Cirrhotic portal hypertension is a clinical syndrome caused by persistently elevated portal venous pressure due to liver cirrhosis and can lead to a series of complications, among which esophagogastric variceal bleeding has become one of the most severe complications due to sudden onset and a high mortality rate. Since the release of Expert consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension (2019 edition), significant advances have been achieved in this field in China and globally. In order to formulate an expert consensus aligned with the situation of China, Chinese Society of Surgery, Chinese Medical Association organized and compiled Expert Consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension (2025 edition). This article elaborates on the key updates in the new edition and explores the major differences between the old and new editions, in order to enhance the understanding of the new edition among clinicians and provide a reference for clinicians in clinical work.

Driven by policy initiatives promoting the integration of digital-intelligent technologies with primary healthcare and the digital transformation of traditional Chinese medicine (TCM), Smart TCM has emerged as a pivotal strategy for enhancing primary healthcare services for major chronic diseases. This paper reviews the current status, challenges, and feasible pathways of Smart TCM in community-level management of cardiovascular–cerebrovascular diseases and tumors, which represent major chronic disease burdens. Our findings indicate that Smart TCM demonstrates emerging potential in primary healthcare for chronic diseases across the entire continuum of “prevention-screening-diagnosis-treatment-management.” However, several significant challenges persist, including data silos and security vulnerabilities, limited applicability of existing models to real-world clinical needs, and insufficient digital literacy among primary healthcare physicians and elderly patients. To address these constraints, this paper proposes a multidimensional strategy encompassing the development of secure and interoperable regional data platforms, lightweight intelligent devices and support services aligned with primary care capacity, unified technical and data standards with corresponding quality control systems, adaptive and dynamically updated artificial intelligent models, interdisciplinary workforce training and patient education programs, and enhanced policy and health insurance support. Overall, Smart TCM shows great promise for improving the efficiency of primary healthcare delivery and establishing innovative TCM-based chronic disease management paradigms.

ObjectiveTo systematically clarify the expression profile of splicing factor 3B subunit 6 (SF3B6) in pancreatic cancer, its clinical prognostic value, and its regulatory effect on the malignant phenotype of cancer cells through bioinformatics analysis, clinical sample validation, and in vitro functional experiments, and to assess its potential as a novel tumor biomarker. MethodsTranscriptomic and clinical data were downloaded from The Cancer Genome Atlas and Xena public databases at The University of California Santa Cruz to investigate the difference in the expression of SF3B6 between pancreatic cancer tissue and normal pancreatic tissue, and the association of SF3B6 with the prognosis and clinical indices of patients with pancreatic cancer was analyzed. Three pancreatic ductal adenocarcinoma cell lines and one normal pancreatic ductal epithelial cell line were cultured, and RT-qPCR was used to measure the expression level of SF3B6 in pancreatic cancer. A total of 43 patients with pancreatic cancer who underwent surgery in Binzhou Medical University Hospital from January 2024 to December 2025 were enrolled as subjects, and Western blot and RT-qPCR were used to measure the expression of SF3B6 in pancreatic cancer tissue. Based on the median expression level of SF3B6 measured by RT-qPCR, the patients were divided into high and low expression groups. The association of SF3B6 expression with clinical features and prognosis was assessed. A pancreatic cancer cell line with stable low SF3B6 expression was constructed, and CCK-8 assay and Transwell migration and invasion assays were used to observe the impact of SF3B6 on the biological behaviors of the pancreatic cancer cell line, including proliferation, migration, and invasion. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and a one-way analysis of variance was used for comparison between multiple groups, while the least significant difference t-test or the Games-Howell test was used for further comparison between two groups; the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test was used for comparison of categorical data between two groups. A Logistic regression analysis was used to investigate the influencing factors for the expression of SF3B6, and the univariate and multivariate Cox proportional-hazards regression model analyses were used to investigate the risk factors for prognosis. ResultsThe bioinformatics analysis showed that SF3B6 was highly expressed in pancreatic cancer tissue (P<2.2×10-16) and significantly affected the overall survival (P=0.011) and progression-free survival (P=0.002) of patients with pancreatic cancer. Sex, age, clinical stage, and TNM stage were not influencing factors for SF3B6 expression (all P>0.05), and SF3B6 could be used as an independent risk factor for the survival outcome of patients with pancreatic cancer (overall survival: hazard ratio=2.26, 95% confidence interval: 1.13 — 4.50, P=0.021; progression-free survival: hazard ratio=2.37,95% confidence interval: 1.22 — 4.58, P=0.010). Cellular and tissue experiments confirmed the high expression level of SF3B6 in pancreatic cancer cell lines (P<0.05), and the expression level of SF3B6 increased with the increase in the malignancy of pancreatic cancer, showing the highest relative expression level in PANC-1 cells with the highest degree of malignancy; the expression level of SF3B6 in the solid tissue of pancreatic cancer was significantly higher than that in paracancerous tissue (P<0.01). The expression level of SF3B6 might affect the overall survival of patients with pancreatic cancer (P<0.05), while it showed no significant association with age, sex, pathological grade, maximum tumor diameter, or clinical stage (all P>0.05). Knockdown of SF3B6 significantly inhibited the proliferation, migration, and invasion of pancreatic cancer cells (all P<0.01). ConclusionSF3B6 is highly expressed in pancreatic cancer, and the high expression of SF3B6 can promote the proliferation, migration, and invasion of pancreatic cancer cells. Therefore, SF3B6 can be used as a potential biomarker for prognostic evaluation.

