Objective To test whether multiplex ligation-dependent probe amplification(MLPA)could be used for the prenatal detection of the most common aneuploidies of chromosomes 13,18,21,X,and Y.Methods 34 cases including 22 blood samples(12 with trisomy 21,1 with monosomy X,one male witll extra Y and 8 healthy persons),4 cord blood samples with Down syndrome and 8 amniotic fluid samples ( 1 with trisomy 21 and 7 normal fetuses)were recruited into this study.All samples were confirmed by karvotype analysis. DNA was extracted from blood and amniotic lysate was incubated with proteinase K.MLPA was used to determine the relative copy numbers.Results The resuhs were available within 48 h and were concordant with karyotype analysis in all but one case of amniotic fluid that was suggested to be triploid sample 69,XXY by MLPA or contaminated by maternal blood.This sample actually was found containing a number of red blood cells after centfifugation in test. In total,the concordance rate with clinical characteristics was 97.1%.The Ratio values of 13,18,21,X in normal samples were approaching 1.0 except chromosome Y having slightly higher variation in relative copy number.The difference of ratio means between the normal and trisomy 21 samples was statistically significant by one-way ANOVA(F=298.906.P=0.000).Conclusion Computer assisted MLPA with high sensitivity is a rapid,simple,automatic and reliable method for detection of common chromosomal aneuploidies.

Objective: To compare the clinical characteristics and plasma level of N-terminal pro-brain natriuretic peptide (NT-proBNP) between the patients with hypertensive hypertrophic cardiomyopathy in elder age (HHCME) and the patients with hypertensive left ventricular hypertrophy (HTN-LVH).
Methods: Our work included 2 groups, HHCME group,n=47 and HTN-LVH group,n=44. Duplex Doppler echocardiography was performed to determine left atrial diameter (LAd), left ventricular end-diastolic dimension (LVEDd), interventricular septal thickness (IVST), left ventricular ejection fraction (LVEF), velocity of early diastolic period (VE) and velocity of end-diastolic period (VA) in mitral valve oriifce. Plasma level of NT-proBNP was measured by ELISA. The above indexes were compared between 2 groups.
Results:①Compared with HTN-LVH group, HHCME group presented decreased LVEDd and increased IVST, LVEF, allP<0.001. There were no signiifcant differences in VE/VA ratio and LAd between 2 groups, allP>0.05.②Plasma level of NT-proBNP was higher in HHCME group,P<0.01. With the adjusted age, gender, history of hypertension, LAd, IVST, left ventricular systolic and diastolic function, the level of NT-proBNP in HHCME group (1317.19 fmol/ml) was still signiifcantly higher than that in HTN-LVH group (526.19fmol/ml),P<0.01.
Conclusion: The plasma NT-proBNP level was higher in HHCME patients than that in HTN-LVH patients which indicated that HHCME patients may have worse prognosis. NT-proBNP might be helpful for differencing HHCME.

Objective: To describe the clinical characteristics with long-term prognosis in patients with mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHCM).
Methods: A total of 66 MVOHCM patients treated in our hospital were retrospectively studied for their morbidity, clinical characteristics and mortality. The cumulative survival rate was calculated by Kaplan-Meier method; the risk factors for cardiac death and cardiovascular events were analyzed by uni- and multivariate Cox proportional hazard model.
Results: There were 66 (2.74%) patients suffering from MVOHCM among 2413 patients of hypertrophic cardiomyopathy and the average diagnostic age was (40.16 ± 14.64) years. With (7.30 ± 6.25) years of follow-up study, the cardiovascular mortality was 13.6% and unexplained syncope (HR=13.37, 95% CI: 1.65-114.46, P=0.015) was the independent predictor for cardiovascular death. There were 45.45% (30/66) patients experienced at least 1 time of cardiovascular event and the most frequent one was non-sustained ventricular tachycardia (NSVT); 19.70% (13/66) of patients combined with apical aneurysms, and they were more inclined to experience NSVT.
Conclusion: MVOHCM patients usually have unfavorable prognosis with the higher incidence of cardiovascular events, some patients may develop apical aneurysm. The early diagnosis of MVOHCM is important for appropriate treatment.

