Chimeric antigen receptor (CAR)-T cell therapy has achieved remarkable success in the treatment of hematological malignancies. Based on the immunomodulatory capability of CAR-T cells, efforts have turned toward exploring their potential in treating autoimmune diseases. Bibliometric analysis of 210 records from 128 academic journals published by 372 institutions in 40 countries/regions indicates a growing number of publications on CAR-T therapy for autoimmune diseases, covering a range of subtypes such as systemic lupus erythematosus, multiple sclerosis, among others. CAR-T therapy holds promise in mitigating several shortcomings, including the indiscriminate suppression of the immune system by traditional immunosuppressants, and non-sustaining therapeutic levels of monoclonal antibodies due to inherent pharmacokinetic constraints. By persisting and proliferating in vivo, CAR-T cells can offer a tailored and precise therapeutics. This paper reviewed preclinical experiments and clinical trials involving CAR-T and CAR-related therapies in various autoimmune diseases, incorporating innovations well-studied in the field of hematological tumors, aiming to explore a safe and effective therapeutic option for relapsed/refractory autoimmune diseases.

Alzheimer's disease(AD) is a common neurodegenerative disease with increasing incidence rate. Up to now,there is no ideal treatment for AD. It has become a public health problem worldwide. Traditional Chinese medicine (TCM) believes that kidney deficiency is the key symptomatic element of deterioration and temporal progression symptoms,accompanied by the AD process. The treatment of tonifying kidneys,supplementing essence and replenishing marrow is the fundamental method for AD in TCM. Clinical studies have shown that kidney-tonifying formula can significantly improve the cognitive function and daily ability of patients with mild and moderate AD and have no obvious adverse reactions. Its mechanism of action may be related to the protection of nerves,reduction of β-amyloid (Aβ) level in the brain,inhibition of inflammatory factors activation and anti-oxidative stress. Besides reviewing the clinical and pharmacological research progress of kidney-tonifying formula for AD,this article also discusses the advantages and shortcomings of kidney-tonifying formula in the prevention and treatment of AD based on TCM theory and modern medical research. The aim of this study is to provide references of kidney nourishing therapy in TCM for the prevention and treatment of neurodegenerative diseases.

Objective:To investigate the expression of retinoic acid receptor responsive gene 2 (RARRES2), microtubule microfilament cross-linking factor 1 (MACF1), and core protein polysaccharide (DCN) in cerebrospinal fluid (CSF) of patients with neurosyphilis, and their diagnostic value for neurosyphilis.Methods:A total of 64 non neurosyphilis syphilis patients (syphilis group) and 78 neurosyphilis patients (neurosyphilis group) admitted to the Second Hospital of Nanjing between June 2020 and September 2022 were included. Among neurosyphilis patients, there were 48 early neurosyphilis patients (early group) and 30 late neurosyphilis patients (late group). Patients with neurosyphilis are treated with routine symptomatic therapy and antibiotic therapy to expel syphilis. The mRNA levels of RARRES2, MACF1, and DCN in CSF of patients with neurosyphilis before and after treatment were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the neurological function of patients with neurosyphilis before and after treatment. The diagnostic value of various indicators for neurosyphilis was analyzed using receiver operating characteristic (ROC) curves.Results:The mRNA levels of RARRES2, MACF1, and DCN in CSF of patients with neurosyphilis were higher than those in the syphilis group (all P<0.001). The mRNA levels of RARRES2, MACF1, and DCN in the CSF of patients with advanced neurosyphilis were higher than those in the early group (all P<0.001). Compared with before treatment, the NIHSS score and RARRES2, MACF1, and DCN mRNA levels of neurosyphilis patients decreased after treatment (all P<0.001). The area under the curve (AUC), sensitivity, and specificity of the combined diagnosis of RARRES2, MACF1, and DCN mRNA in CSF for neurosyphilis were 0.995%, 100.00%, and 93.75%, respectively. The AUC and sensitivity were higher than those of individual diagnosis. Conclusions:The expression of RARRES2, MACF1, and DCN is elevated in CSF of patients with neurosyphilis, and is associated with disease severity and treatment response. These three genes may be candidate biomarkers for diagnosing neurosyphilis.

