance(0.4 m)horizontal heterophoria measurement in a random order using the digital multimedia system, the Von Graefe method, and the Maddox rod method. Two consecutive measurements were performed for each method. The intraclass correlation coefficient(ICC)was used to analyze the measurement repeatability of each method, and Bland-Altman analysis and Spearman correlation analysis were employed to evaluate the consistency between the digital multimedia system and the two traditional methods.RESULTS: A total of 60 patients(120 eyes)were included, comprising 27 males and 33 females, with a mean age of 21.03±7.24 y. Repeatability analysis showed that the ICC for the digital multimedia system was 0.960(95%CI: 0.934-0.976), for the Von Graefe method was 0.979(95%CI: 0.964-0.987), and for the Maddox rod method was 0.956(95%CI: 0.926-0.973), all indicating excellent repeatability. Bland-Altman analysis revealed a mean difference of 0.367△ [95% limits of agreement(LoA): -2.97△ to 3.70△] between the Von Graefe method and the digital system, and a mean difference of 0.067△(95% LoA: -3.05△ to 3.19△)between the Maddox rod method and the digital system. Both differences were within the clinically acceptable range(difference <4△). Spearman correlation analysis showed positive correlations between the digital system and the Von Graefe method(rs=0.867)and between the digital system and the Maddox rod method(rs=0.777, all P<0.001).CONCLUSION: The digital multimedia system demonstrates high repeatability and good consistency with the traditional Von Graefe and Maddox rod methods for measuring near-distance horizontal heterophoria. It shows promise as a new and effective tool for clinical near-distance horizontal heterophoria measurement.

Intravitreal anti-vascular endothelial growth factor(anti-VEGF)therapy has been widely used, but the variability in its therapeutic efficacy limits individualized treatment. In recent years, the application of artificial intelligence(AI)has opened up new avenues for personalized treatment response prediction, and its core branches include machine learning(ML)and deep learning(DL). This review systematically retrieved and analyzed 41 relevant studies published up to April 2025. Comprehensive analysis reveals that AI predictive models are evolving from forecasting single endpoints(such as visual acuity or central retinal thickness)to integrating multi-dimensional endpoints(encompassing anatomical, functional, and treatment demand parameters)and generating predictive imaging outputs. In terms of technical approaches, DL models(28 studies, accounting for 68.3%)dominate this field due to their robust image interpretation capabilities, while ML models(10 studies, 24.4%)retain significant value in the analysis of structured clinical data. Cross-disease comparisons indicate that research efforts are most concentrated on age-related macular degeneration(ARMD)and diabetic macular edema(DME), with shared conceptual frameworks for model construction, yet distinct anatomical and functional indicators are prioritized for each disease. Currently, the field confronts several key challenges, including insufficient prospective clinical validation, limited model interpretability(the “black box problem”), and a scarcity of high-quality multi-center datasets. Moving forward, it is imperative to advance real-world validation and develop explainable AI techniques to expedite the clinical translation of these predictive models.

