A quartz tube reactor was designed to combine with a commercial mass spectrometer for on-line detecting the gases evolved during pyrolysis of coal and other samples with high volatile. The reliability and repeatability of this atmosphere pressure-temperature programmed pyrolysis-mass spectrum (AP-TPP-MS) system were tested by model compound and real coal sample. The results show that pyrolysis of model compound can give good response, less overlap or tailing gases evolution curves;and multi-peaks can be observed from the same gas curve of real sample. The reliability and repeatability of this system are perfect and the system can be applied to study the coals decarboxylation by comparing the CO_2 evolution curves.

Objective:To explore the improvement effect of tirofiban on the myocardial reperfusion of non-ST segmant elevated myocardial infarction (NSTEMI) patients underwent percutaneous coronary intervention (PCI) treatment.Methods:78 NSTEMI patients underwent PCI in our hospital from April 2012 to April 2015 were selected and divided into the observation group (n=38) and the control group (n=40) according to different drugs.Patients in the control group were given asprin,clopidogrel and heparin,while patients in the observation group were additionally given tirofiban.Then the myocardial contrast echocardiography (MCE) was taken to evluate the myocardial reperfusion.Results:No statistical difference was found in the levels of A,β,A β,CK-MB and cTnⅠ before PCI between 2 groups.The levels of β,A β of observation group were obviously higher,CK-MB and cTnⅠ were obviously lower than those of the control group(P<0.05).The MACE rate of observation group was 2.63%,which was 5.00% in the control group,no significant difference was between two groups (P>0.05).Conclusion:Tirofiban could obviously improve the myocardial reperfusion of NSTEMI patients underwent PCI with high safety.

Objectives To examine the effects of enhanced external counterpulsation on arterial elasticity in stroke patients to provide clinical evidence for secondary prevention of patients with cerebral ischemic stroke. Methods Total 192 patients with ischemic stroke were enrolled and then divided into the EECP (n=107) and control (n=85) group. Auto-matic measurement synchronous atherosclerosis detector was use to measure brachial-ankle pulse wave velocity (BaP-WV) and cardio-ankle vascular index (CAVI). The difference of BaPWV and CAVI were evaluated before, at 36 hours and one month after EECP. Results The BaPWV and CAVI significantly decreased at 36 hours and 1 month after treat-ment in EECP groups compared to either pre-therapy or control groups (all P<0.05). Conclusions EECP can signifi-cantly reduce the BaPWV and CAVI and improve the arterial elasticity in patients with cerebral ischemic stroke. Thus, arterial elasticity may be an important index to evaluate the effects of EECP on cerebral ischemic stroke.

Objective To explore the therapeutic effect and prognosis of enhanced external counterpulsation (EECP)on acute cerebral ischemic stroke,to provide clinical evidence for the treatment of patients with acute cerebral ischemic stroke.Methods Total171 patients with acute cerebral ischemic stroke were enrolled and measured the NIHSS and mRS,before EECP,after36 hours EECP,and 3-month after attack.Then contrast the difference of these indicators.Result Compare with the control group,after EECP treatment and after 3-month attack,the scores of NIHSS were statistically significant,(after EECP:44.1% vs 31.5%;after 3-month attack:55.6% vs 40.5%),(P< 0.05).Compare with the control group,after 3-month attack,the score of mRS in EECP group was declined statistically significant,and the rate of favourable prognosis rise obviously (P<0.05).Conclusion EECP can effectively improve neurological function and promote health and improve prognosis in the patients with acute cerebral ischemic stroke.

Objectives To explore the effects of enhanced external counterpulsation(EECP)on the serum level of C-reactive protein and endothelin-1 in patients with cerebral ischemic stroke,to provide clinical evidence for the treat?ment and secondary prevention of patients with cerebral ischemic stroke. Methods Total 187 patients with ischemic stroke were enrolled measure the serum level of C-reactive protein and endothelin-1, before EECP, after36 hours EECP, and one-month after EECP. Then contrast the difference of these indicators. Result After treatment, the serum levels of C-reactive protein and endothelin-1 in EECP group were obviously decrease and the difference was statistically signifi?cant(hs-CRP 60.1%vs. ET-1 40.9%,P<0.05). After treatment, the serum levels of C-reactive protein and endothelin-1 in EECP group were obviously decrease than that in the control group and the difference was statistically significant ( hs-CRP 41.3%vs. ET-1 24.3%,P<0.05). One-month after EECP, the serum level of endothelin-1 in EECP group was obviously decrease than that in the control group(43.8%vs. 31.8%,P<0.05). One-month after EECP, there was no signif?icant difference in the serum levels of C-reactive protein between the two groups (P>0.05). Conclusion EECP can obvi?ously reduce the serum levels of C-reactive protein and endothelin-1 in the patients with ischemic stroke, which indi?cates that EECP can slow atherosclerotic process.

Objective To explore difference of neuropsychological tests between the remitted schizophrenia patients and the first-degree non-psychotic relatives of schizophrenia patients,and to explore the possible endophenotypes in cognitive function.Methods The MATRICSTM consensus cognitive battery was administered to 86 remittent schizophrenia patients (the patient group),86 first-degree non-psychotic relatives of schizophrenia patients (the relative group),and 86 healthy people (the control group).Results Compared with the control group,the patients group and the relative group showed poor performance on trail making test,brief assessment of cognition,hopkins verbal learning,mazes,category fluency,emotional intelligence test and continuous performance test (P<0.05).There were significantly lower performances in the patient group than the relative groups on hopkins verbal learning,mazes,emotional intelligence test and continuous performance test (P<0.05).Conclusion The remitted schizophrenia patients and their first-degree non-psychotic relatives have selective deficits in cognition function,among them,verbal leaning,attention/vigilance,reasoning and problem solving and social cognition may be potential endophenotypes for schizophrenia.
