Objective To evaluate the effect of detailed disease management model in community management of hyperuricemic patients.Methods One hundred and fifty patients with primary hyperuricemia were randomly divided into detailed management group and conventional group from April to June 2012,patients in two groups were managed by different models for 1 year.The weight,height,biochemical indexes including blood uric acid and serum lipids were measured and a questionnaire survey was conducted with the items of disease awareness score,smoking,drinking,diet,standard treatment,satisfaction of treatment etc.before and after management.Results One hundred and thirty six patients completed the study including 68 in detailed management group and 68 in conventional group.After one year management,the blood uric acid,triglyceride,low density lipoprotein (all P ＜ 0.01) were statistically lower than baseline in detailed management group,while there were no statistical differences of these indexes in conventional group (P ＞ 0.05).The disease awareness score increased from (65.4 ±5.4) to (82.7±4.2) (Z=-10.2,P＜ 0.01),high purine diet rate fell from 47.1％ to 7.4％ (x2 =33.6,P ＜ 0.01),the standard treatment rates increased from 10.3％ to 85.3％ (x2 =76.6,P ＜0.01),treatment satisfaction rate increased from 51.5％ to 88.2％ (x2 =21.8,P ＜0.01) in detailed management group.In detailed management group,the blood uric acid (Z =-7.4,P ＜ 0.01),total cholesterol (Z =-0.01,P ＜ 0.01),triglyceride (Z =-2.4,P ＜ 0.01) and low density lipoprotein (Z =-3.2,P =0.03) and high purine diet rate were lower (x2 =27.1,P ＜ 0.01),the standard treatment rate (x2 =70.6,P ＜ 0.01) and treatment satisfaction rate were higher (x2 =5.6,P =0.02) than those in conventional group after 1 year management.Conclusion Detailed disease management is an applicable and effective model for community management of hyperuricemic patients.

Objective To evaluate the value of photodynamic diagnosis for early detection of bladder cancer using narrow band imaging fluorescence cystoscopy. Methods A total of 28 cases of painless hematuria underwent narrow band imaging(NBI) endoscopy and biopsy. The procedure was as follows: biopsies were taken from lesions that were either fluorescing or nonfluorescing using endoscopy by NBI system) and then TUR was performed on them. Results Of the 28 cases, 79 biopsies were taken. Histopathologic examination showed that 32 of them were of urothelial cell carcinoma. Compared with white light cystoscopy, NBI had a sensitivity of 100% (32/32) ,flat small fluorescence positive lesions were found in peritumoral or other regions, which could not be detected by white light cystoscopy. Conclusion Photodynamic diagnosis using NBI fluorescence cystoscopy is useful for detection of early bladder cancer.

Objective To investigate the correlation between cerebral artery stenosis (MCAS) and mild cognitive impairment (MCI).Methods Continuous selected 636 cases of 50-80 years old inpatients or outpatients who examined by transcranial color Doppler ultrasound (TCD) in April 2012 to April 2013 in our hospital.Keep the mini-mental state examination (MMSE) and clinical dementia rating (CDR) as the evaluation of cognitive function.Results Detected 124 cases of MCAS patients (MCAS group) and 512 cases of non-MCAS patients (non-MCAS group).Forty-four cases MCI were detected in MCAS group with the prevalence rate was 35.5％(44/124),and 114 cases of patients with MCI were detected in non-MCAS group with the prevalence rate was 22.3％ (114/512),the difference was statistically significant (P ＜ 0.05).Single factor analysis showed that there were no significant difference between two groups in waist circumference,hypertension,coronary heart disease,hyperlipidemia,smoking,diastolic blood pressure and total cholesterol,uric acid,fasting glucose,C-reactive protein (P ＞ 0.05); There were significantly different between two groups in age,gender,education level,MCAS,history of diabetes,systolic blood pressure and triglyceride,low density lipoprotein-cholesterol,high-density lipoprotein-cholesterol(P ＜ 0.05).Multiple factors analysis showed that the MCAS (OR =1.899,95％ CI 1.224-2.946),history of diabetes (OR =1.764,95％ CI 1.191-2.612),systolic blood pressure(OR =1.012,95％ CI 1.003-1.022),gender (OR =0.558,95％ CI 0.380-0.821),and age (OR =1.029,95％ CI 1.010-1.049) was the independent risk factor for MCI.Conclusion The MCAS related with MCI occurrence and development.

