ObjectiveTo investigate whether co-activated mesenchymal stem cells(MSCs) exert therapeutic effects against schistosomiasis by modulating macrophage polarization. MethodsTwenty adult male Balb/c mice were randomly divided into four groups: uninfected, infected, MSC-treated, and MSCTLR4+IFN-γ-treated groups. The Schistosoma japonicum infection model was established via abdominal patch method with cercariae. At week 5 post-infection, praziquantel was administered orally for antiparasitic treatment. At week 6, mice received either MSCs treatments (with or without pre-activation) or no treatment. Body weight changes were monitored weekly. Hepatic pathological alterations were evaluated via HE and Masson staining. RT-qPCR was used to assess α-SMA and collagen (Col-I, Col-Ⅲ) mRNA levels to quantify fibrosis. The mRNA levels of hepatic inflammatory cytokines and matrix metalloproteinases(MMP) were analyzed to explore fibrotic mechanisms. The expressions of i-Nos and Arg-1 in liver tissues were detected by RT-qPCR, and the ratio of M1 or M2 macrophages was detected by immunofluorescence staining, aiming to analyze the correlation between MSCs treatment and macrophage polarization. An in vitro co-culture system validated direct MSC-macrophage interactions. ResultsCompared with the infected group, the MSCTLR4+IFN-γ group exhibited increased body weight gain (P< 0.01), reduced hepatic granulomatous lesion area (P< 0.001), and decreased α-SMA, Col-I, and Col-Ⅲ mRNA levels (P< 0.01). Additionally, the MSCTLR4+IFN-γ group showed reduced TNF-α and IL-1β expression (P< 0.05), as well as elevated MMP2, Mmp9, and MMP13 levels (P< 0.01). The MSCTLR4+IFN-γ group showed higher expression of M2 marker Arg-1 mRNA compared with the infection group (P < 0.001) , while the expression of M1 marker i-Nos decreased (P< 0.05). Immunofluorescence confirmed a lower i-Nos+ cell ratio (P< 0.05) and higher F4/80+CD206+ cell ratio (P< 0.000 1) in the MSCTLR4+IFN-γ group compared with the infection group. In vitro co-culture experiments further demonstrated that MSCTLR4+IFN-γ promoted Arg-1 expression, suppressed pro-inflammatory cytokine i-Nos and TNF-α levels, consistent with ELISA results. ConclusionsThis study reveals that TLR4 and IFN-γ co-activated MSCs alleviate Schistosoma japonicum-induced hepatic fibrosis, potentially through modulating macrophage polarization toward the M2 phenotype. This mechanism may suppress inflammation and enhance extracellular matrix degradation, providing a therapeutic strategy for schistosomiasis-associated liver fibrosis.

Natural killer cells(NK)are important innate immune cells that do not require prior antigen exposure and can directly recognize and attack virus-infected cells and tumor cells.The activation and effector functions of NK cells are regulated by a balance of signals delivered through their surface activating receptors and inhibitory re-ceptors,which bind to ligands on target cells to achieve cytotoxicity via"induced self"and"missing self"recogni-tion models.The killing mechanisms of NK cells primarily include release of cytotoxic granules such as perforin and granzymes to induce target cell lysis,death receptor-mediated apoptosis,secretion of various cytokines,chemokines and growth factors to coordinate with other immune cells in killing tumor cells,thereby generating secondary im-mune responses and antibody-dependent cellular cytotoxicity(ADCC).

