ObjectiveTo explore the role of the histone deacetylase Sirtuin-1 （SIRT1）/p53 signaling pathway in promoting apoptosis of non-small cell lung cancer cells （NSCLC） induced by the co-stimulatory molecule B7 homolog 3 （B7-H3）. MethodsThe GEPIA 2 platform was used for survival analysis of NSCLC patients based on B7⁃H3 gene expression levels. The Gene Enrichment Analysis （GSEA） method was used to analyze the enrichment characteristics of B7⁃H3 molecules in the gene set of cell apoptosis. In the non-small cell lung cancer A549 cell line， B7⁃H3 was knocked down， and the protein expression levels of SIRT1 and p53 were detected by Western blot. B7⁃H3 was overexpressed in A549 cells and the apoptosis rate was analyzed by flow cytometry after Annexin V/PI double staining. Overexpression of B7⁃H3 and knockdown of SIRT1 were performed in A549 cell line. The expression levels of p53 and apoptosis-related proteins B-cell lymphoma/leukemia-2 （Bcl-2） and Bcl-2-associated X protein （Bax） were detected respectively by Western blot. Cell apoptosis rate was analyzed by flow cytometry after Annexin V/PI double staining. ResultsThe overall survival of the B7-H3 high-expression group was significantly lower than that of the low-expression group （P<0.01）. B7-H3 was significantly enriched in the cell apoptosis signaling pathway and the p53 signaling pathway （P<0.05）. Compared with the control group， the expression of SIRT1 was significantly downregulated， and p53 was significantly upregulated in the B7⁃H3 knockdown group （both P<0.001）. Overexpression of B7-H3 significantly up-regulated SIRT1 protein expression （P<0.05）， down-regulated p53 expression （P<0.01）， and markedly increased the Bcl-2/Bax ratio of apoptosis-related proteins （P<0.001）. The results of Annexin V/PI double staining showed that the apoptosis rate of A549 cells with overexpressed B7⁃H3 decreased （the apoptosis rate of the control group was 26.72%±4.13%， while that of the B7⁃H3 overexpression group was 13.87%±0.82%； P<0.01）. In B7-H3-overexpressing cell lines， SIRT1 knockdown significantly reversed apoptosis （P<0.05）， up-regulated p53 protein expression （P<0.001）， and markedly reduced the Bcl-2/Bax ratio （P<0.001）. ConclusionB7-H3 molecule inhibits the apoptosis of non-small cell lung cancer cells via the SIRT1/p53 signaling pathway.

Twenty-five pieces of best evidence were summarized across 8 aspects: multidisciplinary collaboration, influencing factors, assessment and monitoring, diagnostic differentiation, symptom management, dietary nutrition, medication guidance, and health education. Conclusion: Summarizing the relevant evidence on the management of patients with gastrointestinal graft-versus-host disease after hematopoietic stem cell transplantation can provide evidence-based support for clinical medical staff, and it is recommended to apply it in combination with clinical practice and patient wishes.

Objective : To investigate the effects of microRNA-29a(miR-29a) in mediating the regulation of dihydroartemisinin(DHA) on the immune checkpoint molecule B7H3 in lung adenocarcinoma(LUAD). Methods: The expression level and prognostic significance of B7H3 in LUAD were analyzed by public database. Small interfering RNA(siRNA) was used to knock down B7H3 in LUAD cell lines A549 and HCC827, and cell proliferation was detected by CCK-8 method. A549 and HCC827 cells were treated with gradient concentrations of DHA(0, 5, 10, 25, 50, 100 μmol/L) for 48 h, and the half maximal inhibitory concentrate(IC50) was calculated. A549 and HCC827 cells were treated with IC50concentration of DHA for 1, 2 and 3 days, and the cell proliferation was detected by CCK-8 method. A549 and HCC827 cells were transfected with miR-29a inhibitor. After DHA treatment, the expression level of miR-29a was detected by RT-qPCR, and the expression level of B7H3 was detected by Western blot. Results : B7H3 was overexpressed in LUAD and associated with poor prognosis. After knocking down of B7H3, the proliferation ability of A549 and HCC827 cells significantly decreased(allP<0.001). DHA inhibited the proliferation of A549 and HCC827 cells in both dose-and time-dependent manners, with IC50values of 30.16 μmol/L and 7.50 μmol/L, respectively. DHA up-regulated the expression of miR-29a in A549 and HCC827 cells(P<0.001,P<0.01), and down-regulated the expression of B7H3 in both cell lines(P<0.01,P<0.001). After transfection of miR-29a inhibitor into A549 and HCC827 cells, the expression of B7H3 was up-regulated, and the down-regulation of B7H3 by DHA was partially reversed. Conclusion miR-29a mediates the molecular regulation of DHA on B7H3 in LUAD.

Objective : To establish an enzyme-linked immunosorbent assay (ELISA) for exosome B7-H3 in plas- ma , and to explore the clinical significance and diagnostic value of exosome B7-H3 in plasma from non-small cell lung cancer (NSCLC) . Methods : The plasma of 70 NSCLC patients (NSCLC group) and 36 healthy controls (HC group) were collected . Exosomes and microvesicles in plasma were separated by ultra-fast centrifuge method , and the expression levels of B7-H3 in plasma exosomes in NSCLC groups and HC groups were compared by Western blot method . In NSCLC group , the expression levels of B7-H3 in plasma exosomes and microvesicles in NSCLC group were compared . A simple and feasible ELISA method was established to detect the expression level of exosome B7 - H3 in plasma by means of polyethylene glycol (PEG) precipitation and its clinical significance was analyzed .