Objective To summarize the clinical features,neuroimaging findings and pathological characteristics of demyelinating pseudotumors(DPT)of the brain,and to differentiate it from glioma. Methods The clinical features,neuroimaging findings and pathological characteristics of 35 patients with demyelinating pseudotumors of the brain were summarized,and the diagnosis for 18 of them was confirmed by bioscopy.Results Demyelinating pseudotumors affected adults of both sexes.The onset age of patients ranged from 9 to 69 years old.There was no definite antecedent,and the clinical syndromes were atypical. Neuroimaging scans showed multiple lesions in cerebral hemisphere,while the lesion in brain stem and spinal cord was single.The symptom and neuroimaging were not parallel.While with many or large lesions, the symptoms and signs were less.The lesions were not enhanced on CT scan,but appeared round or patch enhancement on MRI scan.Nine patients with DWI all appeared high density.The myelin basic protein was useful for diagnosis.The typical pathological changes were demyelination,perivascular inflammatory infiltration and reactive gliosis.The Creutzfeuldt cells were also found in these patients.The lesions might become small or disappear after treatment,but could not serve as the criterion to exclude brain neoplasm. Conclusions DPT is a distinct demyelination disease entity,which is confusable with brain neoplasm.It is difficult to distinguish DPT from brain neoplasm with the clinical features and conventional neuroimaging scan.But DWI scan is useful.The pathological changes accord with demyelination,and Creutzfeuldt cells are also found.It is important to apply corticosteroid treatment or biopsy rather than being anxious to excise the lesions.

Objective to investigate the level of platelet leukocyte aggregates in patients with acute cerebral infarction and their short term prognosis.Methods 105 patients with acute cerebral infarction onset within 24 hours were selected continuously,then platelet leukocyte aggregates including neutrophil aggregates (PNA) and platelet monocyte aggregates (PMA) and platelet lymphocyte aggregates (PlyA) were detected by flow cytometry within 24 hours of admission and the incidence of 14 days.modified Rankin Scale(mRS) was performed at 14 days of onset,as a prognostic indicator,and the mRS score was good at 3.The score >3 mRS was divided into poor prognosis.The level of platelet leukocyte aggregates was detected in 50 healthy subjects.Results (1) The platelet leukocyte aggregates in patients with acute cerebral infarction group were significantly higher than that of the healthy group,which was statistically significant (P<0.05).(2)MRs score <3 group and mRS score >3 score comparison,the difference of white blood cell aggregates was statistically significant(P<0.05).Conclusion leukocyte aggregates could be used as an index of short-term prognosis in patients with acute cerebral infarction.

Objective To assess the significance of urethral sphincter electromyography (US-EMG) and external anal sphincter electromyography (EAS-EMG) for the diagnosis of multiple system atrophy (MSA).Methods US-EMG and EAS-EMG were performed in 9 patients who were diagnosed as MSA.Duration,motor unit action potentials amplitude,polyphasicity,as well as recruited pattern and amplitude during powerful contraction were recorded and analyzed.Results Among 9 patients who were diagnosed as MSA,7 cases showed neural injury by both US-EMG and EAS-EMG.There was significant difference of electromyographic findings between US-EMG group and EAS-EMG group (average volatility (μV):1063.44 ±499.92 vs 634.89 ±265.07; polyphasic wave:0(0,20％ ) vs 57％ (28％,63％ ) ; t =2.567,P=0.033;t =2.833,P=0.012).Conclusions Although US-EMG may be difficult to perform,US-EMG may have the same specificity as EAS-EMG for the diagnosis of MSA,especially for the diagnosis of MSA patients only with urination disorders,who are involved in Onuf neclear according to some of the abnormal indexes.

Objective To examine the application effect of intelligent simulator(SimMan) in comprehensive skill training among doctors and nurses.Methods Totally 168 doctors and nurses were chosen as the training object,6 people (4 doctors and 2 nurses) formed a work team.Comprehensive training course was in accordance with 2010 American Heart Association guidelines for cardiopulmonary resuscitation and emergency cardiovascular care science.Real clinical situation was designed by using the third generation SimMan of Norway laerdal company.Trainees were administered two tests before and after training,in which there were two parts containing specialized operation ability and non-technical ability.Overall qualification rate,average mark and treatment time of qualified teams were compared before and after the training.SPSS 16.0 software was used to analyze the data and P ＜0.05 signifies statistically significance.Results Overall qualification rate,average mark and treatment time of qualified teams were 71.43％,(84.70 ± 3.15),and (449.25 ± 77.0) s respectively before training while 100％,(93.55 ± 3.86) and (323.71 ± 42.26) s after training.There were significant differences in results of two groups before and after training (P =0.002,0.000,0.000).Conclusions Application of the third generation intelligent simulator (SimMan) in comprehensive training will obviously improve training effectiveness and cultivate the non-technical ability.

