Objective To investigate the effects of Licorice chalcone A(LCA)on proliferation,migration,invasion and antioxidant capacity of human glioma U87 cells and its mechanism.Methods Glioma U87 cells cultured in vitro were divided into 4 groups,blank control group(conventional culture)and experimental-L,-M,-H groups(5,10,20 μmol·L-1 LC A).Cell proliferation capacity was detected by cell counting kit-8,cell clonogenesis ability was detected by clonogenesis assay,cell migration ability was detected by scratch assay,and cell invasion ability was detected by Transwell assay.Colorimetric assay was used to detect total glutathione(T-GSH),malondialdehyde(MDA)and superoxide dismutase(SOD),and Western blotting was used to detect the protein expression levels of phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt).Results The cell proliferation activities of blank control group and experimental-L,-M,-H groups were(90.20±2.17)％,(79.06±1.57)％,(66.13±2.11)％and(49.52±1.82)％;cell clone formation rates were(76.83±2.30)％,(42.33±2.09)％,(17.71±1.84)％and(12.12±1.97)％;12 h cell mobility rates were(34.92±2.24)％,(27.90±1.89)％,(18.76±1.14)％and(14.87±0.82)％;24 h cell mobility rates were(50.37±2.61)％,(39.43±2.56)％,(21.11±2.33)％and(18.32±2.39)％;the number of perforated cells were 120.39±4.16,79.95±3.83,45.67±3.55 and 18.14±2.85;T-GSH levels were(71.43±2.39),(58.51±2.91),(49.43±2.78)and(35.44±2.76)μmol·L-1;MDA levels were(4.14±0.91),(7.23±1.75),(9.20±1.56)and(11.37±1.90)nmol·mL-1;SOD levels were(41.44±2.10),(35.43±2.91),(28.56±2.32)and(20.62±2.05)U·mg-1;the relative expression levels of p-Akt were 1.27±0.03,1.06±0.02,0.89±0.01 and 0.60±0.02,respectively.The above indexes were statistically significant between experimental-L,-M,-H groups and blank control group(all P＜0.01).Conclusion LCA can inhibit the proliferation,migration,invasion and induce oxidative damage of glioma U87 cells,and its mechanism may be related to the down-regulation of p-Akt protein expression in PI3K/Akt signaling pathway.

Objective　To observe the molluscicidal effect of a new molluscicide, 10% chlorosalicylicamide (LDS), against the intermediate hosts of Schistosoma mansoni - Biomphalaria glabrata and Biomphalaria straminea, thus to provide the experimental foundation for the field application of this molluscicide. Methods　The 10% LDS was formulated into the series of standard solutions with effective concentrations of 0.400 0, 0.200 0, 0.100 0, 0.050 0, 0.025 0 mg/L and 0.012 5 mg/L, respectively. B. glabrata and B. straminea were separately immersed in these solutions in the laboratory. The deaths of the above snails were observed after immersing into the solutions for 24, 48, and 72 h, and the mortalities of each group were computed, as well as the median lethal concentration LC50 (s) and relative toxicity indexes were calculated. Meanwhile, 50% wettable power of niclosamide ethanolamine salt (WPN) was set as the drug group, and dechlorinated water as the blank control group. Results　 The effective concentration of LDS at or above 0.100 0 mg/L, or WPN at or above 0.200 0 mg/L resulted in a 100% mortality rate for B. glabrata and B. straminea after immersing 24, 48, and 72 h. The LC50 (s) at 24, 48, and 72 hours for Biomphalaria glabrata immersed in the LDS series concentration solution was 0.047 95, 0.046 52, and 0.037 10 mg/L, respectively; while the LC50 (s) of B. glabrata in WPN serial solutions was 0.063 48, 0.057 05, 0.057 05 mg/L for 24, 48 and 72 h, respectively. For Biomphalaria straminea, the LC50 (s) at 24, 48, and 72 hours in the LDS solution was 0.012 35, 0.013 99, and 0.008 40 mg/L, respectively; and for the WPN solution, it was 0.058 95, 0.025 71, and 0.0237 5 mg/L. Using WPN as the standard drug which had higher value of LC50, and the relative toxicity index of WPN was set to 1.00, the relative toxicity indexes of LDS against B. glabrata were 1.32, 1.23 and 1.54 for 24, 48 h and 72 h, respectively, while for B. straminea, it was 4.77, 1.84, and 2.83. After 24, 48, and 72 hours of immersion in LDS, the number of surviving B. glabrata was significantly higher than that of B. straminea, with a statistical significance (χ2=8.044, 5.263, 4.658, P<0.05, respectively). Conclusions　Compared to the traditional molluscicide WPN, 10% LDS shows a superior molluscicidal effect on B. glabrata and B. straminea, especially demonstrating heightened sensitivity and efficacy on B. straminea, suggesting its potential as a substitute agent for snail control.