Combined de- tection of exosome B7-H3 and CEA (AUC = 0. 928 , 95% CI:0. 877 - 0. 979) had a higher diagnostic performance for NSCLC . Conclusion B7-H3 in plasma exosomes is related to the cancer staging of NSCLC , and the combined detection of exosome B7-H3 and CEA in plasma is conducive to the laboratory diagnosis of NSCLC .

Objective: To investigate the role of murine double minute 2(MDM2) in dihydroartemisinin′s(DHA) inhibition of lung adenocarcinoma cell proliferation and migration. Methods: CCK8 assay was used to detect the inhibitory effect of gradient concentrations of DHA(0, 5, 10, 25, 50 and 100 μmol/L) and time gradients(0, 24, 48, and 72 h) on the proliferation of lung adenocarcinoma A549 and PC9 cells, and the half maximal inhibitory concentrate(IC50) were calculated respectively. Colony formation and scratch assays were used to detect the inhibitory effects of DHA on colony formation and migration of A549 and PC9 cells. Western blot was used to detect the inhibitory effects of DHA on MDM2 expression and epithelial-mesenchymal transition(EMT)-related proteins E-cadherin and N-cadherin. The promoting effects of MDM2 on proliferation, migration and EMT of lung adenocarcinoma cells were verified by small interfering RNA-mediated knockdown of MDM2(si-MDM2). The reversal effects of MDM2 overexpression on DHA′s inhibition on the proliferation and migration of A549 and PC9 cells were observed. Results: DHA inhibited the proliferation of A549 and PC9 cells in a dose⁃ and time⁃dependent manner,with IC50 values of 30. 57 and 78. 61 μmol/L , respectively. Compared with the Control group , A549 and PC9 cells had significantly decreased colony formation (both P < 0. 01) and migration (both P < 0. 01) upon treatment with DHA. Moreover, DHA significantly inhibited the protein expression levels of MDM2 and N ⁃cadherin in A549 and PC9 cells , and upregulated the expression of E ⁃cadherin protein (both P < 0. 05) . Compared with si⁃Control ,si⁃MDM2 significantly inhibited the protein levels of MDM2 and N ⁃cadherin in A549 and PC9 cells , and upregulat⁃(both P < 0. 01) of both cells. After overexpression of MDM2 in A549 and PC9 cells , the proliferation and migra⁃ tion ability were significantly enhanced (both P < 0. 05) , and the inhibitory effects of DHA were partially reversed by MDM2 overexpression (both P < 0. 05) . Conclusion DHA effectively inhibits the proliferation and migration of lung adenocarcinoma cells , and its mechanism is associated with the suppression of MDM2.

Background: Viral hepatitis causes annual deaths of 1.4 million people. Antiviral therapy rarely cures the disease, and patients are usually required to maintain lifelong medication, leading to cumulative drug toxicity. Schisandrae Fructus (SF) is efficacious in the treatment of viral hepatitis. Objective: The systematic review and meta-analysis aim to examine the efficacy and safety of SF alone or in combination with specific and nonspecific treatments for treating viral hepatitis by analyzing the clinical trials performed up to date. Methods: An extensive literature was searched in 7 databases from inception to May 2023. Final outcomes were divided into the primary outcomes containing the total effective rate and virological responses, as well as the secondary outcomes containing liver biochemical functions and frequencies of adverse events. RevMan 5.3 and GRADE pro 3.6 software were used for meta-analysis and assessment of evidence quality. Subgroup analysis was conducted to explore the source of the heterogeneity. Results: Twenty-nine randomized controlled trials were included in the meta-analysis. SF treatment was comparable with western medicines or other traditional Chinese treatments in terms of primary and secondary outcomes. In combination with specific treatments with antiviral medicines, SF group reduced 18.45 U/L of alanine aminotransferase levels [weighted mean difference: 18.45, 95% confidence interval (CI): (16.12, 20.78), p < 0.000 01] and 8.37 U/L of aspartate aminotransferase levels [weighted mean difference: 8.37, 95% CI: (1.25, 15.48), p = 0.02], and it decreased the levels of hyaluronic acid (HA) [standard mean difference (SMD): 0.92, 95% CI: (0.58, 1.27), p < 0.000 01], laminin (LN) [SMD: 0.64, 95% CI: (0.38, 0.90), p < 0.000 01], and procollagen type III [SMD: 0.48, 95% CI: (0.28, 0.67), p < 0.000 01], while increasing the total effective rate by 24% [risk ratio: 1.24, 95% CI: (1.15, 1.32), p < 0.000 01]. There were no severe adverse events during treatment. Conclusions: SF was a potential adjuvant for antiviral therapy in restoring liver function. However, the poor quality of the included randomized controlled trials limited the recommendations. More long-term, randomized, and double-blind studies should be performed to assess the efficacy and safety of combination therapy.
