Lower urinary tract symptoms in Parkinson's disease and multiple system atrophy / 中华老年医学杂志

Parkinson's disease(PD)and multiple system atrophy(MSA)are two common Parkinsonian syndromes with overlapping clinical manifestations, and clinical differential diagnosis is difficult.Lower urinary tract symptoms are one of the common non-motor symptoms of the two diseases.The incidence of lower urinary tract symptoms in MSA is higher, the onset is earlier, and the micturition period is more prominent.The urinary dysfunction in patients with PD is mainly caused by the central mechanism, leading to overactive bladder.MSA has more extensive lesions with both central and peripheral involvement, leading to overactive bladder and severe voiding dysfunction.Urodynamics can be used to evaluate bladder and urethral function.MSA has more prominent weak detrusor activity, residual urine volume, and early changes of urethral sphincter.The treatment of lower urinary tract symptoms in patients with PD is mainly based on anticholinergic drugs to improve overactive bladder, while in MSA patients with increased residual urine volume, intermittent catheterization is the main method to improve lower urinary tract symptoms.This article reviewed the epidemiology, pathological mechanism, urodynamics and treatment of lower urinary tract symptoms of the two diseases, so as to assist in their differential diagnosis and treatment.

Clinical characteristics of subjective cognitive decline in patients with Parkinson′s disease and its relationship with affective symptoms: a preliminary study / 中华神经科杂志

Objective:To investigate the characteristics and clinical related factors of Parkinson′s disease (PD) patients with subjective cognitive decline (SCD).Methods:Ninety-nine PD patients with normal cognitive function enrolled in Beijing Hospital from January to December 2018 were collected for the study. Patients with PD were divided into groups with ( n=57) and without ( n=42) SCD using the first question in Part 1 of the Unified Parkinson′s Disease Rating Scale (UPDRS). All patients were assessed by Montreal Cognitive Assessment (MoCA), modified Hoehn-Yahr grading, UPDRS, Hamilton Rating Scale for Depression (HAMD), Hamilton Rating Scale for Anxiety (HAMA), Parkinson′s Disease Sleep Scale, Ability of Daily Living Scale and 39-item Parkinson′s Disease Questionnaire (PDQ-39). Levodopa equivalent dose conversion was performed for patients taking anti-PD drugs. Patients′ self-reported years of formal education were collected. Results:The proportion of PD with SCD in this group was 57.58% (57/99). There were statistically significant differences in MoCA [28.00 (27.00, 29.00) vs 28.00 (27.00, 29.00) ,Z=-2.28, P=0.023], HAMD [6.00 (5.00, 8.50) vs 5.00 (2.00, 8.00), Z=-2.23, P=0.026], HAMA [7.00 (6.00, 11.00) vs 6.00 (3.00, 8.25) , Z=-2.70, P=0.007], PDQ-39-emotional health [2.00 (0, 5.00) vs 1.00 (0, 3.00), Z=-2.03, P=0.042] and PDQ-39-cognitive scores [4.00 (2.00, 5.00) vs 2.00 (0, 4.00), Z=-3.42, P=0.001] between PD with and without SCD groups. SCD was correlated with MoCA ( r=-0.23, P=0.022), HAMD ( r=0.23, P=0.025) and HAMA ( r=0.27, P=0.006) scores to varying degrees. When controlling for HAMD and HAMA scores, the correlation between SCD and MoCA scores ( r′=-0.18, P=0.084) was no longer existed. Conclusions:SCD is common in PD patients with normal cognitive function and is associated with poorer cognitive performance and more severe symptoms of depression and anxiety. In this group of patients, the relationship between SCD and affective symptoms may be greater than that of objective overall cognitive function, which is worthy of further studies.

Clinical features of corticobasal syndrome and associated chronic pain:analysis of 8 cases / 中华全科医师杂志

