Objective: To investigate the impact of clopidogrel or aspirin resistance on major adverse cardiovascular events (MACE) in elderly patients with acute coronary syndrome (ACS) and to explore the application value of thromboelastogram (TEG) in antiplatelet therapy. Methods: A total of 177 ACS patients admitted in our hospital from 2012-09 to 2014-12 were enrolled. The patients were at the mean age of (70.4±10.7) years, all of them received TEG and coagulation function test. Based on the reaction of antiplatelet therapy, they were divided into 2 groups: Non-resistance group,n=98 and Resistance group,n=70, which was further divided into 2 subgroups as Maintenance dose subgroup,n=39 and Increased dose subgroup,n=40. The patients were followed-up for 3 months to observe MACE occurrence including cardiovascular death, angina recurrence, ischemic stroke, myocardial infarction, acute thrombosis and hemorrhage. Results: In Resistance group, there were 50/79 (63.3%) patients with aspirin resistance and 29 (36.7%) with clopidogrel resistance. Compared with Non-resistance group, Resistance group showed decreased coagulation time, clot formation time, TEG reducing rate after 30 minutes maximum amplitude (LY30), activated partial thrombin time (APTT), thrombin time (TT) and international normalized ratio (INR), allP<0.05; while increased levels angle, maximum amplitude of TEG, coagulationindex, ifbrinogen and D-dimer, allP<0.05. Compared with Non-resistance group, Resistance group had the higher MACE rate 21.5% vs 7.1%,P<0.05; in addition, Increased dose subgroup had the lower MACE rate than Maintenance dose subgroup 17.5 vs 25.6%,P<0.05. Conclusion: Clopidogrel or aspirin resistance had the higher incidence of MACE in elder ACS patients; TEG was helpful for guiding antiplatelet therapy and reducing MACE incidence.

Objective To study the follow-up value of MRI in the sequela hypoxic-ischemic encephalopathy(HIE).Methods MRI features of HIE in 81 neonates were analyzed retrospectively,every child had two cranial MRI scans,the first scan at the end of the newborn stage,the second scan at 4 months to 4 years.There were 66 full-term neonates and 15 preterm neonates.Results Of 81 cases,79 cases were abnormal on second MRI examination,including myelinogenetic abnormal in 59 cases(72.8%),external hydrocephalus(EH) in 53 cases(65.4%),brain malacia in 26 cases(32.1%),cerebaral atrophy in 25 cases(30.1%),white matter decrease in 24 cases(29.6%) and dysplasia of corpus callosum in 9 cases(11.1%).EH(26/35cases) and myelinogenetic abnormal(16/35 cases) in mild HIE group,brain malacia(12/29 cases) in moderate HIE group,cerebaral atrophy(16/17 cases) and white matter decrease(15 /17 cases)in severe HIE group were often seen.Conclusion MRI findings can reflect the pathological changes of sequela of HIE,and provide objective basis for diagnosis and assessment of prognosis.

Objective The aim of this study is to provide guidance on rehabilitation nursing via observing the effect of comprehensive relaxation training on perioperative psychological stress in patients with coronary intervention treatment. Methods In this study, eighty patients ready to receive coronary intervention were randomly divided into the experimental group and the control group (40 patients in each). The control group were treated with routine percutaneous coronary intervention care, and the experimental group received both comprehensive relaxation training and routine care. The anxiety state and subjective feelings on comprehensive relaxation training in both groups were dynamically investigated via State-Trait Anxiety Inventory questionnaire and subjective feeling questionnaire from pre-operation to 7 days after operation. Results Anxiety levels between two groups showed the similar trend, and there was statistically significance between two groupsin the state anxiety level. The subjective feeling in the experimental group improved. Conclusions The psychological stress in patients receiving coronary intervention surgery maintains at high level form pre-operation to 24h post operation, and comprehensive relaxation training can significantly reduce the level of state anxiety. These patients consider that this simple training shows obvious relaxing effect.

Objective To study occupational hazards effects of electric welding,and evaluate protective measurements for different occupational hazards. Methods During 2008,occupational health services for 11 factories with shield carbon-dioxide arc welding work were provided,including surveillance of the work environment and surveillance of workers’health. Surveys of workers’health through various types of health examinations were carried out. Four hundred and thirty-three welding workers of 11 factories were included. Results The concentrations of 17 welding fume samples and 6 manganese dioxide samples were over the released limits of national standard,the maximum was 5.5,1.6 times of the limit respectively. The exceeding standard rate. of welding fume had positive correlation with the density of welding equipment(r= 0.72,P=0.01) and negative correlation with the ventilation area(r =-0.63,P =0.04) .The examination results showed that nobody suffered occupational diseases or occupational contraindications. Conclusion For the environmental risk factors existed in the electric welding operation site,more attention should be paid to the potentially occupational adverse effects of electric welding.

Objective To investigate the status of wastewater treatment of hospital sewage in Jinan. Methods The indices of COD, NH3,N and PO43- in sewage discharged from 16 hospitals before and after treatment and the content of residual chloride and fecal coliform counts in treated sewage were monitored in 2002 in Jinan. The monitoring results were evaluated according to the Criteria for Wastewater Discharge (GB/T8978-1996) and compared with the analytic results obtained in the year 2001.
