Objective To investigate the effects and the possible mechanism of insulin like growth factor-1 ( IGF1 ) on proliferation and migration of human umbilical vein endothelial cells ( HUVEC) in high glucose. Methods Cultured HUVEC were divided into 5 groups( control group, high glucose group, hypertonic group, high glucose+IGF 1 group, high glucose+IGF1+ AZD5363 group) . The proliferation was detected by methyl thiazolyl tetrazolium ( MTT) , the migration was detected by transwellchamber. The mRNA expressions of serine/threonine kinase( Akt) and FoxO1 were detected by real-time PCR. The protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were detec-ted by immunohistochemisty. Results Compared with the control group, the rate of cell survival in high glucose group decreased significantly(P<0. 05), the transitional was decreased significantly(P<0. 05), the mRNA ex-pression of FoxO1 was increased significantly( P<0. 05 ) , the protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were increased. Compared with high glucose group, the cell survival rate and migration rate in high glucose+IGF1 group were increased significantly, the mRNA expression of FoxO1 was decreased significantly(P<0. 05), the protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were decreased. Compared with high glucose group, the cell survival rate and migration rate in high glucose+IGF1+AZD5363 group had no significant difference, the mR-NA expression of FoxO1 was decreased significantly ( P<0. 05 ) , the protein expressions of FoxO1/p-FoxO1 had no significant difference. The mRNA expression of Akt in five groups had no significant difference. Conclusion IGF1 can improve the proliferation and migration of endothelial cell in high glucose. It shows that IGF1 acts through Akt to promote FoxO1 phosphorylation.

Objective To investigate the effect of early goal lactate clearance rate therapy in patients with severe sepsis or septic shock.Methods Articles were retrieved from PubMed,Embase,Cochrane Library,Wanfang and CNKI before March 5,2016.Inclusion criteria included the subjects concerning patients with severe sepsis or septic shock reported as randomized controlled trial (RCT),which endpoints were the mortality,the length of ICU stay and hospital stay.RevMan 5.3 software was used for Meta analysis.Results There were 5 RCTs meeting inclusive criteria including 860 patients.It was shown by Meta analysis that early goal lactate clearance rate therapy was associated with decrease in the 28-day mortality(RR =0.73,95％ CI:0.60-0.88,P ＜ 0.01),shorten the length of ICU stay (WMD =-2.41,95％ CI:-4.68--0.14,P ＜ 0.05),but not associated with decrease of the length of hospital stay(WMD =-0.13,95 ％ CI:-4.58-4.31,P =0.95).Conclusion Early goal lactate clearance rate therapy was associated with significant improvement in 28-day mortality and the length of ICU stay but not with the length of hospital stay in patients with severe sepsis or septic shock.

Objective To investigate the correlation of the single nucleotide polymorphism (SNP) of PON1 (Paraoxonase-1) gene rs854572 to the occurrence of clopidogrel resistance (CR). Methods A case-control method was employed in present study. A total of 850 hospitalized patients with coronary artery diseases (CAD) in General Hospital of Shenyang Command were enrolled. The residual platelet aggregation rate (RPA) induced by 20μmol/L of adenosine diphosphate (ADP) was detected by optical nephelometry, and RPA≥70% was defined as CR. Accordingly, all the enrolled 850 patients were then divided into CR group (n=215) and non-CR (NCR) group (n=635). Polymerase chain reaction (PCR) and pyrophosphate sequencing were executed to determine the genotypes and the allele frequencies of PON1 gene rs854572. Results The genotype frequencies in rs854572 of PON1 gene conformed well to the Hardy-Weinberg equilibrium in both CR group and NCR group. Three frequencies of genotype CC, CG and GG were 23.7%, 49.3%, 27.0% in CR group, and 24.1%, 50.2%, 25.7% in NCR groups, respectively. No significant difference in genotype and allele frequency existed between CR group and NCR group (P=0.93 and 0.76, respectively). Logistic regression analysis revealed that no correlation between rs854572 SNP of PON1 gene and the formation of CR in patients with CAD after adjustment of correspondent factors including age, gender, body mess index, smoking, hypertension, diabetes mellitus and hyperlipidemia. Conclusions It is considered that no correlation exists between PON1 gene rs854572 polymorphism and clopidogrel resistance in patients with coronary heart disease.