Objective:To investigate the clinical features and associated chronic pain in corticobasal syndrome (CBS).Methods:Clinical data of 8 patients diagnosed as probable CBS or possible CBS admitted to Beijing Hospital during January 2010 to June 2020 were retrospectively analyzed. The clinical information included sex, age, course of disease, chief complaint, neurological examination, blood biochemistry, tumor marker, infection and other laboratory tests; the neuropsychological evaluation included Mini-Mental State Examination (MMSE) scale and Hamilton Depression Scale (HAMD); the imaging studies included cranial magnetic resonance imaging (MRI) and/or 18F-Fluorodeoxyglucose positron emission tomography ( 18F-FDG PET). Results:The main clinical manifestations were asymmetrical movement disorders, including rigidity, tremor, myoclonus and abnormalities in posture and gait. Patients showed poor response to levodopa treatment. Among 8 patients, 7 had apraxia, 5 patients had alien hand, and 5 patients had various degrees of cognitive dysfunction. The cranial MRI demonstrated mild cerebral atrophy which was slightly more severe in the contralateral side of the initially affected limb in 7 of the 8 patients. The 18F-FDG PET scan revealed asymmetric decreased metabolism in the frontal, parietal, temporal, and occipital lobe, as well as in basal ganglia, which was more severe in the contralateral side of the initially affected limb in 5 of the 8 patients. Six of the 8 patients were associated with pain, including dystonic pain in 3 patients, neuropathic pain in 1 patient, musculoskeletal pain in 1 patient, and unexplained pain in 1 patient. Pain was the onset symptom in 1 patient and pain was relieved by taking levodopa in another patient. Conclusions:CBS is characterized by asymmetric dyskinesia and cognitive impairment, and often associated with apraxia, cortical sensory deficits, and alien limb. The MRI and PET are helpful for CBS diagnosis. Pain may be one of the common non-motor symptoms in CBS.

A clinical study of myocardial viability in predicting the improvement of cardiac function after coronary artery bypass grafting in patients with ischemic heart failure / 中国胸心血管外科临床杂志

@#Objective    To explore the predictive value of myocardial vitality in the improvement of cardiac function after coronary artery bypass grafting (CABG) in patients with ischemic heart failure. Methods    From December 8, 2015 to November 12, 2018, 46 patients with ischemic heart failure who underwent CABG operation alone were collected retrospectively. There were 41 males and 5 females with an average age of 60.4±8.0 years. The myocardial vitality and number of different types of myocardium were measured. The clinical data of patients in the left ventricular ejection fraction (LVEF) improvement group (≥5%) and non-improvement group (<5%) were compared and analyzed. The  correlation between each index and LVEF improvement was analyzed by logistic multivariate regression analysis, and the boundary value of hibernating myocardium between LVEF improvement and non-improvement was obtained by receiver operating characteristic (ROC) curve. Results    There were significant differences in the number of hibernating myocardium (15.0%±12.3% vs. 4.3%±4.5%, P=0.000), the number of normal myocardium (74.7%±13.7% vs. 82.4%±8.6%, P=0.027), and cardiac function classification (NYHA) development (−0.7±0.7 vs. −0.3±0.5, P=0.047) between the two groups, but there was no significant difference in other indexes between the two groups (P>0.05). Logistic regression analysis showed that the number of hibernating myocardium was an independent factor affecting the improvement of LVEF after CABG in patients with ischemic heart failure (OR=1.366, 95%CI 1.033-1.807, P=0.029). The ROC curve showed that the threshold value, sensitivity and specificity of hibernating myocardium were 15.0%, 43.8% and 100.0%, respectively. Conclusion    The percentage of hibernating myocardium to left ventricular wall area ≥15.0% can accurately predict the improvement of LVEF in patients with ischemic heart failure after CABG. Preoperative myocardial vitality assessment has important diagnostic value in predicting the improvement of cardiac function in patients with ischemic heart failure after simple CABG.

Clinical value of mean platelet volume/platelet count ratio in predicting short-term prognosis of elderly patients with acute exacerbation of chronic obstructive pulmonary disease / 中华老年医学杂志

Objective:To explore the clinical value of mean platelet volume/platelet count ratio(MPV/PLT)in predicting short-term prognosis of elderly patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods:A total of 226 elderly patients with AECOPD admitted to our hospital from January 2017 to January 2019 were retrospectively enrolled as research subjects.All cases were divided into the survival group(n=175)and the death group(n=51), based on prognosis 28-day after admission.General data and laboratory test results were compared between the two groups.The relevant factors for death were analyzed by the Logistic regression equation.The receiver operating characteristic(ROC)curve was used to evaluate the prognostic value of MPV/PLT, and the Kaplan-Meier survival curve was drawn according to the cut-off.Methods:Compared with the survival group, Acute Physiology and Chronic Health Status Evaluation(APACHEⅡ)score, levels of procalcitonin(PCT), high-sensitivity C-reactive protein(hs-CRP), creatinine, neutrophil count(NEU), lymphocyte count(LYM)and MPV were elevated, and levels of albumin and PLT decreased in the death group( P<0.05). Hospital stay lengths and costs were higher in the death group than in the survival group( P<0.05). The level of MPV/PLT was higher in the death group than in the survival group(0.065±0.016 vs.0.054±0.013, t=5.036, P<0.01). Multivariate Logistic regression showed that MPV/PLT was an independent risk factor for recent death( OR=2.331, 95% CI: 1.772-8.224, P<0.01). ROC curve analysis showed that the area under the curve(AUC)of MPV/PLT was 0.829, the sensitivity was 83.41%, the specificity was 82.80%, and the cut-off was 0.061.Optimal cut-off value analysis showed that APACHEⅡ score, PCT and hs-CRP levels and mortality were higher in patients with MPV/PLT≥0.061 than in patients with MPV/PLT<0.061( P<0.05). The Kaplan Meier survival curve showed that the cumulative survival rate was lower in those with MPV/PLT≥0.061 than in those with MPV/PLT<0.061( Log- rank=6.323, P<0.05). Conclusions:The increase of MPV/PLT may be an independent risk factor for recent death in elderly patients with AECOPD and has good clinical value in predicting poor prognosis.

