Objective To investigate the major clinical manifestations and their effect on prognosis in patients with posterior circulation stroke (PCS).Methods The clinical data of 129 consecutive hospitalized patients with acute PCS confirmed by clinical and imaging were registered prospectively,and they were followed up for 3 months.The patients were divided into a good prognosis group (modified Rankin scale [ mRS] score ≤ 2) and a poor prognosis group (mRS score ≥ 3) according to their mRS scores.Results 90.7％ patients had 4 to 12 symptoms and signs,only 1 presented an isolated symptom.The most common symptoms and signs were unilateral.Crossed paralysis (1.6％) or quadriplegia (0.8％ ) was rare.Univariate analysis showed that the symptoms of unilateral limb weakness (relative risk [RR] 1.262,95％ confidence interval [ CI] 1.030-1.546; P =0.030),slurred speech (RR 1.434,95％CI 1.133 - 1.816; P=0.004),dysphagia (RR 2.216,95％ CI 1.131 -4.341; P =0.017),and the signs of decreased unilateral muscle strength (RR 1.288,95％ CI1.047-1.583; P=0.021),central facial/tongue paralysis (RR 1.467,95％CI 1.164- 1.850; P=0.002),dysarthria (RR 1.468,95％CI 1.154- 1.867; P=0.002),ocular motor dysfunction (RR 3.073,95％CI1.346 - 7.017; P =0.005),and conscious disturbance (RR 5.736,95％ CI 1.268 - 25.946; P =0.023) were the risk factors for poor prognosis,while ataxia (RR O.478,95％ CI 0.284 -0.804; P =0.002) was associated with good prognosis.Multivariate logistic regression analysis demonstrated that after adjusted for all risk factors,the baseline National Institutes of Health Stroke Scale (NIHSS) (odds ratio [ OR] 1.513,95％ CI1.107-2.066; P=0.009),dysarthria (OR,7.11,95％ CI 1.207-41.877; P=0.030),ocular motor dysfunction (OR 8.653,95％ CI 1.230- 60.887; P=0.030),and large-artery atherosclerotic stroke (OR5.482,95％ CI 1.008 -29.803; P =0.049) were the independent risk factors for poor prognosis in patients with PCS,while ataxia (OR 0.251,95％ CI 0.067- 0.941; P=0.040) was independently associated with good prognosis of the patients.Conclusions The clinical manifestations in patients with PCS are complex,the majority of their symptoms and signs are unilateral.Most of the patients showed a variety of symptoms,and the isolated symptoms axe rare.Some symptoms and signs may indicate the prognosis of patients.

Objective To investigate the major risk factors of posterior circulation infarction.Methods Clinical data from 216 patients with posterior circulation infarction were analyzed retrospectively. The patients were divided into follow groups (proxima1,middle, dista1 and combination group,or single , multiple, or unilateral, bilateral, or lacune infarct, non lacune infarct ) according to the infarcts locations on MRI.The risk factors in each group were analysed. Also,the major risk factors were compared with that from patients with anterior circulation infarction. Results In 216 patients with posterior circulation infarction, hypertension was the most common risk factor (76.9%), followed by diabetes mellitus (36.6% ),hyperlipedemia (30.1%), previous stroke history(26%), and heart disease(22.2%). The most common location of infarcts was distal territory (49%),followed by middle(24.5%) ,proxima1(6%). The average age of proximal group [(57.92?12.81) years] was significant lower than that of other groups(P

Objective To dieuss clinical manifestations of the organs damage out of lung caused by my-coplasma pneumonia(MP) infection in children. Methods Clinical date of 383 children with mycoplasma pneumonia infection were retrospectively reviewed. Results Among 383 cases, a total of 81 cases(21.25 %) were accompanied by organs damage out of lung. Conclusion The organs damage out of lung were observed in many system, the rate of organs damage out of respiratory tract is high in children. Mistake may occur easily in diagnosis if the symptoms out of lung appear first.

objective To describe the clinical features of patients with posterior circulation ischemic stroke.Methods 216 patients with posterior circulation ischemic stroke admitted in our department during 2004-2006 were analyzed retrospectively.All patients were undertaken MRI on admission and responsble lesions were identified at the posterior circulation territories.The patients'clinical symptoms and signs were evaluated and the relationships between lesion locations and clinical characteristics were analyzed.Results The common symptoms of posterior circulation ischemic stroke were unilateral limb Weakness(81.9%),speech difficulty(46.3%),dizziness(33.8%),and unilateral limb numbness (31.O%).The common signs of posterior circulation ischemic stroke were unilateral limb weakness (81.9%),central facial or lingual palsy(61.1%),dysarthria(46.3%),unilateral limb sensory loss (31.0%),and ataxia(30.1%).The incidence of crossed paralysis was low(2.8%).Isolated vertigo was rare (1.4%).Predominant clinical features such as bulbar paralysis,unconsciousness,visual disorder and amnesia can help to localize the lesions.Typical brainstem syndromes had topographic meanings.Conclusions The clinical features of patients with posterior circulation ischemic stroke were complex.Predominant symptoms can help to diagnose the posterior circulation ischemic stroke.

