Very-long chain acyl-coA dehydrogenase deficiency: report of a Chinese pedigree and a literature review / 中华医学遗传学杂志

OBJECTIVE@#To explore the correlation between clinical classification and genotype and prognosis among Chinese children with Very-long chain acyl-CoA dehydrogenase deficiency (VLCADD).@*METHODS@#A Chinese pedigree affected with VLCADD admitted at the First People's Hospital of Yunnan Province in February 2019 was selected as the study subject. The characteristics of disease onset, diagnosis and treatment and prognosis were retrospectively analyzed. Relevant literature was also systematically searched and reviewed.@*RESULTS@#The proband, a 1-year-old boy, had the clinical manifestations of frequently vomiting, hypoglycemia, abnormal liver function and myocardial enzymes. Tandem mass spectrometry screening showed significantly elevated C14, C14:1, C16:1, C16:2, C18 and C14/C8. Genetic testing revealed that he has harbored compound heterozygous variants of the ACADVL gene, namely c.664G>A (p.G222R) and c.1345G>A (p.E449K), which were respectively derived from his father and mother. The child was diagnosed with VLCADD cardiomyopathy type and deceased 2 weeks later. Literature review has identified 60 Chinese children with VLCADD. The clinical classifications were mainly cardiomyopathy type and liver disease type, which accounted for 73.3% (43/60). The combination of ACADVL gene variants were correlated with the clinical classifications of VLCAD. Children with one or two loss-of-function (LOF) mutations showed more severe clinical manifestation and a higher mortality. Cardiomyopathy type had the poorest prognosis, with a mortality rate of 76.9% (20/26). C14:1 may be used as an indicator for the diagnosis of VLCADD, but cannot be used for clinical subtyping and prognosis evaluation. The c.1349G>A (p.R450H) variant had the highest frequency among the Chinese patients, accounting for 10.8% (13/120).@*CONCLUSION@#The clinical classifications of VLCADD are strongly correlated with the prognosis, and LOF mutations are more common in those with severe clinical manifestations. c.1349G>A (p.R450H) may be the most common variant among the Chinese patients, and early screening and diagnosis can greatly improve the prognosis of patients.

Objective:To learn about the epidemic dynamics and spatial epidemic characteristics of human brucellosis in Gansu Province.Methods:Data on human brucellosis in Gansu Province reported by China Disease Control and Prevention Information System from January 2016 to December 2020 were collected and analyzed by descriptive epidemiology and spatial clustering analysis.Results:A total of 10 025 cases of human brucellosis were reported in Gansu Province from 2016 to 2020, with a statistically significant difference in incidence rate between years (χ 2 = 242.86, P = 0.001). The incidence was the lowest in 2018 (6.03/100 000), and the highest in 2020 (11.39/100 000). The reported cases were concentrated in 45 - 55 years old, accounting for 34.52% (3 461/10 025); the male to female ratio was 2.91 ∶ 1.00 (7 458/2 567); farmers were the main occupation, accounting for 82.11% (8 232/10 025). Among the 86 counties (cities, districts) in Gansu Province, Yongchang County had the highest number of reported cases in 2020 (339 cases), and Sunan Yugur Autonomous County had the highest incidence in 2020 (190.89/100 000). Spatial autocorrelation analysis showed that there was significant spatial positive correlation between the incidence rate of human brucellosis in Gansu Province from 2016 to 2020 (global Moran's I > 0, Z > 1.96, P < 0.05), showing a spatial clustering distribution. The high-high clustering areas were concentrated in Yongchang County and Sunan Yugur Autonomous County. Conclusion:In Gansu Province, the main population of human brucellosis is middle-aged male farmers, and the incidence of brucellosis is spatially clustered.

Establishment of prediction model for severe acute pancreatitis complicated with abdominal hypertension / 中华胰腺病杂志