Objective To investigate the effect of aspirin on oxygen glucose deprivation/reoxygen-ation(OGD/R)-induced injury in mouse hippocampal neuron HT22 cells by regulating ferropto-sis.Methods HT22 cells were randomly divided into control group,model group,low-,medium-and high-dose groups(n=3).Cellular OGD/R injury model was established in the other 4 groups except the control group.Aspirin of 100,200 and 400 μg/ml was used to treat the cells from the above 3 treatment groups,respectively.Cell viability was detected by CCK-8 assay.The contents of TNF-α,IL-1β and IL-6 were detected by ELISA.The contents of SOD,catalase,glutathione,reac-tive oxygen species(ROS),lactate dehydrogenase(LDH),Fe2+and MDA were detected by the corresponding reagent kits.Western blot analysis was performed to determine the expression of solute carrier family 7 members 11(SLC7A11),glutathione peroxidase 4(GPX4)and Acyl-CoA synthase long chain member 4(ACSL4).Results The model group had significantly lower cell vi-ability than the control group(0.49±0.07 vs 1.00±0.12,P＜0.01),but the viability of the low-,medium-and high-dose groups were higher than that of the model group(0.72±0.10 vs 0.49±0.07,P＜0.05;0.87±0.10 vs 0.49±0.07,P＜0.01;0.93±0.07 vs 0.49±0.07,P＜0.01).Compared with the control group,the contents of TNF-α,IL-1β,IL-6,ROS,LDH,Fe2 and MDA and the protein expression of ACSL4 were significantly increased,while the contents of SOD,catalase,glutathione and protein levels of SLC7A11 and GPX4 were obviously decreased in the model group(P＜0.01).Compared with model group,aspirin treatment reversed all above indicators no matter its doses(P＜0.05,P＜0.01).Conclusion Aspirin alleviates OGD/R-induced neuronal in-jury through regulating ferroptosis in mouse neuron HT22 cells in a dose-dependent manner.

Objective To investigate the serum S100 calcium-binding protein A4(S100A4)and fibronectin type Ⅲ domain-containing 5(FNDC5)levels in patients with gestational diabetes mellitus(GDM)and their relationship with pregnancy outcomes.Methods From June 2020 to June 2022,a total of 126 patients with GDM in the hospital were included into GDM group,and 126 healthy pregnant women who underwent prena-tal check ups during the same period were selected as the control group.According to the pregnancy outcome of GDM patients,they were grouped into a good pregnancy outcome group(76 cases)and a adverse pregnancy outcome group(50 cases).The levels of S100A4 and FNDC5 were detected by enzyme linked immunosorbent assay(ELISA).Multivariate Logistic regression analysis was applied to analyze the influencing factors of pregnancy outcome in GDM pregnant women.Receiver operating characteristic(ROC)curve was applied to e-valuate the value of serum S100A4 and FNDC5 in predicting adverse pregnancy outcomes in GDM pregnant women.Spearman correlation analysis was applied to analyze the correlation between serum S100A4,FNDC5 and adverse pregnancy outcomes.Results The serum S100A4 level in GDM group was higher than that in control group(P<0.05),while the serum FNDC5 level was lower than that in control group(P<0.05).The serum S100A4 level in the good pregnancy outcome group was lower than that in the adverse pregnancy out-come group(P<0.05),while the serum FNDC5 level was higher than that in the adverse pregnancy outcome group(P<0.05).Spearman correlation analysis showed that serum S100A4 level in GDM patients was posi-tively correlated with adverse pregnancy outcomes(P<0.05),while FNDC5 level was negatively correlated with adverse pregnancy outcomes(P<0.05).Logistic regression analysis showed that serum S100A4,fasting blood glucose,and HOMA-IR were risk factors for adverse pregnancy outcomes in GDM patients(P<0.05),and FNDC5 was a protective factor for adverse pregnancy outcomes in GDM patients(P<0.05).The area un-der the curve of the combination of serum S100A4 and FNDC5 in predicting pregnancy outcomes in GDM was greater than that of S100A4 alone(Z=2.045,P=0.041)and FNDC5 alone(Z=2.010,P=0.044).Conclu-sion The level of S100A4 in the serum of GDM patients is high,and the level of FNDC5 is low.Both have certain reference value for evaluating the pregnancy outcome of GDM pregnant women.

