Objective To analyze the clinical features of eosinophilic granulomatosis with polyangiitis (EGPA).Methods The clinical characteristics,laboratory test,therapeutic regimen,pathology and imaging diagnosis in 23 cases with EGPA from the First Affiliated Changhai Hospital of Second Military Medical University within June 2007 to January 2013 were retrospectively analyzed.Results There were 14 males and 9 females,with the age ranged from 21 to 68 years.The mean age was (42±9) years.The overall prevalence of asthma was 78％(18/23).The allergic rhinitis accounted for 61％(14/23).The maxillary sinuses were the most frequendy involved,which accounted for 57％(13/23).Skin involvement was 57％(13/23),peripheral neuritis was 70％(16/23).Central nervous system involvement presented cerebrovascular event.Cardiac involvement accounted for 48％(11/23),digestive system involvement accounted for 17％(4/23).The outcome of auxiliary laboratory test revealed that 96％(22/23) patients expressed significantly higher levels of IgE and 70％(16/23) patients carried anti-neutrophil cytoplasmic antibodies (ANCA) which were presented as the perinuclear ANCA (p-ANCA).The patchy infiltrates of lung CT scan accounted for 69％ (11/23).EMG showed mononeuritis multiplex and symmetric sensory motor neuropathy.The abnormal ratios of ECG and Echocardiography were 48％(11/23),79％(11/14) respectively.The pathological manifestations were necrotizing vasculitis,eosinophilic tissue infiltration,and extravascular granulomas.Conclusion Our results confirm the heterogenicity in clinical presentation and lack of specificity.Early diagnosis and treatment will be helpful for good prognosis.

Objective To explore the clinical value of dynamic electrocardiogram ( DCG) in the diagnosis of coronary artery damage (CAD) in children with Kawasaki disease (KD).Methods A total of 125 cases of children with KD admitted to hospital in recent years was analyzed , without CAD as the control group (83cases), and others as the experimental group (42cases).All cases were undertaken DCG and electrocardiogram (ECG).The results of heart rate, heart Rhythm, and voltage changes were compared be-tween two groups .Results The abnormal rate of total ECG and DCG in the control group was significantly lower than the experimental group ( P <0.01 ) , The total ECG and DCG abnormal rate was no difference in control group ( P >0.05 ) , but DCG abnormal rate of experimental group was significantly lower than ECG (χ2 =15.30, P <0.01).The sensitivity, specificity, Youden index, and diag-nostic accuracy of normal ECG , DCG and Joint were 59.5%, 86.7%, 0.463 , and 77.6%;95.2%, 94.0%, 0.892 , and 94.4 %;95.2%, 84.3%, 0.796 , and 88.0%.Common ECG results were lower than DCG and joint ( P <0.05 ) , But DCG results were sim-ilar with the joint ( P >0.05 ) .Conclusions DCG test provides scientific parameter in the diagnosis of CAD in children with KD , and is superior to normal ECG , but the value of Joint is the same .

Objective The aim of this study was to explore the effects of health education intervention on asthma control level for asthma patients through the survey of general demographic information,asthma clinical characteristics of patients with asthma,the Asthma Control Test (ACT),and pulmonary function examination.Methods 126 asthma patients were selected from the clinic and randomly divided into the health education group and the control group.All the patients were followed up for 3 months.In our study,we would scored them in terms of demographic data,clinical features of asthma,asthma cognitive level,medication compliance and Asthma Control Test (ACT) and pulmonary function examination before and after the health education for all patients respectively,and compared the data of the above parameters obtained before and after the intervention and the data from the health education intervention group and the control group.Results In our study,10 cases were lost to follow-up,and 116 cases completed the study at last.There were 68 patients in the health education intervention group and 48 patients in the control group.The results showed that patients with acute attack times,ACT score,pulmonary function indicators and asthma control situations of the health education intervention group after 6 months’ health education,were significantly improved,and the difference was statistically significant.Otherwise,comparison of the contents above of the control group before and after intervention,it was not statistically significant.Meanwhile,com-pared with the control group,the contents above of the health education intervention group were improved with statistically significant differences.Conclusions The standardized health education can improve the quality of life significantly,decrease the asthmatic symptoms,reduce the times of acute onset,which results in maintenance of asthma control,meanwhile the pulmonary function of patients with asthma will improve,so that more patients can live as normal or nearly normal people.