Objective:To construct the prediction model of SAP complicated with intra-abdominal hypertension (IAH), and evaluate the prediction efficiency of the model.Methods:The clinical data of 322 SAP patients admitted to the emergency department of Cangzhou Hospital of Integrated Chinese and Western Medicine in Hebei Province from January 2017 to December 2021 were retrospectively analyzed. They were divided into IAH group ( n=153) and control group ( n=169) according to whether they had IAH complications or not. The clinical characteristics and laboratory test results of the two groups were compared. Multifactor logistic step-up regression was used to analyze the risk factors of SAP patients complicated with IAH. A nomogram model for predicting SAP complicated with IAH was established by using R software. The receiver operating characteristic curve (ROC) of the model was plotted, and the area under the curve (AUC) was calculated to evaluate its prediction efficiency. Calibration chart, Hosmer-Lemesshow test and decision curve analysis were used to evaluate the prediction accuracy and clinical application value of the model. The Bootstrap method was applied to verify the model internally. Results:In IAH group, cases with body mass index, CRP, procalcitonin (PCT), WBC, acute physiological and chronic health assessmentⅡ (APACHEⅡ) score, modified CT Severity Index score (MCTSI), incidence of complications (abdominal effusion, abdominal infection, gastrointestinal dysfunction, shock, multiple organ dysfunction syndrome), mechanical ventilation, the number of high-volume fluid reactivation (24 h≥4 L) were more than those in control group; serum albumin and serum calcium in IAH group were lower than those in control group, and the differences were statistically significant (all P value <0.05). Multivariate logistic regression analysis showed that serum albumin ( OR=0.815, 95% CI 0.710-0.937), CRP ( OR=1.005, 95% CI 1.002-1.008), MCTSI ( OR=2.043, 95% CI 1.695-2.463), complication of gastrointestinal dysfunction ( OR=4.179, 95% CI 2.170-8.049), and high-volume fluid resuscitation ( OR=4.265, 95% CI 2.269-8.015) were independent risk factors for IAH in SAP.The Nomogram prediction model was established using the five factors above as parameters, and the AUC value for predicting IAH complication was 0.886. The Hosmer-Lemesshow test showed a high consistency between the prediction results and the actual clinical observation results ( P=0.189). The results of decision curve analysis showed that the prediction probability of the model was between 10% and 85%, which could bring more benefits to patients. Conclusions:The early prediction model of SAP with concurrent IAH is successfully established, which can better predict the risk of SAP with concurrent IAH.

Current Status and Progress of Diagnostic Techniques for Cancer of Unknown Primary / 肿瘤防治研究

Cancer of unknown primary (CUP) is a heterogeneous tumor type that has been diagnosed as a metastatic tumor by pathological examination, but the primary tumor cannot be identified through comprehensive clinical examination. The incidence of CUP accounts for approximately 1%–2% of all tumors. CUP progresses rapidly and has a short course. The treatment and prognosis of patients with CUP are closely linked to the primary site. In clinical settings, identifying the primary tumor remains challenging. Scholars have focused on improving the detection rate. Novel technologies, such as gene expression profiling, high-throughput sequencing, epigenetics, and liquid biopsy, have been successively applied to identify the primary tumor of CUP accurately, sensitively and specifically. With the guidance of molecular diagnosis, targeted therapy, immunotherapy, and combination therapy will usher in the era of precision treatment for CUP, which may become a typical example for individualized therapy.

Melatonin Ameliorates the Progression of Alzheimer's Disease by Inducing TFEB Nuclear Translocation, Promoting Mitophagy, and Regulating NLRP3 Inflammasome Activity.

Background: The NLRP3 inflammasome is overactivated in the brains of APP/PS1 transgenic mice and AD patients, and mitophagy has an obvious negative regulatory role on NLRP3 inflammasome activation. The protective effect of melatonin in AD may be related to the regulation of mitophagy and NLRP3 inflammasome activity. TFEB plays a critical role in maintaining autophagy/mitophagy. Studies have found that TFEB plays a protective role in AD. Methods: APP/PS1 transgenic mice were given melatonin in their drinking water for 3 months. Compared with mice without melatonin treatment, the mice given melatonin showed changes in the following features: (1) cognitive function, (2) mitophagy-related proteins in the brain, (3) ROS, (4) NLRP3 inflammasome and related proteins and the concentrations of inflammatory cytokines, and (5) Aß deposition. In in vitro experiments, effects of melatonin on mitophagy, NLRP3 inflammasome activity, and TFEB in SH-SY5Y cells with Aß 25-35 were observed. TFEB knockdown was implemented in combination with Aß 25-35 and melatonin treatment, and the expressions of TFEB, Parkin, p62, IL-1ß, caspase-1, ROS, and IL-18 were explored. Results: Melatonin improved cognitive function in APP/PS1 transgenic mice and decreased ROS and senile plaques. Melatonin promoted mitophagy in SH-SY5Y cells with Aß 25-35 and APP/PS1 transgenic mice. NLRP3 inflammasome activity was inhibited, and the concentrations of IL-18 and IL-1ßwere clearly reduced. Compared with C57/BL6J mice, the amount of TFEB in the brain nucleus of APP/PS1 transgenic mice was decreased. Melatonin treatment increased the nuclear translocation of TFEB in SH-SY5Y cells. TFEB knockout was implemented in combination with Aß 25-35 and MT treatment; the expressions of Parkin, p62, caspase-1, IL-1ß, IL-18, and ROS were accelerated. Conclusions: Melatonin promotes mitophagy by inducing TFEB nuclear translocation, downregulates NLRP3 inflammasome activation, and exerts protective effects in SH-SY5Y cells and APP/PS1 transgenic mice.

