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 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 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 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 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 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.

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 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.

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.

Objective To analyze prognosic factors for patients with hormone refractory prostate cancer (HRPC) after chemotherapy of docetaxel/mitoxantrone plus prednisone and to explore the relationship between prostate specific antigen (PSA) parameters and prognosis. Methods Data from 68 patients with CRPC after chemotherapy were collected and analyzed retrospectively.The median age of these patients were 65 years old with 28 cases of biopsy Gleason score ＜ 8 and 35 cases of ≥ 8.The median serum PSA at diagnosis,nadir and pre-chemotherapy baseline were 142 ng/ml,0.5 ng/ml and 33.0 ng/ml,respectively.There were 38 patients in docetaxel group and 30 in mitoxantrone group.PSA doubling time ( PSADT),progression free survival (PFS) and overall survival (OS) was calculated.Chi square test was used in analysis of chemotherapy effect and Cox proportional hazards regression model was applied to identify the predictors for PFS and OS.The median value of continuous variable as cutoff point was used to divide patients into two groups to compare.Risk ratio and 95％ confidence interval (CI) was calculated. Results 38 (55.9％)patients experienced effective chemotherapy. The effective rate were 33％ and 74％ for PSADT ＜ 1.6 months and ≥ 1.6 months group,85％ and 49％ for M0 and M1 stage group,and 69％ and 40％ for docetaxel and mitoxantrone group,(P ＜ 0.05).The median PFS was (3.5 ± 0.5) months for all patients,which were (2.7 ±0.4) months and (5.9 ±0.6) months for patients with PSADT ＜ 1.6 months and ≥ 1.6 months group,(5.0 ± 0.6) months and (2.7 ± 0.5 ) months for patients with docetaxel and mitoxantrone group,and (5.7 ± 0.8) months and ( 3.4 ± 0.6) months for patients with Gleason score ＜ 8 and ≥ 8 group (P ＜0.05).26 case died in the end and the median OS was (28.3 ± 2.6) months for these patients,which were (15.7 ± 3.4) months and (31.6 ± 1.2) months for patients with PSADT ＜ 1.6 months and ≥1.6 months group,(29 ± 4.1 ) months and (28 ± 3.2) months for patients with docetaxel and mitoxantrone group,and (28.7 ± 2.6) months and (24.3 ± 5.6) months for patients with Gleason score ＜ 8 and ≥ 8 group (P ＜ 0.05). Conclusions The effective rate of chemotherapy was related with PSADT,chemotherapy strategy and M stage.PSADT,chemotherapy strategy and Gleason score may be independent predictors for patients with HRPC taking chemotherapy.Patients with PSADT ≥ 1.6 months,docetaxel chemotherapy and Gleason score ＜ 8 will have longer PFS and OS.
