OBJECTIVETo assess the association of single nucleotide polymorphisms (SNPs) of endotheline receptor gene with the severity of coronary heart disease (CHD).

METHODSA total of 553 CHD patients, including 324 patients with mult-vessel disease based on result of selected coronary angiography, and 553 age- and sex-frequency matched controls were selected. Clinical data were collected. Genotypes of rs501120, rs899997, rs1878406 and rs7173743 were determined with TaqMan-MGB probes.

RESULTSThe distribution of genotypes of the 4 SNPs showed no significant difference between the two groups. However, the frequency of A allele of rs501120 and T allele of rs1878406 were significantly higher in the CHD group compared with the control group (P< 0.05). For rs7173743 and rs899997, no significant difference was detected between the two groups. After adjusting for conventional risk factors by logistic regression analysis, the results suggested that the distribution of rs1878406 TT+TC genotype in severe multi-vessel disease group is significantly higher than that in the control group (OR=1.43, 95% CI: 1.05-2.07, P=0.033).

CONCLUSIONThe above results suggested that the rs1878406 polymorphism of endotheline receptor gene may serve as a genetic marker for severe multi-vessel disease in CHD among ethnic Han Chinese.

In previous study, the 150-ku oxygen-regulated protein(ORP150) was identified as a candidate glycoprotein related to hepatocellular carcinoma.In order to further validate the expression level of ORP150 in hepatocellular carcinoma, protein expression was determined by Western blot and cell immunochemistry, and messenger RNA(mRNA) expression was detected by quantitative real-time polymerase chain reaction.The effect of ORP150 on apoptosis and invasive potential of hepatocellular carcinoma cells was evaluated using the small interference RNA(siRNA) technique.Both the protein and mRNA expression levels of ORP150 were significantly upregulated in hepatocellular carcinoma cell lines compared with a non-tumor human liver cell line.After transfection with the specific siRNA of ORP150, significantly greater apoptosis of hepatocellular carcinoma cells was induced compared with untransfected cells.However, no significant effect on invasive potential was found.Overexpression of ORP150 was associated with hepatocellular carcinoma, and ORP150 might promote the proliferation of hepatocellular carcinoma cells by inhibiting apoptosis.ORP150 could be a potential therapeutic target for hepatocellular carcinoma.

Objective To discuss the effect of PI3K-AKT signaling pathway regulated by microRNA-155(miRNA-155)targeted protein tyrosine phosphatase non-receptor type 21(PTPN21)on the proliferation,migration and invasion of hepatocellular carcinoma(HCC)cells.Methods Lentivirus transfection was used to silence the expression of miRNA-155 in human Huh7 HCC cells,and real-time fluorescent quantitative polymerase chain reaction(RT-qPCR)was used to detect the silencing effect of miR-155.After obtaining stable cell lines,the cell lines were randomly divided into Blank group(normal Huh7 cells),shNC group(Huh7 cells+empty miR-155 vector),sh-miR-155(Huh7 cells+miR-155 silencing),sh-miR-155+Recilisib group(Huh7 cells+miR-155 silencing+PI3K-AKT agonist),shNC+Recilisib group(Huh7 cells+empty miR-155 vector+PI3K-AKT agonist).Dual luciferase assay was used to determine whether PTPN21 was the downstream of miR-155.The cell proliferation ability of cells in each group was detected by MTT assay.The apoptosis level of each group was tested by flow cytometry.The invasion and migration ability of cells was assessed by Transwell assay.Western blot analysis was used to observe the differences in protein expression of PTPN21,PI3K,P-PI3K,AKT,P-AKT,and apoptosis-related proteins including BAX,BCL-2 and caspase-3 in all groups.Results The expression level of miR-155 in sh-miR-155 group was lower than that in Blank group and shNC group(P＜0.000 1),and the difference in miR-155 expression level between Blank group and shNC group was not statistically significant(P＞0.05).MTT results showed that A values of Huh7 cells at 2,3,4 and 5 day in sh-miR-155 group were lower than those in Blank group and shNC group(P＜0.000 1),while these differences between Blank group and shNC group were not statistically significant(P＞0.05).In sh-miR-155 group the A values at 2,3,4 and 5 day were lower than those in sh-miR-155+Recilisib group and shNC+Recilisib group(P=0.0052 and P＜0.0001,respectively),while the A values at 2,3,4 and 5 day in sh-miR-155+Recilisib were lower than those in shNC+Recilisib group(P＜0.000 1).There was no significant differences in cell migration and number of invasion cells between the Blank group and shNC group(P＞0.05).After activation of PI3K-AKT signaling pathway,the migration and invasion capacity of HCC cells in the shNC+Recilisib group were significantly enhanced when compared with the Blank group(P＜0.000 1).In contrast,the number of migrated and invaded Huh7 cells after miR-155 silencing was significantly lower than that in the Blank group and shNC group(P＜0.000 1)and this phenomenon became reversed by PI3K agonist.Compared with the sh-miR-155 group,in the sh-miR-155+Recilisib group the migration and invasion ability of HCC cells was enhanced(P=0.000 2).Lentiviral transfection of Huh7 human HCC cells to silence miR-155 and downregulate miR-155 inhibiting PTPN21 regulation of the PI3K-AKT signaling pathway,thus inhibiting the invasion,migration and proliferation ability of HCC cells and promoting the apoptosis of HCC cells.Conclusion miR-155 inhibits the migration,invasion and proliferation of HCC cells through targeting PTPN21 regulation of PI3K-AKT signaling pathway.The miR-155 may be a potential therapeutic target for HCC in the future.(J Intervent Radiol,2024,32:44-51)

Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

ObjectiveTo describe the incidence and distribution characteristics of congenital heart disease in newborns， and to analyze the trend of the notification rate from 2009 to 2018 in Chongming District， Shanghai. MethodsBased on the shanghai birth defects surveillance system， newborns delivered in all medical institutions in Chongming District from 2009 to 2018 were examined for congenital heart disease at birth and followed up to 42 days. The notification rate and trends of various congenital heart diseases were described. ResultsThere were 548 cases of neonatal congenital heart disease in Chongming District from 2009 to 2018， and the notification rate was 20.11‰ （95%CI： 18.47‰-21.85‰）， with statistically significant differences between years during the study period （Z=10.616， P<0.001）. The four most common types of congenital heart disease were patent ductus arteriosus （313， 11.49%）， patent foramen ovale （312， 11.45%）， atrial septal defect （88， 3.64%） and ventricular septal defect （73， 2.68%）. Majority of the congenital heart disease cases were patent ductus arteriosus and patent foramen ovale that could be further closed during growth and development. Isolated patent ductus arteriosus and isolated patent foramen ovale accounted for 18.61% and 23.18% respectively of the total cases. ConclusionThe notification rate of congenital heart disease in Chongming District shows a trend of fluctuating decline followed by an increase. Community follow-up and outcome tracking should be strengthened for children with congenital heart disease， especially those with patent ductus arteriosus or patent foramen ovale.