ObjectiveTo explore the mechanism by which Qijia Rougan decoction ameliorates liver fibrosis through amino acid/fatty acid metabolic reprogramming and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway, based on the miRNA-mRNA regulatory network and the interaction between metabolism and signaling pathways. MethodsSprague-Dawley (SD) rats were randomized into four groups (n=8): control, model, and low-dose and high-dose (7.0, 28.0 g·kg-1·d-1, respectively) Qijia Rougan decoction. Liver fibrosis was induced by subcutaneous injection of carbon tetrachloride (CCl4). From week 9, drug intervention was implemented for 7 weeks. After the final administration, the pathological changes in the liver were evaluated through hematoxylin-eosin (HE) and picrosirius red (PSR) staining. An automated biochemical analyzer was used to measure the serum levels of biochemical indicators, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bile acid (TBA), albumin (ALB), and cholesterol (TC). High-throughput miRNA sequencing was performed to identify differentially expressed miRNAs (DemiRs) during liver fibrosis. A miRNA-mRNA interaction network was constructed to identify key targets, which were then subjected to GO and KEGG enrichment analyses. The expression levels of selected DemiRs were validated by Real-time PCR. ResultsCompared with the control group, the model group showed marked hepatic lobular necrosis, increased collagen deposition, significant fibrosis, elevated serum levels of ALT, AST, ALP, and TBA (P<0.01), and declined levels of ALB and TC (P<0.01). Compared with the model group, Qijia Rougan decoction treatment reduced hepatic necrosis, collagen accumulation, and fibrosis, lowered the serum levels of ALT, AST, ALP, and TBA (P<0.01), and raised the levels of ALB and TC (P<0.01). Integrated miRNA-seq and RNA-seq analysis identified 31 DemiRs (6 upregulated and 25 downregulated) and 498 targets. The expression trends of four selected DemiRs, including rno-miRNA-376b-3p, were consistent with sequencing results (R2=0.93). Functional annotation revealed that top 20 upregulated targets were enriched in amino acid and fatty acid metabolism, while top 20 downregulated targets were significantly associated with the PI3K/Akt signaling pathway and cancer progression. ConclusionQijia Rougan decoction alleviates liver fibrosis by reconstructing the miRNA-mRNA regulatory network, promoting metabolic reprogramming, and inhibiting the PI3K/Akt signaling pathway. These findings provide mechanism evidence supporting the multi-targeted antifibrotic effects of traditional Chinese medicine compound formulas.

Objective To develop albumin-binding indocyanine green (ICG) and assess its potential for near-infrared fluorescence imaging and intraoperative navigation in lung cancer. Methods ABD-tri was recombinantly expressed by genetic engineering. Its albumin-binding capability was determined using size-exclusion chromatography, and its albumin-dependent binding to lung cancer cells was evaluated by flow cytometry. ICG was conjugated to ABD-tri to generate the fluorescent probe ABD-tri-ICG. The potential of ABD-tri-ICG for near-infrared fluorescence imaging and imaging-guided tumor resection was evaluated in mice bearing subcutaneous tumor grafts of lung cancer. Results ABD-tri was highly expressed in Escherichia coli (E. coli) and was purified to homogeneity via a simple affinity chromatography. ABD-tri bound both human and murine serum albumin, contributing to its binding to lung cancer cells. ICG was effectively conjugated to ABD-tri to produce the fluorescence probe ABD-tri-ICG after mixing and incubation at room temperature for 1 h. In mice bearing lung cancer tumor grafts, intravenously injected ABD-tri-ICG enabled clear visualization of tumors with diameters ranging from 5 to 7 mm within 0.5-24 h post-injection. The tumor grafts were resected under the guidance of ABD-tri-ICG-mediated near-infrared fluorescence imaging. Conclusion Intravenous injection of ABD-tri-ICG allows rapid and sustained visualization of lung cancer tumor grafts and enables intraoperative navigation in mice, warranting further evaluation on the clinical translation of ABD-tri-ICG.

Objective: To evaluate the methodological quality and reporting quality of clinical practice guidelines or expert consensus on blood transfusion and blood use (BTBU) in China (hereinafter referred to as "guidelines/consensus"), providing reference for the development and updating of future BTBU guidelines/consensus. Methods: A systematic search was conducted in Chinese databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Data-base, relevant guideline release platforms, and professional association websites. BTBU-related guidelines/consensus published between January 2006 and December 2025 were included. According to the inclusion and exclusion criteria, after completing literature screening and data extraction, three evaluators independently assessed the quality of the included literature using the Scientificity, Transparency, and Applicability of Guidelines Rating Tool (STAR), the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), and the International Practice Guideline Reporting Standards (RIGHT). Results: A total of 29 documents were included, including 5 guidelines, 22 consensus statements, and 2 protocols. The results of the STAR assessment showed that the total score was (21.7±8.8)%. The domain score ratios for registration, research protocol, funding, working group, conflict of interest, clinical question, evidence, consensus method, recommendation, accessibility and other domains were (2.2±12.1)%, 0, (36.7±25.1)%, (18.3±7.6)%, (19.2±15.3)%, (16.6±23.1)%, (15.1±6.3)%, (9.6±21.2)%, (54.3±18.4)%, (31.7±10.4)% and (10.3±31.0)%, respectively. For the AGREE Ⅱ assessment, the methodological quality of 26 articles was rated Grade B and 3 articles Grade C. The results of the RIGHT assessment indicated that the overall reporting rate of all guidelines/consensuses was (65.3±4.0)%. Conclusion: The methodological and reporting quality of current expert guidelines/consensus on BTBU in China still need improvement, and guidelines and consensus should be strictly formulated and standardized according to the standards of STAR, AGREE II and RIGHT.

