Metal ion-promoted chemodynamic therapy(CDT) combined with photodynamic therapy(PDT) offers broad application prospects for enhancing anti-tumor effects. In this study, glycyrrhizic acid(GA), copper ions(Cu~(2+)), and norcantharidin(NCTD) were co-assembled to successfully prepare a natural small-molecule, carrier-free hydrogel(NCTD Gel) with excellent material properties. Under 808 nm laser irradiation, NCTD Gel responded to the tumor microenvironment(TME) and acted as an efficient Fenton reagent and photosensitizer, catalyzing the conversion of endogenous hydrogen peroxide(H_2O_2) within the tumor into oxygen(O_2), and hydroxyl radicals(·OH, type Ⅰ reactive oxygen species) and singlet oxygen(~1O_2, type Ⅱ reactive oxygen species), while depleting glutathione(GSH) to stabilize reactive oxygen species and alleviate tumor hypoxia. In vitro and in vivo experiments demonstrated that NCTD Gel exhibited significant CDT/PDT synergistic therapeutic effects. Further safety evaluation and metabolic testing confirmed its good biocompatibility and safety. This novel hydrogel is not only simple to prepare, safe, and cost-effective but also holds great potential for clinical transformation, providing insights and references for the research and development of metal ion-mediated hydrogel-based anti-tumor therapies.

Background:
Intrahepatic cholangiocarcinoma (ICC) is a highly desmoplastic tumor with poor prognosis even after curative resection. We investigated the associations between the composition of the ICC stroma and immune cell infiltration and aimed to develop a stromal-immune signature to predict prognosis in surgically treated ICC.
Patients and methods:
We recruited 359 ICC patients and performed immunohistochemistry to detect α-smooth muscle actin (α-SMA), CD3, CD4, CD8, Foxp3, CD68, and CD66b. Aniline was used to stain collagen deposition. Survival analyses were performed to detect prognostic values of these markers. Recursive partitioning for a discrete-time survival tree was applied to define a stromal-immune signature with distinct prognostic value. We delineated an integrated stromal-immune signature based on immune cell subpopulations and stromal composition to distinguish subgroups with different recurrence-free survival (RFS) and overall survival (OS) time.
Results:
We defined four major patterns of ICC stroma composition according to the distributions of α-SMA and collagen: dormant (α-SMAlow/collagenhigh), fibrogenic (α-SMAhigh/collagenhigh), inert (α-SMAlow/collagenlow), and fibrolytic (α-SMAhigh/collagenlow). The stroma types were characterized by distinct patterns of infiltration by immune cells. We divided patients into six classes. Class I, characterized by high CD8 expression and dormant stroma, displayed the longest RFS and OS, whereas Class VI, characterized by low CD8 expression and high CD66b expression, displayed the shortest RFS and OS. The integrated stromal-immune signature was consolidated in a validation cohort.
Conclusion
We developed and validated a stromal-immune signature to predict prognosis in surgically treated ICC. These findings provide new insights into the stromal-immune response to ICC.

AIM: To explore the progress of clinical trials for ophthalmic drugs in China in 2022 and discuss its changes with 2014 to 2021, thus providing the latest data reference for the development of new drug and the implementation of clinical trials, and a basis for decision-making.METHODS: In this cross-sectional study, we retrieved the drug clinical trials registration and information disclosure platform of National Medical Products Administration database. Drug clinical trials for eye diseases registered from January 1 to December 31, 2022 were included. Number(proportion)was used to describe the characteristics of clinical trials for ophthalmic drug, the indication, the trial phase, the efficacy and the geographical distribution.RESULTS:A total of 55 clinical trials for ophthalmic drug were included, which accounted for 1.66% of all clinical trials, showing a steady growth trend. Main drug type was chemical drugs with the highest proportion of 58.18%. The top three indications with the most clinical trials were age-related macular degeneration, myopia and dry eye. Two gene drugs emerged in 2022, and 7 drugs carried out ≥2 trials, of which atropine sulfate and recombinant anti-vascular endothelial growth factor(VEGF)humanized monoclonal antibody were the most(7 and 5 respectively). Most trials were in phase I and phase III stages, accounting for 36.36% and 27.27% respectively. The median start-up time of phase I trials in 2022 was 2.72(0.77, 3.47)mo, which was significantly shorter than 3.87(3.00, 6.30)mo of 2014~2021(Z=-2.630, P=0.009), and there were no significant differences between BE, phase II, III, IV comparing with 2014~2021(P>0.05).CONCLUSIONS: In 2022, the number and implementation efficiency of clinical trials for ophthalmic drugs in China increased steadily. The indications are mainly fundus disease, myopia and dry eye. Most new drugs are in the early stage of research and development or close to market. Gene therapy drugs began to emerge.