Exploring the determinants of influenza A/H7N9 control intervention efficacy in China: Disentangling the effect of the '1110' policy and poultry vaccination.

The influenza A virus of the H7N9 subtype (FLUAV H7N9) emerged in Eastern China provinces in 2013 causing illness in both poultry and humans. Most reported FLUAV H7N9 human cases were related to those associated with the live poultry market chain. From 2013 to 2017, there were five epidemic waves of human infections, and from the end of 2016, the number of human cases increased sharply. To control FLUAV H7N9 in the market chain, the so-called '1110' policy at live poultry markets and a national vaccination programme were implemented. The relative efficacy of these two measures on the number of poultry and human infections has not been quantified and compared. To explore their efficacy, a cross-sectional study was conducted in six provinces of China, and the vaccination and surveillance data of H7N9 were analysed. Our survey data showed that poultry vendors were not widely aware of and did not accept the '1110' policy. For subjective and objective factors, some measures of the '1110' policy were not implemented in live bird markets (LBMs). However, the national vaccination programme achieved good immune effects and sharply decreased poultry FLUAV H7N9 infections. The detection rates of FLUAV H7N9 in LBMs and farms gradually decreased since the vaccination programme was implemented. Our analysis also indicated that human infections were closely related to poultry virus carriage rates; therefore, controlling FLUAV H7N9 circulation in poultry was an effective measure to control FLUAV H7N9 infections in humans. Although LBMs play a significant role in human infections, the management measures may not be implemented efficiently; hence, we need to conduct more investigations before developing related policies.

Objective@#To investigation the correlation between sleep duration and hypertension among adults in Zhejiang Province, and to provide scientific evidence for the prevention and control of hypertension.@*Methods@#Permanent residents at age of 18 years and older were enrolled from 10 surveillance sites for risk factors of chronic diseases included in the 2018 China Chronic Diseases and Risk Factors Surveillance Program. Subjects' demographic characteristics, smoking, alcohol consumption, sleep duration and development of hypertension were collected, and following complex weighting calculations, the association between sleep duration and hypertension were examined using a multivariable logistic regression model.@*Results@#Totally 5 770 adults were included, including 2 952 men (50.72%) and 3 178 women (49.28%), and the prevalence of hypertension was 29.39% (2 702 cases). There were 712 (8.37%), 1 077 (18.77%), 1 582 (28.68%), 1 717 (34.60%) and 682 adults (9.57%) with sleep duration of <6 h/d, 6 to 7 h/d, 7 to 8 h/d, 8 to 9 h/d and 9 h/d and longer, respectively. Taking the sleep duration of 7 to 8 h/d as a reference, multivariable logistic regression analysis identified a significant association between sleep duration of <6 h/d and the risk of hypertension (OR=1.709, 95%CI: 1.184-2.466), a significant association between sleep duration of 9 h/d and longer and the risk of hypertension (OR=1.369, 95%CI: 1.006-1.862) in men, significant associations between sleep duration of <6 h/d (OR=2.174, 95%CI: 1.528-3.093) and 6 to 7 h/d (OR=1.412, 95%CI: 1.078-1.850) and the risk of hypertension in women, and significant associations between sleep duration of <6 h/d (OR=3.095, 95%CI: 1.025-9.347) and 6 to 7 h/d (OR=2.046, 95%CI: 1.156-3.622) and the risk of hypertension in residents at ages of 18 to 44 years.@*Conclusions@#Short sleep duration may increase the risk of hypertension among adults at ages of 18 to 44 years in Zhejiang Province. Short sleep duration may increase the risk of hypertension in women and long sleep duration may increase the risk of hypertension in men.

