Objective To observe the features of the full field electroretinogram (FF-ERG) in type 1 diabetes (T1D) children without diabetic retinopathy (DR).Methods Retrospective case study.Forty-one T1D children and 25 age-matched normal controls underwent a complete ophthalmic examination,including best-corrected visual acuity,refraction,intraocular pressure,slit lamp,fundus photography,indirect ophthalmoscopy,and spectral domain optical coherence tomography to exclude DR.All FF-ERG tests were performed by an experienced technician.The ERG series includes six protocols:dark-adapted 0.01 ERG (r-b 0.01);dark-adapted 3 ERG (mix-a 3.0,mix-b 3.0);dark-adapted 10 ERG (mix-a 10.0,mix-b 10.0);dark-adapted oscillatory potentials (OPS);light-adapted 3 ERG (c-a 3.0,c-b 3.0);light-adapted 30 Hz flicker (30 Hz FP) ERG.To compare the amplitudes and implicit times of the FF-ERG between the T1D and control group children.Results Compared with the control subjects,the FF-ERG amplitudes decreased and the implicit times increased in T1D.Except for r-b 0.01 (t =-0.228,P＞0.05),the amplitudes of other FF-ERGs were all significantly attenuated (t =-1.664,-3.645,-4.324,-6.123,-5.846,-12.9,-14.4,-5.23;P＜0.05) in T1D children.The implicit times of mix-b 3.0,mix-b 10.0,c-b 3.0 and OP2 significantly increased (t=5.242,2.879,5.378,3.506;P＜0.05).The implicit times of r-b 0.01,mix-a 3.0,mix-a 10.0,c-a 3.0 and 30Hz FP changes were not significantly (t=2.331,1.677,0.557,0.84,0.064;P ＞ 0.05).Conclusion The FF-ERG amplitudes decreased and implicit times increased in T1D children compared with the control normal subjects.

Objective To discuss the efficacy and safety of covered Cheatham-Platinum stent (CCPS) implantation in treating coarctation of the aorta (CoA).Methods The clinical data of 11 patients with CoA who had received CCPS implantation were retrospectively analyzed.Results Successful implantation of single CCPS was accomplished in all 11 patients.After the implantation,the diameter of coarctation site was immediately dilated from preoperative (4.76+0.89) mm to postoperative (12.86+0.90) mm (t=24.86,P＜0.001),and the average systolic blood pressure difference across the coarctation was immediately reduced from preoperative (38.55+10.02) mmHg to postoperative (9.82+6.60) mmHg,the difference was statistically significant (t=10.8,P＜0.001).The patients were followed up for 3-79 months,with a mean of (31.91±27.58) months.The clinical symptoms were relieved in all patients and the activity tolerance was obviously improved.No complications such as endoleak,acute injury of aortic wall,re-coarctation or re-stenosis,vascular injury of puncture site,or death occurred in all patients.Conclusion For the treatment of CoA,implantation of CCPS has excellent short-term and mid-term effect,meanwhile,this technique can effectively avoid complications such as aortic wall iniurv.(J Intervent Radiol.2017.26:211-214)

Objective To explore the correlated factors and clinical features of cognitive impariment in parkinson's disease (PD).Methods A total of 419 patients with PD were collected from Xiangya Hospital of Centre-South University during Mar 1st,2017 to Nov 30th,2017.The cognitive functions of patients were assessed with the Mini-Mental State Examination (MMSE),and the basic information and the motor symptoms of 419 PD patients were selected at the same time.The PD patients were classified into three groups according to the MMSE score:PD with no cognitive impairment (PD-NC),mild cognitive impairment in PD (PD-MCI),and Dementia in PD (PD-D).The data were analyzed by SPSS 20.0.Results There were 156 patients with PD-MCI (37.2％) and 64 patients with PD-D (15.3％).The difference of sex and disease duration among three groups were not statistically significant (P ＞ 0.05).The significant difference was found among PD-D,PD-MCI,and PD-NC groups in age of onset,age,educational attainment,Unified Parkinson's disease Rating Scale (UPDRS)-Ⅱ score,UPDRS-Ⅲ score and Hoehn-Yahr stage (P ＜ 0.05).There were significant differences among three groups in MMSE score and its items (P ＜ 0.01).Logistics regression analysis found that the age of onset,educational attainment,and Hoehn-Yahr stage were the risk factors of cognitive impairment in PD patients (P ＜ 0.05).Conclusions Cognitive impairment is common in PD patients,and it is relevant to the age of onset,educational attainment and the severity of illness of PD patients.

