As artificial intelligence technology gains widespread adoption in biomedicine, the exploration of integrating biofluidic Raman spectroscopy for enhanced disease diagnosis opens up new prospects for the practical application of Raman spectroscopy in clinical settings. However, for systemic lupus erythematosus (SLE), origin Raman spectral data (ORS) have relatively weak signals, making it challenging to obtain ideal classification results. Although the surface enhancement technique can enhance the scattering signal of Raman spectroscopic data, the sensitivity of the SERS substrate to airborne impurities and the inhomogeneous distribution of hotspots degrade part of the signal. To fully utilize both kinds of data, this paper proposes a two-branch residual-attention network (DBRAN) fusion technique, which allows the ORS to complement the degraded portion and thus improve the model's classification accuracy. The features are extracted using the residual module, which retains the original features while extracting the deep features. At the same time, the study incorporates the attention module in both the upper and lower branches to handle the weight allocation of the two modal features more efficiently. The experimental results demonstrate that both the low-level fusion method and the intermediate-level fusion method can significantly improve the diagnostic accuracy of SLE disease classification compared with a single modality, in which the intermediate-level fusion of DBRAN achieves 100% classification accuracy, sensitivity, and specificity. The accuracy is improved by 10% and 7% compared with the ORS unimodal and the SERS unimodal modalities, respectively. The experiment, by fusing the multimodal spectral, realized rapid diagnosis of SLE disease by fusing multimodal spectral data, which provides a reference idea in the field of Raman spectroscopy and can be further promoted to clinical practical applications in the future.

Background: Postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is one of the most common complications after ERCP. The optimal drugs for reducing the risk of PEP are still unclear. This study aimed to compare the efficacy of 9 major drugs used worldwide for the prevention of PEP through a network meta-analysis. Methods: We conducted a systematic search of the literature up to October 2018 on PubMed, Embase, Web of Science, the Cochrane Central Library, and ClinicalTrials.gov. Randomized controlled trials (RCTs) comparing allopurinol, diclofenac, gabexate (GAB), glyceryl trinitrate (GTN), indomethacin, nafamostat, octreotide, somatostatin, and ulinastatin for protection against PEP were included. Results: Eighty-six randomized controlled trials involving 25,246 patients were included in this network meta-analysis. Results indicated that diclofenac, GAB, GTN, indomethacin, somatostatin, and ulinastatin were more effective than placebo with odds ratios ranging between 0.48 (95% credible interval, 0.26-0.86) for GAB and 0.61 (0.39-0.94) for somatostatin. However, allopurinol, nafamostat, and octreotide showed similar efficacy as placebo in reducing the risk of PEP. No significant differences were found in the efficacy between diclofenac, GAB, GTN, indomethacin, somatostatin, and ulinastatin. In terms of prognosis, GAB may be the most effective treatment (surface under the cumulative ranking curve=70.6%) and the least effective was octreotide (surface under the cumulative ranking curve=28%). Conclusions: Although our analysis suggests that GAB may be the most effective drug in preventing PEP, the limitations of our study warrants more high-quality head-to-head trials of these clinical drugs in the future.

