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.

ObjectiveTo observe the therapeutic efficacy of early acupoint stimulation and physical therapy on patients with cerebral infarction.Methods100 cases of cerebral infarction were divided randomly into the treatment group A (n=50), treatment group B (n=50) and other 50 cases were selected as the control group. The treatment group A received physical therapy, the treatment group B received acupoint stimulation and physical therapy, the control group only received routine therapy. Fugl-Meyer assessment (FMA) and Barthel index (BI) were used to assess physical function and activities of daily living (ADL) at pre-therapy and 3 months post-therapy respectively.ResultsThe scores of FMA and BI in three groups were similar at pre-therapy stage (P>0.05). The treatment groups showed much higher scores of FMA and BI than those in the control group after 3 months' follow-up (P<0.05), so were the scores in treatment group B compared with the scores in treatment group A.ConclusionEarly rehabilitation is much more effective, the therapeutic efficacy of acupoint stimulation and physical therapy is better than single physical therapy.

Objective To investigate the knowledge, attitude and behavior related to stroke and rehabilitation in the stroke patients and their relatives. Methods Questionnaires were performed in 60 stroke patients and 100 relatives. Results 71.7% patients knew "what is stroke". 40% knew "hypertension is the most risk factors of stroke". 45% patients and 41% relatives knew that the risk factors for stroke were hypertension, diabetes, hyperlipidemia, smoking and drinking. 35% patients and 29% relatives learned that the prevention of stroke should start being young. 50% patients did not understand post-stroke rehabilitation. Patients learned some to limit their smoking, alcohol, salt intake and alter their personality. More than 80% relatives wished to help the patients abstain smoking, limit fat and salt. 55% patients agreed to control the blood pressure. About 40% patients or their families did not know it was necessary to monitor the blood pressure and lipid, 70% relatives would help the patient exercise. Less than 50% patients began to treat their hypertension, heart disease and diabetes. 40% accepted low-fat diet and regular exercise. 35% measured their blood pressure and lipid regularly, or go to the hospital for the medical examination. Conclusion At present, the knowledge, attitude and behavior related to stroke and rehabilitation in stroke patients and their relatives need to be improved.