ObjectiveTo address the challenge of balancing efficiency and purity in isolating MSCs from rat thoracic aorta using traditional methods and to establish and validate an optimized isolation and culture system based on the dual-phase harvesting method. MethodsThoracic aortas were aseptically isolated from 3 to 4-week-old SD rats and minced. Three experimental groups were included: simple enzymatic digestion, pre-explant-enzymatic digestion sequential method, and the dual-phase harvesting method. Growth kinetic parameters, including time to initial cell migration, time to primary confluence, and cell yield, were systematically compared among the three groups. Passage‑4 cells were examined for surface marker expression (CD73, CD44, CD29, CD45, CD34, and CD11b/c) by flow cytometry. Their stemness was evaluated through osteogenic, adipogenic, and chondrogenic trilineage differentiation assays. ResultsThe time to primary confluence in the dual-phase harvesting method group (8.5 ± 1.0 ) d was significantly shorter than that of the simple enzymatic digestion group (11.2±1.2) d and the pre‑explant enzymatic digestion sequential group (12.8±1.5) d. Flow cytometric analysis revealed that the harvested cells consistently showed high expression of CD73 (87.2±1.5)%, CD44 (87.1±0.8)%, and CD29 (96.8±1.3)%, with low expression of CD45 (3.22±0.2)%, CD34 (2.46±0.5)%, and CD11b/c (2.53±2.1)%. Upon directed induction, the cells formed Alizarin Red‑positive calcium nodules, Oil Red O‑positive lipid droplets, and Alcian Blue-positive glycosaminoglycans, confirming complete trilineage differentiation potential. The cells could be stably expanded to passage 8 while maintaining a uniform elongated spindle-shaped morphology. ConclusionThe dual‑phase harvesting method established in this study is an efficient and stable optimized protocol for isolating MSCs from the rat thoracic aorta media. This approach synergistically enhances cell yield, purity, and stemness through its temporally designed two‑step process, thereby providing a high-quality in situ cell source for vascular biology research and regenerative medicine.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

Human keratinocyte growth factor-1 (hKGF-1), a member of the fibroblast growth factor (FGF) family, plays crucial roles in organ development, cell proliferation, wound healing, and tissue repair, representing one of the most effective and specific growth factors for skin repair. However, obtaining recombinant hKGF-1 remains challenging due to its universally low expression efficiency in vitro. This study employs the Bombyx mori baculovirus expression system to establish a technological platform that utilizes the economically important insect Bombyx mori as a bioreactor for high-efficiency and low-cost expression and production of recombinant human keratinocyte growth factor 1 (hKGF-1) protein, ultimately achieving high-level expression of hKGF-1 in Bombyx mori ovary cell line (BmN). In this study, we optimized the hKGF-1 sequence based on the codon preference of baculovirus. By fusing hKGF-1 with polyhedrin (highly expressed in this system) and adding extra promoters and enhancers, we significantly improved the expreesion level of hKGF-1 in Bombyx mori cells. The results demonstrated that the aforementioned strategies significantly enhanced the expression level of hKGF-1 in Bombyx mori cells. SDS-PAGE and Western blotting results revealed that the highest hKGF-1 expression (accounting for 8.7% of total cellular protein) was achieved when the Polh promoter was combined in tandem with the P6.9 promoter and hKGF-1 was fused with a 15-residue polyhedrin fragment for co-expression. The optimal harvest time was determined to be 120 h post transfection. This study achieved the efficient expression of hKGF-1 in Bombyx mori cells, establishing an ideal technological platform for the industrial utilization of recombinant hKGF-1. The developed methodology not only provides valuable technical references for the production of other growth factors and complex proteins, but also demonstrates significant implications for employing silkworms as bioreactors for recombinant human protein expression.

