Objective To evaluate functional activity of the subcortical nuclei in Wilson's disease (WD) using resting state functional MRI (rs-fMRI),and to evaluate damage to the functional conjunction in the extracorticospinal tract in WD patients.Methods Twenty-two patients with WD (between January 2015 and January 2016),including 18 with cerebral type and 4 with hepatic type,and 20 age-matched healthy controls were enrolled.Neurological symptoms were scored using the modified Young Scale.Patients with cerebral type WD were divided into 4 subgroups.All study subjects underwent rs-fMRI of the brain.The values of amplitude of low-frequency fluctuation (ALFF) and regional homogeneity (REHO) in the thalamus,caudate nucleus,putamen and globus pallidus were determined.The relationships between rsfMRI metrics and clinical status were evaluated.Results ALFF values were lower in the caudate nucleus,putamen and right thalamus of WD patients than in controls (t =-3.07,-3.00,-3.12,-2.46,-2.20;P =0.005,0.006,0.004,0.020,0.036),while REHO values were lower in the left caudate nucleus and left thalamus of WD patients (t =-2.38,-2.16;P =0.025,0.040).In the caudate nucleus (P =0.032,0.029,0.023),thalamus (P =0.022,0.041,0.035) ALFF values were lower in group 4 than in other groups.REHO values of the putamen (P =0.040,0.017,0.040) and thalamus (P =0.024,0.029 7,0.041) were higher in group 4 than in other groups.ALFF values in the caudate nucleus (t =-0.29,P=0.037),and thalamus (t =-1.77,P =0.042) were lower,and REHO values in the caudate nncleus (t =-1.46,P =0.040) were lower,in patients of cerebral type than in hepatic type patients.Conclusions The damage to the functional activity of the subcortical nuclei may occur in the WD patients.The functional activity of nuclei may be different between hepatic and cerebral type patients.Damage to the activity of neurons in the putamen and thalamus may correlate with psychiatric symptoms in WD patients.

Objective To evaluate the effect of lumbar multifidus muscle training on muscle thickness.Methods The morphological changes in volunteers' lumbar multifidus muscles were observed in response to 11 kinds of training.Muscle thickness was measured at rest and during contraction using ultrasonography and two examiners.The rate of change in muscle thickness and the contraction rate were calculated.Results There was no significant difference in the contraction rates determined by the two examiners using ultrasound imaging.There was no significant difference in average contraction rate between the males and females.Pairwise,there was no significant difference among contralateral leg-raising,ipsilateral leg-raising,contralateral hand-raising,ipsilateral hand-raising and contralateral leg-lifting.Pairwise,there was no significant difference among ipsilateral leg-lifting and ipsilateral arm-lifting compared with contralateral leg-lifting,contralateral arm-lifting or contralaleral lower limb-lifting.There was no significant difference between contralateral arm-lifting and ipsilateral arm-lifting.There was no significant difference between ipsilateral arm-lifting with contralateral leg-lifting and contralateral arm-lifting with ipsilateral leg-lifting.Pairwise,there was a significant difference in lumbar multifidus muscle contraction rates among these actions.Conclusion Lumbar multifidus muscle training has various effects.Muscle thickness as measured using ultrasonography can provide a basis for formulating a rehabilitation training plan.

Objective To investigate the value of neurite orientation dispersion and density imaging (NODDI) in quantitative evaluation of the microstructural changes in basal ganglia and thalamus in Wilson's disease (WD) patients,and to assess the diagnostic efficacy of NODDI.Methods Totally 27 WD patients (WD group) and 26 age-and sex-matched controls (control group) were enrolled.All subjects underwent MR scanning with NODDI.Parameters of NODDI,including intracellular volume fraction (Vic),orientation dispersion index (ODI) and isotropic volume fraction (Viso) of bilateral caudate nucleus,globus pallidus,putamen and thalamus were compared between the 2 groups.Correlation analysis was performed between each parameter of NODDI and clinical Young scores.Random Forest model was used to assess the relative importance of each parameter and to evaluate the diagnostic efficacy.Results The Vic and ODI of bilateral caudate nucleus,globus pallidus and putamen in WD patients were significantly lower than those in normal controls (all P＜0.05),while Viso was significantly higher than that in normal controls (all P＜0.05).The Vic of bilateral thalamus was lower,while Viso was higher in WD patients than those in normal controls (all P＜0.05),and ODI had no significant difference between the 2 groups (P=0.055).In WD patients,Vic and ODI of bilateral caudate nucleus,globus pallidus and putamen were negatively correlated with clinical Young scores.Viso of globus pallidus and putamen were positively correlated with clinical scores.The prediction accuracy of NODDI was 96.23％,and the area under ROC curve was 0.96.Conclusion NODDI can effectively evaluate changes in microstructures and metabolism during copper deposition in WD patients,and it may be useful in detecting changes of brain deep nuclei and assessing the progression of WD.

