It has become increasingly appreciated that newborn perceive and respond to pain.For immature preterm and illness term neonates,exposing to repeated and prolonged procedure pain can not only have short-term effects,such as behavioral and physiological variation or stress hormone and pain sensitization alternation,but also can cause long-term impacts including nervous system and pain system plasticity,chronic-pain-syndrome formation,endocrine modulating interference and behavioral,cognitive or emotional disorders.Here we provide a review about the effects of neonatal pain on health of short-term and long-term,and the mechanism of pain is also involved.

Objective To develop an analytical method by gas chromatograph-mass spectrometry(GC-MS) for the determination of organic chloride pesticides and polycyclic aromatic hydrocarbons in prophyra Methods The samples were extracted by an acetone-hexane(7∶3,V/V) mixture first,then were purified by C18 solid-phase extraction(SPE),and then were determined with GC-MS.Results The linear range was 0.01-5.0 ?g/ml,the limits of detection were 0.05-0.32 ng/g(dry weight) and 0.25-0.56 ng/g(dry weight)for organic chloride pesticides and polycyclic aromatic hydrocarbons respectively.The recovery rates and relative standard deviation for organic chloride pesticides were 74.27%-121.49% and 3.19 %-17.31% relatively;the recovery rates and relative standard deviation for polycyclic aromatic hydrocarbons were 65.10%-119.26% and 2.75%-14.11% relatively.Organic chloride pesticides were partly detected,but the detection rate of polycyclic aromatic hydrocarbons was higher.Fifteen polycyclic aromatic hydrocarbons were detected in all samples but dibenz(a,h)-anthracene.Conclusion This method is sensitive,accurate and applicable to the determination of organic chloride pesticides and polycyclic aromatic hydrocarbons in prophyra.

This study was aimed to observe the therapeutic effect and mechanism ofQi-Zhu Er-Zhu Er-Cao Tang(QZEZECT) in the treatment of chronic atrophic gastritis (CAG) precancerous lesion. A total of 56 clean grade healthy Wistar rats were randomly divided into 6 groups. In the negative control group (NC), model group,Wei-Fu-Chun(WFC) group,Ren-Zhu Jian-Wei Ke-Li(RZJWKL, RZ) group, there were 10 rats in each group. In the high-dose QZEZECT (QZ-H) group and low-dose QZEZECT (QZ-L) group, there were 8 rats in each group. CAG/PLGC model was established by MNNG in the model group, WFC group, RZ group, QZ-H group and QZ-L group. Intragastric administration of corresponding decoctions at the dose of 0.39 g·kg-1, 3.2 g·kg-1, 54.4 g·kg-1, 13.6 g·kg-1 were given to rats in the WFC, RZ, QZ-H and QZ-L groups once a day for 28 consecutive days, respectively. The same volume of normal saline was given to the NC group and the model group. Histomorphological changes of gastric mucous membrane in rats of each group were observed. Expressions of NF-κB/p65 and CyclinE protein were detected. The results showed that compared with the NC group, the degrees of infiltration and dysplasia and expressions of NF-κB/p65 and CyclinE significantly increased in the model group with statistical significance (P < 0.01). Compared with the model group, the expression of NF-κB/p65 and CyclinE in the WFC group reduced with statistical significance (P < 0.05). The expression of NF-κB/p65 and CyclinE in the RZ and QZ-L group obviously reduced with statistical significance (P < 0.01). The overall effective rates of WFC group, RZ group, QZ-H group and QZ-L group were 50%, 63.3%, 43.3% and 73.3%, respectively. It was concluded that QZEZECT can treat CAG precancerous lesion, which may take effect by improving and inhibiting pathologic changes of the transcription factor of inflammation.

Objective To investigate the practice status of the newNursing practice standards for intravenous therapy in secondary and above hospitals in Shandong province. Methods Self-designed questionnaire was used to investigate 3051 nurses from 129 hospitals in 17 cities in Shandong province. Results Nurses′ awareness rate of the new Nursing practice standards for intravenous therapy was 92.69%(2828/3051);92.13%(2811/3051) nurses reported that their hospitals used the new standard, 65.78%(2007/3051) nurses reported that their hospitals had applied the standard since the second half of 2014; 92.92% (2835/3051) nurses reported that their hospitals had revised their practice rules according to the new standard;93.54%(2854/3051) nurses reported that their hospitals had revised the related nursing process; 50.08% (1528/3051) nurses thought the new standard helpful to clinical practice;22.98%(701/3051) nurses knew well about the new standard;53.85%(1643/3051) nurses thought the standard applicable to clinical practice. Conclusions As nurses do not master the Nursing practice standards for intravenous therapy well, they need strengthened training. Hospitals should fresh their rules, protocolsand supply training program to improve nurses′ knowledge and skill. Meanwhile, Nursing practice standards for intravenous therapyalso needs to be revised and improved according to nurses feedback.