Alzheimer's disease (AD) is a deleterious neurodegenerative disorder, which has become a significant public health concern and economic burden. The pathogenesis of AD is complex and involves several hypotheses such as amyloid β-protein (Aβ) deposition, Tau protein hyperphosphorylation, oxidative stress, and inflammation. There is an urgent need for a holism-based comprehensive intervention with multi-pathway, multi-level, and multi-target characteristics, which demonstrates the unique advantage of traditional Chinese medicine (TCM). Therefore, it is of great significance to conduct and promote research on TCM treatment of AD. Danggui Shaoyaosan (DSS) from the Synopsis of Golden Chamber (《金匮要略》) by ZHANG Zhongjing (150 AD-219 AD) was originally designed for reliving gynecological ailments. It is a classic TCM formula that modulates liver and spleen and dispels blood stasis and water retention. Since the late 1980s when Japanese researchers reported its therapeutic effect on AD, it has been widely used in the clinic with clear effects. The elucidation of the mechanism of this formula helps exert its effects. Hereby, this paper reviewed relative research progress and made an analysis in terms of attenuating aberrant accumulation of Aβ and hyperphosphorylated Tau protein, anti-inflammatory and antioxidant activities, mediating neurotransmitters, ameliorating lipid metabolism, modulating gut microbiota, reduced neuron apoptosis, decreasing intracellular Ca2+ overloading, and increasing the expression of estradiol. This paper is expected to provide references for understanding the scientific connotation of DDS in the treatment of AD and lay a solid foundation for further investigation.

ObjectiveTo investigate the mechanism of Danggui Shaoyaosan (DSS) in the improvement of the cognitive ability of SAMP8 mice with Alzheimer's disease (AD) via regulating the ubiquitin-proteasome pathway (UPP). MethodFifteen SAMR1 mice were used as a normal group, and 60 SAMP8 mice were randomly divided into a model group and DSS high, medium, and low-dose groups (57.6, 28.8, and 14.4 g·kg-1·d-1), with 15 mice in each group. Intragastric administration was conducted for eight continuous weeks. Place navigation and spatial capacity were evaluated by Morris water maze. Pathological structure changes in neurons in the hippocampal CA1 area was detected by hematoxylin-eosin (HE) staining. The protein expression levels of hippocampal β-amyloid protein(Aβ) and phosphorylation(p)-Tau were determined by immunohistochemical staining (IHC) and enzyme-linked immunosorbent assay (ELISA), and the mRNA and protein expression levels of hippocampal ubiquitin (Ub), ubiquitin ligase E3 (E3), 26S proteasome, ubiquitin carboxyl terminal hydrolase-1 (UCHL1), and UCHL3 were determined by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultAs compared with the normal group, the escape latency was prolonged in the model group (P<0.05) with the reduced number of crossing platform quadrants and time ratio in the platform quadrant (P<0.05). The model group decreased neurons and condensed cell bodies in the CA1 area, and increased β-amyloid precursor protein (β-APP) and p-Tau positive cells (P<0.05). In the model group, the protein expression levels of Aβ and p-Tau were increased (P<0.05), the mRNA and protein expression levels of Ub were increased (P<0.05), and the mRNA and protein expression levels of E3, 26S proteasome, UCHL1, and UCHL3 were decreased (P<0.05). As compared with the model group, the escape latency was shortened in the DSS high and medium-dose groups (P<0.05) with an increased number of crossing platform quadrants and residence time ratio (P<0.05). The pathological changes in CA1 of each DSS group were significantly improved, and the number of β-APP positive staining cells decreased (P<0.05). The number of p-Tau positive staining cells decreased in the DDS medium and low-dose groups (P<0.05). The protein expression levels of Aβ and p-Tau in each DDS group decreased (P<0.05), and the mRNA expression level of Ub in each group decreased (P <0.05). The mRNA expression levels of 26S, E3, and UCHL3 in the DDS high and medium-dose groups increased (P<0.05), and the mRNA expression level of UCHL1 in the DDS medium-dose group increased (P<0.05). The protein expression level of Ub in each DDS group decreased, and the protein expression levels of 26S, E3, UCHL1+3 in the DDS high and medium-dose groups increased (P<0.05). ConclusionDSS can improve the cognitive ability of SAMP8 mice, and its mechanism may be related to the reduction of the abnormal deposition of Aβ and p-Tau via decreasing the expression of Ub and increasing that of E3, 26S, UCHL1, and UCHL3 in the UPP.

