OBJECTIVETo compare the long-term survival and postoperative complications of distal gastric cancer patients between Billroth I((BI() and Billroth II((BII() reconstruction.

METHODSClinicopathological data of 992 patients with distal gastric cancer who underwent D2 curative gastrectomy in our department from May 2008 to April 2015 were recorded, including 207 patients of BI( reconstruction and 785 of BII( reconstruction, were retrospectively analyzed. Patients presenting a previous history of cancer, gastric resection or cytotoxic chemotherapy, and those presenting liver or intraperitoneal tumor dissemination or unresectable infiltration into contiguous organs were excluded. Patients in BI( and BII( group were selected using gmatch methods based on age (±10 years), gender, tumor size (±1 cm), differentiated degree and depth of invasion in order to reduce the selection bias of clinicopathological characteristics. The final number of patients matched was 191 respectively.

RESULTSCompared with BII( group, the BI( group had a significantly shorter operation time (181.7 min vs. 220.7 min, P=0.000) and a shorter postoperative hospitalization stay (7.6 days vs. 8.1 days, P=0.046). The postoperative complications including anastomotic leakage, wound dehiscence, wound infection, intraperitoneal hemorrhage, intestinal obstruction, duodenal stump fistula, pulmonary infection and fever had no significant difference(P>0.05). Three-year survival between two groups was comparable (82.9% vs. 78.7%, P=0.379).

CONCLUSIONSCompared with BII(, BI( reconstruction is more suitable for patients with distal gastric cancer.

OBJECTIVETo investigate the relationship of ABO blood group with the clinicopathological characteristics in patients with gastric cancer and to assess whether the ABO blood group was associated with prognosis.

METHODClinicopathological and follow-up data of 2838 patients with gastric cancer who underwent radical gastrectomy in our department from June 2008 to October 2013 were analyzed retrospectively. The distribution of ABO blood group under different clinicopathological characteristics and the overall 5-year survival of ABO blood group were compared.

RESULTSThere were no significant differences in clinicopathological characteristics among patients with different ABO blood groups (all P>0.05). The 5-year overall survival(OS) rates were 57.3% for patients with blood type A, 54.7% for type B, 57.4% for type O, and 53.5% for type AB. Though there was no significance difference of survival among ABO blood groups(P=0.722), while the subgroup analysis indicated that stage III( patients of blood group Non-AB had a poorer OS compared to those of blood group AB(25.2% vs. 44.7%, P=0.014); smoking patients of blood group Non-AB had a poorer OS compared to those of blood group AB(53.4% vs. 74.9%, P=0.044).

CONCLUSIONNeither clinicopathological characteristics nor overall survival are associated with the ABO blood group, however, stage III( and smoking patients of blood group Non-AB have a poorer OS compared to those of blood group AB.

Aim To study the inhibitory effect of ginsenoside Rgl on neuronal ferroptosis after ischemic stroke and its mechanism. Methods A model of oxygen glucose deprivation/reoxygenation (OGD/R) was established in HT22 cells, and the effect of Rgl on the viability of HT22 cells after OGD/R injury was detected by CCK-8. The effect of Rgl on ferroptosis in HT22 cells after OGD/R injury was detected by the test of ferroptosis markers GSH/GSSG, SOD, MDA, and Fe

Objective　Diabetic cardiomyopathy (DCM) is one of the complications of diabetes, which is closely related to the change of miRNA. In this study, we observed the characteristic expression of miR-26b in the tissues of the C57BL/6J mouse and in the heart, adipose tissue and liver of the ob/ob mouse, and investigated the effect of high glucose (Glu) on the expression of miR-26b in H9C2 cardiomyocytes.　Methods　Using RT-PCR, we measured the levels of miR-26b in the heart, adipose tissue, liver and other tissues of C57BL/6J and ob/ob mice. H9C2 cardiomyocytes were treated with Glu at 5.5, 15, 25 and 35 mmol/L for 0, 24, 48, 72, 96 and 120 hours, followed by detection of the proliferation of cardiomyocytes by CCK-8 and determination of thelevels miR-26b.　Results　The expression of miR-26b was the highest in the heart of the C57BL/6J mice, significantly higher than in the cardiac and white adipose tissues of the ob/ob mice (P < 0.05). The proliferation of cardiomyocytes was markedly increased in the 15, 25 and 35 mmol/L Glu groups at 24, 48, 72, 96 and 120 hours as compared with that in the 5.5 mmol/L Glu group (P < 0.05), higher in the 25 than in the 15 mmol/L Glu group at 24 hours (0.74±0.02 vs 0.72±0.01, P<0.05), but lower in the 35 than in the 15 mmol/L Glu group at 48 hours (0.92±0.01 vs 0.94±0.01, P<0.05), in the 25 and 35 mmol/L Glu groups at 96 hours (P < 0.05), in the 35 mmol/L Glu group at 120 hours (1.12±0.02 vs 1.19±0.05, P<0.05), in the 35 than in the 25 mmol/L Glu group at 24 and 48 hours (P<0.05). The expression of miR-26b in the H9C2 cardiomyocytes was significantly down-regulated in the 25 and 35 mmol/L Glu groups in comparison with that in the 5.5 mmol/L Glu group (P<0.05), remarkably lower in the 25 mmol/L Glu group at 96 and 120 hours than at 0 hour (P<0.05).　Conclusion　High glucose can down-regulate the expression of miR-26b in H9C2 cardiomyocytes, which suggests that miR-26b may participate in the pathogenesis of DCM.

Objective To investigate the relationship between the levels of plasma adrenaline and norepinephrine and gene polymorphism of β1 adrenergic receptor G1165C in children with enterovirus 71 (EV71) infection in hand foot and mouth disease (HFMD). Methods The polymerase chain reaction (PCR) was used to detect the expression of gene polymorphism of β1 adrenergic receptor G1165C in vitro. The levels of plasma adrenaline and norepinephrine were measured by enzyme-linked immunosorbent assay (ELISA). Results The plasma norepinephrine level of severe group was significantly higher than the mild group in children with EV71 infection in HFMD (P < 0.05); however, the levels of plasma adrenaline in two groups had no statistical differences (P > 0.05); There was no significant difference in the distribution of β1 adrenergic receptor G1165C genotype and allele between EV71 infection group and healthy control group (P > 0.05). Further analysis of EV71 infection group by dividing it into mild and severe groups showed that there was no significant difference in the distribution of genotype and allele between these two groups as well (P > 0.05). There was no significant difference in the levels of epinephrine and norepinephrine in different genotypes of EV71 infection group (P > 0.05), and in the levels of plasma epinephrine and norepinephrine in the mild and severe groups (P > 0.05). Conclusions As the disease gets worse, the plasma norepinephrine level has a rising trend in children with EV71 infection in HFMD, which is an important indicator to evaluate the progress of the disease. However, the gene polymorphism of β1 adrenergic receptor G1165C have no significant correlation, not only with the susceptibility and severity of EV71 infection in hand, foot and mouth disease, but also with the levels of catecholamine.
