Purpose To investigate the cortical thickness features in Parkinson's disease(PD)patients at various stages and their association with dopamine transporter(DAT)levels in the putamen.Materials and Methods We retrospectively enrolled 30 PD patients and 15 healthy subject who underwent 11C-CFT PET and T1 MRI scans at the Department of Nuclear Medicine/PET Center of Huashan Hospital from August 2016 to October 2020.DAT average radioactivity in the anterior and posterior putamen was analysis using SPM12 software,with the occipital lobe as the reference region.Cortical segmentation and reconstruction were performed on T1 images using Freesurfer v7.2.The differences in cortical thinning between the groups were compared using a general linear model.Additionally,the relationship between cortical thickness in various brain regions and DAT uptake in the putamen were assessed.Results Compared to healthy subjects,significant cortical thinning was observed in the left inferior parietal lobule and the right and left inferior middle frontal gyrus of PD patients(all P<0.05).There was a significant positive correlation between the cortical thickness of the left inferior parietal lobule and right inferior middle frontal gyrus and DAT uptake in the corresponding anterior/posterior parts of the putamen(r=0.30-0.47,all P<0.05).Furthermore,the DAT uptake in the right precentral gyrus was positively correlated with the ipsilateral posterior putamen,exhibiting a stronger correlation than on the contralateral side(r=0.32,P=0.029).Conclusion The results show that the thickness of the thinning cortex area in the PD patients correlates significantly positively with DAT levels in the putamen,highlighting the importance of the basal ganglia cortical circuit and providing a basis for further research into the neural mechanisms of PD.

Objective To observe the correlation between cortical thickness and pathological deposition of β-amyloid(Aβ)in patients with Alzheimer disease(AD)induced mild cognitive impairment(MCI)or dementia.Methods Totally 22 AD patients were prospectively enrolled and divided into dementia group(n=12)and MCI group(n=10)based on the degree of cognitive impairment,while 17 healthy individuals without cognitive impairment were recruited as control group.MR examination and 18F-florbutaben(18F-FBB)PET imaging were performed,the cortical thickness and Aβ deposition value(Centiloid[CL]value)were calculated and compared among 3 groups and between each 2 groups,then the correlation between the above two indexes was analyzed.Results The cortical thickness in dementia group,MCI group and control group was(2.18±0.14),(2.35±0.08)and(2.36±0.09)mm,respectively,with significant difference among 3 groups(P＜0.05).The cortical thickness in dementia group was significantly thinner than that in MCI group and control group(both P＜0.05).CL value in dementia group,MCI group and control group was 77.97(63.07,95.55),65.51(54.54,90.50)and-1.17(-9.66,4.88),respectively,with significant difference among 3 groups(P＜0.05).CL value in dementia group and MCI group were significantly higher than in control group(both P＜0.05).The cortical thickness was moderately negatively correlated with CL value in MCI group(r=-0.580,P=0.048)but not in the other 2 groups(both P＞0.05).Conclusion The cortical thickness was moderately negatively correlated with abnormal deposition of Aβ in patients with AD induced MCI,but was not during dementia.

Objective:To explore the effects of transcutaneous electrical nerve stimulation(TENS)on knee joint pain,func-tion,muscle strength and gait in patients with knee fracture surgery.Method:Forty patients with knee fractures were divided into the control group and the experimental group,with 20 cases in each group.Strength training,joint mobilization techniques,neuromuscular electrical stimula-tion,and routine rehabilitation training were provided to the control group.The experimental group was given the same routine rehabilitation program,except the TENS intervention instead of neuromuscular electrical stimu-lation.For six weeks,each treatment was given once daily over five days.All the patients were evaluated by Visual analogue score(VAS),American hospital for special surgery knee score(HSS-KS),isometric muscle strength test and 3-D gait analysis before and after treatment.Result:There was no significant difference between the two groups in each evaluation scores before treatment(P＞0.05).HSS-KS score,peak torque per bodyweight of knee extensors and flexors under 60°/s and 180°/s,and gait parameters in both groups were significantly improved after 6 weeks of treatment,compared to those before treatment(P＜0.05).Meanwhile,the experimental group were significantly better than the control group in terms of the VAS score and HSS-KS score,peak torque/body weight(PT/BW)at 60°/s and 180°/s of knee extensors,and subparts of gait parameters(P＜0.05).Conclusion:In patients with knee fractures surgery,TENS can significantly minimize the pain,improve knee function and gait pattern,and strengthen the absolute force of knee extensors.

Objective:To analyze the incidence trend of lip and oral cancer in China from 1990 to 2021.Methods:The incidence data of lip and oral cancer in China from 1990 to 2021 were obtained through the Global Health Data Exchange (GHDx) database, including incidence rates by gender and age-standardized incidence rates. Joinpoint regression was used to analyze the trend of lip and oral cancer incidence rate. Age-period-cohort (APC) model was adopted to estimate the effects of Age, Period and Cohort on the incidence of lip and oral cancer in China.Results:The crude and age-standardized incidence rates of lip and oral cancer in China from 1990 to 2021 showed an increasing trend, and the crude incidence rates of the whole population, male and female in the year 2021 increased by 216.8%, 266.7% and 130.4%, respectively, compared with 1990. The age effect, period effect and birth cohort effect of the incidence risk of lip and oral cancer in China were statistically significant (all P<0.05). People of older the age and the more recent the birth cohort, the higher the incidence risk. Conclusions:The incidence of lip and oral cancer is on the rise in China from 1990 to 2021. Age, period and birth cohort are all the factors affecting the incidence of lip and oral cancer.

Objective:To investigate the value of 3.0T magnetic resonance imaging(MRI)in the assessment for clinically pathologic features of prostate cancer(PCa).Methods:The case data of 102 PCa patients who were confirmed by histology in The Second Affiliated Hospital of Bengbu Medical University from April 2020 to July 2024 were retrospectively analyzed.51 PCa patients of them were included in cancer group,and 51 patients with prostatic hyperplasia were included in hyperplasia group.Multi-parametric MRI was implemented in all patients.Imaging performance was scored by using Prostate Imaging Reporting and Data System version 2.1(PI-RADS v2.1).The distribution of scores between the two groups was compared and analyzed.The correlations between the PI-RADS v2.1 scores and PCa clinically pathological features which included Gleason scores,serum prostate specific antigen(PSA)level,tumor staging and aggressiveness were analyzed and explored by using Spearman correlation analysis.The diagnostic efficacy of the 3.0T MRI technique for PCa was analyzed by using the receiver operating characteristic(ROC)curve.Results:The PI-RADS v2.1 score of cancer group was 4(4,5)scores,which was significantly higher than 2(3,4)scores of hyperplasia group,and the difference of that between two groups was significant(U=369.5,P<0.05).The rate of high scores(4,5 scores)of cancer group was more than that of hyperplasia group in the distribution of scores,and the difference of that between two groups was significant(x2=51.220,P<0.05).In patients of cancer group,PI-RADS v2.1 score showed significant correlation with serum PSA level,Gleason score,tumor staging and aggressiveness(P<0.05),respectively,and they were significant(r=0.815,0.723,0.693,P<0.05).ROC curve analysis showed that the area under curve(AUC)value of PI-RADS v2.1 score was 0.858(95%CI:0.783-0.932)in diagnosing PCa,which can effectively distinguish PCa and prostate hyperplasia.It had higher diagnostic efficacy,which was higher than that of serum PSA.Conclusions:3.0T MRI has favorable accuracy in diagnosing PCa,and it can be used as a noninvasive test method to diagnose and assess pathological features of tumor.
