Objective To observe the phosphorylation levels of extracellular signal-regulated kinase 5 (ERK5) in acute myocardial infarction (AMI) patients and the effects of ERK5 selective inhibitor XMD8-92 on human platelet activation in vitro,and to explore its mechanism.Methods Western blot was applied to detect the phosphorylation levels of ERK5,Akt473 and Akt308 in AMI patients (n =34) and stable angina patients (n =33,control).The effects of different concentration of XMD8-92 on human platelet aggregation induced by collagen was tested by aggregometer in vitro.The release of ATP was measured simultaneously by luciferase detection.The effects of XMD8-92 on integrin aIIbβ3 were detected by platelet spreading on immobilized fibrinogen and clot retraction.The effects of XMD8-92 on phosphorylation levels of Akt473,Akt308 PTEN370 and ERK5 were detected by Western blot.Results The levels of phosphor-Akt473,Akt308 and phosphor-ERK5 were significantly higher in AMI patients than that in control group (P＜0.05).ERK5 inhibitor XMD8-92 diminished collagen-induced platelet aggregation,ATP secretion,the average area of platelet spreading on immobilized fibrinogen and the clot retraction extent.The levels of phosphor-Akt (Ser-473/Thr-308) and phosphor-PTEN (Ser370) were significantly down-regulated in the presence of XMD8-92.Conclusions ERK5 plays a role in platelet activation in AMI process.It regulates platelet activation by regulating PTEN and Akt phosphorylation.Its specific inhibitor is hoped to be new antithrombotic drug.

OBJECTIVE:To observe clinical effects and safety of small dose of octreotide for preventing hyperamylasemia and acute pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP).METHODS:One hundred and twenty ERCP pa tients were selected from our hospital during Oct.2014-Jan.2015 and then divided in to observation group and control group in accordance with random number table,with 60 cases in each group.Both groups were given Diazepam tablet 10 mg+Meperidine hydrochloride tablet 100 mg+Phenobarbital scopolamine tablet 2 tablets 0.5 h before surgery for sedation and analgesia,and routine acid suppression and anti-infective therapy.Observation group was additionally given Octreotide acetate injection 0.1 mg hypodermically and then given Octreotide acetate injection 0.1 mg immediately after surgery,8 h after surgery.The levels of serum amylase and blood glucose were observed in 2 groups,and the occurrence of postoperative complication and ADR were recorded.RESULTS:Before operation,there was no statistical significance in the levels of serum amylase and blood glucose between 2 groups (P＞ 0.05).After operation,the level of serum amylase in control group was significantly higher than in observation group,with statistical significance (P＜0.05).There was no statistical significance in blood glucose level between 2 groups after operation (P＞0.05).The incidence of hyperamylasemia and ADR in observation group was significantly lower than in control group,with statistical significance (P＜0.05),and there was no statistical significance in the incidence of acute pancreatitis between 2 groups after operation (P＞0.05).CONCLUSIONS:Small dose of octreotide can effectively reduce the level of serum amylase and the incidence of hyperamylasemia after ERCP with good safety.

Objective To investigate the epidemiological characteristics of children infected by mycoplasma pneumoniae(MP)over the last five years in Kunming region.Methods Indirect immunofluorescence assay was used to detect blood MP-IgM of hospitalized patients from January 2003 to December 2007 in order to determine the age and gender distribution characteristics of MP infection and to investigate the epidemiological features of the five years' results.Results Infection incidences by MP in Kunming region over the last five years were 20.9%,14.3%,17.5%,15.7%and 19.5%,respectively.Statistical significance was found among the groups mentioned above(P＜0.01).The MP infection incidences in different age groups were 10.7%(～1 year old),20.5%(～3 years' old),21.5%(～6 years' old)and 21.7%(～14 years' old).MP infection incidences showed age and gender characteristics(P＜0.01).Infants showed lower NIP infection incidence and infection incidence was higher in female.The epidemiological investigation indicated that MP infection incidences varied from year to year(P＜0.01).The infection incidences of 2003 and 2007 by MP were higher than those of the other years.There were epidemiological differences in infection incidences by NIP over last five years(summer,autumn and winter).The MP infection incidences showed seasonal differences(P＜0.01).Conclusion Mycoplasma pneumoniae was the main local causative agent responsible for respiratory tract infection in children aged under one years' old in Kunming region.Over the last five years,there were two outbreaks in the local area,but with no seasonal regularity of epidemiology.

