Objective]Discussion on academic ideas and clinical experience of Professor Wang Xu in treating of throid-associated ophthalmopathy from liver, spleen and kidney.[Methods]From the relationship of etiology and pathogenesis, clinical manifestation, prognosis and therapy with liver, spleen and kidney to expound the academic viewpoints and clinical experience of Professor Wang Xu in treatment of TAO. The course of TAO is divided into early stage, middle stage and advanced stage. Early stage should be treated from the liver, middle stage should be treated from the spleen, and advanced stage should be treated from the kidney.In the end, we examplify that. [Results] Professor Wang Xu believes the liver, spleen and kidney in Chinese Medicine sense have close relationship on TAO. The pathogenesis of this disease is “Liver stagnation transforming into fire and phlegm, phlegm fire disturbing orifice and damaging liver and kidney after a long time”, phlegm and blood stasis are the important pathological factors. Thus, the treatment of TAO focusing on liver, spleen and kidney is proposed. Clearing liver and nourishing liver yin, strengthening the spleen and removing dampness, dissipating phlegm and activating blood, nourishing Yin of liver and kidney is the clinical common therapy, clinically obtaining better therapeutic effect. [Conclusion] The clinical experience of Professor Wang Xu in treatment of TAO is effective, has the value of popularization and application.

Objective To investigate muscle MRI characteristics of lower limbs in Chinese patients with dysferlinopathy. Methods Detailed clinical information of 42 patients with dysferlinopathy confirmed by Western blot or DYSF genetic test were studied retrospectively, including age, course, serum creatinine kinase (CK) and modified Gardner?Medwin and Walto score, and T1WI, STIR image. Each muscle was scored according to its fatty degeneration evaluated on T1WI (fat replacement score). The patients were divided into 3 groups:Miyoshi myopathy (MM), limb girdle muscle dystrophy 2B (LGMD 2B) and preclinical stage (asymptomatic hyperCKemia or exercise intolerance). The data including the scores of each muscle between MM and LGMD 2B were compared by ANOVA analysis and Chi square test. The relationship of fatty replacement score with course and GM?W score was analyzed by Spearman rank correlation analysis. Results Thirty nine patients underwent thigh MR scanning and 36 patients underwent leg MR scanning. At the thigh level, there is no specificity that the fatty replacement was found in both the anterior and posterior parts while the rectus femoris, sartorius and gracilis were rarely involved. At the leg level, the most severely involved muscle was the soleus, followed by gastrocnemius. It formed a sandwich?like pattern that the anterior part (anterior and posterior tibial muscle and peroneus longus muscle) and the posterior part (medial and lateral gastrocnemius) were less involved than the middle part (soleus). Of 42 patients, 14 cases were MM, and 24 were LGMD 2B. The fat replacement score of each muscle between two groups showed no significant differences (F=0.066 to 3.907,P all>0.05) except for the adductor muscle (F=5.239, P=0.028), semimembranosus (F=6.703, P=0.014) and semitendinosus (F=7.689, P=0.009). Of 4 pre?symptomatic cases, 3 showed edema of posterior part of leg on STIR, especially soleus. In all patients, the fat replacement score correlated positively with course (rs=0.732, P=0.000) and GM-W score (rs=0.485, P=0.001). Conclusions The MRI of Chinese patient with dysferlinopathy was characterized by the milder involvement of rectus femoris, sartorius and gracilis muscle in the thigh and a sandwich?like pattern in the leg, which is helpful for differential diagnosis of inflammatory Myopathy versus other types of muscular dystrophy.