Bombyx mori nucleopolyhedrovirus (BmNPV) is extremely harmful to the silk industry. The polyhedrin, which encodes the polyhedrin (Polh), can be expressed at ultra-high levels and form occlusion bodies in the nucleus, embedding the progeny virus within it. However, the detailed mechanism by which polyhedrin is transported into the host cell nucleus remains unknown. Clarifying the nuclear import mechanisms of viral proteins can help us develop better prevention and treatment measures against baculoviruses. This study employed molecular cloning, co-immunoprecipitation, and immunofluorescence to analyze in detail the expression pattern of the highly expressed polyhedrin in the very late stage of the virus, and further revealed that the host protein importin α participates in the nuclear import of polyhedrin through protein interactions. This study provides a reference for further elucidating the nuclear import mechanisms of the baculovirus proteins including polyhedrin that can enter the nucleus.

Objective:To investigate the efficacy and safety of R0 surgery combined with PARP inhibitors in the treatment of advanced epithelial ovarian cancer in 52 patients.Methods:A retrospective analysis was performed on 104 patients with International Federation of Gynecology and Obstetrics Ⅲ-Ⅳ epithelial ovarian cancer who received treatment at the Department of Gynecology and Obstetrics, Xinhua Hospital, Huainan Xinhua Medical Group from January 2021 to December 2023. The patients were divided into a control group and an observation group ( n = 52/group). Patients in the control group underwent non-R0 surgery followed by six cycles of chemotherapy with platinum and paclitaxel, along with maintenance therapy using olaparib or niraparib. Patients in the observation group underwent R0 surgery followed by the same chemotherapy and maintenance therapy as those in the control group. Comparisons were made between the two groups regarding general data, perioperative conditions, and postoperative levels of cancer antigen 125, human epididymis protein 4, vascular endothelial growth factor, interleukin-15, gamma interferon, and recurrence rates measured within 1 year after chemotherapy. Results:There was no statistically significant difference in age, underlying diseases, or pathological types according to International Federation of Gynecology and Obstetrics staging between the two groups (all P > 0.05). However, compared with the control group, the observation group had a longer surgical time [(290.17 ± 36.72) minutes vs. (206.58 ± 22.57) minutes, t = 171.20, P < 0.001]. The intraoperative blood loss in the observation group was significantly greater than that in the control group [(800.44 ± 134.22) mL vs. (743.16 ± 87.85) mL, t = 1 094.00, P = 0.003]. The interval between surgery and the start of chemotherapy in the observation group was longer than that in the control group [(13.00 ± 0.94) days vs.(12.04 ± 0.92) days, t = 3.07, P < 0.001]. There was no statistically significant difference in postoperative complications ( P > 0.05). Compared with the control group, the observation group had lower levels of cancer antigen 125 [(14.27 ± 2.16) IU/mL vs. (188.57 ± 30.74) IU/mL, t = 40.794, P < 0.001], human epididymis protein 4 [(25.29 ± 2.49) pmol/L vs. (74.21 ± 0.52) pmol/L, t = 138.68, P < 0.001], vascular endothelial growth factor [(23.70 ± 3.01) ng/mL vs. (51.66 ± 4.67) ng/mL, t = 36.28, P < 0.001], and recurrence rate [17.30% (9/52) vs. 88.46% (46/52), χ2 = 52.83, P < 0.001]. Compared with the control group, the observation group showed higher levels of interleukin-15 [(57.36 ± 9.48) pg/mL vs. (24.24 ± 4.04) pg/mL, t = -23.17, P < 0.001] and gamma interferon [(50.16 ± 4.43) pg/mK vs. (12.99 ± 1.30) pg/mL, t = -763.17, P < 0.001]. Conclusions:R0 surgery is effective and safe. R0 surgery followed by maintenance therapy with PARP inhibitors can significantly improve chemotherapy outcomes and delay tumor recurrence in patients with advanced epithelial ovarian cancer non-R0 surgery combined with chemotherapy plus maintenance therapy with PARP inhibitors.