BACKGROUND:Studies have confirmed that nicotine affects the activity of osteoblasts, osteoclasts, fibroblasts and erythrocytes.
OBJECTIVE:To study the nicotine effects on osseointegration and the expression of osteoprotegerin and bone morphogenetic protein 2 after implantation of dental implants with surface treatment by sandblasting or acid etching.
METHODS:Twenty-four Sprague-Dawley rats were randomly assigned to two groups and received daily injections for 2 weeks as folows: Nicotine 2 mg/kg twice for experimental group, saline solution for control group. Then the titanium implants with surface sandblasting or acid etching were implanted into the tibiae folowed by continuous nicotine or normal saline injection. At weeks 2 and 4 after implantation, the implants and surrounding bone tissue were prepared for CT, X-ray and hematoxylin-eosin staining examinations to evaluate bone healing and expression levels of bone-related genes were measured by quantitative RT-PCR.
RESULTS AND CONCLUSION: Compared with the control groups, the degree of osseointegration and the expression of osteoprotegerin and bone morphogenetic protein 2 in the experimental groups were decreased significantly (P < 0.05), except that the expression of bone morphogenetic protein 2 in the experimental group with acid etching was not significantly reduced. In addition, the expression of bone morphogenetic protein 2 in the experimental group with acid etching was higher than that in the experimental group with sandblasting at 2 weeks after implantation (P < 0.05). The X-ray and CT show that the quantities of new generation bone and the degree of bone mineralization of the sandblasting group were significant lower than those of the acid etching group under the intervention of nicotine. Hematoxylin-eosin staining showed that the activity and quantity of osteoblasts around the implants down-regulated significantly, but acid etching-treated implants showed better outcomes than sandblasting-treated implants.

Objective To investigate the effects of high frequency oscillatory ventilation (HFOV)combined with inhaled nitric oxide(iNO) on neonates with severe meconium aspiration syndrome(MAS).Methods Sixty newborn infants with severe MAS admitted to the neonatal intensive care unit of Shenzhen Children's Hospital from Oct 2008 to May 2011 were included for this study.All of them needed mechanical ventilation after birth and oxygenation index (OI) ＞ 30.According to the different ventilation modes,they were randomly divided into conventional mechanical ventilation (CMV) group,HFOV group and HFOV combined with iNO (HFOV + iNO) group,each group had twenty neonates.OI and the rate of air leak and pulmonary hypertension in each group were compared.Results Ventilation after 24 h,OI of HFOV group and HFOV + iNO group were significantly decreased as compared with CMV group (19.0 ± 4.5 vs 11.0 ± 5.3 vs 25.0 ± 7.1,P ＜ 0.05).In HFOV + iNO group,the obvious decline of OI(from 36.0 ± 7.4 to 24.0 ± 5.2) were observed at four hours after treatment.The rate of air leak in HFOV and HFOV + iNO groups was both zero as compared with CMV (5/20,25％).The rate of pulmonary hypertension in HFOV + iNO group was zero and the HFOV group was 30％ (6/20),the CMV group was 40％ (8/20).Conclusion HFOV combined with iNO was preferred treatment for neonates with severe MAS,and they have synergistic effect.

Objective: To investigate the epidemiological characteristics of hand, foot, and-mouth disease (HFMD) among children under 6 years in Wuxing District, Huzhou City from 2013 to 2021, so as to provide insights into HFMC control among children. Methods : The surveillance on HFMD and enterovirus 71 (EV71) vaccination among children under 6 years in Wuxing District, Huzhou City from 2013 to 2021 were captured from China Disease Prevention and Control Information System, and the temporal, human and spatial distributions of HFMD cases and pathogenic detection results were descriptively analyzed. Results : A total of 14 272 HFMD cases under 6 years were reported in Wuxing District from 2013 to 2021, with an average annual incidence rate of 465.75/104. There were 8 313 male children with HFMD (522.39/104 incidence) and 5 959 female children with HFMD (404.55/104 incidence), and higher incidence of HFMD was seen among male children than among female children (χ2=239.228, P<0.001). Most HFMD cases were found among children at ages of 1 to 3 years (10 006 cases, 70.11%), and the incidence of HFMD peaked during the period between May and July and between October and December each year. High incidence of HFMD was seen in Zhili Township (741.50/104), Yangjiabu Street (546.99/104) and Balidian Township (438.68/104). There were 717 laboratory-confirmed HFMD cases (5.02%), including 106 EV71-positive cases (14.78%) and 177 CoxA16-positive cases (24.69%). A total of 56 288 doses of EV71 vaccines were administered in Wuxing District from 2017 to 2021, with an annual average full-dose vaccination rate of 14.87%. The detection of EV71 infection was significantly lower after EV71 vaccination than before vaccination (4.49% vs. 24.93%; χ2=62.932, P<0.001). Conclusions The incidence of HFMD peaks in summer and winter among children under 6 years in Wuxing District, which predominantly occurs among children at ages of 1 to 3 years. The incidence of HFMD is high in Zhili Township, Yangjiabu Street and Balidian Township, and the number of EV71-positive cases significantly reduces after EV71 vaccination than before vaccination.

he blood supply of corpus callosum is rich, its function is complex, and the incidence of infarction is low. The risk factors and etiology for callosal infarction do not have any difference with the infarction in other parts of the brain. The clinical manifestations of the disease are complex and diverse. The two classical clinical manifestations are callosal disconnection syndrome and frontal-type gait disorder, but hemiplegia, monoplegia, apraxia, and mental retardation are common in clinical practice. The positive rate of CT scan is lower. MRI has higher sensitivity and specificity for callosal infarction. The diagnosis of callosal infarction is not difficult according to the history and imaging examination, however, it needs to be differentiated with other diseases that likely involve corpus callosum. Most of the patients with callosal infarction have good prognosis.
