RESUMO

Chinese patent medicine (CPM) is a typical type of traditional Chinese medicine (TCM) preparation that uses Chinese herbs as raw materials and is an important means of treating diseases in TCM. Chinese patent medicine instructions (CPMI) serve as a guide for patients to use drugs safely and effectively. In this study, we apply a pre-trained language model to the domain of CPM. We have meticulously assembled, processed, and released the first CPMI dataset and fine-tuned the ChatGLM-6B base model, resulting in the development of CPMI-ChatGLM. We employed consumer-grade graphics cards for parameter-efficient fine-tuning and investigated the impact of LoRA and P-Tuning v2, as well as different data scales and instruction data settings on model performance. We evaluated CPMI-ChatGLM using BLEU, ROUGE, and BARTScore metrics. Our model achieved scores of 0.7641, 0.8188, 0.7738, 0.8107, and - 2.4786 on the BLEU-4, ROUGE-1, ROUGE-2, ROUGE-L and BARTScore metrics, respectively. In comparison experiments and human evaluation with four large language models of similar parameter scales, CPMI-ChatGLM demonstrated state-of-the-art performance. CPMI-ChatGLM demonstrates commendable proficiency in CPM recommendations, making it a promising tool for auxiliary diagnosis and treatment. Furthermore, the various attributes in the CPMI dataset can be used for data mining and analysis, providing practical application value and research significance.

RESUMO

SCOPE: This study aims to evaluate the therapeutic efficacy and mechanisms of Lycium barbarum polysaccharide (LBP) in primary Sjögren's syndrome (pSS). METHODS AND RESULTS: Non-obese diabetic mice (the pSS model) are randomly divided into four groups: Low dose LBP (LBP.L, 5 mg kg-1  d-1 ), high dose LBP (10 mg kg-1  d-1 ), low dose interleukin (IL)-2 (25 000 IU/d), and control (saline water). Drugs were treated for 12 weeks. LBP.L significantly reduces the salivary gland inflammation compared with the control group (histological score p LBP.L vs Control  = 0.019; foci number: p LBP.L vs Control  = 0.038). LBP.L also remarkably reduces the effector follicular helper T (Tfh) cells and the CD4+ IL-17A+ helper T (Th17) cells in both spleen and cervical lymph node (cLN) cells. Additionally, the ratios of regulatory T cell (Treg)/Tfh cells and Treg/Th17 cells are substantially increased in mice treated with LBP.L in both spleen and cLNs. LBP also inhibits Th17 and Tfh cells and markedly increases the Treg/Tfh ratio in human peripheral blood mononuclear cells. CONCLUSION: LBP.L inhibits the progression of pSS in mice, associated with modulation of T cell differentiation.

RESUMO

BACKGROUND: The combination of radiotherapy (RT) and chemotherapy, as a standard treatment for breast cancer in the clinic, is unsatisfactory due to chemoradioresistance and severe side effects. METHODS AND RESULTS: To address these issues, a cancer cell-erythrocyte hybrid membrane-coated doxorubicin (DOX)-loaded gold nanocage (CM-EM-GNCs@DOX) was constructed for near-infrared light (NIR)-activated photothermal/radio/chemotherapy of breast cancer. CM-EM-GNCs@DOX inherited an excellent homologous target ability from the cancer cell membrane and an immune evasion capability from the erythrocyte membrane, together resulting in highly efficient accumulation in the tumor site with decreased clearance. Following the highly efficient uptake of CM-EM-GNCs@DOX in cancer cells, the RT efficacy was remarkably amplified due to the radiosensitization effect of CM-EM-GNCs@DOX, which reduced the needed radiotherapeutic dose. Importantly, with NIR irradiation, CM-EM-GNCs@DOX exerted a high photothermal effect, which not only ruptured CM-EM-GNCs@DOX to release DOX for precise and controllable chemotherapy, but also potentiated chemo/radiotherapy by photothermal therapy. CONCLUSION: Therefore, a highly efficient and safe combined photothermal/radio/chemotherapy approach was achieved in vitro and in vivo by CM-EM-GNCs@DOX, which provided a promising strategy for treating breast cancer.