ObjectiveTo investigate the protective effect of Danggui Shaoyaosan (DSS)-contained serum on β-amyloid (Aβ)1-40-injured rat adrenal pheochromocytoma PC12 cells and its mechanism in regulating ubiquitin-proteasome pathway (UPP). MethodAβ1-40 was used to intervene PC12 cells to prepare the cell models of Alzheimer's disease (AD), and the experiment was divided into the blank, model, and DSS-contained serum high, medium, and low-dose groups (10%, 5%, and 2.5%). Cell viability and apoptosis were detected using cell counting kit-8 (CCK-8) method and flow cytometry, respectively. The content of Aβ and p-Tau protein was determined by enzyme-linked immunosorbent assay (ELISA). The ubiquitin (Ub), ubiquitin ligase E3 (E3), 26S proteasome, ubiquitin carboxyl terminal hydrolase1 (UCHL1), and UCHL3 protein expressions of UPP were displayed using immunofluorescence cytochemistry (ICC), and the mRNA and protein expression levels of Ub, E3-parkin, 26S, UCHL1, and UCHL3 were determined by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultThe data of the CCK8 experiment verified that 5 μmol·L-1 and 48 hours were the optimal conditions for modeling Aβ1-40-injured PC12 cells. As compared with the blank group, the cell viability rate in the model group decreased (P<0.05) with an increased apoptosis rate (P<0.05), the content of Aβ and p-Tau contents was elevated (P<0.05), the mRNA and protein expression levels of Ub increased, and the mRNA and protein expression levels of 26S, E3, and UCHL1+3 decreased (P<0.05). As compared with the model group, the cell viability rate in the DSS-contained medium-dose group increased (P<0.05), whereas the apoptosis rate in each DSS-contained group decreased (P<0.05). The content of Aβ in each DDS-contained group decreased (P<0.05), and the content of p-Tau in the DDS-contained high and medium-dose groups decreased (P<0.05). The mRNA expression level of Ub decreased, and that of 26S increased in each DDS-contained group (P<0.05). The mRNA expression level of UCHL1 in the DDS-contained medium-dose group increased (P<0.05), and the mRNA expression levels of E3 and UCHL 3 in the DDS-contained high and medium-dose groups increased (P<0.05). The protein expression level of Ub in each DDS-contained group decreased, and the protein expression levels of 26S, E3, and UCHL1+3 in the DDS high and medium-dose groups increased. The DSS-contained serum medium-dose group exerted the optimal effect. ConclusionDSS-contained serum can increase cell viability rate, reduce cell apoptosis rate, eliminate Aβ and p-Tau protein deposits, and exert protective effects on Aβ1-40-injured PC12 cells. Its mechanism may involve UPP via decreasing the expression of Ub and increasing that of 26S, E3, UCHL1, and UCHL3.