Objective To explore the status of emotional-social loneliness including emotional isolation,social isolation,emotional and social loneliness in patients with acute cerebral infraction,and to analyze the related factors.Methods A total of 122 patients with acute cerebral infraction admitted to the neurology department of 5 third-grade class-A hospitals from Jan.2017 to Oct.2017 were enrolled.Data was collected by self-reported questionnaires including patients' general data and the emotional-social loneliness questionnaire data.Results Among 122 patients with acute cerebral infraction,emotional isolation,social isolation,emotional loneliness and social loneliness were found in 48 cases(39.3％),60 cases(49.2％),40 cases(32.8％)and 36 cases(29.5％),respectively.The total average score for emotional isolation,social isolation,emotional loneliness and social loneliness were 8.3 ± 5.2,8.6 ± 5.1,7.5 ± 6.1,and 7.4 ± 5.5,respectively.The scores for emotional-social loneliness were associated with education level,monthly family income,occupations and the emotion state before disease,and were not associated with gender,marriage status and stroke history.Conclusions The prevalence of emotional-social loneliness is high in patients with acute cerebral infraction.Especially careful attention should be paid to patients with higher education level and retired with monthly family income ≥5 000 RMB.

Parkinson's disease is a common neurodegenerative disease among elders.Except for the motor symptoms of Parkinson's disease,it usually accompanies with a number of non-motor symptoms,such as constipation,sleep disorder and depression,and also some other comorbidities,such as diabetes,coronary heart disease,osteoporosis,etc.Comorbidities of Parkinson's disease usually affect the life quality,disability and mortality of patients,and increase the risk of polypharmacy and poor prognosis.Therefore,management of comorbidities of Parkinson's disease is critical for individual treatment of Parkinson's disease.This review will analyze and discuss the common comorbidities of Parkinson's disease.

Mycoplasma pneumoniae pneumonia (MPP) complicated with cerebral venous sinus thrombosis (CVST) is rare.We retrospectively analyzed the clinical data of two patients with refractory mycoplasma pneumoniae pneumonia (RMPP) complicated with CVST who were hospitalized in Xi′an children′s Hospital from December 2018 to April 2019, inquired the relevant literature, analyzed the clinical diagnosis and treatment characteristics, and discussed the diagnosis and treatment measures of RMPP complicated with CVST.Two cases were 6-year-old girls with fever and cough as the main symptoms.After physical examination, the respiratory sounds of the affected lung decreased, and the sounds of phlegm and dampness could be heard in both lungs.Mycoplasma pneumoniae (MP) antibody and RNA were positive.Chest CT showed lobar pneumonia with a large number of pleural effusion.The effect of macrolide antibiotics anti infection treatment was not good.Headache symptoms occurred during the course of the disease, and serum D-dimer increased significantly.Brain MRI showed CVST, including 1 case with lower extremity pain, and B-ultrasound showed right lower extremity arterial embolism.After anti infection, thrombectomy, anticoagulation and symptomatic treatment, 2 cases were discharged.When children with MPP, especially those with RMPP, have extracranial thrombosis and/or neurological symptoms, accompanied by elevated serum D-dimer, the possibility of CVST should be considered, and brain MRI examination should be performed in time to confirm and actively treat, which can reduce or avoid the occurrence of sequelae.Thrombosis may be related to excessive inflammatory reaction and vascular endothelial injury caused by MP infection.

Objective To investigate the prevalence of fatigue symptoms and investigate its related factors in patients with Parkinson's disease (PD).Methods The Parkinson's Fatigue Scale (PFS-16) was used to assess the fatigue status of 453 PD patients.These patients were divided into fatigue group (mean PFS-16≥3.3 defined as fatigue) and non-fatigue group.All of them completed the assessment of the relevant scale.Results Among 453 PD patients,there were 169 patients (37.3％) in fatigue group and 284 patients (62.7％) in non-fatigue group.Unified Parkinson's disease Rating Scale (UPDRS) and HoehnYahr (H-Y) staging in fatigue group were significantly higher than non-fatigue group (P ＜0.05).Motor symptoms,mental and emotional status and daily living ability are positively correlated with fatigue symptoms.Conclusions The motor symptoms and non-motor symptoms are more serious in PD patients with fatigue.The motor symptoms,mental and emotional status,daily living ability and Hoehn-Yahr (H-Y) stage are the main related factors of fatigue symptoms in PD patients.

Objective o investigate the clinical characteristics and relevant risk factors of freezing gait in patients with Parkinson's disease (PD).Methods A total of 570 consecutive PD patients were registered basic information and evaluated by Unified Parkinson's Disease Rating Scale (UPDRS) and New Freezing of gait questionnaire (NFOG-Q).They were divided into the PD with freezing gait group (188 cases) and non-freezing gait group.Results UPDRS score in each part (UPDRS-Ⅰ,UPDRS-Ⅱ,UPDRS-Ⅲ,UPDRS-Ⅳ) and Hoehn & Yahr stage of the PD freezing gait group was significantly higher than that of the non frozen gait group (P ＜ 0.05).Conclusions PD patients with frozen gait group experience more rapid PD progression than those without freezing of gait.The appearance of FOG is associated with the mental behavior and emotion,treatment complication,disease severity,and course of PD.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).
