ObjectiveTo investigate the mechanism of action of Kaixinsan in the treatment of Alzheimer's disease (AD) based on network pharmacology, molecular docking, and animal experimental validation. MethodsThe Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and the Encyclopedia of Traditional Chinese Medicine(ETCM) databases were used to obtain the active ingredients and targets of Kaixinsan. GeneCards, Online Mendelian Inheritance in Man(OMIM), TTD, PharmGKB, and DrugBank databases were used to obtain the relevant targets of AD. The intersection (common targets) of the active ingredient targets of Kaixinsan and the relevant targets of AD was taken, and the network interaction analysis of the common targets was carried out in the STRING database to construct a protein-protein interaction(PPI) network. The CytoNCA plugin within Cytoscape was used to screen out the core targets, and the Metascape platform was used to perform gene ontology(GO) functional enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis. The “drug-active ingredient-target” interaction network was constructed with the help of Cytoscape 3.8.2, and AutoDock Vina was used for molecular docking. Scopolamine (SCOP) was utilized for modeling and injected intraperitoneally once daily. Thirty-two male C57/BL6 mice were randomly divided into blank control (CON) group (0.9% NaCl, n=8), model (SCOP) group (3 mg·kg-1·d-1, n=8), positive control group (3 mg·kg-1·d-1 of SCOP+3 mg·kg-1·d-1 of Donepezil, n=8), and Kaixinsan group (3 mg·kg-1·d-1 of SCOP+6.5 g·kg-1·d-1 of Kaixinsan, n=8). Mice in each group were administered with 0.9% NaCl, Kaixinsan, or Donepezil by gavage twice a day for 14 days. Morris water maze experiment was used to observe the learning memory ability of mice. Hematoxylin-eosin (HE) staining method was used to observe the pathological changes in the CA1 area of the mouse hippocampus. Enzyme linked immunosorbent assay(ELISA) was used to determine the serum acetylcholine (ACh) and acetylcholinesterase (AChE) contents of mice. Western blot method was used to detect the protein expression levels of signal transducer and activator of transcription 3(STAT3) and nuclear transcription factor(NF)-κB p65 in the hippocampus of mice. ResultsA total of 73 active ingredients of Kaixinsan were obtained, and 578 potential targets (common targets) of Kaixinsan for the treatment of AD were screened out. Key active ingredients included kaempferol, gijugliflozin, etc.. Potential core targets were STAT3, NF-κB p65, et al. GO functional enrichment analysis obtained 3 124 biological functions, 254 cellular building blocks, and 461 molecular functions. KEGG pathway enrichment obtained 248 pathways, mainly involving cancer-related pathways, TRP pathway, cyclic adenosine monophosphate(cAMP) pathway, and NF-κB pathway. Molecular docking showed that the binding of the key active ingredients to the target targets was more stable. Morris water maze experiment indicated that Kaixinsan could improve the learning memory ability of SCOP-induced mice. HE staining and ELISA results showed that Kaixinsan had an ameliorating effect on central nerve injury in mice. Western blot test indicated that Kaixinsan had a down-regulating effect on the levels of NF-κB p65 phosphorylation and STAT3 phosphorylation in the hippocampal tissue of mice in the SCOP model. ConclusionKaixinsan can improve the cognitive impairment function in SCOP model mice and may reduce hippocampal neuronal damage and thus play a therapeutic role in the treatment of AD by regulating NF-κB p65, STAT3, and other targets involved in the NF-κB signaling pathway.

Objective:
To investigate whether fibroblast growth factor 18(FGF18) can induce human gingival fibroblasts(HGFs) isolatedin vitroto differentiate into osteoblast-like cells, and to explore the mechanism of osteogenesis.