Objective:To discuss the clinical features, diagnosis and treatment of linear scleroderma (LS).Methods:A case of LS diagnosed in the Second Hospital of Shandong University in October 20, 2020, was reported and the clinical features and pathological documentation of the disease reported in the literature were reviewed.Results:A 24-year-old woman presented cicatricial alopecia on the left frontoparietal area and facial atrophy for about 10 years. Two years before, she began to suffer ptosis and neurological complaints. Clinical features of different stages of the disease are presented. All 15 patients reported in the literature were analyzed, with a median of 22 years and a male to female ratio of 9∶6. There were 4 cases of linear scleroderma with ipsilateral drooping eyelids and lateral contraction, 3 cases of linear scleroderma with demyelinating lesions, combined with lateral contraction, 3 cases of linear scleroderma combined with lateral atrophy, and 1 case of linear scleroderma with ipsilateral facial spasm. Two cases were with the chest sclerosing spot. Two cases of linear scleroderma were with epileptic seizure and white matter demyelination lesion. Six cases were treated with hormone, 2 cases were treated with methotrexate. One case was treated with both hormone and methotrexate. One case was treated with botulinum toxin. Three cases were treated with surgical correction of eyelid ptosis. One case was treated with ultraviolet A1 radiation phototherapy and 1 case was treated with vitamin therapy.Conclusions:Patients with scleroderma may have ipsilateral facial atrophy, blepharoptosis and facial spasm. Some patients involving the nervous system may have epilepsy and myelitis. And demyelinating lesions can be seen in magnetic resonance imaging. Localized scleroderma may develop into systemic scleroderma. Therefore, it is recommended to combine immunosuppressants as soon as possible to control the development of the disease if necessary.

The effect and mechanism of dihydroartemisinin on triple-negative breast cancer MDA-MB-231 cells / 西安交通大学学报(医学版)

【Objective】 To study the inhibitory effect of dihydroartemisinin （DHA） on triple negative breast cancer MDA-MB-231 cells and its mechanisms. 【Methods】 CCK-8 method was used to detect the inhibitory effects of DHA， artemisinin derivative， on the proliferation of triple negative breast cancer MDA-MB-231 cells. qRT-PCR and Western blot were used to test the expressions of CIZ1， Snail and TGF-β1 at mRNA and protein levels. After the exogenous application of TGF-β1 cytokines or TGF-β1 pathway inhibitor SD-208， Wound healing， Transwell invasion assay and Western blotting were performed to detect the effects of activation/inhibition of TGFβ1-smads pathway on the anti-metastatic effects of DHA and its mechanisms. 【Results】 DHA could significantly inhibit the proliferation of human breast cancer MDA-MB-231 cell lines in a dose-dependent manner. It could significantly suppress CIZ1， Snail， and TGF-β1 expressions at mRNA and protein levels in MDA-MB-231 cells. TGF-β1 cytokines treatment could enhance the migration and invasion ability of breast cancer cell， where TGF-β1 treatment also enhanced CIZ1， snail protein expression and smad2/3 protein phosphorylation level. DHA could reverse the above TGFβ1-induced effects. Furthermore， after the application of the TGF-β1 pathway inhibitor SD-208， the anticancer activity of DHA was enhanced， and the expressions of CIZ1， snail and phos-smad2/3 proteins were significantly inhibited. 【Conclusion】 DHA could significantly inhibit the proliferation and metastasis of breast cancer cells through suppressing the TGF-β1/Smad and CIZ1 signaling.

Regulation of capsaicin receptor TRPV1 on depressive behavior and neuronal autophagy in cerebral ischemia-reperfusion mice / 中华行为医学与脑科学杂志

