Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

The gut microbiota is a vast microbial ecosystem,specifically present in the organism and plays an important regulatory role in the body's health or disease state together with its metabolites.After spinal cord injury,the complex pathophysiology at the site of trauma makes axonal regeneration difficult,and the autonomic motor dysfunction induced by spinal cord injury disrupts gastrointestinal function and causes gut microbiota imbalance.The previous clinical outcomes of neurorepair strategies after spinal cord injury have not been ideal.The dysregulated gut microbiota and neuroinflammation after spinal cord injury are closely associated with the prognosis of the patients.The potential mechanisms by which the gut microbiota may influence the neuroinflammation after spinal cord injury may include the activation of gut-associated lymphoid tissue and disruption of the intestinal barrier by the imbalanced microbiota,and gut microbiota and its metabolites such as lipopolysaccharides(LPS),short chain fatty acids(SCFAs),5-hydroxytryptamine(5-HT),and tryptophan,as well as immune cells,inflammatory factors,and neurotransmitters the local inflammatory response in the spinal cord through the circulatory system.This paper revews the studies on the changes in gut microbiota after spinal cord injury and their effects on the spinal cord neuroinflammation,providing new targets and new ideas for improving the neuroinflammation after spinal cord injury.

Objective:To evaluate the 3-year survival outcomes and late injury between the self-designed patent single-channel applicator, which was modified from the traditional tandem applicator and wrapped with a oval-shield alloy around the source channel and standard Fletcher-type applicator in the high-dose-rate brachytherapy for cervical cancer.Methods:Patients initially diagnosed with cervical cancer in the Affiliated Hospital of Southwest Medical University from December 2011 to April 2017 were enrolled and randomly assigned into the external beam radiotherapy (EBRT)+ single-channel intracavitary applicator group (the patent single-channel group) and EBRT+ the Fletcher applicator group. The whole pelvis irradiation was delivered with 6-MV photons via a four-field box variant or anterior and posterior parallel fields. Five to six fractions of intracavitary brachytherapy were performed at a dose of 7 Gy at point A once a week after 30 Gy (Equivalent Dose in 2 Gy at point A: 80-90 Gy). Chemotherapy was given with intravenous injection of cisplatin at a dose of 40 mg/m 2 once weekly during EBRT. Clinical efficacy and safety were evaluated after corresponding treatment. Results:In total, 150 eligible cases were assigned into the Fletcher applicator group and 149 cases into the patent single-channel group. Up to December 2020, all patients had been followed up for 3 years, and the median duration of follow-up was 61 months. In the Fletcher group, the 3-year overall survival, progression-free survival and locoregional failure-free survival was 76.3%, 78.1% and 75.4%, and 83.8%, 80.3% and 85.5% in the single-channel group, respectively. In the Fletcher group, the cumulative rate of grade 3-4 late rectal complications was 3.3% and 6.7% in the single-channel group ( P=0.122). The cumulative rate of grade 3-4 bladder complications was 1.3% in the Fletcher group and 0.7% in the single-channel group ( P=1.000). Conclusion:The self-designed patent single-channel intracavitary applicator yields equivalent long-term clinical efficacy and safety to the standard Fletcher-type three-channel applicator in the HDR brachytherapy for uterine cervical cancer.

OBJECTIVE:To compare pharmacoeconomic and effect of Xueshuantong for injection and Ginkgo leaf extract and dipyridamole injection in the treatment of ischemic stroke. METHODS:Retrospective study was conducted. Totally 404 inpatients with ischemic stroke were divided into Xueshuantong group(271 cases)and ginkgo leaf extract and dipyridamole group(133 cas-es) according to clinical treatment programs. Based on the conventional treatment,patients in 2 groups were given Xueshuantong for injection and ginkgo leaf extract and dipyridamole injection,respectively. The average treatment course was 10 d. Cost-minimi-zation analysis was performed with the determination index of total effective rate. RESULTS:The total effective rates in Xueshuan-tong group and ginkgo leaf extract and dipyridamole group were 90.77% and 88.72%,respectively,the difference was not statisti-cally significant(P>0.05). The costs in 2 groups were 12 860.21 yuan and 13 155.40 yuan,respectively,and xueshuantong group had lower than ginkgo leaf extract and dipyridamde group. CONCLUSIONS:Both Xueshuantong for injection and Ginkgo leaf ex-tract and dipyridamole injection are effective in the treatment of ischemic stroke. However,the economy of Xueshuantong for injec-tion is superior to the other one.

This study was aimed to observe the influence of water-solubility nipponica saponin on activation of TNF-α+IL-17-induced rat fibroblast-like synovial cell line RSC-364 cellular model nuclear transcription factor NF-κB pathway as well as TNF-α, IL-1, ICAM-1, MMP-2, MMP-3 secretion. IL-17+ TNF-α were used for stimulating RSC-364 to establish rheumatoid arthritis (RA) cellular model. Water-solubility nipponica saponin in different con-centrations was used for intervention. The influence of water-solubility nipponica saponin in different concentrations on cell viability was detected by semi-quantitative RT-PCR method. Changes in the level of TNF-α, IL-1, ICAM-1, MMP-2, and MMP-3 of culture supernatant were detected by ELISA. The results showed that the activation of NF-κB p65 in RSC-364 stimulated by TNF-α+ IL-17 can be inhibited by water-solubility nipponica saponin ac-cording to its concentration. It improved IκB-α expression, and inhibited TNF-α, IL-1, ICAM-1, MMP-2 and MMP-3 secretion. It was concluded that water-solubility nipponica saponin can inhibit the activation of NF-κB pathway, hinder the secretion and activation of multiple downstream genes, which may be its effect in inhibiting syn-ovial inflammation in RA.