Objective To summarize the characteristic of muscle MRI of lower limbs in patients with GNE myopathy and to explore the correlation between the fatty degenerative score of muscle MRI and clinical phenotype.Methods This was a prospective study. Seventeen patients with genetically confirmed GNE myopathy,having lower limb muscle MRI test and completed clinical and laboratory data.The degree of fatty degeneration in 18 muscles of lower limbs in each patient was grading.According to the GM-W score, these patients were divided into two groups.GM-W score≤3 were divided into mild group(n=8)and GM-W score≥ 4 were divided into severe group(n=9). Kruskal-Wallis test was used to compare the fatty degenerative score in different muscles of the thigh and the calf level;Mann-Whitney U test was used to compare score of the same muscle between mild and severe group;Spearman rank correlation test was used to analysis the relationship between fatty degenerative score and the course of disease (year), GM-W score, creatinine kinase (IU/L), respectively.Results At the thigh level, the most severely involved muscle of GNE myopathy was semi-tendinosusand adductor, followed by semi-membranous, biceps femoris and gracilis. There was no statistically significant difference in the fatty degenerative score of the above-mentioned muscles (P=0.058). At the calf level, the most severely involved muscle was medial of soleus which score was 4.0(3.0, 4.0), followed by tibialis anterior,extensor digitorum longus and lateral of soleus. There was no significant difference of the above (P=0.259).The fatty degenerative score showed difference between the mild and severe group at sartorius and adductor(P<0.05).At the calf level,the fatty degenerative score in peroneus longus, medial of soleus, lateral of soleus, medial of gastrocnemius and lateral of gastrocnemius showed difference between groups(P<0.05).The total score of fatty degenerative of Lower limb muscles was positively correlated with GM-W score(r=0.730, P<0.05). There were positive correlations between the score of fatty degenerative of the sartorius,peroneal longus,lateral of soleus,medial of gastrocnemius, lateral of gastrocnemius and the GM-W scores( r=0.630,0.845,0.569,0.591,0.640, 0.659,P<0.05).The total score of fatty degenerative of Lower limb muscles was not correlated with the level of creatine kinase(P=0.582), course of disease(P=0.601) and age of onset(P=0.850). Conclusions GNE myopathy in the thigh level within the adductor muscle and posterior muscle involvement, calf level to the tibial anterior muscle early involvement. The total score of fatty degenerative of lower limb muscles is positively correlated with GM-W score,but not correlated with the level of creatine kinase,course of disease and age of onset.

Objective:To investigate the clinical features, imaging features and gene mutation of a paitent with alanyl-transfer ribonucleic acid synthetase 2 (AARS2) gene mutation- related leukodystrophy and further improve the understanding of this rare disease.Methods:Clinical data of a patient with leukodystrophy associated with AARS2 gene mutation diagnosed in October 2020 at Xiamen Hospital of Beijing University of Chinese Medicine and Huashan Hospital of Fudan University were collected.Results:The male patient, 25 years old, was admitted with the clinical manifestations, including chronic onset dyskinesia, ataxia, nystagmus and psoriasis. Head magnetic resonance imaging (MRI) showed bilateral white matter lesions and cerebellar atrophy. Spine MRI showed vertebral body incomplete fusion. Gene detection showed heterozygous compound AARS2 gene mutation [c.985C>T chr6:44275041(p.R329C) and c.452T>C chr6:44279256(p.M151T)].Conclusions:AARS2 gene mutation-related leukodystrophy is a rare mitochondrial disease in clinical practice. The patient presented with progressive motor deficits in the lower limbs, ataxia, relatively retained cognitive function. MRI revealed abnormal symmetry of corpus callosum and bilateral paraventricular white matter. Heterozygous compound AARS2 gene mutations [c.985C>T chr6:44275041 (p.R329C) and c.452T>C chr6:44279256 (p.M151T)] are one of the pathogenic factors leading to hereditary leukodystrophy.

OBJECTIVES: Vagus nerve stimulation (VNS) is a neuromodulative therapeutic technique for patients with drug-resistant epilepsy who are not suitable for resection or who have experienced a failed resection. This study aims to explore the efficacy and safety of VNS in patients with refractory epilepsy, and to analyze the influential factors for the efficacy. METHODS: A retrospective review of clinical data were conducted for 35 patients, who were treated for refractory epilepsy through VNS surgery in the Department of Neurosurgery, Xiangya Hospital, Central South University from April 2016 to August 2019. All patients were analyzed in terms of the clinical and follow-up data. RESULTS: After a mean follow-up of 26 months (6-47 months), outcome was as follows: 7 patients were MuHugh class I, 13 patients were MuHugh class II, 8 patients were MuHugh class III, and 7 patients were MuHugh class IV-V. The total efficacy rate in the short duration group was significantly higher than that in the long duration group (77.8% vs 50.0%, CONCLUSIONS VNS is a safe and effective option in treating patients with refractory epilepsy, especially for those with short duration.
