ObjectiveTo investigate the effects of Yishen Juanbi pills （YSJB）-containing bone marrow fluid on the migration and differentiation phenotypes of CD4⁺T lymphocytes based on the stromal cell-derived factor-1/chemokine receptor 4 （SDF-1/CXCR4） signaling pathway. MethodsPrimary CD4⁺T lymphocytes were isolated from mice using magnetic bead separation and identified for purity by flow cytometry. A CD4⁺T lymphocyte culture system was then established to observe the effects of SDF-1 on CD4⁺T-cell migration and differentiation. On this basis， the experimental groups included the Sham group， the ovariectomy （OVX） group， the Sham+collagen-induced arthritis （CIA） group， the OVX+CIA group， the Sham+CIA+YSJB group （2.16 g·kg^-1）， the OVX+CIA+YSJB group （2.16 g·kg^-1）， and the OVX+CIA+methotrexate （MTX） group （1.5 mg·kg^-1）. Bone marrow fluid from each group was prepared according to previous methods and added to the CD4⁺ T-cell culture system at 5% （v/v）. Transwell assays were used to examine CD4⁺T-cell migration in each group. Real-time PCR was used to measure the mRNA expression levels of interleukin （IL）-17， tumor necrosis factor-α （TNF-α）， retinoic-acid-related orphan receptor γt （RORγt）， IL-10， transforming growth factor-β （TGF-β）， forkhead box P3 （FoxP3）， CXCR4， phosphoinositide 3-kinase （PI3K）， and protein kinase B （Akt）. Western blot was used to detect the expression of helper T （Th）17/regulatory T （Treg） cell signature factors （RORγt， FoxP3）， CXCR4， PI3K， phosphorylated （p）-PI3K， Akt， and p-Akt. In a separate set of experiments， cells were divided into the Sham group， OVX+CIA group， OVX+CIA+CXCR4 antagonist AMD3100 group， and OVX+CIA+YSJB+AMD3100 group to observe changes in the above indicators following AMD3100 intervention. ResultsCompared with the Sham group， the number of migrated cells in the lower chamber was significantly increased in the Sham+CIA and OVX+CIA groups （P<0.05， P<0.01）. The mRNA expression of RORγt， IL-17， TNF-α， CXCR4， PI3K， and Akt was significantly upregulated， whereas FoxP3， IL-10， and TGF-β mRNA expression was significantly decreased （P<0.05， P<0.01）. Protein expression of RORγt， CXCR4， p-PI3K/PI3K， and p-Akt/Akt was significantly increased， while FoxP3 protein expression was markedly decreased （P<0.05， P<0.01）. Compared with the OVX+CIA group， the OVX+CIA+YSJB group and OVX+CIA+MTX group showed significantly reduced migration （P<0.05）， mRNA expression of RORγt， IL-17， TNF-α， CXCR4， PI3K， and Akt was also significantly decreased， while FoxP3， IL-10， and TGF-β mRNA expression was significantly increased （P<0.05， P<0.01）. RORγt protein expression was significantly downregulated， and FoxP3 protein expression markedly upregulated （P<0.05）. In the OVX+CIA+YSJB group， CXCR4， p-PI3K/PI3K， and p-Akt/Akt protein expression was significantly decreased （P<0.05）. Compared with the OVX+CIA group， RORγt， CXCR4， PI3K， and Akt mRNA expression in CD4⁺T cells was significantly decreased in the OVX+CIA+AMD3100 group and the OVX+CIA+YSJB+AMD3100 group， while FoxP3 mRNA and protein expression was significantly upregulated （P<0.05， P<0.01）. RORγt， CXCR4， p-PI3K/PI3K， and p-Akt/Akt protein expression was also markedly decreased （P<0.05， P<0.01）. Compared with the OVX+CIA+AMD3100 group， the OVX+CIA+YSJB+AMD3100 group showed significantly decreased RORγt and Akt mRNA expression （P<0.05） and significantly lower p-Akt/Akt protein expression （P<0.05）. ConclusionYSJB-containing bone marrow fluid suppresses CD4⁺T-cell migration and regulates Th17/Treg balance by downregulating Th17-associated signature factors and upregulating Treg-associated signature factors through inhibition of the SDF-1/CXCR4 signaling pathway and PI3K/Akt signaling pathway. The SDF-1/CXCR4 signaling pathway is one of the targets through which YSJB inhibits CD4⁺T-cell differentiation.

Hepatic fibrosis is a pathological repair response of the liver to various chronic injuries, commonly seen in chronic liver diseases such as viral hepatitis, alcoholic liver disease, non-alcoholic fatty liver disease, etc. Hepatic fibrosis is a necessary stage for the development of chronic liver disease into cirrhosis or even hepatocellular carcinoma. Reversing or delaying the progression of hepatic fibrosis is crucial for the treatment of chronic liver disease, but there are currently no safe and effective therapeutic drugs in clinical practice. In recent years, research has found that many alkaloids in traditional Chinese medicine have anti-fibrotic activity, and their mechanisms involved multiple aspects such as cell autophagy, antioxidation, and anti-inflammation. The anti-fibrotic effects and mechanisms of alkaloids from traditional Chinese medicine were reviewed, which could provide reference for the application of alkaloids in the prevention and treatment of hepatic fibrosis.