The retina has a complex and delicate function and structure, containing a large number of neuronal cells with extremely limited regenerative capacity, which are susceptible to damage and apoptosis under pathological conditions such as ischemia and hypoxia, resulting in irreversible vision loss. Retinal diseases are very common, such as retinitis pigmentosa(RP), age-related macular degeneration(ARMD), diabetic retinopathy(DR), and glaucoma. Most of the diseases in this category are treated symptomatically, which is effective but has some limitations in neuroprotection. Vascular endothelial growth factor(VEGF)-B is functionally relatively inert in the VEGF family, and unlike pro-angiogenic VEGF-A, VEGF-B shows functional inertia in angiogenesis but exhibits significant neuroprotective effects. VEGF-B is a potent anti-apoptotic, antioxidant factor that can regulate the expression of apoptotic genes and enhance the expression of glutamic acid decarboxylase 1 by binding to VEGFR-1 to activate the ERK1/2 or Akt pathway, in addition to decreasing the expression of glutamate, resulting in retinal neuroprotective effects. In this article, the protective effects of VEGF-B on retinal neuronal cells were reviewed to provide new ideas for the treatment of retina-associated diseases.

Phacoemulsification with intraocular lens implantation(Phaco+lOL)has become the main treatment for cataracts due to small incision and fast recovery. Phacoemulsification can damage the conjunctiva, cornea and other ocular surface tissues, causing local inflammation, which in turn leads to eye dryness and discomfort after surgery. According to studies, patients who suffer from phacoemulsification most experience dry eye syndrome within 24 h, which gradually worsens and reaches its peak in the following 1 wk, seriously affecting their quality of life. The review aims to comprehensively investigate the effects of preoperative patient physical conditions and local ocular status, intraoperative maneuvers and postoperative treatments on postoperative dry eye, with the expectation of formulating scientific and effective preventive measures for potential dry eye patients after phacoemulsification, and providing a theoretical basis for postoperative dry eye treatment.

