In conclusion,the sufficient preoperational preparation,careful observation and intraoperative care,active and effective cooperation of nurses are important for the success of the operation.

Objective To summarize the characteristics of neurological symptoms in patients with aortic dissection.Methods The clinical data including symptoms,signs,and imaging of 865 consecutive patients with aortic dissection were analyzed retrospectively.Results Neurological symptoms occurred in 225 cases (26.0％) with aortic dissection.The most common symptom was dizziness (56 cases,6.5％),followed by syncope (49,5.7％),single lower limb sensory disturbances(47,5.4％),single lower extremity weakness(27,3.1％),coma (22,2.5％),paraplegia (19,2.2％),headache (13,1.5％)and hemiplegia (9,1.0％).The first manifestation of five cases was the neurological symptoms,including syncope (2),dizziness(1)and headache (2).Patients with type A aortic dissection were more vulnerable to the neurological symptoms than those with type B aortic dissection (34.6％ vs 14.7％),and the symptoms with significantly higher occurrence were syncope,coma,hemiplegia,paraplegia and lower limb sensory disturbances.Conclusion Neurological symptoms are common in patients with aortic dissection,especially in those with type A aortic dissection.

Objective To observe the hematocyte change in patients peripheral blood with severe hepatitis and to investigate its causes and clinical significance.Methods Partial parameters of peripheral blood cell in 65 patients with severe hepatitis and 52 normal individuals were analysed using blood cell counter.Results WBC number in patients with severe hepatitis was significantly higher than that in normal individuals[(8.13±4.33)×109/L vs(6.02±1.07)×109/L,P＜0.01],and PLT,PCT,MPV,PDW,RBC and Hb in the patients with severe hepatitis Were also significantly lower than that in normal individuals(P＜0.01).Conclusions Severe hepatitis can cause the hematocyte changes.It is essential to examine the hematocyte parameters in diagnosis and therapy of severe hepatitis.

Objective To investigate the clinical features of stroke in young adults with infective endocarditis (IE).Methods This is a retrospective analysis of clinical data of young patients (aged between 18 and 44 years) diagnosed with IE in Beijing Anzhen Hospital affiliated to Capital Medical University from January 2003 to March 2013.Results Three hundred IE patients (209 male and 91 female) were enrolled with mean age of (31.8 ± 7.8) years old.Fourteen of them were prosthetic valve endocarditis.All of the cases were found vegetations.The vegetations were mainly distributed in the mitral valve and/or aortic valve (262/300 patients).Congenital heart disease and rheumatic valvular disease were most frequently background diseases.Thirty-five cases (11.7％) were complicated with stroke.Among them,21 cases were with cerebral infarction (including 7 subjects with hemorrhagic transformation),9 cases with cerebral hemorrhage,3 cases with subarachnoid hemorrhage,and 2 with reasons unknown.Within the 21 cerebral infarction cases,the infarction sites were mainly distributed in internal carotid artery system with 5 cases involving bilateral internal carotid artery systems and 2 vertebro-basilar artery systems.As to the cerebral hemorrhage,lobar were the bleeding sites in all cases,and mainly distributed in internal carotid artery system.The proportions of left-sided endocarditis and rheumatic valvular disease were significantly higher in patients with stroke than those without [100.0％ (35/35) vs 86.4％ (229/265),P =0.02;22.8％ (8/35) vs 6.4％ (17/265),P =0.001,respectively].Regression analysis showed that the OR of the rheumatic valvular disease for stroke in young IE patients was 4.950 (95％ CI 1.626-15.072),and the OR of stroke for death was 8.387 (95％ CI 1.997-35.225),respectively.Conclusions Stroke is common in young patients with IE.Cerebral infarction often involves multiple vascular systems,and is prone to hemorrhagic transformation.Intracerebral hemorrhage often occurs in lobar.Rheumatic valvular disease might be a risk factor for stroke in young patients with IE,which is an independent risk factor for death of these patients.

Objective To study the effect of continuous drainage of subglottic secretion on ventilator associated pneumonia (VAP).Method One hundred and thirty two patients undergoing continuous drainage of subglottic secretion were divided into the control group(n=70)and the experiment group(n=62):the former group underwent sputum suction in case of bucking,wheezy phlegm or decreased oxygen saturation and the latter continuous drainage of subglottic secretion.The incidence of VAP was compared between the two groups.Result The incidences of VAP in the experiment and control groups were 17.7%and 32.9%,respectively, with significant difference between the groups(χ2=3.928,P﹤0.05).Conclusion The continuous drainage of subglottic secretion can effectively reduce the incidence of VAP.

Objective To establish a GC analytical method for the determination of N-ethyl morpholine in the air of workplace.Methods N-ethyl morpholine in the air of workplace was collected by silica gel tube, desorbed by ethanol, and according to The Criterion of Detection Methods for the Air of Workplace, the linearity range, precision, accuracy and limit of detection were determined by the GC under a certain experimental condition and the experiments of sampling efficiency , the desorption efficiency, penetrating capability and the stability of sample were carried.Results The linear range of N-ethyl morpholine was 0.025-20 mg/ml(r=0.999 8);Relative standard deviations were 3.2%-3.9%;the rates of recovery were 101.00%-102.43%(n=18), the limit of detection was 0.49 ?g/ml, the desorption efficiency was 96.10%-98.73%, the penetrating capability was 14.37 mg(100 g silica gel), and the content of samples were reduced less than 10% percent at the ninth day.Conclusion The method has higher sensitivity, better precision, accuracy, simple sampling, accurate and stable results.It can be used as an effective monitoring method to detect N-ethyl morpholine in the air of workplace.