Objective To identify immunodominant B linear cell epitopes in capsid proteins VP1 to VP3 of Coxsackievirus A16 (CVA16) strain YY157.Methods The protean algorithms of bioinformatic software Lasergene were used to analyze antigenicity, hydrophilicity and surface probability of amino acid sequence of CVA16 capsid proteins VP1 to VP3.Multiple regions containing potential lineal B cell epitopes were predicted and their corresponding average indexes were calculated by BepiPred 1.0 Server.Corresponding peptides were synthesized and examined in peptide-enzyme-linked immunosorbent assay (ELISA) individually to check whether it reacted positively or negatively toward sera from children with confirmed CVA16 infection.Results Totally 21 possible B cell linear epitopes were predicted according to their relatively strong antigenicity, hydrophilicity and surface probability.The corresponding synthetic peptides reacted positively with sera of CVA16-infected children in a varying extent.Conclusion Immunodominant B cell linear epitopes of capsid proteins VP1 to VP3 of CVA16 strain YY157 are successfully predicted and confirmed.

In order to solve the problem of selection and in vivo delivery problem in siRNA treatment, hepatitis B virus (HBV) HBx gene which could be targeted by siRNA was studied. The siRNA expression plasmid which specific inhibits HBx expression was obtained by in vitro selection via a dual-luciferase plasmid including HBx-Fluc fusion protein expression domain. The selected siRNA expression plasmid was then encapsulated in PEG-modified cationic liposome, which was devoted into pharmacodynamic studies at both cellular and animal level. The results illustrated that the cationic liposome which encapsulated siRNA expression plasmid could effectively inhibit HBx gene expression both in vitro and in vivo.

Objective:To explore the behavior and influencing factors of mobile health (m-Health) information searching among patients with cancer, aiming to provide evidence for the provision of medical health information.Methods:A cross-sectional survey was conducted.A total of 535 patients with cancer were recruited from a cancer hospital in Zhejiang Province from September to December 2017.Measurement tools included the demographic information questionnaire, mobile health information search behavior questionnaire, mobile health information search environment questionnaire, cancer needs questionnaires-short form and ehealth literacy scale.SPSS 26.0 was used for descriptive statistical analysis, one-way analysis of variance, Pearson correlation analysis and multiple linear regression analysis.Results:The total score of mobile health information search behavior of cancer patients was (60.84±9.60), and 66.5% of participants reported that they "never" or "occasionally" searched health information via mobile.The total score of information needs was (80.99±27.86), electronic health literacy was (26.54±7.85), mobile health information search environment was (8.00±2.86). m-Health information search behavior was positively correlated with information needs ( r=0.251, P<0.01), ehealth literacy ( r=0.538, P<0.01), and m-Health information search environment ( r=0.267, P<0.01). The stepwise regression analysis revealed that the place of residence, working status, income level, ehealth literacy, mobile health information search environment and information needs were statistically significant associated with the m-Health information searching behavior among cancer patients, which accounted for 39.3% of the total variance ( F=12.151, P<0.01). Compared with patients living in the central cities, those living in the small and medium-sized cities( β=0.092, P=0.031) had higher score in m-Health information behavior.Compared with patients working on normal schedule, those took sick days ( β=0.156, P=0.017) and working fewer hours ( β=0.138, P=0.002) had higher score m-Health information behavior.Compared with patients with monthly income of 1 000-3 000 yuan ( β=-0.194, P=0.002), those with monthly income less than 1 000 yuan had higher score in m-Health information behavior.The ehealth literacy ( β=0.425, P=0.000), mobile health information search environment ( β=0.179, P=0.000) and information needs ( β=0.091, P=0.027) were positive influencing factors of m-Health information search behavior. Conclusion:Patients with cancer did not report high m-Health information search behavior.Place of residence, working status, income level, ehealth literacy, m-Health information search environment and information demand were the influencing factors of m-Health information search behavior among patients with cancer.