Background Cutaneous involvement is a common manifestation of systemic lupus erythematosus (SLE), and dyslipidemia has emerged as a metabolic factor that aggravates lupus-associated skin injury. Purpose This study investigated the effects of Xijiao Dihuang Decoction derived formula (XJDHD) on dyslipidemia-aggravated lupus skin injury and its underlying immunometabolic mechanisms. Methods A high-fat diet (HFD)-exacerbated lupus-like skin injury model was established in lupus-prone mice. Histopathological, lipid metabolic, inflammatory, and oxidative stress analyses were conducted. Mechanistic exploration integrated molecular docking, network pharmacology, RNA sequencing, and macrophage-based assays. Results XJDHD markedly alleviated HFD-aggravated lupus-like skin lesions, reduced lipid accumulation, and suppressed cutaneous inflammation. Integrated analyses identified PPARγ-associated fatty acid oxidation and mitochondrial regulation as central pathways. XJDHD enhanced fatty acid oxidation, restored mitochondrial homeostasis, reduced oxidative stress, and inhibited pro-inflammatory macrophage polarization. PPARγ, ACADM, and NDUFAB1 were identified as key targets. Conclusion XJDHD attenuates dyslipidemia-associated lupus skin injury by restoring immunometabolic balance through regulation of fatty acid oxidation and mitochondrial homeostasis via the PPARγ-ACADM-NDUFAB1 axis, supporting metabolic-targeted herbal therapy for cutaneous manifestations in SLE.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease . This study aimed to investigate the role of SMAD specific E3 ubiquitin protein ligase 1 (SMURF1) in the Th17 and Th17.1 differentiation and Treg/Th17 imbalance, which are major factors contributing to the pathogenesis of SLE. SLE patients and healthy individuals were recruited to detect the SMURF1 levels in naïve CD4 + cells from peripheral blood. Purified and expanded naïve CD4 + T cells were employed to evaluate the effects of SMURF1 on Th17 and Th17.1 polarization in vitro. MRL/lpr lupus model was employed to explore the disease phenotype as well as Treg/Th17 balance in vivo. The results showed that SMURF1 was down-regulated in naïve CD4 + T cells in peripheral blood of patients with SLE and in spleen of MRL/lpr mice. SMURF1 overexpression suppressed the polarization of naïve CD4 + T cells toward Th17 and Th17.1 phenotype and down-regulated the expression of retinoid-related orphan receptor-gammat (RORγt). Subsequently, SMURF1 down-regulation aggravated the disease phenotype, inflammation, and the Treg/Th17 imbalance in MRL/lpr mice. Furthermore, we found that SMURF overexpression promoted the ubiquitination and decreases the stability of RORγt. In conclusion, SMURF1 inhibited the polarization of Th17 and Th17.1 cells and improved the Treg/Th17 imbalance in SLE, which was mediated as least partly by the ubiquitination of RORγt.

To understand the interrelationships within the multi-ion coexisting sulfate system during the solid–liquid transformation of polyhalite in the Bieletan area, phase equilibria of ternary systems M, Ca2+//SO42–-H2O (M = Na+, K+, Mg2+) at 288.2 K were studied by the isothermal dissolution equilibrium method. The solubility and density of the equilibrium liquid phases of the system were measured experimentally, and the composition of the equilibrium solid phase at the ternary invariant point was determined by X-ray powder diffractometry. It is found that the ternary system K+, Ca2+//SO42–-H2O at 288.2 K forms the double salt syngenite (K2SO4·CaSO4·H2O), while the systems Na+, Ca2+//SO42–-H2O and Mg2+, Ca2+//SO42–-H2O at 288.2 K only form with the formation of CaSO4·2H2O and Na2SO4·10H2O (MgSO4·7H2O). Multitemperature comparison of the M, Ca2+//SO42–-H2O (M = Na+, K+, Mg2+) systems shows that the phase diagrams of Mg2+, Ca2+//SO42–-H2O are consistent at the selected temperature, only containing CaSO4·2H2O and MgSO4·nH2O (n = 1, 6, 7). While K+, Ca2+//SO42–-H2O and Na+, Ca2+//SO42–-H2O change from 288.2 and 298.2 to 348.2 K, the phase diagram forms double salt(s) K2SO4·5CaSO4·H2O (Na2SO4·5CaSO4·3H2O and Na2SO4·CaSO4).

Mesenchymal stem cells (MSCs) transplantation is an emerging and attractive therapy for immune dysregulation diseases like systemic lupus erythematosus (SLE). However, its application is hindered by short in vivo persistence and poor cellular survival after injection. Here, inspired by the native extracellular matrix (ECM) composition , we presented a novel peptide dendrimer-based microgel encapsulated with MSCs via a microfluidic approach for SLE treatment. By varying microfluidic parameters, monodisperse microgels with tunable diameters, porous microstructures, mechanical stiffness, and immune-isolation potential could be precisely achieved. As the water polymerization environment and ECM like components, the resultant microgels exhibited minimal toxicity in vivo and in vitro. We have also demonstrated that the MSCs encapsulated microgels could significantly increase the cellular bioactivity , enhance the immunomodulatory function, and attenuate disease symptoms in MRL/lpr mice. These results indicate the bioinspired microgels with MSCs encapsulation have potential clinical values in the treatment of SLE and other immune dysregulation diseases.