OBJECTIVE:To analyze the blood concentration monitoring data of 4 commonly used antiepileptic drugs(AEDs, sodium phenytoin,carbamazepine,sodium valproic acid,oxcarbazepine)in order to provide reference for rational use of drugs in the clinic. METHODS:415 patients underwent 4 AEDs blood concentration monitoring were selected from our hospital during 2014-2015,and the results of blood concentration monitoring were analyzed statistically. RESULTS:There were 680 cases of AE-Ds blood concentration monitoring in total. The main objects of serum concentration monitoring were young and middle-aged(range from 19 to 60),involving 449 cases in total(66.03%). 360 cases were in the normal range(52.94%). Among 361 patients receiving single drug therapy,the rates of serum concentration in the normal range were 80.77%for carbamazepine,which was higher than oth-er 3 AEDs(30.00% for sodium phenytoin,47.40% for sodium valproic acid and 40.38% for oxcarbazepine),with statistical signifi-cance(P<0.05). Among 54 patients receiving combination therapy,the serum concentration monitoring data of 67.65%patients treat-ed with double-combination therapy and 100%patients treated with triple-combination therapy deviated from normal range. CONCLU-SIONS:The rate of AEDs blood concentration reaching the normal range are in low level in our hospital. It’s necessary to strengthen medication education for patients to improve the compliance of patients;clinical efficacy of AEDs is evaluated on the basis of blood concentration monitoring and clinical symptom,and combination therapy should be avoided as much as possible.

Objective To evaluate the efficacy of donepezil for post-stroke aphasia. Methods Sixty patients with acute post-stroke aphasia were divided into treatment group and a control group. All patients had been treated for secondary prevention according to the guideline. The treatment group received donepezil hydrochloride (5 mg/d) for 12 weeks. The efficacy of treatment was measured by comparing the changes of scores of Western Aphasia Battery ( WAB) between baseline and 12 weeks later. Results Compared with the baseline, the changes of scores of all items of WAB and Aphasia Quotient ( AQ) in both group after 12 weeks follow-up were great, however, the change of AQ was significantly greater in donepezil group (34. 14 ± 17. 70) than that in control group (20. 69± 17. 26) (P =0. 004). The patients in donepezil group also showed significant recovery in spontaneous speech, comprehension, repetition, and naming than those in control group (P <0. 05 ). The rate of significant improving in donepezil group was 60. 0% which was significantly greater than that in control group ( 26. 7% ) ( P = 0. 009 ). Conclusion There are spontaneous recovery of post-stroke aphasia within 3 months. Donepezil may facilitate the recovery in spontaneous speech, comprehension,repetition,and naming functions.

Objective To respectively analyze the patterns and possible predictors of recurrent strokes among patients with initial ischemic stroke.Methods Three hundred and sixty-one patients with recurrent strokes (acute ischemic stroke or intracerebral hemorrhage) after initial ischemic strokes were collected from Jan 2004 to Dec 2009.The data about conventional risk factors such as smoking,heavy alcohol drinking,hypertension,diabetes,hyperlipidemia,heart diseases,head trauma,migraine,family history of cardiovascular disease,and the use of preventive medications were collected and analyzed among patients with different types of recurrent strokes.Results Patients (n =361) were divided into ischemic stroke group (n =321) and hemorrhagic stroke group (n =40) according to the recurrent stroke type.The ischemic stroke group was further divided into the anterior circulation stroke subgroup (n =234),the posterior circulation stroke subgroup (n =75) and watershed cerebral infarction or multiple infarction subgroup (n =12).Multivariate logistic regression analysis revealed that older age at initial stroke onset (OR =1.036,95 ％ CI 1.006-1.067,P =0.02) and hyperlipidemia (OR =2.253,95 ％ CI 1.092-4.647,P =0.028) were both the independent risk factors for the recurrent ischemic stroke.Comparing the subgroups,multivariate logistic regression analysis showed that atrial fibrillation (OR =4.217,95％ CI 1.489-11.942,P =0.007) was the independent risk factor for the recurrent ischemic stroke in the posterior circulation territory.Conclusion Aging and hyperlipidemia are possible predictors of recurrent ischemic stroke after the initial ischemic stroke which would be useful for individualized secondary prevention of stroke.