Objective To investigate the correlation of the middle cerebral artery stenosis (MCAS) and the mild cognitive function impairment (MCI),and the clinical efficacy of statins in patients with MCI. Methods Six hundred and thirty-six patientse,who received transcranial color doppler ultrasound (TCD)assay, were enrolled in our hospital hospitalization or outpatients. The simple mental state examination (MMSE) and clinical dementia rating scale (CDR) were used as cognitive function assessment indexes. Forty-four cases of MCI with MCAS and 58 cases of MCI with NMCAS were used as the treatment group , who received the atorvastatin 20 mg every day , 56 cases of MCI with NMCAS were used as the control group , who only received the routine and basic diseases treatment. One yearlater,we determined the changes of MMSE and CDRagain. Results We detected 124 patients with MCAS, 512 patients with NMCAS, and 44 cases of MCAS patients with MCI, the prevalence was 35.5%,114 cases of NMCAS in patients with MCI, with the prevalence of 22.3%, the prevalence between the two groups was statistically different. One year later, the patients in the treatment group, MMSE score was improved, the score of MCI of the MCAS group improved more significantly. Conclusion The middle cerebral artery stenosis correlated with the occurrence of MCI. Atorvastatin could improve cognitive function in patients with MCI, especially for MCI which was caused by middle cerebral artery stenosis.

Objective To assess the effect of continuous renal-replacement therapy (CRRT) dose on the outcome of acute renal failure (ARF) patients with meta-analysis of randomized controlled trials (RCTs). Methods Studies were identified by systematic search of peer-reviewed publications in Medline, EMBASE and Cochrane library database through June 2010. All the RCTs that compared the incidence of clinical outcome such as mortality, need for chronic dialysis between standard and low dose CRRT were eligible. The pooled relative risk (RR) for clinical outcome was compiled using a random-effects model. Heterogeneity was evaluated by means of subgroup and sensitivity analysis. Results Six eligible studies were identified. By meta-analysis, standard dose CRRT was associated with non-significant 13% mortality risk reduction (RR 0.87, 95%CI 0.70-1.07, P=0.19)and 13% composite outcome risk reduction of chronic dialysis dependence and mortality (RR 0.87, 95%CI 0.69-1.09, P=0.21), but the trend toward increased chronic dialysis dependence risk among survivors (RR 1.43, 95%CI 0.94-2.18, P=0.09). The overall test for heterogeneity among cohort studies was significant (P=0.001, I2=76.2%). The risk of mortality was modality was significantly lower in some studies of which delivered dose was moer than 35 ml·kg-1·min-1,modality was continuous venous-venous hemofiltration (CVVH) and major cause was non-sepsis treated with standard dose CRRT. Conclusions Standard dose CRRT in patients with ARF does not improve survival, renal recovery and composite outcome, but decreases mortality in important subgroups including those with higher delivered dose, CVVH and non-sepsis.

Objective To explore the clinical features, imaging and their diagnosis vaule of Baló's concentric sclerosis (BCS). Methods The clinical manifestation, laboratory examination, neuroimaging characteristics, pathology and follow-up of 12 (2 outpatients and 10 inpatients) cases of BCS were analyzed retrospectively. Results The onset age of 12 patients (male 4, female 8) ranged from 8 to 54 years old (mean 36.8 years). Unconcerned and slowness response were common in the disease onset (7 cases).Other symptoms and signs such as hypophrenia ( 10 cases), limitation of limb or hand movement (8 cases),urinary and fecal incontinence (7 cases), hypo-myodynamia (7 cases), positive pyramidal sign (6 cases)were not rare in course of disease. Eight cases underwent the examination of cerebrospinal fluid myelin basic protein, which increased in 7 cases. Demyelinating change and perivascular inflammatory infiltration were shown in 6 brain biopsies. The involvements of multi-lesions were found in 11 cases. Four patients underwent CT scanning and all the cases showed with hypodense lesions and couldn' t be enhanced. On MRI, all cases appeared round or round-like in shape. Enhanced lesions showed ring-like or half-ting-like shape (8 cases) and concentric ring (3 cases). It's easy to be misdiagnosed as brain tumor (8 cases).Conclusions BCS is a kind of demyelinating disease of subacute or chronic onset accompanied with cognitive disorder being the most common initiating symptoms. It's prone to be misdiagnosed. Diagnosis depends on MRI and corticosteroid treatment is effective. BCS has a good prognosis and presents with benign clinical course.
