High mobility group box-1 (HMGBI)is a kind of non-histone chromatin-binding protein in nucleus.HMGB1 is intimately associated with the regulation of transcription,inflammation and rheumatic disease through binding the receptor.Recently,HMGB1 is overexpressed in several malignant tumors,and the expression level is positively correlated with the degree of differentiation,tumor invasion and metastasis.HMGB1 may be a new target molecule of antitumor.

Objective:To investigate the mobile phone dependence college students'features of detection of different facial expressions and give suggestion to future intervention for mobile phone dependence students.Methods:Totally 548 college students were assessed with the Mobile Phone Addiction Tendency Scale (MPATS).Two groups were screened by cluster analysis and high and low group standard,namely,mobile phone dependence group and control group,40 participants in each.A visual search task was used to examine the efficiency of facial processing.Participants searched displays of schematic faces and were required to determine whether the faces displayed were all the same or whether one was different.Results:When the expressions of the faces were the same,the main effect of number of faces was significant [F(1,468) =11.26,P ＜ 0.01],the detection of four faces was faster than that of eight faces [(1079.1 ± 187.9) msvs.(1139.2 ±202.7) ms].When the expressions of the faces were different,the main effect of expression types was statistically significant [F (1,312) =10.30,P ＜ 0.01],the detection of sad faces was faster than that of happy faces [(941.0 ± 168.5) ms vs.(997.8 ± 152.7) ms,P ＜ 0.01].The types of expressions had significant interaction with groups of participants [F (1,312) =16.55,P ＜ 0.01],mobile phone dependence group detected the sad faces significantly faster than the control group [(975.5 ± 112.4) ms vs.(906.4 ± 126.5) ms,P ＜0.05].Conclusion:The detection of sad faces is faster in those with mobile phone dependence than in controls.The detection of the sad and happy faces are serial search in both groups.

Inflammation is a defensive reaction and the most common pathological manifestation of dry eye.In addition,excessive inflammatory response is considered to be the most common pathogenic factor and main cause of dry eye.Currently,the active mechanism of anti-inflammatory drugs has been well-known,and topical antiinflammatory therapy for dry eye is exerting a role at certain extend.However,some adverse responses of these drugs are emerging during the treating procedure.Therefore,it is emphasized that a large sample size of and multicenter randomized-controlled clinical trial is needed to identify the different effects of various anti-inflammatory drugs for different types of dry eye diseases,which will offer a basis for standardized anti-inflammatory treatment for dry eye.

Objective To explore the changes of amplitude integrated electroencephalogram (aEEG) during brain development in premature.Methods One hundred and forty-eight premature (gestational age 28-36 weeks) were selected.According to their gestational ages,148 premature were divided into 28-30 weeks group(40 cases),with 21 male,19 female;＞30-33 weeks group (49 cases),with 25 male,24 female;＞33-36 weeks group (59 cases),33 male,26 female.At the same time,40 cases of gestational age 37-40 weeks full-term newborns were selected as control group,with 23 male,17 female.Olympic CFM 6000 cerebral function monitor(produced by the American Natus company) was used to detect the changes of their aEEG,and analysis of the changes of aEEG were conducted.The first monitor was performed 3 days after birth,then once a week,monitoring for 2 hours each time,till the premature were discharged from hospital.The average of the monitoring data was obtained as a result for the analysis,and data analysis was conducted by using SAS 9.0 statistical software.Results The sleep-wake cycle continuity voltage positive rate and cycle occurrence rate of the 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature were significantly lower than those of the 37-40 weeks full-term newborns (all P ＜ 0.05).The 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature spectrun lower bound voltage value of quiet sleep cycle and activity sleep cycle were significantly lower than those of the 37-40 weeks full-term newborns (all P ＜ 0.05).The 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature spectrum width of quiet sleep cycle and activity sleep cycle were significantly wider than the 37-40 weeks full-term newborns (F =13.444,11.982,all P ＜ 0.05).The 28-30 weeks,＞ 30-33 weeks,＞ 33-36 weeks premature total duration of sleep cycle were significantly higher than the 37-40 weeks full-term newborns (F =12.451,P ＜ 0.05).Conclusions With the increase of gestational age,premature brain development becomes gradually mature,and aEEG can reflect the degree of premature brain development to some extent.