Establishment of an acute pericardial effusion animal model guided by ultrasound / 中华超声影像学杂志

Objective To explore the feasibility of establishing an acute pericardial effusion animal model guided by ultrasound. Methods Six experimental pigs were anesthetized. A PTC needle was injected and guided to the right ventricular anterior wall under real-time high frequency ultrasound,40 ml and 80 ml normal saline were respectively infused into the pericardial cavity within 5 minutes. Ultrasonography and pathologic examination were applied to confirm this porcine model. The amount of the fluid was estimated by ultrasound at 1 hour and 8 hours after infusion. Results With ultrasound guidance,the PTC needle smoothly entered the pericardial cavity and the saline was successfully injected. The fluid dispersed from local to the entire pericardial cavity. Pericardial effusion last within 8 hours and no significant change of the fluid amount was found (all P ＞0.05). This acute pericardial effusion model was successfully established with a rate of 100%. Conclusions It is feasible to establish an animal model of acute pericardial effusion under the guidance of ultrasound. This method is safe,rapid and effective. It can provide a suitable animal model for the study of acute pericardial effusion.

Survey on sleep disorders in patients with Parkinson disease / 中华全科医师杂志

Objective@#To survey the prevalence and distribution of sleep disorders in patients with Parkinson disease (PD) and to analyze the influencing factors.@*Methods@#The prevalence and distribution of sleep disorders were surveyed with Parkinson Disease Sleep Scale (PDSS) among 206 PD patients. The association of sleep disorders with age, course of disease, cognitive function, motor function, depression, and the equivalent dose of levodopa (LED) was analyzed.@*Results@#The overall PDSS score in 206 patients was (116.9±21.4). The three most frequent items of sleep disorders were the overall sleep quality(181/206, 87.9%), difficulty in maintaining sleep(160/206, 77.7%)and nocturnal enuresis(151/206, 73.3%); the three least frequent items were early awaking(87/206, 42.2%), urinary incontinence(56/206, 27.2%)and hallucination(44/206, 21.4%). The three items with the lowest average scores were nocturnal enuresis(6.9±3.1), difficulty in maintaining of sleep(7.1±2.7)and overall sleep quality(7.1±2.0); three items with the highest average scores were audiovisual illusion(9.3±1.8), incontinence caused by motion disability(9.0±2.1) and early awaking with upper and lower limb pain(8.7±2.1). PD patients were divided into group 1 [Hoehn-Yahr(H&Y) stage 1.0-1.5], group 2 (H&Y stage 2.0-2.5) and group 3 (H&Y stage 3.0-4.0). One-way analysis of variance or non-parametric test showed that there were significant differences in the course of disease(F=21.91, P=0.00), total score and the subscale scores of Unified Parkinson Disease Rating Scale(UPDRS, UPDRS Ⅰ-Ⅳ) (F=90.67, χ2=12.86, F=31.20, F=60.17, χ2=24.01, all P<0.01), the Hamilton Rating Scale for Depression(HAMD) scores (χ2=11.06, P=0.00), LED (F=14.93, P=0.00) and Minimum Mental State Examination(MMSE) scores (χ2=9.81, P=0.01) among three groups. There was no significant difference in age and PDSS scores among three groups. The results showed that there were significant differences in terms of restless state and nocturnal dysphoria (F=5.12, P=0.01; F=3.27, P=0.04) between group 1 and group 3. The linear regression analysis showed that the HAMD and the LED scores had the greatest influence on PDSS score (R2=0.142, 0.196).@*Conclusion@#PD patients have a variety of sleep symptoms. The treatment of large doses of dopamine and depression contribute to the occurrence of PD sleep disorders.