Objective To summarize the successful experience of three cases of heart-lung transplantations performed in our institute.Methods From July 2003 to August 2012,three patients,with diagnosis of end-stage heart-lung diseases,received heart-lung transplantation in our institute.One case was diagnosed as congenital atrial septal defect,Eisenmanger syndrome,NYHA class Ⅳ; one was dilated cardiomyopathy with moderate/severe pulmonary arterial hypertension,NYHA class Ⅲ-Ⅳ,one was diagnosed as double outlet left ventricle (DOLV) with ventricle septal defect and stenosis of pulmonary artery and its left and right branches,NYHA class Ⅲ-Ⅳ.Donor hearts were preserved with UW solution,donor lungs were preserved with Euro-Collin solution in case one and with low potassium dextran containing prostaglandin E1 in the others.Extensive disinfection and strict scrutiny were implemented postoperatively.Immunosuppressive therapy included administration of zenapax or basiliximab preoperatively,methylprednisolone during the operation,and cyclosporine a/tacrolimus + prednisone + mycophenolate postoperatively.Surgical hemostasis is of great importance,as the total pleural effusion reaches 14 640 ml within 31 days postoperatively in case two.Strict postoperative disinfection and isolation were implemented,and management of the respiratory tract was intensified.Therapeutic bronchoscopy was performed frequently for sputum suction.In case two,bronchoscopy was used thirteen times within 40 days after transplantation.Broad-spectrum antibiotics and antifungal antibiotics were used for infection control.Results All three patients were discharged after recovery from operation.Case one died of obstructive bronchitis and lung failure caused by chronic rejection four years and ten months postoperatively.Case two died of sudden cerebrovascular accident 68 days after operation.Case three survives more than one year postoperatively so far and is still alive.Conclusion Proper preservation of the donor heart and lung,perfect surgical hemostasis,strict infection control,frequent application of bronchoscopy and appropriate immunosuppressive management are critical to the success of heart-lung transplantation.

ObjectiveTo study the mechanism of myocardial dielectric property changes in radio frequency during hypothermic preservation and explore myocardial viability evaluative method. Methods Hybrid young pigs (20-30 kg) were used in the experiment. Heart arrest was induced with GIK solution. According to preservative temperature, the animals were divided into three groups: group A (4 ℃),group B (15 ℃) and group C (25 C). The heart was preserved in saline for 12,6 and 4 h respectively. Myocardial dielectric properties and ATP content were tested every 5 and 30 min during hypothermic preservation respectively. The relationship between tanoδm and ATP content was analyzed. ResultsTanδm of three groups was decreased significantly at the beginning, most slightly in group A and most obviously in group C. There was no significant difference in Tanδm between group B and group C with group A at 1 h,but there was obvious difference at 2,3 and 4 h (P＜0. 05,P＜0. 05,P＜0. 01 ). There was correlation between tanδm and ATP in the three groups. ConclusionTanδm in three groups is dropped with preservation time and temperature, and tanδm had a correlation with ATP content. Detection of myocardial dielectric property in radio frequency is a kind of quick, accurate and noninvasive method.

Background and purpose: Platelet to lymphocyte ratio (PLR) is an important factor reflected systematic inflammation. The clinical value of PLR has not been confirmed. The present study was to explore the value of preoperative PLR in predicting clinical stage and prognosis in upper tract urothelial carcinoma. Methods:Patients who underwent surgical therapy with postoperative pathology upper tract urothelial carcinoma without metastasis from Jan. 2007 to Mar. 2012, were collected. Following up was done by telephone and clinic work, 150 vs 1 was taken as the threshold value of PLR, and the association of PLR with tumor stage, whether suffered bladder cancer as comorbidity, recurrent or metastasis, overall survival, tumor lesion, preoperative hematuria, gender and age was analyzed. We further analyzed the association difference of disease free survival (DFS) time and overall survival (OS) time between different PLR groups. Results:Fifty-one cases of UTUC were collected, and the postoperative mean following up time is 21 (9–51) months. Twenty cases recurred or metastasis and 9 cases died. The mean DFS time was 15 (2–51) months,and the mean OS time was 21 (9–51) months. One-factor analysis of variance showed that preoperative PLR was associated with tumor stage, overall survival rate, hematuria and gender, and the P value were 0.028, 0.008, 0.045, 0.036 respectively. High PLR group was intended to be non-organ confined disease, the sensitivity was 57%and the specificity was 74%. Survival analysis by Kaplan-Meier method showed there is no statistical difference in DFS between high and low PLR groups (P=0.155). But OS time in high PLR group was significantly less than that in low PLR group (P=0.006). Cox regression confirmed that only tumor stage is an independent prognostic factor of OS (P=0.029). Conclusion:PLR has potential clinical value in predicting advanced stage disease and Cox regression confirmed that only tumor stage is an independent prognostic factor of OS.