Objective To apply the hydrocolloid dressings and hydrocolloid dressings combined GreenCream Dressing for central venous catheterization fixing, and to explore the effect of hydrocolloid dressings combined GreenCream Dressing in the prevention of venous catheter bacterial colonization and bacterial infection. Methods 470 patients who underwent the Inferior vena cava catheter were divided into 230 patients in the control group and 240 patients in the experimental group. The control group was fixed with hydrocolloid dressings after central venous catheter, and the experimental group was fixed with hydrocolloid dressings combined GreenCream Dressing after central vein catheter. The measurements included catheter bacterial colonization, catheter-related infections (CRIs) and catheter related blood stream infections (CR-BSIs), pathogenic bacteria colonization of the skin. At the same time, the skin safety was also confirmed. Results In the control group, 230 cases were retained for 1 419 catheter-days, and 240 cases in the experimental group were retained for 1 675 catheter-days. Compared with hydrocolloid dressings, hydrocolloid dressing combined GreenCream Dressing could reduce the incidence of CRIs from 1.8‰(3/1 675) to 0.7‰(1/1 675), and CR-BSIs from 2.4‰(4/1 675) to 0.7‰(1/1 675) respectively, with the statistically significant (χ2=6.39, 95%CI 1.30-31.41, andχ2=6.21, 95%CI 1.56-40.82;P<0.05). The results of bacterial colonization, CRIs and CR-BSIs showed that the most common bacteria were Staphylococcus and fungi. At the same time, compared with the hydrocolloid dressing, hydrocolloid dressing combined GreenCream dressing could reduce the incidence of skin pathogenic bacteria colonization, from 41.74%(96/230) to 28.33%(68/230),with the statistically significant (χ2=9.29,P=0.00);There was no difference between the two groups in the field of the incidence of abnormal skin manifestation (χ2=1.23, P=0.30), showing a good safety. Conclusions Hydrocolloid dressing combined GreenCream Dressing would be more effective to prevent bacterial colonization and bacterial infection of central venous catheter in department of neurosurgery.

Objective To investigate the protective effect of pretreatment with Shenfu injectio(SFI)on myocardium against ischemia-reperfusion(I/R)injury in diabetic rabbits.Methods Forty healthy adult male rabbits weighing 2.4-3.2 kg were used in this study.Type I diabetes mellitus was induced by intravenous alloxan 120 mg?kg~(-1) and confirmed by fasting blood glucose＞11.1 mmol?L~(-1).The animals were randomly divided into 5 groups(n=8 each):groupⅠsham operation;groupⅡI/R and groupⅢ,Ⅳ,ⅤSFI+I/R.I/R was produced by occlusion of the anterior descending branch of left coronary artery(LAD)for 60 min.The occlusion of LAD was then released for reperfusion.In sham operation group(Ⅰ)LAD was exposed but not occluded.In groupⅢ,ⅣandⅤSFI 5,10 and 15 ml?kg~(-1) was givenⅣrespectively 30 min before myocardial ischemia.MAP,HR,left ventricular developed pressure(LVDP),?dp/dt_(max),left ventricular end-diastolic pressure(LVEDP)and Vmax were recorded immediately before ischemia(T_0,baseline),at 5 min of ischemia(T_1),immediately before reperfusion(T_2)and at 5,15,60,90,120 min of reperfusion(T_(3-7)).The animals were killed and hearts removed for determination of infarct size and microscopic examination of the ultrastructure of LAD using transmission electron microscope.Results MAP,HR,LVDP,?dp/dt_(max) and Vmax were significantly decreased while LVEDP was significantly increased during reperfusion as compared to the baseline values at T_0 in I/R group. I/R produced myocardial infarct and damage to the endothelial cells of LAD.The harmful effect of I/R was attenuated by different doses of SFI.SFI 10 ml?kg~(-1) provided best effect.Conclusion Pretreatment with SFI can protect the myocardium against I/R injury in diabetic rabbits.SFI 10 ml?kg~(-1) produces better effect.