ObjectiveTo analyze the effects of Danggui Shaoyaosan (DSS) on the gut microbiota of the Alzheimer's disease (AD) model in SAMP8 mice based on 16S rDNA sequencing. MethodTwenty-four SAMP8 mice aged seven months were randomly divided into low-, medium-, and high-dose DSS groups (14.4, 28.8, 57.6 g·kg-1·d-1) and a model group according to a random number table, with six rats in each group. Six SAMR1 mice of the same age were assigned to the normal group. After intragastric administration for eight consecutive weeks, 16S rDNA sequencing was performed to detect the gut microbiota of feces in mice. Morris water maze was employed to assess the directional navigation and space exploration ability of mice. Nissl staining was performed to observe the pathological changes of neurons in the hippocampal CA1 area. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure the protein content of hippocampal amyloid β-protein (Aβ) and hyperphosphorylated Tau (p-Tau). ResultCompared with the normal group, the model group presented a declining α diversity (P<0.05), markedly altered β diversity, prolonged escape latency (P<0.05), reduced number of platform crossings and cumulative duration in the targeted quadrant (P<0.05), decreased neurons and Nissl bodies in the CA1 hippocampal area, and up-regulated Aβ and p-Tau expression (P<0.05). However, DSS intervention enhanced the α diversity, and medium- and high-dose DSS, especially the medium-dose DSS, could result in α diversity similar to the control group. Moreover, at the phylum level, the abundance of Firmicutes increased (P<0.05), while the abundance of Bacteroidetes and Proteobacteria decreased (P<0.05). At the genus level, the abundance of Lactobacillus and other genera increased (P<0.05), while the abundance of Bacteroides, Helicobacterium, Rikenella, Parabacteroides, Sutterella, and Mucilaginibacter decreased (P<0.05). The DSS groups also showed shortened escape latency (P<0.05), increased number of platform crossings and cumulative duration in the targeted quadrant (P<0.05), increased Nissl bodies (P<0.05), and reduced Aβ and p-Tau content (P<0.05). Pearson correlation analysis showed that the abundance of Mucilaginibacter, Bacteroides, and Sutterella was negatively correlated with the cognitive ability of SAMP8 mice, while the abundance of Lactobacillus and Butyricimonas was positively correlated with the cognitive ability of SAMP8 mice. ConclusionDSS can improve the cognitive ability of SAMP8 mice, and its mechanism may be related to the regulation of gut microbiota diversity and community composition.

Objective:To investigate the value and influence factors of preoperative and intraoperative localization of ectopic hyperparathyroidism (EHPT).Methods:Results of 99mTc-sestamibi ( 99mTc-MIBI), neck ultrasound, contrast CT and intraoperative local venous parathyroid hormone (IOLVPTH) were retrospectively analyzed in 205 patients with primary hyperparathyroidism (PHPT) suspected of EHPT. Results:Incidence of EHPT was 16.6% (34 cases), and 36 ectopic lesions were detected. The proportion of EHPT in antero-superior mediastinum, intrathyroidal, in the retropharyngeal region, in carotid sheath, in the prevertebral region and intrapericardial were 44.1% (15 cases), 29.4% (10 cases), 11.8% (4 cases), 5.9% (2 cases), 5.9% (2 cases) and 2.9% (1 cases), respectively. Contrast CT was the most sensitive (86.1%, 31 lesions/36 lesions) for EHPT, followed by 99mTc-MIBI (66.7%, 24 lesions/36 lesions), IOLVPTH monitoring (61.8%, 21 lesions/34 lesions) and neck ultrasound (55.6%, 20 lesions/36 lesions). Contrast CT was most sensitive,100% in detecting deep-located EHPT lesions, whereas IOLVPTH had advantages in detecting intrathyroidal EHPT lesions, with a sensitivity of 100.0%.The combined use of 99mTc-MIBI and neck ultrasound showed a sensitivity of 77.8% in the localization of EHPT. Conclusions:Contrast CT is highly sensitive in the localization of EHPT. The combined use of preoperative imaging and IOLVPTH monitoring helps to higher localization for EHPT.