Objective:To explore the effect and molecular mechanism of capsaicin receptor(TRPV1) on neuronal autophagy and depression-like behavior in mice.Methods:Using the method of random number table, 87 C57 male mice were divided into Sham operation group (Sham group), cerebral ischemia/reperfusion group (I/R group) and capsazepine(CPZ) preconditioning cerebral ischemia/reperfusion group (I/R+ CPZ group), with 28 mice in each group due to 3 incompatible.Mice in the I/R group were subjected to right middle cerebral artery occlusion (MCAO) to establish a cerebral ischemia-reperfusion model.Mice in the I/R+ CPZ group were injected with CPZ in the lateral ventricle prior to moulding.Mice in the Sham group had only wire plugs inserted and no arterial embolization was performed.The mNSS score was used to evaluate the degree of neurological deficits.The depression-like behaviour of mice was detected by the tail suspension test and forced swimming test.The infarct volume was observed by TTC staining.The pathological changes in the amygdala were observed by HE staining, and the expression of Beclin-1, LC3, p62 and p-PI3K, p-AKT and p-mTOR proteins were detected by Western blot.Statistical analysis was performed using SPSS 23.0 software.The t-test was used for comparison between two groups and one-way ANOVA was used for comparison of multiple group. Results:The neurological deficit score in I/R+ CPZ group (9.77±2.32) was significantly lower than that in I/R group (12.85±2.73) ( t=3.10, P<0.01). Compared with I/R group, the tail suspension immobility time of I/R+ CPZ Group ((93.28±50.69)s, (143.80±35.61) s; t=2.94, P<0.01) and the forced swimming immobility time ((139.50±13.33)s, (175.30±19.78)s; t=2.94, P<0.01) were significantly reduced.The results of TTC staining showed that the cerebral infarct volume in I/R+ CPZ group was significantly lower than that in I/R group ((19.30±5.19)%, (33.60±3.90)%; t=5.40, P<0.01). HE staining showed that the number of cells in the amygdala region of mice in the I/R+ CPZ group increased compared with that in the I/R group, with tighter arrangement and reduced deep staining of nuclear fixation.Western blot showed that compared with I/R group, the expression levels of autophagy related proteins Beclin-1( t=2.94, P<0.05) and LC3 ( t=3.16, P<0.05) in amygdala of I/R+ CPZ group were down-regulated, while the expression levels of p62( t=3.60, P<0.05), p-PI3K ( t=7.79, P<0.01), p-AKT ( t=4.15, P<0.01) and p-mTOR ( t=6.15, P<0.01) were up-regulated. Conclusion:Cerebral ischemia/reperfusion activates neuronal autophagy, and CPZ may regulate the PI3K-AKT-mTOR pathway, thus inhibits excessive activation of autophagy, thereby acting as a neuroprotective agent and improving post-stroke depression-like behaviour.

Application of innovative PBL in pathophysiology teaching / 中华医学教育探索杂志

Pathophysiology is a comprehensive subject, which is very important to cultivate the clinical comprehensive thinking of medical students. Pathophysiology involves a wide range of subjects and contents, and is one of the major and difficult courses in basic medicine. Based on many years of research and practice, we have developed main-line-problem-based learning (ML-PBL). ML-PBL is a diversified teaching mode, including the main line teaching method, clinical case discussion method, and the main line synopsis explaining method. The analysis of application results shows that ML-PBL teaching improves the student performance. Furthermore, ML-PBL is more conducive to cultivating the comprehensive clinical thinking ability, improving the independent learning ability, and fully mobilizing the learning initiative.

Clinicopathological study of BCOR rearrangement in high grade endometrial stromal sarcoma / 中华病理学杂志

Objective@#To investigate clinicopathological, cytogenetic features and differential diagnoses of high grade endometrial stromal sarcoma (HGESS) with BCOR gene rearrangement.@*Methods@#Five cases of HGESS with BCOR rearrangement were collected from consultant files (2016-2018) at Fudan University Shanghai Cancer Center. Interphase FISH was performed using a dual color break-apart probe. The clinical data, histologic features and immunohistochemical findings were reviewed.@*Results@#All 5 cases occurred in adult women with a median age of 48 (range, 45-55) years. Abdominal pain and abnormal vaginal bleeding were the most common symptoms. Microscopically, the tumors showed mainly tongue-like and/or intersecting myometrial invasion. Stromal myxoid matrix and/or collagen plaques were prominent in all the cases. Most tumors consisted of uniform, haphazard fascicles of short spindle cells with mild to moderate nuclear atypia. Mitotic figures and necrosis were easily identified. Significant nuclear pleomorphism was not seen. Most tumors were rich in thick-walled small vessels. Prominent perivascular tumor cell whorling seen in conventional low-grade endometrial stromal sarcoma was not seen. All tumors expressed CD10 with only focal or absent desmin, SMA and/or h-caldesmon staining. ER or PR expression was seen in 4 tumors and 1 tumor showed both marker expression. Diffuse cyclin D1 was present in 2 tumors. BCOR immunoreactivity was present with strong staining in 3 cases and moderate staining in 1 case respectively. Ki-67 index ranged from 10% to 30%. Fluorescence in situ hybridization confirmed chromosomal aberration of BCOR gene in all tumors, that were previously diagnosed as myxoid leiomyosarcoma (2 cases), spindle cell uterine sarcoma (2 cases) and low-grade endometrial stromal sarcoma (1 case). Limited follow-up information revealed that 3/5 patients developed tumor recurrence, metastasis or death within one year.@*Conclusion@#BCOR rearranged HGESS has distinct morphological features and aggressive clinical behavior. In the presence of significant overlapping morphologic features between BCOR rearranged HGESS and other myxoid uterine mesenchymal tumors, especially myxoid leiomyosarcoma, molecular analysis is essential for accurate diagnoses.