AIM: To assess the impact of optimized pulsed technology(OPT)on the morphological and functional changes of meibomian glands in patients with meibomian gland dysfunction(MGD).METHODS: This prospective case-control study enrolled 60 MGD patients(60 right eyes)treated at Weifang Eye Hospital from September 2023 to February 2024. Patients were categorized into mild, moderate, and severe groups based on the extent of meibomian gland loss, with 20 cases(20 eyes)per group. Treatments consisted of bilateral OPT combined with meibomian gland massages, administered biweekly over four sessions. Ocular surface function indicators including the ocular surface disease index(OSDI), corneal fluorescein staining(CFS), non-invasive average tear break-up time(NIBUTav), and non-invasive tear meniscus height(NITMH), as well as meibomian gland function parameters such as meibomian gland expressibility score(MGES)and meibomian gland secretion score(MGYSS)were observed and recorded before treatment and at 3 mo after final treatment. Cellular-level assessments using in vivo confocal microscopy(IVCM)examined meibomian gland acinar unit density(MGAUD), inflammatory cell density(ICD), meibomian gland acinar longest diameter(MGALD)and meibomian gland acinar shortest diameter(MGASD).RESULTS: At baseline, no significant differences were found in NITMH across groups(P>0.05). Statistical significance were observed in NIBUTav, MGES, MGYSS, MGAUD, MGALD, and MGASD(all P<0.05). Compared to the mild group, the moderate and severe groups showed significant differences in OSDI, CFS, and ICD(all P<0.05), though no significant differences existed between moderate and severe groups(all P>0.05). At 3 mo after treatment, all groups showed no significant differences in NITMH(all P>0.05). All parameters improved significantly in the mild group(all P<0.05); all indicators improved in the moderate group(P>0.05), except for MGASD before and after treatment(all P<0.05); significant improvements were noted in OSDI, CFS, and NIBUTav in the severe group(all P<0.05), while MGES and MGYSS did not differ significantly(all P>0.05). IVCM parameters(MGAUD, ICD, MGALD, and MGASD)showed no significant change in the severe group(all P>0.05).CONCLUSION:OPT effectively enhances various ocular surface functions and improves gland expressibility and secretion quality in mild to moderate MGD cases, while also positively impacting certain cellular parameters. In severe cases, where most acinar functions are lost and structural reversibility is limited, OPT can still mitigate MGD symptoms and decelerate disease progression.

This study investigated the effect of Wuling San on transforming growth factor-β1(TGF-β1)-induced fibrosis, inflammation, and oxidative stress in human renal tubular epithelial cells(HK-2) and its mechanism of antioxidant stress injury. HK-2 cells were cultured in vitro and divided into a control group, a TGF-β1 model group, and three treatment groups receiving Wuling San-containing serum at low(2.5%), medium(5.0%), and high(10.0%) doses. TGF-β1 was used to establish the model in all groups except the control group. CCK-8 was used to analyze the effect of different concentrations of Wuling San on the activity of HK-2 cells with or without TGF-β1 stimulation. The expression of key fibrosis molecules, including actin alpha 2(Acta2), collagen type Ⅰ alpha 1 chain(Col1α1), collagen type Ⅲ alpha 1 chain(Col3α1), TIMP metallopeptidase inhibitor 1(Timp1), and fibronectin 1(Fn1), was detected using qPCR. The expression levels of inflammatory cytokines, including tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6), interleukin-8(IL-8), and interleukin-4(IL-4), were measured using ELISA kits. Glutathione peroxidase(GSH-Px), malondialdehyde(MDA), catalase(CAT), and superoxide dismutase(SOD) biochemical kits were used to analyze the effect of Wuling San on TGF-β1-induced oxidative stress injury in HK-2 cells, and the expression of nuclear factor E2-related factor 2(Nrf2), heme oxygenase 1(HO-1), and NAD(P)H quinone oxidoreductase 1(NQO1) was analyzed by qPCR and immunofluorescence. The CCK-8 results indicated that the optimal administration concentrations of Wuling San were 2.5%, 5.0%, and 10.0%. Compared with the control group, the TGF-β1 model group showed significantly increased levels of key fibrosis molecules(Acta2, Col1α1, Col3α1, Timp1, and Fn1) and inflammatory cytokines(TNF-α, IL-1β, IL-6, IL-8, and IL-4). In contrast, the Wuling San administration groups were able to dose-dependently inhibit the expression levels of key fibrosis molecules and inflammatory cytokines compared with the TGF-β1 model group. Wuling San significantly increased the activities of GSH-Px, CAT, and SOD enzymes in TGF-β1-stimulated HK-2 cells and significantly inhibited the level of MDA. Furthermore, compared with the control group, the TGF-β1 model group exhibited a significant reduction in the expression of Nrf2, HO-1, and NQO1 genes and proteins. After Wuling San intervention, the expression of Nrf2, HO-1, and NQO1 genes and proteins was significantly increased. Correlation analysis showed that antioxidant stress enzymes(GSH-Px, CAT, and SOD) and Nrf2 signaling were significantly negatively correlated with key fibrosis molecules and inflammatory cytokines in the TGF-β1-stimulated HK-2 cell model. In conclusion, Wuling San can inhibit TGF-β1-induced fibrosis in HK-2 cells by activating the Nrf2 signaling pathway, improving oxidative stress injury, and reducing inflammation.

