Cerebral ischemic postconditioning refers to conduct a series of intermittent occlusion in order to reduce ischemia-reperfusion injury during the early reperfusion after cerebral ischemia.Because of its good prospects for clinical application,it has attracted widespread attention in recent years.This article reviews the neuroprotective mechanisms of ischemic postconditioning.

Objective: This work studied platelet-neutrophil aggregates (PNA) expression in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: Our research included in 2 groups: STEMI group, n=40 patients admitted in our hospital and Control group, n=30 normal subjects. Blood levels of PNA, platelet-monocyte aggregates (PMA) and platelet-lymphocyte aggregates (PlyA) were measured by lfow cytometry at admission and the results were compared between 2 groups. Results: Compared with Control group, STEMI group had similar blood levels of PlyA and PMA,P=0.245 andP=0.312; while increased blood level of PNA,P<0.05. Correlation analysis showed that platelet-leukocyte aggregates (PLA) level was positively related to CK-MB (r=0.4992,P<0.01) and cTnI (r=0.4365,P<0.01). Conclusion: Blood level of PLA, especially PNA was significantly higher in STEMI patients which suggested that increased PNA might be sued as a new index for AMI diagnosis in clinical practice.

Objective: To explore the relationship between endogenous estrogen level and myocardial no-reflow after reperfusion in postmenopausal acute ST-elevation myocardial infarction (STEMI) patients. Methods: A total of 100 postmenopausal STEMI patients with percutaneous coronary intervention (PCI) were enrolled and divided into 2 groups: Reflow group,n=77 and No-reflow group,n=23. Myocardial no-reflow was defined by TIMI≤2 grade or TIMI 3 grade and MBG≤2 grade after PCI. Blood levels of endogenous estrogen were examined before PCI; the relationship between endogenous estrogen level and myocardial no-reflow was assessed by Logistic regression analysis. Results: Compared with Reflow group, No-reflow group showed increased blood levels of estrone, estradiol, high sensitivity C-reaction protein (hs-CRP),P<0.05 and decreased sex hormone binding globulin (SHBG),P<0.05. Univariate analysis indicated that the length of lesion, thrombus score≥4, blood levels of estrone, estradiol and hs-CRP were positively related to no-reflow occurrence,P<0.05. Multi Logistic regression analysis presented that thrombus score≥4 (OR=4.994, 95%CI 1.987-10.518,P=0.035) and estradiol level (OR=4.091, 95% CI 1.105-8.582;P=0.046) were the independent risk factors for no-reflow occurrence. Conclusion: High blood level of endogenous estrogen was positively related to myocardial no-reflow after PCI in postmenopausal STEMI patients, which implied that endogenous estrogen might be the independent risk factor for no-reflow occurrence.

Objective To investigate the mental health status of patients with coronary artery stent implantation. Methods Symptom Checklist (SCL-90) was used to evaluate the mental health conditions of 218 patients after coronary artery stent implantation with man-machine conversation and computer evaluation. Results It was found that 48 cases in excellent mental health, accounting for 22.02%; 56 cases in good mental health condition, accounting for 25.69%; 82 cases in normal mental health condition, accounting for 37.61%; and 32 cases in poor mental health, accounting for 14.68%. In addition to the interpersonal factor, hostility and psychosis factors, the other six factors’overall average score was more than 2. More than 50% of the staff scored greater than 3, and their average positive factors were greater than 43 items in somatization, depression, anxiety and fear. Conclusion The patients after coronary artery stent implantation suffered from many psychological problems.

Objective To comprehensively evaluate the effect of health education on intervening iodine deficiency disorders(IDD) in Chinese pupils and housewives,and to provide a basis for prevention and intervention of the disease.Methods A computerized literature search was carried out in Chinese Biomedical Database (CBM),Chinese National Knowledge Infrastructure(CNKI),VIP,Wangfang and PubMed to collect articles published from 1997-2012 concerning the effect of education intervention on iodine deficiency disorders (IDD).The study was a self-controlled intervention study.Meta-analyses were performed to assess the knowledge on IDD prevention and behavior changes.Fixed and random effect models were employed to combine results after a heterogeneity test,and rate different(RD) was used as an indicator of the intervention effect.Results A total of 20 controlled before and after studies were included in our meta-analysis.The quality of individual studies was assessed by EPOC,and all studies were grade B.Because the heterogeneity was higher,each knowledge point was stratified analyzed according to the baseline rate.The results showed that the lower the baseline rate,the better the effect of the intervention.The analysis indicated that the RD for the main harm of IDD,the RD for the key measure to prevent IDD,the RD for the meaning of the pattern on the bags,and the RD for knowledge dissemination of IDD were increased by 35％,29％,27％,42％ and 47％,respectively.Conclusion Health education is helpful to Chinese pupils and housewives in improving their IDD related knowledge and their attitudes toward IDD.

BACKGROUND: The preventative capabilities of enamel demineralization, rising from the fixed orthodontic treatment, have drawn tremendous attention in recent years. Despite a variety of investigations carried out by both domestic and foreign scholars, whereas, the results of ways to reduce the incidence of demineralization are never fully satisfactory or unified. OBJECTIVE: To evaluate the inhibitory effect of Fluor protector on enamel demineralization based on clinical practices during fixed orthodontic treatment.DESIGN, TIME AND SETTING: Contrast observation was performed in the Department of Stomatology, Qingdao Second Sanatorium, Jinan Military Area Command of Chinese PLA from January 2006 to January 2009. PARTICIPANTS: A total of 132 participants (856 teeth, aged 7-18 years, average age 10.5 years, 76 females and 56 males), who had wall-developed hardened dental tissues, no tetracycline pigmentation teeth, no dental fiuorosis, or anything that constricted in their teeth, were involved in the study. And all subjects were volunteers who had signed the informed consent form and agreed to receive dental treatment and periodic review.METHODS: All the teeth were randomly divided into two groups: experimental and control groups. Teeth for the experimental group were bonded with the supporting brackets with the Fluor protectors, whereas teeth for the control group did basically the same only without the Fluor protectors. After the fixed orthodontic treatment, the supporting devices were removed, all the teeth were fully washed, and then the conditions of the tooth surfaces were observed and documented in both experimental and control groups.MAIN OUTCOME MEASURES: The detection rate of orthodontic enamel demineralization in the two groups alter the fixed orthodontic treatment.RESULTS: After evaluation of the results of both groups, the incidence rate of enamel demineralization in the experimental group (5.51%) was obviously lower than control group (15.1%).CONCLUSION: Fluor protector has a significantly positive effect on preventing enamel demineralizaUon dudng fixed orthodontic treatment.

Objective:To investigate the effect of methylphenidate on the ERP waveform of children with attention deficit hyperactivity disorder(ADHD) between responders and non-responders and it's psychological significance.Methods:ERP elicited by the continuous performance test were recorded before and under methylphenidate treatment in 28 ADHD children and their behavioral performance were collected simultaneously.Based on the behavioral results,the patients were divided into two groups:responders and non-responders.Results:After medcation,the responders' behavioral performance were significantly better,amplitude of NOGO-P3(30.24?10.78?v) were also larger than that of before treatment(20.34?11.42?v,P=0.04);No significant differences were found in the behavioral performance and NOGO-P3 amplitude before and after treatment(23.51?11.97?v/25.88?13.96?v,P=0.61) in the non-responders group.The amplitude of NOGO-N2 of the two groups did not have significant difference before and under methylphenidate treatment.Off medication,there were no differences between responders and non-responders.Conclusion:Methylphenidate can improve the ability of response inhibition in responders as well as increase the amplitude of NOGO-P3 of them.