Expression and clinical significance of prohibitin in breast cancer based on bioinformatics / 临床检验杂志

Objective@#To analyze the expression and clinical significance of prohibitin (PHB) in invasive breast cancer (BC) based on high throughput multi-omics databases. @*Methods@#The breast cancer data were downloaded from TCGA and METABRIC databases, and the expressions of PHB in BC tissues and adjacent normal tissues were compared by various bioinformatics tools. The correlations of PHB expression with clinicopathological features and prognosis of BC patients were analyzed, and the interaction and function of PHB protein were predicted. @*Results@#Compared with adjacent normal tissues, PHB was highly expressed in many kinds of cancer tissues, especially in invasive breast cancer where the gene mutation and expression changes of PHB had higher proportion. The expression level of PHB had good diagnostic efficacy for BC (P＜0.01). The expression level of PHB was significantly correlated with the expressions of ER and HER2, PAM50 typing and tumor purity of BC patients (P＜0.05). The survival analysis showed that the high expression of PHB was an independent risk factor of BC (P＜0.01). [STBX]HRAS, KSR1[STBZ] and ARAF interacted with PHB, with significant correlation. The changed expressions of [STBX]HRAS, KSR1[STBZ] and ARAF could be found in BC tissues. @*Conclusion@#The expression of PHB increases in various cancer tissues such as breast cancer, ovarian cancer and so on. The high expression of PHB has significant influence on the prognosis of BC patients. The expression of PHB has good diagnostic efficacy for BC, which may be used as a potential marker for the diagnosis and prognosis of BC.

Initial research on the brain functional magnetic resonance imaging induced by olfactory stimulations in multiple sclerosis / 中华神经科杂志

Objective To observe the characteristics of brain activation of multiple sclerosis (MS) patients and healthy controls at functional magnetic resonance imaging (fMRI) with olfactory stimulation,determine the locations of activation in areas of olfactory center and explore the MS olfactory related network.Methods Eighteen MS patients from the Affiliated Hospital of North Sichuan Medical College from February 2017 to March 2018 were enrolled as MS group,and 20 matched healthy adults during the same period served as controls.The Visual Analogue Scale was used to evaluate olfactory function in all subjects,the rest structure MRI was performed first,and volatile gases of lavender and rose solution were used to alternately stimulate olfactory during fMRI scanning.The brain activation was obtained by using matlab2013a and SPM8 softwares.The distribution and quantity of demyelination lesions were counted on T2 weighted image,and Spearman correlation analysis was done with SPSS 17.0 software package.Results The activated brain areas in the healthy control group included bilateral middle frontal gyrus,bilateral insula,bilateral supramarginal gyrus,bilateral orbitofrontal gyrus,right thalamus,right central anterior gyrus,bilateral cingulated gyrus,bilateral hippocampus,bilateral amygdala and bilateral superior frontal gyrus (t =2.11,P＜0.05).The activated brain areas in the MS group included right cerebellum,left insula,left superior temporal gyrus,right inferior frontal gyrus (t=2.19,P＜0.05).Compared with the control group,the MS group showed statistically significant decrease in activated values in right insula,right amygdala,right inferior frontal gyrus,right frontal middle gyrus,and the left supramarginal gyrus (t=2.04,P＜0.05).The distribution and number of demyelination lesions and major activation of brain regions with olfactory in the MS group demonstrated no significant correlation (r=-0.524,P=0.054).Conclusions Multiple brain areas involved in the olfactory processing and olfactory-related brain network existed.The activation of olfactory center had dominance in the right brain.The activation of the brain area in the MS group was significantly reduced,and the activation voxel and activation intensity were weakened.The olfactory-related brain network changed in MS patients.The distribution and number of demyelination lesions had no significant effect on the major activation of brain regions with olfactory stimulation.