This paper explored the specific mechanism of ginsenoside Rg_1 in regulating mitochondrial fusion through the neurogenic gene Notch homologous protein 1(Notch1) pathway to alleviate hypoxia/reoxygenation(H/R) injury in HL-1 cells. The relative viability of HL-1 cells after six hours of hypoxia and two hours of reoxygenation was detected by cell counting kit-8(CCK-8). The lactate dehydrogenase(LDH) activity in the cell supernatant was detected by the lactate substrate method. The content of adenosine triphosphate(ATP) was detected by the luciferin method. Fluorescence probes were used to detect intracellular reactive oxygen species(Cyto-ROS) levels and mitochondrial membrane potential(ΔΨ_m). Mito-Tracker and Actin were co-imaged to detect the number of mitochondria in cells. Fluorescence quantitative polymerase chain reaction and Western blot were used to detect the mRNA and protein expression levels of Notch1, mitochondrial fusion protein 2(Mfn2), and mitochondrial fusion protein 1(Mfn1). The results showed that compared with that of the control group, the cell activity of the model group decreased, and the LDH released into the cell culture supernatant increased. The level of Cyto-ROS increased, and the content of ATP decreased. Compared with that of the model group, the cell activity of the ginsenoside Rg_1 group increased, and the LDH released into the cell culture supernatant decreased. The level of Cyto-ROS decreased, and the ATP content increased. Ginsenoside Rg_1 elevated ΔΨ_m and increased mitochondrial quantity in HL-1 cells with H/R injury and had good protection for mitochondria. After H/R injury, the mRNA and protein expression levels of Notch1 and Mfn1 decreased, while the mRNA and protein expression levels of Mfn2 increased. Ginsenoside Rg_1 increased the mRNA and protein levels of Notch1 and Mfn1, and decreased the mRNA and protein levels of Mfn2. Silencing Notch1 inhibited the action of ginsenoside Rg_1, decreased the mRNA and protein levels of Notch1 and Mfn1, and increased the mRNA and protein levels of Mfn2. In summary, ginsenoside Rg_1 regulated mitochondrial fusion through the Notch1 pathway to alleviate H/R injury in HL-1 cells.

Drug administration via hollow microneedles (HMN) have the advantages of painlessness, avoidance of first-pass effect, capability of sustained infusion, and no need for professional personnel operation. In addition, HMN can also be applied in the fields of body fluid extraction and biosensors, showing broad application prospects. However, traditional manufacturing technologies cannot meet the demand for low-cost mass production of HMN, limiting its widespread application. This paper reviews the main manufacturing technologies used for HMN in recent years, which include photolithography and etching, laser etching, sputtering and electroplating, micro-molding, three-dimensional (3D) printing and drawing lithography. It further analyzes the characteristics and limitations of existing manufacturing technologies and points out that the combination of various manufacturing technologies can improve production efficiency to a certain extent. In addition, this paper looks forward to the future trends of HMN manufacturing technology and proposes possible directions for its development. In conclusion, it is expected that this review can provide new ideas and references for follow-up research.