Characteristics and correlative factors of musical emotion recognition in patients with Parkinson's disease / 中华神经科杂志

Objective To investigate emotion recognition in music in patients with idiopathic Parkinson's disease (PD),and to further explore its relationship with executive function and related factors.Methods Twenty-four PD patients enrolled from the Department of Neurology,Beijing Hospital between January and June 2014 and 24 matched healthy controls were tested using 24 musical excerpts that expressed happiness,sadness,fear or anger.The two groups were tested for executive function using a simplified trail making test and a clock drawing test.All the patients were rated on the Hoehn-Yahr stage,the Unified Parkinson' s Disease Rating Scale (UPDRS) Ⅲ,the Hamilton Rating Scale for Anxiety (HAMA) and the Hamilton Rating Scale for Depression (HAMD).Results In trail making test,PD patients worked slower ((51.58 ±33.14) s) than controls ((34.46 ± 19.64) s) (t =2.178,P =0.036).PD patients got more errors (0 (QL =0,QU =2.5)) than controls (0 (QL =0,QU =0);Z=-2.372,P =0.018).In clock drawing test,PD patients got lower score (2.63 ±0.65) than controls (2.96 ±0.20)(t =-2.407,P =0.023).The difference between two groups was not statistically significant in the recognition of happy,sad,fear or anger music (all P ＞ 0.05).In PD group,the scores of the recognition of happy,sad music and the total score of musical emotion recognition were associated with the time of trail making test (r =-0.560,-0.572,-0.530,P =0.004,0.003,0.008),while not related to age,disease duration,education duration,the scores of Minimum Mental State Examination,the scores of UPDRS Ⅲ,Hoehn-Yahr stage,the scores of HAMA,the scores of HAMD,LDE,the scores of clock drawing test or musical background (all P ＞ 0.05).Conclusions PD patients are not impaired in emotion recognition in music in this study.The relationship between musical emotion recognition and executive function is unclear.

Effect of hydrogen sulfide on hepatic lipid accumulation in obese mice / 中国药理学通报

Aim To investigate the effect of hydrogen sulfide on hepatic lipid accumulation in obese mice. Methods C57 BL/6 J mice were randomly divided into control group, model group, and NaHS group. The mice of the control group were fed with normal diet. The mice of the model group and the NaHS group were fed with high-fat diet. From the thirteenth week, the mice of NaHS group were injected intraperitoneally with NaHS (H2S donor) in a dose of 50 μmol·kg-1 per day for 4 weeks and the mice of the model group were injected with the same volume of saline. All mice were sacrificed at the end of the 16th week. The tis-sues of liver were homogenized and centrifugated. The supernatants were used for the determination of triglyc-eride and cholesterol in liver. The morphology of liver was tested by H&E staining. Liver lipid accumulation was determined by oil red staining. Total RNA was ex-tracted from frozen tissue of liver. PCR was used to de-tect CPT-1 , FAS gene expression and ELISA method was used to detect CPT-1,FAS activity in mice liver. Results The body weight of the mice from NaHS group and model group was bigger than that of the mice from control group. Compared with the model group, the body weight of the mice from NaHS group was less;the content of triglyceride and cholesterol in liver was lower; the degree of liver tissue pathological changes and lipid accumulation were alleviated; CPT-1 expres-sion and activity were increased; FAS expression and activity were decreased. Conclusions These data in-dicate that hydrogen sulfide can reduce the lipid con-tent of liver tissue in obese mice and alleviate fatty liv-er. The mechanism may be associated with the in-creased expression of CPT-1 and the decreased expres-sion of FAS in liver.

