Objective Metabolic syndrome ( MS), a disorder involving multiple metabolic abnormalities such obesity,hypertension, diabetes or abnormal glucose tolerance and dyslipidemia, has been observed in many patients receiving coronary artery bypass procedures. In this study we try to examine the perioperative effects of metabolic syndrome on the off-pump coronary artery bypass (OPCABG). Methods A prospective study was conducted in 1060 consecutive OPCABG patients who were admited to Beijing Anzhen Hospital from July 2009 to March 2010. The patients were grouped as MS group and non-MS group according to the diagnostic criteria for Chinese metabolic syndrome. The outcomes such as mortality, atrial fibrillation,stroke, staying in ICU for more than three days, use of IABP, ECMO, dialysis, multiple organ dysfunction score ( MOOS) ,postoperative score for cardiac surgery (PSCS), PaO2/FiO2 , heart rate x central venous pressure/mean artery pressure(pressure-adjusted heart rate, PAHR) ,renal and liver function, platelets, and the dosage of vasoactive agents were analyzed and compared between the two groups by x2 test or t test. Results Three hundred and eighty-nine cases were diagnosed with MS among 1060 cases with OPCABG. In the MS group, 17 cases stayed in ICU for more than 3 days, 2 cases died, 76 had atrial fibrillation, 3 had stroke, 18 cases were treated with intra-aortic balloon counterpulsation (IABP). In the non-MS group, 47 cases stayed in ICU for more than 3 days, 12 cases died, 148 had atrial fibrillation, 3 had stroke, 48 cases were treated withIABP, 3 cases received ECMO and 4 cases received dialysis. No significant difference between MS group and non-MS group was identified in the aspects of mortality, atrial fibrillation, stroke, duration of more than three days in ICU, the use of IABP,ECMO, dialysis after OPACBG based on the x2 test(P＞0.05). However, on the operative days, the MODS and PSCS in MS group were significantly higher than that in non-MS group (P ＜ 0.05). MODS 2. 57 ± 1. 62 in MS group vs. 2. 15 ± 1.65 in non-MS group, PSCS 4.27 ±2.15 in MS group vs. 3.92 ±2.29 in non-MS group. PaO2/FiO2 in MS group was significantly lower than that in non-MS group (249.23 ± 110.99 vs. 283. 33 ± 114. 35), P ＜ 0. 01. PAHR in MS group was significantly higher than that in non-MS group (9.98 ±3.54 vs. 9.23 ±3. 88), P ＜0.05. On the first postoperative days, the MODS in MS group was also significantly higher than that in non-MS group (3.05 ±1.64 vs. 2.82 ± 1.72), P＜0.05. PaO2/FiO2 in MS group was significantly lower than that in non-MS group (277.11 ±122.99 vs.318.47 ±143.84), P＜0.05. Conclusion MS was not a predictor for death, atrial fibrillation, stroke, duration of more than three days in 1CU, the use of IABP, ECMO, dialysis after OPACBG. However, MS had a temporary adverse effect on the respiratory and circulatory systems on the operative day and the first postoperative day after OPCABG.

AIM: To investigate the effect of antisense oligodeoxynucleotides (AS - ODN) on the intercellsular adhesion molecule- 1 (ICAM- 1 ) expression on endothelial cells in hypoxia/reoxygenation(H/R). METHODS: With cultured glomerular vascular endothelial cell in H/R, the positive percentage of ICAM - 1 expression was measured by flow cytometry before and after giving AS - ODN. RESULTS: The ICAM - 1 expression did not increase on glomerular vascular endothelial cell in 10 hours hypoxia compared to control group, it increased in 6 hours reoxygenation, and decreased by 40.6 % after giving AS- OND. CONCLUSION: AS - ODN may decrease the expression of ICAM- 1 on endothelial cells in H/R.

Objective:To investigate the expression of microRNA (miR)-938, its effect on cell proliferation and its regulatory mechanism in hepatocellular carcinoma (HCC).Methods:HCC and paracancerous tissues were collected from 40 patients with HCC who underwent surgical resection in the Second Affiliated Hospital of Nantong University from January 2015 to June 2019, including 25 males and 15 females, with an average age of 61.4 years. HepG2 cells in the miR-938 overexpression group were transfected with miR-938 mimics, and the negative control group was transfected with the negative control sequence. Cell proliferation was detected by kit, the expression of miR-938 and the succinate dehydrogenase complex subunit D (SDHD) was detected by fluorescence quantitative polymerase chain reaction, and SDHD protein expression was detected by Western blot. The target genes of miR-938 were verified by dual luciferase reporting.Results:The relative expression of miR-938 in HCC tissues was (0.060±0.002), which was higher than that in adjacent tissues (0.030±0.002), and the difference was statistically significant ( P<0.05). The mRNA relative expression of SDHD in HCC tissues was (0.028±0.002), lower than that in adjacent tissues (0.062±0.002), and the protein expression of SDHD in HCC tissues was (0.963±0.008), lower than that in adjacent tissues (1.083±0.037), with statistical significance (both P<0.05). The proliferation activity of miR-938 overexpression group was significantly higher than that of negative control group, and the difference was statistically significant ( P<0.05). MiR-938 significantly inhibited the luciferase activity of SDHD wild-type 3’-untranslated regions. In the overexpression miR-938 cells, SDHD mRNA and protein levels were significantly lower than those in the negative control group ( P<0.05). Conclusion:MiR-938 was highly expressed in HCC tissues. MiR-938 promoted the proliferation of HCC cells by inhibiting the expression of SDHD.

OBJECTIVE: To study the role of follicular helper T (Tfh) cells and galactose-deficient IgA1 (Gd-IgA1) in the pathogenesis of childhood Henoch-Schönlein purpura (HSP) and the correlation between them. METHODS: A total of 36 children with newly-diagnosed HSP were enrolled. They were divided into two groups: HSP nephritis (HSPN) group with 11 children and non-HSPN group with 25 children according to the presence or absence of HSPN. Another 15 children who underwent physical examination at the outpatient service were enrolled as the healthy control group. Flow cytometry was used to measure the proportion of Tfh cells (CD4CXCR5ICOS) in peripheral blood. ELISA was used to measure the levels of interleukin-21 (IL-21) and interleukin-6 (IL-6) in peripheral blood and the serum levels of IgA1 and Gd-IgA1. A Pearson correlation analysis was used to investigate the correlation of serum Gd-IgA1 concentration with Tfh cells and related factors expression in the children with HSP. RESULTS: Both the HSPN and non-HSPN groups had significantly higher proportion of Tfh cells and expression levels of IL-21 and IL-6 in peripheral blood than the healthy control group (P<0.05). The HSPN group had significant increases in the above indices compared with the non-HSPN group (P<0.05). Both the HSPN and non-HSPN groups had significantly higher serum levels of IgA1 and Gd-IgA1 than the healthy control group (P<0.05). The HSPN group had significantly higher serum levels of IgA1 and Gd-IgA1 than the non-HSPN group (P<0.05). In the children with HSP, serum Gd-IgA1 level was positively correlated with Tfh cells proportion and IL-21 and IL-6 levels (P<0.05). CONCLUSIONS Tfh cells and related cytokines and serum Gd-IgA1 are involved in the development of HSP/HSPN. Tfh cells may mediate the increased production of Gd-IgA1.