Background: The mechanism of peripheral axon transport in neuropathic pain is still unclear. Chemokine ligand 13 (CXCL13) and its receptor (C-X-C chemokine receptor type 5, CXCR5) as well as GABA transporter 1 (GAT-1) play an important role in the development of pain. The aim of this study was to explore the axonal transport of CXCL13/CXCR5 and GAT-1 with the aid of the analgesic effect of botulinum toxin type A (BTX-A) in rats. Methods: Chronic constriction injury (CCI) rat models were established. BTX-A was administered to rats through subcutaneous injection in the hind paw. The pain behaviors in CCI rats were measured by paw withdrawal threshold and paw withdrawal latencies. The levels of CXCL13/CXCR5 and GAT-1 were measured by western blots. Results: The subcutaneous injection of BTX-A relieved the mechanical allodynia and heat hyperalgesia induced by CCI surgery and reversed the overexpression of CXCL13/CXCR5 and GAT-1 in the spinal cord, dorsal root ganglia (DRG), sciatic nerve, and plantar skin in CCI rats. After 10 mmol/L colchicine blocked the axon transport of sciatic nerve, the inhibitory effect of BTX-A disappeared, and the levels of CXCL13/CXCR5 and GAT-1 in the spinal cord and DRG were reduced in CCI rats. Conclusions BTX-A regulated the levels of CXCL13/CXCR5 and GAT-1 in the spine and DRG through axonal transport. Chemokines (such as CXCL13) may be transported from the injury site to the spine or DRG through axonal transport. Axon molecular transport may be a target to enhance pain management in neuropathic pain.

Objective:To explore the value of machine learning models based on multiple structural MRI features for diagnosis of Parkinson disease (PD).Methods:The clinical and imaging data of 60 PD patients (PD group) diagnosed in the Neurology Department of the Second Affiliated Hospital of Soochow University from November 2017 to August 2019 and 56 normal elderly people (NC group) recruited from the community were retrospectively analyzed. All subjects underwent brain MR imaging. Multiple structural MRI features were extracted from cerebellum, deep nuclei and of brain cortex based on different partition templates. The Mann-Whitney U test, as well as least absolute shrinkage and selection operator regression were used to select the most discriminating features. Finally, logistic regression (LR) and linear discriminant analysis (LDA) classifier combined with the 5-fold cross-validation scheme were used to construct the models based on structural features of cerebellum, deep nuclei and cortex, and a combined model based on all features. The receiver operating characteristic curves were drawn, and the diagnostic performance and clinical net benefit of each model were evaluated by the area under curve (AUC) and the decision curve analysis (DCA). Results:In total, four cerebellum (asymmetry index of Lobule Ⅵ volume, asymmetry index of Lobule ⅦB cortical thickness, asymmetry index of total gray matter volume and absolute value of right Lobule Ⅵ gray matter volume), 3 deep nuclei (absolute value of right nucleus accumbens volume, absolute and relative value of total nucleus accumbens volume) and 3 cortex features (local gyration index of left PFm, local fractal dimension of right superior frontal gyrus and sulcal depth of left superior occipital gyrus) were selected as the most discriminating features, and the related models were constructed. In validation set, the AUC of cerebellum, deep nuclei, cortex and combined models for diagnosis of PD based on LR classifier were 0.692, 0.641, 0.747 and 0.816; the AUC of cerebellum, deep nuclei, cortex and combined models for diagnosis of PD based on LDA classifier were 0.726, 0.610, 0.752 and 0.818. The diagnostic efficiency of the combined models based on LR and LDA classifiers were significantly better than those of other models ( P<0.05). The DCA curve demonstrated that the combined models based on LR and LDA classifiers showed the highest clinical net benefit. Conclusion:The combined models with all structural features of cerebellum, deep nuclei and cortex included based on LR and LDA classifiers showed favorable performance and clinical net benefit for diagnosis of PD, which have the potential application value in clinical diagnosis.