There are two kinds of treatments on Alzheimer's disease (AD) rat by transplanting neural stem cells (NSCs),i.e.the replacing cell curing and the gene therapy.By replacing method,the AD rats showed signs of recovering to some extent on both histomorphology and behavior after transplanting NSCs into their brains.Transplanting NSCs along with the nerve nutrition factor (NTFs) showed better curative effects than NSCs transplantation alone.However,little is known about the molecular mechanism involving in the development of NSCs in vivo conditions.And the blindness of the treatment hindered the comparison of various affecting factors.The NSCs gene therapy is still in initial studying,with the effects of both cell replacement and gene therapy.This treatment genetically modified NSCs mainly by unitary nutrition fators such as nerve growth factor (NGF),brain-derived neurotrophic factor (BDNF),and glial cell line-derived neurotrophic factor (GDNF).And it was almost known nothing about the exogenous gene expression efficiency,the induce differentiation,the restore of function and security after genetically-modified NSCs transplanted into the AD rat brain.The detecting technology of NSCs transplanting curative effects of the AD rat is unitary at present.And the combined method is the developing trend,such as combining the immunohistochemical method with in vivo-tracking,and combining morphology index with the function index.

Objective To explore the effect of early melodic intonation speech training on Broca aphasia. Methods 22 patients with Broca aphasia were trained with the early melodic intonation training program. They were evaluated with China Rehabilitation Research Center aphasia examination before and after the treatment. Results There were significant differences in auditory comprehension, repetition, oral reading, speaking, reading and calculation (P<0.05), but no significant difference in description, copying, and dictation (P>0.05). Conclusion Early melodic intonation speech training can improve the speech and reading in patients with Broca aphasia.

Objective To investigate the serum concentrations of protein-bound uremic toxins of hippuric acid ( HA) , indoxyl sulfate ( IS ) , p-cresyl sulfate ( PCS ) and 3-carboxy-4-methyl-5-propyl-2-furanpropionic acid ( CMPF ) in patients with chronic kidney disease(CKD) 3-5 stages(CKD3-5) and to assess the correlation between renal function and pro-tein-bound uremic toxin concentrations in CKD3-5 patients.Methods Serum concentrations of HA, IS, PCS, and CMPF from 60 healthy volunteers and 112 CKD3 -5 patients were measured by liquid chromatography mass spectrometry/mass spectrometry ( HPLC-MS/MS ) .Correlation analysis was conducted between the levels of HA, IS, PCS, CMPF and the estimated glomerular filtration rate( eGFR) .Results Compared with healthy subjects, serum concentrations of these four solutes were significantly increased in CKD3-5 patients (all P<0.01).The serum levels of HA,IS and PCS in CKD3-5 patients were significantly increased (all P<0.05),while those of CMPF did not significantly change (P>0.05).Linear correlation analysis showed that HA, IS, PCS and CMPF were in significantly negative correlation with eGFR.The curve regression analysis showed that the curvilinear regression fitting equation was Y=-46.171lnX+209.464(R2 =0.601,P<0.01)for HA and eGFR, Y=-62.570 lnX+279.537(R2 =0.633,P<0.01)for IS and eGFR, Y=-84.297 lnX+383.172(R2 =0.529,P<0.01)for PCS and eGFR, and was Y=-7.648 lnX+53.546(R2 =0.172,P<0.01)for CMPF and eGFR .Conclusion The levels of the four types of protein-bound toxins in CKD3-5 patients increase significantly compared to healthy subjects.The serum levels of HA,IS and PCS are increased when the renal function decreases, but the level of CMPF changes little.Renal dysfunction can lead to significantly elevated levels of HA,IS and PCS in CKD3-5 patients, but has little effect on CMPF.

Objective To assess the safety and the efficacy of endoscopic ultrasound (EUS)-guided transmural drainage of pancreatic pseudocysts (PPC).Methods A total of 17 patients with PPC who underwent EUS to detect the optimal site and depth of puncture.The needle was punctured into the PPC cavity through endoscopic biopsy hole,cyst fluid was drained with a syringe.The guide wire was inserted along the pinhole under X-ray,and then the needle-knife was sent along the guide wire to cut the gastric wall and pseudocysts wall,followed by balloon dilation.The way of drainage was selected according to the cyst fluid properties.The technical success rate,treatment success rate,complication occurring rate and the skills were evaluated.Results Four patients were with nasalcystic catheter drainage,9 patients with double pigtail stents internal drainage,and 4 patients with nasal-cystic catheter and double pigtail stents combination drainage.The treatment success rates were 3/4,7/9,and 4/4 respectively.Only 1 patient subsequently developed bleeding from puncture site after stent successively placed,and was turned to surgery because of ineffective endoscopic treatment.Infection occurred in 4 patients during drainage,two of those were switched to surgical resection due to poor medical treatment response,and the other 2 were cured with intravenous infusion of antibiotics sensitive to cyst fluid bacteria and metronidazole rinse PPC.The median follow-up duration was 28.5months,and there was none of recurrence.Conclusions EUS-guided transmural drainage of PPC is safe.Stent placement and nasal-cystic catheter play an important role in PPC treatment.