OBJECTIVE:
Physical exercise, a common non-drug intervention, is an important strategy in cancer treatment, including hepatocellular carcinoma (HCC). However, the mechanism remains largely unknown. Due to the importance of hypoxia and cancer stemness in the development of HCC, the present study investigated whether the anti-HCC effect of physical exercise is related to its suppression on hypoxia and cancer stemness.
METHODS:
A physical exercise intervention of swimming (30 min/d, 5 d/week, for 4 weeks) was administered to BALB/c nude mice bearing subcutaneous human HCC tumor. The anti-HCC effect of swimming was assessed in vivo by tumor weight monitoring, hematoxylin and eosin (HE) staining, and immunohistochemistry (IHC) detection of proliferating cell nuclear antigen (PCNA) and Ki67. The expression of stemness transcription factors, including Nanog homeobox (NANOG), octamer-binding transcription factor 4 (OCT-4), v-Myc avian myelocytomatosis viral oncogene homolog (C-MYC) and hypoxia-inducible factor-1α (HIF-1α), was detected using real-time reverse transcription polymerase chain reaction. A hypoxia probe was used to explore the intratumoral hypoxia status. Western blot was used to detect the expression of HIF-1α and proteins related to protein kinase B (Akt)/glycogen synthase kinase-3β (GSK-3β)/β-catenin signaling pathway. The IHC analysis of platelet endothelial cell adhesion molecule-1 (CD31), and the immunofluorescence co-location of CD31 and desmin were used to analyze tumor blood perfusion. SMMC-7721 cells were treated with nude mice serum. The inhibition effect on cancer stemness in vitro was detected using suspension sphere experiments and the expression of stemness transcription factors. The hypoxia status was inferred by measuring the protein and mRNA levels of HIF-1α. Further, the expression of proteins related to Akt/GSK-3β/β-catenin signaling pathway was detected.
RESULTS:
Swimming significantly reduced the body weight and tumor weight in nude mice bearing HCC tumor. HE staining and IHC results showed a lower necrotic area ratio as well as fewer PCNA or Ki67 positive cells in mice receiving the swimming intervention. Swimming potently alleviated the intratumoral hypoxia, attenuated the cancer stemness, and inhibited the Akt/GSK-3β/β-catenin signaling pathway. Additionally, the desmin+/CD31+ ratio, rather than the number of CD31+ vessels, was significantly increased in swimming-treated mice. In vitro experiments showed that treating cells with the serum from the swimming intervention mice significantly reduced the formation of SMMC-7721 cell suspension sphere, as well as the mRNA expression level of stemness transcription factors. Consistent with the in vivo results, HIF-1α and Akt/GSK-3β/β-catenin signaling pathway were also inhibited in cells treated with serum from swimming group.
CONCLUSION
Swimming alleviated hypoxia and attenuated cancer stemness in HCC, through suppression of the Akt/GSK-3β/β-catenin signaling pathway. The alleviation of intratumoral hypoxia was related to the increase in blood perfusion in the tumor. Please cite this article as: Xiao CL, Zhong ZP, Lü C, Guo BJ, Chen JJ, Zhao T, Yin ZF, Li B.