Objective To study the relationship between gene polymorphism of apolipoprotein E (apolipoproteinE,ApoE)of peripheral blood and Mycoplasma pneumoniae infection in children.Methods Collected 236 cases serum of inpatient and outpatient screening in children with Mycoplasma pneumoniae infection and healthy children between March 2011 and March 2014 in the First Affiliated Hospital of Xi’an Medical University and Xi’an Children’s Hospital,at the age of 3~8 years old,divided into two groups:110 cases of control group and 126 cases of Mycoplasma pneumoniae infection in chil-dren.Used multiple allele-specific PCR (multi-AS PCR)to detect gene polymorphism of ApoE in each group.Results ApoE gene was polymorphic and 6 genotypes:3 homozygous (ε2/2,ε3/3,ε4/4)and 3 heterozygote (ε3/2,ε3/4,ε4/2).Theε3/2 had four bands,ε3/3,ε3/4 and 4/2 had three bands,ε2/2 andε4/4 had two bands.ε3/3 of ApoE genotype distribution in two groups was the most common,control group was 66.7%,infection group was 46.4%.Allele frequencies ofε3 and genotype frequencies ofε3/3 inMycoplasmapneumoniae infection of children were lower than those in control group (P<0.05).But allele frequencies ofε4 and genotype frequency ofε4/4 in Mycoplasma pneumoniae infection of children were increased, which were compared with those in control group (P<0.05).Conclusion There were an association between ApoE gene polymorphism and the incidence of Mycoplasma pneumoniae infection in children.Allelesε3 seems to be a protective factor and allelesε4 may contribute to the development of Mycoplasma pneumoniae infection of children.

Objective To investigate the nurse self-directed learning readiness in some 3A hospital in Shandong province and discuss the strategies how to improve it. Methods Self-designed questionnaire and The Nurses Self-Directed Learning Readiness Scale were used to investigate 210 nurses from 23 departments in Shandong provincial hospital.

Background:China is an area with high incidence of gastric cancer,studies have shown that serum pepsinogen (PG) and gastrin-17 (G-17)levels can be used for gastric cancer screening. Aims:To investigate the values of serum PG and G-17 levels in screening gastric precancerous lesion and gastric cancer. Methods:A total of 211 patients with gastroduodenal disease diagnosed by endoscopy and biopsy from March 2016 to October 2016 at the First Affiliated Hospital of Soochow University were enrolled,and 67 healthy subjects were served as controls. Serum levels of PGⅠ,PGⅡ,G-17 and Hp-IgG antibodies were determined by ELISA. Results:Compared with control group,PGⅠ level and PGR were significantly decreased in atrophic gastritis group (P < 0. 01);serum PGⅠ level and PGR were significantly decreased, and G-17 level was significantly increased in low grade intraepithelial neoplasia group,high grade intraepithelial neoplasia group and gastric cancer group (P < 0. 01). ROC curve showed that the best cutoff values of PGⅠ,PGR and G-17 for diagnosing gastric cancer and gastric precancerous lesion were 74. 74 ng/ mL (sensitivity 88. 3％,specificity 78. 0％), 6. 59 (sensitivity 87. 0％,specificity 73. 8％),13. 02 pmol/ L (sensitivity 54. 2％,specificity 84. 4％),respectively. PGR and G-17 were the independent predictors of gastric cancer and gastric precancerous lesion. The sensitivity and specificity of combined detection of PGⅠ,PGR and G-17 for diagnosing gastric precancerous lesion and gastric cancer were 89. 9％ and 84. 4％,respectively. Conclusions:Serum PGⅠ,PGR and G-17 may be used as indicators of gastric cancer and gastric precancerous lesion screening. PG combined with G-17 for diagnosing gastric cancer and gastric precancerous lesion is more sensitive and specific than using serum PG or G-17 alone.

