Objective To investigate the effect of berberine and its mechanism in delaying silica-induced lung injury via network pharmacology and molecular docking, followed by verification with animal experiments. Methods i) Targets of berberine and silicosis were obtained from multiple databases, and the common targets were identified. A protein-protein interaction network was constructed using the STRING database, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on the common targets via the DAVID database. Molecular docking was conducted using AutoDock software for validation. ii) Specific pathogen-free Wistar rats were randomly divided into five groups, with six rats in each group. Rats in the model group, pirfenidone group, and low- and high-dose berberine groups received a single non-exposure intratracheal instillation of 1.00 mL silica suspension at a mass concentration of 100 g/L, whereas rats in the control group received an equal volume of 0.9% sodium chloride solution. Rats in the pirfenidone group were administered with pirfenidone solution at a dose of 100 mg/kg body weight, and rats in the low- and high-dose berberine groups were administered with berberine solutions at doses of 100 and 200 mg/kg body weight, respectively. The remaining two groups received equal volumes of 0.9% sodium chloride solution. All treatments were administered by gavage once daily for 28 consecutive days from 24 hours after silica exposure. After intervention, rats in each group were sacrificed. Histopathological changes in lung tissues were observed, and the lung organ coefficient was detected. Serum malondialdehyde (MDA) was detected by colorimetry. Serum inflammatory cytokine were detected by enzyme-linked immunosorbent assay. The expression of fibrosis markers in lung tissues was detected by immunohistochemistry. The protein expression of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), and phosphorylated AKT (p-AKT) in lung tissues was determined by Western blot. Results i) Network pharmacology analysis identified 46 potential targets. The core targets included AKT1, tumor protein p53, caspase-3, matrix metalloproteinase-9, and albumin. GO enrichment analysis revealed that the targets related to the anti-fibrotic effect of berberine against silicosis were mainly enriched in biological processes including signal transduction, negative regulation of apoptosis, extracellular matrix degradation, and response to reactive oxygen species. KEGG enrichment analysis showed that berberine exerted anti-silicosis effects through multiple signaling pathways, such as the PI3K/AKT pathway, hypoxia-inducible factor-1 pathway, and advanced glycation end product (AGE)-receptor for AGE pathway. ii) Histopathological examination revealed that rats in the model group presented typical pulmonary fibrotic lesions. Pathological lung injury of rats was alleviated in all three intervention groups (pirfenidone group, low- and high-dose berberine group) compared with the model group. The improvement in the high-dose berberine group was superior to that in the low-dose berberine group and was comparable with that in the pirfenidone group. rats in the model group showed increased lung organ coefficient, serum MDA, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) (all P<0.05), as well as increased expression of typeⅠcollagen (COLⅠ), α-smooth muscle actin (α-SMA) and PI3K, and p-AKT/AKT ratio in lung tissues (all P<0.05) when compared with the control group. The above indicators were lower in rats in both the low- and high-dose berberine groups than those in the model group (all P<0.05). Serum MDA, IL-1β, and TNF-α, as well as relative expression of COLⅠ and α-SMA in lung tissues, were lower in the high-dose berberine group than in the low-dose berberine group (all P<0.05). Conclusion Berberine may alleviate pulmonary inflammation and fibrosis in rats through regulation of the PI3K/AKT signaling pathway, thereby delaying the progression of silicosis.

Purpose To investigate the clinicopathological features,diagnosis,differential diagnosis,treatment,and prognosis of intrathyroid thymic carcinoma(ITC).Methods The clinical manifestations,histological features and immunophenotypes of 11 patients with ITC were retrospectively analyzed.Immunohistochemistry and Sanger sequencing were used for protein and gene detection.The relevant literature is retrieved and the data of this paper is analyzed sta-tistically.Results Among the 11 patients,6 were female and 5 was male,aged from 35 to 75 years old.Tumor inva-sion into peripheral thyroid tissue was observed in 2 cases.Immunohistochemical analysis revealed positive expression for CD5,CD117,p63,p40,CK5/6,CK17 and CKpan,with focal positivity for Syn observed in only 1 case.Genetic testing:1 patient had mutations in the TERT promoter gene(C.-228 C＞T).Conclusion ITC is an extremely rare,low-grade malignant tumor.Due to its morphological similarity to other highly malignant thyroid tumors,it is prone to misdiagnosis.Immunohistochemistry and genetic testing play a crucial role in accurate differential diagnosis.

Objective:Varicocele(VC)induces male infertility by mediating changes in the testicular microenvironment,in which testicular hypoxia and high-pressure are important pathological conditions.This study aims to compare the mouse spermatogenesis(GC-2spd)cells and Sertoli(TM4)cells of mouse testis after hypoxic modeling and hypoxic and high-pressure combined modeling,and to explore the feasibility of establishing a hypoxic and high-pressure combined cell model.Methods:On the basis of cell hypoxia induced by CoCl2,the complex model of testicular cell hypoxia and high pressure was constructed by changing the osmotic pressure of GC-2 and TM4 cell medium with a high concentration of NaCl solution.After selecting the intervention concentration of CoCl2 by MTT test and detecting the expression level of HIF-1α for the determination of the optimal osmotic pressure conditions of the cell model,the cells were divided into normal group,hypoxia model group and composite model group.And the levels of OS,programmed cell death,inflammatory factors,and the expression levels of pyroptosis-related proteins were compared between the normal group and the groups with different modeling methods.Results:The optimal intervention concentration of CoCl2 in GC-2 and TM4 cells was 150 and 250μmol/L,respectively,and the expression of HIF-1α was the highest in both cells under osmotic pressure of 500 mOsmol/kg(P＜0.05).Compared with the normal group,the SOD levels of GC-2 and TM4 cells decreased(all P＜0.05),CAT level decreased(all P＜0.05),and MDA level increased(all P＜0.01),and the OS level of GC-2 and TM4 cells was more obvious than that of the hy-poxia model group(all P＜0.05).Compared with the normal group,apoptosis occurred in GC-2 and TM4 cells after composite model-ing(all P＜0.05).Compared with the normal group,the mRNA expressions of IL-1β,IL-18,TNF-α and COX-2 in GC-2 and TM4 cells significantly increased(P＜0.01)and higher than those in hypoxia model group(P＜0.05)and induced pyroptosis(P＜0.01).The expression level of GSDMD increased(P＜0.05).Conclusion:The cell model with hypoxia and high pressure com-bined modeling can not only induce oxidative stress and apoptosis of cells better than that with hypoxia alone,but also further cause in-flammatory response damage and pyroptosis,which simulates the changes of testis microenvironment mediated by hypoxia and high pressure combined conditions in VC.This cell model can be used for studying the pathogenesis of VC-associated male infertility,evalu-ating drug efficacy,and exploring pharmacological mechanisms.
