Objective To determine whether an environmental intervention tailored to each patient's allergic sensitization and environmental risk factors could improve asthma-related outcomes. Methods Irritant or allergen sensitivity determined by the patient's exposure history and confirmed with skin test. Patients were asked to record 2-week days without symptoms, days off-work(or school) and ?2-agonist puffs. Pulmonary function was also examined. Ninety-six asthmatics with atopic asthma (aged 16-78 years) were randomly assigned to a control group, an intervention group that received an educational handout monthly for 2 months. Asthmatics of both groups inhalded budesonide at a daily dose 200-800 ?g and ?2-agonist as needed. Environmental intervention lasted six months and included education and remediation for exposure to allergens. The control group had no special recommendations. Results The intervention group had more days without symptoms compared with the control group (13.4 vs.10.1days, P

The cardiovascular disease, accompanied by psychological disorder frequently, often re-quiresphysical and mental (double heart) treatment. The clinical teaching of cardiovascular graduate stu-dents is very important for cultivating qualified cardiovascular doctors. According to present situation, we improved the diagnosis rate and the doctor-patient communication skills by the strengthening of learning thedouble heart theory, the analysis ofdouble heart typical cases, and the clinical practice of double heart medical model. Accordingly, we enhanced the consciousness of double heart, which is helpful to reducing the conflicts between doctors and patients, promoted the rational use of medical resources, and fi-nally promoted the application ofdouble heartmedical model in clinical practice.

Objective To study the effect of autonomic nerve activity on emotion experience.Methods 71 healthy males were asked to see a neutral film STICK and conduct a computer game,then evaluated emotion experience.All participants were recorded skip temperature,skin conduction,heart rate,LF and HF during baseline and game periods.Results (1) There was significant difference in fear experience among high,middle and low synchronous groups (2.64 ± 2.05,2.50 ± 2.01,4.46 ± 2.41; P< 0.01),and low synchronous group was significantly higher than high synchronous group (P < 0.01).The main effects of three periods were significant in basis of three response types of autonomic nerve activity(skin conduction:F(2.68) =76.083,P<0.01; heart rate:F(2.68) =71.692,P < 0.01),and skip temperature,skin conduction and heart rate were no significant difference among three response types.Types and periods had no significant interaction.(2) Different response modes of autonomic nervous system has different distributions in high fear and low fear groups (x2 =9.763,P < 0.01).Skip temperature,skin conduction and heart rate were no significant difference between high fear group and low fear group.Conclusion The modes of autonomic nervous system have an effect on intensity of fear experience,but not the same in skip temperature,skin conduction and heart rate.

Three-orientation medical talent training mainly include humanistic quality cultivation, professional quality and physical and mental quality. With professional ability as the guidance of profes-sional quality education requires students not only to grasp skilled medical technology, but also have the ability to enhance the medical technology. Based on the orientation of training target, this research mainly from habit set, authority set, set the multitude and empirical mind-set four aspects in this paper, the critical thinking, and put forward problems from finding problems, and expounds the innovative thinking of concise problem.

The silent cerebral infarct is an clinic symptom that is so slight or transitory as to be easily neglected. There are only neural symptoms and signs,but irresponsible infarct focus can be seen on image. The risk factors of silent cerebral infarct may be the same as those of symptomatic cerebral infarct. Such infarct is likely to influence the course, clinic symptom and prognosis of acute cerebral infarct and may foretell symptomatic cerebral infarct and deteriorate into pseudo-global paralysis or multi-infarcted dementia. Therefore elder who suffer from hypertension or diabetes and experience vertigo, headache, language barrier but without apparent signs and symptoms should receive cerebral CT or MRI. Minor or third-degree precautionary measures can be taken as a chief therapy for cerebral infarct. Alternatively vitamines B_6,B_(12) and folic acid can be supplied to reduce the chance of hyperhomocysteinemia. Headache is the initial symptom in silent brain infarct. Magnesium is effective when dehydration does not work.

Background Many studies and clinical trials of pharmacologic vitreolysis are already under way to try to improve vitreo-retinal surgery and to liquefy and detach the vitreous from the retina ultimately, including chondroitinase,hyaluronidase,dispase and plasmin. However, there has not been any report on purification of human plasminogen from cord blood plasma and inducing posterior vitreous detachment of the animal eye at present.Objective This study was designed to isolate and purify the production of human plasminogen (Plg) from cord blood plasma with ethanol precipitation and evaluate the efficacy of Plg in inducing posterior vitreous detachment (PVD).Methods Human Plg was Separated and purified from cord blood plasma by ethanol precipitation method. The protein band corresponding to Plg with molecular mass of 92 000 was revealed in SDS-PAGE and confirmed by MALDI-TOF and Mascot database. Anion-exchange chromatography and plasminogen activity assay kit were used to obtain purified Plg with biological activity. Twenty-five fresh pig eyes were enucleated and assigned to 5 groups and 5 eyes for each group. The normal eyes were used as control group. Balanced salt solution(BSS)of 0.1 ml was intravitreally group and standard substance group. All of the eyes were then incubatedfor 60 minutes under the 37 ℃. Retinal histopathology and ultrastructure were examined under the light microscopy, scanning electron microscopy ( SEM ) and transmission electron microscopy (TEM). Results The Plg with potential fibrinolytic activity was successfully extracted and purified from cord blood plasma by ethanol precipitation method. No posterior vitreous detachment (PVD) was seen in normal control group, BSS group and r-SK group following the intravitreal injection under the sem. However,PVD was demonstrated in r-SK+ Plg group and standard substance group under the SEM. The inner limiting membrane ( ILM ) and the retina were well preserved in all of the experimental eyes. No retinal morphology and ultrastructural abnormality were found under the light and SEM and TEM. Conclusion Ethanol precipitation is a feasible way to isolate and purify Plg from human cord blood plasma. Extracted Plg shows potential fibrinolytic intravitreal injection of Plg.