Objective To explore the relationships among social adaptation and the resilience,social support and coping style in undergraduate nursing students.Methods 758 students from two medical colleges in Shandong province were recruited by stratified random sampling method.They were assessed with China College Student Adjustment Scale (CCSAS),Resilience Scale for Adults (RSA),Social Support Rating Scale (SSRS),Simplified Coping Style Questionnaire (SCSQ).The data was analyzed with the structural equation mode.Results The social adaptation of undergraduate nursing students showed significantly positive association with the resilience,social support,positive coping style(r=0.113-0.607,P＜0.01),but the campus adaptation had negative association with negative coping style(r=-0.117,P＜0.01).The path analysis showed that the resilience,social support and coping style were the direct predictors of social adaptation (β=0.57,P＜0.05;β=0.0.26,P＜0.05;β=0.1,P＜ 0.05),and the resilience,active coping style played the mediating role between social support and social adaptation (β=0.31,P＜0.05;β=0.05,P＜0.05).Conclusion The social adaptation and the resilience,social support and active coping style of nursing undergraduates are closely related.

Objective To analyze the clinical features and risk factors of recurrent acute pancreatitis (RAP).Methods From September 2012 to September 2014,the clinical data of 411 patients with primary acute pancreatitis (AP) were collected.From March to June 2016,patients were followed up.The clinical features of patients with RAP were analyzed.Univariate and multivariate regression analysis were performed to analyze the risk factors of RAP.Results Among the 411 patients with AP,those caused by biliary disease,hyperlipidemia,alcohol,other known causes and idiopathic AP were 265 cases (64.5％),61 cases (14.8％),19 cases (4.6％),21 cases (5.1％) and 45 cases (10.9％),respectively.In two weeks of AP onset,the recurrent rate of biliary AP in cholecystectomy group was 7.1％ (5/70),which was lower than that of non-cholecystectomy group (30.2％,42/139),and the difference was statistically significant (xz =14.218,P＜0.01).The results of univariate regression analysis suggested that gender,body mass index (BMI),complicated with diabetes,etiology,history of smoking,history of drinking and pancreatic necrosis were correlated with RAP (all P＜0.05).The results of multivariate regression analysis indicated that complicated with diabetes (odd ratios (OR) =3.417,95 ％ confidence interval (CI) 1.979 to 5.900,P＜0.01),hyperlipidemic pancreatitis (OR=2.247,95％CI 1.077 to 4.688,P=0.023),history of smoking (OR=4.023,95％CI 2.377 to 6.809,P＜0.01),complicated with pancreatic necrosis (OR=3.312,95％ CI 1.675 to 6.546,P＜0.01) were independent risk factors of RAP.Conclusions Hypertriglyceridemia,smoking,complicated with pancreatic necrosis and diabetes are independent risk factors of RAP.Patients with biliary AP should receive cholecystectomy as early as possible,which could reduce RAP.

AIM: To investigate the active components and potential mechanism of saffron (Crocus sativus L.) in inhibiting atherosclerotic lesion by using network pharmacological method. METHODS: TCMSP database was used to systematically analyze the active components of saffron. At the same time, GeneCards and OMIM databases were used to analyze the genes and proteins according to atherosclerosis mechanism. A follow-up analysis was establishing drug-compound-disease-target network. The potential targets were analyzed for protein interactions, and gene enrichment analysis was carried out by GO and KEGG. Molecular docking was carried out between characteristic ingredients of saffron and its key targets. RESULTS: A total of 5 effective components and 272 genes were screened in saffron used oral bioavailability (OB)>30% and drug likeness (DL)>0.18 as the screening conditions. 26 targets of multiple compounds acting together and 50 targets of a single compound were screened from drug-compound-disease-target network. 19 targets, 99 enrichment results and 116 pathways were screened by protein interactions, GO and KEGG gene enrichment analysis respectively. Molecular docking results showed that all 5 active components could be bind with spontaneously VCAM-1 or eNOS, which are representative proteins of fluid shear stress and atherosclerosis pathway. Isorhamnetin had the lowest binding energy with VCAM-1, and kaempferol had the lowest binding energy with eNOS. CONCLUSION: The results preliminarily verified the main activity components and pharmacology mechanism in saffron and provided a good foundation for further study on the antiatherosclerotic mechanism of saffron.