ObjectiveTo construct a new quality classification method for Ophiopogonis Radix by systematically quantifying and integrating its appearance traits and bioactive components as objective indicators according to the theory of excellent shape， high quality， and superior effect of authentic medicinal materials. MethodsWith Ophiopogonis Radix from Zhejiang （a traditionally recognized authentic variety） as the research model， extensive samples were collected. Through textual research on classical herbal literature and modern references， root tuber length and hardness were selected as representative indicators of traditional appearance traits. These indicators were accurately measured by a digital vernier caliper and a universal testing machine for objective quantification. According to prescription data and literature review results， total saponins， total polysaccharides， and total flavonoids were chosen as key component indicators， and their content was determined. Descriptive statistics， cluster analysis， and other methods were comprehensively employed to identify the core objective indicators and their threshold ranges defining the excellent shape and high quality. The constructed evaluation system was subsequently applied to Ophiopogonis Radix from Zhejiang and Sichuan to verify its applicability. ResultsThe core quantitative indicators for the excellent shape and high quality of Ophiopogonis Radix were determined as follows： Length≥2.09 cm， hardness≤7.0 N， and content of total saponins， total polysaccharides， and total flavonoids not lower than 0.12%， 1.69%， and 0.13%， respectively. Verification results showed that this evaluation system could effectively identify Ophiopogonis Radix samples from Zhejiang， with the results consistent with traditional high-quality recognition. Its successful application to the samples from Sichuan further confirmed its cross-region universality. ConclusionThis study established an objective indicator-based evaluation system for the excellent shape and high quality of Ophiopogonis Radix， which breaks through the reliance on production regions. This system provides theoretical and methodological bases for precise quality control， scientific grading， and quality-based pricing of Ophiopogonis Radix， offering an innovative paradigm for the objective evaluation of authentic medicinal materials.

Rheumatic diseases,as a complex class of chronic immune-mediated disorders,involve interplay among genetics,environment,and immunity in their pathogenesis,which remains incompletely elucidated to date.In recent years,with the advancement of epigenetic research,particularly in the field of RNA modifications,the role of m6 A methylation in rheumatic diseases has increasingly garnered attention.Traditional Chinese medicine(TCM),as the indigenous medical system of China,has accumulated extensive experience in the treatment of rheumatic diseases.This article systematically reviewed the research progress of TCM in treating rheumatic diseases such as rheumatoid arthritis,systemic lupus erythematosus,Sj?gren's syndrome,ankylosing spondylitis,and osteoarthritis,as well as improving bone metabolism abnormalities closely related to rheumatic diseases,through regulating m6 A methylation.The aim is to provide novel insights into the treatment of rheumatic diseases with TCM and to offer theoretical support for the development of related functional drugs.

Objective:To investigate the predictive value of systemic immune inflammation index for the efficacyof neoadjuvant chemotherapy in triple negative breast cancer patients, and analyzed the relationship between pathological complete response (pCR) and prognosis.Methods:The clinical data of 146 patients with triple-negative breast cancer admitted to the 926th Hospital of the Joint Service Support Force of the PLA from January 2018 to December 2020 were retrospectively collected. All patients received neoadjuvant chemotherapy. After chemotherapy, the patients were divided into pCR group (62 cases) and non-pCR group (84 cases) according to whether the patients achieved pCR. Pathological characteristics and systemic immunoinflammatory index levels of the two groups were compared. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of systemic immunoinflammatory index for pCR after neoadjuvant chemotherapy in patients with triple-negative breast cancer, and survival curves were drawn to compare the disease-free survival of the two groups.Results:The rate of axillary lymph node metastasis in pCR group was lower than that in non-pCR group: 37.10% (23/62) vs. 64.29% (54/84), there was statistical difference ( χ2 = 10.58, P<0.01). There were no significant differences in TNM stage, Ki-67 level and histological grade between the two groups ( P>0.05). Compared with the non -pCR group, the systemic immune inflammation index in the pCR group was significantly reduced: 617.42 ± 166.40 vs. 853.67 ± 202.41, P<0.01. Systemic immune inflammation index was valuable in predicting non-pCR of triple negative breast cancer patients after neoadjuvant chemotherapy, and the area under the curve was 0.807 (95% CI: 0.738 - 0.875, P<0.01). Compared with the non-pCR group, the disease-free survival of patients in the pCR group was significantly prolonged ( P = 0.033). Conclusions:Systemic immune inflammation index was related to the efficacy of neoadjuvant chemotherapy in triple negative breast cancer patients, and can be used as a biological indicator to predict the efficacy of neoadjuvant chemotherapy in triple negative breast cancer.