Objective evaluate the role of vagus nerve?muscarinic cholinergic receptor ( M recep?tor) pathway in mitigation of myocardial ischemia?reperfusion (I∕R) injury by intrathecal morphine postcon?ditioning in rats. Methods Seventy adult male Sprague?Dawley rats in which intrathecal catheters were suc?cessfully placed without complications, weighing 250-350 g, were randomly assigned into 7 groups ( n=10 each) using a random number table:sham operation group (Sham group), I∕R group, intrathecal morphine postconditioning group ( MP group) , vagal transection ( VT) group, VT+ intrathecal morphine postcondi?tioning group (VT+MP group), atropine (ATP, M receptor antagonist) + morphine postconditioning group ( ATP+MP group) , and ATP group. Myocardial I∕R was produced by occlusion of the anterior descending branch of left coronary artery for 30 min followed by 2 h of reperfusion. Morphine ( 3μg∕kg, 10μl) was in?trathecally infused over 5 min starting from onset of reperfusion in MP group. Normal saline 10 μl was in?trathecally infused over 5 min starting from onset of reperfusion in NS group. The bilateral vagus nerves were transected at 10 min before reperfusion in VT+MP group. Atropine ( 0?1 mg∕kg, 0?5 ml) was intravenously infused over 5 min starting from 10 min before reperfusion in ATP+MP group. The occurrence of cardiac ar? rhythmia ( premature ventricular contractions ( PVCs) and ventricular tachycardia ( VT)∕ventricular fibrilla?tion ( VF) ) within the first 30 min of reperfusion was recorded. The rats were sacrificed at 120 min of reper?fusion, and myocardial specimens were obtained for determination of myocardial infarct size ( IS) as a per?centage of area at risk (AAR). IS∕AAR ratio was calculated. Results Compared with Sham group, the number of PVCs and VT∕VF and IS∕AAR ratio were significantly increased in the other groups. Compared with I∕R group, the number of PVCs and VT∕VF and IS∕AAR ratio were significantly decreased in MP group. Compared with MP group, the number of PVCs and VT∕VF and IS∕AAR ratio were significantly in?creased in VT+MP and ATP+MP groups. Conclusion Vagus nerve?M receptor pathway is involved in miti?gation of myocardial I∕R injury by intrathecal morphine postconditioning in rats.

Aim To investigate the role of NO/cGMP in the cardioprotective effects of intrathecal morphine preconditioning against myocardial ischemia-reperfu-sion injury in rats. Method 54 Male Sprague-Dawley Rats were used to establish the model of intrathecal catheter placement. The rats were randomly assigned to
9 groups. SHAM (sham group), CON (control, sa-line) , ITMP ( intrathecal morphine preconditioning, 3μg·kg-1 ) , L-NAME+ITMP ( NO synthetase inhibi-tor,L-NAME ) , ODQ + ITMP ( guanylate cyclase in-hibitor, ODQ ) , KT5823 + ITMP ( PKG inhibitor, KT5823),L-NAME,ODQ,KT5823,6ratsineach
group. ITMP were produced by three cycles of 5 min intrathecal injection of morphine and 5 min intermis-sion before myocardial ischemia, CON were achieved by intrathecal injection of saline in the same way, L-NAME+ITMP, ODQ +ITMP, KT5823 +ITMP were prepared by intrathecally administering L-NAME ( 30 nmol), ODQ(11 nmol) and KT5823(20 pmol) 10 minutes prior to ITMP respectively, L-NAME, ODQ, KT5823 worked as the control of inhibitors themselves respectively without ITMP. Subsequently, all rats were subjected to 30 min of left coronary artery occlusion followed by 2 h of reperfusion except the SHAM group. Myocardial infarct size, as a percentage of the AAR,
was determined by 2 , 3 , 5-triphenyltetrazolium stai-ning. Results Compared with CON, the volumes of IS and IS/AAR were reduced in ITMP ( P <0.01 );the protective effects of ITMP were abolished by pre-treatment with L-NAME, ODQ and KT5823 ( P <0.01 );Conclusions NO/cGMP might be involved in the cardioprotective effect of intrathecal morphine pre-conditioning against myocardial ischemia and reperfu-sion injury in rats.

Objective To observe the expression of acid-sensing ion channel la (ASICla) and to investigate the effect of intracellular Ca2 + concentration on focal cerebral ischemia in diabetic rats.Methods 108 male Wistar rats were divided into three groups:group A [rats with middle cerebral artery occlusion (MCAO)],group B [rats with MCAO and diabetes (DM + MCAO)],group C [rats with MCAO and diabetes treated with fasudil intervention (DM+ MCAO+ fasudil)] (n=36 each).Samples were obtained at the time points of 1,3,6 and 24 h after ischemia respectively (n=9).Models of MCAO and DM+MCAO were prepared.Rats in DM+MCAO+Fasudil group were treated with fasudil 1 mg/Kg by caudal vein injection after half an hour when DM+MCAO model successfully prepared.ASICla expressions were detected at different time points of ischemia in the 3 groups respectively.Ca2+ concentration in ischemia cortex cells were determined at different time points of ischemia in group B and C.Results ASICla expressions were gradually increased along with the ischemia time in group A and B (group A:0.71±0.10,0.80±0.11,0.86±0.08,0.93±0.09;groupB:0.86±0.11,1.05±0.51,2.42±0.08,2.78±0.04; all P＜ 0.05),and ASICla expressions at different time points were higher in group B than in group A (all P＜ 0.05).Ca2-concentration were gradually increased along with the ischemia time in group B (106.32± 18.6,137.84±14.32,151.94± 18.38,183.61±7.96,all P＜0.05).Compared with group B,the levels of ASICla expression and calcium current were reduced in group C.Conclusions The activation of ASICla increases calcium ion flow internal pathway leading to intracellular calcium overload,which may be one of the reasons for the aggravation of focal cerebral ischemia in diabetes.

