Autism spectrum disorder(ASD),characterized by unknown etiology and high heterogeneity,ne-cessitates precise diagnostic and intervention strategies.Neuroimaging techniques have shown great promise in un-covering the neural mechanisms of ASD,providing a foundation for aided diagnosis and transcranial magnetic stim-ulation(TMS)interventions.This review highlights that integrating multimodal neuroimaging and developing indi-vidualized indices with developmental specificity can significantly improve the accuracy of ASD diagnosis and clas-sification.Furthermore,TMS interventions guided by functional connectivity derived from functional magnetic reso-nance imaging(fMRI)offer a personalized approach to ASD treatment.

Autoimmune thyroid disease(AITD)is a common organ-specific autoimmune disease.The pathological features are significantly increased titers of Thyroglobulin antibody(TgAb)and/or Thyroid peroxidase antibody(TPOAb),accompanied by lymphocyte infiltration in thyroid tissue.The incidence of this disease is increasing year by year,its pathogenesis is complex,and its complications such as Hashimoto's encephalopathy,infertility or abortion,and related nephropathy are harmful.Therefore,this disease has become one of the research hotspots in this field.Animal models play a crucial role in basic disease research.In recent years,many scholars have revealed the etiology,pathogenesis,complications,and therapeutic intervention mechanisms of traditional Chinese and Western medicine through different animal models of AITD.In this paper,animal selection,specific modeling methods and model evaluation of mouse models of AITD and its complications in recent years were summarized and analyzed,so as to provide a reference for the selection of animal models for AITD basic experimental research.

Many brain disorders do not show visible lesions and most likely are resulted from abnormalities in regional brain activity or connectivity.Conventional diagnostic neuroimaging techniques are not capable of precisely localizing the abnormal brain activity,but the recently developed integrated PET/MR technology may have the potential to bridge this gap.Integrated PET/MR has been used in clinical practice.However,its primary application is still a combination of functional PET imaging and structural MRI.Simultaneous PET/fMRI,a "functional+functional" imaging technique,holds the advantages of high spatial and temporal resolution,high sensitivity and specificity,and non-invasiveness.Globally,simultaneous PET/fMRI research is still in its beginning stage,and a few initial PET/fMRI studies have shown that voxel-wise correlation between PET and fMRI metrics was not very high,indicating that they may reflect very different aspects of brain activity.To date more than 5 integrated PET/MR scanners have been set up in mainland China.China has the largest patient population,rapidly developing PET imaging techniques,and well-established capabilities in fMRI neuroimaging analytics.PET/fMRI studies require multi-disciplinary collaborations in nuclear medicine,radiology,chemistry,medical physics,computation science,and cognitive neuroscience.At the moment,the research management system in Chinese hospitals is not conducive to such collaborations and further improvement is needed to encourage multi-disciplinary research such as PET/fMRI.Given the known advantages in patient population and other resources,multi-center and multi-disciplinary studies hold the potential to put China at the leading edge of PET/fMRI research and produce high value results that will advance both neuroimaging sciences and future patient care in brain disorders.

Objective:To estimate the remineralization of enamel of primary teeth with early caries protreated by NaF-chitosan gel.Methods:Early stage caries was created on anterior primary teeth.The samples were divided into 4 groups randomly (n =6),and treated by NaF-chitosan gel,chitosan gel,duraphat and non-treatment(the control) respectively.Then all samples were underwent a 7days pH cycle.Then samples were tested with SEM and EDS.Data were analyzed with SPSS 19.Results:The SEM data showed that chitosan gel protected the enamel surface from being mined by erosion.NaF-chitosan gel group showed more mineral crystal formation on the enamel surface.The NaF-chitosan gel group showed more Ca remineralized on the enamel surface.Conclusion:NaF-chitosan gel can increase the remineraliztion of on the anterior primary teeth with early stage caries.

Objective To evaluate the effect of sofren injection on acute lung injury (ALI) in septic mice.Methods Ninety-six pathogen-free made Kunming mice,aged 8-10 weeks,weighing 30-35 g,were divided into 4 groups (n =24 each) using a randon number table:sham operation group (group Sham),ALI group,vehicle group (group Vehicle) and sofren injection group (group Sofren).Sepsis was induced by cecal ligation and puncture.In Vehicle and Sofren groups,double distilled water and sofren injection 4 ml/kg were intraperitoneally injected,respectively,after the model was established,followed by repeated admninistration once every 12 h.At 12,24 and 48 h after operation,the animals were sacrificed and lungs were removed for mnicroscopic examination and for determination of wet to dry weight ratio (W/D ratio),malondialdehyde (MDA) content,superoxide dismutase (SOD) activity,and contents of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in lung tissues (by enzyme-linked immunosorbent assay).The lung injury score (LIS) was calculated after haematoxylin and eosin staining.Results Compared with group Sham,the LIS,W/D ratio and contents of MDA,TNF-α and IL-6 were significantly increased,and the SOD activity was decreased at each time point in ALI and Vehicle groups (P＜0.05).Compared with group ALI,the LIS,W/D ratio and contents of MDA,TNF-α and IL-6 were significantly decreased,and the SOD activity was increased at each time point in group Sofren (P＜0.05),and no significant change was found in each parameter mentioned above in group Vehicle (P＞0.05).Conclusion Sofren injection can attenuate ALI in septic mice.

Objective To explore the pattern of spontaneous neural activity in different frequency bands in Parkinson's disease(PD).Methods The blood oxygen level-dependent signals in 39 PD patients and 37 normal controls were acquired and the amplitude of low-frequency fluctuation ( ALFF) in five differ-ent frequecy bands ( slow-2:0.198-0.25 Hz;slow-3:0.073-0.198 Hz;slow-4:0.027-0.073 Hz;slow-5:0.01-0.027 Hz;slow-6:0-0.01Hz) was cacaulated.A repeated-measures analysis of variance and Post hoc t-test were performed to detect differences of spontaneous activity between two groups in different frequency bands. A correlation analysis was examined between Unified Parkinson’ s Disease Rating Scale ( UPDRS) motor score and ALFF in patients with PD in each frequency band to discover the relationship between disease se-verity and spontaneous neural activity.Results Compared with the normal controls,patients with PD had decreased ALFF in the putamen(-24,-3,-9) (-30,3,0) ( -21,9,6) in the slow-3,slow-4 and slow-5, and had decreased ALFF in the left precentral gyrus (-21,-24,75) (-21,-24,72) (-27,-21,72) (-15,-15,72) and right supplementary motor area (21,-24,75) (6,-3,72) (12,-6,60) (15,-24,72) in all frequency bands except for the slow-5.Increased ALFF in the cerebellum was found in all frequency bands.The ALFF in the putamen was negatively correlated with the UPDRS motor score in the slow-3,slow-5 and slow-6.Conclusion This study shows that the abnormal activities in the striatum are significant in the slow-3,slow-4and slow-5.Most frequency bands except slow-5 are helpful in detecting neural changes in mo-tor cortex.The increased activity in the cerebellum is the common findings in all frequency bands.Multiple frequency analysis may provide insight into the pathophysiological mechanisms of PD.