Methods :
HGFs were isolated, cultured and identified by tissue block method. The third generation of HGFs were divided into experimental group and control group. FGF18 and L-DMEM was added to the experimental group while L-DMEM was added to the control group.The effects of different concentrations of FGF18(0, 0.01, 0.02, 0.04, 0.06 mg/L) on proliferation of HGFs were detected by Methylthiazolyldiphenyl-tetrazolium bromide(MTT) assay. Alkaline phosphatase(ALP) and alizarin red staining were used to detect the osteogenesis and mineralization ability of the cells after induction. RT-PCR, immunocytochemistry staining, and Western blot were used to detect the expression of genes and proteins related to osteogenesis and BMP2 in the BMP signaling pathway.
Results:
Compared with the control group, the experimental group could promote the proliferation of HGFs at 3, 5, 7, 9, and 11days(P<0.05),ALP activity and mineral salt deposition increased after induction at 14 and 21 days(P<0.05), and the expressions of ALP, OPN, OCN mRNA and BMP2 mRNA in BMP signaling pathway significantly increased(P<0.01). The expressions of OPN, OCN and BMP2 protein at 21 days were significantly higher than those at 14 days(P<0.01).
Conclusion
FGF18 can promote the proliferation of HGFs, and induce the differentiation of HGFs into functional osteoblasts. The osteogenic mechanism is related to the upregulation of BMP2.

Objective:To analyze the clinicopathological characteristics and prognostic factors of patients with Castleman disease (CD).Methods:A retrospective case-series study was conducted. A total of 85 patients newly diagnosed with CD in the First Affiliated Hospital of Air Force Medical University between July 2007 and August 2024 were collected. Their clinical characteristics and prognostic factors were analyzed.Results:Among the 85 patients, 45 had unicentric Castleman disease (UCD) and 40 had multicentric Castleman disease (MCD). In the UCD group, females were more commonly affected (64.4%, 29/45), with a median age of onset of 39 years. The primary lesions were mainly located in the retroperitoneum, neck, abdomen, and axilla; and the hyaline vascular subtype was the predominant pathological type (69.4%, 25/36). In the MCD group, males were more frequently affected (62.5%, 25/40), with a median age of onset of 50 years; and the plasmacytic subtype was the main pathological type (68.2%, 15/22). Compared with UCD patients, MCD patients presented more systemic symptoms and signs [85.0% (34/40) vs. 13.3% (6/45), χ2 = 43.66, P < 0.001], splenomegaly [42.5% (17/40) vs. 2.2% (1/45), χ2 = 20.58, P < 0.001], hepatomegaly [25.0% (10/40) vs. 0 (0/45), χ2 = 10.46, P = 0.001], edema or effusion in serous cavity [67.5% (27/40) vs. 8.9%(4/45), χ2 = 31.40, P < 0.001], hematological system involvement [32.5% (13/40) vs. 0 (0/44), χ2 = 16.92, P < 0.001], and renal involvement [22.5% (9/40) vs. 2.3%(1/44), χ2 = 6.36, P = 0.012]. Laboratory findings showed that the levels of hemoglobin and albumin in MCD patients were lower than those in UCD patients, while white blood cell count in MCD patients was higher than that in UCD patients. Additionally, MCD patients exhibited elevated levels of C-reactive protein, interleukin-6, vascular endothelial growth factor, erythrocyte sedimentation rate, and ferritin compared to UCD patients (all P < 0.05). Among UCD patients, 40 cases underwent simple surgical resection, with no deaths during follow-up and the 5-year overall survival (OS) rate of 100.0%; among MCD patients, 34 cases received chemotherapy, 4 received siltuximab, 3 died during follow-up with a 5-year OS rate of 87.5%; and there was no statistically significant difference in OS between the MCD and UCD groups ( χ2 = 3.67, P = 0.055). Among MCD patients, the OS of those with renal involvement (9 cases) was worse than that of those without renal involvement (31 cases) ( χ2 = 8.39, P = 0.004). Conclusions:CD is a highly heterogeneous disorder. Surgical resection is the primary treatment for UCD, with a favorable prognosis. Chemotherapy is the main treatment for MCD, with a relatively poor prognosis.