Objective To explore the effect of hospital-community-based collaborative management on elderly out-patients with chronic heart failure (CHF).Methods A total of 228 out-patients with CHF were randomly assigned to the community-based health management group (n =106 ) and the hospitalcommunity-based collaborative health management group (n =122).In community-based health management group,the patients only received community-based health management,while in hospital-community-based collaborative health management group the patients accepted comprehensive health management.One year later,medication compliance,readmission rate,mortality,average length of hospitalization,medical costs and Minnesota living with heart failure questionnaire (LiHFe) were compared between the two groups.Results No statistically significant differences in clinical data were found between the two groups at baseline.After one year,medication compliance was significantly improved in hospital-community-based collaborative health management group when compared to community-based health management group ( x2 =8.97,P ＜ 0.05 ).Readmission rate,averagelengthof hospitalizationandmedicalcostsof hospital-community-based collaborative health management group were lower than community-based health management group (x2 =9.91 ; t =3.78,3.61 ; all P ＜ 0.05 ).One year ago,the items of LiHFe including physical dimension,emotion,symptom and social dimension and total score showed no significant between the two group (t =0.42,0.81,0.66,0.44,0.41 ; all P ＞ 0.05 ).While one year later,all the scores of hospital-communitybased collaborative health management group were significantly declined( t =6.37,11.81,6.16,9.64,9.13;P ＜ 0.05 ).Mortality showed no significant difference between the two groups ( x2 =0.247,P ＞ 0.05 ).Conclusion Hospital-community-based collaborative management for health care may be a practical and valuable strategy for decreasing readmission rate and medical burden and improving quality of life of elderly patients with CHF.

AIM:Bioactive constituents were expected to be obtained from the roots of Angelica morri Hayata. METHOD:They were extracted with 95% alcohol and isolated by using column chromatography and recrystallization methods. The structures were elucidated by means of physico-chemical data and UV,IR,1HNMR, 13CNMR,and EIMS. The inhibitory effect on the constriction of rat aortic rings was induced by K+ or Ca2+. RESULT:3′S-(-)-hamaudol,3′S-(-)-Ο-acetylhamaudol,3′R-(+)-hamaudol,and (±)-hamaudol were isolated from the pieces of Radix Angelica Morri. The inhibitory rate of 3′S-(-)-Ο-acetylhamaudol and (±)-hamaudol on the above pharmacologic model appears the relation of quantity response. CONCLUSION:All the above compounds were found in this species for the first time,and(±)-hamaudol is a new. One of effect mechanisms of 3′S-(-)-Ο-acetylhamaudol and (±)-hamaudol diluted aorta could contribute to be inhibiting Ca2+ influx of vascular smooth muscle.

Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11％vs. 53.61％, P<0.05). There were no significant difference in coagulation index and fibrinolysis index before treatment between the two groups (P>0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.

Objective To explore the CT and MR features of malignant peripheral nerve sheath tumor (MPNST) of adults.Methods The CT and MRI findings of 20 patients of MPNST confirmed by pathology were analyzed retrospectively.Results Among 20 cases,the lesions were located in the lower extremities (n=4),shoulder and spine (n=4),abdomen (n=3),chest wall (n=2),mediastinum (n=2),breast (n=1),prostate (n=1),scrotum (n=1),scalp (n=1),left maxillary sinus and orbital bottom (n=1).Nineteen cases appeared as solid masses and 1 case appeared as diffuse lesion.The maximum cross section of the lesions were about 1.41 cm× 1.42 cm-17.10 cm× 18.08 cm.Sixteen cases were ill defined margin and 4 cases were well-defined margin.CT scan showed 14 cases were lower density or isodensity and with patchy inhomogeneous density.Multiple calcification were found in 2 cases and osteolytic destruction were found in 7 cases.Enhanced CT of 10 cases showed solid component and gradually delayed enhancement,while cystic lesion and necrosis were not enhancement.The tortuous arteries were displayed in 7 cases.Seven cases were performed MRI and the lesions appeared as hypo-intensity on T1WI and hypo-intensity on T2WI with obviously high intensity of cystic component.Enhanced MRI of 3 cases showed significantly heterogeneous enhancement,cyst and necrosis had no enhancement.MR dynamic enhancement of 1 case showed time-signal intensity curve was platform type.DWI showed high signal.Conclusion MPNST has certain CT and MR characteristics which are helpful to improve the diagnostic accuracy.
