Rheumatoid arthritis(RA) is a widely prevalent autoimmune inflammatory disease that severely affects patients' quality of life. Currently, conventional formulations against RA have several limitations, such as nonspecificity, poor efficacy, large drug dosages, frequent administration, and systemic side effects. Nanotechnology-based drug delivery systems have emerged as a promising stra-tegy for the diagnosis and treatment of RA since nanotechnology can overcome the limitations of traditional treatments and simplify the complexity of the disease. These systems enable targeted delivery of anti-inflammatory drugs to the inflamed areas through active and passive targeting, achieving specificity to the joints, overcoming the need for increased dosage and administration frequency, and reducing associated adverse reactions. This article aimed to review nanocarrier-based drug delivery systems in the field of RA and elucidate how nanosystems can be utilized to deliver therapeutic drugs to inflamed joints for controlling RA progression. By discussing the current issues and challenges faced by nanodrug delivery systems and highlighting the urgent need for solutions, this article offers theoretical support for further research on nanotechnology-based co-delivery systems in the future.

OBJECTIVETo investigate the quantities of bone marrow CD5+ B lymphocytes in the patients with autoimmune hemocytopenia and the relationship between quantities of CD5+ B lymphocytes and clinical or laboratorial parameters.

METHODSQuantities of CD5+ B lymphocytes in the bone marrow of 14 patients with autoimmune hemolytic anemia (AIHA) or Evans syndrome, 22 immunorelated pancytopenia (IRP) patients, and 10 normal controls were assayed by flow cytometry. The correlation between their clinical or laboratorial parameters and CD5+ B lymphocytes was analyzed.

RESULTSThe quantity of CD5+ B lymphocytes of AIHA/Evans syndrome (34.64% +/- 19.81%) or IRP patients (35.81% +/- 16.83%) was significantly higher than that of normal controls (12.00% +/- 1.97%, P < 0.05). However, there was no significant difference between AIHA/Evans syndrome and IRP patients (P > 0.05). In all hemocytopenic patients, the quantity of bone marrow CD5+ B lymphocytes showed significantly negative correlation with serum complement C3 level (r = -0.416, P < 0.05). In the patients with AIHA/Evans syndrome, the quantity of bone marrow CD5+ B lymphocytes showed significantly positive correlation with serum indirect bilirubin level (r = 1.00, P < 0.05). In Evans syndrome patients, the quantity of CD5+ B lymphocytes in bone marrow showed significantly positive correlation with platelet-associated immunoglobulin G (r = 0.761, P < 0.05) and platelet-associated immunoglobulin M ( r = 0.925, P < 0.05). The quantity of CD5+ B lymphocytes in bone marrow of all hemocytopenic patients showed significantly negative correlation with treatment response (tau-b = -0.289, P < 0.05) , but had no correlation with colony forming unit-erythroid (r = -0.205, P > 0.05) or colony forming unit-granulocyte-macrophage colonies (r = -0.214, P > 0.05).

CONCLUSIONSThe quantity of bone marrow CD5+ B lymphocytes in the patients with autoimmune hemocytopenia significantly increases and is correlated with disease severity and clinical response, which suggest that CD5+ B lymphocytes might play an important role in the pathogenesis of autoimmune hemocytopenia.

Traditional medications used for treating autoimmune diseases often come with a wide range of adverse effects. Current treatments focus mainly on symptom management, resulting in significant health issues and financial burdens for patients. Recently, clinical research has demonstrated the potential of helminths and their derivatives as effective therapies for autoimmune disorders. Helminths, being a near-natural immunomodulator, exhibit milder effects than broad-spectrum immunosuppressants and corticosteroids, thereby presenting a promising alternative for the treatment of autoimmune diseases. However, different helminths' therapeutic efficacy and mechanisms and their derivatives in treating autoimmune diseases may vary. Therefore, we aim to review recent clinical advancements in the use of helminths and their derivatives for treating inflammatory bowel disease, multiple sclerosis, and autism spectrum disorder, with a view to offering novel clinical treatment approaches.