Although eutectic solvents (ESs) have received considerable attention as sustainable process fluids for various applications, discovering novel ESs remains challenging as computational methods for predicting the formation of eutectics are still scarce. In the present work, both the original and modified UNIFAC models are evaluated and extended for predicting the solid–liquid equilibria (SLE) of ES systems. The applicability of the two versions of UNIFAC models is first evaluated based on the SLE of 25 ES systems composed of only conventional components. Motivated by the good evaluation results, the SLE of 50 ES systems involving one salt component are employed to extend the UNIFAC models to include novel salt-component-related functional groups. The obtained models cover widely-reported salt components of choline/tetraalkylammonium chloride/bromide and conventional components of fatty alcohols and fatty/dicarboxylic/α-hydroxy acids. A theoretical design of novel ESs in a large scale is performed with the best-performing model extension, wherein four designed ES systems are validated experimentally.

An autoimmune condition known as systemic lupus erythematosus (SLE) is characterized by B cell hyperresponsiveness and persistent generation of pathogenic autoantibodies that cause damage to various organs and tissues. The treatments available today are either ineffective or have adverse effects. The dysregulation of B cell activation is crucial for the emergence of SLE. MiR-7 explicitly targeted PTEN mRNA in B cells. Treatment with antagomiR-7 reduced B cell hyperresponsiveness and prevented the onset of lupus. As a result, inhibiting miR-7 may be used therapeutically to treat SLE. We developed a SA (sialic acid)-poly (D, L-lactide-co-glycolide) (SA-PLGA) nano delivery system to deliver antagomiR-7 into splenic B cells since the stability and targeted delivery of miRNA remain significant challenges in vivo . Results show that SA-PLGA nanoparticles (SA-PLGA@antagomiR-7) loaded with antagomiR-7 display good biocompatibility and shield antagomiR-7 from degradation, extending the miRNA’s duration in circulation in vivo . Additionally, in MRL/Ipr lupus mice, SA-PLGA@antagomiR-7 is successfully delivered to the splenic B cells and preferentially enriched in the diseased spleen in MRL/Ipr lupus mice. The SA-PLGA@antagomiR-7 NPs therapy effectively decreases immunological abnormalities, normalizes splenic B cell subtypes, and suppresses B cell activation. The antagomiR-7 NPs exhibit excellent therapeutic efficiency and high biosafety collectively, which may result in a more effective treatment for SLE.

Immune intervention of B cell activation to blockade the production of autoantibodies provokes intense interest in the field of systemic lupus erythematosus (SLE) therapy development. Although the survival rate for SLE is improved, many patients die untimely. Engineered cell membrane vesicles manifest remarkable capacity of targeted drug delivery and immunomodulation of immune cells such as B cells. Herein, this work engineered cellular nanovesicles (NVs) presenting CD40 (CD40 NVs) that can blunt B cells and thus alleviate SLE. CD40 NVs disrupt the CD40/CD40 ligand (CD40L) costimulatory signal axis through the blockade of CD40L on CD4 + T cells. Therefore, the CD40 NVs restrain the generation of the germinal center structure and production of antibodies from B cells. Furthermore, immunosuppressive drug mycophenolate mofetil (MMF) is also encapsulated in the vesicles (MMF-CD40 NVs), which is employed to deplete immunocytes including B cells, T cells, and dendritic cells. Together, CD40 NVs are promising formulations for relieving autoimmunity and lupus nephritis in MRL/lpr mice.

Pearl powder has been used in medicine and beauty treatment since ancient times in China. However, it is still unclear whether the biological activities of pearl powder are affected by different extraction methods or not. In this study, we determine the total protein yield, protein molecular weight and biological activities including antioxidant, tyrosinase inhibition and melanogenesis inhibition activities and cytotoxicity of different pearl powder extracts prepared by five different preparation methods. The ultrasonic-assisted extraction (UAE) and microwave-assisted extraction (MAE) of pearl powder were optimized by the response surface method based on total protein yield. Compared with solid-liquid extraction (SLE), the optimized UAE and MAE increased the total protein yield without changing protein molecular weight. In addition, the extract by MAE enhanced the tyrosinase inhibition activity and anti-melanogenesis activity slightly. Acidolysis hydrolyzes macromolecular protein into small molecules with obvious cytotoxicity and low activities. Enzymolysis can hydrolyze macromolecular protein into small molecules with high protein yield and improvement of bioactivities. In the determination of the antioxidant assay, the extract prepared by the enzymolysis showed significant activity. These results suggest that protein molecules of the pearl powder extract are degraded appropriately by enzymolysis to smaller molecules to obtain the enhanced biological activities that can be applied in the cosmetic industry.