OBJECTIVE:
Jiedu Recipe (JR), a Chinese herbal remedy, has been shown to prolong overall survival time and decrease recurrence and metastasis rates in patients with hepatocellular carcinoma (HCC). This work investigated the mechanism of JR in HCC treatment.
METHODS:
The chemical constituents of JR were detected using liquid chromatography-mass spectrometry. The potential anti-HCC mechanism of JR was screened using network pharmacology and messenger ribonucleic acid (mRNA) microarray chip assay, followed by experimental validation in human HCC cells (SMMC-7721 and Huh7) in vitro and a nude mouse subcutaneous transplantation model of HCC in vivo. HCC cell characteristics of proliferation, migration and invasion under hypoxic setting were investigated using thiazolyl blue tetrazolium bromide, wound healing and Transwell assays, respectively. Image-iT™ Hypoxia Reagent was added to reveal hypoxic conditions. Stem cell sphere formation assay was used to detect the stemness. Epithelial-mesenchymal transition (EMT) markers like E-cadherin, vimentin and α-smooth muscle actin, and pluripotent transcription factors including nanog homeobox, octamer-binding transcription factor 4, and sex-determining region Y box protein 2 were analyzed using Western blotting and real-time polymerase chain reaction. Western blot was performed to ascertain the anti-HCC effect of JR under hypoxia involving the Wnt/β-catenin pathway.
RESULTS:
According to network pharmacology and mRNA microarray chip analysis, JR may potentially act on hypoxia and inhibit the Wnt/β-catenin pathway. In vitro and in vivo experiments showed that JR significantly decreased hypoxia, and suppressed HCC cell features of proliferation, migration and invasion; furthermore, the hypoxia-induced increases in EMT and stemness marker expression in HCC cells were inhibited by JR. Results based on the co-administration of JR and an agonist (LiCl) or inhibitor (IWR-1-endo) verified that JR suppressed HCC cancer stem-like properties under hypoxia by blocking the Wnt/β-catenin pathway.
CONCLUSION
JR exerts potent anti-HCC effects by inhibiting cancer stemness via abating the Wnt/β-catenin pathway under hypoxic conditions.

Objective: To characterize the incidence density of systematic lupus erythematosus (SLE) in Yinzhou District of Ningbo from 2016 to 2021, and compare the age and gender specific differences. Methods: A retrospective cohort study was conducted based on the related data from 2015 to 2021 collected from the Health Information Platform of Yinzhou. Suspected SLE cases in local residents were identified by fuzzy matching of International Classification of Diseases 10th edition code "M32" or Chinese text "lupus". The classification criteria from Systemic Lupus International Collaboration Clinics-2012 and The European League Against Rheumatism/American College of Rheumatology-2019 were used for case verification. SLE cases were identified with specific algorithm based on verification results, and new cases were identified with 1 year as the washout period. The incidence density and 95%CI were estimated by Poisson distribution. Results: From 2016 to 2021, a total of 1 551 921 permanent residents were registered in Yinzhou, in whom 51.52% were women. The M(Q1,Q3) age at enrollment was 40.38 (27.54, 53.54) years. The M(Q1,Q3) of follow-up person-years was 3.83 (0.41, 5.83) years. There were 451 new SLE cases, in which 352 were women (78.05%). The 6-year incidence density was 8.14/100 000 person-years (95%CI: 7.41/100 000 person-years-8.93/100 000 person-years) for the total population, 3.68/100 000 person-years (95%CI: 2.99/100 000 person-years-4.48/100 000 person-years) for men and 12.37/100 000 person-years (95%CI: 11.11/100 000 person-years- 13.73/100 000 person-years) for women. The incidence density in men appeared a small peak at 20-29 years old, and began to increase with age from 40 years old. The incidence density in women was highest in age group 20-29 years (16.57/100 000 person-years) and remained to be high until 30-79 years old. The incidence density of SLE in Yinzhou show no significant temporal trend from 2016 to 2021 (men: P=0.848; women: P=1.000). Conclusions: The incidence density of SLE in Yinzhou from 2016 to 2021 was similar to those of other areas in China. SLE has a high incidence in women, especially in the young and elderly, suggesting that more attention should be paid to the diagnosis and treatment of SLE in women.