Objective To explore the correlation between serum microRNA-29a-3p(miR-29a-3p),throm-bospondin 2(THBS2)and cardiopulmonary function in children with chronic pulmonary heart disease.Meth-ods A total of 136 children with chronic pulmonary heart disease treated in Shijiazhuang Hospital of Tradi-tional Chinese Medicine from July 2019 to September 2023 were selected as the study subjects.Based on their clinical signs,cardiopulmonary function,and symptoms,they were divided into a compensated group(74 ca-ses)and a decompensated group(62 cases).Real-time fluorescence quantitative PCR(RT-qPCR)method was applied to detect serum miR-29a-3p level,and enzyme-linked immunosorbent assay(ELISA)was applied to detect serum THBS2 level.Moreover,ultrasound diagnostic equipment was applied to detect cardiac function indicators such as left ventricular ejection fraction(LVEF)and cardiac output(CO).Creatine kinase isoenzyme(CK-MB)and troponin(cTnl)were detected by electroluminescence analysis.Pulmonary function indicators were detected by pulmonary artery systolic pressure(PASP),mean pulmonary artery pressure(MPAP)and pulmonary artery diastolic pressure(PADP).Pearson correlation was used to analyze the corre-lation between serum miR-29a-3p and THBS2 levels and cardiopulmonary function indexes in children with chronic pulmonary heart disease,and multivariate Logistic regression analysis was used to screen the influen-cing factors of the disease in children with chronic pulmonary heart disease.Receiver operating characteristic(ROC)curve was drawn to analyze the evaluation value of serum miR-29a-3p and THBS2 levels in children with chronic pulmonary heart disease.Results The THBS2,CK-MB,cTnI,PASP,MPAP,and PADP in the decompensated group were higher than those in the compensated group(P＜0.05),while miR-29a-3p,LVEF,and CO were lower than those in the compensated group(P＜0.05).Serum miR-29a-3p in children with chro-nic pulmonary heart disease was positively correlated with LVEF and CO(P＜0.05),but negatively correla-ted with CK-MB,cTnI,PASP,MPAP,and PADP(P＜0.05).THBS2 was negatively correlated with LVEF and CO(P＜0.05),but positively correlated with CK-MB,cTnI,PASP,MPAP,and PADP(P＜0.05).MiR-29a-3p was a protective factor for exacerbation of chronic pulmonary heart disease in children(P＜0.05),while THBS2 was an independent risk factor for exacerbation of chronic pulmonary heart disease in children(P＜0.05).ROC curve analysis results showed that the area under the curve(AUC)of serum miR-29a-3p and THBS2 levels alone and in combination for evaluating the severity of chronic pulmonary heart disease in children were 0.827,0.817 and 0.915,respectively.Conclusion Serum miR-29a-3p and THBS2 levels are both factors affecting the disease of children with chronic pulmonary heart disease,and are closely related to the disease and cardiopulmonary function of children with chronic pulmonary heart disease.