IgG4-related disease (IgG4-RD) is a rare autoimmune fibrosis disease characterized by elevated serum IgG4 and tissues as well as organs infiltrated with IgG4-positive cells, resulting in swelling and damage.It is currently treated as first-line treatment with glucocorticoids. Autoimmune hemolytic anemia (AIHA) is also a relatively rare disease that caused by autoreactive erythrocyte antibodies. Although both are autoimmune-related diseases, they rarely overlap. The relationship between them is not clear. A case of IgG4-RD combined with AIHA is reported. The patient has shortness of breath, cough, and sputum after physical activity. Physical examination showed appearance of anemia, yellow staining of skin and sclera, palpable neck and multiple swollen lymph nodes. Laboratory examination, bone marrow biopsy, and lymph node biopsy confirmed the diagnosis. Therefore, clinicians should develop ideas and raise awareness of such diseases.

Kaposi sarcoma (KS) has attracted much attention recently because of its high incidence among patients with acquired immune deficiency syndrome. Other groups with a high risk of developing KS are renal transplant recipients treated with immunosuppressive drugs and, to a lesser extent, patients with autoimmune diseases. We report the case of a patient who developed KS during corticosteroid therapy for idiopathic thrombocytopenic purpura, which subsequently regressed with combination chemotherapy.

FcγRIIB, the only inhibitory IgG Fc receptor, functions to suppress the hyper-activation of immune cells. Numerous studies have illustrated its inhibitory function through the ITIM motif in the cytoplasmic tail of FcγRIIB. However, later studies revealed that in addition to the ITIM, the transmembrane (TM) domain of FcγRIIB is also indispensable for its inhibitory function. Indeed, recent epidemiological studies revealed that a non-synonymous single nucleotide polymorphism (rs1050501) within the TM domain of FcγRIIB, responsible for the I232T substitution, is associated with the susceptibility to systemic lupus erythematosus (SLE). In this review, we will summarize these epidemiological and functional studies of FcγRIIB-I232T in the past few years, and will further discuss the mechanisms accounting for the functional loss of FcγRIIB-I232T. Our review will help the reader gain a deeper understanding of the importance of the TM domain in mediating the inhibitory function of FcγRIIB and may provide insights to a new therapeutic target for the associated diseases.

Rhei Radix et Rhizoma was first recorded in Shennong Ben Cao Jing, with a wide range of pharmacological activities. Autoimmune disease is a kind of disease that damages the tissue structure and function of immune cells and their components due to the impairment of immune tolerance function, including atherosclerosis, multiple sclerosis, gout, rheumatoid arthritis, autoimmune thyroiditis, ulcerative colitis, type 1 diabetes and IgA nephropathy. In recent years, clinical and experimental studies show that Rhei Radix et Rhizoma has potential therapeutic effects on autoimmune diseases. Under the guidance of the theory of traditional Chinese medicine, this paper reviews therapeutic and intervening effects of Rhei Radix et Rhizoma and its main active ingredient anthraquinone on autoimmune diseases. It also puts forward new study directions in view of the existing problems in studies of rhubarb and its anthraquinone, with the aim to provide reference for clinical treatment and scientific studies of effect of Rhei Radix et Rhizomaon autoimmune diseases.

Sj9gren's syndrome(SS) is an autoimmune disease with glandular dysfunction caused by the massive infiltration of the exocrine glands by lymphocytes. The pathogenesis of this disease is related to the chronic inflammatory response of the exocrine glands due to excessive activation of B cells and T cells. In addition to dry mouth and eyes, SS can also cause damage to other organs and systems in the human body, seriously affecting the quality of life of patients. Traditional Chinese medicine(TCM) has definite clinical efficacy in the treatment of SS as it can alleviate symptoms and regulate immune disorders without causing adverse reactions, demonstrating high safety. This paper reviews the current status of preclinical and clinical trials about the TCM treatment of SS in the past decade. TCM mainly mitigates SS symptoms such as dry mouth, dry eyes, dry skin, and joint pain and improves the prognosis and quality of life of patients by regulating the abnormally activated B cells and T cells, inhibiting the autoimmune response, restoring the balance between pro-inflammatory and anti-inflammatory cytokines, and reducing the pathological damage caused by immune complexes to exocrine glands and joints in SS patients.