Objective:To establish a method for detecting serum non-ceruloplasmin-bound copper (NCC) by immunoprecipitation-inductively coupled plasma mass spectrometry (IP-ICP-MS) and evaluate its clinical application.Methods:Methodological evaluation research. Immunoprecipitation was first used to separate serum ceruloplasmin, followed by detection of serum NCC levels using ICP-MS. Two levels of quality control serum were reconstituted to determine the limit of detection (LOD), limit of quantitation (LOQ), accuracy, and precision of the self-developed method. The serum samples of 131 healthy individuals (healthy group) and 69 first-time diagnosed Wilson′s disease (WD) patients(WD group) from November 2023 to June 2024 in the Affiliated Hospital of Institute of Neurology, Anhui University of Traditional Chinese Medicine were collected. Using self-developed method detected the serum NCC levels, established the healthy reference intervals, and NCC levels between the two groups were compared using the Mann-Whitney U test. Results:The calibration curve exhibited excellent lineary across the concentration range of 1.562 to 300.000 μg/L, as demonstrated by coefficient of determination ( R2) of 0.999. The self-developed NCC method exhibited that the LOD was 0.99 μg/L, the LOQ was 3.29 μg/L, the accuracy (spike and recovery experience) was 87.67%?106.27%, and the intra-batch and inter-batch imprecision expressed as coefficient of variation ( CV) was 2.8%?7.3%, and the healthy reference range was 34.31-71.79 μg/L. The serum NCC levels in the WD group were 102.39 (74.38, 144.04) μg/L, which was significantly higher than those in healthy group (51.45±10.34) μg/L ( Z=?7.967, P<0.01). Conclusions:The established IP-ICP-MS method for detecting serum NCC meets the required analytical performance criteria. It is simply operative, highly sensitive, and provides accurate and reliable results, which could be used for clinical detection.

ObjectiveTo evaluate the clinical efficacy and safety of Tongluo Mingmu capsules in the treatment of diabetic retinopathy with blood stasis, collateral obstruction, and Qi and Yin deficiency syndrome. MethodA randomized, double-blind, positive-control, and multi-center clinical trial design method was used. 416 patients with diabetic retinopathy with blood stasis, collateral obstruction, and Qi and Yin deficiency syndrome in four test centers were included (the ratio of the treatment group to the control group was 3∶1). On the basis of standardized hypoglycemic treatment, the treatment group was given both four Tongluo Mingmu capsules and two Calcium Dobesilate capsule agents three times a day, while the control group were given both two Calcium Dobesilate capsules and four Tongluo Mingmu capsule agents three times a day. The course of treatment was 12 weeks. The curative effect of Tongluo Mingmu capsules was evaluated by comparing the comprehensive curative effect of diabetic retinopathy, traditional Chinese medicine(TCM) syndrome score, corrected visual acuity, fundus changes, fundus fluorescence angiography, and other curative effect indexes before and after treatment in the two groups. At the same time, general examination, laboratory examination, and adverse events were performed to evaluate the safety of the drug. ResultThe baseline demographic data and disease characteristics of the treatment group and the control group were balanced and comparable, with the difference not statistically significant. After 12 weeks of treatment, the total effective rate of the comprehensive curative effect of diabetic retinopathy in the treatment group (61.0%, 189/310) was better than that in the control group (44.1%, 45/102), and the difference was statistically significant (χ2=8.880, P<0.01). The total effective rate of TCM syndromes in the treatment group (88.4%, 259/293) was better than that in the control group (69.9%, 65/93), and the difference was statistically significant (χ2=17.927, P<0.01). The disappearance rate of dry eyes (χ2=8.305), dull complexion (χ2=4.053), lassitude (χ2=10.267), shortness of breath (χ2=8.494), and dry stool (χ2=8.657) in the treatment group was higher than that in the control group, and the difference between the groups was statistically significant (P<0.05, P<0.01). In terms of improving corrected visual acuity (χ2=8.382), fundus changes (χ2=6.026) , the treatment group was significantly better than the control group (P<0.05). During the trial, the incidence of adverse events in the treatment group and the control group was 1.3% and 2.9%, respectively. There was no significant difference between the two groups. In addition, there were no serious adverse events and adverse events leading to withdrawal in both groups. ConclusionTongluo Mingmu capsules can improve the comprehensive curative effect of diabetic retinopathy and enhance the efficacy of TCM syndromes, visual acuity, fundus changes, and fundus fluorescein angiography, with great safety. Therefore, it can provide a new alternative therapeutic drug for patients with diabetic retinopathy.
