ObjectiveTo observe the clinical efficacy and safety of Guben Quyu Jiedu prescription in treating nocturnal hypoxemia of chronic obstructive pulmonary disease (COPD) combined with Obstructive sleep apnea hypopnea syndrome ( OSAHS ) (deficiency of lung, spleen and kidney with blood stasis and toxicity). MethodsThe paper used a forward-looking, random double-blind, placebo-controlled design method to select 96 patients with COPD combined with OSAHS, and their traditional Chinese medicines (TCM) syndrome differentiation was deficiency of lung, spleen and kidney with blood stasis and toxicity. These patients were randomly divided into the observation group and the control group, with 48 cases in each group. Based on conventional Western medicine treatment, the observation group was treated with Guben Quyu Jiedu prescription and the control group was treated with traditional Chinese medicine placebo. Both courses of treatment were 90 days. Then the paper compared the changes in minimum pulse oxygen saturation (SpO2) during the night, apnea index (AHI), OSAHS efficacy evaluation, TCM syndrome efficacy evaluation, and TCM symptom score before and after treatment between the two groups. ResultsThere were 5 withdrawals in the observation group and 8 withdrawals in the control group, so 43 cases in the observation group and 40 cases in the control group completed the trial. Compared with the condition before treatment, the minimum SpO2 during the night and AHI in the observation group were significantly improved at night (P<0.01) and were better than those in the control group (P<0.01). OSAHS efficacy in the observation group was better than in the control group (χ2=7.085, P<0.05). In terms of TCM syndrome efficacy, the total effective rate was 81.40% (35/43) in the observation group, significantly higher than that in the control group, which was 15.00% (6/40) (χ2=36.78, P<0.01). The TCM symptom scores of the two groups were improved compared with the condition before treatment, and the effect of the two groups was similar in the four main symptoms of snoring, choking, lethargy, and cough. However, the observation group was better than the control group in 10 details such as dizziness, headache, chest tightness, chest pain, wheezing, dry mouth, and thirst (P<0.05). ConclusionUsing Guben Quyu Jiedu prescription combined with conventional Western medicine can treat COPD combined with OSAHS hypoxemia at night (deficiency of lung, spleen and kidney with blood stasis and toxicity). In this way, the minimum pulse oxygen saturation (SpO2) of patients, the level of disease control, and the quality of life of patients can be improved, and the clinical symptoms can be relieved.

ObjectiveTo study the pharmacological substances and mechanisms through which sesquiterpene ZH-13 from Aquilariae Lignum Resinatum improves neuroinflammation. MethodsBV-2 microglial cells were stimulated with lipopolysaccharide (LPS) to induce neuroinflammation. The cells were divided into the normal group, the model group, and the ZH-13 low- and high-dose treatment groups (10, 20 μmol·L-1). The model group was treated with 1 μmol·L-1 LPS. Cell viability was assessed using the cell proliferation and activity assay (CCK-8 kit). Nitric oxide (NO) release in the cell supernatant was measured using a nitric oxide kit (Griess method). The mRNA expression levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS), and interleukin-6 (IL-6) were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The phosphorylation of mitogen-activated protein kinase (MAPK) pathway proteins was assessed by Western blot. ResultsCompared with the model group, ZH-13 dose-dependently reduced NO release from BV-2 cells under LPS stimulation (P<0.05, P<0.01). In the 20 μmol·L-1 ZH-13 treatment group, the mRNA expression levels of IL-1β, TNF-α, iNOS, and IL-6 were significantly reduced compared to the model group (P<0.05, P<0.01). In both the low- and high-dose ZH-13 groups, the expression of the inflammatory factor TNF-α and the phosphorylation of c-Jun N-terminal kinase (JNK) in the upstream MAPK pathway were significantly reduced (P<0.05). After stimulation with the JNK agonist anisomycin (Ani), both low- and high-dose ZH-13 treatment groups showed reduced phosphorylation of JNK proteins compared to the Ani-treated group (P<0.01). ConclusionThe sesquiterpene compound ZH-13 from Aquilariae Lignum Resinatum significantly ameliorates LPS-induced neuroinflammatory responses in BV-2 cells by inhibiting excessive JNK phosphorylation and reducing TNF-α expression. These findings elucidate the pharmacological substances and mechanisms underlying the sedative and calming effects of Aquilariae Lignum Resinatum.