Intraoperative high-field magnetic resonance imaging combined with functional neuronavigation in resection of low-grade temporal lobe tumors involving optic radiation / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical value of high-field-strength intraoperative magnetic resonance imaging (iMRI) combined with optic radiation neuro-navigation for the resection of temporal lobe low-grade gliomas.</p><p><b>METHODS</b>From April 2009 to September 2013, 65 patients with temporal lobe low-grade gliomas (WHO grade II) involving optic radiation were operated with iMRI and functional neuro-navigation. Diffusion tensor imaging (DTI) based fiber tracking was used to delineate optic radiation. The reconstructed optic radiations were integrated into a navigation system, in order to achieve intraoperative microscopic-based functional neuro-navigation. iMRI was used to update the images for both optic radiations and residual tumors. Volumetric analyses were performed using 3D Slicer for pre- and intra-operative tumor volumes in all cases. All patients were evaluated for visual field deficits preoperatively and postoperatively. The Student t test was used to evaluate the average rate of extent of resection between groups. Spearman rank correlation analysis was used to assess correlations between predictors and epilepsy prognosis.</p><p><b>RESULTS</b>Preoperative tumor volumes were (78±40) cm3. In 29 cases, iMRI scan detected residual tumor that could be further resected, and extent of resection were increased from 76.2% to 92.7% (t=7.314, P<0.01). In 19 cases (29.2%), gross total resection was accomplished, and iMRI contributed directly to 8 of these cases. Postsurgical follow-up period varied from 13 months to 59 months, mean (33±13) months. Tumor progression were observed in 3 patients, newly developed or deteriorated visual field defects occurred in 4 patients (6.2%). For patients with pre-operative seizures, Engel Class I were achieved for 89.7% of them. Spearman rank correlation analysis revealed that seizure outcome (Engel Class) was related to increased excision of ratio (r=-0.452, P=0.004, 95% CI: -0.636--0.261) and larger tumors (r=0.391, P=0.014, 95% CI: 0.178-0.484).</p><p><b>CONCLUSIONS</b>With iMRI and functional neuro-navigation, the optic radiation can be accurately located, while extent of resection can be evaluated intra-operatively. This technique is safe and helpful for preservation of visual field for the resection of temporal lobe low-grade gliomas involving optic radiation.</p>

Familial hemiplegic migraine complicated with diffuse cerebral edema: report of one case and review of literature / 中华全科医师杂志

Objective To analyze clinical characteristics of migraine complicated with cerebral edema.Methods We first time reported a case of familiar hemiplegic migraine complicated with diffuse cerebral edema in China,another 19 cases of migraine complicated with cerebral edema were reported in literature.The clinical characteristics of these 20 cases were analyzed.Results In 20 cases,the male:female ratio was 1.2∶ 1,the mean age of onset was (16.0 ± 10.2) years.All 20 cases were complicated with cerebral edema,among whom 8 (40％) were familiar hemiplegic migraine,8 (40％) were sporadic hemiplegic migraine,4 (20％) were migraine with aura.Common neurological symptoms and signs included paralysis (75％),aphasia (65％),disturbance of consciousness (60％),disordered vision (40％),Paresthesia (35％).Eleven cases (55％) had permanent neurological deficit.Conclusions The clinical manifestations of migraine with cerebral edema are complicated,the neurological disturbance is severe and usually has a long duration.The early diagnosis and treatment is beneficial,and preventive treatment in intermittent period is recommended.

Automated proton magnetic resonance spectroscopy imaging guided frameless stereotactic biopsy of intracranial lesions / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the feasibility, reliability and accuracy of the automated magnetic resonance spectroscopy ((1)H-MRS) guided frameless brain biopsy with intraoperative magnetic resonance imaging (iMRI).</p><p><b>METHODS</b>Between July 2011 and July 2013, a consecutive series of 93 patients were prospectively enrolled. All the patients had intracranial lesions which need biopsy to confirm the diagnosis. Among them, 48 patients were male, 45 patients were female. Their age range from 7 years to 76 years, the median age was 47 years. All patients underwent MRS examination. With MRS automatic fusion technique, the metabolic images were integrated into a standard navigation system (Vario Guide) to guide frameless biopsy. High-field iMRI (1.5 T) was used for target inspection, brain shift correction, and intra-operative exclusion of intra-cerebral hemorrhage and other complications.</p><p><b>RESULTS</b>For all the 93 patients, (1)H-MRS based metabolic images could be automatically integrated into a standard navigation system and average fusion procedure could be taken 5 minutes 6 seconds. For (1)H-MRS guided stereotactic biopsy of intracranial lesions, the diagnosis yield rate was 94.6% (88/93). Four cases did not get a clear pathological diagnosis, while 1 case did not match the pathological diagnosis result which obtained by following craniotomy. Technical related complication rate was 2.2% (2 cases, intra-cerebral hemorrhage), which were intra-operatively depicted with iMRI, and managed properly. Among them, 1 case with small volume (5 ml) intracerebral hematoma fully recovered 10 days after surgery without second surgical intervention. One case with large volume intracerebral hematoma (32 ml) was depicted with iMRI, followed by craniotomy and hematoma evacuation in the same session. This case had no new or worsened neurologic deficit post-operatively.</p><p><b>CONCLUSIONS</b>(1)H-MRS based metabolic imaging can be automatically integrated into a standard navigation system and used for frameless brain biopsy. The target can be selected according to the metabolic status of the lesion. Hence, the target can be more accurate. And the pathological diagnosis yield rate is higher. With iMRI, the method is safe, and has high clinical efficacy.</p>