Objective:To explore the relationship between lipid accumulation product (LAP) and disease activity, nutritional status in patients with Crohn disease (CD).Methods:The clinical data of 74 patients with CD in the Affiliated Hospital of Yangzhou University from July 2020 to June 2021 were retrospectively analyzed. The patients were divided into active group (32 cases) and remission group (42 cases) according to simplified Crohn disease activity index (CDAI). The general clinical data, laboratory examination results and body fat indexes were recorded, body fat indexes including body mass index (BMI), waist circumference, waist-to-height ratio, LAP and nutritional risk screening 2002 (NRS2002) score. Spearman method was used for correlation analysis; the receiver operating characteristic (ROC) curve was drawn to analyze the efficacy of LAP in predicting the disease activity and nutritional status in patients with CD.Results:The proportion of males, body weight, hemoglobin, albumin, total cholesterol, triglyceride and high-density lipoprotein cholesterol in active group were significantly lower than those in remission group: 46.9% (15/32) vs. 71.4% (30/42), (53.58 ± 8.13) kg vs. (61.05 ± 9.38) kg, (109.94 ± 23.70) g/L vs. (134.19 ± 18.03) g/L, (34.01 ± 5.71) g/L vs. (39.15 ± 4.27) g/L, (3.23 ± 0.68) mmol/L vs. (3.66 ± 0.74) mmol/L, (1.12 ± 0.36) mmol/L vs. (1.34 ± 0.55) mmol/L and (0.91 ± 0.23) mmol/L vs. (1.04 ± 0.33) mmol/L, the nutritional risk rate, platelet count, C-reactive protein and erythrocyte sedimentation rate were significantly higher than those in remission group: 68.8% (22/32) vs. 19.0% (8/42), (317.97 ± 130.19) ×10 9/L vs. (194.00 ± 51.91) × 10 9/L, 14.15 (6.15, 41.35) mg/L vs. 1.51 (0.22, 5.58) mg/L and 40.00 (20.50, 64.25) mm/1 h vs. 9.00 (3.00, 20.00) mm/1 h, and there were statistical differences ( P<0.01 or <0.05); there were no statistical difference in age, height, total protein and low-density lipoprotein cholesterol between the two groups ( P>0.05). The BMI, waist circumference, waist-to-height ratio and LAP in active group were significantly lower than those in remission group: 19.46 (17.70, 21.45) kg/m 2 vs. 21.08 (18.87, 23.12) kg/m 2, (72.51 ± 5.92) cm vs. (77.67 ± 7.27) cm, 0.44 ± 0.03 vs. 0.46 ± 0.04, 13.42 (5.07, 17.72) cm·mmol/L vs. 15.49 (9.37, 31.71) cm·mmol/L, the NRS2002 was significantly higher than that in remission group: 3.00 (1.00, 3.75) scores vs. 1.00 (0, 2.00) scores, and there were statistical differences ( P<0.01 or <0.05).

Conclusions:LAP has good predictive value for disease remission and nutritional status improvement in patients with CD.

Objective:To investigate the effects of personalized intermittent energy restriction (IER) diet on sleep related gut microbiome in obese patients.Methods:In this single-arm clinical trial, a total of 35 obese patients who visited Henan Provincial People′s Hospital from April to November 2018 were recruited as research subjects. They underwent a strict 32-day IER diet intervention, divided into 4 stages of 8 days each. Nutritional recipes were formulated and nutritious meals were provided to each obese patient with timed meals, including 55% carbohydrates, 15% protein, and 30% fat per meal. In stages 1, 2, 3, and 4, patients were provided with 2/3, 1/2, 1/3, and 1/4 of their previous calorie intake every other day, respectively, with meals at 8:00 and 16:00. During the remaining time, patients were allowed unrestricted eating at home. Physiological indicators (weight, body mass index, body fat percentage, waist circumference, hip circumference, fasting blood glucose, glycosylated hemoglobin, blood pressure, triglycerides, total cholesterol, high-density lipoprotein, low-density lipoprotein and Pittsburgh Sleep Quality Index (PSQI) scores were observed before and after the intervention. Gut microbiota changes were analyzed using metagenomic sequencing technology, and Spearman′s correlation analysis was used to assess the correlation between significantly different bacterial species and PSQI scores.Results:After the intervention, the body weight, body mass index, and PSQI scores of obese patients were all significantly lower than before intervention [(89.92±14.98) vs (97.53±15.67) kg, (31.94±3.95) vs (34.64±4.05) kg/m 2, (3.43±1.16) vs (5.42±2.27)], the abundance of gut microbiota was significantly higher after the intervention (all P<0.05). There were 45 significantly different bacterial species before and after the intervention, of which 6 bacterial species ( Enterobacter cloacae, Escherichia coli, Odoribacter splanchnicus, Oribacterium sinus, Streptococcus gordonii, and Streptococcus parasanguinis) showed significantly positive correlations with PSQI scores ( r=0.476, 0.475, 0.369, 0.391, 0.401, 0.423) (all P<0.05), and they were mainly enriched in the glutamate and tryptophan synthesis pathways. Conclusions:The personalized IER diet intervention can improve the sleep of obese patients while reducing weight, possibly mediated by changes in gut microbiota through the glutamate and tryptophan pathways.