Gastric cancer is a high-incidence malignancy that poses a serious threat to public health in China, ranking among the top three cancers in both incidence and mortality. The majority of patients are diagnosed at an advanced stage, resulting in limited treatment options and poor prognosis. To address key challenges in gastric cancer diagnosis and treatment, a research team led by Professor Jiafu Ji at Peking University Cancer Hospital has focused on the project "Development and Dissemination of Precision Medicine Approaches in Gastric Cancer Management". Through a series of high-quality multicenter clinical studies, the team established a set of new international standards in perioperative treatment, individua-lized drug selection, intelligent noninvasive diagnostics, and novel immunotherapy strategies. These advances have significantly improved treatment efficacy and reduced surgical trauma, achieving key technological breakthroughs in diagnosis, therapy, and mechanistic understanding, and systematically enhancing outcomes for gastric cancer patients. The project ' s findings had a broad international impact, including hosting China ' s first International Gastric Cancer Congress. Through nationwide dissemination, they have promoted the development of precision diagnosis and treatment of gastric cancer as a discipline, and led the formulation of the National Health Commission's guidelines for gastric cancer diagnosis and treatment. In recognition of its achievements, the project was awarded the First Prize of the 2024 Chinese Medical Science and Technology Award.

ObjectiveTo explore the mechanism of Buzhong Yiqitang on pyroptosis in autoimmune thyroiditis (AIT) mice based on the NOD-like receptor hot protein domain related protein 3 (NLRP3)/cysteinyl aspartate specific proteinase-1(Caspase-1)/Gasdermin D (GSDMD) pathway. MethodSixty NOD.H-2h4 mice were divided into normal group, model group, low, medium, and high dose groups (4.10, 8.19, 16.38 g·kg-1)of Buzhong Yiqitang, and selenium yeast tablet group (0.26 mg·kg-1), with 10 mice in each group. Except for the normal group, all other groups were given 0.05% NaI by gavage for eight weeks to establish a model and then received the drug treatment for eight weeks. The serum levels of thyroid peroxidase antibody (TPO-Ab) and thyroglobulin antibody (TgAb) were detected using enzyme-linked immunosorbent assay (ELISA) method. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in mouse thyroid tissue. The immunohistochemical method was used to detect the protein expression of NLRP3, Caspase-1, interleukin-1β (IL-1β), and interleukin-18 (IL-18). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of NLRP3, Caspase-1, IL-1β, and IL-18. Western blot was used to detect the levels of pyroptosis-related proteins in thyroid tissue. ResultCompared with the normal group, the serum levels of TPO-Ab and TgAb in the model group were significantly increased (P<0.01). Thyroid follicles either increased in a cubic shape or were damaged and atrophied, with a large number of lymphocytes infiltrating around the follicles. Compared with the model group, the levels of TPO-Ab and TgAb in other groups were significantly reduced (P<0.01), and the morphology and structure of follicles were improved. The degree of lymphocyte infiltration was reduced. Among them, the medium dose group of Buzhong Yiqitang had the most significant reduction and improvement effect. Compared with the normal group, the positive products and mRNA expression of NLRP3, Caspase-1, IL-1β, and IL-18 proteins in the thyroid tissue of the model group significantly increased (P<0.01), and the protein expression levels of NLRP3, cleaved Caspase-1, IL-1β, IL-18, and GSDMD-N were significantly increased (P<0.05, P<0.01). Compared with the model group, the positive products and mRNA expression of NLRP3, Caspase-1, IL-1β, and IL-18 proteins in other groups were significantly reduced (P<0.05, P<0.01), with the most significant reduction effect in the medium dose group of Buzhong Yiqitang. The protein expression levels of NLRP3, cleaved Caspase-1, IL-1β, IL-18, and GSDMD-N were significantly reduced (P<0.05, P<0.01). ConclusionBuzhong Yiqitang can improve AIT, and its mechanism may be achieved by regulating the NLRP3/Caspase-1/GSDMD signaling pathway to inhibit pyroptosis.
